A thermal insulation type modular wood-plastic composite floor and its manufacturing process

Abstract

This invention discloses an insulated modular wood-plastic composite flooring and its manufacturing process, belonging to the technical field of wood-plastic composite flooring. The insulated modular wood-plastic composite flooring and its manufacturing process include an outer composite wood-plastic board and an insulating pad. The insulating pad is installed below the outer composite wood-plastic board and above a multi-layered frame. The multi-layered frame includes a top axis strip and a bottom axis strip, with the top axis strip located above the bottom axis strip. The top and bottom axis strips intersect horizontally and vertically. To address the problem that the insulation board is located inside the flooring and lacks its own independent support structure, and that the flooring is subject to external pressure during use, which can lead to breakage or detachment of the internal insulation layer over time, the insulating pad separates the outer composite wood-plastic board from the installation surface. This prevents moisture from the ground from seeping into the interior of the outer composite wood-plastic board and effectively prevents indoor heat loss.

Description

Technical Field

[0001] This invention relates to the field of wood-plastic flooring technology, specifically to a heat-insulating composite wood-plastic flooring and its manufacturing process. Background Technology

[0002] Solid wood flooring is not very durable in terms of moisture and sunlight. Moisture causes the flooring to swell, and after it dries, it will shrink, causing the gaps between the floorboards to widen. Stone flooring is not only heavy and less wear-resistant, but also brittle, and its flexibility is reduced, affecting its service life and gloss.

[0003] Chinese patent CN216380428U discloses a combined floor insulation structure with high strength. By setting insulation boards in the frame structure, the insulation problem can be solved while ensuring the load-bearing strength of the floor.

[0004] In the aforementioned patent, the insulation board is located inside the floor and does not have an independent support structure. During use, the floor is subjected to external pressure, which over time can cause the internal insulation layer to crack or fall off. Summary of the Invention

[0005] The purpose of this invention is to provide a heat-insulating modular wood-plastic composite flooring and its manufacturing process. The support plate is installed by aligning it with the pressing groove on the bottom of the exterior wood-plastic composite board. The entire heat-insulating pad is used to separate the exterior wood-plastic composite board from the installation surface, preventing moisture from the ground from seeping into the interior of the exterior wood-plastic composite board. At the same time, it can also effectively prevent the loss of indoor temperature, thus solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat-insulating composite wood-plastic flooring, comprising an exterior composite wood-plastic board and a heat-insulating pad, wherein the heat-insulating pad is installed below the exterior composite wood-plastic board and above the laminated frame, the laminated frame comprising a top axis strip and a bottom axis strip, the top axis strip being located above the bottom axis strip, the top axis strip and the bottom axis strip intersecting horizontally and vertically, and the top axis strip and the bottom axis strip being configured as an integral structure.

[0007] Preferably, the top shaft strip has a through-lock groove inside, which extends through to both sides of the top shaft strip. A metal retaining spring is provided inside the through-lock groove. The bottom shaft strip has a positioning hole groove on its outer surface, and a drilled anchor cone is provided inside the positioning hole groove.

[0008] Preferably, one side of the exterior composite wood-plastic board is provided with a splicing mortise, the other side of the exterior composite wood-plastic board is provided with an interlocking tenon block, the bottom of the exterior composite wood-plastic board is provided with a pressing groove, and a rotating support plate is provided below the pressing groove.

[0010] Preferably, the metal snap ring includes corner buckles and spring pieces. The corner buckles are located at both ends of the spring pieces, and the corner buckles and spring pieces are integrated into one structure. The bottom of the spring piece is provided with a bending spring groove, and the metal snap ring is connected to the through-hole lock groove through the spring piece.

[0011] Preferably, the top of the drilling anchor cone is provided with a hexagonal nut, the bottom of the drilling anchor cone is provided with a screw head, the top of the hexagonal nut is provided with an internal nail hole, the internal nail hole extends to the surface of the screw head, and a central through nail is provided inside the internal nail hole.

[0012] Preferably, the bottom of the central through pin is provided with a cross groove, and four spring blocks are provided inside the cross groove, with the bottom of the spring blocks rotatably connected to the cross groove.

[0013] A manufacturing process for a thermally insulated modular wood-plastic composite floor includes the following steps:

[0014] Step 1: Select a log of suitable length as raw material, cut the thickness of the board to 15mm and the width to 90mm, and then groove one side of the board surface with a groove depth of 5mm and a width of 30mm. On the basis of the first groove, make a second groove with a groove depth of 5mm and a width of 60mm. The two groovings can form a pressing groove and rotating support plates on both sides of the bottom.

[0015] Step 2: Carve the texture on the other side of the board. Finally, cut splicing grooves and interlocking tenons on both sides of each board for splicing between finished wood-plastic flooring. Then, refer to the grooves on the bottom of the board to make a mold.

[0016] Step 3: The heat insulation pad produced by the molding process can be attached to the pressing groove and rotating support plate at the bottom of the exterior composite wood-plastic board. During installation, first assemble the heat insulation pad with the exterior composite wood-plastic board, and finally install the assembled exterior composite wood-plastic board with the laminated frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the support plate pad is installed by aligning it with the pressing groove at the bottom of the exterior composite wood-plastic board. The entire heat insulation pad is used to separate the exterior composite wood-plastic board from the installation surface, preventing moisture from the ground from seeping into the interior of the exterior composite wood-plastic board, and also effectively preventing the loss of indoor temperature.

[0019] 2. In this invention, metal snap rings are distributed on both sides of the top shaft strip. After the support plate pad and the outer composite wood-plastic board are assembled, the pad groove at the bottom of the support plate pad is pressed into the top shaft strip. When the support plate pad is pressed in, it squeezes the metal snap ring, causing the corner buckles at both ends of the metal snap ring to bend downward. Then, under the reaction force of the spring piece and the bending spring groove, it pops out, thereby clamping the support plate pad and completing the fixing operation, thus preventing the template from separating and falling off.

[0027] 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.

[0028] To address the issue that the insulation board is located inside the floor and lacks its own independent support structure, while the floor is subjected to external pressure during use, which can lead to the internal insulation layer cracking or detaching over time; please refer to... Figure 1-6 This embodiment provides the following technical solution:

[0029] A type of heat-insulating modular wood-plastic composite flooring includes an exterior composite wood-plastic board 1 and a heat-insulating pad 3. The heat-insulating pad 3 is installed below the exterior composite wood-plastic board 1 and above a laminated frame 2. The laminated frame 2 includes a top axis strip 201 and a bottom axis strip 202. The top axis strip 201 is located above the bottom axis strip 202, and the top axis strip 201 and the bottom axis strip 202 intersect horizontally and vertically. The top axis strip 201 and the bottom axis strip 202 are configured as an integral structure. The top axis strip 201 has a through-lock groove 2011 inside. The through-hole extends to both sides of the top shaft strip 201. The inside of the through-hole lock groove 2011 is provided with a metal snap ring 203. The outer surface of the bottom shaft strip 202 is provided with a positioning hole groove 2021. The inside of the positioning hole groove 2021 is provided with a drilled anchor cone 204. One side of the outer composite wood-plastic board 1 is provided with a splicing mortise 101. The other side of the outer composite wood-plastic board 1 is provided with a tenon block 102. The bottom of the outer composite wood-plastic board 1 is provided with a pressing groove 103. The bottom of the pressing groove 103 is provided with a rotating support plate 104. The rotating support plate 104 and the outer composite wood-plastic board 1 are integrated into one structure.

[0030] In this embodiment, the heat insulation pad 3 can be attached to the pressing groove 103 and the rotating support plate 104 at the bottom of the exterior composite wood-plastic board 1. During installation, the heat insulation pad 3 is first assembled with the exterior composite wood-plastic board 1, and then the assembled exterior composite wood-plastic board 1 is installed with the laminated frame 2.

[0031] The heat insulation pad 3 includes a support plate pad 301 and a shock-absorbing pad foot 302. The support plate pad 301 and the shock-absorbing pad foot 302 are set as an integral structure. The shock-absorbing pad foot 302 is located on both sides below the support plate pad 301. A pad groove 303 is provided between the shock-absorbing pad feet 302. The heat insulation pad 3 is connected to the top shaft strip plate 201 through the pad groove 303. The support plate pad 301 is slidably connected to the exterior composite wood-plastic board 1 through the press-fit groove 103. The shock-absorbing pad foot 302 is respectively attached to the rotating support plate 104 and the bottom shaft strip plate 202.

[0032] In this embodiment, the support plate pad 301 is installed by aligning it with the pressing groove 103 at the bottom of the exterior composite wood-plastic board 1. The entire heat insulation pad 3 is used to separate the exterior composite wood-plastic board 1 from the installation surface, so as to prevent moisture from the ground from seeping into the interior of the exterior composite wood-plastic board 1, and at the same time, it can also effectively prevent the loss of indoor temperature.

[0033] The support plate pad 301 is attached to the inside of the pressing groove 103, while the shock-absorbing pad foot 302 is attached to the outside of the rotating support plate 104. When the surface of the exterior composite wood-plastic board 1 is squeezed and bent, the support plate pad 301 at the bottom can play a buffering role and reduce the deformation force of the board surface caused by pressure. The shock-absorbing pad foot 302 can prevent impact and friction between the exterior composite wood-plastic board 1 and the bottom frame structure.

[0034] The metal snap ring 203 includes a corner buckle 2031 and a spring piece 2032. The corner buckle 2031 is located at both ends of the spring piece 2032. The corner buckle 2031 and the spring piece 2032 are integrated into one piece. The bottom of the spring piece 2032 is provided with a bent spring groove 2033. The metal snap ring 203 is connected to the through lock groove 2011 through the spring piece 2032. The top of the drilled anchor cone 204 is provided with a hexagonal nut 2041. The bottom of the drilled anchor cone 204 is provided with a screw head 2043. The top of the hexagonal nut 2041 is provided with an internal nail hole 2042. The internal nail hole 2042 extends to the surface of the screw head 2043. The inside of the internal nail hole 2042 is provided with a central through nail 2044. The bottom of the central through nail 2044 is provided with a cross groove 2045. The inside of the cross groove 2045 is provided with four spring blocks 2046. The bottom of the spring blocks 2046 is rotatably connected to the cross groove 2045.

[0035] In this embodiment, metal snap rings 203 are distributed on both sides of the top shaft strip 201. After the support plate pad 301 and the outer composite wood-plastic board 1 are assembled, the pad groove 303 at the bottom of the support plate pad 301 is pressed into the top shaft strip 201. When the support plate pad 301 is pressed in, it squeezes the metal snap ring 203, causing the corner buckles 2031 at both ends of the metal snap ring 203 to bend downward. Then, under the reaction force of the spring piece 2032 and the bending spring groove 2033, it pops out, thereby clamping the support plate pad 301 to complete the fixing operation and prevent the template from separating and falling off.

[0036] The bottom shaft strip 202 is fixed to the ground by drilling anchor cones 204. First, drill holes in the ground according to the distribution of built-in nail holes 2042. Then, screw the screw head 2043 into the ground. Then, insert the center through nail 2044 through the built-in nail hole 2042 on the surface of the hexagonal nut 2041 and nail the center through nail 2044 into the drilled hole in the ground. After the center through nail 2044 is inserted, the spring block 2046 at the front end will pop out from the cross groove 2045. In this way, the frame fixing operation can be completed.

[0037] The working principle involves selecting logs of suitable length as raw materials, cutting the thickness of the boards to 15mm and the width to 90mm, and then grooving one side of the board surface with a groove depth of 5mm and a width of 30mm. A second groove is then made on the basis of the first groove, with a groove depth of 5mm and a width of 60mm. The two groovings form a pressing groove 103 and rotating support plates 104 on both sides of the bottom. The other side of the board surface is then carved with patterns. Finally, splicing mortises 101 and interlocking tenons 102 are cut on both sides of each board for splicing operations between finished wood-plastic composite flooring. Then, a mold is made based on the grooves on the bottom of the board. The heat insulation pad 3 produced by the mold can be attached to the pressing groove 103 and rotating support plate 104 on the bottom of the exterior composite wood-plastic board 1. During installation, the heat insulation pad 3 is first assembled with the exterior composite wood-plastic board 1, and finally the spliced ​​exterior composite wood-plastic board 1 is installed with the laminated frame 2.
