As shown in FIG. 8A, the steel beam 1 transported to the site by the truck 14 is horizontally supported by the support base 15 at the site as shown in FIG. Then, the pillar formwork 3 is erected for each pillar that has been assembled. Thereafter, as shown in FIG. 8C, the building work is performed as a through steel beam / assembly reinforced pillar / column formwork module. However, the rebar columns 2 can be attached at the factory and only the column form 3 can be built at the site.

Finally, FIG. 9 shows an embodiment in which the building is carried out with a module for one span. Except that the length of the steel beam 1 is equivalent to one span, the contents are technically common to the above inventions. In addition, the length of the assembled reinforcing steel column 2 is formed to be the same as the length of the assembled reinforcing steel column 2 in accordance with the width of the truck bed on the premise that the assembled reinforcing steel column 2 is attached to the steel beam 1 at the factory and transported by truck. This is shown.
