PROBLEM TO BE SOLVED: To provide a repeatedly usable concrete formwork retainer having a member which is integrally formed therewith for facilitating engagement work of a concrete formwork panel with a shaft leg and stably fixing the concrete formwork panel, and which allows the concrete formwork panel to be easily peeled off from a cured concrete wall to facilitate disassembling work.SOLUTION: The concrete formwork retainer includes: a shaft leg body 11 which is coupled with a separator 16 and is detachably attached to a concrete formwork panel 15; a female screw cylinder part 12 of the shaft leg body 11; a male screw part 13 which is screwed with a concrete formwork fastener 22 of the shaft leg body 11; and a locking disk part 14 having a flange shape, which is integrally formed with the shaft leg body 11 in an intermediate part thereof. The concrete formwork retainer is arranged to be separated from the concrete formwork panel 15 which is in close contact with concrete C by means of the locking disk part 14 after the concrete C is cured.SELECTED DRAWING: Figure 1 |
