Device that controls and absorbs impact energy by folding for road crush cushion
A folding device for controlling and absorbing impact energy of impact absorption facilities for a road comprises: a guardrail on which a plurality of slits are separated from each other to be arranged; and a pressing member continuously folding a lower portion of a cut hole of the guardrail to the outside in a moving process of the guardrail. Accordingly, impact energy by an impact of a vehicle is primarily absorbed in the moving process of the guardrail, and the impact energy is secondarily absorbed in the process in which the pressing member continuously folds a lower portion of the cut hole of the guardrail to the outside. Therefore, when the present invention is used, the guardrail can sufficiently absorb and control impact energy by an impact of a vehicle in a moving process to eliminate the need for adding separate pipes or buffers for absorbing and controlling impact energy.
본 발명은 복수의 슬릿이 상호 이격되어 배치된 가드레일과, 가드레일의 이동과정에서, 상기 가드레일의 절개홀 아래쪽 부분을 연속적으로 바깥쪽으로 접는 가압부재를 구비한다. 이로 인해, 가드레일의 이동과정에서 1차적으로 차량의 충격에 의한 충격에너지가 흡수되고, 가압부재가 가드레일의 절개홀 아래쪽 부분을 연속적으로 바깥쪽으로 접는 과정에서 2차적으로 충격에너지가 흡수된다. 따라서, 본 발명을 사용하면, 가드레일이 이동과정에서 차량의 충격에 의한 충격에너지를 충분히 흡수하고 조절할 수 있어, 충격에너지를 흡수하고 조절하기 위한 별도의 파이프나 완충재를 추가할 필요가 없다.
