Bridge anti-collision guardrail

Abstract

The invention discloses a bridge anti-collision guardrail which comprises a base. A placement groove is formed in the upper end of the base. A transverse damping device is arranged at the bottom inside a placement groove, an installing block is arranged at the upper end of the transverse damping device, a clamping device is arranged on the installing block, and one end of the clamping device is fixedly connected to the side wall of one end inside the placement groove. Impact force generated during automobile collision can be converted and offset, the influence caused by automobile collision toa bridge is eliminated, the safety of pedestrians is ensured as much as possible, by combining a vertical rod, a roller, a compression resistance spring and a cross rod, the vertical rod can rotate and deflect during automobile collision so as to resolve the impact force generated by the borne collision, the vertical rod does not need to bear the collision directly, the influence generated by thecollision to the bridge and automobiles is effectively lowered, persons inside automobiles are better protected, the automobiles are made to deflect, it is ensured that the automobiles cannot directly rush out of the bridge, and the guardrail is simple in structure, convenient to operate and suitable for being popularized.

[0002] Bridge guardrail refers to the guardrail set on the bridge. Its purpose is to prevent out-of-control vehicles from getting out of the bridge. Highway grade, comprehensive consideration of its safety, coordination, characteristics of objects to be protected and on-site geometric conditions to determine the anti-collision grade, and then select the structural form according to its own structure, economy, construction and maintenance and other factors, the other There are three ways to embed the column directly, the flange connection type, and the bridge guardrail and the bridge deck through the force-transmitting steel bar. When conditions permit, the removable guardrail can be used, but the current guardrail is in the When a vehicle collides, it generally bears the impact directly, causing the guardrail to bend, deform or even break. This direct impact will cause serious damage to the vehicle and the bridge, and the bridge and vehicle cannot be better protected to ensure the safety of pedestrians. Therefore, we propose a bridge crash barrier to solve the above problems
