A vehicle buffer barrier for bridges

Abstract

The invention relates to a vehicle buffer guardrail for bridges, comprising a cross beam and a plurality of vertical bars vertically placed under the cross beam and used to connect the cross beam and the bridge beam body, and further comprising a cross beam placed under the vertical bar and connected to the vertical bars one by one. Corresponding to a plurality of load-bearing rods, the vertical rod includes a vertical column and a tie rod placed vertically above the vertical column; the load-bearing rod slides along the length direction of the load-bearing rod, and the upper end of the bearing rod and the lower end of the vertical column Hinged, the lower end of the load-bearing rod is inclined towards the inside of the bridge, that is, the load-bearing rod is inclined to the outside of the bridge; the upper end of the column is elastically hinged with the lower end of the tie rod, and the upper part of the tie rod is hinged with the beam; , the guardrail not only has the function of blocking, but also can buffer the impact of the vehicle, and at the same time, it can move the center of gravity of the vehicle backward to avoid the vehicle from rolling and falling; the vertical pole is deformed and forms an angle with the load-bearing pole to surround the impact side of the vehicle, effectively preventing the vehicle from flying. Exit the bridge.

Description

technical field [0001] The invention relates to a bridge guardrail, in particular to a vehicle buffer guardrail for a bridge. Background technique [0002] The bridge guardrail is a necessary barrier to protect the safety of vehicles, and its own anti-collision performance and safety protection effect directly affect the safety of driving vehicles; in the prior art, the guardrails on both sides of the bridge are usually simple railings, although they can form a certain However, it is difficult to guarantee the safety of the vehicle under high-speed impact. There are often accidents where the vehicle rolls and falls under the bridge or is thrown away, causing serious damage to the vehicle. Many factors are involved: First, the existing guardrail is in response to the vehicle. The impact is forced to stop, and there is almost no cushioning effect on the impact, so that the vehicle quickly loses control under the impact inertia, causing rollover or throwing; secondly, the exist...

Problems solved by technology

[0003] In view of the above situation, in order to make up for the technical deficiencies existing in the prior art, the present invention provides a vehicle buffer guardrail for bridges to solve the problem of poor buffering effect of the existing bridge guardrails, inability to effectively intervene in the state of vehicle movement, and easy impact on vehicles.
