Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building curtain wall decoration materials, specifically to a pressure-resistant hyperbolic aluminum single panel. Background Technology
[0002] In the high-end construction sector, hyperbolic aluminum panels are highly favored for their elegant design, but their structural performance suffers from significant bottlenecks. Existing products often employ uniformly distributed ribs or simple honeycomb cores directly connected to thin panels. This traditional structure has inherent flaws when facing severe wind pressure and large-span applications: First, it lacks sufficient compressive and deformation resistance; unscientific force transmission paths easily lead to stress concentration, causing wind pressure deformation, flutter, and even fatigue failure, posing significant safety hazards. Second, to compensate for insufficient stiffness, excessive material is often used, resulting in excessive weight and high costs. Furthermore, the strength of the connection points between the reinforcing ribs and the thin panels is limited by the panel thickness, becoming a structural weak point. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a pressure-resistant hyperbolic aluminum single panel to solve the problems of insufficient pressure resistance, excessive weight and low connection reliability of the existing technology.
[0004] This utility model is achieved through the following technical solution: A pressure-resistant hyperboloid aluminum panel includes a decorative panel and a back panel. The inner side of the decorative panel has an integrally formed reinforcing frame, which consists of four narrow sides extending toward the back panel. A pressure-resistant structure is provided between the decorative panel and the back panel. The pressure-resistant structure includes main reinforcing ribs and auxiliary reinforcing ribs. The main reinforcing ribs extend along the length of the decorative panel and have first connecting portions at both ends, which are fixedly connected to the corresponding narrow sides of the reinforcing frame. Multiple auxiliary reinforcing ribs are provided on both sides of the main reinforcing ribs and extend obliquely. Each auxiliary reinforcing rib has a second connecting portion at both ends, which are fixedly connected to the adjacent narrow sides of the reinforcing frame and the sidewalls of the main reinforcing ribs, respectively. The main reinforcing ribs and the auxiliary reinforcing ribs are connected to form a spatial support frame. This frame and the reinforcing frame divide the cavity between the decorative panel and the back panel into multiple cells. Each cell is filled with a core material fixed therein. The back panel and the bottom surface of the core material are compositely connected by an adhesive material.
[0005] Preferably, the cross-sections of the main reinforcing rib and the auxiliary reinforcing rib are both U-shaped, and their side walls and bottom walls together constitute the first connecting part and the second connecting part.
[0006] Preferably, the first connecting part and the second connecting part are connected to the sidewall of the reinforcing frame and the main reinforcing rib by a hot-melt implantation method.
[0007] Preferably, the main reinforcing rib is a variable cross-section member, wherein the cross-sectional height of its central region is greater than the cross-sectional height of its two end regions.
[0008] Preferably, the core material is an aluminum honeycomb core, and the outer edge shape of the aluminum honeycomb core is adapted to the shape of the cell and fixed by an adhesive.
[0009] Preferably, the honeycomb cavities of the aluminum honeycomb core are filled with aluminum-based closed-cell foam material.
[0010] The beneficial effects of this utility model are as follows: This utility model constructs a biomimetic space support frame by setting main reinforcing ribs, auxiliary reinforcing ribs and reinforcing frame, which significantly improves rigidity and stability, effectively resists wind pressure deformation, and adopts U-shaped cross section and variable cross section design to achieve lightweight while ensuring strength; aluminum honeycomb core and aluminum-based closed-cell foam filling form a "rigid and flexible" composite system, which has the functions of impact resistance, vibration reduction and heat insulation.
[0011] This utility model completely eliminates the dependence on the thickness of the decorative panel itself by directly connecting the first and second connecting parts of the reinforcing rib to the sturdy reinforcing frame; the connection node changes from a connection with a "thin plate" to a connection with a "thick frame", which exponentially improves the strength and reliability of the connection point and solves a long-standing pain point in the industry.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0015] Please see Figure 1-4 This utility model provides a pressure-resistant hyperbolic aluminum single panel technical solution: a pressure-resistant hyperbolic aluminum single panel includes a decorative panel 1 and a back panel 2. The inner side of the decorative panel 1 is provided with an integrally formed reinforcing frame 11, which is composed of four narrow sides extending toward the back panel 2. A pressure-resistant structure is provided between the decorative panel 1 and the back panel 2. The pressure-resistant structure includes a main reinforcing rib 3 and an auxiliary reinforcing rib 4. The main reinforcing rib 3 extends along the length direction of the decorative panel 1, and its two ends are provided with first connecting parts 31. The first connecting parts 31 and the corresponding narrow sides of the reinforcing frame 11 are connected. The main reinforcing ribs 3 are fixedly connected at both ends; multiple auxiliary reinforcing ribs 4 are provided on both sides of the main reinforcing rib 3 and extend obliquely, with second connecting parts 41 at both ends. The second connecting parts 41 are fixedly connected to the adjacent narrow side of the reinforcing frame 11 and the side wall of the main reinforcing rib 3, respectively. The main reinforcing rib 3 and the auxiliary reinforcing ribs 4 are connected to form a spatial support frame. This frame and the reinforcing frame 11 divide the cavity between the decorative panel 1 and the back panel 2 into multiple cells. The cells are filled with core material 5 fixed inside. The back panel 2 and the bottom surface of the core material 5 are connected by adhesive. The decorative panel 1 and the back panel 2 form a basic box structure through the reinforcing frame 11. The main reinforcing rib 3, as the core load-bearing component, directly transfers the external load borne by the central area to the reinforcing frame 11 along the length direction. The auxiliary reinforcing ribs 4 connect the main reinforcing rib 3 and the reinforcing frame 11 in an oblique extension manner to form a spatial force transmission system, effectively distributing the local load to the overall structure. The space support frame divides the box into multiple cells, and a uniform support effect is obtained by filling the core layer material 5. Finally, a complete compression-resistant system is formed by bonding the back plate 2 with the core layer material 5.
[0016] Both the main stiffener 3 and the auxiliary stiffener 4 have U-shaped cross-sections, with their side walls and bottom wall forming the first connection part 31 and the second connection part 41. The U-shaped cross-section design of the main stiffener 3 and the auxiliary stiffener 4 utilizes their side walls and bottom wall to form a wide connection interface. This structure significantly improves the moment of inertia of the section, enhances bending stiffness, and provides ample construction space for connection operations, ensuring the continuity and reliability of force flow transmission between components.
[0017] The first connecting part 31 and the second connecting part 41 are connected to the sidewalls of the reinforcing frame 11 and the main reinforcing rib 3 by a hot-melt implantation method. The hot-melt implantation connection uses a high-temperature melting process to fuse the metal materials together at the connection interface, and after cooling, forms an internal thread structure with metallurgical bonding characteristics. This method can achieve connection performance close to the strength of the base material, avoids deformation problems caused by the heat-affected zone of welding, and is particularly suitable for hyperbolic panel connection scenarios with high shape accuracy requirements.
[0018] Main stiffener 3 is a variable cross-section member, with its central section height greater than that of its two ends. This variable cross-section design, with its increased central section height, matches the bending moment distribution characteristics, ensuring that the material distribution conforms to the principle of equal strength. This design effectively eliminates stress concentration while maintaining the structure's bending resistance, achieving a balance between lightweight design and high performance.
[0019] The core material 5 is an aluminum honeycomb core. The outer edge shape of the aluminum honeycomb core is adapted to the shape of the cell and fixed with adhesive. As the core material 5, the aluminum honeycomb core, with its anisotropic characteristics and highly ordered cell structure, provides excellent compressive strength in the vertical direction and exhibits good deformation stability in the shear direction. Fixed to the inner wall of the cell with adhesive, it forms a large number of micro-support units, significantly improving the panel's resistance to local buckling.
[0020] The honeycomb cavities of the aluminum honeycomb core are filled with aluminum-based closed-cell foam material 6. After the aluminum-based closed-cell foam material 6 fills the honeycomb cavities, it absorbs impact energy by utilizing the plastic deformation capacity of its pore structure and reduces vibration transmission through the energy dissipation mechanism inside the material. At the same time, the closed-cell structure forms a sealed air layer, further improving the overall thermal insulation performance.
[0021] Working principle: Before the aluminum panel is installed, the core components are prefabricated and adapted: For the aluminum honeycomb core (i.e., core material 5), aluminum honeycomb cores with matching outer edges are processed according to the cell shape of the "spatial support frame" between the decorative panel 1 and the back panel 2 to ensure complete embedding; aluminum-based closed-cell foam material 6 is filled into its honeycomb cavity, and the foam cell structure is used to pre-set the impact absorption and heat insulation foundation, and then it is pre-fixed to the inner wall of the cell with adhesive to form a micro support unit to improve the panel's resistance to local buckling. Entering the core structure assembly stage, the reinforcing ribs are connected first: the main reinforcing rib 3 is a variable cross-section component, with the middle section height greater than the two ends, placed along the length of the decorative panel 1, and the first connecting parts 31 at both ends (the side walls and bottom walls of the U-shaped section are combined) are connected to the corresponding narrow sides of the inner reinforcing frame 11 of the decorative panel (four narrow sides formed in one piece) through hot-melt implantation. Hot-melt implantation forms a metallurgical bond thread by fusing metal at high temperature, avoiding welding deformation and ensuring strength. Next, auxiliary reinforcing ribs 4 are installed, obliquely arranged on both sides of the main reinforcing ribs, and similarly heat-fused into place, so that the second connecting parts 41 at both ends (formed by the side walls and bottom walls of the U-shaped cross section) are respectively connected to the adjacent narrow side of the reinforcing frame 11 and the side wall of the main reinforcing rib 3. At this time, the main and auxiliary reinforcing ribs form a spatial support frame, and the cavity separating the decorative panel and the back panel from the reinforcing frame is divided into multiple cells. Subsequently, the composite back panel 2 is connected to the bottom surface of the core layer material 5 through adhesive material to form a complete basic box structure.
[0022] The assembled aluminum panels are hoisted to the designated location (such as building exterior walls, interior decorative surfaces, etc.) and fixed to the building structure via the reinforcing frame 11 to prevent displacement. During normal use, the aluminum panels bear external loads (such as wind force, their own weight, minor impacts, etc.), with each structure working in concert: the load is first applied to the decorative panel 1, which distributes the load to the reinforcing frame 11 and the spatial support frame; the central load is transferred to the main reinforcing rib 3, whose variable cross-section design matches the bending moment distribution, conforming to the principle of equal strength and avoiding stress concentration; local loads are transferred to the auxiliary reinforcing rib 4, which is distributed to the main reinforcing rib and the reinforcing frame through an inclined structure, forming a "local-overall" force transmission system; the aluminum honeycomb core within the cells, through its ordered cell structure, provides compressive strength in the vertical direction and maintains stability in the shear direction, preventing local buckling of the panel and back panel and assisting in load distribution.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
