  • the objective of the present invention is to provide a wind turbine tower that solves the aforementioned problems. This is achieved with a tower with its shaft divided into a plurality of segments joined by transverse rings, at least one of said segments being formed with a plurality of precast concrete pieces, of equal height to the segment and with straight longitudinal edges, being These pieces are configured with longitudinal stiffening ribs at their edges and with at least one hole in them to form a longitudinal joint together with an identical hole in the adjacent piece, this joint being made with metallic elements and high-strength mortars arranged between them and said prefabricated parts

  • the shape of the joints 25 facilitates that they can only be made with a mortar that would be subjected to compression stresses along the diagonal and to tensile stresses in the perpendicular direction.
  • variations in the direction of the compression and traction stresses could cause the mortar to fail so that the mentioned reinforcement is advisable.
  • the discrete joints 25 according to the invention are very advantageous over the known solutions that use metal elements introduced, at least partially, in the prefabricated parts.
