Description

High-stability anti-blocking block

Technical Field

The utility model relates to the field of anti-blocking blocks, in particular to a high-stability anti-blocking block.

Background

The anti-blocking block refers to an anti-blocking block of the road side corrugated beam guardrail and is a bearing component between the corrugated beam and the upright post. The road section is suitable for road sections in which traffic flow is complex in types and there is concern that collision vehicles possibly mix with the guardrail posts, or road sections in which the movement track of the collision vehicles is adversely affected by the curb. The guardrail can be deformed gradually after collision, is favorable for energy absorption and reduces the casualties of passengers, and meanwhile, the anti-blocking block is fixed between the upright post and the wave beam and can distribute collision force to more span structures after participating in the integral action of the guardrail, so that the integral strength of the guardrail is increased.

The application number is CN 202122432151.2 in the current patent, discloses a novel anticollision barrier energy-absorbing anti-blocking piece, has fine buffering resilience's effect when meetting external impact to the horizontal pole through the side elastic support bow that the symmetry set up. However, when a high-speed vehicle collides with the guardrail plate, the impact force generated cannot be effectively absorbed by adopting a single elastic supporting bow structure, and the elastic supporting bow is easy to damage to cause failure in rebound, so that the anti-blocking effect is affected.

The foregoing is not necessarily a prior art, and falls within the technical scope of the inventors.
