[0003] Chinese patent application CN201910713031.4 discloses a column, window frame structure, and window. The column is a split structure, which avoids the need for multiple integral columns on the window frame and sash. Replacing the multiple integral columns in the prior art with split columns reduces aluminum alloy material consumption by up to 35% compared to existing technologies. Furthermore, due to the split column structure, the window frame and sash can be installed simultaneously on-site and fixed at the junction of the first and second split columns, improving on-site installation efficiency. However, in this window structure, the sash and the outer side of the window frame are fitted together, making it impossible to observe whether the interior is completely tight. During the installation of the sash and frame, misalignment can easily occur, creating gaps that allow heat exchange between the inside and outside of the window, affecting the window's thermal insulation performance.
