REINFORCEMENT METHOD OF CONCRETE STRUCTURE, AND REINFORCEMENT STRUCTURE
To provide: a reinforcement method of a concrete structure using a fixing anchor capable of achieving a desired reinforcing effect while avoiding occurrence of peeling at the edges of a reinforcing fiber sheet attached to the concrete structures; and a reinforcement structure.SOLUTION: The reinforcement method is performed to glue a continuous fiber reinforcement member onto a surface of a concrete structure and fix ends of the continuous fiber reinforcement member to the concrete structure with a fixing anchor 1. The fixing anchor 1 is formed by aligning continuous fiber strands, which are formed using a continuous reinforcing fiber bundle consisting of many continuous reinforcing fibers converged in one direction. The fixing anchor has a mounting portion 1a on one side in an axial direction and a fixing part 1b on the other side. The mounting part is shaped in a long thin rod. The fixing part has a wide sheet-shaped fixing part 1b1 and a fan-shaped fixing part 1b2. The reinforcement method includes the steps of: impregnate the fixing anchor with resin; embedding the mounting part on one side of the fixing anchor into a mounting hole formed in the concrete structure; and gluing and fixing the other fixing part of the fixing anchor to the end of the continuous fiber reinforcement member.SELECTED DRAWING: Figure 1
【課題】コンクリート構造物に貼り付けて補強する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定着アンカーを使用した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】連続繊維補強部材をコンクリート構造物の表面に接着し、連続繊維補強部材の端部を定着アンカー１にてコンクリート構造物に定着し、定着アンカー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、軸線方向の一側に取付部１ａを他側に定着部１ｂを有しており、取付部は、細長棒状に賦形されており、定着部は、広幅シート状定着部１ｂ１と扇状定着部１ｂ２とを有しており、定着アンカーに樹脂を含浸させ、定着アンカーの一側の取付部を、コンクリート構造物に形成した取付孔に埋め込み、定着アンカーの他側の定着部を、連続繊維補強部材の端部に接着して定着する。【選択図】図１
