Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a reinforced exterior wall insulation board. Background Art

[0002] Exterior wall panels are an integral part of modern architectural design. They not only impact the aesthetics of a building's exterior, but also play a crucial role in protecting the structure from the elements. Traditional exterior wall materials are mostly solid structures like brick, stone, or concrete. However, these materials are often heavy, complex to construct, and offer limited thermal and sound insulation performance.

[0003] In traditional building insulation technology, exterior wall insulation panels are typically made from a single insulation material, such as polystyrene boards or rock wool boards. However, these materials often suffer from low strength and poor durability. Especially under extreme weather conditions, such as strong winds, heavy rain, or snow loads, these insulation panels are prone to deformation or even separation, posing a safety hazard to the building. Furthermore, with increasing demand for building energy efficiency, the thermal insulation performance of traditional insulation materials is no longer able to meet increasingly stringent building energy efficiency standards. Existing insulation panels are often installed by screwing them directly through the panels. While simple and effective, this method can lead to the following problems during installation: If the screws pass through the vacuum insulation panel, the integrity of the vacuum layer will be compromised, significantly reducing the insulation performance of the vacuum insulation panel. Screws that penetrate the insulation panel may also damage its structural integrity, making it more susceptible to deformation or damage when subjected to external forces.

[0004] In order to solve the above technical problems, the present invention designs a reinforced exterior wall insulation board. Utility Model Content

[0005] The utility model provides a reinforced exterior wall insulation board, which aims to solve the problems of low strength and poor insulation performance of existing exterior wall boards and damage to the insulation board by traditional installation methods. The technical solution is as follows:

[0006] A reinforced exterior wall insulation board: comprising an insulation board and a connecting ear board, wherein the connecting ear board is mounted on the side of the insulation board; the insulation board comprises a vacuum insulation board, a steel wire mesh, a Class A insulation slurry, a mesh cloth and an outer protective layer; the steel wire mesh is attached to the four sides of the vacuum insulation board, the Class A insulation slurry is coated on the four sides of the steel wire mesh, mesh cloths are respectively arranged on the upper and lower sides of the Class A insulation slurry away from the vacuum insulation board, and the outer protective layer is bonded to the outer side of the mesh cloth.

[0007] Based on the above technical solution, the vacuum insulation panel includes a barrier film, a core material and a gas adsorbent material. The core material is located inside the barrier film, and a gas adsorbent is attached to the surface of the core material.

[0008] Based on the above technical solution, the core material is glass fiber, silica aerogel or microporous polyurethane.

[0009] Furthermore, a reinforcement layer is provided between the Class A thermal insulation slurry and the mesh cloth.

[0010] Preferably, the mesh cloth is an alkali-resistant mesh cloth.

[0011] Preferably, the insulation board is provided with a protrusion and an insertion portion on the upper and lower parts respectively, and the protrusion and the insertion portion are consistent in shape.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: on the one hand, by adopting a vacuum insulation panel as the core of the thermal insulation material and maintaining a vacuum state inside it, heat conduction is greatly reduced, providing an excellent thermal insulation effect. In addition, the gas adsorbent inside the vacuum insulation panel can adsorb gases that may leak and maintain a high vacuum degree, thereby keeping the thermal insulation performance intact and significantly improving the thermal insulation effect of the thermal insulation panel. On the other hand, by attaching a steel mesh around the thermal insulation panel and providing a reinforcement layer between the steel mesh and the Class A thermal insulation slurry, such as a composite material such as carbon fiber or glass fiber, the mechanical strength of the thermal insulation panel is enhanced. In addition, by providing protrusions and insertion portions of the same shape at the upper and lower ends of the thermal insulation panel, and installing connecting ear plates on the sides of the thermal insulation panel, it is ensured that the thermal insulation panels can be tightly spliced ​​together, thereby enhancing the overall structural stability of the thermal insulation system and preventing the thermal insulation panel from deforming or falling off under extreme weather conditions.

[0017] The present invention will be further described below with reference to the accompanying drawings and examples:

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0020] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figure 1 and Figure 2 As shown, a reinforced exterior wall insulation board is characterized in that it includes an insulation board and a connecting ear plate 6, the connecting ear plate 6 is installed on the side of the insulation board, the insulation board includes a vacuum insulation panel 1, a steel wire mesh 2, a Class A insulation slurry 3, a mesh cloth 4 and an outer protective layer 5, the steel wire mesh 2 is attached to the four sides of the vacuum insulation panel 1, the Class A insulation slurry 3 is coated on the four sides of the steel wire mesh 2, the Class A insulation slurry 3 is away from the upper and lower sides of the vacuum insulation panel 1, and the outer protective layer 5 is bonded to the outside of the mesh cloth 4.

[0022] The steel mesh 2 significantly improves the overall mechanical strength of the insulation panel, making it less susceptible to damage from external pressure or impact, thereby enhancing its durability and resistance to damage. By attaching the steel mesh 2 around the perimeter of the vacuum insulation panel 1, the adhesion between subsequent materials such as insulation slurry and mesh cloth is enhanced, ensuring a tight bond between the various layers and improving the stability of the entire insulation system.

[0023] The connecting ear plate 6 serves as a connector between the insulation board and the building wall. It can fix the insulation board to the wall through bolts, rivets or other fixing methods to ensure that the insulation board will not fall off due to external environmental factors such as wind pressure, snow accumulation, etc.

[0024] The vacuum insulation panel 1 comprises a barrier film, a core material, and a gas adsorbent. The core material is located within the barrier film, and the gas adsorbent is applied to the surface of the core material. The barrier film maintains an internal vacuum state within the vacuum insulation panel 1, significantly reducing heat conduction and providing excellent insulation performance. The gas adsorbent applied to the core material absorbs gases that may leak into the vacuum layer, maintaining a high internal vacuum and preventing a decrease in insulation performance due to vacuum failure.

[0025] The core material is glass fiber, silica aerogel or microporous polyurethane. Glass fiber has high mechanical strength and can provide good support to prevent the vacuum layer from deforming when subjected to external force; it has good temperature resistance and is suitable for a wide temperature range. Due to its unique nanostructure, silica aerogel has extremely low thermal conductivity and can provide better insulation than other materials; silica aerogel is very light, which makes it more convenient to install and reduces the load on the building; aerogels are environmentally friendly materials because they can be produced from renewable resources and have a long service life. Compared with glass fiber and silica aerogel, microporous polyurethane has a certain flexibility and can better adapt to uneven surfaces; polyurethane is easy to process into different shapes and sizes and is suitable for various complex application scenarios; polyurethane foam has good sound insulation properties and can provide both thermal insulation and sound insulation effects.

[0026] A reinforcement layer is provided between the Class A insulation slurry 3 and the mesh cloth 4. The reinforcement layer can be made of composite materials such as carbon fiber or glass fiber. These materials have a high strength-to-weight ratio and can effectively enhance the rigidity of the structure. Alternatively, a high-strength non-woven fabric can be used as the reinforcement layer, providing additional mechanical strength and good air permeability.

[0027] The mesh 4 is alkali-resistant. It has excellent alkali resistance and maintains good performance in alkaline environments, resisting degradation or loss of strength due to contact with alkaline materials such as concrete. This is particularly important for meshes exposed to long-term building exterior wall environments. It also has high tensile strength and elongation at break, effectively enhancing the structural strength of the insulation system and preventing cracking and shedding.

[0028] The outer protective layer 5 is made of a weather-resistant material. Weather-resistant materials can withstand various environmental factors, such as ultraviolet rays, rain, and wind and sand erosion, ensuring that the outer protective layer remains in good condition over time, extending the service life of the entire building exterior wall insulation system. Using a weather-resistant coating as the outer protective layer 4 provides waterproofing and UV protection while enhancing aesthetics.

[0029] A waterproof layer is also included, which is arranged outside the outer protective layer 5. The waterproof layer can effectively prevent moisture from penetrating into the interior of the wall, avoid moisture in the wall caused by rain or other water sources, and thus reduce the risk of mildew and rot inside the wall.

[0030] The insulation board is provided with a protrusion 71 and an insertion part 72 at the top and bottom, respectively. The protrusion 71 and the insertion part 72 are of the same shape. The consistent shape only requires aligning the protrusion and the insertion part, and the splicing can be completed quickly, which simplifies the installation process and improves construction efficiency.

[0031] To further enhance the insulation board's strength, a rubber or silicone seal can be added between the protrusion 71 and the insertion portion 72. This not only enhances the insulation board's sealing properties, preventing water vapor penetration, but also increases the impact resistance and stability of the joint. Applying waterproof sealant to the joints improves the insulation board's waterproof properties and strengthens the tightness of the joints, preventing cold bridges.

[0032] The insulation board is provided with a guide groove which can effectively guide rainwater to flow along the edge of the insulation board, preventing moisture from penetrating into the wall through the joints between the insulation boards, thereby improving the waterproof performance of the insulation board and protecting the wall from moisture erosion.

[0033] During use, align the protrusions 71 of the upper and lower insulation boards with the insertions 72, apply waterproof sealant to the joints, and then secure the connecting lugs 6 on the sides of the insulation boards. It is worth noting that when all four sides of the insulation boards need to be spliced ​​together, the protrusions 71 and insertions 72 are positioned correctly, and the center insulation board is not provided with connecting lugs 6, while the insulation boards at the edges are provided with connecting lugs 6.

[0034] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
