Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering, in particular to a multifunctional landscape anti-collision guardrail. Background Art

[0002] Anti-collision guardrails refer to facilities installed on both sides of roads or bridges to protect the safety of vehicles and pedestrians. With the continuous development of urban traffic and the increasing demand for traffic safety, the role and landscape of anti-collision guardrails have become increasingly prominent. Generally, anti-collision guardrails can be divided into two categories: hollow metal guardrails and wall guardrails.

[0003] Hollow metal guardrail has the following characteristics:

[0004] The components of hollow metal guardrails are mostly prefabricated in the factory and transported to the site for installation. They are easy to operate, have a short construction period, good anti-collision effect, and the components can be replaced at any time without affecting traffic. The later maintenance cost is low. However, hollow metal guardrails have poor visual shielding effects, bring a sense of panic, and are prone to high-altitude throwing. In addition, rainwater can easily splash under municipal bridges, affecting pedestrians and vehicles below.

[0005] Wall guardrail has the following characteristics:

[0006] Concrete wall guardrails have strong protective capabilities and low construction costs. They are currently the most widely used guardrail structure. However, in the context of the current era of rapid construction, the problems in the construction of concrete guardrails cannot be ignored: large on-site steel bar binding, difficult high-altitude edge concrete pouring, high construction safety risks, and long construction periods. During operation, concrete wall guardrails are prone to surface cracking and are difficult to repair. Steel structure wall guardrails have small welding space, are difficult to operate on site, and have complex processes, which can easily lead to weld defects in the later stage.

[0007] In summary, both types of guardrails have certain shortcomings: the landscape effect is not good, especially the anti-collision guardrails on municipal bridges do not reflect the corresponding landscape quality. The hollow metal guardrail has a poor water-blocking effect, and large areas of rain often splash under the bridge, affecting the passage of pedestrians or vehicles below. The visual shielding effect is poor, which brings a sense of panic and is prone to throwing objects from high places. Concrete wall guardrails require a large amount of steel bar tying on site, it is difficult to pour concrete at high altitude edges, the construction safety risks are high, and the construction period is long. It is easy to crack in the later stage and is difficult to repair. The welding space of the steel structure wall guardrail is small, it is not easy to operate on site, the process is complicated, and it is easy to cause weld defects in the later stage.

[0011] Furthermore, the side connecting plates of the protective metal plate are connected to the webs of the steel columns by self-tapping screws.

[0012] Furthermore, the protective metal plate water-facing plate is connected to the upper end of the steel column through a steel column groove.

[0013] Furthermore, the bottom connecting plate of the protective metal plate is connected to the top plate of the guardrail steel base by self-tapping screws.

[0015] Furthermore, the steel column is a rectangular structure formed by welding a front wall plate, a rear wall plate and a web plate.

[0016] Furthermore, the guardrail base is welded by a base top plate, a base web plate, a base bottom plate and a base partition plate.

[0017] Correspondingly, the utility model also provides a construction method of a multifunctional landscape anti-collision guardrail, the main steps of which are as follows:

[0023] The guardrail is composed of a guardrail steel base, steel columns, metal cross pipes, protective metal plates and embedded bolts. Each component is connected by welding and bolts, with a simple structure and easy construction and installation.

[0024] The guardrail steel base is welded and fixed to the top plate of the steel main beam, the steel column is connected to the metal cross pipe through a connecting sleeve, and the protective metal plate is connected to the steel base and steel column through self-tapping screws. This connection method ensures the stability and reliability of the guardrail.

[0025] A protective metal plate is added to the outside of the guardrail to effectively prevent water splashing under the bridge during driving, and can also divert water to the bridge deck drainage system. The protective metal plate can also reduce light pollution from vehicles at night and prevent light dazzle from oncoming traffic. In addition, the protective metal plate can be inlaid with lights to enhance the lighting effect at night and have a good landscape effect.

[0026] The guardrail can be applied to steel structure anti-collision guardrails and non-anti-collision guardrails with large crossbar spacing. Compared with traditional hollow metal guardrails, the guardrail of the utility model can reduce the risk of falling objects from high altitude.

[0027] The utility model has good adaptability and is not only suitable for steel structure anti-collision guardrails, but also suitable for non-anti-collision guardrails with larger cross bar spacing. The risk of falling objects from high altitude in the later stage is lower than that of traditional guardrails. BRIEF DESCRIPTION OF THE DRAWINGS
