[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge and beautifying the bridge structure. There are many ways to classify bridge guardrails. In addition to classification by installation location, they can also be classified by structural features, anti-collision performance, etc.

[0003] The utility model patent with publication number CN 217629416 U in the prior art proposes a bridge guardrail that is easy to assemble, wherein the crossbars are detachably arranged on the connecting columns, and the limit pieces on the connecting columns fix the crossbars to reduce the situation where the crossbars are separated from the connecting columns to generate safety hazards. The crossbars can be connected between two connected connecting columns and supported by the supporting pieces, and both assembly and disassembly are convenient;

[0004] However, its installation and disassembly structure basically adopts multiple sets of bolts to fix and connect. The disassembly and assembly of the vertical frames on both sides need to be completed through flanges and bolts, which not only wastes time but also requires more tools to cooperate, and the construction efficiency is low. At the same time, its cross bar does not have the ability to adjust the length. When facing different vertical frame spacing settings, it is necessary to customize exclusive cross bars to match them, which greatly increases the construction cost and subsequent maintenance cost. Therefore, we need to upgrade and transform on the basis of existing technologies to overcome its existing problems and shortcomings. Summary of the invention

[0005] The purpose of the utility model is to provide a bridge guardrail that is easy to assemble, so as to solve the problems raised in the above-mentioned background technology.
