PROBLEM TO BE SOLVED: To provide a sheathing tool for concrete capable of positively damming concrete by lowering leg bodies onto a form while avoiding a reinforcement even if the leg bodies are positioned on the reinforcement. SOLUTION: The damming tool for concrete is formed in comb tooth shape by providing the longitudinal leg bodies for damming concrete, parallel at prescribed spaces along a support body. The leg bodies are disposed movably right and left along the support body, and elastic bodies are interposed in the elastically deformed state between the adjacent leg bodies to provide the leg bodies parallel at suitable spaces. The leg bodies are moved right and left against the resilience of the elastic bodies to adjust the spacing of the leg bodies. COPYRIGHT: (C)2004,JPO&NCIPI
