Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermally broken aluminum doors and windows, specifically relating to a high-performance aluminum-wood composite door and window with good thermal insulation and sealing properties. Background Technology
[0002] In the field of modern architecture, doors and windows are not only an important component of buildings but also a crucial element in achieving building energy conservation. Especially in regions with variable climates, the thermal insulation, heat preservation, and sealing performance of doors and windows directly impact indoor comfort and energy consumption levels. Aluminum-wood composite doors and windows, as a high-performance product, combine the durability of aluminum alloy with the natural beauty of wood. Furthermore, through rational structural design, they can significantly improve thermal insulation, heat preservation, and sealing performance, thus attracting widespread attention.
[0003] Currently, most aluminum-wood composite doors and windows on the market use a single thermal break strip design, which has limited thermal insulation performance and heat preservation effect, making it difficult to meet the higher energy-saving requirements of high-performance buildings. Furthermore, traditional sealing strips are mostly made of a single material, which cannot balance flexibility and hardness, easily leading to poor sealing and affecting the sound insulation and airtightness of the doors and windows. At the same time, the traditional straight-line structural design at the connection points of doors and windows lacks stability and may experience a decline in sealing performance over long-term use. Therefore, there is an urgent need for an improved aluminum-wood composite door and window structure that can comprehensively optimize thermal insulation, heat preservation, and sealing performance to meet the demands of modern buildings for high-performance door and window products.
[0004] An existing outward-opening composite window with an internal molding (Publication No.: CN201539189U) has the following inconveniences in the prior art aluminum-wood composite doors and windows:
[0005] 1. Limited thermal insulation performance: Traditional aluminum-wood composite doors and windows usually adopt a single thermal insulation strip design, and the thermal insulation strip is mostly a single cavity structure. Its thermal insulation effect cannot be fully utilized, making it difficult to meet the energy-saving requirements of high-performance buildings for doors and windows. Especially under extreme climatic conditions, when the temperature difference between indoors and outdoors is large, the thermal insulation performance is insufficient. Therefore, there is an urgent need for a high-performance aluminum-wood composite door and window with good thermal insulation.
[0006] 2. Poor sealing performance: Traditional door and window sealing strips often use a single material (such as ordinary rubber), which makes it difficult to balance flexibility and hardness, and is prone to a decline in sealing performance due to material fatigue. At the same time, gaps often exist when the sealing strip fills the sealing joints, making it difficult to achieve a complete seal, resulting in air leakage and poor sound insulation. Therefore, there is an urgent need for a high-performance aluminum-wood composite door and window with good sealing performance.
[0007] 3. Weak connection stability: The connection parts of doors and windows mostly adopt straight or simple overlapping structures. Under external force or after long-term use, they are prone to loosening or deformation, which further reduces the air tightness and water tightness of doors and windows. Therefore, there is an urgent need for a high-performance aluminum-wood composite door and window with high connection stability. Utility Model Content
[0008] The main purpose of this utility model is to provide a high-performance aluminum-wood composite door and window with good heat insulation, heat preservation and sealing performance, which can effectively solve the problems in the background art.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-performance aluminum-wood composite door and window with good thermal insulation and sealing properties, comprising aluminum profile one, aluminum profile two, aluminum profile three, and aluminum profile four. A serrated composite groove is provided at the lower end of each aluminum profile, and the serrated composite groove is connected to a PA66 nylon thermal insulation strip one. The lower end of the PA66 nylon thermal insulation strip is connected to the serrated composite groove of aluminum profile two. The upper end of aluminum profile one is snapped into connecting profile one through the serrated composite groove. The upper end of connecting profile one is connected to an eco-friendly... The lower end of the eco-wood is inserted into the serrated composite groove of aluminum profile four. The lower end of aluminum profile four is inserted into PA66 nylon thermal insulation strip two through the serrated composite groove. The other end of PA66 nylon thermal insulation strip two is inserted into the serrated composite groove at the upper end of aluminum profile three. A sealing strip connects aluminum profile three and aluminum profile two. A connector is provided on the right side of aluminum profile three to fix the glass. An aluminum-lined buckle is connected to aluminum profile four. The aluminum-lined buckle is connected to aluminum profile two through a connecting buckle. The lower end of the aluminum-lined buckle is fixed to the glass through a connector.
[0010] The PA66 nylon thermal insulation strip 1 is filled with polyurethane filler, and the PA66 nylon thermal insulation strip 2 is filled with polyurethane filler.
[0011] Furthermore, aluminum profile one, aluminum profile two, aluminum profile three and aluminum profile four are made of 1.8mm thick thermally broken aluminum material.
[0012] Furthermore, the inner wall of the serrated composite groove is provided with downward-sloping serrations, and the serrated composite groove is pressed into shape after the component to be snapped in is placed in it.
[0013] Furthermore, the first PA66 nylon thermal insulation strip is a 48mm multi-cavity nylon thermal insulation strip, and the second PA66 nylon thermal insulation strip is a 48mm multi-cavity reinforced nylon thermal insulation strip.
[0014] Furthermore, the sealing strip is a closed-type soft-hard composite sealing strip, and the wide-face sealing strip is a closed-type soft-hard composite wide-face sealing strip.
[0015] Furthermore, the aluminum-lined buckle is connected using a tenon and mortise structure, and the connecting buckle is connected using an insert-type connecting profile.
[0016] This utility model has the following beneficial effects:
[0017] 1. By designing PA66 nylon thermal insulation strip one and PA66 nylon thermal insulation strip two as a multi-cavity structure, and filling the space between them with polyurethane filler, the thermal insulation and sound insulation properties can be enhanced by utilizing the cavities and the polyurethane filler, resulting in the following benefits: Enhanced thermal insulation: The multi-cavity structure provides a more efficient thermal barrier effect. The cavities effectively reduce heat conduction paths, significantly reducing heat exchange between indoors and outdoors. The polyurethane filler has excellent thermal insulation properties, further filling the cavities and blocking heat conduction, thus achieving multiple insulation effects and meeting the energy-saving needs of extremely cold regions. Improved sound insulation: The complex sound wave propagation path formed by the multi-cavity structure effectively attenuates sound wave energy, reducing the intrusion of external noise.
[0018] 2. By using closed-type, soft-hard composite EPDM rubber strips for both sealing strips and wide-face sealing strips, the connection points can be fully filled, increasing sealing performance and bringing the following benefits: Improved sealing performance: Closed-type design: The sealing strip adopts a closed structure, which can completely fit the connection points of doors and windows, eliminating the gap problems that are prone to occur in traditional sealing strips, significantly improving air tightness and water tightness, and effectively preventing the penetration of air and moisture. Soft-hard composite structure: Through the reasonable combination of soft and hard materials, the soft part can flexibly fit the connection surface, and is not prone to deformation leading to poor sealing, while the hard part provides support, ensuring that the sealing strip is stable and does not deform in the long term.
[0019] 3. The serrated composite groove, with serrations at the internal connection points, embeds itself into the nylon and solid wood components during pressing, enhancing connection stability and sealing. This provides the following benefits: Enhanced Connection Stability: The serrated embedding structure creates a mechanical interlocking structure, stronger than traditional smooth connections, preventing loosening or detachment over time. Anti-slip and Anti-displacement: The serrated design increases friction on the connection surfaces, effectively preventing displacement or separation due to external forces or temperature / humidity changes, further improving the overall stability of the door and window structure. Improved Sealing Performance: Multiple Embedded Contacts: The serrated structure creates multiple points of contact and embedding during connection, effectively filling gaps that easily occur in traditional planar contacts, significantly improving the sealing effect and preventing air, moisture, or dust from seeping in through the connection. Tight Fit: The precise structure of the serrations ensures a tighter fit between the nylon and solid wood materials, enhancing airtightness and watertightness at the connection, meeting the stringent sealing requirements of high-performance doors and windows.
