Description

Technical Field

[0001] This application relates to the field of partition wall design technology, and in particular to partition wall devices. Background Technology

[0002] With the expansion of different consumption scenarios, modular walls are used in scene setting and decoration to create different scenes. By simply piecing together the modular walls, different scene settings can be switched.

[0003] In related technologies, splicing walls generally use honeycomb panels made of aluminum alloy as the main core of the wall to improve the structural strength of the splicing wall.

[0004] However, this type of splicing wall has the following drawbacks: On the one hand, while the use of metal materials such as aluminum alloys can ensure sufficient structural strength, their excessively fast thermal conductivity results in poor insulation performance. On the other hand, the gaps between the splicing walls are still too large, making installation prone to instability and leading to poor connection strength between adjacent splicing walls. Utility Model Content

[0005] Therefore, it is necessary to provide a partition wall device that addresses the issue of how to balance the structural strength and thermal insulation performance of the spliced ​​wall during use, while also ensuring the aesthetics of the partition wall device.

[0006] A partition wall device, the partition wall device comprising:

[0007] At least two wall bodies; at least two of the wall bodies are arranged adjacent to each other;

[0009] The first inner insulation layer protrudes from the outer insulation layer to form a convex portion, and the second inner insulation layer is recessed from the outer insulation layer to form a concave portion; the convex portion and the concave portion are mutually inserted and matched; and the material hardness of the decorative panel body is greater than the material hardness of the outer insulation layer, the first inner insulation layer and the second inner insulation layer.

[0010] In one embodiment, the thickness of the inner insulation layer is less than the thickness of the outer insulation layer.

[0011] In one embodiment, the outer insulation layer has a first side and a second side opposite to each other along its length; the inner insulation layer has a third side and a fourth side along its length; wherein...

[0012] The third side of the first inner insulation layer protrudes relative to the first side to form the protrusion; the fourth side of the first inner insulation layer is recessed relative to the second side to form the recess.

[0013] And / or, the third side of the second inner insulation layer is recessed relative to the first side to form the recess; the fourth side of the second inner insulation layer is protruding relative to the second side to form the protrusion.

[0014] In one embodiment, the decorative panel assembly further includes a toughening layer; wherein,

[0015] The toughening layer is disposed between the outer insulation layer and the decorative panel assembly;

[0016] And / or, the toughening layer is disposed between the outer insulation layer and the inner insulation layer.

[0017] In one embodiment, the toughening layer is bonded to the outer insulation layer.

[0018] In one embodiment, the toughening layer comprises a non-metallic inorganic fiber layer and an adhesive portion; the non-metallic inorganic fiber layer comprises a mesh structure; the adhesive portion is disposed on the mesh structure such that at least a portion of the adhesive portion is coplanar with the non-metallic inorganic fiber layer.

[0023] In one embodiment, the partition wall device includes multiple sets of the decorative panel assemblies; wherein two sets of the decorative panel assemblies are respectively disposed on two opposite sides of the wall body along the thickness direction.

[0024] The aforementioned partition wall device, through the addition of external and internal insulation layers, facilitates an increase in the thickness of the insulation layer, thereby improving the insulation effect of the partition wall device. Simultaneously, the decorative panel body enhances the structural strength of the partition wall device.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] See Figure 1 As shown, this application provides a partition wall device 10, including a decorative panel assembly 100 and a plurality of wall bodies 200. At least two wall bodies 200 are arranged adjacent to each other.

[0034] The decorative panel assembly 100 includes an outer insulation layer 110, an inner insulation layer 120, and a decorative panel body 130. The wall body 200, inner insulation layer 120, outer insulation layer 110, and decorative panel body 130 are sequentially stacked along the thickness direction X of the wall body 200. The two inner insulation layers 120 corresponding to two adjacent wall bodies 200 are respectively a first inner insulation layer 121 and a second inner insulation layer 122.

[0035] like Figure 2 As shown, the first inner insulation layer 121 protrudes from the outer insulation layer 110 to form a protrusion 120b, and the second inner insulation layer 122 is recessed from the outer insulation layer 110 to form a recess 120a. The protrusion 120b and the recess 120a are positioned and mated together. Furthermore, the material hardness of the decorative panel body 130 is greater than that of the outer insulation layer 110, the first inner insulation layer 121, and the second inner insulation layer 122.

[0036] It is understandable that the arrangement of the outer insulation layer 110 and the inner insulation layer 120 helps to increase the thickness of the insulation layer, thereby improving the insulation effect of the partition wall device 10. Simultaneously, the arrangement of the decorative panel body 130 helps to improve the structural strength of the partition wall device 10. Furthermore, the first inner insulation layer 121 and the second inner insulation layer 122 in the two adjacent wall bodies 200, respectively, are formed with protrusions 120b and recesses 120a. When two adjacent partition wall devices 10 are joined, the protrusions 120b and recesses 120a engage with each other, causing a portion of the protrusion 120b to overlap with the corresponding outer insulation layer 110 of the recess 120a. This increases the contact area between the two adjacent decorative panel assemblies 100, thereby improving the connection stability of the two adjacent decorative panel assemblies 100 and ensuring the stable appearance performance of the partition wall decoration.

[0037] Furthermore, unlike the external insulation layer 110 and the internal insulation layer 120 which are both processed to form recesses 120a or convex portions 120b, this embodiment can reduce the risk of damage when processing the external insulation layer 110 to form recesses 120a or convex portions 120b, thus avoiding affecting the insulation performance of the external insulation layer; at the same time, it reduces the processing steps of the external insulation layer 110, which is beneficial to improving the processing efficiency of the partition wall device 10.

[0038] In some embodiments, see back Figure 1 as well as Figure 2 The thickness of the inner insulation layer 120 is less than the thickness of the outer insulation layer 110.

[0039] Thus, the relatively thick outer insulation layer 110 enhances its ability to block external heat or cold, thereby improving the insulation performance of the partition wall device 10. Furthermore, the relatively thin inner insulation layer 120 maintains sufficient insulation performance without excessively increasing the overall weight or thickness of the partition wall device 10, preserving its lightweight and space-efficient design. Additionally, the presence of protrusions 120b or recesses 120a on the thinner inner insulation layer helps reduce damage to the inner insulation layer 120 during processing, ensuring its insulation performance and reducing the difficulty of processing it.

[0040] In one embodiment, see back Figure 1 as well as Figure 2 The partition wall device 10 includes two wall bodies 200, a first decorative panel assembly 100a, and a second decorative panel assembly 100b. The first decorative panel assembly 100a is disposed on the surface of one wall body 200. The second decorative panel assembly 100b is disposed on the surface of the other wall body 200. The corresponding first inner insulation layer 121 in the first decorative panel assembly 100a is recessed relative to the outer insulation layer 110 to form a recess 120a. The corresponding second inner insulation layer 122 in the second decorative panel assembly 100b protrudes relative to the outer insulation layer 110 to form a protrusion 120b. The protrusion 120b and the recess 120a are interlocked and mutually limiting.

[0041] In another embodiment, such as Figure 3 As shown, the partition wall device 10 includes at least three wall bodies 200, and at least one decorative panel assembly 100 needs to be mated with the decorative panel assemblies 100 on both sides. Figure 3 As shown, the outer insulation layer 110 has a first side 111 and a second side 112 opposite to each other along the length direction Y. The inner insulation layer 120 has a third side 120c and a fourth side 120d along the length direction Y.

[0042] Specifically, in one embodiment, such as Figure 3As shown, the third side 120c of the inner insulation layer 120 protrudes relative to the first side 111 to form a protrusion 120b. The fourth side 120d of the inner insulation layer 120 is recessed relative to the second side 112 to form a recess 120a. That is, at this time, a decorative panel assembly 100 can be used to mate with the decorative panel assemblies 100 on both sides, and the third side 120c is used to form the protrusion 120b, and the fourth side 120d is used to form the recess 120a. This allows the decorative panel assemblies 100 that need to mate with the decorative panel assemblies 100 on both sides to be mass-produced without the need for each decorative panel assembly 100 to have different positions for the recess 120a and the protrusion 120b, reducing the processing difficulty and improving processing efficiency.

[0043] In some embodiments, such as Figure 3 As shown, the decorative panel assembly 100 also includes a toughening layer 140. In one embodiment, the toughening layer 140 is disposed between the outer insulation layer 110 and the decorative panel assembly 100. In another embodiment, the toughening layer 140 is disposed between the outer insulation layer 110 and the inner insulation layer 120.

[0044] Thus, the toughening layer 140 is provided to enhance the toughness of the side edge of the outer insulation layer 110, so that when the outer insulation layer 110 is subjected to external impact, the toughening layer 140 provides the ability to absorb and disperse the impact, which helps to disperse the impact stress between the insulation layer and the decorative panel body 130, thereby improving the impact resistance of the entire decorative panel assembly 100.

[0045] Alternatively, in one embodiment, see back Figure 3 The decorative panel assembly 100 includes a first toughening layer 141 and a second toughening layer 142. The decorative panel body 130, the first toughening layer 141, the outer insulation layer 110, and the second toughening layer 142 are sequentially arranged along the thickness direction X. The first inner insulation layer 121 and the second inner insulation layer 122 are connected to the decorative panel assembly 100 through the second toughening layer 142.

[0046] Thus, the provision of the first toughening layer 141 and the second toughening layer 142 enhances the overall toughness of both sides of the outer insulation layer 110. When subjected to external impact, the toughening layer 140 provides the ability to absorb and disperse impact, which is beneficial to disperse the impact stress between the insulation layer and the decorative panel body 130, and can achieve stress dispersion balance, preventing local stress concentration from causing damage to the outer insulation layer 110, thereby improving the impact resistance of the entire decorative panel assembly 100.

[0047] It should be noted that the connection between the toughening layer 140 and the insulation layer can be, but is not limited to, bonding, integral molding, etc., and no further restrictions are imposed here.

[0048] Furthermore, in one embodiment, the toughening layer 140 is bonded to the outer insulation layer 110.

[0049] Thus, the adhesive bonding method can reduce the gap between the toughening layer 140 and the outer insulation layer 110, thereby improving the sealing and contact performance between the decorative panel assembly 100, reducing heat loss, improving insulation performance, and reducing the impact of external dust particles and moisture, thus extending the service life of the decorative panel assembly 100. Furthermore, the insulation layer (such as EPS) may have tiny, non-closed pores. By bonding the toughening layer 140 to at least one side of the outer insulation layer 110, the non-closed pores of the outer insulation layer 110 can be effectively sealed, effectively preventing the passage of heat and moisture, and enhancing the overall sealing and insulation performance.

[0050] In another embodiment, the decorative panel assembly 100 further comprises a non-metallic inorganic fiber layer and an adhesive portion. The non-metallic inorganic fiber layer has a mesh structure. The adhesive portion is disposed on the mesh structure such that at least a portion of the adhesive portion is coplanar with the non-metallic inorganic fiber layer. Thus, the non-metallic inorganic fiber layer adopts a mesh structure, which has high specific strength and specific modulus, providing sufficient strength and toughness at a relatively thin thickness, thereby helping to reduce the thickness of the decorative panel assembly 100. Furthermore, the coplanar arrangement of the adhesive portion and the non-metallic inorganic fiber layer eliminates the need for additional thickness.

[0051] Optionally, the first adhesive portion and the second adhesive portion may include at least one or a combination of cementitious materials, epoxy resin adhesive materials, acrylic adhesive materials, etc.

[0052] Optionally, in one embodiment, the non-metallic inorganic fiber layer comprises glass fiber material. Thus, the glass fiber material possesses good toughness, providing excellent buffering and stress dispersion for the outer insulation layer 110, effectively improving the structural stability of the decorative panel assembly 100. Furthermore, the glass fiber material also exhibits good corrosion resistance, extending the service life of the decorative panel assembly 100.

[0053] Further, optionally, in one embodiment, both the outer insulation layer 110 and the inner insulation layer 120 comprise XPS (Extruded Polystyrene) sheets. Thus, because XPS sheets have a closed-cell structure, they can effectively prevent air convection, thereby further reducing heat transfer. Simultaneously, XPS sheets also have excellent waterproof and moisture-proof properties, effectively preventing water vapor penetration and keeping the wall body 200 dry and stable. Furthermore, XPS sheets also have high compressive strength and load-bearing capacity, ensuring the structural stability and safety of the decorative panel assembly 100.

[0054] Optionally, in another embodiment, the decorative panel body 130 comprises PVC (Polyvinyl chloride) material. Thus, PVC material has good corrosion resistance, effectively resisting environmental erosion and extending the service life of the decorative panel assembly 100. Furthermore, PVC material also has high hardness and toughness, maintaining the flatness and stability of the decorative panel body 130, and is not easily deformed or cracked. In addition, PVC material has good processing properties, is easy to cut, bend, and bond, facilitating processing and installation during the manufacturing process of the decorative panel assembly 100.

[0055] In some embodiments, combined with Figure 4 as well as Figure 5 As shown, the outer insulation layer 110 has a first side 111 and a second side 112 opposite to each other along the length direction Y of the outer insulation layer 110, and a portion of the decorative panel body 130 covers at least a portion of at least one of the first side 111 and the second side 112. The decorative panel body 130 is spaced apart from the side edge of the inner insulation layer 120.

[0056] Understandably, a portion of the decorative panel body 130 covers at least a portion of at least one of the first side 111 and the second side 112, enabling the decorative panel body 130 to shield at least a portion of the outer insulation layer 110, thus protecting it from external damage. Furthermore, when two adjacent decorative panel assemblies 100 are joined, the two decorative panel bodies 130 can abut against each other, making the inner insulation layer 120 less visible from the perspective of the partition wall device 10, thereby improving the appearance of the partition wall device 10.

[0057] In other embodiments, see back Figure 4 The partition wall device 10 includes multiple sets of decorative panel assemblies 100. Two sets of decorative panel assemblies 100 are respectively disposed on two opposite sides of the wall body 200 along the thickness direction X. Thus, by distributing the two sets of decorative panel assemblies 100 on both sides of the wall body 200, the heat exchange efficiency between the inside and outside of the wall is further reduced, fully optimizing the thermal insulation performance of the partition wall device 10.

[0058] In one embodiment, in conjunction with the first decorative panel assembly 100a and the second decorative panel assembly 100b described in the above embodiments, the partition wall device 10 further includes a third decorative panel assembly 100c and a fourth decorative panel assembly 100d. The first decorative panel assembly 100a and the third decorative panel assembly 100c are arranged opposite to each other, and the second decorative panel assembly 100b and the fourth decorative panel assembly 100d are arranged opposite to each other.

[0059] Specifically, in one embodiment, the corresponding first inner insulation layers 121 in the first decorative panel assembly 100a and the third decorative panel assembly 100c are recessed relative to the outer insulation layer 110 to form recesses 120a, and the corresponding second inner insulation layers 122 in the second decorative panel assembly 100b and the fourth decorative panel assembly 100d protrude relative to the outer insulation layer 110 to form protrusions 120b. That is, the structures of the first inner insulation layers 121 in the third decorative panel assembly 100c and the first decorative panel assembly 100a can be designed to be identical, and the structures of the second inner insulation layers 122 in the fourth decorative panel assembly 100d and the second decorative panel assembly 100b can be set to be identical. This facilitates direct connection by operators and improves installation efficiency.

[0060] In another embodiment, see back Figure 2 The first inner insulation layer 121 of the first decorative panel assembly 100a is recessed relative to the outer insulation layer 110 to form a recess 120a; the second inner insulation layer 122 of the second decorative panel assembly 100b protrudes relative to the outer insulation layer 110 to form a protrusion 120b. The first inner insulation layer 121 of the third decorative panel assembly 100c protrudes relative to the outer insulation layer 110, and the second inner insulation layer 122 of the fourth decorative panel assembly 100d protrudes relative to the outer insulation layer 110 to form a protrusion 120b.

[0061] Thus, by setting the first decorative panel assembly 100a and the second decorative assembly, the load-bearing area of ​​the second inner insulation layer 122 and the outer insulation layer 110 is increased; and by setting the third decorative panel assembly 100c and the fourth decorative panel assembly 100d, the load-bearing area of ​​the inner insulation layer 120 and the outer insulation layer 110 is increased, thereby forming a load-bearing overlapping structure that is staggered along the thickness direction X, thereby improving the structural strength of the partition wall device 10.
