Description

Technical Field

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

[0002] A building curtain wall is a non-load-bearing exterior wall enclosure for a building, typically consisting of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum alloy beams and columns, steel structure, glass ribs, etc.).

[0003] The beams and columns of a building's curtain wall play a crucial role in the overall curtain wall project. They not only undertake the core function of mechanical transmission, ensuring the stability and safety of the curtain wall structure, but also have an undeniable aesthetic and decorative effect, directly affecting the overall stability and visual presentation of the building's appearance.

[0004] However, existing beams and columns are widely fixed using aluminum angle brackets or welding. Aluminum angle brackets result in insufficient mechanical stiffness, while welding leads to insufficient elasticity and inability to adapt to temperature changes. Furthermore, existing beams are typically connected at both ends by welding, restricting the free ends. While this ensures sufficient stiffness and stability, the beam's insufficient elasticity under temperature changes or external impacts makes it prone to brittle fracture, mechanical fatigue, or safety accidents over long-term use. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a curtain wall system, comprising:

The reinforcing core is located in the first cavity and is disposed corresponding to the column. One end of the connector is located in the second cavity, and the other end of the connector extends out of the second cavity and into the first cavity, connecting to the reinforcing core to connect the beam and the column.

[0008] The beam edge structure includes a first connecting plate, a second connecting plate connected to the first connecting plate, and a supporting longitudinal beam arranged along a second direction.

The first positioning member and the positioning hole are in clearance fit, and the second positioning member and the second positioning hole are in clearance fit.

[0009] In some embodiments, the connector includes a first fastening bolt and a first fastening nut located in the first cavity. One end of the first fastening bolt is located in the second cavity and connected to the column, and the other end of the first fastening bolt passes through the first cavity and is threaded to the first fastening nut.

[0010] In some embodiments, the reinforcing core has a first threaded hole, the side surface of the first fastening nut has an external thread, and the first fastening nut is screwed into the first threaded hole; the reinforcing core has a third first cavity, the first fastening nut includes a limiting segment located in the third first cavity and a threaded segment connected to the limiting segment and having the external thread, the threaded segment is screwed into the first threaded hole, and the outer diameter of the limiting segment is larger than the outer diameter of the threaded segment.

[0011] In some embodiments, the side surface of the crossbeam is provided with a first adjustment hole that communicates with the first cavity, the reinforcing core is provided with a second threaded hole corresponding to the position of the first adjustment hole, and the crossbeam column structure further includes a second fastening bolt, the second fastening bolt passes through the first adjustment hole and is screwed into the second threaded hole; the first adjustment hole is an oblong hole, and the length direction of the first adjustment hole is arranged along a first direction.

[0012] In some embodiments, the first positioning hole is an oblong hole, and the length direction of the first positioning hole is arranged along the second direction; the second positioning hole is an oblong hole, and the length direction of the second positioning hole is arranged along the third direction, and the first direction, the second direction, and the third direction are orthogonal to each other.

[0013] In some embodiments, the crossbeam has a first fixing hole at the position corresponding to the first positioning hole, and the side structure of the crossbeam also includes a first positioning nut. The outer surface of the first positioning member has an external thread adapted to the first positioning nut, and the first positioning member passes through the first fixing hole and is screwed with the first positioning nut.

[0014] In some embodiments, the supporting longitudinal beam has a second fixing hole at the position corresponding to the second positioning hole, and the side structure of the crossbeam also includes a second positioning nut located inside the supporting longitudinal beam. The outer surface of the second positioning member has an external thread adapted to the second positioning nut, and the second positioning member passes through the second fixing hole and is screwed with the second positioning nut.

[0015] In some embodiments, the curtain wall system further includes a strength-equal connection structure, which includes fasteners and reinforcing plates. The reinforcing plates are disposed in the first cavity and connected to one end of the crossbeams. The reinforcing plates have fastening holes. Two crossbeams are arranged, with one end of the two crossbeams abutting each other, and the two reinforcing plates are arranged opposite each other. The fasteners include fixing bolts and fastening nuts. One end of the fixing bolt passes through the two fastening holes, and the fastening nut is screwed onto the other end of the fixing bolt.

[0018] The beneficial effects of this application are as follows: By setting connectors and reinforcing cores, the horizontal beam and the vertical column are stably connected. The reinforcing core is set in the first cavity of the horizontal beam and corresponds to the position of the vertical column, which can improve the rigidity of the horizontal beam and vertical column structure. One end of the connector is fixed to the second cavity of the vertical column, and the other end passes through the first cavity and connects to the reinforcing core. This allows for a certain degree of relative deformation between the vertical column and the horizontal beam, preventing them from being completely welded together. This allows the vertical column and the horizontal beam to adapt to temperature changes, enhancing the rigidity and elasticity of the connection between the horizontal beam and the vertical column, thereby effectively improving the overall structure's load-bearing capacity and resistance to deformation. The clearance fit allows for slight displacement between the horizontal beam and the supporting longitudinal beam at the connection point, thereby improving the elasticity of the horizontal beam's edge structure, mitigating the problems of thermal expansion and contraction caused by temperature changes, or stress concentration caused by external impacts (such as wind loads), ultimately improving the elasticity and rigidity of the curtain wall system.

[0036] Please see Figures 1 to 3 This application provides a curtain wall system, which includes a beam-column structure and a beam-edge structure.

[0037] Please see Figures 2 to 4 The beam-column structure includes: a connector 30, a reinforcing core 40, a beam 10 arranged along a first direction, and a column 20 arranged along a second direction. The first direction and the second direction are orthogonal. In this embodiment, the first direction is arranged horizontally, and the second direction is arranged vertically. The reinforcing core 40, the beam 10, and the column 20 can be made of metal, such as aluminum alloy. Aluminum alloy has a high strength-to-weight ratio, is easy to process, and has good corrosion resistance.

[0038] Please see Figures 4 to 6The crossbeam 10 has a first cavity 11, and the column 20 has a second cavity 21. One end of the column 20 abuts against the upper surface of the crossbeam 10 along a first direction. The reinforcing core 40 is located in the first cavity 11 and is positioned corresponding to the column 20. One end of the connector 30 is located in the second cavity 21. Both ends of the column 20 are sealed, and clearance holes are provided at the positions of the crossbeam 10 and the column 20 corresponding to the reinforcing core 40, so that the other end of the connector 30 can pass through the second cavity 21 and into the first cavity 11 to connect with the reinforcing core 40, ultimately achieving the connection between the crossbeam 10 and the column 20. It is understood that multiple connectors 30 can be arranged at intervals. In this embodiment, two connectors 30 are arranged at intervals. In other embodiments, three or more connectors 30 can be provided. Multiple connectors 30 can improve the stability of the connection between the column 20 and the crossbeam 10.

[0039] Please see Figures 7 to 10 The crossbeam edge structure includes: a first connecting plate 71, a second connecting plate 72 connecting the first connecting plate 71, and a supporting longitudinal beam 70 arranged along a second direction. It can be understood that the surface of the first connecting plate 71 is arranged vertically, and the surface of the second connecting plate 72 is arranged horizontally. The first connecting plate 71 and the second connecting plate 72 are connected in an L-shape in space. The materials of the first connecting plate 71, the second connecting plate 72, and the supporting longitudinal beam 70 can all be metals, such as aluminum alloy. Aluminum alloy has a high strength-to-weight ratio, is easy to process, and has good corrosion resistance.

[0040] Please see Figures 7 to 10The first connecting plate 71 and the second connecting plate 72 are respectively arranged opposite the crossbeam 10 and the supporting longitudinal beam 70. The first connecting plate 71 has a first positioning hole 711, and the second connecting plate 72 has a second positioning hole. The side structure of the crossbeam also includes a first positioning member 81 and a second positioning member 82. The first positioning member 81 passes through the first positioning hole 711 and is connected to the crossbeam 10. The second positioning member 82 passes through the second positioning hole 721 and is connected to the supporting longitudinal beam 70. The first positioning member 81 and the positioning hole are in clearance fit, and the second positioning member 82 and the second positioning hole 721 are in clearance fit. It can be understood that the first connecting plate 71 is set opposite to one end face of the crossbeam 10, and the first positioning member 81 passes through the first positioning hole 711 in the horizontal direction and is connected to the crossbeam 10. The second connecting plate 72 is set opposite to the supporting longitudinal beam 70, and the second positioning member 82 passes through the second positioning hole 721 in the vertical direction and is connected to the supporting longitudinal beam 70. It is also understandable that the clearance fit between the first positioning member 81 and the first positioning hole 711, and the clearance fit between the second positioning member 82 and the second positioning hole 721, allows the crossbeam 10 to have a certain amount of movement relative to the supporting longitudinal beam 70, so as to adapt to thermal expansion and contraction due to temperature changes or accidental impacts from external forces.

[0041] Please see Figures 1 to 3 The curtain wall system provided in this application embodiment, by setting connector 30 and reinforcing core 40, firmly connects the horizontal beam 10 and the column 20. The reinforcing core 40 is set in the first cavity 11 of the horizontal beam 10 and corresponds to the position of the column 20, which can improve the rigidity of the horizontal beam and column structure. One end of the connector 30 is fixed to the second cavity 21 of the column 20, and the other end passes through the first cavity 11 and connects to the reinforcing core 40. The column 20 and the horizontal beam 10 can undergo a certain degree of relative deformation, avoiding complete welding between the column 20 and the horizontal beam 10. This allows the column 20 and the horizontal beam 10 to adapt to temperature changes, enhancing the rigidity and elasticity at the connection between the horizontal beam 10 and the column 20, thereby effectively improving the load-bearing capacity and deformation resistance of the overall structure. The ability of the horizontal beam 10 and the supporting longitudinal beam 70 to make small displacements at the connection through clearance fit improves the elasticity of the horizontal beam edge structure, alleviates the problem of thermal expansion and contraction caused by temperature changes, or the problem of stress concentration caused by external impact (such as wind load), and ultimately improves the elasticity and rigidity of the curtain wall system.

[0042] Understandably, two longitudinal support beams 70 are arranged at intervals, and each end of the crossbeam 10 is connected to one of the two longitudinal support beams 70. Furthermore, multiple crossbeams 10 are arranged at intervals along the vertical direction, which gives the connection between the crossbeam 10 and the longitudinal support beams 70 greater elasticity and stability. The arrangement of two longitudinal support beams 70 can distribute the load at both ends of the crossbeam 10, thereby improving the overall load-bearing capacity and deformation resistance of the structure.

[0043] Please see Figures 2 to 4 In some embodiments, the connector 30 includes a first fastening bolt 31 and a first fastening nut 32 located in the first cavity 11. One end of the first fastening bolt 31 is located in the second cavity 21 and connected to the column 20, and the other end of the first fastening bolt 31 passes through the first cavity 11 and is threadedly connected to the first fastening nut 32.

[0044] Please see Figures 2 to 4 Optionally, the use of the first fastening bolt 31 and the first fastening nut 32 not only achieves a tight connection between the crossbeam 10 and the column 20, but also facilitates installation and disassembly. At the same time, the threaded connection can provide additional preload, further enhancing the tensile and shear resistance of the connection and improving the overall stability of the structure. Due to the threaded engagement of the first fastening bolt 31 and the first fastening nut 32, they can deform accordingly when the temperature changes, improving the elasticity of the connection between the column 20 and the crossbeam 10 to adapt to different temperature changes.

[0045] Please see Figures 2 to 4 In some embodiments, the reinforcing core 40 has a first threaded hole 44, and the side surface of the first fastening nut 32 has an external thread, and the first fastening nut 32 is screwed into the first threaded hole 44.

[0046] It is understandable that the first fastening nut 32 has a hollow structure with internal threads. The first fastening bolt 31 is threadedly connected to the first fastening nut 32. The threaded connection between the reinforcing core 40 and the first fastening nut 32 enhances the fixing strength between the first fastening bolt 31 and the reinforcing core 40, making it less prone to loosening or displacement under stress. At the same time, the setting of the first threaded hole 44 makes full use of the structural characteristics of the reinforcing core 40, further improving the rigidity and torsional performance at the connection between the beam 10 and the column 20.

[0047] Please see Figures 2 to 4 In some embodiments, the reinforcing core 40 has a third first cavity 41, and the first fastening nut 32 includes a limiting section 322 located in the third first cavity 41 and a threaded section 321 connected to the limiting section 322 and having the external thread. The threaded section 321 is screwed into the first threaded hole 44, and the outer diameter of the limiting section 322 is larger than the outer diameter of the threaded section 321.

[0048] Optionally, the third first cavity 41 provides a space for the limiting section 322, allowing the first fastening nut 32 to be more securely embedded in the reinforcing core 40. The larger outer diameter of the limiting section 322 increases the contact area with the reinforcing core 40, thereby improving the stability of the connection. At the same time, the limiting section 322 will not slip out of the third first cavity 41 along the first direction. The screw lock between the threaded section 321 and the first threaded hole 44 ensures the rigidity and torsional resistance of the connection between the column 20 and the beam 10.

[0049] Please see Figures 2 to 4 In some embodiments, the side surface of the crossbeam 10 is provided with a first adjustment hole 43 that communicates with the first cavity 11, the reinforcing core 40 is provided with a second threaded hole 46 corresponding to the position of the first adjustment hole 43, and the crossbeam column structure also includes a second fastening bolt 45, which passes through the first adjustment hole 43 and is screwed into the second threaded hole 46.

[0050] Optionally, the engagement of the first adjusting hole 43 and the second fastening bolt 45 allows for fine-tuning of the position of the reinforcing core 40 during installation, enhancing the flexibility and precision of the installation. At the same time, the screwing of the second fastening bolt 45 further strengthens the connection between the reinforcing core 40 and the crossbeam 10, improving the stability and deformation resistance of the overall structure.

[0051] Please see Figures 2 to 4 It is understood that the two opposite surfaces of the crossbeam 10 are provided with first adjustment holes 43, and multiple first adjustment holes 43 can be provided at intervals on the same side surface. Each first adjustment hole 43 is provided with a second fastening bolt 45.

[0052] Understandably, two columns 20 can be arranged on the crossbeam 10, one column 20 connecting to the upper surface of the crossbeam 10 and the other column 20 connecting to the lower surface of the crossbeam 10. Decorative panels are provided on both sides of the crossbeam 10 to cover the second fastening bolt 45.

[0053] Please see Figures 2 to 4 In some embodiments, the reinforcing core 40 further includes a reinforcing rod 42, and the second threaded hole 46 is formed in the reinforcing rod 42. The length direction of the reinforcing rod 42 is arranged along a third direction, and the first direction, the second direction, and the third direction are all orthogonal to each other. The first direction is denoted as X, the second direction as Z, and the third direction as Y.

[0054] Please see Figures 2 to 4Optionally, the reinforcing rod 42 has a hollow structure, and the second threaded hole 46 extends along the length of the reinforcing rod 42. The reinforcing rod 42 can enhance the tensile and compressive strength of the reinforcing core 40 in the third direction, so that the connection between the beam 10 and the column 20 maintains sufficient rigidity and elasticity under multidimensional stress. At the same time, the threaded connection between the second fastening bolt 45 and the reinforcing rod 42 ensures the reliability of mechanical transmission.

[0055] It is understandable that two reinforcing rods 42 are arranged at intervals on the upper surface of the third first cavity 41, and two reinforcing rods 42 are also arranged at intervals on the lower surface of the third first cavity 41, in order to improve the structural strength of the reinforcing core 40.

[0056] Optionally, the crossbeam 10, the column 20, and the reinforcing core 40 have rectangular cross-sections, and the reinforcing core 40 can improve the structural strength and stiffness at the connection between the crossbeam 10 and the column 20.

[0057] Please see Figures 2 to 4 In some embodiments, the first adjustment hole 43 is an oblong hole, and the length direction of the first adjustment hole 43 is arranged along the first direction.

[0058] Optionally, the first adjustment hole 43, which is waist-shaped, not only allows the position of the reinforcing core 40 within the crossbeam 10 to be flexibly adjusted according to actual needs, but also allows the second fastening bolt 45 to be finely adjusted along the first direction when the temperature changes, thereby improving the elasticity of the connection between the column 20 and the crossbeam 10, optimizing the stress distribution between the crossbeam 10 and the column 20, and enhancing the adaptability and ease of installation of the structure.

[0059] Please see Figures 5 to 6 In some embodiments, the beam-column structure further includes a base 50, a first connecting seat 51 connecting the beam 10, and a second connecting seat 52 connecting the base 50. The base 50 and the column 20 are located on opposite sides of the beam 10, and the first connecting seat 51 is connected to the second connecting seat 52.

[0060] Please see Figures 5 to 6 Optionally, the base 50 is connected to the lower surface of the beam 10, and the column 20 is connected to the upper surface of the beam 10. The base 50 can be connected to the building's civil engineering section 101 via the bracket 102, thereby providing support to the base 50 through the civil engineering section 101, and providing additional support points for the beam 10 through the base 50. The connection between the first connecting seat 51 and the second connecting seat 52 enhances the stability between the beam 10 and the base 50, thereby improving the overturning resistance and overall stiffness of the entire structure.

[0061] Please see Figures 5 to 6In some embodiments, the first connecting seat 51 has a first groove 511, the second connecting seat 52 has a second groove 521, the first connecting seat 51 has a second adjusting hole 512 communicating with the groove, and the second connecting seat 52 also has a through hole communicating with the second groove 521. The crossbeam column structure also includes a third fastening bolt 53 and a second fastening nut 54. One end of the third fastening bolt 53 passes through the second adjusting hole 512 and the through hole, and the second fastening nut 54 is screwed onto the other end of the third fastening bolt 53. The second adjusting hole 512 is an oblong hole, and the length direction of the second adjusting hole 512 is arranged along the second direction.

[0062] Please see Figures 5 to 6 Optionally, the first groove 511 and the second groove 521 are connected, and the first groove 511 is partially located inside the second groove 521. That is, through the cooperation of the first groove 511 and the second groove 521, the first connecting seat 51 is partially located inside the second groove 521. The second adjustment hole 512, which is an oblong hole, allows the crossbeam 10 to be finely adjusted along the second direction, improving the elasticity of the entire structure, thus adapting to temperature changes, and also enhancing the flexibility of installation.

[0063] It is understandable that the cross-sectional shape of the first adjusting hole 43 and the second adjusting hole 512 can be either racetrack-shaped or elliptical, so that the second fastening bolt 45 and the third fastening bolt 53 have a certain amount of room to move and adapt to thermal expansion and contraction under temperature changes.

[0064] In some embodiments, the beam-column structure can give the curtain wall system sufficient rigidity and elasticity, thereby improving the stability and safety of the entire curtain wall system, while taking into account the ease of installation and aesthetics, and meeting the high-performance requirements of modern buildings for curtain wall systems.

[0065] Please see Figures 7 to 10 In some embodiments, the first positioning hole 711 is an oblong hole, and the length direction of the first positioning hole 711 is arranged along the second direction.

[0066] Optionally, the length direction of the first positioning hole 711 refers to the direction determined by the long inner diameter of the first positioning hole 711. The cross-sectional shape of the first positioning hole 711 can be racetrack-shaped or elliptical. When the cross-sectional shape of the first positioning hole 711 is elliptical, the major semi-axis of the ellipse is arranged along the second direction, so that the first positioning hole 711 provides the first positioning member 81 with an adjustment range along the second direction, so that the first positioning member 81 can flexibly adjust its position when connecting the crossbeam 10. This not only optimizes the alignment accuracy between the crossbeam 10 and the first connecting plate 71 and reduces installation errors, but also enables the crossbeam 10 to withstand thermal expansion and contraction caused by temperature changes, thus improving the elasticity of the crossbeam edge structure.

[0067] Please see Figures 7 to 10 In some embodiments, the second positioning hole 721 is an oblong hole, and the length direction of the second positioning hole 721 is arranged along a third direction, wherein the first direction, the second direction, and the third direction are orthogonal to each other. It can be understood that the first direction can be represented as X, the second direction as Z, and the third direction as Y.

[0068] Optionally, the length direction of the second positioning hole 721 refers to the direction determined by the long inner diameter of the second positioning hole 721. The cross-sectional shape of the second positioning hole 721 can be racetrack-shaped or elliptical. When the cross-sectional shape of the second positioning hole 721 is elliptical, the major semi-axis of the ellipse is arranged along the third direction, thereby providing the second positioning member 82 with an adjustment range along the third direction. This allows the second positioning member 82 to flexibly adjust its position when connecting the support longitudinal beam 70. This not only optimizes the alignment accuracy between the support longitudinal beam 70 and the second connecting plate 72 and reduces installation errors, but also enables the support longitudinal beam 70 to withstand thermal expansion and contraction caused by temperature changes, improving the elasticity of the side structure of the support longitudinal beam 70.

[0069] Please see Figures 7 to 10 In some embodiments, the crossbeam 10 has a first fixing hole 712 at the position corresponding to the first positioning hole 711, and the side structure of the crossbeam also includes a first positioning nut 811. The outer surface of the first positioning member 81 has an external thread adapted to the first positioning nut 811, and the first positioning member 81 passes through the first fixing hole 712 and is screwed with the first positioning nut 811.

[0070] Optionally, the threaded connection between the first positioning nut 811 and the first positioning member 81 provides a reliable fixing force, enhances the connection strength between the crossbeam 10 and the first connecting plate 71, and the screw-lock structure facilitates disassembly and maintenance.

[0071] Please see Figures 7 to 10 In some embodiments, the supporting longitudinal beam 70 is provided with a second fixing hole 702 at the position corresponding to the second positioning hole 721. The side structure of the crossbeam also includes a second positioning nut 822 located inside the supporting longitudinal beam 70. The outer surface of the second positioning member 82 is provided with an external thread adapted to the second positioning nut 822, and the second positioning member 82 passes through the second fixing hole 702 and is screwed with the second positioning nut 822.

[0072] Optionally, the threaded connection between the second positioning nut 822 and the second positioning member 82 ensures a stable connection between the support longitudinal beam 70 and the second connecting plate 72. The placement of the second positioning nut 822 inside the support longitudinal beam 70 optimizes the stress distribution and reduces stress concentration at the connection.

[0073] Optionally, both the support longitudinal beam 70 and the cross beam 10 are hollow structures, and the support base 701 can be welded onto the support longitudinal beam 70, so that the second connecting plate 72 is threaded onto the support base 701.

[0074] It is understandable that the second positioning nut 822 is located inside the support base 701, while the first positioning nut 811 is located between the first connecting plate 71 and the second connecting plate 72, so that they can be installed separately, improving the convenience of installing the first positioning nut 811 and the second positioning nut 822.

[0075] Please see Figures 7 to 10 In some embodiments, multiple first positioning elements 81 are arranged at intervals.

[0076] Optionally, the arrangement of multiple first positioning elements 81 increases the connection points between the crossbeam 10 and the first connecting plate 71, disperses the force on the edge of the crossbeam 10, and improves the shear and tensile strength of the connection, thereby enhancing the overall stability of the structure.

[0077] Please see Figures 7 to 10 In some embodiments, multiple second positioning elements 82 are arranged at intervals.

[0078] Optionally, the arrangement of multiple second positioning elements 82 improves the connection strength between the support longitudinal beam 70 and the second connecting plate 72. By dispersing the stress points, it improves the mechanical transmission capacity of the support longitudinal beam 70 in the second and third directions, thereby enhancing the torsional resistance and stability of the structure.

[0079] Please see Figures 7 to 10 In some embodiments, the first connecting plate 71 has a first toothed groove 713, and multiple first toothed grooves 713 are arranged at intervals. The side structure of the crossbeam also includes a first toothed gasket 812 that connects to the first positioning member 81, and the first toothed gasket 812 engages with multiple first toothed grooves 713.

[0080] Please see Figures 7 to 10 Optionally, multiple first toothed grooves 713 are arranged at intervals along the second direction. The meshing structure of the first toothed grooves 713 and the toothed gasket significantly increases the friction and biting force between the first positioning member 81 and the first connecting plate 71, preventing the first positioning member 81 from sliding or loosening under force, and further improving the shear resistance and stability of the connection.

[0081] Please see Figures 7 to 10 In some embodiments, the second connecting plate 72 is provided with a second toothed groove 722, and multiple second toothed grooves 722 are arranged at intervals. The side structure of the crossbeam also includes a second toothed gasket 821 that connects to the second positioning member 82, and the second toothed gasket 821 engages with multiple second toothed grooves 722.

[0082] Please see Figures 7 to 10 Optionally, multiple second toothed grooves 722 are arranged at intervals along the first direction. The engagement of multiple second toothed grooves 722 with the second toothed gasket 821 enhances the connection stability between the second positioning member 82 and the second connecting plate 72, reduces the risk of displacement or loosening of the supporting longitudinal beam 70 under stress, and improves the torsional and shear resistance of the structure.

[0083] Please see Figures 7 to 10 It is understandable that the first toothed gasket 812 and the second toothed gasket 821 are both sawtooth gaskets or anti-slip gaskets. They are metal gaskets with radial or spiral teeth on the surface, usually made of carbon steel or stainless steel. Their main function is to enhance the friction between the connecting pairs and prevent the bolt connection from loosening. They are especially suitable for connection environments with frequent vibration, impact or thermal expansion and contraction.

[0084] Please see Figures 11 to 14 The curtain wall system also includes a strength-equal connection structure, which includes fasteners 16 and reinforcing plates 163. The reinforcing plates 163 can be made of metal, such as aluminum alloy. Aluminum alloy has a density of 2.63 to 2.85 g / cm3, has high strength, a specific strength close to that of high alloy steel, and a specific stiffness exceeding that of steel. It also has good casting and plastic processing properties, good corrosion resistance, and can be used as a structural material.

[0085] Please see Figures 11 to 14 The crossbeam 10 includes multiple support plates 141, which sequentially enclose and form a first cavity 11, thereby reducing the weight of the crossbeam 10 while ensuring its structural strength and rigidity. A reinforcing plate 163 is disposed within the first cavity 11 and connected to one end of the crossbeam 10. During use, the surface of the reinforcing plate 163 is arranged vertically, and its edge is connected to the inner wall of the first cavity 11. It is understood that the edge of the reinforcing plate 163 can be welded to the inner wall of the first cavity 11. Alternatively, the reinforcing plate 163 can be fixed within the first cavity 11 using structural components; this is not a limitation and can be chosen according to the actual situation.

[0086] Please see Figures 11 to 12The reinforcing plate 163 has fastening holes 166. Two crossbeams 10 are arranged at intervals along the horizontal direction, with one end of each crossbeam 10 joined together. The two reinforcing plates 163 are arranged opposite each other. It is understood that the opening of the first cavity 11 is located at the end face of one end of the crossbeam 10, and the reinforcing plate 163 is positioned at the opening of the first cavity 11. The fastener 16 includes a fixing bolt 161 and a fastening nut 162. One end of the fixing bolt 161 passes through the two fastening holes 166, and the fastening nut 162 is screwed onto the other end of the fixing bolt 161. It is understood that washers can be provided on the fixing bolt 161 and the fastening nut 162 to improve the stability and reliability of the connection.

[0087] The reinforcement plate 163 enhances the strength and rigidity of the joint between the two crossbeams 10, ensuring an equal-strength connection, meaning the two crossbeams 10 essentially possess the strength of a single integral molding. The connection method using the fixing bolts 161 and nuts facilitates operation, avoids uneven strength issues caused by welding, and also facilitates installation and disassembly.

[0088] It is understandable that multiple crossbeams 10 can be arranged at the same horizontal level, and any two adjacent crossbeams 10 can be connected by an equal-strength connection structure to form a longer crossbeam.

[0089] Please see Figures 11 to 12 In some embodiments, the first cavity 11 is provided with a guide strip 17, which is arranged along the length of the crossbeam 10. The edge of the reinforcing plate 163 is provided with a guide groove 165, and part of the guide strip 17 is located in the guide groove 165.

[0090] Optionally, the cooperation between the guide strip 17 and the guide groove 165 improves the positioning accuracy of the reinforcing plate 163 in the first cavity 11 of the crossbeam 10. During the installation of the reinforcing plate 163 and the crossbeam 10, the cooperation between the guide strip 17 and the guide groove 165 ensures the stability of the reinforcing plate 163 during installation, while limiting the offset of the reinforcing plate 163 outside the length direction of the crossbeam 10, and enhancing the shear resistance of the connection.

[0091] Please see Figures 11 to 12 In some embodiments, multiple guide strips 17 are arranged at intervals, and each guide strip 17 is arranged around the circumference of the reinforcing plate 163. The reinforcing plate 163 has guide grooves 165 at the positions corresponding to each guide strip 17, and each guide strip 17 is partially located in each guide groove 165.

[0092] Please see Figures 11 to 12Optionally, the cooperation of multiple guide strips 17 and multiple guide grooves 165 improves the installation stability and anti-displacement capability of the reinforcing plate 163. The circumferentially arranged guide strips 17 evenly distribute the force on the reinforcing plate 163, enhancing the torsional resistance at the joint. It can be understood that the cross-sectional shape of the beam 10 is rectangular, the shape of the reinforcing plate 163 is adapted to the cross-sectional shape of the beam 10, four guide strips 17 are provided, each guide strip 17 is located at one of the four right angles of the first cavity 11, and the four guide grooves 165 are also located at one of the four right angles of the guide plate.

[0093] Please see Figures 11 to 12 In some embodiments, the equal-strength connection structure further includes a limiting ring 164, the limiting ring 164 being located in the first cavity 11, and the edge of the limiting ring 164 being connected to the inner wall of the first cavity 11. The limiting ring 164 is located outside the reinforcing plate 163, and the fixing bolt 161 passes through the two limiting rings 164 and is connected to the fastening nut 162.

[0094] Please see Figures 11 to 12 Optionally, the edge of the limiting ring 164 can be connected to the inner wall of the first cavity 11 by welding. The limiting ring 164 can prevent the reinforcing plate 163 from sliding out of the first cavity 11 along one end of the crossbeam 10. That is, the limiting ring 164 forms an external constraint on the reinforcing plate 163, limiting the displacement of the reinforcing plate 163 under the action of external force. When the fastener 16 locks the two crossbeams 10, it improves the stability of the joint. At the same time, the limiting ring 164 provides a force support point for the fixing bolt 161, distributing the force on the fastener 16.

[0095] Please see Figures 11 to 12 In some embodiments, multiple fasteners 16 are arranged at intervals. In this embodiment, three fasteners 16 are arranged at intervals. In other embodiments, four or more fasteners 16 may also be arranged at intervals. No limitation is made here.

[0096] Please see Figures 11 to 12 In some embodiments, the inner wall of the limiting ring 164 is inclined, the inclination of the side surface of the reinforcing plate 163 is adapted to the inner wall of the limiting ring 164, and the reinforcing plate 163 is partially embedded in the limiting ring 164.

[0097] Optionally, the inclined surface-adaptive fitting structure increases the contact area between the reinforcing plate 163 and the limiting ring 164, improves the friction and stability at the connection, restricts the lateral movement of the reinforcing plate 163, and at the same time, the inclined surface helps the reinforcing plate 163 to be embedded and fastened in the limiting ring 164, improving the lateral stability of the reinforcing plate 163.

[0098] Please see Figures 11 to 12In some embodiments, the reinforcing plate 163 has a predetermined thickness along the length of the crossbeam 10.

[0099] Optionally, the thickness of the reinforcing plate 163 is greater than the thickness of the inner wall of the first cavity 11. For example, the predetermined thickness can be 20 mm, while the thickness of the inner wall of the first cavity 11 can be 10 mm. The reinforcing plate 163 can provide sufficient strength and rigidity according to the mechanical requirements of the beam 10, enhance the load-bearing capacity at the joint, and avoid the decrease in strength due to insufficient thickness or the waste of material due to excessive thickness.

[0100] In some embodiments, the equal-strength connection structure further includes a reinforcing side plate 18, one end of which is connected to the side surface of one of the crossbeams 10, and the other end of which is connected to the side surface of the other crossbeam 10.

[0101] Please see Figures 11 to 12 Optionally, the reinforcing side plates 18 are arranged on both opposite sides of the crossbeam 10. The reinforcing side plates 18 can be screwed to the side surface of the crossbeam 10 by screws or bolts, thereby reinforcing the strength of the joint of the two crossbeams 10 from the side, improving the torsional and shear resistance of the joint, improving the overall stiffness of the joint structure, and reducing the relative displacement of the crossbeams 10 under stress.

[0102] Please see Figures 13 to 14 In some embodiments, the equal-strength connection structure further includes columns connecting the crossbeam 10 and inter-layer supports 168 connecting the columns, the columns being arranged at intervals, and the two ends of the inter-layer supports 168 being connected to the two columns respectively.

[0103] Optionally, the inter-floor support 168 transmits the load to the beam 10 through the columns, which can improve the overall stability of the curtain wall system.

[0104] Please see Figures 13 to 14 In some embodiments, the equal-strength connection structure further includes corner brackets 19, one end of which is connected to the interlayer support 168, and the other end of which is connected to the column.

[0105] Please see Figures 13 to 14 Optionally, the corner bracket 19 is L-shaped and can be bolted to the column and the interlayer support 168. The surface of the corner bracket 19 connected to the column has a waist-shaped hole 191. The bolt passes through the waist-shaped hole 191 and is threaded to the column. The waist-shaped hole 191 allows the bolt to move appropriately along the width of the beam 10 to improve the thermal expansion and contraction of the equal strength connection structure in response to temperature changes.

[0106] Please see Figures 13 to 14Optionally, the corner bracket 19 can enhance the connection strength between the interlayer support 168 and the column, optimize the mechanical transmission path, improve the stability of the curtain wall system under multi-directional forces (wind load, seismic force, etc.), and facilitate installation and adjustment.
