Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-walled glass curtain wall for an exterior wall of a building, and more particularly to a double-walled glass sealing structure and mounting structure.

[0002]

2. Description of the Related Art As a conventional sealing structure and mounting structure for double glazing, for example, as shown in Japanese Utility Model Laid-Open No. 4-56891, the outer periphery of two glass plates is provided on the spacer side with a partition plate as a boundary. High modulus type structural sealing material is filled with the medium modulus type structural sealing material on the sash side and cured to form a seal structure, and the wind pressure is received by the high modulus type structural sealing material. A sealing structure is provided with two kinds of sealing materials so that shear deformation due to interlayer displacement is received by the medium modulus type structural sealing material, and the opening side of the U-shaped cross section of the sash is inserted into the edge of one glass plate. It has been known that a sash is attached by filling and curing a medium-modulus type structural sealing material in the gap.

[0003]

The above-mentioned structural sealing material is an amorphous sealing material, and a paste-forming or putty-like sealing material is filled in the seal forming portion,
This is hardened and used as a sealing material with rubber elasticity, and because a sash is attached, it takes time and effort to control the quality and process of the sealing material, and the sealing material needs to be dried. There was a problem that it took time. Therefore, the present invention solves the conventional problems and provides a double-layered glass curtain wall having a seal structure and a mounting structure which can be easily installed in a sash frame and can be installed in a factory or on the spot. It is intended to be provided.

[0004]

[Means for Solving the Problems] In order to achieve the above object, the present invention makes two glass plates face each other via a spacer, hermetically seals the outer periphery of the spacer, and uses a sash frame. A curtain wall of double glazing fixed to a building frame, configured to press-fit an airtight insertion part provided on a fixed gasket into the space around the spacer to seal the double glazing. Is.
Further, the fixed gasket is provided with a mounting portion to the sash frame so that the double glazing can be mounted to the sash frame. Further, the fixed gasket is provided with a glass fitting groove so that the fixed gasket is fitted and clamped on the outer edge of the glass plate on the indoor side.

A load receiving bracket 14 is provided to receive the short lower end of the glass plate 3, and its rear part is fitted and locked to the sash frame 15 so as to receive and support the load of the double glazing. Has been done. And the sash frame 15 to which the double glazing and the fixed gasket 10 are attached
Is fixed by attaching it to a bracket fixed to the building frame. FIG. 2 shows a cross-sectional view of the vertical sealing structure and mounting structure in the AA cross section of the curtain wall 1. The outer side of the spacer 4 sandwiched between the two glass plates 2 and 3 is silicone. The sealing structure is formed only by the regular gasket as shown in FIG. 3 except that the sealing structure is formed by filling the paste-shaped or putty-shaped indeterminate sealing material 6 such as resin or synthetic rubber and adhering and curing it. Not not. A ridge 28 is attached to the vertical end edges of the glass plates 2 and 3, and the ridge 28 fixes the multi-layer glass to the sash frame 15. And left and right ridges 2
The space 8 and 28 is filled with the irregular sealing material 9 via the backup material 8 to form joints.
