DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a brace reinforcing metal fitting for reinforcing a brace of a built-in house.

[0002]

2. Description of the Related Art Conventionally, various types of reinforcing brackets have been proposed. For example, Japanese Utility Model Laid-Open Publication No. 64-41503 discloses fixing brackets mounted at four corners formed by a base, a girder, and a column, and fixed at diagonal lines. Brace fittings have been proposed in which two kinds of metal pipes are connected by screws and the fittings are tied with a brace whose length can be adjusted.

[0003]

Since the above-mentioned brace fitting is composed of a pipe provided with a thread, a pipe threaded with a female thread, and a mounting plate welded to their free ends, the above-mentioned bracing metal fitting is required. If one of the mounting plates is not removed, the length cannot be adjusted, and it may take time to attach the brace bracket.Therefore, the structure of the brace bracket that connects the threaded rod with a so-called turnbuckle Is complicated and difficult to operate, and the fixing brackets located at the four corners are fixed only to the base and pillars and the columns and eaves girders, and they are not connected to each other in the horizontal and vertical directions. When either the eaves girder or the column shrinks, an excessive force is applied to the turnbuckle, and there is a problem that the strength is not always sufficient.

[0004]

According to the present invention, there is provided a corner fitting mounted on each of four inner corners where a pair of pillars erected at a predetermined distance between a base and a girder and the base and the girder intersect at right angles, The upper surface of the base located between the columns and the columns, the lower surface of the girder located between the columns and the columns, and the corner fittings attached to the inside of each of the pair of columns and attached to the four corners are horizontally and vertically mutually. A connecting metal fitting formed in two directions, two braided flat iron plates which are disposed to cross over the diagonal lines of the four corners and tighten the corner metal fittings of the four corners to each other, and are formed by the lower ends of the flat iron plates, the base, and the columns. And a length adjustment member that is interposed between the corner fittings located at the corners to be adjusted and adjusts the length of the two in the longitudinal direction. No It is intended to provide a brace reinforcing bracket which can overcome consent to advance.

[0005]

As described above, according to the present invention, the corner fittings attached to the inside of each of the four corners formed by the base, the girder, and the column are firmly tightened in the horizontal and vertical directions by the above-mentioned connecting fittings. The corner fittings located are crossed and tightened by brace flat iron plates, and the lower end of each of the brace flat iron plates and the corner fittings located on the base are connected and connected by a length adjusting member, and the base, the girder and the column are connected. Are firmly fixed inside them.
