Description

Technical Field

[0001] The present invention relates to the technical field of panels, and more particularly to a composite reinforced exterior wall panel. Background Art

[0002] Calcium silicate board or fiber cement board has a long history of use as exterior decorative panels. Calcium silicate board or fiber cement board is a commonly used raw material for exterior decorative panels. In order to balance the relationship between production costs and profits, more and more manufacturers have made the quality of calcium silicate board show a downward trend. The quality of calcium silicate board varies greatly during the production process. The current industry standard for the use of calcium silicate board: JCT 564.1-2018 Fiber-reinforced calcium silicate board Part 1: Asbestos-free calcium silicate board standard shows, the panel requirements for exterior wall thermal insulation decoration integrated panels are not lower than Class A and R3 panels, and curtain walls generally use Class A and R5 panels (Class A and R3 panels require panel saturated water strength of 12MPa and dry strength of 10MPa; Class A and R5 panels require panel saturated water strength of 20MPa and dry strength of 18MPa).

[0003] In the prior art, users have found in actual use that the discreteness of the measured data of core indicators such as the flexural (saturated, dry) strength, impact resistance, and water impermeability of the exterior decorative panels is relatively large, that is, the data values ​​obtained from multiple measurements of these indicators vary greatly and are not stable or consistent, which poses a hidden danger to long-term use. The panels may be damaged or fall off during use, posing a safety hazard to personnel and property. If the water impermeability of the panel is unstable, moisture may penetrate into the building, causing wall damage, mildew, and other problems, thereby shortening the service life of the building. Summary of the invention

[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] Some embodiments of the present application propose a composite reinforced exterior wall panel to solve the technical problems mentioned in the above background technology section.

[0006] As a first aspect of the present application, some embodiments of the present application provide a composite reinforced exterior wall panel, comprising an outer layer panel, a reinforced composite panel and an inner layer panel, wherein the outer layer panel, the reinforced composite panel and the inner layer panel are stacked in sequence; wherein the thickness ratio of the reinforced composite panel to the outer layer panel is in the range of: 0.05 to 0.15; and the reinforced composite panel is made of metal.

[0007] Furthermore, the thickness ratio of the reinforced composite plate to the inner layer plate ranges from 0.05 to 0.2.

[0008] Furthermore, the outer layer board is a calcium silicate board and / or a fiber cement board.

[0009] Furthermore, the outer layer board has a board density of 1.4-1.55 g / cm2 and a thickness range of 4-6 mm.

[0010] Furthermore, a reinforcement coating is provided on a side of the outer plate away from the reinforced composite plate, and the coating amount of the reinforcement coating is greater than or equal to 100 g / cm2.

[0011] Furthermore, a waterproof coating is provided on a side of the outer layer plate away from the reinforced composite plate, and the coating amount of the waterproof coating is greater than or equal to 20g / cm2.

[0012] Furthermore, the material of the reinforced composite plate is an aluminum plate and / or an aluminum-zinc-coated steel plate and / or a stainless steel plate, and the thickness of the reinforced composite plate is in the range of 0.3-0.6 mm.

[0013] Furthermore, the material of the reinforced composite plate is a metal cone core and / or metal corrugation, and the thickness of the reinforced composite plate is in the range of 0.3-0.6 mm.

[0014] Furthermore, the inner layer board is a calcium silicate board and / or a fiber cement board.

[0015] Furthermore, the inner layer board has a board density of 1.3-1.45 g / cm2 and a thickness range of 3-6 mm.

[0016] Furthermore, an outer decorative layer is provided on a side of the outer plate away from the reinforced composite plate, and the outer decorative layer is a water-based exterior wall paint and / or an oil-based exterior wall paint and / or a metal material and / or a PEDF fluorocarbon film.

[0017] Furthermore, a moisture-proof and gas-proof layer is provided on a side of the inner layer plate away from the reinforced composite plate, and the moisture-proof and gas-proof layer is an aluminum film with a thickness ranging from 0.05 to 0.3 mm.

[0018] Furthermore, a moisture-proof and air-proof layer is provided on a side of the inner layer board away from the reinforced composite board, and the moisture-proof and air-proof layer is a silver-plated PET film with a thickness ranging from 0.15 to 0.8 mm.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] (1) The present invention provides a reinforced composite plate between the outer plate and the inner plate, and the reinforced composite plate is made of metal material, thereby effectively improving the bending resistance of the exterior wall plate.

[0021] (2) The present invention provides a reinforced composite plate between the outer plate and the inner plate. The addition of the reinforced composite plate isolates the conduction of water vapor between the outer plate and the inner plate, thereby achieving an effect that the front and back surfaces of the composite plate are almost completely impermeable.

[0022] (3) The present invention sets a reinforced composite board between the outer plate and the inner plate. Compared with the calcium silicate board used in the curtain wall in the prior art, the thickness of the board is ≥12mm when the back bolt dry hanging process is adopted. The calcium silicate board generally adopts a thickness of 15mm and above, and the board is heavy. As a point-hanging curtain wall, the data dispersion of the board itself is relatively large, and there are safety hazards under the action of long-term wind pressure. Through actual measurement and comparison, it can be known that the combination of the reinforced composite board set between the outer plate and the inner plate takes the plate size of 800mm*1200mm*10.3mm as an example. When the thickness is 10.3mm, the overall physical properties are ≥20-25mm. The physical properties of calcium silicate board or fiber cement board have a weight loss of ≥30%.

[0023] (4) The present invention provides a reinforced composite board between the outer board and the inner board. Compared with the single-layer calcium silicate board or fiber cement board used in the curtain wall in the prior art, which is prone to direct fracture and falling off when subjected to a large external impact, the composite board in the present invention does not have the risk of direct fracture of the single-layer board because it is supported by the reinforced composite board. Generally, damage occurs on the outer board, but because there is an elastic adhesive layer between the outer board and the reinforced composite board, the board will not fall off directly after damage occurs, which saves time for later inspection and maintenance.

[0033] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] like Figure 1 As shown, a composite reinforced exterior wall panel of an embodiment of the present application includes an outer panel 200, a reinforced composite panel 300 and an inner panel 400, wherein the outer panel 200, the reinforced composite panel 300 and the inner panel 400 are stacked in sequence; wherein the thickness ratio of the reinforced composite panel 300 to the outer panel 200 is in the range of 0.05 to 0.15, and the thickness ratio of the reinforced composite panel 300 to the inner panel 400 is in the range of 0.05 to 0.2; and the reinforced composite panel 300 is made of metal.

[0036] Specifically, the outer layer plate 200, the reinforced composite plate 300 and the inner layer plate 400 are stacked in sequence, and the reinforced composite plate 300 is arranged between the outer layer plate 200 and the inner layer plate 400. The reinforced composite plate 300 is made of metal, and its strength is much greater than the strength of the outer layer plate 200 and the inner layer plate 400, so it effectively improves the overall flexural performance of the panel.

[0037] More specifically, the thickness ratio of the reinforced composite board 300 to the outer board 200 is in the range of 0.05 to 0.15, wherein the outer board 200 may be a calcium silicate board and / or a fiber cement board, the board density of the outer board 200 is 1.4-1.55 g / cm2, and the thickness range is 4-6 mm, the material of the reinforced composite board 300 is an aluminum board and / or an aluminum-zinc-plated steel board and / or a stainless steel board, and the thickness range of the reinforced composite board 300 is 0.3-0.6 mm. The thickness ratio of the reinforced composite board 300 to the outer board 200 is in the range of 0.05 to 0.15, so that the overall exterior wall board can save production costs while meeting the performance requirements of anti-bending. Similarly, the inner layer board 400 is a calcium silicate board and / or a fiber cement board, the inner layer board 400 has a board density of 1.3-1.45 g / cm2, a thickness range of 3-6 mm, and a thickness ratio of the reinforced composite board 300 to the inner layer board 400 ranges from 0.05 to 0.2, so that the overall exterior wall panel is thinner, which saves production costs while meeting the anti-bending performance requirements.

[0038] A reinforced composite board 300 is arranged between the outer board 200 and the inner board 400. Compared with the calcium silicate board used in the curtain wall in the prior art, the thickness of the board is greater than or equal to 12mm when the back bolt dry hanging process is adopted. The calcium silicate board generally adopts a thickness of 15mm and above, and the board is heavy. As a point-hanging curtain wall, the data dispersion of the board itself is relatively large, and there are safety hazards under the action of long-term wind pressure. Through actual measurement and comparison, it can be known that the combination of the reinforced composite board 300 arranged between the outer board 200 and the inner board 400 takes the plate size of 800mm*1200mm*10.3mm as an example. When the thickness is 10.3mm, the overall physical properties are greater than or equal to the physical properties of the 20-25mm calcium silicate board or fiber cement board, and the weight loss is greater than or equal to 30%.

[0039] In a specific embodiment, when the side of the outer plate 200 away from the reinforced composite plate 300 has no veneer material, the side of the outer plate 200 away from the reinforced composite plate 300 is provided with a reinforcing coating, and the coating amount of the reinforcing coating is greater than or equal to 100g / cm2. The reinforcing coating applied here is an epoxy primer or a UV primer to increase adhesion and meet waterproof requirements. When the side of the outer plate 200 away from the reinforced composite plate 300 has a self-decorated surface (referring to being coated with decorative color paint), the side of the outer plate 200 away from the reinforced composite plate 300 is provided with a waterproof coating, and the coating amount of the waterproof coating is greater than or equal to 20g / cm2. It does not need to add a decorative panel on the outside, so it only needs to meet the waterproof requirements.

[0040] In a specific embodiment, the reinforced composite panel 300 is made of metal, and can be made of mainstream metal flat plates such as aluminum plates, aluminum-zinc-coated steel plates, and stainless steel plates, or can be made of deep-processed metal materials, such as metal cone cores, metal corrugations, etc. The metal thickness is required to be 0.3-0.6 mm, and the reinforced composite panel 300 needs to be pickled and chromized on both sides and treated with an internal bonding interface coating. Pickling can remove oxides and pollutants on the metal surface and provide a clean and active surface for chromization. Chromization can form a dense chromium oxide film on the metal surface after pickling, further improving the corrosion resistance and wear resistance of the metal. When the exterior wall panel needs to meet requirements in a certain direction, for example, the length direction is longer and there is no requirement in the width direction, the reinforced composite panel 300 can be deeply processed in the length direction so that it is constructed into a metal cone core, metal corrugation, etc. to enhance the strength in the length direction.

[0041] In a specific embodiment, an outer decorative layer 100 is provided on a side of the outer plate 200 away from the reinforced composite plate 300, and the outer decorative layer 100 is a water-based exterior wall paint and / or an oil-based exterior wall paint and / or a metal material and / or a PEDF fluorocarbon film. Among them, water-based exterior wall paints include real stone paint, water-in-water, water-in-sand, hard flat paint, etc., and oil-based exterior wall paints include metal fluorocarbon paint, solid color fluorocarbon paint, etc. The metal material generally uses 0.2-0.6mm aluminum plate, aluminum zinc plate, stainless steel plate, etc., and the outer decorative layer 100 of different materials is selected according to different usage scenarios.

[0042] In a specific embodiment, for the curtain wall board, the inner plate 400 is often fixed on the keel, and there is a gap between it and the wall, and there may be water vapor in the gap. A moisture-proof and air-proof layer 500 is provided on the side of the inner plate 400 away from the reinforced composite plate 300. The moisture-proof and air-proof layer 500 is an aluminum film with a thickness range of 0.05-0.3mm. A moisture-proof and air-proof layer 500 is provided on the side of the inner plate 400 away from the reinforced composite plate 300. The moisture-proof and air-proof layer 500 is a silver-plated PET film with a thickness range of 0.15-0.8mm.

[0043] When the composite reinforced exterior wall panels are composed of an outer panel 200, a reinforced composite panel 300 and an inner panel 400, their saturated strength is greater than or equal to 35 MPa, and their dry strength is greater than or equal to 30 MPa. When the composite reinforced exterior wall panels are composed of an outer decorative layer 100, an outer panel 200, a reinforced composite panel 300 and an inner panel 400, or an outer decorative layer 100, an outer panel 200, a reinforced composite panel 300, an inner panel 400 and a moisture-proof and air-tight layer 500, their saturated strength is greater than or equal to 35 MPa, and their dry strength is greater than or equal to 30 MPa.

[0044] A reinforced composite board 300 is arranged between the outer board 200 and the inner board 400. Compared with the single-layer calcium silicate board or fiber cement board used in the curtain wall in the prior art, which is prone to direct fracture and falling off when subjected to a large external impact, the composite board in the present invention does not have the risk of direct fracture of the single-layer board because it is supported by the reinforced composite board 300. Generally, damage occurs on the outer board 200, but because there is an elastic adhesive layer between the outer board 200 and the reinforced composite board 300, the board will not fall off directly after damage occurs, which saves time for later inspection and maintenance.

[0045] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
