Description

Technical Field

[0001] This utility model relates to the technical field of door and window profiles, and in particular to a double thermal break composite profile. Background Technology

[0002] Most windows currently on the market are constructed using aluminum profiles. Compared to aluminum-clad wood windows, aluminum profile windows are cheaper and more aesthetically pleasing. Compared to PVC profiles, they offer better insulation and security, making them a popular choice and widely used in construction projects. In home decoration, aluminum profile windows are commonly used to enclose balconies. Among these, thermally broken aluminum profiles consist of aluminum profiles on both sides connected by a nylon thermal break strip in the middle. Compared to traditional aluminum alloys, they undergo a special process to create a "thermal break" structure, forming a thermal bridge within the aluminum profile. This effectively blocks the heat conduction path of the aluminum alloy material, thus retaining the lightweight characteristics of aluminum alloy while improving its heat insulation and sound insulation effects.

[0003] In the existing technology, thermally broken aluminum profiles are widely used in the decoration design of the exterior walls of high-rise buildings due to their excellent heat insulation and sound insulation performance. However, there are still technical barriers, such as the low overall strength of thermally broken aluminum profiles, which are prone to deformation under the long-term action of the glass's own weight, resulting in a decrease in heat insulation and sealing performance, making it difficult to use them for processing large and extra-large doors and windows.

[0004] To improve sound insulation, heat preservation, and safety performance, windows often use triple or quadruple glazing for the frame or sash. These architectural glass panels, used in building exteriors, doors, and windows, come in various specifications, with lengths and widths customizable to specific needs. In large-sized doors and windows, the glass weight can reach several tons. The specific structure of thermally broken aluminum window frames is shown in CN202210799976.4, which describes a thermally broken aluminum internal suspension membrane window. According to this disclosure, the aluminum profiles on both the interior and exterior sides are connected by a nylon thermal break strip. The weight of the glass is directly loaded onto the nylon thermal break strip, and the wall opening cannot directly support it. Due to this connection method and the excessive weight of the glass, the aluminum profiles on both the interior and exterior sides will inevitably deform over long-term use, especially the bottom profile, which directly supports the glass and is prone to deformation, collapse, or even breakage under its own weight.

[0005] To address the issue of the limited strength of thermally broken aluminum profiles in manufacturing large-sized doors and windows, experts have conducted extensive research and made technological improvements. Thermally broken aluminum window frame profiles utilize two rings of nylon thermal break strips, one inside and one outside. Technicians have increased the thickness of these strips, replaced the materials used, and even added support structures to the outer ring to reinforce the wall openings, all to enhance the strength of the thermally broken aluminum window frame profiles. While these improvements have increased the support strength and slowed the deformation rate of the thermally broken aluminum profiles, the inner ring of the thermal break strip remains the primary support for the glass's weight. Regardless of the structural improvements, the inner ring remains essentially suspended (lacking support structures on its inner and outer sides except for its connection to the aluminum profile at both ends), failing to provide effective support. Therefore, the deformation of thermally broken aluminum profiles remains an unresolved problem.

[0006] Deformation of the bottom profile can also cause the glass to shift downwards, affecting the sealing of the top profile, resulting in a decrease in the overall strength of the window and a decline in its thermal insulation and sealing performance. At the same time, the deformed aluminum profile will squeeze the installation position of the window sash, causing the window sash to not close properly. If the deformation is too severe, it will affect the subsequent opening and closing of the window sash. Utility Model Content

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0058] Based on the above, this utility model also has the following embodiments:

[0059] In a further embodiment of this utility model, the inner aluminum profile 11, the first plastic profile 12, the frame connecting aluminum profile 13, the second plastic profile 14, and the outer aluminum profile 15 are connected by a roll-forming composite connection. Compared with the traditional single-segment nylon thermal break bridge, the length of the two plastic profiles of the double thermal break structure in the same specification and thickness of the door and window profile is shortened to about one-third. The strength after the roll-forming composite connection is higher, and the shear and bending moment resistance is better. The first plastic profile 12, the second plastic profile 14, the third plastic profile 22, and the fourth plastic profile 24 are preferably made of nylon. The frame connecting aluminum profile 13 and the sash connecting aluminum profile 23 are aluminum alloy profiles. Compared with nylon, the frame connecting aluminum profile 13 and the sash connecting aluminum profile 23 have higher strength and can directly support the glass, which improves the strength and load-bearing capacity of the frame profile 1 and the sash profile 2. They can withstand the weight of large-size glass without deformation, solving the problem that thermal break aluminum profiles are difficult to use for processing large and extra-large doors and windows.

[0060] like Figure 1 and Figure 5As shown, a double thermal break structure is formed by adding a first plastic profile 12 and a second plastic profile 14 to the aluminum profile 11 inside the frame and the aluminum profile 15 outside the frame.

[0061] like Figure 1 and Figure 6 As shown, a double thermal break structure is formed by adding a third plastic profile 22 and a fourth plastic profile 24 to the aluminum profile 21 inside the fan and the aluminum profile 25 outside the fan.

[0062] The combination doors and windows based on the double thermal break structure design can effectively improve heat insulation and sound insulation performance, effectively reduce heat loss, and have significant advantages in heat preservation, heat insulation, sound insulation and energy saving.

[0063] The frame profile 1 is installed inside the wall opening. The outer perimeter of the aluminum profile 11 inside the frame, both the exterior and interior sides, are provided with first support claws 111. The outer perimeter of the aluminum profile 15 outside the frame, both the exterior and interior sides, are provided with second support claws 121. Figures 1 to 3 As shown, the first support claw 111 and the second support claw 121 are used to support the combined doors and windows based on the double thermal break structure design, increase the overall support strength of the combined doors and windows, and improve the wind pressure resistance performance under extreme weather conditions.

[0064] The installation positions of the frame connecting aluminum profile 13 and the sash connecting aluminum profile 23 are as follows: Figures 1 to 6 As shown, the first, second, third, and fourth strip-shaped snap-fit ​​parts have the same dimensions, and the first, second, third, fourth, fifth, and sixth plastic profile snap-fit ​​grooves have the same dimensions. Based on this structure, the first plastic profile 12, the frame connecting aluminum profile 13, and the second plastic profile 14 can be adapted to various aluminum profiles 11 and 15 of the same or similar size inside the frame and outside the frame. The third plastic profile 22, the fan connecting aluminum profile 23, and the fourth plastic profile 24 can also be adapted to various aluminum profiles 21 and 25 of the same or similar size inside the fan and outside the fan. No additional processing is required, and they can be directly installed on the already processed frame profile 1 and fan profile 2.

[0065] In a further embodiment of this utility model, the positions of the first support claw 111, the third support claw 131, and the second support claw 121 are as follows: Figure 2As shown, the first plastic profile 12 is supported on both sides by a first support claw 111 and a third support claw 131, respectively. The second plastic profile 14 is supported on both sides by a second support claw 121 and a third support claw 131, respectively. By shortening the plastic profile and adding the frame connecting aluminum profile 13, the shear and bending moment resistance of the frame profile 1 is improved. The frame connecting aluminum profile 13 provides auxiliary support, which improves the support performance of the frame profile 1 for the weight of the glass. Using five rows of support claws, including two first support claws 111, one third support claw 131, and two second support claws 121, the weight of the glass is directly transferred to the wall opening, improving the strength and support performance of the frame profile 1. This makes it possible to use thermally broken aluminum profiles to process large and extra-large doors and windows. Based on the existing single-segment thermal break bridge with low strength, it will deform, collapse, or even break under the weight of the glass. The double thermal break structure breaks through the technical barrier, and the effect produced by its improvement is undoubtedly huge.

[0066] like Figure 1 and Figure 3 As shown, the main sealing strip 17 simultaneously abuts against the fan-connecting aluminum profile 23 and the fourth plastic profile 24, achieving a sealing effect through multiple layers of barrier.

[0067] In a further embodiment of this utility model, the frame glass clamping profile 16 is used to clamp the frame glass, the sash glass clamping profile 26 is used to clamp the sash glass, and glass sealant strips for sealing are respectively installed on the indoor and outdoor sides of the glass.

[0068] In a further embodiment of this utility model, such as Figures 1 to 4 The diagram shows a horizontal cross-sectional view of the double-thermal-break composite profile, which includes: a cross-sectional view of the fixed sash side outer frame profile 101, a cross-sectional view of the middle frame profile 102, and a cross-sectional view of the opening sash side outer frame profile 103. Glass can be directly installed between the fixed sash side outer frame profile 101 and the middle frame profile 102 to form a fixed sash that cannot be opened or closed. The middle frame profile 102 and the opening sash side outer frame profile 103 form a window frame for installing the window sash. After glass is installed inside the sash profile 2, a window sash is formed. The window sash and the window frame on the opening sash side are connected by hardware to achieve opening and closing methods such as casement and top-hung.

[0069] The cross-sections of the upper and lower fixed frames on the fixed fan side are the same as those of the outer frame profile 101 on the fixed fan side, so no cross-sectional views of the upper and lower fixed frames on the fixed fan side have been added. The cross-sections of the upper and lower fixed frames on the open fan side are the same as those of the outer frame profile 103 on the open fan side, so no cross-sectional views of the upper and lower fixed frames on the open fan side have been added.

[0070] Since the upper and lower frames of the window sash are in the same direction as the left and right, cross-sectional views of the upper and lower frames of the window sash were not added.

[0071] In a further embodiment of this utility model, such as Figures 1 to 6 As shown, the frame inner sealing strip 27, main sealing strip 17 and frame outer sealing strip 18 designed from the indoor side to the outdoor side achieve multiple seals at the opening and closing positions of the window sash and window frame. The multiple sealing strips work together to achieve functions such as heat insulation, sound insulation and noise reduction.

[0072] In a further embodiment of this utility model, a double-broken bridge frame profile 1 is formed by combining a first plastic profile 12, a frame-connecting aluminum profile 13, and a second plastic profile 14, and a double-broken bridge fan profile 2 is formed by combining a third plastic profile 22, a fan-connecting aluminum profile 23, and a fourth plastic profile 24. Two thermal break bridges are formed inside the aluminum profile, thereby effectively blocking the heat conduction path of the aluminum alloy material. This not only retains the lightweight characteristics of aluminum alloy, but also improves its heat insulation and sound insulation effects. Compared with a single-segment thermal break bridge, it effectively improves heat insulation and sound insulation performance, effectively slows down heat loss, and has significant advantages in terms of heat preservation, heat insulation, sound insulation, and energy saving.

[0073] In a further embodiment of this utility model, the inner and outer sides of the frame connecting aluminum profile 13 are provided with third support claws 131. When the frame profile 1 is installed in the wall opening, the third support claws 131 located on the outer periphery of the window frame can cooperate with the first support claws 111 and the second support claws 121 to support the combined door and window based on the double thermal break structure design. The frame connecting aluminum profile 13 is located at the glass installation position, and the third support claws 131 located on the inner periphery abut against the outer edge of the glass, which can directly support the glass and transfer the stress exerted by the glass on the frame profile 1 to the wall, reducing the impact of the mass of the large-size glass on the frame profile 1 and improving the overall strength of the frame profile 1. Based on the double thermal break structure design, it can be used to design large-size aluminum profile doors and windows.

[0074] In a further embodiment of this utility model, the inner and outer sides of the frame connecting aluminum profile 13 are provided with third support claws 131. The third support claws 131 located on the inner periphery abut against the outer edge of the glass, and the third support claws 131 located on the inner periphery abut against the wall opening, which can directly support the glass and transfer the stress applied by the glass to the frame profile 1 to the wall. At the same time, the outdoor side and the indoor side are provided with separate thermal break structures. Based on the double thermal break structure design, the heat conduction path of the aluminum alloy material is effectively blocked.

[0075] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
