Abstract
Description
A steel support structure for curved glass curtain walls Technical Field
[0001] This utility model belongs to the field of glass curtain wall technology, specifically relating to a steel support structure for curved glass curtain walls. Background Technology
[0002] Glass curtain walls, as a widely used facade form in modern high-rise buildings, are favored by architects due to their transparency, lightness, and strong modern feel.
[0003] Traditional glass curtain wall systems often include canopy structures to prevent rainwater from directly entering the interior and to provide some sun shading. Early versions of these structures were mostly planar in form, with relatively simple supporting structures, typically composed of straight steel components, making them easy to fabricate and install. However, as architectural design has increasingly emphasized aesthetic appeal, traditional planar canopies have become insufficient to meet the demands of complex and ever-changing building exteriors.
[0004] In recent years, an increasing number of buildings have adopted curved canopy designs to enhance their overall dynamism and visual impact. These curved canopies not only improve the building's artistic expression but also contribute to more efficient airflow and lighting effects. However, traditional linear steel support structures are clearly ill-suited to the spatial variations required by curved canopies. Therefore, a new type of steel structure support is needed that can meet structural safety and stability requirements, while also balancing ease of construction and cost-effectiveness, and harmonizing with the overall architectural form. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steel support structure for curved glass curtain walls.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A steel support structure for a curved glass curtain wall includes several steel frame columns fixed to concrete structural columns by embedded parts. The steel frame columns are arranged in three arc-shaped rows: front, middle, and rear. A main frame is fixed to the top of each steel frame column. The main frame has an overall arc shape and a fan-shaped top view. The main frame is welded from several main beams. The front row of steel frame columns is fixed to an upper arch beam by cantilever beams. The upper arch beam is connected to a lower arch beam by several inter-beam support beams. The lower arch beam gradually approaches the upper arch beam from the middle to both ends. The overall shape of the upper arch beam, lower arch beam, and support beams is an irregular curved surface. Embedded steel plates are installed on the concrete structural columns corresponding to the two ends of the lower arch beam, and the two ends of the lower arch beam are fixed to the embedded steel plates.
[0008] Furthermore, the concrete structural columns at both ends of the lower arch beam are aligned with the steel frame columns in the front row.
[0009] Furthermore, both ends of the lower arch beam are located below the ground surface.
[0010] Furthermore, the main frame is provided with several arc-shaped roof beams; curtain wall keels are fixed between the beam support beams, upper arch beams, and lower arch beams.
[0011] Furthermore, two main auxiliary beams are symmetrically arranged in the middle of the main frame, and the main auxiliary beams are located in the middle of the front side of the main frame; the two ends of the main auxiliary beams are respectively fixed to the steel frame columns in the front row and the middle row, and vertical support beams are fixed on the main auxiliary beams.

[0017] Furthermore, one of the beam support beams is welded from multiple square steel bars, and the two square steel bars at the interface are reinforced and connected by side fasteners.
[0018] This utility model is applicable to all-glass curtain wall buildings such as hotels, office buildings, and shopping malls with a shared entrance hall structure. The steel frame columns of this utility model are fixed to the entrance hall's roof slab. The roof beams are fitted with the top glass curtain wall, which covers the entrance hall's roof slab and connects to the curved glass curtain wall on the surface of the twin towers.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0033] This utility model is applicable to all-glass curtain wall buildings such as hotels, office buildings, and shopping malls with a shared entrance hall structure, and is used to connect the glass curtain walls of the two towers on both sides of the entrance hall and to provide a supporting structure for the entrance hall canopy.
[0034] As shown in Figures 1 to 7, a steel support structure for a curved glass curtain wall includes several steel frame columns 2 fixed to concrete structural columns 100 by embedded parts 1. The steel frame columns 2 are arranged in three arc-shaped rows: front, middle, and rear. As shown in Figure 4, specifically, the steel frame columns 2 are fixed to the top of the concrete structural columns 100 that are higher than the lobby ceiling 200. To distinguish them, column heads 11 are used to indicate the concrete structural columns 100 that are higher than the lobby ceiling 200.
[0035] The steel frame column 2 is fixed to the top of a main frame. The main frame has an overall arc shape and a fan shape when viewed from above. The main frame is welded from several main beams 4. The front row of steel frame columns 2 is fixed to an upper arch beam 6 via cantilever beams 10. The upper arch beam 6 is connected to a lower arch beam 7 via several inter-beam support beams 8. The lower arch beam 7 gradually approaches the upper arch beam 6 from the middle to both ends. The upper arch beam 6, lower arch beam 7, and support beams have an overall irregular curved surface shape. Pre-embedded steel plates 17 are installed on the concrete structural columns 100 corresponding to the two ends of the lower arch beam 7. The two ends of the lower arch beam 7 are fixed to the pre-embedded steel plates 17. Several arc-shaped roof beams 5 are provided on the main frame to support the glass curtain wall that connects the twin towers on both sides in an arc shape. Curtain wall keel 9 is fixed between the inter-beam support beams 8, the upper arch beam 6, and the lower arch beam 7 for installing the irregular curved glass canopy.
[0036] Furthermore, the front row of steel frame columns 2 is aligned with the concrete structural columns 100 at the corners of the twin towers. The concrete structural columns 100 at these corners are concrete structural columns 100 with embedded steel plates 17. The embedded steel plates 17 are located on the front side of the concrete structural columns 100. The two ends of the lower arch beam 7 are set as inclined surfaces and can fit with the embedded steel plates 17. The two ends of the lower arch beam 7 are fixed to the embedded steel plates 17 by welding the inclined surfaces.
[0037] The two ends of the lower arch beam 7 can be set above the ground surface, below the ground surface, or flush with the ground surface. Here, the ground surface refers to the hardened ground surface of the entrance hall. Preferably, the two ends of the lower arch beam 7 are located below the ground surface, and the lower end of the lower arch beam 7 is protected and auxiliaryly supported by the hardened concrete layer of the ground surface.
[0038] Further, as shown in Figures 1 to 4, the steel frame columns 2 can be considered as being arranged in 6 columns, with the middle two columns having only one steel frame column 2, and each of the other columns having 3 steel frame columns 2. The main beam 4 includes straight support beams 41 fixed between the steel frame columns 2, several vertical support beams 42 fixed on the straight support beams 41, two middle beams 43 fixed on the vertical support beams 42, and straight edge beams 44 and curved edge beams 45 forming the four sides of the main frame. The straight support beams 41 are fixed to the four columns of steel frame columns 2 on both sides, and each straight support beam 41 steel frame column 2 is fixed by 3 steel frame columns 2, arranged radially. The middle beams 43 have the same shape as the roof beams 5, except that all materials (square steel) are larger and have a stronger load-bearing capacity. The curved edge beams 45 are fixed to the front and rear rows of steel frame columns 2, and the straight edge beams 44 are fixed to the ends of the curved edge beams 45 and the middle beams 43, with the straight edge beams 44 located at the highest and outermost positions of the main frame. The height of the vertical support beam 42 and the shape of the column frame are adjusted according to the design requirements of the glass curtain wall to form a good connection with the glass curtain walls of the buildings on both sides of the lobby.
[0039] Furthermore, as shown in Figures 1 to 4, two main reinforcement beams 15 are symmetrically arranged in the middle of the main frame. The main reinforcement beams 15 are located in the middle of the front side of the main frame. The front end of the main reinforcement beams 15 is fixed to the steel frame columns 2 in the middle two columns of the front row, and the rear end of the main reinforcement beams 15 is fixed to the steel frame columns 2 in the second and fifth columns of the middle row, which are used to strengthen the support of the weak support in the middle of the main frame. Several vertical support beams 42 are fixed on the main reinforcement beams 15. The height of these vertical support beams 42 is adjusted according to the shape of the middle beam 43 or the roof beam 5 to be supported.
[0040] Furthermore, as shown in Figures 1 to 4, the top surface of the vertical support beam 42 is inclined and a support plate 14 is fixed thereon. The support plate 14 is used to support the middle beam 43 / roof beam 5. The size of the support plate 14 is larger than the size of the vertical support beam 42, which reduces the assembly accuracy requirements.
[0041] Furthermore, as shown in Figures 1 to 4, a horizontally extending side column 12 is provided on the straight beam 44. A square plate 13 is fixed to the end of the side column 12. The square plate 13 is used to weld and connect with the pre-embedded connectors in the concrete structural columns 100 of the towers on both sides of the entrance hall, thereby enhancing the stability of the steel support structure of the present invention.
[0042] Furthermore, as shown in Figures 1 to 4, the upper arch beam 6 includes an arc-shaped segment in the middle and straight segments at both ends of the arc-shaped segment. An arch connecting column 16 extending horizontally backward is provided at the straight segment of the upper arch beam 6. A square plate 13 is fixed to the end of the arch connecting column 16. The square plate 13 is used for welding and fixing the pre-embedded connectors in the concrete structural columns 100 at the corners of the twin towers, thereby enhancing the installation stability of the upper arch beam 6.
[0043] Furthermore, as shown in Figures 1 and 6, the column base of the steel frame column 2 is fixed with several column base plates 3. The column base plates 3 are fixed in pairs on the four sides of the steel frame column 2. The bottom of the column base plates 3 is fixed on the embedded parts 1 to enhance the connection.
[0044] Furthermore, as shown in Figures 1 and 7, in this utility model, the canopy design is at least two stories high. Therefore, one of the beam support beams 8 needs to be shaped and welded from multiple square steel bars. The two sides of the square steel bars at the interface are reinforced and connected by side fasteners 18. The side fasteners 18 consist of two spaced first steel plates and a second steel plate fixed to the two sides of the two first steel plates.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
