Abstract

The invention comprises a series of spans of column shaft (1) with a frustoconical shape, each span integrating two or more parts (2) and (3) with a polygonal or circular section formed with pieces prestressed in a bed in the factory, with centered or slightly deviated prestressing (4) and non-prestressed reinforcement (5) in the perimeter of the section or fibers, attached by means of wet or dry longitudinal joints (6), rotated in plan view or not, and transverse joints (7) which can be at different levels and provide continuity or not to the general prestressing, for a joining by means of steel bars (12), and in the case of the attachment to the foundation with direct positioning of the starter bars at the time said foundation is built, or by means of jacket tubes which will subsequently receive the mentioned bars (16).

Description

[0001] The present invention relates to a vertical support structure or tower for wind turbines generating electric energy or other uses, made of prestressed concrete, providing a frustoconical or cylindrical column shaft of prestressed concrete with variable height built by means of annular sectors, each of which comprises several wall pieces with a semicircular or polygonal section or semicircular or polygonal sectors, longitudinally attached to each other, and in the case of several superimposed in height, longitudinally attached with a system allowing the structural continuity of the tower. Either the wind turbine directly or another metal column shaft on which the turbine will finally be fixed will be located at its upper end.

[0002] This invention also has its application in the field of construction in general and especially in the industry for building and installing support structures for wind turbines generating electric energy.

[0003] A second aspect of the invention relates t...
