Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] Such as figure 1 and figure 2 As shown, the road guardrail includes a plurality of pillars 10 arranged side by side at intervals, a guardrail 20 on the pillars 10 and a protective end plate 30 at the end of the guardrail 20 , only one pillar is shown in the figure.
[0022] The guardrail 20 is fixed on the pillar 10 through a connecting piece 50 . In this embodiment, each pillar 10 is a square column, and its bottom end is buried under the ground suc...

The invention provides a road guard railing which comprises a plurality of supporting columns arranged side by side at intervals, a guard railing plate arranged on the supporting columns and a protection end plate located at the end of the guard railing plate. The guard railing plate and the protection end plate are both made from elastic metal, the guard railing plate is corrugated, concave portions and convex portions are alternately arranged in the vertical direction, the protection end plate comprises a plane part fixed to the end of the guard railing plate and a bent part formed by bending the end, away from the guard railing plate, of the plane art, the bent part is in a vortex shape formed by bending the end, away from the guard railing plate, of the plane part towards the back side of the guard railing plate. According to the road guarding railing, the sharp corners at the end of the guard railing plate are wrapped by the protection end plate, an elastomer is formed by the protection end plate and the guard railing plate, energy generated during vehicle collisions can be absorbed, and the injury degree of personnel in a vehicle can be reduced.
Description
technical field [0001] The invention relates to a traffic railing, in particular to a road protection railing. Background technique [0002] At present, traffic accidents of anti-collision barriers often occur on expressways or traffic roads. The speed of the vehicle involved in the accident is too fast. Personnel were seriously injured. If the rigid guardrail can effectively absorb the collision kinetic energy and decelerate, the injuries of the drivers and passengers in traffic accidents caused by the running vehicle hitting the guardrail will be greatly reduced. The existing rigid guardrail only relies on frictional force to absorb the kinetic energy of the collision during the collision process. The damping time is too short. Because of the poor energy absorption and deceleration effect, the safety of the car and the occupants is not adequately protected. There is room for improvement. Contents of the invention [0003] The invention proposes a road guardrail, which...
