[0038] This embodiment provides a large-span curtain wall column system, such as Figure 1-Figure 7 As shown, the large-span curtain wall column system includes an aluminum alloy column body 1, a main structure 2 and a connecting component 3. The aluminum alloy column body 1 is connected to the main structure 2 via the connecting component 3; the aluminum alloy column body 1 has a cavity 11 on the side facing the main structure 2, and the main structure 2 can be snapped into the cavity 11.

[0039] Specifically, the initial outline of the aluminum alloy column body 1 is a plate-like structure. When it needs to be processed into a large-span curtain wall column system, it needs to be pre-processed and milled in the factory to mill out the rear cavity of the column at the interlayer position, that is, on one side of the plate-like structure, a part in the middle is cut off to form a notch, which is the above-mentioned cavity 11. When matched with the main structure 2, the side of the main structure 2 can just be snapped into the cavity and contact with the upper and lower ends of the cavity 11 to avoid collision between the aluminum alloy column body 1 and the main structure 2.
