Description

Technical Field

[0001] The present invention relates to the technical field of door and window profiles, and in particular to a novel double-broken bridge composite profile and a double-broken bridge door and window. Background Art

[0002] Most windows today are constructed from aluminum profiles. Compared to aluminum-clad wood windows, aluminum profile windows are inexpensive and more refined and aesthetically pleasing. Compared to plastic-steel profiles, they offer superior thermal insulation and anti-theft properties, making them popular and widely used in construction. In home decoration, aluminum profile doors and windows are often used to enclose balconies. Thermally-insulated aluminum profiles, which are made up of aluminum profiles on both sides connected by nylon insulation strips in the middle, differ from traditional aluminum alloys in that they utilize a special process to create a "broken bridge" structure. This creates an insulating bridge within the aluminum profile, effectively blocking the heat conduction path of the aluminum alloy. This preserves the lightweight characteristics of aluminum alloy while improving its thermal and sound insulation properties.

[0003] In the existing technology, thermal break aluminum profiles are widely popular in the decorative design of high-rise building exterior walls due to their excellent thermal insulation and sound insulation properties. However, there are still technical barriers. For example, the overall strength of the thermal break aluminum profile is low, and it is easy to deform under the long-term action of the glass's own weight, resulting in a decrease in thermal insulation and sealing performance, making it difficult to use it for processing large and extra-large doors and windows.

[0004] In order to improve the sound insulation, heat preservation and safety performance of windows, frame glass or sash glass mostly adopts three or four layers of glass. Architectural glass used for building exterior walls, doors and windows, etc. has various specifications, and the length and width can be customized according to specific needs. Specifically, the glass weight of large-sized doors and windows can reach several tons. The specific structure of the thermal break aluminum window frame profile is shown in the thermal break aluminum inner suspended film door and window proposed in CN202210799976.4, and see the figure in the specification. Figure 8 According to the disclosure, the indoor and outdoor aluminum profiles are connected by nylon insulation strips. The weight of the glass directly loads the nylon insulation strips, and the wall opening cannot directly support the nylon insulation strips. Due to the heavy weight of the glass, this connection method will inevitably cause deformation of the indoor and outdoor aluminum profiles during long-term use. In particular, the bottom profile, which directly supports the glass, will deform, collapse, or even break under the weight of the glass.

[0005] In order to solve the problem that the strength of thermally broken aluminum profiles is difficult to use for processing large-sized doors and windows, technicians in this field have also made a lot of research and improved the technology, such as Figure 8As shown, the thermally-broken aluminum window frame profile adopts two circles of nylon insulation strips inside and outside. The technicians have increased the thickness of the nylon insulation strips, replaced the material of the nylon insulation strips, and even added a supporting structure to the outer circle of the nylon insulation strips to offset the wall opening to improve the strength of the thermally-broken aluminum window frame profile. Although some improvements have increased the supporting strength of the thermally-broken aluminum profile and slowed down the deformation rate of the thermally-broken aluminum profile, the inner circle of the nylon insulation strips is always the most important part that bears the deadweight of the glass. No matter which structural improvement is made, the inner circle of the nylon insulation strips is still in an overhead state (except for the two ends connected to the aluminum profile, there is no supporting structure on the inside and outside), and it cannot provide effective support for it. Therefore, the deformation of the thermally-broken aluminum profile is still an unsolved problem.

[0006] The deformation of the bottom profile will also cause the glass to move downward as a whole, affecting the sealing of the top profile, resulting in a decrease in the overall strength of the window, and a decrease in thermal insulation and sealing performance. At the same time, the aluminum profile will squeeze the installation position of the window sash after deformation, causing the window sash to not close tightly. If the deformation is too severe, it will affect the subsequent opening and closing of the window sash. Summary of the Invention

[0007] In view of the problem that the above-mentioned thermally-broken aluminum profiles are difficult to use for processing large-sized and extra-large-sized doors and windows, and are subjected to the stress exerted by the glass for a long time during use, the aluminum profiles on both indoor and outdoor sides will be deformed, affecting the thermal insulation and sealing performance of the doors and windows, the purpose of the present invention is to provide a new type of double-broken bridge composite profile and double-broken bridge door and window. The first thermally-broken bridge connecting profile is respectively against the outer edge of the glass and the wall opening, which can directly support the glass and transfer the stress exerted by the glass on the window frame profile to the wall, thereby reducing the impact of the quality of large-sized glass on the window frame profile.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] A novel double-broken bridge composite profile, comprising: a window frame profile 1 and a window sash profile 2, wherein the window sash profile 2 is assembled on the opening side of the window frame profile 1, and the window frame profile 1 is installed in a wall opening;

[0010] The window frame profile 1 includes: an inner aluminum profile 11, a first plastic profile 12, a first thermal break connecting profile 13, a second plastic profile 14, and an outer aluminum profile 15. The first thermal break connecting profile 13 is arranged between the inner aluminum profile 11 and the outer aluminum profile 15. The profiles on any side of the inner aluminum profile 11 and the profiles at corresponding positions on the first thermal break connecting profile 13 are compositely connected by the inner and outer first plastic profiles 12. The profiles on any side of the outer aluminum profile 15 and the profiles at corresponding positions on the first thermal break connecting profile 13 are compositely connected by the inner and outer second plastic profiles 14. The outer peripheral edge of the outdoor side and the inner peripheral edge of the inner aluminum profile 11 are both provided with a first support portion 111, and the outer peripheral edge of the outdoor side and the inner peripheral edge of the outer aluminum profile 15 are both provided with a second support portion 151.

[0011] The window sash profile 2 includes: an inner aluminum profile 21 of the window sash, a third plastic profile 22, a second thermal break connecting profile 23, a fourth plastic profile 24 and an outer aluminum profile 25 of the window sash. The second thermal break connecting profile 23 is arranged between the inner aluminum profile 21 of the window sash and the outer aluminum profile 25 of the window sash. The profiles on any side of the inner aluminum profile 21 of the window sash and the profiles at the corresponding positions on the second thermal break connecting profile 23 are compositely connected by the inner and outer third plastic profiles 22. The profiles on any side of the outer aluminum profile 25 of the window sash and the profiles at the corresponding positions on the second thermal break connecting profile 23 are compositely connected by the inner and outer fourth plastic profiles 24.

[0012] The aluminum profile 11 inside the window frame, the first plastic profile 12, the first thermal break connecting profile 13, the second plastic profile 14 and the aluminum profile 15 outside the window frame are connected by rolling composite. Compared with the traditional single-section nylon insulation bridge, the length of the two sections of plastic profiles of the double thermal break structure in the door and window profiles of the same specification and thickness is shortened to about one third. The strength after rolling composite connection is higher, and the shear and bending moment resistance is better. The material of the first plastic profile 12, the second plastic profile 14, the third plastic profile 22 and the fourth plastic profile 24 is preferably nylon, and the first thermal break connecting profile 13 and the second thermal break connecting profile 23 are aluminum alloy profiles. Compared with nylon material, the first thermal break connecting profile 13 and the second thermal break connecting profile 23 have higher strength and can directly support the glass, thereby improving the strength and load-bearing capacity of the window frame profile 1 and the window sash profile 2, and can withstand the dead weight of large-size glass without deformation, solving the problem that thermal break aluminum profiles are difficult to use for processing large-size and extra-large-size doors and windows.

[0013] The above-mentioned new double-broken bridge composite profile, in which the aluminum profile 11 inside the window frame, the first plastic profile 12, the first broken bridge connecting profile 13, the second plastic profile 14 and the aluminum profile 15 outside the window frame are connected by rolling composite connection, requires a broken bridge thermal insulation aluminum profile rolling composite machine that can simultaneously realize three-plus-two mode composite connection of the aluminum profile 11 inside the window frame, the first plastic profile 12, the first broken bridge connecting profile 13, the second plastic profile 14 and the aluminum profile 15 outside the window frame. Based on this structure, the inventor has made technical improvements to the existing broken bridge thermal insulation aluminum profile rolling composite machine to adapt to the double-broken bridge composite profile of the present invention. However, there is no broken bridge thermal insulation aluminum profile rolling composite machine adapted to the present invention in the existing technology or on the market. Based on the technical search of the double-broken bridge structure and the broken bridge thermal insulation aluminum profile rolling composite machine of the present invention, the applicant believes that the existing technology does not provide relevant ideas or technical inspiration.

The main sealing strip 17 is installed on the third strip-shaped clamping portion 132 on the inner side of the first broken bridge connecting profile 13 on the open sash side, and the outdoor sealing strip 18 is installed on the inner edge of the window frame outer aluminum profile 15 on the open sash side. When the window sash profile 2 is in a closed state, the main sealing strip 17 and the outdoor sealing strip 18 are both used to seal between the window frame profile 1 and the window sash profile 2.

[0020] The above-mentioned new double-broken bridge composite profile, wherein the inner periphery of the window sash profile 2 is used to install the sash glass; the window sash profile 2 also includes: a second pressing profile 27, which is installed on the inner edge of the aluminum profile 21 inside the window sash, and the second pressing profile 27 is used to press the sash glass.

When the window sash profile 2 is in a closed state, the outer frame sealing strip 31 is against the outdoor side of the outer aluminum profile 25 of the window sash. The outer frame sealing strip 31 is used to seal between the window frame profile 1 and the window sash profile 2.

[0025] A double-break bridge door and window comprises the novel double-break bridge composite profile mentioned above, wherein both the window frame profile 1 and the window sash profile 2 are installed with sash glass.

[0026] Due to the adoption of the above technology, the present invention has the following positive effects compared with the prior art:

[0027] (1) The present invention adopts a double-broken bridge window frame profile composed of a first plastic profile, a first broken bridge connecting profile and a second plastic profile, and a double-broken bridge window sash profile composed of a third plastic profile, a second broken bridge connecting profile and a fourth plastic profile, to form two sections of thermal insulation bridges inside the aluminum profile, thereby effectively blocking the heat conduction path of the aluminum alloy material. In this way, the lightweight and high-strength characteristics of the aluminum alloy are retained, and its thermal insulation and sound insulation effects are improved. Compared with a single-section thermal insulation bridge, the thermal insulation and sound insulation performance are effectively improved, and the loss of heat is effectively slowed down, which has significant advantages in terms of heat preservation, heat insulation, sound insulation, energy saving, etc.

[0028] (2) In the present invention, the inner and outer sides of the first thermal break connecting profile are both provided with a third strip-shaped clamping portion.

The first thermal break connecting profile is located at the installation position of the glass and can directly support the glass, transfer the stress exerted by the glass on the window frame profile to the wall, reduce the influence of the mass of the large-size glass on the window frame profile, and improve the overall strength of the window frame profile. The double thermal break structure design can be used to design large-size aluminum profile doors and windows.

[0029] (3) In the present invention, the aluminum profile outside the window frame, the first plastic profile, the first thermal break connecting profile, the second plastic profile and the aluminum profile inside the window frame are connected by rolling composite. Compared with the traditional single-section nylon insulation bridge, the two sections of the plastic profile of the double thermal break structure are shorter, and the strength after the rolling composite connection is higher, and the shear and bending moment resistance is better. The material of the first plastic profile, the second plastic profile, the third plastic profile and the fourth plastic profile is preferably nylon, and the first thermal break connecting profile and the second thermal break connecting profile are aluminum alloy profiles. Compared with nylon material, the first thermal break connecting profile and the second thermal break connecting profile have higher strength and can directly support the glass, thereby improving the strength and load-bearing capacity of the window frame profile and the window sash profile, and can withstand the weight of large-sized glass without deformation, solving the problem that the thermal break aluminum profile is difficult to use for processing large-sized and extra-large-sized doors and windows.

The first thermal break connecting profile 13 is arranged between the inner aluminum profile 11 and the outer aluminum profile 15.

[0054] Two rows of sixth plastic profile snap-in grooves are provided on the indoor side of the profile on either side of the window sash outer aluminum profile 25, and both rows of sixth plastic profile snap-in grooves match the fifth strip snap-in portion;

[0055] The installation positions of the first thermal break connecting profile 13 and the second thermal break connecting profile 23 are as follows: Figures 1 to 6 As shown, the first plastic profile clamping groove 131 on the first broken bridge connecting profile 13 and the third strip clamping portion 132 are as shown in FIG. Figure 7As shown, the first strip clamping portion, the second strip clamping portion, the fourth strip clamping portion and the fifth strip clamping portion have the same specifications and sizes, and the first plastic profile clamping groove 131, the second plastic profile clamping groove, the third plastic profile clamping groove, the fourth plastic profile clamping groove, the fifth plastic profile clamping groove and the sixth plastic profile clamping groove have the same specifications and sizes. Based on this structure, the first plastic profile 12, the first thermally broken bridge connecting profile 13 and the second plastic profile 14 can adapt to a variety of identical or similar sizes of aluminum profiles 11 inside the window frame and aluminum profiles 15 outside the window frame. The third plastic profile 22, the second thermally broken bridge connecting profile 23 and the fourth plastic profile 24 can also adapt to a variety of identical or similar sizes of aluminum profiles 21 inside the window sash and aluminum profiles 25 outside the window sash. No additional processing is required, and they can be directly installed on the processed window frame profile 1 and window sash profile 2.

[0056] Furthermore, in a preferred embodiment, the fixed sash side of the window frame profile 1 is used to install the sash glass; the window frame profile 1 also includes: a first clamping profile 16, the first clamping profile 16 is installed on the inner edge of the aluminum profile 11 in the window frame on the fixed sash side, and the first clamping profile 16 is used to clamp the sash glass on the fixed sash side.

[0057] Furthermore, in a preferred embodiment, the opening sash side of the window frame profile 1 is used to install the window sash profile 2, and the window frame profile 1 also includes: a main sealing strip 17 and an outdoor sealing strip 18. The main sealing strip 17 is installed on the third strip-shaped clamping portion 132 on the inner side of the first broken bridge connecting profile 13 on the opening sash side, and the outdoor sealing strip 18 is installed on the inner edge of the window frame outer aluminum profile 15 on the opening sash side. When the window sash profile 2 is in a closed state, the main sealing strip 17 and the outdoor sealing strip 18 are both used to seal between the window frame profile 1 and the window sash profile 2.

[0058] Furthermore, in a preferred embodiment, the positions of the first supporting portion 111, the third strip-shaped clamping portion 132 and the second supporting portion 151 are as follows: Figure 2As shown, the two sides of the first plastic profile 12 are supported by a first supporting portion 111 and a third strip clamping portion 132 respectively, and the two sides of the second plastic profile 14 are supported by a second supporting portion 151 and a third strip clamping portion 132 respectively. By shortening the plastic profile and adding the first broken bridge connecting profile 13 to improve the shear and bending moment resistance of the window frame profile 1, and by auxiliary support through the first broken bridge connecting profile 13, the supporting performance of the window frame profile 1 for the dead weight of the glass is improved. A total of five rows of supporting claws, including two first supporting portions 111, a third strip clamping portion 132 and two second supporting portions 151, are used to directly transfer the dead weight of the glass into the wall opening, thereby improving the strength and supporting performance of the window frame profile 1, and realizing the possibility of using the broken bridge aluminum profile for processing large and extra-large doors and windows. Based on the low strength of the existing single-section thermal insulation bridge, deformation, collapse, and even fracture may occur under the action of the dead weight of the glass. The double broken bridge structure breaks the technical barriers, and the effect produced by the improvement is undoubtedly huge.

[0059] like Figure 1 and Figure 3 As shown, the main sealing strip 17 is against the second thermal break connecting profile 23 and the fourth plastic profile 24 at the same time, achieving a sealing effect through multi-layer barrier.

[0060] Furthermore, in a preferred embodiment, the inner periphery of the window sash profile 2 is used to install the sash glass; the window sash profile 2 also includes: a second pressing profile 27, the second pressing profile 27 is installed on the inner edge of the aluminum profile 21 inside the window sash, the second pressing profile 27 is used to press the sash glass, and the indoor and outdoor sides of the sash glass are respectively equipped with glass strips for sealing.

[0061] Furthermore, in a preferred embodiment, the window sash profile 2 also includes: an indoor sealing strip 26, which is installed on the outer edge of the aluminum profile 21 inside the window sash. When the window sash profile 2 is in a closed state, the indoor sealing strip 26 is used to seal between the window frame profile 1 and the window sash profile 2.

[0062] Furthermore, in a preferred embodiment, the window frame profile 1 also includes: a first outside-frame pressed aluminum 28 and a second outside-frame pressed aluminum 29, the first outside-frame pressed aluminum 28 and the second outside-frame pressed aluminum 29 are both located on the outdoor side of the opening sash side of the window frame profile 1, the second outside-frame pressed aluminum 29 is installed on the outdoor side of the window frame outside aluminum profile 15, and the first outside-frame pressed aluminum 28 is installed on the outdoor side of the window frame outside aluminum profile 15 and is used to press the second outside-frame pressed aluminum 29.

[0063] The first frame outer pressed aluminum 28 and the second frame outer pressed aluminum 29 are suitable for large-sized thermally insulated aluminum doors and windows. In order to improve the indoor light transmittance and improve the aesthetics, designers often use a structure in which large-sized glass is installed on the fixed fan side of the window frame profile 1. The installation position is as follows: Figure 1 and Figure 2As shown, the adoption of this structural design can effectively improve the indoor light transmittance, but due to the large mass of the glass, ordinary thermal break aluminum profiles are difficult to support the mass of large-sized glass, which will accelerate the deformation of the window frame profile 1 and affect the sealing performance of doors and windows. If the window frame profile 1 is severely deformed, its extrusion on the window sash profile 2 will also increase, and finally it will make the window sash profile 2 difficult to open and close. In order to improve the supporting performance and overall strength of the thermal break aluminum profile for large-sized glass, the present invention adopts a double thermal break structure composed of a first plastic profile 12, a first thermal break connecting profile 13 and a second plastic profile 14, and auxiliary support is provided to the large-sized glass through the first thermal break connecting profile 13, see Figure 1 、 Figure 2 and Figure 7 The inner and outer sides of the first thermal break connecting profile 13 are both provided with a third strip clamping portion 132. When the window frame profile 1 is installed in the wall opening, the third strip clamping portion 132 can cooperate with the first support portion 111 and the second support portion 151 to support the combined doors and windows based on the double thermal break structure design, and the first thermal break connecting profile 13 is located at the installation position of the large-size glass, which can directly support the glass and transfer the stress applied by the glass to the window frame profile 1 to the wall, thereby reducing the influence of the quality of the large-size glass on the window frame profile 1 and improving the overall strength of the window frame profile 1. The design based on the double thermal break structure can be used to design large-size aluminum profile doors and windows.

[0064] Furthermore, in a preferred embodiment, the window frame profile 1 further includes: an outer frame decorative aluminum 30 , and the outer side of the second outer frame pressed aluminum 29 is installed with the outer frame decorative aluminum 30 .

[0065] Furthermore, in a preferred embodiment, the window frame profile 1 also includes: an outer frame sealing strip 31, and the inner edge of the indoor side of the second outer frame pressed aluminum 29 is installed with the outer frame sealing strip 31. When the window sash profile 2 is in a closed state, the outer frame sealing strip 31 is against the outdoor side of the outer aluminum profile 25 of the window sash. The outer frame sealing strip 31 is used to seal between the window frame profile 1 and the window sash profile 2.

[0066] A double-break bridge door and window comprises the novel double-break bridge composite profile mentioned above, wherein both the window frame profile 1 and the window sash profile 2 are installed with sash glass.

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the implementation and protection scope of the present invention.

[0068] The present invention also has the following implementation modes based on the above:

[0069] In a further embodiment of the present invention, Figures 1 to 3The figure shows a horizontal cross-sectional view of the Diamond 95 double-broken-bridge system window based on a double-broken-bridge structure design, which includes: a cross-sectional schematic diagram of the position of the fixed sash side outer frame profile 101, a cross-sectional schematic diagram of the position of the middle frame profile 102, and a cross-sectional schematic diagram of the position 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 window sashes. After glass is installed in the window sash profile 2, a window sash is formed. The window sash and the window frame on the opening sash side are opened and closed in the form of casement or top-hung methods through hardware.

[0070] The cross-section of the upper fixed frame and the lower fixed frame on the fixed fan side is the same as the structure of the fixed fan side outer frame profile 101, so the cross-section diagram of the upper fixed frame and the lower fixed frame on the fixed fan side is not supplemented. The cross-section of the upper fixed frame and the lower fixed frame on the open fan side is the same as the structure of the open fan side outer frame profile 103, so the cross-section diagram of the upper fixed frame and the lower fixed frame on the open fan side is not supplemented.

[0071] The upper and lower frames of the window sash are the same in the left and right directions, so the cross-sectional views of the upper and lower frames of the window sash were not added.

[0072] In a further embodiment of the present invention, Figures 4 to 6 The figure shows a horizontal cross-sectional view of the Diamond 110 double-broken-bridge double-inward-opening system window based on a double-broken-bridge structure design, which includes: a cross-sectional schematic diagram of the position of the fixed sash side outer frame profile 101, a cross-sectional schematic diagram of the position of the middle frame profile 102, and a cross-sectional schematic diagram of the position 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; a window frame for installing window sashes is formed between the middle frame profile 102 and the opening sash side outer frame profile 103. After glass is installed in the window sash profile 2, a window sash is formed. The window sash and the window frame on the opening sash side are opened and closed in the form of casement or top-hung opening modes through hardware.

[0073] The cross-section of the upper fixed frame and the lower fixed frame on the fixed fan side is the same as the structure of the fixed fan side outer frame profile 101, so the cross-section diagram of the upper fixed frame and the lower fixed frame on the fixed fan side is not supplemented. The cross-section of the upper fixed frame and the lower fixed frame on the open fan side is the same as the structure of the open fan side outer frame profile 103, so the cross-section diagram of the upper fixed frame and the lower fixed frame on the open fan side is not supplemented.

[0074] Compared with the Diamond 95 double-break bridge system window, the Diamond 110 double-break bridge double inward-opening system window is equipped with a first frame external pressed aluminum 28, a frame external decorative aluminum 30 and a frame external sealing strip 31. By adding the first frame external pressed aluminum 28, the frame external decorative aluminum 30 and the frame external sealing strip 31 on the outdoor side, the wind pressure resistance and sealing performance of the window can be effectively improved, and it is suitable for large-size aluminum profile doors and windows.

[0075] The upper and lower frames of the window sash are the same in the left and right directions, so the cross-sectional views of the upper and lower frames of the window sash were not added.

[0076] In a further embodiment of the present invention, Figures 1 to 7 As shown, by designing the indoor sealing strip 26, the main sealing strip 17, the outdoor sealing strip 18 and the frame outer sealing strip 31 from the indoor side to the outdoor side, multiple seals are achieved at the opening and closing positions of the window sash and the window frame, and the multiple sealing strips work together to achieve functions such as thermal insulation, sound insulation and noise reduction.

[0077] In a further embodiment of the present invention, a double-broken bridge window frame profile 1 composed of a first plastic profile 12, a first broken bridge connecting profile 13 and a second plastic profile 14 and a double-broken bridge window sash profile 2 composed of a third plastic profile 22, a second broken bridge connecting profile 23 and a fourth plastic profile 24 are used to form two sections of thermal insulation bridges inside the aluminum profile, thereby effectively blocking the heat conduction path of the aluminum alloy material. This not only retains the lightweight characteristics of the aluminum alloy, but also improves its thermal insulation and sound insulation effects. Compared with a single-section thermal insulation bridge, it effectively improves the thermal insulation and sound insulation performance, effectively slows down the loss of heat, and has significant advantages in thermal insulation, heat insulation, sound insulation, energy saving and other aspects.

[0078] In a further embodiment of the present invention, a third strip clamping portion 132 is provided on both the inner and outer sides of the first thermally-broken bridge connecting profile 13. When the window frame profile 1 is installed in the wall opening, the third strip clamping portion 132 located on the outer periphery of the window frame can cooperate with the first support portion 111 and the second support portion 151 to support the combined doors and windows based on the double thermally-broken bridge structure design, and the first thermally-broken bridge connecting profile 13 is located at the installation position of the glass, and the third strip clamping portion 132 located on the inner periphery is against the outer edge of the glass, which can directly support the glass and transfer the stress applied by the glass to the window frame profile 1 to the wall, thereby reducing the influence of the quality of the large-size glass on the window frame profile 1 and improving the overall strength of the window frame profile 1. The design based on the double thermally-broken bridge structure can be used to design large-size aluminum profile doors and windows.

[0079] In a further embodiment of the present invention, a third strip-shaped clamping portion 132 is provided on both the inner and outer sides of the first thermally-broken bridge connecting profile 13. The third strip-shaped clamping portion 132 located on the inner periphery abuts against the outer edge of the glass, and the third strip-shaped clamping portion 132 located on the inner periphery abuts against the wall opening, which can directly support the glass and transfer the stress exerted by the glass on the window frame profile 1 to the wall. At the same time, a thermally-broken bridge structure is separately provided on the outdoor side and the indoor side. Based on the double thermally-broken bridge structure design, the heat conduction path of the aluminum alloy material is effectively blocked.

[0080] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
