Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, and more specifically to an installation structure for a hyperbolic decorative line curtain wall. Background Technology

[0002] The application of irregularly shaped curtain walls in contemporary architectural design is becoming increasingly widespread. Currently, for complex irregularly shaped curtain walls, due to their highly irregular shapes, their processing and construction are mainly carried out through component-based curtain wall production and installation. This involves processing components such as connectors, keels, and panels in the factory, transporting them to the construction site, and then, according to the architectural design requirements, conducting surveying and layout work before installing each component one by one. The control of the appearance effect of irregularly shaped curtain walls largely depends on the technical level of the workers and their individual quality awareness. Furthermore, the processing and installation process of complex irregularly shaped curtain walls is more complicated than that of conventional curtain walls. Therefore, this approach in current technology often leads to difficulties in controlling the processing and installation accuracy and construction progress of irregularly shaped curtain walls, affecting project schedules, and resulting in an appearance effect far removed from the architectural design requirements. Summary of the Invention

[0003] This invention discloses an installation structure for a hyperbolic decorative line curtain wall. The vertical and horizontal module units are prefabricated in the factory using a modular design concept, allowing for convenient and quick assembly on the construction site. The structure also allows for positioning and adjustment during installation, resulting in high assembly efficiency and high installation accuracy.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An installation structure for a hyperbolic decorative line curtain wall includes vertical module units, horizontal module units, aluminum alloy columns, aluminum alloy beams, a glass curtain wall, and curtain wall fixing devices for fixing the glass curtain wall. Both the vertical and horizontal module units include a three-dimensional frame and panels mounted on the frame. The three-dimensional frame of the vertical module unit is vertically long and horizontally narrow, while the three-dimensional frame of the horizontal module unit is vertically narrow and horizontally wide. The cross-section of the three-dimensional frame is triangular, and the panels cover the exterior facade containing two adjacent sides of the triangle in the three-dimensional frame. The aluminum alloy beams are fixedly connected to the aluminum alloy columns. Multiple vertical modular units are arranged side-by-side with intervals between them. Glass curtain walls are installed between adjacent vertical modular units. The glass curtain walls are installed on aluminum alloy columns and aluminum alloy beams through curtain wall fixing devices. The three-dimensional frame of the vertical modular units is fixedly connected to the aluminum alloy columns and aluminum alloy beams with screws. Aluminum alloy hangers are installed at the upper and lower ends of the three-dimensional frame of the horizontal modular units. Multiple horizontal modular units are spliced ​​together vertically. Each splice point of two adjacent horizontal modular units corresponds to a curtain wall fixing device. The horizontal modular units are fixed to the corresponding curtain wall fixing devices through aluminum alloy hangers.

[0006] Furthermore, the curtain wall fixing device includes a main body with an opening. The main body extends outward toward the side of the horizontal module unit to form an extension rod. The top of the extension rod forms a spherical structure. The upper part of the three-dimensional frame of the horizontal module unit is an aluminum alloy upper hanger, and the lower part of the three-dimensional frame is an aluminum alloy lower hanger. The aluminum alloy upper hanger is fixed to the main body of the curtain wall fixing device by bolts, and the aluminum alloy lower hanger is attached to the spherical structure of the curtain wall fixing device. The aluminum alloy lower hanger can move around the spherical structure.

[0007] Furthermore, the aluminum alloy upper bracket includes a first connecting plate, a second connecting plate, and a third connecting plate connected in sequence. The cross-section of the first connecting plate, the second connecting plate, and the third connecting plate after connection forms a Z-shape. Fixing holes are provided on both the first connecting plate and the third connecting plate. The third connecting plate is fixed to the three-dimensional frame of the horizontal module unit by rivets. The first connecting plate extends out of the top surface of the three-dimensional frame and is fixed to the main body of the curtain wall fixing device by bolts.

[0008] Furthermore, the aluminum alloy lower bracket includes a straight main connecting part and an arc-shaped connecting part with a curved arc. The main connecting part has an opening and is fixed to the three-dimensional frame of the horizontal module unit by rivets. The arc-shaped connecting part forms an open arc-shaped groove and is hung on the spherical structure of the curtain wall fixing device, so that the spherical structure is embedded in the arc-shaped groove.

[0009] Furthermore, a through threaded hole is provided on the arc-shaped connecting part, and a height adjustment bolt is installed in the threaded hole.

[0010] Furthermore, on the connecting section between the main connecting part and the arc-shaped connecting part, a second limiting part is provided on the side facing the spherical structure, and a first limiting part is provided on the side away from the spherical structure. Both the first limiting part and the second limiting part are perpendicular to the main connecting part. The first limiting part limits the three-dimensional skeleton, and the second connecting part limits the spherical structure.

[0011] Furthermore, the panel is made of a single layer of aluminum plate.

[0012] Furthermore, the three-dimensional frame of the vertical module unit includes a first diagonal brace, a first horizontal brace, and a first vertical brace. Two first horizontal braces are connected to two first vertical braces to form a rectangular frame. The first horizontal brace at each end is connected to two first diagonal braces to form a triangular cross section perpendicular to the plane of the rectangular frame. Multiple sets of first diagonal braces are provided in the middle of the two first vertical braces. Two first diagonal braces are provided in each set and they intersect and connect with each other. A first panel is installed on the outer facade enclosed by the first vertical braces and the first diagonal braces. A continuous vertical groove is formed on each of the two first vertical braces. A continuous horizontal groove is formed on each of the upper and lower first horizontal braces. The side of the first panel forms a side fold, which is fixed in the vertical groove.

[0013] Furthermore, the first horizontal keel is connected to the first vertical keel by screws through an L-shaped aluminum alloy side connector. The connecting ends of the two intersecting first diagonal bracing keels are fixedly connected by screws through first aluminum alloy end connectors. The other end of the first diagonal bracing keel is connected to the first vertical keel and / or the first horizontal keel respectively by screws through an L-shaped aluminum alloy side connector. The inner side of the first panel is provided with a first aluminum alloy sub-frame, and the first panel is fixedly connected to the first aluminum alloy sub-frame by bolts.

[0014] Furthermore, the three-dimensional frame of the horizontal module unit includes a second diagonal brace, a second horizontal keel, and a second vertical keel. Two second horizontal keels and two second vertical keels are connected to form a rectangular frame. The second vertical keel at each end is connected to two second diagonal braces to form a triangular cross section perpendicular to the plane of the rectangular frame. An aluminum alloy upper hanger is installed on the upper second horizontal keel, and an aluminum alloy lower hanger is installed on the lower second horizontal keel. A second panel is installed on the outer facade enclosed by the second horizontal keel and the second diagonal brace.

[0015] This invention forms a hyperbolic decorative curtain wall by installing vertical and horizontal modular units. Both the vertical and horizontal modular units adopt a modular design, integrating the three-dimensional frame with the panel and prefabricating it in the factory, which improves the assembly efficiency and installation accuracy of the curtain wall. Furthermore, the installation structure of the designed vertical and horizontal modular units can be positioned and adjusted during installation, providing construction convenience for the assembly of the curtain wall.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] This embodiment discloses an installation structure for a hyperbolic decorative line curtain wall. After installation, the curtain wall forms a hyperbolic decorative line shape. A modular design approach is adopted, forming vertical module unit 1 and horizontal module unit 2. The module units are prefabricated and assembled in the factory and then transported to the construction site. The complete hyperbolic decorative line curtain wall is formed by assembling the module units. Both vertical module unit 1 and horizontal module unit 2 are designed based on the double-sided line shape. The structure of vertical module unit 1 is as follows: Figure 4 and Figure 5 As shown, the structure of the horizontal module unit 2 is as follows: Figure 9 As shown, both types of modular units are formed by integrating a three-dimensional skeleton and a panel.

[0038] 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.

[0039] 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, the middle of which is 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, and the first panel 11 is fixed to the first aluminum alloy sub-frame 17 by bolts. The left and right edges and the top and bottom edges of the first panel 11 are all bent, and the bending direction is towards the inside of the three-dimensional frame. The bent structure at the top and bottom of the first panel 11 is fixed to the outer surface of the first horizontal keel 13, and the bent structure on the left and right sides of the first panel 11 is fixed to the vertical groove 141 of the first vertical keel 14.

[0040] 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.

[0041] 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 9 As shown, in the horizontal module unit 2 of this embodiment, aluminum alloy upper hangers 25 are fixedly installed at both ends of the upper second horizontal keel 23, and aluminum alloy lower hangers 26 are fixedly installed at both ends of the lower second horizontal keel 23. Both the aluminum alloy upper hangers 25 and the aluminum alloy lower hangers 26 are installed on the same side of the second horizontal keel 23. The structure of the aluminum alloy upper hanger 25 is as follows: Figure 10 As shown, its cross-sectional structure is Z-shaped. The aluminum alloy upper bracket 25 can be divided into a first connecting plate 251, a second connecting plate 252, and a third connecting plate 253 connected in sequence. Fixing holes are provided on both the first connecting plate 251 and the third connecting plate 253. The third connecting plate 253 is fixed to the upper second transverse keel 23 by rivets, allowing the first connecting plate 251 to extend upwards beyond the top surface of the second transverse keel 23. The structure of the aluminum alloy lower bracket 26 is as follows... Figure 11 As shown, the cross-section of the aluminum alloy lower pendant 26 resembles a hook-shaped cane. The aluminum alloy lower pendant 26 can be divided into a straight main connecting part 261 and an arc-shaped connecting part 262 with an arc curvature. Figure 11 With the indicated direction as a reference, the arc-shaped connecting portion 262 bends downward to form an arc-shaped groove 263 with an open lower part. The left end of the arc-shaped connecting portion 262 is a free end, and the right end of the arc-shaped connecting portion 262 is integrated with the top end of the main connecting portion 261. On the connection section between the arc-shaped connecting portion 262 and the main connecting portion 261, a second limiting portion 265 perpendicular to the main connecting portion 261 is formed on the left side, and a first limiting portion 264 perpendicular to the main connecting portion 261 is formed on the right side. The first limiting portion 264 is higher than the second limiting portion 264, and an opening is made in the main connecting portion 261 below the second limiting portion 265. Figure 13 As shown, the main connecting part 261 is fixed to the lower second transverse keel 23 by rivets. At this time, the first limiting part 264 is locked at the top of the second transverse keel 23. In order to facilitate the vertical adjustment of the transverse module unit 2 during installation, threaded holes are also opened on the arc-shaped connecting part 262 and height adjustment bolts 6 are installed.

[0042] The vertical module unit 1 and horizontal module unit 2 described above are used to form a hyperbolic decorative line curtain wall through splicing. The installation structure of the hyperbolic decorative line curtain wall is described below: The installation of the vertical module unit 1 is as follows... Figure 7 and Figure 8As shown, vertical module units 1 are spaced apart horizontally, and glass curtain walls are installed between them. Taking the installation structure of a single vertical module unit 1 as an example, the first vertical keel 14 at both ends of the vertical module unit 1 is fixedly connected to the corresponding aluminum alloy column 3 with screws. Since the first vertical keel 14 has a vertical groove 141, it provides adjustment space for the left and right positioning of the vertical module unit 1. After the positioning adjustment is completed, the first vertical keel 14 is fixed to the aluminum alloy column 3 with screws. The first horizontal keel 13 is fixedly connected to the aluminum alloy beam 4 with screws. Since the first horizontal keel 13 has a horizontal groove 131, it provides adjustment space for the up and down positioning of the vertical module unit 1. After the positioning adjustment is completed, the first horizontal keel 13 is fixed to the aluminum alloy beam 4 with screws.

[0043] Following the above, the installation structure of the horizontal module unit 2 is as follows: Figure 12 and Figure 13 As shown, in addition to the hyperbolic decorative lines formed by vertical module units 1 and horizontal module units 2, the entire curtain wall also features glass curtain walls installed on aluminum alloy columns 3 and aluminum alloy beams 4. The glass curtain walls can be installed using existing technology or by employing other methods. Figure 7 The installation of the glass curtain wall is not considered a technical improvement of this invention and is therefore omitted from the description. The installation of the glass curtain wall involves the curtain wall fixing device 5. In this embodiment, the horizontal module unit 2 is connected to the curtain wall fixing device 5, as shown... Figure 13 As shown, the structure of the curtain wall fixing device 5 includes a main body with a rectangular cross-section and a hollow cavity inside. The main body has openings on its outer sidewalls to allow for... Figure 13 With the indicated direction as a reference, an extension rod extends upward from the upper right corner of the main body, with the bottom end of the extension rod integrated with the main body and the top end of the extension rod forming a spherical structure. In this embodiment, multiple horizontal module units 2 are spliced ​​together vertically. Each horizontal module unit 2 has a curtain wall fixing device 5 at its upper and lower ends. Taking the same curtain wall fixing device as a reference, in two adjacent horizontal module units 2, the aluminum alloy upper hanger 25 on the lower horizontal module unit 2 has its first connecting plate 251 fixed to the main body of the curtain wall fixing device 5 by bolts; the aluminum alloy lower hanger 26 on the upper horizontal module unit 2 has its arc-shaped connecting part 262 hooked onto the spherical structure of the curtain wall fixing device 5. The spherical structure is located in the arc-shaped groove 263, allowing the horizontal module unit 2 to be adjusted 360° around the spherical structure. The second limiting part 265 on the aluminum alloy lower hanger 26 can effectively prevent the spherical structure from falling out of the arc-shaped groove 263. Since the aluminum alloy undermount 26 is equipped with a height adjustment bolt 6, the vertical height of the horizontal module unit 2 can be adjusted by rotating the height adjustment bolt 6.

[0044] The vertical module unit 1 and horizontal module unit 2 designed in this invention can form a hyperbolic decorative line curtain wall through installation. Both the vertical module unit 1 and the horizontal module unit 2 adopt a modular design and are prefabricated in the factory and directly assembled on the construction site, which is convenient and quick. Both the vertical module unit 1 and the horizontal module unit 2 can be positioned and adjusted during assembly, which improves the installation accuracy of the curtain wall.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
