Cold-formed steel tube bundle shear wall adopting flanging build-in technology

The invention discloses a cold-formed steel tube bundle shear wall adopting an edge folding built-in process, which belongs to the technical field of structural engineering and is formed by sequentially connecting a plurality of box-shaped steel tube units. The steel pipe unit is formed by splicing cold-formed section steel and is provided with a cavity. The cold-formed section steel is processed to form various complex section shapes, and the section shapes enable the cold-formed section steel to form a closed box-shaped section through splicing. The splicing mode of the cold-formed section steel is folded edge built-in connection, and the built-in connection mode comprises applying extrusion built-in or arranging self-tapping screws. Concrete can be poured in the cavity at intervals, and the concrete can be common concrete, high-strength concrete, lightweight aggregate concrete or self-compacting concrete. The cold-formed steel tube bundle shear wall adopting the folded edge build-in process is high in asse
