본 발명은 완충 및 탈선방지 가드레일에 관한 것으로, 더욱 상세하게는 별도의 구조물 부가없이 구조적으로 완충작용할 수 있도록 함은 물론 차량이 도로로부 터 이탈하는 것을 방지함으로써 차량 및 인명을 보호하기 위한 것이다.The present invention relates to a cushioning and derailment prevention guard rail, and more particularly, to protect the vehicle and life by preventing the vehicle from leaving the road as well as structurally cushioning without additional structure.

주지하다시피, 가드레일은 교통사고를 예방할 목적으로 통상 낭떠러지나 급커브지점에 설치하는 것으로서, 철재로 된 지주에 레일을 가로방향으로 설치함으로써 차량 충돌시 차량이 전복되거나 추락하는 것을 방지하는 역할을 하게 된다.As is well known, guardrails are usually installed on cliffs or sharp curves to prevent traffic accidents. Rail guards are installed horizontally on steel props to prevent the vehicle from overturning or falling in the event of a vehicle crash. Done.

그런데, 일반적인 가드레일은 구조적으로 완충력이 부족하여 가드레일의 파괴가 심화됨은 물론 차량 및 탑승자에게도 치명적인 충격을 가하게 되며, 가드레일의 완충력이 떨어짐에 따라 가드레일이 차량의 충격을 이기지 못하여 차량이 가드레일 너머로 이탈하거나 추락하는 사고가 빈번하게 발생됨은 주지의 사실이다.However, general guardrails are structurally inadequate in buffering capacity, which intensifies the destruction of guardrails and also causes a fatal impact on vehicles and occupants. It is well known that accidents that break off or fall over rails frequently occur.

본 발명은 이러한 점을 감안하여 제안된 것으로, 금속판의 상부와 하부를 원형으로 절곡하면서 각 단부가 절곡시작부위의 안쪽과 겹쳐지도록 레일을 구성하여 그 중간부를 지주에 볼트를 통해 고정토록 함으로써 차량 충돌시 레일의 상부와 하부에 형성된 원형 절곡부의 각 단부가 안쪽으로 말리면서 완충의 효과를 갖도록 함은 물론 차량이 도로로부터 이탈되는 것을 방지하여 차량 및 탑승자를 원활히 보호할 수 있는 완충 및 탈선방지 가드레일을 제공하고자 하는 것이다.The present invention has been proposed in view of the above points, and by bending the upper and lower parts of the metal plate in a circular configuration, the rails are configured so that each end overlaps with the inside of the bending start portion, and the intermediate part is fixed to the support via bolts to the vehicle collision. Each end of the circular bent portion formed at the upper and lower portions of the sea rail is rolled inward to have a cushioning effect, as well as to prevent the vehicle from being separated from the road, and to protect the vehicle and the occupant smoothly.

Since the flat intermediate portion 21 located between the portions 22 need to be fixed only once to each support 10 by using the bolt 30, installation is also simplified.

레일(20)이 지주(10)에 고정된 상태에서 차량이 충돌되면 레일(20)의 상하부 원형 절곡부(22)가 차량에 먼저 닿게 되며, 각 원형 절곡부(22)는 각각의 단부가 절곡 시작부위의 안쪽면에 겹쳐져 있고 원형으로 절곡되면서 그 안쪽에는 자연스럽게 공간이 형성되므로 차량의 충격에 의해 각 원형 절곡부(22)의 단부가 안쪽으로 말리면서 찌그러지게 되고, 이러한 작용에 의해 차량의 충격이 흡수되어 결과적으로 차량이 정해진 경로, 즉 도로로부터 이탈되는 것을 방지함으로써 차량 및 탑승자를 안전하게 보호해줄 수 있는 것이다.When the vehicle collides while the rail 20 is fixed to the support 10, the upper and lower circular bent portions 22 of the rail 20 come into contact with the vehicle first, and each circular bent portion 22 is bent at each end thereof. The inner surface of the starting portion is overlapped and is bent in a circular shape, so that a space is naturally formed therein, so that the ends of each circular bent portion 22 are curled inward by the impact of the vehicle, and the vehicle is impacted by this action. This can be absorbed and consequently protect the vehicle and the occupant by preventing the vehicle from escaping from the predetermined path, that is, the road.

또한, 각 원형 절곡부(22)의 단부를 그 절곡 시작부위의 안쪽면에 일정길이 겹친 후 용접에 의해 고정한 경우에도 차량의 충격이 발생되면 그 용접부위가 떨어지면서 상기와 동일한 작용을 수행할 수 있게 된다.In addition, even if the end of each circular bending portion 22 is fixed by welding after overlapping a certain length on the inner surface of the bending start portion, when the impact of the vehicle occurs, the welding portion falls and can perform the same function as above. Will be.
