PROBLEM TO BE SOLVED: To improve the efficiency of the lift-up operation of a column member when a tower-like structure is constructed.SOLUTION: A construction device which constructs a tower-like structure by connecting a plurality of column members includes: a structure which forms an introduction space into which the column member is introduced and an upper space located above the introduction space; lifting/lowering means which includes a suspended frame on which the column member introduced into the introduction space is mounted and a suspension member which is connected to the suspended frame, and can lift up a connected body of the column members by the suspension member; guide means which guides the movement of the connected body during lift-up, in the upper space; and support means which is installed to the structure and releasably supports the connected body so that the connected body after lift-up does not fall. |
