Abstract

PROBLEM TO BE SOLVED: To provide a building unit, which can be reinforced by simpler structure without using a sub-frame and which does not disturb a planning. SOLUTION: In the one-storied building unit, joining sections 30 are installed to longer side floor beams 14 arranged between two corners, and the joining sections 30 are also joined with a foundation. Accordingly, rigidity in the periphery of the joining sections 30 of the building unit 10, the rigidity of the plane of a structure, can be increased. Thus, the building unit 10 can be reinforced by simple structure without using a conventional sub-frame. Since the sub-frame is not used, not only a limitation on a plane planning such as a floor plan design can be eliminated but also cost can be reduced, and the unit type building can be provided at a low cost.
