PROBLEM TO BE SOLVED: To provide a reinforcement for a corner of a wall opening having good adhesion performance to concrete by forming a recess or a projection on the surface of the reinforcement. SOLUTION: The width (b) of a reinforcement is made smaller than the thickness t of a wall, thereby preventing the reinforcement 1 from getting exposed outside from the wall and from interfering with a vertical reinforcement and a horizontal reinforcement of the wall 10. And then holes 14 for inserting fixing hardware 4 into the reinforcement 1 are made in the reinforcement 1. And a formwork 6 for an opening 5 is attached to a wall formwork, and the reinforcement 1 is set on the wall 10 side of a corner 15 and fixed with the fixing hardware 4. In addition, after concrete is placed for the wall 10 and set, the formwork 6 is removed together with the wall formwork, and a sash is incorporated. And then, non-shrinking mortar is filled into the clearance thereby exhibiting the function of adhering to concrete, restraining concrete around the corner, dissipating and relaxing tensile stress of the corner, resultantly preventing a crack from occurring.
