PURPOSE:To reuse concrete piles by fixing a coupler consisting of the main body of an L-shaped cross section and a flange to support the main body to the body of reinforced concrete in a detachable manner. CONSTITUTION:The flange 9 of a coupler 7 is attached to the buried nuts 10 of a reinforced concrete body 2 by screwing bolts 12 with the nuts 10 to make up a concrete pile 1. Since the coupler 7 can be detachably fixed to the body 2, the concrete body 2 can be reused by exchanging any one of the body 2 and the coupler 7 with new one even when they are damaged. |
