PURPOSE:To simplify the treatment of the pile head by a method in which reinforcing bars provided with projected members are covered with a covering material, concrete is placed and hardened, and then a static breaker is packed into holes provided in places to be cut off of the concrete. CONSTITUTION:Wedge-shaped projected members 2 are provided to reinforcing bars 1 positioned in an extra-banking concrete, the reinforcing bars 1 are covered with a covering material 5, and concrete is placed. After the concrete hardens, a static breaker is packed into plural holes provided in places 6 to be cut off of the concrete. The places 6 to be cut off of the extra-banking concrete 8 are broken by the expansion pressure of the breaker. |
