In addition, since the bottom slab protrudes laterally from the straight wall, there are problems in that not only is the stocking and transportation efficiency very poor, but also the workability is poor. Furthermore, in order to sufficiently withstand the bending moment that acts on the side walls and bottom plate, the thickness of the side walls and bottom plate and the amount of reinforcing bars must be increased, which not only makes it difficult to reduce manufacturing costs but also increases the amount of reinforcement required. There was a problem with the weight. Furthermore, it is difficult to miniaturize and simplify the manufacturing equipment (formwork, demolding machine, rotary machine, etc.) with a monolithic structure.
