Combined prefabricated bridge guardrail

Abstract

The invention discloses a combined prefabricated bridge guardrail. The guardrail comprises a concrete anti-collision wall body, a steel structure stand column, a steel anti-collision guardrail, a steel pipe guardrail and a concrete hanging plate, wherein the concrete anti-collision wall body is prefabricated in a factory, and the anti-collision requirement is met. The steel structure stand columnplays a role in fixing of a steel pipe cross beam, and the steel anti-collision guardrail acts as an anti-collision beam, and the steel pipe guardrail is provided with a LED lamp strip for achieving the effect of road illumination. After the concrete anti-collision wall body is installed, a longitudinal seam exists with the side surface of a bridge deck, in order to achieve the whole attractiveness effect, the concrete hanging plate is used for shielding, and meanwhile, the hanging plate plays a role in water dripping. The novel combined bridge guardrail is prefabricated in a factory and installed in a field, meanwhile, a guardrail lamp and the anti-collision guardrail are combined, bridge high-pole lamps and guardrail outer side backpacks are omitted, the whole construction period of a bridge can be shortened, meanwhile, the linear effect of a prefabricated part is more attractive, batch production can be achieved, the bridge guardrail can be suitable for a municipal road viaduct, andthe economic benefit is high.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a combined prefabricated bridge guardrail. Background technique [0002] At present, anti-collision guardrails in municipal bridge projects can be divided into reinforced concrete guardrails, steel structure guardrails and combined guardrails according to materials. The construction of most of the bridge anti-collision guardrails adopts on-site pouring after the main beam construction is completed. According to the existing project implementation experience, the use of cast-in-place reinforced concrete anti-collision barriers has disadvantages such as substandard appearance quality and slow construction speed. [0003] At this stage, with the promotion of prefabricated assembly technology, the prefabricated assembly technology of bridge crash barriers should have a wider application prospect. [0004] At the same time, the current road lighting in municipal bridge projects basically adop...

Problems solved by technology

[0004] At the same time, the current road lighting in municipal bridge projects basically adopts the form of pole street lights. In order to design the foundation of pole street lights, the bridge anti-collision guardrail adopts the form of an outer backpack, which has an impact on the overall facade of the bridge. The viaduct is not beautiful, so the lighting The form combined with the anti-collision barrier can be applied to engineering practice
