Bridge guardrail steel structure with good protection effect
The invention provides a bridge guardrail steel structure with a good protection effect, and relates to the technical field of bridge steel structures. The bridge guardrail steel structure with the good protection effect comprises bases located on the two sides of the top of a bridge, the tops of the bases are provided with fixed cross bars, the two ends of each fixed cross bar are connected with the bridge, a fixed longitudinal rod penetrates through the interior of each fixed cross bar, the bottom of each fixed longitudinal rod is connected with the top of the corresponding base in a clamped mode, and the outer wall of each fixed longitudinal rod is sleeved with a bottom fixing piece and a top fixing piece from bottom to top. According to the bridge guardrail steel structure with the good protection effect, through rotation of an elastic blocking rod with the wind direction, the impact of wind on the bridge can be reduced, and the stability of the bridge is improved; meanwhile, the bases are connected with the fixed cross bars through the fixed longitudinal rods, the stability of a bridge rail is improved, the protection effect is better, when a vehicle is out of control in braking, the vehicle collides with the elastic blocking rod to rotate the elastic blocking rod, the kinetic energy of the vehicle is reduced at the cost of damaging a torsional spring, the speed reduction effect is achieved, and the protection effect of the rail is improved.
本发明提供一种防护效果好的桥梁用护栏钢结构，涉及桥梁钢结构技术领域，该防护效果好的桥梁用护栏钢结构，包括位于桥梁顶部两侧的底座，所述底座的顶部设有固定横栏，且固定横栏的两端均与桥梁连接，所述固定横栏的内部贯穿有固定纵杆，且固定纵杆的底部与底座的顶部卡接，所述固定纵杆的外壁自下而上套设有底部固定件和顶部固定件，该防护效果好的桥梁用护栏钢结构，通过弹性阻杆随着风向进行旋转，可降低桥梁受到风力的影响，提高桥梁的稳定性，同时固定纵杆将底座与固定横栏连接，增加了桥梁栏杆的稳定性，防护效果更佳，在车辆刹车失控时，车辆撞击弹性阻杆使其旋转，以损坏扭簧作为代价降低车辆的动能，起到减速效果，提高栏杆防护效果。
