Description

Technical Field

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

[0002] Flooring is the surface layer of a building's ground or floor. In existing technology, adjacent floorboards are mostly connected together by mortise and tenon joints, adhesives, nailing (installing a joist on the ground first, and then fixing the floorboards to the joists with floor nails such as tack nails), or welding.

[0003] For example, patent document CN108505716A achieves the connection between adjacent floorboards by applying glue at the joints; patent document CN205502487U shows that the connection gaps between adjacent floorboards are brought together, and the rough surface layer of adjacent floorboards is connected to the same hook surface layer, thereby achieving the connection between two adjacent floorboards; patent document CN204531107U shows that the joints of adjacent flooring are welded together; and patent document CN205153460U shows that the metal welded honeycomb flooring includes a honeycomb panel and the panels at both ends of the honeycomb panel, with adjacent honeycomb panels welded together. However, in patent documents CN108505716A and CN205502487U, adjacent floorboards are glued together with Velcro, resulting in poor connection strength and easy warping or displacement under user foot traffic. In patent documents CN204531107U and CN205153460U, adjacent floorboards are welded together. When adjacent floorboards are welded together, the position of the floorboards needs to be constantly adjusted during the welding process. If a deviation in the position of the floorboards is found during welding, they need to be removed and re-welded, which leads to a longer installation cycle.

[0004] Therefore, how to shorten the floor installation cycle while ensuring strong connection stability between adjacent floorboards has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0015] Preferably, the corresponding welding areas of adjacent floor panels are made of the same material;

[0016] And / or, at least one of the two opposing welded areas of adjacent floor bodies is provided with a filler that can melt when the corresponding welded areas of the two adjacent floor bodies melt;

The side of the mother hook and loop fastener facing the daughter hook and loop fasteners is stepped, and the side of the daughter hook and loop fasteners facing the mother hook and loop fasteners in the connection area is also stepped.

The bottom ends of adjacent flooring bodies are quickly connected through corresponding connecting areas. The flooring body is provided with a welding area. Adjacent flooring bodies are also welded together through corresponding welding areas.

[0026] The quick-release connection can be a Velcro connection or a magnetic connection, which allows adjacent floor panels to be quickly connected together in the above manner to complete the initial fixation. This not only saves the operator from measuring the position of the floor with measuring equipment, but also saves the curing time required for welding and adhesive bonding, thereby shortening the installation cycle of the composite floor in this utility model and improving the installation efficiency. Furthermore, even if a deviation in the position of the floor panel is found before welding, the quick-release connection between the corresponding connection areas allows the adjacent floor panels to be quickly separated, adjusted, and then quickly reconnected. This saves the time spent by the operator in removing the welding rod and re-welding when adjusting the position of the floor after welding adjacent floor panels together, further shortening the installation cycle of the composite floor in this utility model.

[0027] Furthermore, in this utility model, adjacent welding areas can form welds, which means that at least one side of the weld is provided with a stress relief component. This allows the stress generated during the welding of adjacent floor bodies to be released through the stress relief component, reducing the problem of weld cracking, delamination or detachment due to unreleased stress. This ensures the stability of the connection between adjacent floor bodies, improves the integrity and strength of the composite floor, and reduces the probability of creep displacement and deformation of the composite floor due to load.

[0028] In summary, compared with existing flooring technologies, the composite flooring of this invention not only has a shorter installation cycle, but also provides a more robust connection stability between adjacent floorboards. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-4 As shown, this utility model discloses a composite floor, which includes several floor body 1s spliced ​​together. The bottom of the floor body 1 is provided with a connecting area and a welding area. The bottom ends of adjacent floor body 1s are quickly connected through corresponding connecting areas, and adjacent floor body 1s are also welded together through corresponding welding areas. The quick-release connection can be a Velcro connection or a magnetic connection, which allows adjacent floor body 1s to be quickly connected together in the above manner to complete the initial fixation. This not only saves the operator from measuring the floor position with measuring equipment, but also saves the curing time required for welding and adhesive bonding, thereby shortening the installation cycle of the composite floor in this utility model and improving the installation efficiency. Furthermore, even if a deviation in the position of the floor body 1 is found before welding, the quick-release connection between the corresponding connecting areas allows adjacent floor body 1s to be quickly separated, adjusted, and then quickly reconnected. This saves the time spent by the operator in removing the welding rod and re-welding when adjusting the floor position after welding adjacent floor bodies together, further shortening the installation cycle of the composite floor in this utility model.

[0038] Furthermore, in this invention, weld seams 2 can be formed between adjacent welding areas, which allows at least one side of the weld seam 2 to have stress-relieving components. This enables the stress generated during welding of adjacent floor body 1 to be released through the stress-relieving components, reducing the problem of weld seam 2 cracking, delamination, or detachment due to unreleased stress. This ensures the stability of the connection between adjacent floor body 1, improves the integrity and strength of the composite floor, and reduces the probability of creep displacement and deformation caused by load on the composite floor. In summary, compared with the flooring in the prior art, the composite flooring in this invention not only has a shorter installation cycle, but also has a more robust connection stability between adjacent floor body 1.

[0039] In this context, composite flooring can be understood as the overall structure formed by all the flooring pieces after the flooring in the area to be laid is completed. The main flooring piece 1 can be understood as the individual "small flooring pieces" that make up the composite flooring. The term "corresponding" in the connection area refers to the corresponding connection areas when two main flooring pieces 1 are joined together. For example, when the left and right main flooring pieces 1 are joined together, the connection area on the right side of the left main flooring piece 1 and the connection area on the left side of the right main flooring piece 1 are corresponding. Similarly, the meaning of "corresponding" in the corresponding welding area is the same as that in the corresponding connection area, and will not be elaborated further here. Weld 2 specifically refers to the weld 2 formed after two adjacent main flooring pieces 1 are welded together.

[0040] The bottom ends of adjacent floor panels 1 can be connected together through corresponding connecting areas. On opposite sides or adjacent sides of the bottom end of floor panel 1, one side protrudes outward (referred to as the protruding side), and the other side is recessed inward (referred to as the recessed side). The protruding and recessed sides match, meaning that when the bottom ends of adjacent floor panels 1 are connected through corresponding connecting areas, the opposite sides are the protruding and recessed sides, respectively. In this case, the sides abutting the lower region of the floor panel 1 can fit together without gaps. Alternatively, the corresponding connecting areas of adjacent floor panels 1 can be respectively located on the sides near the bottom end of the floor panel 1, eliminating the need for the protruding and recessed sides, and thus achieving connection between the bottom ends of adjacent floor panels 1 through the corresponding connecting areas. In this case, the two corresponding connecting areas of adjacent floor panels 1 include two magnets with opposite magnetic properties, or include a magnet and a ferromagnetic material such as iron or an iron-based alloy that can be attracted to the magnet. Alternatively, the two corresponding connecting areas of adjacent floor body 1 include two Velcro straps that can be glued together, one Velcro strap having a hook side and the other a rough side; or, the two corresponding connecting areas of adjacent floor body 1 include a locking block and a locking groove that can be snapped together.

[0041] Alternatively, the bottom ends of adjacent floor bodies 1 can be connected together by connectors. In this case, the connecting area is concave upwards, the connector matches the corresponding connecting area of ​​the adjacent floor body 1, and the bottom ends of the adjacent floor bodies 1 are respectively attached to the two sides of the connector. In this case, the two corresponding connecting areas of the adjacent floor bodies 1 can be magnets with the same magnetism, and the side of the connector facing the connecting area is a magnet with the opposite magnetism to the connecting area. Alternatively, one of the connecting area and the connector can be a magnet, and the other can be a ferromagnetic material that can be attracted to the magnet.

[0042] Specifically, when the bottom ends of adjacent floor panels 1, i.e., the ends closest to the ground, are fastened together using a connector, the composite flooring includes several first hook and loop fastener components. Each first hook and loop fastener component includes a female hook and loop fastener 3 located on the bottom surface of the floor panel 1 for laying in a designated area, i.e., the area where the flooring is to be laid. The female hook and loop fastener 3 is the connector, and several female hook and loop fasteners 4 located in the connection area. The side of the female hook and loop fastener 3 facing the female hook and loop fastener 4 is stepped, and the side of the female hook and loop fasteners 4 in the connection area facing the female hook and loop fastener 3 is also stepped. The female hook and loop fasteners 4 in the corresponding connection areas of two adjacent floor panels 1 are fastened together with the female hook and loop fastener 3 (fastening together means that one of the side of the female hook and loop fastener 4 facing the female hook and loop fastener 3 and the side of the female hook and loop fastener 3 facing the female hook and loop fastener 4 is hooked and loop fastener, and the hooked and loop fasteners can be fastened together). The stepped distribution means that the female hook and loop fastener 4 and the female hook and loop fastener 3 are distributed at different heights. This allows the meshing points, or adhesive points, of the hook and loop surfaces of the female hook and loop fastener 3 and the female hook and loop fastener 4 to be at different heights. This increases the contact area between the female hook and loop fastener 3 and the female hook and loop fastener 4, and reduces the problem of premature tearing of the hook and loop fasteners due to stress concentration caused by external shear stress or tensile stress at the connection between the female hook and loop fastener 4 and the female hook and loop fastener 3, or the female hook and loop fastener 3 falling off the ground and the female hook and loop fastener 4 falling off the floor body 1. This improves the connection strength between the female hook and loop fastener 4 and the female hook and loop fastener 3.

[0043] The sub-hook and loop fastener 4 can be fixed to the floor body 1 by adhesive or welding, and the female hook and loop fastener 3 can also be fixed to the ground by adhesive or welding. Alternatively, the female hook and loop fastener 3 can be placed directly on the ground and limited by the boundary line of the area to be laid. Furthermore, the stepped distribution of the sub-hook and loop fastener 4 and the female hook and loop fastener 3 can be achieved by adjusting the thickness of the sub-hook and loop fastener 4 or the female hook and loop fastener 3. Alternatively, stepped grooves distributed in the height direction can be set at the bottom of the floor body 1, and the sub-hook and loop fastener 4 can be applied along the stepped grooves. First, a support component with stepped steps, such as a support plate, is laid on the ground, and then the female hook and loop fastener 3 is laid along the stepped steps. It should be noted that the depth of the stepped groove should not be too deep to prevent unevenness on the surface of the floor body 1 when the sub-hook and loop fastener 4 and the female hook and loop fastener 3 are squeezed at the connection point; the depth of the stepped groove should also not be too shallow to prevent the sub-hook and loop fastener 4 and the female hook and loop fastener 3 from not being firmly connected together.

[0044] Furthermore, a rounded transition area is provided at the junction of the adhesive surfaces of the child hook and loop fastener 4 and the mother hook and loop fastener 3. This further avoids stress concentration, which would reduce the connection strength between the child hook and loop fastener 4 and the mother hook and loop fastener 3 and make them easy to separate.

[0045] Furthermore, a limiting area, and / or a waterproof area, or a drainage area, and / or a buffer zone can be provided on the bottom of the female hook and loop fastener 3, i.e., the side facing the ground. The limiting area specifically includes an adhesive layer located at the bottom of the female hook and loop fastener 3 that can bond to the ground. The adhesive layer can be glue. Alternatively, the limiting area may include anti-slip protrusions located at the bottom of the female hook and loop fastener 3 to increase the friction between the female hook and loop fastener 3 and the ground, reducing the displacement of the flooring body 1 on the ground. The drainage area may specifically include drainage holes that penetrate the female hook and loop fastener 3 and are spaced apart from the hook or textured surfaces on the female hook and loop fastener 3. When moisture reaches the female hook and loop fastener 3 through the seams between the flooring units or other channels 11, it can flow out through the drainage holes. Drainage holes connected to the drainage holes can be provided on the ground to drain moisture promptly. Drainage and waterproof zones can be set on the floor body 1 as needed. The waterproof zone can be a waterproof coating made of polyurethane waterproof paint or acrylic waterproof adhesive, or a waterproof film made of polyethylene (PE) or polypropylene (PVC). The buffer zone can be a rubber pad or foam made of ethylene-vinyl acetate copolymer set at the bottom of the female hook and loop fastener 3. The buffer zone isolates the female hook and loop fastener 3 from the ground, reduces friction damage caused by the female hook and loop fastener 3 sliding on the ground, and ensures a stable connection between the female hook and loop fastener 3 and the female hook and loop fastener 4.

[0046] The composite flooring includes several second hook-and-loop fastener components. Each second hook-and-loop fastener component includes a first hook-and-loop fastener 8 and a second hook-and-loop fastener 9 disposed on the flooring body 1. The first hook-and-loop fasteners 8 and 9 on the same flooring body 1 are arranged opposite to or adjacent to each other, and both are located between the top and bottom ends of the flooring body 1. The first hook-and-loop fasteners 8 and 9 can be interlocked, and adjacent flooring bodies 1 are connected together through corresponding first hook-and-loop fasteners 8 and 9. On opposite sides of the first hook-and-loop fasteners 8 and 9, one side is a rough surface and the other is a hook surface, which are then interlocked and bonded together. The first hook-and-loop fasteners 8 and 9 allow adjacent flooring bodies 1 to be bonded together, reducing or even completely eliminating gaps between adjacent floorboards, improving the aesthetics and overall strength of the composite flooring. The second hook-and-loop fastener components can be simultaneously disposed on corresponding positions on the flooring body 1 with the first hook-and-loop fastener components, or they can be disposed independently on the flooring body 1, allowing adjacent flooring bodies 1 to be directly connected through a connecting area, achieving a hook-and-loop adhesive connection.

[0047] Furthermore, the spacing between the stress relief component and the corresponding two welding zones to form the molten pool not only prevents direct contact between the molten pool and the stress relief component, thus avoiding the problem of molten metal directly entering the stress relief component during welding and becoming an integral part of it, causing the stress relief component to lose its stress relief function, but also plays a role in transmitting stress: when an external force is applied to the weld 2 area, the external force can be transmitted to the stress relief component through the area on the floor body 1 between the weld 2 and the stress relief component, thereby reducing the cracking of the weld 2 and the problem of reducing the connection strength between adjacent floor bodies 1.

[0048] The stress relief component includes a buffer section and / or a stress relief groove 12. The buffer section can be an elastic structure made of polyurethane elastomer (TPU) or silicone rubber. The deformation of the buffer section dissipates some of the welding stress, thereby reducing the problem of weld 2 cracking due to stress concentration at the weld seam 2, and thus reducing the connection strength between adjacent floor panels 1. And / or, the weld seam 2 can be wavy or serrated, which increases the contact interface between the groove and the substrate, extends the stress transmission path, and guides stress to disperse at multiple angles along the groove, reducing the problem of welding stress concentration in a certain direction. And / or, the stress relief groove 12 has a rounded transition area at its corners, which avoids abrupt changes in the shape of the stress relief groove 12 and reduces the problem of stress concentration in the stress relief groove 12. And / or, the stress relief groove 12 is set along the principal stress direction of the floor body 1, which allows external forces, such as the force of human stepping, to be released through the stress relief groove 12, preventing the stress on the floor body 1 from being unreleased and cracking; the principal stress direction can be determined by using finite element software such as ANSYS and ABAQUS to mesh the structure and load it, directly outputting the principal stress vector diagram, and then determining the principal stress direction of the floor body 1.

[0049] And / or, the cross-section of the stress relief groove 12 gradually increases from the direction close to the weld 2 to the direction away from the weld 2. This makes the elastic deformation space provided by the stress relief groove 12 gradually increase, so that the welding stress can gradually decrease with the increase of distance, avoid the problem of secondary stress concentration caused by stress abrupt change, and reduce the probability of cracking of weld 2.

[0050] And / or, the stress relief component includes a number of stress relief grooves 12 distributed in a grid pattern, which forms a crisscrossing groove network that can simultaneously capture and release stress in multiple directions, reducing the problem of stress relief grooves 12 that are only set in a single direction being "torn" by stress.

[0051] like Figure 2 , Figure 3 As shown, the welding area is located between the top and bottom of the floor body 1. A shielding member 13 is provided above the weld 2. The projection of the weld 2 on the top of the floor body 1 is located on the floor body 1 and / or the shielding member 13. The shielding member 13 shields the weld 2, so that after two adjacent floor bodies 1 are welded together through the corresponding welding areas, the weld 2 is not exposed on the surface of the floor body 1, thus ensuring the aesthetics of the floor body 1. This eliminates the step of repairing and covering the weld 2 after adjacent floor bodies 1 are welded together, further shortening the installation cycle and construction cost of the floor body 1.

[0052] Furthermore, the side and / or top of the floor body 1 are provided with channels 11 for welding equipment (specifically, a welding torch or other equipment capable of welding corresponding welding areas of adjacent floor bodies 1 together) to extend into and weld corresponding welding areas of adjacent floor bodies 1. This ensures the smooth realization of the function of welding corresponding welding areas of adjacent floor bodies 1 together. The shielding member 13 may specifically be a shielding plate or shielding piece integrally formed with or detachably connected to the floor body 1, such as... Figure 2 , Figure 3 As shown, when the welding area is located between the top and bottom of the floor body 1, the shielding member 13 can be an integrally formed structure with the floor body 1. In this case, the channel 11 is set on the side of the floor body 1. If the channel 11 on the side of the floor body 1 is insufficient for the welding equipment to extend or for the corresponding welding area to be fully welded, the side and top of the floor body 1 are provided with channels 11. The channel 11 of the floor body 1 can be understood as the gap between the opposite sides of the adjacent floor bodies 1 after the corresponding welding areas of the adjacent floor bodies 1 are joined together. This gap can be located above the welding area, such as at the top of the floor body 1. In this case, the shielding member 13 can be a shielding strip or a shielding piece. The shielding member 13 can be glued to the adjacent floor body 1, or slots and blocks can be set on the opposite sides of the shielding member 13 and the adjacent floor body 1 respectively. By snapping together with the adjacent floor body 1, the gap is filled and the weld 2 is shielded.

[0053] like Figure 2 , Figure 3 As shown, an isolation layer is provided between the welding area and the connection area. The stiffness of the isolation layer gradually decreases from the welding area to the connection area. The stiffness of the isolation layer is less than that of the welding area but greater than that of the connection area. This causes the stiffness of the floor body 1 to change gradually, so that the welding stress is buffered step by step during the transmission of the floor body 1. This avoids the problem of stress sudden change when the welding stress is directly transmitted from the high-stiffness area (welding area) to the low-stiffness area (connection area), which would cause cracking in the connection area. In turn, it improves the overall load-bearing capacity of the floor body 1. The isolation layer is specifically a structural layer made of polypropylene. In this case, the isolation layer has a porous structure, and the density of pores in the isolation layer gradually increases from the welding area to the connection area. Alternatively, the isolation layer includes a first isolation part 5, such as rigid polyvinyl chloride, a second isolation part 6, such as nylon, and a third isolation part 7, such as thermoplastic polyurethane, arranged sequentially from the welding area to the connection area. By arranging structural layers with gradually decreasing stiffness in the direction from the welding area to the connection area, a gradient change in the stiffness of the isolation layer is achieved. Alternatively, the isolation layer can be made of materials such as polyurethane or epoxy resin, and metal powder or glass fiber can be added to the side of the isolation layer near the welding area, thereby achieving a gradient change in the stiffness of the isolation layer on the side of the isolation layer near the connection area.

[0054] Furthermore, this invention includes a heat insulation layer between the connection area and the welding area. The heat insulation layer is located on the side of the isolation layer furthest from the connection area, and its stiffness is greater than that of the maximum stiffness region of the isolation layer. This heat insulation layer reduces or even blocks the transfer of heat generated during welding from the welding area to the connection area, preventing structural deformation and damage in the connection area, thus ensuring the effectiveness of the structural connection. Specifically, the heat insulation layer can be made of materials with heat insulation properties such as alumina, silicon carbide, or silicon nitride. The side of the floor body 1 has heat dissipation holes that are arranged to avoid interference with the heat insulation layer. This avoidance arrangement means that both the heat insulation layer and the heat dissipation holes can function without interfering with each other. This not only allows heat accumulated in the floor body 1 to dissipate through the heat dissipation holes but also ensures that the function of the heat insulation layer is not affected, improving the heat dissipation performance of the floor body 1.

[0055] Furthermore, the adjacent floor body 1 specifically refers to the corresponding welding areas of adjacent floor body 1 being made of the same material. This allows both welding areas to reach a molten state simultaneously during welding, thus avoiding the defect of one welding area overheating and burning through while the other welding area fails to fuse due to different material melting points. And / or, at least one of the two opposing welding areas of adjacent floor body 1 is provided with a filler 10, which can melt when the opposing welding areas of the two adjacent floor body 1 melt. This allows more material to fill the cracks inside the weld 2, thereby improving the weld 2's formation effect and reducing weld 2 cracking. The filler 10 being made of the same material as the welding area reduces the violent metallurgical reaction caused by the introduction of heterogeneous filler materials, suppressing the generation of cracks in the weld 2. And / or, the filler 10 is located in the molten pool formed when welding two opposite welding zones, and / or, the bottom of the filler 10 is located in the molten pool formed after welding two corresponding welding zones. The bottom of the molten pool is a high-incidence area for weld cracks 2. The filler 10 is set in this way so that after melting, it can enter the bottom of the molten pool, increase the volume of the molten pool, prolong the high-temperature residence time, promote gas escape, reduce the floating of porosity and inclusions, and thus reduce the generation of weld cracks 2. The filler 10 can be a protrusion or other structure set on the welding zone. The filler 10 can be a material such as metal that can fill cracks in weld 2. The size of the filler 10 needs to be large enough to fill cracks in weld 2.

[0056] The number and shape of the flooring body 1 can be adjusted according to the size and shape of the area where the flooring needs to be laid. The material of the flooring body 1 is not limited; it can be wood flooring, acrylic (PVC) flooring, or other types of flooring, as long as the flooring body 1 allows for the installation of the structures described above.

[0057] This utility model discloses multiple technical solutions, but does not provide any contrary technical teachings.

[0058] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
