Abstract
Description
Technical Field
[0001] This utility model relates to the field of building curtain wall technology, and in particular to a new type of high-performance aluminum single panel for building curtain walls. Background Technology
[0002] A curtain wall is the exterior cladding of a building, hung on the building's walls like a curtain. It is a lightweight wall material with decorative effects commonly used in modern large and high-rise buildings. In recent years, as building curtain walls have developed towards larger spans, lighter weight, and higher performance, traditional aluminum single panels have gradually become unable to meet the needs of complex projects due to insufficient bending stiffness and easy deformation.
[0003] Chinese utility model patent CN213653899U discloses a composite high-strength aluminum single panel, comprising an aluminum single panel, reinforcing plates, and a base. The bottom of the aluminum single panel has a groove, within which two reinforcing plates are movably fixed. These plates are interlocked and tightly fitted together. Each reinforcing plate has five layers: an alloy plate, a stainless steel plate, a porous metal material, a foam glass board, and a phenolic board. While this structure increases the strength of the aluminum single panel and reduces deformation, it also significantly increases weight, material usage, and processing costs. Therefore, there is an urgent need for a new aluminum single panel structure that achieves lightweight design while maintaining high bending strength to meet the high-performance curtain wall requirements of super high-rise buildings and large-span stadiums. Utility Model Content
[0004] The purpose of this invention is to provide a new type of high-performance aluminum single panel for building curtain walls to solve the problems mentioned in the background art.
[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a novel aluminum single panel for high-performance building curtain walls, comprising a substrate, wherein the substrate has a first folded edge around its perimeter, and further comprising:
[0006] A base plate is disposed on the back side of the substrate, and a second folded edge is provided around the base plate, the second folded edge being fixedly connected to the first folded edge;
[0007] A carbon fiber reinforcement layer is disposed on the side of the base plate facing away from the substrate;
[0008] A honeycomb core panel is disposed between the substrate and the base plate;
[0009] A reinforcing rib is provided on the side of the base plate facing away from the substrate, and the carbon fiber reinforcement layer is distributed on both sides of the reinforcing rib.
[0010] Preferably, the side of the reinforcing rib facing the base plate is provided with a spacing groove, and the spacing groove is linearly distributed along the length direction of the reinforcing rib.
[0011] Preferably, the spacer groove is a V-shaped groove.
[0012] Preferably, the carbon fiber reinforced layer has a connecting portion that is obliquely embedded in the spacer groove at a 45° angle at one end near the reinforcing rib.
[0013] Preferably, the diameter of the honeycomb cells in the honeycomb core panel gradually decreases from the substrate to the bottom plate.
[0014] Preferably, a closed cavity is provided between the first folded edge and the second folded edge.
[0015] Preferably, the second folded edge is inclined outward relative to the base plate, and the end of the second folded edge is fixedly connected to the second folded edge, forming a triangular closed cavity between the first folded edge and the second folded edge.
[0016] Preferably, a water-blocking edge is provided on the first folded edge at the lower end of the substrate, a guide groove is formed between the water-blocking edge and the second folded edge, and a drainage hole is provided on the water-blocking edge.
[0017] The beneficial effects of this utility model are:
[0018] This utility model forms a relatively closed and stable frame structure by setting folded edges and fixing them around the base plate and bottom plate, which can effectively enhance the overall rigidity of the aluminum single panel, making it less prone to deformation when subjected to external forces and improving the structural stability of the building curtain wall.
[0019] The honeycomb core panel, placed between the substrate and the base plate, provides excellent internal support for the aluminum panel, further enhancing its load-bearing capacity and resistance to deformation. It also reduces the overall weight of the aluminum panel, achieving a combination of lightweight and high strength. The carbon fiber reinforcement layer significantly improves the mechanical properties of the aluminum panel, enabling it to withstand greater external forces without damage.

[0027] Example:
[0028] like Figure 1 and Figure 2 As shown, a new type of high-performance building curtain wall aluminum single panel includes a substrate 1, a honeycomb core panel 2, a bottom plate 3, a carbon fiber reinforcement layer 4, and reinforcing ribs 5. The bottom plate 3 is disposed on the back of the substrate 1, the honeycomb core panel 2 is disposed between the substrate 1 and the bottom plate 3, the carbon fiber reinforcement layer 4 is disposed on the side of the bottom plate 3 facing away from the substrate 1, and the reinforcing ribs 5 are disposed on the side of the bottom plate 3 facing away from the substrate 1. The carbon fiber reinforcement layer 4 is distributed on both sides of the reinforcing ribs 5.
[0029] The honeycomb core panel 2 is connected between the substrate 1 and the base plate 3 by welding or bonding. The carbon fiber reinforcement layer 4 is bonded to the surface of the base plate 3 by carbon fiber tape. The reinforcing rib 5 is connected to the base plate 3 by welding.
[0030] The substrate 1 has a first folded edge 101 around its perimeter. The first folded edge 101 has a height of 30-40mm and is bent outward at 90°.
[0031] The base plate 3 has a second folded edge 301 around its perimeter. The height of the second folded edge 301 is 20-25mm. The second folded edge 301 is fixedly connected to the first folded edge 101 by welding or riveting.
[0032] like Figure 3 As shown, the second folded edge 301 is inclined outward relative to the base plate 3, and the end of the second folded edge 301 is fixedly connected to the second folded edge 301. A triangular closed cavity 6 is formed between the first folded edge 101 and the second folded edge 301, and the edge stiffness is improved through the closed cavity 6.
[0033] A water-blocking edge 102 is provided on the first folded edge 101 at the lower end of the substrate 1. A guide groove 7 is formed between the water-blocking edge 102 and the second folded edge 301. A drain hole 103 is provided on the water-blocking edge 102.
[0034] The diameter of the honeycomb cells 201 in the honeycomb core panel 2 gradually decreases from the substrate 1 to the bottom plate 3, forming a gradient compressive strength. The large-diameter area near the substrate 1 absorbs wind vibration energy, while the small-diameter area on the side of the bottom plate 3 provides high bending support.
[0035] The side of the reinforcing rib 5 facing the base plate 3 is provided with a spacer groove 501, which is linearly distributed along the length of the reinforcing rib 5.
[0036] The spacer groove 501 is a V-shaped groove, and the end of the carbon fiber reinforced layer 4 near the reinforcing rib 5 has a connecting part 401 that is embedded in the spacer groove 501 at a 45° angle to improve the bonding strength of the carbon fiber reinforced layer 4.
