Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel technology, specifically a hyperbolic aluminum single-panel. Background Technology

[0002] In the field of aluminum single-panel technology, hyperbolic aluminum single-panel is an aluminum decorative and enclosure component with a two-way curved surface formed by specific processes. It is widely used in modern building curtain walls, irregular ceilings, landscape designs and other scenarios. Its core feature is that by adjusting the curvature of the cross section of the curved surface, it can be adapted to the streamlined or irregular appearance design of different buildings, meet the personalized aesthetic and functional needs of buildings, and is an important component for realizing the diversification and irregularity of building appearance.

[0003] However, the hyperbolic aluminum panels currently on the market still have some defects in actual installation and use: most existing hyperbolic aluminum panels adopt a single independent installation mode, that is, each aluminum panel is connected to the external support frame of the building separately through fasteners, and there is no special splicing connection structure between adjacent aluminum panels. This installation method presents two major problems: First, the installation process is cumbersome and inefficient. Since each aluminum panel needs to be individually aligned and positioned with the supporting frame, especially in large-area building curtain walls or complex irregular ceiling installation scenarios, operators need to adjust the positional accuracy of each aluminum panel one by one. This not only increases the difficulty and workload of positioning but also significantly prolongs the on-site installation time, seriously affecting construction efficiency. Second, the safety is insufficient. Because there is no stable structure connecting the individual aluminum panels, they rely only on single or multiple points of fixation to the supporting frame. During long-term use, the connection between the aluminum panel and the supporting frame is prone to loosening due to external factors such as wind pressure, vibration, and temperature changes. Once the fixing structure of an individual aluminum panel fails, it is very easy for it to fall off. If applied to the exterior walls of high-rise buildings, the falling aluminum panels will become falling objects, posing a serious risk of injury or damage to pedestrians, vehicles, and ground facilities below, thus creating a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a hyperbolic aluminum single panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hyperbolic aluminum panel, comprising:

[0007] The curved surface and edge portion, the cross section of the curved surface can be set with different curvatures according to the usage requirements, so that the hyperbolic aluminum single panel can adapt to the diverse shape requirements of different building appearances or installation scenarios.

[0008] The curved surface has integrally formed edge portions on both sides along its hyperbolic contour. The overall shape of the edge portions matches the hyperbolic contour of the curved surface. The surface of the edge portions is smooth and the cross-section is rectangular, ensuring structural coordination with the curved surface and facilitating the docking operation and subsequent installation and fixing of adjacent hyperbolic aluminum panels. The front and rear ends of the edge portions are respectively provided with matching front and rear docking components, and the sides of the two edge portions are respectively provided with matching left and right docking components. The front and rear docking components can realize the splicing of adjacent hyperbolic aluminum panels in the front-to-back direction, and the left and right docking components can realize the splicing of adjacent hyperbolic aluminum panels in the left and right direction. This makes the splicing and installation of multiple hyperbolic aluminum panels more convenient and enhances the connection stability between adjacent panels, effectively preventing adjacent hyperbolic aluminum panels from falling off during later use.

[0009] Preferably, the front and rear docking components include a docking block and a docking groove. The docking block is integrally formed with the front end face of the edge portion, and the docking groove is disposed on the rear end face of the edge portion. The external dimensions of the docking block are adapted to the internal cavity dimensions of the docking groove, so that the docking block of the edge portion of one hyperboloid aluminum panel can be inserted into the docking groove of the edge portion of another hyperboloid aluminum panel to achieve preliminary positioning in the front and rear directions.

[0010] Preferably, the side of the mating block is provided with a threaded hole, and the edge part is provided with a through hole coaxial with the threaded hole on the outer side of the mating groove. A flat-head bolt can be inserted into the through hole, and the screw end of the flat-head bolt can form a threaded connection with the threaded hole. By tightening the flat-head bolt, the mating block can be fixed in the mating groove, thereby realizing a stable splicing of adjacent hyperboloid aluminum panels in the front and back directions.

[0011] Preferably, the left and right docking components include a receiving groove and a docking ring groove. The receiving groove is opened on the side of the left edge and is a rectangular groove with semi-circular ends. The inner walls of the two sides of the receiving groove are provided with strip-shaped sliding grooves along the length of the groove. The bottom left side of the receiving groove is provided with a slot in the vertical direction. The docking ring groove is opened on the side of the right edge and the position of the docking ring groove corresponds to the position of the receiving groove on the edge of the adjacent hyperboloid aluminum panel.

[0012] Preferably, the left and right docking assembly further includes a plug, which is a cylindrical structure. Its outer diameter is adapted to the inner diameter of the slot and the inner diameter of the docking ring groove. The top center of the plug has a hollow cavity along the axial direction. The bottom of the plug can be inserted into the slot at the bottom of the receiving groove. The bottom of the plug and the slot are interference-fitted to prevent the plug from loosening and falling off. When adjacent hyperboloid aluminum panels are docked left and right, the top of the plug can be inserted into the docking ring groove at the edge of another hyperboloid aluminum panel. The top of the plug and the docking ring groove are interference-fitted. Through the double interference fit of the plug, the slot, and the docking ring groove, the structural stability of the left and right docking of adjacent hyperboloid aluminum panels is improved.

[0013] Preferably, a sliding plate can be installed in the receiving groove. The sliding plate is a rectangular plate with semi-circular ends. The two sides of the sliding plate are integrally formed with raised sliding strips along the length direction. The cross-sectional dimensions of the sliding strips are adapted to the cross-sectional dimensions of the sliding grooves on the inner wall of the receiving groove, so that the sliding strips can be embedded in the sliding grooves and slide along the length direction of the sliding grooves, thereby driving the sliding plate to slide back and forth in the receiving groove. When it is not necessary to insert the insert, the sliding plate can cover the slot at the bottom of the receiving groove to prevent external dust and impurities from entering the slot and causing blockage. The upper end surface of the sliding plate has multiple anti-slip grooves along the length direction to increase the friction between the hand and the surface of the sliding plate, making it easier for the operator to push the sliding plate. The height of the sliding plate is consistent with the height of the groove opening of the receiving groove, ensuring that the sliding plate does not protrude from the edge surface when it is fully stored in the receiving groove, ensuring the smoothness of the edge surface.

[0014] Preferably, the bottom of the edge portion is integrally formed with a mounting plate along the length direction. The mounting plate is a horizontally arranged rectangular flat plate structure. Multiple mounting holes are evenly opened along the length direction on the mounting plate. The mounting holes are circular through holes. By inserting bolts, rivets and other fasteners into the mounting holes, the hyperbolic aluminum panel can be fixed to the external support frame or wall of the building, further improving the stability of the hyperbolic aluminum panel after installation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention strengthens the connection at the joint of adjacent aluminum panels by setting up mutually matching docking components, and by using the embedded fit of the docking block and the docking groove, the interference fit of the insert post and the slot and the docking ring groove. Moreover, the splicing operation does not require complicated tools, and can be completed simply by inserting the docking block, inserting the bolt and tightening it, or inserting the insert post, making the installation convenient and efficient. At the same time, the stable splicing structure can effectively resist external forces such as vibration and wind pressure during later use, prevent individual aluminum panels from falling off, and improve the safety of use.

[0017] This invention features an edge portion integrally formed along the double-curved contour of the curved surface with a rectangular cross-section. This integral forming process directly enhances the connection strength between the edge portion and the curved surface, avoiding structural weaknesses caused by separate assembly and extending the service life of the aluminum panel. At the same time, the rectangular cross-section provides a regular docking and installation space, and the smooth surface reduces splicing obstacles. This facilitates the precise assembly of docking components and allows adjacent aluminum panels to form a tightly fitting contact surface when spliced, further ensuring splicing stability.

[0018] This invention features a sliding plate inside the receiving groove. When the insertion post is not required, the sliding plate can completely cover the slot at the bottom of the receiving groove, effectively preventing external dust, impurities, and rainwater from entering the slot and causing blockage or corrosion, thus ensuring the cleanliness and compatibility of the slot during subsequent assembly.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1 to 7 This utility model provides a technical solution:

[0031] A hyperbolic aluminum panel includes a curved section 1 and an edge section 2. The curvature of the cross section of the curved section 1 can be flexibly adjusted. Different cross section curvature parameters can be flexibly set according to actual architectural design requirements, such as adapting to the large curvature of curved building curtain walls, the small curvature of irregular ceilings, or the gradual curvature of complex curved surface shapes, thereby meeting the adaptation requirements of diverse architectural appearances and installation scenarios and ensuring that the aluminum panel is highly consistent with the overall architectural style.

[0032] Edge portion 2 is integrally formed along the hyperbolic contour of curved surface portion 1. The overall shape of edge portion 2 perfectly matches the hyperbolic contour of curved surface portion 1, avoiding structural misalignment or abrupt connections and ensuring the smoothness and structural coordination of the overall appearance of the hyperbolic aluminum panel. On the other hand, the surface of edge portion 2 is smooth, and the cross-section is a standard rectangular structure. The smooth surface reduces obstacles during docking, while the rectangular cross-section provides a regular installation and docking space, which facilitates the precise assembly of subsequent docking components and allows adjacent aluminum panels to form a tight contact surface when spliced. At the same time, the integral molding process also improves the connection strength between edge portion 2 and curved surface portion 1, avoiding structural weaknesses caused by separate assembly and extending the service life of the aluminum panel.

[0033] Edge 2 serves as the area for splicing, with matching front and rear mating components and left and right mating components installed at its front and rear ends and on its two sides, respectively. These two types of components enable the splicing of aluminum panels in the front-to-back and left-to-right directions.

[0034] like Figure 4 As shown, the front and rear docking assembly consists of docking block 3 and docking groove 4. The docking block 3 is integrally formed with the front end face of the edge part 2, and its structural shape matches the rectangular cross-section of the edge part 2, forming a regular block structure. The docking groove 4 is correspondingly opened on the rear end face of the edge part 2. The internal cavity dimensions (including length, width, and depth) of the groove are adapted to the external dimensions of the docking block 3. When two adjacent hyperboloid aluminum panels are spliced ​​front and rear, the docking block 3 of the edge part 2 of the previous aluminum panel can be completely inserted into the docking groove 4 of the edge part 2 of the next aluminum panel. Through embedded cooperation, the initial positioning in the front and rear direction can be quickly achieved, avoiding left and right offset or up and down misalignment during splicing.

[0035] In this embodiment, to improve the stability of the front and rear splicing, the side of the mating block 3 is provided with a threaded hole 301 along the horizontal direction, and the outer side of the edge portion 2 corresponding to the mating groove 4 is provided with a through hole coaxial with the threaded hole 301. The diameter of the through hole is adapted to the diameter of the flat-head bolt 5, ensuring that the bolt can be smoothly inserted. After the mating block 3 is inserted into the mating groove 4, the flat-head bolt 5 is inserted through the through hole, so that the end of the bolt forms a threaded connection with the threaded hole 301 of the mating block 3. After tightening the bolt, the mating block 3 can be firmly fixed in the mating groove 4, completely restricting the displacement of adjacent aluminum panels in the front and rear direction, realizing a stable splicing in the front and rear direction, and avoiding splicing loosening caused by vibration, wind pressure and other factors during later use.

[0036] like Figure 5 and Figure 7 As shown, the left and right docking components consist of a receiving groove 8, a docking ring groove 9, and a plug 6. The receiving groove 8 is located on the side of the left edge portion 2 and is a rectangular groove with semi-circular ends. Its width can accommodate the sliding plate 7 and the plug 6. The inner walls of both sides of the receiving groove 8 have strip-shaped sliding grooves 801 along the length of the groove to guide the sliding of the sliding plate 7. A circular slot 802 is located vertically at the bottom left side of the receiving groove 8. The diameter of the slot 802 is adapted to the outer diameter of the plug 6. The docking ring groove 9 is located on the side of the right edge portion 2. Its position corresponds exactly to the receiving groove 8 of the adjacent hyperboloid aluminum single panel edge portion 2. The inner diameter of the groove is the same as the inner diameter of the slot 802, and its depth is adapted to the length of the top of the plug 6, providing precise docking space for the insertion of the plug 6.

[0037] In this embodiment, the insert 6 adopts a cylindrical structure, and its outer diameter is strictly matched with the inner diameter of the slot 802 and the inner diameter of the mating ring groove 9 to ensure a tight fit after insertion. The top center of the insert 6 has a hollow cavity along the axial direction, which reduces the weight of the insert 6 itself while ensuring the structural strength of the insert 6 and avoids the increase in weight or material waste caused by solid design. When splicing left and right, the bottom of the insert 6 is first vertically inserted into the slot 802 at the bottom of the receiving groove 8. The two adopt an interference fit, which not only facilitates the manual insertion of the insert 6, but also ensures that the insert 6 will not loosen or fall off after insertion, thus achieving initial fixation. Then, the right edge 2 of the adjacent aluminum single panel is brought close together, so that the top of the insert 6 is inserted into the mating ring groove 9 of the edge 2 of the other aluminum single panel. The top of the insert 6 and the mating ring groove 9 also adopt an interference fit. Through the double interference fit, a connection in the left and right direction is formed, which effectively restricts the left and right displacement and up and down sway of the adjacent aluminum single panels and greatly improves the structural stability of the left and right splicing.

[0038] It should be noted that the slide plate 7 is a semi-circular rectangular plate with both ends that matches the shape and size of the receiving groove 8. Both sides have integrally formed raised sliding strips 701 along their length. The cross-sectional dimensions of the sliding strips 701 precisely match the cross-sectional dimensions of the sliding groove 801 on the inner wall of the receiving groove 8. The gap between the sliding strips 701 and the sliding groove 801 is preferably controlled within the range of 0.1 to 0.2 mm to ensure that the slide plate 7 can slide smoothly along the length of the sliding groove 801. Multiple parallel strip-shaped anti-slip grooves 702 are formed on the upper surface of the slide plate 7 along its length, which increases the friction between the hand and the surface of the slide plate 7, making it easier for operators to quickly push the slide plate 7 during installation (especially when operating while wearing gloves). In addition, the height of the sliding plate 7 is exactly the same as the height of the groove of the receiving groove 8. When the sliding plate 7 is completely stored in the receiving groove 8, its surface is flush with the surface of the edge part 2, without any protruding structure, ensuring the overall smoothness of the surface of the edge part 2. When the insertion post 6 is not required (such as when the aluminum single panel is stored separately or during temporary installation), the sliding plate 7 can completely cover the slot 802 at the bottom of the receiving groove 8, preventing external dust, impurities, rainwater, etc. from entering the slot 802 and causing blockage or corrosion, ensuring the cleanliness and compatibility of the slot 802 during subsequent splicing.

[0039] Example 2:

[0040] Please see Figure 8 This utility model also provides a technical solution that is basically the same as that in Embodiment 1, with slight differences:

[0041] like Figure 8 The bottom of the edge portion 2 is integrally formed with a mounting plate 10 along its length. The mounting plate 10 adopts a horizontally set rectangular flat plate structure, and its length is exactly the same as the length of the edge portion 2, ensuring that the mounting plate 10 can evenly bear the weight of the aluminum single panel. Multiple circular through holes are evenly opened on the mounting plate 10 along its length as mounting holes 1001. The diameter of the mounting holes 1001 is designed according to the specifications of common fasteners (such as bolts and rivets), and the hole spacing is set according to the spacing of commonly used support frames in the construction industry (such as 600mm and 800mm), which facilitates quick alignment with the support frame during installation. During actual installation, operators can use bolts, rivets, and other fasteners to pass through the mounting holes 1001 and fix the hyperbolic aluminum panel to the external support frame or wall of the building. The mounting plate 10 can evenly distribute the weight of the aluminum panel onto the support structure, avoiding deformation or detachment caused by direct stress on the aluminum panel, and further improving the overall stability of the hyperbolic aluminum panel after installation. At the same time, the one-piece molded mounting plate 10 eliminates the need for subsequent assembly steps, shortens on-site installation time, and improves construction efficiency.

[0042] It should be noted that, to further enhance the connection stability between the mounting plate 10 and the building support structure, corner brackets can be added at the junction of the mounting plate 10 and the edge 2. The corner brackets are made of metal material suitable for the thickness of the mounting plate 10 (such as aluminum alloy corner brackets). One side is fixed to the side or bottom of the mounting plate 10 with bolts, while the other side is attached and securely fastened to the external building support frame. This effectively disperses the localized stress on the mounting plate 10, preventing deformation or loosening of the mounting plate 10 due to vibration, wind pressure, or other factors during long-term use.

[0043] In general, when using this utility model, the mounting plate 10 of the hyperbolic aluminum panel is first aligned and tightened with the external support frame of the building through the mounting holes 1001 on it using bolts or rivets and other fasteners. Then, adjacent aluminum panels are spliced. When splicing in the front-to-back direction, the mating block 3 of the edge 2 of the previous aluminum panel is inserted into the mating groove 4 of the next panel, and then the flat-head bolt 5 is inserted through the through hole and tightened with the threaded hole 301 of the mating block 3. When splicing in the left-to-right direction, the sliding plate 7 in the receiving groove 8 of the left edge 2 is slid to expose the slot 802, the bottom of the insert 6 is inserted into the slot 802 with an interference fit, and then the mating ring groove 9 of the right edge 2 of the adjacent aluminum panel is mated with the top of the insert 6 with an interference fit. When no splicing is required, the sliding plate 7 can be slid to cover the slot 802.

[0044] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
