Description

Technical Field

[0001] The utility model relates to the technical field of runways, in particular to an elastic layer structure of a runway. Background Art

[0002] A runway is a road used for running, speed skating, racing, etc. on a sports field. It also refers to a long strip of land at an airport for aircraft to take off or land. A runway can be paved with asphalt or concrete, or flattened grass, mud, or gravel.

[0003] At present, the plastic running track used for athletes is generally composed of a surface layer, a middle layer, a buffer layer and a base layer structure. However, as far as the current running track is concerned, its hardness is still relatively high, which often gives people a feeling of discomfort after or during exercise, thereby reducing the use effect of the plastic running track. Based on this, we propose a running track elastic layer structure. Utility Model Content

[0008] The elastic layer comprises an elastic top layer and an elastic bottom layer, and is respectively bonded and fixed on the buffer layer and the middle layer.

[0009] The base layer is a concrete layer or an asphalt layer.

[0010] The beneficial effects of the utility model are:

[0011] Compared with the prior art, the utility model is provided with an elastic layer and is composed of an elastic top layer and an elastic bottom layer, which can greatly enhance the elastic performance of the plastic track, reduce the hardness of the track, enhance the comfort of athletes during exercise, and thus improve the use effect of the plastic track; it is highly practical.

[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0015] like Figure 1 As shown,

[0016] A runway elastic layer structure comprises a base layer 1, a moisture-proof layer 2, a buffer layer 3, an elastic layer 4, an intermediate layer 5 and a surface layer 6; the top surface of the base layer 1 is sequentially provided with the moisture-proof layer 2, the buffer layer 3, the elastic layer 4, the intermediate layer 5 and the surface layer 6; the elastic layer 4 comprises an elastic top layer 7 and an elastic bottom layer 8, which are respectively bonded and fixed to the buffer layer 3 and the intermediate layer 5; in the present application, the layers are fixed by bonding, or by coating and bonding.

[0017] As a preferred embodiment, the base layer 1 is a concrete or asphalt pavement layer; the base layer 1 is mainly used to provide a stable foundation support; and the concrete or asphalt material used has a better use effect.

[0018] As a preferred embodiment, the moisture-proof layer 2 is a polyethylene film layer; the polyethylene film is a PE film, which is a film produced from PE particles. The PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can be manufactured into products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene according to different manufacturing methods and control means to meet product requirements, with the purpose of enhancing the moisture-proof performance of the runway.

[0019] As a preferred embodiment, the buffer layer 3 is a rubber layer; rubber has strong buffering properties and can enhance the buffering effect of the runway.

[0020] As a preferred embodiment; the elastic top layer 7 is a thermoplastic carbon fiber composite material layer; this layer is a carbon fiber reinforced thermoplastic composite material, which has high strength, high specific modulus, excellent thermal properties and chemical stability, as well as damping, shock absorption and noise reduction properties, and is an excellent reinforcement material; so that the overall elastic effect is better; it is worth mentioning that for the runway, the material used cannot be too soft (too soft is not conducive to exercise), and the significance of increasing the elasticity is to make it have a stronger damping and shock absorption effect.

[0021] As a preferred embodiment, the elastic bottom layer 8 is a PEEK material layer. Polyetheretherketone (PEEK) is a polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, and is a special polymer material. It also has a better shock-absorbing and damping effect, and combined with the use of a thermoplastic carbon fiber composite material layer, it can greatly enhance the elastic properties of the plastic track, reduce the hardness of the track, and enhance the comfort of athletes during exercise.

[0022] As a preferred embodiment, the middle layer 5 is a PVC material layer; polyvinyl chloride plastic is formed by the polymerization of vinyl chloride monomer and is one of the commonly used thermoplastics; after application, it can increase the strength of the runway.

[0023] As a preferred embodiment, the surface layer 6 is a color coating layer. By providing the color coating layer, the track is made more sporty and the use effect is improved.

[0024] It should be pointed out that the main problems in the prior art are: as far as the current running track is concerned, its hardness is still relatively high, which often gives people a sense of discomfort after or during exercise, thereby reducing the use effect of the plastic running track;

[0025] Therefore, after the improvement of the present application, by providing an elastic layer 4 and being composed of an elastic top layer 7 and an elastic bottom layer 8, the elastic performance of the plastic track can be greatly enhanced, the hardness of the track can be reduced, and the comfort of athletes during exercise can be enhanced, thereby improving the use effect of the plastic track;

[0026] In addition, the elastic layer 4 is arranged between the middle layer 5 and the buffer layer 3. The middle layer 5 has greater strength. After being used with the elastic layer 4 (strength is maintained, and elastic effect is increased, and force rebound is achieved), the elastic performance of the runway can be increased as a whole. The bottom surface is the buffer layer 3, and the force rebound effect is also better.

[0027] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
