Description

Technical Field

[0001] The utility model relates to the field of environmentally friendly prefabricated plastic runways, and more specifically, to an environmentally friendly prefabricated plastic runway. Background Art

[0002] The plastic track is also called the all-weather track for athletics. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. The plastic track has a certain elasticity and color, and has a certain UV resistance and aging resistance. It is internationally recognized as the best all-weather outdoor sports field floor material. The plastic track is used in kindergartens, schools of all levels and types, professional stadiums, track and field tracks, semicircular areas, auxiliary areas, national fitness paths, indoor gymnasium training tracks, playground road paving, indoor and outdoor tracks, tennis, basketball, volleyball, badminton, handball and other venues, parks, residential areas and other activity venues. The plastic track is non-toxic and harmless to the environment and human body. The plastic track has the characteristics of anti-ultraviolet light, anti-wear, anti-explosion, anti-aging, long life, easy maintenance, and low maintenance cost. The prefabricated plastic track is a kind of plastic track. The prefabricated plastic track fully considers the biomechanical needs of athletes during the planning process, reducing the impact during exercise; At present, the existing prefabricated plastic track is dense and airtight. At high temperature, the steam and water vapor generated by the foundation cannot diffuse quickly, and the prefabricated plastic track produces bubbling. In addition, the elastic support layer of the existing prefabricated plastic track is generally a solid layer filled with a material with deformation ability, and its buffering effect is limited, which cannot well guarantee the speed and technology of athletes.

[0003] In the prior art, such as authorization announcement number CN213389582U, it involves an environmentally friendly prefabricated plastic track, which includes a coarse asphalt layer, a gravel layer, a fine asphalt layer, a reinforcing support layer, a substrate layer, an elastic support layer and a breathable layer stacked in sequence; the substrate layer has a concave-convex surface on one side close to the reinforcing support layer to increase friction; the breathable layer has a self-cleaning pattern on one side away from the elastic support layer. The environmentally friendly prefabricated plastic track of the utility model has excellent air permeability, which can quickly and effectively exhaust and drain air, and prevent the environmentally friendly prefabricated plastic track from bubbling. In addition, titanium dioxide can absorb ultraviolet rays in sunlight and convert nitrogen oxides in the air into pollution-free salts, so that the environmentally friendly prefabricated plastic track has the ability to purify the surrounding environment. A number of PU injection-molded elastic support columns are used to enhance the structural strength of the environmentally friendly prefabricated plastic track. At the same time, a number of PU injection-molded elastic support columns have good cushioning, ductility and strong adhesion, ensuring that athletes can give full play to their speed and skills.

[0004] In the above-mentioned patent, glue is used to bond at various levels, and the surface layer is easy to be damaged. When in use, it is easy to be broken and damaged. When replacing it, it is necessary to shovel other surface layers for replacement, which is inconvenient. After the bottom is bonded to cement, it is easy to be corroded from the edge gaps, easy to hollow out and water enters, and it is inconvenient to drain the bottom. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an environmentally friendly prefabricated plastic track, which adopts a surface clip-on structure and can be easily assembled and disassembled through a strip-shaped buckled protrusion and a recessed connecting groove clip-on structure.
