<p>Provision for fastening scaffolding for working on roofs is esp. applicable to flat roofs. A retaining plate (12), with dowels (13) anchoring it to the roof surface, has a tubular or threaded socket (11) and a round or sealing hood (10) acting in conjunction with this. This is firmly pressed onto the roof surface, with watertight effect, with the aid of a tubular spindle or eyebolt, comprising ring (20), threaded spindle (18) and extension piece (17). The hood can have a top hole for tubular spindle or eyebolt passage, and also a sealing edge and handle (19). Scaffolding can be quickly, easily and safely secured for work on a flat roof, without special fixtures on the building.</p> |
