Description

Technical Field

[0001] This invention relates to the field of flooring technology, and particularly to a composite SPC floor and its installation and connection structure. Background Technology

[0002] SPC click-lock flooring is made by bonding a base layer, a PVC decorative layer, and a wear-resistant layer together in one step through high-temperature calendering, with the surface treated with embossing and UV processes. However, existing SPC flooring generally suffers from poor waterproofing at the bottom, allowing moisture to easily seep into the flooring and damage it, thus reducing its performance. Furthermore, the installation process involves splicing the floorboards together, requiring repeated hammering to join them, which increases the difficulty of installation, requires more manpower and resources, and reduces the overall quality of the installation. Summary of the Invention

[0003] The problem solved by this invention is to provide a composite SPC flooring and its installation connection structure. The bottom waterproof structure protects against moisture, and the corner structure at the joints prevents moisture from directly entering the flooring, improving its performance. Furthermore, the limiting structure allows for direct installation of two floorboards without constant hammering, enabling quick assembly and reducing manpower and material costs. It also provides auxiliary installation, increasing stability and preventing floorboard warping during installation, further enhancing the overall installation effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a composite SPC flooring, comprising an SPC substrate layer, a colored film layer, an ultra-wear-resistant layer, a UV layer, a moisture-proof layer, an environmentally friendly sound-absorbing pad, and a waterproof layer. The colored film layer is disposed on the top outer wall of the SPC substrate layer, the ultra-wear-resistant layer is disposed on the top outer wall of the colored film layer, the UV layer is disposed on the top outer wall of the ultra-wear-resistant layer, the moisture-proof layer is disposed on the bottom outer wall of the SPC substrate layer, the environmentally friendly sound-absorbing pad is disposed on the bottom outer wall of the moisture-proof layer, and the waterproof layer is disposed on the bottom outer wall of the environmentally friendly sound-absorbing pad.

[0005] Preferably, an installation connection structure for a composite SPC floor includes an SPC floor body, an installation component, a limiting component, and protrusions, as well as the composite SPC floor as described in the claims. The installation component is fixed on one inner wall of the SPC floor body, the limiting component is fixed on one inner wall of the SPC floor body, and protrusions are distributed and fixedly connected on the bottom outer wall of the SPC floor body.

[0006] Preferably, the installation assembly includes a first locking plate, a second locking plate, a limiting hole, a moving groove, a first guide hole, a first limiting rod, a connecting plate, and a first spring. The first locking plate is plastically fixed to one outer wall of the SPC floor body, and the second locking plate is plastically fixed to the other outer wall of the SPC floor body corresponding to the first locking plate. A moving groove is formed on one inner wall of the SPC floor body, and a first limiting rod is installed on one inner wall of the moving groove. First guide holes are formed on both inner walls of the moving groove corresponding to the first limiting rod. A limiting hole is formed on one inner wall of the second locking plate corresponding to the first limiting rod. A connecting plate is fixedly connected to one inner wall of the first limiting rod, and first springs are fixedly connected to both outer walls of the connecting plate.

[0007] Preferably, the limiting component includes a mounting groove, a second guide hole, a sliding groove, a movable plate, a second limiting rod, a second spring, a pad, and a sliding plate. A mounting groove is formed on one inner wall of the first engaging plate. A movable plate is mounted on one inner wall of the mounting groove. Second limiting rods are fixedly connected to one outer wall of the movable plate. Second guide holes are formed on one inner wall of the mounting groove corresponding to the second limiting rods. Second springs are fixedly connected to one outer wall of the movable plate, with the other end of the second spring fixedly attached to the inner wall of the mounting groove. A pad is mounted on one inner wall of the mounting groove, with one side of the pad adhering to the outer wall of the movable plate. A sliding plate is fixedly connected to one outer wall of the pad. A sliding groove is formed on one inner wall of the mounting groove corresponding to the sliding plate.

[0008] Preferably, the first locking plate and the second locking plate are L-shaped, and one side of the first locking plate and the second locking plate is provided with an arc angle.

[0009] Preferably, one side of the inner wall of the first spring is sleeved on the outer wall of the first limiting rod, and the other end of the first spring is fixed to the inner wall of the moving groove.

[0010] Preferably, the inner wall of one side of the second spring is sleeved on the outer wall of the second limiting rod, and the number of the second springs is five.

[0011] Preferably, one end of the second limiting rod passes through the inner wall of the limiting hole.

[0012] The beneficial effects of this invention are: the bottom waterproof structure can protect the bottom moisture, and the corner structure at the splicing point makes it difficult for moisture to directly enter the floor, thus improving the floor's performance.

[0013] The installation components allow for direct installation of two floorboards via a limiting structure, eliminating the need for constant hammering and enabling rapid assembly. This reduces manpower and material costs, and improves the installation effect of the floorboards.

[0014] The use of limiting components can assist in the installation of the floor, increase the stability of the installation, prevent the floor from warping during installation, and improve the installation effect. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] See Figure 1A composite SPC flooring includes an SPC substrate layer 01, a colored film layer 02, a super wear-resistant layer 03, a UV layer 04, a moisture-proof layer 05, an environmentally friendly sound-absorbing pad 06, and a waterproof layer 07. The colored film layer 02 is provided on the top outer wall of the SPC substrate layer 01, the super wear-resistant layer 03 is provided on the top outer wall of the colored film layer 02, the UV layer 04 is provided on the top outer wall of the super wear-resistant layer 03, the moisture-proof layer 05 is provided on the bottom outer wall of the SPC substrate layer 01, the environmentally friendly sound-absorbing pad 06 is provided on the bottom outer wall of the moisture-proof layer 05, and the waterproof layer 07 is provided on the bottom outer wall of the environmentally friendly sound-absorbing pad 06.

[0026] Working principle: The SPC substrate layer 01 supports the balance of the entire floorboard. The color film layer 02 changes the color of the SPC substrate layer 01, thus enabling the floorboard to have different colors. The ultra-wear-resistant layer 03 increases the wear resistance of the floorboard. The UV layer 04 increases the stain resistance and waterproof effect of the bottom surface. The moisture-proof layer 05 absorbs moisture inside the floorboard. The waterproof layer 07 waterproofs the bottom of the floorboard. Finally, the environmentally friendly sound-absorbing pad 06 provides sound insulation.

[0027] Example 2

[0028] See Figure 2 , Figure 3 and Figure 5 An installation connection structure for a composite SPC floor includes an SPC floor body 1, an installation component 2, a limiting component 3, and protrusions 4, as well as the composite SPC floor of claim 1. The installation component 2 is fixed on one inner wall of the SPC floor body 1, the limiting component 3 is fixed on one inner wall of the SPC floor body 1, and protrusions 4 are distributed and fixedly connected on the bottom outer wall of the SPC floor body 1.

[0029] The mounting assembly 2 includes a first locking plate 201, a second locking plate 202, a limiting hole 203, a moving groove 204, a first guide hole 205, a first limiting rod 206, a connecting plate 207, and a first spring 208. The first locking plate 201 is plastically fixed to one outer wall of the SPC floor body 1, and the second locking plate 202 is plastically fixed to the other outer wall of the SPC floor body 1 corresponding to the first locking plate 201. A moving groove 204 is formed on one inner wall of the SPC floor body 1, and a first limiting rod 206 is installed on one inner wall of the moving groove 204. First guide holes 205 are formed on both inner walls of the moving groove 204 corresponding to the first limiting rod 206. A limiting hole 203 is formed on one inner wall of the second locking plate 202 corresponding to the first limiting rod 206. The first limiting rod 206 has a first guide hole 205 on one inner wall. A connecting plate 207 is fixedly connected to the inner wall, and a first spring 208 is fixedly connected to the outer walls on both sides of the connecting plate 207. The first locking plate 201 and the second locking plate 202 are L-shaped, and one side of the first locking plate 201 and the second locking plate 202 is provided with an arc angle. The arc angle on the first locking plate 201 can be used to press the first limiting rod 206, so that the first limiting rod 206 can move along the first guide hole 205 in the moving groove 204. The inner wall of one side of the first spring 208 is sleeved on the outer wall of the first limiting rod 206, and the other end of the first spring 208 is fixed to the inner wall of the moving groove 204. When the two SPC floor bodies 1 need to be disassembled, the first limiting rod 206 is separated from the limiting hole 203 by the action of the first spring 208.

[0030] The first locking plate 201 on one SPC flooring body 1 is locked onto the second locking plate 202 on another SPC flooring body 1. The second locking plate 202 presses against the first limiting rod 206, causing the first limiting rod 206 to move along the first guide hole 205 in the moving groove 204. The first limiting rod 206 is then inserted into the limiting hole 203 at the first locking plate 201, thereby locking and fixing the two SPC flooring bodies 1 together. This also causes the first spring 208 on the connecting plate 207 to stretch or compress. When the two SPC flooring bodies 1 need to be disassembled, the first limiting rod 206 is separated from the limiting hole 203 by the action of the first spring 208 and then reset. The limiting structure allows the two floorings to be installed directly without constant hammering, thus quickly assembling the flooring, reducing manpower and material resources, and improving the installation effect of the flooring.

[0031] Example 3

[0032] See Figure 3 and Figure 6The limiting component 3 includes a mounting groove 301, a second guide hole 302, a sliding groove 303, a movable plate 304, a second limiting rod 305, a second spring 306, a pad 307, and a sliding plate 308. A mounting groove 301 is formed on one inner wall of the first engaging plate 201. A movable plate 304 is mounted on one inner wall of the mounting groove 301. Second limiting rods 305 are fixedly connected to one outer wall of the movable plate 304. Second guide holes 302 are formed on one inner wall of the mounting groove 301 corresponding to the second limiting rods 305. Second springs 306 are fixedly connected to one outer wall of the movable plate 304, with the other end of each spring fixed to the inner wall of the mounting groove 301. A pad 307 is mounted on one inner wall of the mounting groove 301. The pad 307 is attached to the outer wall of the movable plate 304 on one side, and a slide plate 308 is fixedly connected to the outer wall of the pad 307. A groove 303 is provided on the inner wall of the mounting groove 301 corresponding to the slide plate 308. The inner wall of the second spring 306 is sleeved on the outer wall of the second limiting rod 305, and there are five second springs 306. When the pad 307 is removed from the mounting groove 301, the second limiting rod 305 on the movable plate 304 is reset by the action of the second spring 306. One end of the second limiting rod 305 passes through the inner wall of the limiting hole 203. The second limiting rod 305 can be inserted into the limiting hole 203 along the second guide hole 302, thereby enabling the SPC floor body 1 to be auxiliaryly limited.

[0033] During installation, a pad 307 is inserted into the mounting groove 301, and a sliding plate 308 on the pad 307 moves along the sliding groove 303. The pad 307 moves the moving plate 304, and the second limiting rod 305 on the moving plate 304 is inserted into the limiting hole 203 along the second guide hole 302, thereby providing auxiliary positioning for the SPC floor body 1. When the two SPC floor bodies 1 need to be disassembled, the pad 307 is removed from the mounting groove 301. Under the action of the second spring 306, the second limiting rod 305 on the moving plate 304 is reset, thereby moving the second limiting rod 305 out of the limiting hole 203. This can assist in the installation of the floor, increase the stability of the installation, prevent the floor from warping during installation, and improve the installation effect of the floor.
