Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically a honeycomb composite aluminum single panel. Background Technology

[0002] Aluminum honeycomb panels are a composite material made of aluminum alloy panels and aluminum honeycomb cores bonded together. This structure draws inspiration from the mechanical principles of honeycombs in nature, achieving lightweighting of materials while ensuring strength. Functionally, aluminum honeycomb panels have certain sound insulation and heat insulation properties. The air cavities in the honeycomb core layer can effectively block the transmission of sound and reduce noise interference. The air layers also form thermal resistance, improving the heat insulation effect of buildings. They are mainly used for building decoration.

[0003] Although aluminum honeycomb panels achieve synchronized thermal expansion and contraction through the high thermal conductivity of the inner and outer aluminum skins and the honeycomb core, if the small pores of the honeycomb core are blocked by glue or impurities, the internal gas cannot flow freely. This imbalance of internal and external pressure during thermal expansion and contraction can cause bulging on the panel surface, leading to unevenness and affecting its performance.

[0004] Therefore, we propose a honeycomb composite aluminum single panel to solve the above problems. Utility Model Content

A rectangular gasket 5 is provided in the aluminum panel 1, and an upper micro-perforated thin plate 6 is bonded to the top of the rectangular gasket 5 with an adhesive. An aluminum honeycomb core 7 is bonded to the top surface of the upper micro-perforated thin plate 6 with an adhesive, and a cavity 8 is provided between the top surface of the aluminum honeycomb core 7 and the aluminum panel 1. A lower micro-perforated thin plate 9 is bonded to the bottom of the rectangular gasket 5 with an adhesive, and a fiberglass mat 10 is bonded to the bottom surface of the lower micro-perforated thin plate 9 with an adhesive. The panel 1 has mating protrusions 2 and mating grooves 3 on both sides, with circular holes 4 interconnected on them. A rectangular gasket 5 is set in the aluminum panel 1. The top is composited with a micro-perforated thin plate 6 and an aluminum honeycomb core 7, and there is a cavity 8 between the top surface of the aluminum honeycomb core 7 and the aluminum panel 1. The bottom is composited with a lower micro-perforated thin plate 9, a fiberglass felt 10 and an aluminum back plate 11. The design of the circular holes 4, the cavity 8 and the micro-perforated thin plate allows gas flow. Even if the small holes of the honeycomb core 7 are blocked, the circular holes 4, the cavity 8 and the micro-perforated structure can balance the internal and external pressures during thermal expansion and contraction, avoiding bulging and unevenness of the panel surface. This solves the problem caused by the inability of internal gas flow in the original aluminum honeycomb single panel. The bottom surface of the fiberglass felt 10 is composited with the aluminum back plate 11 by an adhesive.

[0027] like Figure 1 As shown, in some embodiments, the aluminum panel 1 is a groove structure, and the top surface of the aluminum panel 1 is coated with a fluorocarbon coating 12. The fluorocarbon coating 12 has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold and heat resistance, can resist strong ultraviolet radiation, can maintain its color and not powder for a long time, and has a long service life.

[0028] like Figure 3 As shown, in some embodiments, the positions of the mating protrusion 2 and the mating groove 3 are corresponding, and the aluminum panels 1 are spliced ​​together in pairs by the mating protrusion 2 and the mating groove 3. The provided mating protrusion 3 and the mating groove 3 facilitate the splicing and installation between single panels.

[0029] like Figure 3 As shown, in some embodiments, the positions of the circular holes 4 on the mating protrusion 2 and the mating groove 3 correspond to each other and are interconnected. The circular holes 4 are regular array punched holes with a diameter controlled between 1mm and 3mm and a spacing between 5mm and 10mm. The circular holes 4 allow internal air to circulate between each pair of single boards.

[0030] like Figure 3 As shown, in some embodiments, the concave surface of the mating protrusion 2 communicates with the cavity 8, and the convex surface of the mating groove 3 communicates with the cavity 8. Under the action of the cavity 8, a micro-ventilation channel is formed inside the single board.

[0031] like Figure 3 As shown, in some embodiments, the upper micro-perforated thin plate 6 and the aluminum honeycomb core 7 are interconnected, and the upper micro-perforated thin plate 6 and the lower micro-perforated thin plate 9 are interconnected. The aluminum honeycomb core 7 adopts a honeycomb structure with a side length between 5mm and 6mm, a wall thickness controlled between 0.04mm and 0.06mm, and a porosity >95%. The upper micro-perforated thin plate 6 and the lower micro-perforated thin plate 9 are made of 3003 aluminum alloy, with a thickness controlled at 0.5mm, a pore diameter between 0.3mm and 0.5mm, and a perforation rate of 15% ± 1%.

[0032] like Figure 3 As shown, in some embodiments, the aluminum panel 1 has a slot 13 around its bottom perimeter, and the aluminum back plate 11 has a protruding edge 14 around its perimeter. The protruding edge 14 is tightly fitted into the slot 13. The aluminum panel 1 and the aluminum back plate 11 are made of 5052 aluminum alloy with a thickness of 1.0mm. Through the cooperation between the protruding edge and the slot 13, the aluminum back plate 11 is tightly bonded to the aluminum panel 1.

[0033] In use, the fiberglass mat 10 maintains a weight of 100g / m² and an air permeability ≥60m³ / (m²·h). The aluminum panel 1 has mating protrusions 2 and mating grooves 3 on both sides, with interconnected circular holes 4. A rectangular gasket 5 is placed within the aluminum panel 1. The top is composited with a micro-perforated thin plate 6 and an aluminum honeycomb core 7, with a cavity 8 between the top surface of the aluminum honeycomb core 7 and the aluminum panel 1. The bottom is composited with a lower micro-perforated thin plate 9, fiberglass mat 10, and an aluminum backing plate 11. The design of the circular holes 4, the cavity 8, and the micro-perforated thin plate allows for gas flow. Even if the small holes in the honeycomb core 7 are blocked, the circular holes 4, the cavity 8, and the micro-perforated structure can balance the internal and external pressures during thermal expansion and contraction, preventing bulging and unevenness of the panel surface. This solves the problem caused by the inability of internal gas flow in traditional aluminum honeycomb panels.

[0034] In summary, the aluminum panel 1 has mating protrusions 2 and mating grooves 3 on both sides, with interconnected circular holes 4. A rectangular gasket 5 is placed in the aluminum panel 1. The top is composited with a micro-perforated thin plate 6 and an aluminum honeycomb core 7, with a cavity 8 between the top surface of the aluminum honeycomb core 7 and the aluminum panel 1. The bottom is composited with a lower micro-perforated thin plate 9, fiberglass felt 10, and an aluminum back plate 11. The design of the circular holes 4, the cavity 8, and the micro-perforated thin plate allows for gas flow. Even if the small holes of the honeycomb core 7 are blocked, the circular holes 4, the cavity 8, and the micro-perforated structure can balance the internal and external pressures during thermal expansion and contraction, avoiding bulging and unevenness of the panel surface. This solves the problem caused by the inability of internal gas flow in the original aluminum honeycomb single panel.
