[0002] Anti-glare panels are a type of traffic safety product manufactured to solve the glare of oncoming headlights and installed on the central median of highways. Most of them are installed on the guardrails of the central median of highways or in the middle of the guardrails. Some are also installed on the movable guardrails of the central opening. They are divided into steel anti-glare panels, plastic anti-glare panels, and fiberglass anti-glare panels based on the material. In terms of appearance, the common ones are ordinary straight panels, reverse S-shaped panels, imitation relief anti-glare panels, and highway landscape anti-glare panels.
[0003] There are three methods for structural treatment of the anti-glare panel and the central dividing strip guardrail: first, the anti-glare panel is combined with the concrete guardrail, which relies on the embedded parts on the top of the concrete, generally by welding; second, the anti-glare panel is combined with the corrugated beam guardrail, and a cross beam (channel steel) can be added to the guardrail column, and the anti-glare panel is fixed on the channel steel, or the anti-glare panel can be fixed on the combined guardrail column; third, the anti-glare panel is embedded in the central dividing strip by erecting a separate column.
[0004] Under normal circumstances, the anti-glare panels on newly built highways are relatively intact, and the missing or damaged anti-glare panels can often be repaired in time, and the anti-glare function will not be lost. However, on highways where the guardrails have been modified, the anti-glare panels may not be installed. For example, on highways where the corrugated beam guardrails have been changed to concrete guardrails, manholes appear on the highway, resulting in discontinuity between the concrete guardrails, making it impossible to install the anti-glare panels that should have been installed, thus affecting the driving of vehicles on the highway.
