Description

Novel corrugated beam steel guardrail inserted into vehicle for preventing collision

Technical Field

The utility model belongs to public transport safety field relates to in road traffic, when the high-speed striking of sedan-chair that traveles on the road was located the wave form beam steel guardrail board of road both sides, this novel wave form beam steel guardrail can prevent in the wave form beam board inserts the car, avoids causing the emergence of aggravating the casualties incident.

Background

With the deep advance of 'life safety protection engineering', the treatment of the potential safety hazard of the road is effectively treated, the level of the road traffic safety protection is obviously improved, and protective guards, shunt side protective guards and central isolation protective guards are arranged on the common road or the expressway, particularly on the heavy point road sections such as sharp curves, steep slopes, waterside cliffs and the like, so that the vehicles running at high speed are protected, the vehicles are prevented from rushing out of the road or colliding into opposite lanes when accidents occur or the vehicles leave the road, and the accident loss and the casualties are reduced. Because the corrugated beam steel guardrail has good corrosion resistance and impact energy absorption, most of the current highway guardrails on roads adopt the corrugated beam steel guardrail. However, in reality, when a small car obliquely impacts a guardrail, particularly a guardrail end, the guardrail end is not enough in impact resistance, the guardrail end is flattened or rolled up or even falls off, the protection effect is lost, the corrugated beam plate directly penetrates into the car, and casualties of drivers and passengers on the car are caused. According to measurement, the installation height of the corrugated beam steel guardrail is generally between 90cm and 110cm from the asphalt pavement, the height of the corrugated beam steel guardrail plate is about 30cm, and the height is just basically consistent with the height of a fender of a small car head engine cover. Meanwhile, for the structure of the head of the small car, parts with anti-collision and energy absorption, such as a bumper, an engine, a gearbox and the like, are arranged below a fender of a car engine cover, when the car obliquely collides with the corrugated beam steel guardrail at high speed or directly collides the end head of the corrugated beam steel guardrail, the corrugated beam plate of the corrugated beam steel guardrail can penetrate through window glass into the car at an oblique upward angle due to large kinetic energy of the car, the anti-collision and energy absorption parts such as an anti-collision beam column of the small car basically have no protective effect, once the corrugated beam plate penetrates into the car, the corrugated beam plate becomes a sharp knife which is important for people, the consequence is very serious, the fatality rate of people in the car is very high, the dead people all cause severe damage of the brain and the head because of the blunt objects impacting the brain, according to the statistics of the public security traffic police department in Jiangxi province, only on the highway, in the traffic accident that the central or the corrugated beam steel guardrail is isolated in the near 10 years, the waveform beam plate is inserted into the vehicle, so that the road traffic accident causing casualties is not less than 10 every year, the number of dead people exceeds 10, the cumulative number of dead people caused by the collision of guardrails in the whole province exceeds 100, and the waveform beam plate with high fatality rate is often called as 'life-taking guardrail plate'! Therefore, the novel corrugated beam steel guardrail which can increase protection and is convenient to construct can prevent corrugated beam plates from being directly inserted into a vehicle when the vehicle runs out of control at a high speed or an accident happens to collide the corrugated beam steel guardrail, and avoid casualties of drivers and passengers on the vehicle, and is very necessary.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: when the small car running at high speed is out of control or an accident occurs to impact the corrugated beam steel guardrail, the corrugated beam plate is easily inserted into the car to cause casualties of drivers and passengers on the car, the novel corrugated beam steel guardrail for preventing the impact on the car is provided, the safety of road driving is improved, and the damage consequence of the traffic accident is reduced.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a prevention receives novel wave form beam steel guardrail that striking inserted in car, includes stand, wave form beam slab semiellipse shape turn-up end, connecting bolt, prevents the piece that hinders. According to the national standard 'waveform beam steel guard rail' (GBT 31439.1-2015), the waveform beam steel guard rail consists of a waveform beam plate, an upright post, an end head, a splicing bolt, a connecting bolt, a stop block, a bracket, a diaphragm beam and other components, and according to the principle that the reconstruction is convenient and the structure meets the national standard requirements, one end of the waveform beam plate is bent into a semi-elliptical shape along the vertical direction to form a semi-elliptical curled end head, and then the semi-elliptical curled waveform beam plate is fixed on the upright post through the connecting bolt; the novel corrugated beam steel guardrail for preventing the novel corrugated beam steel guardrail from being inserted into a vehicle due to impact is characterized in that one end of the existing corrugated beam plate is bent into a semi-elliptical shape along the vertical direction in the production process to form a semi-elliptical curled end; in the installation process, one end of the semi-elliptical shape is fixed on the anti-blocking block through a connecting bolt on one side of the upright column close to the driving road surface, the anti-blocking block is fixed on the upright column through a connecting bolt, the semi-elliptical curled-edge corrugated beam plate is fixed on the upright column through a connecting bolt on one side of the upright column far away from the driving road surface, and the structure and the installation of other parts are not different from the requirements in the national standard corrugated beam steel guardrail (GBT 31439.1-2015).

The utility model has the advantages that: the novel corrugated beam steel guardrail for preventing the corrugated beam steel guardrail from being inserted into a vehicle under the impact is characterized in that one end of a corrugated beam plate is bent into a semi-elliptical shape along the vertical direction to form a semi-elliptical curled end, the corrugated beam plate is fixed on a stand column by using connecting bolts at two sides of the stand column respectively, so that the section of the corrugated beam plate facing to the driving direction is the semi-elliptical beam plate instead of a sharp knife which is a vital role when the vehicle is impacted at high speed, firstly, the contact area of the corrugated beam plate and the vehicle is increased, secondly, the two sides of the stand column are fixed by the connecting bolts, the combination degree of the corrugated beam plate and the stand column is increased, the risk that the corrugated beam plate falls off from the stand column and is inserted into the vehicle is reduced, the stand column is deeply buried on the ground and has larger pulling resistance, the stand column which is impacted and inclined can pull the corrugated beam plate to the bottom of the vehicle under the impact can prevent the corrugated beam plate of the corrugated beam steel guardrail from passing through a vehicle window glass at an inclined upward angle to enter the vehicle, the purpose of reducing casualties after accidents is achieved.
