DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the mounting of a plate-like body constituting a curtain wall to a wall surface of a support bracket, and more particularly, to the mounting in a direction outside the plane even if the distance between the plate-like body and the mounting wall surface is small. Provided is a mounting structure for a support bracket that can be adjusted in position.

[0002]

2. Description of the Related Art Conventionally, there are various methods for mounting a plate-shaped body as an outer wall of a building, but in recent years, such mounting is often performed without a frame, and is performed by attaching a plate-shaped body to a perforated portion provided at a corner of the plate-shaped body. The supporting member is sandwiched between the plate members, and the supporting member is attached and fixed to a frame such as a structure. In particular, a point support method using a metal fitting has been attracting attention in recent years as a method of forming a glass screen, and is being widely used. This point support method uses H fixed to the frame.
The corners formed by four adjacent glass plates are supported and fixed by supporting brackets in the shape of a letter, an X-shape or the like.

Further, as shown in Japanese Utility Model Laid-Open Publication No. 3-113037, in mounting a wall mounting support, a bolt fixed to a wall and at least up, down, left and right with respect to the bolt to be inserted. A substantially L-shaped wall mounting support having a through hole that allows free movement of the bolt, and a projection that can lock a washer material, and an oblique hole through which the bolt material is inserted. To the wall surface of the wall-mounting support bracket, which is composed of a washer member having a nut and a nut member, and is positioned and fixed by the nut member through the through hole of the support member with the bolt member and the oblique hole of the washer member. Is described.

[0004] Further, Japanese Patent Application No. 6-3 filed earlier by the present applicant.
No. 01823 describes a centering method for mounting the glass plate support bracket to the structural frame. This method includes a connection bracket fixed to a wall surface and a screw hole provided at the center of the connection bracket. The adjustment bolt is provided at the bottom of the hollow cylindrical adjustment bracket with an adjustment bolt and is screwed and fixed through an elongated hole that can move up, down, left, and right, and adjustment in the up, down, left, and right directions is described. It describes that the adjustment in the out-of-plane direction is performed by screwing a support fitting provided with a projection at the center into a screw hole provided on the inner surface side of the hollow cylindrical shape of the fitting.

[0005]

When the plate is attached to the side wall of the building by the support bracket, the upper and lower sides of each plate are placed so that the whole of the plurality of attached plates becomes a flat surface. It is necessary to adjust the horizontal direction and the out-of-plane direction.

In the structure disclosed in Japanese Utility Model Laid-Open Publication No. 3-13037, a structure is provided for adjusting and absorbing an error in the mounting position of a support bracket so that a bolt material fixed to a wall surface can move freely in the vertical and horizontal directions. An L-shaped wall mounting support having a hole, and a nut member via a washer having an oblique hole, which is fastened and clamped by a nut material to fix the wall mounting plate in an out-of-plane direction. There is a problem that adjustment is not possible. In addition, there is no aesthetic problem when the wall mounting plate is opaque and the support bracket is hidden, but when supporting a transparent glass plate, bolts protruding from the wall surface, the substantially L-shaped support bracket, etc. are exposed. However, there is a problem that the appearance becomes unsightly and unfavorable.

[0007] Japanese Patent Application No. 6-301823 is used when the distance between the support bracket and the frame is large, and is used when mounting the glass plate support bracket to the structural frame. A method of centering in the direction is mainly disclosed, and adjustment in an out-of-plane direction can also be performed by screwing a projection of a support fitting into a hollow cylindrical internal screw hole of the adjustment fitting. Although it is possible to adjust to some extent out of plane by the depth of screwing, H-shaped or H-shaped as a four-point support fitting used at the intersection of the corners when multiple glass plates are installed vertically and horizontally. Because of the shape of the X-shape etc., it is allowed only at the position where the four-direction tip of the support bracket comes to the perforated part of the corner of the glass plate,
In addition, since it is necessary to weld and fix the adjusting bracket and the receiving bracket after the adjustment in the up, down, left, and right directions, there is a problem in the case where the distance between the plate-shaped body and the wall surface is small as in the present invention.

[0008]
