摘要

A support structure for wind turbines comprising a column shaft (1) formed by superimposed annular structural sections attached to each other by transverse joints (7), with a polygonal or circular fraction cross - section, each annular structural section comprising several of said adjacent wall pieces attached by longitudinal joints, wherein each of the wall pieces is obtained by prestressing in the factory and each of said wall pieces is assembled with the adjacent ones in superimposition to form the support structure, with an attachment only at their opposing abutting ends and without an additional post- tensioning affecting the entire pieces.
