Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving building curtain walls, and in particular relates to a multi-curvature special-shaped glass curtain wall system. Background Art

[0002] In today's ever-changing era, the role of architecture has far exceeded the simple shelter from the wind and rain. They have integrated into nature, become the coordinator of harmonious coexistence of the environment and the disseminator of aesthetics, and give people an unprecedented aesthetic experience. In this context, the architects' ingenious design of special-shaped buildings has become synonymous with exploring novelty and breaking through tradition, inspiring the public's infinite longing and expectation for the future form of architecture. People eagerly hope that in the future, more innovative buildings will emerge in our daily lives. These buildings are not only beautiful and pleasing to the eye, but also can blend harmoniously with the natural environment.

[0003] Curtain walls, as the "skin" of buildings, are particularly unique in special-shaped buildings. Their flowing lines and smooth curves present stunning artistic effects, especially glass curtain walls, which have become the core element of curtain wall design for special-shaped buildings with their excellent transparency and rich decorative properties. Special-shaped glass curtain walls are often composed of surfaces with complex curvatures such as arcs, spheres, and free-form surfaces, interspersed with planes and single curved surfaces. At present, faced with this kind of special-shaped glass curtain wall with variable curvature, BIM software is generally used for curvature analysis and optimization first, striving to optimize the glass panels of the curtain wall into flat panels and single-curved panels to the maximum extent while ensuring the effect. For example, a Chinese invention patent application with application publication number CN115478641A and application publication date of December 16, 2022 discloses a glass curtain wall system with a mix of vertical surfaces, inclined surfaces and curved surfaces. The glass curtain wall in this glass curtain wall system is only distributed in the plane, and the curved surface part is an aluminum single panel system. Its adjustable connecting plate cannot adapt to the change in the angle between two adjacent aluminum single panels. Once the angle changes slightly, such as when the concave arc disclosed in its document changes to a convex arc, the adjustable connecting plate can only be customized again. A Chinese invention patent application with application publication number CN113089913A and application publication date 2021.07.09 discloses a curved glass curtain wall installation system, which is an open frame or vertical open and horizontal hidden system, and can only adjust the curvature change in one direction of the open frame, and can only be a concave arc. A Chinese utility model patent with authorization announcement number CN202359712U and authorization announcement date 2012.08.01 discloses a curtain wall combination, which can only adjust the curvature change in one direction, and can only be a concave arc. The appearance gap is adjusted by changing the size of the gusset plate. Different angle changes require the matching of multiple gusset plates, which is expensive and time-consuming.

[0004] However, there are still some hyperbolic panels and free-form panels. Then, the construction plan of the glass curtain wall system is determined according to the type of panel. However, due to the wide variety of panels of special-shaped glass curtain walls and their irregular arrangement, multiple glass curtain wall systems are often used in an interlaced manner, which brings many problems to the design and construction.

[0005] In order to overcome the above problems and promote the standardization and unification of the design of special-shaped glass curtain walls, it is urgent to innovate a special-shaped glass curtain wall system that can adapt to various curvature changes, aiming to solve the problems of diverse curvatures and irregular layouts of glass panels, and to achieve simplification and efficiency of curtain wall design and construction.

[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods and in conjunction with the accompanying drawings.

[0031] A multi-curvature special-shaped glass curtain wall system comprises a curtain wall column subsystem 1, a curtain wall crossbeam subsystem 2 and a glass panel subsystem 3. The angles of the opposite ends of two adjacent glass panel subsystems 3 are adjustable on the curtain wall column subsystem 1 and the curtain wall crossbeam subsystem 2, so that the glass curtain wall can smoothly transition between different curvatures of a plane, a convex surface and a concave surface, and can realize high-quality, efficient and smooth installation of special-shaped glass curtain walls with variable curvatures.

[0032] The curtain wall column subsystem 1 includes a column 11 and two Z-shaped pressing blocks 12. The column 11 includes a concave arc edge 111 and cantilevered edges 112 located on both sides of the concave arc edge 111. During construction, the length of the cantilevered edge 112 can be cut twice according to the curvature of the glass curtain wall. One end of the Z-shaped pressing block 12 is set as a convex arc edge 121 adapted to the shape of the concave arc edge 111, and the other end is set as a straight insertion edge 122. The convex arc edge 121 is attached to the concave arc edge 111 and fixedly connected by screws 14. The two insertion edges 122 are respectively connected to the opposite ends of the two adjacent glass panel subsystems 3 on the left and right.

[0033] The curtain wall crossbeam subsystem 2 includes a crossbeam 21, a crossbeam sub-component 25 and two Z-shaped pressing blocks 22. The crossbeam 21 includes a concave arc edge 211 and cantilevered edges 212 located on both sides of the concave arc edge 211. During construction, the length of the cantilevered edge 212 can be cut twice at the construction site according to the curvature change of the glass curtain wall. One end of the Z-shaped pressing block 22 is set as a convex arc edge 221 adapted to the shape of the concave arc edge 211, and the other end is set as a straight insertion edge 222. The convex arc edge 221 is attached to the concave arc edge 211 and is fixedly connected by screws 24. The two insertion edges 222 are respectively connected to the opposite ends of the upper and lower adjacent glass panel subsystems 3.

[0034] Among them, when the length of the cantilever edge 112 and the cantilever edge 212 is cut for the second time, when the joint of the glass plate 31 is a concave arc, the length of the cantilever edge 112 and the cantilever edge 212 becomes longer as the curvature becomes smaller, and when the joint of the glass plate 31 is a convex arc, the length of the cantilever edge 112 and the cantilever edge 212 becomes shorter as the curvature becomes smaller.

[0035] An arc block 26 is provided between the crossbeam sub-component 25 and the upper glass panel subsystem 3, and the arc block 26 is used to transfer the self-weight of the upper glass panel subsystem 3 and rotate with it. Specifically, the upper and lower sides of the arc block 26 are respectively provided with a plane end and a curved surface end, the plane end is fitted with the end surface of the upper glass panel 31, and the curved surface end is in contact with the crossbeam end 251, so that the arc block 26 can transfer the self-weight of the upper glass panel 31 and can also rotate with the upper glass panel 31, thereby ensuring the smooth adjustment and firm installation of the glass panel 31.

[0036] The crossbeam sub-component 25 includes a crossbeam end 251, the middle of which is provided with a heat-insulating broken bridge 2511, and one end of the crossbeam end 251 is provided with an end convex arc edge 2512 adapted to the shape of the concave arc edge 211, and the end convex arc edge 2512 is fitted with the concave arc edge 211 and fixedly connected by screws 3 252. The end convex arc edge 2512 cooperates with the concave arc edge 211, so that the crossbeam end 251 can be firmly fixed on the crossbeam 21, so as to ensure that the buckle cover 271 cooperates with the shaping rubber strip 1 273 to firmly press and fix the glass plate 31.

[0037] The inner cavity of the crossbeam 21 is clamped with an angle code component 28, and the angle code component 28 is fixedly connected to the column 11, so that the crossbeam 21 is fixed on the column 11 to form a curtain wall skeleton. The inner cavity opening side of the crossbeam 21 is clamped with a cover plate 213. After the angle code component 28 is installed, the cover plate 213 is buckled on the crossbeam 21 to cover the angle code component 28, ensuring a simple and beautiful appearance.

[0038] The glass panel subsystem 3 includes a glass plate 31, a weatherproof structural adhesive 32, a glass subframe 33 and a second shaping adhesive strip 34. The glass plate 31 is a flat plate or a curved plate. One side of the glass subframe 33 is fixedly connected to the periphery of the glass plate 31 by the weatherproof structural adhesive 32, and the other side is provided with an inclined mounting groove, in which a second shaping adhesive strip 34 is installed. The inclined mounting groove matches the concave arc edge 111. With the aid of the second shaping adhesive strip 34, the direction of the glass plate 31 can be easily adjusted, and the glass plate 31 can be stably supported. The middle part of the glass subframe 33 is provided with an insertion groove 331 for the corresponding insertion edge 122 or the insertion edge 222 to be inserted, and the ends of the insertion edge 122 and the insertion edge 222 are provided with sealing protrusions that contact the glass subframe 33. In the glass panel subsystem 3 of this structural form, the glass plate 31 is easy to adjust and quickly installed, and the glass plate 31 after adjustment can be firmly fixed.

[0039] During installation, the insertion edge 122 is inserted into the insertion groove 331 of the corresponding glass sub-frame 33, and then the convex arc edge 121 is closely attached to the concave arc edge 111 and slides along the concave arc edge 111 until it adapts to the curvature of the glass panel 31 at that location, so that the left and right adjacent glass panels 31 transition smoothly, and finally the two convex arc edges 121 are fixedly connected to the concave arc edge 111 by screws 14.

[0040] During installation, the second insertion edge 222 is inserted into the corresponding insertion groove 331 of the glass sub-frame 33, and then the second convex arc edge 221 is closely attached to the second concave arc edge 211 and slides along the second concave arc edge 211 until it adapts to the curvature of the glass plate 31 at that location, so that the upper and lower adjacent glass plates 31 transition smoothly, and finally the second convex arc edge 221 is fixedly connected to the second concave arc edge 211 by the second screw 24.

[0041] A sealing strip 13 matching the corresponding glass panel 31 is installed at the end of the cantilever edge 112. The length of the flange end of the sealing strip 13 located on the inner side of the cantilever edge 112 is greater than the length of the flange end located on the outer side of the cantilever edge 112. The sealing strip 13 is used to fill and adapt to the gap between the glass panel 31 and the cantilever edge 112 caused by the change of small curvature (within ±3° of rotation). A sealing strip 23 matching the corresponding glass panel 31 is installed at the end of the cantilever edge 212. The length of the flange end of the sealing strip 23 located on the inner side of the cantilever edge 212 is greater than the length of the flange end located on the outer side of the cantilever edge 212. The sealing strip 23 is used to fill and adapt to the gap between the glass panel 31 and the cantilever edge 212 caused by the change of small curvature (within ±3° of rotation). The structural form in which the inner and outer flange ends of the sealing strip 1 13 and the sealing strip 2 23 have different lengths can make the sealing strip 1 13 and the sealing strip 2 23 more convenient to be connected to the cantilever edge 1 12 and the cantilever edge 2 212, thereby improving the installation efficiency. In addition, the long inner flange end can ensure the firmness of the installation without affecting the appearance, while the short outer flange end can better reflect the appearance while ensuring stable installation.

[0042] The other end of the cross beam end 251 extends into the opposite ends of the upper and lower adjacent glass panels 31 and is fixedly connected with a buckle cover assembly 27, which includes a buckle cover 271, a buckle strip 272, a screw 274 and two shaping rubber strips 273. The two ends of the buckle cover 271 respectively press the two shaping rubber strips 273 on the outer sides of the opposite ends of the upper and lower adjacent glass panels 31. A groove 2711 is provided in the middle of the buckle cover 271. The screw 274 used to fix the buckle cover 271 with the cross beam end 251 is installed in the groove 2711. The buckle strip 272 is buckled at the open end of the groove 2711 to cover the screw 274. The buckle cover assembly 27 of this structural form is easy to install and can achieve firm fixation of the adjusted glass panel 31.

[0043] The Z-shaped pressing block 12 and the Z-shaped pressing block 2 22 have the same structure and size, the sealing strip 13 and the sealing strip 2 23 have the same model, and the screw 1 14, the screw 2 24, the screw 3 252 and the screw 4 274 have the same model, which can not only reduce material processing specifications, but also facilitate on-site material use, reduce construction costs, and improve installation efficiency.

[0044] Technical features not described in the present invention can be implemented by existing technologies and will not be described in detail here. The present invention is not limited to the above specific embodiments, and changes, modifications, additions or substitutions made by ordinary technicians in the field within the essential scope of the present invention should also fall within the protection scope of the present invention.
