강화성 수지섬유와 결합한 구조물의 강성 보강재{omitted}Rigid reinforcement of structures combined with reinforced resin fibers

본발명은 콘크리트 구조물의 받침이나 건축물의 거푸집은 물론 교량의 수중교각, 수심부의 부식, 파손, 파열된 부분을 보수, 보강하고 더 나아가서 터널의 표면거푸집 겸 커버에 사용케 하기위한 견고한 강화성 수지섬유와 결합한 구조물의 강성 보강재에 관한 것이다The present invention is a strong reinforcing resin fiber for repairing and reinforcing concrete bridges, formwork of buildings as well as underwater bridges of bridges, corrosion, breakage, and rupture of the depths, and further for surface formwork and cover of tunnels. To rigid stiffeners of structures in combination with

종래에는 본원과 분할된 출원제 10-2000-0065669호의 분할출원으로서 상기 출원은 FRP 보강재에 철망을 형성하고 내외 수지층과 주앙수지층으로 구성하여 플랜지를 돌출한 패널의 보강재에 있어서, 탄소섬유층을 구성하여 중앙에 촙스트랜드 매트층과 경화수지를 대체한 보강재인 보론섬유층을 형성한 것과 내향면에 보론섬유층의 외향면으로 굵은 철망을 내삽 구성하여 FRP 커버가 수중에서 크랙이되어서 모래, 자갈 등과 유속의 타격에의해 파손되는 결함을 고강성으로 보강구성한 것으로서 이는 고강성에 견디는 보강력은 아주 양호하다 그러나 몇가지 문제가 따른다Conventionally, the divided application of Korean Patent Application No. 10-2000-0065669, which is divided from the present application, forms a wire mesh in an FRP reinforcement, and consists of an internal and external resin layer and a central resin layer, and includes a carbon fiber layer in a reinforcing member of a panel protruding a flange. By forming a boron fiber layer, which is a reinforcing material replacing the stranded mat layer and cured resin in the center, and inserting a coarse wire mesh into the outward surface of the boron fiber layer on the inward side, the FRP cover is cracked in the water so that the flow rate of sand, gravel, etc. It is a reinforcement structure of defects that are damaged by hitting with high stiffness. The reinforcement to withstand high stiffness is very good but there are some problems.

즉, 이것은 철망의 망판을 한겹 또는 두겹으로 내삽,구성하기위하여는 철망판의 강성에의한 탄력으로 인해 원하는 형상을 성형하기 위하여는 만곡시킬 경우 잡아주어야 하는 문제가 따르고 잡아준 망상 외주면으로 수지층을 도포하기 위해서는 번거롭고 복잡한 작업 과정을 거쳐야 하고 또 성형후에는 철망판의 중량으로인하여 보강재 및 커버 도는 거푸집의 무개가 증가하여 대형의 보강제나 거푸집을 현장으로 이동, 운반하거나 적재, 보관은 물론 설치작업등에 상당한 어려움이 있고 특히 이로인한 경비의 과다 소요가 따르는 문제가 있었던 것이다That is, in order to interpolate and construct the mesh of the mesh in one or two layers, the resin layer is placed on the outer circumferential surface of the mesh, which is a problem to be caught in order to form a desired shape due to the elasticity due to the rigidity of the mesh. In order to apply, it has to go through a cumbersome and complicated work process. After molding, the weight of the mesh panel increases the weight of the reinforcement and cover or formwork. There was considerable difficulty, especially with the overexpenditure of expenses.

본발명은 이와같은 종래의 문제점을 근본적으로 해결 및 보완하고 성형후 견고하면서 성형작업시 작업이 원활하고 중량이 가벼원서 이동, 운반, 적재, 보관, 취급 및 설치작업이 용이하게 철망판을 제외하고, 아라미드섬유를 수지층 중단에 삽입층으로 구성하고 또 아라미드섬유와 철망을 함께 삽입, 구성하므로서 시용성과 경제성의 목적을 모두 충족시키고 거푸집으로서의 커버를 터널 공법에도 이용할수 있도록 분할 하게된 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다The present invention fundamentally solves and complements such a conventional problem, and it is robust after molding, and the work is smooth and light in molding, except for the mesh panel, which is easy to move, transport, load, store, handle and install. In addition, the aramid fiber is composed of an insertion layer at the end of the resin layer, and the aramid fiber and the wire mesh are inserted and configured together to satisfy both the purpose of the application and economic feasibility and to divide the cover as a form to be used for the tunnel construction method. If described in detail as follows:

도 1 은 본발명의 아라미드섬유를 내삽 몰딩한 상태를 발체한 예시도1 is an exemplary view showing the state in which the interpolated molding of the aramid fibers of the present invention

도 2 는 본발명의 아라미드서유를 내삽한 상태의 단면예시도Figure 2 is a cross-sectional view of the state in which the aramid standing oil of the present invention interpolated

도 3 은 본발명의 아라미드섬유와 철망을 내삽한 단면예시도Figure 3 is an exemplary cross-sectional view interpolating the aramid fiber and the wire mesh of the present invention

철망층(6)을 내삽하고 불포화 폴리에스텔수지층 및 에폭시수지층으로 형성하여 구성한 보강재에 있어서, 외향면에 겔코트수지층(3)과 촙스트랜드매트층(3') 및 내향면에 촙스트랜드층(2)과 에폭시수지층(2')을 형성한 중앙에 철망(7)과아라미드섬유층(9)을 보강심재로 하거나 아라미드섬유층(9)단독으로 보강심재로 구성함을특징으로 한것이다In the reinforcing material formed by interpolating the wire mesh layer 6 and forming an unsaturated polyester resin layer and an epoxy resin layer, the gel coat resin layer 3 and the chopped strand mat layer 3 'on the outward surface and the chopped strand on the inward surface are constructed. It is characterized in that the wire mesh 7 and the aramid fiber layer 9 are used as the reinforcing core or the aramid fiber layer 9 is made of the reinforcing core alone in the center where the layer 2 and the epoxy resin layer 2 'are formed.

이의 작용을 설명하면 다음과같다The explanation for this is as follows.

도 1 과 도 2 에 도시한것에 의하여 설명하면 보강재 패널의 일부를 발췌한 확대사시도와 확대단면 예시도로서 FRP에 철망판을 하나와 두 개를 삽입하고 내외 와 중앙에 수지층을 구성하여 형성하거나 탄소섬유층, 촙스트랜드매트층 보론섬유층 등으로 구성한 출원분할된 것은 예를들어 교량의 교각 기초우물통 보수보강재로 이용하거나 거푸집, 형틀등으로 이용할 경우 철판보다 강하고 기존 FRP 보다 2배이상 강하고 견고하여 수중구조물을 장기간 유지 보존시키는 것에 적합하지만 주량의 무거움으로 인한 문제점이 있는 것과는달리 외향면에 로빙크로스 또는 촙스랜드층(2)과 에폭시수지층(2')을, 반대쪽 내항면에는 겔코트수지층(3)과 촙스트랜드매트층(3')을 구성하는 사이에 아라미드섬유층(9)을 형성케 함으로서 상기한 철망판을 이중으로 구성한 것과 같은 견고성을 유지하는 반면 중량이 월등히 가벼원서 제조성형후 이동, 운반, 적층, 설치작업등에 따르는 취급과 사용이 극히 경제적인 이점이 있게된다1 and 2 illustrate an enlarged perspective view and an enlarged cross-sectional view of a part of the reinforcement panel, and inserting one and two wire mesh panels into the FRP and forming a resin layer at the inside and at the center. The divided application consisting of carbon fiber layer, chopped strand layer and boron fiber layer is used as repair reinforcement for bridge wells of bridges or formwork, form, etc. It is suitable for long-term preservation of the structure, but unlike the problem caused by the heavy weight, the roving cross or hicksland layer (2) and the epoxy resin layer (2 ') on the outward surface and the gel coat resin layer on the opposite inner surface ( The above-mentioned wire mesh board is doubled by forming an aramid fiber layer 9 between 3) and the strand strand mat layer 3 '. While maintaining the same robustness, the weight and weight are extremely light, so the handling and use by moving, transporting, laminating, and installing after manufacturing molding are extremely economical.

도 3의 예시단면은 아라미드섬유층(9)사이에 철망판(7)을 삽입하여 견고성을 더욱 강조한 것으로서 중량은 다소 무거우나 금속망(7)단독의 삽입이나 아라미드섬유층(9) 단독 삽입 구성하는 것에 비하여 견고성은 약 50%이상 증대되며, 아라미드섬유층(9)을 보강심재로 한 것은 터널내의 거푸집 겸용 커버로 사용함에 이상적이고 강을 건너는 교량의 교각에 사용하는 것보다 염분을 함유한 바다위의 교량에 설치한 교각의 수중구조물 보강재로서 아라미드섬유층(9)단독으로 구성된 본원분할의 구성이 적합하다The example cross-section of FIG. 3 shows that the wire mesh plate 7 is inserted between the aramid fiber layers 9 to further enhance the rigidity, but the weight is rather heavy, but the metal mesh 7 is inserted alone or the aramid fiber layer 9 is inserted alone. Compared to the above, the robustness is increased by more than 50%, and the aramid fiber layer 9 is used as a reinforcing core material in the tunnel, which is ideal for use as a formwork cover in the tunnel, and it is a bridge on the sea containing salt than it is used for the bridge pier crossing the river. The construction of the main division consisting of the aramid fiber layer (9) alone is suitable as the reinforcement material for the piers installed in the bridge.

아라미드섬유층(9)을 보강심재로 구성하면 금속망판을 이중심재로 구성한것과 비교하면 마모와 파손을 저지하는 작용은 거의 유사하다 중량이 가볍고 판넬이나 거푸집, 터널에사용하는거 푸집겸용 커버로 성형시 작업이 용이하고 사용이편리한 이점이 있다When the aramid fiber layer (9) is composed of reinforcing core material, the effect of preventing abrasion and damage is almost similar to that of the metal mesh board composed of double core material. It is light in weight. This has the advantage of being easy and easy to use

이와같이된 본발명은 중량이 가볍다는 장점외에 터널공법에 사용하는 거푸집겸 커버로도사용할수 있고 제작,성형작업이 쉬워서 경제적이며 강성저하, 충돌파괴, 변형구속 성능등을 향상시키고 유기물 섬유의 내삽으로 철판보다 내마모성, 내부식성이 우수한 효과적인 것이다In addition to the advantages of light weight, the present invention can be used as a formwork and cover for tunneling, and is easy to manufacture and mold, which is economical and improves rigidity, impact destruction, deformation restraint performance, and iron plate by interpolation of organic fiber. More effective in wear resistance and corrosion resistance
