기차가 레일 위를 안전하게 달릴 수 있도록 레일을 고정시키고 레일에 걸리는 등분포 하중을 도상 및 노반으로 고르게 분포시켜 주는 역할을 하는 침목 은 나무를 시작으로 PC 침목을 이용하고 있다.The sleepers, which fix the rails so that the train can run safely on the rails and distribute the equally distributed loads on the rails to the roadbed and the roadbed, use PC sleepers, including trees.

나무 침목은 오래가지 않아 부식되고 PC 침목도 표면이 보호되지 않아 부식 또는 균열이 발생되어 정해진 내구연한 안에 교체하여야 할 문제점을 갖게 되었다. 이에 반하여 본 고안은 인장력에는 약하지만 압축력에는 강한 콘크리트의 약점을 보완한 구조용 각형강관 PC(Prestressed Concrete) 침목은 양측면이 강선 통과 구멍이 뚫린 맹판으로 막힌 구조용 각형강관 속에 여러 개의 강선을 넣고 잭을 이용하여 인장한 상태에서 구조용 각형강관 상부 구멍으로 콘크리트를 흘려 넣어 제작한 후에 콘크리트를 타설하고 구조용 각형강관 상부 구멍을 용접하여 덮는다.Wooden sleepers do not last long enough to corrode, and PC sleepers also do not protect the surface, causing corrosion or cracking, which has a problem of being replaced within a predetermined durability. On the contrary, the present invention is a structural square steel tube PC (Prestressed Concrete) sleeper that compensates for the weakness of concrete that is weak in tensile strength but strong in compressive strength. After the concrete is poured into the upper part of the structural square steel pipe in the tensioned state, the concrete is poured and the upper hole of the structural square steel pipe is welded and covered.

Bend and fix the nail and finish FRP secondary lamination again, and the entire surface of the composite sleeper is completely attached to FRP and does not corrode, resulting in semi-permanent composite sleeper.

본 고안은 상기한 종래 문제 기술의 문제점을 해소하기 위해 안출된 것으로 침목 제작시 합성구조(FRP+구조용 각형강관+강선+콘크리트)로 제조하기 때문에 구조용 각형강관 속에 강선을 넣고 콘크리트를 타설하여 인장력을 보강하고 PC 침목의 균열 및 부식을 방지하게 되고 그 위에 일정한 간격으로 앵커 못을 용접하여 부착하고 레일 체결 장치를 좌우 레일 밑 구조용 각형강관과 용접하여 붙인 다음 육면체의 표면에 프라이머를 도포하고 FRP 1차 적층하여 FRP 중창막을 형성하고 앵커못을 구부려 고정하고 그 위에 다시 FRP2차 적층 마무리하여 부착력이 증대되어 견고하고 안전하며 레일 체결 장치가 구조용 각형강관에 완벽하게 용접 부착되어 시공성이 우수한 합성구조 침목을 제공하는데 있다. The present invention was devised to solve the problems of the above-described conventional problem technology, so that the sleeper is manufactured with a composite structure (FRP + structural square steel pipe + steel wire + concrete), so that steel wire is placed in the structural square steel pipe to reinforce the tensile force. To prevent cracking and corrosion of PC sleepers, and to weld anchor nails at regular intervals on them, and to attach rail fastening devices to the square steel pipes under the left and right rails. FRP midsole film is formed and the anchor nail is bent and fixed, and the FRP 2nd lamination finish is again applied to increase the adhesive force, and the rail fastening device is completely welded and attached to the structural square steel pipe to provide a composite structural sleeper with excellent constructability. have.

본 고안은 합성구조물 침목으로서 콘크리트의 부식이나 인장력을 증대시켜 구조물의 안전과 내구년한을 반영구적인 구조물로 향상시킬 수 있는 것을 특징으로 한다.The present invention is characterized by improving the safety and durability of the structure as a semi-permanent structure by increasing the corrosion or tensile force of the concrete structure sleeper.
