Description

Technical Field

[0001] This utility model relates to the field of aluminum door and window reinforcement technology, and in particular to a wind pressure-resistant reinforcement structure for thermally broken aluminum doors and windows. Background Technology

[0002] When exploring the mechanism for improving the wind pressure resistance of thermally broken aluminum windows and doors, the rigor and scientific nature of their structural design are key factors. This window and door system uses high-strength aluminum alloy profiles as the frame material, a material renowned for its excellent mechanical properties and corrosion resistance, capable of withstanding strong wind pressure without deformation. Furthermore, the rational structural design of the frame further enhances its wind pressure resistance. To improve the wind pressure resistance of windows and doors, thermally broken aluminum windows and doors are often equipped with mullions, which, as the "core support" of the window and door structure, significantly enhance overall rigidity, especially in strong wind environments, effectively improving the stability of the windows and doors. For large-area windows, the reinforced use of mullions is particularly crucial to ensure the structural stability of the windows under strong winds.

[0003] The sealing system of thermally broken aluminum windows and doors uses high-quality EPDM rubber, which boasts excellent sealing performance and weather resistance. When the windows and doors are closed, the sealing strip effectively blocks wind and rain intrusion, ensuring the airtightness and watertightness of the windows and doors, thereby further enhancing their wind pressure resistance.

[0004] In addition to the structural features mentioned above, thermally broken aluminum windows and doors also enhance their wind pressure resistance through their unique thermal break design. This design achieves physical separation between the indoor and outdoor aluminum profiles by embedding low thermal conductivity thermal break strips (such as PA66 weather-resistant nylon thermal break strips) within the aluminum alloy profiles, forming a "thermal bridge" that effectively blocks heat transfer. This design not only improves the thermal insulation performance of the windows and doors but also further enhances their wind pressure resistance by strengthening the overall integrity of the frame.

[0005] The improved wind pressure resistance of thermally broken aluminum windows and doors is primarily due to the rigorous structural design, encompassing multiple components such as sealing strips, glass, and frames. Although the frame is constructed of high-strength, corrosion-resistant aluminum alloy profiles and features a rational structural design to withstand significant wind pressure, additional reinforcement structures are sometimes necessary to further enhance wind pressure resistance. Reinforcing ribs, as one reinforcement method, can improve the rigidity and stability of the window and door frame. However, if only a single reinforcing rib is used without the constraint of two separate window and door frame edges, localized stress concentration may occur under significant wind pressure, affecting the overall wind pressure resistance. Therefore, the design of two separate window and door frame edges can more effectively disperse wind pressure, reduce localized stress, and thus improve the overall stability of the windows and doors.

[0006] The main purpose of this utility model is to provide a wind pressure-strengthening structure for thermally broken aluminum windows and doors, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A wind pressure-resistant reinforced structure for thermally broken aluminum windows and doors includes a first frame, a second frame, a first insulation board, and a second insulation board, wherein the first frame and the second frame constitute the basic skeleton of the thermally broken aluminum windows and doors.

[0009] The first frame body has a protruding frame inside, and a first limiting strip is provided at the corner of the protruding frame. A first limiting groove for locking is formed between multiple first limiting strips. The middle section of the protruding frame has a pressing arc-shaped part, and an inner groove is formed inside the pressing arc-shaped part.

[0010] The second frame body has an inner protrusion inside, and a second limiting strip is provided at the corner of the inner protrusion. Multiple second limiting strips form a second limiting groove for locking. The middle section of the inner protrusion has an oblique support strip and a retaining strip. The oblique support strip is connected to an insertion strip through an arc-shaped cover. The insertion strip is inserted into the inner groove. The side wall of the arc-shaped cover has an opening mask and forms a perforation with the opening mask. The retaining strip is inserted into the opening of the opening mask. The oblique support strip, the insertion strip and the retaining strip form a reinforcing rib to enhance the thermal break aluminum window and door.

[0011] A first heat insulation plate is inserted and connected between one set of the first limiting groove and the second limiting groove, and a second heat insulation plate is inserted and connected between the other set of the first limiting groove and the second limiting groove. The heat insulation of the thermally broken aluminum doors and windows is achieved through the double-layer heat insulation plate.

[0012] In an optional embodiment of this application, the first frame body, the protruding frame, the first limiting strip, and the abutting arc-shaped part are designed as a single unit. The cross-section of the first limiting strip is designed in a "T" shape. Two parallel limiting strips are placed at the corner of the protruding frame.

Bolts are inserted to fix the first heat insulation plate and the second heat insulation plate to the inclined support strip.

[0015] In an optional embodiment of this application, the cross-section of the abutting arc-shaped part is designed in the shape of an "Ω" and the insertion strip is restricted by the inner groove to prevent it from falling off, thereby achieving a limiting connection between the first frame body and the second frame body.

[0016] In an optional embodiment of this application, the ends of the mask opening and the abutment strip are designed with a protruding arc shape. The abutment strip is embedded in the perforation by the protruding arc shape, so that the abutment strip and the oblique support strip are designed in a triangular shape, and the insertion strip and the abutment arc part are kept stable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 - Figure 5 As shown, a wind pressure-resistant enhancement structure for thermally broken aluminum windows and doors mainly consists of a first frame 11, a second frame 21, a first insulation board 3, and a second insulation board 4. These parts together form the basic framework of the thermally broken aluminum windows and doors, ensuring the overall stability and durability of the windows and doors.

[0030] Specifically, the first door / window frame 1 includes a first frame body 11, a protruding bracket 12, and a first limiting strip 13. The protruding bracket 12 is designed inside the first frame body 11, and the first limiting strip 13 is set at the corner of the protruding bracket 12. These first limiting strips 13 form first limiting grooves 14 for locking, making the entire structure more stable. The middle section of the protruding bracket 12 is designed with a clamping arc-shaped part 15, and its interior is also designed with an inner groove 16, further enhancing the stability and wind pressure resistance of the structure.

[0031] The second window frame 2 includes a second frame body 21, an inner protrusion 22, and a second limiting strip 23. Inside the second frame body 21, the inner protrusion 22 is designed, and a second limiting strip 23 is also provided at its corner. These second limiting strips 23 form a second limiting groove 24 for locking, which cooperates with the first limiting groove 14 to further improve the wind pressure resistance of the window. The middle section of the inner protrusion 22 is designed with a diagonal support strip 25 and a retaining strip 20. The diagonal support strip 25 is connected to an insertion strip 29 via an arc-shaped cover 26. The insertion strip 29 can be inserted into the inner groove 16, thereby achieving a stable connection between the two frame bodies. The side wall of the arc-shaped cover 26 is also provided with an opening mask 27, forming a through hole 28. The retaining strip 20 is inserted into the opening of the opening mask 27. The diagonal support strip 25, the insertion strip 29, and the retaining strip 20 together form a reinforcing rib, thereby achieving the strengthening effect of the thermally broken aluminum window.

[0032] In terms of thermal insulation, a first thermal insulation plate 3 is inserted and connected between a first limiting groove 14 and a second limiting groove 24, and a second thermal insulation plate 4 is inserted and connected between another first limiting groove 14 and a second limiting groove 24. Through the design of double-layer thermal insulation plates, the thermal insulation function of thermally broken aluminum windows and doors is effectively realized.

[0033] To further enhance structural stability and wind pressure resistance, the first frame 11, the protruding frame 12, the first limiting strip 13, and the abutting arc-shaped part 15 adopt an integrated design. The first limiting strip 13 has a "T"-shaped cross-section, and two parallel limiting strips are precisely placed at the corners of the protruding frame 12 to ensure structural stability. The surface of the first limiting strip 13 is also designed with anti-slip embossed strips to increase friction and prevent slippage.

[0034] Similarly, the second frame 21, the inner protrusion 22, and the second limiting strip 23 also adopt an integrated design. The oblique support strip 25, the arc-shaped cover 26, the opening cover 27, and the insertion strip 29 also adopt an integrated design. The oblique support strip 25 and the abutment strip 20 are precisely welded to the inner protrusion 22 to ensure structural stability. The structure of the second limiting strip 23 is consistent with that of the first limiting strip 13 to ensure overall coordination and stability.

[0035] The diagonal support strip 25, the arc-shaped cover 26, the opening cover 27, and the insert strip 29 serve as reinforcing ribs, and their side walls are provided with waist holes. These waist holes are directly opposite the screw holes on the first heat insulation plate 3 and the second heat insulation plate 4. By inserting bolts into these screw holes, the first heat insulation plate 3 and the second heat insulation plate 4 can be firmly fixed together with the diagonal support strip 25, thereby further improving the stability and wind pressure resistance of the structure.

[0036] To ensure a more secure limiting connection between the first frame 11 and the second frame 21, the cross-section of the abutting arc-shaped portion 15 adopts an "Ω" shape design. The inner groove 16 effectively restricts the movement of the insertion strip 29, preventing it from falling off, thus ensuring the stability and safety of the entire structure.

[0037] Finally, the ends of the opening 27 and the clamping strip 20 feature a protruding arc design. This design allows the clamping strip 20 to be embedded in the perforation 28, forming a triangular shape with the clamping strip 20 and the diagonal support strip 25. This ensures a more stable connection between the insert strip 29 and the clamping arc portion 15. This design not only enhances the structure's wind pressure resistance but also ensures the long-term stability and durability of the doors and windows.

[0038] Prepare all components of the first door / window frame 1, including the first frame body 11, the protruding bracket 12, and the first limiting strip 13. Install the protruding bracket 12 inside the first frame body 11, ensuring that the first limiting strip 13 is precisely positioned at the corner of the protruding bracket 12. First limiting grooves 14 for engagement will be formed between these first limiting strips 13. Next, design and install a retaining arc-shaped portion 15 in the middle section of the protruding bracket 12, with an inner groove 16 designed inside.

[0039] Prepare all components of the second door / window frame 2, including the second frame body 21, the inner protrusion 22, and the second limiting strip 23. After the inner protrusion 22 is installed inside the second frame body 21, the second limiting strip 23 is also installed at the corner. These second limiting strips 23 will form a second limiting groove 24 for locking, which cooperates with the first limiting groove 14. In the middle section of the inner protrusion 22, an inclined support strip 25 and a retaining strip 20 are designed and installed. The inclined support strip 25 is connected to the insertion strip 29 through the arc-shaped cover 26, ensuring that the insertion strip 29 can be smoothly inserted into the inner groove 16 of the first frame body 11. At the same time, an opening mask 27 is opened on the side wall of the arc-shaped cover 26, and a perforation 28 is formed with the opening mask 27.

[0040] Install the thermal insulation panels. Insert the first thermal insulation panel 3 between one set of first limiting grooves 14 and second limiting grooves 24, and insert the second thermal insulation panel 4 between another set of first limiting grooves 14 and second limiting grooves 24. The double-layer thermal insulation design achieves the thermal insulation function of the thermally broken aluminum windows and doors.

[0041] To enhance structural stability and wind pressure resistance, the diagonal support strip 25, the arc-shaped cover 26, the opening cover 27, and the insert strip 29 are used as reinforcing ribs, and their side walls are provided with recessed holes that align with the screw holes on the first heat insulation plate 3 and the second heat insulation plate 4. Bolts are inserted into these screw holes to securely fasten the first heat insulation plate 3 and the second heat insulation plate 4 to the diagonal support strip 25.

[0042] The limiting connection between the first frame 11 and the second frame 21 is ensured to be more stable. The cross-section of the abutting arc portion 15 adopts an "Ω" shape design, and the design of the inner groove 16 effectively restricts the movement of the insert strip 29 and prevents it from falling off. The ends of the opening mask 27 and the abutting strip 20 adopt a protruding arc design, embedding the abutting strip 20 into the through hole 28, so that the abutting strip 20 and the diagonal support strip 25 form a triangular design, ensuring a more stable connection between the insert strip 29 and the abutting arc portion 15. The reinforced structure for improving the wind pressure resistance of thermally broken aluminum windows and doors is now assembled.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
