ている（特開昭56−111726号公報）。(Prior Art) The pile head reinforcing bar is for reinforcing the head of a pile that is driven into the ground and increasing the bonding force between it and the foundation of the structure. It consists of a reinforcing bar cage that is fitted into the section and held by a stopper, and a saucer that is fitted into the lower part of the reinforcing bar cage and fitted into the pile head. The conventional example has a structure in which a screw rod is protruded from the lower part of the reinforcing bar cage via a radial support rod, and the notched saucer and the center of the bottom plate are fitted into the screw rod and attached with nuts (Japanese Patent Application Laid-open No. 56-111726).
