Description

Technical Field

[0001] The present invention relates to the technical field of floor production, and in particular to a connection structure and a connection method of a composite floor. Background Art

[0002] Composite flooring is usually a type of flooring made of different materials. Most composite flooring in the existing technology is mainly composed of a floor profile and a composite polymer material layer fixed on the bearing surface of the floor profile. The composite polymer layer is set on the floor profile to enhance the wear resistance and anti-slip performance of the floor.

[0003] Since the composite polymer material layer is usually heated to a molten state and then laid on the floor profile to achieve the connection between the polymer material layer and the floor profile, it not only consumes a lot of energy and increases production costs, but also has a complicated process and low installation efficiency.

[0004] Based on these factors, Chinese utility model patent publication number CN216587510U discloses a snap-on alloy flooring system. The system comprises a flooring profile and a wear-resistant, non-slip layer disposed on the supporting surface of the flooring profile. A snap-on assembly is provided between the flooring profile and the wear-resistant, non-slip layer, through which the flooring profile is snap-connected to the wear-resistant, non-slip layer. Compared to existing technologies, this snap-on alloy flooring system utilizes a snap-on assembly to securely connect the flooring profile to the cushioning, wear-resistant layer, reducing energy consumption and costs. Furthermore, it is easier to construct and install, thereby improving production efficiency.

[0005] The above-mentioned alloy floor mainly connects the polymer material layer to the floor profile by physical clamping. During the installation and connection process, the floor profile is bound to deform to ensure that it fits tightly with the polymer material layer. Since the floor profile is a rigid part, a large external force needs to be applied to force it to deform and fit tightly with the polymer material layer. This not only increases the construction difficulty and reduces the assembly production efficiency, but also makes it difficult to accurately control the deformation degree of the floor profile. If the deformation degree is too small, the connection between it and the polymer material is likely to loosen, affecting the structural stability of the floor profile. If the deformation degree is too large, it is easy to cause structural damage to the floor profile, shorten the service life, and even lead to the production of defective products.

[0006] Therefore, it is necessary to improve the connection structure and connection method of the composite floor in the prior art. Summary of the Invention

[0007] The purpose of the present invention is to overcome the defects in the prior art and provide a connection structure and a connection method for composite floors that are easy to assemble, improve installation efficiency and ensure product quality.

[0008] In order to solve the above technical problems, the present invention provides a connection structure of a composite floor, comprising a floor profile and a flexible polymer material layer arranged on the bearing surface of the floor profile, wherein an assembly groove is provided on a side of the floor profile adjacent to the polymer material layer, and the polymer material layer includes a convex portion arranged in the assembly groove and extending along the length direction thereof, and the convex portion is provided with an assembly opening extending along the length direction thereof, and a rigid assembly part is provided in the assembly opening, and the convex portion is locked between the assembly part and the inner wall of the assembly groove.

[0012] Preferably, in order to facilitate the fixed connection between the polymer material layer and the floor profile, the assembly part is fixedly formed by a curable material injected into the assembly opening.

[0013] Preferably, in order to facilitate the injection of curable material into the assembly port so that the curable material is fixed and formed, and after the assembly part is formed, it cooperates with the inner wall of the assembly groove to lock the position of the protruding strip, the side of the polymer material layer facing away from the floor profile is provided with an injection port connected to the assembly port.

[0014] Preferably, in order to strengthen the connection between the polymer material layer and the floor profile while facilitating assembly and improving construction efficiency, the assembly groove is an assembly through groove, and the polymer material layer is provided with at least two, which are distributed along the length direction of the assembly groove and are sequentially fitted and connected. The two polymer material layer assembly ports corresponding to the two ends of the assembly through groove are arranged opposite to each other and are connected to each other, and at least one of the polymer material layers is provided with a material injection port connected to the assembly port on the side facing away from the floor profile.

[0015] Preferably, in order to facilitate the installation of the assembly part into the assembly opening, the assembly part includes two assembly shafts distributed along the length direction of the assembly through hole and detachably connected.

[0016] Preferably, in order to facilitate the quick and detachable connection of the two assembly shafts, the two assembly shafts are threadedly connected or snap-connected.

[0017] Preferably, in order to ensure the axial and radial locking connection between the assembly part and the convex strip part and strengthen the connection between the polymer material layer and the floor profile, the two assembly shafts are each provided with a positioning piece abutting against the end of the assembly groove at one end away from the connection between the two.

[0018] Preferably, in order to facilitate the production of the floor profile and strengthen the connection between the polymer material layer and the floor profile by increasing the contact area between the convex strip and the floor profile, the assembly groove is an assembly through groove extending along the length direction of the floor profile.

[0019] Preferably, in order to further strengthen the connection between the floor profile and the polymer material layer, at least two assembly grooves are provided.

[0020] Preferably, in order to improve the construction efficiency while strengthening the connection strength between the polymer material layer and the floor profile, there are two assembly grooves distributed side by side, and the two assembly grooves correspond to the two side edges of the polymer material layer in the length direction and are arranged closely.

The installation is convenient and the assembly efficiency is improved while ensuring the assembly quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0052] Example 1

[0053] like Figure 1-Figure 3As shown, the connection structure of the composite floor of Example 1 includes a floor profile 100, which is an alloy floor profile. The floor profile 100 is provided with assembly grooves 300 extending along its width direction. There are three assembly grooves 300 distributed side by side, and the notches of the assembly grooves 300 are flush with the bearing surface of the floor profile 100. The floor profile 100 is provided with a polymer material layer 200 covering its bearing surface. The horizontal projection of the polymer material layer 200 coincides with the horizontal projection of the bearing surface of the floor profile 100. The polymer material layer 200 is a flexible layer, and its main material is rubber. The bottom of the polymer material layer 200 is provided with three pairs of ridges 400 corresponding to the assembly grooves 300. The three pairs of ridges 400 are arranged in the assembly grooves 300 in a one-to-one manner. Each pair of ridges 400 is provided with two ridges 400. The two ridges 400 are flush with the two sides of the polymer material layer 200. The cross section of the ridge 400 is a U-shaped opening downward, so that the ridge 400 has a U-shaped assembly opening 401. The assembly opening 401 is provided with a length direction consistent with the length direction of the ridge 400. The rigid assembly part 500 is an alloy assembly shaft. The assembly part 500 is inserted into the U-shaped assembly opening 401 of the protruding portion 400 of the flexible polymer material layer 200, so that the circumferential outer edge of the assembly part 500 is tightly fitted with the inner side wall of the assembly opening 401. At the same time, the outer side wall of the protruding portion 400, which was originally clearance-matched with the assembly groove 300, expands outward to tightly fit on the inner wall of the assembly groove 300, that is, the protruding portion 400 is locked between the assembly part 500 and the inner wall of the assembly groove 300.

[0054] When connecting the floor profile 100 and the flexible polymer material layer 200, the composite floor connection structure of this embodiment covers the polymer material layer 200 on the bearing surface of the floor profile 100, and the flexible protrusion 400 of the polymer material layer 200 is installed in the assembly groove 300 of the floor profile 100 (when producing the floor profile 100 and the polymer material layer 200, ensure that the size of the protrusion 400 is smaller than or equal to the internal space size of the assembly groove 300 to facilitate the installation of the protrusion 400 in the assembly groove 300). Then, the protrusion 400 is inserted into the assembly opening 401 of the protrusion 400 along the length direction of the assembly groove 300. In its natural state, the cross-sectional dimensions of the assembly opening 401 are smaller than those of the assembly part 500. During the insertion of the ridge portion 400, the circumferential outer edge of the assembly part 500 fits tightly against the inner wall of the U-shaped assembly opening 401. At the same time, due to the flexible nature of the ridge portion 400, the outer side wall of the assembly opening 401 expands outward until it fits tightly against the inner wall of the assembly groove 300. Finally, the assembly part 500 presses the ridge portion 400 outward, while the inner wall of the assembly groove 300 presses the ridge portion 400 inward, that is, the flexible ridge portion 400 is locked between the rigid assembly part 500 and the rigid alloy floor, thereby fixing the flexible polymer material layer 200 on the floor profile 100.

[0055] Compared with the connection structure and connection method in the prior art in which external force is applied to the floor profile to enable it to be clamped with the polymer material layer, in this embodiment, an assembly opening 401 is opened on the convex portion 400 that is clearance-matched with the assembly groove 300, and a rigid assembly part 500 is inserted into the assembly opening 401, so that the flexible convex portion 400 is deformed, and finally the convex portion 400 is locked between the assembly part 500 and the inner wall of the assembly groove 300. This method relies on squeezing and deforming the flexible convex portion 400 to achieve a composite connection between the polymer material layer 200 and the floor profile 100, avoiding applying external force to the floor profile 100 to change its shape, thereby preventing the service life of the floor profile 100 from being shortened and the production of defective products. In addition, since the composite connection is achieved by squeezing the flexible convex portion 400, the operation is more convenient, ensuring the strength of the composite connection while facilitating rapid assembly, reducing assembly difficulty, improving work efficiency, and ensuring assembly quality.

[0056] It should be noted that, in this embodiment, the polymer material layer 200 uses rubber as the flexible elastomeric material, mainly utilizing its deformable characteristics, and inserting a rigid assembly part 500 into the assembly opening 401 of the convex portion 400, so that the convex portion 400 can be deformed by its own flexibility to lock the convex portion 400 between the assembly part 500 and the inner wall of the assembly groove 300. Therefore, as an alternative to achieve similar effects, the polymer material layer 200 can also use silicone, elastic plastic, and other new elastomeric materials.

[0057] The method for connecting the composite floor in this embodiment mainly includes the following steps:

[0058] S100. Prepare a floor profile 100 having an assembly groove 300 on its outer surface and a polymer material layer 200 having a ridge 400 on its bottom surface. Three assembly grooves 300 and three ridges 400 are provided, one corresponding to each other and arranged side by side along the length of the floor profile 100. The ridges 400 have a U-shaped cross-section, forming a U-shaped assembly opening 401. The ridges 400 can be received in the assembly grooves 300.

[0059] S200, covering the polymer material layer 200 on the bearing surface of the floor profile 100, while accommodating the convex strip 400 in the assembly groove 300, with the convex strip 400 and the assembly groove 300 being loosely fitted;

[0060] S300, insert the assembly part 500 into the assembly opening 401, so that the protrusion part 400 is deformed, and the circumferential outer edge of the protrusion part 400 expands outward to fit with the inner wall of the assembly groove 300, so that the protrusion part 400 is locked between the assembly part 500 and the inner wall of the assembly groove 300.

[0061] The preparation of the floor profile 100 having the assembly groove 300 on the outer surface in the above step S100 mainly includes the following steps:

[0062] S101, processing and producing floor profile 100 and long strip assembly groove 300;

[0063] S102, processing the floor profile 100 so that its bearing surface has three openings distributed side by side and extending to its sides at both ends, and the size of the openings is the same as the size of the assembly groove 300;

[0064] S103 , aligning the two ends of the assembly groove 300 with the two ends of the opening, and then welding and fixing the assembly groove 300 to the floor profile 100 .

[0065] In order to strengthen the composite connection strength, the inner wall cross-section of the assembly groove 300 is in the shape of an arc with a central angle greater than 180°. With the above design, when the assembly part 500 is inserted into the assembly opening 401, the deformed ridge portion 400 is locked in the assembly groove 300, which can prevent the ridge portion 400 from radially detaching from the assembly groove 300 along the assembly groove 300. Of course, the assembly groove 300 can also be other shapes, such as a dovetail shape, a T shape, an inverted trapezoidal shape, etc.

[0066] Example 2

[0067] like Figure 4-Figure 6 As shown, the connection structure of the composite floor of Example 2 is based on Example 1, but differs in that two assembly grooves 300 are integrally formed on the floor profile 100 and are distributed side by side, extending parallel to the length direction of the floor profile 100. The assembly grooves 300 are through-grooved and are respectively arranged adjacent to the two side surfaces of the floor profile 100; four ridges 400 are provided, two ridges 400 are provided at both ends of the polymer material layer 200, and the assembly openings 401 on the ridges 400 are assembly blind holes. The assembly blind holes at both ends of the polymer material layer 200 are arranged back to back, and two assembly parts 500 are plugged in each assembly blind hole. The assembly parts 500 are assembly rods extending along the length direction of the ridges 400, and the ridges 400 are locked between the assembly rods and the inner wall of the assembly groove 300.

[0068] In this embodiment, since the mounting groove 300 is integrally formed on the floor profile 100, when preparing a floor profile 100 with the mounting groove 300 on its outer surface, there is no need to intentionally drill holes in the floor profile 100 and then weld the mounting groove 300 to the floor profile 100, thereby improving production efficiency. In this embodiment, the mounting opening 401 of the protruding strip 400 is a blind mounting hole. Inserting a rod-shaped mounting member 500 into the blind mounting hole similarly deforms the protruding strip 400 to lockably fit the mounting groove 300, thereby achieving a quick and convenient composite connection between the floor profile 100 and the flexible polymer material layer.

[0069] Example 3

[0070] like Figure 7 and Figure 8 As shown, the connection structure of the composite floor of Example 3 is based on Example 2, except that the two ends of the protruding strip 400 extend to be flush with the two ends of the polymer material layer 200, the assembly opening 401 is an assembly through hole provided on the protruding strip 400 and extending along its length, the assembly part 500 is an assembly shaft with two ends flush with the two ends of the assembly through hole, and the floor profile 100, the assembly groove 300, the polymer material layer 200, the assembly opening 401 and the assembly part 500 are of the same length.

[0071] In this embodiment, the lengths of the ridge portion 400, the assembly opening 401, and the assembly part 500 are increased, so that when the locking connection is made, the contact area between the inner wall of the assembly opening 401 and the assembly part 500 and the contact area between the circumferential outer edge of the ridge portion 400 and the assembly groove 300 are increased, thereby reinforcing the connection strength of the assembly part 500, the ridge portion 400, and the assembly groove 300, and further strengthening the locking connection strength between the polymer material layer 200 and the assembly groove 300.

[0072] In addition, since the assembly opening 401 is an assembly through groove, when inserting the assembly part 500 into the assembly opening 401 , it can be inserted from any end, thereby achieving a firm composite connection between the floor profile 100 and the polymer material layer 200 .

[0073] Example 4

[0074] like Figure 9 and Figure 10 As shown, the connection structure of the composite floor of Example 4 is based on Example 5, with the difference that the assembly part 500 includes two assembly shafts 501 connected by threads, and the two assembly shafts 501 are respectively arranged at both ends of the assembly opening 401.

[0075] The assembly member 500 of this embodiment comprises two threadedly connected assembly shafts 501. During assembly, the two assembly shafts 501 are inserted into the assembly opening 401 from either end and then rotated relative to each other to achieve connection. This connection structure, in which the assembly shafts 501 are inserted from both ends of the assembly opening 401, reduces insertion depth and resistance, facilitating assembly. The two assembly shafts 501 are then threadedly connected to prevent separation. The threaded assembly shafts 501 expand the flexible ridges 400 outward, engaging with the assembly grooves 300 to achieve connection between the polymer material layer 200 and the floor profile 100.

[0076] Example 5

[0077] like Figure 11-Figure 15As shown, the connection structure of the composite floor of Example 5 is based on Example 4, with the difference that the assembly part 500 includes two assembly shafts 501 that are snap-fitted. Among the two assembly shafts 501 of the assembly part 500, a hook 700 is fixed on one of the assembly shafts 501, and a bayonet 800 is provided on the other assembly shaft 501. A snap ring 801 is provided on the circumferential inner wall of the bayonet 800, and the hook head of the hook 700 hooks the snap ring 801.

[0078] The assembly part 500 of this embodiment is formed by connecting two assembly shafts 501 that are snap-fitted together by a bayonet 800 and a hook 700. During assembly, the two assembly shafts 501 are respectively inserted into the two openings of the assembly port 401. The connection between the two assembly shafts 501 can be achieved by docking the hook 700 and the bayonet 800. There is no need to insert and then dock by rotation, which makes the operation more convenient.

[0079] A positioning piece 600 is provided at one end of the two assembly shafts 501 away from the connection between the two. The positioning piece 600 is a positioning rod, and its two ends are respectively fixedly connected to the assembly shafts 501 of the two assembly parts 500 at the end of the floor profile 100, so that the positioning piece 600 and the two assembly shafts 501 are integrally formed into a U-shaped structure, and the positioning piece 600 abuts against the end of the assembly groove 300.

[0080] After adopting the above structure, the assembly shafts 501 in the two assembly parts 500 at the ends of the floor profile 100 are fixedly connected by the positioning parts 600. Therefore, during actual construction, the assembly shafts 501 in the two assembly parts 500 are moved synchronously by the positioning parts 600, thereby realizing the synchronous assembly and molding of the two assembly parts 500, thereby improving work efficiency. Moreover, the positioning parts 600 abut against the ends of the assembly grooves 300 to position the insertion depth of the assembly shaft 501. After the two assembly parts 500 are formed, the two assembly parts 500 are finally fixedly connected by the two positioning parts 600 to form a closed loop frame. The two inner side walls of the closed loop frame abut against the two ends of the assembly grooves 300 on the floor profile 100. In this way, not only can the protruding strip part 400 be locked between the assembly shaft 501 and the assembly groove 300, but also the assembly shaft 501 and the protruding strip part 400 can be prevented from sliding along the axial direction of the assembly groove 300. In this way, the connection strength between the polymer material layer 200 and the floor profile 100 is further strengthened.

[0081] Notches 301 are provided at both ends of the assembly groove 300, with the two openings of the notches 301 located on the outer and inner walls of the grooves 300, respectively. On the floor profile 100, the notches 301 of the two side-by-side assembly grooves 300 are positioned opposite each other. The notches 301 accommodate the end of the positioning member 600 connected to the assembly shaft 501, i.e., the positioning rod is located inside the notches 301. This structure, utilizing the notches in the assembly grooves 300, ensures that, after assembly, the horizontal projection of the positioning member 600 lies within the horizontal projection of the floor profile 100, preventing the positioning member 600 from protruding beyond the end of the floor profile 100. This further improves product quality and facilitates the neat installation of the laminate flooring.

[0082] Example 6

[0083] Not shown, the connection structure of the composite floor of Example 6 is based on Example 1, except that the assembly opening 401 is an assembly through hole, and the assembly part 500 is fixed and formed by the curable material injected into the assembly opening 401 .

[0084] In this embodiment, the assembly member 500 is formed by injecting a curable material into the assembly opening 401, forming a rigid and strong assembly member 500. The formed assembly member 500 engages with the inner wall of the assembly groove 300, locking the ridge 400, thereby fixing the flexible polymer material layer 200 to the floor profile 100, making operation more convenient. To further strengthen the connection between the polymer material layer 200 and the floor profile, a high-pressure device can be used to inject the curable material into the assembly opening 401 under high pressure to strengthen the structural strength of the formed assembly member 500 and enhance the connection between the floor profile 100 and the polymer material layer 200.

[0085] The curable material of this embodiment includes but is not limited to concrete slurry, curable composite materials, ultraviolet curing materials, etc.

[0086] Example 7

[0087] like Figure 16 and Figure 17 As shown, the connection structure of the composite floor of Example 7 is based on Example 6, with the difference that a material injection port 201 connected to the assembly port 401 is provided on the side of the polymer material layer 200 facing away from the floor profile 100, and four material injection ports 201 are provided, which are evenly spaced between the two ends of the polymer material layer 200 along the length direction of the convex portion 400.

[0088] By setting the injection port 201 at the top of the polymer material layer 200, it is convenient to inject the curable material into the assembly port 401 under high pressure. Since there are multiple injection ports 201, and they are evenly spaced between the two ends of the polymer material layer 200 along the length direction of the convex portion 400, when injecting material into the assembly port 401, the curable material can be injected under high pressure from different positions, so that the curable material injected into the assembly port 401 is evenly distributed. In this way, it is ensured that the assembly part 500 after curing and forming can apply a uniform force on the convex portion 400 along its length direction, ensuring that the force on all parts of the convex portion 400 is uniform, and after injection, part of the curable material is fixed and formed in the injection port 201, preventing axial sliding between the assembly part 500 and the convex portion 400, further strengthening the connection strength between the polymer material layer 200 and the floor profile.

[0089] Example 8

[0090] like Figures 18-22 As shown, the connection structure of the composite floor of Example 8 is based on Example 7, with the difference that three polymer material layers 200 are provided, distributed along the length direction of the floor profile 100 and sequentially fitted and connected, and the convex portions 400 of the three polymer material layers 200 are all provided with assembly openings 401, wherein the assembly openings 401 on the polymer material layers 200 located at both ends are assembly blind holes arranged opposite to each other, and the assembly opening 401 on the polymer material layer 200 located at the center is an assembly through hole, and its two ends are respectively connected to the above-mentioned two assembly blind holes, and the top surfaces of the three polymer material layers 200 are all provided with injection ports 201 connected to their assembly openings 401.

[0091] In this embodiment, three polymer material layers 200 are provided, and the assembly openings 401 on the three polymer material layers 200 are assembly blind holes provided at both ends and assembly through holes connected to the two assembly blind holes. Figure 18After being laid on the floor profile 100 in a manner as described above, limiting members (such as limiting splints, which abut against the ends of the polymer material layers 200 at the two ends away from the center position of the polymer material layers 200) can be set at both ends of the floor profile 100 to clamp the three polymer material layers 200 on the floor profile 100 to prevent the end polymer material layers 200 from sliding, and then the curable material is injected into the assembly opening 401 through the three injection ports 201. After the curable material is fixed and formed, not only can the convex portions 400 of the polymer material layers 200 be locked on the inner wall of the assembly groove 300, but the three polymer material layers 200 are also fixedly connected to prevent them from separating. In addition, since the assembly openings 401 on the polymer material layers 200 at the two ends are assembly blind holes, the curable material can be prevented from overflowing from the end positions of the floor profile 100 during the high-pressure injection process. In this way, the assembly efficiency is improved and the construction is convenient, and the quality of the product is further improved.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
