Construction Method for Preventing Piercing Crack of Reinforced Concrete Structure on the Top of the Pile and the Construction Structure thereof

摘要

PURPOSE: A construction method and construction structure for a reinforced concrete structure are provided to improve the internal force, the durability, and the economic efficiency of the reinforced concrete structure by preventing a penetrating crack of the reinforced concrete structure on a pile base and a construction structure thereof at a low cost. CONSTITUTION: In the reinforced concrete structure obtained by constructing a plain concrete(14) on the top surface of a pile base(12), and constructing a reinforced concrete(10) so that the upper end of the pile base is inserted into the upper part of the plain concrete, after plural pile bases are inserted into a support layer(22), the plain concrete is divided into equal parts by a polyethylene foam plate(16) having a thickness and a width same with the plain concrete, and the outer periphery of the pile upper end is wound with the polyethylene foam plate. After that, the plain concrete is constructed onto the divided ground surface, a polyethylene film(18) is installed on the surface of the plain concrete, and the reinforced concrete is constructed on the top thereof.
