In general, in order to mold the slab during construction of a building structure, formwork is installed in a horizontal direction orthogonal to the wall surface in a state where a wall of the building is formed, and the formwork is arranged to support the formwork by arranging a plurality of clubs on the formwork. After the concrete is put into the formwork so that the slab is cured, the installed formwork is removed to complete the slab.

In the case of a multi-layered structure, likewise, the wall formwork is constructed, and then the formwork is installed in the horizontal direction on the wall formwork, and then the concrete is poured and the same construction is repeated to construct the multi-layered building structure.
