Description

Technical Field

[0001] This application relates to the field of curtain wall panel technology, and more specifically, to a thermally insulated composite curtain wall panel. Background Technology

[0002] As modern architecture develops towards higher heights, larger scales, and greater complexity, curtain walls, as a crucial component of building envelopes, not only fulfill functions such as enclosure, insulation, heat insulation, and sound insulation, but also largely determine the overall aesthetics and artistic expression of a building. Composite curtain wall panels, due to their multi-functionality and relatively convenient construction, have been widely used in modern buildings. Traditional composite curtain wall panels typically consist of a panel and an inner lining material, with common structures including metal panels combined with insulation materials such as polystyrene or polyurethane foam. However, many existing composite curtain wall panels have gradually revealed some shortcomings in practical applications. First, the structural strength of the curtain wall panels is insufficient, making it difficult to meet the mechanical performance requirements of high-rise buildings for wind pressure resistance and impact resistance, posing safety hazards. Second, in terms of sound insulation, heat insulation, thermal insulation performance, and ease of installation, existing curtain wall panels often fall short of expectations. Utility Model Content

[0003] To overcome the above deficiencies, this application provides a thermally insulated composite curtain wall panel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A thermally insulated composite curtain wall panel includes a curtain wall panel frame, characterized in that: a composite curtain wall panel is integrally die-cast inside the curtain wall panel frame, the composite curtain wall panel is composed of a panel, a sound insulation board, a heat insulation board, a thermal insulation board and a reinforcing mesh, the reinforcing mesh is placed inside the panel, the sound insulation board, the heat insulation board and the thermal insulation board and is fixedly connected to each other, and an assembly component is installed on the back of the composite curtain wall panel, the assembly component is fixedly connected to the external keel.

[0006] Furthermore, the panel is typically made of aluminum and coated with fluorocarbon paint.

[0007] Furthermore, the sound insulation panel is made of metal with a honeycomb core layer consisting of hexagonal sealed cells, and an adhesive is provided between the core and the panel.

[0008] Furthermore, the heat insulation board is usually made of magnesium oxide board, and an adhesive is provided between it and the sound insulation board.

[0009] Furthermore, the insulation board is made of high-performance materials such as polyurethane, and has a reflective coating and air layer design. An adhesive is provided between the insulation board and the heat insulation board, and a back panel layer of the same material as the curtain wall frame is provided on the back.

[0010] Furthermore, the reinforcing mesh is coiled in a serpentine shape and is die-cast inside the panel, the sound insulation board, the heat insulation board, and the thermal insulation board.

[0011] Furthermore, the assembly component includes four locking blocks and four locking bolts. The four locking blocks are integrally placed at the four corners of the back plate of the insulation board and integrally formed with the four corner extension rods of the reinforcing mesh. The four locking bolts are fixedly connected to the external keel through the four locking blocks.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model of curtain wall panel ingeniously integrates multiple functions such as sound insulation, heat insulation, thermal insulation, and decoration. The panel provides aesthetic protection, the sound insulation board effectively blocks noise, the heat insulation board blocks heat conduction, and the thermal insulation board (in conjunction with a reflective coating and an air layer) significantly reduces heat loss or intrusion, achieving a comprehensive improvement in the performance of the building envelope system. The use of a metal honeycomb core structure as the sound insulation board, with its hexagonal sealed cell structure, effectively absorbs and blocks sound wave propagation, significantly improving the sound insulation performance of the curtain wall and creating a quieter and more comfortable indoor environment. The combination of the heat insulation board (magnesium oxide board) and the thermal insulation board (high-performance materials such as polyurethane), especially the reflective coating and air layer design on the thermal insulation board, greatly reduces the thermal conductivity coefficient, effectively preventing outdoor heat transfer in summer and indoor heat loss in winter, significantly reducing building energy consumption and improving indoor thermal comfort.

[0014] 2. The reinforcing mesh of this utility model adopts a serpentine design and is integrally die-cast inside the panel, sound insulation board, heat insulation board, and thermal insulation board, forming a solid overall structure. This design not only enhances the overall bending, shearing, and impact resistance of the panels, meeting the high mechanical performance requirements of exterior wall panels in high-rise buildings, but also effectively prevents delamination or misalignment between functional layers, improving the reliability and durability of the product.

[0015] 3. The assembly components of this utility model are ingeniously designed. Four locking blocks are integrated at the four corners of the back plate, which, together with the locking bolts, can be quickly and securely connected to the external keel. This design simplifies the installation process, reduces the complexity of on-site operations and the number of required connectors, improves installation efficiency, and reduces labor costs and the risk of installation errors.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] Example:

[0023] Please see Figure 1 , Figure 3 A thermally insulated composite curtain wall panel includes a curtain wall panel frame 1, which is made of aluminum alloy profiles. The internal space of the frame is slightly larger than the size of the composite curtain wall panel 2, used to accommodate and support the composite curtain wall panel 2. The edges of the frame are provided with reinforcing ribs to improve the overall rigidity of the frame.

[0024] Please see Figure 1 , Figure 2 , Figure 3 A heat-insulating composite curtain wall panel includes a curtain wall panel frame 1 with a composite curtain wall panel 2 integrally die-cast inside. The composite curtain wall panel 2 is composed of a panel 21, a sound insulation board 22, a heat insulation board 23, a thermal insulation board 24, and a reinforcing mesh 25. The panel 21, the sound insulation board 22, the heat insulation board 23, and the thermal insulation board 24 are provided with reinforcing mesh 25 and are fixedly connected to each other. An assembly component 3 is installed on the back of the composite curtain wall panel 2 and is fixedly connected to the external keel. The assembly component 3 includes four clips 31 and four locking bolts 32.

[0025] The composite curtain wall panel 2 is manufactured using an integrated die-casting process combined with interlayer adhesive, and its dimensions match the internal space of the curtain wall frame 1. This composite curtain wall panel consists of a multi-layer structure. The surface of panel 21 is treated with fluorocarbon paint, with colors selectable from classic silver-gray or other design-specified colors. The fluorocarbon paint layer not only provides excellent weather resistance and corrosion resistance but also ensures long-term aesthetic appeal. A waterproof layer is also applied for waterproofing. The sound insulation panel 22 uses a metal honeycomb panel. Its core is a metal honeycomb core layer composed of numerous regular hexagonal closed cells. This structure effectively absorbs and reflects sound waves, providing excellent sound insulation performance. The sound insulation panel 22 is evenly coated and firmly bonded to the inside of panel 21 using a specialized high-performance structural adhesive. The heat insulation panel 23 uses a 5mm thick magnesium oxide board. Magnesium oxide board is lightweight, high-strength, and has excellent fire resistance, while also providing a certain degree of heat insulation. The insulation board 23 is also bonded to the inside of the sound insulation board 22 using a special adhesive. The thermal insulation board 24 is made of rigid polyurethane foam (PUR) board, a high-performance thermal insulation material with extremely low thermal conductivity. To further improve the thermal insulation effect, the outer surface of the PUR board facing the interior is coated with a layer of highly reflective aluminum foil or a reflective coating. An air layer is formed inside the PUR board through a special structural design, such as through opening or a specific foaming process, utilizing the low thermal conductivity of air to enhance the thermal insulation performance. The thermal insulation board 24 is bonded to the inside of the insulation board 23 using a special adhesive. In addition, the back of the insulation board 24 is provided with a back panel layer of the same material as the curtain wall frame 1, and the sidewalls of the back panel layer are heat-pressed to the curtain wall frame 1. This back panel layer not only increases the flatness and rigidity of the overall structure but also provides a foundation for subsequent component assembly. The reinforcing mesh 25 is made of serpentine metal. Before die casting, this reinforcing mesh 25 is precisely placed along a predetermined path inside the composite material consisting of panel 21, sound insulation board 22, heat insulation board 23, thermal insulation board 24, and back panel layer, typically located between or near the center of each layer. This design not only enhances the overall bending, shear, and impact resistance of the panel, meeting the high mechanical performance requirements of exterior wall panels in high-rise buildings, but also effectively prevents delamination or misalignment between functional layers.

[0026] The process involves precisely stacking the aforementioned panel 21, sound insulation board 22, heat insulation board 23, thermal insulation board 24, and their backing layer in sequence, and uniformly applying a special adhesive between adjacent layers. This ensures alignment, flatness, and the absence of air bubbles between each layer. Then, the coiled reinforcing mesh 25 is placed in the predetermined position. The entire assembled composite is carefully placed inside the aluminum alloy curtain wall panel frame 1. The entire mold, including the frame and composite, is placed in a die-casting machine, and die-cast using aluminum alloy or other specified die-casting material of the same material as the frame. This die-casting process not only firmly bonds all layers and the reinforcing mesh into a single unit but also completely encapsulates the reinforcing mesh, greatly enhancing the overall structural strength and deformation resistance of the composite curtain wall panel 2.

[0027] The assembly component 3 achieves a more stable and integrated installation connection. Four locking blocks 31 are precisely and integrally molded at the four corners of the back panel layer of the composite curtain wall panel 2 (i.e., the insulation board 24). Crucially, each locking block 31 is not independently manufactured and then simply fixed; instead, it is integrally molded with the reinforcing mesh 25 extending from the four corners. This means that the locking blocks 31 extend directly from the structure of the reinforcing mesh 25, becoming an inseparable whole with the back panel layer and the reinforcing mesh 25 during manufacturing, similar to die casting. The locking blocks 31 are designed as raised structures with mounting holes, such as L-shapes or blocks with reinforcing ribs, to ensure sufficient connection strength and stability. Four locking bolts 32 are standard parts to accommodate outdoor environments. The bolt size is selected based on the thickness of the keel and the required connection strength.

[0028] In this process, after the keel system of the building facade, such as the horizontal and vertical keel grid composed of angle steel or aluminum alloy profiles, is installed in place, the composite curtain wall panel 2 is aligned. The locking block 31 is then positioned on the keel, and four locking bolts 32 are sequentially passed through the mounting holes on the locking block 31, and then tightened to the keel. Because the locking block 31 and the panel itself are integrally formed, the force transmitted by this connection method acts directly on the core reinforcing structure of the panel, greatly improving the reliability of the connection and preventing the risk of loosening due to long-term wind loads or vibrations. This design simplifies the installation steps, reduces the need for additional welding or installation of connectors on-site, and improves installation efficiency and quality.

[0029] The working principle of this thermally insulated composite curtain wall panel is as follows: First, during the factory prefabrication stage, the composite curtain wall panel 2 is manufactured using a precise one-piece die-casting process. This process not only firmly combines the panel 21, sound insulation board 22, heat insulation board 23, thermal insulation board 24, and reinforcing mesh 25 into a whole, but also ensures that the materials of each layer are tightly bonded together by interlayer adhesive, forming a stable multi-functional structure. This structure is then precisely installed into the interior of the curtain wall panel frame 1, forming a complete unit. On the construction site, the installation process is efficient and simple. Operators first use the clips 31 on the assembly component 3 to initially position and connect the entire curtain wall panel unit to the keel on the main building structure. This step facilitates subsequent precise positioning. Next, by tightening the locking bolts 32, the clips 31 are firmly fixed to the keel, thus completing the final installation of the curtain wall panel unit. Once installed, the composite curtain wall panel 2 begins to perform its core functions. Its internal multi-layered structure works in tandem: panel 21 provides decoration and protection, sound insulation panel 22 effectively blocks external noise, and heat insulation panel 23 and thermal insulation panel 24 utilize low thermal conductivity materials and structural design to significantly reduce heat transfer between the building's interior and exterior. In this way, the curtain wall panel provides the building with excellent sound insulation, heat insulation, and thermal insulation performance, effectively improving the indoor thermal environment and reducing the building's energy consumption.

[0030] It should be noted that the specific model and specifications of the locking bolt 32 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0031] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
