Description

Technical Field

[0001] This utility model belongs to the field of curtain wall technology and equipment, and particularly relates to a beam edge structure and curtain wall system. Background Technology

[0002] As a widely used external envelope system in modern architecture, building curtain walls are essentially non-load-bearing exterior wall structures. Their main function is to isolate and protect the interior of a building from its external environment, while also enhancing the overall appearance of the building. Building curtain walls typically consist of two main parts: first, the surface decorative and protective panels, which may be made of various materials such as glass, metal, stone, and ceramic; and second, the supporting system located behind the panels that bears the structural load. Common forms include aluminum alloy beams and columns, steel structural components, and beam end supports.

[0003] In the entire curtain wall system, aluminum alloy beams, as the core component of the supporting structure, not only undertake the mechanical function of effectively transmitting external forces such as panel loads, wind loads, and seismic forces to the main building structure, but also determine the structural stiffness, stability, and safety of the entire curtain wall system.

[0004] However, existing crossbeams are generally connected at both ends by welding. After welding, the free ends of the crossbeams are restricted. Although this can ensure that the crossbeams have sufficient rigidity and stability, the crossbeams are not elastic enough when there are temperature changes or external impacts. In the long term, they are prone to brittle fracture, mechanical fatigue or safety accidents. Utility Model Content

[0005] The purpose of this application is to provide a beam edge structure that addresses the problem of how to improve the elasticity of the beam edge structure.

[0027] Please see Figures 1 to 3 This application provides a beam edge structure and a curtain wall system having the same.

[0028] The crossbeam edge structure includes: a first connecting plate 71, a second connecting plate 72 connecting the first connecting plate 71, a crossbeam 10 arranged along a first direction, and a supporting longitudinal beam 70 arranged along a second direction. In this embodiment, the first direction is arranged horizontally, and the second direction is arranged vertically. It is 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, the crossbeam 10, 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.

[0029] Please see Figures 1 to 3The 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 721. 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 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 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.

[0030] Please see Figures 1 to 3 The beam edge structure provided in this application embodiment, through clearance fit, enables the beam 10 and the supporting longitudinal beam 70 to have the ability to make small displacements at the connection, thereby improving the elasticity of the beam edge structure, alleviating 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), improving the reliability and stability of use, and increasing the service life of the beam edge structure.

[0031] Please see Figures 1 to 3 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.

[0032] 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.

[0033] Please see Figures 1 to 3In 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.

[0034] 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.

[0035] Please see Figures 1 to 3 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.

[0036] 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.

[0037] Please see Figures 1 to 3 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Please see Figures 1 to 3 In some embodiments, multiple first positioning elements 81 are arranged at intervals.

[0042] 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.

[0043] Please see Figures 1 to 3 In some embodiments, multiple second positioning elements 82 are arranged at intervals.

[0044] 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.

[0045] Please see Figures 3 to 4 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.

[0046] Please see Figures 3 to 4 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.

[0047] Please see Figures 3 to 4 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.

[0048] Please see Figures 3 to 4 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.

[0049] Please see Figures 3 to 4 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.

[0050] Please see Figures 1 to 3 This utility model also proposes a curtain wall system, which includes a beam edge structure. The specific structure of the beam edge structure is as described in the above embodiments. Since this curtain wall system adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] In some embodiments, two supporting longitudinal beams 70 are arranged at intervals, and the two ends of the crossbeam 10 are respectively connected to the two supporting longitudinal beams 70.

[0052] Understandably, the curtain wall system includes the aforementioned horizontal beam edge structure, with two spaced-apart supporting longitudinal beams 70 connected to each end of the horizontal beam 10. Through the optimized horizontal beam edge structure, the curtain wall system achieves greater elasticity and stability at the connection between the horizontal beam 10 and the supporting longitudinal beams 70. The double supporting longitudinal beams 70 further distribute the load at both ends of the horizontal beam 10, enhancing the overall structural load-bearing capacity and resistance to deformation. Multiple horizontal beams 10 can be arranged at intervals along the second direction.

[0053] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
