きくできる。As described above, according to the structure of the stepped floor of the present invention, the truss reinforcing bars of the upper and lower floor members and the reinforcing bars of the small beams are used in common. It is possible to prevent the rebar from interfering with each other, thereby improving the workability at the time of construction, thereby enabling cost reduction. Further, since the upper and lower floor members are separate bodies, the step size can be increased.
