A kind of semi-rigid bridge anti-collision guardrail

Abstract

The invention discloses a semi-rigid bridge anti-collision guardrail, which comprises a plurality of guardrail steel skeleton structures connected in sequence, and the guardrail steel skeleton structures connected in turn form a continuous arch structure; the guardrail steel skeleton structure includes steel longitudinal beams and arched steel pipes and two steel columns, the two ends of the steel longitudinal beam are respectively fixedly connected with the two steel columns, and the two ends of the arched steel pipe are respectively fixedly connected with the two steel columns; anchor between the steel columns at the two ends of the linked arch structure There are cables; among the steel longitudinal beams, arched steel pipes and cables, along the width direction of the bridge deck, the steel longitudinal beams are set close to the side of the bridge deck; the arched steel pipes are set at a distance from the bridge deck relative to the steel longitudinal beams The position of the arched steel pipe is towards the side of the bridge deck, and the steel pipe column for force transmission is connected between the arched steel pipe and the steel longitudinal beam; the cable is set at a position farther away from the bridge deck than the arched steel pipe . The problem of insufficient anti-collision performance of the anti-collision barrier in the prior art is solved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a semi-rigid bridge anti-collision guardrail. Background technique [0002] Bridge guardrail refers to the guardrail installed on the bridge. Its purpose is to prevent out-of-control vehicles from going out of the bridge, and has the functions of preventing vehicles from breaking through, passing under, and overturning the bridge and beautifying the bridge building. Bridge guardrails are an important part of bridges. Bridge guardrails can not only increase the beauty and brilliance of bridges, but also play a good role in warning, blocking and preventing traffic accidents. According to the anti-collision performance, bridge guardrails can be divided into flexible bridge guardrails. 1. Semi-rigid bridge guardrail and rigid bridge guardrail. The purpose of this product is to prevent out-of-control vehicles from getting out of the bridge. The main form of the flexible bridge guar...
