Description

Technical Field

[0001] This utility model relates to the field of wood-plastic wall panel technology, and in particular to a prefabricated wood-plastic wall panel. Background Technology

[0002] To reduce wet work on-site during renovation, prefabricated wall panels are widely used, offering greater environmental friendliness and more efficient construction. Existing prefabricated wall panels, as shown in patent application number CN202022078359.4, include aluminum honeycomb panels, I-beams, and self-tapping screws. The side panels of the aluminum honeycomb panels have snap-fit ​​grooves. During installation, the I-beams are first fixed to the wall using self-tapping screws, and the snap-fit ​​grooves on the side of the aluminum honeycomb panels are then inserted into the I-beams for fixation. While this type of prefabricated wall panel is convenient to install, the aluminum honeycomb panels are fixed to the wall using I-beams and self-tapping screws. When a particular aluminum honeycomb panel needs to be replaced, it cannot be removed from the wall for individual replacement, making subsequent maintenance inconvenient. Utility Model Content

[0003] To address the shortcomings of existing prefabricated wall panels that are inconvenient to replace individually, this utility model proposes a prefabricated wood-molded wall panel that facilitates individual replacement and subsequent maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A prefabricated wood-plastic wall panel includes multiple connectors and multiple splicing panels, wherein the splicing panels include a wood-plastic wall panel substrate and springs;

[0006] The left side of the wood-plastic wall panel substrate is provided with a female groove. One end of the spring is fixedly connected to the bottom of the female groove, and the other end of the spring faces the opening of the female groove and is located inside the female groove. The right side of the wood-plastic wall panel substrate is provided with a male edge that matches the female groove. A cavity is provided on the side of the wood-plastic wall panel substrate near the male edge. The cavity passes through the connecting groove to the back of the wood-plastic wall panel substrate. The connecting groove extends left and right.

[0007] One end of the connector is used to fix it to the wall. The connector can pass through the connecting groove and slide relative to the connecting groove. A fixing key is fixedly connected to the side of the other end of the connector. When the connector passes through the middle of the connecting groove, the fixing key abuts against the inner wall of the cavity. The left and right ends of the connecting groove are widened to form a clearance opening through which the fixing key can pass.

[0008] With the above settings, firstly, dry installation is more environmentally friendly and more efficient; secondly, it facilitates the disassembly and assembly of individual splicing panels, thus making subsequent maintenance easier.

[0009] Furthermore, the length of the spring is L, the distance from the outer end of the spring to the opening of the groove is D, L / D > 2.5, 2mm. <D<4mm。

[0010] With the above settings, the depth of the male side inserted into the female groove is appropriate, making it convenient to disassemble and assemble the splicing plate.

[0011] Furthermore, the outer side of the wood-plastic wall panel substrate is wavy.

[0012] Furthermore, the splicing panel also includes a colored film covering the outside of the wood-plastic wall panel substrate.

[0013] The above settings enhance the aesthetics of the outer side of the splicing panel.

[0014] Furthermore, the connectors are made of self-tapping screws.

[0015] Furthermore, a limiting protrusion is fixedly connected in the middle of the connector, and the distance between the limiting protrusion and the fixing key matches the distance between the cavity and the back of the wood-plastic wall panel substrate.

[0016] The above settings facilitate determining the depth to which the connector is driven into the wall.

[0017] Furthermore, the substrate material of the wood-plastic wall panel is wood-plastic foam material, and a wood-plastic co-extruded layer is provided along the inner wall of the mother groove. Attached Figure Description

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] like Figures 1 to 8As shown, a prefabricated wood-plastic molding wall panel includes multiple connectors 3 and multiple splicing panels, the splicing panels including wood-plastic wall panel substrate 4 and springs 5;

[0028] A female groove 6 is provided on the left side of the wood-plastic wall panel substrate 4. One end of the spring 5 is fixedly connected to the bottom of the female groove 6, and the other end of the spring 5 faces the opening of the female groove 6 and is located inside the female groove 6. A male edge 7 that is adapted to the female groove 6 is provided on the right side of the wood-plastic wall panel substrate 4. A cavity 8 is provided on the side of the wood-plastic wall panel substrate 4 near the male edge 7. The cavity 8 passes through the connecting groove 9 to the back of the wood-plastic wall panel substrate 4. The connecting groove 9 extends to the left and right.

[0029] One end of the connector 3 is used to fix it to the wall. The connector 3 can pass through the connecting groove 9 and slide relative to the connecting groove 9. The other end of the connector 3 is fixedly connected to the side of the fixing key 12. When the connector 3 passes through the middle of the connecting groove 9, the fixing key 12 abuts against the inner wall of the cavity 8. The left and right ends of the connecting groove 9 are widened to form a clearance opening 15 through which the fixing key 12 can pass.

[0030] With the above settings, firstly, dry installation is more environmentally friendly and more efficient; secondly, it facilitates the disassembly and assembly of individual splicing panels, thus making subsequent maintenance easier.

[0031] The width of the splicing panel in this application is customized according to the decoration design requirements; the wood-plastic wall panel substrate 4 of the splicing panel is prefabricated in the factory through an extrusion process; the spring 5 extends left and right; the right end of the spring 5 can be fixed to the bottom of the groove 6 by welding or glue; the left end of the spring 5 faces the groove opening of the groove 6 and is located inside the groove opening; multiple cavities 8 are provided inside the wood-plastic wall panel substrate 4, which helps to reduce the material consumption of the wood-plastic wall panel substrate 4 and reduce the weight of the wood-plastic wall panel substrate 4; the connecting groove 9 extends left and right, with a large width at both ends and a small width in the middle, basically in the shape of a bone; the width of the middle part of the connecting groove 9 is basically the same as the outer diameter of the connector 3;

[0032] Cut the splicing panel, removing the left side and retaining the male edge 7 and connecting groove 9, which will be used as the leftmost splicing panel. Drive one end of the connector 3 into the wall for fixation. Attach the cut splicing panel to the wall. The connector 3 passes through the connecting groove 9 at the left end of the connecting groove 9. Push the splicing panel to the left, so that the left side of the splicing panel abuts against the left side of the wall. The middle of the connecting groove 9 slides to the connector 3. At this point, the fixing key 12 is located inside the cavity 8 and abuts against the side wall of the cavity 8 near the connecting groove 9, preventing the connector 3 from being pulled out and ensuring the splicing panel does not detach from the wall. Figure 2 and Figure 4 ;

[0033] Following the steps above, install the next splicing panel. Fix another connector 3 to the wall, attach the splicing panel to the wall, and let the connector 3 pass through the clearance opening at the left end of the connecting groove 9. Push the splicing panel to the left, and the middle of the connecting groove 9 slides to the connector 3 to prevent the right side of the splicing panel from detaching from the wall. The female groove 6 on the left side of the splicing panel is engaged with the male edge 7 on the right side of the previous splicing panel to prevent the left side of the splicing panel from detaching from the wall. The left end of the spring 5 abuts against the male edge 7 of the previous splicing panel. Continue in this manner to install the remaining splicing panels one by one.

[0034] When installing the rightmost panel, cut off the right side of the panel, retaining the connecting groove 9 and the female groove 6 on the left. Fix the connector 3 to the right side of the wall. Push the previous panel to the left, compressing the spring 5 on the left side of the panel. Hold it by hand to prevent the spring 5 from rebounding. Attach the panel to be installed to the wall. The connector 3 passes through the connecting groove 9 through the clearance opening at the right end of the connecting groove 9. Then push the panel to the right, so that the right side of the panel abuts against the right side of the wall. The middle of the connecting groove 9 slides to the connector 3, preventing the right side of the panel from detaching from the wall. After releasing the hand on the previous panel, the spring 5 on its left rebounds, driving the panel to move to the right. The male edge 7 on the right side of the panel embeds into the female groove 6 on the left side of the rightmost panel, preventing the left side of the rightmost panel from detaching from the wall. The spring 5 on the left side of the rightmost panel abuts against the male edge 7 of the previous panel. Figure 5 At this point, the wall panel installation is complete. Now, as... Figure 6 The left end of spring 5 abuts against the male side 7 of the corresponding splicing plate. Spring 5 is in a free state, that is, spring 5 is not compressed and the elastic force of spring 5 is zero. Spring 5 plays a supporting role and prevents the splicing plate on the wall from moving easily from side to side, thereby preventing the splicing plate from falling off the wall.

[0035] When it is necessary to remove a single splicing panel, move the splicing panel to be removed to the left. Figure 7 ), or move the splicing panel to be disassembled to the right ( Figure 8For example, move the panel to be disassembled 2mm to the left, causing the male edge 7 on the right side of the panel to be disassembled to disengage from the female groove 6 of the adjacent panel on the right. At this time, the clearance at the right end of the connecting groove 9 of the panel to be disassembled moves to the connector 3. Then push the adjacent panel on the left to the left by 4mm, holding it by hand to prevent the panel from springing back. The female groove 6 on the left side of the panel to be disassembled separates from the male edge 7 of the adjacent panel on the left. At this time, both sides of the panel to be disassembled are separated from the adjacent panels, and their connection... Part 3 is located at the clearance opening, allowing the splicing panel to be removed from the wall outwards. After the new wall panel is reattached to the wall, push it to the right so that the male edge 7 on the right side embeds into the female groove 6 of the adjacent splicing panel on the right. The middle of the connecting groove 9 on the right side of the new splicing panel moves to the connector 3, preventing the right side of the splicing panel from detaching from the wall. Then, release the hand on the adjacent splicing panel on the left. The adjacent splicing panel on the left rebounds under the action of spring 5, and the male edge 7 of the adjacent splicing panel on the left inserts into the female groove 6 of the new splicing panel and abuts against spring 5. At this point, the splicing panel replacement is complete. It should be noted that the length of the connecting groove 9 in this application meets the requirements for the movement distance of the splicing panel.

[0036] In one implementation, the length of spring 5 is L, and the distance from the outer end of spring 5 to the opening of the groove 6 is D, where L / D > 2.5, 2mm. <D<4mm。

[0037] With the above settings, the depth to which the male side 7 is inserted into the female groove 6 is appropriate, making it convenient to disassemble and assemble the splicing plate.

[0038] In this application, the distance D from the outer end of the spring 5 to the groove opening of the female groove 6 is specifically 3mm, and L is specifically 9mm. After the splicing plate is installed, the male edge 7 of the splicing plate is inserted into the female groove 6 to a depth of 3mm to ensure a certain degree of secure insertion. Simultaneously, when it is necessary to remove the splicing plate, push the splicing plate to be removed 3mm to the left. Figure 7 The male edge 7 on the right side of the splicing panel to be disassembled is separated from the female groove 6 of the adjacent splicing panel on the right side. The adjacent splicing panel on the left side is pushed 6mm to the left, so that the female groove 6 on the left side of the splicing panel to be disassembled is separated from the male edge 7 of the adjacent splicing panel on the left side. The splicing panel to be disassembled can then be removed from the wall.

[0039] As one implementation method, the outer side of the wood-plastic wall panel substrate 4 is wavy.

[0040] As one implementation method, the splicing panel also includes a color film 10 covering the outside of the wood-plastic wall panel substrate 4.

[0041] The above settings enhance the aesthetics of the outer side of the splicing panel.

[0042] As one implementation method, connector 3 is set as a self-tapping screw.

[0043] As one implementation, a limiting protrusion 11 is fixedly connected in the middle of the connector 3, and the distance between the limiting protrusion 11 and the fixing key 12 matches the distance between the cavity 8 and the back of the wood-plastic wall panel substrate 4.

[0044] The above settings facilitate the positioning of the connector 3's depth into the wall.

[0045] Specifically, after the connector 3 is driven into the wall, the limiting protrusion 11 on the paper connector 3 abuts against the wall, controlling the depth of the connector 3 driven into the wall. When installing the splicing plate, the back of the splicing plate abuts against the limiting protrusion 11, pushing the splicing plate. The middle part of the connecting groove 9 moves to the connector 3. The fixing key 12 and the limiting protrusion 11 are located at the front and rear ends of the connecting groove 9 to prevent the splicing plate from moving back and forth and to improve the installation stability of the splicing plate.

[0046] As one implementation method, the wood-plastic wall panel substrate 4 is made of wood-plastic foam material, and a wood-plastic co-extruded layer 13 is provided along the inner wall of the mother groove 6.

[0047] The wood-plastic composite board substrate and the wood-plastic co-extruded layer 13 of this application are produced by co-extrusion process. The wood-plastic foam material has a low density, which helps to reduce the weight of the spliced ​​board. The wood-plastic co-extruded layer 13 has a higher density, which improves the wear resistance of the mother groove 6.

[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
