<p>The invention aims at ensuring the form and stability of cylindrical or straight prismatic towers during the sliding operation. To this end, the reinforcement structures for the final state such as the horizontal spoked wheels are temporarily integrated into the sliding mold and simultaneously used for other provisional structures. In the case of very high towers, for instance chimneys for upwind power stations, cooling towers and silos requiring several reinforcements, the top reinforcement for stabilizing the free crown is integrated into the sliding mold and used as a base for the lifting device of the lower reinforcements. The latter are lifted as a packet, the lowermost reinforcement being left at a predetermined height and connected to the reinforced concrete shell. The reinforcement fixed to the sliding mold protects the geometrical form and provides the required rigidity to the finished reinforced concrete shell, for instance, in case of load due to wind pressure. It can be used as contact surface for the upper stations of the cable-guided elevators and for the supporting structure of the horizontal bucket transport system as well as for the distribution of material on the perimetry.</p> |
