Embodiment Construction

[0025] 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.

[0026] Such as figure 1 and figure 2 As shown, the road protection fence includes a plurality of pillars 10 arranged side by side and spaced apart, a bracket 20 provided on each pillar 10, and a horizontal rail 30 provided on the bracket. In this figure, only one pillar and the support provided on the pillar are shown.

[0027] The pillars 10 are arranged along the extending direction of the road. Each pillar 10 has a cylindrical structu...

Abstract

The invention provides a road protective fence. The road protective fence comprises a support pillar, a horizontal fence, a bracket arranged on the support pillar, and a buffer member arranged on the horizontal fence; 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 fence. 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 pr...
