REINFORCEMENT METHOD OF EXISTING COLUMN AND REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforcement method of an existing column and a reinforcement structure which can restrain a core concrete of the existing column from a corner side which is a boundary portion between a surface on which an obstacle exists and a surface adjacent to the surface in the existing column to be reinforced, and can improve the deformation performance.SOLUTION: Provided is a reinforcement structure of an existing column in which a core concrete of a cross-sectional square existing column 1 is restrained from a corner 1f side which is a boundary portion between first surfaces (1a, 1d) where an obstacle 100 exists and second surfaces (1b, 1c) adjacent to the first surfaces in the existing column 1. The reinforcement structure has a reinforcing member 42 for restraining the core concrete of the existing column 1 from the corner 1f side of the existing column 1 by being embedded from the second surface side of the corner 1f side to a position closer to the center of the existing column 1 than a position of a hoop 12 arranged in the existing column 1.SELECTED DRAWING: Figure 8
【課題】補強対象の既設柱において支障物が存在する面と当該面と隣り合う面との境界部分である角部側から当該既設柱のコアコンクリートを拘束できて、変形性能を向上させることが可能な既設柱の補強方法及び補強構造を提供する。【解決手段】断面四角形の既設柱１において支障物１００が存在する第１の面（１ａ，１ｄ）と当該第１の面と隣り合う第２の面（１ｂ，１ｃ）との境界部分である角部１ｆ側から当該既設柱１のコアコンクリートを拘束する既設柱の補強構造であって、角部１ｆ側の第２の面側から既設柱１内に配筋された帯筋１２の位置よりも既設柱１の中心に近い位置まで埋め込まれて既設柱１のコアコンクリートを既設柱１の角部１ｆ側から拘束する補強部材４２を備えたことを特徴とする。【選択図】図８
