Document Type and Number:
Japanese Patent JP2017223093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To concurrently fulfill three requirements, that is, an increase in adhesive strength between a fiber sheet and a concrete structure, the thorough impregnation of the inside of the fiber sheet with a resin, and the capability to sufficiently exert strength and an elastic modulus, intrinsic in the fiber sheet.SOLUTION: A bidirectional bicomponent fiber sheet 10 is used in which a warp group fabric 10A and a weft group fabric 10B are different in a fineness and a ridge distance between fiber groups. The one fabric 10B is stuck on a surface of a concrete structure 40 coated with an undercoat resin 51. Subsequently, the other fabric 10A is coated with a top coat resin 52 and impregnated therewith.SELECTED DRAWING: Figure 1
