REINFORCING METHOD AND REINFORCING STRUCTURE FOR REINFORCED CONCRETE STRUCTURE

To provide a reinforcing method of a reinforced concrete structure and a reinforcing structure constructed by the reinforcing method for reinforcing an existing reinforced concrete structure upward, which are excellent in a shear reinforcing effect, free from the possibility of corrosion of reinforcing reinforcement, and capable of achieving reinforcing construction in a short time as much as possible.SOLUTION: A reinforcing method of a reinforced concrete structure reinforcing an existing reinforced concrete structure 30 by constructing a reinforcing reinforcement 50 upward from a lower surface 31 of the reinforced concrete structure 30, comprises: a drilling step for drilling a hole 35 upward from a lower surface 31 of the reinforced concrete structure 30; a filling step for filling the hole 35 with a filler 60; and an insertion supporting step of inserting the reinforcing reinforcement 50 into the hole 35, positioning its lower end at a midway position of the hole 35, inserting a plate-like elastic body 10 into the hole 35 to be locked to the wall surface of the hole 35, and supporting the reinforcing reinforcement 50 by the plate-like elastic body 10.SELECTED DRAWING: Figure 6 【課題】既設の鉄筋コンクリート構造物を上向きに補強する補強方法と補強構造に関し、せん断補強効果に優れ、補強鉄筋の腐食の恐れがなく、可及的に短時間に補強施工を実現することのできる、鉄筋コンクリート構造物の補強方法と、この補強方法により施工される補強構造を提供する。【解決手段】既設の鉄筋コンクリート構造物３０の下面３１から補強鉄筋５０を上向きに施工して鉄筋コンクリート構造物３０を補強する、鉄筋コンクリート構造物の補強方法であり、鉄筋コンクリート構造物３０の下面３１から、上向きに孔３５を削孔する削孔工程と、孔３５に充填材６０を充填する充填工程と、補強鉄筋５０を孔３５に挿入してその下端を孔３５の途中位置に位置決めし、板状弾性体１０を孔３５に挿入して孔３５の壁面に係止させ、補強鉄筋５０を板状弾性体１０により支持する挿入支持工程と、を有する。【選択図】図６
