Description

Technical Field

[0001] The invention belongs to the technical field of curtain wall connection structures, and particularly relates to an angle-adjustable keel and a special-shaped skylight. Background Art

[0002] In architecture, interior decoration, and various engineering structures, keels serve as key components for supporting and securing decorative materials and constructing the structural framework. Their performance directly impacts the stability and functionality of the overall structure. With the increasing diversity of architectural design styles and the continuous improvement of engineering construction requirements, the demand for keel adjustability is also increasing. This is especially true in projects that require special shapes and curved structures, where flexible adjustment of keel angles is particularly important.

[0003] Currently, most traditional keel structures are fixed-angle designs, making them difficult to adjust after installation. To achieve connections at different angles, pre-customized keel components with specific angles are often required. This not only increases production and construction costs, but also prolongs the construction period and reduces efficiency. Even if some keels have angle adjustment capabilities, their adjustment mechanisms are complex and cumbersome, making it difficult to precisely control the angle during adjustment. Furthermore, the stability after adjustment is poor, and they are prone to loosening or shifting, failing to meet the project's stringent requirements for structural stability and precision.

[0004] Based on this, the art urgently needs an angle-adjustable keel and a special-shaped skylight to solve the above technical problems. Summary of the Invention

[0043] Please refer to Figure 1-Figure 3 The present invention provides an angle-adjustable keel and a special-shaped skylight to solve the problem of how to flexibly adjust the keel angle in special shapes and curved structures.

[0044] For details, please refer to Figure 1 This is a structural diagram of an angle-adjustable keel and a special-shaped skylight provided by an embodiment of the present invention. Figure 2 This is a structural schematic diagram of the angle adjustment structure and secondary keel provided in an embodiment of the present invention, wherein the angle-adjustable keel 1 includes a main keel 10, an angle adjustment structure 20, and a secondary keel 30. The main keel 10 serves as a core supporting structure, bearing the load-bearing and stability requirements of the overall frame. The angle adjustment structure 20 includes an adjustment seat 21 and an adjustment rod 22 rotatably connected to the adjustment seat 21. The adjustment seat 21 is disposed inside the main keel 10, and the adjustment rod 22 extends outside the main keel 10. The adjustment seat 21 is fixed inside the main keel 10 and serves as a rotation fulcrum for the adjustment rod 22. In actual applications, the adjustment seat 21 can be designed as a fixed component with a bearing or an articulated device. The adjustment rod 22 is rotatably connected to the adjustment seat 21 through a pivot, gear, or threaded structure. The adjustment rod 22 extends to the outside of the main keel 10 for operation. When the adjustment rod 22 is rotated, its end drives the secondary keel 30 to rotate around the fulcrum, achieving an angle change; the secondary keel 30 is connected to the adjustment rod 22 so that the secondary keel 30 can rotate relative to the main keel 10. The secondary keel 30 is connected to the end of the adjustment rod 22 by bolts or clips, and changes its own tilt angle as the adjustment rod 22 moves, forming an adjustable auxiliary support structure. This allows the angle of the secondary keel 30 to be adjusted to accommodate complex design requirements such as curved ceilings and special-shaped walls. There is no need to customize keels of multiple specifications, reducing construction costs. During the actual installation process, workers only need to rotate the adjustment rod 22 to complete the angle calibration, without the need to repeatedly disassemble or cut the keel. At the same time, the built-in design of the adjustment seat 21 not only prevents the exposed parts from being interfered with by external forces, ensuring the long-term stability of the rotating structure, but also saves installation space, making it suitable for places with limited floor height.

[0045] In some specific embodiments, the adjusting rod 22 can adopt a screw structure, which produces axial displacement by cooperation of threads when rotating to push the secondary keel 30 to tilt; the adjusting seat 21 can also be internally provided with a gear set, and the adjusting rod 22 is driven by a rack or a pinion to achieve precise angle control; the adjusting rod 22 can also be locked in position by a spring pin or a bolt after the angle is changed by manual pulling.

[0046] As a further improvement of the present application, the adjusting rod 22 is respectively provided with a first connecting part 221 and a second connecting part 222 at both ends, and the first connecting part 221 and the second connecting part 222 are respectively arranged at both ends of the adjusting rod 22 to form two independent driving units; the secondary keel 30 includes a first secondary keel 31 and a second secondary keel 32, the first secondary keel 31 is provided with a third connecting part 311, and the second secondary keel 32 is provided with a fourth connecting part 321; the first connecting part 221 is connected with the third connecting part 311 to make the first secondary keel 31 rotate relative to the main keel 10, and the second connecting part 222 is connected with the fourth connecting part 321 to make the first secondary keel 31 rotate relative to the main keel 10. The first connecting part 221 cooperates with the third connecting part 311 of the first secondary keel 31, and the second connecting part 222 cooperates with the fourth connecting part 321 of the second secondary keel 32 to realize separate control or linkage adjustment of the two ends of the secondary keel 30. In actual application, the first connecting part 221 and the second connecting part 222 can be designed as hinges or adjustable lock buckles, and correspondingly, the third connecting part 311 and the fourth connecting part 321 can be designed as bearings or sliding groove structures, and the first secondary keel 31 and the second secondary keel 32 are connected with the adjusting rod 22 through independent first connecting part 221 and second connecting part 222 to form two sets of independently adjustable subsystems. When the adjusting rod 22 rotates to a certain angle, two secondary keels 30 can also be adjusted to rotate around their respective fulcrums, for example, the first secondary keel 31 is tilted upward, and the second secondary keel 32 is tilted downward to realize differential angle adjustment. By driving two secondary keels 30 with a single adjusting rod 22, symmetrical or asymmetrical angle changes such as V-shaped and wave-shaped structures can be realized to meet the demand for complex modeling and reduce the number of adjusting components. The first connecting part 221 and the second connecting part 222 can adopt different mechanical structures, such as fine adjustment by threads and quick adjustment by buckles, to adapt to the first secondary keel 31 for precise angle adjustment and the second secondary keel 32 for quick coarse adjustment, thereby improving the functionality and targeting. The branch points of the first secondary keel 31 and the second secondary keel 32 are designed to disperse the stress of the main keel 10, avoiding stress concentration at a single point, which is suitable for large-span scenarios such as exhibition hall trusses, sports stadium roofs, etc. At the same time, the first secondary keel 31 and the second secondary keel 32 are fixed with the adjusting rod 22 through the first connecting part 221 and the second connecting part 222, so that when a local damage occurs, the main structure does not need to be disassembled, and only the single secondary keel 30 needs to be replaced, thereby reducing maintenance costs.

[0047] As a further improvement of the present invention, the first connecting portion 221 includes a first connecting shaft 2211, both ends of which extend out of the adjusting rod 22; the second connecting portion 222 includes a second connecting shaft 2221, both ends of which extend out of the adjusting rod 22; the third connecting portion 311 includes a first shaft groove 3111, the first connecting shaft 2211 snaps into the first shaft groove 3111; and the fourth connecting portion 321 includes a second shaft groove 3211, the second connecting shaft 2221 snaps into the second shaft groove 3211. The first connecting shaft 2211 and the second connecting shaft 2221 at both ends of the adjusting rod 22 form a rotational pair with the first shaft groove 3111 of the primary keel 31 and the second shaft groove 3211 of the secondary keel 32, respectively. During installation, the portions of the first connecting shaft 2211 extending out of the adjusting rod 22 snap into the first shaft groove 3111, and the portions of the second connecting shaft 2221 extending out of the adjusting rod 22 snap into the second shaft groove 3211. This snap-in design allows the connecting shaft to rotate freely within the shaft groove, while the shaft groove limits the axial and radial movement of the connecting shaft, ensuring the stability of the connection. When it is necessary to adjust the angle of the secondary keel 30 relative to the main keel 10, an external force acts on the primary keel 31 or the secondary keel 32, driving the connecting shaft connected thereto to rotate within the shaft groove. Since both ends of the connecting shaft extend outside the adjusting rod 22 and cooperate with the shaft groove, a stable rotation fulcrum is formed, allowing the secondary keel 30 to rotate relative to the main keel 10 around the axis of the connecting shaft. The adjustment seat 21 provides support for the adjusting rod 22 inside the main keel 10, further ensuring the stability and controllability of the entire rotation process, and realizing flexible adjustment of the secondary keel 30 at multiple angles. When the adjustment rod 22 is rotated by an external force, the driving force is converted into a lever effect through the fulcrum of the adjustment seat 21, driving the first keel 31 and the second keel 32 to deflect synchronously. The first connecting shaft 2211, the second connecting shaft 2221 and the first shaft groove 3111, the second shaft groove 3211 cooperate to achieve fine-tuning of the angles of the first keel 31 and the second keel 32, thereby achieving multi-angle adjustment of the first keel 31 and the second keel 32. The snap-in connection method makes the assembly process of the adjustment rod 22 and the secondary keel 30 simple and quick. Construction personnel only need to align the connecting shaft with the shaft groove and snap it in to complete the connection, without the need for complex tools or tedious operations. This simple assembly method greatly shortens construction time, improves construction efficiency, and reduces labor costs.

[0048] As a further improvement of the present invention, the first axial groove 3111 is arranged perpendicular to the second axial groove 3211, and one of the first axial groove 3111 and the second axial groove 3211 is arranged parallel to the adjustment rod 22. The axial groove parallel to the adjustment rod 22 controls the degree of freedom of translation along the adjustment rod 22, allowing the secondary keel 30 to slide along the axial groove relative to the adjustment rod 22 to achieve telescopic adjustment. The axial groove perpendicular to the adjustment rod 22 limits the degree of freedom of axial rotation, allowing the secondary keel 30 to rotate along the connecting axis relative to the adjustment rod 22 to achieve micro-angle adjustment. Preferably, the first axial groove 3111 is parallel to the adjustment rod 22, and the second axial groove 3211 is arranged perpendicular to the adjustment rod 22. When the primary keel 31 needs to be adjusted, the primary keel 31 is pushed or pulled by external force, and the first connecting axis 2211 slides in the first axial groove 3111, thereby achieving telescopic adjustment of the primary keel 31 relative to the main keel 10 and changing its extended length. The second axis slot 3211 is arranged perpendicular to the adjustment rod 22. After the second connecting shaft 2221 is inserted into the second axis slot 3211, it can only rotate about its own axis within a plane perpendicular to the adjustment rod 22. When an external force acts on the secondary keel 32, it drives the second connecting shaft 2221 to rotate within the second axis slot 3211, thereby achieving slight angular adjustment of the secondary keel 32 relative to the adjustment rod 22. The design of allocating translational and rotational degrees of freedom to different axis slots enables the two secondary keels 30 to independently perform telescopic and angular adjustment functions without interfering with each other. When the spatial structure needs to be adjusted, the construction personnel can first adjust the extension length of the secondary keel 30 by sliding the parallel axis slot, then adjust the slight angle by rotating the perpendicular axis slot, and finally adjust the overall orientation by rotating the adjustment seat 21 within the main keel 10. The three functions work together to achieve all-round adjustment in three-dimensional space. Through the telescopic adjustment of the primary keel 31 and the slight angular adjustment of the secondary keel 32, a variety of complex spatial shapes can be constructed. In interior decoration, it can create a layered, special-shaped ceiling; in building facade decoration, it can create a unique curved surface shape to meet the diverse and personalized design needs of modern buildings.

[0049] The rotational connection between the adjustment seat 21 and the adjustment rod 22 enables primary angle adjustment. The adjustment seat 21 is fixed inside the main keel 10, and the adjustment rod 22 can rotate within the adjustment seat 21, driving the connected primary keel 31 and the secondary keel 31 to perform basic angle adjustment relative to the main keel 10, achieving overall azimuth rotation. The coordination of the shaft groove and the connecting shaft constitutes a secondary adjustment structure. The first shaft groove 3111 is parallel to the adjustment rod 22. The first connecting shaft 2211 can not only rotate with the adjustment rod 22 in the first shaft groove 3111 for primary angle adjustment, but can also slide axially to achieve telescopic adjustment of the primary keel 31. The second shaft groove 3211 is perpendicular to the adjustment rod 22. The second connecting shaft 2221 can only rotate within the vertical plane within the second shaft groove 3211, completing the secondary keel 32's minute angle adjustment. In practice, construction personnel can first perform a preliminary orientation adjustment on the secondary keel 30 by rotating the adjustment rod 22 within the adjustment seat 21 to determine the approximate angle. Then, based on specific needs, the first and second axis slots 3111 and 3211 can be used to perform fine adjustments to the extension and retraction of the primary keel 31 and secondary keel 32, respectively. The adjustment seat 21 provides stable support for the adjustment rod 22 within the primary keel 10, ensuring that the two adjustment stages work seamlessly and independently, ultimately enabling comprehensive, multi-level, and precise angle adjustment of the keel in three dimensions.

[0050] As a further improvement of the present invention, see Figure 3A first clamping block 312 is provided between the primary keel 31 and the adjustment rod 22. The first clamping block 312 has a third axial slot 3121, into which the first connecting shaft 2211 engages. A second clamping block 322 is provided between the secondary keel 32 and the adjustment rod 22. The second clamping block 322 has a fourth axial slot 3221, into which the second connecting shaft 2221 engages. The first clamping block 312 and the second clamping block 322 serve as intermediate connectors, respectively, enhancing the connection strength between the secondary keel 30 and the adjustment rod 22. The first clamping block 312 engages with the first connecting shaft 2211 via the third axial slot 3121, allowing the extension and rotation of the primary keel 31 to be transmitted to the adjustment rod 22 via the clamping block. The second clamping block 322 engages with the second connecting shaft 2221 via the fourth axial slot 3221, enabling fine angular adjustment of the secondary keel 32. This design distributes the external force that was originally borne directly by the secondary keel 30 to the block, reducing the wear of the connecting shaft and the shaft groove. The presence of the block also increases the redundancy of the adjustment system. When one of the connection points becomes loose, the other block can still maintain the stability of the structure. During the actual installation process, the main keel 10, the adjustment seat 21 and the adjustment rod 22 are pre-assembled to form the basic first-level angle adjustment structure 20. The first connecting shaft 2211 and the second connecting shaft 2221 at both ends of the adjustment rod 22 extend out of the main keel 10 to prepare for the installation of subsequent components. According to actual construction requirements, the first block 312 and the second block 322 are respectively installed between the adjustment rod 22 and the first keel 31 and the second keel 32. The third axial groove 3121 on the first clamping block 312 is precisely adapted to the first connecting shaft 2211. During installation, the third axial groove 3121 of the first clamping block 312 is aligned with the first connecting shaft 2211 and then clamped in, so that the first clamping block 312 is firmly connected to the adjusting rod 22. At the same time, the first keel 31 cooperates with the other side of the first clamping block 312 through its own first axial groove 3111 to achieve the first connection between the keel 31 and the adjusting rod 22; similarly, the fourth axial groove 3221 of the second clamping block 322 is engaged with the second connecting shaft 2221, and the second axial groove 3211 of the second keel 32 cooperates with the second clamping block 322 to complete the second connection between the keel 32 and the adjusting rod 22. At this point, the post-installed clamping block acts as an intermediate transition component, not only strengthening the connection between the secondary keel 30 and the adjustment rod 22, but also ensuring precise positioning, with the first axis slot 3111 parallel to the adjustment rod 22 and the second axis slot 3211 perpendicular to the adjustment rod 22. This allows the primary keel 31 to be telescopically adjusted along the adjustment rod 22, while the secondary keel 32 can achieve fine-angle adjustment. Furthermore, if the keel angle and position need to be adjusted during subsequent use, the clamping block can be removed and reinstalled, or its position on the connecting axis can be adjusted flexibly.

[0051] The first clamping block 312 is disposed between the primary keel 31 and the adjustment rod 22, and its third axial groove 3121 tightly engages with the first connecting shaft 2211 and cooperates with the first axial groove 3111 of the primary keel 31. After adjustment is completed, the first clamping block 312 forms a dual radial and axial constraint on the first connecting shaft 2211 through the third axial groove 3121, evenly transmitting the external force applied to the primary keel 31 after telescopic adjustment to the adjustment rod 22 and the main keel 10, thereby preventing the connection from loosening due to uneven force. Similarly, the fourth axial groove 3221 on the second clamping block 322 precisely fits the second connecting shaft 2221 and cooperates with the second axial groove 3211 of the secondary keel 32. After the secondary keel 32 completes the slight angle adjustment, the second clamping block 322 limits the displacement of the second connecting shaft 2221 in the vertical plane, firmly maintaining the angle of the secondary keel 32 and preventing it from rotating and deviating due to factors such as vibration and external force during use. The provision of the clamping block effectively solves the problem of the keel structure becoming loose after adjustment. Whether it is subjected to frequent operations during construction or to daily vibrations, wind loads, and other external forces during the use of the building, the clamping block can stably secure the secondary keel 30, preventing deformation and detachment of the keel due to loose connections, ensuring the safety of the building structure and avoiding safety hazards and property losses caused by structural instability. The clamping block reduces loosening and wear at the connection points, and over long-term use, the wear and tear of components such as the adjustment rod 22, connecting shaft, and shaft groove is significantly reduced. This allows the keel structure to maintain good performance after multiple adjustments and long-term use, extending the service life of the entire keel system, reducing the frequency of replacement and repair, and lowering maintenance costs.

[0052] As a further improvement of the present invention, one of the first block 312 and the second block 322 is a rigid block, and the other is a flexible block. Preferably, the first block 312 is a rigid block, and the second block 322 is a flexible block. The difference in material properties between the first block 312 and the second block 322 forms a stable structure that is both rigid and flexible. When the first block 312 is a rigid block, it can be made of metal or high-strength engineering plastic with good deformation resistance. After the rigid block is tightly engaged with the first connecting shaft 2211 through the third shaft groove 3121, it can provide precise positioning and strong support for the telescopic adjustment of the first keel 31, effectively resisting axial displacement and radial shaking caused by load changes. The rigid block directly transmits external force to the main keel 10, ensuring that the position remains stable after telescopic adjustment. The second block 322, as a flexible block, can be made of elastic rubber or a composite material with a certain elastic deformation ability. After the second keel 32 completes the slight angle adjustment, the flexible block cooperates with the second connecting shaft 2221 through the fourth axial groove 3221, which can not only limit the excessive rotation of the connecting shaft, but also absorb the stress caused by factors such as vibration and temperature change through its own elastic deformation. The elastic properties of the flexible block can also compensate for manufacturing tolerances and installation errors, ensuring the tightness and stability of the connection. The first block 312 acts as a rigid block. When the first keel 31 is telescopically adjusted, the third axial groove 3121 on the first block 312 is tightly matched with the first connecting shaft 2211 of the adjustment rod 22. With its rigid properties, it can firmly limit the axial movement of the first connecting shaft 2211, preventing the first keel 31 from falling off the adjustment rod 22 during the telescopic process. The rigid block evenly transfers the external force generated by the telescopic adjustment to the main keel 10, ensuring the stability and reliability of the telescopic adjustment. The second block 322 acts as a flexible block. When the second keel 32 is adjusted to a slight angle, the fourth axis slot 3221 on the second block 322 cooperates with the second connecting shaft 2221 of the adjustment rod 22. The elasticity of the flexible block enables the second connecting shaft 2221 to rotate to a certain extent within the fourth axis slot 3221, thereby achieving the second angle change of the keel 32 relative to the adjustment rod 22. The flexible block can absorb and buffer external forces during rotation, avoiding damage to the connection parts caused by excessive rigidity, while ensuring the flexibility and smoothness of angle adjustment. In the entire keel structure, the rigid first block 312 and the flexible second block 322 cooperate with each other. The rigid block ensures the stability of the structure during telescopic adjustment, and the flexible block provides freedom of angle adjustment, so that the keel system can not only meet the stability requirements of telescopic adjustment, but also achieve flexible adjustment at multiple angles to adapt to different architectural designs and construction requirements.

[0053] In environments with large temperature fluctuations, the combined design of rigid and flexible card blocks can effectively solve the problems caused by thermal expansion and contraction of materials. The rigid card blocks maintain the basic shape and dimensional accuracy of the structure, while the flexible card blocks compensate for dimensional differences caused by temperature changes through elastic expansion and contraction, avoiding structural deformation or loose connections caused by thermal stress, and ensuring that the keel system can maintain stable performance in different temperature environments. At the same time, the elastic properties of the flexible card blocks can effectively suppress the transmission of vibrations caused by people walking and equipment operation, thereby reducing the noise level inside the building. In places with high requirements for the acoustic environment, such as concert halls and conference rooms, this combination of rigid and flexible card block design can enhance the acoustic quality of the space and improve the user experience.

[0054] As a further improvement of the present invention, the adjustment seat 21 comprises an adjustment plate 211, a U-shaped rotating seat 212 mounted on the adjustment plate 211, and a rotating shaft 213 extending through the rotating seat. The adjustment rod 22 is mounted within the U-shaped rotating seat 212, and the rotating shaft 213 extends through the adjustment rod 22, allowing the adjustment rod 22 to rotate about the rotating shaft 213. The adjustment plate 211 serves as a base support component, providing a mounting surface for the entire adjustment seat 21. Adjusting the thickness of the adjustment plate 211 also allows for height adjustment. The U-shaped rotating seat 212 is mounted perpendicular to the adjustment plate 211. Its U-shaped opening provides space for the adjustment rod 22, allowing it to be smoothly positioned within the U-shaped rotating seat. The rotating shaft 213 extends through both sides of the U-shaped rotating seat and the adjustment rod 22, forming a rotating axis. When the angle of the secondary keel 30 relative to the primary keel 10 needs to be adjusted, an external force acts on the adjustment rod 22, causing it to rotate about the rotating shaft 213 within the U-shaped rotating seat. Because the shaft 213 extends through the adjustment rod 22 and the U-shaped rotating seat restricts the radial movement of the adjustment rod 22, the adjustment rod 22 can only rotate about the shaft 213, thereby achieving precise angle adjustment. During rotation, the adjustment seat 21 provides stable support, ensuring smooth and controllable rotation of the adjustment rod 22. This, in conjunction with the shaft slot and connecting shaft, allows for telescopic and pitch adjustment of the secondary keel 30, enabling flexible, multi-angle adjustment of the keel in three dimensions.

[0055] As a further improvement of the present application, the adjusting rod 22 is arranged vertically with the main keel 10. The adjusting rod 22 is arranged vertically at 90° with the main keel 10, forming a T-shaped framework basic configuration, and the torque generated by the rotation of the adjusting rod 22 is directly converted into the in-plane overturning moment of the secondary keel 30, avoiding the energy loss caused by the oblique force transmission. The adjusting seat 21 inside the main keel 10 serves as a fixed fulcrum, and the adjusting rod 22 rotates around its axis, amplifying the operation torque through the lever effect of the vertical rod body, realizing the lightweight operation of large-angle adjustment of the secondary keel 30. The T-shaped structure makes the keel system have better lateral force resistance. When subjected to horizontal wind or earthquake force, the vertically arranged adjusting rod 22 and the main keel 10 form a stable frame structure, which can effectively disperse and resist lateral load, reduce structural deformation, and improve the safety of the building. The vertically arranged adjusting rod 22 provides a clear installation reference for construction personnel, facilitating quick positioning and calibration. When working at a high altitude, the vertical relationship between the adjusting rod 22 and the main keel 10 can be used to quickly judge whether the installation angle is correct, reduce measurement errors, and improve construction efficiency.

[0056] The present application also provides a special-shaped skylight, please see Figure 4 , comprising the above-mentioned angle-adjustable keel 1, further comprising a mounting body 2 and a glass plate 3; the adjusting piece 211 is connected with a mounting shaft 2111, the mounting shaft 2111 is arranged in the mounting body 2 to connect the adjusting seat 21 with the mounting body 2; the glass plate 3 is connected with the main keel 10 and the secondary keel 30. The mounting body 2 serves as the static base of the skylight and is usually fixed to the building structure, such as a roof steel beam or a concrete ring beam, with a pre-set shaft hole or sliding rail inside for accommodating the mounting shaft 2111. The movable connection between the adjusting piece 211 and the mounting body 2 through the mounting shaft allows the entire angle-adjustable keel 1 system to fine-tune the installation position in the height direction relative to the building body, compensating for construction errors. The glass plate 3 is bonded to the main keel and the secondary keel 30 through flexible rubber pads, and the dead weight and wind load are transmitted to the adjusting seat 21 through the keel and finally dispersed to the mounting body 2 by the mounting shaft. The angle of the secondary keel 30 is controlled by the adjusting rod 22, and the cold bending of multiple glass plates 3 forms a continuous variable curved surface, such as a hyperbolic paraboloid or a spiral shape, breaking through the limitations of traditional skylights with a single plane or fixed arc, and adapting to parameterized building skins. Elastic sealing strips are pre-installed at the joints of the glass plate 3, which can automatically stretch and contract with the change of the keel angle, maintaining the air and water tightness of the skylight. Through the angle-adjustable keel 1, the skylight can form complex geometric shapes such as hyperbolic and folded surfaces, breaking through the limitations of traditional skylights with a single plane or single curved surface, and meeting the dual demands of aesthetics and function in modern architecture. For example, in public buildings such as museums and exhibition halls, flowing light and shadow effects can be created.

[0057] In some embodiments, the glass panel 3 can also be a photovoltaic panel, a metal panel, a composite material, a translucent concrete, an ETFE film material, wood, ceramics, acrylic, a green plant panel, an intelligent dimming panel, etc. In actual application, it can be selected according to actual needs, and the present invention does not limit it here.

[0058] As a further improvement to the present invention, a decorative profile 33 is disposed on the exterior of the secondary purlin 30. The connection between the decorative profile 33 and the primary purlin 10 is provided with waterproof material 34. The decorative profile 33, connected to the exterior of the secondary purlin 30, not only enhances the skylight's aesthetic appeal but also effectively directs rainwater toward the drainage system. The internal cavity of the decorative profile 33 can accommodate pipelines, providing additional functions such as sunshade and ventilation. Waterproof material 34 is provided at the connection between the primary purlin 10 and the decorative profile 33. The waterproof material deforms through pre-compression, filling the gap in the connection and forming a continuous waterproof barrier. When the primary purlin 10 experiences slight deformation due to temperature fluctuations or structural loads, the flexible waterproof material maintains its sealing properties through its own elastic deformation. The diverse designs of the decorative profile 33 can harmonize with the overall architectural style and enhance its aesthetic value. Furthermore, the internal cavity of the profile can be integrated with functional modules such as sunshade blinds and LED light strips, achieving a design that integrates decorative and functional elements and improves space utilization. The combination of the decorative profile 33 and waterproof material 34 forms an acoustic barrier, effectively blocking external noise from entering the interior. In heavy traffic or noisy environments, this design can significantly improve the indoor acoustic environment and enhance the user experience.
