Description

Technical Field

[0001] This utility model relates to the field of curtain wall system technology, and in particular to an open curtain wall connection system. Background Technology

[0002] In current open-panel curtain wall connection systems, the installation of curtain wall panels generally adopts the traditional "one panel, two beams" structure: that is, the top of a single curtain wall panel needs to be connected to a horizontal beam, and the bottom needs to be connected to another horizontal beam. This results in two independent components between adjacent curtain wall panels, with the bottom horizontal beam of the upper panel and the top horizontal beam of the lower panel. This design leads to a large number of horizontal beams, which not only increases material costs, transportation and installation workload, but also makes the overall curtain wall structure complex with numerous nodes, reducing construction efficiency and making it difficult to meet the development needs of lightweight and efficient building curtain walls.

[0026] See Figures 1 to 8 As shown, this utility model provides a specific embodiment of an open panel curtain wall connection system, including: curtain wall panels 1, horizontal beams 2, a first connecting component 3, and a second connecting component 4; a plurality of curtain wall panels 1 are arranged in a rectangular array on a vertical plane, and the horizontal beam 2 is located between two adjacent curtain wall panels 1; the curtain wall panels 1 located below the horizontal beam 2 are connected to the lower part of the horizontal beam 2 through the first connecting component 3; the curtain wall panels 1 located above the horizontal beam 2 are connected to the upper part of the horizontal beam 2 through the second connecting component 4. Specifically, this embodiment achieves a standardized layout of the curtain wall decorative surface by arranging several curtain wall panels 1 in a rectangular array on a vertical plane. Simultaneously, a horizontal beam 2 is placed between two adjacent curtain wall panels 1, allowing a single horizontal beam 2 to simultaneously serve as the top support for the lower curtain wall panel 1 and the bottom support for the upper curtain wall panel 1. The horizontal beam 2 is then connected to the upper and lower curtain wall panels 1 via a first connecting component 3 and a second connecting component 4, breaking away from the traditional design that requires two independent horizontal beams 2 between the upper and lower panels. This structural integration simplifies the components, reducing the number of horizontal beams 2 by half compared to the traditional design, significantly lowering material costs and installation workload. Furthermore, the independent upper and lower connecting components ensure that the installation and disassembly of the panels do not interfere with each other, facilitating later maintenance and replacement, while also simplifying the overall curtain wall structure and improving construction efficiency.

[0027] It is understood that the material of the curtain wall panel 1 in this embodiment can be a variety of materials such as stone, metal, glass, ceramic and composite materials, and can be set as needed.

[0028] See Figure 4 As shown, in a specific embodiment, the first connecting component 3 includes a bracket 31, a hanger 32, and a back bolt 33. The bracket 31 is installed on the crossbeam 2; one end of the hanger 32 is attached to the bracket 31, and the other end is connected to the curtain wall panel 1 through the back bolt 33.

[0029] Specifically, this embodiment achieves a reliable connection between the curtain wall panel 1 and the horizontal beam 2 through the coordinated action of the bracket 31, the hanger 32, and the back bolt 33. The bracket 31 is fixed to the horizontal beam 2 as a connecting medium, providing stable installation support for the hanger 32; the hanger 32 is connected to the bracket 31 by a hook-on method, which facilitates quick installation and initial positioning; the back bolt 33 is inserted into the interior of the curtain wall panel 1 for fixation, firmly combining the hanger 32 and the curtain wall panel 1. This combination design takes into account both the convenience of installation and the stability of the connection through mechanical locking, effectively transferring various loads on the curtain wall panel 1.

[0030] See Figures 4 to 5 As shown, in a specific embodiment, the mounting bracket 31 includes an adjusting plate 311 and a toothed pad 312; the toothed pad 312, the adjusting plate 311 and the crossbeam 2 are connected in sequence by vertical bolts 313; the adjusting plate 311 is provided with a Z-direction elongated hole 3111, the vertical bolt 313 passes through the Z-direction elongated hole 3111, and both the adjusting plate 311 and the toothed pad 312 are provided with adjusting sawtooth structures 3112, and the two adjusting sawtooth structures 3112 mesh with each other.

[0031] Specifically, this embodiment achieves flexible adjustment and stable fixation of the bracket 31 in the Z-direction (i.e., the direction perpendicular to the surface of the building structure) through the cooperative design of the adjusting plate 311, toothed pad 312, and vertical bolt 313. The Z-direction elongated hole 3111 on the adjusting plate 311 provides movement space for the vertical bolt 313, allowing the adjusting plate 311 to move freely relative to the crossbeam 2 in the Z-direction to compensate for positional errors during the installation of the crossbeam 2. The core function of the adjusting sawtooth structure 3112 between the adjusting plate 311 and the toothed pad 312 is to form a mechanical lock through the interlocking of the teeth after the adjusting plate 311 is adjusted to the appropriate position in the Z-direction. Combined with the tightening force of the vertical bolt 313, the adjusting plate 311 is stably fixed in this position, preventing the adjusting plate 311 from shifting after being subjected to force. The vertical bolt 313, by applying axial pressure, tightly fits the toothed pad 312, the adjusting plate 311, and the crossbeam 2, ensuring the continuous and reliable locking effect of the sawtooth structure.

[0032] See Figures 4 to 5 As shown, in one specific embodiment, the hanger 31 further includes a support plate 314, which is formed by extending upward from the outer side of the adjusting plate 311, and the hanger 32 is hung on the support plate 314.

[0033] Specifically, in this embodiment, a support plate 314 is formed by extending upward from the outer side of the adjusting plate 311, providing a dedicated hanging support surface for the hanger 32. The support plate 314 and the adjusting plate 311 adopt an integrated molding design, avoiding stress concentration and connection gap problems that may occur with split connections. It can directly and continuously transfer the load transmitted by the hanger 32 to the crossbeam 2 through the adjusting plate 311, constructing a complete force path. At the same time, the upwardly extending support plate 314 structure makes the hanging position higher than the plane of the adjusting plate 311, reserving sufficient operation and installation space for the connection of the hanger 32 with the back bolt 33 and the curtain wall panel 1. Moreover, the vertically set support plate 314 can better bear the Y-direction load transmitted by the hanger 32, improving the load-bearing capacity of the hanging structure.

[0034] Furthermore, an adhesive strip 36 is provided between the support plate 314 and the hanger 32. On the one hand, it can fill the assembly gap between the two, avoid direct metal contact to prevent rigid friction or collision, reduce component wear and reduce vibration transmission; on the other hand, it can block external dust and rainwater from seeping into the curtain wall through the connection gap, protect the connection components from corrosion, and enhance the sealing of the connection parts, taking into account both structural durability and curtain wall protection performance.

[0035] In one specific embodiment, the first connecting component 3 further includes an adjusting bolt 34 and a horizontal limiting screw 35. The upper end of the adjusting bolt 34 is connected to the hanger 32, and the lower end abuts against the support plate 314. The support plate 314 is provided with a plurality of connecting holes (not shown in the figure), and the plurality of connecting holes are arranged sequentially along the X direction. The upper end of the horizontal limiting screw 35 is connected to the hanger 32, and the lower end is detachably connected to any connecting hole.

[0036] Specifically, in this embodiment, the Y-axis (i.e., the direction perpendicular to the ground) fine adjustment of the hanger 32 is achieved through the height adjustment bolt 34, and the X-axis (i.e., the length direction of the crossbeam 2) positioning of the hanger 32 is achieved through the horizontal limit screw 35. The height adjustment bolt 34 utilizes the principle of threaded transmission, changing its axial extension length by rotating the bolt, thereby pushing or pulling the hanger 32 relative to the support plate 314 to move up and down in the Y-axis, achieving millimeter-level high-precision height adjustment; the horizontal limit screw 35, through multiple connecting holes arranged along the X-axis on the support plate 314, connects to the hanger 32 by selecting different connecting holes, realizing the adjustment and fixation of the hanger 32 in the X-axis position. The two work together to meet the fine adjustment requirements during installation and ensure the structural stability after adjustment.

[0037] More specifically, the hanger 32 includes a hanging part 321 and a connecting part 322. The hanging part 321 is Π-shaped and hangs on the support plate 314 from above. The connecting part 322 fits against the inner side of the curtain wall panel 1 and is connected to the curtain wall panel 1 by a back bolt 33. The hanging part 321 adopts a Π-shaped structure with an opening facing downwards, which can be inserted into and hung on the support plate 314 from above, achieving rapid pre-positioning while stably bearing vertical loads. Its outline can limit horizontal displacement. The connecting part 322 fits against the inner side of the curtain wall panel 1 and is mechanically anchored by the back bolt 33, which penetrates into the panel and transfers the panel load to the hanging part 321. The integrated structure makes the force path clear, takes into account both installation efficiency and connection strength, and ensures the stable fixation of the curtain wall panel 1.

[0038] Furthermore, the hanger 32 also includes a transition section 323; the upper end of the transition section 323 is inclined inward and connected to the lower end of the hanger 321; the lower end of the transition section 323 is inclined outward and connected to the upper end of the connecting section 322. This design creates a bi-directional inclined transition structure. This design avoids stress concentration at the right-angle connection between the hanger 321 and the connecting section 322, resulting in a smoother load transfer. Furthermore, the inclined angle precisely adapts to the spatial relationship between the hanger 321 and the support plate 314, and between the connecting section 322 and the curtain wall panel 1, optimizing the installation and operation space and enhancing the overall stability and adaptability of the hanger 32 structure.

[0039] In one specific embodiment, the structure of the second connecting component 4 is basically the same as that of the first connecting component 3. The difference is that the second connecting component 4 does not need to be equipped with the height adjustment bolt 34 and the horizontal limit screw 35, and the transition part 323 in the second connecting component 4 is inclined inward at the lower end and connected to the upper end of the hook part 321, and inclined outward at the upper end and connected to the lower end of the connecting part 322.

[0040] Specifically, since the first connecting component 3 is connected to the upper end of the curtain wall panel 1, and the second connecting component 4 is connected to the lower end of the curtain wall panel 1, the installation accuracy of the second connecting component 4 can be indirectly calibrated through the first connecting component 3. Therefore, the height adjustment bolt 34 and the horizontal limit screw 35 can be omitted, thereby simplifying the structure and reducing costs. The transition part 323 is designed with a reverse tilt, with its lower end connected inward to the upper end of the hanging part 321 and its upper end connected outward to the lower end of the connecting part 322. This precisely adapts to the installation space above the horizontal beam 2, coordinates the relative positions of the hanging part 321 and the horizontal beam 2, and the connecting part 322 and the curtain wall panel 1, ensuring a smooth load transfer path and balancing structural stability and installation space adaptability.

[0041] See Figure 1 , Figure 2 and Figure 6As shown, in a specific embodiment, the crossbeam 2 is provided with a first flange 21 and a second flange 22. Both the first flange 21 and the second flange 22 are horizontally arranged, and the first flange 21 is located below the second flange 22. The first connecting component 3 is connected to the first flange 21, and the second connecting component 4 is connected to the second flange 22.

[0042] Specifically, the first flange 21 and the second flange 22 of the horizontal beam 2 are horizontally layered, forming independent upper and lower connection reference surfaces. The lower first flange 21 is adapted for the installation of the first connecting component 3, and the upper second flange 22 corresponds to the connection of the second connecting component 4. The layered layout clearly defines the connection space between the upper and lower curtain wall panels 1, avoiding component interference. The horizontal flange structure provides a stable support surface for the connecting components, ensuring that the load is evenly transferred to the horizontal beam 2, while simplifying installation positioning and improving the orderliness and load-bearing reliability of the curtain wall connection structure.

[0043] See Figure 1 , Figure 2 and Figures 6 to 8 As shown, in one specific embodiment, the end of the beam 2 is connected to a column 5, the inner side of the column 5 is connected to the main body of the building (not shown in the figure), and the curtain wall panel 1 is located on the outer side of the column 5.

[0044] Specifically, the design principle of this embodiment is based on the concept of a frame-type support system. Columns 5 serve as Y-axis load-bearing components, and beams 2 serve as X-axis load-bearing components, connected to form a crisscrossing curtain wall support frame. The inner side of column 5 is directly connected to the main building structure, transferring the overall load borne by the curtain wall to the main building structure, while the outer side provides a Y-axis reference for the installation of the curtain wall panel 1. The end of beam 2 is connected to column 5, allowing the load of curtain wall panel 1 borne by beam 2 to be transferred to column 5, and then to the main building structure. Curtain wall panel 1 is located outside column 5 and connected to beam 2 via connecting components, forming a stable structure supported by both columns 5 and beam 2. This design utilizes the synergistic load-bearing performance of columns 5 and beam 2 to improve the overall wind pressure resistance, earthquake resistance, and other mechanical properties of the curtain wall.

[0045] In one specific embodiment, the crossbeam 2 has a groove 23 inside, and a connecting clip 6 is snapped into the groove 23. The connecting clip 6 is connected to the crossbeam 2 and the column 5 by a bolt assembly 7.

[0046] Specifically, in this embodiment, a groove 23 is provided inside the crossbeam 2. The geometric fit between the groove 23 and the connecting clip 6 enables rapid pre-positioning of both. Then, the connecting clip 6 is rigidly connected to the crossbeam 2 and the column 5 respectively by the bolt assembly 7, thus constructing a stable force transmission structure. The groove 23 inside the crossbeam 2 provides installation space and a limiting base for the connecting clip 6, which can limit the displacement of the connecting clip 6 in the direction perpendicular to the length of the groove 23, ensuring the accurate relative position of the connecting clip 6 and the crossbeam 2. The bolt assembly 7, through axial tightening force, tightly connects the connecting clip 6 to the crossbeam 2 and the connecting clip 6 to the column 5, so that the load borne by the crossbeam 2 can be efficiently transferred to the column 5 through the connecting clip 6, avoiding loss or offset during the load transfer process.

[0047] Furthermore, the crossbeam 2 includes a web 24, a first flange 21, and a second flange 22. Both the first flange 21 and the second flange 22 are connected to the web 24, and a groove 23 is formed between the web 24, the first flange 21, and the second flange 22. The crossbeam 2 connects the horizontally arranged first and second flanges 22 through the web 24, and the three together form the groove 23, eliminating the need for additional groove structure processing and simplifying the manufacturing process. The groove 23 utilizes the structural space of the crossbeam 2 itself to provide an installation cavity for the connecting clip 6. This not only restricts the displacement of the connecting clip 6 through the flanges and the web 24, but also allows the connecting clip 6 to be hidden inside the crossbeam 2, without occupying external space. At the same time, it ensures the overall stress balance of the crossbeam 2, taking into account both installation convenience and structural stability.

[0048] In one specific embodiment, the bolt assembly 7 includes an X-direction bolt 71 and a Y-direction bolt 72. The X-direction bolt 71 is connected to the connecting clip 6 and the column 5, and the Y-direction bolt 72 is connected to the connecting clip 6 and the crossbeam 2.

[0049] Specifically, in this embodiment, the bolt assembly 7 is divided into X-direction bolts 71 and Y-direction bolts 72, which secure the connecting clip 6 to the column 5 and the connecting clip 6 to the beam 2 in different directions. X-direction bolts 71 primarily bear the horizontal load transfer along the X direction, ensuring the relative fixation of the connecting clip 6 and the column 5 in the horizontal direction and preventing the beam 2 from shifting in the X direction under horizontal forces such as wind loads. Y-direction bolts 72 focus on the vertical load transfer along the Y direction, achieving vertical fastening between the connecting clip 6 and the beam 2, ensuring that the beam 2 does not loosen in the Y direction when bearing vertical loads such as the self-weight of the curtain wall panel 1. The two bolts have clear divisions of labor, jointly constructing a multi-dimensional fastening system and improving the stability of the connection structure.

[0050] In one specific embodiment, the connecting clip 6 extends outward to the column 5 with a connecting plate 61, and the connecting plate 61 is connected to the column 5 by a first Z-axis screw 62.

[0051] Specifically, in this embodiment, a connecting plate 61 is extended onto the connecting clip 6, and the connecting plate 61 is connected to the column 5 using a first Z-direction screw 62, forming an auxiliary fixing structure between the connecting clip 6 and the column 5. The extended design of the connecting plate 61 increases the contact area between the connecting clip 6 and the column 5, making the force more dispersed; the first Z-direction screw 62 is tightened along the Z-direction, which can supplement and restrict the slight displacement of the connecting clip 6 in the Z-direction, and at the same time, it forms a three-dimensional fixing system with the X-direction bolt 71 and the Y-direction bolt 72, further improving the reliability of the connection and preventing local shaking of the connecting clip 6.

[0052] In one specific embodiment, a protective panel 8 is provided between the main building and the curtain wall panel 1. The edge of the protective panel 8 is connected to the column 5 and the beam 2 by sealant. The inner side of the beam 2 is provided with a vertical flange 25, which is connected to the protective panel 8 by a second Z-direction screw 9.

[0053] Specifically, in this embodiment, a protective panel 8 is installed between the building structure and the curtain wall panel 1 to form a functional protective layer on the inner side of the curtain wall. The vertical flange 25 on the inner side of the beam 2 serves as the mounting carrier for the protective panel 8, and the two are secured together using a second Z-direction screw 9. The protective panel 8 primarily functions as waterproofing, heat insulation, and sound insulation. The vertical flange 25 provides a stable mounting base for the protective panel 8, avoiding the complex construction problems caused by directly setting installation points on the building structure. The second Z-direction screw 9 connects along the Z-direction, ensuring a tight fixation between the protective panel 8 and the beam 2, preventing the protective panel 8 from falling off due to wind pressure or vibration during use.

[0054] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
