The tower to be constructed by the method according to the invention comprises a tower shaft having a cylindrical outer surface and an element encompassing the tower shaft. On the outer surface of the tower shaft, an external thread is arranged. The element engages in the external thread so that it can be moved by turning in relation to the external thread and thus along the tower shaft. Preferably, the element engages the external thread by means of a matching internal thread to this.

An advantage of the tower to be built according to the method of the invention is that the force to be applied to a movement of the element is substantially less than the weight of the element, which would have to be applied, for example, in the case of lifting by cranes. Another advantage is that the tower is stabilized by the arranged on the outer surface of the tower shaft external thread. Furthermore, a plurality of small drives for moving the element can be provided. The cost of the drives can be kept low.

The construction of the tower shaft can be done by means of reinforced concrete and conventional methods. The ability to make the element at least largely on the ground, brings great benefits. The element can be manufactured without the usual problems of high altitude erection, which are due to wind forces and structural problems associated with the erection of formwork. This makes it possible, the element with relatively large dimensions, for example, a diameter of about 100 m, z. B. made of reinforced concrete or metal elements, such as steel beams to manufacture. Furthermore, the element can be built on the ground weather-protected in an assembly hall around the tower shaft around. It engages in a lower portion of the tower shaft arranged external thread. The element can already be fitted and interconnected on the ground, at least largely, with all mechanical and electrical components. The mechanical and electrical systems of the element can still be tested in the assembly hall for their perfect function. The element can then or already during production in relation to the external thread, for.
