CONSTRUCTION METHOD FOR CONCRETE STRUCTURE, FORM BLOCK USED IN THE METHOD, AND FORM BLOCK MANUFACTURING METHOD

Japanese Patent JP3947459

B2

PROBLEM TO BE SOLVED: To provide a construction method for a concrete structure for performing construction quickly and power-savingly, a form block used in the method and a manufacturing method for the form block.
SOLUTION: A concrete-made cylindrical form block 1 is formed by axially attaching a pair of elastic fins 13, 13 formed of an elastic material into a long plate diagonally to the outer peripheral surface of the body. A plurality of these form blocks constitute a partition part with the elastic fins 13, 13 of the adjacent form blocks 1, 1 overlapping each other, and simultaneously block rows A are formed side by side horizontally to demarcate a construction boundary T. The whole of the thus formed block rows A is taken as a form, and concrete C is placed within the demarcated construction boundary T to form the body concrete layer B. The above steps are sequentially repeated to construct a concrete structure.
