DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column-beam joint structure of a wooden structure such as a building unit.

[0002]

2. Description of the Related Art For example, in a building unit comprising a wall panel and a floor panel as described in Japanese Patent Publication No. 58-30978, between columns of opposing wall panels in order to supplement the rigidity of the building unit. It is conceivable to bridge the beam and butt-join each of both end faces of the beam to each of the beam joining surfaces of each column facing each other.

By the way, in the conventional girder-small beam joining structure, when joining the end surface of the girder to the girder joining surface of the girder, a beam receiver is attached to the girder joining surface of the girder. Insert the small beam into the beam receiver from the front with respect to the beam-joining surface of the large beam, insert bolts into the bolt holes provided in the beam and the beam receiver, and connect the beam to the beam receiver. On the other hand, it is fixed in the longitudinal direction of the small beam.

[0004]

However, when the conventional large beam-small beam joint structure is converted to a column-beam joint structure, there are the following problems.

[0005] The method of attaching the beam to the beam joint surface of the column is limited only from the front direction to the beam joint surface. However, when a beam is bridged between the existing columns of the opposing wall panel, the distance between both columns is equal to the beam length, and the beam can only be installed from the side to the beam joint surface of the column. The mounting structure cannot be adopted.

[0006] The mounting position of the beam with respect to the beam receiver provided on the beam joint surface of the column is fixed at one point where the bolt holes provided in the beam and the beam receiver coincide with each other. Cannot be adjusted in the direction.

According to the present invention, in a building unit, a beam can be attached from the side to a beam joint surface of a column, and a beam attachment position to a beam receiver provided on the beam joint surface of a column is adjusted in the beam longitudinal direction. The purpose is to make it possible.

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided a wooden-structure column-beam joint structure for joining an end face of a beam to a beam joint surface of a column. A beam receiver fixedly cantileveredly supporting a bolt so as to protrude in a direction parallel to the beam joint surface of the column under the state of attachment to the column, and screwed to the bolt of the beam receiver. Te, a nut for fastening the beam to be inserted into the bolt in the beams receiving fixture, the holes provided in the beam and inserted into the bolt of the beam receiving fixture, said by screwing the nut on the bolt With the beam fastened to the beam receiver,
The beam is fixed in the longitudinal direction of the beam with respect to the column.
It has a fixing tool for fixing .

[0009]

According to a second aspect of the present invention, in the first aspect of the present invention, the fixing tool is further inserted into a bolt of a beam receiver together with the beam, and is fastened to the bolt together with the beam by a nut. It is made to become.

According to a third aspect of the present invention, in the first aspect of the present invention, the fixing tool extends over a column and a beam and is fixed to the column and the beam.

[0012]

According to the present invention, the following operations are provided. A bolt into which the hole provided in the beam is inserted is provided on the beam receiver attached to the column, and the bolt is fixed so as to protrude in a direction parallel to the beam joint surface of the column. The cantilever is supported. Therefore, the beam can be attached from the side with respect to the beam joint surface of the column.

Accordingly, when the distance between both columns is equal to the beam length, the beam can be attached from the side to the beam joint surface of the column so that the beam is bridged between the existing columns of the opposing wall panels.

The mounting position of the beam with respect to the beam receiver provided on the beam joint surface of the column is guided by bolts fixedly supported by the beam receiver. Function), and can be adjusted in the longitudinal direction of the beam within the range of holes provided in the beam.

After the above adjustment, the mounting position of the beam is fixed to the column in the longitudinal direction of the beam by nailing the fixture to the beam .
