Before explaining the embodiments, the explanation of the terms of the present invention will be explained.
[louver material]
A louver is a series of long and narrow blades arranged parallel to each other at intervals. It is used in various places for the purpose of sunshade, ventilation, ventilation, blindfold, blockage, etc.
The louver material 4 is a unit member constituting a louver. A louver generally has a separable elongated louver plate, and each elongated louver plate is a structural unit. The louver material A type (4A) in FIG. 5A, the louver material B type (4B) in FIG. 5B, the louver material C type (4C) in FIG. 6, and the louver material D type (8D) in FIG. The louver material E type (8E) shown in FIG. 17 is a unit member in which elongated blades constitute a louver. Each sheet becomes the louver material 4 .

[Support member]
FIG. 1 is a front view of the louver panel body 2, a cross-sectional view between AA, a cross-sectional view between BB, a cross-sectional view between CC and DD in the front view, and an enlarged view of the rectangular area E. 3 is an explanatory diagram of a base material 95 and a support member 3. FIG. A louver material A (4A) is used for explanation as a representative example of the louver material 4, and the explanation of FIG. be.
A louver panel body 2 is formed by connecting a plurality of louver members 4, which are unit members, to a support member 3 and forming a unit so that it can be attached to a base member 95 as it is. The front view and cross-sectional view along AA in FIG. 1 are drawings for explaining the role of the intermediate aggregate 86. FIG. Since a plurality of louver members 4 are connected by intermediate aggregates 86 to form the louver panel body 2 , the intermediate aggregates 86 serve as supporting members 3 . The louver panel body 2 is assembled in a factory or the like by arranging the louver members 4 at intervals as designed and fastening them with screws 861 using the intermediate aggregates 86 .
Although the middle aggregate 86 was exemplified as the support member 3, if the louver members 4 can be attached at predetermined intervals and the louver panel body 2 can be used, the support member 3 can be any shape, structure, attachment position, and number. regardless of Therefore, various members play the role of the support member 3 while having other functions.
Middle aggregates 86 are also used as supporting members 3 in a D-type louver material (8D) shown in FIG. 15 which will be described later.
15(A) has the function of attaching the louver panel body 2 to the backing material 95, but as shown in FIG. Since it also has a unitizing function, it also serves as the support member 3 .

FIG. 17 is an explanatory diagram of the louver material E type (8E).
The louver material E type (8E) is one in which a plurality of inclined surface parts 82 modeled after the louver material 4 are integrally connected inside one panel plate part 87 . In the case of the E-type louver material (8E), the panel plate portion 87 functions as the support member 3 because the plurality of inclined surface portions 82 are formed integrally with the one panel plate portion 87 . Since the louver material E type (8E) is integrally formed with the panel plate portion 87, it is also the louver panel body 2. As shown in FIG.

[Backing material]
The attachment relationship between the base material 95 and the louver material 4 will be described with reference to the front view of FIG.
The base material 95 is a member that supports the louver panel body 2, and needs to be a strong member in order to firmly support the louver material 4 exposed to the elements. The base material 95 is preferably H-shaped steel, angle steel, or the like. Since the louver panel body 2 is made by assembling the louver members 4 with the intermediate aggregates 86 (supporting members) at predetermined intervals in advance, the end portion of the louver panel body 2 is brought into contact with the base material 95 to hold the louver panel body 2 together. By fastening the louver material 4 sheet by sheet with the fastening material 46, the attachment is completed.
Since there are a large number of louver members 4, it takes time to fasten each louver member 4 to the base member 95 at predetermined intervals. Since they are assembled to the louver panel body 2 with the intermediate aggregates 86 (supporting members) so that they are arranged in advance at intervals as designed, work efficiency is good.

[Horizontal part]
The lateral pieces are one of the features of the present invention. As shown in the enlarged view of the rectangular area E of FIG. Any of the horizontal pieces affects properties such as ventilation, lighting, blinding, and blocking.

[gap]
The enlarged view of the rectangular area E in FIG. 1 is an enlarged view of the rectangular area E attached to the BB sectional view. Although the details of the louver material 4 will be described later, the louver material 4 of the present invention has an inclined surface portion 41 that is characteristic of the louver blades. The amount of air blown from the outside to the inside changes by changing the mounting interval of the upper and lower louver members 4. - 特許庁
There are many gaps involved by the lower lateral piece 43 or the upper lateral piece 421, which affect the incoming wind.
For example, there is a lower gap 221 between the lower horizontal piece 43 of the louver material 4 located above and the upper horizontal piece 421 of the louver material 4 located below.
It is also a ventilation opening 222 (longitudinal gap) formed between the upper inner side 412 of the inclined surface portion of the upper louver material 4 and the upper horizontal piece portion 421 of the lower louver material 4 .
In addition, as shown in the explanatory diagram of the back gap 413 of the inclined surface part in FIG. Only when the louver material 4 is attached at a pitch), a gap 413 behind the inclined surface portion is formed between the back side of the inclined surface portion 41 of the upper louver material 4 and the upper lateral piece portion 421 of the lower louver material 4 . In a mode in which the upper horizontal piece 421 is long, the width of the inclined surface part back gap 413 formed between the upper horizontal piece 421 and the back surface of the inclined surface part 41 becomes small, and the amount of blown air changes.
Other gaps can also be formed, and the above example shows typical ones.
Ventilation, lighting, blinding, blocking, etc. are affected by the installation interval between the upper louver material 4 and the lower louver material 4, and the length of the upper horizontal piece 421 and the lower horizontal piece 43. can be varied, and the width of the gap is limited to change the characteristics.

A louver material 4 provided with only the upper horizontal piece 421 is included in the aspect of the present invention, and a louver material 4 provided with only the lower horizontal piece 43 is also included in the aspect of the present invention. When the louver material 4 is attached, the upper lateral piece 421 or the lower lateral piece 43 has some width of the gap. Of course, an aspect having both the upper horizontal piece 421 and the lower horizontal piece 43 is also included in the present invention.

These gaps affect characteristics such as ventilation, lighting, blinding, and occlusion. Which gap has the greatest effect depends on the installation interval between the upper and lower louver materials 4 and the , depending on the lengths of the upper horizontal piece 421 and the lower horizontal piece 43 .
For example, when the width of the ventilation opening 222 (longitudinal gap) is shortened and effectively closed, even if the width of the lower gap 221 is large, the air cannot be blown in and the closed portion 23 is formed.
Also, if the width of the lower gap 221 is greatly restricted and there is no room for the wind to blow in, the gap 413 behind the inclined surface portion and the ventilation opening 222 (vertical gap) may become the closed part 23 even if the width is wide.

[Mounting part]
The louver material 4 must be attached to the backing material 95 . The means of attachment to substrate 95 may vary in the present invention. As shown in the enlarged view of the rectangular area E in FIG. 1, a mounting portion 45 is provided on the upper portion of the back of the inclined surface portion, and a bag for accommodating a fastening material 46 such as a bolt so as to be fastened to the base material 95. A portion 451 is provided. The mounting interval of the louver material 4 may vary. As shown in FIG. 2, it is also possible to attach the lower louver material 4 at such intervals that the upper lateral piece 421 of the lower louver material 4 is swallowed inside the inclined surface portion 41 of the upper louver material 4 . When the lower louver member 4 in FIG. 2 is further raised and attached, the upper end 8a (upper horizontal piece portion 421) of the vertical piece portion 42 of the lower louver member 4 comes into contact with the upper inner side 412 of the inclined surface portion, which is the lower surface of the attachment portion 45. As a result, the ventilation opening 222 (longitudinal gap) disappears and becomes the closed portion 23 . The upper end 8a (upper horizontal piece 421) of the vertical piece 42 limits the width of the ventilation opening 222 (vertical gap).
The position where the mounting portion 45 is provided does not have to be the upper inner side 412 of the inclined surface portion. Moreover, when using the mounting bracket 9 of Example 2 or Example 3, which will be described later, the mounting portion 45 for fastening to the base material 95 is not required. Since the attachment portion 45 is eliminated, the area that becomes the ventilation opening 222 (vertical gap) is enlarged.

[Length of horizontal piece]
The lengths of the lower horizontal piece 43 and the upper horizontal piece 421 can be appropriately determined according to desired characteristics such as ventilation, lighting, blinding, and blocking. To give an example, in the example of FIG. 2, since the length of the upper horizontal piece 421 is shorter than the width of the lower surface of the mounting portion 45, the upper end 8a of the vertical piece 42 (upper horizontal piece) is attached to the lower surface of the mounting portion 45 (upper horizontal piece). 421) could abut.
If the length of the upper horizontal piece portion 421 is longer than the lower surface of the mounting portion 45 , the tip of the upper horizontal piece portion 421 of the lower louver material 4 will reach the top of the upper louver material 4 before contacting the lower surface of the mounting portion 45 . It abuts on the back surface of the inclined surface portion 41 , and the inclined surface portion back gap 413 is limited and disappears to become the closed portion 23 . A ventilation opening 222 (vertical gap) remains between the vertical piece 42 and the upper end 8b (upper horizontal piece 421), but since the inclined surface portion back gap 413 is the closed portion 23, ventilation is lost.
The length of the lower lateral piece 43 can also be varied to affect the width of the various gaps.

(Example 1)
Example 1 is an example of the louver panel body 2 provided on the scaffolding 7 provided below or on the side of the elevated structure 5 . The scaffolding 7 is an example of the structure 1 on which the louver panel body 2 is provided.

[Overall scaffold structure]
FIG. 3 is a schematic diagram of Example 1. FIG. 3A is a sectional view of the viaduct 5, and FIG. 3B is a side view of the viaduct 5. FIG. A scaffolding 7 is shown provided under the overpass 5 . Below the road surface material 52, underpass members such as a plate girder 51 for supporting the road surface material 52 are provided. Work is being carried out to install the scaffolding 7 between the legs 53 , and the horizontal beams 75 of the scaffolding 7 are supported by being connected to the underpass members such as the plate girder 51 via the horizontal beam support members 77 . there is Along with the extension of the scaffolding 7, the louver panel bodies 2 are attached one after another to the left and right side surfaces of the elevated structure 5 to form the structure 1. - 特許庁

FIG. 4 is a cross-sectional view of the viaduct 5 and an enlarged view of the frame a shown in the cross-sectional view. The scaffolding 7 can be attached to some underpass member, but is preferably a strong member such as a box girder or a plate girder 51 . In Example 1, a plurality of cross beam support members 77 are attached to the plate girder (underpass member) 51 to support the cross beam 75 of the scaffolding 7 . If there is no strong member above the cross beam 75, auxiliary members 774 can be attached to the sides of the plate girder (elevated lower member) 51 as shown in FIG. Auxiliary members 774 are attached, and the cross-beam support member 77 can also be used as a base member 95 to which the louver panel body 2 is attached.

The louver material 4 shown in Example 1 has three types as shown in FIGS. Louver material A type (4A), louver material B type (4B) and louver material C type (4C). 5(A) is a side view of a louver material A type (4A), FIG. 5(B) is a side view of a louver material B type (4B), and FIG. 6 is a side view of a louver material C type (4C). It is a diagram.
The three types have a common structure in the following points.

[Inclined part]
All the molds have the same shape and size of the inclined surface portion 41 . A part of the inclined surface portion 41 may be an inclined surface. In Example 1, the lower end of the inclined surface portion 41 is a vertical surface 411 . The vertical surface 411 may not be present, and it is preferable that the inclined surface portion 41 is conspicuous in appearance.

[Mounting part]
The mounting portions 45 forming part of the inclined surface portion 41 are formed to have the same shape and size in all three molds. Although the position of the mounting portion 45 is appropriate, it is provided inside the inclined surface portion 41 in the first embodiment. Moreover, the attachment of the louver material 4 can be performed from the scaffolding 7 side.

A bag portion 451 is provided in the mounting portion 45 . The bag portion 451 has a structure into which the fastening material 46 such as a nut or bolt head for attaching the louver material 4 to the backing material 95 can be inserted. The bag portion 451 is formed to have substantially the same size as the head of the nut or bolt, and functions as a detent for the nut or bolt. The bag portion 451 contributes to improvement in work efficiency when fastening the louver material 4 to the base material 95 . The louver material 4 can be fastened from the base material 95 side (scaffold 7 side), and since the fastening material 46 is stored in the bag portion 451, the fastening material 46 may be exposed on the front side of the louver material 4. Absent.

[Lower horizontal piece]
The “lower horizontal piece portion 43”, which is one aspect of the “horizontal piece portion” in the present invention, will be described.
The three types of louver material A type (4A) to louver material C type (4C), which will be described later, all have a lower horizontal piece portion 43 extending inward from the lower end 8b of the inclined surface portion 41 of the louver material 4 in common. It has the characteristics of This feature will be described with reference to FIG. 5(A) relating to the louver material type A (4A) and FIG. 5(B) relating to the louver material type B (4B).
When a plurality of louver members 4 are attached to the base member 95 in the vertical direction to form a louver, the lower horizontal piece portion 43 has the following functions. As shown in FIG. 5B, the lower horizontal piece 43 is formed between the lower horizontal piece 43 of the louver material 4 located above in side view and the vertical piece 42 of the louver material 4 located therebelow. It limits the length of the width (ventilation) between the lower gaps 221 . As shown in FIG. 5A, when an upper horizontal piece 421 is provided and the lower horizontal piece 43 and the upper horizontal piece 421 face each other, the lower horizontal piece of the upper louver material 4 A lower gap 221 is formed between the portion 43 and the upper lateral piece portion 421 of the lower louver material 4 .

[Upper horizontal piece]
The three types all have an upper lateral piece 421 extending outward from the upper end of the louver material 4 (vertical piece upper end 422). When a plurality of louver members 4 are attached to the base member 95 in the vertical direction to form a louver, the upper horizontal piece portion 421 has the upper louver member 4 and the lower louver member 4 in side view. It affects the width of the lower gap 221 formed between the upper horizontal piece 421 of the louver material 4 and the air permeability between the louver materials 4 .
In addition, the upper horizontal piece portion 421 of the lower louver material 4 has a ventilation opening 222 (longitudinal gap ) and restricts ventilation.
In the case of the louver material 4 without the lower horizontal piece 43, the upper horizontal piece 421 of the louver material 4 located below is between the inclined surface portion upper inner side 412 of the inclined surface portion 41 of the louver material 4 located above in side view. This limits the length of the width of the ventilation opening 222 (vertical gap) that is created.
That is, both the lower horizontal piece 43 and the upper horizontal piece 421 limit the width of the lower gap 221 in the direction of projection and the width of the ventilation opening 222 (vertical gap), which is the gap in the vertical direction.

[Louver material A type]
Louver material type A (4A) is the most basic type. It has the shortest vertical piece 42 among the three types. The term “short length” as used herein means a length shorter than the vertical dimension of the inclined surface portion 41 . The vertical piece portion 42 extends upward from the upper end of the inclined surface portion 41 so as to follow the base material 95 when attached to the base material 95 .
The lower horizontal piece portion 43 is a short member extending inward from the lower end 8b of the inclined surface portion 41 . The short length here means a short length in which a lower gap 221 through which air passes is formed between the base material 95 and the lower horizontal piece 43 when the louver material A type (4A) is attached to the base material 95. be. Although the lower horizontal piece 43 is short, it has the effect of restricting ventilation when attached to the base material 95 .

It also has an upper horizontal piece portion 421 extending outward from a vertical piece portion upper end 422 which is the upper end of the louver material A type (4A). When a plurality of A-type louver materials (4A) are attached in the vertical direction to the base material 95 to form the louver panel body 2, the lower horizontal piece portion 43 of the A-type louver material (4A) located above in side view and the lower horizontal piece portion 43 therebelow. It affects the length of the width of the lower gap 221 formed between the upper end of the louver material A type (4A) at , that is, the upper end 422 of the vertical piece (upper horizontal piece 421).
In this way, both the lower horizontal piece 43 and the upper end 422 of the vertical piece (upper horizontal piece 421) are the louver material type A (4A) above and the louver material type A (4A) below it in a side view. ) to limit the ventilation between Even in a mode in which only one of the lower horizontal piece 43 and the vertical piece upper end 422 (upper horizontal piece 421) is provided, the function of limiting the width of the lower gap 221 is not lost.

When a plurality of A-type louver members (4A) are attached to the support member 3 in the vertical direction to form the louver panel body 2, the upper end of the vertical piece portion 422, which is the upper end of the A-shaped louver member (4A), is directed outward. The upper horizontal piece portion 421 extending along the length of the upper portion 421 has the following functions. Between the upper louver material A type (4A) and the lower louver material A type (4A), ventilation openings 222 (vertical gaps) are formed vertically on the back side. The upper edge 422 (upper horizontal piece 421) of the lower louver material A type (4A) forms a part of the ventilation opening 222 (vertical gap), and passes through the ventilation opening 222 (vertical gap) to the inside. limit the ventilation of the wind entering the
As described above, the lower horizontal piece portion 43 and the upper horizontal piece portion 421, which are the horizontal pieces, restrict the ventilation and mainly affect the blindability, the ventilation, and the lighting.

When the vertical piece 42 of the louver material A (4A) below the lower horizontal piece 43 of the louver material A (4A) above is spaced apart from the lower horizontal piece 43 of the louver material A (4A), the lower horizontal piece 4A is placed. Since the piece portion 43 is short and the width of the lower gap 221 is wide, the type has high ventilation through which the air flows from the inside of the inclined surface portion 41. - 特許庁
Although the details will be described later, the louver material A type (4A) can be made into the ventilation/lighting part 21 and the ventilation/blinding part 22 by adjusting the mounting interval.
At this time, the upper horizontal piece 421 works together with the lower horizontal piece 43 to limit the width of the lower gap 221 and make it difficult to see inside the louver panel body 2, so that it functions as a blindfold. help improve.

[Louver material B type]
Comparing the louver material type A (4A) in FIG. 5A with the louver material type B (4B) in FIG. It differs from the louver material type A (4A) only in that it is longer than the material type A (4A).
Similar to the louver material A type (4A), the louver material B type (4B) has an upper horizontal piece portion 421 extending outward from the upper end (vertical piece upper end 422).
Although the details will be described later, the louver material type B (4B) has a higher closing property than the louver material type A (4A) even if the installation interval (pitch) is changed.

When the louver material B type (4B) is attached vertically, the lower horizontal piece 43 of the louver material B type (4B) is significantly longer than that of the louver material A type (4A). The width of the lower gap 221 formed between the lower horizontal piece 43 of the material B type (4B) and the vertical piece 42 of the underlying louver material B is reduced, and the ventilation from the lower gap 221 is greatly restricted. be.
Since the louver material B type (4B) has a long lower horizontal piece part 43, even if the louver material B type (4B) is installed vertically apart so as not to overlap, the air hardly flows inside the inclined surface part 41.例文帳に追加The louver material B type (4B) is a type that emphasizes a relatively closed property, and is a type that can be used as the ventilation/lighting section 21 and the blocking section 23 by adjusting the installation interval.

[Louver material C type]
FIG. 6 is a side view of the louver material C type (4C), which differs from the louver material type A (4A) only in that the length of the vertical piece 42 is longer.
The lower horizontal piece portion 43 of the louver material C type (4C) is short like the louver material A type (4A) (a short length in which a lower gap 221 through which air passes is formed on the lower side of the louver material C type (4C)). be.
The length of the vertical piece portion 42 extending upward from the upper end of the inclined surface portion 41 is longer than the vertical dimension of the inclined surface portion 41 .
Since the louver material C type (4C) has a longer vertical piece 42 than the louver material A type (4A), the occlusion property is high even if the mounting interval in the vertical direction is increased. Although details will be described later, it is characterized by being a type that can be any of the ventilation/lighting section 21, the ventilation/blinding section 22, or the blocking section 23 by adjusting the mounting interval (pitch) in the vertical direction.

In particular, since the vertical piece 42 of the louver material C type (4C) is long, the position of the vertical piece upper end 422 (upper horizontal piece 421) is high, and the louver material C type (4C) located above in side view. 4C) and the ventilation opening 222 made on the back side of the louver material C type (4C), which leads inward through the vertical piece part upper end 422 (upper horizontal piece part 421) of the louver material C type (4C) below it. (vertical gap) width is greatly restricted. In the louver material C type (4C), even if the width of the lower gap 221 is large, the width of the ventilation opening 222 (vertical gap) tends to be small. .

(Other type variations)
The louver material 4 may be of various types other than the louver material type A (4A), louver material type B (4B), and louver material type C (4C) presented as examples.
What is common to each mold of the louver material 4 constituting the louver panel body 2 is the lower horizontal piece portion 43 or the upper horizontal piece portion 421, and variation can be increased by varying the length of this portion. Even if only one type of louver material 4 is used, the louver panel body 2 provided with ventilation/lighting parts 21 with different degrees of ventilation and lighting can be obtained by changing the mounting interval (pitch).

[Mounting example]
Examples of attaching each type of louver material 4 to the scaffolding 7 are shown below, but attachment methods other than the attachment examples are not excluded and are shown as examples.

FIG. 7 is a drawing showing an example of attachment of the louver material A type (4A). In the example of FIG. 7, the louver material A type (4A) in the figure is all the same and has a vertical dimension of 60 mm.

FIG. 7(A) is a side view showing an example of mounting the comparison reference, FIG. 7(B) is a side view showing an example of mounting with a wider mounting interval (pitch), and FIG. ) is a side view showing an example of attachment for narrowing.
Note that FIG. 7A is a comparison reference diagram for explaining the influence of the mounting interval (pitch). The mounting interval (pitch) shown in FIG. 7A is not recommended as a standard, nor is it a preferable mounting interval (pitch). The optimal mounting interval (pitch) of the louver members 4 differs depending on the environment around the place where the louver members 4 are to be provided and the required lighting.

See FIG. 7(A) and an enlarged view of a portion thereof. As with any type of louver panel body 2, the inclined surface portion 41 side with respect to the base material 95 is outside, and the scaffolding 7 side across the base material 95 is inside. The lower horizontal piece portion 43 of the upper louver material A type (4A) and the vertical piece portion 42 of the lower louver material A type (4A) are attached so as to be separated from each other when viewed from the front. A light opening 213 formed between the separated upper and lower louver material A type (4A) is set to 10 mm. Wind and light enter the inside of the scaffolding 7 through the light openings 213, but since the inside can be seen through the light openings 213, the inside cannot be concealed.

The distance between the A-type louver material (4A) attached to the base material 95 in the vertical direction is the lower horizontal piece 43 of the A-type louver material (4A) above and the A-type louver material (4A) attached below. can be measured as the distance from the lower lateral piece portion 43 of the mounting, which is 70 mm in this mounting example.
Further, the plurality of A-type louver materials (4A) are composed of a lower horizontal piece portion 43 of the upper louver material A-type (4A) and an upper vertical piece portion upper end 422 (upper horizontal piece) of the A-type louver material (4A) below. A lighting opening 213 is formed between the part 421). Furthermore, the scaffolding 7 is placed between the upper inner side 412 of the inclined surface portion of the upper louver material A (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece portion of the lower louver material A (4A). A louver material A-type (4A) ventilation opening 222 (longitudinal gap) leading to the inside is formed, and part of it becomes a lighting opening 213 .
This installation example is an installation example of a louver material A type (4A) that serves as the ventilation/lighting section 21 .

FIG. 7(B) is an example of attachment that emphasizes ventilation and lighting. The mounting example of FIG. 7B is a mounting example of the louver material A type (4A) which becomes the same ventilation/lighting part 21 as in FIG. The mounting interval in the vertical direction with respect to 95 is 80 mm, which is wider than that in FIG. Compared to the comparison standard in FIG. 7A, the performance of concealment, rain prevention, and object drop prevention is lowered, but ventilation and lighting are improved. In FIG. 7(B), the working environment is improved because the air is brighter and easier to pass through than in FIG. 7(A) of the comparison standard.

FIG. 7(C) is an example of attachment that emphasizes the prevention of rain intrusion and the prevention of objects from falling. The vertical mounting interval of the A-type louver material (4A) with respect to the base material 95 is such that the lower horizontal piece portion 43 of the A-type louver material above and the vertical piece portion 42 of the A-type louver material (4A) below. , are installed so as to overlap when viewed from the front. In terms of engagement margin, it is minus 10 mm, and the vertical piece upper end 422 (upper horizontal piece 421) of the lower louver material A type (4A) is aligned with the upper louver material A type (4A). It is swallowed inside the inclined surface portion 41 . For this reason, there is no lighting opening 213 through which the inside of the louver panel body 2 can be directly seen in a front view as shown in FIG. 7(B).
Although the light opening 213 has disappeared, the lower horizontal piece 43 of the upper louver material A (4A) and the vertical piece 43 of the lower louver material A (4A) are shown in side view. A lower gap 221 is formed between the upper end 422 (upper horizontal piece portion 421). Between the upper inner side 412 of the inclined surface portion of the A-type louver material (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece portion of the A-type louver material (4A) located below when viewed from the side, A ventilation opening 222 (longitudinal gap) leading to the inside of the scaffolding 7 is formed.

Therefore, the wind entering from the lower gap 221 enters the inside of the inclined surface portion 41 as indicated by the arrow, and can enter the scaffolding 7 (inside) through the ventilation opening 222 (vertical gap). Although the ventilation opening 222 (longitudinal gap) is narrower than that shown in FIG. 7A, which is the standard for comparison, it has ventilation, but it is a ventilation/blind part where the inside cannot be seen from the front. Although the mounting interval (pitch) of the louver material A type (4A) has been described, the mounting interval (pitch) of the louver material type B (4B) and louver material C type (4C) can be similarly changed as appropriate.

[Mounting example with matching appearance]
FIG. 8 is an explanatory diagram of appearance matching. The vertical dimension of the louver material type A (4A) and louver material type B (4B) in FIG. 8 is 60 mm, and the louver material type C (4C) is 80 mm.
The mounting interval (pitch) of the louver material 4 can be expressed as the distance between the lower horizontal piece portion 43 of the louver material 4 and the lower horizontal piece portion 43 of the louver material 4 mounted therebelow.
FIG. 8A shows the louver panel body 2 using the louver material A type (4A), and the louver material A type (4A) is installed at a mounting interval (pitch) of 70 mm so that the light opening 213 is 10 mm. This is an example of attachment to form the ventilation/lighting section 21. FIG. In side view, the lower horizontal piece 43 of the upper louver material A (4A) and the upper end 422 (upper horizontal piece 421 ), a lower gap 221 is provided between them. The ventilation opening 222 (longitudinal gap) on the back side of the louver material 4 is large and has good ventilation.

FIG. 8(B) shows the louver panel body 2 using the louver material B type (4B). This is an example of attachment to form the ventilation/lighting section 21. FIG. The B-type louver material (4B) has a lower horizontal piece portion 43 extending inward from the lower end 8b of the inclined surface portion 41 to a position substantially directly below the vertical piece portion 42. As shown in FIG.
Since the lower horizontal piece portion 43 of the louver material B type (4B) is long, no matter what the mounting interval (pitch) is, the louver material B type (4B) above and below it in a side view The width of the lower gap 221 formed between the louver material B-types (4B) at the bottom is greatly restricted. The long lower horizontal piece portion 43 of the louver material B type (4B) allows only a small amount of air to pass inside the inclined surface portion 41 of the louver material B type (4B) even with the lower horizontal piece portion 43 alone. It substantially closes the place where the mold (4B) is attached.
The area functioning as the ventilation/lighting part 21 is the ventilation opening 222 between the lower horizontal piece 43 of the upper louver material B type (4B) and the vertical piece upper end 422 of the lower louver material B type (4B). (longitudinal gap). The mounting example of the louver material A type (4A) in FIG. 8A and the mounting example of the louver material B type (4B) in FIG. The example of attachment in FIG. 8A emphasizes ventilation, and the example of attachment in FIG. 8B emphasizes wind protection. The mounting example of FIG. 8(B) can be used for scaffolding 7 under a bridge, which is often exposed to strong winds.

The louver panel body 2 using the louver material A type (4A) with a vertical dimension of 60 mm in FIG. 8(A) and the louver material B type (4B) with a vertical dimension of 60 mm in FIG. (Pitch) is 10 mm, and a light-receiving opening 213 is formed. The intervals of the inclined surface portions 41 that are conspicuous when viewed from the outside are completely the same, and at first glance they are indistinguishable.

FIG. 8(C) shows the louver panel body 2 using the louver material C type (4C), and the louver material C type (4C) is attached at an attachment interval (pitch) of 60 mm. In Example 1, the upper inner side 412 of the inclined surface portion with the mounting portion 45 of the upper louver material C type (4C) and the upper horizontal piece portion at the upper end 422 of the vertical piece portion of the lower louver material C type (4C) 421 is designed to just abut. Therefore, it is possible to attach the louver material C-type (4C) at a pitch of 60 mm by simply contacting the vertical piece 42 of the lower louver material C-type (4C) with the mounting portion 45 of the upper louver material C-type (4C). It is possible. The vertical dimension of the louver material C type (4C) is 80 mm, but the vertical piece 42 of the lower louver material C type (4C) is swallowed inside the upper inclined surface 41, and the overlapping margin is -20 mm. It's becoming
In the mounting example of FIG. 8(C), the mounting portion 45 inside the inclined surface portion 41 of the upper louver material C type (4C) and the vertical piece portion 42 of the lower louver material C type (4C) are in contact. In this mounting example, the ventilation opening 222 (longitudinal gap) on the back side of the louver material C type (4C) disappears because it is arranged so as to touch, and the closed part 23 has no ventilation or lighting.
Both of the louver material A type (4A) and the louver material type A (4A) shown in FIG. When the louver material B type (4B) in FIG. 8B is arranged side by side, it can be seen that there is a deviation in appearance, but it is not so conspicuous. Then, when the louver panel body 2 of the louver material A type (4A) of FIG. 8A is provided below and the louver panel body 2 of the louver material C type (4C) of FIG. The difference in appearance becomes inconspicuous.

The louver panel body 2 in which the louver material A type (4A) to the louver material C type (4C) are arranged at the same mounting interval (pitch) has an inclined appearance even if the louver panel bodies 2 of different types are arranged on the left and right. The positions of the surface portions 41 are matched, and they are indistinguishable.
By adjusting only the mounting interval (pitch), the same appearance can be obtained regardless of the type of louver material 4 used.

[Mounting interval (pitch) change]
FIG. 9 is an explanatory diagram of changing the mounting interval (pitch). By combining the type of the louver material 4 to be adopted and the mounting interval (pitch), the lighting, ventilation, blinding, and blocking properties can be appropriately adjusted. FIG. 9A shows an example in which the louver material A type (4A) is used, the installation interval is set to 80 mm, and the ventilation/lighting section 21 is used. The light opening 213 is wider by 20 mm than in FIG. 8(A). Since the mounting interval (pitch) is wider than that in FIG. 8A, more light enters inside the louver panel body 2 . The mounting examples of FIGS. 8A and 9A are both examples in which the louver material A type (4A) is used as the ventilation/lighting section 21, but in the example of FIG. 9A, the mounting interval is widened. Thus, it is possible to improve lighting and ventilation as compared with the example of FIG. 8(A).

FIG. 9(B) is an example of installation using the louver material C type (4C), setting the installation interval to 80 mm, and using the ventilation/blinding part 22 . As described above, the inclined surfaces 41 of the louver material A (4A) to the louver material C (4C) are arranged at the same mounting interval (pitch). 9A using louver material type A (4A) and FIG. Even though the intervals are uniform and different types of louver materials 4 are used, the external appearance is almost the same.

[Limitation of gap by upper horizontal piece and lower horizontal piece]
Various mounting examples of the louver material type A (4A) to the louver material type C (4C) have been described above. The restriction of the gap by the upper horizontal piece portion 421 and the lower horizontal piece portion 43 will be described in order. As described above, the upper horizontal piece 421 and the lower horizontal piece 43 are both elements that form the lower gap 221 , and the width of the lower gap 221 can be limited by having one of them. When the length of the upper horizontal piece portion 421 or the lower horizontal piece portion 43 is lengthened, the width of the lower gap 221 becomes narrower.
Further, the upper horizontal piece portion 421 limits the width of the ventilation opening 222 (vertical gap) by changing the mounting interval of the louver material 4 .

Any one having either one of the upper horizontal piece portion 421 and the lower horizontal piece portion 43 is included in the present invention. Example 1 is an example in which both the upper horizontal piece portion 421 and the lower horizontal piece portion 43 are provided. When the lower horizontal piece portion 43 is extremely long like the louver material B type (4B), the lower gap 221 is greatly restricted regardless of the installation interval, and the air flow is substantially directed to the inside of the inclined surface portion 41. will not enter.
In addition, like the louver material C type (4C), in the case of the long vertical piece 42 provided with the upper horizontal piece 421, the ventilation opening 222 (vertical gap) is greatly restricted, and the upper louver material C type (4C) When the inclined surface portion upper inner side 412 and the lower louver material C type (4C) upper horizontal piece portion 421 are provided at a mounting interval that abuts, substantially inside through the ventilation opening 222 (longitudinal gap) wind will not enter.
As shown in FIG. 9(A), when the upper and lower louver material A type (4A) are attached separately, both the width of the lower gap 221 and the width of the ventilation opening 222 (vertical gap) are increased, and the ventilation and lighting part 21.
By restricting the gap between the upper horizontal piece portion 421 and the lower horizontal piece portion 43, various louver panel bodies 2 can be produced, such as emphasizing ventilation and windproofing.

FIG. 10 is an explanatory diagram of changing the mounting interval (pitch).
FIG. 10(A) is an example of installation in which the louver material A type (4A) is used, and the installation interval (pitch) is set to 60 mm, which is the same as the vertical dimension of the louver material 4, and the ventilation/blind area 22 is used. The lower horizontal piece portion 43 of the upper louver material A type (4A) is attached to the base material 95 so as to overlap the vertical piece portion 42 of the lower louver material A type (4A) in front view. In addition, in this mounting example, the lower horizontal piece 43 of the A-type louver material (4A) located above in side view and the upper end 422 of the vertical piece portion of the A-type louver material (4A) located therebelow are at approximately the same position. It is attached to the backing material 95 so that it becomes. When viewed from the side, a lower gap 221 is provided between the upper end 422 of the vertical piece and the lower horizontal piece 43, and the upper end 422 of the lower louver material A (4A) and the upper louver material A ( 4A) is installed so that a ventilation opening 222 (vertical gap) is left between the upper inner side 412 of the inclined surface portion of 4A), so that the ventilation/blind portion 22 has ventilation but the inside cannot be seen from the front. there is

FIG. 10(B) is an example of attachment using the louver material B type (4B), setting the attachment interval (pitch) to 60 mm, and using the closed portion 23 . The vertical mounting interval (pitch) of the louver material B type (4B) with respect to the base material 95 is the vertical piece 42 of the lower louver material B type (4B) and the upper louver material B type (4B). The ends of the lower horizontal piece portions 43 are attached so as to overlap each other in a side view to form the closing portion 23 .

The mounting interval (pitch) of the louver material B type (4B) is further narrowed to 50 mm, and the upper end 422 of the vertical piece of the lower louver material B type (4B) is aligned with the upper louver material B type (4B). Even when it is attached so as to be swallowed inside the inclined surface portion 41 , it substantially becomes the closed portion 23 .
10(A) using the louver material A type (4A) and FIG. 10(B) using the louver material B type (4B), the intervals of the inclined surfaces 41 are uniform because the mounting interval (pitch) is the same. , the appearance is the same despite the use of different types of louver material 4 .

[Flexibility]
As described above, in the present invention, there are three types of louver materials 4, and the mounting interval (pitch) of each type of louver material 4 can be changed. - The size of the lighting part 21 can be changed. When it is desired to ensure ventilation but also to have a function as a blindfold, the ventilation/blindfold portion 22 can be used to prevent rain from entering. In addition, the closing portion 23 can be used when priority is given to anti-dropping properties and shielding properties.

The present invention can be used in various places such as bridges exposed to strong winds and rain where windproofness and occlusiveness are important, places near sidewalks where blindness is important, and places where lighting is important to improve workability. The louver panel body 2 can be provided according to various situations and places. Furthermore, even if the characteristics are changed, since the shape of the inclined surface portion 41 is the same, a unified appearance can be achieved.

FIG. 11 is an illustration of flexibility. FIG. 11(A) shows an example of attachment of a louver material A type (4A) that serves as a reference for comparison, and is an example of the ventilation/lighting section 21 . The mounting interval (pitch) is 70 mm. It should be noted that this is a comparative standard for illustrating flexibility and is not a preferred or recommended example.

FIG. 11(B) is a side view of the louver panel body 2 with the mounting interval (pitch) widened by 80 mm. The same louver material A type (4A) as the comparison standard is used. Since the mounting interval (pitch) has been changed and made wider than the comparison standard, there is no difference from the comparison standard in terms of the ventilation/lighting section 21, but the mounting example in FIG. ) is expanded, the lighting and ventilation of the louver panel body 2 are improved.

FIG. 11(C) is a side view of the louver panel body 2 in which the mounting interval (pitch) is narrowed to 50 mm. The same louver material A type (4A) as the comparison standard is used. The louver panel body 2 has a ventilating/blinding part 22 because the mounting interval (pitch) is changed and narrowed from the comparison standard.

FIG. 11(D) is a side view of the louver panel body 2 with a modified mold. The louver panel body 2 of FIG. 11(D) adopts the louver material C type (4C), and the comparison standard and the type are changed. Although the mounting interval (pitch) is 70 mm, which is the same as the comparison standard, the louver panel body 2 has a closed portion 23 because the mold has been changed.

FIG. 11(E) is a side view of the louver panel body 2 in which mounting intervals (pitch) are used differently depending on the height. The louver material A type (4A) is used for both the upper part and the lower part of the louver panel body 2, but the mounting interval (pitch) is as wide as 70 mm in the upper part and narrow as 50 mm in the lower part. The mounting interval (pitch) of the lower part is 50 mm, which is narrower than the vertical dimension of the louver material A (4A), which is 60 mm. , -10 mm.
Therefore, the upper part is a ventilation/lighting part 21 and the lower part is a ventilation/blinding part 22. - 特許庁
When changing the mounting interval (pitch) in the vertical direction, it is preferable to change gradually. Changes in appearance are difficult to discern.

FIG. 11(F) is a side view of the louver panel body 2 in which different molds are used depending on the height. The mounting interval (pitch) of the louver material 4 is the same in the upper part and the lower part of the louver panel body 2, but the louver material A type (4A) is used in the upper part and the louver material B type (4B) is used in the lower part. there is Therefore, the upper part is a ventilation/lighting part 21, and the lower part is a ventilation/lighting part 21 that emphasizes wind protection.

[Aspects in which the upper and lower louver panel bodies are used by changing the shape and spacing]

It goes without saying that four or more types of louver members 4 may be prepared as long as they have a common inclined surface portion 41 .

(Example 2)
[Louver material D type]
The louver material 4 from the louver material A type (4A) to the louver material C type (4C) of Example 1 had both the upper horizontal piece portion 421 and the lower horizontal piece portion 43. FIG. FIG. 14 is a side view of the louver material D type (8D). As shown in the figure, the D-shaped louver material (8D) of Example 2 has the upper horizontal piece portion 84 at the upper end 8a of the vertical piece portion 88, but the lower horizontal piece portion 43 is formed at the lower end 8b of the inclined surface portion 82. It is a mode that does not have. When a plurality of D-type louver materials (8D) are vertically attached to form a louver panel body 2, the inside of the inclined surface portion 82 of the D-type louver material (8D) above in side view and the louver material below it. The length of the width of the lower gap 827 formed between the D-shaped (8D) upper end 8a and the upper horizontal piece 84 is limited. If the upper lateral piece 84 is lengthened, the width of the lower gap 827 is restricted and narrowed. In FIG. 14, since the lower end 8b of the inclined surface portion 82 of the upper D-shaped louver material (8D) faces the upper horizontal piece portion 84 (upper end 8a) of the lower D-shaped louver material (8D), A lower gap 827 is created at the location shown. If the upper horizontal piece 84 of the underlying D-shaped louver material (8D) is swallowed inside the sloped surface portion 82 of the D-shaped louver material (8D) located above, the slope facing the upper horizontal piece 84 A lower gap 827 is formed between the face portion 82 and the surface portion 82 .
The upper lateral piece 84 limits the length of the width of the lower gap 827 between the louver material 4 located above and the louver material 4 located therebelow when viewed from the side.

The upper horizontal piece 84 (upper end 8a) is between the hanging piece lower end 811 of the upper D-shaped louver material (8D) and the upper horizontal piece 84 (upper end 8a) of the lower D-shaped louver material (8D). The length of the width of the ventilation opening 826 (vertical gap) formed in the space is also limited. The installation interval (pitch) affects blindness, ventilation, and lighting.

Also, the D-shaped louver material (8D) has an inclined surface portion 82 that is inclined outward. The inclined surface portion 82 has areas configured in the order of an upper inclined surface 821, an upper vertical surface 824, an intermediate inclined surface 822, and a lower vertical surface 825 from above. A tapping hole 823 for attaching a D-shaped louver material (8D) to the mounting bracket 9, which will be described later, is provided inside the intermediate inclined surface 822. As shown in FIG.
As shown in FIG. 15, the mounting bracket 9 also functions as a support member 3 when used to form a unit by connecting the louver material D type (8D), which is a unit member of the louver, from the side. .
A vertical piece 88 extends upward and a hanging piece 81 extends downward continuously from the upper sloped surface 821 . The upper end 8a of the vertical piece 88 is provided with an upper horizontal piece 84 extending outward.
There is a space 83 surrounded by the upper sloped surface 821 , the upper vertical surface 824 and the hanging piece portion 81 . This space 83 is a place where the tips of screws 861 for attaching middle aggregates 86 (supporting members), which will be described later, are accommodated.

A plurality of D-shaped louver members (8D) are mounted vertically along the direction indicated by the dashed lines in FIG. 14 with mounting brackets 9 described in FIG. In the mounting mode of FIG. 14, the mounting interval of the louver material D type (8D) is the interval at which the upper louver material D type (8D) and the lower louver material D type (8D) overlap when viewed from the front. A ventilation opening 826 (longitudinal gap) leading to the inside is attached at intervals such that a ventilation opening 826 (vertical gap) leading to the inside is provided between the upper louver material D type (8D) and the lower louver material D type (8D) in a side view.

When viewed from the side, a lower gap 827 is formed between the upper louver material D type (8D) and the lower louver material D type (8D), and the wind blows from the outside toward the inside as indicated by the arrows. blow in. In addition, the inside cannot be seen from the outside, and the ventilation/blindfold part 22 has ventilation but the inside cannot be seen from the outside.
In Example 2, the lower end 8b of the upper D-shaped louver material (8D) and the upper end 8a of the lower D-shaped louver material (8D) overlap each other when viewed from the front. The installation interval is such that the width of the ventilation opening 826 (longitudinal gap) is maximized in the aspect of the portion 22 .
If it is desired to suppress ventilation, it is possible to narrow the width of the ventilation opening 826 (vertical gap) by narrowing the mounting interval (pitch).

[Holding portion of mounting bracket]
15A and 15B are explanatory diagrams for attaching the louver material D type (8D), FIG. 15A is an explanatory diagram for the louver panel body 2 and the mounting bracket 9, and FIG. 15(C) is a cross-sectional view along line AA in FIG. 15(A). Each sheet of D-shaped louver material (8D) is attached to the middle aggregate 86 and the mounting bracket 9 so as to form the louver panel body 2 with a predetermined interval. 3 can also be said. Thus, the support member 3 may also have other functions like the mounting bracket 9 .
The mounting bracket 9 may be attached at the time of construction on site, or may be attached at the factory.
The mounting bracket 9 can be fixed to an appropriate member of the scaffolding 7 under the elevated structure 5. In the second embodiment, H-shaped steel attached to the plate girder (lower elevated member) 51 via the auxiliary material 774 is used as the base material 95. A mode is adopted (see the enlarged view within the frame a in FIG. 4). In FIG. 15(B), the hatched mounting bracket 9 is an elongated bracket that serves as the side surface of the louver panel body 2 so that a plurality of D-shaped louver members (8D) can be attached in the vertical direction. . Moreover, the mounting bracket 9 has a holding portion 91 for holding the side of the D-shaped louver material (8D). The holding portion 91 is composed of three regions: a protruding portion 911 , a projection wall portion 913 and a contact portion 93 . The projected wall portion 913 of the holding portion 91 covers the side surface of the D-shaped louver material (8D), and has a tapping screw 912 that is driven from the projected wall portion 913 toward the side surface of the D-shaped louver material (8D). A tapping hole 823 is provided inside the inclined surface portion 82 of the D-shaped louver material (8D). By driving the tapping screw 912 from the projected wall portion 913 toward the tapping hole 823 of the D-shaped (8D) louver material, it is attached to the mounting bracket 9 .

When the louver panel bodies 2 using the mounting brackets 9 are arranged side by side and attached to the structure 1, the tapping screws 912 of the right and left louver panel bodies 2 face each other as shown in FIG. 15(A). It is preferably mounted so that it abuts against it. The tapping screws 912 at the same position face each other and abut against each other, thereby preventing loosening of the tapping screws 912 .

The contact portion 93 connected to the projection wall portion 913 may have a shape such as a projection or a ridge, and does not need to be a surface. The side wall (attached portion) is sandwiched between the contact portion 93 connected to the prospective wall portion 913 and the protruding portion 911 of the D-shaped louver (8D), so that the side wall of the D-shaped louver (8D) is held. When the louver material D type (8D) held by the side wall receives wind, a force is generated to rotate around the tapping screw 912, but the abutting part 93 sandwiching the louver material D type (8D) protrudes. Part 911 can resist that force.

When attaching the D-shaped louver material (8D) to the holding portion 91, any attachment means may be employed as appropriate. For example, a side wall (mounted portion) may be provided on the louver material D type (8D), and the side wall and the prospective wall portion 913 may be fastened with fasteners.

[Contact part of mounting bracket]
In FIG. 15B, the contact portion 93 and the groove portion 92 are shown enlarged. The mounting bracket 9 has a contact portion 93 connected to the projection wall portion 913 . The contact portion 93 may contact the vertical piece portion 88 of the D-shaped (8D) louver material, may contact the hanging piece portion 81, may contact only one side, or may contact both sides. may

[Groove part]
The mounting bracket 9 has a groove portion 92 adjacent to the contact portion 93 connected to the projection wall portion 913 . The groove portion 92 is for attaching the mounting bracket 9 to the base material 95 . One end of the groove portion 92 is a contact portion 93 connected to the holding portion 91 , and the other end is also a contact portion 93 . Since both sides of the groove portion 92 are contact portions 93, the rear surface of the D-shaped louver material (8D) is firmly supported. Note that the contact portion 93 at the other end is a planar contact surface in the second embodiment. However, the abutting portion 93 may be such that the end surface of the groove wall of the groove portion 92 directly abuts against the back surface of the D-shaped louver material (8D) and does not have a planar shape.

The groove portion 92 is provided for receiving a fastening member such as a bolt 923 for fixing the mounting bracket 9 to the base material 95 . Therefore, the depth of the groove portion 92 is such that at least the head of the bolt 923 can be accommodated therein.
A bottom portion 921 of the groove portion 92 abuts on the base material 95 and is provided with a bolt mounting hole 922 . The width of the groove portion 92 is approximately the same diameter as the head of the bolt 923 and functions as a detent for the bolt 923 .

[Backing material]
In the underpass scaffolding 7, the backing material 95 is fixed to the girder (underpass member) 51 or the like, and the louver material D type (8D) that becomes the louver panel body 2 is attached via the backing material 95. Since the base material 95 supports the louver panel body 2 which is exposed to the wind, it is preferable to use a high-strength material such as H-shaped steel.

[Middle aggregate]
FIG. 15(C) is a cross-sectional view along AA in FIG. 15(A). The section A-A is a section where the middle aggregate 86 (supporting member) lines a plurality of D-type louver materials (8D), and in the cross-sectional view it looks as if it is closed, but in reality it is. As shown in FIG. 15A, ventilation openings 826 (longitudinal gaps) are provided on both sides of the D-shaped louver material (8D) with the middle aggregate 86 (supporting member) interposed therebetween.
As described above, the D-shaped louver material (8D) is sandwiched from both sides between the holding portions 91 of the pair of mounting brackets 9 and attached to form the louver panel body 2 . Since the holding part 91 and the louver material D type (8D) are attached by driving the tapping screw 912 from the holding part 91 side, when exposed to strong wind, the force to rotate around the tapping screw 912 is generated. It takes. The D-type louver material (8D) attached to the mounting bracket 9 is held in the holding part 91 and therefore does not rotate easily. Alternatively, the tapping screw 912 may loosen even if it does not come off. In order to prevent this, a high-strength intermediate aggregate 86 (supporting member), which is a strip-shaped plate material, is attached. The middle aggregate 86 (supporting member) is preferably attached to the middle of the louver panel body 2 in the left-right width direction. The middle aggregate 86 (supporting member) vertically connects a plurality of attached louver material D-types (8D) and prevents individual louver material D-types (8D) from rotating.
As described above, the support member 3 is a member having the function of unitizing the louver material 4 to form the louver panel body 2 , and the central aggregate 86 also functions to unitize the louver material 4 , so the support member 3 can also be used. can.
As described above, the support member 3 may be the mounting bracket 9 or the intermediate aggregate 86, and may be of any shape, structure, mounting position, or the like.

[Fixation of middle aggregate]
The middle aggregate 86 (supporting member) is fixed with screws 861 to the hanging piece 81 of the louver material D type (8D).
A space 83 surrounded by the upper vertical surface 824, the upper inclined surface 821, and the hanging piece portion 81 shown in FIG. act as a place. The space 83 is located on the upper side of the inclined surface portion 82 of the D-shaped louver material (8D), and is a place that is not easily exposed to rain. Therefore, the space 83 protects the screw 861 and the screw hole into which the screw 861 is driven from corrosion. This prevents the middle aggregate 86 (supporting member), which is loaded with a force to rotate around the tapping screw 912, from coming off from the louver material D type (8D) due to corrosion of the screw 861 or the like.

[How to attach the louver panel body]
Assembling a large number of D-type (8D) louver materials on site is inefficient. In particular, as shown in FIG. 3, the scaffolding 7 under the elevated structure is narrow, so assembling a large number of D-shaped louver materials (8D) on site further deteriorates work efficiency. As shown in FIG. 15(A), by assembling the louver material D type (8D) and the mounting bracket 9 in advance to form the louver panel body 2, work efficiency can be improved. Further, by previously inserting the bolt 923 into the bolt mounting hole 922 in the bottom 921 of the groove 92 of the mounting bracket 9, the work efficiency at the site can be further improved. The mounting work of the louver panel body 2 is completed only by passing the bolts 923 attached to the louver panel body 2 in advance through the base material 95 and tightening them with separately prepared nuts 924 .
It should be noted that the mounting bracket 9 is not a special mounting member specialized for mounting a D-shaped (8D) louver material. The mounting bracket 9 can also be used to mount the louver panel body 2 of the louver material A type (4A) to the louver material C type (4C).

[Panel board]
FIG. 16 shows an attachment example of the closing portion 23 in which the louver material D type (8D) is attached to the panel plate portion 87. As shown in FIG. In the embodiment of FIG. 15(A), an intermediate aggregate 86 (supporting member) is used, and ventilation openings 826 (vertical gaps) are formed on both sides of the intermediate aggregate 86 (supporting member). In the embodiment of FIG. 16, instead of the middle aggregate 86 (supporting member), a panel plate portion 87 (supporting member) having substantially the same width as the D-type louver material (8D) is employed. The panel plate portion 87 (supporting member) completely covers the back surface of the D-shaped louver material (8D), and forms a closed portion 23 with no opening.
The embodiment of FIG. 16 is an example in which the panel plate portion 87 functions also as the support member 3, and is an example showing that the support member 3 may have any shape, structure, or the like.
The attachment of the louver panel body 2 using the panel plate portion 87 as the support member 3 to the base material 95 may be performed using the mounting bracket 9 described with reference to FIG. The plate portion 87 and the base material 95 may be attached by directly fastening.

(Example 3)
[Louver material E type]
FIG. 17 is an explanatory diagram of the louver material E type (8E). Compared with the louver panel body 2 of the louver material D type (8D) of FIG. The first feature is that they are connected and integrally molded. Therefore, in the E-type louver material (8E), the panel plate portion 87 functions as the support member 3, and the E-type louver material (8E) itself serves as the louver panel body 2.
At the uppermost end of the panel plate portion 87, only one upper lateral piece portion 84 extending outward is formed.
Since the louver material E type (8E) is in a mode that serves only as the closing part 23, the upper end 8a of the louver material E type (8E) does not need anything other than the upper horizontal piece 84 from a functional point of view and is strong in appearance. It is omitted because it does not give an impression.
Further, the louver material E type (8E) does not have the tapping holes 823 on the back surface of all the inclined surface portions 82 .
As described above, the louver material E type (8E) of Example 3 leaves the minimum necessary members for function and appearance, and combined with integral molding, cost reduction can be achieved.

For the sake of explanation, in FIG. 17, the appearance of the louver material E type (8E) is made to resemble the louver material D type (8D), but the appearance of the louver material E type (8E) is similar to that of the louver material A type (4A). ~Louver material C type (4C) may be similar to any type. When the louver material type A (4A) to the louver material type C (4C) are viewed individually, the impression of the appearance is different. In particular, the louver material type C (4C) having a long vertical piece 42 is clearly different from the louver material type A (4A) and the louver material type B (4B). However, if the louver panel body 2 is used, the shape of the inclined surface portion 41 gives a strong impression, and the vertical piece portion 42 may be swallowed by the inclined surface portion 41 of the louver material 4 attached to the upper part, and the installation interval may be reduced. It is perceived only as a difference, and its contribution to appearance decreases. In addition, since the lower horizontal piece 43 is difficult to see in the first place, its contribution to the appearance is low. Furthermore, the inside of the louver material 4 is darker than the outside, and even if there is a lighting opening 213, the difference in brightness from the blocking part 23 is not so noticeable. Therefore, it is difficult to distinguish any type of louver material 4 except for the mounting interval. Therefore, louver material E type (8E) imitating any one of louver material type A (4A) to louver material C type (4C) is prepared, and louver material type A (4A) to louver material type C ( 4C), even if it is arranged side by side with the louver panel body 2 composed of 4C), since the positions of the inclined surface portions 41 are aligned, the external appearance is substantially the same.
In preparation for changing the mounting interval of the louver members 4, it is preferable to prepare the louver member E type (8E) in which the mounting intervals of the inclined surface portions 82 are changed.

[How to attach the louver material E type to the base material]
FIG. 18 is an explanatory view of attaching the louver material E type (8E) to the base material 95. As shown in FIG.
Using the mounting bracket 9 of the second embodiment, it is mounted in the same procedure. A different point is that the tapping holes 823 of the louver material E type (8E) do not exist inside all the inclined surface portions 82 but exist every other one. Therefore, work efficiency during installation work is improved.
The tapping hole 823 and the mounting bracket 9 are fastened with a tapping screw 912 and fixed so as to hold the louver material E type (8E) from the side.

[Installation interval of louver material E type]
FIG. 19 is an explanatory diagram of the installation interval (pitch) of the E type louver material (8E).
The figure shows a state in which two louver materials E type (8E) are attached to a base material 95 indicated by a chain line. In Example 3, when the upper louver material E type (8E) and the lower louver material E type (8E) are attached so that the appearance of the large number of inclined surface portions 82 are arranged at regular intervals, the thermal elongation margin 89 (vertical The positions of the panel plate portion lower end 871 of the upper louver material E type (8E) and the upper lateral piece portion 84 (upper end 8a) of the lower louver material E type (8E) are set so that a gap is formed. . The thermal elongation margin 89 (longitudinal gap) is a gap provided for thermal elongation in the vertical direction of the louver material E (8E) exposed to high temperatures in summer. The lower end 871 of the panel plate portion and the upper horizontal piece portion 84 (upper end 8a) of the louver material E type (8E) located below are prevented from coming into contact with each other. Of course, the upper and lower louver material E type (8E) may be arranged so as to be spaced apart further to form the ventilation opening 826 (longitudinal gap).

At this time, the upper horizontal piece portion 84 is located between the lower end 871 of the panel plate portion of the louver material E type (8E) located above in side view and the upper horizontal piece portion 84 of the louver material E type (8E) located therebelow. limit the length of the width of the thermal elongation margin 89 (vertical gap) or the ventilation opening 826 (vertical gap).

Further, although not shown, in the case of a louver material E type (8E) imitating the louver material A type (4A) to the louver material type C (8C) as in Example 1, the louver material E type (8E) At the lower end 8b of the inclined surface portion 82 at the lowest end of the lower horizontal piece portion 43 present in the functionally important louver material A type (4A) to louver material C type (8C) may be provided.
The lower horizontal piece 43 of the louver panel body 2 of the louver material A type (4A) to the louver material E type (8E) imitating the louver material C type (8C) is the lower part of the louver panel body 2 that is above in side view. It limits the length of the width of the lower gap 827 formed between the horizontal piece 43 and the upper end 8a (upper horizontal piece 84) of the louver panel body 2 located therebelow.
In the present invention, the lower horizontal piece 43 may be attached to the lower end 8b of the lowermost sloped surface 82 of the E-shaped louver material (8E), if necessary.

[Uniformity of Appearance]
20A and 20B are explanatory diagrams of how to properly use the D type louver material (8D) and the E type louver material (8E). is.
A D-shaped louver material (8D) is attached to the upper part of FIG. play. The installation interval (pitch) of the D-type (8D) louver material on the upper part is installed at an interval corresponding to the ventilation/blinding part 22 .
On the other hand, a louver material E type (8E) is attached to the lower part.
The upper louver panel body 2 made of D-type louver material (8D) serves as a ventilation/blinding portion 21, while the lower louver panel body 2 made of E-type louver material (8E) serves as a blocking portion 23. and are used properly.
The louver panel body 2 made of the upper louver material D type (8D) and the lower louver panel body 2 made of the lower louver material E type (8E) have the same shape of the inclined surface portion 82 which gives a strong impression to the appearance. In the louver material E type (8E), some members (the upper horizontal piece 84, the tapping hole 823, etc.) that contribute less to the appearance are partially omitted, but they are indistinguishable at first glance. Even if the louver panel body 2 made of the louver material D type (8D) and the louver panel body 2 made of the louver material E type (8E) are used side by side, the appearance with a sense of unity can be obtained.

FIG. 20(B) is an explanatory diagram of the left and right louver panel bodies 2 used separately. The right part is formed by attaching two louver material E type (8E) to the base material 95 with the mounting metal fittings 9, forming the closing part 23. As shown in FIG. Once the right and left louver panel bodies 2 are attached to the backing material 95 via the mounting brackets 9, even if the louver material 4 is of a different type, the left and right parts look the same and cannot be distinguished from each other. Gone.

As described above, it is possible to meet the requirements of the location of the structure 1 where the louver panel body 2 is to be installed, for example, the requirement for the ventilation/blinding section 22 here and the blocking section 23 here. The louver panel body 2 of the louver material D type (8D) and the louver material E type (8E) are very similar in appearance, and do not impair the uniformity of the design while meeting the requirements.

The specific configuration is not limited to these embodiments, and the present invention includes any modification of design without departing from the gist of the present invention.

In addition, the above-described embodiments and various aspects can be combined by diverting each other's techniques as long as there is no particular contradiction or problem in the purpose, configuration, or the like.
