A description will be given with reference to FIGS. 1 to 7. In the first invention, a metal joint 1 composed of a body 1a having a hole 1c through which a bolt 4 is inserted through a flat plate and a wing 1b protruding from the body 1a is attached to a pillar 2 by a bolt 4. A fixing structure in which a horizontal member 3 such as a beam or a base is fixed to the wing portion 1b and fixed with a pin 5, and the hole 2c of the body portion 1a is fitted into the pillar 2. To form
The metal joint 1 is accurately and firmly fixed to the column 2.

According to a second aspect of the present invention, a metal joint 1 comprising a flat body 1a and a wing 1b protruding from the body 1a is fixed to a column 2, and a beam, a base or the like is attached to the wing 1b. A joint structure in which the horizontal member 3 is assembled and fixed with the pin 5, wherein the column 2 is formed with a fitting concave portion 2 b into which the body 1 a of the metal joint 1 is fitted, and the metal joint 1 is accurately and accurately inserted into the column 2. Be firmly fixed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the first invention is shown in FIG.
(A), shown in FIGS. 2 and 3 (a). In this joint structure, a metal joint 1 composed of a body 1a formed by projecting a hole 1c through which a bolt 4 is inserted into a flat plate and a wing 1b protruding from the body 1a is fixed to a column 2 by a bolt 4. And the wing 1
This is a joint structure in which a beam (horizontal member) 3 is attached to the b and fixed with pins 5. An assembling recess 2a into which the hole 1c of the body 1a fits is formed in the pillar 2, and the metal fitting 1 is accurately and firmly fixed to the pillar 2.

That is, the recess 2a previously assembled to the pillar 2 is
Is formed, the joining hardware 1 is connected to its body 1a.
By fitting the rear portion into the assembling concave portion 2a, it is possible to fix it at an accurate position. Further, by positioning the hole 1c in the mounting recess 2a, the metal joint 1 is firmly fixed without shifting from the column 2. Thereby, the strength of the wooden building part is kept high.

Incidentally, as shown in FIG.
Is set so as to fit into the hole 1c.
Thereby, the assembling of the bolt 4 and the joining hardware 1 is strengthened. FIG. 3B shows another embodiment of FIG. 3A. 1 (b) and 1 (c) show another embodiment of FIG. 1 (a).

FIG. 4A shows an embodiment of the second invention. This joining structure is composed of a flat body 1a and the body 1a.
This is a joint structure in which a metal joint 1 composed of a wing portion 1 b protruding from a is fixed to a column 2, a beam (horizontal member) 3 is attached to the wing portion 1 b, and fixed with a pin 5. Then, a fitting recess 2b into which the body 1a of the metal joint 1 is fitted is formed in the pillar 2, and the metal joint 1 is formed.
Is fixed to the column 2 accurately and firmly.

That is, in this joining structure, since the body 1a of the joining hardware 1 is fitted into the fitting recess 2b formed in the column 2, the mounting position of the joining hardware 1 can be accurately determined. . Further, the body 1a is inserted into the fitting recess 2b.
By assembling it inside, even if a large force acts, no displacement occurs, and it is possible to assemble the column 2 firmly. Thereby, the strength of the joining structure and the wooden building can be increased. FIGS. 4B and 4C show another embodiment of the metal joint 1 shown in FIG. 4A.

FIG. 5 shows various bonding hardware 1 and pillars 2 which can be used in the embodiment shown in FIG.
FIG. In each case, since the body 1a is assembled in the fitting recess 2b of the column, the assembly to the column 2 is strong. In addition, since each of these metal joints 1 has a structure that can be used upside down, it is excellent in usability.

As shown in FIGS. 6 and 7 (a) and 7 (b), the beam as the horizontal member 3 does not form a concave portion, and the joint 1 and the other joints 1 are not formed. Can be joined.

[0013]

According to the first aspect of the present invention, the metal joint 1 is fitted into the mounting recess 2a formed in the pillar 2 with the hole 1c of the body 1a and fixed with the bolt 4. 1 can be easily and accurately aligned, and can be firmly fixed. Thereby, the strength of the wooden building part is kept high.

In the second invention, the body 1a of the metal joint 1 is
Since the fitting 1 is to be fitted into the fitting recess 2b formed in the column 2, the fitting position of the metal joint 1 can be accurately performed, and the fitting 1 can be firmly assembled. Thereby, the seismic strength of the wooden building can be increased.
