ている。2. Description of the Related Art In recent years, sludge digestion tanks have been increasing in size, and have a height of 30 m or more and a maximum diameter of 20 m.
An egg-shaped digester with a capacity of 10,000 m 3 or more has been built. The egg-shaped digester is a prestressed concrete structure having an egg-shaped outer shape, and is excellent both structurally and functionally. However, when performing anticorrosion work on the wall surface of the concrete skeleton or installing pipes and the like, scaffolding work is being sought due to the large skeleton having a curved surface.

径が異なるため、壁面側の足場形状が不規則なものとな
り、安全管理上の点においても問題となる。That is, when a total scaffold is assembled inside a building, the height of the pipe scaffold becomes uneven because the base surface of the scaffold has an inverted conical shape, which complicates assembly and dismantling work. Since the planar shape of the building is circular and the radius varies depending on the height, the shape of the scaffold on the wall surface becomes irregular, which is a problem in terms of safety management.

For example, Japanese Patent Application Laid-Open No. 62-99557 discloses a mast that is provided inside a building and a winch provided on the top of the mast. Out mast guided up and down along a swivel, a swivel supported rotatably at the top of the out mast, a fixed scaffold mounted horizontally on the swivel, and a slide slidably supported by the fixed scaffold A scaffolding device for internal construction comprising a scaffold has been proposed.

ものである。In the scaffolding device described in the above publication, the height of the swivel is determined by moving the outmast and the swivel up and down by an electric winch, and the fixed scaffold is positioned by being rotated by a swivel motor attached to the swivel. After that, the slide scaffold is manually expanded and contracted to face the wall surface to be worked.
