PURPOSE: A groove is formed on one side of a support circular plate, and a nut protruding from the end of a concrete column is inserted into the groove so that the support circular plate is closely attached to a prestressed high-strength concrete (PHC) pile. CONSTITUTION: A support circular plate (50) is fixed to the end of a concrete column (10) by a bolt (40). A ring-shaped groove (53) is formed on one side (52) of the support circular plate. A protruding nut (30a) among the nuts (30) inserted into the end of the concrete column is inserted into the groove of the support circular plate and is closely attached. A first reinforcing rib (55) and a second reinforcing rib (66) are formed on the other side (54) of the support circular plate in a ring shape. A plurality of third reinforcing ribs is radially formed in the second reinforcing rib. A bolt hole (58) is formed on between the first reinforcing rib and the third reinforcing rib. |
