Description

A novel aluminum composite energy-saving door and window profile structure and door and window Technical Field

[0001] This utility model relates to the field of doors and windows, specifically to a new type of aluminum composite energy-saving door and window profile structure and door and window. Background Technology

[0002] Doors and windows are an important part of a building's external envelope, serving functions such as sheltering from wind and rain, heat insulation, sound insulation, lighting, and ventilation. With the improvement of people's living standards and the promotion of environmental protection and energy conservation concepts, the requirements for doors and windows in decoration are becoming increasingly higher, leading to the widespread application of PVC windows and thermally broken aluminum windows in buildings.

[0003] Existing PVC windows have good thermal insulation properties, but they have low hardness, poor wind resistance, and are prone to fading, deformation, aging, and cracking.

[0004] Existing thermally broken aluminum windows and doors are highly rigid and not easily deformed, but they are typically constructed from inner and outer aluminum alloy profiles connected by a thermal break strip in between. The thermal break strip separates the two aluminum alloy profiles, thus blocking heat conduction and providing thermal insulation. However, thermally broken aluminum windows and doors are designed primarily with aluminum alloy profiles and the thermal break strip as a secondary component. Because aluminum alloy conducts heat quickly, and the width of the aluminum alloy profiles accounts for more than half, even two-thirds, the thermal break strip is not effective at insulating heat, resulting in poor thermal insulation performance and inadequate heat preservation. Summary of the Invention

Detailed Implementation

[0033] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0034] Please refer to Figures 1-3, which show the overall structural diagram of the new aluminum composite energy-saving door and window profile.

[0035] This embodiment provides a novel aluminum composite energy-saving door and window, including at least two aluminum alloy profiles 1 and thermal insulation strips 2 connected between multiple aluminum alloy profiles 1. The ratio of the total width of the two aluminum alloy profiles 1 to the total width of the thermal insulation strip 2 is 1:1-5.

[0036] The following will further describe a novel aluminum composite energy-saving door and window profile structure according to this exemplary embodiment.

[0037] In some embodiments, the above-mentioned profile structure is composed of aluminum alloy profile 1 and thermal insulation strip 2, including at least two aluminum alloy profiles 1 and thermal insulation strip 2 connected between the two aluminum alloy profiles 1. The ratio of the total width of the two aluminum alloy profiles 1 to the total width of the thermal insulation strip 2 is 1:1-5, that is, the width ratio of the aluminum alloy profile 1 is less than or equal to the width ratio of the thermal insulation strip 2, preferably less than, so that the profile structure is mainly made of thermal insulation strip 2 and supplemented by aluminum alloy material. Through the design of the size ratio, the thermal insulation performance can be improved while ensuring strength.

[0038] It should be noted that the profile structure includes at least two aluminum alloy profiles 1 and a thermal insulation strip 2 connecting the two aluminum alloy profiles 1. That is, there can be multiple aluminum alloy profiles 1 and thermal insulation strips 2 connecting multiple aluminum alloy profiles 1. Specifically, it can be a structure of aluminum alloy profile 1 + thermal insulation strip 2 + aluminum alloy profile 1, as shown in Figure 1; or it can be a structure of aluminum alloy profile 1 + thermal insulation strip 2 + aluminum alloy profile 1 + thermal insulation strip 2 + aluminum alloy profile 1, as shown in Figure 2. It can be manufactured according to the specific requirements of the actual application site, application area, width, strength and other requirements.

[0039] In one specific embodiment, the profile structure can have various widths such as 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 100mm, 120mm, and 150mm. Taking an 80mm profile structure as an example, it includes aluminum alloy profiles 1 on both sides and a thermal break strip 2 in the middle. The thermal break strip 2 is 60mm wide, and the total width of the two aluminum alloy profiles 1 is 20mm, with the ratio of the total width of the aluminum alloy profiles 1 to the width of the thermal break strip 2 being approximately 1:3; or the thermal break strip 2 is 50mm wide, and the total width of the two aluminum alloy profiles 1 is 30mm, with the ratio of the total width of the aluminum alloy profiles 1 to the width of the thermal break strip 2 being approximately 1:1.6; or the thermal break strip 2 is 40mm wide, and the total width of the two aluminum alloy profiles 1 is 40mm, with the ratio of the total width of the aluminum alloy profiles 1 to the width of the thermal break strip 2 being approximately 1:1.

[0040] As a preferred implementation method, in order to further improve the thermal insulation performance, a plurality of first thermal insulation cavities 21 are provided along the width direction of the above-mentioned thermal insulation strip 2, which can both insulate sound and heat, increase air tightness, and improve sound and heat insulation performance.

[0041] In a preferred embodiment, the heat insulation strip 2 is integrally formed; or, the heat insulation strip 2 is formed by mortise and tenon joints or overlapping of two heat insulation units 23, preferably by mortise and tenon joints, with the two heat insulation units 23 joined together to form multiple first heat insulation cavities 21. That is, the heat insulation strip 2 can be integrally formed, with multiple first cavities formed simultaneously, or it can be formed by mortise and tenon joints of two heat insulation units 23, with joint strips extending vertically from the jointing sides of the two heat insulation units 23, and the joint strips being mortise and tenon jointed to form multiple first heat insulation cavities 21.

[0042] In this embodiment, it is preferable that the heat insulation strip 2 is formed by two heat insulation units 23 connected by tenon and mortise joints, and the separate design can reduce production costs.

[0043] In a preferred embodiment, a second heat insulation cavity 22 is formed between the heat insulation strip 2 and the aluminum alloy profile 1. Specifically, the end of the heat insulation strip 2 is provided with a connecting rib for connecting with the aluminum alloy profile 1. The connection method adopts a common connection method in the prior art. The connecting rib extends outward for a certain length, so that when it is connected with the aluminum alloy profile 1, a second heat insulation cavity 22 is formed between the heat insulation strip and the aluminum alloy profile 1, further improving the heat insulation performance.

[0044] As a preferred embodiment, the above-mentioned heat insulation strip 2 is made of PA66, PVC or UPVC. In this embodiment, PA66 (nylon 66) is preferred, that is, aluminum alloy profile 1 is combined with nylon 66. Combining the inherent characteristics of aluminum alloy such as light weight, high strength and high durability and nylon 66 such as high strength and high heat insulation, the profile structure has high strength and heat insulation performance.

[0045] Referring to Figures 4-6, this application embodiment also includes a novel aluminum composite energy-saving door and window, comprising a frame assembly 3, a sash assembly 4, and a mullion assembly. The frame assembly 3, sash assembly 4, and mullion assembly are respectively constructed using the profile structures described above. The sash assembly 4 is rotatably connected to the frame assembly 3 to form a sliding door and window, as shown in Figures 4 and 5. The mullion assembly is connected to the frame assembly to improve the strength of the door and window. This door and window, using the aforementioned profile structure, has high thermal insulation performance and high strength. Its appearance is decorated with aluminum alloy profiles 1, making it aesthetically pleasing and available in various colors, and can be customized.

[0046] It should be noted that the aforementioned frame components can be door frames or window frames, and the aforementioned sash components can be door sashes or window sashes. Figure 4 shows a structural schematic diagram of the door frame component and the door sash component, and Figure 5 shows a structural schematic diagram of the window frame component and the window sash component. Figure 6 shows a structural schematic diagram of the mullion component.

[0047] In some embodiments, adjacent frame edges of the frame assembly 3 and sash assembly 4 are connected by at least two corner brackets (not shown), preferably three corner brackets. These three corner brackets may include two aluminum alloy corner brackets and one PVC or PA66 corner bracket. The two aluminum alloy corner brackets connect to the inner and outer aluminum alloy profiles 1, respectively, while the PVC or PA66 corner bracket connects to the thermal break strip 2. Alternatively, the three corner brackets may consist of three aluminum alloy corner brackets, each connecting to both the inner and outer aluminum alloy profiles 1 and the thermal break strip 2. Specifically, an adhesive injection process can be used for connection. By employing a three-set corner bracket design to form a composite door and window, the strength of the door and window can be further improved.

[0048] In a preferred embodiment, the frame assembly 3 includes at least two first aluminum alloy profiles 31 and a first thermal break strip 32 connecting the plurality of first aluminum alloy profiles 31; the sash assembly 4 includes at least two second aluminum alloy profiles 41 and a second thermal break strip 42 connecting the plurality of second aluminum alloy profiles 41. Depending on requirements, a plurality of first aluminum alloy profiles 31 and a plurality of first thermal break strips 32 can be provided, or a plurality of second aluminum alloy profiles 41 and a plurality of second thermal break strips 42 can be provided accordingly. The first aluminum alloy profiles 31 and second aluminum alloy profiles 41 located on both sides serve as fixing and decorative elements on the inner and outer sides of the door and window, while the first aluminum alloy profiles 31 and second aluminum alloy profiles 41 located on the inner side can improve the overall strength of the door and window. When multiple profiles are provided, the number of corner brackets can be increased accordingly, and the corner bracket material can be selected accordingly. Aluminum alloy profile 1 uses aluminum alloy corner brackets, and thermal break strip 2 uses corner brackets of a corresponding material to enhance assembly strength.

[0049] In a preferred embodiment, one end of the inner side of one of the second aluminum alloy profiles 41 is provided with an inwardly hooked first pressure line hook 411, and the other end is provided with an inwardly hooked first locking bar hook 412. One side of the second thermal insulation strip 42 is provided with a second pressure line hook 421 opposite to the first pressure line hook 411, forming a pressure line groove 43. The pressure line groove 43 is used to fix the pressure line 45 for easy glass installation. The other side of the second thermal insulation strip 42 is provided with a second locking bar hook 422 opposite to the first locking bar hook 412, forming a locking bar groove 44. The locking bar groove 44 is used to insert a lock, enabling the sash assembly 4 to be rotatably connected to the frame assembly 3, thus allowing the door and window to open and close.

[0050] In traditional aluminum alloy thermal break designs, both the locking groove 44 and the pressure groove 43 are located on the aluminum alloy profile 1, which significantly limits the width of the aluminum alloy profile 1 within the overall profile structure, making it account for a large proportion and thus affecting the thermal insulation performance of the thermal break strip 2. This application addresses this by placing one of the locking hooks of the locking groove 44 and one of the pressure hooks of the pressure groove 43 on the thermal break strip 2, while maintaining sufficient strength in the aluminum alloy tube cavity. This increases the width of the thermal break strip 2 and improves its thermal insulation performance.

[0051] In a preferred embodiment, multiple reinforcing ribs 321 extend vertically from both sides of the first heat insulation strip 32 to form a rubber strip assembly groove, which is used to limit the rubber strip between the mounting frame assembly 3 and the fan assembly 4 and ensure the stability of the rubber strip.

[0052] The beneficial effects of the embodiments of this application are as follows:

[0053] The aluminum alloy profile 1 adopts an ultra-narrow design, which ensures strength while leaving enough space for the thermal insulation strip 2, greatly improving the thermal insulation performance. In addition, the material is clean and environmentally friendly, energy-saving and reducing carbon emissions.

[0054] The heat insulation strip 2 and the aluminum alloy profile 1 are combined to form the pressure groove 43 and the locking strip groove 44, so as to form the extremely narrow aluminum alloy profile 1.

[0055] The multi-corner bracket design of composite doors and windows improves assembly strength.

[0056] The heat insulation strip is made of mortise and tenon joints to form a multi-cavity design, which increases air tightness, sound insulation and heat insulation, and the independent manufacturing process can reduce production costs.
