Description

Technical Field

[0001] This utility model relates to the technical field of heat insulation board devices, specifically to a heat insulation aluminum board for building roofs. Background Technology

[0002] In the construction industry, insulated aluminum panels are widely used as roofing building materials. They achieve thermal insulation through structural design and material combination to reduce the conduction of external heat into the interior, thereby improving the building's energy efficiency and comfort.

[0003] Traditional aluminum roof insulation panels have significant drawbacks in practical applications: some existing technologies improve insulation performance by adding a foam insulation layer (such as polyurethane foam), but foam materials are susceptible to aging and shedding due to environmental factors during long-term use, thus losing their insulation function. Other technical solutions employ hollow aluminum panel structures, attempting to achieve insulation through cavities, but due to the lack of an effective internal support structure, the aluminum panels have poor wind pressure resistance, and the cavities are prone to deformation and failure under external pressure or long-term use, failing to guarantee long-term insulation performance. Utility Model Content

[0004] (I) Technical Issues

[0005] This utility model provides a heat-insulating aluminum plate for building roofs that can effectively overcome the defects of existing heat-insulating aluminum plates, such as easy aging, resistance to wind pressure difference, and easy failure of cavities.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a heat-insulating aluminum plate for building roofs, comprising an aluminum plate substrate, an upper reflective layer, a cavity heat-insulating layer, a supporting structure, a lower protective cover, and a connecting structure; the upper reflective layer is fixedly covered on the upper surface of the aluminum plate substrate; the lower protective cover wraps around the bottom of the aluminum plate substrate and is made of aluminum plate material; the supporting structure is vertically fixedly connected to the aluminum plate substrate and the lower protective cover, and the supporting structure is hollow and filled with heat-insulating material; the cavity heat-insulating layer is located between the aluminum plate substrate and the lower protective cover and is separated by the supporting structure to form a closed honeycomb or grid-like air cavity; the connecting structure is located on both sides of the aluminum plate substrate for assembling multiple aluminum plates.

[0008] Furthermore, the support structure is a columnar support with equal spacing, and the internal insulation material is a composite of hydrophobic aerogel particles and ceramic fiber felt.

[0009] Furthermore, the upper reflective layer is a zinc-plated layer.

[0010] Furthermore, the connection structure includes buckles fixed on both sides of the aluminum plate substrate, and the buckles between adjacent heat-insulating aluminum plates are fixed by bolts.

[0012] (III) Technical Effects

[0013] Compared with the prior art, the advantages of this utility model are as follows: by setting a galvanized layer on the upper surface as an upper reflective layer, solar radiation heat is effectively reflected, reducing the heat absorption of the aluminum plate substrate; the honeycomb or grid-like air cavity formed between the aluminum plate substrate and the lower protective cover utilizes the low thermal conductivity of air to achieve heat insulation, while the supporting structure adopts columnar supports arranged at equal intervals, which not only ensures structural stability but also avoids cavity deformation and improves wind pressure resistance; the interior of the supporting structure is filled with a composite of hydrophobic aerogel particles and ceramic fiber felt, which uses a "sandwich" structure to further enhance the heat insulation effect, and the hydrophobic aerogel particles and ceramic fiber felt have excellent aging resistance, ensuring long-term heat insulation.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figure 1 To be continued Figure 7 A heat-insulating aluminum panel for building roofs includes an aluminum panel substrate 1, an upper reflective layer 2, a cavity heat-insulating layer 3, a supporting structure 4, a lower protective cover 5, and a connecting structure 6. The upper reflective layer 2 is fixedly covered on the upper surface of the aluminum panel substrate 1 and is a galvanized layer. The lower protective cover 5 wraps around the bottom of the aluminum panel substrate 1 and is made of aluminum plate material. The supporting structure 4 vertically connects the aluminum panel substrate 1 and the lower protective cover 5. The supporting structure 4 is hollow inside and filled with heat-insulating material 41. The cavity heat-insulating layer 3 is located between the aluminum panel substrate 1 and the lower protective cover 5 and is separated by the supporting structure 4 to form a closed honeycomb or grid-like air cavity. The connecting structure 6 is located on both sides of the aluminum panel substrate 1 and is used for assembling multiple aluminum panels. The connecting structure 6 includes buckle plates 61 fixed on both sides of the aluminum panel substrate 1. The buckle plates 61 between adjacent heat-insulating aluminum panels are fixed by bolts.

[0026] The support structure 4 is a columnar support with equal spacing, and the thermal insulation material 41 inside is a composite of hydrophobic aerogel particles and ceramic fiber felt. The composite of hydrophobic aerogel particles and ceramic fiber felt includes hydrophobic aerogel particles 411 in the center and ceramic fiber felts 412 on both sides. The hydrophobic aerogel particles 411 and the two layers of ceramic fiber felt 412 form a "sandwich" structure filling the inner cavity of the support structure 4.

[0027] The working principle of this utility model is as follows: The thermally insulated aluminum roof panel of this building achieves efficient thermal insulation and structural stability through the coordinated work of multiple components. First, the upper reflective layer 2 is a galvanized layer, which, due to its high reflectivity, reflects solar radiation heat away, reducing the heat absorbed by the aluminum panel substrate 1. The aluminum panel substrate 1 serves as the main structure, providing basic support. Between the aluminum panel substrate 1 and the lower protective cover 5, a closed honeycomb or grid-like cavity thermal insulation layer 3 is formed by the support structure 4. Air, as a poor conductor of heat, fills the air cavity, effectively blocking heat conduction and playing a thermal insulation role. At the same time, the support structure 4 consists of equally spaced columnar supports that vertically and fixedly connect the aluminum panel substrate 1 and the lower protective cover 5, not only maintaining the stable shape of the cavity thermal insulation layer 3 and preventing air cavity deformation and failure, but also enhancing the overall wind pressure resistance of the aluminum panel. The "sandwich" structure thermal insulation material 41 formed by the hydrophobic aerogel particles 411 and ceramic fiber felt 412 filling the support structure 4 further improves the thermal insulation performance. Hydrophobic aerogel particles 411 have extremely low thermal conductivity, while ceramic fiber felt 412 serves to assist in heat insulation and protect the aerogel particles. Together, they block heat conduction through the supporting structure 4. The lower protective cover 5 uses aluminum plate material to wrap the bottom of the aluminum plate base 1, which, together with the supporting structure 4, enhances the overall strength of the aluminum plate. The connecting structure 6 is located on both sides of the aluminum plate base 1, and the fastening plates 61 are fixed with bolts to achieve stable assembly between multiple aluminum plates, ensuring the structural integrity and stability of the entire roof insulation aluminum plate system.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
