コンクリート床版を打設するものである。By the way, one of the building construction methods is a method using formwork that also serves as scaffolding (Japanese Patent Publication No. 52-13645). This method involves hanging wire ropes from the top of the steel structure after the steel frame has been erected. The formwork that also serves as a scaffold is suspended from the wire rope via a lifting machine, and the formwork is moved sequentially from the bottom floor to the upper floors, and the final tightening of the steel frame is performed for each floor. After completion, the top floor of the formwork, which also serves as a scaffolding, is used to cast the floor slab for the top floor, and then the concrete slabs for each floor are placed in the same way by lowering the formwork one after another.
しかし、この足場兼用型枠による場合でも、結局は上記
外部足場を要し、また、コンクリートの打設を最上階か
