Description

Technical Field

[0001] This utility model relates to the field of composite panel technology, and in particular to a honeycomb core composite panel. Background Technology

[0002] As people's living standards continue to improve, their requirements for the living environment are also increasing. Especially in the home furnishing sector, consumers are paying more and more attention to the environmental friendliness, warmth, and comfort of decorative materials.

[0003] Currently, the mainstream high-end flooring products on the market are solid wood flooring and engineered wood flooring, but they still have some obvious drawbacks: they are relatively expensive, susceptible to water and moisture damage, prone to warping, not fireproof, and susceptible to insect infestation; some products also contain excessive levels of formaldehyde. Similarly, solid wood wall panels also have similar problems, limiting their widespread application in modern homes. Utility Model Content

[0004] In view of this, the present invention aims to provide a honeycomb core composite board, which uses a honeycomb core board in the middle and is surrounded by a stone-plastic board, thus solving the problems of low water absorption and deformation, fire resistance and insect resistance.

[0005] To achieve the above objectives, the technical solution created by this utility model is implemented as follows:

[0006] A honeycomb core composite panel includes: a honeycomb core panel; a stone-plastic composite panel, the stone-plastic composite panel including a top panel, a bottom panel and four side panels; the top panel, the bottom panel and the four side panels together constitute a closed enclosure structure with an internal accommodating space; wherein, at least two opposite side panels are respectively provided with matching male and female tenons on their outer surfaces; the honeycomb core panel is disposed within the accommodating space; and a decorative layer, the decorative layer covering the top surface of the stone-plastic composite panel.

[0007] Furthermore, it also includes a balancing layer, which covers the lower surface of the stone-plastic panel.

[0008] Furthermore, both the decorative layer and the balancing layer are made of wood veneer.

[0009] Furthermore, both the decorative layer and the balancing layer are made of melamine board.

[0010] Furthermore, the decorative layer is a resin film or a PVC film.

[0011] Furthermore, the male tenon is a boss, and the female tenon is a groove that fits the boss.

[0012] Furthermore, the male tenon has a protrusion at its mating end, and the bottom surface of the protrusion forms an interlocking space with the bottom surface of the stone-plastic board; the female tenon has a recess at its mating end that matches the protrusion, and the end face of the recess has an interlocking block that matches the interlocking space.

[0013] Furthermore, the male tenon has a tenon head at its mating end, the tenon head including a first groove and a first wedge, the first groove being located on the upper part of the first wedge; the bottom surface of the tenon has a groove; the groove and the bottom surface of the tenon form a locking space for locking the female tenon; the mating end of the female tenon has a second wedge that matches the first groove, and a second groove that matches the first wedge; a third wedge that matches the groove is also provided on the end face of the second groove.

[0014] Furthermore, the honeycomb core panel is made of aluminum alloy or resin.

[0015] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0016] 1) The honeycomb core panel is made of aluminum alloy. Aluminum alloy not only reduces the weight of the composite panel, but also reduces costs during transportation and installation. At the same time, the honeycomb structure contains a large amount of air, which provides sound insulation and heat insulation properties, and it is not easily deformed, thus having functions such as shock absorption, sound insulation, heat preservation, and flame retardancy.

[0017] 2) Stone-plastic composite panels can guarantee the impact strength and compressive strength of composite panels while greatly reducing the cost. At the same time, stone-plastic composite panels also provide fire resistance and insect protection.

[0018] 3) The engagement of the slot and the third wedge allows for precise horizontal positioning, preventing relative horizontal movement between the composite panels. The engagement of the first groove and the second wedge, as well as the engagement between them, allows for precise vertical positioning, preventing relative vertical movement between the composite panels. The mortise and tenon structure ensures a secure connection between the composite panels, preventing problems such as arching and detachment caused by expansion and contraction of the composite panels.

[0019] 4) The thickness of the wood veneer is 0.2mm~2mm. Within this thickness range, the wood veneer exhibits minimal water absorption and deformation. Decorative wood veneer is used on the top surface of the stone-plastic composite board. Due to the honeycomb structure and the good stability and low deformation rate of the stone-plastic composite board, the thin wood veneer used on the top surface is guaranteed not to crack or delaminate. This not only preserves the decorative effect of the wood itself but also significantly reduces the product cost. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 3 As shown in the figure, a honeycomb core composite panel provided by this utility model includes: a honeycomb core panel 1, a stone-plastic panel 2, and a decorative layer 3.

[0031] The stone-plastic composite panel 2 includes a top panel, a bottom panel, and four side panels, which together form a closed enclosure structure with internal accommodating space. At least two opposing side panels are provided with mating male tenons 22 and female tenons 21. The honeycomb core panel 1 is glued into the accommodating space. The decorative layer 3 is glued to the upper surface of the stone-plastic composite panel 2. In this embodiment, both pairs of opposing side panels have male tenons 22 and female tenons 21 on their outer surfaces. That is, in each pair of opposing side panels, one side panel has a male tenon 22, and the other side panel has a female tenon 21.

[0032] When the decorative layer 3 is made of wood veneer or melamine board, a balancing layer 4 needs to be added to the honeycomb core composite panel. The balancing layer 4 is adhered to the lower surface of the stone-plastic board 2, and the material of the balancing layer 4 corresponds to the material of the decorative layer 3. However, when the decorative layer 3 is made of PVC film or resin film, a balancing layer is not required.

[0033] In this embodiment, decorative layer 3 and balancing layer 4 are wood veneer layers with a thickness of 0.2mm to 2mm. Within this thickness range, the wood veneer exhibits minimal water absorption and deformation. The upper surface of the stone-plastic composite panel 2 uses decorative wood veneer. Due to the honeycomb structure and the good stability and low deformation rate of the stone-plastic composite panel, the thin wood veneer used on the upper surface is guaranteed not to crack or delaminate. This not only preserves the decorative effect of the wood itself but also significantly reduces the product cost. The bottom surface of the stone-plastic composite panel 2 also uses wood veneer, primarily to balance the stress of the upper surface wood veneer and prevent the product from bending and deforming due to uneven stress.

[0034] The honeycomb core panel 1 and the stone-plastic panel 2 can be assembled using the following two methods:

[0035] One method is the separate bonding method: Apply adhesive to the top and bottom panels separately. Place the honeycomb core panel and four side panels on the bottom stone-plastic panel. Cover with the top stone-plastic panel and press them together.

[0036] The second method is the assembly method: First, assemble the base plate and four side plates into a box with an opening, and apply adhesive to the inner surface of the box. Then, place the honeycomb core panel 1 into the box. Finally, apply adhesive to the inner surface of the top plate and attach it to the top surface of the honeycomb core panel 1 to complete the sealing.

[0037] In this embodiment, the honeycomb core panel 1 is made of aluminum alloy. Aluminum alloy not only reduces the weight of the composite panel but also lowers costs during transportation and installation. Simultaneously, the honeycomb structure contains a large amount of air, providing sound insulation and heat insulation properties, and is not easily deformed, thus offering shock absorption, sound insulation, heat preservation, and flame retardancy. In another embodiment, the honeycomb core panel 1 is made of resin.

[0038] Stone-plastic composite board 2 (SPC) is made by extruding stone powder and polyvinyl chloride resin, with both the top and bottom panels having a thickness of 1.5mm to 2mm. SPC ensures the impact and compressive strength of composite panels while significantly reducing costs. Simultaneously, it provides fire resistance and insect protection.

[0039] Example 1

[0040] In this embodiment, the structure of the male tenon 22 and the female tenon 21 is as follows:

[0041] The male tenon 22 has a tenon at its mating end. The tenon includes a first groove 221 and a first wedge 222. The first groove 221 is located on the upper part of the first wedge 222. The bottom surface of the tenon has a slot 223. The slot 223 and the bottom surface of the tenon form a locking space for locking the female tenon 21.

[0042] The mating end of the tenon 21 is provided with a second wedge 211 that matches the first groove 221, and a second groove 212 that matches the first wedge 222. A third wedge 213 that matches the slot 223 is also provided on the end face of the second groove 212.

[0043] The engagement of the slot 223 and the third wedge 213 allows for precise horizontal positioning, preventing relative horizontal movement between the composite panels. The engagement of the first groove 221 and the second wedge 211, as well as the engagement of the first wedge 222 and the second groove 212, allows for precise vertical positioning, preventing relative vertical movement between the composite panels. The mortise and tenon structure of the male tenon 222 and the female tenon 21 ensures a secure connection between the composite panels, preventing problems such as arching and detachment caused by the expansion and contraction of the composite panels.

[0044] Example 2

[0045] In another embodiment, the male tenon 22 and the female tenon 21 are structured as follows:

[0046] The male tenon 22 has a protrusion 22a at its mating end, and the bottom surface of the protrusion 22a forms an interlocking space 22b with the bottom surface of the stone-plastic board 2. The female tenon 21 has a recess 21a at its mating end that matches the protrusion 22a, and the end face of the recess 21a has an interlocking block 21b that matches the interlocking space 22b.

[0047] The fitting design of the protrusion 22a and the recess 21a, as well as the interlocking block 21b and the interlocking space 22b, enables a tight connection, thereby enhancing the stability between the composite panels and effectively preventing loosening or displacement. This splicing structure can disperse external forces, significantly improving the overall impact resistance of the composite panel and making it more durable during use. Simultaneously, it reduces moisture penetration, effectively improving the waterproof and moisture-proof performance of the composite panel, extending its service life, and reducing the risk of deformation or damage caused by moisture.

[0048] Example 3

[0049] In yet another embodiment, the structure of the male tenon 22 and the female tenon 21 can also be:

[0050] The male tenon 22 is a boss, and the female tenon 21 is a groove that fits the boss. The design of the boss and groove makes splicing between composite panels simpler and faster. Simply insert the boss into the groove for quick installation. This reduces installation time and labor costs, making it particularly suitable for large-area installations or rapid renovation projects.

[0051] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
