Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braces that are obliquely attached to a rectangular space formed by a pair of upper and lower horizontal members such as girders, barrels, and bases and a pair of left and right columns. The present invention relates to a tightly-bonded reinforcing metal member for attaching and fixing a material, a column, and a bracing together.

[0002]

2. Description of the Related Art In the construction of a wooden house, a skeleton is formed by horizontal members such as girders, girders, and bases, and columns vertically provided to intersect these horizontal members. Then, diagonal members are obliquely inserted in the diagonal direction of the rectangular frame formed by the pair of upper and lower horizontal members and the pair of right and left columns.

Such a diagonal member is called a bracing, and has a function of preventing the rectangular frame from being distorted when it receives a horizontal force such as a wind pressure or an earthquake. In particular, since the wall with braces is the most effective part against external force, pay attention to the end joints (knot or joint structure) so that the braces work effectively. Must be paid for and well balanced.

[0004] Conventionally, a standard as shown in Fig. 5 has been established for the joint at the end of the wooden bracing pad. That is, as shown in FIG. 1 (A), the braces c for the horizontal members a and the columns b are used.
Put the end part of the large insertion (also called insertion. Insert the end part of the member into other member), and strike multiple nails diagonally,
Further, a rectangular plate-shaped metal plate d is nailed and fixed.

As shown in FIG. 1B, the end portions of the braces c are butted against the horizontal members a and the pillars b (simply abutment), and the braces plate e having a specially designed shape is horizontally mounted. The material a, the pillar b, and the side surface of the brace c are applied, and the bolts are tightened and fixed by nailing.

As shown in FIG. 1C, the end portion of the bracing c is slid into the cross member a (a type of slant inserted diagonally) and partially extended into a bottle (one tree). Part of the width is left and the other is cut out) to cut in the horizontal member a, attach it, and drive in a plurality of nails.

In addition, when the upper end of the brace on the first floor and the through column are not used, or when the upper end of the brace is not used as a joint between the mounting column and the horizontal member, a bracing plate as a joint metal is used, In addition, there are detailed criteria corresponding to various examples.

[0008]

As described above, the joints at the ends of the wooden braces c are formed by using a metal fitting such as an open metal fitting d or a bracing plate e, or by directly assembling without using a metal fitting. There are many specifications. In addition, as the joining hardware, a corner hardware formed in a T shape, a battledore bolt in which a flat plate and a bolt are integrated, a V-shaped chevron plate, and the like are used.

However, when a strong vibration beyond the imagination occurs, for example, in a recent large earthquake, and an extremely large amount of vertical shaking or rolling is applied to the house, the joint at the end of the wooden bracing can endure. There is a risk of disassembly. Then, the bearing wall using the braces loses its function and is at risk of collapse.

Further, recently, as a joint metal fitting for a three-story wooden house, a hole-down metal fitting (also referred to as a pulling metal fitting) is often used. Figure 6 shows this hole-down hardware K
Is an example using.

FIG. 1A shows a hole-down hardware K that tightly connects both a base g on a foundation f and a pillar c erected on the base g. That is, an anchor bolt h protruding from the upper surface of the foundation f has a mounting hole through which the anchor bolt h protrudes from the upper surface of the foundation f through the base g, and a nut is screwed into the bolt h to be tightly connected. .

The side surface of the hole-down hardware K is attached and fixed to the side surface of the column b using a hexagon bolt or a lag screw or the like. At the position where the side surface is attached, the lower surface has a predetermined gap (usually about 30 mm) with the upper surface of the base g, and the above-mentioned gap is set as a margin.

Although not shown here, since the base g is tightly connected to the foundation f by another anchor bolt,
The hole-down hardware K makes a strong bond between the foundation f and the pillar c and a strong bond between the base g and the pillar b.

As shown in FIG. 1B, a pillar b1 on the upper floor and a pillar b on the lower floor with respect to a girder (floor beam) i which is a horizontal member.
In order to connect 2 and 2, respectively, the hole-down hardware K of the same structure is used. In this case as well, the pillars b1, b
Make a tight bond with the clearances at the bottom and top of 2, respectively.

As described above, by using the hole-down hardware K, the horizontal members such as the base g and the barrel i and the columns b, b1 and b are used.
Stronger ties with No. 2 were obtained, and safety standards were improved.

However, the situation is different when the braces c are to be attached here. That is, as shown in FIGS. 7A and 7B, it is free to attach braces to the corners where the hole-down hardware K is not attached by the above-described connection. Even if the braces c are to be attached to the corners where the down hardware K is attached, they cannot be attached because of the presence of the metal K.

If the braces c can be provided in as many required portions as possible, the yield strength of the bearing wall can be increased. However, since the hole-down hardware K has already been used for tightly connecting the horizontal members and the pillars, it is impossible to tightly connect the braces c here, and it is still impossible to achieve sufficient proof strength enhancement.

The present invention has been made in view of the above circumstances, and an object of the present invention is to further secure the tight connection between a cross member such as a girder, a girder, and a base, a column, and a bracing, The present invention intends to provide a tightening and strengthening metal fitting capable of tightly strengthening the function of the metal fitting in place of the hole-down hardware, while sufficiently strengthening the proof strength.
