Description

차량충돌 완충가드레일{SHOCK-ABSORBING GUARD RAIL OF CARS COLLISION}SHOCK-ABSORBING GUARD RAIL OF CARS COLLISION}

본 발명은 차량충돌 완충가드레일에 관한 것으로서, 특히 전단파괴유도부를 갖는 충격흡수부재에 가로바가 결합되어진 상태로 지주에 볼트결합되어지도록 한 것이다.The present invention relates to a vehicle collision buffer guard rail, in particular to be bolted to the strut in a state in which the horizontal bar is coupled to the shock absorbing member having a shear failure inducing portion.

일반적으로 교량이나 고가도로 등의 차도진행 방향을 따라 양측에 가드레일이 설치되어짐으로써, 차량이 차도를 이탈하는 것을 방지하여 물적, 인적피해의 발생을 예방할 수 있게 된다.In general, guardrails are installed on both sides of a road or a highway, such as a bridge or an overpass, thereby preventing the vehicle from leaving the roadway, thereby preventing the occurrence of physical and human damage.

이러한 가드레일은 통상 차도의 가장자리 또는 중앙에 차량의 진행방향을 따라 일정한 간격을 갖는 지주가 바닥에 직립되게 설치되어지고, 바닥에서 노출된 지주의 상부에 길이방향에 대해 직각되는 방향으로 다수개의 가로보가 설치되어지게 된다. 따라서 차도를 따라 주행하던 차량이 차도를 이탈하여 가드레일에 충돌하면 가로보가 충격에 의하여 변형되면서 충격에너지를 흡수하게 된다.Such guard rails are generally installed so that struts having a predetermined interval along the traveling direction of the vehicle are upright on the floor at the edge or the center of the roadway, and a plurality of crossbeams in a direction perpendicular to the longitudinal direction on the top of the struts exposed from the bottom. Will be installed. Therefore, when the vehicle traveling along the roadway collides with the guardrail by leaving the roadway, the crossbeam is deformed by the impact and absorbs the impact energy.

그러나 가로보에 의하여 흡수되어지는 충격에너지가 한정됨에 따라 차량의 파손과 탑승자의 인명피해가 발생되는 원인이 있었다.However, as the impact energy absorbed by the cross beam is limited, there is a cause of damage to the vehicle and damage to the occupants.

이러한 원인을 해소하기 위한 방안으로 공개특허 10-72726(2006.6.28)호의 방호울타리의 충격완화장치가 제안되었고, 제안된 충격완화장치는 충격완화부재의 내부에 매모리폼이 주름강판에 의하여 상하로 분리된 형태를 갖도록하여 충격을 완화할 수 있으나, 구성부품수의 증가로 인하여 설치 및 유지비용이 증가되는 문제점이 있었다.In order to solve this cause, a shock-absorbing device of the protection fence of the Patent Publication No. 10-72726 (2006.6.28) has been proposed, the proposed shock-relaxing device in the inner side of the shock-absorbing member up and down by the corrugated steel sheet Shock can be alleviated by having a separate form, but there is a problem that the installation and maintenance costs increase due to the increase in the number of components.

한편, 등록특허 10-723028(2007.5.22)호의 차량방호울타리용 충격흡수장치가 제안되었고, 제안된 충격흡수장치는 충격흡수공간의 내면에 요철부와 홈부가 대칭되게 형성되어 충격이 흡수되어지도록 하였으나, 변형되어지는 충격흡수공간 만큼의 충력량만 감당할 수 밖에 없는 문제점이 있었다. 즉, 언더레일에 가해지는 충격량이 감소됨이 없이 바로 충격흡수장치로 전달됨에 따라 피해가 커지는 또 다른 문제점이 있었다.On the other hand, a shock absorbing device for a vehicle protection fence of the Patent No. 10-723028 (2007.5.22) has been proposed, the proposed shock absorbing device is to be symmetrically formed in the inner surface of the shock absorbing space so that the shock is absorbed However, there was a problem that can only bear the amount of shock as much as the shock absorbing space to be deformed. That is, there is another problem that the damage is increased as it is directly transmitted to the shock absorber without reducing the amount of impact applied to the underrail.

본 발명은 구성부품수를 줄여 설치 및 유지비용이 증가되는 것을 방지할 수 있도록 하는 가운데 차량 충돌시 가해지는 충격력이 완충되어질 수 있도록 한 것이다.The present invention is to reduce the number of components to prevent the installation and maintenance costs to increase while the impact force applied in the vehicle crash can be buffered.
