[0050] In S2 of the installation method, a standard area venue, whether indoors or outdoors, is installed in sequence according to the number of each nail-free detachable elastic module; there is no need to place a construction line for an indoor venue, and the first block of the first route is placed on the ground of the venue at any one of the four corners of the venue, with the left edge and the rear edge close to the walls on both sides of the corner, and a certain gap is reserved between the walls on both sides to prevent the nail-free detachable elastic module from rubbing against the wall; if the installation position of the indoor venue is far from the wall, it is necessary to place the boundary line of the sports venue in advance, and place the first route of nail-free detachable elastic modules on the base ground at any one of the four corners of the venue, with the left edge and the rear edge respectively Do not align with the boundary lines on both sides of any corner of the venue; if there is a sports fence in the outdoor venue, place the first piece of the first nail-free disassembly and assembly elastic module on the base ground at any one of the four corners of the venue, with the left edge and the rear edge close to the fence posts on both sides of the corners of the venue, and reserve a certain gap between the fence posts on both sides to prevent the nail-free disassembly and assembly elastic module from rubbing against the fence posts; if there is no sports fence in the outdoor venue, it is necessary to place the boundary line of the sports venue in advance, place the first nail-free disassembly and assembly elastic module on the base ground at any one of the four corners of the venue, with the left edge and the rear edge aligned with the boundary lines on both sides of any corner of the venue.

[0051] In S2 of the installation method, for a non-standard area venue, whether indoor or outdoor, when laying the first piece of the first nail-free detachable elastic module, the right connecting fork 42 installed on the third support 13 of the first nail-free detachable elastic module must be removed first, and then a straight line cut is made along the rear end facade of the third support 13. After cutting, part of the first support 11 is used as the first piece of the first route at the beginning, and the other part is used for finishing. If it is not applicable for finishing, the complete nail-free detachable elastic module is used for cutting for finishing.

[0052] In the installation method S2, a standard area venue, whether indoors or outdoors, has sufficient operating space without the obstruction of walls or sports fences. A fastener 5 is provided on the right edge of the rightmost route of the venue to connect the front and rear adjacent nail-free detachable elastic modules, and a connecting fork 4 is provided on the front edge of the venue to connect the left and right adjacent nail-free detachable elastic modules. Therefore, when laying the first route of nail-free detachable elastic modules, the left lower edge of the first route of nail-free detachable elastic modules of the venue, the front and rear adjacent fifth support 15 and the left end of the first support 11 are connected and fixed through the corresponding through holes using hexagon socket bolts slightly longer than the hexagon socket bolts used by the connecting fork 4 and the fastener 5. At the same time, an electric drill is used to configure the four-legged claw 6 at the joint of the rear ends of the two adjacent nail-free detachable elastic modules. Use a drill bit with the same diameter as the column foot, and according to the four-legged positions of the four-legged claws 6, punch holes across the joints of the two adjacent nail-free disassembly and assembly elastic modules, inject structural glue into the holes, and then press the four column feet of the four-legged claws 6 into the corresponding holes, so that the four-legged claws 6 span the joints of the two adjacent nail-free disassembly and assembly elastic modules, and complete the connection and fixation of the first nail-free disassembly and assembly elastic modules of the left and right adjacent roads; if there are obstacles such as walls or sports fences, the four-legged claws 6 are set at the joints of adjacent assembled modules along the four sides of the venue in the same way; for the edges where the four-legged claws 6 are set, the connecting forks 4 and fasteners 5 located under the four sides of the venue need to be removed in advance to prevent the connecting forks 4 and fasteners 5 protruding from the edges of the nail-free disassembly and assembly elastic modules from causing the gaps from the wall and the sports fence to be too large.

[0053] In S2 of the installation method, for non-standard area venues, whether indoors or outdoors, where the edge of the nail-free disassembly elastic module needs to be close to a wall or a sports fence, or where the wall or the sports fence forms an obstacle to the side connection and there is no operating space, four-legged claws 6 are used to connect and fix the adjacent nail-free disassembly elastic modules at the edge of the venue. For the edges where the four-legged claws 6 are set, the connecting forks 4 and fasteners 5 located under the four sides of the venue need to be removed in advance to prevent the connecting forks 4 and fasteners 5 protruding from the edges of the nail-free disassembly elastic module from causing excessive gaps from the wall and the sports fence.

[0054] In S2 of the installation method, for standard area sites, the supporting end heads protruding from the left edge of the first row of nail-free disassembly and assembly elastic modules and the right edge of the last row are cut off along the edge to make them flush in the factory; for non-standard area sites, before installing the first row of nail-free disassembly and assembly elastic modules, a cutting machine can be used to cut off the supporting end heads protruding from the left side of the panel 10 to make the left edge of the first row of nail-free disassembly and assembly elastic modules flush and reduce the gap between the left edge and the wall or sports fence.

[0055] Another object of the embodiment of the present application is to provide a method for dismantling a universal indoor and outdoor detachable nailless sports wooden floor, the dismantling method comprising the following steps:

[0056] S01, taking out the four-legged claws 6, releasing the connection and fixation of the four-legged claws 6 to the edges of the four sides of the venue without nails for disassembly and assembly of the elastic module;

[0058] S03, pull the front end of the last nail-free disassembly elastic module of the rightmost line to the left to disengage it from the adjacent nail-free disassembly elastic module, and the last nail-free disassembly elastic module of the rightmost line can be removed; according to this method, the nail-free disassembly elastic modules are removed piece by piece and line by line from front to back and from right to left;

[0059] S04, placing the nail-free disassembly and assembly elastic module at a designated location for storage and standby; at this time, the nail-free disassembly and assembly elastic module is in a state that it can be reassembled at any time.

[0060] The present application replaces the layered surface boards, bearing boards and keels in the existing detachable sports wood floor technology through the one-piece molding of the one-piece nailless floor module 1; the one-piece nailless floor module 1 as a separate individual is connected and fixed horizontally and vertically through the connecting fork 4, the fastener 5 and the four-legged claws 6, so as to ensure the integrity of the large-area paving, so that the present application can obtain the complete and flat large surface required for sports, and realize the rapid installation and removal of the present application, as well as the repeatable disassembly and reuse of the general nailless sports wood floor technology for indoor and outdoor use; the present application does not use any solid wood materials, saves forest resources, and is conducive to the sustainable development of the ecological environment; the present application does not use any nails for the nailless setting and integration of connection and fixation, which greatly reduces the structural components, and greatly reduces the comprehensive cost including the material cost and the production cost of the repeated nailless disassembly and assembly elastic module, and the use and maintenance costs are low, which has the basis for large-scale promotion and use.

[0082] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application; the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the present application and its application or use; the following will be combined with the drawings and specific embodiments to describe the specific implementation of the present application in detail.

[0083] Example 1.

[0084] like Figure 1 to Figure 14 As shown, an embodiment of the present application provides a universal indoor and outdoor detachable nailless sports wooden floor, including multiple nailless detachable elastic modules, the nailless detachable elastic module includes an integrated nailless floor module 1, a small elastic rubber pad 2, a large elastic rubber pad 3, a connecting fork 4, a fastener 5 and four claws 6; through the connection and simple detachable setting of the connecting fork 4 and the fastener 5 to connect adjacent nailless detachable elastic modules, the nailless detachable elastic modules are quickly installed and removed, thereby realizing the repeatable disassembly and assembly of the present application.

[0085] The integrated nail-free floor module 1 is a polymer composite wood plastic elastic product, which is environmentally friendly and non-toxic, and is friendly to human health and the ecological environment. As a tough and elastic material, it has the advantages of strong plasticity, pressure resistance, impact resistance, high and low temperature resistance, moisture resistance, and long service life. As a product form of polymer composite wood plastic, wood plastic flooring is widely used. At the same time, it can also prevent insects and termites, so wood plastic flooring can be used in complex environments where traditional solid wood products cannot be used; compared with solid wood products, it is more resistant to storage, can be stored indoors, and can be stored outdoors at will. It has low requirements for the storage environment and a higher number of repeated turnover uses of the product.

[0086] Compared with extrusion production, which can only produce products with simple structural shapes like narrow strips, the advantages of using the plasticity of plastic materials for molding production are: good repeatability, simple operation, and product quality is not affected by the operator and external conditions; the product molding cycle is short, complex structures are molded in one time, the size of the pressed products is precise, the surface of the pressed products is smooth and smooth, and the surface treatment is more convenient; high-intensity pressure makes the mass density of the pressed products larger and stronger, the product stability is better, the cold and hot expansion rate is low, the bending, compression and tensile resistance are stronger, the load-bearing capacity is better, and the comprehensive cost of materials is lower.

[0087] The integrated nailless floor module 1 is obtained by uniformly mixing and stirring a plastic material made of high molecular weight polyethylene, wood powder and fiber, nano-active calcium carbonate and other additives, granulating the material, and then melting it into a semi-fluid or paste state at high temperature, and then putting it into a special compression molding mold in a hydraulic press with a hydraulic pressure of ≥500 tons, and through the strong pressure of the hydraulic press, the integrated compression molded wood-plastic product is obtained by one-time compression molding; after compression molding, the integrated compression molded wood-plastic product is taken out from the mold, and put into a grinder to grind the upper surface of the floor to remove the smooth resin film layer covering the upper surface, so as to facilitate the attachment of sports paint or the sticking of the anti-skid and wear-resistant layer, that is, a single floor module is obtained without the limit grooves and through holes of each support, the lower edge of the front tenon to the upper plane space of the first support 11, and the lower edge of the right tenon to the lower edge of the panel 10;

[0088] Use a slotting machine to slot at the designated positions of the tenon groove and each limiting groove, and slot out the tenon groove and each limiting groove; slot from the lower edge of the front tenon tongue to the upper plane of the first support 11 and from the lower edge of the right tenon tongue to the lower edge of the panel 10 to obtain a complete tenon tongue matching the tenon groove; use a punching machine to drill holes at the designated positions of each positioning hole, and drill out each through hole, so as to obtain an integrated nailless floor module 1;

[0089] After the product is molded and formed, the upper and lower molds of the molding mold are opened, and the product needs to be taken out from the lower mold. However, the grooves recessed in the vertical surface of the product, such as the mortise and tenon grooves, the various limiting grooves, and the recessed space from the bottom edge of the front tenon tongue to the upper plane of the first support 11 and the bottom edge of the right tenon tongue to the bottom edge of the panel 10, are in a locked state with the molding protrusions of the lower mold, forming an obstruction, resulting in the product being unable to be taken out; for example, the mortise and tenon grooves have upper and lower wings that produce obstructions in the up and down directions, the upper and lower walls of the various limiting grooves produce obstructions, the recessed space from the bottom edge of the front tenon tongue to the upper plane of the first support 11 and the bottom edge of the right tenon tongue to the bottom edge of the panel 10, and the tenon tongue and the upper plane of the first support 11 produce obstructions in the up and down directions; therefore, direct molding is performed once, and the product is smoothly taken out from the lower mold, which requires that the molding protrusions of the various grooves of the lower mold be able to retract quickly after the molding is completed to eliminate the obstruction to the product removal. The obstruction and rapid reset at the next molding will greatly increase the manufacturing cost of the molding die, greatly increase the number of parts of the molding die, reduce the durability and service life of the molding die, and significantly increase the maintenance cost of the molding die. Especially in the case of large-area single products such as the molded one-piece nailless floor module 1, it will also affect the mass density of the molded product to a certain extent, indirectly affecting the bearing performance of the molded product, and the overall cost is high; therefore, without setting various groove forming protrusions in the molding die, after the product is molded, the post-processing method of grooving by a grooving machine and punching by a punching machine can be used, so that the one-piece nailless floor module 1 can be obtained at the lowest cost and the product production efficiency can be improved to ensure product quality. At the same time, the use efficiency of the molding die can be increased, the cost of the above-mentioned series of molding die can be avoided or significantly reduced, and the service life of the molding die can be increased.

[0090] like Figure 5 As shown, two reinforcing supports connect the first support 11, the second support 12, the third support 13, the fourth support 14, and the fifth support 15 in the front-to-back direction to enhance the bearing performance and integration of the integrated nailless floor module 1; as a gain measure of the present application: steel bars are built into the reinforcing supports and each support to further enhance and strengthen the longitudinal and lateral deformation resistance, seismic resistance, and tensile strength of the integrated nailless floor module 1; before molding production, the steel bars are placed at the corresponding positions of the designated parts in the special molding mold of the integrated nailless floor module 1, and the steel bars can be built in during normal molding production.

[0091] like Figure 2~Figure 5 As shown, the upper end of the integrated nailless floor module 1 is provided with a panel 10, and the lower end and the back of the panel 10 are provided with multiple supports. The bottom surfaces of the multiple supports are provided with small recesses and large recesses recessed in the bottom surface, and a small elastic rubber pad 2 is connected in the small recess by adhesive sleeve, and a large elastic rubber pad 3 is connected in the large recess by adhesive sleeve; the multiple supports include a first support 11, a second support 12, a third support 13, a fourth support 14, and a fifth support 15; the first support 11 is provided at the lower edge of the front end of the panel 10, and a left connecting fork 41 is installed on the left side of the front facade through a front limiting groove 111 and multiple through holes, and the right side of the front facade and the protruding part are connected through multiple through holes A front fastener 51 is installed; a right connecting fork 42 is installed on the left side of the front end facade of the third support 13 through a rear limit groove 131 and multiple through holes; the fifth support 15 is arranged at the lower edge of the rear end edge of the panel 10, and the left side of the rear end facade passes through a through hole corresponding to the outermost through hole of the left end of the first support 11. When it is used for large-area installation, on the left side of two integral nailless floor modules 1, hexagon socket bolts are used to penetrate and connect the front and rear adjacent integral nailless floor modules 1; the right side of the rear end facade and the protrusion of the fifth support 15 are installed with a rear fastener 52 through a through hole; through the above settings, a nailless disassembly and assembly elastic module for repeated disassembly and assembly is formed in this application.

[0092] like Figure 5As shown, the elastic rubber pads at the bottom surfaces of the first support 11 and the fifth support 15 at the edge of the integrated nailless floor module 1, and the left and right ends of the bottom surfaces of the second support 12, the third support 13, and the fourth support 14 are all small elastic rubber pads 2; the middle position of the bottom surface of the second support 12, the third support 13, and the fourth support 14 is also the middle position of the nailless floor module 1, and are all large elastic rubber pads 3; the thickness of the small elastic rubber pad 2 is the same as the thickness of the large elastic rubber pad 3, and the volume of the small elastic rubber pad 2 is half of the volume of the large elastic rubber pad 3; the arrangement of the large and small elastic rubber pads makes the nailless disassembly and assembly of the elastic module After the blocks are assembled and put into use, athletes walk, run, jump and step on the upper surface of the assembled adjacent nail-free disassembly and assembly elastic module panels 10. When the soles of the feet generate downward gravity and impact force at the edge seams of adjacent panels 10, the instantaneous deformation and vibration frequency generated are consistent with those in the middle position of the panel 10, and the physical and mechanical properties such as elasticity, shock absorption, cushioning and rebound of the seams of adjacent panels 10 and the middle position of the panel 10 are consistent, ensuring that the large venue of the present application can be used normally when conducting sports competitions and fitness exercises.

[0093] like Figure 2 , Figure 3 As shown, the front facade and the right facade of the panel 10 are provided with tenons protruding from the facades; the rear facade and the lower edge of the left facade of the panel 10 are provided with tenons matching the tenons; after multiple nail-free detachable elastic modules are assembled in the horizontal direction of front, back, left and right, the tenons and tenons that are sleeved and connected can ensure that the edges of adjacent nail-free detachable elastic module panels 10 and the upper surface of the floor on both sides of the edges of the panels 10 are always in the same state, instantaneous deformation and vibration frequency, so as to avoid the different horizontal heights of the edges of adjacent panels 10 and the upper surface of the floor on both sides of the edges of adjacent panels 10 in intense competitive sports, which may cause shoe soles to collide and endanger personal safety, and different instantaneous deformation and vibration frequencies to affect technical performance.

[0094] like Figure 2~Figure 4 , Figure 6 , Figure 8 , Fig.11 As shown, the connecting fork 4 is provided with a pointed pin 424, through which the left connecting fork 41 and the right connecting fork 42 are connected, so as to realize the connection of adjacent integrated nailless floor modules 1 in the left and right directions, and enable the integrated nailless floor module 1 on one side of the left connecting fork 41 to swing to the left around the pointed pin 424, and quickly dock and assemble with the integrated nailless floor module 1 on the left side; the left limiting plate 412 is inserted into and tightly attached to the front limiting groove 111, giving the left connecting fork 41 the ability to resist pulling to the left in addition to being fastened in place by the hexagon socket bolt; the right limiting plate 422 is inserted into and tightly attached to the rear limiting groove 131, giving the right connecting fork 42 the ability to resist pulling to the right in addition to being fastened in place by the hexagon socket bolt.

[0095] like Figure 2 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 As shown, the front fastening limit plate 512 is tightly attached to the rear end facade of the right side protrusion of the first support 11, giving the front fastener 51 the ability to resist forward pulling outside the position of the hexagon socket bolts, and the front fastening reinforcement plate 513 is fixed to the front end facade of the first support 11 by the hexagon socket bolts, thereby improving the ability of the front fastener 51 to resist rightward pulling outside the position of the hexagon socket bolts; the rear fastening limit plate 522 is tightly attached to the front end facade of the right side protrusion of the fifth support 15, giving the rear fastener 52 the ability to resist forward pulling outside the position of the hexagon socket bolts, and the rear fastening reinforcement plate 523 is fixed to the rear end facade of the fifth support 15 by the hexagon socket bolts, thereby improving the ability of the rear fastener 51 to resist rightward pulling outside the position of the hexagon socket bolts.

[0096] like Figure 1 , Figure 5 , Figure 8~Figure 10 As shown, the fastener 5 is provided with a tightening bolt 515, by which the adjacent integrated nailless floor modules 1 assembled left and right, front and back are connected and fixed in the front and back direction; when the integrated nailless floor modules 1 are installed in a large area, the first route is installed first, and the routes are assembled one by one on the right side of the first route; when installing the first route, the through bolts are used on its left side to penetrate the corresponding through holes of the front and rear adjacent first supports 11 and the fifth supports 15 and lock them, so as to realize the connection and fixation of the left edge of the floor site; the fastener 5 is used on the right side of the last route of the floor site to realize the connection and fixation of the right edge of the floor site; when the site is limited and there is not enough operating space to connect the edges of the left and right sides of the floor site with bolts and fasteners 5, the four-legged claws 6 are used on the upper surface of the floor to cross the left and right joints of the two adjacent front and rear integrated nailless floor modules 1 to connect and fix the left and right edges of the floor site; similarly, the front and rear edges of the floor site cannot use the connecting fork 4 Or other common connectors are used for connection, and four claws 6 are also used on the upper surface of the floor to span the front-to-back joints of the adjacent left and right integrated nailless floor modules 1 to connect and fix the front and back edges of the floor venue.

[0097] By means of the cross-connection and locking of the connecting forks 4 and the fasteners 5 left and right and front and back, the adjacent integral nailless floor modules 1 cannot be separated and displaced left and right and front and back, and by means of the supplementary connection and locking of the four edges of the floor venue by bolts and four claws 6, the present application can obtain a large flat surface required for a stable and flat sports venue.

[0098] When removing the floor module 1, take out the four-legged claws 6 and release the cross-seam connection and fixation of the four-legged claws 6 to the four edges of the venue; if there is a fastener 5 on the rightmost side of the venue, remove the tensioning bolt 515, release the front-to-back connection of the rightmost side, take out the pointed pin 424, release the connection with the adjacent integrated nailless floor module 1 on the left, pull its front end to disengage it from the adjacent integrated nailless floor module 1, and the removal of the last integrated nailless floor module 1 on the rightmost side can be completed; according to the method of first removing the tensioning bolt 515 and then taking out the pointed pin 424, from front to back, from right to left, one by one, one by one, the complete removal of the entire floor venue can be completed, and it can be reinstalled at any time.

[0099] like Figure 1 , Figure 5 , Figure 8 , Fig.11 , Fig.12 As shown, when multiple nail-free disassembly and assembly elastic modules are assembled and docked, the left edge of the nail-free disassembly and assembly elastic module on the right side uses the pointed pin 424 as an axis to dock to the right with the right edge of the nail-free disassembly and assembly elastic module on the left side; the S-shaped arc end on the left side of the first support 11 of the right side nail-free disassembly and assembly elastic module corresponds to the S-shaped arc end on the right side of the third support 13 of the left side nail-free disassembly and assembly elastic module; the protruding and indented left side end of the second support 12 of the right side nail-free disassembly and assembly elastic module corresponds to the indented and protruding right side end of the fourth support 14 of the left side nail-free disassembly and assembly elastic module; the protruding and indented left side end of the fourth support 14 of the right side nail-free disassembly and assembly elastic module corresponds to the indented and protruding right side end of the second support 12 of the left side nail-free disassembly and assembly elastic module;

[0100] Further, the arc-shaped protrusion at the left end of the first support 11 of the right side nail-free disassembly elastic module can, after docking, limit the forward displacement of the right side nail-free disassembly elastic module on the left side; the protruding and retracted left ends of the second support 12 and the fourth support 14 of the right side nail-free disassembly elastic module can, after docking, limit the backward displacement of the right side nail-free disassembly elastic module on the left side;

[0101] Furthermore, the arc-shaped protrusion at the left end of the first support 11 of the right side nail-free disassembly and assembly elastic module, when docking with the arc-shaped recessed portion at the right end of the third support 13 of the left side nail-free disassembly and assembly elastic module, can rely on the left side nail-free disassembly and assembly elastic module to make certain corrections to its own front and rear position, thereby ensuring the precise position of each nail-free disassembly and assembly elastic module after assembly, and making the left and right ends of other supports dock more tightly; the arc-shaped protrusion and the arc-shaped recessed portion as well as the connection limit of each support end enable the nail-free disassembly and assembly elastic module to obtain the positioning capability not only relying on the connecting fork 4 and the fastener 5, but also together with the connecting fork 4 and the fastener 5 to assemble and position the nail-free disassembly and assembly elastic module, forming mutual gain and mutual reinforcement, thereby greatly enhancing the stability and connection firmness of the present application under the impact of intense sports competitive movements.

[0102] Furthermore, after the arc-shaped protrusions are connected to the arc-shaped recesses and the other supporting ends are connected accordingly, the protruding parts extend to the bottom of the edges of the adjacent panels 10, thereby providing mutual support for the joints of the adjacent panels 10 and promoting the integrity of the large venue and large plane of the present application;

[0103] Furthermore, when athletes walk, run, jump, or step on the edge joints of the panels 10 of the adjacent nail-free detachable elastic modules in the front and rear directions after assembly, and on the upper surfaces of the panels 10 on both sides of the edge joints, and when the soles of the feet generate downward gravity and impact force at the edge joints of the adjacent panels 10, the edge joints and both sides of the edge joints generate the same instantaneous deformation and tremor frequency, as well as the same physical and mechanical properties such as elasticity, shock absorption, buffering, and rebound, thereby ensuring that the large venue of the present application can normally perform the competitive technical level of athletes during sports competitions and fitness exercises;

[0104] Furthermore, the corresponding connection between the arc-shaped protrusion and the arc-shaped recess and the corresponding connection between the other supporting ends, together with the mutually connected tenons and mortise grooves, together ensure the stability, integrity, and consistency of the movement performance of the adjacent nail-free disassembly and assembly elastic modules after assembly, forming mutual reinforcement and mutual benefit;

[0105] Furthermore, the upper edges of the vertical surfaces of the supporting end heads protruding from the edge of the panel 10 are all arc-shaped, which reduces the collision of corners when the elastic modules are connected without nails, and is conducive to the smooth connection of the elastic modules.

[0106] like Figure 7 , Figure 8 , Fig.13 , Fig.14As shown, the four column feet of the four-legged claws 6 are respectively inserted into the holes on both sides of the joints of adjacent integrated nailless floor modules 1 at the front and back and left and right edges, so that the adjacent integrated nailless floor modules 1 cannot be displaced or offset, and the joints are always ensured to be tight, avoiding the lack of stable connection between the integrated nailless floor modules 1 at the edge. Under the repeated influence of the impact force and vibration generated in sports and competitive activities, different tremors and elastic reactions from the integrated nailless floor modules 1 in the edge appear, affecting the technical performance of athletes; avoiding deviation under the influence of the impact force and vibration generated in sports and competitive activities, thereby affecting the position stability of other integrated nailless floor modules 1, as well as the normal performance of physical and mechanical properties such as elasticity and shock absorption; the four-legged claws 6 are at the edge of the venue floor and do not belong to the sports activity area, so they do not affect the normal sports and competitive activities of the floor venue.

[0107] The above-mentioned embodiment provides a universal indoor and outdoor detachable nailless sports wooden floor.
