Abstract

PROBLEM TO BE SOLVED: To provide a supporting hardware for glass plate which surely transfers a positive or negative wind pressure load from out-of-plane direction to a rib glass, and prevents breakage of a glass plate due to interlayer displacement thereof caused by an earthquake or the like, and to provide a glass plate bearing structure. SOLUTION: According to the glass plate bearing structure which is formed by aligning and erecting the face glasses side by side, and arranging the rib glasses orthogonally to the face glasses along longitudinal sides of the same, clamps having swing shaft portions, respectively, are placed in a pair of bored portions across a joint at desired locations in the vicinity of the abutting longitudinal sides of the face glasses. The glass plate bearer is formed of a pair of convex spherical washers having convex spherical surfaces to be arranged on both surfaces of a bored portion of the rib glass, a universal shaft slidably inserted into the convex spherical washers and the bored portion of the rib glass to connect both the clamps together at its ends, and a pair of concave spherical nuts screwed onto the universal shaft. The convex spherical surfaces of the convex spherical washers are slidably pinched by the concave spherical surfaces of the concave spherical nuts, and therefore the universal shaft of the rib glass is rotatable in the bored portion of the rib glass, to thereby absorb displacement of the face glasses.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a glass plate provided with rib glass as a reinforcing material, and more particularly to a support fitting for connecting between a face glass and a rib glass and a support structure therefor.

[0002]

2. Description of the Related Art As a method of supporting a glass sheet, various methods are known. In addition to an SSG method of bonding a glass sheet with a structural sealing material without exposing a sash frame to the surface, a frameless method is also available. As a method of constructing a glass screen, a point support method in which perforated portions provided at four corners of a glass plate are supported by support metal fittings, and a hole is not formed in a glass plate using vertical and horizontal joints between the glass plates. A point support method of sandwiching and supporting with metal fittings is well known at present, but a glass rib in which rib glass (also referred to as cubic glass) is erected as a reinforcing material at the vertical joints of a plurality of face glass arranged side by side. Construction methods are still widely used today.

A glass curtain wall provided with the rib glass as a reinforcing material is provided with a sash frame for supporting the upper side and the lower side of the face glass, and four sides of the rib glass provided on the vertical side of the face glass from the out-of-plane direction of the face glass. A wind pressure load is supported, and a structural sealing material is filled and bonded between the face glass and the rib glass.

[0004] However, on the upper floor of a high-rise building, the negative pressure is larger than the positive wind pressure applied to the face glass of the glass screen from the out-of-plane direction. Is set within the range of the allowable tensile stress of the structural sealing material.

In order to provide a structure that can withstand a wind load of a negative pressure as well as a positive pressure from an out-of-plane direction of a face glass, for example, a detailed description and drawings of a microfilm disclosed in Japanese Utility Model Application Laid-Open No. 132008/1988 are given. As shown, a countersunk hole provided in the face glass is fastened and fixed with a countersunk bolt and a nut, and a tip end of the countersunk bolt is connected to an L-shaped mounting bracket with a bolt and a nut to form an L-shaped mounting plate. Describes a structure in which the mounting bracket is fixed to rib glass with bolts and nuts.

[0006]

However, when rocking occurs in each of the side-by-side face glasses due to interlayer displacement due to an earthquake or the like, the face glass and the rib glass are connected and fixed to each other by the L-shaped metal fittings. Excessive force is applied to the surrounding area of the bracket, and the glass plate is likely to be damaged.

For example, Japanese Utility Model Laid-Open Publication No. 1-75509 discloses a glass plate supporting structure capable of coping with the occurrence of such interlayer displacement. In this case, the first mounting bracket is tilted with respect to the glass screen and the second mounting bracket slides with the first mounting screen, so that even when the glass screen is tilted, the face glass is not tilted. There is a configuration in which this deformation force is hardly transmitted and the surface glass is not damaged.

[0008] However, the one disclosed in Japanese Utility Model Laid-Open Publication No. 1-75509 discloses that a movable mechanism including a projection of a metal fitting for connecting glass plates is exposed, so that not only the inside of the room but also the transparent glass plate is used. Since it is visible from the outside, it is not good in appearance and is not preferable as a building using a transparent glass plate.

[0009]

It is.
