Anti-collision protection fence plate for highway

Abstract

The invention provides a highway anti-collision protection plate. As the rigidity is too high and the elasticity is not enough, the prior highway anti-collision protection plate has the problems that the capacity of alleviating impact is small and the accident damage to vehicles and human bodies cannot be effectively reduced. Aiming to solve the above problems, the invention provides the technical proposal that the highway anti-collision protection plate is composed of a hollow plate made of plastic and a plastic surface layer for coating the hollow plate, the hollow plate comprises an inner layer sleeving body which is externally sleeved with an outer layer sleeving body and is internally provided with a stiffener, and a stiffener is also arranged in the clearance between the outer layer sleeving body and the inner layer sleeving body. The highway anti-collision protection plate has the advantages that the strength required by a steel-made protection plate is satisfied, the capacity of alleviating the impact is strong, surface cracking cannot happen after the impact, and an intermediate skeleton structure is damaged after absorbing the impact, thereby minimizing the damage to the vehicles and the human bodies.

Description

Highway anti-collision guardrail technical field The invention relates to the field of road safety protection, in particular to an expressway anti-collision guardrail. Background technique The main function of the highway anti-collision guardrail is to control the driver's driving route, ensure the safe driving of the vehicle, reduce the occurrence of accidents, and reduce the loss of the accident vehicle and the casualty coefficient of the people in the vehicle when the accident occurs. Most of the current highway crash barriers include crash barriers and columns. The crash barriers are made of solid metal plates such as steel. Such crash guards have too high hardness and insufficient elasticity, so that the ability to alleviate impacts is small and cannot be effective. Reduce the damage to vehicles and human body caused by accidents.
