Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure of a frame mainly composed of a horizontal member and a vertical member or another horizontal member orthogonal to the horizontal member in a wooden house building.

[0002]

2. Description of the Related Art A frame composed of a horizontal pillar (horizontal member) and a vertical pillar (vertical member) orthogonal to the horizontal pillar in a wooden building is connected by a mortise portion interposed between joint surfaces. At the same time, it is reinforced by wooden fires strung between the columns and braces. However, with such wooden fire and braces, it takes a lot of time and labor for construction, such as the need to penetrate nails and bolts diagonally against fire, etc., and it is inferior in rigidity, especially for vertical and horizontal vibration due to an earthquake. I can't stand it.

Conventionally, for example, Japanese Patent Laid-Open No. 5-311743.
There is known a flint metal article as described in Japanese Patent Publication No. In this flint metal fitting, triangular reinforcing pieces are continuously provided at the corners of a substantially L-shaped metal body formed by bending a metal plate at a right angle, and both end sides of the L-shaped metal body are used as abutting pieces. The contact pieces are fixed to the side surfaces of both the vertical and horizontal columns with bolts. However, in such a struck metal, although the triangular reinforcing piece is provided at the corner of the L-shaped metal body, its outer end side is a free end and is not reinforced at all. Due to the intense lateral or vertical load that is momentarily applied to the frame when it occurs, the above L
There is a risk that the outer end portion side of the character-shaped hardware body may be bent from the boundary portion with the reinforcing piece.

In view of the above-mentioned circumstances, the present invention can form a rigid frame structure that can sufficiently withstand the strong lateral load and vertical load acting on the frame when an earthquake occurs, and is easy to install. An object of the present invention is to provide a framework fixing structure that can significantly reduce the cost.
