Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to an anti-collision barrier guardrail for a highway. Background Art

[0002] The corrugated beam guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced ​​together and supported by columns. The guardrail consists of two corrugated steel guardrail panels and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail panels. It uses the deformation of the soil foundation, columns, and beams to absorb collision energy and force out-of-control vehicles to change direction and return to the normal driving direction to prevent vehicles from running off the road, thereby protecting vehicles and passengers and reducing losses caused by accidents. The corrugated beam guardrail is both steel and flexible, has a strong ability to absorb collision energy, has a good visual induction function, can be coordinated with the road line shape, and has a beautiful appearance.

[0003] The prior art refers to the anti-collision guardrail for highways disclosed in the announcement number CN215482591U. Through the arrangement of the blocking block and the buffer material, the cooperation between the two can drive the guardrail plate to move upward when a collision occurs, so that the impact resistance of the anti-collision guardrail can be increased, and the gap in the guardrail plate caused by the collision of the vehicle can be effectively prevented, resulting in the vehicle flying out. At the same time, the buffer material makes the device more stable and has high energy absorption efficiency, which can increase the dissipation speed of the impact force, improve the safety performance, and reduce the probability of vehicle damage and personal injury.

[0004] However, the existing technology directly fixes the guardrail plate to the column, so that when the guardrail plate is hit by a vehicle, the column is also subjected to the impact force, and the buffering effect of the vehicle achieved by the buffer material in the barrier block is poor; for this reason, we have designed a highway anti-collision barrier guardrail. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the prior art, the guardrail plate is directly fixedly connected to the column, so that when the guardrail plate is hit by a vehicle, the column is also subjected to the impact force, and the buffering effect on the vehicle is poor achieved by the buffer material in the barrier block, and a highway anti-collision barrier guardrail is proposed.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model is installed between the column and the corrugated guardrail plate through a hollow hexagonal prism-shaped connector. When the guardrail plate is hit by an accident vehicle, due to the structural characteristics of the connector, the connector absorbs the impact force of the accident vehicle and deforms, which plays a buffering effect to protect the vehicle, while preventing the column from being directly hit and leaving the ground, thereby preventing the accident vehicle from rushing out of the guardrail.
