Description

Technical Field

[0001] The present application relates to the technical field of basketball court structures, and in particular to silicon PU basketball court structures. Background Art

[0002] Basketball is a sport full of vitality and passion. Its origin can be traced back to the United States in the late 19th century. Initially, basketball was just an indoor sport, but with the passage of time, it has gradually developed into a global sport. As an important infrastructure for basketball, the development of basketball courts is closely related to the popularization and promotion of basketball. With the gradual popularization of basketball and the improvement of competitive level, the demand for basketball courts has also increased, which has promoted the construction and improvement of basketball courts. With the advancement of science and technology, the materials, structures and functions of basketball courts are also constantly improving. Most modern basketball courts use advanced materials and technologies, such as high-grade plastics, elastic Cushioning, etc., to improve the performance and comfort of the venue. Appropriate elasticity and shock absorption can reduce the burden on athletes' feet and joints and reduce fatigue during exercise, which helps to improve athletes' physical energy consumption capacity and the durability of the game. A basketball court with a higher degree of comfort can provide a better sports experience, allowing athletes to be more focused and more efficient. Poor venue elasticity will cause players to feel uncomfortable and tired during running, jumping, turning and other actions, increasing the risk of injuries to players' knees, ankles and other joints. At the same time, the rebound force of the basketball will be affected, resulting in irregular bouncing of the basketball, affecting players' shooting and ball control, and reducing the viewing of the game.

[0003] In order to solve the problem that the poor elasticity of the court raised in the related art will cause players to feel uncomfortable and tired during running, jumping and turning, increase the risk of injuries to players' knees, ankles and other joints, and the rebound force of the basketball will be affected, resulting in irregular bounce of the basketball, affecting the players' shooting and ball control, and reducing the viewing experience of the game, the present application provides a silicon PU basketball court structure.

[0004] Specifically, the silicon PU basketball court structure includes a base surface layer, a waterproof layer, an elastic layer, a reinforcement layer and a surface layer, wherein the elastic layer includes at least two layers of fine-grained elastic layers and one layer of coarse-grained elastic layer, and the surface layer is composed of a mixture of granular matter and silicon PU material;

[0005] Among them, the density of elastic particles in the fine-grained elastic layer is greater than that in the coarse-grained elastic layer, and the fine-grained elastic layer is arranged on the upper end of the coarse-grained elastic layer, so that the silicon PU basketball court structure is hard on the top and soft on the bottom, which is used to improve the rebound rate of the basketball after contacting the basketball court surface.

[0006] Furthermore, the volume of the coarse-grained elastic material in the coarse-grained elastic layer is greater than the volume of the fine-grained elastic material in the fine-grained elastic layer.

[0007] Furthermore, the waterproof layer is located on the lower surface of the elastic layer, and the base surface layer is located on the lower surface of the waterproof layer.

[0008] Furthermore, the waterproof layer includes a waterproof primer and a primer.

[0009] Furthermore, the foundation surface layer is formed by casting cement concrete, and the upper surface of the foundation surface layer is rough.

[0010] Furthermore, the thickness of the cement concrete poured on the foundation surface layer is not less than 100 mm.

[0011] Furthermore, the standard value of the compressive strength of the concrete of the foundation surface layer is not less than 20Mpa.

[0012] Furthermore, the reinforcement layer is located on the upper surface of the elastic layer, and the reinforcement layer is made of silicone-modified polyurethane material.

[0013] Furthermore, the surface layer is located on the upper surface of the reinforcement layer.

[0014] Furthermore, the surface layer is formed by mixing particles and silicon PU material.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the silicon PU basketball court structure, the thickness of the concrete foundation surface layer is set to be no less than 100mm, so that the thicker foundation surface layer can provide a higher bearing capacity to disperse the impact force generated by athletes during competitions and training, thereby reducing ground deformation and cracking, and further reducing the occurrence of safety hazards;

[0017] 2. In the silicon PU basketball court structure, a waterproof layer is arranged on the upper surface of the base surface layer, and a waterproof primer and a primer are used to increase the overall waterproof performance of the silicon PU basketball court structure, thereby avoiding the erosion of the inside of the silicon PU basketball court structure by water penetration and increasing the service life of the silicon PU basketball court structure;

[0018] 3. In the silicon PU basketball court structure, by setting the fine-grained elastic layer on the upper end of the coarse-grained elastic layer, and setting at least two layers of fine-grained elastic layers and one layer of coarse-grained elastic layer, it is ensured that the elastic layer has sufficient elasticity, so that when the athlete is exercising, the court is subjected to greater force, and the coarse-grained elastic layer will cushion the athlete's jumping by deformation.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0025] In addition, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure schematically placed in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the change of the orientation of the structure.

[0026] See also Figure 1 to Figure 2, an embodiment of the present application provides a silicon PU basketball court structure, including a base surface layer 5, a waterproof layer 4, an elastic layer 3, a reinforcement layer 2 and a surface layer 1, the elastic layer 3 includes at least two layers of fine-grained elastic layers 301 and one layer of coarse-grained elastic layer 302, the gap between the two layers of fine-grained elastic layers 301 can be filled with air to form a good airtight layer, thereby improving the overall stability of the silicon PU basketball court structure and extending the service life of the court, the fine-grained elastic layer 301 is composed of a mixture of fine-grained elastic material and polyurethane material, the coarse-grained elastic layer 302 is composed of a mixture of coarse-grained elastic material and polyurethane material, the particle size of the fine-grained elastic material is smaller than the particle size of the coarse-grained elastic material, and the distribution density of the particles of the fine-grained elastic material in the fine-grained elastic layer 301 is smaller than the distribution density of the particles of the coarse-grained elastic material in the coarse-grained elastic layer 302, so as to enable the elastic layer 3 to better disperse the pressure exerted on the court by the athlete's feet and body, thereby providing a better buffering effect;

[0027] Among them, the density of elastic particles in the fine-grained elastic layer 301 is greater than that in the coarse-grained elastic layer 302, and the fine-grained elastic layer 301 is arranged on the upper end of the coarse-grained elastic layer 302, so that the silicon PU basketball court structure is hard on the top and soft on the bottom, which is used to improve the rebound rate of the basketball after contacting the basketball court surface.

[0028] The volume of the coarse-grained elastic material in the coarse-grained elastic layer 302 is greater than the volume of the fine-grained elastic material in the fine-grained elastic layer 301, so that the coarse-grained elastic material has greater elasticity and cushioning performance than the fine-grained elastic material, thereby improving the absorption and dispersion of the impact force generated by athletes during exercise, and further reducing the risk of sports injuries to athletes.

[0029] The waterproof layer 4 is located on the lower surface of the elastic layer 3. The waterproof layer 4 includes a waterproof primer and a primer. The waterproof primer penetrates into the base surface layer 5 and forms a closed isolation membrane to isolate ground water vapor. The base surface layer 5 is located on the lower surface of the waterproof layer 4.

[0030] The base surface layer 5 is formed by casting cement concrete. The upper surface of the base surface layer 5 is rough. The rough surface of the base surface layer 5 provides a larger contact area, so that the elastic layer 3 and the base surface layer are more firmly bonded, and the adhesion is improved to prevent the elastic layer 3 from peeling off or bubbles.

[0031] The thickness of the cement concrete poured for the foundation surface layer 5 is not less than 100mm, and the standard value of the compressive strength of the concrete for the foundation surface layer 5 is not less than 20Mpa. By setting the pouring thickness of the cement concrete to be at least 100mm and having a compressive strength of at least 20Mpa, the foundation surface layer 5 has sufficient bearing capacity to avoid breakage of the foundation surface layer 5 during use.

[0032] The reinforcing layer 2 is located on the upper surface of the elastic layer 3. The reinforcing layer 2 is made of silicone-modified polyurethane material. Due to the characteristics of the silicone-modified polyurethane material being hard on the top and soft on the bottom, the hard surface layer can retain sufficient rebound support for the basketball to ensure that the ball can bounce back after contacting the court.

[0033] The surface layer 1 is located on the upper surface of the reinforcement layer 2. The surface layer 1 is composed of a mixture of particles and silicon PU materials. The particles are preferably rubber particles. By mixing the rubber particles with the silicon PU material, the surface layer in the silicon PU basketball court structure is provided with flatness, wear resistance, non-slip, UV resistance and weather resistance. In the present application, the mixing ratio of the particles and the silicon PU material in the surface layer 1 can be mixed in a conventional ratio, such as the mass proportion of the particles is 10%-40%.

[0034] In the present application, the distribution density of particles in the surface layer 1 is less than the distribution density of elastic particles in the elastic layer 3. The thickness of the surface layer 1 composed of a mixture of particles and silicon PU material is less than the coarse-grained elastic layer 302 and the fine-grained elastic layer 301. By setting a thicker elastic layer 3, the silicon PU basketball court structure has sufficient elasticity. By setting the thickness of the surface layer 1 to be thinner than the coarse-grained elastic layer 302 and the fine-grained elastic layer 301, the rebound rate of the basketball after contacting the upper surface of the surface layer 1 is increased, thereby improving the athlete's sports experience.

[0035] This application has at least one of the following advantages:

[0036] (1) The thickness of the cement concrete foundation surface layer is at least 100 mm, and the standard value of the compressive strength of the foundation surface layer is not less than 20 MPa, which can make the foundation surface layer have a high bearing capacity to absorb and disperse the impact force generated by athletes during exercise;

[0037] (2) By setting a waterproof layer between the base surface layer and the elastic layer, the waterproof primer is used to penetrate into the base surface layer and form a closed isolation membrane in the base surface layer, thereby avoiding the erosion of the elastic layer by water vapor and preventing the elastic layer from peeling off or generating bubbles due to water infiltration, thereby improving the stability and service life of the silicon PU basketball court structure;

[0038] (3) By setting up at least two layers of fine-grained elastic layers and one layer of coarse-grained elastic layer, when the silicon PU basketball court structure is subjected to a large force, the coarse-grained elastic layer will cushion the athlete's jumping by deforming. When the ball touches the ground, the force area of ​​the silicon PU basketball court structure is small, so that the softer coarse-grained elastic layer at the bottom does not deform, and the harder fine-grained elastic layer at the top has bounced the ball, thereby ensuring the rebound rate of the ball.

[0039] The silicon PU basketball court structure provided by the implementation method of the present application is introduced in detail above, and the principle and implementation method of the present application are explained by using specific examples. The above description is only used to help understand the method and core mechanism of the present application; at the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific embodiments and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
