The invention relates to a circular hollow interlayer splicing column and a construction method thereof, and belongs to the technical field of building steel structure construction. The circular hollow interlayer splicing column comprises an outer circular pipe column formed by vertically inserting and fixing at least two skeleton units, and an inner circular pipe column member fixed in the outercircular pipe column; the inner wall of the outer circular pipe column is welded with at least one anti-drop groove; the inner tubular column member comprises an inner circular pipe column concentrically arranged with the outer circular pipe column, and a plurality of equal length steel partition plates welded perpendicularly along the outer wall of the inner circular pipe column; the steel partition plates are spaced apart from each other and anti-drop heads matched with the anti-drop grooves are arranged at ends of steel partition plates; the inner circular pipe column is fixed by insertingthe anti-drop heads of the steel partition plates into the anti-drop grooves of the outer circular pipe column; and the heights of the skeleton units at the left side and the right side of the bottomlayer is inconsistent in the vertical direction and the two skeleton units are staggered up and down. By adopting the circular hollow interlayer splicing column, the problems that the connection modeof the existing circular hollow interlayer splicing column is inconvenient in on-site construction operation, the connecting member is complicated in design and construction, and pitch points are insufficient in stiffness, and difficult in welding at present are solved.
