Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gasket for constructing a curtain wall of a building and a curtain wall mainly composed of this gasket, and more particularly to a gasket and a curtain wall in which glass is fitted to form a window.

[0002]

2. Description of the Related Art When a building has a skeleton that is a main structure for retaining its shape, the wall body is called a curtain wall in the sense that it simply partitions a space.
Such curtain walls have standardized standards, are mass-produced in factories, and are attached as outer wall surfaces of buildings by using frames such as columns and beams. The glass is fitted to form the window.

A conventional window curtain wall is formed of a metal plate, a precast concrete plate or the like into a rectangular shape. However, since it is large in size, it has a surface inconvenient for transportation and storage. . In addition, although it is aimed at weight reduction,
The unit itself had a considerable weight, and it was necessary to handle it with sufficient care. As an alternative to such a curtain wall, a curtain wall mainly made of a rubber gasket is used.

FIG. 6 shows an example of a gasket used in a conventional curtain wall. A pair of sandwiching pieces b and c are provided on both sides in the length direction of an elongated body a made of an elastic material such as rubber. Is provided to form a fitting groove d, and a zipper e can be attached to and detached from the center of the elongated body a on the side of the sandwiching piece b in the entire length in the length direction. A gasket having such a shape has a predetermined length and width. It is assembled into a rectangular frame body having the dimensions and sizes. The surface having the zipper e faces the surface of the building, and on the indoor side, a rectangular frame having a shape corresponding to the size of the gasket is formed by a supporting member f made of, for example, H-shaped steel, and ribs on one side of the supporting member f are formed. The curtain wall is constructed by integrally connecting g to the gasket.

In the curtain wall as described above, the supporting member f is fixed to a beam material such as a pillar or a beam of a building. To form a window, the zipper e is removed to sandwich both sides of the building. With the piece b in a free state, open the sandwiching pieces b and c, insert the end of the glass h between them, and insert the zipper e to press the sandwiching piece b against the glass h surface to stabilize the glass h. It is something that is fixed.

However, since such a curtain wall has a structure in which the glass h is supported on both sides of the gasket, it is difficult to form a single rectangular frame by itself, and it is continuous in the vertical and horizontal directions. There was no choice but to use a composite structure having a plurality of rectangular frames. Therefore, as an alternative to the above-mentioned gasket, a gasket as shown in FIG. 7 that can be formed in a single rectangular frame is used. In this gasket, a long body i made of an elastic material such as rubber is formed in an L shape, one of the L shapes is a connecting portion j, and a portion connected to this at a right angle is a sandwiching piece k. is there.

Such a gasket can be formed as a single unit into a rectangular frame body having predetermined vertical and horizontal dimensions, and a supporting member 1 formed in accordance with the size of the rectangular gasket is used as a supporting member for a building girder. The glass h is fixed on the surface of the support member l (outside the building), and the end of the glass h is clamped by inserting the connecting portion j of the gasket into the support member l at a predetermined position. And the supporting member 1 are stably fixed.

Has a low work efficiency and requires a long time for the construction work, which poses a risk of falling workers. Further, when the adjacent gaskets are not densely packed, there is a risk that the rainwater that has entered between the gaskets may corrode the support member 1 or that the rainwater may pass through the support member 1 and enter the interior.

In view of the gaskets and supporting members used in the conventional curtain wall described above, the present invention can be formed into a rectangular frame by itself, and the construction work of the curtain wall can be performed mainly on the indoor side. It is an object of the present invention to provide a gasket for a curtain wall, which can prevent rainwater from entering by tightly closing the gaskets. It is another object of the present invention to provide a curtain wall having a support member that can be formed as a single piece into a rectangular frame and can be integrally attached with a gasket.
