Since the projections are provided on the outer surface of the steel plate form 110, the rigidity of the steel plate form 110 itself can be increased as compared with the case where no such projections are provided. Therefore, less support work is required compared with the conventional formwork method. Therefore, the labor required for supporting work can be reduced. As a result, the cost required for building a building and the construction period can be reduced.

In addition, the convex portions 110 are formed on both side surfaces and the lower surface of the steel plate form 110.
Since the a and 110b are provided, the steel plate form 110 itself can also resist the bending moment. Further, since the adhesion area with the cast-in-place concrete becomes large, the adhesion force with the cast-in-place concrete can be increased. Furthermore, in the case of performing fireproof coating or other footwear, the adhesive force with the footwear material can be increased.

Therefore, less support work is required compared with the conventional formwork method. Therefore, the labor required for supporting work can be reduced. As a result, the cost required for building a building and the construction period can be reduced.

また、PC工法においてはPC化した梁を運搬、揚重する
が、本発明における梁はコンクリートを打設したもので

Further, in the PC method, a PC beam is transported and lifted, but since the beam in the present invention is not one in which concrete is cast, the weight of such a beam is smaller than that of the PC method. Therefore, it is possible to reduce the labor required for the transportation and lifting of the beam.

その結果、建築物構築に要する経費を軽減することが
できる。
As a result, the cost required for building a building can be reduced.
