Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building metal fitting, and more particularly to a building metal fitting for joining a vertical structural member and an overhanging structure.

[0002]

2. Description of the Related Art As a building, for example, Japanese Patent Publication No. 58-3
As described in Japanese Patent No. 0978, it is like a building of a frame wall construction method in which a face material is stretched over a frame to form a floor or a wall, and a plurality of building units including the floor and the wall are joined together. It is known for its wooden construction.

When a projecting structure such as a porch or eaves is attached to a vertical structural material such as a pillar in such a building, the projecting structure is generally formed by passing a bolt through the vertical structural material. It is joined.

[0004]

However, in the above joint structure, the load of the overhanging structure is concentrated on the bolt penetrating portion of the vertical structural member. Therefore, especially when the vertical structural member is made of wood, it is vulnerable to concentrated loads, and thus there is a problem that the load cannot be supported when the overhanging dimension of the overhanging structure becomes large or the weight increases.

The present invention has been made to solve the above problems, and provides a construction joining metal fitting that can easily support an overhanging structure without concentrating the load even if the vertical structural member is made of wood. It is intended to be provided.
