Plastic curb and plastic curbstone forming same

Abstract

The invention relates to a plastic curbstone, which is made of plastic materials and comprises a horizontal hollow body and projecting edges extending out from bottom edges of the hollow body. The hollow body comprises a bottom plate, a top plate, a front plate and a rear plate. The top plate is connected between the top end of the front plate and the top end of the rear plate. The bottom plate is connected between the bottom end of the front plate and the bottom end of the rear plate. The bottom plate, the top plate, the front plate and the rear plate enclose a cavity transversely penetrating two ends of the hollow body. The plastic curbstone is light in weight, convenient in processing, transport and installation, low in cost and recyclable. The invention further relates to a plastic curb comprising the plastic curbstones. Each two adjacent plastic curbstones are tightly fitted and connected together through connectors. The plastic curb is convenient in installation and firm and is capable of effectively alleviating harm to vehicles and persons inside when the vehicles crash against the plastic curb.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a plastic curb and its plastic curb stones, which can be used on the edges of roads, flower beds, site surfaces, green belts, etc. to demarcate the range of the road surface, tidy the road capacity, protect the edge of the road surface and guide and exclude road water etc. Background technique [0002] At present, on the edges of roads, flower beds, site surfaces, green belts, etc., curbstones are often set up to mark the range of the road surface, tidy the road capacity, protect the edge of the road surface, and guide the removal of road water. Existing curbs are usually solid strips prefabricated by concrete or processed by natural stone, which have the following disadvantages: low degree of mechanization of production, long production and maintenance period; There are many defective products; the weight is heavy and the transportation cost is high; because the curb is solid ...

AI Technical Summary

Problems solved by technology

Existing curbs are usually solid strips prefabricated by concrete or processed by natural stone, which have the following disadvantages: low degree of mechanization of production, long production and maintenance period; There are many defective products; the weight is heavy and the transportation cost is high; because the curb is solid and heavy, it not only wastes materials, but also increases the labor intensity of workers, which is labor-intensive; during construction, the joint between two adjacent curbs is usually The joints are sealed with cement mortar to control the overall stability in the length direction. However, with the passage of time and the influence of climate, etc., the gap between the joints of two adjacent curbs will be reduced due to changes in deformation stress or certain external forces. It is easy to crack, butt joints are easy to dislocate, forming the common quality problems of curb stones leaning forward and backward, and uneven quality. Moreover, the joint width of curb stones is required to be uniform, which brings difficulties to construction, and the construction speed is slow. It is easy to form cavities, and it is not easy to be found, resulting in joints that are not dense, and the construction quality cannot be guaranteed; during use, when a traffic accident occurs, the vehicle and the curb are prone to hard collision, which is easy to cause damage to the vehicle and the personnel on the vehicle. Fatal injury; In addition, after the curb stone is damaged, it is difficult to repair due to installation difficulties and cannot be recycled and reused
