Built-in densely-distributed column type double-layer corrugated steel plate composite shear wall

The invention discloses a built-in dense column type double-layer corrugated steel plate composite shear wall, and belongs to the technical field of structural engineering. The structure is composed of a prefabricated steel framework part and a concrete part poured on site. A prefabricated steel framework part comprises front and rear horizontal corrugated steel plates, upper and lower edge T-shaped steel beams and a plurality of built-in steel pipe columns densely distributed between the two corrugated steel plates. Horizontal strip-shaped plug welding seam holes are formed in the front corrugated steel plate and the rear corrugated steel plate and used for being connected with built-in densely-distributed plunger welding seams. The front and rear corrugated steel plates and the built-in densely-distributed columns are in welded connection with the upper and lower T-shaped steel beams; bolt holes are formed in webs of the upper T-shaped steel beam and the lower T-shaped steel beam. Concrete pouring holes are
