Description

Guardrail and road guardrail structure

Technical Field

The application relates to the technical field of road traffic, particularly, relate to a guardrail and road guardrail structure.

Background

The road guardrail is a traffic safety facility used for isolating different functional areas of urban roads and is mainly applied to positions such as the outer sides of road shoulders, traffic separation zones, pedestrian roads and the like. The traffic guiding device plays important roles of guiding traffic, protecting pedestrians and the like by blocking vehicles or pedestrians from entering the moving area of the opposite side in traffic.

After the conventional urban road guardrail is used for a period of time, the phenomenon that the guardrail is polluted due to long-time wind, sunshine, automobile tail gas and urban sewage can be caused; in addition, small advertisements and various doodles which appear sometimes are stuck on the guardrail and can obstruct the view, so that a city cleaning department can regularly use cleaning vehicles and personnel to clean the guardrail, but stains on the surface of the guardrail are not easy to clean, so that sanitation personnel need to manually clean the stains which are difficult to clean on the guardrail, manpower and material resources are wasted, and the workload of sanitation workers is increased.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a guardrail and road guardrail structure can effectively solve the difficult clear problem of road guardrail, has improved the aesthetic property of urban road railing, has reduced sanitationman's work load.

In a first aspect, an embodiment of the present application provides a guardrail, which is applied to a road, and includes a guardrail main body and a self-cleaning functional coating, wherein the self-cleaning functional coating is coated on the guardrail main body; the self-cleaning functional coating comprises a self-cleaning functional finish paint layer, and the self-cleaning functional finish paint layer is coated on the guardrail main body, so that stains on the guardrail main body are not easy to attach and are easy to clean.

In this scheme, through having coated self-cleaning function coating in the guardrail main part, can utilize self-cleaning function finish paint layer in the self-cleaning function coating to coat in the surface of guardrail main part, self-cleaning function finish paint layer plays to wait and self-cleaning effect, outside various stain the adhesive force on the surface of self-cleaning function finish paint layer all less strong, make the spot on guardrail surface easily wash, when the rivers of rainwater or watering lorry pass through, can take away the spot on guardrail surface, make the surface of guardrail clean as new, played the function of beautifying urban environment, resident's comfort level has been improved, and because the guardrail easily washs, do not need the manual washing of sanitationman, sanitationman's work load has been reduced greatly.

In some embodiments, the self-cleaning functional coating further comprises an anti-corrosive primer layer applied to a surface of the guardrail body.

Among the above-mentioned technical scheme, be equipped with anticorrosive priming paint layer through scribbling on the surface of guardrail main part, because the osmotic force and the adhesive force of priming paint are all stronger, so anticorrosive priming paint layer can let the adhesive force between self-cleaning function finish paint layer and the guardrail main part obtain improving, avoids the later stage to appear the phenomenon that self-cleaning function finish paint layer drops to anticorrosive priming paint layer can improve the anticorrosive and alkali resistance of guardrail main part, has reduced the probability that guardrail main part is corroded, has correspondingly prolonged the life of guardrail.

In some embodiments, the self-cleaning functional coating further comprises a polyurethane intermediate paint layer located between the anti-corrosive primer layer and the self-cleaning functional topcoat layer.
