とする。Further, the jointing formwork becomes a reinforced concrete structure having high rigidity due to the longitudinal reinforcements, stiffening reinforcements and hoop reinforcements provided therein. Therefore, the casting formwork supports the lateral pressure from the concrete cast in situ without being supported by the surroundings. In addition, the lateral wall reinforcement member projecting in the wall thickness direction of the joint form made of a PCa member thinner than the concrete wall thickness to be cast in-situ supports the lateral wall reinforcement by locking the lateral wall reinforcement in the notch. It eliminates the need for joint work with
