Description

Technical Field

[0001] This utility model relates to the field of running tracks, and in particular to a prefabricated polyurethane running track. Background Technology

[0002] Running tracks, as a venue for people's sports and leisure, have good shock absorption properties. Existing running tracks are laid with roll materials, which are generally composed of a base layer, an adhesive layer, an elastic layer, and a wear-resistant layer. When people exercise on the running track, it can effectively absorb the impact generated by the track, avoiding excessive impact on the ankles and knees, thus protecting human health. However, the existing technology of running tracks overemphasizes its shock absorption performance, resulting in the track being too soft and having poor rebound performance. People who step on the track lack rebound feedback, which will consume extra energy, easily feel fatigued, and increase the risk of sprains, thus resulting in a poor experience.

The second polyurethane elastic layer is bonded to the upper surface of the treatment layer. The first polyurethane elastic layer has the reinforcing layer, and the second polyurethane elastic layer is provided on the upper surface of the reinforcing layer.

[0011] As a further embodiment of this invention, the base layer is made of cement or asphalt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an elastic layer on the polyurethane running track, with a reinforcing layer embedded inside the elastic layer having both toughness and hardness, and using double-layer polyurethane to wrap the reinforcing layer, and then laying a wear-resistant surface layer on the reinforcing layer, the running track can be more resilient and elastic while having a certain degree of shock absorption, because the reinforcing layer can also provide a certain degree of rebound feedback.

[0023] Please see Figs. 1-2 In this embodiment of the present invention, a prefabricated polyurethane running track includes: a base layer 1, a treatment layer 2, an elastic layer 3, and a surface layer 4. The upper surface of the base layer 1 is covered with the treatment layer 2 to enhance adhesion. The upper surface of the treatment layer 2 is provided with the elastic layer 3, and the upper surface of the elastic layer 3 is provided with the surface layer 4. The elastic layer 3 includes a first polyurethane elastic layer 31, a reinforcing layer 33, and a second polyurethane elastic layer 32. The second polyurethane elastic layer 32 is adhered to the upper surface of the treatment layer 2.

[0024] Layer 31 has a reinforcing layer 33, and a second polyurethane elastic layer 32 is provided on the upper surface of the reinforcing layer 33. Specifically, the connection method between the layers includes, but is not limited to, adhesive methods. A surface layer 4 is laid on the upper surface of the second polyurethane elastic layer 32. The surface layer 4 can be made of wear-resistant rubber and has anti-slip texture on its surface. The treatment layer 2 is used to form a dense protective film on the base layer 1, which can improve the adhesion between the base layer 1 and the adhesive layer. The treatment layer 2 can be a primer. Working principle of this embodiment: By setting an elastic layer 3 on the polyurethane track, the elastic layer 3 has a reinforcing layer 33 with toughness and hardness embedded inside. The reinforcing layer 33 is wrapped with double-layer polyurethane, and the wear-resistant surface layer 4 is laid on the reinforcing layer 33. The track has a certain degree of shock absorption, and the reinforcing layer 33 can also provide a certain degree of rebound feedback, making the track more resilient and solving the problem of the track being too soft, so as to provide people with a good experience when walking or running on the track.

[0025] Further as Figs. 1-2 As shown, in this embodiment of the invention, the thickness of the first polyurethane elastic layer 31 is not less than the thickness of the second polyurethane elastic layer 32. The first polyurethane elastic layer 31 has stronger cushioning performance than the second polyurethane elastic layer 32. When people step on the track, the pressure is transmitted to the track, and the second polyurethane elastic layer 32 provides a certain cushioning effect and reduces the pressure. The reinforcing layer 33 has sufficient toughness to provide support and rebound, providing a comfortable exercise experience. The sandwich structure design makes the elastic layer 3 more resilient.

[0026] Further as Figs. 1-2 As shown, in this embodiment of the invention, the thickness of the first polyurethane elastic layer 31 is 4 mm, and the thickness of the second polyurethane elastic layer 32 is 2 mm. The thicker the polyurethane elastic layer, the better its shock absorption performance. The optimal thickness is achieved when the first polyurethane elastic layer 31 is 4 mm and the second polyurethane elastic layer 32 is 2 mm. Combined with the good toughness and elasticity of the reinforcing layer 33, the first polyurethane elastic layer 31 can absorb high-frequency impacts, such as the moment the foot strikes the ground, while the second polyurethane elastic layer 32 can alleviate low-frequency vibrations, such as continuous pressure during running.

[0027] Further as Figs. 1-3 As shown, in the embodiments of this utility model, the reinforcing layer 33 is made of carbon fiber nylon sheet or glass fiber rubber sheet. The hardness of the reinforcing layer 33 is higher than that of the polyurethane elastic layer. The combination of the reinforcing layer 33 and the polyurethane elastic layer makes the performance of the elastic layer 3 more comprehensive. On the one hand, it has the shock absorption of the polyurethane elastic layer, and on the other hand, it has the toughness and rigidity of the reinforcing layer 33. It has impact resistance and can also provide force feedback, so that people feel a firm and elastic feel when stepping on the track. When running or walking, the track has strong force feedback and a certain degree of shock absorption.

[0028] Specifically, the carbon fiber nylon sheet contains 15%-30% carbon fiber, providing sufficient bending strength for installation in high-torsional-resistance areas such as track curves. The fiberglass rubber sheet possesses a certain degree of toughness and excellent impact resistance, effectively absorbing impact and providing support. It can be used to lay the entire length of the track. Polyurethane elastic layers are installed at both ends of the fiberglass rubber sheet as elastic layers 3, giving the track a certain degree of resilience and preventing the track from being too soft, thus avoiding excessive physical exertion.

[0029] Further as Figs. 1-2 As shown in the embodiment of this utility model, the thickness of the surface layer 4 is 2-5mm, the material of the surface layer 4 is wear-resistant rubber, and the upper surface of the surface layer 4 is provided with anti-slip texture. Specifically, the anti-slip texture includes, but is not limited to, granular and self-textured textures.

[0030] In another embodiment of this utility model, an anti-slip layer is laid on the upper surface of the surface layer 4. The anti-slip layer and the surface layer 4 can be integrally connected, which can effectively prevent stress concentration in the track during use and improve the peel strength during use.

[0031] Further as Figs. 1-2 As shown, in an embodiment of this utility model, the upper end of the surface layer 4 is provided with lines for drawing boundaries or dividing lines, and the width of the lines is 5cm.

[0032] Further as Figs. 1-2 As shown, in an embodiment of this utility model, the base layer 1 is made of cement or asphalt.

[0033] It will be apparent to those skilled in the art that this invention 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 essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
