Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum alloy door and window installation technology, and in particular to a novel 90-degree corner tube structure for aluminum alloy doors and windows. Background Technology
[0002] Currently, the existing method for making 90-degree corners in aluminum alloy doors and windows usually involves pre-drilling holes of different sizes in the window frame, then connecting the window frame to the 90-degree corner tube with self-tapping screws, and finally applying adhesive and smoothing the exterior side to prevent water damage.
[0003] However, this method has several problems in practice: First, pre-drilling large and small holes in the door and window frames weakens the strength of the rods; second, sealing the large holes on the outside of the window frame with decorative covers poses a risk of water leakage or seepage; third, the decorative covers are made of PU plastic, which is prone to aging or falling off, affecting the appearance of the exterior windows (especially the operable sashes); and fourth, the installation position of the decorative covers is very likely to interfere with the installation position of the door and window hardware, affecting the normal installation of the hardware.
[0004] In addition, the use of self-tapping screws to fasten and connect the window frame and corner tubes, with a spacing of about 400mm between each adjacent screw, makes the window frame and other components prone to warping and deformation when the screws are tightened. This not only affects the appearance but also poses a risk of water leakage.
[0005] To address the aforementioned issues, a novel 90-degree corner tube structure for aluminum alloy doors and windows has been designed. Utility Model Content
[0006] This application provides a novel 90-degree corner tube structure for aluminum alloy doors and windows to solve the problem that existing methods for making 90-degree corners in aluminum alloy doors and windows typically involve pre-drilling holes of varying sizes in the window frame, which affects the stress on the members and weakens their strength.
[0007] Firstly, a novel aluminum alloy door and window 90° corner tube structure is provided, including:
[0008] The corner tube body has a first mounting surface, a second mounting surface and a third mounting surface for splicing window frames, and the included angle between the first mounting surface and the second mounting surface is 90°.
[0009] A window frame 1 is spliced onto both the first and second mounting surfaces, and a window frame 2 is spliced onto the third mounting surface;
[0010] A corner tube pressure plate is snapped between the second window frame and the two first window frames. The corner tube pressure plate is connected to the second window frame and the two second window frames respectively by bolts.
[0011] In some embodiments, the two window frames are arranged perpendicularly to each other, and the second window frame is located between the two window frames.
[0012] The first window frame and the second window frame are formed by splicing together multiple aluminum alloy window frames.
[0013] In some embodiments, the corner tube pressure plate includes an abutment plate, on which two connecting pieces are disposed opposite each other. The abutment plate is spliced with the second window frame, and the connecting pieces are fitted with the corresponding first window frame.
[0014] Both the abutment plate and the first window frame are provided with matching bolt holes, and both the connecting piece and the adjacent second window frame are provided with matching bolt holes. Bolt holes one and bolt holes two are used for installing bolts.
[0015] In some embodiments, waterproof sealant is provided between the joint between the first mounting surface and the first window frame, and between the joint between the second mounting surface and the first window frame.
[0016] In some embodiments, a snap-on cover is also included, which is snapped onto the side of the corner tube pressure plate away from the window frame.
[0017] In some embodiments, the cover includes a cover plate with two locking strips disposed opposite each other on the cover plate, and inclined plates are provided at both ends of the cover plate, the inclined plates abutting against one end of the connecting piece;
[0018] The abutment plate has a cavity inside, and a slot is provided inside the cavity. The locking strip is engaged inside the slot.
[0019] In some embodiments, the bolt is a mullion screw.
[0020] This application provides a novel 90-degree corner tube structure for aluminum alloy doors and windows. By using a first mounting surface, a second mounting surface, a third mounting surface, a corner tube pressure plate, and bolts, it eliminates the need for pre-drilling holes in the door and window frame, maintaining the integrity and load-bearing performance of the members, thereby enhancing the overall structural strength of the doors and windows.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] This application provides a novel 90-degree corner tube structure for aluminum alloy doors and windows, which solves the problem that existing methods for making 90-degree corners in aluminum alloy doors and windows typically involve pre-drilling holes of varying sizes on the window frame, affecting the stress on the members and weakening their strength.
[0031] Please see Figures 1-3 A novel 90-degree corner tube structure for aluminum alloy doors and windows includes: a corner tube body 1, which has a first mounting surface 11, a second mounting surface 12, and a third mounting surface 13 for splicing window frames, with an included angle of 90° between the first mounting surface 11 and the second mounting surface 12; window frames 1-2 are spliced on both the first mounting surface 11 and the second mounting surface 12, and window frames 2-3 are spliced on the third mounting surface 13; a corner tube pressure plate 4 is snapped between the window frames 2-3 and the two window frames 1-2, and the corner tube pressure plate 4 is connected to the window frames 2-3 and the two window frames 2-3 respectively by bolts 5.
[0032] The working principle of this new type of aluminum alloy door and window 90-degree corner tube structure is mainly based on modular splicing and fastening principles.
[0033] First, place the corner tube body 1 at the required installation position. The 90° angle between its first mounting surface 11 and second mounting surface 12 ensures the precise angle at the corner of the door or window.
[0034] Next, window frame 2 is spliced and installed on the first mounting surface 11 and the second mounting surface 12 of the corner tube body 1, respectively, to ensure a tight fit and accurate alignment between the window frame and the corner tube body. At the same time, window frame 3 is installed on the third mounting surface 13 of the corner tube body, forming the other side of the corner structure.
[0035] Corner tube clamping: Subsequently, the corner tube clamping plate 4 is clamped between the two window frames 1 2 and Window Frame 2 3. The design of the corner tube clamping plate allows it to be tightly embedded in and fixed to these window frames, ensuring a secure connection between them.
[0036] Finally, bolts 5 are used to connect and secure the corner tube pressure plate 4 to window frame 2 3 and the two window frames 2 1 respectively. The tightening force of the bolts makes the entire corner structure more robust and reliable, capable of withstanding various external forces and wind pressure.
[0037] In summary, this structure eliminates the need for pre-drilling holes in the door and window frames, maintaining the integrity and load-bearing capacity of the members, thereby enhancing the overall structural strength of the doors and windows.
[0038] The tight connection between the corner tube pressure plate and the window frame, as well as possible waterproof sealing treatments such as injecting waterproof sealant, effectively prevent moisture from seeping into the connection area, thus improving the waterproof performance of the doors and windows.
[0039] The modular splicing design between the corner tube body and the window frame simplifies the installation process, making installation faster and more convenient. At the same time, the snap-fit and bolt-fastening method of the corner tube pressure plate also improves installation efficiency.
[0040] The seamless connection between the corner tube structure and the window frame maintains the neatness and beauty of the door and window appearance, avoiding problems such as the aging and falling off of decorative covers that may occur in traditional installation methods.
[0041] This structure is suitable for different types of aluminum alloy doors and windows and corner requirements, offering strong flexibility and customizability.
[0042] Specifically, such as Figure 4 As shown, in this embodiment, the two window frames 1 2 are arranged vertically, and the window frame 2 3 is located between the two window frames 1 2; the window frames 1 2 and the window frame 2 3 are formed by splicing together multiple aluminum alloy window frames.
[0043] Preferably, in one embodiment, the corner tube pressure plate 4 in this embodiment includes an abutment plate 41, on which two connecting pieces 42 are disposed opposite to each other. The abutment plate 41 is spliced with the second window frame 3, and the connecting pieces 42 are fitted with the corresponding first window frame 2. The abutment plate 41 and the first window frame 2 are both provided with mutually compatible bolt holes 51, and the connecting pieces 42 and the adjacent second window frame 3 are both provided with mutually compatible bolt holes 52. The bolt holes 51 and 52 are used to install bolts 5.
[0044] The corner tube pressure plate 4 is a key component for connecting and fixing the two window frames 1 2 and Window Frame 2 3, ensuring the stability of the door and window corner structure.
[0045] The abutment plate 41 of the corner tube pressure plate 4 is placed above or to the side of the second window frame 3 and is tightly spliced with the second window frame 3. At the same time, the two connecting pieces 42 arranged opposite to each other on the abutment plate 41 are respectively attached to the inner or outer sides of the two first window frames 2.
[0046] The bolt holes 51 on the abutment plate 41 and the window frame 2 are aligned to ensure that the bolts 5 can pass through these holes and be tightened. Similarly, the bolt holes 52 on the connecting piece 42 and the adjacent window frame 3 are also aligned.
[0047] By passing bolts 5 through bolt holes 51 and 52 and securing them with nuts or other fasteners, the corner tube pressure plate 4 is firmly connected to window frame 2 and window frame 3. In this way, the corner tube pressure plate 4 serves to fix and enhance the stability of the corner structure.
[0048] Furthermore, this embodiment also includes a snap-on cover 6, which is snapped onto the side of the corner tube pressure plate 4 away from the window frame 2.
[0049] The cover 6 is an additional component of the corner tube pressure plate 4, mainly used to enhance the overall aesthetics of the corner structure and protect fasteners such as bolts from being directly exposed.
[0050] Specifically, the cover 6 described in this embodiment includes a cover plate 61, on which two locking strips 62 are arranged opposite each other. The cover plate 61 has inclined pieces 63 at both ends, and the inclined pieces 63 abut against one end of the connecting piece 42. The abutting plate 41 has a cavity inside, and the cavity has a locking groove arranged opposite each other, and the locking strips 62 are locked inside the locking groove.
[0051] Two locking strips 62 are provided opposite each other on the cover plate 61 of the snap cover 6. These locking strips match the slots in the cavity opened inside the corner tube pressure plate 4 abutment plate 41. During installation, the snap cover 6 is aligned with the corner tube pressure plate 4, so that the locking strips 62 can be smoothly inserted into the slots, thus achieving a stable connection between the snap cover 6 and the corner tube pressure plate 4.
[0052] The cover plate 61 of the snap cover 6 has inclined plates 63 at both ends. These inclined plates abut against one end of the connecting piece 42 of the corner tube pressure plate 4 during installation. This design helps to ensure that the snap cover 6 can fit tightly on the corner tube pressure plate 4 after installation, preventing loosening or falling off.
[0053] Because the cover 6 covers the side of the corner tube pressure plate 4 away from the window frame 2, it effectively conceals fasteners such as bolts installed through the bolt holes. This not only improves the aesthetics of the doors and windows but also reduces the risk of rust or damage that could result from directly exposed fasteners.
[0054] In another embodiment, waterproof sealant is provided between the joint of the first mounting surface 11 and the window frame 2, and between the joint of the second mounting surface 12 and the window frame 2.
[0055] The main function of the waterproof sealant is to fill the tiny gaps between the corner tube body 1 and the window frame 2, preventing external liquids such as moisture and rainwater from seeping into the interior of the door and window. This sealing effect is crucial for keeping the interior dry and preventing mold and corrosion.
[0056] In addition to its waterproofing function, the waterproof sealant can also enhance the stability of the connection between the corner tube body and the window frame to a certain extent. It can firmly bond the two components together, reducing loosening or displacement caused by vibration or external forces.
[0057] It should be noted that the bolt 5 in this embodiment is a mullion screw.
[0058] Molding screws are fasteners specifically designed for assembling doors and windows, possessing high strength and fastening performance. They can tightly connect components such as corner tube pressure plate 4, window frame 1 2, and window frame 2 3 together through a tight fit between the thread and the bolt hole.
[0059] Mitter screws are widely used in door and window installation. They can be selected in different lengths, diameters, and materials to meet the installation needs of doors and windows of different specifications and requirements.
[0060] Compared to traditional bolts, mullion screws have a smaller, more refined head design, maintaining a clean and aesthetically pleasing appearance after installation. They are also easier to conceal under the cover or other decorative components, minimizing their impact on the overall look.
