Combined stair step formwork supporting device for hoisting

The utility model relates to a combined stair step formwork supporting device for hoisting. The combined stair step formwork supporting device for the hoisting effectively solves the problems that a formwork is prone to deformation, small in rigidity, poor in forming quality, low in working efficiency and poor in applicability and generality. The combined stair step formwork supporting device for hoisting is characterized in that stair plate pressing bars are fixed to the lower portions of stair plate connecting pieces, the stair plate pressing bars are fixed to stair plates, the stair plate connecting pieces are arranged in the mode that every two stair plate connecting pieces are arranged in a left-and-right symmetrical mode and are distributed evenly from top to bottom, the every two stair plate connecting pieces in the left-and-right symmetrical mode are respectively connected with the two ends of the corresponding stair plate pressing bar respectively and are connected with the two ends of the correspond
