Description

Technical Field

[0001] This invention belongs to the technical field of aluminum single-panel curtain walls, and particularly relates to a lightweight corrosion-resistant aluminum single-panel curtain wall and its preparation method. Background Technology

[0002] With the rapid development of the modern construction industry, the demand for building exterior wall decoration materials is constantly increasing. Traditional building exterior wall materials such as stone and glass, while offering good decorative effects, have limitations in terms of weight, corrosion resistance, and ease of installation. Aluminum single-panel panels, as a new type of building decoration material, have been widely used in the field of building exterior wall decoration due to their advantages such as lightweight, high strength, corrosion resistance, and ease of processing and forming. However, existing lightweight corrosion-resistant aluminum single-panel curtain walls have relatively simple structures. When installed on the exterior of buildings, the external protection of the aluminum single-panel curtain wall is relatively poor, and the surface of the aluminum single-panel curtain wall is prone to corrosion and aging, thus affecting its service life.

[0003] To address this, Chinese patent CN219732445U discloses an environmentally friendly aluminum panel for curtain walls with corrosion resistance, comprising an aluminum panel body, sealing rings, and sealing strips. The aluminum panel body includes an upper panel and an lower panel, which are rotatably connected via hinges. Both the upper and lower panels have two grooves on their outer sides, each engaging with a corresponding sealing ring. The bottom and top ends of the upper panel have a first slot and a second slot, respectively, both engaging with the sealing strips. The upper panel can rotate on the lower panel via the hinges, allowing for folding of either panel for easy handling. The sealing strip engages with the first and second slots, improving the seal between the upper and lower panels. Simultaneously, the sealing rings engage with the grooves, improving the seal between adjacent aluminum panel bodies.

[0004] Although the above-mentioned device enhances the corrosion resistance to a certain extent through waterproofing, the hinge connection between the upper and lower single panels is more prone to loosening, deformation, or even falling off compared to stabilizing methods such as welding. This results in a weaker overall structural strength, leading to poorer protection against earthquakes and pressure, and affecting the service life of the aluminum single panel. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a lightweight, corrosion-resistant aluminum panel for curtain walls and its preparation method. This invention effectively improves the structural strength and compressive strength of the aluminum panel, while also providing sound insulation, heat insulation, and earthquake protection. It effectively enhances the anti-corrosion and anti-aging properties, providing comprehensive protection for the aluminum panel and thus extending its service life. This invention solves the problem in the prior art where the overall structural strength of the aluminum panel is weak, resulting in poor earthquake and compressive resistance and affecting its service life.

[0006] This invention is implemented as follows: a lightweight, corrosion-resistant aluminum panel for curtain walls includes an aluminum panel body. A reinforcing plate is fixedly connected to the inner wall of the aluminum panel body. From the inside to the outside, the interior of the aluminum panel body is provided with a honeycomb panel, a polyurethane sound insulation panel, a rock wool heat insulation panel, a rubber buffer panel, and a panel. The reinforcing plate has a cross-shaped structure and divides the interior of the aluminum panel body into four parts. The honeycomb panel and the polyurethane sound insulation panel are fixedly connected between the reinforcing plate and the aluminum panel. The polyurethane sound insulation panel is inserted into the surface of the honeycomb panel. The rock wool heat insulation panel is fixed to the surface of the polyurethane sound insulation panel. The panel is inserted into the front of the reinforcing plate. The rubber buffer panel is pressed between the rock wool heat insulation panel and the panel. The outer surfaces of the panel and the aluminum panel body are both fixed with an anti-corrosion coating.

[0007] This design, through the use of reinforcing plates, honeycomb panels, and polyurethane sound insulation panels, not only enhances the structural strength and compressive strength of the aluminum plate, but also improves its sound insulation effect. Furthermore, the use of rubber buffer panels, rock wool insulation panels, panels, and anti-corrosion coatings improves its shock absorption, compressive strength, thermal insulation, and corrosion resistance, thus comprehensively enhancing the protection of the aluminum plate and effectively extending its service life.

[0008] By combining a sun-protective film layer, an anti-corrosion coating, and a sealing silicone strip, the corrosion resistance, anti-aging properties, and corrosion resistance are enhanced, thereby effectively strengthening the protective capabilities of the aluminum plate and extending its service life.

[0009] As a preferred embodiment of the present invention, a weight-reducing slot is provided on the front side of the reinforcing plate, and a rubber plug is fixedly connected to the inner wall of the panel. Both the rubber plug and the weight-reducing slot are arranged in a cross shape, and the rubber plug is inserted into the weight-reducing slot.

[0010] This design, with its cross-shaped reinforcing plate, effectively enhances the overall structural strength of the aluminum plate and improves its compressive strength. The weight-reducing slot not only helps to reduce the weight of the reinforcing plate but also facilitates the insertion and positioning of the rubber inserts, ensuring stable installation of the panel with accurate positioning and ease of use.

[0011] As a preferred embodiment of the present invention, mounting holes are provided between the four ends of the panel and the rubber insert, and corresponding mounting thread grooves are provided on the inner wall of the aluminum single panel body. Bolts are inserted into the mounting holes and the ends of the bolts are threadedly connected to the mounting thread grooves.

[0012] This design facilitates the removal and installation of the panel, making it flexible and convenient to use. When installing the panel, the screw is inserted into the mounting hole and tightened into the mounting thread groove. At this time, the nut is pressed against the outer wall of the panel, achieving a stable installation of the panel.

[0013] As a preferred embodiment of the present invention, the honeycomb plate has uniformly distributed honeycomb holes, the inside of the polyurethane sound insulation board is fixedly connected to uniformly distributed honeycomb cylinders, the honeycomb cylinders are inserted into the hole walls of the honeycomb holes, and the inside of the honeycomb cylinders is fixedly connected to polyester fiber sound-absorbing cotton sheets.

[0014] This design, with its honeycomb holes, helps to reduce the weight of the honeycomb panel. The combination of honeycomb holes, honeycomb tubes, and polyurethane sound insulation panels not only further enhances the overall structural strength of the aluminum panel but also effectively blocks the transmission of sound. Furthermore, the polyester fiber sound-absorbing cotton sheet can absorb sound again, further enhancing the sound insulation effect.

[0015] As a preferred embodiment of the present invention, rubber protrusions are fixedly connected to both sides of the rubber buffer plate. A plurality of rubber protrusions are provided and evenly distributed along both sides of the rubber buffer plate. One side of the rubber protrusions abuts against the surface of the rock wool insulation board, and the other side of the rubber protrusions abuts against the inner surface of the panel.

[0016] This design, through the combination of rubber buffer plates, rubber ridges, and rock wool insulation boards, effectively improves the overall shock absorption and thermal insulation capabilities of the aluminum plate, thereby extending its service life. Furthermore, the rubber ridges enhance friction between the rubber buffer plate and the panel, as well as the rock wool insulation board, strengthening the connection between them. It is convenient to use, and the rubber buffer plate can be easily replaced when disassembling the panel, ensuring its shock and pressure resistance, and offering flexible application.

[0017] As a preferred embodiment of the present invention, a sun-protective film layer is fixedly connected to the anti-corrosion coating on the outer surface of the panel. The sun-protective film layer is made of transparent polyester film material, and the anti-corrosion coating is a three-coat fluorocarbon coating.

[0018] This design enhances the corrosion resistance of the aluminum plate, and the polyester film sunscreen layer effectively resists the erosion of the aluminum plate by acid rain, salt spray, and corrosive media. It also effectively blocks ultraviolet rays, reduces the aging effect of ultraviolet rays on the aluminum plate, and improves its corrosion resistance.

[0019] As a preferred embodiment of the present invention, a sealing silicone strip is fixedly connected between the four sides of the panel and the inner wall of the aluminum single-panel body.

[0020] This design enhances the sealing of the aluminum plate, improving its waterproof performance and thus facilitating further enhancement of its corrosion resistance.

[0021] A method for preparing a lightweight corrosion-resistant aluminum curtain wall panel, applicable to the aforementioned lightweight corrosion-resistant aluminum curtain wall panel, includes the following steps: S1. Material preparation: Aluminum alloy aluminum sheet is selected as the main body of aluminum single panel, cross-shaped reinforcing plate, honeycomb panel, polyurethane sound insulation board, rock wool heat insulation board, rubber buffer board, panel and anti-corrosion coating. S2. Installation work: Weld the cross-shaped reinforcing plate to the inner wall of the aluminum single panel body to separate its internal space, and install the honeycomb panel, polyurethane sound insulation board, rock wool heat insulation board, rubber buffer board and panel in sequence. Weld the honeycomb panel between the reinforcing plate and the aluminum single panel body, insert and bond the polyurethane sound insulation board to the honeycomb panel, bond the rock wool heat insulation board to the polyurethane sound insulation board, insert the rubber buffer board into the rock wool heat insulation board, and finally insert the panel into the front of the reinforcing plate so that the rubber buffer board is clamped between the rock wool heat insulation board and the panel, and seal it with sealant. S3. Coating construction: Clean the outer surface of the panel and aluminum single panel body to remove oil, dust and impurities, and apply the anti-corrosion coating evenly by spraying.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: by combining the reinforcing plate, the weight-reducing slot, the rubber insert and the mounting hole, the structural strength is enhanced and the compressive strength is improved, and the panel is conveniently positioned and disassembled. By combining honeycomb panels, honeycomb holes, polyurethane sound insulation panels, honeycomb tubes and polyester fiber sound-absorbing cotton sheets, multiple enhancements in sound insulation are achieved while reducing weight and further strengthening the structure. The combination of rubber buffer plates, rubber ridge strips, rock wool insulation boards, rubber inserts and panels improves the buffering and shock resistance, pressure resistance, and thermal insulation performance. By combining a sun-protective film layer, an anti-corrosion coating, and a sealing silicone strip, the corrosion resistance, anti-aging properties, and corrosion resistance are enhanced, thereby effectively strengthening the protective capabilities of the aluminum plate and extending its service life.

[0025] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] refer to Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a lightweight corrosion-resistant aluminum single-panel curtain wall, including an aluminum single-panel body 1. A reinforcing plate 3 is fixedly connected to the inner wall of the aluminum single-panel body 1. The interior of the aluminum single-panel body 1 is provided with a honeycomb panel 4, a polyurethane sound insulation board 5, a rock wool heat insulation board 6, a rubber buffer board 7, and a panel 2 in sequence from the inside to the outside. The reinforcing plate 3 has a cross-shaped structure and divides the interior of the aluminum single-panel body 1 into four parts. The honeycomb panel 4 and the polyurethane sound insulation board 5 are fixedly connected between the reinforcing plate 3 and the aluminum single-panel. The polyurethane sound insulation board 5 is inserted into the surface of the honeycomb panel 4. The rock wool heat insulation board 6 is fixed to the surface of the polyurethane sound insulation board 5. The panel 2 is inserted into the front of the reinforcing plate 3. The rubber buffer board 7 is pressed between the rock wool heat insulation board 6 and the panel 2. The outer surfaces of the panel 2 and the aluminum single-panel body 1 are both fixed with an anti-corrosion coating 101.

[0028] By adopting the above scheme, the reinforcement plate 3, honeycomb plate 4, and polyurethane sound insulation plate 5 not only enhance the structural strength and compressive strength of the aluminum plate, but also improve the sound insulation effect. The rubber buffer plate 7, rock wool heat insulation plate 6, panel 2, and anti-corrosion coating 101 improve the buffering and shock resistance, compressive strength, heat insulation and heat preservation performance, and corrosion resistance, thereby enhancing the protection effect of the aluminum plate in multiple ways, effectively enhancing the protective ability of the aluminum plate and extending its service life.

[0029] The sun protection film layer 102, the anti-corrosion coating 101, and the sealing silicone strip 8 work together to improve the anti-corrosion, anti-aging, and corrosion resistance properties, thereby effectively enhancing the protective ability of the aluminum plate and extending its service life.

[0030] Specifically, the front of the reinforcing plate 3 is provided with a weight-reducing slot 301, and the inner wall of the panel 2 is fixedly connected with a rubber plug 202. Both the rubber plug 202 and the weight-reducing slot 301 are arranged in a cross shape, and the rubber plug 202 is inserted into the weight-reducing slot 301.

[0031] By adopting the above scheme, the reinforcing plate 3 with the cross-shaped structure effectively enhances the overall structural strength of the aluminum plate and improves its compressive strength. In addition, the weight-reducing slot 301 not only helps to reduce the weight of the reinforcing plate 3, but also facilitates the insertion and positioning of the rubber plug 202 to achieve stable installation of the panel 2. The positioning is accurate and the use is convenient.

[0032] Specifically, mounting holes 201 are provided between the four ends of the panel 2 and the rubber insert 202, and corresponding mounting thread grooves 103 are provided on the inner wall of the aluminum single panel body 1. Bolts are inserted into the mounting holes 201 and the ends of the bolts are threadedly connected to the mounting thread grooves 103.

[0033] The above solution facilitates the disassembly and installation of panel 2, and is flexible and convenient to use. When installing panel 2, the screw is inserted into the mounting hole 201 and tightened into the mounting thread groove 103. At this time, the nut is pressed against the outer wall of panel 2, so as to achieve a stable installation of panel 2.

[0034] Specifically, the honeycomb panel 4 has uniformly distributed honeycomb holes 401, and the inside of the polyurethane sound insulation board 5 is fixedly connected to uniformly distributed honeycomb cylinders 501. The honeycomb cylinders 501 are inserted and fixed in the hole wall of the honeycomb holes 401, and the inside of the honeycomb cylinders 501 is fixedly connected to polyester fiber sound-absorbing cotton sheets 502.

[0035] By adopting the above scheme, the weight of the honeycomb panel 4 can be reduced by the honeycomb holes 401. The combination of the honeycomb holes 401, the honeycomb tube 501 and the polyurethane sound insulation board 5 can not only further enhance the overall structural strength of the aluminum plate, but also effectively block the transmission of sound. In addition, the polyester fiber sound-absorbing cotton sheet 502 can absorb sound again, which enhances the sound insulation effect.

[0036] Specifically, rubber protrusions 701 are fixedly connected to both sides of the rubber buffer plate 7. Several rubber protrusions 701 are provided and evenly distributed along both sides of the rubber buffer plate 7. One side of the rubber protrusions 701 is pressed against the surface of the rock wool insulation board 6, and the other side of the rubber protrusions 701 is pressed against the inner surface of the panel 2.

[0037] By adopting the above solution, the combination of rubber buffer plate 7, rubber convex strip 701 and rock wool insulation board 6 effectively improves the overall shock absorption and heat insulation capacity of the aluminum plate, thereby helping to extend the service life of the aluminum plate. Moreover, the rubber convex strip 701 helps to enhance the friction between the rubber buffer plate 7 and the panel 2 and the rock wool insulation board 6, and helps to enhance the stability of the connection between the rubber buffer plate 7 and the panel 2 and the rock wool insulation board 6. It is convenient to use, and the rubber buffer plate 7 can be easily replaced when the panel 2 is disassembled, ensuring its shock absorption and pressure resistance effect, and making it flexible in use.

[0038] Specifically, a sunscreen film layer 102 is fixedly connected to the anti-corrosion coating 101 on the outer surface of the panel 2. The sunscreen film layer 102 is made of transparent polyester film material, and the anti-corrosion coating 101 is a three-coat fluorocarbon coating.

[0039] The above-mentioned solution is beneficial to enhance the corrosion resistance of aluminum plates. The polyester film sunscreen layer 102 can effectively resist the erosion of aluminum plates by acid rain, salt spray and corrosive media, effectively block ultraviolet rays, reduce the aging effect of ultraviolet rays on aluminum plates, and improve corrosion resistance.

[0040] Specifically, a sealing silicone strip 8 is fixedly connected between the four sides of the panel 2 and the inner wall of the aluminum single panel body 1.

[0041] The above solution enhances the sealing of the aluminum plate, which helps improve its waterproof performance and, consequently, facilitates further enhancement of its corrosion resistance.

[0042] A method for preparing a lightweight corrosion-resistant aluminum curtain wall panel, applicable to the aforementioned lightweight corrosion-resistant aluminum curtain wall panel, includes the following steps: S1. Material preparation: Aluminum alloy aluminum plate is selected as the main body of aluminum single panel 1, cross-shaped reinforcing plate 3, honeycomb panel 4, polyurethane sound insulation board 5, rock wool heat insulation board 6, rubber buffer board 7, panel 2 and anti-corrosion coating. S2. Installation work: Weld the cross-shaped reinforcing plate 3 to the inner wall of the aluminum single panel body 1 to separate its internal space, and install the honeycomb panel 4, polyurethane sound insulation board 5, rock wool heat insulation board 6, rubber buffer board 7 and panel 2 in sequence. Weld the honeycomb panel 4 between the reinforcing plate 3 and the aluminum single panel body 1. Insert and bond the polyurethane sound insulation board 5 to the honeycomb panel 4. Bond the rock wool heat insulation board 6 to the polyurethane sound insulation board 5. Insert the rubber buffer board 7 into the rock wool heat insulation board 6. Finally, insert the panel 2 into the front of the reinforcing plate 3 so that the rubber buffer board 7 is clamped between the rock wool heat insulation board 6 and the panel 2, and seal it with sealant. S3. Coating construction: Clean the outer surfaces of panel 2 and aluminum single panel body 1 to remove oil, dust and impurities, and apply anti-corrosion coating 101 evenly by spraying.

[0043] Working principle of the invention: In use, the combination of reinforcing plate 3, weight-reducing slot 301, rubber insert 202, and mounting hole 201 enhances structural strength and improves compressive strength, while also facilitating the positioning and disassembly of panel 2. The combination of honeycomb panel 4, honeycomb hole 401, polyurethane sound insulation board 5, honeycomb cylinder 501, and polyester fiber sound-absorbing cotton sheet 502 reduces weight, further strengthens the structure, and simultaneously enhances sound insulation. The combination of rubber buffer plate 7, rubber convex strip 701, rock wool heat insulation board 6, rubber insert 202, and panel 2 improves buffering, shock absorption, compressive strength, and heat insulation performance. The combination of sun-protective film layer 102, anti-corrosion coating 101, and sealing silicone strip 8 collectively enhances corrosion resistance, aging resistance, and corrosion resistance, effectively strengthening the protective capabilities of the aluminum plate and extending its service life.
