で問題があった。Conventionally, an RC building having a rigid frame structure using a precast member (PC member) is
In general, the size of the beam is large and the floor height is high. In addition, since the panel zone of the PC member frame where the columns and beams intersect is generally constructed with cast-in-place concrete, a complex formwork is required in the panel zone, and it is difficult to fill concrete with mixed reinforcement. There was a problem in ensuring equal quality.

The connection with the beam becomes complicated. In addition, when the PC beam members in the X and Y directions that intersect in the panel zone have a rigid frame structure in both directions, the beam main bars in both the X and Y directions cross in the panel zone, so There is a drawback that joining is complicated and time-consuming.
