REINFORCEMENT METHOD OF CONCRETE STRUCTURE, AND REINFORCEMENT STRUCTURE
To provide: a reinforcement method of a concrete structure capable of achieving the desired reinforcing effect by using a reinforcement fiber sheet while avoiding occurrence of edge peeling of the reinforcement fiber sheet from the concrete structure; and a reinforcement structure.SOLUTION: A reinforcement fiber sheet 1 includes: a reinforcement fiber sheet body 1c that is constituted of continuous fiber strands arranged, which are formed of a continuous reinforcing fiber bundle consisting of many continuous reinforcing fibers converged in one direction; a pair of mounting parts 1a that is shaped into a long rod on one side and the other side of the reinforcement fiber sheet body in the axial direction; and a pair of fan-shaped fixing parts 1b that expands in a fan-shape from the long rod-shaped mounting part to the reinforcement fiber sheet body between the long rod-shaped mounting part and the reinforcement fiber sheet body, and that connects the long rod-shaped mounting part and the reinforcement fiber sheet body. The reinforcement fiber sheet body and the fan-shaped fixing part of the reinforcement fiber sheet are attached to a surface of a concrete structure with adhesive, the mounting part is embedded in a mounting hole formed in the concrete structure, and fixed with the adhesive.SELECTED DRAWING: Figure 1
【課題】補強繊維シートを使用して、コンクリート構造物からの補強繊維シートの端部剥離の発生を回避し、所期の補強効果を達成することのできるコンクリート構造物の補強方法及び補強構造を提供する。【解決手段】補強繊維シート１は、多数本の連続した強化繊維を一方向に収束した連続強化繊維束にて形成される連続繊維ストランドを配列して形成された補強繊維シート本体１ｃと、補強繊維シート本体の軸線方向の一側と他側にて細長棒状に賦形された取付部１ａと、細長棒状取付部と補強繊維シート本体との間で細長棒状取付部から補強繊維シート本体へと扇状に拡開して細長棒状取付部と補強繊維シート本体とを接続している扇状定着部１ｂと、を有しており、補強繊維シートの補強繊維シート本体及び扇状定着部をコンクリート構造物の表面に接着剤にて接着し、取付部をコンクリート構造物に形成した取付孔に埋め込み、接着剤にて固着する。【選択図】図１
