ASEISMATIC REINFORCEMENT STRUCTURE OF CONCRETE COLUMN
PROBLEM TO BE SOLVED: To provide an aseismatic reinforcement structure of a concrete column of a simple structure that may be assembled readily, and prevents damage caused by deformation of a fiber sheet installed on an outer periphery.SOLUTION: An aseismatic reinforcement structure of a concrete column includes: a body part having a U-shaped or a semi-circular cross-section and a corner part with a curved surface, with top and bottom horizontal reinforcement ribs extending horizontally inward at top and bottom of the body part, and connection ribs extending forward from both edges of the body part; a reinforcement member installed continuously in a vertical direction on a surface side of the concrete column; a pair of L-shaped fixing members having a reinforcement length of the concrete column and being fixed with an anchor bolt on the surface side of the concrete column; a tie rod fixed while being linked with the connection ribs on both edges of the reinforcement member and the fixing members fixed on the concrete column; a fiber sheet installed on an outer periphery of the reinforcement member; and a solidification agent filled in a gap between the surface side of the concrete column and the reinforcement member.SELECTED DRAWING: Figure 4
【課題】構造が簡単で組み立て作業が容易で、外周に配置する繊維シートの変形による損傷を無くすことが可能なコンクリート柱の耐震補強構造を提供することを目的とする。【解決手段】コーナー部を曲面とした断面コ字形又は断面半円形の本体部の上下に内側に水平に伸びる上下水平補強リブと、本体部の両端から前方に伸びる連結リブを形成し、コンクリート柱の一面側に上下方向に連設される補強部材と、コンクリート柱の一面側にコンクリート柱の補強長さを有しアンカーボルトで固定される一対のＬ字形の固定部材と、補強部材の両端の連結リブとコンクリート柱に固定された固定部材に連通して固定するタイロッドと、補強部材の外周に配置される繊維シートと、コンクリート柱の一面側と補強部材との間の空隙に充填される固化剤と、からなることを特徴とする。【選択図】 図４
