Description

Technical Field

[0001] This utility model belongs to the field of curtain wall connection structure technology, specifically relating to an angle-adjustable keel and an irregularly shaped skylight. Background Technology

[0002] In architecture, interior decoration, and various engineering structures, the keel serves as a key component for supporting and fixing decorative materials and constructing structural frames. Its performance directly affects the stability and functionality of the overall structure. With the increasing diversification of architectural design styles and the continuous improvement of engineering construction requirements, the demand for the adjustability of the keel is also increasing. This is especially true in projects that require the realization of special shapes and curved structures, where the flexible adjustment of the keel angle is particularly important.

[0003] Currently, most traditional keel structures are designed with fixed angles, making it difficult to adjust the angle after installation. To achieve connections at different angles, it is often necessary to pre-customize keel components with specific angles, which not only increases production and construction costs but also prolongs the construction period and reduces construction efficiency. Even if some keels have angle adjustment functions, their adjustment structures are relatively complex and cumbersome to operate. It is difficult to accurately control the angle during the adjustment process, and the stability after adjustment is poor, easily leading to loosening or displacement, failing to meet the strict requirements of engineering projects for structural stability and precision.

[0004] Therefore, there is an urgent need in this field for an angle-adjustable keel and an irregularly shaped skylight to solve the above-mentioned technical problems. Utility Model Content

[0043] Please refer to Figures 1-3 This utility model provides an angle-adjustable keel and an irregularly shaped skylight to solve the problem of how to flexibly adjust the angle of the keel in special shapes and curved structures.

[0044] Specifically, please refer to Figure 1 This is a structural diagram of an adjustable-angle keel and an irregularly shaped skylight provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the angle adjustment structure and secondary keel provided in an embodiment of the present invention. 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 the core support structure, bearing the load 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 located inside the main keel 10, and the adjustment rod 22 extends out of the main keel 10. The adjustment seat 21 is fixed inside the main keel 10 and serves as the rotation fulcrum of the adjustment rod 22. In practical applications, the adjustment seat 21 can be designed as a fixed component with a bearing or hinge device. The adjustment rod 22 is rotatably connected to the adjustment seat 21 via a pivot, gear, or threaded structure, and the adjustment rod 22 extends out of the main keel 10 for operation. When the adjusting rod 22 is rotated, its end drives the secondary keel 30 to rotate around the fulcrum, thus changing the angle. The secondary keel 30 is connected to the adjusting rod 22 so that it rotates relative to the main keel 10. The secondary keel 30 is connected to the end of the adjusting rod 22 by bolts or clips, and changes its tilt angle as the adjusting rod 22 moves, forming an adjustable auxiliary support structure. This allows for adjustment of the angle of the secondary keel 30, adapting to complex design requirements such as curved ceilings and irregularly shaped walls. It eliminates the need for custom-made multi-specification keels, reducing construction costs. In actual installation, workers only need to rotate the adjusting rod 22 to complete the angle calibration, without repeatedly disassembling or cutting the keel. Simultaneously, the built-in design of the adjusting seat 21 avoids external interference to exposed components, ensuring the long-term stability of the rotating structure, and also saves installation space, making it suitable for locations with limited ceiling height.

[0045] In some specific embodiments, the adjusting rod 22 can adopt a screw structure, which generates axial displacement through the engagement of the screw with the adjusting seat 21 when rotating, pushing the secondary keel 30 to tilt; the adjusting seat 21 can also have a built-in gear set, and the adjusting rod 22 is driven by a rack or pinion to achieve precise angle control; the adjusting rod 22 can also be manually turned to change the angle and then locked in position by a spring pin or bolt.

[0046] As a further improvement of this utility model, the adjusting rod 22 is provided with a first connecting part 221 and a second connecting part 222 at both ends, forming two independent driving units; the secondary keel 30 includes a first keel 31 and a second keel 32, the first keel 31 is provided with a third connecting part 311, and the second keel 32 is provided with a fourth connecting part 321; the first connecting part 221 and the third connecting part 311 cooperate to allow the first keel 31 to rotate relative to the main keel 10, and the second connecting part 222 and the fourth connecting part 321 cooperate to allow the first keel 31 to rotate relative to the main keel 10. The first connecting part 221 cooperates with the third connecting part 311 of the first keel 31, and the second connecting part 222 cooperates with the fourth connecting part 321 of the second keel 32, realizing the separate control or linkage adjustment of the two secondary keels 30. In practical applications, the first connecting part 221 and the second connecting part 222 can be designed with hinges or adjustable locking structures. Correspondingly, the third connecting part 311 and the fourth connecting part 321 can be designed as bearings or sliding groove structures. The first keel 31 and the second keel 32 are connected to the adjusting rod 22 through independent first connecting parts 221 and second connecting parts 222, forming two independently adjustable subsystems. After the adjusting rod 22 rotates, the two secondary keels 30 can also be adjusted to rotate around their respective fulcrums simultaneously. For example, the first keel 31 tilts upward and the second keel 32 tilts downward to achieve differential angle adjustment. By driving the two secondary keels 30 simultaneously with a single adjusting rod 22, symmetrical or asymmetrical angle changes can be achieved, such as V-shaped or wave-shaped structures, to meet the needs of complex shapes and reduce the number of adjusting parts. The first connecting part 221 and the second connecting part 222 can adopt different mechanical structures, such as threaded fine adjustment and snap-fit ​​quick adjustment, to respectively adapt to the first keel 31 for precise angle adjustment and the second keel 32 for rapid coarse adjustment, improving the functional specificity. The branch point design of the first keel 31 and the second keel 32 disperses the force on the main keel 10, avoiding stress concentration at a single point. It is suitable for large-span scenarios, such as exhibition hall trusses and stadium roofs. At the same time, the first keel 31 and the second keel 32 are fixed to the adjusting rod 22 through the first connecting part 221 and the second connecting part 222. In case of local damage, there is no need to disassemble the main structure. Only a single secondary keel 30 can be replaced directly, reducing maintenance costs.

[0047] As a further improvement of this utility model, the first connecting part 221 includes a first connecting shaft 2211, both ends of which extend outside the adjusting rod 22; the second connecting part 222 includes a second connecting shaft 2221, both ends of which extend outside the adjusting rod 22; the third connecting part 311 includes a first shaft groove 3111, into which the first connecting shaft 2211 is inserted; the fourth connecting part 321 includes a second shaft groove 3211, into which the second connecting shaft 2221 is inserted. The first connecting shaft 2211 and the second connecting shaft 2221 at both ends of the adjusting rod 22 form rotating pairs with the first shaft groove 3111 of the first keel 31 and the second shaft groove 3211 of the second keel 32, respectively. During installation, the portions of the first connecting shaft 2211 extending beyond the adjusting rods 22 at both ends engage with the first shaft groove 3111, and the portions of the second connecting shaft 2221 extending beyond the adjusting rods 22 at both ends engage with the second shaft groove 3211. This engaging design allows the connecting shafts to rotate freely within the shaft grooves, while the shaft grooves restrict the axial and radial movement of the connecting shafts, ensuring connection stability. When it is necessary to adjust the angle of the secondary keel 30 relative to the main keel 10, an external force is applied to the first keel 31 or the second keel 32, causing the connected connecting shaft to rotate within the shaft groove. Since both ends of the connecting shaft extend beyond the adjusting rods 22 and engage with the shaft grooves, 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 adjusting seat 21 provides support for the adjusting rods 22 inside the main keel 10, further ensuring the smoothness and controllability of the entire rotation process, and enabling flexible adjustment of the secondary keel 30 at multiple angles. When the adjusting rod 22 rotates under external force, the driving force is converted into a lever effect through the fulcrum of the adjusting seat 21, causing the first keel 31 and the second keel 32 to deflect synchronously. The cooperation of the first connecting shaft 2211, the second connecting shaft 2221 with the first shaft groove 3111, and the second shaft groove 3211 enables fine-tuning of the angles of the first keel 31 and the second keel 32, achieving multi-angle adjustment of the first keel 31 and the second keel 32. The snap-fit ​​connection method makes the assembly process of the adjusting 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 complicated tools or cumbersome operations. This simple assembly method greatly shortens the construction time, improves construction efficiency, and reduces labor costs.

[0048] As a further improvement of this utility model, the first shaft groove 3111 and the second shaft groove 3211 are arranged perpendicularly, and one of the first shaft groove 3111 and the second shaft groove 3211 is arranged parallel to the adjusting rod 22. The shaft groove parallel to the adjusting rod 22 controls the translational freedom along the adjusting rod 22, allowing the secondary keel 30 to slide relative to the adjusting rod 22 along the shaft groove, thereby realizing telescopic adjustment. The shaft groove perpendicular to the adjusting rod 22 restricts the rotational freedom of the axis, allowing the secondary keel 30 to rotate relative to the adjusting rod 22 along the connecting shaft, thereby realizing micro-angle adjustment. Preferably, the first shaft groove 3111 is parallel to the adjusting rod 22, and the second shaft groove 3211 is perpendicular to the adjusting rod 22. When it is necessary to adjust the primary keel 31, the primary keel 31 is pushed or pulled by external force, and the first connecting shaft 2211 slides in the first shaft groove 3111, thereby realizing the telescopic adjustment of the primary keel 31 relative to the main keel 10 and changing its extension length. The second shaft groove 3211 is perpendicular to the adjusting rod 22. After the second connecting shaft 2221 is embedded in the second shaft groove 3211, it can only rotate around its own axis in a plane perpendicular to the adjusting rod 22. When an external force is applied to the second keel 32, it drives the second connecting shaft 2221 to rotate within the second shaft groove 3211, thereby achieving a small angle adjustment of the second keel 32 relative to the adjusting rod 22. The design of distributing translational and rotational degrees of freedom to different shaft grooves allows the two secondary keels 30 to independently complete the functions of extension and angle adjustment without interfering with each other. When it is necessary to adjust the spatial structure, the construction personnel can first adjust the extension length of the secondary keel 30 by sliding it through the parallel shaft groove, then adjust the small angle by rotating it through the vertical shaft groove, and finally achieve the overall orientation adjustment by rotating the adjusting seat 21 within the main keel 10. The three work together to achieve all-round adjustment in three-dimensional space. Through the extension and contraction adjustment of the first keel 31 and the small angle adjustment of the second keel 32, a variety of complex spatial shapes can be constructed. In interior decoration, it can create layered, irregularly shaped ceilings; in building facade decoration, it can create unique curved shapes to meet the diverse and personalized design needs of modern architecture.

[0049] The rotational connection between the adjusting seat 21 and the adjusting rod 22 achieves the first-level angle adjustment. The adjusting seat 21 is fixed inside the main keel 10, and the adjusting rod 22 can rotate within the adjusting seat 21, driving the first keel 31 and the second keel 32 connected to it to perform basic angle adjustments relative to the main keel 10, thus achieving overall orientation rotation. The fit between the shaft groove and the connecting shaft constitutes the second-level adjustment structure. The first shaft groove 3111 is parallel to the adjusting rod 22. The first connecting shaft 2211 can not only rotate with the adjusting rod 22 during the first-level angle adjustment within the first shaft groove 3111, but also slide axially, realizing the extension and retraction adjustment of the first keel 31. The second shaft groove 3211 is perpendicular to the adjusting rod 22. The second connecting shaft 2221 can only rotate in the vertical plane within the second shaft groove 3211, completing the second minute angle adjustment of the keel 32. In practical applications, construction workers can first adjust the orientation of the secondary keel 30 by rotating the adjusting rod 22 within the adjusting seat 21 to determine the approximate angle. Then, according to specific needs, the first keel 31 and the second keel 32 can be finely adjusted for extension and retraction and minute angle adjustments using the first shaft groove 3111 and the second shaft groove 3211, respectively. The adjusting seat 21 provides stable support for the adjusting rod 22 inside the main keel 10, ensuring that the two-stage adjustment processes do not interfere with each other and work closely together, ultimately achieving precise angle adjustment of the keel in all directions and at multiple levels in three-dimensional space.

[0050] As a further improvement to this utility model, please refer to Figure 3A first locking block 312 is provided between the first keel 31 and the adjusting rod 22. The first locking block 312 has a third shaft groove 3121, and the first connecting shaft 2211 is inserted into the third groove. A second locking block 322 is provided between the second keel 32 and the adjusting rod 22. The second locking block 322 has a fourth shaft groove 3221, and the second connecting shaft 2221 is inserted into the fourth shaft groove 3221. The first locking block 312 and the second locking block 322 serve as intermediate connecting parts, enhancing the connection strength between the second keel 30 and the adjusting rod 22. The first locking block 312 cooperates with the first connecting shaft 2211 through the third shaft groove 3121, allowing the extension, retraction, and rotation of the first keel 31 to be transmitted to the adjusting rod 22. The second locking block 322 cooperates with the second connecting shaft 2221 through the fourth shaft groove 3221, enabling the minor angle adjustment of the second keel 32. This design distributes the external force originally borne directly by the secondary keel 30 to the locking blocks, reducing wear on the connecting shaft and shaft groove. The presence of the locking blocks also increases the redundancy of the adjustment system; if one connection point becomes loose, the other locking block can still maintain structural stability. In actual installation, the main keel 10, adjusting seat 21, and adjusting 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 adjusting rod 22 extend outside the main keel 10, preparing for the installation of subsequent components. According to actual construction needs, the first locking block 312 and the second locking block 322 are then installed between the adjusting rod 22 and the first keel 31 and the second keel 32, respectively. The third shaft groove 3121 on the first locking block 312 is precisely matched with the first connecting shaft 2211. During installation, the third shaft groove 3121 of the first locking block 312 is aligned with the first connecting shaft 2211 and then inserted, so that the first locking 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 locking block 312 through its own first shaft groove 3111, realizing the connection between the first keel 31 and the adjusting rod 22. Similarly, the fourth shaft groove 3221 of the second locking block 322 engages with the second connecting shaft 2221, and the second shaft groove 3211 of the second keel 32 cooperates with the second locking block 322, completing the connection between the second keel 32 and the adjusting rod 22. At this point, the retrofitted locking block, acting as an intermediate transition component, not only strengthens the connection between the secondary keel 30 and the adjusting rod 22, but also ensures the precise positioning relationship where the first shaft groove 3111 is parallel to the adjusting rod 22 and the second shaft groove 3211 is perpendicular to the adjusting rod 22. This allows the primary keel 31 to be extended and retracted along the adjusting rod 22, and the secondary keel 32 to achieve minute angle adjustments. Furthermore, in subsequent use, if adjustments to the keel angle and position are required, these can be flexibly achieved by disassembling and reinstalling the locking block, or by adjusting the position of the locking block on the connecting shaft.

[0051] The first locking block 312 is positioned between the first keel 31 and the adjusting rod 22. Its third shaft groove 3121 is tightly engaged with the first connecting shaft 2211 and also engages with the first shaft groove 3111 of the first keel 31. After adjustment, the first locking block 312 forms a dual radial and axial constraint on the first connecting shaft 2211 through the third shaft groove 3121, evenly transmitting the external force received by the first keel 31 after its extension and retraction adjustment to the adjusting rod 22 and the main keel 10, preventing loosening of the connection due to uneven force. Similarly, the fourth shaft groove 3221 on the second locking block 322 precisely matches the second connecting shaft 2221 and engages with the second shaft groove 3211 of the second keel 32. After the second keel 32 completes a small angle adjustment, the second locking block 322 restricts the displacement of the second connecting shaft 2221 in the vertical plane, stably maintaining the angle of the second keel 32 and preventing it from rotating or shifting due to vibration, external impact, or other factors during use. The locking mechanism effectively solves the problem of loosening of the keel structure after adjustment. Whether due to frequent operations during construction or external forces such as daily vibrations and wind loads during building use, the locking mechanism can stably fix 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 damage caused by structural instability. The locking mechanism reduces loosening and wear at the connection points, and significantly reduces wear on components such as the adjusting rod 22, connecting shaft, and shaft groove during long-term use. This allows the keel structure to maintain good performance even 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 this utility model, one of the first locking block 312 and the second locking block 322 is a rigid locking block, and the other is a flexible locking block. Preferably, the first locking block 312 is a rigid locking block, and the second locking block 322 is a flexible locking block. The difference in material properties between the first locking block 312 and the second locking block 322 forms a stable structure that combines rigidity and flexibility. When the first locking block 312 is a rigid locking block, it can be made of metal or high-strength engineering plastic, which has good resistance to deformation. After the rigid locking 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 first telescopic adjustment of the keel 31, effectively resisting axial displacement and radial sway caused by load changes. The rigid locking block directly transmits external force to the main keel 10, ensuring that the position remains stable after telescopic adjustment. The second locking block 322, as a flexible locking block, can be made of elastic rubber or composite materials, which has a certain elastic deformation capability. After the second keel 32 completes the micro-angle adjustment, the flexible locking block, through the cooperation of the fourth shaft groove 3221 and the second connecting shaft 2221, can both limit the excessive rotation of the connecting shaft and absorb the stress caused by factors such as vibration and temperature changes through its own elastic deformation. The elastic characteristics of the flexible locking block can also compensate for manufacturing tolerances and installation errors, ensuring the tightness and stability of the connection. The first locking block 312, as a rigid locking block, when the first keel 31 is adjusted for extension and retraction, the third shaft groove 3121 on the first locking block 312 is tightly engaged with the first connecting shaft 2211 of the adjusting rod 22. Due to its rigidity, it can firmly limit the axial movement of the first connecting shaft 2211, preventing the first keel 31 from falling off the adjusting rod 22 during the extension and retraction process. The rigid locking block evenly transmits the external force generated by the extension and retraction adjustment to the main keel 10, ensuring the stability and reliability of the extension and retraction adjustment. The second locking block 322 acts as a flexible locking block. When the second keel 32 undergoes a slight angle adjustment, the fourth shaft groove 3221 on the second locking block 322 engages with the second connecting shaft 2221 of the adjusting rod 22. The elasticity of the flexible locking block allows the second connecting shaft 2221 to rotate to a certain extent within the fourth shaft groove 3221, thereby achieving an angle change of the second keel 32 relative to the adjusting rod 22. During rotation, the flexible locking block absorbs and buffers external forces, preventing damage to the connection parts due to excessive rigidity, while ensuring the flexibility and smoothness of angle adjustment. In the entire keel structure, the rigid first locking block 312 and the flexible second locking block 322 cooperate with each other. The rigid locking block ensures the stability of the structure during telescopic adjustment, while the flexible locking block provides the freedom of angle adjustment. This allows the keel system to meet the stability requirements of telescopic adjustment while also enabling flexible multi-angle adjustments to adapt to different architectural design and construction requirements.

[0053] In environments with significant temperature variations, the combination of rigid and flexible clamping blocks effectively addresses issues arising from material expansion and contraction. Rigid clamps maintain the basic shape and dimensional accuracy of the structure, while flexible clamps compensate for dimensional differences caused by temperature changes through elastic expansion and contraction, preventing structural deformation or loosening of connections due to thermal stress and ensuring the stability of the keel system under varying temperature conditions. Simultaneously, the elastic properties of the flexible clamps effectively suppress vibration transmission caused by foot traffic and equipment operation, reducing noise levels within the building. In venues with high acoustic requirements, such as concert halls and conference rooms, this combination of rigid and flexible clamping blocks enhances the acoustic quality of the space and improves the user experience.

[0054] As a further improvement of this utility model, the adjusting seat 21 includes an adjusting plate 211, a U-shaped rotating seat 212 disposed on the adjusting plate 211, and a rotating shaft 213 passing through the rotating seat; the adjusting rod 22 is disposed inside the U-shaped rotating seat 212, and the rotating shaft 213 passes through the adjusting rod 22 to allow the adjusting rod 22 to rotate around the rotating shaft 213. By setting the adjusting plate 211 as a basic supporting component, an installation plane is provided for the entire adjusting seat 21. At the same time, the height can be adjusted by adjusting the thickness of the adjusting plate 211. The U-shaped rotating seat 212 is vertically disposed on the adjusting plate 211, and its U-shaped opening design provides installation space for the adjusting rod 22, allowing the adjusting rod 22 to be smoothly placed inside the U-shaped rotating seat. The rotating shaft 213 passes through the two side walls of the U-shaped rotating seat and the adjusting rod 22, forming a rotating shaft core. When the angle of the secondary keel 30 relative to the main keel 10 needs to be adjusted, an external force is applied to the adjusting rod 22, causing it to rotate around the shaft 213 within the U-shaped rotating seat. Since the shaft 213 passes through the adjusting rod 22, and the U-shaped rotating seat restricts the radial movement of the adjusting rod 22, the adjusting rod 22 can only rotate around the shaft 213, thus achieving precise angle adjustment. During rotation, the adjusting seat 21 provides stable support, ensuring smooth and controllable rotation of the adjusting rod 22. Combined with the shaft groove and connecting shaft, this allows for the extension, retraction, and pitch angle adjustment of the secondary keel 30, enabling flexible multi-angle adjustment of the keel in three-dimensional space.

[0055] As a further improvement of this utility model, the adjusting rod 22 is vertically arranged with the main keel 10. The adjusting rod 22 and the main keel 10 are arranged at a 90° angle to form a T-shaped frame basic structure. The torque generated when the adjusting rod 22 rotates is directly converted into the in-plane overturning moment of the secondary keel 30, avoiding energy loss caused by oblique force transmission. The internal adjusting seat 21 of the main keel 10 serves as a fixed fulcrum, and the adjusting rod 22 rotates around its axis. The operating torque is amplified through the lever effect of the vertical rod body, realizing lightweight operation of large-angle adjustment of the secondary keel 30. The T-shaped structure gives the keel system better resistance to lateral forces. When subjected to horizontal wind or seismic forces, the vertically arranged adjusting rod 22 and the main keel 10 form a stable frame structure, which can effectively disperse and resist lateral loads, reduce structural deformation, and improve the safety of the building. The vertically arranged adjusting rod 22 provides construction personnel with a clear installation benchmark, facilitating quick positioning and calibration. When working at heights, the vertical relationship between the adjusting rod 22 and the main keel 10 can be used to quickly determine whether the installation angle is correct, reduce measurement errors, and improve construction efficiency.

[0056] This utility model also provides an irregularly shaped skylight; please refer to [link / reference]. Figure 4 The system includes the aforementioned adjustable keel 1, a mounting body 2, and a glass panel 3. The adjusting plate 211 is connected to a mounting shaft 2111, which passes through the mounting body 2 to connect the adjusting seat 21 to the mounting body 2. The glass panel 3 is connected to the main keel 10 and the secondary keel 30. The mounting body 2, as the static base of the skylight, is typically fixed to the building structure, such as a roof steel beam or concrete ring beam. It has pre-set shaft holes or slide rails to accommodate the mounting shaft 2111. The adjusting plate 211 forms a movable connection with the mounting body 2 via the mounting shaft, allowing the entire adjustable keel 1 system to be finely adjusted in height relative to the building structure to compensate for construction errors. The glass panel 3 is bonded to the main and secondary keels 30 via flexible adhesive pads. Its own weight and wind load are transmitted through the keel to the adjusting seat 21, and finally distributed to the mounting body 2 by the mounting shaft. The angle of the secondary keel 30° is controlled by adjusting rod 22, forming a continuous variable curved surface with multiple glass panels 3 through cold bending, such as hyperbolic paraboloids and spiral shapes. This breaks through the limitations of traditional skylights with a single plane or fixed arc shape, adapting to parametric building facades. Elastic sealing strips are pre-installed at the joints of the glass panels 3, automatically expanding and contracting with changes in the keel angle to maintain the airtightness and watertightness 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 aesthetic and functional needs of 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, wood, ceramics, acrylic, a greening panel, a smart dimming panel, etc. In practical applications, the appropriate material can be selected according to actual needs, and this utility model does not impose any restrictions on it.

[0058] As a further improvement of this utility model, a decorative profile 33 is provided on the outside of the secondary keel 30, and a waterproof material 34 is provided at the connection between the decorative profile 33 and the main keel 10. The connection between the decorative profile 33 and the external part of the secondary keel 30 enhances the aesthetic effect of the skylight and effectively guides rainwater to the drainage system. The internal cavity of the decorative profile 33 can accommodate pipelines, realizing additional functions such as sunshade and ventilation. The waterproof material 34 is provided at the connection between the main keel 10 and the decorative profile 33. The waterproof material fills the connection gap through pre-compression deformation, forming a continuous waterproof barrier. When the main keel 10 undergoes slight deformation due to temperature changes or structural loads, the flexible waterproof material can maintain its sealing performance through its own elastic deformation. The diverse designs of the decorative profile 33 can be coordinated and unified with the overall architectural style, enhancing the aesthetic value of the building. At the same time, the internal cavity of the profile can integrate functional modules such as sunshade louvers and LED light strips, realizing an integrated design of decoration and function, and improving space utilization. The combination of decorative profile 33 and waterproof material 34 can form a certain acoustic barrier, effectively blocking external noise from entering the room. In busy or noisy environments, this design can significantly improve the indoor acoustic environment and enhance the user experience.
