PROBLEM TO BE SOLVED: To provide a reinforcement structure capable of reliably reducing an outside diameter dimension of a coupler by a simple configuration.SOLUTION: A reinforcement structure includes a deformed bar 1 which has a male screw part 11 provided in a rod-like reinforcement body 10, and a coupler 2 which is screwed to the male screw part 11. The male screw part 11 is formed in a shape in which its diameter D1 is smaller than a diameter D0 of the reinforcement body 10. An end side including the male screw part 11 is formed by being subjected to heat treatment. Thus, since the types of shear reinforcements are not increased, the reinforcements can be easily managed. |
