The invention relates to a vehicle buffer guardrail for a bridge, which comprises a cross beam and a plurality of vertical rods which are vertically arranged below the cross beam and used for connecting the cross beam with a bridge body, and further comprises a plurality of bearing rods arranged below the vertical rods and in one-to-one correspondence with the vertical rods, and each vertical rodcomprises a vertically arranged stand column and a vertically arranged pull rod arranged above the upright post; the bearing rods slide in the length direction of the bearing rods, the upper ends of the bearing rods are hinged to the lower ends of the stand columns, and the lower ends of the bearing rods face the inner side of the bridge, namely the bearing rods incline towards the outer side of the bridge. The upper ends of the stand columns are elastically hinged to the lower ends of the pull rods, and the upper portions of the pull rods are hinged to the cross beam. When vehicle collision occurs, the guardrail not only has a blocking function, but also can achieve buffering of vehicle collision, meanwhile, the gravity center of a vehicle can be moved backwards, and the vehicle is prevented from rolling and falling off; after deformation, the vertical rods and the bearing rods form included angles to surround the impact sides of vehicles, and the vehicles are effectively prevented from flying out of the bridge floor.
本发明涉及一种用于桥梁的车辆缓冲护栏，包括横梁和竖向置于横梁下方的用于连接横梁与桥梁梁体的多个竖杆，还包括置于竖杆下方并与竖杆一一对应的多个承重杆，所述的竖杆包括竖向设置的立柱和置于立柱上方竖向设置的拉杆；所述的承重杆沿承重杆的长度方向滑动，承重杆的上端与立柱的下端铰接，承重杆的下端朝向桥梁内侧方向即承重杆向桥梁外侧方向倾斜设置；所述的立柱的上端与拉杆的下端弹性铰接，所述的拉杆的上部与横梁铰接；本发明使车辆撞击发生时，护栏不仅具备阻挡功能，还可以实现对车辆撞击的缓冲，同时可以使车辆重心后移，避免车辆翻滚跌落；竖杆变形后与承重杆形成夹角可以将车辆撞击侧包围，有效避免车辆飞出桥面。
