摘要： PROBLEM TO BE SOLVED: To provide a reinforcement anchoring structure which can surely cause a fracture in base material of a reinforcement, without making a screw portion become a weak point, by properly managing tensile strength of a joint between the screw portion and a nut. SOLUTION: This reinforcement anchoring structure comprises a tapered screw portion 30 which is formed by cutting an end of the reinforcement 10 in a tapered shape after plastically hardening it, and a nut 40 which is screwed to the tapered screw portion 30. The pulling strength of the joint between the tapered screw portion 30 and the nut 40 is set to exceed that of the base material of the reinforcement. COPYRIGHT: (C)2010,JPO&INPIT
