Description

Technical Field

[0001] The utility model relates to the technical field of plastic runways, in particular to a durable plastic runway. 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, effectively improving sports performance and reducing the rate of falls.

[0003] There are many inconveniences in the existing plastic runway design:

[0004] First, the adhesion of the plastic track is not enough. Although the force generated by human movement and the friction during running are not enough to move the surface layer of the plastic track and cause it to be dislocated, the playground often requires large machinery to maintain the lawn or perform other operations. At this time, it is easy for the anti-slip surface layer of the plastic track to be dislocated from the bottom layer, resulting in the phenomenon of peeling of the anti-slip surface layer of the plastic track;

[0005] Second, the main reason why the service life of current plastic tracks is generally lower than the designed life is the problem of moisture content. Since plastic tracks are exposed to the external environment all year round, when encountering rainy seasons, seepage water accumulates in the bottom layer, and the hardness of the soil in the bottom layer changes, which in turn causes the surface layer to bend and become uneven, reducing the service life of the plastic track. Utility Model Content

[0006] The utility model provides a durable plastic running track, which utilizes a three-dimensional net as an elastic skeleton body and is positioned and shaped by an adhesive layer, thereby avoiding the problem of deformation and dislocation of the running track.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a durable plastic track, comprising: a three-dimensional net, the three-dimensional net covers the surface of the ground base layer, and the lower half of the three-dimensional net is infiltrated with an adhesive layer, and the three-dimensional net is bonded and fixed to the ground base layer through the three-dimensional net; an elastic buffer layer, the elastic buffer layer infiltrates the upper half of the three-dimensional net, and the top of the elastic buffer layer is higher than the three-dimensional net; a granular layer, the granular layer is attached to the top of the elastic buffer layer.

[0008] Preferably, it further comprises U-shaped nails, through which the three-dimensional net is fixedly connected to the ground base layer, and the U-shaped part at the top of the U-shaped nails is bound to the multiple network structures of the three-dimensional net.

[0009] Preferably, it also includes positioning nails, which penetrate the adhesive layer and extend into the ground base layer.

[0010] Preferably, it also includes an embedded bracket, which includes a positioning sleeve and a plurality of elastic arms connected around the positioning sleeve; the embedded bracket is mounted on the positioning pin through the positioning sleeve, and each of the elastic arms extends radially into the network structure of the three-dimensional mesh.

[0011] Preferably, it also includes a waterproof adhesive layer, which is arranged on the top of the adhesive layer and covers the positioning pins and the embedded bracket.

[0012] The utility model has the beneficial effects that the adhesive layer is used for positioning and solidifying the three-dimensional net. When the ground base is a flat land or gravel surface, the adhesive layer realizes the splicing and positioning of the three-dimensional net, and hardens the bottom half of the three-dimensional net to ensure the laying shape and avoid deformation; when the ground base is a paved surface such as cement or asphalt, the adhesive layer not only splices and solidifies the three-dimensional net, but also firmly adheres and fixes the three-dimensional net to the ground base, thereby avoiding the overall displacement of the three-dimensional net. The elastic buffer layer sparsely fills the gaps in the upper half of the three-dimensional net, thereby improving the supporting capacity of the three-dimensional net, and ensures that the three-dimensional net has a certain elastic buffering effect with the help of the gaps; the granular layer provides good friction for the surface of the plastic runway. The three-dimensional net is used as the elastic skeleton body in the plastic runway, and is positioned and shaped by the adhesive layer, thereby avoiding the problem of deformation and dislocation of the runway. The U-shaped nail is used to fix the three-dimensional net and the ground base, mainly solving the problem of connecting and fixing the three-dimensional net on the land or gravel ground. The positioning nail fixes the overall three-dimensional net through the adhesive layer. The embedded bracket is used together with the positioning nail. During the process of drilling the positioning nail, the multiple elastic arms of the embedded bracket are guided by the ground base and dispersed around, inserted flatly into the network structure of the three-dimensional mesh, thereby achieving a wide range of fixed constraints. The waterproof adhesive layer is used to enhance the waterproof effect of the adhesive layer and fill the holes and gaps of the U-shaped nails and positioning nails to prevent moisture from penetrating into the ground base, thereby improving the life and flatness of the ground base.

[0019] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] according to Figure 1 As shown, a durable plastic track includes: a three-dimensional net 1, which covers the surface of a ground base layer 2, and the lower half of the three-dimensional net 1 is infiltrated with an adhesive layer 3, and the three-dimensional net 1 is bonded and fixed to the ground base layer 2 through the three-dimensional net 1; an elastic buffer layer 4, which infiltrates the upper half of the three-dimensional net 1, and the top of the elastic buffer layer 4 is higher than the three-dimensional net 1; a granular layer 5, and the granular layer 5 is attached to the top of the elastic buffer layer 4.

[0021] Through the above arrangement, the adhesive layer 3 is used for positioning and solidifying the three-dimensional net 1. When the ground base 2 is a flat land or gravel surface, the adhesive layer 3 realizes the splicing and positioning of the three-dimensional net 1, and hardens the bottom half of the three-dimensional net 1 to ensure the laying shape and avoid deformation; when the ground base 2 is a paved surface such as cement or asphalt, the adhesive layer 3 not only splices and solidifies the three-dimensional net 1, but also firmly adheres and fixes the three-dimensional net 1 to the ground base 2, thereby avoiding the overall displacement of the three-dimensional net 1. The elastic buffer layer 4 sparsely fills the gaps in the upper half of the three-dimensional net 1, thereby improving the supporting capacity of the three-dimensional net 1, and ensures that the three-dimensional net 1 has a certain elastic buffering effect with the help of the gaps; the granular layer 5 provides good friction for the surface of the plastic track.

[0022] according to Figure 2 As shown, it also includes U-shaped nails 6, and the three-dimensional net 1 is fixedly connected to the ground base layer 2 through the U-shaped nails 6, and the U-shaped part on the top of the U-shaped nails 6 is bound to the multiple groups of network structures of the three-dimensional net 1.

[0023] The U-shaped nails 6 in the above arrangement are used to fix the three-dimensional net 1 to the ground base 2, and mainly solve the problem of connecting and fixing the three-dimensional net 1 on the land or gravel ground.

[0024] according to Figure 3 As shown, it also includes positioning nails 7, which penetrate the adhesive layer 3 and extend into the ground base layer 2. The positioning nails 7 in this arrangement fix the entire three-dimensional net 1 through the adhesive layer 3.

[0025] It also includes an embedded bracket, which includes a positioning sleeve 9 and a plurality of elastic arms 10 connected around the positioning sleeve 9; the embedded bracket is sleeved on the positioning pin 7 through the positioning sleeve 9, and each of the elastic arms 10 extends radially into the network structure of the three-dimensional net 1.

[0026] In this setting, the embedded bracket is used together with the positioning nail 7. During the process of drilling the positioning nail 7, the multiple elastic arms 10 of the embedded bracket are guided by the ground base layer 2 and dispersed around and inserted flatly into the network structure of the three-dimensional net 1, thereby achieving a large range of fixed constraints.

[0027] according to Figure 4 As shown, it also includes a waterproof adhesive layer 11, which is arranged on the top of the adhesive layer 3, and the waterproof adhesive layer 11 covers the positioning nails 7 and the embedded bracket.

[0028] In this configuration, the waterproof adhesive layer 11 is used to enhance the waterproof effect of the adhesive layer 3 and fill the holes and gaps of the U-shaped nails 6 and the positioning nails 7 to prevent moisture from penetrating into the ground base layer 2, thereby improving the life and flatness of the ground base layer 2.
