PROBLEM TO BE SOLVED: To provide a method and device for automatic elevation and sink of provisionally installed members easily along the outer side surface of a building while the structure remains simple. SOLUTION: A guide frame 2 and an elevating base member 3 are engaged slidably relative to each other in the vertical direction, and a screw shaft 16 rotated by a motor 14 is supported by one of them 2 and 3 rotatably in the vertical direction while a nut 20 to admit fitting-in of the screw shaft 16 is fixed to the other. Provisionally installed members 31 and 41 are attached to either of the guide frame 2 and base 3, either of which is engaged with the building frame 10 and the other is elevated and sunk with the regular or reverse rotation of the motor 14, and this operating cycle is repeated alternately so that the provisionally installed members 31 and 41 are elevated and sunk along the outer side surface of the building. Owing to simple elevating/sinking mechanism using the screw shaft 16 and nut 20, the whole device can be constructed compact and light, and it is possible to facilitate the fine adjustment of the positions where the members 31 and 41 are installed.
