Description

Technical Field

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

[0002] Traditional wood-plastic wall panels use an integrated extrusion molding process, with a hollow channel in the middle, mainly to improve strength and also provide some sound insulation, but the effect is not ideal. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a wood-plastic composite wall panel that features good sound insulation.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A wood-plastic composite wall panel, comprising:

[0006] The first plate has a first arched portion, the first arched portion has several pressing portions, and one end of the first plate has a tenon structure.

[0007] The second plate has a second arched portion corresponding to the first arched portion. The first arched portion and the second arched portion form a cavity. The pressing portion is located in the cavity. The other end of the first plate is combined with the second plate to form a female tenon structure. The female tenon structure corresponds to the male tenon structure.

[0008] The sound-absorbing cotton is disposed at the bottom of the second arched part and is squeezed and fixed by the extrusion part.

[0009] In the aforementioned wood-plastic composite wall panel, the first panel and the second panel are connected by screws, with the first panel exposed on the outer side.

[0010] In the aforementioned wood-plastic composite wall panel, the screw passes through the second panel and the sound insulation cotton and is fixedly connected to the extrusion part.

[0011] In the aforementioned wood-plastic composite wall panel, the extrusion sections are equidistantly spaced at the bottom of the first arched section.

[0012] In the aforementioned wood-plastic composite wall panel, the first panel has a first connecting groove at both ends, and the second panel has a second protrusion at both ends; the two second protrusions can be inserted into the two first connecting grooves.

[0013] Compared with the prior art, this application has the following advantages:

[0014] In this application, the first arched portion of the first panel and the second arched portion of the second panel form a corresponding structure, which can effectively improve the overall structural stability of the wall panel. Several extrusion portions inside the first arched portion are located in the cavity, which enhances the support strength inside the first and second panels. They also form a distributed stress structure through cooperation with the second arched portion, reducing the risk of deformation under external impact. Moreover, the separate design of the first and second panels is to facilitate the installation of sound insulation cotton, allowing the sound insulation cotton to fully cover the cavity. The specially designed sound insulation cotton is located at the bottom of the second arched portion and is squeezed and fixed by the extrusion portions, ensuring that the sound insulation cotton can be stably filled in the cavity. The sound insulation cotton significantly increases the sound insulation 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 2As shown, a wood-plastic composite wall panel includes: a first panel 2, a second panel 3, and sound insulation cotton 4. The first panel 2 has a first arched portion 21, and the first arched portion 21 has a plurality of extrusion portions 22. One end of the first panel 2 has a male tenon structure 23. The second panel 3 has a second arched portion 31 corresponding to the first arched portion 21. The first arched portion 21 and the second arched portion 31 form a cavity 5. The extrusion portions 22 are located in the cavity 5. The other end of the first panel 2 and the second panel 3 are combined to form a female tenon structure 32, and the female tenon structure 32 corresponds to the male tenon structure 23. The sound insulation cotton 4 is disposed at the bottom of the second arched portion 31 and is fixed by extrusion portions 22.

[0025] In this application, the first arched portion 21 of the first plate 2 and the second arched portion 31 of the second plate 3 form a corresponding structure, which can effectively improve the overall structural stability of the wall panel. Several extrusion portions 22 inside the first arched portion 21 are located in the cavity 5, which enhances the internal support of the first plate 2 and the second plate 3. They also form a distributed stress structure through cooperation with the second arched portion 31, reducing the risk of deformation under external impact. Moreover, the separate design of the first plate 2 and the second plate 3 is to facilitate the installation of the sound insulation cotton 4, allowing the sound insulation cotton 4 to fully cover the cavity. The specially designed sound insulation cotton 4 is located at the bottom of the second arched portion 31 and is squeezed and fixed by the extrusion portions 22, ensuring that the sound insulation cotton 4 can be stably filled in the cavity 5. The sound insulation cotton 4 significantly increases the sound insulation effect.

[0026] Specifically, the first plate 2 and the second plate 3 are connected by screws 6, with the first plate 2 exposed on the outer side.

[0027] The screw 6 connection serves as a rigid fixing method, tightly binding the first plate 2 and the second plate 3 into a whole, avoiding the loosening problems that may occur with structural fitting alone. The screw 6 is not visible on this side.

[0028] Specifically, screw 6 passes through the second plate 3 and the sound insulation cotton 3 and is fixedly connected to the extrusion part 22.

[0029] After the screws 6 are connected, more screws 6 can be inserted into the pressing part 22, thus improving the connection strength.

[0030] Specifically, the extrusion section 22 is equidistantly arranged at the bottom of the first arched section 21.

[0031] Specifically, the first plate 2 has first connecting grooves 24 at both ends, and the second plate 3 has second protrusions 33 at both ends; the two second protrusions 33 can be inserted into the two first connecting grooves 24.

[0032] The corresponding insertion design of the connecting groove and the protrusion forms a concave-convex interlocking structure, which can accurately position the relative positions of the first plate 2 and the second plate 3, avoiding offset or misalignment during assembly. At the same time, it can reduce the possibility of external air and moisture seeping into the interior through gaps, thus improving the overall sealing performance.

[0033] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.
