Description

Bridge guardrail

Technical Field

The utility model relates to a bridge safety technical field especially relates to a bridge guardrail.

Background

Along with the continuous development of infrastructure facilities in China, the requirements of highway bridges are more and more, bridge guardrails are arranged on two sides of the bridge, vehicles can not break through, wear down and cross the bridge in order to prevent out-of-control vehicles from crossing the bridge, and the bridge guardrails which are reasonably designed can beautify the bridge facilities while playing a role in protection. The anti-collision grade can be determined according to factors such as actual conditions of a highway on site, and then the factors such as economy, construction maintenance and the like are comprehensively considered to select and arrange the configuration of the guardrail according to the self structural condition of the guardrail. Traditional bridge railing is not good to the protection effect that the bridge vehicle was hit to the mistake, does not have the resiliency, all can produce serious consequence to bridge and car after the accident, and it is also inconvenient to maintain, has not only increased the maintenance cost of guardrail and frame utensil, has still wasted not few manpower and materials.

Aiming at the problems, how to design an anti-collision guardrail facility with a buffering effect becomes a problem to be solved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a bridge railing of simple structure, security performance are higher, and have multiple buffering effect.

In order to solve the technical problem, the utility model provides a bridge guardrail, which comprises a base fixedly connected with a bridge floor; the main guardrail comprises a left upright post, a right upright post, an upper transverse post and a lower transverse post, the upright posts are vertically arranged on the base, the transverse posts and the upright posts are fixed by welding, and the bottoms of the transverse posts below the transverse posts are provided with a plurality of grooves; the auxiliary guardrail comprises a plurality of longitudinal supports and a plurality of transverse supports, wherein the transverse supports are arranged between the two stand columns at equal intervals, the bottom ends of the longitudinal supports are fixed in corresponding grooves in the bottoms of the transverse supports respectively and are in interference fit with the grooves, and the bottom ends of the longitudinal supports are provided with rubber rings between the grooves.

Similarly, in the connection of the cross arm and the upright column, a rubber ring with a buffering effect is arbitrarily arranged in the groove, and the rubber ring not only can form a buffering effect similar to a spring between the main guardrail and the auxiliary guardrail, but also can increase the friction force between the main guardrail and the auxiliary guardrail.

The adjacent crossing point department of indulging between vaulting and the stull sets up columniform rubber post, and the rubber post will indulge the vaulting through the bolt and link together with the stull to but make supplementary guardrail buffering set up arrange a plurality of nodes between main guardrail, increase buffering effect.

Stand and stull set up in the outside, and the bottom of stand is passed the base and is fixed continuous with the bridge floor, increases bridge railing's fastness, and the both ends of stull link to each other with the stand, indulge to prop and pass through the stull on the groove with it fixed continuous, the stull with indulge to prop and be set up in the inboard together. When the accident that the vehicle collides with the bridge guardrail occurs, the vehicle firstly contacts the guardrail formed by the cross braces and the longitudinal braces in a staggered manner, and the rubber columns between the cross braces and the longitudinal braces buffer the guardrail so as to reduce the damage of the vehicle to the main guardrail; when the speed of the vehicle is higher, the kinetic energy of the vehicle can further impact the inner side longitudinal support; the joint of the main guardrail and the auxiliary guardrail is separated by a rubber ring. When the car strikes the inside and outside auxiliary guardrail, the rubber circle can also allow the stull and indulge the shoring in horizontal and fore-and-aft moving when playing the cushioning effect, further alleviates the impact energy that the car striking brought to can reduce the kinetic energy that the car striking produced by a wide margin in the accident, reduce the harm nature of accident.

Further, the arc setting of incurving is carried out on the top of indulging the brace, can avoid the pedestrian to scramble, stretch out the head and visit etc. and cause the crash accident.

The technical effects of the utility model are that: the utility model discloses a bridge guardrail for prior art, main guardrail in adopting, interior guardrail, outer main guardrail, the cooperation of outer guardrail of assisting, when receiving the striking, carry out elastic buffer by rubber post and rubber circle to assisting the guardrail, the stand links to each other with the bridge floor is fixed, and the spreader passes through the welding with the stand and links to each other, increases bridge guardrail's fastness, has reduced the rigidity collision of vehicle, reduces the harmfulness of accident.
