Description

Technical Field

[0001] This invention relates to a modular assembly system for curtain walls of irregular tower crowns in ultra-high-rise buildings, belonging to the field of building curtain wall technology. Background Technology

[0002] Super high-rise building tower crowns often adopt irregular designs such as irregular curved surfaces and multi-angle turns. Existing modular curtain wall systems are mostly designed for regular facades and lack universal adaptability assembly measures for irregular tower crowns. This leads to problems such as uneven splicing gaps or insufficient structural strength, eccentric pre-set hole positions, and assembly difficulties. In addition, traditional curtain wall unit panels require customized processing, which is costly and difficult to standardize. They have poor adaptability to irregular shapes, and modular technology has difficulty overcoming its limitations. Summary of the Invention

[0003] To address the aforementioned technical problems, the objective of this invention is to propose a modular assembly system for irregular tower crown curtain walls in ultra-high-rise buildings.

[0004] The technical solution of this invention is implemented as follows: a modular assembly system for an irregular tower crown curtain wall of a super high-rise building, comprising a steel frame, steel pipe columns, glass panels, and connecting components; the steel frame and steel pipe columns are staggered front to back, and two sets of connecting components are provided, each set being located at one end of the glass panel to install the two ends of the glass panel onto the steel frame and steel pipe columns respectively; each connecting component includes a fiberglass channel and a channel base, the channel base being connected and fixed to the front end of the steel frame or steel pipe column, and the end of the glass panel being embedded and fixed in the fiberglass channel; the fiberglass channel is rotatably mounted on the channel base to adjust the angle of the glass panel, and after the angle of the glass panel is adjusted, the fiberglass channel and the channel base are fixed and locked.

[0005] Preferably, the outer side of the fiberglass trough is integrally formed with a rotating rod, and the steel trough base is provided with a groove for the rotating rod to rotate. The fiberglass trough and the steel trough base are rotatably engaged through the rotating rod and the groove.

[0006] Preferably, the rotating rod and the groove are fixed and locked together by welding.

[0007] Preferably, the width of the fiberglass channel is greater than the thickness of the glass panel, a first rigid pad is provided at the bottom of the fiberglass channel, and a second rigid pad is provided on both sides of the glass panel embedded in the fiberglass channel.

[0008] Preferably, the steel frame is made of multiple galvanized steel pipes welded together, and the front end of the steel pipe column is welded and fixed with an angle steel connector, and the steel channel base located at one end of the glass panel is connected and fixed to the angle steel connector.

[0009] Preferably, the outer periphery of the steel frame is covered and fixed with a first decorative aluminum plate, the first and last ends of the first decorative aluminum plate are respectively fitted into the two sides of the fiberglass channel through a bending structure, and sealant is applied at the connection; the outer periphery of the steel pipe column is covered and fixed with a second decorative aluminum plate, the first and last ends of the second decorative aluminum plate are respectively fitted into the two sides of another fiberglass channel through a bending structure, and sealant is applied at the connection.

[0010] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0011] 1. This invention adapts to changes in facade depth by staggering the front and rear of the steel frame and steel pipe columns, and with the rotation angle adjustment structure of the fiberglass channel and steel channel base, it can flexibly adapt to irregular tower crown shapes with irregular curved surfaces and multi-angle turns. It eliminates the need for customized irregular glass and special support components, and ensures uniform splicing gaps, thus solving the problem of insufficient adaptability of traditional modular systems to irregular tower crowns.

[0012] 2. The fiberglass channel has a pre-set assembly tolerance, and the glass angle can be flexibly adjusted on site. Combined with the fine-tuning capability of the angle steel connector, it can effectively absorb component processing errors and on-site installation deviations, avoid assembly difficulties caused by pre-set hole misalignment, greatly improve on-site construction efficiency, and reduce installation difficulty and construction costs.

[0013] 3. Core components such as fiberglass channels, steel channel bases, and decorative aluminum panels can all be prefabricated in a standardized manner. Only on-site assembly and angle adjustment are required, eliminating the need for extensive customization. This breaks through the limitations of traditional irregular curtain wall customization, which is characterized by high costs and difficulty in standardizing production. It effectively controls project costs while ensuring styling adaptability. Attached Figure Description

[0020] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0023] As attached Figure 1-3 As shown, the modular assembly system for an irregular tower crown curtain wall of a super high-rise building according to the present invention includes a steel frame 1, steel pipe columns 2, glass panels 3, and connecting components.

[0024] Among them, the steel frame 1 and the steel pipe column 2 are staggered in front and behind along the depth direction of the tower crown facade. There are two sets of connecting components, which are respectively set at both ends of the glass panel 3, so that the two ends of the glass panel 3 are respectively installed on the steel frame 1 and the steel pipe column 2.

[0025] As attached Figure 2-4 As shown, specifically, the connecting component includes a fiberglass channel 41 and a steel channel base 42. The steel channel base 42 is connected and fixed to the front end of the steel frame 1 or the steel pipe column 2 by welding. The end of the glass panel 3 is embedded and fixed in the fiberglass channel 41. The fiberglass channel 41 forms a wrapping limit on the end of the glass panel 3, preventing the edge of the glass panel 3 from being directly exposed and damaged by impact, while providing uniform support force for the glass panel 3.

[0026] The fiberglass trough 41 is rotatably mounted on the steel trough base 42 to adjust the angle of the glass panel 3 to accommodate the multi-angle turning shape of the irregular tower crown. In this embodiment, a rotating rod 411 is integrally formed on the outer side of the fiberglass trough 41, and a groove 421 for the rotating rod 411 to rotate is provided on the steel trough base 42. The fiberglass trough 41 and the steel trough base 42 are rotatably engaged by the rotating rod 411 and the groove 421. The integrally formed rotating rod 411 structure can ensure the structural strength of the rotating part and avoid the problems of breakage and loosening of the spliced ​​rotating structure, thereby improving the long-term reliability of the system. The assembly of the groove 421 and the rotating rod 411 is simple. On-site, the rotating rod 411 only needs to be inserted into the groove 421 to complete the pre-installation, without complicated alignment procedures, resulting in high construction efficiency.

[0027] After the angle of the glass panel 3 is adjusted, the fiberglass channel 41 and the steel channel base 42 are fixed and locked. In this embodiment, the rotating rod 411 and the groove 421 are fixed and locked by welding. The joint between the rotating rod 411 and the groove 421 is fully welded to make them a whole. The welding method has high connection strength and no risk of loosening or slippage. It can withstand the strong wind load and temperature deformation stress of the super high-rise tower crown, thereby ensuring the long-term structural stability of the curtain wall system. At the same time, it can be directly locked after on-site adjustment, without the need for prefabricated components with fixed angles. It can flexibly adapt to the tower crown facade with different turning angles, solving the problem of the eccentricity of the pre-set hole positions of traditional curtain walls and the inability to adapt to irregular shapes.

[0028] As attached Figure 2-3 As shown, the width of the fiberglass groove 41 is greater than the thickness of the glass panel 3. A first hard pad 412 is provided at the bottom of the fiberglass groove 41, and a second hard pad 413 is provided on both sides of the glass panel 3 embedded in the fiberglass groove 41.

[0029] After the glass panel 3 is embedded in the groove, its end abuts against the surface of the first rigid pad 412, and the two side panels are clamped and fixed to the groove wall by the second rigid pad 413. By setting the first rigid pad 412 and the second rigid pad 413, direct rigid contact between the glass panel 3 and the metal inner wall of the fiberglass groove 41 is avoided, effectively buffering the vibration load caused by wind vibration of the super high-rise building, dispersing the stress concentration at the edge of the glass, and preventing the glass edges from chipping and breaking under load. At the same time, the design of the groove width of the fiberglass groove 41 being greater than the thickness of the glass panel 3 provides sufficient assembly tolerance, which can absorb the processing error of the glass panel 3 and the on-site installation deviation, reduce the difficulty of alignment and assembly, and improve construction efficiency.

[0030] As attached Figure 1 As shown, in this embodiment, the steel frame 1 is made of multiple galvanized steel pipes welded together to improve the overall structural rigidity and wind load resistance, thereby adapting to the strong wind conditions at the crown of the super high-rise tower. Angle steel connectors 21 are welded and fixed to the front end of the steel pipe column 2, and the steel channel base 42 located at one end of the glass panel 3 is connected and fixed to the angle steel connectors 21.

[0031] Furthermore, a first decorative aluminum plate 11 is fixedly wrapped around the outer periphery of the steel frame 1. The first decorative aluminum plate 11 is bent into shape along the outer contour of the steel frame 1. The first and last ends of the first decorative aluminum plate 11 are respectively fitted into the two sides of the fiberglass channel 41 through a bending structure, and sealant 5 is applied at the connection. A second decorative aluminum plate 22 is fixedly wrapped around the outer periphery of the steel pipe column 2. The second decorative aluminum plate 22 is also bent into shape along the outer contour of the steel pipe column 2. The first and last ends of the second decorative aluminum plate 22 are respectively fitted into the two sides of the other fiberglass channel 41 through a bending structure, and sealant 5 is applied at the connection.

[0032] The steel frame 1 and steel pipe columns 2 are covered with decorative aluminum panels, which can conceal the internal support structure and improve the overall appearance and aesthetics of the tower crown curtain wall, meeting the facade design requirements of super high-rise buildings. The connection method of end bending and fitting eliminates the need to open additional connection holes on the fiberglass channel 41, avoiding the weakening of the channel structure strength by opening holes. At the same time, it is easy to assemble and can be directly clamped and fixed on site. The sealant 5 at the connection can seal the assembly gaps, achieve a waterproof and dustproof sealing effect, and improve the weather resistance of the system.

[0033] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
