Embodiment Construction

[0024] 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.

[0025] 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 bracket 20 arranged on each pillar 10 and a horizontal bar 30 arranged on the brackets. In this figure, only one pillar and the bracket arranged on the pillar are shown.

[0026] The pillars 10 are arranged along the extending direction of the road. Each pillar 10 is a cylindrical structure, specifically carbon steel pi...

Abstract

The invention provides a road protective fence. The road protective fence comprises a support pillar, a horizontal fence, and a bracket arranged on the support pillar; the bracket includes an arcuate portion arranged on the support pillar, two extending portions formed by extending from both sides of the arcuate portion towards the inner side of a road respectively, and a fixing portion formed by the bending and extending of the distal end of each of the extending portions; a through hole is arranged on the support pillar; the arcuate portion, corresponding to the position of the through hole of the support pillar, is provided with a card hole; the extension portion is provided with a guide hole communicated with the card hole; the road protective fence further comprises the card hole arranged at the bracket in a penetrating mode and a screw arranged in the through hole of the support pillar in a penetrating mode; the guide hole is a bar-shaped hole extending along the extending direction of the extension portions; when the horizontal fence is subjected to the impact force towards the outer side of the road, the screw can be divorced from the card arrangement of the card hole to slide along the guide hole, and the horizontal fence is fixed to the fixing portion. The road protective fence can absorb the energy generated when vehicles are hit, thereby reducing the injury degree of people in the vehicles.

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...
