Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a unit building.

[0002]

2. Description of the Related Art A conventional unit building is disclosed in
As described in JP-A-268964, there is known a so-called overhang structure in which an auxiliary unit is attached to an upper-floor building unit by protruding outward from an outer wall surface. In the unit building described in the above publication, a stud is attached to the building unit, and an auxiliary unit is attached to this stud, so that an auxiliary unit other than the auxiliary unit having substantially the same width as the interval between the pillars can be attached. . Further, even if the auxiliary unit is mounted on the girder surface of the building unit, it is mounted on the construction site, so that the transportation of the building unit is not restricted by the Road Traffic Law or the like.

Further, as described in Japanese Patent Application Laid-Open No. 8-13619, a mounting bracket is provided in advance on one of the auxiliary unit and the building unit (auxiliary unit), and the other of the auxiliary unit and the building unit at the construction site. The (building unit) is mounted on a mounting bracket, so that the auxiliary unit can be easily mounted. Further, since the mounting bracket has a plate member extending in the vertical direction and a reinforcing piece joined to the plate member and extending in the horizontal direction, the strength against a lateral load can be increased.

[0004]

However, in the unit building described in Japanese Patent Application Laid-Open No. 7-268964, the pillar of the building unit and the pillar of the auxiliary unit are directly butted with a spacer interposed therebetween, and are bolted or the like. Since it is fixedly mounted, there is a problem that it takes time and effort to perform mounting work in which the position is adjusted vertically and horizontally. Further, according to the mounting structure of the auxiliary unit described in JP-A-8-13619, the mounting operation of the auxiliary unit is easy and the strength against the lateral load can be increased, but the frame structure of the auxiliary unit is composed of columns and beams. Since it is merely assembled in a box shape, there is a problem in strength against a vertical load and a torsional load. In particular, when the auxiliary unit is mounted on the girder surface of the building unit, the size of the auxiliary unit increases, which causes a problem in strength.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to increase the strength of an auxiliary unit with respect to a vertical load and a torsional load, and to facilitate the mounting operation. It is to provide a simple unit building.
