DETAILED DESCRIPTION

[0043] The technical solution of the invention is described in detail below with reference to the accompanying drawings:

[0044] Combine Figures 1 to 13 As shown, Example 1 discloses an aluminum alloy decorative component, which mainly includes an aluminum alloy decorative strip 101, an aluminum alloy connecting piece 102 and an aluminum alloy limiting profile 107.

[0045] like Figure 5 and Figure 7As shown, the aluminum alloy decorative strip 101 is a vertical closed-cavity profile, designed with a closed-cavity structure with a rectangular cross-section. Of course, in other embodiments, the closed-cavity structure can also be other shapes, such as semicircular, trapezoidal, elliptical, or any cross-sectional shape designed by the architect. A slot 101A is provided on one side of the rectangular cavity 101D; a spherical limiting hole 101E connected to the slot 101A is also provided at the slot 101A for installing a stainless steel pin 125, which is used to position the upper and lower profiles to ensure the straightness of the two adjacent aluminum alloy decorative strips 101. A slot 101B is provided on the side of the rectangular cavity 101D opposite the slot 101A, and the notches of the slots 101A and 101B are arranged in a corresponding manner. A long hole 101C is also provided on the rectangular cavity 101D, and the long hole 101C is located exactly in the middle of the slot 101B. Mounting holes 101F are further provided on both sides of the slots 101A and 101B for installing stainless steel countersunk self-tapping screws 124 to facilitate fixing the aluminum alloy sealing plates 108 at both ends of the aluminum alloy decorative strip 101 .

[0046] like Figure 6 and Figure 8 As shown, the aluminum alloy connector 102 is a non-planar plate-like structure, primarily consisting of three parts: a connection portion I 102C, a connection portion II 102D, and a connection portion III 102E. The ends of the connection portion III 102E are connected to the connection portion I 102C and the connection portion II 102D, respectively. The connection portions I 102C and II 102D are arranged substantially parallel to each other. A notch 102B is provided at the top of the connection portion I 102C near the connection portion III 102E. A spherical protrusion 102A is provided at the end of the connection portion I 102C to cooperate with the slot 101A. The height of the aluminum alloy connector 102 is adapted to the length of the elongated hole 101C. The surface of the connection portion II 102D of the aluminum alloy connector 102 is provided with a screw hole 102F. A flexible gasket 131 is also provided on the surface of the connection portion I 102C of the aluminum alloy connector 102.

[0047] like Figure 9 As shown, one end of the aluminum alloy limiting profile 107 is designed with a flange 107A, and the shape and size of the flange 107A matches the shape and size of the slot 101B of the aluminum alloy decorative strip 101; the other end is provided with a threaded hole 107B, which is mainly used to install a stainless steel hexagonal cylindrical end set screw 121; the surface where the flange 107A is located is also provided with a screw hole 107C, as shown in FIG. Figure 10 shown.

[0048] Combine Figure 10As shown, during installation and use, the connecting portion 102C of the aluminum alloy connector 102 is inserted into the long hole 101C of the aluminum alloy decorative strip 101, passes through the slot 101B, and then is inserted into the slot 101A. The aluminum alloy connector 102 is then lifted upward and clamped onto the aluminum alloy decorative strip 101 through the notch 102B, thereby securing one end of the aluminum alloy connector 102 within the rectangular cavity 101D of the aluminum alloy decorative strip 101. Furthermore, the aluminum alloy limiting profile 107 is installed below the aluminum alloy connector 102, with the flange 107A inserted into the slot 101B of the aluminum alloy decorative strip 101 and tightly fitting therewith. The aluminum alloy limiting profile 107 is then secured within the rectangular cavity 101D of the aluminum alloy decorative strip 101 by stainless steel hexagon socket head screws 122 sequentially inserted into 101G and 107C, preventing it from sliding. Finally, a stainless steel hexagon socket set screw 121 with a cylindrical end is installed in threaded hole 107B. The threaded hole in threaded hole 107B matches the thread of set screw 121. By adjusting the looseness or tightness of screw 121, the height error of aluminum alloy decorative strip 101 can be adjusted. In this way, the combination of stainless steel hexagon socket set screw 121 with aluminum alloy limiting profile 107 can further prevent the risk of aluminum alloy decorative strip 101 falling off during use.

[0049] Combine Figures 1 to 4 As shown, Example 2 discloses a unit curtain wall with aluminum alloy decorative components, which mainly includes aluminum alloy public columns 103, aluminum alloy female columns 104, aluminum alloy upper crossbeams 105, aluminum alloy lower crossbeams 106, glass panels 401, aluminum alloy cover plates 109, and the aluminum alloy decorative components described in Example 1, wherein the aluminum alloy public columns 103, aluminum alloy female columns 104, aluminum alloy upper crossbeams 105 and aluminum alloy lower crossbeams 106 constitute the main frame of the unit curtain wall.

[0050] like Figure 11 、 Figure 12 As shown, the aluminum alloy male column 103 has a C-shaped groove 103A within its cavity. A slot 103B is provided on the surface connecting to the aluminum alloy decorative component for receiving the aluminum alloy connector 102. During installation, the aluminum alloy decorative component's connecting portion II 102D extends through slot 103B into the C-shaped groove 103A. Stainless steel pan-head machine screw assemblies 123 are installed in screw holes 102F in connecting portion II 102D to secure the aluminum alloy decorative component to the aluminum alloy male column 103. This secures the aluminum alloy connector 102 to the aluminum alloy male column 103 through the C-shaped groove 103A and the associated structure, ensuring it withstands lateral wind loads. A flexible gasket 132 is also provided at the connection between the aluminum alloy decorative component and the column.

[0051] like Figure 1 and Figure 13As shown, the aluminum alloy cover plate 109 arranged on one side of the aluminum alloy public column 103 is located at the position of the aluminum alloy connector 102, and a notch 109A needs to be opened in the factory to facilitate the connection and installation of the aluminum alloy connector 102.

[0052] For the unit curtain wall with aluminum alloy decorative components described in Example 1, the main processing and installation process is as follows:

[0053] In the factory, the aluminum alloy decorative strip 101 is processed separately, including a long hole 101C on the back; the aluminum alloy connecting piece 102 is processed, including a notch 102B; and the aluminum alloy public column 103 is processed, including a long hole 103B.

[0054] After processing is completed, the aluminum alloy connector 102 is inserted into the long hole 103B of the aluminum alloy public column 103 and fixed by the stainless steel pan head machine screw assembly 123; then the main frame of the unit curtain wall is assembled, and the glass panels and other components are installed to complete the assembly of the unit curtain wall.

[0055] After the unit curtain wall is assembled, the long hole 101C of the aluminum alloy decorative strip 101 is inserted into the aluminum alloy connector 102, and the position is moved so that the notch 102B clamps the aluminum alloy decorative strip 101; the flange 107A of the aluminum alloy limiting profile 107 is slid into the slot 101B of the aluminum alloy decorative strip 101, and the stainless steel hexagon socket cylindrical head screw 122 is installed, and the stainless steel hexagon socket cylindrical end set screw 121 is installed to adjust the position of the aluminum alloy decorative strip 101; at this point, the assembly of the unit curtain wall with aluminum alloy decorative components is completed.

[0056] Finally, it will be Figure 3 The assembled unit curtain wall with aluminum alloy decorative components shown is transported to the site, and the unit panels can be hoisted on site.

[0057] Based on Example 2, the present invention can further optimize the connection method between the aluminum alloy connector and the aluminum alloy public column. The aluminum alloy connector is connected to the outer wall of the aluminum alloy public column to avoid opening a long hole on the front of the aluminum alloy column. Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, Example 3 discloses another unitized curtain wall with aluminum alloy decorative components. The aluminum alloy public column 203 is designed with a notch 203B, and a stainless steel spacer 227 is positioned within the notch 203B. Screw holes are provided on the wall of the aluminum alloy public column 203 adjacent to the notch 203B, and corresponding screw holes are also provided on the stainless steel spacer 227. A notch 203A is partially provided on the aluminum alloy public column 203 at the location of the aluminum alloy connector 202. After the aluminum alloy connector 202 is inserted into the notch 203A, stainless steel countersunk screws 226 secure the aluminum alloy connector 202 to the stainless steel spacer 227 and the aluminum alloy public column 203.

[0058] Based on Example 2, the present invention can also optimize the limiting and adjusting methods of the aluminum alloy decorative strip. Figures 18 to 20 As shown, Example 4 discloses another unitized curtain wall with aluminum alloy decorative components. The bottom of the slot 301A of the aluminum alloy decorative strip 301 is factory-machined with a threaded hole 301B, whose thread specifications match those of a stainless steel hexagon socket cylindrical set screw 321. This allows the stainless steel hexagon socket cylindrical set screw 321 to directly control the position of the aluminum alloy decorative strip 301, preventing it from falling off, thus eliminating the need for a retaining profile.

[0059] In summary, the decorative strip connection structure disclosed in the present invention ensures the safety of the decorative strip through mechanical connection, avoids the risk of falling off of the traditional decorative strip buckle cover, eliminates the joints between the traditional decorative strip and the buckle cover, and improves the appearance quality.
