Description

Technical Field

[0001] This utility model relates to the field of plastic running track technology, specifically a multi-layer composite structure high wear-resistant plastic running track. Background Technology

[0002] Plastic running track materials are composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Plastic running tracks have the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to the speed and technique of athletes, effectively improving athletic performance and reducing the rate of falls and injuries. Plastic running tracks are composed of polyurethane rubber and other materials, and have a certain degree of elasticity and color. They also have a certain degree of UV resistance and aging resistance, and are internationally recognized as the best all-weather outdoor sports flooring material, commonly used in playground running tracks.

[0003] The wear resistance of existing plastic running tracks is directly affected by the construction quality. Foundation treatment is one of the key links to ensure the wear resistance life of the track. The existing tracks cannot squeeze and position the paving material on both sides, which causes deformation due to local collapse at the edges. At the same time, the foundation leveling process is poor, which cannot guarantee the levelness of the paving, and it is easy to cause local cracks in the track. This leads to phenomena such as blistering, cracking and delamination during use, which reduces its wear resistance and shortens its service life.

[0004] Therefore, this utility model provides a multi-layer composite structure of highly wear-resistant plastic running track to solve the above problems. Utility Model Content

[0005] This invention provides a multi-layer composite structure for a highly wear-resistant plastic running track, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite high wear-resistant plastic running track, including a cement foundation, with embedded parts inside the cement foundation, a metal base plate, a first metal drainage ditch, and a second metal drainage ditch above the cement foundation, with the top of the embedded parts extending through to the top of the metal base plate, the first metal drainage ditch fixedly connected to the outer side of the metal base plate, and the second metal drainage ditch fixedly connected to the inner side of the metal base plate, with filter screens provided on the side of the first and second metal drainage ditches near the metal base plate, and drainage pipes connecting the bottom of the first and second metal drainage ditches, and a cement thickening layer, a waterproof primer, an elastic particle layer, a PU elastic layer, and a polyurethane surface layer laid sequentially above the metal base plate.

[0007] As a preferred technical solution of this application, the top of the vertical end of the embedded part is an external thread structure, and a nut is connected to the external thread of the external thread structure, and the nut abuts against the upper surface of the metal base plate.

[0008] As a preferred technical solution of this application, the metal base plate is provided with a casting hole between adjacent embedded parts, and a concrete filling layer is high-pressure cast between the casting hole and the cement foundation.

[0009] As a preferred technical solution of this application, the bottom of the first metal drainage ditch and the second metal drainage ditch are both arc-shaped, and the lowest point of the arc-shaped structure corresponds to the drainage pipe in a through shape. The top of the first metal drainage ditch and the second metal drainage ditch are stepped inward, and a drainage ditch cover is fastened between the first metal drainage ditch and the second metal drainage ditch.

[0010] As a preferred technical solution of this application, the upper surface of the waterproof primer is above the bottom surface of the filter screen, and the edge of the waterproof primer covers the gap between the cement thickening layer, the first metal drainage ditch, and the second metal drainage ditch.

[0011] As a preferred technical solution of this application, the upper surface of the polyurethane surface layer is at the same level as the upper surfaces of the first metal drainage ditch and the second metal drainage ditch, and the upper surface of the drainage ditch cover plate is also at the same level as the upper surface of the polyurethane surface layer.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the setting of embedded parts and metal base plate, can quickly level the track during its laying, which not only improves the laying efficiency, but also effectively ensures the horizontality of the laying benchmark through the integrity and high strength of the metal plate, thereby avoiding cracks in the track due to local collapse, thus ensuring the integrity of the track and improving its wear resistance.

[0014] 2. This utility model sets metal drainage ditches on both sides of the track. The high strength of the metal helps to squeeze and position the track, preventing warping or collapse on both sides. This further improves the overall stability and tightness of the track after it is laid, thus ensuring its wear resistance.

[0015] 3. This utility model, through the setting of a high-efficiency drainage mechanism, can quickly discharge the infiltrated water source, thereby avoiding the accumulation of water inside and causing blistering or cracking, further improving the stability of the track and ensuring its wear resistance.

[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] like Figure 1-7As shown, this utility model provides a multi-layer composite high wear-resistant plastic running track, including a cement foundation 1, with embedded parts 2 inside the cement foundation 1. A metal base plate 3, a first metal drainage ditch 4, and a second metal drainage ditch 5 are arranged above the cement foundation 1, with the top of the embedded parts 2 extending through to the top of the metal base plate 3. The first metal drainage ditch 4 is fixedly connected to the outer side of the metal base plate 3, and the second metal drainage ditch 5 is fixedly connected to the inner side of the metal base plate 3. Filter screens 6 are provided on the side of the first metal drainage ditch 4 and the second metal drainage ditch 5 near the metal base plate 3. Drainage pipes 7 are connected through the bottom of the first metal drainage ditch 4 and the second metal drainage ditch 5. A cement thickening layer 9, a waterproof primer 10, an elastic particle layer 11, and a PU elastic layer are sequentially laid on top of the metal base plate 3. The elastic layer 12 and the polyurethane surface layer 13, through the cooperation of the metal base plate 3, the first metal drainage ditch 4 and the second metal drainage ditch 5, can assist in positioning the laid cement thickened layer 9, waterproof primer 10, elastic particle layer 11, PU elastic layer 12 and polyurethane surface layer 13, ensuring their overall firmness and stability, thereby effectively preventing blistering or cracking during use, thus improving their overall wear resistance and service life. The polyurethane surface layer 13 has good wear resistance and weather resistance, thereby improving its stability in harsh environments and ensuring its wear resistance effect. The main function of the elastic particle layer 11 and the PU elastic layer 12 is to provide elastic cushioning for the track and reduce the impact on the joints such as the knees and ankles of athletes during running.

[0027] Furthermore, the top of the vertical end of the embedded part 2 has an external thread structure, and the external thread structure is connected to a nut, which abuts against the upper surface of the metal base plate 3. The metal base plate 3 has a pouring hole between the adjacent embedded parts 2, and a concrete filling layer is poured under high pressure between the pouring hole and the cement foundation 1. The horizontal embedding of the embedded part 2 achieves stable installation of the metal base plate 3. At the same time, the high pressure pouring of concrete between the metal base plate 3 and the cement foundation 1 avoids the occurrence of hollowness, further improving the stability and firmness of the metal base plate 3.

[0028] Furthermore, the bottom of the first metal drainage ditch 4 and the second metal drainage ditch 5 are both arc-shaped, and the lowest point of the arc-shaped structure corresponds to the through-hole of the drainage pipe 7. The top of the first metal drainage ditch 4 and the second metal drainage ditch 5 are stepped inward, and a drainage ditch cover plate 8 is fastened between the first metal drainage ditch 4 and the second metal drainage ditch 5. Through the setting of the drainage pipe 7, the accumulated water inside the first metal drainage ditch 4 and the second metal drainage ditch 5 can be quickly guided and discharged.

[0029] Furthermore, the upper surface of the waterproof primer 10 is located above the bottom surface of the filter screen 6, and the edge of the waterproof primer 10 covers the gap between the cement thickening layer 9, the first metal drainage ditch 4, and the cement thickening layer 9 and the second metal drainage ditch 5. By covering the gap between the cement thickening layer 9, the first metal drainage ditch 4, and the cement thickening layer 9 and the second metal drainage ditch 5 with the waterproof primer 10, its waterproof performance is effectively improved, ensuring that water enters the first metal drainage ditch 4 and the second metal drainage ditch 5 through the filter screen 6 for collection. The upper surface of the polyurethane top layer 13 is at the same level as the upper surface of the first metal drainage ditch 4 and the second metal drainage ditch 5, and the upper surface of the drainage ditch cover plate 8 is also at the same level as the upper surface of the polyurethane top layer 13.

[0030] Working principle: First, the cement foundation 1 is poured, and the embedded parts 2 are embedded at the same time. Then, the metal base plate 3 is installed and positioned. At the same time, the first metal drainage ditch 4 and the second metal drainage ditch 5 are fixedly connected on the inner and outer sides of the metal base plate 3. Finally, the cement thickening layer 9, waterproof primer 10, elastic particle layer 11, PU elastic layer 12 and polyurethane surface layer 13 are laid on the metal base plate 3 in sequence, ensuring that the upper surface of the polyurethane surface layer 13 is at the same level as the upper surface of the first metal drainage ditch 4 and the second metal drainage ditch 5.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
