Title:
鉄筋コンクリート構造物の補強方法
Document Type and Number:
Japanese Patent JP6861190
Kind Code:
B2
Abstract:
To provide a reinforcing method of a concrete structure capable of preventing damage of concrete due to rust of reinforcing bars in a reinforced concrete structure by suppressing corrosion of the reinforcing bars and improving adhesion performance of a fiber sheet to the surface of the reinforced concrete structure.SOLUTION: A reinforcing method of a reinforced concrete structure 100 for bonding and integrating a fiber sheet 1 containing reinforcing fibers, includes the steps of (a) coating the surface of the reinforced concrete structure with a silane impregnating material 102, (b) forming a primer layer 104 by applying a primer 103 containing a silane coupling agent to the surface of a reinforced concrete structure coated with a silane-based impregnation material 102, and (c) bonding the fiber sheet 1 to the surface of the reinforced concrete structure having the primer layer 104 formed thereon with an adhesive 105.SELECTED DRAWING: Figure 1
