<p>PROBLEM TO BE SOLVED: To provide a method and a device for introducing prestress in a circumferential direction of a reinforced concrete body.SOLUTION: A reaction receiving member is arranged in such a manner as to be extended in the same direction as that of a main reinforcement 11, in a position to abut on an inside part of a reinforced concrete body 1. An inner end of a pushing member 20 abuts on the reaction receiving member, and an outer end of the pushing member 20 abuts on a shear reinforcement 12. Furthermore, the pushing member 20 is extended to push the shear reinforcement 12 outward and put the shear reinforcement 12 in a tensioned state. In the tensioned state, concrete 10 is placed. After the concrete is hardened, the reaction receiving member is extracted and removed.</p> |
