Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a support structure for a glass sheet.

[0002]

2. Description of the Related Art Sheet glass is generally mounted and supported on a metal sash frame. However, since the metal sash frame is provided so as to protrude from the plate glass surface, the design of the entire building is inferior. Therefore, in recent years, plate glass support structures having no members protruding from the surface of the glass sheet have been actively developed.

As one example, a structural silicone construction method (hereinafter referred to as “SSG construction method”) is known. The SSG construction method includes a metal member made of aluminum or the like that substantially supports the sheet glass, and a structural seal made of a silicone sealant or the like that joins the metal member and the sheet glass. Glued with a seal. Therefore, according to the SSG construction method, the panel can be held without projecting a metal member such as a metal sash on the outer surface of the building, and the design is improved.

[0004] As another example, a perforated tempered glass construction method (hereinafter referred to as "DPG construction method") is known. In the DPG construction method, countersunk holes are machined at four corners of the tempered glass, and countersunk bolts that fit into the countersunk holes are attached to support the sheet glass. According to this DPG construction method, since there is no member that protrudes from the sheet glass surface to the outer surface of the building, the design is improved.

[0005] However, the SSG construction method has a problem of long-term durability because the sheet glass is supported by bonding the sheet glass and the metal member with a structural seal, and thus there is a problem of long-term durability. Two of the four sides of the sheet glass are attached to the sash frame. General.

On the other hand, in the DPG construction method, since the surface of the countersunk bolt is visible on the glass surface, the design of the portion is inferior and the supporting member is preferably invisible. Further, in the DPG construction method, since the mounting hardware protrudes largely toward the indoor side, there is a problem that the cleaning is troublesome.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has an object to provide a supporting structure for a sheet glass which has a long-term durability and does not protrude or expose a mounting member from a glass surface. Aim.
