Traffic facility rod-column-combined car-collision-resistant facility structure

Abstract

The invention relates to a traffic facility rod-column-combined car-collision-resistant facility structure. The structure comprises an isolated pile cluster and a flexible energy dissipation anti-collision body; the isolated pile cluster comprises a plurality of vehicle stand columns; the tops of the stand columns are connected into a whole through cross beams; the flexible energy dissipation anti-collision body comprises two C-shaped outer side flexible anti-collision bodies; and the two C-shaped anti-collision bodies are in butt joint horizontally, and are fixed to a closed structure througha mortise-tenon mode and arranged at the top of the isolation pile cluster in a sleeving mode. The impact force of cars is reduced through isolation and flexible energy dissipation, the impact forceis prevented from being directly transmitted to traffic facility rods and columns, the effect of dissipating energy and reducing the impact force are achieved, the traffic facility rods and columns are protected, and damage to the cars is reduced.

Description

technical field [0001] The invention belongs to the technical field of traffic safety protection, and in particular relates to a pole-pillar combined anti-collision facility structure for traffic facilities. Background technique [0002] With the development of my country's traffic construction, the growth rate of car ownership is significantly higher than that of highways and urban roads, which leads to the unoptimistic road traffic safety in my country, and frequent accidents of cars hitting road traffic poles. For the accident of a car colliding with a pole, on the one hand, the pole with higher strength will cause serious damage to the relatively fragile body, and even threaten the safety of passengers in the car; on the other hand, for important structural supports such as electric poles, Signs, etc., will be deformed under the impact of the vehicle, which will affect the safety of the supporting top structure. In severe cases, the top supporting structure will slip and...

Problems solved by technology

There are some problems in these protective measures, such as pasting warning signs, which only play a warning role and cannot deal with unexpected situations; enlarging the lower structure is a method to improve its own strength, but for collision vehicles, larger structural dimensions And higher structural strength undoubtedly increases the risk of collision; when installing the anti-collision barrier, it is necessary to reserve enough distance from the fortification structure, while occupying the road space, the rigid anti-collision barrier will also cause greater damage to the collision vehicle ;Paste the anti-collision strip, its own energy consumption effect is limited, it is difficult to play the role of structural energy consumption protection against vehicle impact
