Description

Technical Field

[0001] This utility model relates to the field of architectural decoration, and in particular to a composite curtain wall structure. Background Technology

[0002] Curtain walls, as an important component of modern architectural decoration, are widely used in interior and exterior decoration, primarily to enhance the aesthetics, functionality, and spatial partitioning of buildings. Curtain walls typically consist of panels and a supporting structure, installed on the surface of building walls. They not only serve a decorative purpose but also provide functions such as heat insulation, sound insulation, and fireproofing, while being easy to maintain and upgrade.

[0003] However, existing large curtain walls on the market typically use traditional wet-laying or direct bolt fixing methods, which are not only inefficient to construct but also susceptible to environmental humidity, leading to decreased bonding strength and even the risk of detachment. Furthermore, existing curtain wall panel structures often use solid panels or simple sandwich designs. While these meet basic strength requirements, solid structures consume more materials and are heavier, thus increasing the building load.

[0004] Therefore, it is necessary to provide a composite curtain wall structure that can effectively improve the convenience of disassembly and assembly, and avoid excessive weight of the panel structure. Utility Model Content

[0005] The purpose of this utility model is to provide a composite curtain wall structure that can effectively improve the convenience of disassembly and assembly, and avoid excessive weight of the panel structure.

[0006] According to one aspect of this application, a composite curtain wall structure is provided, installed on a wall, the composite curtain wall structure comprising:

[0007] The dry-hanging structure is embedded and fixed in the wall. The dry-hanging structure includes a hanging member that abuts against the wall. The side of the hanging member away from the wall has a number of fixing holes.

[0008] A honeycomb panel layer is fixedly connected to the hanging component. The honeycomb panel layer includes a honeycomb aluminum plate and a hook assembly fixedly connected to the honeycomb aluminum plate.

[0009] When viewed along a first direction perpendicular to the surface of the honeycomb aluminum panel, a plurality of honeycomb holes are formed on the honeycomb aluminum panel. The honeycomb holes penetrate the honeycomb aluminum panel along the first direction. When the hook assembly passes through the fixing hole and enters the hanger along the first direction, the honeycomb panel layer moves along a second direction parallel to the surface of the honeycomb aluminum panel. The hook assembly engages with the edge of the fixing hole to fix the honeycomb panel layer.

[0010] More preferably, the honeycomb panel layer further includes an adhesive layer, which is coated on the side of the honeycomb aluminum panel opposite to the dry-hanging structure.

[0011] More preferably, the honeycomb panel layer further includes a decorative layer, which is fixedly connected to the adhesive layer and located on the side of the adhesive layer opposite to the honeycomb aluminum panel.

[0012] More preferably, the hook assembly includes an upper hook and a lower hook. When viewed along a direction parallel to the surface of the honeycomb panel, the upper hook is fixedly connected to the honeycomb panel, and the lower hook is fixedly connected to the side of the honeycomb panel where the upper hook is located, and is located below the upper hook in the vertical direction.

[0013] More preferably, the upper hook and the lower hook form a snap-fit ​​space in the vertically downward direction. When the honeycomb aluminum plate passes through the fixing hole and moves in the second direction, the edge of the fixing hole snaps into the snap-fit ​​space to fix the honeycomb aluminum plate.

[0014] More preferably, when viewed along the first direction, the honeycomb holes are hexagonal in shape, and the side length of any side of any honeycomb hole in the honeycomb aluminum plate is the same as the side length of any other side of the honeycomb hole.

[0015] More preferably, the included angle between any edge of the honeycomb cell and any adjacent edge connected to it is denoted as R, and satisfies the relationship: R = 120°.

[0016] More preferably, the first direction is perpendicular to the second direction.

[0017] More preferably, the dry-hanging structure further includes:

[0018] Anchors are inserted into the wall along the first direction and pre-embedded and fixed in the wall.

[0019] The hook is fixedly connected to the anchor.

[0020] More preferably, the decorative layer is made of one or more of the following materials: aluminum alloy, bio-based resin, photocatalytic self-cleaning glass, stone, polycarbonate, epoxy resin, stainless steel, or ceramic.

[0021] This utility model has the following beneficial effects:

[0022] The hook assembly passes through the fixing hole along the first direction and enters the hanging component. The hook assembly also engages with the edge of the fixing hole along the second direction, allowing the honeycomb aluminum panel to be quickly fixed to the dry-hanging structure through movement in two directions. This effectively improves the convenience of assembly and disassembly. Furthermore, the design of the honeycomb aluminum panel with a plurality of honeycomb holes inside the honeycomb panel layer, with each honeycomb hole penetrating the honeycomb aluminum panel along the first direction, results in a large central control area in the honeycomb aluminum panel, preventing the honeycomb panel layer from being too heavy.

[0036] Please refer to Figure 1 - Figure 8 One embodiment of this application provides a composite curtain wall structure 100, which is installed on a wall 200. The composite curtain wall structure 100 includes: a dry-hanging structure 10 and a honeycomb panel layer 20.

[0037] The dry-hanging structure 10 is fixed to the wall 200. The dry-hanging structure 10 includes a hook member 11 that abuts against the wall 200. The hook member 11 has a plurality of fixing holes 11A on the side away from the wall 200. The honeycomb panel layer 20 is fixedly connected to the hook member 11. The honeycomb panel layer 20 includes a honeycomb aluminum plate 21 and a hook assembly 22 fixedly connected to the honeycomb aluminum plate 21. When viewed along a first direction F1 perpendicular to the surface of the honeycomb aluminum plate 21, a plurality of honeycomb holes 21A are formed on the honeycomb aluminum plate 21. The honeycomb holes 21A penetrate the honeycomb aluminum plate 21 along the first direction F1. When the hook assembly 22 passes through the fixing holes 11A and enters the hook member 11 along the first direction F1, the honeycomb panel layer 20 moves along a second direction F2 parallel to the surface of the honeycomb aluminum plate 21. The hook assembly 22 engages with the edge of the fixing holes 11A to fix the honeycomb panel layer 20.

[0038] This structure employs a mechanical snap-fit ​​method between the pre-embedded hanger 11 and the honeycomb panel hook assembly 22, solving the problem of low installation efficiency in traditional curtain walls. The hanger 11 is pre-embedded in the wall 200, with fixing holes 11A on its surface, forming a dual-motion mechanism with the hook assembly 22 on the back of the honeycomb aluminum panel 21, which is horizontally inserted and then vertically snapped. During installation, the installer first inserts the anchor 12 in the dry-hanging structure 10 horizontally into the wall 200 and pre-embeds it within the wall 200. At this time, the hanger 11 of the dry-hanging structure 10 abuts against the wall 200 in the horizontal direction. Next, the installer aligns the hook assembly 22 on the honeycomb panel layer 20 with the fixing holes 11A on the hanger 11, and pushes the hook assembly 22 through the fixing holes 11A in the horizontal direction into the internal space of the hanger 11. At this time, the honeycomb aluminum panel 21 abuts against the outer side of the hanger 11. The installers then move the honeycomb panel 20 vertically downwards, allowing the lower edge of the fixing hole 11A to engage with the hook space 25 formed by the hooks in the hook assembly 22, achieving both vertical unidirectional and horizontal bidirectional fixation. This installation method replaces the bolt fixing after drilling, enabling very quick assembly and disassembly of the honeycomb panel 20, improving the installation convenience of the composite curtain wall structure 100, and making it very convenient to replace the honeycomb panel 20 later, suitable for large-area curtain wall construction. In addition, the design of multiple honeycomb holes 21A on the honeycomb aluminum panel 21 in the honeycomb panel 20 significantly reduces the overall weight of the honeycomb panel 20. Each honeycomb hole 21A is a regular hexagon with equal side lengths. The reason why the honeycomb hole 21A structure can significantly improve structural rigidity within a limited contact area is mainly due to its unique geometric structure and mechanical principles. This structure, through biomimetic design, redistributes the aluminum panel into a regular honeycomb arrangement, achieving rigidity exceeding that of solid panels while reducing weight. From a mechanical perspective, the honeycomb structure 21A concentrates the aluminum plate structure in the most effective direction of force application. When the honeycomb plate is subjected to a vertical external force, the force is transmitted axially along the honeycomb holes 21A through the hole walls, forming an efficient force flow path. Each honeycomb hole 21A in the honeycomb aluminum plate 21 acts as a support unit, forming a dense load-bearing network on the surface of the honeycomb aluminum plate 21. Under the same surface contact area and the same pressure, the support performance of the honeycomb aluminum plate 21 is significantly better than that of a solid aluminum plate, while the hollow structure of the honeycomb aluminum plate 21 significantly reduces the mass of the aluminum plate, avoiding excessive material consumption due to excessive weight and excessive load on the wall 200.

[0039] More preferably, the honeycomb panel layer 20 further includes an adhesive layer 23, which is coated on the side of the honeycomb aluminum panel 21 opposite to the dry-hanging structure 10.

[0040] The adhesive layer 23, made of adhesive, primarily serves as a physical connection between the honeycomb aluminum panel 21 and the decorative layer 24. Secondly, the adhesive layer 23 also acts as a stress buffer. Due to the difference in thermal expansion coefficients between the materials of the honeycomb aluminum panel 21 and the decorative layer 24, the two materials will undergo varying degrees of microscopic expansion and contraction under conditions of large diurnal temperature variations or seasonal changes. In this case, the adhesive in the adhesive layer 23, using polyurethane or silicone adhesives with appropriate elasticity, can effectively absorb this differential deformation, preventing structural cracking or delamination of the decorative layer 24 due to accumulated thermal stress. Furthermore, the adhesive layer 23, through its full contact area with both the decorative layer 24 and the honeycomb aluminum panel 21, makes the overall structure a synergistically stressed composite, improving structural load-bearing capacity.

[0041] More preferably, the honeycomb panel layer 20 further includes a decorative layer 24, which is fixedly connected to the adhesive layer 23 and located on the side of the adhesive layer 23 opposite to the honeycomb aluminum panel 21.

[0042] The decorative layer 24, as the outermost visual interface of the composite curtain wall structure 100, directly determines the aesthetic effect of the interior building facade. By fixing the decorative layer 24 to the honeycomb aluminum panel 21 through the adhesive layer 23, various materials of the decorative layer 24 and the honeycomb aluminum panel 21 can be combined to form various honeycomb panels. Designers can freely choose from a variety of surface materials, such as imitation copper rust metal panels, digitally printed ceramics, and wood veneers, without being limited by the physical properties of the materials. This design allows the same structural system to present completely different architectural interior styles.

[0043] More preferably, the hook assembly 22 includes an upper hook 22A and a lower hook 22B. When viewed in a direction parallel to the surface of the honeycomb panel 20, the upper hook 22A is fixedly connected to the honeycomb panel 20, and the lower hook 22B is fixedly connected to the side of the honeycomb panel 20 where the upper hook 22A is provided, and is located below the upper hook 22A in the vertical direction.

[0044] The hook assembly 22 typically includes two upper hooks 22A at the same height and two lower hooks 22B located below the two upper hooks 22A respectively. This four-corner fixing method can form a stable square fixing structure, avoiding unstable hanging due to external forces when fixing with double hooks or single hooks, and preventing the honeycomb panels from swinging, shifting or rotating on the hook connector 11.

[0045] More preferably, the upper hook 22A and the lower hook 22B form a snap-fit ​​space 25 in the vertically downward direction. When the honeycomb aluminum plate 21 passes through the fixing hole 11A and moves in the second direction F2, the edge of the fixing hole 11A snaps into the snap-fit ​​space 25 to fix the honeycomb aluminum plate 21.

[0046] The snap-fit ​​space 25 is a structure used to fix the device to the fixing hole 11A. The width of the abutment part of the internal space is the same as the width of the edge of the fixing hole 11A, so that the upper hook 22A or the lower hook 22B can be smoothly snapped into the edge of the fixing hole 11A. The snap-fit ​​space 25 has a trapezoidal structure that is wider at the bottom and narrower at the top, with a right-angled edge near the honeycomb aluminum plate 21 and an angled edge away from the honeycomb aluminum plate 21. When the edge of the fixing hole 11A enters the snap-fit ​​space 25, the edge of the hole can slide into the abutment part through the angled edge and align with the width of the abutment part to achieve snap-fit ​​fixation.

[0047] More preferably, when viewed along the first direction F1, the shape of the honeycomb hole 21A is hexagonal, and the side length of any side of any honeycomb hole 21A of the honeycomb aluminum plate 21 is the same as the side length of any other side of the honeycomb hole 21A.

[0048] The equilateral hexagonal honeycomb cell design and densely packed cells 21A form a highly efficient space-filling structure. The unique advantage of the equilateral hexagonal honeycomb lies in its isotropic mechanical properties. Regardless of the direction of the external force, the honeycomb structure can uniformly distribute stress through three sets of honeycomb walls at 120-degree angles to each other, effectively improving the stability of the board. Under impact loads, the hexagonal honeycomb absorbs energy first through the elastic bending of the honeycomb walls, and then transfers the force to a wider area through the synergistic effect of adjacent honeycomb cells.

[0049] More preferably, the included angle between any edge of the honeycomb hole 21A and any adjacent edge connected to it is denoted as R, and satisfies the relationship: R = 120°.

[0050] Among them, the 120° included angle between any two adjacent sides of the honeycomb cell 21A is the most stable connection angle on the two-dimensional plane, which enables the honeycomb cell 21A to distribute stress evenly. When the edge of each honeycomb cell 21A maintains a 120° included angle with the edge of the adjacent cell, the entire honeycomb panel forms countless mutually supporting equilateral triangular stable units. When subjected to external forces, this structure can distribute the stress evenly in three symmetrical directions.

[0051] More preferably, the first direction F1 and the second direction F2 are perpendicular to each other.

[0052] In this context, the first direction F1 is perpendicular to the surface of the honeycomb panel. When the honeycomb panel needs to be installed on a vertical wall 200, this direction is horizontal. The second direction F2 is parallel to the surface of the honeycomb panel and is vertical. When the honeycomb panel needs to be installed on a vertical wall 200, the edge of the honeycomb panel is usually parallel to the surface of the wall 200, so this direction is vertical to the ground. Therefore, the first direction F1 and the second direction F2 are perpendicular to each other.

[0053] More preferably, the dry-hanging structure 10 further includes an anchor 12. The anchor 12 is inserted into the wall 200 along the first direction F1 and is pre-embedded and fixed within the wall 200. The hanging member 11 is fixedly connected to the anchor 12.

[0054] Anchor 12, as a primary load-bearing component, is deeply embedded in the concrete wall 200. Through the fixed connection of the hanger 11, it transfers part of the weight and external pressure borne by the honeycomb panels connected to the dry-hanging structure 10 to the wall 200. The hanger 11 can be fixed to the anchor 12 by bolts to achieve force transmission. The hanger 11 can be fixed to the internal thread of the anchor 12 through a nut-like structure. The hanger 11 is fixed between the anchor 12 and the nut by horizontal pressure. This method of fixing the hanger 11 allows for replacement of the hanger 11 and the honeycomb panels without removing the anchor 12; only the nut needs to be removed for disassembly and assembly, allowing the anchor 12 to remain permanently in the wall 200.

[0055] More preferably, the decorative layer 24 is made of one or more of the following materials: aluminum alloy, bio-based resin, photocatalytic self-cleaning glass, stone, polycarbonate, epoxy resin, stainless steel, or ceramic.

[0056] The diverse design of the decorative layer 24 materials allows the composite curtain wall structure 100 to offer more functional performance and aesthetic possibilities. Aluminum alloy, a classic choice, provides excellent weather resistance and a modern feel. Its anodizing treatment can create various color effects such as champagne gold and titanium black, while maintaining excellent color retention, making it suitable for commercial buildings seeking a technological feel. Bio-based resin is an environmentally friendly material, primarily composed of plant fibers or mycelium. Decorative layer 24 containing bio-based resin not only has a lower carbon content than traditional materials but can also achieve natural textures such as wood grain and stone grain through molding processes, meeting green building certification requirements and showcasing artistic effects. Photocatalytic self-cleaning glass and ceramic panels are high-performance decorative surface materials. The photocatalytic glass surface is coated, decomposing organic pollutants under sunlight, keeping the decorative layer 24 surface clean for a long time, and is commonly used for curtain wall decorative layers 24 located on the exterior of buildings. Ceramic panels, sintered at 1200℃, form a stable material structure with good chemical properties, resisting acids and alkalis and freeze-thaw cycles, making them also suitable for exterior curtain wall decorative layers 24. Polycarbonate hollow panels weigh only half as much as glass, yet possess excellent impact resistance, and their light transmittance is adjustable, allowing for dynamic decorative surfaces when combined with LED backlighting and other lighting sources. Epoxy resin-based panels also exhibit extremely high structural strength, making them particularly suitable for curved architectural designs. The combination of these two polymer materials enables curtain walls to achieve lightweight construction while simultaneously delivering other aesthetic benefits. Stainless steel decorative layers 24 can be rendered in special colors such as rose gold and sapphire blue through physical vapor deposition. Stone decorative layers 24, on the other hand, retain the luxurious texture of natural stone from an artistic perspective.

[0057] In this way, the hook assembly 22 passes through the fixing hole 11A along the first direction F1 and enters the hanging member 11, and the hook assembly 22 engages with the edge of the fixing hole 11A along the second direction F2, so that the honeycomb aluminum plate 21 can be quickly fixed to the dry-hanging structure 10 by moving in two directions, which effectively improves the convenience of disassembly and assembly. Furthermore, the design of the honeycomb aluminum plate 21 with a plurality of honeycomb holes 21A inside the honeycomb plate layer 20, and each honeycomb hole 21A penetrating the honeycomb aluminum plate 21 along the first direction F1, results in a large central control area in the honeycomb aluminum plate 21, avoiding excessive weight of the honeycomb plate layer 20.

[0058] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
