A new type of safety guardrail structure for highway bridges

Abstract

The invention belongs to the technical field of guardrails, in particular to a new type of safety guardrail structure for highway bridges, including a base, the top of the base is symmetrically fixed with risers, and four square inserts are equidistantly arranged on the side walls of the risers. holes, four connection plates are equidistantly arranged above the base, square inserts are symmetrically fixed on the side walls of the connection plates, and the square inserts slide through the corresponding square sockets respectively. The side walls of the connecting plates are all attached to the side walls of the vertical plates. The present invention cooperates with the vertical plate, the connecting plate, the square insert block, the support plate, the fixed plate, the slide plate, the cross bar, the pull plate, the first spring, the triangular block, the square clamping rod and the trapezoidal block. When the vehicle hits the protective plate, it can be replaced more conveniently and quickly. Through the telescopic sleeve, the second spring, the bracket block, the guide rod, the connecting block, the third spring and the connecting rod, when the vehicle hits the protective plate, it can play a greater role. Good shock absorption and cushioning.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a novel safety guardrail structure for highway bridges. Background technique [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. [0003] At present, the buffer performance of guardrails for highway bridges is poor, and they are prone to damage when they are hit by vehicles. Moreover, after the protective components of guardrails for highway bridges are damaged, it is difficult to replace them, resulting in low maintenance efficiency. Therefore, we propose a The novel highway bridge solves the above problems with a safety guardrail structure. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the invention provides a novel safety guardrail structure for highway bridges, which solves the problems of poor cushi...
