It is a schematic diagram which shows a modification.

As shown in FIG. 7, the unit building 1A transports the factory-built building units 10 to a local construction site, and installs the plurality of building units 10 on the foundation 2 in the horizontal and vertical directions. , Building unit 1 on the top floor
It is constructed by providing a roof 3 on top of the roof.

Hereinafter, the building unit 10 and the unit building 1
The configuration of A will be described. (Building Unit 10) (FIGS. 1, 2, 4, and 5) The building unit 10 is formed of a skeleton structure in which columns 11 and floor beams 12 are joined as shown in FIGS. The outer diaphragms 14 are welded to the column joints, which are the corners, of the floor beam frame 13 formed by framing the four floor beams 12 into a rectangular shape.
A column 11 having a circular cross section is inserted into the column, and an outer diaphragm 14 is welded to an arbitrary height position of the column 11 to have no ceiling beam.

As the pillar 11, a steel pipe or the like having a circular cross section can be used, and as the floor beam 12, a C-shaped steel or the like can be used. In the case of a pillar 11 made of a steel pipe or the like having a circular cross section, an end plate 11A is attached to upper and lower end faces thereof and welded.

The outer diaphragm 14 has a plurality of flat surfaces 21 and forms a polyhedron such as a regular octahedron, and has a column insertion hole 22 at the center. Then, two flat surfaces 21A and 21B of the plurality of flat surfaces 21 are formed as flat surfaces 21 to which two floor beams 12 intersecting each other are joined.
The intersection angle between A and 21B is a right angle. Further, other flat surfaces 21, for example, the other two flat surfaces 21C and 21D are used as building reference surfaces for a building such as providing an outer wall mounting member without joining the floor beam 12, and these flat surfaces 21C and 21D are used.
