DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagonal member to be installed at a diagonal position of a rectangular wall frame formed by columns and horizontal members (beams, bases, etc.) in a wooden building, that is, a brace. The present invention relates to a binding structure and a combination of the metal fitting and a bolt row plate.

[0002]

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.

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.

[0004]

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 contacting / separating or rubbing operation with respect to the side surface of the pillar 3 and the upper surface of the base 4. The brace 1 has a cut end surface 2 ', 2 "which is a transverse end surface in a direction intersecting with the fiber running direction of the wood. Since the toughness is stronger due to the side surface of the pillar 3 and the upper surface of the base 4 in the forward direction of the fiber running direction of the wood, by repeating the above-mentioned contact or sliding and separating operation, the brace 1 Of the end 2 of the wall, the resistance against the horizontal force of the wall surface by the brace 1 is reduced. This means that in the event of an earthquake or the like, the swing of the wooden building is promoted and may cause damage.

Accordingly, the present invention provides a brace which receives a compressive force by allowing the end of the brace to be tied to the corner without directly joining the opening of the brace to the side surface of the pillar or the upper surface of the base. The end of the wooden building does not bite into the side surface of the pillar or the top surface of the base even if it is subjected to a tensile force, and the shaking of the wooden building is promoted or damaged even in an earthquake or the like. It is something that has not been done.
