[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0036] This embodiment discloses an irregularly shaped curtain wall and its installation structure. Here, "irregularly shaped" refers to the hyperbolic decorative line shape formed after installation. Each irregularly shaped curtain wall adopts a modular design, prefabricated and assembled in the factory, and then transported to the construction site. The complete hyperbolic decorative line curtain wall is formed by assembling and fixing the irregularly shaped curtain walls together. The modular irregularly shaped curtain wall is designed according to its shape and installation location. In this embodiment, it is divided into two types of modular units, one of which is as follows: Figure 4 and Figure 5 The vertical module unit 1 shown is another type, as shown in the figure. Figure 9 The horizontal module unit 2 shown is formed by integrating a three-dimensional skeleton and a panel.

[0037] The structure of vertical module unit 1 is as follows: Figures 4 to 6 As shown, a three-dimensional frame is formed by assembling the first diagonal brace 12, the first horizontal brace 13, and the first vertical brace 14. A first panel 11 is then covered on the outer surface of the three-dimensional frame. In this embodiment, the first panel 11 is a single-layer aluminum plate. The three-dimensional frame of the vertical module unit 1 is as follows: Figures 1 to 3 As shown, a rectangular frame structure is formed by fixing two upper and lower first horizontal keels 13 and two left and right first vertical keels 14 together. At the upper and lower ends of the rectangular frame structure, two first diagonal bracing keels 12 connect the end faces to form a triangle. Multiple sets of first diagonal bracing keels 12 can be spaced apart in the middle of the rectangular frame and connected to the first vertical keels 14 to form a triangular cross-section. For each set of two first diagonal bracing keels 12 in the middle of the rectangular frame, as shown... Figure 3 As shown, the connecting ends of the two first diagonal bracing keels 12 are fixed together by first aluminum alloy end connectors 16 and screws. The other ends of the two first diagonal bracing keels 12 are each fixed to the first vertical keel 14 by L-shaped aluminum alloy side connectors 15 and screws. For the two ends of the rectangular frame, as shown... Figure 1 and Figure 2 As shown, the connecting ends of the two first diagonal bracing keels 12 are also fixedly connected together by the first aluminum alloy end connector 16 and screws. The two ends of the first transverse keel 13 are fixedly connected to the first vertical keel 14 by the L-shaped aluminum alloy side connector 15 and screws. The two ends of the first transverse keel 13 are also fixedly connected to the inner side wall of the first diagonal bracing keel 12 by the L-shaped aluminum alloy connector 15 and screws.

[0038] Following the above, as Figure 1As shown, the three-dimensional skeleton of the vertical module unit 1 is long vertically and narrow horizontally. The first vertical keel 14 forms a continuous vertical groove 141 on the side facing the first diagonal brace 12, and the first horizontal keel 13 forms a continuous horizontal groove 131 on the side facing the first diagonal brace 12. The first panel 11 is a single piece of aluminum plate, with its middle part bent to form a bending angle consistent with the included angle of the two first diagonal braces 12, so that the first panel 11 can cover the outer surface of the three-dimensional skeleton formed by the first vertical keel 14 and the first diagonal brace 12. To enhance the support of the first panel 11, a first aluminum alloy sub-frame 17 is provided on the inner side of the first panel 11. The left and right edges and the top and bottom edges of the first panel 11 are all bent, and their bending direction is towards the inside of the three-dimensional skeleton. The bent structures at the top and bottom of the first panel 11 are fixed to the outer surface of the first horizontal keel 13, and the bent structures on the left and right sides of the first panel 11 are fixed to the vertical grooves 141 of the first vertical keel 14.

[0039] The structure of the horizontal module unit 2 is similar to that of the vertical module unit 1, with... Figure 9 With the indicated direction as a reference, the upper and lower second horizontal keels 23 are connected to the left and right second vertical keels 24 to form a rectangular frame. The three-dimensional skeleton of the horizontal module unit 2 is long horizontally and narrow vertically. According to design requirements, the length of the three-dimensional skeleton of the horizontal module unit 2 is shorter than that of the three-dimensional skeleton of the vertical module unit 1. Therefore, the three-dimensional skeleton in the horizontal module unit 2 can only have two second diagonal bracing keels 22 at each of the left and right ends. The connecting ends of the two second diagonal bracing keels 22 are fixedly connected by second aluminum alloy end connectors 28 and screws, so that the ends of the three-dimensional skeleton form a triangle. The connection method of the second diagonal bracing keel 22, the second vertical keel 24, and the second horizontal keel 23 in the horizontal module unit 2 can be set with reference to the above-mentioned vertical module unit 1, and is omitted here. The panel in the horizontal module unit 2 is the second panel 21. The second panel 21 is also made of a single-layer aluminum plate. The inner side of the second panel 21 is also supported by the second aluminum alloy sub-frame 27. The middle part of the second panel 21 is bent, and its bending angle is consistent with the included angle of the two second diagonal bracing keels 22. The upper and lower ends and the left and right edges of the second panel 21 are also bent towards the inside of the three-dimensional frame. The second panel covers the two outer surfaces enclosed by the second horizontal keel 23 and the second diagonal bracing keel 22. The upper and lower bending structures of the second panel 21 are respectively fixed to the outer surface of the second horizontal keel 23, and the left and right bending structures of the second panel 21 are fixed to the outer surface of the second diagonal bracing keel 22. In this embodiment, the panels can all be fixed to the three-dimensional frame by fasteners.

[0040] In this embodiment, the installation positions and installation structures of the vertical module unit 1 and the horizontal module unit 2 are different. To facilitate the installation of the horizontal module unit 2, as follows: Figure 9As shown, in the transverse module unit 2 of the embodiment, the two ends of the second transverse keel 23 at the upper end are respectively fixedly installed with aluminum alloy upper hanging pieces 25, and the two ends of the second transverse keel 23 at the lower end are respectively fixedly installed with aluminum alloy lower hanging pieces 26. The aluminum alloy upper hanging pieces 25 and the aluminum alloy lower hanging pieces 26 are both installed on the same side of the second transverse keel 23. The structure of the aluminum alloy upper hanging piece 25 is as shown in Figure 10 As shown, the cross-sectional structure of the aluminum alloy upper hanging piece 25 is in the shape of a Z letter, and the aluminum alloy upper hanging piece 25 can be divided into a first connecting plate 251, a second connecting plate 252 and a third connecting plate 253 connected in sequence. The first connecting plate 251 and the third connecting plate 253 are both provided with a fixing hole, and the third connecting plate 253 is fixed on the second transverse keel 23 at the upper end by a rivet, so that the first connecting plate 251 extends upward beyond the top surface of the second transverse keel 23. Figure 11 As shown, the cross-sectional structure of the aluminum alloy lower hanging piece 26 is in the shape of a hook-shaped stick, and the aluminum alloy lower hanging piece 26 can be divided into a straight main connecting part 261 and an arc-shaped connecting part 262 with a curved arc. Figure 11 As shown in the direction for reference, the arc-shaped connecting part 262 is bent downward to form an arc-shaped groove 263 with an open lower part, the left end of the arc-shaped connecting part 262 is a free end, and the right end of the arc-shaped connecting part 262 is integrated with the top end of the main connecting part 261. On the connecting section of the arc-shaped connecting part 262 and the main connecting part 261, a second limiting part 265 perpendicular to the main connecting part 261 is formed on the left side, and a first limiting part 264 perpendicular to the main connecting part 261 is formed on the right side. The first limiting part 264 is higher than the second limiting part 264, and a hole is opened on the main connecting part 261 below the second limiting part 265. As shown, Figure 13 The main connecting part 261 is fixed on the second transverse keel 23 at the lower end by a rivet, and at this time, the first limiting part 264 is clamped on the top end of the second transverse keel 23. In order to facilitate the up-down position adjustment of the transverse module unit 2 during installation, a threaded hole is also opened on the arc-shaped connecting part 262 in the embodiment, and a height adjustment bolt 6 is installed.

[0041] The vertical module unit 1 and the transverse module unit 2 given above are used to form a double-curved decorative line curtain wall by being spliced respectively. The installation structure of the double-curved decorative line curtain wall is as follows: the installation of the vertical module unit 1 is as shown in Figure 7 and Figure 8As shown, the vertical module units 1 are arranged with left and right spacing, and glass curtain walls are installed between the vertical module units 1. Taking the mounting structure of a single vertical module unit 1 as an example, the first vertical keel 14 at the left and right ends of the vertical module unit 1 is fixedly connected to the corresponding side of the aluminum alloy stand column 3 through screws. Since the first vertical keel 14 is provided with a vertical groove 141, adjustment space is provided for the left and right positioning of the vertical module unit 1. After the positioning and adjustment are completed, the first vertical keel 14 is fixed to the aluminum alloy stand column 3 through screws. The first horizontal keel 13 is fixedly connected to the aluminum alloy cross beam 4 through screws. Since the first horizontal keel 13 is provided with a horizontal groove 131, adjustment space is provided for the up and down positioning of the vertical module unit 1. After the positioning and adjustment are completed, the first horizontal keel 13 is fixed to the aluminum alloy cross beam 4 through screws.

[0042] As described above, the mounting structure of the horizontal module unit 2 is as shown in Figure 12 and Figure 13 As shown, in addition to the hyperbolic decorative lines formed by the vertical module units 1 and the horizontal module units 2, glass curtain walls are also installed on the aluminum alloy stand columns 3 and the aluminum alloy cross beams 4. The installation mode of the glass curtain walls can be assembled according to the prior art, or the structure shown in Figure 7 can be used for assembly. The installation of the glass curtain wall is not the technical improvement point of the present application, and therefore the introduction is omitted. The installation of the glass curtain wall involves the curtain wall fixing device 5. In the present embodiment, the horizontal module unit 2 is connected to the curtain wall fixing device 5. As shown in Figure 13 The structure of the curtain wall fixing device 5 includes a main body portion, the cross section of the main body portion is rectangular, a hollow cavity is formed in the inside, and a hole is opened on the side wall of the main body portion facing the outside, so that Figure 13 As a reference, an extension rod is obliquely extended upward from the upper right corner of the main body portion, the bottom end of the extension rod is integrated with the main body portion, and the top end of the extension rod forms a spherical structure. In the present embodiment, the upper and lower ends of each horizontal module unit 2 correspond to a curtain wall fixing device 5. Taking the same curtain wall fixing device as a reference, in the two horizontal module units 2 adjacent to each other, the first connecting plate 251 of the aluminum alloy upper hanging piece 25 on the lower horizontal module unit 2 is fixed to the main body portion of the curtain wall fixing device 5 through a bolt; the arc-shaped connecting portion 262 of the aluminum alloy lower hanging piece 26 on the upper horizontal module unit 2 is hung on the spherical structure of the curtain wall fixing device 5, the spherical structure is located in the arc-shaped groove 263, so that the horizontal module unit 2 can be adjusted in position by 360° around the spherical structure, and the second limiting portion 265 on the aluminum alloy lower hanging piece 26 can effectively prevent the spherical structure from being pulled out of the arc-shaped groove 263. Since the height adjusting bolt 6 is installed on the aluminum alloy lower hanging piece 26, the height of the horizontal module unit 2 can be adjusted by rotating the height adjusting bolt 6.

[0043] The vertical module unit 1 and the horizontal module unit 2 can be positioned and adjusted during assembly, and the installation precision of the curtain wall is improved.

[0044] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
