Single-piece type vertical main frame attached scaffold

The utility model belongs to the technical field of building construction, particularly relates to a single-piece type vertical main frame attached scaffold, and solves the problems that when a framebody of an existing lattice type vertical main frame is used for installation in a narrow space, the construction difficulty is large, the efficiency is low, and potential safety hazards are generateddue to the fact that the frame body easily collides with an attached arm of a tower crane. The device comprises a vertical rod, a triangular support, a guide rail, a multifunctional upper lifting beam, a lower lifting beam, an electric hoist, a steel wire rope and a support, the two vertical rods are connected through a triangular support, and a guide rail is fixed to the outer side of one standcolumn. The guide wheels of the two brackets of the support are respectively clamped in the grooves of the guide rail; two pin shafts of the multifunctional upper lifting beam are sleeved with steering wheels, and the free end
