STRUCTURE FOR REINFORCING STEEL PIPE
PROBLEM TO BE SOLVED: To provide a structure for reinforcing a steel pipe, which can increase the buckling strength and axial strength of the steel pipe and which can facilitate execution of work, and a method for reinforcing the steel pipe.SOLUTION: A structure 1 for reinforcing a steel pipe, which is provided in an existing structure 11 to reinforce a steel pipe 2 constituting a structure, includes a reinforcing filler (filler) 4 that is infilled into a reinforcement object range 16 within the steel pipe 2, and a high-tension bolt (tendon) 5 that passes through the steel pipe 2 and the reinforcing filler 4 and into which a predetermined tensile force is introduced to push the steel pipe 2 against the reinforcing filler 4.SELECTED DRAWING: Figure 2
【課題】鋼管の座屈耐力および軸耐力を増大させることができるとともに、容易に施工することができる鋼管の補強構造、および鋼管の補強方法を提供する。【解決手段】既存構造物１１に設けられて、構造体をなす鋼管２を補強する鋼管の補強構造１において、鋼管２の内部における補強対象範囲１６内に充填された補強用充填材（充填材）４と、鋼管２および補強用充填材４を貫通し、所定の張力が導入されて鋼管２を補強用充填材４へ押圧するハイテンションボルト（緊張材）５と、を有する。【選択図】図２
