Description

Technical Field

[0001] This utility model relates to the field of sports field roll material technology, and in particular to a prefabricated sports field roll material. Background Technology

[0002] Precast sports field rolls are a high-performance material designed specifically for sports venues. They are manufactured using a factory prefabrication process, are slip-resistant and wear-resistant, made of environmentally friendly and non-toxic materials, and are easy to install. They can be used immediately after installation and can quickly create professional-standard sports fields, providing athletes with a safe and comfortable sports experience.

[0003] Prefabricated sports court rolls can be directly unrolled and laid after arriving on site, eliminating the need for complex on-site mixing and blending processes required for traditional sports court materials. This significantly shortens the construction period, hence the need for prefabricated sports court rolls. However, traditional prefabricated sports court rolls have poor cushioning and impact resistance. Poor cushioning and impact resistance means that the sports court rolls cannot effectively absorb the impact force generated by athletes during exercise, causing athletes' joints, knees, ankles, and other parts to bear greater pressure. Long-term exercise on such surfaces can easily lead to sports injuries such as joint wear and tear and muscle strains. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A prefabricated sports field roll includes an original running track base layer, an asphalt base layer installed on top of the original running track base layer, a waterproof isolation layer fixed on top of the asphalt base layer, a buffer component on top of the waterproof isolation layer, an impact-resistant component on top of the buffer component, a surface protective layer on top of the impact-resistant component, and embedded reinforcing ribs embedded in the inner wall of the surface protective layer.

[0008] As a preferred embodiment of the prefabricated sports field roll material of this utility model, the high-elasticity intermediate layer is a prepolymer polyurethane poured on site, and the top of the high-elasticity intermediate layer and the bottom of the bottom layer are fused together by heating.

[0009] As a preferred embodiment of the prefabricated sports field roll material of this utility model, the bottom layer material is a polyester fiber cloth material used to prevent the roll material from deforming and cracking, and the bottom layer is hot-melt bonded to the elastic layer.

[0010] As a preferred embodiment of the prefabricated sports field roll material of this utility model, the elastic layer is made of composite elastomer material and has a honeycomb design.

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1: Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a prefabricated sports field roll material, including an original running track base 1, an asphalt base 2 installed on the top of the original running track base 1, a waterproof isolation layer 3 fixed on the top of the asphalt base 2, a buffer component 4 provided on the top of the waterproof isolation layer 3, an impact-resistant component 5 provided on the top of the buffer component 4, a surface protective layer 6 provided on the top of the impact-resistant component 5, and a pre-embedded reinforcing rib 7 embedded in the inner wall of the surface protective layer 6.

[0024] The original track base layer 1 serves as the foundational support structure for the entire sports field roll material, providing a stable load-bearing platform for the upper components and ensuring the stability of the entire sports field structure. The asphalt base layer 2 is laid on top of the original track base layer 1, further leveling and strengthening the base layer, providing a more uniform and stable construction surface for the upper structure such as the waterproof isolation layer 3, and enhancing the overall performance of the base layer. The waterproof isolation layer 3 is made of polyurethane waterproof coating, which isolates groundwater vapor, prevents the roll material from swelling or delaminating due to moisture, and can also buffer minor deformations of the base layer, protecting the upper structure from the effects of groundwater vapor and base layer deformation. The pre-embedded reinforcing ribs 7 are embedded in the inner wall of the surface protective layer 6, improving the tensile strength of the roll material edges, preventing the roll material edges from curling and cracking, reducing stress concentration at the joints, and enhancing the stability of the roll material edges.

[0025] The buffer assembly 4 includes an EPDM rubber granule layer 41 installed on top of the waterproof isolation layer 3, and a highly elastic intermediate layer 42 is fixed on top of the EPDM rubber granule layer 41.

[0026] The EPDM rubber granule layer 41 is made of material with a particle size of 3-5mm, which facilitates the absorption of impact energy. Through material deformation, it reduces the direct force on the upper structure, thus achieving a buffering and shock-absorbing effect. The high-elasticity intermediate layer 42 is prepolymer polyurethane cast on-site, which further disperses the impact force and enhances the buffering performance of the buffer component 4. Its top and bottom layers 51 are fused together by heating to ensure a tight connection. It should be noted that the EPDM rubber granule layer 41 is ethylene propylene diene monomer (EPDM). EPDM has a stable molecular structure, does not contain unsaturated bonds, and is difficult to be damaged by ultraviolet light.

[0027] The impact-resistant component 5 includes a bottom layer 51 disposed on top of a highly elastic intermediate layer 42, an elastic layer 52 fixed on top of the bottom layer 51, and a top layer 53 disposed on top of the elastic layer 52.

[0028] The bottom layer 51 is used to prevent the roll material from deforming and cracking, and to enhance the tear resistance of the roll material. It is thermally melted and bonded with the elastic layer 52 to provide a stable base layer support for the elastic layer 52. The elastic layer 52 absorbs impact energy by deforming its geometric structure, and its impact resistance is improved compared with the planar structure. It is the core part of the impact-resistant component 5. The surface layer 53 adopts a thick silicone PU coating design, which works in synergy with the elastic layer 52 to improve impact resistance. Its top is connected to the surface protective layer 6 by an adhesive, providing a good adhesion base for the surface protective layer 6.

[0029] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the waterproof isolation layer 3 is made of polyurethane waterproof coating, which is used to isolate groundwater vapor and prevent the roll material from getting damp, swelling, or delaminating.

[0031] The waterproof isolation layer 3, formed by using polyurethane waterproof coating, forms a continuous elastic membrane that effectively prevents the intrusion of groundwater vapor, providing a dry and stable environment for the upper structure.

[0032] Specifically, the EPDM rubber particle layer 41 is made of EPDM rubber particles with a particle size of 3-5mm.

[0033] During the use of the court, athletes' movements, such as running, jumping, and sudden stops, will generate a large impact on the ground. The EPDM rubber granule layer 41 is made of EPDM rubber granules with a particle size of 3-5mm. There are certain gaps and elasticity between these granules. When subjected to impact, the rubber granules will deform and absorb and disperse the impact energy through their own elastic deformation, thereby reducing the direct impact of the impact on the underlying structure and base layer, reducing the risk of damage to the entire court structure, and extending the service life of the court.

[0034] Specifically, the high-elasticity intermediate layer 42 is a prepolymer polyurethane cast on-site, and the top of the high-elasticity intermediate layer 42 and the bottom of the bottom layer 51 are fused together by heating.

[0035] When an impact force is transmitted to this layer, it can further disperse the impact force to a larger area through its own elastic deformation, reduce local stress, enhance the impact resistance of the entire court roll, and ensure that the court can maintain stable and good performance under high-frequency use.

[0036] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, the bottom layer 51 is made of polyester fiber cloth material used to prevent the roll from deforming and cracking, and the bottom layer 51 is hot-melt bonded to the elastic layer 52.

[0038] The bottom layer 51 can effectively resist external forces. When the court roll is subjected to tensile, compressive or other stresses, it prevents the roll from deforming and cracking, maintains the integrity of the roll structure, and ensures the flatness and stability of the court surface. At the same time, the bottom layer 51 and the elastic layer 52 are hot-melt bonded together, which enhances the bonding force between the layers and avoids structural damage caused by the separation of the layers.

[0039] Specifically, the elastic layer 52 is made of a composite elastomer material and has a honeycomb shape.

[0040] When subjected to impact, the honeycomb wall can undergo elastic deformation, dispersing the impact force in all directions. At the same time, the cavities inside the honeycomb structure can act as a buffer, further reducing the impact of the impact force on the underlying structure. Moreover, the honeycomb design can reduce the weight of the elastic layer 52 and lower material costs while ensuring impact resistance.

[0041] Specifically, the surface layer 53 adopts a thick silicone PU coating design, and the top of the surface layer 53 is connected to the surface protective layer 6 by an adhesive.

[0042] The thick coating design enhances these properties, enabling it to resist friction, scratches, and erosion from natural factors such as UV rays and rain during daily use, thus extending the service life of the roll material. The adhesive ensures a tight bond between the surface layer 53 and the surface protective layer 6, forming a continuous protective system.

[0043] Specifically, the surface protective layer 6 is made of pure acrylic topcoat material used to improve wear resistance and slip resistance.

[0044] The surface protective layer 6 is used to improve abrasion resistance and slip resistance, protect the underlying roll material from UV rays, chemical corrosion, and wear and scratches during daily use, and extend the service life of the roll material.

[0045] When constructing prefabricated sports field rolls, the original track base layer 1 is used as the foundation, and an asphalt base layer 2 is installed on top of it. This layer further flattens and strengthens the base layer, providing a uniform and stable construction surface for subsequent construction. Next, a waterproof isolation layer 3 is fixed on the asphalt base layer 2. This layer is made of polyurethane waterproof coating, which can form a continuous elastic film, effectively isolating groundwater vapor, preventing the roll from swelling or delaminating due to moisture, and also buffering minor deformations of the base layer. Subsequently, a buffer component 4 is set on top of the waterproof isolation layer 3. First, an EPDM rubber particle layer 41 made of EPDM rubber particles with a particle size of 3-5mm is laid, which can absorb impact energy and play a buffering and shock-absorbing role. Then, prepolymer polyurethane is poured to form a highly elastic intermediate layer 42, which can further disperse the impact force and is in contact with the base layer. The bottom of layer 51 is heated and fused to ensure a tight connection. Then, an impact-resistant component 5 is installed on top of the high-elasticity intermediate layer 42. The bottom layer 51 is made of polyester fiber cloth to prevent the roll from deforming and cracking. It is heat-fused to the elastic layer 52. The elastic layer 52 is made of composite elastomer material and has a honeycomb design, which can absorb impact energy by structural deformation. The surface layer 53 has a thick silicone PU coating design, which works with the elastic layer 52 to improve impact resistance. Its top is connected to the surface protective layer 6 with adhesive. Finally, a surface protective layer 6 is set on top of the impact-resistant component 5. Its material is pure acrylic paint, which can improve wear resistance and anti-slip properties and protect the underlying structure. At the same time, embedded reinforcing ribs 7 are embedded in the inner wall of the surface protective layer 6 to improve the tensile strength of the roll edge and prevent edge cracking.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
