REINFORCING STRUCTURE OF HOLLOW CONSTRUCTION AND REINFORCING METHOD

PROBLEM TO BE SOLVED: To provide a reinforcing structure of a hollow construction which can effectively repair and reinforce the hollow construction while enabling the impregnation work of resin by preventing the ooze-out of the resin into the construction when reinforcing the hollow construction having a defective region with the fiber-reinforced resin, and to provide a reinforcing method.SOLUTION: There is provided a reinforcing structure of a hollow construction having a defective region which comprises: a fiber-reinforced resin tape A which is pasted at least on a surface of the hollow construction surrounding the defect region; and a solidified fiber-reinforced resin sheet B in which a thermosetting resin is impregnated into a fiber-reinforced sheet and which is pasted on the surface of the hollow construction so as to completely cover the fiber-reinforced tape A. There is also provided a reinforcing method of the hollow construction. 【課題】欠損部位が生じた中空構造物に対して繊維強化樹脂で補強するに際し、樹脂の構造物内部への浸出しを防いで樹脂の含浸作業を可能にして効果的に補修、補強可能な中空構造物の補強構造体及び補強方法を提供する。【解決手段】表面に欠損部位を有する中空構造物に対し、少なくとも、欠損部位を囲む中空構造物の表面上に貼付され、強化繊維が混入された繊維強化樹脂テープＡと、繊維強化樹脂テープＡを完全に覆うように中空構造物の表面上に貼付された強化繊維シートに熱硬化性樹脂が含浸され硬化されて形成された繊維強化樹脂シートＢと、を具備する中空構造物の補強構造体、及び中空構造物の補強方法。【選択図】図１
