Shelf foothold null of the large-sized building which possesses the large

摘要

PURPOSE:To make it possible to freely move on a shelf scaffold and safely and effectively work by forming shelf scaffolds in a ring shape above the large space of a large building. CONSTITUTION:A large space 33 is formed in a cylindrical large building 31. In the next step, a roof 45 is structured by structural steel skeletons 43 comprising H steels above the large space 33. Then, a shelf scaffold 49 for work is provided above the large space 33 of the large building 31. The shelf scaffold 49 is fixed below the structural steel skeletons 43 and 47, which is arranged above the large space 33 and along the structural steel skeletons 43 and 47. In working near the shelf scaffold 49, workers can freely come and go between each ring-like scaffold, which is provided concentrically through connecting scaffolds, by wandering the ring-like scaffolds from place to place.
