[0039] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0040] Reference Figures 1 to 11 As shown, a hyperboloid curtain wall system is provided, including multiple hyperboloid metal panels 1. Adjacent hyperboloid metal panels 1 are connected by arc-shaped corner bracket connection structures 2. A curtain wall column 8 is fixedly connected to the end of the arc-shaped corner bracket connection structure 2 away from the hyperboloid metal panel 1. The two sides of the hyperboloid metal panel 1 are folded inward to form a folded corner 11 in the middle of the hyperboloid metal panel 1. The hyperboloid metal panel 1 includes a left rear end face 12 and a right rear end face 13. The left rear end face 12 and the right rear end face 13 are respectively provided with four keels 3. Adjacent keels 3 are rotatably connected by a first sleeve connection structure 4 to form a quadrilateral structure. The right keel of the left rear end face 12 and the left keel of the right rear end face 13 are rotatably connected by a second sleeve connection structure 5. The left keel of the left rear end face 12 and the right keel of the right rear end face 13 are both equipped with a third sleeve connection structure 6. The two third sleeve connection structures 6 are connected by a crossbeam 7.

[0041] In this embodiment, the hyperboloid metal panel 1 is composed of two irregular quadrilaterals with four non-coplanar hyperboloids (viewed from above, it is a support composed of two arbitrary quadrilaterals, each corner of which can rotate; viewed from the front, it is an arbitrary triangular support, each corner of which can rotate. The quadrilateral support and the triangular support are assembled together to form a support with four non-coplanar corners of the quadrilaterals). This results in various angle splicing of the keel 3 (including aluminum alloy columns and aluminum alloy beams) supporting the irregular quadrilateral panel. To address this, multiple sleeve connection structures are used to solve the problem of keel splicing at different angles. These multiple sleeve connection structures enable keel splicing at any angle, avoiding the need to mill the keel 3 at different angles, greatly reducing processing difficulty and cost, and significantly improving keel splicing efficiency. At the same time, the arc-shaped corner bracket connection structure 2 effectively solves the connection and alignment problems caused by the varying angles of the panels in complex curved curtain walls, ensuring the smoothness of the building's appearance.

[0042] In some embodiments of the present invention, the arc-shaped corner bracket connection structure 2 includes a mounting base 21 connected to the curtain wall column 8. Two arc-shaped sliders 22 are movably disposed on the top of the mounting base 21. The top of the two arc-shaped sliders 22 is provided with a smooth arc surface 221. Arc-shaped corner brackets 23 are movably connected to the top of the two arc-shaped sliders 22. The arc-shaped corner brackets 23 can slide back and forth on the arc surface 221. The bottom sides of the mounting base 21 are provided with first elongated holes 211. The first elongated holes 211 are connected to the curtain wall column by bolts so that the mounting base 21 can be adjusted up and down. The bottom of the arc-shaped sliders 22 is provided with second elongated holes 222. The second elongated holes 222 are connected to the top of the mounting base 21 by bolts so that the arc-shaped sliders 22 can be adjusted left and right. The inner surface of the arc-shaped corner brackets 23 is a serrated surface. The inner surface of the arc-shaped corner brackets 23 is connected to the serrated pad 24 by bolts.

[0043] In this embodiment, by setting up mutually cooperating arc-shaped corner brackets 23 and arc-shaped sliders 22, the normal angle of the hyperboloid metal plate 1 is infinitely adjustable through their arc surface contact. Local positional fine-tuning in the up / down and left / right directions is achieved through the first elongated hole 211 of the mounting base 21 and the second elongated hole 222 of the arc-shaped slider 22, forming a multi-directional linkage adjustment system. Finally, a secure locking is achieved after adjustment through the engagement of the serrated pad 24 with the inner serrated surface of the arc-shaped corner bracket 23. Thus, a one-stop solution is provided for the connection, adjustment, and fixing of multi-angle panels in complex metal roofing systems, significantly improving installation accuracy, efficiency, and structural reliability.

[0044] Preferably, the mounting base 21 has a U-shaped structure, and the hyperboloid metal plate 1 is a metal plate with a folded hyperboloid shape. The middle part of the hyperboloid metal plate 1 protrudes outward to form a folded angle 11, and the angle of the folded angle 11 is in the range of 90 to 180 degrees.

[0045] In some embodiments of the present invention, the top and bottom sides of the mounting base 21 are provided with first serrations 212, and the bottom of the arc-shaped slider 22 is provided with second serrations 223. The first serrations 212 and second serrations 223 on the top of the mounting base 21 cooperate with each other so that the arc-shaped slider 22 can move back and forth on the top of the mounting base 21. The bottom of the arc-shaped slider 22 is provided with a second elongated hole 222, which can realize local adjustment in the left and right directions. The arc surface 221 is a smooth surface, which cooperates with the second arc surface 231 of the arc-shaped corner bracket 23 to realize sliding adjustment.

[0046] In some embodiments of the present invention, a groove 213 is provided at the top center of the mounting base 21, and the second elongated hole 222 is fixedly connected to the groove 213 by a fixing bolt. The head diameter of the fixing bolt is larger than the top opening diameter of the groove 213, so that the fixing bolt is stuck in the groove 213.

[0047] On the main keel of the metal curtain wall system, a mounting base 21 is arranged every 300mm to connect the curtain wall columns of the metal curtain wall. The top and bottom sides of the mounting base 21 are designed with a serrated shape. The bottom sides are provided with first elongated holes 211 to meet the local vertical adjustment. The top center is provided with a sliding groove 213 to insert and lock the head of M6 stainless steel bolts. The bolts are connected and fixed by the arc-shaped slider 22 on the mounting base 21.

[0048] In some embodiments of the present invention, the arc-shaped corner bracket 23 is provided with a second arc surface 231 that cooperates with the arc surface 221 at one end near the arc-shaped slider 22, so that the arc-shaped corner bracket 23 can slide back and forth along the arc surface 221, thereby realizing the adjustment of the normal deviation of the hyperboloid metal plate 1 and satisfying the installation and adjustment between hyperboloid metal plates 1 at any angle. The arc-shaped corner bracket 23 is provided with a third elongated hole 232 at one end near the arc-shaped slider 22. The third elongated hole 232 is fixedly connected to the top of the arc-shaped slider 22 by bolts. After the hyperboloid metal plate 1 is adjusted by the arc-shaped corner bracket 23 and the arc-shaped slider 22, the arc-shaped corner bracket 23 and the arc-shaped slider 22 are fixedly connected by the serrated shim 24 and bolts.

[0049] Preferably, the end of the arc-shaped corner bracket 23 away from the arc-shaped slider 22 is connected to another curtain wall column via a locking bolt 25. The other curtain wall column is connected to a hyperboloid metal plate 1. A serrated washer 24 is fitted on the locking bolt 25. The locking bolt 25 passes through the serrated washer 24 and the arc-shaped corner bracket 23 in sequence and is fixedly connected to the other curtain wall column. The serrated washer 24 and the inner serrated surface of the arc-shaped corner bracket 23 engage to achieve a firm lock after adjustment.

[0050] The curtain wall columns, mounting base 21, arc-shaped slider 22, arc-shaped corner bracket 23, and serrated pad 24 are all made of aluminum alloy.

[0051] The arc-shaped corner bracket connection structure 2 consists of a mounting base 1 with a first serration 12 and a sliding groove 13, an arc-shaped slider 2 with a second elongated hole 22, and an arc-shaped corner bracket 3 with a smooth bottom surface and a serrated top surface. Through the engagement of the serrations of the mounting base 1 and the arc-shaped slider 2 with the elongated hole, precise micro-adjustments of the connection point in the up-down and left-right directions are achieved. More importantly, the arc-shaped corner bracket 3 can slide along the arc of the top surface of the slider, thus flexibly adapting to and ultimately locking adjacent hyperboloid metal panels (i.e., curtain wall panels) with different normal angles (90-180 degrees). This effectively solves the connection and alignment problems caused by the varying angles of curtain wall panels in complex curved curtain walls, ensuring a smooth and flat building appearance.

[0061] An installation method for a hyperboloid curtain wall system, comprising the aforementioned hyperboloid curtain wall system, and including the following steps:

[0062] S1. Connect the second connecting surface 92 and the first connecting surface 91 with the third sleeve connecting structure 6 and the first sleeve connecting structure 4 to form an integral four-point non-coplanar support.

[0063] S2. By using the corner assembly cavity 95 of the skeleton 9, the skeleton 9 is assembled at the corners to improve its assembly accuracy;

[0064] S3. Adapt the hyperboloid metal plate 1 to the four non-coplanar supports to form a folded hyperboloid panel. Reinforce the connecting end 94 and insert it into the insertion slot 10 of the folded hyperboloid panel. Secure the connection points of the folded hyperboloid panel with screws.

[0066] S4. Two adjacent hyperboloid metal plates 1 are connected to the arc-shaped corner bracket connection structure 2 by bolts, and the other end of the arc-shaped corner bracket connection structure 2 is fixed to the curtain wall column 8.

[0067] Through the above steps, the original flat panel is fitted into a hyperbolic panel. The three-dimensional hyperbolic panel is then flattened and unfolded into a two-dimensional flat panel in the software for cutting and processing. On-site, the flat panel is forcibly installed and fixed onto non-coplanar supports, and the elastic deformation of the material naturally fits and generates the required hyperbolic shape. This method transforms the complex spatial curved surface processing into standard flat panel processing and on-site modular assembly, fundamentally reducing the processing difficulty and cost of the panel while ensuring the realization of the final curved surface effect.

[0068] The above is a further detailed description of the present invention and should not be considered as a limitation on the specific implementation of the present invention. For those skilled in the art, simple deductions or substitutions without departing from the concept of the present invention are all within the protection scope of the present invention.
