Description

Technical Field

[0001] The present application relates to the field of flooring and wall panels, and in particular to a floorboard, a wall panel, and an assembly method of the floorboard and the wall panel. Background Art

[0002] Floor blocks are plate-like pieces laid on the ground, especially indoor floors. According to the material of the floor blocks, they are mainly divided into wooden floors, marble floors, and ceramic tile floors.

[0003] Conventional wood flooring is the only type of flooring that can be installed with a floor clip structure. This eliminates the need for wet-construction methods like laying a cement filler layer on the ground. Instead, the wood flooring can be installed by simply joining the individual flooring pieces together using the floor clips on the sides. However, to ensure sufficient strength, the wood flooring must be sufficiently thick, consuming a significant amount of wood.

[0004] Due to material and process limitations, marble and ceramic tile floors cannot be installed with floor clips. Therefore, they must be secured to the ground using a cement mixture applied through a process, with no direct connection between the individual marble or ceramic tiles. This process is not only complex and time-consuming, but also relies entirely on the skill of the construction workers to ensure the precise placement of the tiles. Furthermore, marble and ceramic tile floors are difficult to dismantle and reuse.

[0005] Furthermore, the wall panels used for decorating the interior and exterior walls of buildings also have the above-mentioned problems.

[0006] Based on the above reasons, the applicant initially thought of compounding marble slabs, ceramic tile slabs or thin wood boards on a base plate that is easy to shape or connect with locks, and using the locks on the base plate to connect the local blocks or wall panels to each other to form a floor or wall system. This not only saves the amount of wood, but also realizes the fully dry construction of marble, ceramic tile floors or wall panels.

[0007] However, how to precisely laminate the marble slabs, ceramic tile slabs or thin wood boards used as finishing layers at the ideal position on the substrate surface to ensure that the finishing layer and the substrate on each floor block or wall panel have exactly the same relative position is a question that the applicant has been considering.

[0008] This application arises from this. Summary of the Invention

[0009] The technical problem to be solved by the present application is: in response to the above problems, a method for assembling floor blocks, wall panels and floor blocks and wall panels is proposed, which cleverly installs a precisely positioned locking structure on the side of floor blocks or wall panels of various materials, so that floor blocks or wall panels of various materials can be neatly paved and connected by relying on a fully dry construction method.

[0027] A groove is formed at the lower portion of the side of the finishing layer, which is inwardly recessed and has a notch extending to the lower surface of the finishing layer. The upper portion of the second positioning protrusion extends into the groove.

[0028] The second positioning protrusion is a linearly extending strip-shaped protrusion, and the length side of the second positioning protrusion abuts against the side edge of the finishing layer in the horizontal direction;

[0029] The corrugated substrate is a polygonal plate formed by at least three straight side edges, and each of the straight side edges is fixed with a buckle;

[0031] The top of the second positioning protrusion is bent inward and bites into the side edge of the finishing layer.

[0032] The corrugated base plate is a rectangular plate formed by four straight side edges. The two clips arranged at right angles and welded together at one end are respectively embedded in the two straight side edges of the corrugated base plate.

[0033] The corrugated substrate is a rectangular plate formed by four straight side edges, each of the straight side edges is embedded with a buckle, each of the buckles is composed of a first buckle segment and a second buckle segment, and the first buckle segment and the second buckle segment are respectively provided with the positioning protrusion, the first buckle segment of each buckle is arranged at a right angle to the second buckle segment of the corresponding other buckle and one end is welded and fixed, the second buckle segment of each buckle is arranged at a right angle to the first buckle segment of the corresponding other buckle and one end is welded and fixed, and the first buckle segment and the second buckle segment, which are welded together at one end and arranged at a right angle, are respectively embedded in the two straight side positions of the corrugated substrate

[0034] The corrugated substrate is a polygonal plate formed by at least three straight side edges, and each of the straight side edges is fixed with a buckle;

[0044] This application can achieve the following beneficial effects:

[0045] 1. The wear-resistant and beautiful marble, ceramic tile or wooden finishing layer is combined with the corrugated board with excellent compressive and bending resistance and high structural strength. The corrugated base plate adopts a special structure to cleverly connect the buckles to make it into floor blocks or wall panels with buckles. It not only makes up for the shortcomings of traditional wooden, marble or ceramic tile floor and wall panels with low structural strength and easy damage, but also realizes the rapid splicing of blocks or wall panels from all places.

[0046] 2. Positioning protrusions are set on the clips, so that each clip on each floor block or wall panel and the corrugation basically have a uniform and precise assembly position, which improves the uniformity of the shape and structure of each block or wall panel, and thus enables the blocks or wall panels to be smoothly docked. After the docking is completed, the gaps between adjacent floor blocks or wall panels are neatly and uniformly sized.

[0047] 3. The positioning protrusion on the buckle can be designed to be higher, which can not only locate the basic assembly position of the buckle and the corrugated board, but also locate the installation position of the upper finishing layer.

[0048] 4. Arrange the two clips or clip segments at right angles in advance and weld one end to form an L-shaped structural member. Then, embed the two side arms with positioning protrusions on the L-shaped structural member into the clip embedding gaps at the two straight side edges of the corrugated substrate. This not only locates the embedding depth of the clip in the straight side of the corrugated substrate, but also locates the position of the clip in the length direction of the straight side of the corrugated substrate.

DETAILED DESCRIPTION

[0076] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0077] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meanings understood by persons having ordinary skills in the field to which this application belongs. The words "a" or "an" and the like used in the patent application specification and claims of this application do not indicate a limitation on quantity, but rather indicate the presence of at least one.

[0078] The term "fixed connection" used in the patent application specification and claims of this application does not include an integral connection.

[0079] In the description of the specification and claims of this application, the terms "upper", "lower", "horizontal", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting this application.

[0080] Now, embodiments of the present application are described with reference to the accompanying drawings.

[0081] Example 1:

[0082] Figures 1 to 6 A preferred embodiment of the floorboards of the present application is shown. Similar to most existing floorboards, the outer contour of the floorboard is roughly rectangular, and each side thereof is provided with a clip 3 (commonly known as a floor clip) for connecting two adjacent floorboards together.

[0083] Unlike traditional floorboards, the floorboards of this embodiment primarily consist of a lower corrugated baseboard 1 and an upper finishing layer 2. Both the lower corrugated baseboard 1 and the upper finishing layer 2 are rectangular structures, each having two parallel long sides and two parallel short sides. Furthermore, each side of the corrugated baseboard 1 is fixedly connected to a snap 3, for a total of four snaps 3: two male snaps 3a and two female snaps 3b. Specifically, one long side and one short side of the corrugated baseboard 1 are each fixedly connected to a male snap 3a, while the other long side and the other short side of the corrugated baseboard 1 are each fixedly connected to a female snap 3b. Clearly, the snaps in this embodiment are not integral to the floorboard structure; rather, they are separate, interconnected components. The male snap 3a and female snap 3b on the floorboards are compatible. "Compatible" means that the male snap 3a and female snap 3b, removed from the corrugated baseboard 1, can engage with each other. In this way, multiple floorboards can be connected to each other by means of male and female buckles that cooperate with each other to form a floor system installed on the ground, such as Figure 5 .

[0084] The two male and female buckles on a floorboard can have different structures, and the two female buckles can also have different structures. For example, the floorboard disclosed in Chinese invention patent publication number CN101910528B has male and female buckles on its two long sides that engage with each other in an angular flipping manner, while its two short sides have male and female buckles of another structure that engage with each other in a vertical displacement manner.

[0085] Similar to traditional corrugated boards, the corrugated substrate 1 of this embodiment also includes: an upper board 101, a lower board 102 arranged parallel to and below the upper board, and a corrugated core layer 103 fixedly connected between the upper board and the lower board.

[0086] Furthermore, the upper plate 101 is fixed to the upper surface of the corrugated core layer 103 by means of an adhesive (hot melt adhesive film), and the lower plate 102 is fixed to the lower surface of the corrugated core layer 103 by means of an adhesive (hot melt adhesive film). Of course, the upper and lower plates can also be fixed to the corrugated core layer by welding.

[0087] The finishing layer 2 is bonded to the upper surface of the upper plate 101 by means of an adhesive, thereby achieving a bond between the finishing layer 2 and the corrugated substrate 1. To enhance the vertical compression and impact resistance of the finishing layer 2 and prevent the finishing layer 2 from breaking when subjected to vertical loads or vertical impacts (especially when the finishing layer 2 is a marble slab or a ceramic tile slab), the adhesive used to bond the finishing layer 2 to the upper plate 101 is preferably continuous and dense, thereby forming a continuous and dense adhesive layer (not shown in the figure) between the finishing layer 2 and the upper plate 101.

[0088] The above-mentioned "continuous and dense adhesive layer" can be achieved by increasing the amount of adhesive used, or by sandwiching a hot melt adhesive film between the finishing layer 2 and the upper plate body 101, and first allowing the aforementioned hot melt adhesive film to melt at a high temperature, and then allowing the molten hot melt adhesive film to solidify at a low temperature.

[0089] Unlike conventional corrugated board, the area of ​​the corrugated core 103 in this embodiment of the corrugated substrate is smaller than that of the upper and lower panels 101, 102. Furthermore, each side edge of the corrugated core 103 lies inboard of the corresponding side edges of the upper and lower panels 101, 102. This creates a snap-fitting gap 1a around the corrugated core 103 between the upper and lower panels 101, 102. Each of the aforementioned snaps 3 is embedded in this snap-fitting gap 1a. Furthermore, the snap portions embedded in this gap 1a are welded to the upper and lower panels 101, 102.

[0090] It should be noted that the buckle 3 can also be welded to only one of the upper plate 101 or the lower plate 102. The advantage of this design is that it improves the assembly efficiency of the buckle and the corrugated substrate 1. However, the disadvantage is that the connection strength between the buckle and the corrugated substrate 1 is slightly weak.

[0091] In addition, adhesive may be coated on the buckle 3 , and the buckle portion embedded in the buckle installation gap 1 a may be bonded and fixed to the upper plate 101 and / or the lower plate 102 using the adhesive.

[0092] In this embodiment, each buckle is an integrally formed part and is made of aluminum profile. Of course, the buckle can also be made of other materials, such as an integrally formed plastic part.

[0093] In this embodiment, the shape of the corrugated substrate 1 is adapted to the shape of the floorboards and is also a long, rectangular board. Similar to most corrugated boards, the corrugated core layer 103 in this embodiment also has a wavy structure, with multiple alternating peaks and troughs. As we know, the bending strength of a long, rectangular board in the length direction is weaker than its bending strength in the width direction, while the bending strength of a wavy corrugated core layer in a direction perpendicular to the arrangement of the peaks and troughs is much higher than its bending strength in a direction parallel to the arrangement of the peaks and troughs. Based on this, in this embodiment, the peaks and troughs of the wavy corrugated core layer are alternately arranged along the width direction of the corrugated substrate 1, thereby significantly improving the bending resistance of the rectangular floorboards in the length direction.

[0094] As mentioned above, the upper plate 101 is bonded to the upper surface of the corrugated core layer 103 with an adhesive (hot-melt adhesive film), and the lower plate 102 is bonded to the lower surface of the corrugated core layer 103 with an adhesive (hot-melt adhesive film). Therefore, by simply controlling the bonding process when bonding the upper and lower plates and the intermediate corrugated core layer, each peak of the corrugated core layer can be bonded to the upper plate 101, and each trough can be bonded to the lower plate 102. This ensures that each peak and trough of the corrugated core layer is tightly bonded to the upper and lower plates, allowing the rectangular floorboard to withstand large bending torques in the width direction.

[0095] When the flooring is installed indoors (or outdoors), the upper surface of the finishing layer 2 is exposed to the environment and is walked on by people. Therefore, the finishing layer should not only have a decorative function but also good wear resistance. The finishing layer 2 is typically a marble slab, a ceramic tile, a wooden board, or a plastic board. In this embodiment, the finishing layer 2 is a wooden board, and the thickness of the board is only a few millimeters.

[0096] The corrugated substrate 1 is a corrugated aluminum sheet, with both the upper and lower panels 101, 102 being aluminum sheets, and the intermediate corrugated core 103 being aluminum corrugated. The finishing layer 2, as well as the upper and lower panels 101, 102, and corrugated core 103 of the corrugated substrate 1, can also be made of other materials. For example, the finishing layer 2 can be made of marble, ceramic tile, or plastic. The upper and lower panels 101, 102 can also be steel sheets, and the intermediate corrugated core 103 can be made of stainless steel, plastic, or fiberglass.

[0097] This embodiment uses corrugated aluminum sheet as the base of the floorboards, mainly based on the following two considerations:

[0098] 1. The production process of corrugated aluminum is mature, with low cost and light weight.

[0099] 2. The thermal conductivity of corrugated aluminum sheets is extremely high, and the floor panels can be used in floor heating systems to quickly conduct the heat from the heat source under the floor panels to the finishing layer 2, and then from the finishing layer 2 to the interior.

[0100] During the production process of this floorboard, when the clips 3 are inserted into the clip insertion gap 1a between the upper and lower panels, the insertion depth of the clips 3 is difficult to control. This results in inconsistent positions of the clips 3 on each floorboard. Consequently, when the floorboards are connected, the gaps between adjacent floorboards vary in size, affecting the aesthetics. In severe cases, the floorboards may even become incompatible with each other.

[0101] Based on this, in this embodiment, an upwardly protruding positioning protrusion 301 is provided on each buckle 3, and the side of the upper plate body 101 and the positioning protrusion 301 abut against each other in the horizontal direction (the positioning protrusion is arranged against the outer side of the corresponding side of the upper plate body).

[0102] During assembly, align the buckle 3 with the buckle installation gap 1a between the upper and lower plates and insert it inward. When the positioning protrusion 301 on the buckle 3 abuts against the corresponding side of the upper plate and cannot be inserted further, it means that the buckle 3 is installed in place.

[0103] Furthermore, the positioning protrusion 301 is a linearly extending strip protrusion, and the length side of the strip positioning protrusion abuts against the side edge of the upper plate 101 in the aforementioned horizontal direction. This can not only locate the embedding depth of the buckle 3, but also locate the embedding angle of the buckle 3 very accurately.

[0104] Reference Figure 1 and Figure 2 As shown, the positioning protrusions 301 on the two clips 3 (male clips) are higher than the upper surface of the upper plate 101, and the raised portions of the positioning protrusions 301 horizontally abut against the side edges of the finishing layer 2. This design is advantageous: when the clips 3 are assembled with the corrugated substrate 1, the positioning protrusions 301 of the two clips 3 protrude from the upper surface of the upper plate 101, thereby providing a positioning for the installation of the finishing layer 2.

[0105] If the side of the finishing layer 2 is a flat structure, the upper part of the positioning protrusion 301 completely rests on the outer side of the side of the finishing layer 2. After the panels are joined, there will be a large gap between the adjacent finishing layers 2, which is not only unsightly but also easily contaminated. In this embodiment, the lower part of the two sides of the finishing layer 2 is formed with an inwardly concave groove 202, and the notch extends to the lower surface of the finishing layer 2. The upper part of the positioning protrusion 301 extends into the aforementioned groove 202. Figure 1 and Figure 2 .

[0106] Refer again Figure 1 and Figure 2 As shown, if only the positioning protrusions 301 on two clips 3 are higher than the upper surface of the upper plate 101 to position the installation of the finishing layer 2, the positioning and installation of the finishing layer 2 will still not be accurate and quick. Therefore, this embodiment provides upwardly projecting second positioning protrusions 302 on the other two clips 3 (male clips) of the floorboard. The other side edges of the finishing layer 2 abut against these second positioning protrusions 302 in the horizontal direction. In this way, when the clips 3 are assembled with the corrugated substrate 1, the higher positioning protrusions 301 of two clips 3 and the second positioning protrusions 302 of the other two clips 3 form a groove-like structure. The finishing layer 2 can be aligned with the notch of the groove-like structure and inserted downward to complete the positioning and installation of the finishing layer 2.

[0107] In this embodiment, grooves 202 that are recessed inward and extend to the lower surface of the finishing layer 2 are also formed at the lower parts of the other two side edges of the finishing layer 2 , and the upper parts of the second positioning protrusions 302 extend into the grooves 202 .

[0108] In this embodiment, the second positioning protrusion 302 is also a linearly extending strip-shaped protrusion, and the length side of the second positioning protrusion 302 abuts against the side edge of the finishing layer 2 in the horizontal direction.

[0109] In addition, in order to more accurately position the assembly of the clip 3 and the corrugated substrate 1, this embodiment also provides a third positioning protrusion 303 protruding downward on each clip 3, and the side of the lower plate 102 and the third positioning protrusion 303 abut against each other in the horizontal direction.

[0110] Reference Figure 1 、 Figure 2 and Figure 4 As shown, the shape of the corrugated substrate 1 in this embodiment corresponds to the shape of the entire floor panel, and is also a rectangular plate surrounded by four straight side edges. As mentioned above, each side of the floor panel is provided with a clip 3, and each clip 3 is provided with a positioning protrusion 301 for locating its installation position. However, the positioning protrusion 301 of the clip 3 can only locate the embedding depth of the clip in the side position of the corrugated substrate 1, and cannot locate the position of the clip 3 along the length direction of the straight side of the corrugated substrate. However, as long as the length of the clip 3 is set to be less than the length of the straight side of the corrugated substrate, there will basically be no problem of the end of the clip 3 exceeding (extending) too much from the outside of the corrugated substrate during assembly. However, this embodiment provides a more clever way to solve the above problem: refer to Figure 4 and Figure 6 As shown, each clip 3 on each side of the corrugated substrate 1 is divided into two sections. Each clip 3 thus consists of a first clip segment 31 and a second clip segment 32, each of which is provided with the aforementioned positioning protrusion 301. Prior to assembly, the first clip segment 31 of each clip is arranged at a right angle (L-shaped) to the second clip segment 32 of the corresponding clip and welded together at one end. The second clip segment 32 of each clip is also arranged at a right angle (L-shaped) to the first clip segment 31 of the corresponding clip and welded together at one end. The first clip segment 31 and the second clip segment 32, each welded together at one end and arranged at a right angle, belonging to two different clips 3, are then installed in the clip installation gap 1a located on two straight sides of the corrugated substrate 1 (obviously, these two straight sides are perpendicular to each other) in the manner described above (i.e., the positioning protrusion 301 of each clip segment rests horizontally against the side of the upper plate 101). After assembly is completed, the positioning protrusions 301 on the first buckle segment 31 and the positioning protrusions 301 on the second buckle segment 32 respectively rest against the two vertical side edges of the upper plate of the corrugated substrate, which not only locates the embedding depth of each buckle segment, but also locates the position of each buckle segment in the length direction of the straight side edge of the corrugated substrate.

[0111] In addition, after one end of the first buckle segment 31 and the second buckle segment 32, which belong to two different buckles 3 and are distributed at right angles, are welded and fixed together, the connection stability of each buckle segment and the corrugated substrate 1 is improved, and the possibility of the side of the upper plate or lower plate flipping outward and warping due to the force applied to each buckle segment (buckle) is reduced.

[0112] After the assembly is completed, the first buckle section 31 and the second buckle section 32 belonging to the same buckle 3 do not need to be welded.

[0113] Obviously, we can just keep Figure 6 One of the L-shaped structural members is removed, and the remaining three are discarded. The only remaining L-shaped member has two sides each representing a floorboard, one male buckle and the other female buckle. The buckle 3 is now a single, integrated structure, no longer consisting of two segments. These two buckles 3 are respectively embedded in the buckle insertion gaps 1a located on the two linear sides of the corrugated substrate 1. This also determines both the embedding depth of the buckle within the linear side of the corrugated substrate and its position along the length of the linear side of the corrugated substrate.

[0114] Example 2:

[0115] Figure 7 and Figure 8 The second preferred embodiment of the floorboard of the present application is shown. The structure of the floorboard is basically the same as that of the floorboard of the first embodiment, with the main differences being:

[0116] All buckles 3 are female buckles 3b, and the positioning protrusion 301 of each buckle 3 protrudes from the upper surface of the upper plate 101 and abuts against the side of the finishing layer 2 in the horizontal direction. None of the buckles 3 are additionally provided with the second positioning protrusion 302 of the first embodiment.

[0117] Example 3:

[0118] Figure 9 and Figure 10 The third preferred embodiment of the floorboards of the present application is shown. The structure of the floorboards is basically the same as that of the floorboards in the first embodiment, with the main differences being:

[0119] All the buckles 3 are male buckles 3 a , and each buckle 3 includes a second positioning protrusion 302 that protrudes upward and abuts horizontally against the side edge of the finishing layer.

[0120] Typically, the floor panels of the third embodiment and the fourth embodiment need to be used together and connected to form a large-area floor system paved on the ground.

[0121] Example 4:

[0122] Figure 11 and Figure 12 The fourth preferred embodiment of the floorboards of the present application is shown. The structure of the floorboards is basically the same as that of the floorboards in the first embodiment, with the main differences being:

[0123] The tops of the positioning protrusions 301 that extend above the upper surface of the upper plate 101 are bent inward and bite into the side of the finishing layer 2, ensuring a more secure grip on the finishing layer 2. The tops of the second positioning protrusions 302 are also bent inward and bite into the side of the finishing layer 2. During production, a linear bite groove 201 can be pre-cut midway along the side of the finishing layer 2. The originally straight positioning protrusions 301 and second positioning protrusions 302 are then bent and snapped into these bite grooves.

[0124] Embodiment 5:

[0125] Figures 13 to 15 The fifth preferred embodiment of the floorboards of the present application is shown. The structure of the floorboards is basically the same as that of the floorboards in the first embodiment, with the main differences being:

[0126] The positioning protrusions 301 that are higher than the upper surface of the upper plate body 101 have a portion thereof that is higher than the upper surface of the upper plate body 101 and has a length edge facing the finishing layer 2 that is a bevel edge 301a with a top side away from the center of the finishing layer and a bottom side closer to the center of the finishing layer. The second positioning protrusions 302 that are higher than the upper surface of the upper plate body 101 and have a length edge facing the finishing layer 2 that is a second bevel edge 302a with a top side away from the center of the finishing layer and a bottom side closer to the center of the finishing layer.

[0127] In this way, the two bevel edges 301a and the two second bevel edges 302a together form a trumpet-shaped groove that is wider at the top and narrower at the bottom, which is very beneficial for the downward positioning and installation of the upper finishing layer 2.

[0128] Example 6:

[0139] The second positioning protrusion 302 on all the buckles 3 is higher than the upper surface of the upper plate 101, and the length side facing the finishing layer 2 is the second bevel edge 302a with the top side away from the center of the finishing layer and the bottom side close to the center of the finishing layer.

[0140] It should be noted that in some other embodiments of the present application, the floor panels can be made into other shapes, such as triangles, hexagons, sectors, or even various special shapes. Moreover, it is not necessary to provide the above-mentioned buckles 3 on every side of the floor panel; the buckles 3 can be provided on at least one side according to actual needs.

[0141] Embodiment 10:

[0142] Figure 24 A specific embodiment of the wall panel of the present application is shown. The wall panel has the same structure as the floor panel in the first embodiment. The only difference is that the wall panel is used as a wall panel in the present embodiment, while it is used as a floor panel in the first embodiment.

[0143] The wall panel can be fixed on the outer wall of a building as an outer wall panel, and can also be arranged on the inner wall of a building as an inner wall panel.

[0144] During installation, the wall panels with male and female clips on the side can be spliced ​​and fixed to each other. Each wall panel can be installed and positioned based on the previous wall panel, which not only facilitates the installation of the wall system, but also makes the formed wall system have good structural integrity and aesthetics.

[0145] The above are merely exemplary embodiments of the present application and are not intended to limit the scope of protection of the present application. The scope of protection of the present application is determined by the appended claims.
