<P>PROBLEM TO BE SOLVED: To provide a separator which fastens and fixes two separators when the two separators slide simultaneously forward and backward and their positions are determined, while a plastic cone can be easily removed by a conventional plastic cone removal tool after demolition of a concrete form. <P>SOLUTION: A separator is configured by connecting a basic separator 20 and an adjustable separator 30 and fixing them in accordance with the width of a concrete form, a hexagonal shaft 53 which is somewhat smaller than a hole opened in the concrete form in diameter is provided in the shaft of the plastic cone 60, and a male screw 56 is formed from a hexagonal shaft side to a shaft center, on an inclined surface part 54, and a tip, thus stably building the concrete form. Even when a cavity part of the plastic cone is fully filled with cement slime after demolition of the concrete form, the plastic cone can be easily removed by turning the hexagonal shaft by a somewhat smaller box wrench or a spanner because the hexagonal shaft projects from the surface of concrete. <P>COPYRIGHT: (C)2013,JPO&INPIT |
