Abstract
The invention relates to a method for carrying out work on an object of shipbuilding or building construction or industrial installations by means of hanging stages or cradles, which are connected to the object by means of a plurality of U-shaped fixtures. For a long time this method has suffered from the disadvantage that subsequent welding, flexing, breaking away and similar work led to damage to adjacent surfaces. It was also necessary to dispose of the separated U-fixtures or irons. This problem is obviated by the invention in that waterproof, stainless base plates (10) are fixed in spaced manner to the object so as to remain permanently thereon and the fixtures (16) are fixed to the base plate (10) by means of a redetachable screw or plug-in connection (14) and following the detachment and removal of the reusable fixtures (16) from the base plate (10), the screw or plug-in connection (14) is closed.
