CRASH CUSHION APPARATUS FOR GUARD RAIL END TERMINAL
The present invention relates to a shock absorption device for an end part of a guard rail, absorbing shock with the guard rails upon a collision of a vehicle as the guard rails are sequentially overlapped with each other, so as to reduce a collision speed. According to the present invention, the shock absorption device comprises: a plurality of underground fixing members (100) driven into the ground to be fixed; a post member (200) uprightly installed in the underground fixing members (100) to be able to be individually separated; a shock absorption member (300) allowing the post member (200) to be separated from the underground fixing member (100) at low speed by the shock transferred from the outside to relief the shock when the post member (200) is connected to the underground fixing member (100) to be able to separated; the guard rail (400) fixed in the post members (200) in a state of overlapping one end with the other end; and an elastic coupling member (500) to elastically support between the guard rail (400) and the post member (200) when coupling the guard rail (400) to the post member (200).
본 발명은 차량의 충돌시 방호울타리들이 순차적으로 겹쳐지면서 충격을 완화시켜서 충돌속도를 저감시킬 수 있는 방호울타리 단부 충격흡수장치에 관한 것이다. 본 발명의 특징은, 지중에 박혀서 고정되는 다수의 지중고정부재(100)와, 지중고정부재(100)들에 각각 분리 가능한 상태로 기립되는 기둥부재(200)와, 기둥부재(200)을 지중고정부재(100)에 분리 가능하게 연결한 상태에서, 외부로부터 전달되는 충격에 의해 기둥부재(200)가 지중고정부재(100)에서 저속으로 분리되게 하여 충격을 완화시키는 충격완화부재(300)와, 각각의 일단이 각각의 타단에 겹쳐지는 상태로 기둥부재(200)들에 각각 고정되는 방호울타리(400)과, 방호울타리(400)을 기둥부재(200)에 결합시키는 상태에서 방호울타리(400) 및 기둥부재(200)의 사이를 탄력지지 하는 탄성결합부재(500)를 포함한다.
