Anti-collision structure of road bridge

Abstract

The invention relates to an anti-collision structure of a road bridge, and belongs to the technical field of anti-collision structures. The anti-collision structure comprises an upright post, whereinthe upright post is fixedly connected to the ground; the upright post is fixedly connected with a horizontal cross bar; the cross bar is provided with an impact transfer assembly; the impact transferassembly comprises a vertical rod and a connecting ring; the vertical rod is hinged at the bottom of the cross bar; the hinge axis of the vertical rod is parallel to the length direction of the crossbar; the vertical rod is vertically arranged; the connecting ring is embedded in the ground; the bottom of the vertical rod is hinged to the connecting ring; and a buffer is fixedly connected betweenthe cross bar and the upright post. The anti-collision structure has the effect of reducing the damage possibility of the post and improving the vehicle protection capability.

Description

technical field [0001] The invention relates to the technical field of anti-collision structures, in particular to an anti-collision structure for road bridges. Background technique [0002] At present, with the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are currently the most frequent occurrences in road sections or highway bridge sections. In order to reduce traffic accidents, various guardrails are installed on both sides of the road. [0003] The existing anti-collision structure usually consists of pillars vertically erected to the ground and horizontal bars perpendicular to the pillars. [0004] The above-mentioned existing technical solutions have the following defects: when being hit by an out-of-control vehicle, most of the impact energy applied to the railing is directly transmitted to the pillars, the impact energy received by the pillars is relatively large, the pillars are easily damaged and...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when being hit by an out-of-control vehicle, most of the impact energy applied to the railing is directly transmitted to the pillars, and the impact energy received by the pillars is relatively large, and the pillars are easily damaged and deformed, and the pillars are damaged. The support force of the rear cross bar is weakened, so that the overall protection ability of the anti-collision structure to the vehicle is reduced
