[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model discloses a large-span curtain wall system, relating to the design, processing, and installation of component-type glass curtain walls for building curtain walls, such as... Figure 1 As shown, the large-span curtain wall system includes multiple hangers 2 and multiple horizontal keels 1. The horizontal keels 1 include multiple first horizontal keels 11 and multiple second horizontal keels 12. The multiple first horizontal keels 11 and multiple second horizontal keels 12 are fixed to the building structure. The multiple hangers 2 are fixed to the building structure. The multiple first horizontal keels 11 are fixed to the building structure. A second horizontal keel 12 is fixedly connected between two first horizontal keels 11. The hangers 2 are inserted and fixed to the first horizontal keels 11.

[0030] The large-span curtain wall system disclosed in this utility model has its upper end fixed to the building structure and used for load-bearing. It can effectively transfer the weight of the curtain wall system to the main building structure, ensuring the stability of the curtain wall under its own weight. The horizontal keel 1 is fixed to the building structure and fixedly connected to the hanger 2. It can resist wind and wind loads, preventing the curtain wall from undergoing excessive deformation, displacement, or even damage under wind force, thereby enhancing the structural stability of the entire curtain wall system. The system is subjected to forces in both horizontal and vertical directions, which can maximize the utilization rate of component materials and give full play to the performance of the materials themselves. The load is clear and the force transmission path is clear, which can greatly reduce the cross-section of the keel and free up interior space.

[0031] The fixing method between the hanger 2 and the transverse keel 1 is as follows: Figure 2 and Figure 3 As shown, the rear end of the hanger 2 passes through and extends out of the horizontal keel 1. A first fixing member 21 is provided at the end of the extended portion. The first fixing member 21 abuts against and fixes the horizontal keel 1 to fix the horizontal keel 1 to the hanger 2. The first fixing member 21 is provided at the end of the extended portion of the hanger 2 and abuts against and fixes the horizontal keel 1. This can effectively prevent the horizontal keel 1 from sliding or displacing relative to the hanger 2 at the connection point, thereby enhancing the reliability of the connection between the two and improving the stability of the entire curtain wall system when facing external forces such as wind load and self-weight, thus improving the safety of the curtain wall structure.

[0032] Understandably, the upper horizontal keel 1 includes a first horizontal keel 11 and a second horizontal keel 12. In other words, the hanger can pass through the first horizontal keel 11 and be threaded to the first horizontal keel 11, or it can pass through the second horizontal keel 12 and be threaded to the second horizontal keel 12. Similarly, the hanger 2 can also pass through the insert 3 and be threaded to the insert 3. This is the fastening method of the hanger 2 and the star component.

[0033] Furthermore, the first fixing member 21 includes a fixing nut, and the end of the extended portion of the hanger rod 2 is provided with a thread. The fixing nut abuts against the transverse keel 1 through the threaded engagement to fix the transverse keel 1 and the hanger rod 2. The engagement between the fixing nut and the thread at the end of the hanger rod 2 provides greater friction and clamping force to prevent relative sliding or displacement between the transverse keel 1 and the hanger rod 2 at the connection point. It can be understood that the hanger rod 2 can be fixed to the first transverse keel 11, the second transverse keel 12 and the insert 3 by the nut.

[0034] like Figure 3As shown, the horizontal keel 1 includes a first horizontal keel 11 and a second horizontal keel 12. The first horizontal keel 11 is fixedly connected to the hanger 2, and the second horizontal keel 12 is disposed between the two first horizontal keels 11 and fixedly connected to the first horizontal keel 11. Construction workers can more easily fix the first horizontal keel 11 to the hanger 2 and then install the second horizontal keel 12 between the two first horizontal keels 11, which simplifies the construction process and improves construction efficiency.

[0035] The connection method between the second horizontal keel 12 and the first horizontal keel 11 is as follows: Figure 3 As shown, the second horizontal keel 12 is connected to the first horizontal keel 11 with a core 3. The front end of the core 3 is inserted into the inner cavity of the second horizontal keel 12, and a cavity is formed at the rear end of the front end of the core 3. The second horizontal keel 12 is inserted into the cavity. A second fixing member 31 is provided on the outer side of the core 3. The second horizontal keel 12, the first horizontal keel 11, and the core 3 are fixedly connected by the second fixing member 31. The front end of the core 3 is inserted into the inner cavity of the second horizontal keel 12, and the second horizontal keel 12 is inserted into the cavity at the rear end of the core 3. This insertion structure can increase the contact area between the two, so that the second horizontal keel 12 and the first horizontal keel 11 form a whole, jointly bearing the load and dispersing the stress. The presence of the core 3 also plays a certain supporting and reinforcing role, further enhancing the structural stability of the horizontal keel 1. The insertion connection method is relatively simple and effectively improves construction efficiency and shortens the construction cycle. Preferably, the core 3 is made of aluminum alloy.

[0036] To reduce the weight of the keel and facilitate construction and installation, the second horizontal keel 12 is made of lightweight metal. While ensuring structural strength, the lightweight metal second horizontal keel 12 effectively reduces the weight of the middle horizontal keel 1, lowers the load-bearing capacity requirements of the building structure, facilitates handling and installation by construction workers, and improves on-site construction efficiency. At the same time, the lightweight metal material has good processing performance and can be manufactured into various shapes and sizes according to different design requirements.

[0037] Preferably, the first horizontal keel 11 is made of steel, and the second horizontal keel 12 is made of aluminum. Steel has high strength, good toughness and resistance to deformation, which can provide reliable load-bearing capacity and structural stability for the curtain wall system. In particular, it can effectively resist deformation and damage when facing external forces such as wind loads and earthquakes. Aluminum has the advantages of light weight, relatively low cost and good corrosion resistance, which can reduce the weight of the horizontal keel 1, facilitate construction and installation, and reduce material costs and later maintenance costs.

[0038] To improve the load-bearing capacity of the hangers 2 and the horizontal components, one first horizontal keel 11 can have two hangers 2 passing through it, while one second horizontal keel 12 has four hangers 2 passing through it. Understandably, one first horizontal keel 11 can also have four hangers 2 passing through it, and one second horizontal keel 12 can have six hangers 2 passing through it. The design can be carried out according to the specific load-bearing requirements of the curtain wall system.

[0039] Furthermore, the second fastener 31 includes a bolt and a pressure block. The bolt is located on one side of the second horizontal keel 12. The screw of the insert 3 passes through the second horizontal keel 12 and cooperates with the nut of the insert 3 to fix the second horizontal keel 12 and the insert 3. The pressure block is pressed against the outside of the first horizontal keel 11. The pressure block is provided with a screw. The screw presses against the first horizontal keel 11 to fix the first horizontal keel 11 and the insert 3. According to different building structure forms, span requirements and load distribution, the size, shape and connection method of the keel can be flexibly adjusted to adapt to the requirements of large-span curtain wall systems and ensure the reliability and stability of the connection.

[0040] Furthermore, the first horizontal keel 11 includes a T-shaped steel and a hanging piece. The T-shaped steel is fixedly connected to the hanging piece and the T-shaped steel is connected to the insert 3 to provide the main wind resistance. The hanging piece is fixedly connected to the T-shaped steel by bolts, which can block wind and rain and increase the aesthetics.

[0041] In another embodiment of this utility model, a decorative strip is provided on the outside of the hanging rod 2, and the hanging rod 2 is hidden in the vertical decorative strip, making the curtain wall facade look more concise and neat.

[0042] like Figure 3 As shown, in another embodiment of this utility model, there are at least two hangers 2, and two adjacent hangers 2 are fixedly connected by sleeves 22. Multiple hangers 2 share the load and are connected by sleeves 22 to form a stable support system, which can effectively distribute and transfer the load and improve the self-weight bearing capacity of the curtain wall system.

[0043] In another embodiment of this utility model, the building structure is provided with embedded parts, and the horizontal keel 1 is welded and fixed to the embedded parts so that the horizontal keel 1 is fixed to the building structure. The embedded parts are pre-embedded in the structure during the building construction stage, which can provide a firm anchor point. Welding and fixing the horizontal keel 1 and the embedded parts can simplify the construction process and improve construction efficiency.

[0044] The large-span curtain wall system disclosed in this utility model has the following advantages:

[0045] 1. With the increasing variety of span structures, the curtain wall system disclosed in this utility model can save indoor space to the maximum extent. Its load-bearing form, which uses horizontal keel 1 to resist wind and hangers 2 to bear the load, can well match the requirements of using glass curtain walls to maintain large-span structures.

[0046] 2. Both the hanger 2 and the curtain wall materials are processed in the factory, which reduces on-site material processing, speeds up on-site installation, and the large span of the keel reduces the amount of on-site connection work, greatly improving on-site construction efficiency;

[0047] 3. Outdoor effect: The large horizontal keel 1 not only makes the exterior look simple and elegant, but also provides a certain sunshade effect. The hanging rod 2 is hidden in the vertical decorative strip, so the hanging rod 2 is not visible from the inside or outside, which fully demonstrates the transparency of the glass curtain wall.

[0048] Installation method

[0049] First, the first horizontal keel 11 of steel material is connected to the embedded part through the connector. Then, the first horizontal keel 11 of steel material is connected to the second horizontal keel 12 of aluminum material through the aluminum alloy insert 3. Next, the hanger 2 is installed. After the hanger 2 is installed, the small aluminum alloy base is installed. Then, the glass is installed on the aluminum alloy base. The glass is sealed with sealant around it to make it waterproof. Finally, the decorative strip is installed on the outside of the hanger 2.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
