Abstract

A scaffolding enclosure for use with large structures such as water towers and the like is described. The scaffolding has a modular construction and is adapted to provide one or more enclosed work areas against the walls of the structure. The scaffolding has a movable horizontal top module, preferably extending from one side of the structure to the other, and a vertical module at one end or preferably both ends of the horizontal top module, extending downwardly therefrom adjacent the wall of the structure. Each vertical module has at least one work area and is enclosed on the back and the sides. The front face is open to the wall of the structure, and the edges of the work area are sealed against the wall of the structure. For water towers with undercut lower walls, inwardly angled lower modules may be attached to the vertical modules, the lower modules also having at least one work area.

Claims8

Dependent claims

For use in blasting, painting or otherwise treating at least the vertical wall of a structure which is circular in cross-section and which has a central vertical axis, where said treatment is to take place in a substantially enclosed environment, a containment scaffolding comprising:

a generally horizontal module positionable on top of said structure and rotatable about said vertical axis, extending across said structure and having opposite end portions, at least one of which extends slightly outwardly beyond said wall;
a vertical module connected to and depending from at least one said extending end portion of said generally horizontal module, in close proximity to said wall, each said vertical module defining at least one work area adjacent said vertical wall, each said work area having enclosed top, bottom, rear and side faces and an open front face facing said vertical wall;
and
sealing mean at the edges of said open front face of each work area, adapted to contact the surface of said vertical wall and to effect a seal between said work area and said vertical wall.
