  • the present invention belongs to the field of towers for wind generators, in particular, it refers to a hybrid tower of concrete and steel, and more particularly it refers to a transition flange for a hybrid tower of concrete and steel.
  • Hybrid towers for supporting wind generators are known in the art. These towers have a foundation on which lies a first section or lower section made of concrete, (hereinafter concrete section), which can be post-tensioned concrete and a second section or upper section made of steel, (hereinafter section of steel), and on which the wind generator is arranged.
  • Hybrid towers have the advantage that they absorb the vibration generated in the wind generator.
  • the flanges of said towers consist of a metal part that is anchored -with bolts or anchors-, on the upper end of the concrete section.
  • Such embodiments have the disadvantage that the concrete tends to shear when subjected to tensile loads, such that the force exerted by the wind generator in use gradually weakens the concrete in the area of the flange.
  • Japanese utility model No. JP-U3074144 describes a hybrid tower where the steel section has an external diameter identical to that of the concrete section.
  • the steel section has a base that is also frictionally attached to the concrete section, by means of the pressure exerted by the pre-stress means on the base.
  • Said embodiment has the disadvantage that the contact surface of the base and the upper end of the concrete section is not flat and therefore gives rise to gaps that widen when the nacelle comes into use, in addition, because the section Steel has the same diameter as the concrete section, the cost of the metal section is higher compared to systems where the metal section has a smaller diameter than the concrete section.
  • To maintain the tower section it is necessary to disassemble the pre-stress tendons, with the risk involved in the concrete structure.
  • 2013081350A1 describes a flange for connecting the portions of concrete and metal where the flange includes elongated anchors to reduce damage to the concrete portion. Said flange also has a metal surface that is disposed on the surface of the concrete section by means of casting the concrete onto the flange. Although the union of the flange with the concrete is effective, the bolts that join the steel section remain anchored as in the prior art to the concrete section, which, as stated, subjects the concrete section to loads of traction that crumble the concrete and damage the concrete structure. Therefore, it is required to provide a flange that prevents the tensile loads of the steel section or of the nacelle or wind generated being transmitted directly to the concrete section.
  • a first object of the invention is to provide a transition flange for the connection of the steel portion with the concrete portion of a hybrid tower for wind generators, which provides adequate stability to the structure's transition.
  • Another objective is to provide a suitable flange for maintenance that allows decoupling of the metal section without affecting the integrity of the concrete section of the hybrid tower.
  • Another object of the invention is to provide, a flange that fits properly on the face of the smooth upper surface of the concrete section, to provide a narrow assembly between said surfaces, such that the forces intervening between said surfaces act uniquely over the entire portion of concrete and steel.
  • Another object of the invention is to provide a flange that fits over the lower smooth face of the steel section, specifically with the upper face of the base ring, this achieves a narrow adjustment of the metal section with the flange, such that the forces that intervene between these surfaces act uniquely on the entire steel portion and the flange, the use of the transition flange in the hybrid tower gives great stability to the structure and rigidity, especially when there are external events that influence the tower.
  • Still another objective is the assembly of said flange with a nacelle, in such a way that a nacelle support, performs the same function as a portion of steel, only that said nacelle support helps hold the parts of the wind turbine and thus have a flange to make the assembly of a wind turbine in the tower.
