Description

Technical Field

[0001] This utility model belongs to the field of thermally broken aluminum doors and windows, specifically relating to a thermally broken aluminum wood door and window with good thermal insulation properties. Background Technology

[0002] With the promotion of building energy conservation and green environmental protection concepts, the optimization of the thermal insulation, heat preservation, and sealing performance of doors and windows, as an important component of the building envelope, has become particularly important. Traditional aluminum alloy doors and windows, due to their high thermal conductivity and poor thermal insulation performance, are unable to meet the increasingly stringent energy-saving requirements. Although the emergence of thermally broken aluminum door and window technology has alleviated this problem to some extent, traditional thermally broken aluminum doors and windows still have shortcomings in sealing performance and resistance to thermal expansion and contraction, leading to problems such as sealing failure and reduced thermal insulation performance when used in extreme climatic conditions.

[0003] Existing thermally broken aluminum windows and doors typically use sealing strips made of a single material. Due to the lack of flexibility and adjustment, these strips are prone to aging or deterioration in sealing performance over long-term use due to thermal expansion and contraction. Simultaneously, the internal insulation structure of these windows and doors is relatively simple, failing to effectively address the issue of heat convection within the air layer, further reducing their thermal insulation performance. Furthermore, in terms of sound insulation, existing window and door structures do not fully utilize the sound-shielding effect of multi-cavity designs, resulting in less than ideal sound insulation performance.

[0004] To address the aforementioned issues, the market urgently needs high-performance aluminum-wood composite doors and windows that excel in sealing, thermal insulation, and sound insulation to meet building energy conservation requirements and enhance user comfort.

[0005] 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:

[0006] 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.

[0007] 2. Poor sealing performance: Due to the lack of sufficient space in the material and structural design of existing technology to adapt to temperature changes, the door and window frames and sealing strips will be affected by thermal expansion and contraction during long-term use, resulting in deformation, increased gaps, or even sealing failure. Therefore, there is an urgent need for a high-performance aluminum-wood composite door and window with good sealing performance. Utility Model Content

[0008] The main purpose of this utility model is to provide a thermally broken aluminum-wood door and window with good thermal insulation properties, 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 thermally broken aluminum-wood door and window with good thermal insulation properties, comprising aluminum material, a PA nylon thermal insulation strip snapped into the middle of the aluminum material, polyurethane filler filling the thermal insulation cavity formed between the aluminum material and the PA nylon thermal insulation strip, an equal pressure sealing strip set at the rear end of the front aluminum material, a PA nylon thermal insulation strip connected next to the equal pressure sealing strip, a wide sealing strip set at the upper end of the upper aluminum material, an opening sash snapped into the other end of the wide sealing strip, the other end of the opening sash snapped into the aluminum material, a soft and hard composite sealing strip snapped between the lower aluminum materials, an aluminum-lined buckle snapped into the upper right aluminum material, and an insulated glass unit set in the middle of the aluminum-lined buckle and the lower aluminum material, wherein the insulated glass unit can be connected by different buckles as needed;

[0010] The insulated glass is a triple-glazed, double-cavity insulated glass. The equal pressure sealing strip and the wide-face sealing strip are made of soft and hard co-extruded composite strips. The opening fan is made of eco-friendly wood, and the opening fan cavity is designed with a round hole.

[0011] Furthermore, the aluminum material is 1.8mm thick thermally broken aluminum material.

[0012] Furthermore, the aluminum-lined buckle is connected using a mortise and tenon structure.

[0013] Furthermore, the PA66 nylon thermal insulation strip is a 48mm multi-cavity nylon thermal insulation strip.

[0014] Furthermore, the upper right side aluminum material is connected to a fixing structure at its outer end.

[0015] Furthermore, the fixing structure has a slot inside, and the right end of the upper right aluminum material is fixed to the fixing structure through the slot.

[0016] This utility model has the following beneficial effects:

[0017] 1. The isobaric sealing strip and wide-face sealing strip adopt a closed-loop soft-hard co-extruded composite strip, with internal space reserved for thermal expansion and contraction. This reduces the impact of thermal expansion and contraction on its structure and brings the following benefits: Improved sealing performance: The closed-loop soft-hard co-extruded composite strip combines the structural stability of the hard part with the elastic sealing performance of the soft part, achieving a tighter seal and preventing air and moisture penetration. The isobaric design effectively balances the internal and external pressure difference, further improving sealing performance and preventing seal failure.

[0018] 2. The operable sash features two structural elements: a perforated interior and a polyurethane-filled insulating cavity. These elements enhance the thermal insulation, sound insulation, and heat insulation properties of the composite door and window, offering the following benefits: Enhanced Sound Insulation: The perforated and cavity structures effectively reduce external noise by blocking sound wave propagation paths at multiple levels. Polyurethane material has excellent sound absorption properties, absorbing some sound wave energy and significantly improving the sound insulation of the door and window, creating a quieter and more comfortable indoor environment. Optimized Heat Insulation: The perforated structure forms multiple air gaps within the cavity, hindering heat transfer through convection and thus strengthening the heat insulation effect. The filled polyurethane material not only fills the gaps inside the cavity but also provides an additional heat insulation barrier, ensuring superior heat insulation performance in high or low temperature environments.

[0027] In this embodiment, a thermally broken aluminum-wood door and window with good thermal insulation includes an aluminum material 3. A PA66 nylon thermal insulation strip 7 is snapped into the middle of the aluminum material 3. The thermal insulation cavity formed between the aluminum material 3 and the PA66 nylon thermal insulation strip 7 is filled with polyurethane filler 2. An equal pressure sealing strip 5 is provided at the rear end of the front aluminum material 3. The PA66 nylon thermal insulation strip 7 is connected next to the equal pressure sealing strip 5. A wide sealing strip 8 is provided at the upper end of the upper aluminum material 3. The other end of the wide sealing strip 8 is snapped into an opening sash 4. The other end of the opening sash 4 is snapped into the aluminum material 3. A soft and hard composite sealing strip 6 is snapped between the lower aluminum materials 3. An aluminum-lined buckle 11 is snapped into the upper right aluminum material 3. The aluminum-lined buckle 11 and the lower aluminum material 3 are connected by a hollow glass 1 in the middle. The hollow glass 1 can be connected by different buckles as needed.

[0028] The insulated glass 1 is a triple-glazed, double-cavity insulated glass. The equal pressure sealing strip 5 and the wide-face sealing strip 8 are soft and hard co-extruded composite strips. The opening fan 4 is made of eco-wood, and the opening fan 4 has a round hole designed inside its cavity.

[0029] In this embodiment, the aluminum material 3 is a 1.8mm thick thermally broken aluminum material, which has better wind pressure resistance.

[0030] In this embodiment, the aluminum-lined buckle 11 is connected by a mortise and tenon structure. After the mortise and tenon connection is installed, it can provide a force opposite to the displacement direction to prevent the structure from loosening.

[0031] In this embodiment, the PA66 nylon thermal insulation strip 7 is a 48mm multi-cavity nylon thermal insulation strip.

[0032] In this embodiment, the outer end of the upper right aluminum material 3 is connected to the fixing structure 9.

[0033] In this embodiment, the fixing structure 9 is provided with a slot 10 inside, and the right end of the upper right aluminum material 3 is connected to the fixing structure 9 through the slot 10.

[0034] This embodiment discloses a thermally broken aluminum-wood door and window with good thermal insulation properties. Its overall structural design is reasonable, its functionality is strong, and it combines aesthetics and practicality, which can meet the needs of modern buildings for high-performance doors and windows.

[0035] Door and window structure and function of each component: This door and window consists of thermally broken aluminum, PA66 nylon thermal break strips, polyurethane filler, insulated glass, composite sealing strips, operable sashes, and aluminum-lined locking moldings, etc. The specific structure and function are as follows:

[0036] Thermally broken aluminum profile: Utilizing 1.8mm thick thermally broken aluminum profile, this enhances the wind pressure resistance of doors and windows, making them particularly suitable for high-rise buildings and extreme weather conditions.

[0046] Frame assembly: The thermally broken aluminum frame is assembled using slots and fixing structures, and the aluminum-lined buckle is fixed with mortise and tenon structures to ensure the frame's sturdiness and airtightness.

[0047] Insulating glass installation: Select appropriate clips according to design requirements, and embed the triple-glazed double-cavity insulating glass into the door and window frame, ensuring that the sealing strip between the glass and the aluminum material is tightly fitted to prevent gas and moisture penetration.

[0048] Installation of the retractable fan: Attach the eco-wood retractable fan to the aluminum frame and secure its rotation position using hinges. During installation, pay attention to adjusting the position of the round holes to ensure a tight fit between the retractable fan's insulation cavity and the sealing strip.

[0049] Insulation cavity filling: Polyurethane material is filled into the insulation cavity between the thermally broken aluminum material and the insulation strip to ensure uniform and dense filling, so as to achieve the best thermal insulation and sound insulation effect.

[0050] Sealing treatment: Install soft and hard composite sealing strips at the joints of doors and windows, and adjust the position and tightness of the strips to ensure the sealing performance and elasticity of the strips.

[0051] Fixing and Adjustment: Fix the doors and windows in the reserved window openings, adjust the verticality and horizontality of the doors and windows through the fixing structure, and finally conduct an opening and closing test to ensure the flexibility and airtightness of the opening sash.

[0052] Superior sealing performance: The combination of soft and hard composite rubber strips and thermal expansion and contraction design ensures stable sealing performance during long-term use.

[0053] Significant thermal insulation and soundproofing effects: The multi-cavity design, polyurethane filling, and double-glazed glass work together to greatly improve the thermal insulation and soundproofing performance of doors and windows.

[0054] High structural stability: The mortise and tenon joint and slot fixing structure ensures the long-term stability of the doors and windows.

[0055] Easy to install and maintain: The combination of snap-fit ​​design and mortise and tenon structure makes the installation of doors and windows quick and efficient, reducing construction difficulty.
