Abstract:
PROBLEM TO BE SOLVED: To provide a concrete structure construction method and a concrete installation formwork, which enable the formwork to be easily assembled and disassembled.SOLUTION: A concrete panel 12 formed by fitting and connecting outer edges 11 of an uneven unit panel 10 with each other is disposed and maintained so as to surround a cavity 20. A concrete installation formwork comprises: a support member 30 and a building frame side formwork fixing material 50, which have the same shape and support the concrete panel 12 by contacting an outside surface 12a of the concrete panel 12, and can be used repeatedly; a formwork fixing rod 40, which penetrates fitting holes 13, 33 drilled on the unit panel 10 and the support member 30, respectively; and a locking means 60, which is disposed on at least one end 41 of the formwork fixing rod 40. The support member 30 is disposed across a connection part 11a. The cavity 20 is formed by disposing the building frame side formwork fixing material 50, the concrete panel 12 and the support member 30 in this order on a section from a central part O in a lengthwise direction of the formwork fixing rod 40 to one end 41.SELECTED DRAWING: Figure 1
