REINFORCING STRUCTURE FOR GIRDER STRUCTURE AND ITS CONSTRUCTION METHOD
To provide a reinforcing structure of a girder structure capable of reducing fatigue of a main girder by suppressing deformation and vibration of the main girder against loads repeatedly received in the vertical direction.SOLUTION: In the reinforcing structure of a girder structure, a laminated reinforcing material 1 having a reinforcing layer 3 impregnated with reinforcing fibers 31 on one surface of a liquid-impermeable edge cutting layer 2 and an adhesive layer 4 on the other surface is provided along the longitudinal direction of a main girder 13 of a girder structure such as a bridge 10, and the laminated reinforcing material 1 is bonded to a lower surface 1331 of the main girder 13 by the adhesive layer 4.SELECTED DRAWING: Figure 4
【課題】上下方向に繰り返し受ける荷重に対する主桁の変形、振動を抑制して主桁の疲労を低減することができる桁構造物の補強構造を提供する。【解決手段】非通液性の縁切層２の一方の面に補強繊維３１が含浸された補強層３を有し、他方の面に接着層４を有する積層補強材１が、橋梁１０などの桁構造物の主桁１３の長手方向に沿うように設けられ、積層補強材１が接着層４で主桁１３の下面１３３１に接着されている桁構造物の補強構造。【選択図】図４
