REINFORCEMENT UNIT FOR HOLLOW COLUMNAR OBJECT AND REINFORCEMENT METHOD FOR HOLLOW COLUMNAR OBJECT

To provide a reinforcement unit for a hollow columnar object in a new structure and a reinforcement method for the hollow columnar object with the reinforcement unit.SOLUTION: A reinforcement unit 1 for reinforcing a hollow columnar object from the inside of the hollow columnar object, comprises: a reinforcement member 20 in a cylindrical shape arranged inside of the hollow columnar object; a plurality of bag members 40 arranged in an inside space of the reinforcement member; a partition member 30 separating the inside space of the reinforcement member into a plurality of individual spaces where each of the plurality of bag members is arranged. The partition member extends in an axial direction of the reinforcement member. The reinforcement member is allowed to be deformed so as to closely contact an inner wall of the hollow columnar object by expansion of each of the plurality of bag members. Each of the plurality of expanded bag members extends in the axial direction of the reinforcement member.SELECTED DRAWING: Figure 13 【課題】新規な構造の中空柱状物の補強ユニットと、この補強ユニットによる中空柱状物の補強方法とを提供することを目的とする。【解決手段】中空柱状物の内側から中空柱状物を補強する補強ユニットであって、本ユニット１は、中空柱状物の内側に配置される筒状の補強部材２０と、補強部材の内部空間に配置される複数の袋部材４０と、補強部材の内部空間を、複数の袋部材それぞれが配置される複数の個別空間に分割する仕切部材３０と、を有してなり、仕切部材は、補強部材の軸方向に延在し、補強部材は、複数の袋部材それぞれが膨張することで、中空柱状物の内壁に密着するように変形可能で、膨張した複数の袋部材それぞれは、補強部材の軸方向に延在する。【選択図】図１３
