Description

Bridge guardrail

Technical Field

The invention relates to the technical field of bridges, in particular to a bridge guardrail.

Background

The bridge is generally a structure which is erected on rivers, lakes and seas and allows vehicles, pedestrians and the like to smoothly pass through. In order to adapt to the modern high-speed developed traffic industry, bridges are also extended to be constructed to span mountain stream, unfavorable geology or meet other traffic needs, so that the buildings are convenient to pass. The bridge generally comprises an upper structure, a lower structure, a support and an auxiliary structure, wherein the upper structure is also called a bridge span structure and is a main structure for spanning obstacles; the lower structure comprises a bridge abutment, a bridge pier and a foundation; the support is a force transmission device arranged at the supporting positions of the bridge span structure and the bridge pier or the bridge abutment; the auxiliary structures refer to bridge end butt straps, tapered revetments, diversion works and the like.

The bridge is the primary structure who stridees across the obstacle, can be provided with the guardrail in the both sides of bridge usually, prevents that pedestrian or vehicle that pass by from not protecting directly dropping and taking place danger, but current bridge guardrail lacks the security on satisfying the pleasing to the eye basis of outward appearance, and the function is too simple, when meetting the vehicle striking, and the power that the striking produced is whole to be acted on the guardrail surface, leads to the degree that vehicle and guardrail damaged all than higher, and the guard action of guardrail is little.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a bridge guardrail, which solves the problems that the bridge guardrail is lack of safety on the basis of satisfying the attractive appearance, the function is too simple, the force generated by impact is completely acted on the surface of the guardrail when the vehicle is impacted, the damage degree of the vehicle and the guardrail is higher, and the protection effect of the guardrail is not high.

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a bridge guardrail, includes the bridge base face, the outer fixed surface of bridge base face is connected with the fender pile, the afforestation groove has been seted up at the top of fender pile, the surface of fender pile has just been located the below in afforestation groove and has seted up logical groove, curved groove has all been seted up to the top and the bottom that lead to inslot surface, the internal surface in curved groove is provided with elastic mechanism, two even sliding connection has curved shape pole between the relative one side in curved shape groove, the outer fixed surface of curved shape pole is connected with anticollision institution, swing joint has buffer gear between the surface of curved shape pole and the internal surface in curved groove, the internal surface that leads to the groove just is located the even fixedly connected with bevel window in curved shape pole's dead astern, the even fixedly connected with reflector panel in bevel window, the drain tank has been seted up to the bottom of fender pile and. When meetting the vehicle striking, the fender pile can have the strength of certain buffering when accepting the impact force that the striking produced to the built-in part that can rotate that has produces the rotation effect when contacting with the vehicle, has reached the effect to the impact force dispersion to a certain extent, has alleviated the damage that partly striking produced the fender pile, has improved the security of bridge railing effect.
