It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" used below are consistent with the upper and lower directions in the drawings, but this should not be construed as a limitation of the technical solution of the present invention.

[0018] This embodiment takes the construction of the free-curvature aluminum panel curtain wall at the eaves and fisheye area of ​​Jiaxing Nanhu Future Plaza as an example. The following section combines... Figure 1 and Figure 2 This utility model describes a large-format free-curvature decorative structure, comprising: a support frame 30, multiple decorative panels 10, and multiple corner brackets 20. Each decorative panel 10 includes a curved decorative panel 11 and a folded edge 12 that surrounds and connects the edge of the curved decorative panel 11. The curved decorative panel 11 is formed by stamping multiple curved unit models obtained by cutting the three-dimensional model of the free-curvature aluminum panel curtain wall through the outer decorative panel dividing line. Multiple corner brackets 20 are spaced apart along the folded edge 12. The corner brackets 20 are positioned between two adjacent decorative panels 10. One side of the corner bracket 20 is connected to the folded edge 12 of two adjacent decorative panels 10, and the other side is detachably connected to the support frame 30. The support frame 30 is connected to the main building structure 1.

[0019] This utility model discloses a large-format, free-curvature decorative structure, comprising a support frame 30, multiple decorative panels 10, and multiple corner bracket fasteners 20. Each decorative panel 10 includes a curved decorative plate 11 and a folded edge 12 that surrounds and connects the edges of the curved decorative plate 11. The curved decorative plate 11 is formed by stamping multiple curved unit models obtained by cutting the three-dimensional model of the free-curvature aluminum panel curtain wall through the outer decorative surface dividing lines. The corner bracket fasteners 20 are disposed between two adjacent decorative panels 10, with one side of each corner bracket fastener connected to the folded edge 12 of the two adjacent decorative panels 10, and the other side being detachable. Connected to the support frame 30; the ultra-large free curvature decorative structure has folded edges 12 surrounding and connecting the edges of each curved decorative panel 11, and corner bracket connectors are set between the folded edges 12 of two adjacent curved decorative panels 11. The corner bracket connectors realize the detachable connection between two adjacent curved decorative panels 11 and the support frame 30, so that the decorative structure spliced ​​by multiple decorative panels 10 can be consistent with the shape of the three-dimensional model of the free curvature aluminum panel curtain wall, reducing the processing and installation difficulty of the ultra-large free curvature decorative structure, and improving the installation accuracy of the assembly position of the irregular curved decorative panels 10.

[0020] like Figure 2 As shown, the corner bracket fastener 20 has an L-shaped cross-section and is embedded in the gap between two adjacent decorative panels 10. One side plate of the corner bracket fastener 20 is connected to the decorative panel 10 by rivets, and the other side plate is threaded to the support frame 30 by self-tapping screws. Furthermore, a washer 21 is provided between the corner bracket fastener 20 and the support frame 30 to prevent the corner bracket connector from loosening. The washer 21 can be made of materials such as metal, rubber, or silicone.

[0021] like Figure 1 As shown, the installation directions of two adjacent corner brackets 20 are opposite, which makes the stress distribution of the two adjacent decorative panels 10 more uniform, avoiding excessive stress on one side of the decorative panel 10, which could lead to deformation or damage. Moreover, this installation method can also effectively resist torsional force, making the entire decorative structure more stable.

[0022] like Figure 1 As shown, the inner side of the decorative panel 10 near the support frame 30 is also provided with a plurality of spaced reinforcing ribs 14 to enhance the structural strength of the decorative panel 10. The reinforcing ribs 14 are made of steel profiles.

[0023] like Figure 1 and Figure 2As shown, since the curved decorative panel 11 with irregular curved surface cannot be folded using the folding machine 12, the long side of the folding edge 12 is derived from the curve shape of each side derived from the curved unit model and is cut from a flat aluminum plate. Each folding edge 12 is vertically set and welded to the edge of the corresponding curved decorative panel 11. The width of the folding edge 12 is 20mm, which facilitates the installation of corner bracket fasteners 20 on the folding edge 12.

[0024] like Figure 2 As shown, the support frame 30 is a frame structure formed by connecting longitudinally arranged square steel pipes 31 and transversely arranged angle steel 35. Multiple steel angle brackets 32 are welded to the square steel pipes 31. The ends of the steel angle brackets 32 and angle steel 35 are provided with a pair of elongated holes 36 with corresponding number and position. The ends of the steel angle brackets 32 and angle steel 35 are locked and fixed by bolts passing through the elongated holes 36.

[0025] Please continue to refer to this. Figure 2 The large-format, free-curvature decorative structure also includes a sealing strip, which comprises a foam rod 41 or a wooden strip embedded in the gap between two adjacent decorative panels 10, and a weather-resistant sealant 42 sealed on its outer side. To prevent the spliced ​​decorative panels 10 from loosening, clamps (not shown in the figure) are also provided at the inner folded edges 12 of the two adjacent decorative panels 10.

[0026] The following is combined with Figure 1 and Figure 2 The construction process of the ultra-large panel with free curvature of this utility model is described below, with specific steps as follows:

[0027] S1: A free curvature aluminum panel curtain wall 3D model is obtained by using Rhino software for proportional 3D modeling. The free curvature aluminum panel curtain wall 3D model is divided into multiple curved unit models according to the outer surface division line. Each curved unit model is offset by 7.5mm to both sides of the outer surface division line as the reserved aluminum panel glue joint width. The outer surface division line is set in combination with the installation and construction requirements and decorative effect.

[0028] S2: Import the curved unit model into the CNC machining tool in sequence. The dot matrix punch of the CNC machining tool arranges the curved shape to match the curved unit model. The flat aluminum plate is stamped to form a curved decorative plate 11 that matches the curved unit model. The stamped curved decorative plate 11 is digitally scanned and compared with the curved unit model. For areas where the stamping is not in place due to the springback of some punches, the punches are deepened and adjusted until the curved decorative plate 11 after stamping can match the shape of the curved unit model.

[0029] S3: Based on the curve shape of each edge derived from the curved unit model, cut and process the folded edge 12 on a flat aluminum plate with the same thickness as the curved decorative plate 11. The width of the folded edge 12 is 20mm. Multiple folded edges 12 are sequentially attached and welded to the edge of the corresponding curved decorative plate 11. After the folded edge 12 is welded and polished, multiple corner bracket fasteners 20 are fixed to the folded edge 12 with rivets at the specified spacing.

[0030] S4: At the factory, 3 to 5 decorative panels 10 that have passed digital scanning are trial-assembled to check the smoothness of the decorative panels 10. Areas with uneven splicing are rechecked and adjusted. This process is repeated until all decorative panels 10 can be smoothly spliced. Then, they are transported to the construction site. At the construction site, the support frame 30 and the decorative panels 10 are assembled in sequence. The glue joint width between the decorative panels 10 is 15mm. Foam rods 41 are embedded in the gap between two adjacent decorative panels 10, or 15mm wide wooden strips are used to pad the gap between two adjacent decorative panels 10. The outside of the strips is sealed with silicone weather-resistant sealant 42. At the same time, the side of the folded plate of two adjacent decorative panels 10 that is close to the support frame 30 is clamped with clamps to prevent the adjacent decorative panels 10 from loosening.

[0031] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the claims.
