Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as figure 1 and figure 2 As shown, the highway guardrail includes a plurality of pillars 10 arranged side by side at intervals, a guardrail plate 20 arranged on the pillar 10, and a guard end plate 30 located at the end of the guardrail plate 20. Only one pillar is shown in the figure.

[0024] The guardrail 20 is fixed to the pillar 10 by a connecting piece 50. In this embodiment, each pillar 10 is cylindrical, and its bottom...

Abstract

The invention proposes a road protection fence, and the protection fence comprises a plurality of supporting columns arranged at intervals, a fence plate disposed on the supporting columns, and protection end plates located at end parts of the fence plate. The fence plate and the protection end plates are respectively made of elastic metal materials. The protection fence plate is corrugated in a manner that concave parts and convex parts are alternately arranged in a vertical direction. Each protection end plate comprises a plane part which is fixed at an end part of the fence plate, and a curled part which is bent from an end part, far from the fence plate, of the plane part. The curled part is curled from an end part, far from an end part of the fence plate, of the plane part to a back side of the fence plate in a reciprocating manner, thereby forming a plurality of cylindrical layers. The supporting columns respectively comprise a metal tube core and a wood cylinder sleeving the metal tube core. The protection fence surrounds a pointed corner part of an end part of the fence plate through the protection end plates, thereby forming an elastic body with the fence plate. The protection fence can absorb the energy generated by the impact of a vehicle, and alleviates the damage of persons in the vehicle.

Description

Technical field [0001] The invention relates to a traffic railing, in particular to a highway guard rail. Background technique [0002] At present, traffic accidents involving anti-collision guardrails often occur on expressways or traffic roads. The speed of the vehicles involved is too fast. The existing rigid guardrails composed of cement piers or fixed steel pipes cannot effectively absorb the collision kinetic energy, causing the car to roll over and make the driver and passenger The personnel were seriously injured. If the rigid guardrail can effectively absorb the collision kinetic energy and decelerate, the injuries to the traffic accident drivers and passengers of the driving vehicle hitting the guardrail will be greatly reduced. The existing rigid guardrail only relies on friction to absorb the kinetic energy of the collision during the collision, and the damping time is too short. Due to the poor energy absorption and deceleration effect, it does not provide due prote...
