Since the floor rigidity is increased, when the floor structure 21 of the upper floor building unit 13 is mounted on and supported on the wall panel 22 of the lower floor building unit 12, the wall panel 22 is not erected in the lower floor building unit 12. Girder direction span L1, wife direction span L2 (Fig. 2)
The floor structure 2 of the upper-floor building unit 13
Due to the high rigidity of 1, the deflection at the time of walking can be sufficiently suppressed, and the floor vibration can be sufficiently reduced.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and the design can be changed without departing from the scope of the present invention. The present invention is also included in the present invention. For example, in the practice of the present invention, the aforementioned high-rigid floor girders 31, 32,
A structure in which a reinforcing plate is attached to a wooden joist of 33 may be used for a floor beam. Further, the above-mentioned structure in which the reinforcing surface material and the reinforcing wooden beam are attached to the side surface of the I-beam material of the small floor beam 24 may be adopted for the large floor beam.
