CUSHION CONCRETE PIN

摘要

PROBLEM TO BE SOLVED: To provide a cushion concrete pin capable of preventing occurrence of cracks in concrete when driving the pin. SOLUTION: This cushion concrete pin 11 is constituted of a concrete pin 1, a cylindrical member 12 mounted on a tip side of a body part 2 of the pin 1 in an extended state and an elastic member 13 filled at the inside of the cylindrical member 12. A cushion action is generated because both of the cylindrical member 12 and the elastic member 13 receive compression and mitigates destructive force when advancing the concrete pin 1 into concrete A.
