PROBLEM TO BE SOLVED: To provide a technology for manufacturing a column-shaped structure such as a bridge pier having high durability and high strength by means of an easy technique. SOLUTION: A vertical main reinforcement 2 for a column 4 is arranged, a plurality of vertically split precast concrete panels 10 are stood on the outside of the reinforcement 2 into a cylinder, and a PC steel material 11 connecting the precast panels 10 together is inserted spirally in the thickness part of the precast panel cylinder. Using the precast panels 10 as a form, concrete is placed in the inside of them. After the placed concrete is cured, the PC steel material 11 is fastened so that the placed concrete is fastened to be integrated by the precast panels 10. |
