개량형 철도교량 리모델링 구조 및 이의 시공방법{Improved Rail Road Bridge Remodeling Structure And Construction Method thereof} Improved Rail Road Bridge Remodeling Structure And Construction Method

본 발명은 철도교량의 리모델링 과정에서 폐기되던 판형거더를 재활용하되, 공장제작된 PC슬래브를 설치하여 시공성 및 구조적안정성이 우수한 개량형 철도교량 리모델링 구조 및 이의 시공방법을 제공한다.
The present invention provides an improved railway bridge remodeling structure and its construction method which is excellent in workability and structural stability by installing a factory-produced PC slab, while recycling the plate-shaped girder that was discarded in the remodeling process of the railway bridge.

도 2는 종래의 철도교량을 도시한 것이다.2 shows a conventional railway bridge.

도시된 바와 같이 현재 철도교량의 대부분을 차지하고 있는 기존의 판형교는 판형거더(100) 위에 목재로 제작한 침목(20)만을 설치하고, 그 위에 철도레일(10)이 설치된 구조형식(무도상 시스템)이 대부분을 차지하고 있다.As shown, the existing plate-shaped bridge, which currently occupies most of the railway bridge, installs only the sleepers 20 made of wood on the plate-shaped girder 100, and the structural type (railless system) in which the railroad rail 10 is installed thereon. ) Occupy most of it.

그리고 근래에는 철도차량의 고속화에 따라 기존의 판형교에서 고속차량에 통과에 따른 추가적인 구조적 안정성이 요구되고 있으며, 무도상 철도교(목재침목 교량)를 유도상화 시스템(연속슬래브)으로 전환되는 과정에 있다.Recently, due to the high speed of railroad cars, additional structural stability is required by passing high-speed cars from existing plate-shaped bridges, and in the process of converting non-free railroad bridges (wooden sleeper bridges) into induction systems (continuous slabs). .
