Anti-collision guardrail assembly structure based on hot-rolled steel

Abstract

The anti-collision guardrail assembly structure based on the hot-rolled steel comprises a guardrail stand column, a plurality of butt joint pipes are fixedly connected to the middle of the guardrail stand column, and horizontal handrail assemblies are installed on the inner walls of the butt joint pipes; the horizontal handrail assembly comprises a blocking plate, a bearing plate is arranged on one side of the blocking plate, a cavity is formed in the middle of the blocking plate, and a reset push plate is slidably connected to the inner wall of the cavity. The butt joint pipes are arranged on the guardrail stand columns to install the horizontal guardrail assembly, the connecting stability of the assembling pipes and the butt joint pipes is improved through limiting butt joint of the limiting elastic pieces and the assembling grooves, meanwhile, the limiting elastic pieces are arranged in a bent mode, and therefore when the blocking plates are impacted by external force and move, the blocking plates can be prevented from being damaged through bending deformation of the limiting elastic pieces. And impact is buffered and absorbed, and the overall anti-collision capacity of the guardrail is effectively improved.

Description

technical field [0001] The invention relates to the related technical field of guardrails, in particular to an assembly structure of anti-collision guardrails based on hot-rolled steel. Background technique [0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas and public places. [0003] When the guardrail is produced, most of the individual parts are produced separately, and then assembled when used. Such as figure 1 In the shown guardrail structure, when it is assembled, the first leg and the second leg are welded and fixed on the column. The guardrail obtained by this assembly method is only a simple rigid connection, and its overall impact on the vehicle The cushioning ability is poor, and it is easy to be twisted and deformed when it is impacted, and the service life is short. Contents of the invention [0004] The object of the present invention is to provide ...
