REINFORCEMENT STRUCTURE OF CONCRETE COLUMN
PROBLEM TO BE SOLVED: To provide a reinforcement structure in which the bearing force of a reinforcement part installed in a specific reinforcement face of an existing column can contribute effectively to improvement in the bearing force of the whole of a reinforcement column.SOLUTION: On a condition of a reinforcement structure in which a reinforcement face 1a of an existing column 1 is surrounded by a reinforcement steel plate 12 and the space between the reinforcement steel plate 12 and the reinforcement face is filled with a grout material 7 so as to form a reinforcement part X, the existing column 1 has a pair of horizontal reinforcement insertion holes 13 and 14 formed which extend continuously to the position passing the position of axial reinforcement arranged along a non-reinforcement face 1b from a reinforcement face 1a and which pass near the inside of a pair of axial reinforcements 2a and 2b nearest to both outer sides among existing axial reinforcements 2 arranged on the side of the non-reinforcement face 1b. Horizontal reinforcements 15 and 16 are inserted in the horizontal reinforcement insertion holes 13 and 14 and are fixed by an adhesive agent, and projections 15a and 16a of the horizontal reinforcements 15 and 16 are buried in the grout material of the reinforcement part X with axial reinforcements 5a and 5b in the reinforcement part.SELECTED DRAWING: Figure 2
【課題】 既存柱の特定の補強面に設けた補強部の耐力が、補強柱全体の耐力の向上に有効に寄与する補強構造を提供すること。【解決手段】 既存柱１の補強面１ａを補強鋼板１２で囲み、補強鋼板１２と補強面との空間内にグラウト材７を充填して補強部Ｘを形成した補強構造を前提とし、既存柱１には、補強面１ａから、非補強面１ｂに沿って設けられた軸方向筋位置を通過する位置に至るまで連続し、非補強面１ｂ側に配置された既存の軸方向筋２のうち、両外側に最も近い一対の軸方向筋２ａ，２ｂの内側近傍を通過する一対の横方向筋用挿入孔１３，１４を形成し、横方向筋用挿入孔１３，１４に挿入し、接着剤で固定した横方向筋１５，１６の突出部１５ａ，１６ａが、補強部Ｘ内軸方向筋５ａ，５ｂとともに補強部のグラウト材中に埋設される構成にした。【選択図】図２
