Description

Technical Field

[0001] This invention relates to the field of flooring technology, specifically to an indoor interlocking wear-resistant flooring and its installation structure for a comprehensive sports stadium. Background Technology

[0002] In comprehensive sports stadiums, the indoor interlocking wear-resistant flooring is used for sports flooring, which mainly comes in two types: sports wood flooring and artificial material sports flooring. Sports wood flooring includes solid wood flooring, composite wood flooring, and bamboo flooring; while artificial material sports flooring includes PVC sports flooring, silicone polyurethane sports flooring, and suspended interlocking sports flooring, etc. The wood flooring in indoor sports stadiums is generally permanent flooring. The prior art, disclosed in CN119754507A, discloses a fiber-reinforced plastic self-heating floor and its installation structure, relating to the field of flooring technology. The fiber-reinforced plastic self-heating floor includes a floor body; the floor body has a layered heating layer and a fiber reinforcement layer, with the heating layer located above the fiber reinforcement layer; the conductive ends of the heating layer are flush with the end faces of the floor body. In the installation structure, multiple floor bodies are assembled into a floor installation plane by end-to-end butt joints and staggered seams; multiple supporting joists are provided below the floor installation plane, corresponding to the gaps between two butt-jointed floor bodies. The fiber-reinforced plastic self-heating floor provided by this invention can create a warm and comfortable indoor environment for users, has a heating function, is easy and quick to install, and is reliable in use. The aforementioned disclosed technical solution also has the following shortcomings: The self-heating floor is assembled by end-to-end and staggered joints to form the flooring surface. Once the floor is installed, it is difficult to disassemble it in parts, making it difficult to repair or replace parts of the floor. Furthermore, this installation method results in poor sealing at the joints between the floorboards, which can easily lead to gaps after installation. At the same time, the keel frame supports the bottom of the floor, but the supporting area of ​​the keel frame at the floor joints is small, resulting in insufficient support. During continuous foot traffic, the floor is prone to sinking at the joints, reducing the flatness of the joints and seriously damaging the floor, thus reducing its service life. Summary of the Invention

[0003] Therefore, in order to overcome the above-mentioned shortcomings, the present invention provides an indoor spliced ​​wear-resistant floor slab for comprehensive sports stadiums and its paving structure.

[0004] This invention is implemented as follows: a splicing wear-resistant flooring for indoor use in a comprehensive sports stadium is constructed, including a floor and a joint plate. The floor has slots on both sides, which are inclined grooves extending from the lower outer side to the upper inner side. The joint plate has strips on both sides, which are inclined strips extending from the lower outer side to the upper outer side.

[0007] A paving structure includes a main keel frame, suspended uprights, locking plates, a central vertical groove, and magnetic grooves. The main keel frame has suspended uprights welded to its bottom. Two locking plates are provided and pressed onto the lower left and right sides of the suspended uprights. The locking plates are bolted to the indoor floor of the stadium, vertically fixing the suspended uprights to the indoor floor, ensuring the main keel frame is parallel to the indoor floor. The central vertical groove is embedded in the upper middle part of the main keel frame, and two magnetic grooves are embedded in the upper part of the main keel frame, located on both sides of the central vertical groove. Magnetic blocks are engaged and installed inside the magnetic grooves. The lower end of a joint plate is inserted into the central vertical groove.

[0008] Preferably, the main keel frame has adjustable grooves embedded in the interior of both the left and right sides, and the secondary keel frame has sliding plates at both ends of both the left and right sides. The two sliding plates are slidably installed in the adjustable grooves on the inner sides of the two main keel frames. The secondary keel frame is fixed between the two main keel frames by the locking of the sliding plates and the adjustable grooves. The secondary keel frame supports the lower end of the splicing point of the two adjacent floorboards.

[0009] Preferably, the bottom of the secondary keel frame is also equipped with an inclined support, which consists of a support column, a snap-fit ​​bottom frame and a stop plate. The upper end of the support column is welded with the snap-fit ​​bottom frame, the lower end of the secondary keel frame is snapped into the inner side of the snap-fit ​​bottom frame, the stop plate is vertically welded to the bottom of the support column, and the lower end of the support column stands on the lower end plane of the locking plate, with the stop plate abutting against the lower end side of the locking plate.

[0010] Preferably, an elastic plate is installed on the upper surface of the secondary keel frame, and an adsorption plate is provided on the upper surface of the elastic plate, with the adsorption plate located at the lower end of the gap between two adjacent front and rear splicing floorboards.

[0011] Preferably, a positioning post is also installed at the lower end of the adsorption plate.

[0012] Preferably, the upper and lower surfaces of the sliding plate are provided with extrusion strips, and the two extrusion strips abut against the upper and lower surfaces of the inner side of the adjusting groove.

[0013] Preferably, the upper end of the main keel frame is also equipped with an edge trimming skirt board, and the lower end of the edge trimming skirt board is provided with a magnetic strip inserted into the magnetic groove. The edge trimming skirt board is installed between the floor and the interior wall of the stadium. The upper end of the edge trimming skirt board presses against the edge of the floor, and a sandwich panel is provided at the connection end between the edge trimming skirt board and the floor.

[0014] The present invention has the following advantages: By providing an improved indoor interlocking wear-resistant floor slab and its paving structure for comprehensive sports stadiums, the present invention offers the following improvements compared to similar equipment: The present invention discloses an indoor interlocking wear-resistant floor slab and its paving structure for a comprehensive sports stadium. By incorporating a gap-jointing plate, which is vertically installed at the joint of two adjacent floorboards, the gap-jointing plate is longitudinally compressed when the floorboards expand due to heat, and elastically resets when the floorboards contract due to cold. This ensures the gap-jointing plate remains tightly connected at the joint, preventing gaps between the floorboards and preventing sweat from seeping down into the floor and affecting the normal heating function of the underfloor heating system. Furthermore, the ultra-wear-resistant surface layer of the floor does not obstruct the upward conduction of heat, avoiding heat waste and achieving energy-saving effects in the building.

[0015] The present invention discloses an indoor interlocking wear-resistant floor slab and its paving structure for a comprehensive sports stadium. By incorporating flexible magnetic strips and magnetic blocks, the flexible magnetic strips engage with the interlocking grooves and magnetically fix the joints of two front and rear interlocking floorboards, thus meeting the fixing requirements. Simultaneously, the elastic cooperation of the flexible magnetic strips and interlocking strips, as well as the rapid separation of the magnetic blocks from the magnetic grooves, allows for the quick removal of sections of the floorboard from the joint plate and the main keel frame, facilitating the repair or replacement of the underfloor heating system beneath the floor.

[0016] This invention discloses an indoor interlocking wear-resistant floor slab and its paving structure for a comprehensive sports stadium. It comprises a main keel frame and a secondary keel frame. After the main keel frames are installed, the position of the secondary keel frames installed between the two main keel frames is adjusted so that they are directly below the joints of the front and rear floor panels. This allows the secondary keel frames to support the lower ends of the joints. Simultaneously, two symmetrical inclined supports are installed at the lower ends of the secondary keel frames to enhance their support effect on the floor. With the support of the main and secondary keel frames, long-term foot traffic prevents the joints from sinking, thus avoiding damage to the underfloor heating system beneath the floor.

[0019] The following will be combined with the appendix Figure 1-8This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] Please see Figure 1-5 The present invention discloses an indoor splicing wear-resistant flooring for a comprehensive sports stadium, comprising a floor 1 and a joint plate 2. The floor 1 has a slot 11 on both the left and right sides, the slot 11 being an inclined groove extending from the lower outer side to the upper inner side. The joint plate 2 has a strip 21 on both sides, the strip being an inclined strip extending from the lower outer side to the upper outer side, and the slot 11 and the strip 21 are structurally matched. By engaging the slot 11 and the strip 21, the side of the floor 1 and the side of the joint plate 2 are spliced ​​together, and two adjacent floor 1s are spliced ​​and fixed together under the connection of the joint plate 2. The front surface of the floor 1 is embedded with a slot 12, and the rear surface of the floor 1 is fitted with a flexible magnetic strip 13. When splicing, the flexible magnetic strip 13 on the rear surface of the front floor 1 is inserted into the slot 12 on the front surface of the rear floor 1, and the flexible magnetic strip 13 is magnetically connected to the magnetic strip set inside the slot 12, so as to splice and fix the two adjacent floor 1s. The bottom of the floor 1 is also embedded with an embedded groove 14, and a magnetic block 15 is installed inside the embedded groove 14. The bottom of the floor 1 is provided with a paving structure 3, and the magnetic block 15 is engaged and installed on the paving structure 3. It is necessary to explain that the joint plate 2 is a corrugated steel structure and is made of 304 stainless steel. The joint plate 2 is vertically installed at the joint of two adjacent floor 1s. When the floor 1 is heated and expands, it compresses the joint plate 2 longitudinally. When the floor 1 is cooled and contracts, the joint plate 2 elastically returns to its original position, so that the joint plate 2 is always tightly connected at the joint of the two floor 1s, avoiding the formation of gaps between the floor 1s. Furthermore, the clips 21 on both sides of the joint plate 2 are made of spring steel, which has good elasticity and can be quickly inserted and fixed with the slots 11 of the floor 1. The flexible magnetic strip 13 uses natural rubber as its base and neodymium iron boron as its magnetic material. The flexible magnetic strip 13 engages with the insertion slot 12 and is magnetically fixed to meet the fixing requirements of the joint between two front and rear spliced ​​floorboards 1. At the same time, with the elastic cooperation of the flexible magnetic strip 13 and the locking strip 21, a part of the floorboard 1 can be removed from the joint plate 2 and the adjacent floorboards 1, so as to repair or replace the part of the floorboard 1. It also facilitates the maintenance and replacement of the underfloor heating system under the floorboard 1.

[0021] Floor 1 is composed of an ultra-wear-resistant surface layer 101, a decorative reinforcement layer 102, a high-density substrate layer 103, an elastic buffer layer 104, and a moisture-proof protective layer 105. The ultra-wear-resistant surface layer 101 is located on the upper surface of the decorative reinforcement layer 102, and the high-density substrate layer 103 is provided on the lower surface of the decorative reinforcement layer 102. The elastic buffer layer 104 is installed on the lower surface of the high-density substrate layer 103, and the elastic buffer layer 104 is located on the upper surface of the moisture-proof protective layer 105. It is necessary to explain that the ultra-wear-resistant surface layer 101 is made of a mixture of ultra-high molecular weight polyethylene and alumina ceramic particles, which can resist high-frequency trampling and mechanical friction, and will not hinder the upward conduction of heat, thus avoiding heat waste and achieving the effect of building energy conservation. The decorative reinforcement layer 102 is made of melamine resin impregnated paper material, which can maintain the appearance integrity of the floor 1. The high-density substrate layer 103 is composed of reconstituted bamboo fiber and high-density fiberboard, which can bear impact loads and prevent the floor 1 from deforming under impact. The elastic buffer layer 104 is made of micro-foamed rubber + EVA mixture, which can absorb the impact force of sports and prevent athletes' joint injuries. The moisture-proof protective layer 105 is made of glass fiber reinforced epoxy resin coating material, which isolates ground moisture and sweat from causing the floor 1 to deform.

[0022] The bottom of the floor 1 is also embedded with an embedded groove 14, and a magnetic block 15 is installed inside the embedded groove 14. The bottom of the floor 1 is provided with a paving structure 3, and the magnetic block 15 is engaged and installed on the paving structure 3. It is necessary to explain that the upper width of the embedding groove 14 is greater than the lower width, and the structure of the embedding groove 14 matches the structure of the magnetic block 15, so that the magnetic block 15 can slide into the embedding groove 14 and the lower end of the magnetic block 15 protrudes from the bottom of the floor 1. The part of the magnetic block 15 protruding from the bottom of the floor 1 is precisely stuck in the magnetic suction groove 35 and magnetically fixed. The magnetic block 15 is made of neodymium iron boron magnet and generates a magnetic attraction force of 25 N / cm² with the magnetic suction groove 35. Furthermore, the connection between multiple floor 1s and the main keel frame 31 is achieved by magnetically fixing the magnetic blocks 15 arranged in a distribution with the magnetic suction groove 35, which greatly improves the stability of the floor 1 splicing and fixing on the upper part of the main keel frame 31. Moreover, when disassembling a part of the floor 1, the magnetic blocks 15 and the magnetic suction groove 35 can be quickly separated, making it easy for the floor 1 to be removed from the main keel frame 31. Furthermore, two magnetic blocks 15 are installed at the front and rear center positions of the floor 1. The two magnetic blocks 15 in the middle are also engaged inside the magnetic groove 35 and magnetically fixed. When the floor 1s in the front and rear positions are installed in a staggered manner, the two magnetic blocks 15 in the middle of the rear floor 1 are magnetically connected with the magnetic blocks 15 at the near ends of the two adjacent floor 1s on the left and right sides of the front floor 1, which improves the firmness of the splicing of the front and rear floor 1s, thereby avoiding gaps at the splicing point of the front and rear floor 1s and preventing sweat from seeping down from the gaps to the bottom of the floor 1 and affecting the normal heating operation of the underfloor heating.

[0023] Please see Figure 6-8 The present invention provides a paving structure comprising a main keel frame 31, suspended uprights 32, locking plates 33, a central vertical groove 34, and magnetic grooves 35. The suspended uprights 32 are welded to the bottom of the main keel frame 31. Two locking plates 33 are provided and are pressed and installed on the left and right sides of the lower end of the suspended uprights 32. The locking plates 33 are fixed to the indoor floor of the stadium by bolts, thus vertically fixing the suspended uprights 32 to the indoor floor of the stadium, making the main keel frame 31 parallel to the indoor floor of the stadium. The central vertical groove 34 is embedded in the middle of the upper end of the main keel frame 31, and two magnetic grooves 35 are embedded in the upper end of the main keel frame 31. The two magnetic grooves 35 are located on both sides of the central vertical groove 34. Magnetic blocks 15 are engaged and installed inside the magnetic grooves 35. The lower end of the gap connecting plate 2 is inserted and installed inside the central vertical groove 34. It is necessary to explain that the main keel frame 31 is made of galvanized low carbon steel with a magnetic permeability of >5000μ, which can produce a highly efficient magnetic attraction effect with the magnetic block 15. Furthermore, multiple main keel frames 31 are located under the adjacent floor 1s installed on the left and right sides, providing support for the joints of the floor 1s. At the same time, under the action of the central vertical groove 34, the joint plate 2 is ensured to stand vertically above the middle of the main keel frame 31 to lock and fix the joints of the adjacent floor 1s on both sides, thereby improving the flatness of the surface of the floor 1 after splicing.

[0024] The main keel frame 31 has adjustable grooves 36 embedded in the interior of both sides. The secondary keel frame 37 has sliding plates 371 at both ends of both sides. The two sliding plates 371 are slidably installed in the adjustable grooves 36 inside the two main keel frames 31. The secondary keel frame 37 is fixed between the two main keel frames 31 by the locking of the sliding plates 371 and the adjustable grooves 36. The secondary keel frame 37 supports the lower end of the splice of the two adjacent floor 1s. The upper and lower surfaces of the sliding plates 371 are provided with extrusion strips 3711, and the two extrusion strips 3711 abut against the upper and lower surfaces inside the adjustable grooves 36. It is necessary to explain that the extrusion strip 3711 has an arc-shaped structure and is made of spring steel, which has good elasticity. The upper and lower extrusion strips 3711 can be elastically locked inside the adjustment groove 36 to fix the secondary keel frame 37 in the position after sliding adjustment between the two main keel frames 31. This allows the secondary keel frame 37 to be adjusted to be located exactly at the lower center of the splice of the front and rear floor 1 for synchronous support, and to provide equal support to the edges of the front and rear floor 1, so as to prevent the splice of the front and rear floor 1 from being dented during the process of walking on the ground.

[0025] The bottom of the secondary keel frame 37 is also equipped with an inclined support 38, which consists of a support column 381, a snap-fit ​​bottom frame 382 and a stop plate 383. The upper end of the support column 381 is welded to the snap-fit ​​bottom frame 382, ​​and the lower end of the secondary keel frame 37 is snapped into the inner side of the snap-fit ​​bottom frame 382. The stop plate 383 is vertically welded to the bottom of the support column 381, and the lower end of the support column 381 stands on the lower plane of the locking plate 33. The stop plate 383 abuts against the lower side of the locking plate 33. It is necessary to explain that the snap-fit ​​bottom frame 382 has a U-shaped structure, and its inner space fits perfectly with the secondary keel frame 37. The snap-fit ​​bottom frame 382 is firmly supported at the bottom of the secondary keel frame 37 by the inclined support column 381, which improves the stability of the secondary keel frame 37 installed between the main keel frame 31. When the secondary keel frame 37 is subjected to force, the support column 381 will tilt and transmit the force to the lower outer end, so that the abutment plate 383 is squeezed inward to the locking plate 33, preventing the support column 381 from falling off the locking plate 33 when the force is transmitted, improving the stability of the force, and preventing the secondary keel frame 37 from being stepped on when supporting the floor, which would cause the position of the secondary keel frame 37 to move. This ensures that the secondary keel frame 37 is stably supported at the edges of the front and rear floor 1, providing equal support force.

[0026] An elastic plate 373 is installed on the upper surface of the secondary keel frame 37, and an adsorption plate 374 is provided on the upper surface of the elastic plate 373. The adsorption plate 374 is located at the lower end of the gap between two adjacent front and rear splicing floor 1s. A positioning post 3741 is also installed at the lower end of the adsorption plate 374. The positioning post 3741 passes through the interior of the elastic plate 373. A positioning hole 372 is vertically passed through the interior of the secondary keel frame 37, and the positioning post 3741 is inserted into the positioning hole 372. It is necessary to explain that the elastic board 373 is made of rubber, which has good elasticity and can provide elastic buffer between the floor 1 and the secondary keel frame 37, so as to prevent displacement of the connection between the secondary keel frame 37 and the floor 1 during long-term stress. Furthermore, both the adsorption plate 374 and the positioning post 3741 are made of silicone, which has good corrosion resistance, durability, certain elasticity, and good moisture absorption capacity. The adsorption plate 374 abuts against the bottom of the splice of the two floorboards 1, which not only can play a role in shock absorption and cushioning, but also can adsorb the moisture at the splice of the two floorboards 1, preventing moisture from accumulating at the splice of the two floorboards 1 and causing the splice of the floorboards 1 to deform and warp. By using the positioning pins 3741 and positioning holes 372 for positioning and insertion, the elastic plate 373, adsorption plate 374 and secondary keel frame 37 can be disassembled during later maintenance, and the parts that need to be replaced can be quickly replaced.

[0027] The upper end of the main keel frame 31 is also equipped with an edge trimming skirt 4. The lower end of the edge trimming skirt 4 is provided with a magnetic strip inserted into the magnetic groove 35. The edge trimming skirt 4 is installed between the floor 1 and the indoor wall of the stadium. The upper end of the edge trimming skirt 4 presses the edge of the floor 1, and the connecting end face between the edge trimming skirt 4 and the floor 1 is provided with a sandwich panel 41. It is necessary to explain that the interlayer board 41 is made of rubber and has good elasticity. The interlayer board 41 is installed on the connecting end face between the edge skirting board 4 and the floor 1. The interlayer board 41 provides the effect of contraction and extension, improves the tightness of the connection between the edge skirting board 4 and the floor 1, avoids insufficient pressure of the edge skirting board 4 on the edge of the floor 1, which would cause the edge of the floor 1 on the indoor wall of the stadium to lift up, and improves the overall flatness of the floor 1 after installation.

[0028] This invention provides an improved indoor splicing wear-resistant floor slab and its paving structure for comprehensive sports stadiums, the working principle of which is as follows; First, the main keel frame 31 is installed on the indoor floor of the stadium. During installation, the main keel frame 31 is suspended and supported on the ground by the suspended uprights 32. Then, locking plates 33 are installed on the two sides of the lower end of the suspended uprights 32. The main keel frame 31 is installed parallel to the ground by bolts through the locking plates 33 and the inside of the ground. According to the length of the floor 1, multiple main keel frames 31 are arranged to form the floor 1 paving structure 3. The distance between each main keel frame 31 is half the length of the floor 1. This ensures that when the floor 1 is installed in a staggered manner, the main keel frame 31 can be directly below the splicing point of the two floor 1s on the left and right. The lower end of the suspended uprights 32 near the wall is not equipped with locking plates 33 to ensure that the main keel frame 31 near the wall can fit against the wall. The installation position of the edge skirting board 4 is reserved. Second, after the main keel frame 31 is installed, the position of the secondary keel frame 37 installed between the two main keel frames 31 is adjusted so that the secondary keel frame 37 is directly below the joint of the front and rear floor 1, so that the secondary keel frame 37 supports the lower end of the joint of the front and rear floor 1. At the same time, two symmetrical inclined supports 38 are installed at the lower end of the secondary keel frame 37 to improve the support effect of the secondary keel frame 37 on the floor 1. With the support of the main keel frame 31 and the secondary keel frame 37, long-term trampling will prevent the joint of the floor 1 from sinking and causing damage to the underfloor heating below the floor 1. Third, after the main keel frame 31 and the secondary keel frame 37 are installed, the floor 1 is laid. The lower end of the joint plate 2 is inserted into the central vertical groove 34 in the middle of the upper end of the main keel frame 31. Then, the slot 11 on the side of the floor 1 is inserted into the strip 21 of the joint plate 2. The floor 1 on both sides is spliced ​​and fixed by the joint plate 2. The magnetic block 15 at the bottom of the floor 1 is inserted into the magnetic groove 35 at the upper end of the main keel frame 31. The left and right floor 1 are laid. When laying the front and back floor 1, the flexible magnetic strip 13 on the back surface of the front floor 1 is inserted into the insertion groove 12 on the front surface of the rear floor 1 and magnetically fixed. At the same time, the lower ends of the front and back floor 1 are magnetically attracted to each other by the magnetic block 15, so that the floor 1 is firmly spliced ​​and the floor 1 is laid in a flat state. Fourth, install edge trimming skirting boards 4 on the completed floor 1 and the indoor walls of the stadium. The magnetic strip at the lower end of the edge trimming skirting board 4 is inserted into the magnetic groove 35 inside the upper end of the main keel frame 31 near the wall for fixation. The edge trimming skirting board 4 presses down on the edge of the floor 1. With the adhesion and fixation of the interlayer board 41, the four edges of the floor 1 are pressed down and fixed. At this time, the installation of the floor 1 is completed. Fifth, when maintenance is required, a vacuum suction cup is used to adhere to the surface of the floor 1 to be removed. A vertical pulling force of more than 25 N / cm² is applied to the vacuum suction cup to separate the magnetic block 15 from the magnetic suction groove 35. During the removal process, the elasticity of the clip 21 facilitates the upward movement of the clip groove 11 without causing disassembly obstruction. At the same time, the flexible magnetic strips 13 at the front and rear separate from the embedded groove 14 through elastic deformation, making it easy to remove individual floor 1 sections, thereby allowing for the repair or replacement of the underfloor heating system beneath the floor 1.
