る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagonal material for a wooden building, which is to be incorporated at a diagonal position of a rectangular wall frame formed by columns and horizontal members (beams, bases, etc.), that is, a wooden building. The present invention relates to a bracing structure and braces for objects.

うにすることは既に知られている。2. Description of the Related Art In a wooden building, as shown in FIGS. 8 and 9, an end 2 of a brace 1 is attached to a corner formed by a pillar 3 and a horizontal member 4 such as a base 4. A required fastening member 5 is installed at the corner, and a mounting wall 6 of the fastening member 5 is provided.
It is already known to fasten the end 2 of the brace 1 with bolts and nuts.

直接接合させている。The above-mentioned tying fitting 5 is installed on one half of the center line L of the width of the column 3 and the base 4, and the end 2 of the brace 1 is positioned on the other half of the center line L. Brace 1
Of the end portion 2 (transverse end surface in the direction intersecting with the fiber running direction of the wood) 2 ', 2 "are directly joined to the side surface of the pillar 3 and the upper surface of the base 4.

摺擦動作を繰り返すものである。The brace 1 receives a compressive force or an opposite tensile force depending on the direction in which a horizontal force acts in an earthquake or the like. Repeats the contact / separation or rubbing operation between the side surface of the pillar 3 and the upper surface of the base 4.

らすおそれがあることを意味する。The open ends 2 'and 2 "of the brace 1 are transverse end faces in the direction intersecting the running direction of the fiber of the wood, and are more tough due to the side surfaces of the pillar 3 and the upper surface of the base 4 which are forward in the running direction of the fiber of the wood. As a result, the end 2 of the brace 1 bites into the side surface of the pillar 3 or the upper surface of the base 4 due to the repetition of the above-mentioned contact and separation or rubbing operation. This means that, in the event of an earthquake or the like, shaking of the wooden building is promoted, which may cause damage.

ある。[0006] Although the tying fitting 5 itself is installed on one side half of the center line L of the width of the column 3 and the base 4, the end 2 of the brace 1 is connected to the other half of the center line L. When the floor plate (not shown) is to be erected on the other half of the base 4, the brace 1 becomes an obstacle and the floor plate cannot be erected near the upper surface of the other half of the base 4, Therefore, the floorboard must be stretched at a position above the base 1 at a distance. For this reason, there is a disadvantage that the height from the floor of a certain floor of the building to the floor immediately above it, that is, the floor height cannot be set large.

An object of the present invention is to provide a bracing structure and a metal fitting for a wooden building in which the floor height can be set to be large so that the building can be erected.
