The width of the lower floor reinforcing beam 30 is determined by the height of the ceiling beam 23 of the lower floor building unit 12 and the height of the upper floor building unit 1.
1 (12), which is larger than the sum of the heights of the floor beams, and the reinforcing performance of the lower reinforcing beams is increased. For this reason, the ceiling span where the columns are omitted can be greatly enlarged, and a wide continuous space where the columns are omitted can be formed.

Most of the lower floor reinforcing beams 30 are installed so as to be sandwiched between two adjacent ceiling beams 23 of the building unit 12 adjacent to each other. Therefore, the reinforcing beam 30 does not protrude greatly below the ceiling beam 23, and the ceiling height under the beam can be made as high as possible.

The lower reinforcement beam 30 is formed by connecting the ceiling beam 23 to the pillar 2.
