Description

Technical Field

[0001] This utility model relates to the field of flooring product technology, and in particular to a type of flooring. Background Technology

[0002] Flooring is typically used for decorative paving of building floors and ground surfaces. Flooring made of materials such as rubber and soft rubber can achieve certain functions such as drop prevention and shock absorption.

[0003] To facilitate transportation and adapt to surface installation of various sizes, existing flooring is usually produced by disassembling it into multiple individual flooring units, which are then assembled on-site according to the required installation area.

[0004] However, most current flooring systems use outward-extending protrusions and inward-recessed grooves on opposite sides of individual floorboards. The protrusions of one floorboard are inserted into the grooves of an adjacent floorboard to achieve splicing and installation. This method involves stacking multiple floorboards along their sides to form a single unit. This splicing method is prone to causing a floorboard to detach from its adjacent unit when it deforms, increasing the risk of water seepage and leakage, and resulting in poor assembly stability. Utility Model Content

[0005] The main objective of this invention is to propose a flooring system designed to improve the stability and reliability of flooring assembly connections.

[0006] To achieve the above objectives, the flooring proposed in this utility model has a top surface, a bottom surface, and a splicing side surface connecting the top surface and the bottom surface. The splicing side surface is provided with at least one outwardly extending boss and at least one inwardly recessed groove. The boss and the groove are alternately arranged along the extension direction of the splicing side surface. The top surface of the boss is provided with a limiting rib, and the inner top wall of the groove is provided with a limiting groove. The splicing side surface of one flooring is used to fit against the splicing side surface of another adjacent flooring. The bosses and grooves of two adjacent floorings are sequentially engaged and inserted, and the limiting ribs are correspondingly engaged with the limiting grooves.

[0007] In one embodiment, the bottom surface is recessed and provided with a fastening groove, which extends through the splicing side and the fastening grooves of two adjacent floorboards are connected to each other; the floorboards also include fasteners, which are inserted into the fastening grooves of at least two adjacent floorboards to connect at least two adjacent floorboards.

[0008] In one embodiment, the fastening groove is located at the corner of the bottom surface, the fastening groove is an arc-shaped groove, the fastener is a collar, and the fastener is sleeved on at least two adjacent corners of the bottom surface of the floor.

[0009] In one embodiment, the length of the boss gradually decreases along the direction away from the splicing side, and the slot is configured to correspond to the shape of the boss.

[0010] In one embodiment, the opposite sides of the boss are respectively arranged at an angle to the splicing side. Alternatively, one side of the boss is perpendicular to the splicing side, and the other opposite side of the boss is arranged at an angle to the splicing side.

[0011] In one embodiment, the floor includes a first sheet, a second sheet, and a third sheet stacked sequentially, wherein the surface of the first sheet facing away from the second sheet is the top surface, and the surface of the third sheet facing away from the second sheet is the bottom surface, and the second sheet is made of polyurethane foam.

[0012] In one embodiment, the first sheet is made of thermoplastic polyurethane elastomer; and / or, the third sheet is made of thermoplastic polyurethane elastomer; and / or, the first sheet, the second sheet, and the third sheet are integrally molded structures.

[0013] In one embodiment, the bottom surface is provided with a drainage groove, which extends through opposite sides of the floor and the drainage grooves of two adjacent floors are connected to each other.

[0014] In one embodiment, the drainage trough includes a first water trough and a second water trough, the first water trough extending along a first direction and the second water trough extending along a second direction, the first direction and the second direction intersecting each other, and the first water trough and the second water trough being alternately connected.

[0015] In one embodiment, the bottom surface is provided with anti-slip protrusions.

[0016] This invention solves the problem of easy loosening of traditional single-protrusion and grooved floorboards by alternately setting protrusions and grooves on the sides of the floorboard joints to form an interlocking structure. The physical interlocking of the protrusions and grooves restricts the lateral displacement of adjacent floorboards. Specifically, a limiting rib is added to the top surface of the protrusion to cooperate with the limiting groove on the inner top wall of the groove, forming a vertical limit after insertion to prevent separation and simultaneously enhancing the lateral displacement restriction effect of the protrusions and grooves, further preventing relative separation of adjacent floorboards. The alternating arrangement of protrusions and grooves creates multi-point contact during splicing, dispersing the force at a single point and reducing the impact of local deformation on the overall connection. Furthermore, the complete fit design of the adjacent floorboard joint sides further eliminates gaps, enhances the tightness of the connection, avoids the risk of water seepage and leakage, and effectively improves the connection stability and reliability of the floorboards.

[0029] In existing technologies, flooring is typically manufactured by disassembling it into multiple individual units, which are then assembled using protrusions and grooves. This traditional assembly method relies on the overlapping connection of protrusions and grooves on one side. When individual flooring units experience thermal expansion and contraction or are subjected to external impacts, they are prone to deformation, creating gaps between the contact surfaces of adjacent units and leading to loosening or even separation at the joints. Especially during long-term use, localized deformation gradually weakens the binding force of the single-point contact, allowing moisture to easily seep into the flooring from the loosened areas, causing problems such as water accumulation, mold growth, or structural damage. To address these issues, this utility model proposes a flooring 100.

[0030] Please see Figures 1 to 5 In one embodiment of the present invention, the floor 100 has a top surface 11, a bottom surface 51, and a splicing side surface 70 connecting the top surface 11 and the bottom surface 51. The splicing side surface 70 is provided with at least one outwardly extending boss 71 and at least one inwardly recessed groove 73. The boss 71 and the groove 73 are alternately arranged in sequence along the extension direction of the splicing side surface 70. The top surface 11 of the boss 71 is provided with a limiting rib 711, and the inner top wall of the groove 73 is provided with a limiting groove 713. The splicing side surface 70 of one floor 100 is used to fit with the splicing side surface 70 of another adjacent floor 100. The boss 71 and the groove 73 of the two adjacent floor 100 are sequentially engaged and inserted, and the limiting rib 711 is correspondingly engaged with the limiting groove 713.

[0031] In this application, the boss 71 can refer to a block-shaped structure protruding outward from the splicing side 70, which can be implemented using a trapezoidal cross-section design, with its top plane and bottom surface 51 forming a supporting surface. The slot 73 can refer to a recessed receiving space inside the floor 100, which can be implemented using a groove structure that complements the shape of the boss 71. The groove depth can be equal to or greater than the height of the boss 71 to form an assembly allowance. The limiting rib 711 refers to a strip-shaped protrusion extending longitudinally along the top surface 11 of the boss 71, which can be implemented using a block structure design with a semi-circular or square cross-section. The limiting groove 713 refers to a groove on the inner wall of the top of the slot 73, which can be implemented using an arc-shaped or square groove that matches the cross-section of the limiting rib 711, with the groove depth and the rib height forming an interference fit.

[0032] Specifically, adjacent floorboards 100 form a continuous interlocking structure through the alternating insertion of protrusions 71 and slots 73 during splicing. When the two splicing sides 70 are fully fitted, each protrusion 71 is embedded in the corresponding slot 73, and the side walls of the protrusion 71 and the inner wall of the slot 73 form surface contact to resist lateral shear force. The limiting ribs 711, after being inserted into the limiting grooves 713, generate vertical constraints to prevent the floorboards 100 from shifting vertically when subjected to external forces. The alternating arrangement of multiple protrusions 71 and slots 73 forms distributed stress points. When the floorboards 100 deform due to temperature changes, each contact point shares the stress collaboratively, preventing the overall structure from failing due to excessive deformation at a single connection point.

[0033] Compared to existing technologies, traditional flooring splicing structures achieve connection only through linear contact between a single protrusion and a groove, which is prone to local separation under uneven stress. This solution utilizes an alternating arrangement of multiple sets of protrusions 71 and slots 73 to form a mesh-like interlocking structure, significantly increasing the contact area and friction. Simultaneously, the vertical interlocking design of the limiting ribs 711 and grooves further creates a three-dimensional limiting mechanism. Under impact loads, stress is dispersed and transferred through multiple contact points, effectively reducing the load intensity per unit area. Through this technical solution, the connection stability between adjacent floorboards 100 is significantly improved, effectively resisting horizontal displacement and vertical separation. The multi-point contact structure reduces the impact of local deformation on the overall splicing effect, effectively preventing relative separation and movement between adjacent floorboards 100, achieving a stable connection between multiple floorboards 100, reducing the risk of leakage due to loose connections, and improving the structural stability and reliability of the floorboards 100.

[0034] In addition, the floor 100 can form complementary splicing sides 70 on two opposite sides. Complementary means that the positions of the protrusions 71 and the slots 73 on the two splicing sides 70 are relatively complementary, so that the same floor 100 can be spliced ​​together in sequence, which facilitates the mass production of the floor 100.

[0035] The technical solution of this utility model solves the problem of easy loosening of traditional single protrusions and grooves by alternately setting protrusions 71 and grooves 73 on the splicing side 70 of the floor 100. The physical interlocking of the protrusions 71 and grooves 73 restricts the lateral displacement of adjacent floor 100s. Specifically, the top surface 11 of the protrusion 71 is equipped with a limiting rib 711 that cooperates with the limiting groove 713 on the inner top wall of the groove 73, forming a vertical limiting after insertion to prevent separation. This also enhances the lateral displacement limiting effect of the protrusions 71 and grooves 73, further preventing relative separation of adjacent floor 100s. The alternating arrangement of protrusions 71 and grooves 73 creates multi-point contact during splicing, dispersing the force at a single point and reducing the impact of local deformation on the overall connection. Simultaneously, the complete fit design of the splicing side 70 of adjacent floor 100s further eliminates splicing gaps, enhances the tightness of the connection, avoids the risk of water seepage and leakage, and effectively improves the connection stability and reliability of the floor 100s.

[0036] See Figure 2 and Figure 5 In one embodiment of the present invention, the bottom surface 51 is recessed and provided with a fastening groove 511, which is provided through the splicing side 70, and the fastening grooves 511 of two adjacent floor 100 are connected to each other; the floor 100 also includes a fastener 90, which is inserted into the fastening grooves 511 of at least two adjacent floor 100 to connect at least two adjacent floor 100.

[0037] During the splicing of two adjacent floorboards 100, the fastening grooves 511 of the adjacent floorboards 100 can be aligned and fitted with the splicing side 70 to form a channel. Fasteners 90 are inserted into this channel from the bottom of the floorboards 100. The two floorboards 100 are connected by the interlocking action of the fasteners 90 and the fastening grooves 511 of the adjacent floorboards 100, better limiting the relative separation of the two floorboards 100 and further improving the assembly stability of the floorboards 100. The inner diameter of the collar can be slightly smaller than the outer diameter of the channel to generate radial pressure through interference fit or elastic deformation, ensuring a tight contact between the collar and the inner wall of the fastening groove 511 of the adjacent floorboards 100. The circumferential constraint of the collar restricts the relative displacement of the adjacent floorboards 100 in the horizontal direction, while the axial constraint of the collar prevents the floorboards 100 from separating in the vertical direction. Furthermore, since the fastening grooves 511 are located on the bottom surface 51, the installation of the collar does not require flipping the floorboards 100; assembly can be completed directly from below after splicing, further improving the ease of splicing and assembling the floorboards 100.

[0038] By setting up mutually cooperating fastening grooves 511 and fasteners 90, a mechanical locking mechanism can be added to the interlocking action of the boss 71 and the slot 73, forming a double fixing effect and further improving the assembly stability and reliability of the floor 100. The cooperation between the fasteners 90 and the fastening grooves 511 can enhance the integrity between multiple floor 100s without increasing the complexity of the splicing operation, and better ensure the connection stability of the floor 100s under long-term use or external force.

[0039] See Figure 2 and Figure 5 In one embodiment of the present invention, the fastening groove 511 is provided at the corner of the bottom surface 51, the fastening groove 511 is provided in the form of an arc-shaped groove, and the fastener 90 is a collar, which is sleeved on the corner of the bottom surface 51 of at least two adjacent floor 100s.

[0040] In this embodiment, the corner of the bottom surface 51 can refer to the corner area formed by the intersection of the bottom plane of the floor 100 and the side of the floor 100. It can be implemented using a right angle or a rounded corner transition shape. This area has high structural strength and can provide a stable support foundation for the connecting components. The fastening groove 511 adopts an arc-shaped groove setting, which can refer to a curved and extended recessed structure. It can be implemented using a semi-circular, U-shaped, or parabolic cross-section shape. The curved inner wall of the arc-shaped groove is conducive to forming multi-point contact with the fastener 90, reducing local stress concentration and improving connection stability. By setting fastening grooves 511 at the corners of the bottom surface 51, multiple floorboards 100 can be connected to form a circular channel when they are spliced ​​together. At this time, by using a collar structure design for the fasteners 90, the collar can refer to a ring-shaped closed or open fastening component, which can be implemented in the form of an elastic rubber ring, metal clamp or plastic clamp. The ring-shaped fasteners 90 can be better inserted into the fastening grooves 511 of the multiple floorboards 100 and fit over the corners of the bottom surface 51 of the multiple floorboards 100, thereby constraining the corners of the bottom surface 51 of the multiple floorboards 100.

[0041] Specifically, during assembly, after the arc-shaped grooves at the corners of multiple adjacent floorboards 100 are aligned, a collar is inserted along the corner of the bottom surface 51 of the floorboard 100 and engaged in the fastening groove 511. Due to the curved surface characteristics of the arc-shaped grooves, the collar and the groove contact surface form a continuously distributed frictional force, while the ring structure itself generates a radial pressing force on the adjacent floorboards 100. When a single floorboard 100 deforms, the collar disperses the stress to the corner areas of the adjacent floorboards 100 through multi-point contact. The high strength characteristics of the corner areas can effectively resist deformation transmission, thereby maintaining the overall stability of the spliced ​​structure and better preventing the separation of multiple adjacent floorboards 100, further improving the splicing assembly stability of the floorboards 100.

[0042] See Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the length of the boss 71 is gradually reduced along the direction away from the splicing side 70, and the slot 73 is set to correspond to the shape of the boss 71.

[0043] In this embodiment, by making the length of the boss 71 gradually decrease in the direction away from the splicing side 70, the boss 71 can be made into a trapezoidal or wedge-shaped structure, so that at least one side of the boss 71 can form a guide slope that narrows from wide to narrow. At this time, the shape setting of the slot 73 corresponding to the boss 71 can mean that the inner wall contour of the slot 73 is completely matched with the reduced structure of the boss 71. This can be achieved by using a trapezoidal groove or a wedge-shaped groove, ensuring that the boss 71 and the inner wall of the slot 73 form a continuous contact surface during insertion.

[0044] Specifically, during the assembly process, the tapered structure of the boss 71 guides adjacent floorboards 100 to automatically align through the inclined surface. When the boss 71 is inserted into the slot 73, its two sides generate surface contact friction with the inner wall of the slot 73, preventing horizontal displacement. After assembly, the wide end of the boss 71 abuts against the wide end of the slot 73, forming a mechanical self-locking mechanism that restricts the vertical separation tendency of adjacent floorboards 100. Simultaneously, the matching shape of the slot 73 eliminates the assembly gap between the boss 71 and the slot 73, preventing loosening due to processing errors. This enhances the engagement force between the boss 71 and the slot 73, preventing adjacent floorboards 100 from separating and further improving the assembly stability and reliability of the floorboards 100. Furthermore, the tapered structure of the boss 71 utilizes the guide inclined surface to reduce assembly resistance, preventing the boss 71 from jamming against the inner wall of the slot 73 during insertion, allowing for easier insertion and effectively improving the installation efficiency of the floorboards 100.

[0045] Compared to existing technologies, current floor 100 splicing structures mostly use rectangular bosses 71 and rectangular slots 73 for mating, resulting in single-point or line contact after insertion. This makes them prone to localized wear or deformation and detachment due to stress concentration. This solution, however, optimizes the contact method to surface contact through the mating of tapered bosses 71 and matching slots 73, dispersing stress distribution. Simultaneously, the inclined self-locking effect enhances torsional resistance, effectively reducing the risk of detachment.

[0046] Furthermore, in one embodiment of this utility model, the opposite sides of the boss 71 are respectively set at an angle to the splicing side 70. Alternatively, one side of the boss 71 is set perpendicular to the splicing side 70, and the other opposite side of the boss 71 is set at an angle to the splicing side 70.

[0047] In this embodiment, the angle between the side of the boss 71 and the splicing side 70 can be achieved by using an inclination angle in the range of 5 to 15 degrees, such as 8 degrees or 12 degrees. Of course, angles of 30°, 45°, 60°, etc., can also be used. This application does not limit the included angle between the side of the boss 71 and the splicing side 70. By using an inclination angle design for the side of the boss 71, a progressive clamping force can be generated during the insertion process of the boss 71 and the slot 73. The geometric shape of the contact surface effectively changes the distribution of frictional resistance, making it easier for the boss 71 to be inserted into the slot 73 and achieving a tighter fit between the boss 71 and the slot 73. Specifically, when both sides of the boss 71 are inclined, the boss 71 can form a symmetrical wedge structure, which is beneficial for both inclined sides of the boss 71 to contact the inner wall of the slot 73 simultaneously during the insertion process, generating bidirectional compressive force and forming an interference fit between the boss 71 and the slot 73. The bidirectional inclination of the contact surface enables the splicing nodes to have deformation compensation capabilities in both the longitudinal and transverse directions. When the material of the floor 100 shrinks due to environmental factors or changes in external forces, the inclined surfaces on both sides can still maintain contact pressure, further improving the splicing and assembly stability and reliability of the floor 100.

[0048] Furthermore, when one side of the boss 71 is perpendicular to the splicing side 70, and the other opposite side is also perpendicular to the splicing side 70, the perpendicular setting can refer to the side wall surface forming a right angle with the splicing side 70, which can be achieved using a vertical processing technology. This vertical surface serves as a reference positioning surface, which can limit the lateral displacement of the boss 71 and provide supporting reaction force for the inclined side, achieving a more stable fit and connection between the boss 71 and the slot 73. Specifically, when the opposite sides of the boss 71 adopt a combination of single-sided vertical and single-sided inclined, the vertical surface can be used to complete the positioning in the initial stage of insertion, and the inclined surface can then generate continuous clamping force through inclined sliding. The vertical side can prevent lateral displacement, and the inclined side compensates for installation errors and eliminates gaps. The boss 71 with this structure can have a certain self-correcting function during splicing, allowing the inclined surface to guide the boss 71 to automatically adjust to the preset position during installation, further improving the assembly stability and reliability of the floor 100.

[0049] See Figure 3 In one embodiment of the present invention, the floor 100 includes a first sheet 10, a second sheet 30 and a third sheet 50 stacked in sequence. The surface of the first sheet 10 facing away from the second sheet 30 is the top surface 11, and the surface of the third sheet 50 facing away from the second sheet 30 is the bottom surface 51. The material of the second sheet 30 is polyurethane foam.

[0050] In this embodiment, the floor 100 is manufactured by laminating single-layer sheets, with the second sheet 30 in the middle layer made of polyurethane foam. This allows the floor 100 to form a structure with certain functions such as drop protection and shock absorption. Thus, by laying this floor 100 on the building floor, the elastic deformation of the second sheet 30 can absorb external pressure, enabling the floor 100 to buffer external forces. This helps reduce injuries from falls on the floor 100 and prevents breakage, effectively improving the practicality and reliability of the floor 100.

[0051] Furthermore, the synergistic effect of the three-layer structure allows the polyurethane foam in the middle layer to buffer stress through elastic deformation when the floor 100 is subjected to external pressure, reducing misalignment between the top surface 11 and the bottom surface 51 caused by rigid deformation. This better ensures the overall structural stability of the floor 100 and enables the stable splicing of multiple floor 100s. The first sheet 10 and the third sheet 50 can be made of materials with a certain degree of flexibility. The design allows the first sheet 10 and the second sheet 30 to have greater corrosion resistance, water resistance, fire resistance, wear resistance, and flexibility than the second sheet 30. This ensures that the first sheet 10 forming the top surface 11 and the second sheet 30 forming the bottom surface 51 can better protect the second sheet 30, achieving better drop resistance and shock absorption for the floor 100, further improving the overall structural stability and reliability of the floor 100.

[0052] Furthermore, in one embodiment of this utility model, the first sheet 10 is made of thermoplastic polyurethane elastomer; and / or, the third sheet 50 is made of thermoplastic polyurethane elastomer; and / or, the first sheet 10, the second sheet 30 and the third sheet 50 are integrally molded structures.

[0053] In this embodiment, thermoplastic polyurethane elastomer possesses excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, and has good processing performance. By using thermoplastic polyurethane elastomer to form the first sheet 10, the material properties of the first sheet 10 can be effectively improved, enabling the first sheet 10 to better withstand wear caused by stepping on it, dropping objects, etc. At the same time, it can make the top surface 11 of the floor 100 have better hydrophobicity, better preventing water from seeping into the interior of the floor 100 and affecting the second sheet 30, further improving the structural stability and reliability of the floor 100.

[0054] Similarly, by using thermoplastic polyurethane elastomer to form the third sheet 50, the material properties of the third sheet 50 can be effectively improved, so that the third sheet 50 can better cope with the mutual friction between the floor 100 and the building floor, ground and other surfaces. At the same time, it can make the bottom surface 51 of the floor 100 have better hydrophobicity, better preventing water from the bottom of the floor 100 from seeping into the interior of the floor 100 and affecting the second sheet 30, thereby further improving the structural stability and reliability of the floor 100.

[0055] Furthermore, the floor 100 is formed by casting the first sheet 10, the second sheet 30, and the third sheet 50 into a single mold. Utilizing the self-adhesive properties of the materials, the floor 100 is processed into a single structure. This allows for a tighter connection between the three sheets, effectively preventing peeling and further improving the overall structural stability and reliability of the floor 100. Of course, the floor 100 can also be manufactured using co-extrusion or other single-piece molding methods; this application does not limit this to any particular method, as long as it enables stable production of the floor 100.

[0056] See Figure 2 and Figure 5 In one embodiment of the present invention, the bottom surface 51 is provided with a drainage groove 513, which is provided through the opposite sides of the floor 100, and the drainage grooves 513 of two adjacent floor 100 are connected accordingly.

[0057] In this embodiment, the bottom surface 51 of the floor 100 can be formed into a drainage channel 513 using a grooving or molding process. This drainage channel 513 can extend through both sides of the floor 100, allowing water accumulated below the bottom surface 51 to flow into it and be discharged to the outside of the floor 100. This effectively reduces the amount of water accumulating below the bottom surface 51, lowering the risk of mold growth or warping due to moisture. Furthermore, by extending the drainage channel 513 through both sides of the floor 100, it ensures seamless connection between adjacent floorboards, creating a continuous drainage channel at the bottom of the floor 100 and further improving its practicality and reliability.

[0058] Specifically, when two adjacent floorboards 100 are connected via the splicing side 70, the openings of the drainage channels 513 on their bottom surfaces 51 are aligned, forming a flow path that runs through the splicing area. When liquid enters the splicing area, it can flow along the extension direction of the drainage channels 513 to the outside of the floorboards 100. Since the channels run through both sides of the floorboards 100, the liquid will not seep laterally or stagnate at the splicing seam, but will be guided to a predetermined direction for discharge, achieving directional drainage of liquid in the splicing area, preventing liquid from stagnating in the splicing seam for a long time, and further improving the structural stability and reliability of the floorboards 100.

[0059] See Figure 2 and Figure 5 In one embodiment of the present invention, the drainage trough 513 includes a first water trough 5131 and a second water trough 5133. The first water trough 5131 extends along a first direction, and the second water trough 5133 extends along a second direction. The first direction and the second direction intersect, and the first water trough 5131 and the second water trough 5133 are interconnected.

[0060] It should be noted that, as Figure 2 As shown in the reference coordinate system, the first direction and the second direction can be two intersecting directions on the plane where the floor 100 is located. At this time, the first water tank 5131 can be a tank structure that extends linearly along the first direction, or it can be a tank structure that extends in an arc or wave shape along the first direction; while the second water tank 5133 can be a tank structure that extends linearly along the second direction, or it can be a tank structure that extends in an arc or wave shape along the second direction. At this time, the first water tank 5131 and the second water tank 5133 can intersect and connect on the bottom surface 51 of the floor 100, so that the water accumulated at the bottom of the floor 100 can flow along the first water tank 5131 and the second water tank 5133, thereby achieving a better drainage effect and further improving the drainage effect of the water accumulated at the bottom of the floor 100.

[0061] The bottom surface 51 of the floor 100 forms a cross-drainage network through the mutually perpendicular first water channel 5131 and second water channel 5133. When water flows into the first water channel 5131, it is guided forward and backward through the longitudinal grooves; when water flows into the second water channel 5133, it is guided left and right through the transverse grooves. When adjacent floor 100s are joined, the first water channel 5131 connects with the first water channel 5131 of the adjacent floor 100 to form a continuous longitudinal drainage channel, and the second water channel 5133 connects with the second water channel 5133 of the adjacent floor 100 to form a continuous transverse drainage channel. The staggered connection of the two-way water channels allows the water flow to switch directions at the intersection, forming a multi-path drainage system. When a water channel in one direction is blocked by foreign objects, the water flow can be redirected to another water channel through the intersection to continue discharging, better avoiding water stagnation and further improving the practicality and reliability of the floor 100.

[0062] In one embodiment of this utility model, the bottom surface 51 is provided with anti-slip protrusions (not shown).

[0063] In this embodiment, the anti-slip protrusions refer to structures provided on the bottom surface 51 of the floor 100 to increase friction. These protrusions can be implemented using regularly arranged hemispheres, pyramids, or wavy patterns; of course, irregular shapes and patterns can also be used. This application does not limit the shape of the anti-slip protrusions. By utilizing the anti-slip structure, the surface roughness of the contact surface 51 of the bottom surface of the floor 100 can be increased, effectively suppressing the relative movement between the floor 100 and building floors, ground surfaces, etc., thus achieving more stable assembly and installation of the floor 100.

[0064] Specifically, the anti-slip protrusions, through their physical structure, can form multi-point support by contacting the ground. When the floor 100 is subjected to external forces or changes in environmental humidity, the friction generated by the protrusions can counteract the tendency of lateral displacement, preventing stress concentration caused by slippage in the splicing structure. Since the relative movement between the bottom surface 51 and the base surface is restricted, the insertion and engagement of the protrusions 71 and the slots 73 of adjacent floor 100 can be maintained stably, effectively avoiding the risk of loosening of adjacent floor 100, and further improving the practicality and structural reliability of the floor 100.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
