[0001]
BACKGROUND OF THE INVENTION
The panel intermediate portion supporting device according to the present invention supports the intermediate portion of the glass panel constituting the wall surface of the building, and prevents the glass panel from being excessively bent in the inside / outside direction of the building during a strong wind.
[0002]
[Prior art and problems to be solved by the invention]
It is widely practiced to construct (cover) the outer wall surface of a building with a glass panel. In recent years, it has been considered to use a large glass panel in consideration of the design of the outer wall surface of the building. In particular, the use of a glass panel having a height equivalent to the first floor of the building is also under consideration.
[0003]
When a glass panel having such a large height is used, the bending of the glass panel in a strong wind cannot be ignored. That is, when strong wind blows on the glass panel, the glass panel is pushed to the indoor side, and the glass panel tends to bend to the indoor side. On the other hand, when a strong wind parallel to this glass panel blows, the pressure on the outdoor side of this glass panel is lower than the pressure on the indoor side, this glass panel is pushed to the outdoor side, and this glass panel is moved to the outdoor side. It tends to bend.
[0004]
If the bending of the glass panel generated in this way becomes significant, the glass panel breaks, and it is necessary to take measures. Conventionally, the left and right side edges of the glass panel have been generally restrained by verticals. However, when verticals are used, these verticals become conspicuous when the building is viewed from the outside. The design cannot be made clean.
[0005]
For this reason, the realization of the structure which supports the intermediate part of the said glass panel so that it is not conspicuous with respect to the support pillar of a building is desired. Further, since the glass panel and the support column are relatively displaced in various directions during the earthquake, the support device can absorb the relative displacement in order to prevent the glass panel from being broken during the earthquake. Must be a structure.
The panel intermediate support device of the present invention has been invented in view of such circumstances.
[0006]
[Means for Solving the Problems]
The panel intermediate portion supporting device of the present invention supports the intermediate portion of the panel constituting the outer surface of the building, and prevents the panel from being excessively bent in the inner and outer directions of the building.
Such an intermediate panel supporting device of the present invention includes a coupling beam, a swing bracket, a panel side coupling bracket, a pin, and an insertion hole. Of these, the connecting beam is supported and fixed to the support column fixed to the building in a state of projecting from the support column toward the outdoor side. The swing bracket is supported at the distal end of the coupling beam so as to be swingable and displaceable about a horizontal axis disposed in the horizontal direction. The panel-side coupling bracket is provided in a state of being supported by an intermediate portion of the panel and being superimposed on the swing bracket in the vertical direction. The pin is supported in the vertical direction on one of the panel side coupling bracket and the swing bracket. Further, the insertion hole is formed in the vertical direction in the other of the panel side coupling bracket and the swing bracket. And the displacement regarding the inside-and-outside direction of the said building of the said panel side coupling bracket is suppressed by inserting the said pin loosely in this insertion hole.
[0007]
[Action]
According to the panel intermediate portion support device of the present invention configured as described above, the intermediate portion of the panel can be supported inconspicuously with respect to the support column fixed to the building. That is, since the intermediate portion of the panel is supported by the support pillar via the coupling beam, the swing bracket, the panel side coupling bracket, and the pin, even if a pressure difference occurs between both surfaces of the panel, It is possible to prevent the panel from being bent excessively beyond the range in which the pin can be displaced indoors and outdoors inside the insertion hole. Moreover, only a part of the panel side coupling bracket is exposed to the outdoor side of the panel, and is not noticeable when viewed from the outdoor side.
In the event of an earthquake, the swing bracket swings about the horizontal axis with respect to the coupling beam, or the pin relatively displaces vertically and horizontally relative to the insertion hole, The panel and the support column are relatively displaced in various directions. For this reason, in the event of an earthquake, a large force is not applied to the portion where the panel side coupling bracket is supported and fixed at the middle portion of the panel, and the panel is not cracked.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
1 to 11 show a first example of an embodiment of the present invention. As shown in FIGS. 1 to 3, the intermediate support device for the panel of this example supports two positions in the middle in the height direction of the left and right side edges of the glass panels 1 and 1 constituting the outer surface of the building, These glass panels 1 and 1 prevent excessive bending with respect to the inside and outside directions of the building. The upper and lower end edges of the glass panels 1 and 1 are supported by support frames 4 and 4 fixed to the ends of the floors 2 and 2 of the building by support channels 3 and 3, respectively.
[0009]
As described above, two positions in the middle in the height direction of the left and right side edges of each glass panel 1 and 1 with the respective upper and lower end edges supported by the support frames 4 and 4 are defined in the present invention. It is supported by support columns 5 and 5 fixed to the building side by means of a panel intermediate support device. Each of the intermediate support devices for the panel includes a coupling beam 6, a swing bracket 7, a panel-side coupling bracket 8, a pin 9, and an insertion hole 10.
[0010]
Of these, the connecting beam 6 is attached to the support column 5 fixed to the building via the support channels 3 and 3 from the support column 5 to the outdoor side (the left side of FIGS. 2, 4, 5 and 8, FIG. 6 and 7 are supported and fixed in a state of projecting toward the lower side. That is, the base end surface of the coupling beam 6 formed on the outdoor side surface of the support column 5 in accordance with the cross-sectional shape of the coupling beam 6 and having a slit-like through hole that is long in the vertical direction is formed on the inside of the support column 5. In a state of being abutted against the end portion on the inner side of the peripheral surface, the outer peripheral surface of the intermediate portion of the coupling beam 6 and the inner peripheral edge portion of the through hole are welded. A circular hole 11 (FIGS. 6 to 7) is formed at the distal end portion (outdoor end portion) of such a coupling beam 6.
[0011]
The swing bracket 7 is constructed by cutting an aluminum alloy drawing material, and is supported by a bolt 12 and a nut 13 at the tip of the coupling beam 6. In the illustrated example, two rocking panels 6 are supported at the tip of one coupling beam 6 in order to support an intermediate portion between two glass panels 1 and 1 that are horizontally adjacent by one coupling beam 6. The moving brackets 7 and 7 are supported. Each of the swing brackets 7 and 7 is formed by providing a locking cylinder portion 15 at the tip end (outdoor end portion) of the flat mounting plate portion 14. And the said insertion hole 10 is formed in this latching cylinder part 15 up and down. In the case of this example, the insertion hole 10 has a circular cross section and is formed so as to penetrate the locking cylinder portion 15 in the vertical direction. Further, a circular hole 16 is formed in the base end portion (indoor end portion) of the mounting plate portion 14.
[0012]
Each of the swinging brackets 7 and 7 each having the above-described configuration has the sliding beam 17 interposed between the mounting plate portion 14 and the side surface of the coupling beam 6. Overlapping. Then, the bolts 12 inserted through the circular holes 11 and 16 and the nuts 13 are screwed together so that the swing brackets 7 and 7 are coupled and supported to the distal ends of the coupling beams 6. In this state, the bolt 12 functions as a horizontal axis described in the claims, and the swing brackets 7 and 7 are supported so as to be swingable and displaceable around the bolt 12.
[0013]
The panel-side coupling bracket 8 is constructed by cutting an aluminum alloy drawing material and further cutting a part thereof, and is supported at the intermediate portion in the height direction of the glass panels 1 and 1. . In the illustrated example, the panel-side coupling bracket 8 has a pin support portion 18 for supporting the pin 9 on the base half (indoor half) and a panel holding portion on the front half (outdoor half). 19 are provided. Of these, the pin support portion 18 has a pair of upper and lower support arm portions 20, 20, and the support arm portions 20, 20 have support holes 21, 21 concentric with each other. In the state in which the intermediate support device for the panel of the present invention is configured, the support arm portions 20 and 20 are disposed above and below the locking cylinder portion 15 provided at the tip end portion of the swing bracket 7 (locking). (It is provided in a state where it is superimposed on the cylindrical portion 15 in the vertical direction).
[0014]
And the intermediate part of the said pin 9 which made the both upper and lower ends fit to the said support holes 21 and 21 is inserted loosely in the insertion hole 10 provided in the said latching cylinder part 15. As shown in FIG. The distance D 20 between the pair of support arm portions 20 and ₂₀ is larger than the height H ₁₅ of the locking tube portion 15 (D ₂₀ > H ₁₅ ). Accordingly, the panel-side coupling bracket 8 can be slightly displaced relative to the swing bracket 7 in the vertical direction and in the horizontal direction (three-dimensional direction). The pin 9 may be formed by screwing a male screw portion formed at the upper end portion or the lower end portion thereof with a female screw formed on the inner peripheral surface of either of the support holes 21 and 21. The support holes 21 and 21 may be simply inserted without providing any part.
[0015]
The intermediate portions in the height direction of the left and right side edges of the glass panels 1 and 1 are coupled to the panel holding portion 19 of the panel side coupling bracket 8 as described above so as to be slightly swingable. For this purpose, the panel holding portion 19 is provided with a holding groove 22 having a width dimension W ₂₂ larger than the thickness dimension T ₁ of each glass panel 1. Each of these glass panels 1 has a sealing material 23 having elasticity between both sides of the side edge portion and both inner side surfaces of the holding groove 22 in a state where the side edge portion enters the holding groove 22. , 23 is filled and supported by the panel holding portion 19. Accordingly, the glass panels 1 and the panel-side coupling bracket 8 are coupled so as to be slightly swingable and displaceable based on the elastic deformation of the sealing materials 23 and 23.
[0016]
According to the intermediate part support device for a panel of the present invention configured as described above, the intermediate part in the height direction of the glass panels 1 and 1 can be supported inconspicuously with respect to the support column 5 fixed to the building. That is, since the intermediate portion in the height direction of each glass panel 1, 1 is supported by the support column 5 via the coupling beam 6, the swing bracket 7, the panel side coupling bracket 8, and the pin 9, Even if a pressure difference occurs between both surfaces of the glass panels 1, the glass panels 1, 1 are displaced indoors and outdoors inside the insertion hole 10 provided with the pin 9 in the swing bracket 7. Excessive bending beyond the possible range can be prevented. Moreover, only the tip of the panel-side coupling bracket 8 is exposed to the outdoor side of the glass panels 1 and 1 and does not stand out when viewed from the outdoor side.
[0017]
In the event of an earthquake, as shown by the solid and broken lines in FIG. 11, the swing bracket 7 swings around the bolt 12 with respect to the coupling beam 6, or the pin 9 is inserted. By relative displacement in the vertical direction and horizontal direction with respect to the hole 10, the glass panels 1 and 1 and the support column 5 are relatively displaced in various directions (in FIG. 11, the neutral positions of the members are (Indicated by a dotted line). That is, when the glass panels 1 and 1 and the support column 5 are displaced in the vertical direction, the locking cylinder portion 15 provided at the distal end portion of the swing bracket 7 is the base half of the panel side coupling bracket 8. The vertical displacement of each glass panel 1, 1 and the support column 5 is absorbed within a range that can be displaced between the pair of upper and lower support arm portions 20, 20 provided in the upper and lower portions.
[0018]
Further, when the glass panels 1 and 1 and the support column 5 are displaced in the horizontal direction, the range in which the pin 9 can be displaced in the radial direction inside the insertion hole 10 provided in the locking cylinder portion 15. The horizontal displacement between the glass panels 1 and 1 and the support column 5 is absorbed. Further, when the positional relationship between the glass panels 1 and 1 and the panel-side coupling bracket 8 is displaced due to an earthquake or strong wind, the sealing materials 23 and 23 are elastically deformed to absorb the displacement. To do. By these actions, it is possible to prevent a large force from being applied to the portion where the panel-side coupling brackets 8 and 8 are supported and fixed at the intermediate portion of the glass panels 1 and 1 in the event of an earthquake. 1 can be prevented from breaking.
[0019]
In addition, since the displacement in the horizontal direction at the time of the earthquake is smaller than the allowable deflection amount of each of the glass panels 1 and 1, each of the above-mentioned at the time of strong wind even if the horizontal displacement at the time of the earthquake can be absorbed. It is possible to reliably prevent the glass panels 1 and 1 from bending beyond the allowable limit.
[0020]
Next, FIG. 12 shows a second example of the embodiment of the present invention. In the case of this example, the pin support part 18a provided in the base half part of the panel side coupling bracket 8a is comprised by one support arm part 20a provided in the upper half part. In the state in which the intermediate support device for the panel is configured, the support arm portion 20 a is disposed above the locking cylinder portion 15 provided at the distal end portion of the swing bracket 7. The lower end portion of the pin 9 whose upper end portion is fitted into the support hole 21 formed in the support arm portion 20a is loosely inserted into the insertion hole 10 provided in the locking cylinder portion 15. The intermediate portion or the upper end portion of the pin 9 may be loosely inserted into the support hole 21, may be internally fitted with an interference fit, or may be fixed with screws. Other configurations and operations are the same as in the case of the above-described first example, and thus overlapping illustrations and descriptions are omitted.
