In order to achieve the above object, the brace structure of the present invention has an upper side member and a lower side member that are parallel to each other, and left and right side members that are parallel to each other. A frame assembly formed in a polygonal frame that makes a right angle, and a bracing connection hole in each side of the octagonal metal frame
And a connecting fitting arranged in the space of the shaft assembly.
And one end part is inserted into the connection hole and fixed to the connection fitting, and the other end part is fixed to the upper side member and the lower side member of the shaft assembly, and one end part is A left-right brace in which the other end is fixed to the left and right side members of the shaft assembly while being inserted into the connection hole and fixed to the connection fitting, and one end is connected to the connection hole. And is fixed to the connecting metal fitting, and the other end is fixed to the beam member or the base through the oblique side member provided between the upper side member and the lower side member and the left and right side side members. It is composed of diagonal braces.

Since the connecting fitting is formed in an octagonal shape as described above, a plurality of braces provided in the space of the shaft assembly can be easily positioned in the vertical direction, the horizontal direction and the diagonal direction to be assembled. You can

Further, in the shaft assembly, the left and right side members and a hypotenuse member continuous to both ends of the side member are integrally formed, and both ends of the upper and lower side members are ends of the hypotenuse member. If it is configured to be detachably connected to the part to form an octagonal frame, the frame assembly can be disassembled and transported, and can be easily assembled at a construction site. In this case, it is preferable that the shaft assembly is made of a metal square pipe material.

Further, the bracing structure according to the present invention can be applied to a rectangular frame assembly. In this case, the diagonal brace is fixed to the left and right side members, or penetrates the left and right side members and is fixed to the beam or the base.
