Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyurea running track technology, and in particular to a corrugated polyurea running track structure. Background Art
[0002] Polyurea running tracks are sports tracks paved with polyurea materials, commonly used in outdoor sports fields such as athletic fields and school playgrounds. Polyurea is a two-component reactive coating formed by the reaction of isocyanate and amine resin components. Due to its wear resistance, aging resistance, slip resistance, and weather resistance, polyurea has become an ideal surface material for running tracks. The main characteristics of polyurea running tracks include: High elasticity and cushioning: Polyurea achieves a balance between hardness and elasticity, helping to reduce the impact on athletes' joints during running and reducing sports injuries. Weather resistance: Polyurea has good UV resistance and oxidation resistance, allowing for prolonged outdoor exposure without easily aging or cracking, suitable for various weather conditions. Wear resistance and durability: The wear-resistant surface of polyurea running tracks is suitable for high-frequency use, effectively extending the track's lifespan. Environmental friendliness: Polyurea does not produce harmful solvent evaporation during the spraying process, resulting in less environmental pollution and making it more environmentally friendly than traditional polyurethane running tracks. Rapid curing: Polyurea materials cure quickly, typically within seconds to tens of seconds, accelerating the construction process. Due to these characteristics, polyurea running tracks are gradually becoming a replacement for traditional synthetic running tracks (such as EPDM and polyurethane tracks), especially favored in projects with high requirements for durability and environmental friendliness.
[0003] Existing polyurea running track structures typically feature relatively flat surfaces to reduce construction difficulty and improve temperature and comfort when athletes walk on them. However, these flat polyurea running track structures do not fully utilize the uneven surface design of existing sports equipment anti-slip structures, leaving significant room for improvement in the anti-slip performance and grip of polyester running track structures. Utility Model Content
[0004] Therefore, it is necessary to provide a corrugated polyurea running track structure to address the technical problem of insufficient anti-slip performance of existing polyester running track structures.
[0005] A corrugated polyurea running track structure includes a base layer, a buffer layer, a protective layer, and a corrugated surface layer. The base layer serves as the bottom layer of the running track structure and is laid on a pre-set surface. The buffer layer is disposed on the top side surface of the base layer. The protective layer is disposed on the top side surface of the buffer layer. The corrugated surface layer is disposed on the top side surface of the protective layer.
[0006] The corrugated polyurea runway structure also includes an intermediate support layer with a corrugated top surface. The intermediate support layer is located between the buffer layer and the protective layer, so that when the protective layer and the corrugated surface layer are sequentially stacked on the top surface of the intermediate support layer, a corrugated structure can be formed. The corrugated surface layer is a polyurea coating applied to the top surface of the protective layer, thereby forming the main body of the corrugated surface layer.
[0007] The surface wave pattern layer has several wave peaks and several wave troughs arranged alternately, thus forming a wave-shaped structure of the surface wave pattern layer.
[0008] In one embodiment, the crest height is set to 2-4 mm and the trough spacing is set to 8-12 mm.
[0009] In one embodiment, each of the aforementioned troughs is configured as a drainage channel structure with depth gradually increasing from the middle to both ends.
[0010] In one embodiment, the depth of the middle part of the trough is set to 1-2 mm, and the depth of both ends of the trough is set to 3-4 mm.
[0011] In one embodiment, the aforementioned surface corrugated layer is provided with a plurality of first drainage holes, which are evenly distributed on the surface of the surface corrugated layer and connect the two sides of the surface corrugated layer.
[0012] In one embodiment, the protective layer is provided with a plurality of second drainage holes, each of which corresponds to a plurality of first drainage holes and is distributed on the surface of the protective layer, and each second drainage hole connects to both sides of the protective layer.
[0013] In one embodiment, the base layer, buffer layer and intermediate support layer are all configured as porous structures.
[0014] In one embodiment, the aforementioned intermediate support layer adopts a polyurethane-based permeable structure, thereby promoting water penetration while ensuring support performance.
[0015] In one embodiment, the porosity of the aforementioned intermediate support layer is set to 15-25%, and the thickness is set to 5-10 mm.
[0016] In one embodiment, the aforementioned buffer layer is made of a high-molecular-weight permeable material, thereby accelerating water drainage while ensuring the absorption capacity of impact force.
[0017] In one embodiment, the porosity of the buffer layer is set to 15-30%, and the thickness is set to 10-15 mm.
[0018] In one embodiment, the aforementioned base layer is made of permeable concrete, which provides structural support for the overall runway structure while forming permeable channels.
[0019] In one embodiment, the porosity of the base layer is set to 15-25%, and the thickness is set to 50-100 mm.
[0020] In one embodiment, the protective layer is made by coating the top surface of the intermediate support layer with a two-component polyurea coating mixed with wear-resistant filler.
[0021] In one embodiment, the thickness of the protective layer is set to 1.5-3 mm.
[0022] The aforementioned corrugated polyurea running track structure provides excellent anti-slip properties, friction, and visual appeal by setting a corrugated surface layer on the top surface of the protective layer. The corrugated polyurea running track structure also includes an intermediate support layer with a corrugated top surface, positioned between the buffer layer and the protective layer. This allows the protective layer and the corrugated surface layer to form a corrugated structure when sequentially stacked on the top surface of the intermediate support layer. The corrugated surface layer is a polyurea coating applied to the top surface of the protective layer, forming the main body of the corrugated surface layer. The corrugated surface layer features alternating peaks and troughs, creating a wave-like structure. This improves the compatibility between the running track surface and the uneven surfaces of existing sports equipment anti-slip structures, such as spikes or anti-slip protrusions on the soles of spiked shoes, thereby enhancing the anti-slip properties and grip of the running track structure and preventing athletes from slipping during starts, acceleration, and turns. Simultaneously, the flexibility of the polyurea coating effectively improves the elasticity of the running track structure, thus enhancing comfort. Attached Figure Description

[0030] Please see Figure 1 This utility model discloses a corrugated polyurea running track structure, which includes a base layer 100, a buffer layer 200, a protective layer 300, and a surface corrugated layer 400. The base layer 100 serves as the bottom layer of the running track structure and is laid on a pre-set surface. The buffer layer 200 is disposed on the top surface of the base layer 100 and serves as a buffer and shock absorption layer to reduce the impact force during the athlete's running. The protective layer 300 is disposed on the top surface of the buffer layer 200 and enhances the overall durability of the running track structure. The surface corrugated layer 400 is disposed on the top surface of the protective layer 300 to provide good anti-slip properties, friction, and visual effect. Specifically, the corrugated polyurea running track structure also includes an intermediate support layer 500 with a corrugated top surface. The intermediate support layer 500 is positioned between the buffer layer 200 and the protective layer 300, so that when the protective layer 300 and the corrugated surface layer 400 are sequentially stacked on the top surface of the intermediate support layer 500, a corrugated structure can be formed. Based on this, the corrugated surface layer 400 is a polyurea coating applied to the top surface of the protective layer 300, thus forming the main body of the corrugated surface layer 400. More specifically, the corrugated surface layer 400 has several alternating peaks 410 and several troughs 420, thus forming a corrugated structure. This improves the anti-slip and grip properties of the running track surface, preventing athletes from slipping during acceleration and turns. At the same time, the flexibility of the polyurea coating can also effectively improve the elasticity of the running track structure, thereby enhancing comfort. In one embodiment, the height of the crest 410 is set to 2-4 mm, and the spacing of the troughs 420 is set to 8-12 mm, thereby ensuring a uniform distribution of grip and friction when the athlete is running.
[0031] Furthermore, each trough 420 is configured as a drainage channel structure with its depth gradually increasing from the middle to both ends. Thus, when water accumulates on the runway structure surface, rainwater flows into the trough 420, and simultaneously flows from the middle to both ends of the trough 420, then is quickly discharged through the ends, thereby preventing water accumulation on the runway structure surface. In one embodiment, the depth of the middle of the trough 420 is set to 1-2 mm, and the depth of the two ends of the trough 420 is set to 3-4 mm, thereby improving the drainage capacity of the runway structure surface while ensuring its surface support performance.
[0032] Furthermore, the surface corrugated layer 400 is provided with a plurality of first drainage holes a, which are evenly distributed on the surface of the surface corrugated layer 400 and connect the two sides of the surface corrugated layer 400. Thus, rainwater on the surface of the surface corrugated layer 400 can seep into the bottom side of the surface corrugated layer 400 through the plurality of first drainage holes a, so as to further accelerate the drainage efficiency of the runway structure surface.
[0033] Furthermore, the protective layer 300 is provided with a plurality of second drainage holes b, each corresponding one-to-one with a plurality of first drainage holes a and distributed on the surface of the protective layer 300. Each second drainage hole b connects to both sides of the protective layer 300, thereby allowing rainwater that seeps in from the surface corrugated layer 400 to seep into the bottom side of the protective layer 300 through the plurality of second drainage holes b. Specifically, the base layer 100, the buffer layer 200, and the intermediate support layer 500 are all configured with a porous structure, so that rainwater that seeps in from the protective layer 300 can sequentially seep into the paving surface through the intermediate support layer 500, the buffer layer 200, and the base layer 100, that is, into the ground, thereby achieving rapid drainage of the runway structure.
[0034] Furthermore, the intermediate support layer 500 adopts a polyurethane-based permeable structure to promote water permeation while ensuring support performance. In one embodiment, the porosity of the intermediate support layer 500 is set to 15-25%, and the thickness is set to 5-10 mm, thereby maintaining the support capacity of the intermediate support layer 500 while ensuring water permeability.
[0035] Furthermore, the buffer layer 200 is made of a high-molecular permeable material to accelerate water drainage while ensuring impact absorption capacity. In one embodiment, the porosity of the buffer layer 200 is set to 15-30%, and the thickness is set to 10-15 mm, thereby maintaining the buffering performance of the buffer layer while ensuring drainage capacity.
[0036] Furthermore, the base layer 100 is made of permeable concrete, which provides structural support for the overall runway structure while forming permeable channels. In one embodiment, the porosity of the base layer 100 is set to 15-25%, and the thickness is set to 50-100 mm.
[0037] Furthermore, the protective layer 300 is a two-component polyurea coating mixed with wear-resistant filler, applied to the top surface of the intermediate support layer 500. In one embodiment, the thickness of the protective layer 300 is set to 1.5-3mm, thereby providing the overall runway structure with high wear resistance, weather resistance and anti-aging properties, protecting the intermediate support layer 500 and the buffer layer 200, and thus increasing the overall service life of the runway structure.
[0038] In summary, the corrugated polyurea running track structure disclosed in this utility model provides excellent anti-slip properties, friction, and visual appeal by setting a corrugated surface layer on the top side surface of the protective layer. The corrugated polyurea running track structure also includes an intermediate support layer with a corrugated top surface, positioned between the buffer layer and the protective layer. This allows the protective layer and the corrugated surface layer to form a corrugated structure when sequentially stacked on the top side surface of the intermediate support layer. Based on this, the corrugated surface layer is a polyurea coating applied to the top side surface of the protective layer, forming the main body of the corrugated surface layer. The corrugated surface layer has alternating peaks and troughs, forming a wave-like structure. This improves the compatibility between the running track structure surface and the uneven surfaces of existing sports equipment anti-slip structures, such as spikes or anti-slip protrusions on the soles of spiked shoes, thereby enhancing the anti-slip properties and grip of the running track structure and preventing athletes from slipping during start-up, acceleration, and turning. Simultaneously, the flexibility of the polyurea coating effectively improves the elasticity of the running track structure, thus enhancing comfort.
[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
