Description

Technical Field

[0001] This utility model relates to the field of building exterior window processing technology, specifically to an aluminum alloy window assembly corner connection device. Background Technology

[0002] The corner assembly process for doors and windows, also known as the corner connection process, involves the overlapping of frames and sashes. The frame is made up of frame profiles joined at 45° angles, and the sash is made up of sash profiles joined at 45° angles. The key to connecting the profiles lies in the corner splicing. The corner splicing process requires corner brackets and corner steel plates as connectors. After the corner assembly process is completed, glue is applied to firmly fix the corner connectors and the frame and sash structural profiles.

[0003] As disclosed in the existing patent (application number CN201820300510.4) regarding a heat-insulated aluminum alloy system door and window frame corner glue injection connection structure: it includes adjacent outdoor frames and indoor frames, each with an independent indoor and outdoor cavity. Indoor and outdoor corner brackets are fixed to the indoor and outdoor cavities of the indoor frame, respectively, with their ends inserted into the indoor and outdoor cavities of the outdoor frame. Several glue injection holes are provided on both the outdoor and indoor frames. It also includes glue injection angle steel pieces.

[0004] The existing technical problems are as follows: During processing, the two frame (or sash) structural profiles are cut at a 45-degree angle, and indoor and outdoor corner brackets are inserted between them. Then, angle steel plates are inserted and finally glued together. The whole construction process is complicated and inefficient. At the same time, each component is assembled separately, resulting in uneven stress and misalignment of the corners. In addition, the corners of the profiles are damaged during the transportation of doors and windows. The corners are easy to pull apart during installation and leak air / rain / light during use, resulting in frequent repairs. Moreover, the repairs are difficult and the results are not obvious.

[0019] An inner edge banding strip 4 is fixed on the side of the corner bracket connector 3 closest to the interior, and an outer edge banding strip 5 is fixed on the side of the corner bracket connector 3 closest to the exterior. The inner edge banding strip 4 and the outer edge banding strip 5 are parallel to the direction of the corner bracket connector 3. The purpose of the inner edge banding strip 4 and the outer edge banding strip 5 is to cover the splice seam of the profile. After the subsequent glue injection operation, the inner edge banding strip 4 and the outer edge banding strip 5 are bonded to the profile into a whole. The finishing shape of the inner edge banding strip 4 and the outer edge banding strip 5 is windproof, rainproof, and lightproof. It has high sealing performance and a comfortable and high-end visual appearance, reducing maintenance costs.

[0020] Furthermore, the inner wall of the outer sealing strip 5 is fixed with a set of angle steel plates 6. The set of angle steel plates 6 does not need to be installed separately, which improves the efficiency of the work. The fixing method can be fixed by snap-fit ​​or welding.

The top end of the corner bracket connector 3 is fixed with multiple profile groove protrusions 3.4, which correspond one-to-one with the profile grooves 7 of the frame and sash structure profile 10.

[0023] The corner bracket connector 3 is clamped between the splice seams of the two frame sash structural profiles 10.

[0024] Furthermore, the bottom ends of the inner edge banding 4 and the outer edge banding 5 are rounded, which can effectively prevent the corners of the profile from being damaged during transportation.

[0025] The specific operation process of this embodiment is as follows: 1. Profile preparation: According to the optimization order, select the corresponding frame and fan structure profile 10, place it flat on the cutting table, adjust the blade angle, output the pressure block to press the profile, cut the material with double blades at 45 degrees, check the cutting size and angle after cutting, and clean the aluminum chips generated after cutting with an air gun. Then, use a roller to evenly apply cross-section glue to the aluminum wall of the end face of the frame and fan structure profile 10.

[0026] 2. Angle Combination: The device is placed between two frame and sash structural profiles 10 to be spliced. Then, the indoor corner bracket 1 and the outdoor corner bracket 2 of the device are inserted into the indoor cavity 10.1 and the outdoor cavity 10.2 of the frame and sash structural profiles 10 on both sides, respectively, so that the corner bracket connector 3 is clamped and fixed between the two frame and sash structural profiles 10. The corner bracket connector 3 provides a comprehensive assembly function for the corner connection process, and the one-piece cast corner has higher strength. The biggest advantage is that the processing and assembly are more convenient and faster, which improves work efficiency while ensuring and improving the sealing effect. 3. Glue injection: After assembling the corners, clean the surface impurities of the aluminum window corners. Make corresponding injection holes at the outer corners of the frame and sash structural profile 10, and use a two-component glue gun to inject two-component glue into these holes. The frame and sash structural profile 10, corner bracket connector 3, and corner steel plate 6 are all made of rigid aluminum. Using flexible two-component glue fills all gaps and gaps, ensuring a completely tight corner connection. After the two-component glue solidifies, the corner sealing and corner strength reach their optimal state. 4. Finished product: After the corner joints are glued, the outer edge sealing strip 5 and the inner edge sealing strip 4 cover the splicing seams, making the corners tightly sealed. The exposed corner joints are all covered by the inner and outer edge sealing design, which is both beautiful and functional.
