Abstract
Abstract In a climbing scaffolding or in a climbing formwork a guide rail (11) for the sole purpose of guiding the scaffolding during the lifting and lowering movements is provided, which is detachably secured to the concrete wall by at least two mounting parts (3, 4) for the climbing scaffolding section (6). This allows rapid lifting, and instead of a crane a lifting gear which is supported on the mounting parts can also be used for lifting.

Total Claims: 17
Claim 1
Independent Claim
159 words
In a climbing scaffolding device, said scaffolding device being attachable to a wall of a structure: a scaffolding platform, framework means for supporting said scaffolding platform, connecting means for attaching said framework means to said wall, the improvement comprising: said connecting means including at least two projections extending from and supported by said wall, said projections being spaced apart vertically, said framework means comprising an engaging member that may be attached to either of said projections, said framework means being constructed and arranged to enable it to be detached from one of said projections, moved to a position adjacent the other of said projections, and then attached to said other projection, and guide means separate from and in addition to the engaging member for guiding the framework means between said projections while the framework means is being moved from the one to the other of said projections, said guide means extending between and being removably attached to said projections.
