Box type bridge safety guardrail structure
The invention discloses a box type bridge safety guardrail structure. Thebox type bridge safety guardrail structure comprises edge beams arranged at the ends of flange plates and extending in the driving direction and further comprises concrete rigid guardrails integrally formed with the edge beams. A rubber buffer layer is arranged on the surface of the concrete rigid guardrail and fixed to the guardrail through split bolts. According to the guardrail structure, the edge beam structure can remarkably improve the overall rigidity of the flange plate of the box type bridge and enlarge the load distribution area of the flange plate, so that the safety and economical efficiency of the guardrail structure are improved; the rubber buffer layer outside the guardrail can effectively reduce the impact force generated when an unstable vehicle collides with the guardrail, the collision protection effect on the guardrail and the vehicle is enhanced, meanwhile, the rubber buffer layer is fixed to the guardrail through the split bolts, and disassembly, assembly and replacement are convenient.
本发明公开了一种箱型桥梁安全护栏结构，所述护栏结构包括设置在翼缘板端部且沿着行车方向延伸的缘梁，还包括与缘梁一体成型的混凝土刚性护栏；所述混凝土刚性护栏表面设有橡胶缓冲层，橡胶缓冲层通过对拉螺栓固定在护栏上。本发明护栏结构中缘梁结构可显著提高箱型桥梁翼缘板整体刚度，扩大翼缘板荷载分配面积，从而提高护栏结构的安全性和经济性；护栏外的橡胶缓冲层能够有效降低失稳车辆撞击护栏的冲击力，增强对护栏和车辆的碰撞保护作用，同时橡胶缓冲层通过对拉螺栓固定在护栏上，拆装更换方便。
