[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] like Figure 1 FIG2 is a schematic diagram of a double-faced partition wall according to an embodiment of the present invention, which can be used for interior partitions, such as partition walls between adjacent rooms. The double-faced partition wall of this embodiment includes a plurality of vertical purlin assemblies 10, a plurality of thermal insulation layers 20, a plurality of sound insulation layers 30, and a plurality of decorative panels 40. The thermal insulation layers 20 and the sound insulation layers 30 are respectively flat plates. The plurality of vertical purlin assemblies 10 are vertically spaced apart from each other. The thermal insulation layers 20, the sound insulation layers 30, and the decorative panels 40 are respectively fixed to the vertical purlin assemblies 10. The thermal insulation layers 20 and the sound insulation layers 30 are respectively installed between two adjacent vertical purlin assemblies 10. The sound insulation layer 30 is located between two parallel thermal insulation layers 20. The two decorative panels 40 are respectively fixed to the outsides of the two thermal insulation layers 20.

[0033] like Figure 2 、 Figure 3 As shown, each vertical keel assembly 10 includes two vertical profiles 11, two T-shaped clip profiles 12, and four L-shaped clip profiles 13. Each vertical profile 11 includes a rectangular groove 111 (whose cross-section is rectangular) and two triangular grooves 112 (whose cross-section is a right triangle). The two triangular grooves 112 are located at both ends of the rectangular groove 111, and the opening directions of the rectangular groove 111 and the triangular groove 112 are opposite. That is, the rectangular groove 111 and the two triangular grooves 112 are distributed on the vertical profile 11 along the thickness direction of the double-faced partition wall. In one embodiment of the present invention, each vertical profile 11 can be formed by multiple bending of a metal sheet. In actual applications, the vertical profile 11 can also be processed by existing processes such as extrusion or casting, which will not be described in detail here.

[0034] The two vertical profiles 11 are fixed together with the openings of the rectangular slots 111 facing away from each other. Any triangular slot 112 of each vertical profile 11 combines with the triangular slot 112 of the other vertical profile 11 to form a first trapezoidal slot with its opening facing outward (i.e., facing away from the rectangular slot 111). Specifically, the two vertical profiles 11 can be fixed together using rivets or screws passing through the bottom walls of the two rectangular slots 111. In practical applications, the two vertical profiles 11 can also be fixed together using a snap-fit structure, adhesive, or the like.

[0035] The two insulation layers 20 are respectively fixed to the two sides of the rectangular groove 111 of the two adjacent vertical purlin assemblies 10, and the sound insulation layer 30 is filled in the area enclosed by the rectangular groove 111 of the two adjacent vertical purlin assemblies 10 and the two insulation layers 20. Specifically, the sound insulation layer 30 can be made of materials such as sound-insulating rock wool.

[0036] Each T-shaped clip profile 12 is inserted into a first trapezoidal groove, with at least a portion of the T-shaped clip profile 12 embedded in the opening of the first trapezoidal groove (the main body of the T-shaped clip profile 12 is located in the first trapezoidal groove), and spaced apart from both sides of the opening of the first trapezoidal groove. Each L-shaped clip profile 13 includes a fixed edge and a clip edge, wherein the clip edge is perpendicularly connected to the edge of the fixed edge, resulting in an L-shaped cross-section of the L-shaped clip profile 13. The L-shaped clip profile 13 is fixed (dropped in by self-tapping screws) on the decorative panel 40 in such a way that the fixed edge is attached to the inner surface of the decorative panel 40, and when the decorative panel 40 is installed on the outer side of the insulation layer, the clipping edges of the two L-shaped clip profiles 13 fixed on two adjacent decorative panels 40 are respectively embedded between the T-shaped clip profile 12 and the notch of the first trapezoidal groove (that is, the two clipping edges are respectively located on both sides of the T-shaped clip profile 12), that is, the decorative panel 40 is fixed to the vertical keel assembly 10 by clipping through the T-shaped clip profile 12 and the L-shaped clip profile 13, which greatly facilitates the assembly of the decorative panel 40 and can reduce assembly errors.

[0037] The double-faced partition wall is constructed by providing a rectangular groove 111 and a triangular groove 112 on the two vertical profiles 11 of the vertical keel assembly 10, respectively. The insulation layer 20 is secured between the two adjacent vertical keel assemblies 10 to form a cavity for filling the sound insulation layer. The T-shaped and L-shaped clip profiles 12 and 13 are then snapped into the first trapezoidal groove formed by the two triangular grooves 112, allowing the two decorative panels 40 to be assembled. This facilitates mass and modular production while eliminating the need for subsequent surface painting. Furthermore, the double-faced partition wall features easy installation and disassembly, low installation and maintenance costs, a simple structure, uniform force distribution, good consistency, and an aesthetically pleasing appearance.

[0038] In addition, water pipes, wire pipes, gas pipes, etc. can be placed in the rectangular groove 111 of the above-mentioned vertical keel assembly 10 (a sound insulation layer is filled between the water pipes, wire pipes, gas pipes and the groove wall of the rectangular groove 111), so that the double-faced partition wall can integrate water, heating, electricity, gas, wire and other systems, and realize the integrated assembly of double-faced partition walls with integrated partitions, integrated home furnishings, professional doors, suspended ceilings and floors.

[0039] In one embodiment of the present invention, in order to improve the stability of the decorative panel 40 fixed to the vertical keel assembly 10, the two groove walls of the triangular groove 112 on the vertical profile 11 are elastically connected, and the width of the opening of the first trapezoidal groove formed by the combination of the two triangular grooves 112 is adapted to (for example, the same as or slightly smaller than) the width of the T-shaped clip profile 12 inserted into the opening and the sum of the thicknesses of the clipping edges of the two L-shaped clip profiles 13, so that when the T-shaped clip profile 12 and the two L-shaped clip profiles 13 are inserted into the first trapezoidal groove, the groove walls of the two triangular grooves 112 are slightly deformed, and the elastic restoring force of the groove walls of the triangular grooves 112 clamps the T-shaped clip profile 12 and the L-shaped clip profile 13.

[0040] Furthermore, to prevent the L-shaped clip profile 13 from slipping out of the opening of the first trapezoidal groove, a ridge is formed on the inner surface of the clipping edge of each L-shaped clip profile 13 along the length of the L-shaped clip profile 13. This structure increases the thickness of the clipping edge of the L-shaped clip profile 13 at the location of the ridge, thereby preventing it from slipping out of the opening of the first trapezoidal groove.

[0041] In one embodiment of the present invention, the T-shaped clip profile 12 includes two legs, each with a resilient hook at its free end. When the T-shaped clip profile 12 is inserted into the first trapezoidal groove, the two resilient hooks respectively engage between the bottom wall and the inclined wall of the first trapezoidal groove (i.e., the bottom of the triangular groove), thereby increasing the stability of the T-shaped clip profile 12 within the first trapezoidal groove.

[0042] In addition, each vertical profile 11 includes a second trapezoidal groove 113 with openings located on the two side walls of the rectangular groove 111. The second trapezoidal groove 113 is adjacent to the triangular groove 112, and the bottom wall of the second trapezoidal groove 113 is coplanar with the opening of the first trapezoidal groove. This structure increases the flexibility of the first trapezoidal groove opening while saving material.

[0043] like Figure 6 As shown, in another embodiment of the present invention, the vertical purlin assembly 10 may also not include T-shaped snap-fit profiles. That is, each vertical purlin assembly 10 includes only two vertical profiles 11 and four L-shaped snap-fit profiles 13. In this embodiment, the spacing between the openings of the triangular slots 112 of each vertical profile 11 is relatively small. This results in a relatively small opening width of the first trapezoidal slot formed by the two triangular slots 112 after the two vertical profiles 11 are secured together. That is, the opening width of the first trapezoidal slot formed by the triangular slots 112 of the two vertical profiles 11 is compatible with (i.e., equal to or slightly smaller than) the sum of the thicknesses of the snap-fit edges of the two L-shaped snap-fit profiles 13. Thus, the decorative panel 40 can be secured to the vertical purlin assembly 10 by snapping the snap-fit edges of the two L-shaped snap-fit profiles 13 into the opening of the first trapezoidal slot.

[0044] In one embodiment of the present invention, the decorative panel 40 includes a metal facing 41 and a corrugated core 42 attached to the back of the metal facing 41. The decorative panel 40 is installed on the outside of the insulation layer 20 with the metal facing 41 facing away from the insulation layer 20. This decorative panel 40 can reduce the amount of metal material used while maintaining structural strength, thereby reducing the overall weight of the decorative panel 40.

[0045] like Figure 4 As shown, in one embodiment of the present invention, each insulation layer 20 includes a plurality of parallel horizontal purlins 21 and a gypsum board (not shown) secured between two adjacent horizontal purlins 21. The insulation layer 20 is attached to the vertical purlin assemblies 10 with the ends of the horizontal purlins 21 secured to the adjacent vertical purlin assemblies 10. Specifically, the gypsum board is secured to the horizontal purlins 21 using self-tapping screws. Because the insulation layer 20 is composed of the horizontal purlins 21 and the gypsum board, its structural strength is significantly increased compared to a structure consisting solely of gypsum board.

[0046] In particular, Figure 5 As shown, each transverse keel 21 comprises a main body 211 and transverse wings 212 located above and below the main body 211. The main body 211 and the two transverse wings 212 form an Ω-shaped cross-section. The upper and lower edges of the gypsum board are fixed to the transverse wings 212 of the adjacent transverse keel 21, and the height of the main body 211 protruding from the transverse wings 212 matches the thickness of the gypsum board. This structure ensures a consistent thickness of the insulation layer 20 and facilitates the fixing of the gypsum board.

[0047] Correspondingly, in the vertical profile 11 of the vertical keel assembly 10, vertical flanges 114 are formed on either side of the opening of each rectangular slot 111. The transverse keel 21 is secured to the vertical keel assembly 10 by securing the ends of the transverse flanges 212 to the vertical flanges 114 (e.g., using self-tapping screws). Specifically, after the transverse keel 21 is secured to the vertical flanges 114 of the vertical profile, the gypsum board can be secured to the transverse flanges 212 of the transverse keel 21. This structure greatly facilitates the assembly and securing of the transverse keel 21 to the vertical profile 11.

[0048] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
