In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] like Figure 1 to Figure 4 As shown, this embodiment provides an external wall panel 1000, which includes a bracket assembly 100, a decorative layer 200 and an insulation layer 300. The bracket assembly 100 is used to connect with the wall 2000, where the wall 2000 can be a steel structure wall 2000, a concrete wall 2000 or a brick wall, which is not limited in this embodiment. At least part of the bracket assembly 100 is parallel to and spaced apart from the bracket assembly 100, so that a receiving space is formed between the decorative layer 200 and the bracket assembly 100, and the decorative layer 200 is connected to the bracket assembly 100, and the insulation layer 300 is arranged in the receiving space, thereby fixing the insulation layer 300. The external wall panel 1000 uses the decorative layer 200 to fix the insulation layer 300, and does not require a prefabricated template, which is conducive to simplifying the processing steps of the external wall panel 1000, saving costs, and is easy to operate, which is conducive to improving processing efficiency. At the same time, the decorative layer 200 is formed by 3D printing, and the 3D printed texture is used for decorative effect. Compared with the existing technology, the cost of directly using tiles is reduced, and users do not need to perform additional surface treatment, which is conducive to cost saving.

[0050] Specifically, see Figure 1 and Figure 2 The bracket assembly 100 includes at least two horizontal frames 110 and at least two vertical frames 120. The at least two horizontal frames 110 extend along the X direction, and along the Y direction, at least two horizontal frames 110 are arranged in parallel and spaced apart. The at least two vertical frames 120 extend along the Y direction, and along the X direction, at least two vertical frames 120 are arranged in parallel and spaced apart. The horizontal frame 110 is connected to each vertical frame 120, and the decorative layer 200 is connected to the horizontal frame 110 and / or the vertical frame 120. The number of specific horizontal frames 110 and vertical frames 120 can be determined according to the size of the external wallboard 1000. When the size of the external wallboard 1000 is small, two horizontal beams and two vertical beams are arranged to form a rectangular or square frame-shaped bracket assembly 100. Of course, when the size of the external wallboard 1000 is large, the number of horizontal beams and vertical beams gradually increases. In this embodiment, the horizontal beams and vertical beams can be square tubes or round tubes. Both square tubes and round tubes are commonly used bracket structures, which are easy to purchase and low in cost. Preferably, the cross beam and the number are preferably square tubes, because each side of the square tube is a plane structure, which facilitates the connection and fixation of the cross beam and the vertical beam, and facilitates the cross beam or the number to be fixed on the wall 2000. Furthermore, the surface of the cross beam and the vertical beam is galvanized to prevent the bracket assembly 100 from rusting, which is beneficial to improve the service life of the bracket assembly 100.

[0051] As an alternative, Figure 3As shown, the external wall panel 1000 also includes a second fixing assembly 500, which is used to connect the bracket assembly 100 and the wall 2000. Specifically, the second fixing assembly 500 includes a second fixing portion 520 and at least one first fixing portion 510. The first fixing portion 510 is connected to the bracket assembly 100 through a fixing member 600, the second fixing portion 520 is perpendicular to the first fixing portion 510, and the second fixing portion 520 is connected to the wall 2000 through the fixing member 600, so that it is convenient for users to fix and connect the bracket assembly 100 and the wall 2000. Optionally, the fixing member 600 is a screw, a pin or a rivet, etc., and the screw, the pin and the rivet are all conventional connectors, which are easy to purchase and easy for users to operate.

[0052] When there is one first fixing portion 510 , one first fixing portion 510 is connected to the second fixing portion 520 in an L-shape, and the L-shaped second fixing component 500 is a conventional connection structure, which is convenient for user operation.

[0053] In this embodiment, there are two first fixing parts 510, and the two first fixing parts 510 are arranged in parallel and at intervals. When the second fixing assembly 500 is used to fix the cross beam and the wall 2000, the horizontal frame 110 is located in the interval between the two first fixing parts 510. When the second fixing assembly 500 is used to fix the vertical beam and the wall 2000, the vertical frame 120 is located in the interval between the two first fixing parts 510. The structure of the second fixing assembly 500 can use the two first fixing parts 510 to simultaneously constrain the side of the cross beam or the vertical beam, which is conducive to improving the stability of the connection. More preferably, at this time, the two first fixing parts 510 are vertically connected to the middle of the second fixing part 520, and space is still reserved at both ends of the second fixing part 520 to facilitate the connection with the wall 2000. At this time, there are multiple second fixing assemblies 500, and multiple second fixing assemblies 500 are used to fix the bracket assembly 100 and the wall 2000, thereby strengthening the stability of the connection between the external wall panel 1000 and the wall 2000.

[0054] Of course, when there are more first fixing parts 510, the length of the second fixing parts 520 increases accordingly. Multiple first fixing parts 510 are arranged in parallel and at intervals, and two of the multiple first fixing parts 510 are grouped together. Each group of first fixing parts 510 fixes both sides of the horizontal beam or the vertical beam respectively, so that along the extension direction of the second fixing parts 520, multiple groups of first fixing parts 510 simultaneously fix multiple horizontal beams or multiple vertical beams, thereby enhancing the stability of the connection between the external wall panel 1000 and the wall 2000.

[0055] It is understandable that the 3D printed decorative layer 200 is printed layer by layer and stacked layer by layer by a 3D printing device. Furthermore, the 3D printing device can be printed along the X direction (first direction) and then stacked layer by layer along the Y direction (second direction), where the X direction is parallel to the bottom surface and the Y direction is perpendicular to the ground. In this embodiment, after the 3D printing is completed, the decorative layer 200 is set on the bracket assembly 100 in the above-mentioned printing direction, so that the extension direction of its striped texture is the X direction. Of course, the user can also rotate the decorative layer 200 90° and set it on the bracket assembly 100. At this time, the extension direction of the striped texture of the decorative layer 200 will become the Y direction. In this embodiment, both of the above two assembly methods are applicable, and this embodiment is not limited to this.

[0056] Optionally, see Figure 1 and Figure 2 The decoration layer 200 includes at least two decoration walls 210 and at least one connection part 220. The at least two decoration walls 210 are parallel to the support assembly 100 and are arranged at intervals. When the 3D printer prints the decoration layer 200 along the X direction, the at least two decoration walls 210 are arranged along the X direction. When the 3D printer prints the decoration layer 200 along the Y direction, the at least two decoration walls 210 are arranged along the Y direction. The connection part 220 is arranged between two adjacent decoration walls 210. The connection part 220 protrudes toward the support assembly 100. The connection part 220, the decoration wall 210 and the support assembly 100 are surrounded to form an accommodating space, thereby achieving a double-layer effect of fixing the insulation board and the decoration.

[0057] Specifically, the decorative wall 210 and the connecting portion 220 are an integrated structure. When the decorative layer 200 is 3D printed, the 3D printing device prints the decorative wall 210 and the connecting portion 220 alternately, thereby reducing the printing path of the 3D printing process, which is beneficial to improving printing efficiency.

[0058] The external wall panel 1000 also includes a plurality of first fixing components 400. When the 3D printer prints the decorative layer 200 along the X direction, the plurality of first fixing components 400 are arranged in parallel and at intervals along the Y direction. When the 3D printer prints the decorative layer 200 along the Y direction, the plurality of first fixing components 400 are arranged in parallel and at intervals along the X direction. The first fixing components 400 can fix the decorative layer 200 and the bracket component 100, thereby facilitating the fixed connection between the decorative layer 200 and the bracket component 100 and enhancing the structural strength of the decorative layer 200.

[0059] When preparing the external wall panel 1000, the decorative layer 200 is first 3D printed. After printing the decorative layer 200 of a preset height, a first fixing component 400 can be laid, and then the decorative layer 200 is continued to be printed, so that the first fixing component 400 is buried in the decorative layer 200, and then the above process is repeated, so that the printing of the decorative layer 200 and the pre-embedding of the first fixing component 400 can be completed. After the decorative layer 200 is printed, the user only needs to put the insulation layer 300 into the reserved accommodation space of the decorative layer 200, and then assemble the first fixing component 400 and the bracket component 100, which is convenient and quick to install.

[0060] See also Figure 4 The first fixing assembly 400 includes an embedded rod 410 and a plurality of connecting rods 420. The embedded rod 410 is embedded in the decorative layer 200, and the plurality of connecting rods 420 are connected to the embedded rod 410, and the plurality of connecting rods 420 are all connected to the bracket assembly 100, which can improve the connection strength between the first fixing member 600 and the bracket assembly 100, thereby improving the connection strength between the decorative layer 200 and the bracket assembly 100, and improving the structural stability and safety of the external wallboard 1000.

[0061] Furthermore, a mounting hole is opened on the bracket assembly 100 , and the connecting rod 420 passes through the mounting hole and fixes the decorative layer 200 on the bracket assembly 100 , which is easy to operate and helps to improve the processing efficiency of the external wall panel 1000 .
