Description
본 발명은 에폭시 수지를 포함하는 콘크리트 구조물 보강용 접착제 조성물 및 이 조성물과 FRP시트 정착단을 이용한 콘크리트 구조물의 인장 정착 보강방법에 관한 것으로서, 보다 상세하게는 콘크리트 구조물, 예를 들면 콘크리트 구조물의 단부 등을 FRP시트로 감싸 인장하여 정착된 FRP시트 정착단을 부착하여 콘크리트 구조물을 인장 정착 보강하기 위한 에폭시 수지를 포함하는 콘크리트 구조물 보강용 접착제 조성물 및 이 조성물과 FRP시트 정착단을 이용한 콘크리트 구조물 인장 정착 보강방법에 관한 것이다.The present invention relates to an adhesive composition for reinforcing concrete structures containing an epoxy resin and a tensile anchorage reinforcement method for concrete structures using this composition and FRP sheet anchorage ends. More specifically, it relates to concrete structures, for example, ends of concrete structures, etc. An adhesive composition for reinforcing concrete structures containing an epoxy resin for tensile and anchoring reinforcement of a concrete structure by attaching an FRP sheet anchoring end that is tensile and anchored by wrapping it with an FRP sheet, and tensile and anchoring reinforcement of a concrete structure using this composition and an FRP sheet anchoring edge. It's about method.
일반적으로 시행해오던 콘크리트 구조물의 보강방법은, 콘크리트 구조물의 단부 외면에 돌출 설치된 고정부재를 이용하여 강선을 긴장하는 것이다.A commonly used method of reinforcing concrete structures is to tension steel wires using fixing members protruding from the outer surface of the end of the concrete structure.
그런데 이와 같은 종래의 보강방법에서는 콘크리트 구조물의 외면에 고정부재가 돌출되므로 보강 후 구조물의 외관이 나빠지는 단점이 있다. 또한 고정부재가 돌출되어 설치될 만한 공간이 반드시 확보되어야 하므로, 콘크리트 구조물의 보강 대상면이 이웃한 구조물과 바로 인접해 있는 경우와 같이 콘크리트 구조물의 보강 대상면에 고정부재를 돌출 설치할 공간이 충분하지 못한 경우에는 적용할 수 없다는 한계가 있다.However, this conventional reinforcement method has the disadvantage of deteriorating the appearance of the structure after reinforcement because the fixing member protrudes from the outer surface of the concrete structure. In addition, space must be secured for the fixing member to protrude and be installed, so there is not enough space to protrude and install the fixing member on the reinforced surface of the concrete structure, such as when the reinforced surface of a concrete structure is immediately adjacent to a neighboring structure. There is a limitation in that it cannot be applied in cases where it is not possible.
특히, 교량의 콘크리트 빔에서는 콘크리트 빔의 하면에 고정부재를 이용하여 긴장재를 설치하게 되면 그만큼 콘크리트 빔의 하부 공간을 차지하게 되고, 그에 따라 교량의 높이가 낮아지게 되는 문제점이 발생하게 된다.In particular, in the concrete beam of a bridge, if a tension member is installed on the lower surface of the concrete beam using a fixing member, the lower space of the concrete beam is occupied, which causes the problem of lowering the height of the bridge.
상기 고정부재는 주로 금속재로 만들어지는데 콘크리트 구조물의 외부에 설치되어 강우 등으로 인하여 지속적으로 수분에 노출되므로 고정부재가 쉽게 부식될 수 있으며, 이 경우 녹물이 흘러 콘크리트 구조물의 외관을 해치는 것은 물론이고 고정부재의 파손이 발생하여 긴장재의 긴장이 해체될 수도 있다. The fixing member is mainly made of metal, and is installed on the outside of the concrete structure and is continuously exposed to moisture due to rain, etc., so the fixing member can easily corrode. In this case, rust flows and not only damages the appearance of the concrete structure, but also fixes it. Damage to the member may occur and the tension in the tendon may be dissolved.
이러한 고정부재의 손상은 결국 콘크리트 구조물의 보강력 손실을 가져와서 궁극적으로는 구조물의 파괴를 야기할 수도 있게 된다. Damage to these fixing members can ultimately lead to loss of reinforcing strength of the concrete structure, ultimately leading to destruction of the structure.
