Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a glass plate support structure in which rib glass is provided as a reinforcing material, and more particularly to a support metal fitting for connecting between a face glass and a rib glass and the support structure thereof.
[0002]
[Prior art]
Various methods are known for supporting glass plates. In addition to the SSG method, in which a glass plate is bonded and fixed with a structural sealing material without exposing the sash frame to the surface, a frameless glass screen is used. As a construction method, the point support method that supports the perforated parts provided at the four corners of the glass plate with support metal fittings, and the glass plate using the vertical and horizontal joints between the glass plates is not perforated and clamped with the metal fittings The point support method to support is well known at present, but the glass rib method with rib glass (also called vertical glass) standing upright as a reinforcing material on the vertical joints of a plurality of face glass arranged side by side is still present It is still widely adopted.
[0003]
The glass curtain wall provided with the rib glass as a reinforcing material has a wind pressure load from the out-of-plane direction of the surface glass at the four sides of the sash frame supporting the upper side and the lower side of the surface glass and the vertical side of the surface glass. Further, a structural sealing material is filled and adhered between the face glass and the rib glass.
[0004]
However, on the upper floors of high-rise buildings, the negative pressure is greater than the positive wind pressure from the out-of-plane direction applied to the glass surface of the glass screen. There is a restriction that the sealing material is within the allowable tensile stress range.
[0005]
In order to make the structure capable of withstanding not only the positive pressure from the out-of-plane direction of the surface glass but also the negative wind load, etc., it is shown in the detailed description and drawings of, for example, Japanese Utility Model Publication No. 63-132008. As shown in the figure, the countersunk hole provided in the face glass is fastened and fixed with a countersunk bolt and nut, and the tip side of the countersunk bolt is connected to the L-shaped mounting bracket with a bolt and a nut. Describes a structure in which a bolt is fixed to a rib glass with a bolt and a nut.
[0006]
[Problems to be solved by the invention]
However, if rocking occurs in each of the side glass plates arranged side by side due to an earthquake or the like, the surface glass and the rib glass are connected and fixed to each other by the L-shaped metal fittings. In addition, the glass plate is easily damaged.
[0007]
As the support structure of the glass plate that can cope with the occurrence of these interlayer displacements, for example, Japanese Utility Model Laid-Open No. 1-75509 is disclosed, and when the glass stand is inclined in the glass in-plane direction when an earthquake occurs, When the first mounting bracket tilts with respect to the glass stand and the second mounting bracket slides with the first mounting bracket, even if the glass stand tilts, this deformation force is applied to the surface glass. There is a configuration in which the glass is hardly transmitted and the surface glass is not damaged.
[0008]
However, in Japanese Utility Model Publication No. 1-75509, the movable mechanism including the projections of the metal fittings connecting the glass plates is exposed, and not only from the indoor side but also from the outdoor side through the transparent glass plate. Since it can be seen, it does not look good in appearance and is not preferable as a building using a transparent glass plate.
[0009]
[Means for Solving the Problems]
The present invention is intended to solve the above problems, that is, in a glass plate support structure using rib glass as a reinforcing material, even if the surface glass is subjected to a positive or negative wind pressure load from the out-of-plane direction, Further, it is intended that the glass plate is not damaged even when an interlayer displacement due to an earthquake or the like occurs, and that the appearance is slim and good in appearance.
