Assembling process of thermal-insulation aluminum alloy window frame

Abstract

The invention relates to an assembling process of a thermal-insulation aluminum alloy window frame. The assembling process of the window frame includes the steps that (1) a V-shaped notch of a side frame is formed through milling, and the end of a mullion is milled into a V shape; (2) one sides of corner pieces are inserted into and embedded into grooves in the outer side of the side frame; (3) the V-shaped end of the mullion is inserted into the V-shaped notch of the side frame, and meanwhile, the other sides of the corner pieces are inserted and embedded into grooves in the outer side of the mullion; (4) the corner pieces are glue-injected corner pieces and adhere to the outer surfaces of both the side frame and mullion through corner glue; and (5) screws are applied from the side frame into the mullion, so that the side frame and the mullion are fixed together. According to the assembling process, the structure is simple, and assembling is fast and convenient; all the connecting positions are neat, attractive, high in strength and free of leakage points, and sealing joint strips do not need to be disconnected, so that the common quality problems of exiting doors and windows are eliminated, and the air tightness and water tightness of a whole window are effectively improved; and meanwhile, manpower and material resources are saved, the applicability is high, and the economic value and the using effect are excellent.

Description

technical field [0001] The invention relates to an assembly process of a heat-insulating aluminum alloy window frame. Background technique [0002] The outstanding advantages of heat-insulated aluminum alloy doors and windows are high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life, good decorative effect, and the use of high-grade Aluminum alloy doors and windows with broken bridge partitions are the first choice for energy-saving building windows. They are widely used in real life. The frame and mullion assembly process of heat-insulating aluminum alloy doors and windows is still based on traditional European production methods. Aluminum alloy door and window sills are processed by cutting at 90° and then milling the tenon and groove with an end milling machine through riveting and screwing. This process has many disadvantages: [0003] 1. ...

AI Technical Summary

Problems solved by technology

[0003] 1. If figure 1 As shown, because the heat-insulating aluminum alloy door and window frames and stiles are installed with hardware and sealant strips, convex grooves are provided on the inside. When the stiles are combined with the frame and stiles, there will be gaps of uneven size. There is no good solution, which brings hidden dangers to the leakage of doors and windows, resulting in poor air tightness of the overall doors and windows; 2. figure 2 As shown, since the heat-insulating aluminum alloy door and window mullion is cut at 90°, when it is combined with the frame and the mullion, since the notch 100 of the sealing strip is straight and cannot communicate with the notch 100 of the transverse frame sealing strip, when installing the strip At this time, the sealing strip here must be disconnected and installed to form a broken right angle, which violates the specification that the door and window sealing strips must not be disconnected during installation, and this also greatly reduces the airtightness and watertightness of doors and windows; 3. Due to The mortise of the heat-insulated aluminum alloy door and window matching the sill and the frame and the sill is processed by an end milling machine. During the milling process, the milling cutter vibrates, and the machining accuracy of the sill cannot be guaranteed, which will form multiple leakage points, resulting in a gap between the frame and the stile. 4. Since the heat-insulating aluminum alloy door and window mullion is cut at 90°, there will be a gap of about 2.5mm between the notch of the frame sealing strip and the milling surface of the mullion. Even if a waterproof rubber pad is used, it is difficult to ensure This is also an important hidden danger of the common quality problems of aluminum alloy doors and windows; 5. Since the heat-insulating aluminum alloy doors and windows are milled with mortise and groove through riveting and screwing, single-sided riveting and screwing will affect the overall strength of doors and windows, so double-sided riveting is used , The screw connection will leave the riveted and screwed rivet socket and screw cap in the open position, which affects the appearance and brings inconvenience to the crimping installation process; Stile connectors, whether made of aluminum alloy or stainless steel, have an invisible impact on the cost of doors and windows; take German Schüco profiles as an example; 7. The strength of the gap between the traditional heat-insulating aluminum alloy door and window stile and frame, and the stile assembly and stability bring instability to the wind pressure resistance of the whole window, taking German Schüco profiles as an example
