PROBLEM TO BE SOLVED: To provide a shear reinforcement method by which a filler can be efficiently utilized as a reinforcement material by letting the filler sufficiently wrap around a shear reinforcement material, sufficient fixing strength can be obtained, and a construction can be easily carried out.SOLUTION: A shear reinforcement material 13 is integrally provided with a diameter-expansion fixing part 16 at a tip part, and has a sharp part 17 shaped to have a sharp tip at the tip side further than the diameter-expansion fixing part 16. In a drilling step, a reinforcement material insertion hole 12 is formed, with a constant inner diameter larger than an outer diameter of the diameter-expansion fixing part 16 of the shear reinforcement material 13, from a base end opening 12a up to the depth at which a tip hole bottom part 12b is arranged close to a main reinforcement 20a on another side wall surface 11b side. In a reinforcement material installation process, the shear reinforcement material 13 is installed while being separated from an inner peripheral surface of the reinforcement material insertion hole 12 by bringing the tip of the sharp part 17 into contact with the tip hole bottom part 12b of the reinforcement material insertion hole 12 and by inserting a base end side part into an annular spacer 18 arranged inside the reinforcement material insertion hole 12. |
