Technical Field

[0001] The present invention relates to the technical field of sports facilities, in particular to a plastic running track. Background Art

[0002] The plastic track, also known as the all-weather track and field sports 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, improving athletic performance and reducing the probability of injury.

[0003] The existing plastic tracks are mainly made by mixing polyurethane, rubber and other materials into a viscous rubber, which is then spread and cured on site. Different colors can be set as needed, and it has certain UV resistance and aging resistance.

[0004] With the development of social economy, people pay more and more attention to their health, and the demand for sports venues is becoming more urgent. However, since plastic tracks are mostly used in open-air venues, their performance is easily affected by climatic conditions. After a period of use, the existing plastic tracks are greatly affected by temperature and humidity, and irregular cracks will appear. The existence of these cracks reduces the elasticity of the plastic track and even causes cracks, resulting in unstable performance, poor durability, and short service life of the plastic track.

[0005] Therefore, how to provide a plastic track with excellent performance, stability, good durability and long service life has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0029] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0030] Please Figures 1 to 3 As shown, the present invention provides a plastic track, including an elastic base layer 1, a reinforcement layer 2, and an anti-skid layer 3 arranged in sequence from bottom to top; a plurality of positioning holes 11 are provided on the upper surface of the elastic base layer 1, and a positioning piece 21 matching with the positioning hole 11 is provided on the lower surface of the reinforcement layer 2; rubber particles are distributed on the surface of the anti-skid layer 3.

[0031] The existing plastic track is greatly affected by the environment (humidity, temperature) during construction, and the comprehensive performance of the product after molding (mainly impact absorption and vertical deformation) is also easily affected by the climate. In order to improve the quality of the plastic track, the present invention provides a plastic track, including an elastic base layer 1, a reinforcing layer 2, and an anti-skid layer 3 arranged in sequence from bottom to top. Specifically, in order to enhance the tightness of the connection between the elastic base layer 1 and the reinforcing layer 2, the present application provides a plurality of positioning holes 11 on the upper surface of the elastic base layer 1, and a positioning piece 21 that cooperates with the positioning hole 11 is provided on the lower surface of the reinforcing layer 2; through the cooperation of the positioning piece 21 and the positioning hole 11, the relative movement between the reinforcing layer 2 and the elastic base layer 1 in the horizontal direction is limited, so that the assembly between the reinforcing layer 2 and the elastic base layer 1 is more stable. At the same time, the setting of the positioning hole 11 can also disperse the surface stress of the elastic base layer 1, improve the impact strength of the elastic base layer 1, and prevent it from aging and cracking. Furthermore, in order to increase the friction between athletes and the plastic track and prevent athletes from falling due to slipping during exercise, in the present application, rubber particles are distributed on the surface of the anti-slip layer 3. The provision of rubber particles can increase the roughness of the surface of the plastic track and achieve an anti-slip effect.

[0032] The elastic base 1 of the plastic track provided by the present invention is prefabricated in a factory and then transported to the site for direct laying. After the elastic base 1 is laid on the foundation, an adhesive is spread to form a reinforcing layer 2. The adhesive can penetrate into the positioning hole 11 of the elastic base 1 and form a positioning piece 21 embedded in the positioning hole 11 after solidification, thereby playing a role in firmly connecting the foundation and the elastic base 1. After the reinforcing layer 2 is solidified, an anti-skid layer 3 is spread on the surface of the reinforcing layer 2.

[0033] The plastic track provided in this application is easy to lay, can speed up the construction progress, and reduce the probability of being affected by climatic conditions during outdoor construction, thereby improving the quality of the prepared plastic track and effectively reducing the labor intensity of workers.

[0034] In addition, the plastic track has high elasticity, good impact resistance and shock absorption properties, and can effectively protect athletes from knee injuries due to the high hardness of the ground during exercise. At the same time, the plastic track has high flatness, stable performance, good weather resistance, and a long service life.

[0035] Preferably, the positioning hole 11 communicates the upper surface and the lower surface of the elastic base layer 1 .

[0036] In the present application, the positioning hole 11 can be vertically arranged in the elastic base layer 1, or can be inclined at a certain angle, as long as it is not parallel to the upper surface of the elastic base layer 1, the positioning hole 11 can connect the upper surface and the lower surface of the elastic base layer 1. Preferably, the positioning hole 11 is vertically arranged to facilitate the pouring of the adhesive to form the reinforcement layer 2.

[0037] Preferably, the inner wall of the positioning hole 11 is provided with a groove, and correspondingly, the outer wall of the positioning member 21 is provided with a protrusion matching the groove.

[0038] The cooperation between the groove and the protrusion can further enhance the stability of the assembly between the reinforcing layer 2 and the elastic base layer 1 .

[0039] Preferably, the elastic base layer 1 is made of PVC foam material.

[0040] The elastic base layer 1 used in the present application is preferably made of PVC foam material, which has many holes inside, which is beneficial to the impact absorption of the runway and can provide stable impact absorption and vertical deformation performance for the plastic runway.

[0041] Preferably, the anti-slip layer 3 is made of polyurethane, and / or the reinforcement layer 2 is made of polyurethane.

[0042] Preferably, the reinforcement layer 2 and the positioning piece 21 disposed on the lower surface of the reinforcement layer 2 are integrally formed.

[0043] Specifically, the preferred step of forming the reinforcing layer 2 is to first pour the reinforcing layer 2 raw material into the positioning hole 11 of the elastic base layer 1, so that the reinforcing layer 2 raw material penetrates into the positioning hole 11 and can contact the foundation below the elastic base layer 1, and then continue to pour the reinforcing layer 2 raw material to form the reinforcing layer 2. The formed reinforcing layer 2 and the reinforcing layer 2 raw material poured into the positioning hole 11 form a whole, so that the elastic base layer 1 and the reinforcing layer 2 are more firmly combined, thereby improving the quality of the plastic track.

[0044] Preferably, a buffer layer may be provided on the reinforcing layer 2, and the buffer layer and the reinforcing layer 2 may be connected via an adhesive. Specifically, the buffer layer may also be made of polyurethane.

[0045] Preferably, the thickness of the elastic base layer 1 is 4-7 mm, and more preferably 5-6 mm.

[0046] Preferably, the thickness of the reinforcement layer 2 is 4-7 mm, and more preferably 5-6 mm.

[0047] Preferably, the thickness of the anti-slip layer 3 is 2-4 mm; more preferably 2.5-3.5 mm.

[0048] The present application can obtain a plastic track with excellent impact resistance and buffering properties by selecting an elastic base layer 1, a reinforcing layer 2, and an anti-slip layer 3 of appropriate thickness.

[0049] Preferably, reinforcing fibers 31 are distributed inside the anti-slip layer 3 .

[0050] The provision of the reinforcing fibers 31 helps to improve the impact resistance and crack resistance of the anti-slip layer 3 .

[0051] Preferably, the reinforcing fiber 31 is one or more of aramid fiber, orlon fiber, polyester fiber, nylon fiber, vinylon fiber, polypropylene fiber, polyimide fiber, cotton fiber, glass fiber, carbon fiber, boron fiber, whisker, asbestos fiber, and metal fiber.

[0052] Preferably, a waterproof layer 4 is provided between the reinforcing layer 2 and the anti-slip layer 3, and a longitudinal drainage groove 41 and a transverse drainage groove 42 are provided on the upper surface of the waterproof layer 4. The longitudinal drainage groove 41 and the transverse drainage groove 42 are connected, and the bottom surfaces of the longitudinal drainage groove 41 and the transverse drainage groove 42 are arched surfaces protruding upward.

[0053] The bottom surfaces of the longitudinal drainage groove 41 and the transverse drainage groove 42 are set to be upwardly protruding arched surfaces, so that the water that penetrates from the anti-slip layer 3 into the surface of the waterproof layer 4 can flow to both sides of the drainage groove under the guidance of the arched surface, and then be discharged from the outer edge of the waterproof layer 4. This arrangement can effectively reduce the accumulation of water on the surface and inside of the plastic track, and prevent the plastic track from swelling and cracking due to the effect of water seepage.

[0054] Preferably, a reinforcement grid 22 is provided inside the reinforcement layer 2 .

[0055] The provision of the reinforcing grid 22 can effectively improve the crack resistance and integrity of the reinforcing layer 2, and prevent the reinforcing layer 2 from cracking due to hardening due to aging.

[0056] Preferably, the reinforcing grid 22 is one or more of a glass fiber grid, a steel wire grid, a plastic grid, and a hemp rope grid.

[0057] Preferably, the interior of the anti-slip layer 3 is doped with aromatic particles.

[0058] Since the plastic track is made of polymer materials or rubber, most of them have a strong odor. In order to improve this situation, aromatic particles can be mixed inside the anti-slip layer 3. Among them, the fragrance type of the aromatic particles can be selected according to different needs, such as lavender fragrance can soothe emotions, reduce anger and exhaustion, and balance the central nervous system; jasmine fragrance can improve insomnia and anxiety; rosemary can enhance memory, refresh the mind, and relieve headache symptoms; apple fragrance has an obvious effect of eliminating psychological depression; orange fragrance can eliminate the tension and anxiety caused by the depressing atmosphere and make people relax.

[0059] Preferably, the surface of the anti-slip layer 3 is provided with a marking line, and a fluorescent layer is provided on the marking line.

[0060] The setting of the fluorescent layer can prevent athletes from not being able to see the ground conditions clearly when there is insufficient light at night, which affects their normal walking.

[0061] The embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other.
