<p>Procedure for the construction of a concrete shaft (10) for a platform or similar structure, where one or several of the shafts (10) will be outfitted with relatively much equipment. The shafts (10) are constructed of prefabricated sections (15; 15', 15'') which are consecutively installed butt-in-butt on top of each other and which are left in the shaft as an internal fully shaped shaft component, as the sections (15; 15', 15'') internally contain associated equipment (18) and externally feature bodies (23) for the installation of easily removable formwork elements, preferably easily mountable slipforms, while the space between the formwork elements and a prefabricated section is filled with reinforcement and concrete and the formwork elements after the hardening of poured concrete, by a per se known procedure, are moved to a higher level.</p> |
