PROBLEM TO BE SOLVED: To provide scaffolding for use in constructing a concrete structure which is erected by successively pouring concrete and has a tilted central axis, wherein the scaffolding need not be of a large scale and contributes to efficient construction work. SOLUTION: According to the structure of the scaffolding, existing blocks 1a, 1b each have a plurality of brackets 11a, 11b fixed thereto, and the brackets 11 have hanging members 13a, 13b engaged therewith, respectively. Further a frame body 12 is hung by the hanging members 13 in a manner enclosing the periphery of an arched rib. The frame body 12 is hung by ones 13a of the long and short hanging members, and easily elevated by raising the other hanging members 13b by jacks 21. The frame body 12 has a plurality of rollers 14 attached thereto, which abut on a peripheral surface of the existing block 1 and roll on the same when the frame body 12 is hoisted upward. Thus an interval between the frame body 12 and the peripheral surface of the existing block 1 is held as appropriate, and therefore the frame body 12 is stably moved upward along the peripheral surface.
