Construction method of civil engineering concrete structure, formwork for concrete placement and civil engineering concrete structure

摘要

PROBLEM TO BE SOLVED: To prevent deterioration of a civil engineering concrete structure in which a concrete skeleton is formed by placing concrete in a concrete placing space and solidifying it due to the influence of the natural environment, and to obtain high quality for a long period of time. Provided are a method of constructing a civil engineering concrete structure, a formwork for placing concrete, and a civil engineering concrete structure capable of maintaining the above. SOLUTION: A formwork panel 12 formed by laminating a heat insulating inner wall 121 and a reinforced outer wall 122 is fixed by a support member of a panel fixing means 70, and is enclosed by a plurality of formwork panels 12 so as to provide a predetermined space. By maintaining the state, the concrete casting space 20 is formed by the plurality of formwork panels 12, concrete is cast in the concrete casting space 20, the concrete is cured, and the concrete is solidified. After that, the support member is removed, and the concrete is solidified to form a concrete skeleton 210 covered with the plurality of formwork panels 12 integrated. [Selection diagram] Fig. 1
