A universal scaffolding steepness controller is provided to reduce the installation time and the preparation process according to the formation of the screw loader attached with the steepness control knob. A universal scaffolding steepness controller for the work on ladders(1) is composed of hinges(10) having each nut hole at the upper and lower parts to be combined with nuts of a support rod(15) formed at left and right sides of the ladder; a scaffolding support rod(2) where nut holes are each formed at the end of both side surfaces of the upper part, a nut hole is formed to inject each screw loader(3) only at one side of the lower end, and a separation prevention rod(26) is each formed at the right and upper/lower sides to prevent the scaffolding from being separated; the screw loader attached with a steepness control knob(5) at the upper part to pass through a scaffolding support rod guide(7) formed at one side surface of the lower end of the scaffolding support rod, to have the lower part shaped like "T", and to easily control the height; a bearing body(4); a fixing rod(46); and an aluminium scaffolding(8) formed with holes(23) with a predetermined interval to be screwed up by combining bolts(6) at both ends, formed with a knob(22) for movement, and formed with three holes(16) in which a safety support rod(24) is inserted with a predetermined interval.
