Description

유리섬유 보강재 및 그 제조장치{Glass fiber reinforcement and manufacturing device thereof}Glass fiber reinforcement and manufacturing device thereof

본 발명은 콘크리트 타설시 보강근으로 사용되는 철근을 대체토록 하는 유리섬유 보강재 및 그 제조장치에 관한 것으로, 더욱 상세하게는 유리섬유 보강재의 표면에 나선형의 유리섬유띠와 함께 산과 골이 단절되는 마디형의 주름을 등간격으로 형성함으로써 콘크리트와의 결합력을 향상시키면서도 유리섬유 보강재를 자동적이고도 연속적으로 제조할 수 있도록 한 것이다.The present invention relates to a glass fiber reinforcing material that replaces reinforcing bars used as reinforcing bars during concrete pouring, and a manufacturing apparatus thereof, and more particularly, to a node type in which mountains and valleys are cut together with a spiral glass fiber strip on the surface of the glass fiber reinforcing material. By forming the corrugations at equal intervals, it is possible to automatically and continuously manufacture glass fiber reinforcement while improving the bonding strength with concrete.

각종 건물이나 교량 등의 건축구조물을 시공시 타설되는 콘크리트 속에는 건축물의 구조, 크기, 하중 등을 고려한 설계에 따라 강도 보강을 위한 철근을 심어 보강근(rebar)으로 사용하는 것이 필연적이다.When constructing a building structure such as various buildings or bridges, it is inevitable to plant rebar for strength reinforcement in the concrete poured in accordance with the design considering the structure, size, and load of the building and use it as a rebar.

이러한 경우 철근은 금속재질로 이루어짐에 따라 콘크리트 속에서 보강근으로 사용되더라도 오랜 시간이 경과되면서 여러 가지 환경적인 요인에 의해 녹이 슬거나 부식되는 등 심각한 현상이 발생되고 있다.In this case, since reinforcing bars are made of metal, even if they are used as reinforcing bars in concrete, serious problems such as rusting or corrosion due to various environmental factors are occurring over a long period of time.

철근의 부식을 방지하기 위하여 철근의 표면에 에폭시를 포함하는 부식방지 재질로 코팅한 것도 제안되어 있으나, 이 역시 염화 콘크리트 환경하에서는 이러한 철근 부식에 따른 문제점을 근본적으로 극복하기는 어려웠다.In order to prevent corrosion of rebar, it has been proposed to coat the surface of rebar with an anti-corrosion material including epoxy, but it was also difficult to fundamentally overcome the problem of rebar corrosion in a chlorinated concrete environment.

이같이 철근에 녹이 슬어 부식되면, 단면적이 감소되면서 강도가 현저히 저하됨으로써 보강재로서 기능을 다하지 못함은 물론이고, 더 나아가 건축물의 높은 하중이나 강한 충격에 의해 감소된 허용 응력의 범위를 초과하여 결국 건물이 무너지게 되는 중대한 문제점이 있었다.As such, when the reinforcing bar is rusted and corroded, the cross-sectional area is reduced and the strength is significantly lowered, so that it cannot function as a reinforcing material. There was a major problem of collapse.

따라서 종래의 문제점 해소하기 위하여 콘크리트 속에 설치되는 철근을 섬유강화 복합소재로 만들어진 일명 유리섬유 보강재로 대체함으로써 내식성, 내열성, 내부식성이 우수할 뿐만 아니라, 철근에 비하여 매우 큰 강도를 가지는 것이 입증되어 전 산업분야에 걸쳐 널리 적용되는 추세에 있고, 반영구적인 신소재로서 그 응용분야도 점차 확대되고 있다.Therefore, in order to solve the conventional problems, by replacing the rebar installed in concrete with a so-called glass fiber reinforcing material made of fiber-reinforced composite material, it is not only excellent in corrosion resistance, heat resistance and corrosion resistance, but also has a very large strength compared to rebar. It tends to be widely applied throughout the industry, and as a semi-permanent new material, the field of application is also gradually expanding.

종래에 제안된 철근대용물을 살펴보면, 이는 대한민국 등록특허 제10-1248933호를 들수 있다.Looking at the conventionally proposed substitute for rebar, this can be mentioned in Korean Patent Registration No. 10-1248933.

이는 강도가 센 유리섬유로빙을 열가소성수지로 압출성형하여 철근대용물을 제조함으로써, 철근에 상응하는 강도를 가지며, 제조가 용이할 뿐만 아니라 배근작업이 용이한 특징을 지닌다.By extruding high-strength glass fiber roving with a thermoplastic resin to manufacture a rebar substitute, it has a strength corresponding to rebar, and is easy to manufacture as well as easy to reinforcing.

그러나 이러한 종래의 섬유강화 복합소재로 만들어진 보강근의 유리섬유 보강재는 다수의 유리섬유 가닥을 묶음으로 권취하여 단순히 봉 형상으로 제작되는 것이기 때문에 콘크리트와 결합시 접착력이 약한 문제점이 있었다.However, since the glass fiber reinforcement material of the reinforcing bar made of such a conventional fiber-reinforced composite material is simply manufactured in a rod shape by winding a plurality of glass fiber strands in a bundle, there is a problem in that the adhesive strength is weak when combined with concrete.

또한 이러한 문제점을 해결하기 위하여 유리섬유 보강재의 외부 표면에 콘크리트와의 결합력을 높이기 위하여 이형철근이라고 불리는 철근과 같이 리브를 일체형으로 형성하는 구조가 제안된 바 있으며, 이는 유리섬유철근의 외표면에 또다른 섬유가닥을 나선형으로 돌출되게 권취시킨 리브를 에폭시 수지로 접착하여 성형한 구성이다.Also, in order to solve this problem, a structure in which ribs are integrally formed like a reinforcing bar called a deformed reinforcing bar has been proposed to increase the bonding force with concrete on the outer surface of the glass fiber reinforcing material. It is a configuration in which ribs in which other fiber strands are wound to protrude in a spiral are bonded to each other with an epoxy resin and molded.

또한 다른 종래의 구조로서는 대한민국 등록특허 제10-1151395호가 제안되어 있다.In addition, as another conventional structure, Korean Patent Registration No. 10-1151395 has been proposed.

이는 일정형상을 가지고, 나선형의 안내골을 형성하는 수지 구조물과, 상기 수지 구조물의 표면에서 상기 나선형의 안내골에 의해 안내되면서 감겨져 굴곡을 형성하여 콘크리트와의 접착력이 증대시키도록 탄소섬유 또는 아라미드 섬유 또는 유리섬유 중 어느 하나의 고강도 섬유재인 강도보강부(리브)를 포함하여 구성된 것이다.It has a certain shape, a resin structure that forms a spiral guide bone, and a carbon fiber or aramid fiber to increase adhesion with concrete by winding while being guided by the spiral guide bone on the surface of the resin structure to form a curve Or it is configured to include a strength reinforcing part (rib) which is a high-strength fiber material of any one of glass fibers.

그러나 상기와 같은 종래의 구조들에서는 유리섬유철근의 외표면에 리브를 에폭시 수지를 이용하여 접착한 구성임으로써 내부식성 및 고강성을 확보할 수는 있으나, 리브의 접착강도를 충분히 유지하지 못하여 지진이나 충격하중 또는 동적하중에 의한 건축물의 진동 발생시 유리섬유철근이 인장되면, 표면의 리브가 쉽게 이탈되어지는 중대한 문제점이 야기될 수 있었다.However, in the conventional structures as described above, corrosion resistance and high rigidity can be secured by bonding the ribs to the outer surface of the glass fiber reinforcing bars using an epoxy resin, but the adhesive strength of the ribs cannot be sufficiently maintained. However, if the glass fiber reinforcing bar is tensioned when vibration of the building occurs due to impact or dynamic load, a serious problem in that the ribs on the surface are easily detached may occur.

즉, 리브가 형성되는 유리섬유철근이 콘크리트에 타설된 후, 여러 가지 요인으로 인하여 유리섬유철근에 강한 인장력이 가해지게 되면, 외표면에 접착된 리브는 콘크리트 속으로 함몰되어 있음에 반해 유리섬유철근은 인장됨으로서 이의 강도를 이기지 못하여 리브가 쉽게 박리되는 중대한 문제점이 있었다.In other words, after the glass fiber reinforcing bars that form the ribs are poured into concrete, when strong tensile force is applied to the glass fiber reinforcing bars due to various factors, the ribs attached to the outer surface are recessed into the concrete, whereas the glass fiber rebars There was a serious problem that the ribs were easily peeled off because they could not overcome their strength as they were tensioned.

이러한 본 발명 유리섬유 보강재(100)의 특징적인 요소는 그 표면에 길이 방향 둘레 나선형의 유리섬유띠(A)가 형성됨과 동시에, 그 내부로 고형의 삽입물을 등간격으로 묻어 길이방향을 따라 산과 골이 단절되는 마디형의 주름(B)들을 일체로 형성토록 하는 것을 포함한다.The characteristic element of the glass fiber reinforcement 100 of the present invention is that a spiral glass fiber strip (A) is formed on its surface in the longitudinal direction, and at the same time, solid inserts are buried therein at equal intervals to form mountains and valleys along the longitudinal direction.
