Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically a novel thermally broken aluminum alloy door and window structure. Background Technology

[0002] Thermally broken aluminum alloy doors and windows are a common type of doors and windows in the construction industry. They use aluminum alloy profiles as the main frame and block heat transfer by setting thermal break structures in the profiles. They combine aesthetics, practicality and a certain degree of energy saving. They are widely used in residential and commercial buildings and are mainly used to achieve lighting, ventilation and isolation between indoor and outdoor environments. However, there are still some problems with the thermally broken aluminum alloy doors and windows on the market. The insulation layer in the existing door and window structure is not continuous and does not form a coaxial channel, resulting in poor thermal insulation effect, obvious heat transfer between indoor and outdoor, and condensation is easily generated in the cavity when the temperature difference is large, which corrodes the profile. This increases building energy consumption and shortens the service life of doors and windows, making it difficult to meet the modern building's demand for high efficiency, energy saving and long-term durability. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] like Figure 1 The novel thermally broken aluminum alloy door and window structure shown includes a fixed frame 1 and a glass frame 2 disposed inside it. The window frame 3 is hinged to the glass frame 2 by a hinge. The window frame 3 includes a main frame part 301 that contacts the fixed frame 1, a sub-frame part 302 at the top of the main frame part 301, and a glass part 303 at the top of the sub-frame part 302.

[0015] The bottom of the main frame 301 is provided with a reinforcing rib, and at least six cavities are provided along the width direction.

[0016] Among them, the reinforcing rib extends continuously along the length of the main frame 301 and is integrally formed with the main frame 301. It can significantly enhance the bending and deformation resistance of the bottom of the main frame 301, effectively resist the impact of external forces when the doors and windows are opened and closed, as well as the action of outdoor wind pressure, and prevent the bottom of the main frame 301 from being dented or bent.

[0017] Secondly, the multi-cavity structure can significantly reduce the overall weight of the main frame 301 while ensuring the structural strength of the main frame 301, and reduce the rotational load of the window frame 3, making the opening and closing of doors and windows easier and less strenuous. On the other hand, the partition structure formed between adjacent cavities can effectively block the sound transmission path, improve the sound insulation performance of the main frame 301, reduce the transmission of outdoor traffic noise, crowd noise and other noise into the room, and improve the indoor acoustic environment.

[0018] The sub-frame portion 302 is L-shaped, and a screen portion 304 is provided at the top of the horizontal plate of the sub-frame portion 302.

[0019] The screen window section 304 is a groove structure opened at the top of the horizontal plate. The width and depth of the groove are designed according to the size of commonly used screen windows. The screen window can be installed in the screen window section 304 by conventional fixing methods such as buckles and screws.

[0020] The third cavity of the main frame 301, the second cavity of the sub-frame 302, and the second cavity of the glass 303 are coaxial in the plumb direction, and a heat insulation layer 305 is filled in the third cavity of the main frame 301, the second cavity of the sub-frame 302, and the second cavity of the glass 303.

[0021] The third cavity of the main frame 301, the second cavity of the sub-frame 302, and the second cavity of the glass part 303 are provided with a set of symmetrically arranged and arc-shaped connecting plates 306 in the vertical direction. Multiple ventilation holes are opened in the connecting plate 306 between the main frame 301 and the sub-frame 302, and multiple ventilation holes are opened in the connecting plate 306 between the sub-frame 302 and the glass part 303. A heat insulation layer 305 is filled between the connecting plates 306.

[0022] The connecting plate 306 is made of high-strength aluminum alloy. Its arc-shaped structure design can disperse the stress inside the cavity, enhance the deformation resistance of the connecting plate 306 itself, and prevent the connecting plate 306 from breaking due to temperature changes or external forces during long-term use. Secondly, multiple ventilation holes are provided in the connecting plate 306 between the main frame 301 and the sub-frame 302. These ventilation holes are evenly distributed, and the hole diameter is designed according to the cavity size and ventilation requirements. Under the premise of ensuring the structural strength of the connecting plate 306, a small amount of air exchange between the cavity and the outside can be realized, effectively balancing the air pressure and temperature inside and outside the cavity, avoiding condensation caused by excessive temperature difference between the inside and outside of the cavity, preventing condensation from corroding the internal structure of the cavity, and extending the service life of the doors and windows.

[0023] The heat insulation layer 305 consists of recycled polyester fiber cotton, a flame-retardant polyurethane layer, and a nanoporous aerogel felt from the inside out.

[0024] The inner layer of recycled polyester fiber cotton has excellent thermal insulation and breathability, which can initially block the transfer of heat between indoors and outdoors. It is also environmentally friendly, as it can be made from recycled materials, which is in line with the concept of green building. The middle layer of flame-retardant polyurethane not only has an extremely low thermal conductivity, which can further enhance the thermal insulation effect, but also has excellent flame-retardant properties. It is not easy to burn when exposed to open flames, and produces less toxic gas when burning, which can significantly improve the fire safety of the door and window structure and meet the fire protection design requirements of the building. The outer layer of nanoporous aerogel felt is a new type of thermal insulation material with extremely low thermal conductivity. Its internal nanoporous structure can effectively suppress air convection and heat radiation, and minimize heat transfer. At the same time, the nanoporous aerogel felt is lightweight and thin, and will not add extra weight to the window frame 3, ensuring that the flexibility of opening and closing the door and window is not affected.

[0025] In actual installation and use, the fixed frame 1 is fixed to the reserved opening in the building wall by expansion bolts and other connectors. The glass frame 2 and the fixed frame 1 are sealed with sealing strips to ensure the airtightness of the connection between the door / window and the wall. Glass of the corresponding size is installed inside the glass frame 2, and the glass and the glass part 303 are bonded together with sealing strips to further improve the waterproof sealing performance.

[0026] When the doors and windows are closed, the contact surfaces of the main frame 301 and the fixed frame 1 are tightly fitted, achieving a primary seal with the sealing strip to prevent rainwater and airflow from seeping in. The insulation layer 305, through the continuous coaxial cavity and the filling between the connecting plate 306, forms a complete thermal barrier from the main frame 301 to the glass 303, effectively blocking the transfer of high or low outdoor temperatures to the interior. In summer, it reduces the amount of outdoor heat entering the interior, lowering air conditioning energy consumption; in winter, it reduces the amount of indoor heat loss, lowering heating energy consumption, thus meeting building energy conservation requirements. When ventilation is needed, the window frame 3 is rotated to open the doors and windows. The screen in the screen section 304 automatically functions to prevent mosquitoes and insects, while the ventilation holes on the connecting plate 306 balance the temperature and air pressure inside and outside the cavity, preventing condensation.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
