SUMMARY OF THE INVENTION The present invention uses a metal joint which is bent at a right angle to a connection portion of a wooden building and has a steel pipe inserted into a pillar or a beam or the like fixed to one of the bending plates. Thus, the column, the beam, and the like, and the joining hardware are integrally tightened and fixed with bolts, thereby ensuring the integration and solving the conventional problem.

That is, the present invention is directed to a joint device in which a joint bent at a right angle is fixed to a connecting portion such as a column and a beam, and a steel pipe inserted into a column or a beam is fixed to one of the refraction plates of the joint. Then, bolts are fixed to both ends of the steel pipe, respectively,
The joint metal, the pillar, the beam and the like are fixed, and the bracing fixing metal is fixed by bolts for fixing the joint metal.

Further, the invention of the integrated structure is a structure in which a pillar and a beam and the like are integrated by fixing a joint metal bent at a right angle to each connecting portion between a through pillar and a beam or the like of a wooden three story building. A steel pipe to be inserted into a column or a beam or the like is fixed to one of the refraction plates of the metal joint, and bolts are fixed to both ends of the steel pipe, respectively, so that the column, the beam or the like, and the metal joint are integrally formed. The bracing fixture is fixed by bolts for fixing the joining hardware.

Further, the invention of the metal joint is to insert a fixing bolt into the inside of both ends by inserting the one refracting plate of the metal joint bent at a right angle into a contact surface such as a column or a beam into the column or the beam. A steel pipe provided with a thread for joining is implanted, and the length of the steel pipe is a length that does not penetrate columns and beams, etc., and is a length that can be screwed with the required strength of the fixing bolt It is.

[0009] The length of the steel pipe in the above-mentioned invention must have a sufficient bolt tightening margin without penetrating columns or beams or the like, and also have a sufficient screwing length between the bolt and the steel pipe. Therefore, a relatively long bolt is preferable as long as the bolt has a tightening margin.

[0010] The above-mentioned metal joints need to have sufficient rigidity not to be deformed as well as being able to withstand the external force applied to the connection.

The beams and the like in the present invention are horizontal members such as beams and girders, and are members that form joints with columns.

In the present invention, the bent plate of the metal joint and the steel pipe are welded and fixed to be integrated.
