Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] A road guardrail is composed of a plurality of columns 1, referring to figure 1 , the lower end of the column 1 is arranged in a square shape and the lower end is larger than the upper end, which can increase the contact area between the column 1 and the bottom surface and improve the stability of the column 1 . Rounded corners 8 are provided at the lower ends of the column 1 near both sides of the driveway, so that the column 1 can be toppled along the rounded corners 8 . In order to improve the connection strength between a plurality of columns 1, a plurality of ropes 2 are provided at the upper end of the columns 1 (the position of the rope 2 refers to image 3 ) through the rope-passing hole 5, in this embodiment, there are three rope-passing holes 5, which are respectively set at the two sides and the top position close to the driveway, a...

Abstract

The invention discloses a road guardrail which comprises a plurality of stand columns connected through a plurality of ropes. The road guardrail is characterized in that the ropes are connected through automatic winders; a plurality of connecting pieces used for being connected with the ground are arranged at the lower ends of the stand columns, the arrangement direction of the connecting pieces is perpendicular to lanes, and the length of the connecting pieces close to the lanes is smaller than the length of the connecting pieces at the middle position; anti-skid buffer pieces are arranged on the two sides, close to the corresponding lanes, of each stand column; the extensible ropes play a role in reducing the probability and the distance of vehicles flushing into another lanes; the three ropes penetrate through rope passing holes correspondingly to play a role in guiding of toppling of the stand columns; the arrangement of the connecting pieces further plays a role in guiding of toppling of the stand columns; the friction between the stand columns and the ground is increased through the arrangement of elastic protrusions, the sliding distance of the stand columns is reduced, and meanwhile, the effects of buffering vehicles and preventing slight scratch are achieved; liquid storage cavities can achieve a temporary fire extinguishing effect; and the number and the spacing of the stand columns can be selected according to needs, so that the flexibility of the road guardrail is improved.

Description

technical field [0001] The invention relates to the technical field of urban construction, more specifically, it relates to a road guardrail. Background technique [0002] Guardrail is a very important road safety equipment. Its main function is to prevent abnormal vehicles from crossing the road or crossing the guardrail into the opposite lane; protecting roadside facilities, inducing out-of-control vehicles, protecting pedestrians and occupants, and avoiding secondary ACCIDENT. [0003] The Chinese invention patent with the publication number CN103510481A discloses a new type of road buffer guardrail structure, including columns, metal corrugated boards, rubber buffer strips, and road guardrails. Rubber buffer belt, when the vehicle collides with the road guardrail, the rubber buffer belt can protect the safety of the vehicle. [0004] But above-mentioned guardrail can only play the purpose of protecting self-vehicle, and when vehicle collides with guardrail, the collisi...
