2. Description of the Related Art In a conventional flat plate, a floor formwork is arranged between columns, a floor reinforcing bar is arranged in the formwork, and then on-site concrete is poured, and after the concrete is hardened, it is demolded. Although it was constructed, it requires a floor form material as a temporary construction, and temporary construction work such as temporarily supporting the floor form material and the work space will be narrowed due to the formwork, which requires construction period and cost. There was a problem.

In the past, in order to reduce the construction period and cost, for example, a construction method described in Japanese Patent Publication No. 4-2743 has been proposed. This consists of bridging the pillar row panels between the horizontal slabs, which are integrated with the stigmas, and further bridging the floor panels between the pillar row panels, and arranging the floor reinforcing bars on the floor panels. Later, on-site concrete is cast on the panel to build a flat plate.
