A standard building unit 110A with no beams may be arranged. Also, as shown in FIG. 2B, the standard building unit 10 is arranged on the lower-floor standard building unit 110 and the standard building unit 10 is arranged on the lower-floor special building unit 120. May be.

(Fourth Embodiment) (FIG. 14) The fourth embodiment is different from the third embodiment in that a special building unit 1 without beams is used instead of the special building unit 120 with no beams.
20A has been used. Beam special building unit 120
A shows the gate-shaped frame 131 of the small unit 130 and the beam omitted unit 140 in the beam special building unit 120.
In this embodiment, one of the portal frames 143 is deleted, and the portal frame 131 and the portal frame 143 are provided with a single portal frame 121 from the beginning without overlapping. Other structures of the beam omitted special building unit 120A are the same as those of the beam omitted special building unit 120, have the same standard dimensions as the beam omitted standard building unit 110, and form a unit building 1B together with the beam omitted standard building unit 110. This is the same as in the third embodiment.
