Abstract

본 발명은 콘크리트 구조물의 보강에 사용되는 강화섬유 시이트에 관한 것으로서, 더욱 상세하게는 접착제층, 지지체층 보강섬유층이 순차적으로 적층되어 있고, 지지체층 아래에 접착제가 국부적으로 코팅되어 있어 수지의 침투성이 우수하고 적은 매수(枚數)로도 많은 보강섬유를 포함하고 있어 보강현장에서 보강효과를 크게 증대시키는 보강용 강화섬유 시이트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing fiber sheet used for reinforcing a concrete structure, more specifically, an adhesive layer and a supporting layer reinforcing fiber layer are sequentially laminated, and an adhesive is locally coated under the supporting layer, Reinforced fiber sheet for reinforcing reinforcing fiber sheet which greatly enhances the reinforcing effect at the reinforcing site because it contains a lot of reinforcing fibers even with a small number of sheets.
