REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD FOR EXISTING REINFORCED CONCRETE WALL

PROBLEM TO BE SOLVED: To provide a reinforcement structure and a reinforcement method for an existing reinforced concrete wall that provide shear reinforcement and allow suppression of buckling of a main reinforcement caused by repeated application of load.SOLUTION: A reinforcement structure for an existing reinforced concrete wall includes: a first reinforcement member insertion hole 20 bored from one surface side toward the other surface side and having a bottom; a first reinforcement member 30 inserted into the first reinforcement member insertion hole 20; a second reinforcement member insertion hole 40 bored from the other surface side toward the one surface side and having a bottom; and a second reinforcement member 50 inserted into the second reinforcement member insertion hole 40. The first reinforcement member insertion hole 20 has a bottom surface located closer to the one surface side than to a main reinforcement 11 and a distribution reinforcement 12 on the other surface side. The first reinforcement member 30 has a first wire rod 31 and a first engaging portion 32 that engages with the main reinforcement 11 on the one surface side. The second reinforcement member insertion hole 40 has a bottom surface located closer to the other surface side than to the main reinforcement 11 and the distribution reinforcement 12 on the one surface side. The second reinforcement member 50 has a second wire rod 51 and a second engaging portion 52 that engages with the main reinforcement 11 on the other surface side.
