Description of the Related Art There have conventionally been various methods for mounting a plate-like body such as a glass plate as an outer wall of a building, but recently, the mounting is often performed without a frame, and a perforation provided in a corner portion of a so-called glass plate. The glass plate is clamped by a support fitting attached to the part, and the support fitting is fixed to a frame such as a structure. Above all, glass screen
The point support method using metal fittings is
In recent years, it has attracted attention and is being widely used. In this point supporting method, an H-shaped or X-shaped supporting bracket fixed to a frame supports and fixes a perforated portion provided at a corner of four adjacent glass plates. Although not limited to the support method, when a curtain wall is formed, when a load due to wind pressure or the like is applied in an out-of-plane direction, an excessive force is applied to the plate-like body, and interlayer displacement due to an earthquake or the like occurs, and the plate-like body is deformed. When the upper side and the lower side are pulled in opposite directions, an excessive force is applied, and the glass plate is easily broken. For this reason, various measures have been taken to prevent the glass sheet from being damaged even when an excessive force is applied due to an earthquake, wind pressure, or the like.

[0003] Usually, the support bracket is used for abutting corners of a plurality of plate-like bodies arranged vertically and horizontally. However, for a perforated portion of an upper side corner of the uppermost row of glass plates, a hanging portion is used. In order to follow the deformation caused by the load of the glass sheet to be lowered and the wind pressure load, measures to prevent breakage and improvements have been made.

For example, Japanese Unexamined Patent Publication No. Hei 5 (1995) -239878 discloses a mounting member which is attached to a plate-like member so as to intersect in the surface direction, and which is connected to the mounting member and supported vertically. In the supporting mechanism of the plate-shaped member comprising the hanging member to be mounted, the mounting member holds the mounting portion to the plate-shaped member on one side of the base portion for connecting the hanging member. A projecting cylindrical portion is provided on the other side, and an interposition material having a horizontal connecting member is formed so as to freely move forward and backward with respect to the tubular portion, and the suspending member is formed of the attaching member. On the pedestal portion opposed to the base portion, a hanging rod member having a vertical connecting member protruding from the central portion of the top plate portion separated therefrom is erected and a coil spring material is interposed. A support rod is positioned on the left and right of the suspension rod member, and is formed between the pedestal and the top plate. The mounting member and the suspending member are supported by a plate-like member that is orthogonally connected to the top plate portion and the base portion through the support rods that form and fix a fixed portion to the base portion. Alternatively, in Japanese Patent Application Laid-Open No. 8-74366, an upper edge portion of a first plate-like member is supported by a supporting member on a frame, and a second plate is provided on a lower edge portion of the first plate-like member. In the support structure of a plate-like member that supports a plurality of plate-like members by supporting an upper edge portion of the plate-like member and supporting the third plate-like member by the second plate-like member, A support structure for a plate-like member provided at two upper corners of a first plate-like member and supporting an external force in an out-of-plane direction of the first plate-like member and the weight of the plurality of plate-like members is disclosed. Have been.
