Description

Technical Field

[0001] This application relates to the technical field of aluminum alloy doors and windows, and in particular to a multi-layer sealing structure for aluminum alloy doors and windows. Background Technology

[0002] With increasing awareness of energy conservation and environmental protection, and increasingly stringent requirements for living environment quality, building energy conservation has gradually become a hot topic of social concern. In this process, doors and windows, as a core component of the building envelope, play an extremely important role. Doors and windows not only bridge indoor and outdoor air circulation, lighting, and ventilation, but also play a crucial role in temperature regulation. In cold winters, the thermal insulation performance of doors and windows effectively prevents indoor heat loss, while in hot summers, good thermal insulation effectively blocks high external temperatures, maintains a comfortable indoor temperature, reduces the frequency of air conditioning and heating use, and lowers energy consumption.

[0003] Traditional door and window materials and structures often fall short in terms of thermal insulation, especially in extremely cold or hot climates, where the sealing, insulation, and heat preservation properties of doors and windows directly impact a building's energy efficiency. Therefore, with the continuous development of building technology, more and more innovative materials and technologies are being applied to the design and manufacture of doors and windows. Modern energy-saving doors and windows not only effectively reduce indoor temperature fluctuations but also utilize intelligent control systems to regulate window opening and closing, thereby automatically regulating the indoor environment, further saving energy and improving living comfort. With the promotion of green building concepts, more and more buildings are beginning to use environmentally friendly, recyclable door and window materials, reducing resource waste and mitigating the environmental impact throughout the building's lifecycle.

[0004] While aluminum alloy doors and windows commonly found on the market are aesthetically pleasing and easy to maintain, their sealing performance often falls short of ideal levels. This can easily lead to heat loss in winter and cold air leakage in summer, thereby increasing the cost of air conditioning and heating, which is inconsistent with modern green building design concepts. Utility Model Content

[0005] In order to optimize the problems of heat loss in winter and cold air leakage in summer that are prone to occur in aluminum alloy doors and windows, thereby increasing the cost of air conditioning and heating, which is not in line with the modern green building design concept, this application provides a multi-layer sealing structure for aluminum alloy doors and windows.

[0006] This application provides a multi-layer sealing structure for aluminum alloy doors and windows, which adopts the following technical solution: A multi-layer sealing structure for aluminum alloy doors and windows includes a main window frame, a sealing frame fixedly connected to the outer surface of the main window frame, an inner sealing strip fixedly connected to the outer surface of the main window frame, an outer sealing strip fixedly connected to the outer surface of the sealing frame on the same side as the inner sealing strip, a pressing block fixedly connected to the outer surface of the main window frame next to the inner sealing strip, a V-shaped rubber strip fixedly connected to the outer surface of the main window frame corresponding to the pressing block, and a high-molecular polyurethane sealant applied to the contact surface between the pressing block and the main window frame.

[0007] By adopting the above technical solution, this utility model provides a multi-layer sealing structure, which consists of several layers with different functional characteristics complementing each other to form an overall protective system. This mainly includes, but is not limited to, an inner sealing strip and an outer sealing strip. Two soft sponge sealing strips made of PVC material are placed on the inner and outer sides, located outside the main window frame or sealing frame. A discontinuously distributed compression block with a V-shaped cross-section made of EPDM rubber is placed in the middle of the main window frame and embedded in the groove of the main window frame. The innermost layer is coated with a professional sealant of high-polymer polyurethane, which is environmentally friendly, waterproof, mildew-proof, weather-resistant, and has excellent adhesion, forming a comprehensive protective barrier. These components, through precise matching, achieve multi-layered, all-round, three-dimensional coverage, ensuring that any possible tiny gaps are completely sealed without leaving any blind spots.

[0008] In a preferred embodiment, a buffer pad is fixedly connected to the inner surface of the main window frame corresponding to the sealing frame, and the buffer pad is made of fluororubber.

[0009] By adopting the above technical solution, buffer gaskets are inserted into the grooves of the main window frame and sealing frame, effectively creating an air buffer layer within the main window frame, sealing frame, and buffer gaskets. The buffer gaskets are made of fluororubber, which is soft and flexible, allowing it to adapt to sealing applications with complex shapes. Especially in areas requiring good sealing performance, such as doors, windows, and mechanical equipment, it provides effective sealing performance. Its softness also helps reduce deformation or stress concentration caused by temperature changes, pressure fluctuations, or external forces, improving the lifespan and stability of the sealing material, as well as its corrosion resistance. Furthermore, it effectively reduces noise when walls and doors / windows vibrate.

[0010] In a preferred embodiment, a water guide groove is provided on the outer surface of the buffer pad, and a reference frame is fixedly connected to the inner surface of the buffer pad.

[0011] By adopting the above technical solution, the buffer pad is equipped with a water guide groove on the outside, which works together with the V-shaped rubber strip to prevent rainwater from seeping in. The reference frame is harder than the buffer pad, which facilitates the fixing of the pressure frame and also facilitates the installation of polymer polyurethane sealant.

[0012] In a preferred embodiment, an S-shaped deformation strip is fixedly connected to the outer surface of the reference frame, and the S-shaped deformation strip is made of polymer foam material.

[0013] By adopting the above technical solution, the S-shaped deformation strip, the stress frame, and the pressure frame are positioned in the middle of the V-shaped rubber strip and the buffer pad. The space inside the corresponding main window frame is in a vacuum state, thereby achieving a better heat insulation effect with less contact medium. Similarly, the S-shaped deformation strip adopts an S shape.

[0014] In a preferred embodiment, a force-bearing frame is fixedly connected to the outer surface between the S-shaped deformation strips, and the force-bearing frame is made of carbon fiber.

[0015] By employing the aforementioned technical solutions and combining them with a multi-layered load-bearing frame, carbon fiber exhibits excellent high toughness and durability. As an advanced composite material, carbon fiber not only possesses extremely high strength and rigidity but also maintains a certain degree of flexibility and moderate deformation capacity under external forces. This allows it to effectively absorb impacts and vibrations in structural applications, providing a good cushioning effect and thus reducing the impact of external loads on the frame. Due to the lightweight nature of carbon fiber, it can significantly reduce the overall weight of the frame while ensuring strength and stability, enhancing the overall structural operability and adaptability.

[0016] In a preferred embodiment, a pressure-bearing frame is fixedly connected to the outer surface of the reference frame corresponding to the S-shaped deformation strip, and the pressure-bearing frame is sealed with the V-shaped rubber strips on both sides, the reference frame, and the main window frame.

[0017] By employing the aforementioned technical solutions, the S-shaped deformation strips, load-bearing frames, and compression frames, along with the main window frame, utilize their precise design and material properties to create a vacuum state within the space, completely isolating it from external heat conduction paths. The excellent insulation effect of the vacuum layer significantly reduces heat exchange, allowing the windows to effectively block high-temperature heat from entering the room in summer and reduce heat loss in winter, thereby improving the building's energy efficiency and living comfort. The excellent gas sealing in a vacuum state prevents air convection and heat conduction, a key factor in achieving highly efficient thermal insulation.

[0018] In a preferred embodiment, the inner surface of the main window frame is provided with a placement groove, and tempered glass is fixedly connected to the inner surface of the placement groove.

[0019] By adopting the above technical solution, the placement groove, serving as a reference position, plays a crucial role in aluminum alloy door and window systems, especially during the installation of tempered glass. This groove design ensures precise positioning and stable support for the glass during installation, providing the necessary support structure for the entire door and window frame, ensuring both stability and safety during use. Through the reference position of the placement groove, tempered glass can be quickly and accurately placed in the predetermined position, avoiding errors or misalignment during installation. A vacuum process is required in the middle of the placement groove, a crucial step in aluminum alloy door and window systems, particularly in improving sound insulation and noise reduction. By effectively removing air from the placement groove, the path of noise transmission in the air is reduced, thus significantly improving the sound insulation performance of the doors and windows.

[0020] In a preferred embodiment, an auxiliary frame is provided on the outer surface of the main window frame, and the size of the auxiliary frame is consistent with that of the buffer pad.

[0021] By adopting the above technical solution, the auxiliary frame in this application is mainly used to help understand the design concept and functional layout of the door and window structure. While theoretically the auxiliary frame plays a supporting and positioning role, in actual operation, due to differences in manufacturing processes, materials, or installation environment, the positions of the multi-layer seals may deviate to some extent. However, despite this deviation, the final sealing effect can still be guaranteed. Even if some sealing layers deviate slightly, as long as they can contact the outer surface of the buffer gasket, the sealing performance will not be significantly affected. The buffer gasket, as a key component, will form a tight contact with the contact surface of the multi-layer seals, ensuring the complete sealing of the door and window structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model provides a multi-layer sealing structure, which consists of several layers with different functional characteristics complementing each other to form an overall protective system. It mainly includes, but is not limited to, an inner sealing strip and an outer sealing strip. Two soft sponge sealing strips made of PVC material are placed on the inner and outer sides, located outside the main window frame or sealing frame. A discontinuously distributed compression block with a V-shaped cross-section made of EPDM rubber is placed in the middle of the main window frame and embedded in the groove of the main window frame. The innermost layer is coated with a professional sealant of high-polymer polyurethane, which is environmentally friendly, waterproof, mildew-proof, weather-resistant, and has excellent adhesion, forming a comprehensive protective barrier. These components, through precise matching, achieve multi-layered, all-round, three-dimensional coverage, ensuring that any possible tiny gaps are completely sealed without leaving any blind spots.

[0023] 2. Aluminum alloy doors and windows simultaneously insert buffer pads into the grooves of the main window frame and sealing frame, effectively creating an air buffer layer between the main window frame, sealing frame, and buffer pads. The buffer pads are made of fluororubber, which can effectively reduce noise when the wall and doors and windows vibrate. The S-shaped deformation strip, stress frame, and pressure frame are positioned in the middle of the V-shaped rubber strip and buffer pads, and the space created between them and the main window frame is in a vacuum state, thus achieving better heat insulation effect with less contact medium.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] See Figure 1-5 The following technical solution is adopted: a multi-layer sealing structure for aluminum alloy doors and windows, including a main window frame 1, a sealing frame 2 fixedly connected to the outer surface of the main window frame 1, an inner sealing strip 3 fixedly connected to the outer surface of the main window frame 1, an outer sealing strip 6 fixedly connected to the outer surface of the sealing frame 2 on the same side as the inner sealing strip 3, a pressing block 4 fixedly connected to the outer surface of the main window frame 1 next to the inner sealing strip 3, a V-shaped rubber strip 5 fixedly connected to the outer surface of the main window frame 1 corresponding to the pressing block 4, and a high-molecular polyurethane sealant applied to the contact surface of the pressing block 4 and the main window frame 1.

[0029] This invention provides a multi-layered sealing structure, which consists of several layers with different functional characteristics complementing each other to form an overall protective system. It mainly includes, but is not limited to, an inner sealing strip 3 and an outer sealing strip 6. Two soft sponge sealing strips made of PVC material are placed on the inner and outer sides, located outside the main window frame 1 or the sealing frame 2. A discontinuously distributed, V-shaped compression block 4 made of EPDM rubber is embedded in the groove of the main window frame 1. The innermost layer is coated with a high-polymer polyurethane-based environmentally friendly, waterproof, mildew-proof, weather-resistant, and highly adhesive professional sealant to form a comprehensive protective barrier. These components, through precise matching, achieve multi-layered, all-round, three-dimensional coverage, ensuring that any possible tiny gaps are completely sealed without leaving any blind spots.

[0030] See Figure 1-3 The main window frame 1 is fixedly connected to the inner surface of the sealing frame 2 with a buffer pad 7, which is made of fluororubber.

[0031] A buffer gasket 7 is inserted into the grooves of the main window frame 1 and the sealing frame 2, effectively creating an air buffer layer within the main window frame 1, the sealing frame 2, and the buffer gasket 7. The buffer gasket 7 is made of fluororubber, which is soft and flexible, allowing it to adapt to sealing applications with complex shapes. It provides effective sealing performance, especially in areas requiring a good seal, such as doors, windows, and mechanical equipment. Its softness also helps reduce deformation or stress concentration caused by temperature changes, pressure fluctuations, or external forces, improving the lifespan and stability of the sealing material. Its corrosion resistance and other properties also effectively reduce noise during wall and window vibrations.

[0032] See Figure 1-3 The outer surface of the buffer pad 7 is provided with a water guide groove 8, and the inner surface of the buffer pad 7 is fixedly connected with a reference frame 9.

[0033] The buffer pad 7 has a water guide groove 8 on the outside, which works together with the V-shaped rubber strip 5 to prevent rainwater from seeping in. The reference frame 9 is harder than the buffer pad 7, which makes it easier to fix the pressure frame 12 and also facilitates the installation of high-polymer polyurethane sealant.

[0034] See Figure 4-5 An S-shaped deformation strip 10 is fixedly connected to the outer surface of the reference frame 9. The S-shaped deformation strip 10 is made of high-polymer foam material.

[0035] The S-shaped deformation strip 10, the stress frame 11, and the pressure frame 12 are positioned between the V-shaped rubber strip 5 and the buffer pad 7. The space created by them and the main window frame 1 is in a vacuum state, thus achieving better heat insulation with less contact medium. Similarly, the S-shaped deformation strip 10 adopts an S-shape.

[0036] See Figure 4-5A force-bearing frame 11 is fixedly connected to the outer surface between the S-shaped deformation strips 10. The force-bearing frame 11 is made of carbon fiber.

[0037] Combined with a multi-layered load-bearing frame, carbon fiber exhibits excellent toughness and durability. As an advanced composite material, carbon fiber not only possesses extremely high strength and rigidity but also maintains a certain degree of flexibility and moderate deformation capacity under external forces. This allows it to effectively absorb impacts and vibrations in structural applications, providing excellent cushioning and reducing the impact of external loads on the frame. Due to its lightweight properties, carbon fiber can significantly reduce the overall weight of the frame while ensuring strength and stability, enhancing the overall structural operability and adaptability.

[0038] See Figure 4-5 The reference frame 9 is fixedly connected to the outer surface of one side of the S-shaped deformation strip 10 with a pressure frame 12. The pressure frame 12 is sealed with the V-shaped rubber strips 5 on both sides, the reference frame 9 and the main window frame 1.

[0039] The S-shaped deformation strip 10, the load-bearing frame 11, and the compression frame 12, corresponding to the main window frame 1, utilize their precise design and material properties to create a vacuum state inside the space, completely isolating the external heat conduction path. The excellent insulation effect of the vacuum layer can significantly reduce heat exchange, allowing the window to effectively block high-temperature heat from entering the room in summer and reduce heat loss in winter, thereby improving the building's energy efficiency and living comfort. The excellent gas sealing in the vacuum state can prevent air convection and heat conduction, which is a key factor in achieving high-efficiency thermal insulation.

[0040] See Figure 1-3 The inner surface of the main window frame 1 is provided with a placement groove 13, and tempered glass is fixedly connected to the inner surface of the placement groove 13.

[0041] The placement groove 13 serves as a reference position and plays a crucial role in aluminum alloy door and window systems, especially during the installation of tempered glass. This groove design ensures precise positioning and stable support for the glass during installation, providing the necessary support structure for the entire door and window frame, ensuring both stability and safety during use. Using the reference position of the placement groove 13, tempered glass can be quickly and accurately placed in the predetermined position, avoiding errors or misalignment during installation. A vacuum process is required within the placement groove 13, a crucial step in aluminum alloy door and window systems, particularly in improving sound insulation and noise reduction. By effectively removing air from the placement groove 13, the path of noise transmission in the air is reduced, significantly improving the sound insulation performance of the doors and windows.

[0042] See Figure 1-3An auxiliary frame 14 is provided on the outer surface of the main window frame 1, and the size of the auxiliary frame 14 is consistent with that of the buffer pad 7.

[0043] In this application, the auxiliary frame 14 is primarily used to aid in understanding the design concept and functional layout of the door and window structure. While theoretically the auxiliary frame 14 provides support and positioning, in actual operation, due to differences in manufacturing processes, materials, or the installation environment, the positions of the multi-layer seals may deviate to some extent. However, despite this deviation, the final sealing effect can still be guaranteed. Even if some sealing layers deviate slightly, as long as they can contact the outer surface of the buffer gasket 7, the sealing performance will not be significantly affected. The buffer gasket 7, as a key component, will form a tight contact with the contact surface of the multi-layer seals, ensuring the complete sealing of the door and window structure.

[0044] The implementation principle of the embodiments of the subject matter of this application is as follows: This utility model provides a multi-layer sealing structure, which consists of several layers with different functional characteristics complementing each other to form an overall protective system. It mainly includes, but is not limited to, an inner sealing strip 3 and an outer sealing strip 6. Two soft sponge sealing strips made of PVC material are placed on the inner and outer sides, located outside the main window frame 1 or the sealing frame 2. A discontinuously distributed compression block 4 made of V-shaped cross-section of EPDM rubber is set in the middle of the main window frame 1, embedded in a groove. An outer V-shaped rubber strip 5 protects the compression block 4, while the V-shaped groove facilitates the drainage of dust and rainwater, preventing it from entering deeper areas. The innermost layer is coated with a professional sealant of high-polymer polyurethane, which is environmentally friendly, waterproof, mildew-proof, weather-resistant, and has excellent adhesion, forming a comprehensive protective barrier. These components work together to achieve a multi-layered, all-around, three-dimensional wrapping and covering, ensuring that any possible tiny gaps are completely sealed without leaving any blind spots. The aluminum alloy doors and windows also have buffer pads 7 inserted into the grooves of the main window frame 1 and the sealing frame 2, which actually creates an air buffer layer in the main window frame 1, the sealing frame 2, and the buffer pads 7. The buffer pads 7 are made of fluororubber, which can effectively reduce noise when the walls and doors and windows vibrate. The water guide channel 8 is set on the outside and works with the V-shaped rubber strip 5 to prevent rainwater from seeping in. The S-shaped deformation strip 10, the stress frame 11, and the pressure frame 12 are located in the middle of the V-shaped rubber strip 5 and the buffer pads 7. The space inside the main window frame 1 is in a vacuum state, thus achieving better heat insulation effect with less contact medium. Similarly, the S-shaped deformation strip 10 adopts an S-shape and works with the multi-layered stress frame 11 frame to undergo slight deformation for buffering. The auxiliary frame 14 in this application is only for illustrative purposes. In actual operation, the position of the multi-layered seal will deviate, but they will all actually contact the outer surface of the buffer pads 7.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
