Document Type and Number:
Japanese Patent JP7330071
Kind Code:
B2
Abstract:
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
