Description

Technical Field

[0001] This utility model relates to the field of composite flooring technology, specifically a novel environmentally friendly TPU and EVA composite sports floor that can be used on both sides. Background Technology

[0002] In the field of sports facilities, the performance of sports flooring is crucial. Traditional single-material sports flooring, such as pure wood flooring, while offering good elasticity and comfort and providing some cushioning protection for athletes, has poor moisture and insect resistance. In humid environments, wooden flooring is prone to warping and mold growth, not only affecting its appearance but also potentially altering surface friction, increasing the risk of slips and injuries for athletes. Furthermore, over long-term use, wooden flooring is susceptible to insect infestation, reducing its structural strength and shortening its lifespan.

[0003] Conventional composite flooring uses tongue-and-groove joints on both sides for splicing. However, with the increase of usage time and the influence of external factors, the joints at the front and back ends, as well as the left and right sides, will experience warping. This will cause unnecessary changes to the overall flatness of the installation structure. Moreover, the top layer of environmentally friendly wear-resistant material will wear out and the entire floorboard will need to be replaced.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a new type of environmentally friendly TPU and EVA composite sports floor that can be used on both sides. Summary of the Invention

[0005] The purpose of this invention is to provide a novel environmentally friendly TPU and EVA composite sports floor that can be used on both sides, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel environmentally friendly TPU and EVA composite sports floor that can be used on both sides, comprising a composite floor body and an assembly. The assembly is installed at one end of the composite floor body, and a splicing strip is horizontally inserted at the bottom of the composite floor body. A first tongue and groove is provided on one side surface of the composite floor body, and a second tongue and groove is provided on the side of the composite floor body away from the first tongue and groove. At the same time, a splicing slot is opened on the bottom surface of the composite floor body. A fixing hole is opened at the end of the composite floor body near the assembly, and a mating joint is opened on the side of the composite floor body away from the fixing hole. A connecting block is provided at the bottom edge of the end of the composite floor body near the assembly, and a connecting opening is opened at the bottom edge of the end of the composite floor body away from the mating joint.

[0007] Furthermore, the composite flooring body includes an environmentally friendly wear-resistant layer, a fiberglass layer, a densely woven fabric layer, an antibacterial and mildew-proof layer, and a buffer layer. The fiberglass layer is disposed adjacent to one side of the environmentally friendly wear-resistant layer, and the densely woven fabric layer is connected to the side of the fiberglass layer away from the environmentally friendly wear-resistant layer. The antibacterial and mildew-proof layer is connected to the side of the densely woven fabric layer away from the fiberglass layer, and the buffer layer is connected to the side of the antibacterial and mildew-proof layer away from the densely woven fabric layer.

[0008] Furthermore, the environmentally friendly wear-resistant layer is made of a mixture of TPU and EVA, and the environmentally friendly wear-resistant layer, glass fiber layer, densely woven fabric layer, antibacterial and mildew-proof layer and buffer layer are tightly fused together.

[0009] Furthermore, the assembly includes a connecting block, expansion bolts, and reinforcing ribs. Expansion bolts are horizontally inserted through both ends of the connecting block, and reinforcing ribs are installed at the ends of the expansion bolts that are close to the main body of the composite floor.

[0010] Furthermore, the internal surface structure of the fixed socket matches the external surface structure of the expansion bolt and the reinforcing rib, and the internal surface structure of the mating socket matches the external surface structure of the connecting block and one end of the expansion bolt.

[0011] Furthermore, the inner surface structure of the splicing slot matches the surface structure of one end of the splicing strip, and the splicing slots are equidistantly arranged and symmetrically opened on the bottom surface of the composite floor body.

[0012] Furthermore, the surface structures of the first tongue and groove and the second tongue and groove are matched with each other, and the first tongue and groove, the second tongue and groove and the composite floor body are integrated into one structure.

[0013] Furthermore, the inner surface structure of the connector matches the outer surface structure of the connector block, and both the connector and the connector block are integrally integrated with the main body of the composite floor.

[0014] This utility model provides a novel environmentally friendly TPU and EVA composite sports floor that can be used on both sides, and has the following beneficial effects: After the original environmentally friendly wear-resistant layer on the top surface is worn, the bottom surface of the entire composite floor body is flipped up to replace the structure, thereby realizing the use of the entire composite floor body on both sides. This not only increases the functionality of the double-sided floor, making it usable on both sides, but also increases its service life and reduces maintenance costs.

[0015] 1. This utility model, by providing fixing holes and docking slots at both ends of the composite flooring body, allows for the rapid splicing of composite flooring bodies. The assembly component, with its reinforcing ribs, is horizontally inserted into the fixing holes. Then, the expansion bolts at both ends of the connecting block, away from the reinforcing ribs, are horizontally inserted into the docking slot at one end of another composite flooring body. The detachable structure between the composite flooring body and the assembly component allows for selective use of the assembly component as needed, ensuring ease of use and flexibility. The expansion bolts ensure a strong and stable connection between the assembly component and the composite flooring body. The reinforcing ribs, located inside the composite flooring body, provide structural support, improving structural strength. Furthermore, the assembly component design prevents unnecessary warping at the joint between the front and rear ends of the two composite flooring bodies, ensuring a smooth and even structure after installation.

[0016] 2. This utility model, by providing splicing slots on the bottom surface of the composite flooring body, and using splicing strips in conjunction with them, allows the composite flooring body to be spliced ​​left and right using the first and second tongue-and-groove joints on both sides. The splicing slots at the bottom of the joints between the composite flooring bodies are then aligned, and the splicing strips are inserted. This method, on the one hand, assists in providing further structural connection and firmness to the assembled composite flooring body, preventing sliding and misalignment; on the other hand, it provides good structural support at the bottom of the assembled composite flooring body, preventing warping at the joints on both sides and ensuring the stability of the assembled structure. The assembled composite flooring body thus has sufficient stable support. Furthermore, the thickness of the environmentally friendly wear-resistant layer is greater than that of the antibacterial and mildew-proof layer, and the thickness of the cushioning layer is 3-10 times that of the environmentally friendly wear-resistant layer. This ensures that the entire composite flooring body has good structural cushioning, protecting users from significant injury if they fall on the surface of the composite flooring body.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0024] like Figures 1 to 5As shown, a novel environmentally friendly TPU and EVA composite sports floor that can be used on both sides includes a composite floor body 1 and an assembly 2. The assembly 2 is installed at one end of the composite floor body 1, and a splicing strip 3 is horizontally inserted into the bottom of the composite floor body 1. A first tongue and groove 4 is provided on one side surface of the composite floor body 1, and a second tongue and groove 5 is provided on the side of the composite floor body 1 away from the first tongue and groove 4. A splicing slot 6 is provided on the bottom surface of the composite floor body 1. A fixing hole 7 is provided at the end of the composite floor body 1 near the assembly 2, and a mating joint 8 is provided on the side of the composite floor body 1 away from the fixing hole 7. A connecting block 9 is provided on the bottom edge of the end of the composite floor body 1 near the assembly 2, and a connecting joint 10 is provided on the bottom edge of the end of the composite floor body 1 away from the mating joint 8. The assembly 2 includes a connecting block 201, an expansion bolt 202, and a reinforcing rib 203. The expansion bolts 202 are horizontally inserted through both ends of the connecting block 201, and the reinforcing rib 203 is installed at the end of the expansion bolt 202 closest to the composite floor body 1. The internal surface structure of the fixing hole 7 matches the external surface structure of the expansion bolt 202 and the reinforcing rib 203, and the internal surface structure of the mating socket 8 matches the external surface structure of one end of the connecting block 201 and the expansion bolt 202. By horizontally inserting the end of the assembly 2 with the reinforcing rib 203 into the interior of the fixing hole 7, and then using the ends of the expansion bolts 202 at both ends of the connecting block 201 away from the reinforcing rib 203 to be horizontally inserted into the mating socket 8 at one end of another set of composite floor bodies 1, the composite floor bodies 1 can be quickly spliced ​​together front and back.

[0025] like Figures 1 to 5As shown, the composite flooring body 1 includes an environmentally friendly wear-resistant layer 101, a fiberglass layer 102, a densely woven fabric layer 103, an antibacterial and mildew-resistant layer 104, and a cushioning layer 105. The fiberglass layer 102 is disposed adjacent to one side of the environmentally friendly wear-resistant layer 101, and the densely woven fabric layer 103 is connected to the side of the fiberglass layer 102 away from the environmentally friendly wear-resistant layer 101. The antibacterial and mildew-resistant layer 104 is connected to the side of the densely woven fabric layer 103 away from the fiberglass layer 102, and the cushioning layer 105 is connected to the side of the antibacterial and mildew-resistant layer 104 away from the densely woven fabric layer 103. The environmentally friendly wear-resistant layer 101 is made of a mixture of TPU and EVA materials, and the environmentally friendly wear-resistant layer 101, fiberglass layer 102, densely woven fabric layer 103, antibacterial and mildew-resistant layer 104, and cushioning layer 105 are tightly fused together. Next, the inner surface structure of the splicing slot 6 matches the surface structure of one end of the splicing strip 3, and the splicing slots 6 are equidistantly arranged and symmetrically opened on the bottom surface of the composite floor body 1. The surface structures of the first tongue and groove 4 and the second tongue and groove 5 match each other, and the first tongue and groove 4 and the second tongue and groove 5 are integrated with the composite floor body 1. The inner surface structure of the connecting port 10 matches the outer surface structure of the connecting block 9, and the connecting port 10 and the connecting block 9 are integrated with the composite floor body 1. After the composite floor body 1 is spliced ​​in the left and right direction using the first tongue and groove 4 and the second tongue and groove 5 on the left and right sides, the splicing slots 6 set at the bottom of the connection between the composite floor body 1 are aligned, and then the splicing strip 3 is inserted into them. Example

[0026] The bottom surface of the entire composite flooring can be sequentially provided with a densely woven fabric layer 103, a fiberglass layer 102, and an environmentally friendly wear-resistant layer 101. This structure allows the bottom surface of the entire composite flooring to be flipped up and replaced after the original top layer of environmentally friendly wear-resistant layer wears down. This enables the entire composite flooring to be used on both sides, increasing its functionality and lifespan while reducing maintenance costs.

[0027] In summary, as Figures 1 to 5 As shown, this new type of environmentally friendly TPU and EVA composite sports floor that can be used on both sides can be used in the following ways: First, when it is necessary to structurally splice the main body 1 of the composite floor in the front and back directions, you can choose whether to use the assembly 2. If the assembly 2 is used, you only need to horizontally insert the end of the connecting block 201 with the expansion bolts 202 at both ends and the reinforcing ribs 203 into the fixed insertion hole 7. Then, the docking insertion port 8 at one end of the other composite floor main body 1 is structurally inserted into the other end of the assembly 2. During this process, the connecting block 9 at the bottom of one end of the composite floor main body 1 is spliced ​​into the connecting port 10 at the bottom of one end of the other composite floor main body 1 to ensure the structural stability of the joint.

[0028] If it is necessary to structurally splice the composite floor body 1 on the left and right sides, it is only necessary to use the first tongue and groove 4 and the second tongue and groove 5 on the left and right sides of the composite floor body 1, and to use the sliding insertion method to perform structural splicing. At the same time, the splicing slots 6 opened at the bottom of the two adjacent sets of composite floor bodies 1 can be aligned and the splicing strips 3 can be inserted into them to ensure the connection stability of the left and right sides of the composite floor body 1 after the connection.

[0029] After the entire composite flooring body 1 is laid, the environmentally friendly wear-resistant layer 101, together with the fiberglass layer 102, ensures the service life and strength of the structure. The densely woven fabric layer 103 and the antibacterial and mildew-proof layer 104 prevent unnecessary structural damage caused by external environmental factors. The buffer layer 105 provides a certain degree of structural protection for users, preventing excessive injury from falls during exercise.
