Abstract

PROBLEM TO BE SOLVED: To prevent movement of a mounting hole for an extended support arm to enhance operability by supporting a boring part against the mounting hole, providing a wide key groove in a shank, making a locking screw abut to the diagonal side wall of the groove, and thus avoiding rotation of the shank. SOLUTION: One end of a connecting member and the shank 5 of a support metal fitting are screwed to a rod which is secured horizontally from a structure to the backs of the abutting parts of plates attached to the vertical and horizontal sides of a curtain wall. Mounting holes 4, 4 are installed at the ends of support arms 3, 3 extending in four directions from the shank 5 of the support metal fitting, and arm ends 13, 13 are fastened into place by nuts from both sides of the mounting holes 4, 4. Opposite key grooves 6, 6 are provided in the shank 5 of the support metal fitting, and locking screws are advanced until abutting the key grooves 6, 6, thereby securing the connecting member to the shank 5. Thus even if moment caused by localized load caused by the attached and unattached parts of a plate works on the support metal fitting, construction work can be achieved smoothly in a short time.

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 support method, corners formed by four adjacent glass plates are supported and fixed by H-shaped or X-shaped support fittings fixed to the body.

Since the moment due to the unbalanced load due to the balance acts on the support bracket, and the support bracket rotates around the shaft, the mounting hole at the end of the support arm extending in all directions of the support bracket and the drilling position of the plate-like body are slightly shifted. In some cases, the installation work does not go smoothly and it becomes difficult.

であった。[0006] This is a key groove provided in the shaft of the support bracket,
This is because there is a slight gap between the outer diameters of the fixing screws, and a slight rotation of the shaft causes a large displacement at the mounting hole at the tip of the support arm. Work had to be performed, and workability was poor.
