A head reinforcing apparatus of a PHC pile is provided to increase coupling strength of concrete by an upper support member placed on the upper part of a PHC pile and to reinforce a head of a pile strongly. A head reinforcing apparatus of a PHC pile comprises an upper support member(30) twisted repeatedly to form reinforcing bar fitting portions(32) between connections(35A) and to heighten coupling strength with concrete, a lower support member(50) formed to be inserted to the inside diameter of a PHC pile(10) to support a reinforcing bar(20) and to prevent the inflow of concrete to the inside diameter excessively, and connection members(40) connecting the upper support member and the lower support member to fix the lower support member to the appointed location of the inside diameter. |
