PROBLEM TO BE SOLVED: To provide an additionally placed reinforcement structure of an existing column, capable of improving transmission of shear stress between the existing column and an additionally placed part while drastically decreasing the number of post-construction anchors for anchorage to be used, and suitable for performing a simple earthquake strengthening method for an existing building.SOLUTION: In a reinforcement structure of an existing column in which reinforced-concrete is additionally placed on an outer surface of the existing column, a plurality of post-construction anchors 7 for anchorage are installed over concrete 5 of the existing column 1 and an additionally placed concrete 6, and flat plates 8 each having a plate surface orthogonal to the outside surface of the existing column are installed in a vertical direction over a concrete part 5a on the outer surface side than a tie hoop among the concrete of the existing column and the additionally placed concrete. |
