본 발명은 가드레일에 미리 결정된 간격에 따라 상호 이격되어 배치되는 복수의 절개홀이 길이방향으로 형성되며, 가압부재가 서로 이웃하는 절개홀 사이에 배치된 브릿지면을 연속적으로 절단하고 절단된 브릿지면을 바깥쪽으로 절곡시킨다. 이로 인해, 가드레일의 브릿지면의 절단에너지만큼 충격에너지가 1차적으로 흡수되고, 가드레일의 브릿지면의 절곡에너지만큼 충격에너지가 2차적으로 흡수된다. 따라서 본 발명을 사용하면, 절단에너지와 절곡에너지를 융합하여 가드레일이 이동하는 과정에서 차량의 충격에 의한 충격에너지를 충분히 흡수할 수 있고, 절단에너지 및 절곡에너지를 조절하여 충격에너지 흡수량을 다양하게 조절할 수 있다.
According to the present invention, a plurality of cutting holes spaced apart from each other at predetermined intervals are formed on a guardrail in a longitudinal direction, and a pressing member continuously cuts a bridge surface disposed between adjacent cutting holes and bends the cut bridge surface outward. Accordingly, impact energy is primarily absorbed by an amount equivalent to cutting energy of the bridge surface of the guardrail, and impact energy is secondarily absorbed by an amount equivalent to bending energy of the bridge surface of the guardrail. Therefore, by using the present invention, it is possible to sufficiently absorb the impact energy due to the impact of a vehicle in a process of moving the guardrail by fusing the cutting energy and the bending energy, and the amount of impact energy absorption can be variously adjusted by adjusting the cutting energy and the bending energy.
