Description

Technical Field

[0001] This utility model relates to the field of plastic running track equipment technology, and specifically to a composite plastic running track. Background Technology

[0002] Synthetic running tracks, also known as all-weather athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, and fillers. Synthetic running tracks are an indispensable facility in modern athletic fields. Compared to traditional dirt tracks, they offer superior elasticity, slip resistance, wear resistance, shock absorption, ease of maintenance, vibrant colors, and a neat, aesthetically pleasing appearance. In competitive sports, synthetic tracks are more conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and knee injuries. Synthetic running tracks can be categorized based on their structure into all-synthetic, mixed-material, and composite types.

[0003] A typical plastic running track generally includes the following structural layers (from top to bottom): surface wear-resistant layer (EPDM granules + PU bonding layer), elastic layer (PU or rubber granules + glue mixture layer), bonding layer (bottom layer bonded to elastic layer), and base layer (asphalt or concrete).

[0004] While existing plastic running tracks have good cushioning performance, their drainage effect is poor, and water easily accumulates on the surface of the track. Water reduces the coefficient of friction, and condensation on the surface, especially after rain or sudden temperature changes, can easily cause athletes to fall. In addition, long-term immersion in water can cause the polyurethane or rubber materials to hydrolyze, foam, harden or soften, reducing elasticity and affecting the service life of the track. Utility Model Content

[0005] The purpose of this invention is to provide a composite plastic running track that solves the problem of poor drainage performance of traditional plastic running tracks.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] like Figure 1-3 As shown in the figure, the composite plastic running track described in this embodiment includes a rubber granule layer 1;

[0028] A permeable layer 2 is attached to the lower part of the rubber granule layer 1 by an adhesive. The permeable layer 2 is used to guide the water that accumulates on the upper part of the rubber granule layer 1 and prevent water from accumulating on the surface of the rubber granule layer 1.

[0029] A water-passing layer 3 is disposed below the permeable layer 2. The water-passing layer 3 is used to drain the accumulated water from the permeable layer 2, thereby improving the drainage performance of the plastic running track.

[0030] Buffer layer 4 is attached to the lower part of the water-passing layer 3. The buffer layer 4 is used for track shock absorption and to protect the athletes' joints.

[0031] Concrete layer 5, which is disposed below the buffer layer 4;

[0032] By setting up a permeable layer 2 and a water-passing layer 3, the drainage performance of the plastic running track is greatly enhanced, effectively preventing the formation of water accumulation on the rubber granule layer 1, and also avoiding the problem of reduced service life caused by long-term immersion of the rubber granule layer 1 in water.

[0033] The permeable layer 2 includes a permeable plate 21 and permeable holes 22. Multiple permeable holes 22 are provided, and the multiple permeable holes 22 are arrayed on the permeable plate 21.

[0034] The water-passing layer 3 includes a water-passing plate 31 and a water-passing groove 32. Multiple water-passing grooves 32 are provided, and the multiple water-passing grooves 32 correspond to the water-permeable holes 22.

[0035] The buffer layer 4 is made of EPDM particles bonded together with an adhesive.

[0036] The thickness of the water-passing layer 3 is 15 mm.

[0037] The thickness of the permeable layer 2 is 25 mm.

[0038] Working principle

[0039] When draining accumulated water, the water passes through the rubber granule layer 1 into the permeable layer 2, and then flows through the permeable holes 22 into the water-passing layer 3. Under the guidance of the water-passing trough 32, the accumulated water is discharged from the plastic track.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
