Novel safety guardrail structure for highway bridge
The invention belongs to the technical field of guardrails, and particularly relates to a novel highway bridge safety guardrail structure which comprises a base. A fixed seat is embedded and mounted at the top end of the base, a protective rod is mounted at the top end of the fixed seat, protective plates connected with the protective rod are arranged on the two sides of the protective rod, a protective bag is arranged at the protective rod, and an inflation nozzle is mounted on the protective bag; the protective bags play a role in buffering a collided vehicle after bulging, stress concentration of the guardrail can be reduced, meanwhile, the protective bags can rotate relative to the protective rods when being collided, and therefore the advancing direction of the vehicle can be changed to a certain degree, the vehicle can advance in the length direction of the guardrail, and the safety of the vehicle is improved. Therefore, the situation that the guardrail deforms seriously or is directly knocked over when a vehicle vertically applies acting force to the guardrail is reduced, the risk that the vehicle falls from a bridge is reduced, meanwhile, the protective bags are convenient to replace and install when damaged, and the practicability of the guardrail structure is improved.
本发明属于护栏技术领域，具体的说是新型公路桥梁用安全护栏结构，包括基座；所述基座顶端镶嵌安装有固定座，所述固定座顶端安装有防护杆，所述防护杆两侧设有与之相连的防护板，所述防护杆处设有防护囊，所述防护囊上安装有充气嘴；本发明中的防护囊在鼓起后对撞击的车辆起到缓冲的效果，且能减少护栏的应力集中，同时防护囊在被撞击时会相对于防护杆发生转动，从而能够一定程度的改变车辆的行进方向，使得车辆能够贴着护栏的长度方向行进，从而减少车辆垂直对护栏施加作用力时，导致护栏变形严重或直接被撞翻的情况，减少车辆从桥梁上坠落的风险，同时防护囊在损坏时也便于更换与安装，提高了护栏结构的实用性。
