Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a curtain wall that supports glass without leaving a blind eye on the outer surface of a building. More specifically, the present invention relates to a curtain wall on the outside of a building. A plurality of rectangular glasses supporting out-of-plane wind pressure at both lateral ends of the provided stand were arranged side by side in the vertical direction, and adjacent to the indoor side of the vertically adjacent part of the glass. The present invention relates to a glass support structure for a curtain wall in which an eye is laid horizontally across a pallet and the weight of the glass is supported by the eye.

[Conventional technology]

Recently, in a glass curtain wall of a high-rise building, a new design in which most of the outer surface is covered with glass by erecting and elastically adhering the glass with a sealing material to the outer surface Has come to be widely adopted. On the other hand, the glass used for such a high-rise building usually requires an appropriate glass self-supporting frame because it is thick and therefore heavy, but the supporting frame surrounding the four sides of the square glass used is If you can see it, the aesthetic appearance will be diminished, so
There is a tendency that only the self-weight support is elastically bonded and the support frame visible from the outside is omitted. However, in the earthquake-prone country, omitting all such supporting frames is not a problem in terms of durability. Therefore, there is also a method of covering the lateral support frame with the sheet tongue material.

As a typical example of the above, the curtain wall for building disclosed in JP-A-60-212547 is known.

This method supports the out-of-plane wind pressure by erection and blindness at each end of the glass arranged in the up-down direction. The lower part of the upper glass supports the self-weight of the glass by receiving the lower end of the upper glass by the section, and the amorphous sealing material is filled between the lower end of the upper glass and the upper end of the lower glass. As for the out-of-plane support, the gap between the clip that engages the picking device attached to the panel and the picking device allows the in-plane rotation of the glass due to the interlayer displacement of the building due to the earthquake. It was

[Problems to be solved by the device]

Although the above-mentioned seamless extension has sufficient strength to support the weight of the glass itself, it requires a lot of material because it is integrally formed with the seamless eye and is a front-supporting type with a through-hole. It has the drawback of becoming expensive. In Japan, which is an earthquake-prone country, the glass causes in-plane rotation (rocking) due to the interlayer displacement of the building, but if it is a front support, the upward movement dimension due to the in-plane rotation of the lower edge of the glass is large , There is a risk that the irregular sealing material will peel off.

The present invention aims to solve these problems in the prior art and to solve the problems of the invention.

[Means for Solving the Problems]

As a means for solving the above-mentioned problems, the present invention is to arrange erections on the outer side of the building body in parallel, and lay a seamless line between the erections to make the end part of the erections. A surface that acts on the glass by connecting and arranging a plurality of plate-shaped glasses so as to be adjacent to each other in the up-down direction and the left-right direction, and connecting their edge portions to the upright or the seamless or both of them. In a glass curtain wall supporting the outside wind pressure and supporting the self-weight of the glass by the blind disposed on the indoor side of the glass, the glass is at least in the plane of the glass with respect to the blind. A short glass receiving part which is engaged so as to be capable of relatively slight displacement and has a part which is horizontally taken out so as to be supported at least at one position near the center of the lower end edge of the glass. Is provided as a pair separate from the blind, and the base of the glass receiving member is engaged with the blind and slidably supported in the vertical direction, and the vertical position of the glass receiving member is fixed by a screw. Provided is a glass support structure for a curtain wall, which is characterized by being adjustable.

[Action]

According to the present invention, a short piece of glass which is engaged with the eyeglass so as to be relatively displaceable at least in the plane of the glass and supports at least one portion of the lower edge of the glass near the center thereof. The glass receiving member of is provided as a pair different from the eyeless, the base is supported by the eyelessly so as to be slidable in the vertical direction, and the position in the vertical direction can be adjusted by the screw. Compared to the structure that directly supports the glass without eyes, not only the amount of material used for the glass receiving member is reduced, but also in-plane rotation (locking) of the glass is reasonably performed in the event of an earthquake. In that case, since relative displacement does not occur between the glass and the part incidental thereto, that is, the gasket and the gasket receiving member, there is no fear that the sealing material peels off. Also, since the vertical position of the glass receiving member can be freely adjusted with screws, fine adjustment of the mounting position of the glass to align the glass in the vertical and horizontal directions, or when the position of the glass is misaligned The work of making corrections becomes easier.

〔Example〕

Hereinafter, embodiments will be described with reference to the drawings. 1 is a longitudinal sectional view showing the structure of the present invention taken along the line I--I of FIG. 2, FIG. 2 is a front view of a curtain wall to which the present invention is applied, and FIG. 3 is III of FIG. FIG. 3 is a cross-sectional view showing line III.

As shown in FIG. 2, erections 1 are arranged side by side on the outside of the building frame via fasteners or the like (not shown), and both sides are fitted in fitting grooves (not shown) formed on both sides of this erection. A plurality of transparent prismatic glasses 2 supporting the out-of-plane wind pressure of this portion by swallowing the lateral end portion are juxtaposed vertically in a vertical direction. The glass 3 located outside the pillar 4 can be made opaque or translucent so that the pillar 4 cannot be seen through from the outside. On the indoor side of the vertically adjacent portion of the glass, seamless eyes 5 and 5A that connect the adjacent uprights 1 are laid horizontally.

The present invention indirectly supports the own weight of the glasses 2 and 3 by the blinds 5 and 5A. As shown in FIG. 1, the outdoor surface or outer surface facing the blinds 5 and 5A of the glasses 2 and 3 is not shown. In the upper and lower parts, fitting grooves 6A and 6B are formed in the longitudinal direction in a seamless manner with their openings facing each other. Reference numeral 7 is a cantilever type glass receiving member composed of a vertical piece 7A and a take-out piece 7B extending from the upper end of the vertical piece in the outdoor direction. There is. As shown in FIG. 1, the upper and lower end portions of the vertical piece 7A of the glass receiving member 7 are seamless.
It is possible to slidably engage with the fitting grooves 6A and 6B of 5A, and to position the screw 8 at an appropriate position with respect to the eyes to fix the upward movement or allow only the upward movement. . The horizontal portion of the tip of the short take-out piece portion 7B supports the portion of the upper glass near the center of the lower edge portion. For this reason, it is preferable that the glass receiving member 7 is made of a material having a relatively high strength or a thick member. One may be used to support one glass 2 or 3, but two or more are used. It is preferable.

9A and 9B are gasket holder receivers bolted inseparably, and the gasket receivers 11A and 11B connected to the rubber gaskets 10A and 10B adhered to the indoor surface of the glass by the sealing material are attached to the blind eyes 5 and 5A The in-plane rotation of the glass 2 and 3 is permitted by engaging the gasket holder receivers 9A and 9B which are relatively displaceable in the same plane, and the out-of-plane wind pressure acting on the glass 2 and 3 is applied. It is designed so that it can be transmitted to the blind eyes 5 and 5A and supported.
Also, the gasket 10 near the upper end of the lower glass 2, 3
B, gasket holder 11B has a rubber waterproof gasket 1
2 is engaged. Of the above-mentioned members, the gasket holder receivers 9A and 9B are short members, but other members, that is, the gaskets 10A and 10B and the gasket holders 11A and 11B.
The waterproof gasket 12 is a long member having substantially the same length as the unsealed gasket.

Although the glass support structure is described in the above description, a panel other than glass may be used instead of glass.

[Effect of device]

According to the present invention, since the short glass receiving member for supporting the central portion of the lower edge of the glass is formed as a pair different from the blind, the glass is directly supported by the blind. Compared with the structure, the material used for the glass receiving member is reduced, which not only helps in cost reduction, but also the material of the glass receiving member according to the size and weight of the glass used,
Since the size, shape, number, etc. can be arbitrarily changed, the degree of freedom in design is increased, which is convenient.

In addition, the glass is engaged with the eye so that it can be rotated in-plane, the base of the glass receiving member is supported by the eye without sliding, and the vertical position of the glass receiving member is adjusted with a screw. It is possible to adjust the vertical position of the glass itself through the glass receiving member, and the in-plane rotation of the glass based on the interlayer displacement of the building during an earthquake etc. On the other hand, the support member is not overly stressed, and there is no fear that the sealing material between the glass and the incidental part of the glass will peel off.
