Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a column and a beam constituting a frame body of a building unit or the like.

[0002]

2. Description of the Related Art Generally, a unit house is constructed by connecting a plurality of building units. Further, in this building unit, a plurality of pillars extending in a substantially vertical direction are connected by a plurality of beams extending in a substantially horizontal direction to form a rectangular parallelepiped shape or the like.

The connection between the column and the beam is performed by welding the end of the beam to the side surface of the column.

Incidentally, as another joint structure of columns and beams, for example, Japanese Utility Model Publication No. 57-124508 and Japanese Utility Model Publication No. 58 are available.
There is one such as that described in Japanese Patent Laid-Open No. 183805.

[0005]

However, in such a conventional one, in order to fix the column at a predetermined position with respect to the beam, it is necessary to carry out welding while holding the beam of the heavy object. No, this work was difficult. Further, when the welding position of the beam is displaced, it is difficult to readjust it.

[0006] Therefore, an object of the present invention is to provide a column-beam joint structure which can improve the workability of attaching the beam and can easily adjust the position.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a bracket is fixed to a column extending in a substantially vertical direction, and an end portion of a beam extending in a substantially horizontal direction is attached to the bracket. In the joint structure of the pillar and the beam, a mounting surface portion is formed on the bracket along the longitudinal direction of the beam, and the mounting surface portion or the long hole of the beam is formed on the mounting surface portion of the beam through a long hole formed in the beam. The end portion is attached by screwing or riveting, and the elongated hole has a joint structure of a column and a beam that are formed long in the longitudinal direction of the beam.

[0008]

[Operation] According to this means, the bracket is fixed to the pillar in advance. From this state, the end portion of the beam is screwed to the mounting surface portion of the bracket through the long hole. In this case, the beam is slid in the longitudinal direction through the long hole to adjust the position, and then completely fixed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention.

First, the structure will be described. In the figure, reference numeral 1 is a pillar extending in a substantially vertical direction of a building unit, and an end portion 4 of a beam 3 extending in a substantially horizontal direction has a bracket 5 on an upper end portion 2 of the pillar 1. It is adapted to be attached by means of high tension bolts 6 and nuts 7 through.

As shown in FIG. 3, the bracket 5 has a fixed surface portion 8 which is fixed to the side surface portion 2a of the column upper end portion 2.
And a mounting portion 9 projecting laterally from here.
The mounting portion 9 has a U-shaped cross section along the vertical direction,
It has an upper mounting surface portion 9a, a lower mounting surface portion 9b, and a side mounting surface portion 9c.

On the other hand, the beam 2 has a U-shaped cross section and is fitted in the mounting portion 9 of the bracket 5.

Two long holes 10 are formed in each of the upper and lower mounting surface portions 9a and 9b of the bracket 5, and a total of four long holes 10 are formed in the side mounting surface portion 9c. .. These elongated holes 10 are formed long in the longitudinal direction of the beam 3.

A circular insertion hole (not shown) into which the bolt 6 is inserted is formed in the end portion 4 of the beam 3 at a position corresponding to the elongated hole 10.

Next, a method of attaching the beam 3 will be described.

In advance, on the side surface portion 2a of the upper end portion 2 of the pillar 1,
The fixed surface portion 8 of the bracket 5 is fixed. From this state, the beam 3 is inserted in the U-shaped mounting portion 9 of the bracket 5.
Insert the end 4 of the.

Then, the end portion 4 of the beam 3 is temporarily fixed to the bracket 5 through the elongated holes 10 and the like with a plurality of bolts 6 and nuts 7. After that, the beam 3 is slid in the longitudinal direction through the long hole 10 to adjust the position, and the bolt 6 and the nut 7 are completely tightened.

Since the bolts 6 and the nuts 7 are temporarily fixed in this manner, the workability is good without holding the beam as in the conventional case. In addition, the elongated hole 10 enables position adjustment and can be securely fixed at a predetermined position.

Although the embodiment of the present invention has been described with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. However, it is included in this invention. For example, although the bolts 6 and the nuts 7 are used in the above-described embodiments, rivets or the like may be used, and the elongated holes 10 may be formed in either columns or beams.

[0021]

As described above, according to the present invention, the bracket has the mounting surface portion along the longitudinal direction of the beam, and the mounting surface portion or the long hole formed in the beam. The end of the beam is attached by screwing or riveting via the, and since this elongated hole is formed long in the longitudinal direction of the beam, the workability of attaching the beam can be improved and the position adjustment can be performed. Can be done easily,
It has a practically useful effect.
