Description

Highway guardrail device

Technical field

The invention relates to a guardrail device for highways, which is mainly suitable for split protection of highway lanes. Background technique

In the prior art, the segmentation protection of the highway lane is realized by the connection of the guardrail and the column; because the length of the fence is long, the small column needs to be supported and fixed in the middle; meanwhile, because the length of the fence is impossible Infinitely long, the guardrails need to be docked with each other, and the butt joints need to be connected and fixed through the middle large columns; at the same time, the two ends of the guardrails need to be connected and fixed through the end large columns. For this reason, the design of the small column, the middle large column and the end large column structure is related to the use effect and strength of the entire guardrail device.

Chinese Patent No. 92213037X discloses a utility model patent entitled "Road W Wave Crushing Guardrail", which is composed of W-wave anti-shock guardrail plates with different cross-section dimensions at both ends, which are lapped and fixed on the road surface by screws. on. Since the guardrail of the invention patent is directly fixed to the column with screws, the impact resistance is not good, and the safety of use is not high; at the same time, the plate body is not made of PVC resin, so it is easy to oxidize and rust, collide It is easy to damage the car.

Chinese Patent No. 200820157983X discloses a utility model patent entitled "Highway Anti-collision Guardrail", which uses a U-shaped spring to connect the corrugated plate and the column. When the vehicle hits the corrugated plate, the U-shaped reed has a good elastic impact force. , reducing the damage of the vehicle. Although this structure is better than the structure in which the guardrail plate is directly fixed to the column by screws, in actual use, the structure is only applicable to the steel guardrail and cannot be used for the PVC guardrail.
