Zusammenfassung:To provide a tubular reinforcing material capable of efficiently reinforcing an existing concrete column.SOLUTION: A tubular reinforcing material 1 is inserted into an existing concrete column and fixed by a filler. The tubular reinforcing material 1 comprises a plurality of tubular reinforcing bodies 4a, 4b which can be connected to each other. Each of the reinforcing bodies 4a, 4b has a reinforcing main body 11 having a maximum outer diameter smaller than the inner diameter of the existing concrete column and having an inner diameter at one end in the axial direction larger than the outer diameter at the other end in the axial direction. Each of the reinforcing bodies 4a, 4b can be connected in a state that the other axial end of the reinforcing main body 11 in the other reinforcing body 4b is inserted into a fitting tube 12 provided at one axial end of the reinforcing main body 11 in the one reinforcing body 4a. In addition, each reinforcing body 4a in the connected state is fixed in the existing concrete column by the filler material.SELECTED DRAWING: Figure 1 【課題】既設コンクリート柱を効率的に補強できる管状補強材を提供する。【解決手段】管状補強材1は、既設コンクリート柱内に挿入されて、充填材によって固定されるものである。この管状補強材1は、互いに連結可能な複数の管状の補強体4a,4bを備える。各補強体4a,4bは、最大外径が既設コンクリート柱の内径より小さく、軸方向の一端部の内径が軸方向の他端部の外径より大きい補強体本体11を有する。そして、各補強体4a,4bは、一の補強体4aにおける補強体本体11の軸方向の一端部に設けられた嵌合管12内に、他の補強体4bにおける補強体本体11の軸方向の他端部が挿入された状態で連結可能である。また、連結された状態の各補強体4aは、充填材によって既設コンクリート柱内で固定される。【選択図】図1
