Since the connecting plate protruding from the end of the PC beam is connected to the connecting plate of the PC beam, and the connecting bars are arranged above the PC beam and the beam, the amount of steel can be reduced and construction costs can be reduced. It is also possible to ensure the continuity of joints and prevent deterioration in seismic performance. Since the main beam reinforcement of the PC beam and the main beam reinforcement of the PC beam are connected via the joint plate, stress transmission at the joint can be carried out smoothly, and the beams can be integrated. Since the main beam reinforcement also serves as a means for attaching the joint plate, there is no need for a means for attaching the joint plate, so the amount of steel material can be reduced and the structure of the joint can be simplified.
