As shown in FIG. 8, this building unit 1 has four pillars 2 erected at four corners and four upper beams 3 and lower beams connecting the upper ends and the lower ends of these pillars 2 to each other. 4 is provided, and a ceiling small beam 6 is provided between the upper beams 3 on the long side, and a joist 7 is provided between the lower beams 4 on the long side. I have. Then, a ceiling surface material, a floor surface material, an outer wall, an inner wall, and the like are attached to such a frame 5.

[0003] In some cases, such a unit-type building is built on a cast-in-place concrete frame (hereinafter referred to as an RC frame) such as RC (reinforced concrete), for example, in relation to the site. The upper surface of the RC gantry is made flat, and at least one side is often opened, and the inside is used for, for example, a garage.

[0004]

In a unit-type building built on such an RC frame, since the upper surface of the frame is flat, a general foundation having a predetermined height from the ground surface to the upper surface is required. In contrast, the dimension between the upper surface of the gantry and the floor material of the building is only the height of the lower beam of the building unit, and when piping under the floor, the piping space is narrow, so the piping work is difficult There was a problem.

[0005] In order to solve such a problem and secure piping space for a unit-type building, it is conceivable to provide a cloth foundation-like rising portion on the upper surface of the RC frame. After constructing the RC frame by casting, it is necessary to cast concrete again to form a rising portion, which causes a problem that the concrete placing operation becomes complicated.

SUMMARY OF THE INVENTION An object of the present invention is to facilitate piping under a floor without providing a cloth foundation-like rising portion on the upper surface of a cast-in-place concrete pedestal and without impairing the ceiling height in a room.
