Description

Safety barrier structure for highway bridge

Technical Field

The utility model relates to a public road bridge roof beam technical field specifically is a safety barrier structure for public road bridge roof beam.

Background

The highway bridge guardrail is a guardrail arranged on a highway bridge, and when the guardrail is arranged on two sides of a road bridge, the purpose is to prevent an out-of-control vehicle from crossing the road bridge, and meanwhile, the guardrail can also separate a motor vehicle lane and a non-motor vehicle lane, and when the guardrail is arranged in the middle of the road bridge, the guardrail can separate lanes in two directions to prevent the vehicle from occupying opposite lanes to cause safety accidents.

Current highway is guardrail factor of safety for bridge is not high, and when the vehicle guardrail that is out of control bumps, two kinds of situations can appear generally, one kind is the guardrail fracture, the condition that the vehicle rushes out, another kind is direct rigid collision, lead to the vehicle impaired seriously, driver and passenger bear huge impact, but the result that these two kinds of situations lead to is all more serious, even at present under the condition that there is the guardrail to exist, still exist the pedestrian and cross the road, the condition of crossing the guardrail, also can increase the probability that the traffic accident takes place.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safety barrier structure for public road bridge roof beam to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a safety barrier structure for public road bridge roof beam, includes a plurality of buffering stake, the buffering stake includes the base, it is provided with two pillars, two to slide on the base the spring that a plurality of arrays of fixedly connected with distribute between the pillar, two one side that the spring was kept away from to the pillar is fixed mounting respectively has the reflector panel that a plurality of arrays distribute, two the connecting block that a plurality of arrays distribute is welded respectively to both sides in addition on the pillar, two adjacent fixed mounting respectively has a railing between two correspond the connecting block on the buffering stake, and wherein a set of top that is located fixed mounting has a plurality of diagonal rods that crisscross the setting on the railing.

Furthermore, a T-shaped sliding groove is formed in the base, a T-shaped sliding block is arranged at the bottom of the support column, and the T-shaped sliding block is arranged in the T-shaped sliding groove in a sliding mode.

Furthermore, the number of the springs on each buffer pile is not less than three, and the springs can generate elastic force when the railings or the pillars are impacted, so that the impact buffering effect is achieved.

Further, be located on every pillar the quantity of reflector panel is no less than one, and the reflector panel can be at night or reflection vehicle light when light is dim, plays the warning effect.

Further, the distance between the upper part and the lower part of the railings on the same side is 100 mm and 200mm, so that pedestrians can be prevented from passing through the guardrails from the gaps between the railings.

Furthermore, the inclination angle of the inclined rods is 30-50 degrees, and the inclined rods are arranged in a staggered and inclined mode, so that pedestrians can be prevented from crossing the road and crossing the guardrail.

Compared with the prior art, the beneficial effects of the utility model are that: this safety barrier structure for highway bridge, through the base, the pillar, cooperation between the spring, can be when the vehicle is out of control to hit railing or pillar, the spring produces reverse elasticity in compression process to the striking dynamics of buffering vehicle can protect driver and passenger's safety to a certain extent, and the down tube that sets up the slope in a staggered way moreover can prevent the pedestrian and cross the road, climbs the guardrail, thereby reduces because of the pedestrian crosses the road and causes the probability of accident.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a safety guardrail structure for highway bridges comprises a plurality of buffer piles, wherein each buffer pile comprises a base 1, the base 1 is fixed on a roadbed of a highway bridge, two pillars 2 are arranged on the base 1 in a sliding mode, T-shaped sliding grooves 101 are formed in the base 1, T-shaped sliding blocks 201 are arranged at the bottoms of the pillars 2, the T-shaped sliding blocks 201 are arranged in the T-shaped sliding grooves 101 in a sliding mode, eight springs 4 distributed in an array mode are fixedly connected between the two pillars 2, the springs 4 can generate elastic force when a railing 5 or the pillar 2 is impacted to play a role in buffering impact, four reflecting plates 3 distributed in an array mode are fixedly arranged on one sides, far away from the springs 4, of the two pillars 2 respectively, the reflecting plates 3 can reflect vehicle light at night or when the light is dim, a warning effect is achieved, four connecting blocks 202 distributed in an array mode are welded on the other two sides of the two pillars 2 respectively, the provision of the connecting block 202 can facilitate the mounting of the balustrade 5.

The guardrail comprises two adjacent buffer piles, wherein a guardrail 5 is fixedly installed between two corresponding connecting blocks 202 on the two adjacent buffer piles respectively, the distance between the upper portion and the lower portion of the guardrail 5 on the same side is 100-200mm, so that pedestrians can be prevented from passing through the guardrail from gaps between the railings 5, a plurality of inclined rods 6 which are arranged in a staggered mode are fixedly installed on the railings 5 on the top of the one group of the guardrail 5, the inclined angles of the inclined rods 6 are 30-50 degrees, and the inclined rods 6 are arranged in a staggered mode to prevent the pedestrians from crossing the road and crossing the guardrail.

The working principle is as follows: when a traffic accident occurs on a highway bridge, when a vehicle is out of control and collides with the guardrail 5 or the support post 2 of the safety guardrail structure for the highway bridge, which is arranged in the middle of a road or on two sides of the road, the support post 2 can compress the spring 4 by the impact force, and the spring 4 generates reverse elasticity in the compression process, so that the impact force of the vehicle can be buffered, and the safety of a driver and passengers can be protected to a certain extent. The staggered and inclined arrangement of the inclined rods 6 can prevent pedestrians from crossing the road and crossing the guardrail, so that the probability of accidents caused by the fact that the pedestrians cross the road is reduced.
