  2. Description of the Related Art Conventionally, in a window frame sash or the like, a joining structure in which an end surface of a horizontal frame is fastened and fixed to a joining surface of a vertical frame via a sealing material (see Patent Document 1).

  In Patent Document 1, a convex portion surrounding the mounting hole portion formed in the joining surface of the vertical frame is formed by press molding or the like, and the protrusion for preventing collapse of the sealing material by the butting between the convex portion and the end surface of the horizontal frame is provided as a convex portion. Is held for the height of.

Japanese Utility Model Publication No. 57-174681

However, in patent document 1, since the convex part is formed in the circumference | surroundings of the attachment hole part, a convex part contact | abuts to the end surface of the screw holding (screw hole part) of a horizontal frame. Accordingly, it is impossible to dispose a sealing material at a portion of the horizontal frame where the convex portion abuts.
For this reason, as shown in FIG. 2 of Patent Document 1, in the plate portion of the lower frame (the flat plate portion formed between the inner and outer rail base ends), the sealing material cannot be disposed at the base end portion of the screw hole portion.
And the metal touch part which the contact surface of a vertical frame and the end surface of a lower frame contact directly cannot ensure a water stop performance, since the sealing material is not interposed. Therefore, also in patent document 1, the base end part of the screw hole part which cannot arrange | position a sealing material cannot ensure water stop performance. For this reason, in the junction part of a vertical frame and a lower frame, the water stop line formed with the said sealing material cannot be continued from the outdoor side to the indoor side, and water stop performance falls. Therefore, there has been a problem that water enters the housing side from the bishole base end where the water stop line is interrupted.

  An object of the present invention is to provide a joint structure and a joiner for a shape member capable of improving water-stopping performance at the joint portion of the shape member.

The first profile joining structure of the present invention is a profile junction structure in which the longitudinal end face of the first profile is joined to the joint face of the second profile, and the end face of the first profile. A sheet-like sealing material is interposed between the joint surfaces of the second profile and a water stop line forming portion is formed on the end surface of the first profile, and the water stop line forming portion and the second profile are formed. By sandwiching the sealing material with the joint surface, a water stop line continuous in the prospective direction is formed, and one of the first profile and the second profile has the position different from the water stop line. A gap forming means for setting the gap dimension between the first profile and the second profile to a predetermined dimension in contact with the other of the first profile and the second profile is provided , and the first profile has a screw hole portion. And a screw hole into which a screw to be screwed into the screw hole portion of the first shape member is inserted in the joint surface of the second shape member The gap forming means is formed by a protruding portion formed by extrusion processing on the second shape member, and the protrusion portion is a shape member end surface other than the screw hole portion of the first shape member, and Further, it is abutted at a position different from the water stop line forming portion .

Here, as the first shape member and the second shape member, any members that are joined to each other may be used, but in particular, frame materials (window frames) used for various fittings that require water stoppage (waterproofing). Examples include frame materials and shoji screens. For example, as the joinery, various joinery such as a window, an entrance door, a doorway door, and a bathroom door in a building can be exemplified.
When a horizontal frame (upper frame or lower frame) is placed between a pair of vertical frames as a fitting, the left and right end surfaces of the horizontal frame are joined to the side surfaces (joint surfaces) of the vertical frame. Is the first profile and the vertical frame is the second profile. On the other hand, as a fitting, when placing a vertical frame between a pair of horizontal frames (upper frame, lower frame), the upper and lower end surfaces of the vertical frame are joined to the lower surface and upper surface (joint surface) of the horizontal frame, The vertical frame is the first profile and the horizontal frame is the second profile.

According to the present invention described above, when the end surface of the first shape member and the joint surface of the second shape member are joined, the water stop line continuous in the prospective direction is formed with the sheet-like sealing material interposed. This water stop line is formed along the water stop line forming part formed on the end face of the first profile. That is, the first profile is formed into a long member having a predetermined cross-sectional shape by extrusion molding. Therefore, the end face of the first profile is provided with a meat portion such as a fin or a connecting portion corresponding to the cross-sectional shape. And in the meat part of the end surface of this 1st profile, the part which continues in the prospective direction of a 1st profile is made into a water stop line formation part, Between this water stop line formation part and the joint surface of a 2nd profile If a sealing material is arrange | positioned in this, a sealing material will be pinched | interposed and compressed by the joint surface of the water stop line formation part of a 1st profile end surface, and a 2nd profile. The compressed portion of the seal material, that is, the portion that contacts the water stop line forming portion ensures water stop performance, and thus functions as a water stop line at the joint between the first shape member and the second shape member.
Then, one of the first profile and the second profile abuts the other of the first profile and the second profile at a position different from the water stop line, that is, a position not overlapping the water stop line. A gap forming means is provided. For example, when the gap forming means is provided in the second profile, the gap forming means is brought into contact with the end face of the first profile at a position different from the water stop line forming portion. On the other hand, when the gap forming means is provided in the first profile, the gap forming means is provided at a position different from the water stop line forming portion of the first profile, and this gap forming means is brought into contact with the joint surface of the second profile. I am letting.
As described above, the gap forming means provided at a position different from the water stop line in one of the first shape member and the second shape member is brought into contact with the other, so that the first shape member and the second member are formed in the water stop line portion. A gap of a predetermined dimension can be formed between the shape members.

  In addition, the said water stop line is formed in the position which needs to prevent permeation of water in the junction part of a 1st profile and a 2nd profile. For example, the first profile is the lower frame of the window frame fixed to the building frame (wall) of the building, the second profile is the vertical frame, and water is located on the frame side, that is, below the upper surface of the lower frame. In order to prevent intrusion, a water stop line may be formed along the end surface of the upper surface portion of the lower frame. Moreover, what is necessary is just to form a water stop line along the lower surface of a drainage path, when a hollow part is formed in the back side of the upper surface part of a lower frame, and this hollow part is utilized as a drainage path.

In addition, when joining the first shape member and the second shape member in a factory or the like, the gap forming means is brought into direct contact with the other of the first shape member and the second shape member. Therefore, there is no possibility of generating a portion where the seal is cut and the sealing performance of the sealing material is not deteriorated due to insufficient compression. For this reason, the workability | operativity at the time of joining of each shape material can be improved.
Furthermore, when the joinery assembled by joining the first shape member and the second shape member is transported to the construction site or the like and applied, stress is applied to the joint portion of the shape member. Since the gap dimension between each shape member in the water stop line is maintained, the sealing material is not crushed and damaged. For this reason, the sealing performance of each shape material joining part is not deteriorated at the time of transportation and construction.
In addition, after construction of the joinery, deterioration of the sealing material can be prevented even if thermal expansion of the first profile occurs repeatedly. For example, when the first profile is exposed to direct sunlight, the surface temperature of the first profile rises, and the first profile expands due to the heat. On the other hand, when the temperature of the first profile decreases at night, the first profile returns to its original length. For this reason, the first profile repeats thermal expansion every day. When only the sealing material is interposed between the first shape material and the second shape material, if the first shape material is thermally expanded, stress is applied to the sealing material and the material is crushed. For this reason, if the thermal expansion of the shape material is repeated for many years, a stress is repeatedly applied to the sealing material, the sealing material is deteriorated and the water stop performance is lowered, and therefore maintenance is required in a short period of time.
On the other hand, according to the present invention, since the gap forming means is provided, the gap between the first profile and the second profile is maintained constant even when the first profile repeats thermal expansion. Without being crushed, it is possible to prevent the sealing material from being deteriorated and the water stop performance from being lowered.

In addition, since the gap forming means is constituted by the protrusions formed by the extrusion process in the second profile, if the mold for forming the screw holes and the projections is prepared, the second profile is pressed. The protrusion can be formed simultaneously with the screw hole. Therefore, the gap forming means can be formed easily and inexpensively.
In addition, since the protrusions formed on the second shape member are in contact with the positions other than the screw hole portion and different from the water stop line formation portion, the gap size between the shape members is set, so that gap formation The degree of freedom of the formation position of the protrusions as means increases, and the protrusions can be formed at positions suitable for forming gaps between the respective shape members. That is, in order to join each shape member with a required strength, the position where the screw hole portion is formed is limited depending on the size and shape of each shape member. For this reason, if the protrusion is brought into contact with the screw hole portion, it may not necessarily be an optimal place for forming a gap between the first shape member and the second shape member.
On the other hand, in the present invention, on the end face of the first shape member, the projection can be brought into contact at a free position other than the screw hole part and other than the water stop line forming part. The gap forming means can be arranged at a different place.

The joining structure of the 2nd shape member of this invention is a joining structure of the shape member which joins the end surface of the longitudinal direction of a 1st shape member to the joining surface of a 2nd shape material, Comprising: The end surface of the said 1st shape member A sheet-like sealing material is interposed between the joint surfaces of the second profile and a water stop line forming portion is formed on the end surface of the first profile, and the water stop line forming portion and the second profile are formed. By sandwiching the sealing material with the joint surface, a water stop line continuous in the prospective direction is formed, and one of the first profile and the second profile has the position different from the water stop line. A gap forming means is provided in contact with the other of the first profile and the second profile to set a gap between the first profile and the second profile to a predetermined dimension, and the first profile and the second profile are provided. The material includes a nail fin portion, and the gap forming means is formed on the side surface of the second shape member by a protruding process, and the first shape It is preferred that the nail fin portion is constituted by a protrusion abutting the profile end faces in until the outdoor surface.

Here, a nail fin part is a fin part used in order to fix each shape material to a housing with a bis | screw etc. FIG. Usually, in each profile, the position of the nail fin portion in the prospective direction matches.
According to such a configuration, it is possible to effectively prevent stress from being applied to the sealing material due to the thermal expansion of the first profile. In other words, the thermal expansion of the first profile is mainly due to a temperature increase due to direct sunlight. Therefore, in the first shape member, the amount of thermal expansion increases as the surface of the outdoor side irradiated with direct sunlight increases. In particular, since the first profile is fixed to the housing at the nail fin portion, the outdoor side of the first profile is more likely to thermally expand than the nail fin portion.
Therefore, in the present invention, the protrusion formed on the second shape member is in contact with the nail fin portion of the first shape member or the shape portion outside the nail fin portion. Thus, even if the outdoor side of the first shape member is thermally expanded, the protrusion can reliably maintain a gap with the second shape member, and the seal material can be prevented from being excessively crushed. Therefore, the present invention is suitable for joining shape members provided at a position irradiated with direct sunlight such as a building window.

The third profile joining structure of the present invention is a profile joining structure in which the longitudinal end face of the first profile is joined to the joint face of the second profile, and the end face of the first profile.

A gap forming means for setting the gap dimension between the first profile and the second profile to a predetermined dimension in contact with the other of the first profile and the second profile is provided . A component mounting fin for mounting the component is formed on the surface of the profile, and the gap forming means protrudes from a side surface of the second profile. It is preferably constituted by a protrusion processed is formed by abutting to the component mounting fins.
Here, various parts such as a windshield plate and a crescent stopper can be exemplified as the parts attached by the part mounting fins.

According to such a configuration, the protrusions formed on the second shape member are brought into contact with the end face of the component mounting fin to set the gap size between the shape members. A gap can be formed using the formed part mounting fins. For this reason, it is not necessary to perform special processing on the first shape member, and a gap can be formed only by newly processing a projection as gap formation means on the second shape member, thereby reducing the cost.
Furthermore, since the component mounting fin is formed on the surface side of the first profile, it is determined whether the protrusion is in contact with the component mounting fin when the first profile and the second profile are joined. It is easy to check and the gap size can be set reliably.

The fourth profile joining structure of the present invention is a profile joining structure in which the end face in the longitudinal direction of the first profile is joined to the joint face of the second profile, and the end face of the first profile. A sheet-like sealing material is interposed between the joint surfaces of the second profile and a water stop line forming portion is formed on the end surface of the first profile, and the water stop line forming portion and the second profile are formed. By sandwiching the sealing material with the joint surface, a water stop line continuous in the prospective direction is formed, and one of the first profile and the second profile has the position different from the water stop line. A gap forming means is provided in contact with the other of the first profile and the second profile to set the gap dimension between the first profile and the second profile to a predetermined dimension .

  According to such a configuration, the projections formed on the second profile are brought into contact with the end surfaces of the contact fins formed on the first profile, so that the gap dimension between the profiles is set. The contact fin can be formed at a position most suitable for forming a gap. For this reason, it is necessary to form a new contact fin on the first profile, but the protrusion can be brought into contact with the most suitable place for gap formation, and a predetermined gap dimension can be set reliably, In addition, the setting work, that is, the joining work of each shape member can be made more efficient.

The fifth shape joining structure of the present invention is a shape joining structure in which the end face in the longitudinal direction of the first shape is joined to the joining face of the second shape, and the end face of the first shape. A sheet-like sealing material is interposed between the joint surfaces of the second profile and a water stop line forming portion is formed on the end surface of the first profile, and the water stop line forming portion and the second profile are formed. By sandwiching the sealing material with the joint surface, a water stop line continuous in the prospective direction is formed, and one of the first profile and the second profile has the position different from the water stop line.

An angle member 30 made of resin is attached to the attachment portion 37 so as to be continuous with the angle member 20 and hide the gap between the casing and the vertical frame 3.

The housing fixing portion 36 includes a nail fin portion 361 and a housing abutting portion 362. The nail fin portion 361 is formed on the side surface portion 34 so as to protrude from the position in the same prospective direction as the nail fin portion 261 toward the outside of the window frame 1. The nail fin portion 361 is arranged along the outdoor side of the housing, and the vertical frame 3 is fixed to the outer surface of the housing chamber by screwing a screw 363 (see FIG. 6) from the outdoor side to the housing through the nail fin portion 361. Is done.
The housing contact portion 362 is formed so as to protrude from the indoor side end portion of the side surface portion 34 toward the outside of the window frame 1. The front end of the housing contact portion 362 is in contact with the side surface of the housing.
Then, the vertical frame 3 is fixed to the side surface of the housing by screwing a screw 364 (see FIG. 6) from the inner surface of the side surface portion 34 to the housing between the rail drawing portion 31 and the housing contact portion 362. The

As shown in FIG. 2, screw holes 341 and 342 are formed at positions corresponding to the first and second screw hole portions 28 and 29 of the lower frame 2 on the joint surface of the side surface portion 34.
In addition, a protrusion 346 is formed on the joint surface of the side surface 34. The protruding portion 346 is formed at a position where it comes into contact with the end face of the component mounting fin 248.

  Here, the screw holes 341 and 342 and the protrusion 346 are formed by press working using a mold. That is, the screw holes 341 and 342 are formed in the vertical frame 3 by punching, and the protrusions 346 are formed by extrusion. The screw holes 341 and 342 and the protruding portion 346 can be processed simultaneously by forming a punched portion and a protruding portion in a press mold.

[Configuration of sealing material]
The sealing material 4 is a sealing material (sealer) made of sheet-like butyl rubber or the like. As shown in FIGS. 2 and 4, the sealing material 4 is formed in a shape matching the end face shape of the lower frame 2.
That is, the upper surface side of the sealing material 4 is the shape of the upper surface of the lower frame 2, specifically, the first surface portion 241, the first upright portion 245, the second surface portion 242, the second upright portion 246, and the third upright portion 247. The third surface portion 243 and the attachment portion 27 are shaped.
Further, the lower surface side of the sealing material 4 has a lower surface shape of the lower frame 2, specifically, a shape along the first lower surface portion 252, the nail fin portion 261, the connecting portion 253, the second lower surface portion 254, and the connecting portion 255. Has been. For this reason, the opening end surfaces of the first hollow portion 250A and the second hollow portion 250B are closed by the sealing material 4 except for the screw hole portions 28 and 29.

  Holes 411 and 421 are formed in the sealing material 4 at positions corresponding to the screw holes 341 and 342 of the vertical frame 3. Each of the hole portions 411 and 421 is a hole that is formed to have substantially the same size as the screw holes 341 and 342 and through which the screw 45 is inserted.

As shown in FIG. 5A, the thickness dimension of the sealing material 4 is larger than the projecting dimension of the projecting portion 346 of the vertical frame 3, that is, the projecting dimension from the surface of the side surface portion 34. For example, when the protruding dimension of the protrusion 346 is 0.5 mm, the thickness dimension of the sealing material 4 is set to 1.0 mm or the like.
5A and 5B are vertical cross-sectional views of the lower frame 2 and the vertical frame 3, and are vertical cross-sectional views in which the expected direction is the position of the protrusion 346. FIG. On the other hand, FIG. 6 is a plan sectional view of the vertical frame 3 cut at a position above the protrusion 346.

  On the other hand, as shown in FIG. 5B and FIG. 6, the screw 45 for joining is inserted into the screw holes 341 and 342 of the side surface portion 34, and the screw hole portions 28, When screwed into 29, the vertical frame 3 and the lower frame 2 are pulled toward each other to a position where the projection 346 of the side surface portion 34 and the end surface of the component mounting fin 248 come into contact with each other. For this reason, the sealing material 4 is compressed by the side surface portion 34 and the end surface of the lower frame 2. As described above, when the protruding dimension of the protrusion 346 is 0.5 mm and the thickness dimension of the sealing material 4 is 1.0 mm, the sealing material 4 is compressed to 0.5 mm, that is, the compression rate is 50%. .

As described above, when the lower frame 2 and the vertical frame 3 are joined with the screw 45 via the sealing material 4, the base end of the draining piece portion 251, the first surface portion 241, and the first screw hole portion 28 in the sealing material 4. Portion, first upright portion 245, second surface portion 242, second upright portion 246, third upright portion 247, third surface portion 243 (base end portion of second screw hole portion 29), and position to contact attachment portion 27 However, it functions as a water stop line that is compressed at a predetermined compression rate (for example, 50%) to ensure water stoppage between the lower frame 2 and the vertical frame 3. Accordingly, in the lower frame 2, the draining piece portion 251, the first surface portion 241, the base end portion of the first screw hole portion 28, the first upright portion 245, the second surface portion 242, the second upright portion 246, and the third upright portion. The water stop line forming part 240 is configured by the second surface part 247, the third surface part 243 (the base end part of the second screw hole part 29), and the end face part of the attachment part 27. In addition, in this embodiment, since the water stop line should just be continuously formed from the outdoor surface of the lower frame 2 to an indoor surface, it is not necessary to make the drain piece part 251 whole into the water stop line formation part 240. Only the portion of the draining piece portion 251 that is continuous to the outdoor side of the first surface portion 241 (the thickness of the draining piece portion 251) may be used as the water stop line forming portion 240.
In addition, the base end part of the 1st screw hole part 28 which comprises the water stop line formation part 240 is a part which connects the 1st surface part 241 and the 1st standing part 245, and protrudes in circular arc shape from this connection part. The two arc portions are not included in the water stop line forming portion 240. Similarly, the base end portion of the second screw hole portion 29 constituting the water stop line forming portion 240 is a portion of the third surface portion 243, and the two arc portions protruding in an arc shape from the third surface portion 243 are It is not included in the water stop line forming part 240.
Therefore, the contact part (metal touch part) of the protrusion 346 and the component mounting fin 248 is formed at a position different from the water stop line forming part 240, specifically, a position shifted from the water stop line. Yes. For this reason, the said metal touch part does not overlap with a water stop line, and the water stop line is continuously formed in the junction part of the lower frame 2 and the vertical frame 3 from the outdoor side of a prospective direction to the indoor side.
Since this water stop line is provided, even if rainwater flows from the upper surface of the lower frame 2 or the side surface 34 of the vertical frame 3 to the water stop line, the lower side of the water stop line, for example, the screw holes 28 and 29 and the hollow portion. Rainwater does not enter 250A and 250B.

  Further, in the hollow portions 250A and 250B, the seal material 4 also has a predetermined position in contact with the first lower surface portion 252, the connecting portion 253, the nail fin portion 261, the second lower surface portion 254, and the connecting portion 255. Therefore, it functions as a second water stop line.

[Joint structure of upper frame and vertical frame]
Since the joining structure of the vertical frame 3 and the upper frame 5 is the same as the joining structure of the lower frame 2 and the vertical frame 3, it will be briefly described.
As shown in FIG. 3, the upper frame 5 includes an outer rail portion 51, an inner rail portion 52, a screen door rail portion 53, a front surface portion 54, a back surface portion 55, a housing fixing portion 56, a mounting portion 57, a first screw hole portion 58, A second screw hole portion 59 is provided. The formation positions of the screw holes 58 and 59 are similar to the screw holes 28 and 29 of the lower frame 2, and a water stop line in the upper frame 5 described later is formed in circular regions 581 and 591 coaxial with the centers of the screw holes 58 and 59. It is set to be included.

  The surface portion 54 is a portion exposed on the surface (lower surface) of the upper frame 5. Therefore, the surface portion 54 is substantially along the direction in which the first frame portion 541, the second surface portion 542, and the third surface portion 543 formed along the prospective direction of the upper frame 5 and the upper frame 5 is found. A first raised portion 545, a second raised portion 546, and a third raised portion 547 are formed.

The first surface portion 541 is formed between the upper end of the screen door rail portion 53 and the first screw hole portion 58. The first screw hole portion 58 and the upper end of the outer rail portion 51 are connected by a first upright portion 545.
The second surface portion 542 is formed between the upper end of the second raised portion 546 and the upper end of the third raised portion 547. The third upright portion 547 is formed at a position on the outdoor side of the inner rail portion 52, and a component mounting fin 548 is provided projecting toward the outdoor side at the lower end thereof.

The third surface portion 543 is formed between the inner rail portion 52 and the attachment portion 57. The second screw hole portion 59 is formed at a joint portion of the third upright portion 547, the inner rail portion 52, and the third surface portion 543.
The attachment portion 57 is formed from the indoor side end portion of the third surface portion 543 toward the finding direction (downward direction). A resin angle member 50 is attached to the interior surface of the attachment portion 57.

The back surface portion 55 is a portion disposed on the back surface side, that is, above the top surface portion 54 in the upper frame 5. For this reason, the back surface portion 55 includes a first upper surface portion 552 and a connecting portion 553.
The first upper surface portion 552 is formed from the position where the first screw hole portion 58 of the first surface portion 541 is formed toward the indoor side.
The connecting portion 553 is formed to extend downward from the lower surface of the first upper surface portion 552 and is connected to the second surface portion 542.

The housing fixing portion 56 includes a nail fin portion 561 and a housing abutting portion 562.
The nail fin portion 561 is formed upward from the indoor side end portion of the first upper surface portion 552. The nail fin portion 561 is disposed along the outdoor side of the housing, and a screw (not shown) is screwed from the outdoor side to the housing through the nail fin portion 561 to fix the upper frame 5 to the outdoor surface of the housing. .
The housing contact portion 562 is formed upward from the indoor side end of the third surface portion 543. The front end of the housing contact portion 562 is in contact with the lower surface of the housing.
The upper frame 5 is fixed to the lower surface of the housing by screwing a screw (not shown) from the third surface portion 543 to the housing between the inner rail portion 52 and the housing contact portion 562 in the prospective direction.

Screw holes 351 and 352 are formed at positions corresponding to the screw holes 58 and 59 at the upper end of the side surface 34 of the vertical frame 3, respectively. Therefore, a joint surface to which the upper frame 5 is joined is formed at the upper end portion of the side surface portion 34 of the vertical frame 3.
In addition, a protrusion 356 is formed on the side surface portion 34. The projecting portion 356 is provided at a position corresponding to the component mounting fin 548.

Here, the screw holes 351 and 352 and the protrusion 356 are simultaneously formed by punching and extrusion using a mold.
Further, the sealing material (not shown) disposed between the vertical frame 3 and the upper frame 5 is formed with a hole through which a joining screw is inserted, as in the sealing material 4.

Therefore, when the vertical frame 3 and the upper frame 5 are joined with screws with the sealing material interposed therebetween, the projections 356 and the end surfaces of the component mounting fins 548 come into contact with each other, and the sealing material between the upper frame 5 and the vertical frame 3 is compressed. The Accordingly, in the sealing material, the upper surface portion of the upper frame 5, specifically, the screen door rail portion 53, the first surface portion 541, the base end portion of the first screw hole portion 58, the first upper surface portion 552, the nail fin portion 561, A water stop line is formed at a position where the connecting portion 553, the second surface portion 542, the third upright portion 547, the base end portion of the second screw hole portion 59, the third surface portion 543, and the attachment portion 57 abut. Therefore, in the upper frame 5, the screen door rail 53, the first surface portion 541, the base end portion of the first screw hole portion 58, the first upper surface portion 552, the nail fin portion 561, the connecting portion 553, the second surface portion 542, The three standing upper parts 547, the base end part of the second screw hole part 59, the third surface part 543, and the end face part of the attachment part 57 constitute a water stop line forming part. In addition, since the water stop line should just be continuously formed from the outdoor surface of the upper frame 5 to the indoor surface, the entire screen door rail portion 53 does not need to be a water stop line. Only the portion that continues to the outdoor side of the one surface portion 541 may be a water stop line.
In addition, the base end part of the 1st screw hole part 58 which comprises a water stop line formation part is a part which connects the 1st surface part 541 and the 1st upper surface part 552, and the circular arc which protrudes in circular arc shape from this connection part The portion that is continuous with the first rising portion 545 is not included in the water stop line forming portion. Similarly, the base end portion of the second screw hole portion 59 constituting the water stop line forming portion is a part of the third upright portion 547 and the third surface portion 543, and protrudes in an arc shape from the third surface portion 543. The arc portion and the portion protruding in an arc shape from the third upright portion 547 are not included in the water stop line forming portion.
This water stop line prevents rainwater falling on the upper surface of the upper frame 5 from entering the joint between the vertical frame 3 and the upper frame 5.

According to this embodiment, there are the following effects.
(1) Since the projections 346 and 356 as gap forming means are provided on the vertical frame 3 of the window frame 1, the projections are formed when the lower frame 2 or the upper frame 5 and the vertical frame 3 are joined with the screws 45. The gaps between the lower frame 2 and the upper frame 5 and the vertical frame 3 can be set to a predetermined size by bringing the parts 346 and 356 into contact (metal touch) with the component mounting fins 248 and 548. Therefore, when the lower frame 2 or the upper frame 5 as the first shape member and the vertical frame 3 as the second shape member are joined with the seal material 4 interposed therebetween, the compression dimension of the seal material 4, that is, the compression rate is set. It can be set to a predetermined value, and the required water stop performance can be obtained with certainty.
Further, when the window frame 1 is assembled by joining the vertical frame 3, the lower frame 2, and the upper frame 5, the projecting portions 346 and 356 are brought into contact with the end surfaces of the component mounting fins 248 and 548, so that the seal The material 4 is not crushed more than necessary to generate a portion where the seal is broken, and conversely, the sealing performance of the sealing material 4 is not deteriorated because the material is not sufficiently compressed. For this reason, the workability | operativity at the time of the assembly of the window frame 1 can be improved.
In addition, when the window frame 1 is assembled and then transported to the site or the like, when the stress is applied to the joining portion of the vertical frame 3 and the lower frame 2 or the upper frame 5, the projections 346 and 356 The clearance dimension between the vertical frame 3, the lower frame 2, and the upper frame 5 in the water stop line can be maintained. For this reason, the sealing material 4 is not crushed and damaged, and the sealing performance of the shape joint portion is not deteriorated during transportation and construction.
Furthermore, even if the lower frame 2 and the upper frame 5 are thermally expanded by direct sunlight, the sealing material 4 is not excessively compressed because the protrusions 346 and 356 serving as the gap forming means are provided. For this reason, even if the thermal expansion of the lower frame 2 and the like is repeated after the construction of the window frame 1, the deterioration of the sealing material can be suppressed, and the period until the sealing material 4 is maintained can be lengthened.

(2) Since the contact portions of the protrusions 346 and 356 and the component mounting fins 248 and 548 that are gap forming means are formed at positions different from the water stop line, the water stop line is formed in the vertical frame 3 and the lower frame 2. It can form continuously in a prospective direction in the joint part of, and water stop performance can be secured.
In addition, since the protrusions 346 and 356 are formed on the surface side of the lower frame 2 and the upper frame 5 with respect to the water stop line (the side opposite to the building housing side), the protrusions 346 and 356 are formed on the window frame 1. It is exposed on the surface (inner peripheral surface). For this reason, when the lower frame 2 or the upper frame 5 and the vertical frame 3 are joined, the protrusions 346 and 356 are in contact with the component mounting fins 248 and 548, and it is possible to work reliably while visually confirming whether a clearance is secured. it can.
Further, the contact portions of the protrusions 346 and 356 and the component mounting fins 248 and 548 are positions on the surface side of the water stop line where the sealing material 4 is disposed, and are formed at positions different from the sealing material 4. Therefore, it is not necessary to process holes and grooves for arranging the protrusions 346 and 356 in the sealing material 4. For this reason, the processing work of the sealing material 4 can be reduced, and the manufacturing cost can also be reduced.

(3) Since the protrusions 346 and 356, which are gap forming means, are formed in the vertical frame 3 by extrusion, they can be processed simultaneously with the punching of the screw holes 341, 342, 351, and 352. Therefore, the number of man-hours for machining is not different from that when only the screw holes 341, 342, 351, 352 are machined, so that the protrusions 346, 356 can be easily formed without increasing the cost.
Furthermore, since the protrusions 346 and 356 are formed at positions where they abut against the component mounting fins 248 and 548, it is not necessary to add a special configuration for forming a gap in the lower frame 2 and the upper frame 5. For this reason, it is only necessary to form the protrusions 346 and 356 in the vertical frame 3, and the lower frame 2 and the upper frame 5 can be formed in the same frame shape as before, so that the cost for configuring the gap forming means can also be reduced.

(4) Since the component mounting fins 248 and 548 can be formed in the lower frame 2 and the upper frame 5 at positions adjacent to the water stop line, the gap size can be set near the water stop line. For this reason, the clearance dimension between the vertical frame 3, the lower frame 2, and the upper frame 5 of a water stop line part, ie, the compression rate of the sealing material 4, can be set easily and correctly.

(5) The screw hole portions 28, 29, 58, 59 are continuous with a predetermined range of circular regions from the center position of the screw hole portions 28, 29, 58, 59, and the water stop line is formed in the circular region. It is set to be included. For this reason, when the screw 45 is screwed into the screw hole portions 28, 29, 58, 59, the water stop line can be arranged in a range where the force necessary for compressing the sealing material 4 by the tightening force of the screw 45 is reached. For this reason, the sealing material 4 can be reliably compressed at a predetermined compression rate in the water stop line portion, and the water stop performance can be reliably ensured.

(6) The protrusions 346 and 356 are formed at positions close to the nail fin portion 361 in the vertical frame 3. For this reason, when the lower frame 2 and the upper frame 5 are thermally expanded by direct sunlight or the like, the force on the nail fin portion 361 to which the force is most easily applied in the sealing material 4 can be supported by the protrusions 346 and 356. For this reason, even when the thermal expansion of the lower frame 2 and the like is repeated after the construction of the window frame 1, it is possible to prevent the sealing material 4 from being excessively crushed and to lengthen the period until the sealing material 4 is maintained. it can.
In particular, the protrusions 346 and 356 formed on the second shape member are not the screw hole portions 28, 29, 58, 59 in which the formation positions are restricted for setting the tightening force, but the screw hole portions 28, 29, 58, 59. Since it is in contact with the component mounting fins 248 and 548 closer to the nail fin portions 261 and 561, it is suitable for forming a gap as compared with the case where the protruding portions are brought into contact with the screw hole portions 28, 29, 58 and 59. The gap forming means can be arranged at a different place.
That is, when the lower frame 2 and the upper frame 5 are thermally expanded by direct sunlight or the like, the most force is applied to the seal material 4 because the vertical frame 3 is fixed to the casing, so that the frame itself is deformed. This is the nail fin portion 361 where the force cannot be released.
Therefore, the closer the formation position of the projections 346 and 356 in the prospective direction at the joint surface between the vertical frame 3 and the lower frame 2 or the upper frame 5 is closer to the nail fin portion 361, the more force is applied to the nail fin portion 361 during thermal expansion. Can be effectively supported by the protrusions 346 and 356. According to the present embodiment, the protrusions 346 and 356 are parts closer to the nail fin portions 261 and 561 than the screw holes 28, 29, 58, and 59 and the rail portions 21, 22, 23, 51, 52, and 53. Since the mounting fins 248 and 548 are in contact with each other, it is possible to effectively prevent the seal material 4 from being excessively crushed even when the thermal expansion of the lower frame 2 or the like is repeated.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the structure similar to the said 1st Embodiment, and description is abbreviate | omitted or simplified.
The window frame 1A according to the second embodiment is characterized in that the projection 345, which is a gap forming means formed by extrusion processing on the vertical frame 3A, is brought into contact with the contact fin 249 formed on the lower frame 2A. It is different from the embodiment.
That is, the lower frame 2A is different from the lower frame 2 of the first embodiment in that the lower frame 2A includes a contact fin 249 protruding from the second upright portion 246 to the room side, and the other configurations are the same.

  On the other hand, in the vertical frame 3 of the first embodiment, the protrusions 346 are formed at positions corresponding to the component mounting fins 248, whereas in the vertical frame 3A of the second embodiment, the contact fins 249 are provided. A protrusion 345 is formed at a position in contact with the projection.

  The sealing material 4A sandwiched between the vertical frame 3A and the lower frame 2A includes hole portions 411 and 421 corresponding to the screw hole portions 28 and 29, and a hole portion 43 corresponding to the protruding portion 345.

Also in this embodiment, when the screws are screwed into the screw holes 28 and 29 from the vertical frame 3A to join the vertical frame 3A and the lower frame 2A, the protrusion 345 contacts the contact fin 249, and the vertical frame 3A and the lower frame 3A The gap dimension between the frames 2 </ b> A is set to the protruding dimension of the protrusion 345.
For this reason, the sealing material 4A sandwiched between the vertical frame 3A and the lower frame 2A is compressed to the thickness of the gap dimension, that is, a predetermined compression rate. Therefore, the water stop performance in the water stop line formed along the surface of the lower frame 2A can be ensured as in the first embodiment.

In the second embodiment as described above, the same effects as those of the first embodiment can be obtained.
That is, since the contact part (metal touch part) with which the protrusion 345 and the contact fin 249 contact is formed at a position different from the water stop line, the water stop line is continuously provided in the expected direction of the window frame 1A. It can form and can secure water stop performance.
Further, the abutting portions of the protruding portion 345 and the abutting fin 249 are formed on the back side of the second upright portion 246 that is a part of the water stop line, and the projecting portion 345 and the abutting fin 249 are provided in the window frame. It is not exposed to the inner peripheral surface of 1A, and the deterioration of the design property can be prevented.
Further, the protrusion 345 can be processed simultaneously with the punching of the screw holes 341 and 342, and an increase in the number of manufacturing steps can be prevented.
In addition, since the contact fin 249 is newly formed to contact the protrusion 345, it can be freely formed at a position suitable for gap formation.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the structure similar to the said 1st Embodiment, and description is abbreviate | omitted or simplified.
The lower frame 2B of the third embodiment is a heat insulating shape member in which a resin heat insulating material 70 is injected in the middle of the prospective direction. A connecting portion 71 that divides this space vertically is formed in the first hollow portion 250A on the outdoor side of the heat insulating material 70. A space between the connecting portion 71 and the second surface portion 242 is a drainage path 700. That is, the connecting portion 71 is the lower surface of the drainage path 700, and the second surface portion 242 is the upper surface of the drainage path 700.

  For this reason, the water stop line forming part of the lower frame 2B is constituted by the end pieces of the draining piece part 251, the first surface part 241, the connecting part 71, the connecting part 253, the heat insulating material 70, the third surface part 243, and the mounting part 27. Has been. That is, the water stop line is formed along the lower surface of the drainage path 700.

  In addition, in the lower frame 2B, a part of the water stop line of the connecting portion 71 part is out of the circular areas 281 and 291. 3 is formed so that the water stop line portion deviated from the circular regions 281 and 291 is included in the circular region 721 centering on the third screw hole 72.

Since the seal material (not shown) disposed between the end surface of the lower frame 2B and the joint surface of the vertical frame (not shown) is provided so as to close the end surface of the drainage path 700 and the first hollow portion 250A, the screw hole portion 28 and the second surface portion 242 are also arranged. Moreover, it arrange | positions also at the end surface position of the heat insulating material 70 or the 2nd screw hole part 29. FIG.
Therefore, the vertical frame 3 is formed with a protrusion 348 that abuts against the second surface portion 242 that is the upper surface of the drainage path 700.
In addition, resin cover members 75 and 76 having a film laminated on the upper surface are attached to the upper surface of the lower frame 2B.

Also in the third embodiment, since the protruding portion 348 is brought into contact with a position different from the end surface of the second surface portion 242, that is, the water stop line, the same effects as the first embodiment can be obtained. Can do.
Furthermore, since the protrusion 348 is formed at the position outside the nail fin portion 261 in the prospective direction of the lower frame 2B, even if the portion outside the lower frame 2B is thermally expanded by direct sunlight, The protrusion 348 abuts against the second surface portion 242 located on the outdoor side of the nail fin portion 261, so that the stress can be effectively supported. Therefore, it is possible to prevent an excessive stress from being applied to the sealing material due to the thermal expansion of the lower frame 2B.

[Modification]
In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the window frame 1 (frame body) used for the sash window as a joinery has been described as an example. However, the joint structure in the present invention is not limited to that applied to such a sash window. . That is, it is possible to use any joinery in which it is necessary to form a water stop line at the joint when the shape members are joined to ensure water stop performance. For example, the present invention may be applied to various building materials such as a door frame provided at a doorway of a building and a door frame of a bathroom door provided between a bathroom and a dressing room. Further, the joining structure of the present invention is not limited to the window frame 1 and the door frame, but may be one that joins the shoji materials (upper, lower, and vertical) supported by the window frame and the door frame.

Further, in each of the embodiments, the protrusions 346, 356, 345, and 348 as the gap forming means are replaced with the component mounting fins 248 and 548, the contact fin 249, and the second surface portion of the lower frame 2 and the upper frame 5. Although it is made to contact | abut to 242, it is good also as a clearance gap formation means by forming the projection part contact | abutted to the other part of the lower frame 2 or the upper frame 5. FIG.
For example, the protrusions as the gap forming means provided in the vertical frame 3 may be formed at positions where they contact the outer rail portion 21, the inner rail portion 22, the screen door rail portion 23, the mounting portion 27, etc. of the lower frame 2. . Similarly, you may form in the position contact | abutted to the outer rail part 51 of the upper frame 5, the inner rail part 52, the screen door rail part 53, and the attaching part 57. FIG. In short, the protruding portion may be formed at a position in the lower frame 2 or the upper frame 5 that is in contact with a profile portion that is different from the water stop line and different from the screw hole portion.

  Furthermore, in the above-described embodiment, the protrusions 346, 356, 345, and 348 are formed by extrusion processing. For example, a rib that is continuous along the longitudinal direction of the vertical frame is formed during extrusion of the vertical frame. A portion of the rib positioned on the water stop line may be cut out, and the rib portion that contacts the lower frame 2 or the upper frame 5 may be left to form a protrusion. However, there is an advantage that the processing cost is lower when the protruding portion is formed by extrusion processing as in the embodiment.

Moreover, in the said embodiment, although the clearance gap formation means was formed in the vertical frame side, you may form in a lower frame or an upper frame side. For example, the protruding portion may be formed on the end surface of the lower frame at a portion other than the water stop line by cutting away the protruding portion that contacts the vertical frame on the end surface of the lower frame.
Furthermore, it is good also as a projection part by crushing and forming a protrusion part in the end surface of a lower frame, and it is good also as a projection part by giving a build-up by welding etc.

Further, the first shape member and the second shape member are provided with nail fins for fixing the frame, and when these shapes are arranged in a position exposed to direct sunlight such as a building window, the gap forming means The arrangement position in the prospective direction is preferably provided between the nail fin portion and the end face on the outdoor side of the shape member. Specifically, the position in the prospective direction of the gap forming means may be the same position as the nail fin part, or may be a position outside the nail fin part.
On the other hand, when each shape member is arranged at a position where it is not exposed to direct sunlight, such as a bathroom, the arrangement position in the prospective direction of the gap forming means is limited to the space between the nail fin portion and the end face on the outside of the shape material. It may be a position on the indoor side of the nail fin portion.

  In addition, the lower frame 2 and the upper frame 5 are the first shape members, and the vertical frame 3 is the second shape member, but the end surface of the vertical frame is brought into contact with the joining surface of the upper surface of the lower frame and the lower surface of the upper frame. As in the case of joining, the vertical frame may be the first profile and the upper and lower frames may be the second profile.

  Furthermore, in the first and second embodiments, two screw hole portions 28, 29, 58, 59 are formed in the lower frame 2 and the upper frame 5, but the number of the screw hole portions may be one, There may be more than one. Also in the third embodiment, the number of bis holes is not limited to three. That is, what is necessary is just to set so that a water stop line may be included in the circular area | region where the fastening force by the screw screwed in a screw hole part is added.

  Furthermore, when each shape member is connected by a connection fitting, it is not necessary to form a screw hole portion in the first shape member. In this case, a gap may be formed by disposing a gap forming means at a position other than the water stop line at the joint between the first profile and the second profile. That is, the present invention can also be applied to joining of shape members that do not have a screw hole portion.

In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of material, quantity, and other detailed configurations.
Therefore, the description limiting the shape, material, etc. disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded the limitation of one part or all of such restrictions is included in this invention.
