PROBLEM TO BE SOLVED: To solve the problem of thickening of an additional reinforced wall and requiring arrangement work of a splitting preventing reinforcement in a conventional supplementary reinforced wall method of an existing concrete wall. SOLUTION: A plurality of anchors 1, 1a are driven to columns Y, Ya and beams X, Xa. Respective reinforcing frames 2, 2a, 3, 3a arranged in parallel with the columns Y, Ya and the beams X, Xa with the plurality of the driven anchors 1, 1a are fixed by the plurality of the anchors 1, 1a. Ends of a plurality of vertical and horizontal reinforcing bars 4, 4a, 5, 5a arranged in the reinforcing frames 2, 2a, 3, 3a are fixed to the reinforcing frames 2, 2a, 3, 3a. An outer peripheral part of the supplementary reinforced wall 8 formed of the reinforcing frames 2, 2a, 3, 3a and the vertical and horizontal reinforcing bars 4, 4a, 5, 5a buried by mortar 7 are reinforced by the reinforcing frames 2, 2a, 3, 3a. Accordingly, splitting of the supplementary reinforced wall 8 to the outer periphery is prevented without arranging the splitting preventing reinforcement even when the supplementary reinforced wall 8 is thinned.
