Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for a steel pipe column exterior material, which is used as a base material and a receiving member for the exterior material when mounting an exterior material such as a corner ALC block around a steel pipe column.

[0002]

2. Description of the Related Art For example, when mounting a corner ALC block as an exterior material around a square steel pipe column, conventionally, as shown in FIG. 8, a bracket 20 is directly welded to the square steel pipe column 10 or a steel frame beam is used. The receiving member is attached to another member extended to the corner by welding or bolting, and the ALC block for corner is attached to the receiving member. When the corner ALC block is connected to the receiving object, the corner ALC block is directly stopped by a long screw from the outer surface of the corner ALC block, or a hole of a predetermined size is made in the corner ALC block and the hole is received in this hole. A bolt protruding from the metal object is inserted, and a nut ALC block is fastened to the metal object by a nut.

[0003]

However, although the conventional metal receiving object 20 is directly welded to the steel pipe column 10 as described above, in recent years, the number of welding workers is small and the number of workers is secured. In addition, it is difficult to perform such work at the construction site, and there are many work at high places using scaffolding, and there are problems such as being easily affected by weather, especially humidity. There was a problem that high precision welding could not be performed.

Further, even if welding is carried out in a factory in order to avoid welding work at a construction site, there is a problem that the receiving object protruding from the steel pipe column may be damaged before being brought to the construction site after welding. there were.

Further, in the structure in which the receiving object is bolted to another member extending from the steel beam to the corner portion, the distance from the steel beam to the receiving object is long, and an extra force is applied between them, so that the extension portion There was a problem that it was necessary to take secondary measures such as increasing the wall thickness of the.

Therefore, an object of the present invention is to provide a bracket for a steel pipe column exterior material which can be easily attached to a steel pipe column by anyone without welding.

[0007]

According to the present invention, when mounting an exterior material on the outer surface of a steel pipe column, a plurality of metal fitting elements are respectively connected by a connecting tool to surround the steel pipe column and used as a receiving member for the exterior material. A metal fitting for an exterior material, wherein each of the metal fitting elements has a protrusion on its inner surface that fits into a locking hole formed in the steel pipe column, and has a bent portion at each connection end. The above-mentioned object is achieved by providing an external bracket for a steel pipe column, characterized in that the above-mentioned connecting tool has a holding portion that fits into the bent portions of the adjacent connecting ends to hold each of the bent portions. It was done.

[0008]

According to the present invention, when the exterior material is attached to the outer surface of the steel pipe column, the projections on the inner surface of the metal element are fitted into the locking holes of the steel pipe column to attach the plurality of metal element to the steel pipe column. The bending parts can be clamped and fixed by the holding part of the connecting tool only by inserting the connecting tool into the bending parts of the adjacent metal fitting elements.
