Description

Technical Field

[0001] This utility model relates to the field of curtain wall structure technology, and in particular to a steel frame curtain wall structure. Background Technology

[0002] A curtain wall is a non-load-bearing structure on the exterior of a building, typically made of lightweight materials such as glass, metal, and stone. It is primarily used for decoration and protection of buildings, while also giving them a more modern and aesthetically pleasing appearance. The curtain wall system does not bear the main load of the building structure; it only withstands external forces such as wind and snow loads and transfers them to the building structure. Its design typically focuses on aesthetics, airtightness, thermal insulation, sound insulation, and waterproofing.

[0003] In actual curtain wall construction, existing curtain wall structures often face the following technical problems: Traditional curtain wall structures use a large number of bolts, nuts, and other fasteners for connection, making the installation process cumbersome and complex. Especially before the actual installation, pre-installation is required, which not only expends significant time and manpower on dismantling but also necessitates tightening and loosening all connection points individually. This undoubtedly prolongs installation and dismantling time and reduces installation efficiency. More importantly, the use of numerous fasteners makes the entire dismantling process more complex, increases the difficulty of operation, and makes the maintenance and replacement of the curtain wall structure even more cumbersome. Utility Model Content

[0004] The main purpose of this utility model is to provide a steel frame curtain wall structure that improves installation efficiency and ease of operation, and also enhances seismic performance.

[0005] To achieve the above objectives, this utility model proposes a steel frame curtain wall structure, comprising:

[0006] Several embedded parts are fixedly connected to the exterior wall, and a support frame is fixedly connected to the side of the embedded parts away from the wall, and a receiving frame is fixedly connected to the side of the support frame.

[0007] A plurality of vertical keels and a plurality of horizontal keels, wherein the vertical keels and horizontal keels are detachably and fixedly connected to the supporting frame, and each of the vertical keels is fixedly connected with a limit plug.

[0008] A limiting component is disposed on the receiving frame and is used to fix and limit the connection between each limiting plug and the receiving frame;

[0009] Several buckle plates are fixedly installed along the long side of the vertical keel and the long side of the horizontal keel, respectively.

[0010] In one possible implementation, the limiting component includes a limiting disk and an elastic pad. The limiting disk is rotatably mounted on the receiving frame. Two limiting grooves are provided on the limiting disk. The end of the limiting groove away from the opening gradually approaches the axis of the limiting disk. A locking groove with the same inner diameter is provided on one side of the inner wall of each limiting groove. The locking groove is opened in the direction away from the axis of the limiting disk.

[0011] Each of the aforementioned limiting plugs is fixedly connected to a limiting pin, and the outer diameter of each limiting pin is smaller than the inner diameter of the limiting groove.

[0012] The elastic pads are positioned at both ends of the supporting frame.

[0013] In one possible implementation, stepped grooves are equidistantly provided on the limiting plate along the shape of the limiting groove and the locking groove, and a stepped ring is fixedly connected to the limiting pin.

[0014] In one possible implementation, the outer wall of the stepped ring is provided with a plurality of positioning grooves, and positioning pins are fixedly connected to the limiting plate near the positioning grooves, with the end of the positioning pin facing the positioning groove corresponding to the shape of the positioning groove opening.

[0015] In one possible implementation, the receiving frame has sliding grooves on both sides, and the limiting plug has corner plates fixedly connected to both sides. Each corner plate abuts against the adjacent sliding groove, and the horizontal keel has an alignment groove with the corner plate angle corresponding to the end of the receiving frame.

[0016] In one possible implementation, the shape of the receiving frame is higher on one side of the supporting frame than on the other side, the end of the vertical keel connected to the receiving frame is opened in accordance with the shape of the receiving frame, and the shape of the elastic pad is set in accordance with the shape of the receiving frame.

[0017] In one possible implementation, the supporting frame has a reinforcing groove on the side facing the receiving frame, and the receiving frame has reinforcing ribs that correspond to the shape of the reinforcing groove opening.

[0018] In one possible implementation, a reinforcing frame and a reinforcing plate are provided within the support frame near the location where it connects to the embedded part.

[0019] This utility model's technical solution significantly improves the stability of the entire curtain wall system and enhances its resistance to deformation by utilizing the combined stress of the supporting frame and the load-bearing frame. During installation and dismantling, optimized connection designs (such as limiting plugs, limiting plates, and elastic pads) not only improve installation efficiency and ease of operation but also enhance seismic performance and reduce reliance on traditional connection methods. Furthermore, the rational coordination of these designs makes subsequent maintenance and dismantling work simpler and faster, greatly improving work efficiency and reducing operational difficulty.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] This utility model proposes a steel frame curtain wall structure.

[0032] Example 1

[0033] Reference Figures 1 to 6 It includes a limiting component, several buckle plates 17, several vertical keels 14, several horizontal keels 15 and several embedded parts 11 that are fixedly connected to the exterior wall. The side of the embedded part 11 away from the wall is fixedly connected to the support frame 12, and the side of the support frame 12 is fixedly connected to the receiving frame 13.

[0034] A supporting frame 13 was added to the existing supporting frame 12 to enhance the strength and stability of the curtain wall system. The supporting frame 13 shares the load with the supporting frame 12, effectively increasing the load-bearing thickness of the supporting frame 12 and thus improving the overall curtain wall's resistance to deformation after installation. This design significantly enhances the structural stability of the curtain wall system, reduces potential deformation and swaying, and ensures durability and safety during long-term use. Simultaneously, this improvement facilitates easier disassembly of the vertical and horizontal keels 14 and 15 during subsequent curtain wall removal, improving installation efficiency and reducing labor intensity during dismantling.

[0035] The vertical keel 14 and the horizontal keel 15 are detachably and fixedly connected to the supporting frame 13, and each vertical keel 14 is fixedly connected to each limiting plug 16.

[0036] To further improve the connection accuracy and stability of the vertical keel 14, a limiting plug 16 was designed as a reinforcement at the connection point between the supporting frame 13 and the vertical keel 14. Through the use of the limiting plug 16, the vertical keel 14 can be aligned and connected more accurately and conveniently, avoiding the alignment difficulties and accuracy problems of traditional methods. The design of the limiting plug 16 also enhances the connection strength between the vertical keel 14 and the supporting frame 13, ensuring the stability of the overall structure, especially effectively improving the seismic resistance at the connection point. During the assembly and disassembly of the vertical keel 14, the design of the limiting plug 16 also makes the disassembly operation simpler and more efficient, reducing cumbersome steps in the removal process.

[0037] For the installation of the horizontal keel 15, an internal mounting component design is adopted, allowing the horizontal keel to be easily fitted onto the mounting component. The mounting component is first installed on both sides of the supporting frame 13, thus completing the entire installation process. The horizontal keel 15 is installed on both sides of the supporting frame 13 via the mounting component, ensuring a tight fit between the keel and the supporting frame 13, enhancing its overall strength and stability. This optimized design reduces complex connection processes, making the installation process more convenient and time-saving.

[0038] The limiting component is set on the receiving frame 13 to fix and limit the connection between each limiting plug 16 and the receiving frame 13;

[0039] Furthermore, through optimized design of the limiting components, particularly the combined application of the limiting plate 21, elastic pad 25, and limiting pin 24, the installation of the vertical keel 14 becomes simpler and more efficient. The limiting plate 21 can quickly connect the vertical keel 14 by rotation, greatly reducing reliance on traditional bolt connections. The elastic pad 25 not only ensures the stable connection of the vertical keel 14 but also effectively buffers wall vibrations, enhancing the overall structure's seismic resistance and improving the seismic performance and long-term stability of the curtain wall system.

[0040] The design of the limiting pin 24, in conjunction with the limiting groove 22, allows it to be tightly engaged into the locking groove 23 through elasticity, ensuring connection stability and effectively improving safety and efficiency during installation. This design significantly reduces operational difficulty, simplifies worker procedures, and facilitates subsequent disassembly and maintenance.

[0041] Each buckle plate 17 is fixedly installed along the long side of the vertical keel 14 and the long side of the horizontal keel 15.

[0042] Finally, the design of the snap-on panel 17 is used to seal the gaps after the curtain wall is installed, ensuring the overall consistency of the curtain wall, while limiting the range of motion of the curtain wall, effectively preventing the risk of the curtain wall falling, and increasing the safety of the curtain wall structure.

[0043] In summary, the combined stress of the supporting frame 12 and the receiving frame 13 significantly improves the stability of the entire curtain wall system and enhances its resistance to deformation. During installation and dismantling, optimized connection designs (such as the limiting plug 16, limiting plate 21, and elastic pad 25) not only improve installation efficiency and ease of operation but also enhance seismic performance and reduce reliance on traditional connection methods. Furthermore, the rational coordination of these designs makes subsequent maintenance and dismantling work simpler and faster, greatly improving work efficiency and reducing operational difficulty.

[0044] Reference Figures 2 to 4 The limiting component includes a limiting plate 21 and an elastic pad 25. The limiting plate 21 is rotatably mounted on the receiving frame 13. Two limiting grooves 22 are opened on the limiting plate 21. The end of the limiting groove 22 away from the opening gradually approaches the axis of the limiting plate 21. A locking groove 23 with the same inner diameter is opened on one side of the inner wall of each limiting groove 22. The locking groove 23 is opened in the direction away from the axis of the limiting plate 21.

[0045] Each limiting pin 24 is fixedly connected to each limiting plug 16. The outer diameter of each limiting pin 24 is smaller than the inner diameter of the limiting groove 22, ensuring that the limiting pin 24 can quickly pass through the limiting groove 22 and can fit against the inner wall of the limiting groove 22.

[0046] The elastic pads 25 are positioned at both ends of the supporting frame 13.

[0047] During the installation of the vertical keel 14, the limiting plate 21 in the limiting component allows for easy installation of both sections of the vertical keel 14 simply by rotating the limiting plate 21. The elastic pad 25 ensures a stable connection between the two ends of the vertical keel 14, and its elastic properties effectively buffer vibrations from the wall, thus preventing structural instability caused by vibrations.

[0048] Furthermore, as the limiting groove 22 moves, the limiting pin 24 can be tightly locked into the locking groove 23 when it reaches the innermost position due to the release of elasticity, thus ensuring the installation stability and reliability of the vertical keel 14.

[0049] This design not only simplifies the installation process and reduces reliance on bolts and nuts, thus decreasing the number of connecting parts and reducing installation difficulty for workers, but also improves the overall installation efficiency of the curtain wall due to its simpler and more efficient installation method. Furthermore, this design greatly simplifies the curtain wall dismantling process, facilitating later maintenance or replacement work. Therefore, this solution effectively improves the overall ease of installation, stability, and maintainability of the curtain wall, offering significant advantages.

[0050] Reference Figure 5 The reinforcing frame 122 and the reinforcing plate 123 are provided inside the support frame 12 near the position where they are connected to the embedded part 11.

[0051] Since the support frame 12 is the main load-bearing component, it must be ensured to have sufficient supporting strength. At the connection point between the support frame 12 and the embedded part 11, bolts and nuts are typically used. However, bolts are susceptible to shear forces after connection, which can cause deformation at the connection point between the bolt and the support frame 12, increasing the size of the mating hole and potentially leading to connection instability. Therefore, to enhance connection stability, a reinforcing frame 122 and a reinforcing plate 123 are added. The addition of the reinforcing frame 122 and the reinforcing plate 123 effectively increases the contact area between the support frame 12 and the bolts, thereby dispersing shear forces and improving the deformation resistance at the bolt-support frame 12 connection point. This design significantly improves the overall installation stability, prevents structural failure due to unstable connections, and ensures the long-term reliability and safety of the support frame 12.

[0052] Example 2

[0053] This embodiment improves the connection relationship between the limiting plate 21 and the limiting pin 24 based on embodiment 1;

[0054] Reference Figure 4 and Figure 6 The limiting plate 21 has stepped grooves 26 equidistantly provided along the shape of the limiting groove 22 and the locking groove 23, and the stepped ring 27 is fixedly connected to the limiting pin 24.

[0055] By adding the stepped ring 27, the contact area between the limiting plate 21 and the limiting pin 24 is effectively increased, thus significantly enhancing the connection stability between them. The stepped ring 27 is positioned within the stepped groove 26. This design not only effectively distributes the shear force generated by gravity on the limiting pin 24, but also significantly reduces the shear deformation effect of the limiting pin 24 on the limiting plate 21, especially during the contact with the surface of the frame 13. This ensures the fit strength between components and enhances their individual structural strength, thereby strengthening the overall strength and stability of the curtain wall. Through this improvement, the various components of the curtain wall can better withstand external impacts, ensuring the stability and safety of the curtain wall during long-term use.

[0056] Example 3

[0057] This embodiment improves the connection relationship between the limiting plate 21 and the limiting pin 24 based on embodiment 2;

[0058] Reference Figure 6 Several positioning grooves 28 are formed on the outer wall of the stepped ring 27. The positioning pins 29 are fixedly connected to the positioning plate 21 near the locking groove 23. The end of the positioning pin 29 facing the locking groove 23 is set to correspond to the shape of the groove opening of the positioning groove 28.

[0059] When the limiting plate 21 locks and clamps the limiting pins 24 on both sides, securing the limiting pins 24 in the locking groove 23, to further enhance the stability of the limiting plate 21 on the limiting pins 24, locating pins 29 can be added to both sides of the limiting plate 21. One end of the locating pin 29 faces the locating groove 28 and precisely matches the shape of the groove opening, thereby effectively and accurately limiting the position of the limiting pin 24. Through this design, the locating pin 29 not only provides additional stable support but also ensures that the limiting pin 24 remains fixed during use, preventing positional shift or loosening due to external forces or vibrations, thus improving the reliability and safety of the system. This improvement effectively enhances the connection stability between the limiting plate 21 and the limiting pins 24, ensuring the stability and performance of the mechanical device during long-term use.

[0060] Example 4

[0061] This embodiment improves the connection stability of the overall curtain wall based on embodiment 1;

[0062] Reference Figures 4 to 5 Two slides 131 are provided on both sides of the supporting frame 13, and two corner plates 161 are fixedly connected to both sides of the limiting plug 16. Each corner plate 161 abuts against the adjacent slide 131. The corner plate 161 is provided with a corresponding alignment groove 151 at one end of the horizontal keel 15 near the supporting frame 13.

[0063] To ensure the overall aesthetics of the curtain wall, especially when using glass curtain walls, it is usually necessary to minimize obstruction of the view. Therefore, the traditional practice is to install an additional screw at an angle at the junction of the vertical keel 14 and the horizontal keel 15 to enhance the connection strength. However, while this method can temporarily strengthen the connection, it also has some problems. First, drilling and installing a screw will cause irreversible deformation of the shape of the vertical keel 14 and the horizontal keel 15, affecting the aesthetics of the structure. Second, the addition of the screw increases the difficulty of removal, and because the position and angle of this additional design part are affected by the installation worker's operation, it leads to a reduction in the overall installation effect.

[0064] To overcome these problems, this design introduces corner plate 161. Corner plate 161 provides additional support during the connection of the vertical keels 14 on both sides, thus enhancing the connection strength of the horizontal keels 15 on both sides, while avoiding the deformation and subsequent dismantling complexity caused by traditional drilling and screw methods. By adding corner plate 161, the contradiction between aesthetics and stability is resolved, making the connection between the vertical keels 14 and the horizontal keels 15 more stable, avoiding the influence of human factors, and thus significantly improving the overall installation strength and effect of the curtain wall. This improved solution has the following advantages: 1. Avoids external damage: By using corner plate 161 instead of screws for reinforcement, not only is deformation of the vertical and horizontal keels avoided, but also permanent damage affecting the appearance is prevented. 2. Improves stability: The introduction of corner plate 161 enhances the support strength of the connection points, making the connection between the vertical and horizontal keels more stable and avoiding structural weaknesses caused by drilling. 3. Simplifies the dismantling process: Since additional screws are no longer needed, the dismantling process is simpler, reducing the difficulty of dismantling and the risk of damage. 4. Ensuring Aesthetics: The design of Corner Plate 161 ensures the aesthetics of the connection points without affecting the overall visual effect of the curtain wall, meeting the dual requirements of modern architecture for both aesthetics and functionality. Therefore, using Corner Plate 161 not only improves installation strength and appearance but also ensures structural stability and long-term reliability.

[0065] Example 5

[0066] This embodiment improves upon the shape of the supporting frame 13 based on embodiment 1;

[0067] Reference Figures 2 to 5 The shape of the supporting frame 13 is higher on one side than the other side of the supporting frame 12. The end of the vertical keel 14 connected to the supporting frame 13 is opened in accordance with the shape of the supporting frame 13. The shape of the elastic pad 25 is set in accordance with the shape of the supporting frame 13.

[0068] By carefully improving the shape of the supporting frame 13, especially by designing one side to be higher than the other, the ease with which workers connect the supporting frame 12 and the supporting frame 13 is greatly improved. The higher side of the supporting frame 13 effectively avoids unnecessary obstruction to workers during installation, making the installation process smoother, reducing construction difficulty, and thus improving the installation efficiency of the curtain wall.

[0069] In addition, this shape improvement, while retaining the original flush contact, increases the contact area and improves the stress distribution at the connection points, making the stress distribution of the two frames more uniform and helping to improve the overall stability and reliability of the structure.

[0070] Meanwhile, the shape design of the supporting frame 13 ensures that the weight of the vertical keel 14 is no longer directly concentrated at one location, but is distributed and transmitted towards the wall according to the position of the embedded parts 11. Through this shape improvement, the force is distributed more evenly, thereby reducing the risk of structural deformation or damage that may be caused by force concentration.

[0071] In summary, this optimization of the supporting frame 13 not only improves the compatibility between the components, but also enhances the overall strength and stability of the curtain wall, ensuring the reliability and durability of the curtain wall system in long-term use.

[0072] Example 6

[0073] This embodiment improves upon embodiment 1 by modifying the shape of the support frame 12 and the receiving frame 13 that fit together.

[0074] Reference Figure 5 A reinforcing groove 121 is formed on the side of the support frame 12 facing the receiving frame 13, and a reinforcing rib 132, which corresponds to the shape of the groove 121, is formed on the receiving frame 13.

[0075] By cleverly incorporating reinforcing grooves 121 and reinforcing ribs 132 into the design, the connection between the support frame 12 and the receiving frame 13 becomes tighter and more stable. The design of the reinforcing groove 121 increases the contact area between the support frame 12 and the receiving frame 13, ensuring more sufficient contact at the connection point, thereby improving the overall strength and stability of the connection.

[0076] Meanwhile, the reinforcing groove 121 makes the installation process more convenient. During assembly, workers only need to follow the guide of the reinforcing groove 121 to easily fix the supporting frame 13 in place, reducing the installation difficulty and greatly improving construction efficiency. The support frame 12 and the supporting frame 13 are connected by bolts, which further ensures the reliability of the connection.

[0077] The reinforcing rib 132 strengthens the connection point by increasing the thickness of the joint, thereby enhancing the structure's load-bearing capacity. This thickened design not only improves the compressive strength of the connection point but also effectively disperses external forces, reducing potential localized stress concentrations and preventing loosening or instability caused by external forces. Through these technical means, the integrated connection method not only enhances the stability and safety of the structure but also significantly reduces construction and installation difficulty, improving project efficiency.
