Description

Technical Field

[0001] The utility model relates to the technical field of installation of aluminum alloy doors and windows, in particular to a middle stile connection structure of a broken bridge aluminum alloy door and window. Background Technique

[0002] The broken bridge aluminum is also called heat-insulating broken bridge aluminum profile, heat-insulating aluminum alloy profile, broken bridge aluminum alloy, cold bridge-breaking profile, and broken bridge type aluminum-plastic composite profile. It has more excellent performance than ordinary aluminum alloy profiles and is used more and more widely due to its good performance.

[0003] The authorized announcement number is CN220226625U, which discloses a middle stile connection structure of a broken bridge aluminum alloy door and window. This patented technology realizes the corresponding fit of the mounting frame and the corresponding groove through the sliding groove and the sliding block on the side wall of the broken bridge aluminum alloy, by using structures such as the corresponding groove, the mounting frame, the adjustment groove, the mounting bolt, and the adjustment nut. Through the participation of the mounting frame in the middle stile connection, structures such as the clamp, the hook groove, the hook block, and the mounting groove are provided. The clamp is fixedly connected to the mounting frame by riveting, and with the fit of the connection groove and the clamp, while ensuring the stability and connectivity of the mounting frame, it can avoid affecting the width of the broken bridge aluminum alloy frame; however, in this solution, when the middle stile and the broken bridge aluminum alloy door and window are installed and fixed by bolts, there is a small axial tensile strength in the bolt connection. Bearing a strong axial load will increase the possibility of bolt joint failure. The bolt connection has a significant vibration impact.
