However, the prior art 1
Has the following problems. (A) The reinforcement frame cannot be installed until the temporary pillar is removed. For this reason, the strength of the building unit is extremely reduced during the period from the removal of the temporary column to the completion of the installation of the reinforcing frame, and the ceiling beam may fall from the column omitted corner portion where the temporary column has been removed. . That is, the workability is poor.

(B) A reinforcing frame extends under the ceiling beam. Therefore, the reinforcing frame projects below the ceiling beam, and the ceiling height under the beam is reduced.

[0008] Further, Conventional Example 2 has the following problems. (A) Omit pillars at the butted part of four building units,
The ceiling beams that intersect each other at the joints where the pillars are omitted are merely connected integrally by the reinforcing connection tool. For this reason, the ceiling structural strength of this unit building cannot be more than the sum of the cross-sectional performances of two ceiling beams adjacent to each other in the adjacent building unit. Therefore, there is a limit to the expansion of the ceiling span where the columns are omitted, and there is a limit to the expansion of a wide continuous space where the columns are omitted.
