BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 shows an embodiment of a joint structure for a wooden building according to the first invention. This is because the anchor bolt 5 embedded in the foundation 6 is assembled by fastening the body portion 1a of the T-shaped hardware 1 in which the wing portion 1b is erected from the center portion of the body portion 1a with the nut 11, and assembling the first floor pillar 7a. The T-shaped concave portion 3 having a shape corresponding to the T-shaped metal 1 is formed at the lower end of the. Then, the T-shaped metal 1 is fixed to the first floor pillar 7a by the pin 12 in a state where the T-shaped metal fitting 1 is entirely fitted in the T-shaped recess 3, and the foundation 6 and the first floor pillar 7a are joined. The pin 12 is inserted into the hole formed in the first-order pillar 7a and the hole formed in the wing portion 1b of the T-shaped metal fitting 1, thereby fixing the first-order pillar 7a to the T-shaped metal fitting 1. Is.

In this embodiment, the T-shaped metal 1 is used, but instead of the T-shaped metal 1, a U-shaped metal 2 having wing portions 2b erected from both ends of the body 2a is used. be able to. In this case, a U-shaped concave portion 4 into which the entire U-shaped metal piece 2 can be fitted is formed at the lower end portion of the first floor pillar 7a. The same T-shaped metal 1 or U-shaped metal 2 can be used to join the foundation 6 and the pillar 7c.

In the first aspect of the present invention, the foundation 6 and the pillar 7 (first floor pillar 7a or through pillar 7c) are joined by inserting the T-shaped metal article 1 or the U-shaped metal article 2 into the T-shaped recess 3 or the U-shaped recess 4. Since it is supposed to be done by doing so, the work becomes easy. In addition, since the T-shaped metal fitting 1 and the like made of metal and having high rigidity are used,
It is possible to strengthen the connection between the foundation 6 and the pillar 7, and it is possible to provide a wooden building having excellent earthquake resistance. Since the T-shaped recess 3 and the U-shaped recess 4 are small, the strength of the pillar 7 is not weakened. Further, since the T-shaped concave portion 3 and the U-shaped concave portion 4 have a constant shape corresponding to the T-shaped metallic article 1 and the U-shaped metallic article 2, they can be mechanically and easily formed not in the field but in the factory. Productivity can be improved.

Further, it should be noted that in the T-shaped metal 1 or the U-shaped metal 2, not only the blade portions 1b and 2b but also the body portions 1a and 2a are fitted into the T-shaped concave portion 3 or the U-shaped concave portion 4, respectively. Therefore, like the wings 1b and 2b, the trunks 1a and 2
It is also possible that a can be surely assembled to the first-floor pillar 7a, and by this, the joint between the foundation 6 and the first-floor pillar 7a can be further strengthened. That is, in the T-shaped hardware 1, its wing portion 1b fits into the slit portion 3a of the T-shaped recess 3 and the body portion 1a fits into the opening step portion 3b, and only the wing portion 1b fits into the slit portion 3a. This is because the contact area is larger than that in the case of assembly. Similarly, in the U-shaped metal product 2, the blade portion 2b fits into the slit portion 4a of the U-shaped recess 4 and the body portion 2a fits into the opening step portion 4b, so that the blade portion 2b is stably and firmly assembled in a wide contact area. Because.

FIG. 2 shows a first embodiment of a joint structure for a wooden building according to the second invention. This is because the body 1a of the T-shaped metal 1 having the wing 1b standing upright from the center of the body 1a is attached to the side surface of the first floor pillar 7a with the bolt 10 and the nut 11, and the base 8a which is the horizontal member 8 or A T-shaped concave portion 3 having a shape corresponding to the T-shaped metal article 1 is formed at the side end portion of the large pull 8b. Then, the T-shaped metal fitting 1 is fixed to the base 8a in a state where the T-shaped metal fitting 1 is entirely fitted in the T-shaped recess 3, and the first floor pillar 7a and the base 8a are joined. It should be noted that instead of the T-shaped hardware 1, the U-shaped hardware 2 in which the wing portions 2b are erected from both ends of the body portion 2a is used.
A U-shaped recess 4 is formed in place of the mold recess 3, and the U-shaped metal article 2 is U-shaped.
It can also be fitted and fixed in the mold recess 4.

Further, the T-shaped hardware 1 and the U-shaped hardware 2 have body parts 1a and 2a.
Similarly, since the blades 1b and 2b are fitted and fixed in the T-shaped concave portion 3 and the U-shaped concave portion 4 as well, the column 7 and the horizontal member 8 can be joined more firmly.

FIG. 7 shows a first embodiment of the wooden building according to the third invention. This is from the center of the body 1a to the wings 1.
The body part 1a of the T-shaped metal fitting 1 in which b is erected is attached to both the upper and lower surfaces of the beam 8c which is the horizontal member 8 and the body difference 8d.
A T-shaped recess 3 having a shape corresponding to the T-shaped metal article 1 is formed at the upper end of a and the lower end of the second floor pillar 7b. And
The T-shaped metal 1 is fixed to the first-column 7a and the second-column 7b in a state where the entire T-shaped recess 3 is fitted in the T-shaped recess 3, and the horizontal member 8 is joined to the first-column 7a and the second-column 7b.

Also in the third invention, the T-shaped metal article 1
Instead of U, the wing portion 1b is erected from both ends of the body portion 2a.
The mold piece 2 can be used, and the U-shape piece 2 can be fitted into the U-shaped recess 4 and joined together.

A second embodiment of the third invention is shown in FIG.
This is the upper surface of the base 8a or the horizontal pull 8b which is the horizontal member 8,
Assemble the T-shaped hardware 1 on both the lower surface of the beam 8c and the body difference 8d,
The T-shaped hardware 1 is formed on both upper and lower ends of the first-floor pillar 7a.
It is fitted in the mold recess 3 and fixed, and the first-order pillar 7a is joined between the base 8a (large pull 8b) and the beam 8c (body difference 8d).

A third embodiment of the third invention is shown in FIG.
This is, in addition to the second embodiment shown in FIG. 8, a T-shaped recess 1 in which the T-shaped metal 1 is assembled on the upper surface of the beam 8c or the body difference 8d and the T-shaped metal 1 is formed at the lower end of the second floor pillar 7b. 3 is fitted and fixed, and the beam 8c (body difference 8d) and the second floor pillar 7b are joined.

According to the third aspect of the invention, since the T-shaped metal fitting 1 and the like are fitted into the T-shaped recess 3 and the like to join the horizontal member 8 and the pillar 7, the work at the site can be facilitated. be able to. Moreover, since the T-shaped metal 1 or the like made of metal and having high rigidity is used, the horizontal member 8 and the pillar 7 can be joined firmly. Since the T-shaped recess 3 and the U-shaped recess 4 are small, the strength of the horizontal member 8 is not weakened. Further, since the T-shaped concave portion 3 and the U-shaped concave portion 4 have the shapes corresponding to the T-shaped metallic article 1 and the U-shaped metallic article 2, they can be mechanically formed in a factory, and therefore, the work on the site becomes easy. . Furthermore, the T-shaped hardware 1 and the U-shaped hardware 2 are
