Description

Technical Field

[0001] The present invention relates to the field of door and window installation, and more specifically, to an aluminum alloy door and window installation mechanism and an installation method. Background Technique

[0002] As an important component of modern architecture, aluminum alloy doors and windows originated in the mid-20th century. With the development of the aluminum industry and the increasing demand for building lightweight, they gradually replaced traditional wooden and steel doors and windows. Its core technology is based on the lightweight, high-strength, and corrosion-resistant characteristics of aluminum alloy materials, combined with extrusion molding technology to achieve complex cross-section design, and through surface treatment technologies such as anodic oxidation, electrophoretic coating, or powder spraying to enhance weather resistance and decorative properties. After the 1980s, the introduction of broken bridge heat insulation technology effectively solved the problem of metal heat conduction, and cooperated with insulating glass to improve energy-saving performance, promoting its wide application in high-rise buildings and energy-saving buildings, becoming the mainstream door and window solution with both functionality and aesthetics; For the installation of aluminum alloy doors and windows, the frame needs to be fixed first: place the door and window frame into the opening and temporarily fix it. After adjusting the horizontal and verticality, fix it evenly with expansion bolts (spacing ≤ 500 mm), and fill the gap with foaming glue; then install the door and window sashes, pre-install the hardware and hang it into the frame, adjust the gap to 2 - 3 mm to ensure smooth opening and closing; then seal the inner and outer sides with neutral silicone sealant and waterproof rubber strips respectively, and embed the glass sealant strip; finally, install accessories such as anti-collision blocks and window screens, and comprehensively check the opening and closing flexibility, sealing performance, and firmness, with key control over the calibration accuracy, uniform stress, and anti-seepage treatment; Modern people tend to choose system windows more when decorating, mainly because of their superior comprehensive performance, scientific design, and ability to meet higher-quality living needs; however, system windows usually have a stable structure and are modularly designed, which will increase the difficulty of handling and positioning during installation. Especially for extra-large glass or special-shaped windows, the windows need to be calibrated online during installation. Due to their volume and weight, it is difficult to calibrate. If the wall is uneven or the measurement error is large, additional adjustments are required (such as adding gaskets or repairing the opening), and the safety is poor when the unfixed windows are adjusted back and forth.

[0003] To solve the above problems, an aluminum alloy door and window installation mechanism and an installation method are proposed in this application. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum alloy door and window installation mechanism and an installation method, which solve the problems in the prior art by using a lightweight outer frame for positioning first and then installing the window.

[0005] The purpose of the present invention can be achieved by the following technical solutions: An aluminum alloy door and window installation mechanism, including a window, further comprising: An outer frame, with a connection frame for connecting to the wall on its outer side and a positioning frame on its inner side. The outer frame is fixed to the wall by expansion screws; A connecting plate, one end of which is welded to the outer edge of the window, and the other end is bent into an L shape and embedded inside the outer frame. The horizontal section after bending is located between the two positioning frames; A screw, passing through the connection hole from the inner side of the window and abutting against the bent area of the connecting plate; A threaded sleeve, sleeved on the front end of the screw, with two symmetric locking plates hinged on its outer side. When the screw is rotated, the locking plates press against the outer surface of the window; In the above technical solution, the outer frame adopts a lightweight structure and is accurately fitted outside the window. The lightweight setting facilitates the adjustment of the outer frame and the wall during installation, making the operation more convenient. Using the reference of the outer frame and the wall to install the window, the window can be directly fixed to the outer frame without adjustment.

[0006] As a preferred technical solution of the present invention, connection frames flush with the end faces are formed at both ends on the outer side of the outer frame, and positioning frames flush with the end faces are formed at both ends on the inner side of the outer frame; In the above technical solution, the connection frame can strengthen the fixing effect between the outer frame and the wall, and the positioning frame provides a fitting space for the connecting plate, enabling the two to be connected in the internal space of the butt joint. The connection frame and the positioning frame being flush with the outer frame can ensure the aesthetics after installation while ensuring the function.

[0007] As a preferred technical solution of the present invention, avoidance frames flush with the end faces are formed at both ends on the outer side of the window. The positioning frame is connected to the avoidance frame, and the front and rear ends of the outer frame and the window are flush; In the above technical solution, the avoidance frame provides an installation space for the connecting plate and can also fit with the positioning frame for positioning the installation of the window in the outer frame.

[0008] As a preferred technical solution of the present invention, when the connecting plate is not bent, it is located inside the two avoidance frames. The connecting plate includes a fixed area and a bent area. The fixed area is welded and fixed to the outer side of the window and the avoidance frame, and the bent area is fitted with the inner side of the outer frame and is located between the two positioning frames after being formed; In the above technical solution, the connecting plate in the form of a bend is convenient for the assembly of the outer frame and the window before bending, can effectively increase the connection strength after bending, and the bending method is simple to operate.

[0009] As a preferred technical solution of the present invention, a connection hole penetrating the inner and outer sides is provided in the window. The connection hole is opposite to the bent area of the connecting plate, and the front end of the screw, the threaded sleeve, and the locking plates can pass through the connection hole when they are in a "one" - character alignment; In the above technical solution, the connection hole serves as the window for the final stable connection between the outer frame and the window and is located on the inner side of the window to achieve hidden connection.

[0010] As a preferred technical solution of the present invention, a positioning table capable of being inserted into the connection hole is fixed at one end of the screw, and a pressing cap with a diameter larger than the connection hole is fixed at the end of the positioning table away from the screw; In the above technical solution, after the positioning table is inserted into the connection hole, it can not only block the connection hole, but also provide support for the threaded sleeve and the locking plate, strengthening the overall strength after the structure is connected. The pressing cap is pressed against the inner side of the window.

[0011] As a preferred technical solution of the present invention, the locking plate is provided with a hinge hole at a non-symmetrical axis position for connection with the threaded sleeve, and the length of the locking plate is greater than the diameter of the connection hole; In the above technical solution, the locking plate is hinged to the threaded sleeve in an asymmetrical form. When the locking plate is loosened, it will rotate under its own action, facilitating the rotation of the locking plate. After rotation, the length of the locking plate is greater than the diameter of the connection hole, so as to achieve a supporting effect of preventing detachment outside the window.

[0012] As a preferred technical solution of the present invention, the locking plate is composed of two symmetrically arranged parts, and anti-slip ribs are formed on both surfaces along the rotation direction of the threaded sleeve; In the above technical solution, the two locking plates are symmetrically arranged to ensure uniform force, and the anti-slip ribs strengthen the friction with the window, preventing the threaded sleeve and the locking plate from following during the rotation of the screw.

[0013] As a preferred technical solution of the present invention, a fixing hole is penetrated through the outer frame, and the outer frame is fixed to the wall by passing an expansion screw from the inside to the outside through the fixing hole; In the above technical solution, the fixing hole penetrates from the inside to the outside of the outer frame, and the part of the expansion screw that does not penetrate the outer frame and enter the wall is accommodated between the two positioning frames.

[0014] The present invention also provides an installation method for aluminum alloy doors and windows. According to the above installation mechanism, the installation method includes the following steps: S1. Place the outer frame at the installation position on the wall, roughly adjust the position and drill holes in the wall. Pass the expansion screw through the fixing hole and knock it into the hole. Ensure the multi-angle levelness of the outer frame through a level. After tightening the expansion screw, the outer frame is fixed to the wall; S2. Place the window in the inner frame of the outer frame, make the avoidance frame and the connection frame end faces meet, and align the front and rear ends of the outer frame and the window to form a complete plane. At this time, use a tool to pass through the connection hole from the inside of the window outwards, and the front end of the tool abuts against the fixing area. Knock the other end of the tool until the fixing area enters between the two positioning frames and fits against the inner side of the connection frame; S3. Screw the threaded sleeve onto the front end of the screw, keep the locking plate and the screw in a straight line, and send the threaded sleeve, the locking plate and the front end of the screw into the space at the connection of the outer frame and the window through the connection hole. After the locking plate is completely sent in, it automatically rotates along the outside of the threaded sleeve under the action of asymmetry; S4. Pull the screw outwards so that the lock plate is perpendicular to the screw and fits against the outside of the window. At this time, rotate the screw. Under the screw-thread action of the screw and the threaded sleeve, the screw advances forward, while the threaded sleeve and the lock plate remain in place until the front end of the screw abuts against the bending area. Increase the torque, and the front end of the screw presses and fits the bending area against the inner side of the outer frame. The lock plate closely adheres to the outside of the window, and the positioning platform enters the connection hole during the rotation of the screw.

[0015] Advantages of the present invention: In the present invention, an outer frame is provided outside the window. The outer frame adopts a lightweight structure, and the installation gap between the inner side of the outer frame and the window coincides. When actually installing the entire door and window, the lighter outer frame is first fixed to the wall, thus avoiding the problem that it is difficult to adjust due to the heavy weight of the window, and the window can be directly installed with the outer frame without repeated adjustment. In the present invention, the provided connecting plate can be quickly pre-positioned by knocking when the window and the outer frame are butted. Then, the cooperation of the screw, the threaded sleeve, and the lock plate is used to support and position the outer frame and the window together with the connecting plate at the same time, which has the advantages of convenient operation and reliable structure.

[0020] At both ends of the outer side of the outer frame 1, connection frames 11 flush with the end faces are formed, and at both ends of the inner side of the outer frame 1, positioning frames 12 flush with the end faces are formed. After the outer frame 1 is fixed to the wall, polyurethane foam can be injected into the connection frames 11 to reinforce the connection with the wall.

[0021] Specifically, at both ends of the outer side of the window 2, avoidance frames 21 flush with the end faces are formed, the positioning frames 12 are connected to the avoidance frames 21, and the front and rear ends of the outer frame 1 and the window 2 are flush.

[0022] As an implementation manner of the present invention, after the outer frame 1 and the window 2 are installed as Figure 3 shown, the contact surfaces are in contact, and the front and back surfaces of the window are flush.

[0023] Specifically, when the connecting plate 3 is not bent, it is located inside the two avoidance frames 21. The connecting plate 3 includes a fixed area 31 and a bent area 32. The fixed area 31 is fixedly welded to the outer side of the window 2 and the avoidance frames 21, and the bent area 32 is in contact with the inner side of the outer frame 1 and is located between the two positioning frames 12 after being formed.

[0024] Specifically, the middle-opening window 2 is provided with a connection hole 22 penetrating through the inner and outer sides. The connection hole 22 faces the bending area 32 of the connecting plate 3. When the front end of the screw 4, the threaded sleeve 5, and the lock plate 6 are flush in a "one" shape, they can pass through the connection hole 22.

[0025] Specifically, a positioning platform 41 capable of being inserted into the connection hole 22 is fixed at one end of the screw 4, and a pressing cap 42 with a diameter larger than that of the connection hole 22 is fixed at the end of the positioning platform 41 away from the screw 4.

[0026] Specifically, the lock plate 6 is provided with a hinge hole 61 at a non-symmetrical axis position for connection with the threaded sleeve 5, and the length of the lock plate 6 is greater than the diameter of the connection hole 22.

[0027] Specifically, the lock plate 6 is composed of two symmetrically arranged parts, and anti-slip ribs 62 are formed on both surfaces along the rotation direction of the threaded sleeve 5.

[0028] Specifically, a fixing hole 13 is penetrated through the outer frame 1, and the outer frame 1 is fixed to the wall by passing the expansion screw 7 from the inside to the outside through the fixing hole 13.

[0029] The present invention also provides an installation method for an aluminum alloy door and window. According to the above installation mechanism, the installation method includes the following steps: S1. Place the outer frame 1 at the installation position on the wall, roughly adjust the position and drill holes in the wall. The expansion screw 7 passes through the fixing hole 13 and is knocked into the hole. Ensure the multi-angle levelness of the outer frame 1 through a level. After tightening the expansion screw 7, the outer frame 1 is fixed to the wall. S2. Place the window 2 in the inner frame of the outer frame 1, with the avoidance frame 21 and the end face of the connection frame 11 in contact. The front and rear ends of the outer frame 1 and the window 2 are aligned to form a complete plane. At this time, use a tool to pass through the connection hole 22 from the inner side of the window 2 outward. The front end of the tool abuts against the fixing area 31, and the other end of the tool is struck until the fixing area 31 enters between the two positioning frames 12 and fits against the inner side of the connection frame 11. This process is Figure 4 the state shown in a1 - a2; S3. As shown in the state of b1, the threaded sleeve 5 is screwed onto the front end of the screw 4, and the lock plate 6 and the screw 4 are kept in a straight line. The threaded sleeve 5, the lock plate 6, and the front end of the screw 4 are sent into the space at the connection of the outer frame 1 and the window 2 through the connection hole 22. As shown in the state of b2, after the lock plate 6 is completely sent in, it automatically rotates along the outside of the threaded sleeve 5 under the action of asymmetry; Figure 6 the state shown in b1; Figure 6 the state shown in b2; S4. Pull the screw 4 outwards so that the lock plate 6 is perpendicular to the screw 4 and fits against the outer side of the window 2. At this time, rotate the screw 4. Under the screw action with the threaded sleeve 5, the screw 4 advances forward, while the threaded sleeve 5 and the lock plate 6 remain in place until the front end of the screw 4 abuts against the bending area 32. Increase the torque, and the front end of the screw 4 presses and fits the bending area 32 against the inner side of the outer frame 1. The lock plate 6 closely adheres to the outer side of the window 2. During the rotation of the screw 4, the positioning table 41 enters the connection hole 22 accordingly, and finally forms the state as shown in Figure 4 a3 in Figure 6 and b3 in

[0030] It can be understood that the present invention adopts a lightweight outer frame design, and the installation gap between its inner side and the window fits precisely. When installing, the outer frame is first independently fixed to the wall, effectively solving the problem of adjusting traditional heavy windows. After pre-positioning by knocking the connecting plate, with the coordinated action of the screw, the threaded sleeve and the lock plate, the rapid and precise docking of the outer frame and the window is achieved. While synchronously completing the support and positioning, the installation efficiency and structural stability are significantly improved, and it has the advantages of convenient operation and high reliability.
