Description

TECHNICAL FIELD

[0001] The present application relates to the field of guardrails, and in particular to an assembled wind-resistant and corrosion-resistant guardrail. BACKGROUND

[0002] With the development of society and the acceleration of urbanization, various infrastructure construction is increasing, especially in the fields of transportation, industry, and public facilities. Guardrails, as important safety protection facilities, play an irreplaceable role in ensuring the safety of pedestrians and vehicles and maintaining public order. Traditional guardrails mostly use on-site welding or bolt fixing construction methods, which have problems such as complex installation, long construction period, and high maintenance cost. In recent years, assembled guardrails have gradually gained market favor due to their convenient installation, reusability, and simple maintenance.

[0003] However, existing assembled guardrails still face many challenges in certain specific environments. In particular, in areas with strong winds, such as coastal cities, the wind resistance of guardrails is particularly important. In strong wind weather, the insufficient wind resistance of guardrails not only affects their own stability and safety, but also can potentially threaten the surrounding environment and facilities, so there is room for improvement.

[0008] By adopting the above technical scheme, when the connecting bolt is tightened, on the one hand, the fastening pad can protect the fixing sheet from being crushed by the connecting bolt; on the other hand, the fastening pad has elasticity, and when the connecting bolt is tightened, the fastening pad can abut against the connecting bolt, thereby avoiding loosening of the connecting bolt.

[0009] Optionally, the second fixing column is connected with a guide block at one end.

[0010] By adopting the above technical scheme, the guide block can give a guide to the second fixing column, so that the second fixing column can be quickly inserted into the second fixing hole or the third fixing hole.

[0011] Optionally, the cross bar is provided with a mounting slot for inserting the protective plate, an inner side wall of the mounting slot is provided with a sliding slot, the sliding slot is slidably connected with a mounting column, a limit spring is connected between the mounting column and a bottom wall of the sliding slot, one end of the mounting column extending out of the mounting slot is connected with a mounting strip, the mounting strip is connected with a first clamping block, an inner side wall of the mounting slot away from the mounting strip is connected with a second clamping block, both ends of the protective plate are provided with a first clamping slot for clamping the first clamping block and a second clamping slot for clamping the second clamping block.

[0012] By adopting the above technical scheme, when the protective plate is mounted, the mounting strip is first pushed, so that the mounting column is pressed into the sliding slot, then the protective plate is inserted into the mounting slot, the protective plate is moved, so that the second clamping block is clamped into the second clamping slot, then the mounting strip is loosened, so that the first clamping block on the mounting strip is clamped into the first clamping slot, thereby fixing the protective plate in the mounting slot.

[0013] Optionally, the protective plate is uniformly provided with a plurality of through holes.

[0014] By adopting the above technical scheme, the through holes not only can reduce the direct impact of the wind on the guardrail, but also can maintain a certain permeability and reduce wind resistance.

[0015] Optionally, the outer surfaces of the stand, the cross bar and the protective plate are coated with an anti-rust layer.

[0016] By adopting the above technical scheme, the anti-rust layer can improve the anti-rust performance of the stand, the cross bar and the protective plate, thereby avoiding rust as much as possible.
