FRP Structure and Method for Reinforcing Concrete Member using Steel Wire Embedded FRP bar
The present invention relates to a method and structure to reinforce a concrete structure by separated anchoring of a fiber reinforced plastic (FRP) rebar using a buried steel wire and a fixed anchoring device, and a concrete structure reinforced thereby. According to the present invention, while a concrete structure is reinforced by installing an FRP rebar, a buried steel wire buried in the FRP rebar is easily bound and fixed to a fixed anchoring device protruding from a reinforced surface of the concrete structure, and thus installation of the FRP rebar is able to be efficiently performed. Moreover, the FRP rebar is disposed in a shape of being spaced apart from the reinforced surface of the concrete structure, such that integration between the FRP rebar and a coating member is able to be reinforced when the coating member is coated on the reinforced surface of the concrete structure, bending strength is able to be improved, and separation of an end part of the FRP rebar is able to be prevented, thereby being able to maximize reinforcement effect by the FRP rebar for the concrete structure.
본 발명은 콘크리트 구조물에 FRP 보강근을 설치하여 보강하되, FRP 보강근 내에 매립되어 있는 매립강선을 콘크리트 구조물의 보강면에 돌출 구비된 고정 정착구에 용이하게 결속하여 고정시킴으로써 FRP 보강근의 설치작업을 효율적으로 수행할 수 있게 되며, 더 나아가 FRP 보강근이 콘크리트 구조물의 보강면으로부터 이격된 형태로 배치되도록 함으로써 콘크리트 구조물의 보강면에 피복부재를 피복 형성할 때 FRP 보강근과 피복부재간의 일체화를 더욱 강화시키며 휨강성을 더욱 향상시키고 FRP 보강근의 단부 박락을 방지함으로써 FRP 보강근에 의한 콘크리트 구조물의 보강효과를 극대화시킬 수 있는 콘크리트 구조물의 보강방법과 보강구조, 그리고 이에 의하여 보강된 콘크리트 구조물에 관한 것이다.
