본 발명은 프리스트레스트 콘크리트 침목 탈선방지용 가드레일 체결장치에 관한 것으로, 특히 선로의 급곡선부에 열차의 속도와 원심력에 의해 급곡선부 외측으로 밀려 탈선 및 전복을 방지할 수 있도록 한 프리스트레스트 콘크리트 침목 탈선방지용 가드레일 체결장치에 관한 것이다.The present invention relates to a guardrail fastening device for preventing derailment of prestressed concrete sleepers, and in particular, prestressed concrete sleepers which are prevented from derailment and overturning by being pushed out of the rapid curve by the speed and centrifugal force of the train in the curve of the track. It relates to a guardrail fastening device for preventing derailment.

일반적으로 레일체결장치는 급곡선부의 레일 하측으로 평판상의 베이스플레 이트가 설치되고, 상기 레일 일측에는 레일 일단을 지지 고정하는 레일브레이스가 코일스프링으로 지지되도록 고정 설치되며, 상기 레일의 타측에는 이와 일정한 간격 이격되어 가드레일이 코일스프링을 매개로 하여 설치되도록 구성됨을 특징으로 한다.In general, the rail fastening device is installed on the base plate of the flat plate on the lower side of the rail of the curved curve, the rail is fixed to one side of the rail to support the rail end is supported by the coil spring, the other side of the rail is fixed to this The spaced apart guard rail is characterized in that it is configured to be installed via the coil spring.

상기한 바와 같은 구성으로 이루어진 종래의 레일체결장치는 철도 선로의 급곡선부상에 레일 지지부인 침목 상에 베이스플레이트를 개재하여 그 상측으로 레일이 설치되고, 상기 레일의 일측면으로 레일 브레이스가 위치되어 레일의 일측면이 밀리지 않도록 지지 고정하며, 상기 레일 브레이스는 베이스플레이트에 코일스프링을 이용하여 고정된다.In the conventional rail fastening device having the configuration as described above, the rail is installed to the upper side through the base plate on the sleeper that is the rail support on the sharp curve of the railway track, and the rail brace is located on one side of the rail. One side of the rail is fixed to prevent pushing, and the rail brace is fixed to the base plate using a coil spring.

한편, 상기 레일의 타측면인 레일 브레이스와 대향하는 반대측에는 가드레일이 위치되어 상기 레일과 일정한 간격 이격되는 상태로 설치된 후, 이를 코일스프링을 이용하여 고정함으로써, 선로의 급곡선부를 통과하는 열차의 차륜은 가드레일에 안내되고, 열차의 하중과 횡압을 많이 받는 레일은 레일브레이스에 지지되는 상태로 된다.On the other hand, the guard rail is located on the opposite side facing the rail brace that is the other side of the rail is installed in a state spaced apart from the rail, and fixed by using a coil spring, the train passing through the sharp curve of the track The wheels are guided by the guard rails, and the rails subjected to a lot of loads and lateral pressures of the train are supported by the rail brakes.

그러나 상기와 같은 선로의 급곡선부에서는 열차의 속도와 원심력이 비교적 크게 작용하며, 상기 원심력에 의한 횡압으로 열차가 레일 외측으로 밀리게 됨에 따라 열차의 탈선 및 전복의 우려가 상존하는 단점이 있다.However, the speed and the centrifugal force of the train is relatively large in the sharp curve portion of the track as described above, and as the train is pushed to the outside of the rail due to the transverse pressure caused by the centrifugal force, there is a problem of derailment and overturning of the train.

특히, 상기한 선로 급곡선부의 열차 차륜이 안정적으로 안내되도록 레일의 일측으로 별도의 가드레일을 설치하고, 상기 레일의 일측면에는 레일브레이스를 체결함으로써, 가드부의 구조가 복잡하고, 이에 따라 제작 및 설치가 어려우며, 설치 비가 증가되는 등 많은 문제점을 내포하고 있다.In particular, by installing a separate guard rail on one side of the rail so as to stably guide the train wheels of the track sharp curve portion, and fastening the rail brake on one side of the rail, the structure of the guard part is complicated, and accordingly It is difficult to install and includes many problems such as increased installation ratio.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, PC침목 상에 별도의 베이스플레이트를 설치할 필요없이, PC침목에 코일스프링클립걸이와 매립형 걸림쇠를 설치하여 곡선부 구간에 열차의 탈선 및 전복을 방지하도록 한 프리스트레스트 콘크리트 침목 탈선방지용 가드레일 체결장치를 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the problems described above, without installing a separate base plate on the PC sleeper, by installing a coil spring clip hook and a buried type latch on the PC sleeper train in the curved section The purpose of the present invention is to provide a guardrail fastening device for preventing derailment of prestressed concrete sleepers to prevent derailment and overturning.
