Abstract: A hybrid tower section for arrangement between a concrete tower section and a steel tower section of a hybrid tower for a wind power installation. The hybrid tower section comprises a steel flange having a multiplicity of annularly arranged blind holes and having a multiplicity of annularly arranged passage holes, a steel outer casing, and a concrete core, wherein the annular arrangement of the blind holes has a larger radius than the annular arrangement of the passage holes, wherein the steel outer casing has a larger radius than the annular arrangement of the blind holes, wherein the concrete core adjoins the steel flange and the steel outer casing, and a radially inner side of the concrete core has a larger radius than the annular arrangement of the passage holes.

Abstract: A coated concrete body, more particularly an element for a tower, more particularly for a tower for a wind turbine, and also of a method for its production.

Abstract: A wind energy plant foundation is provided with a plurality of ready-made concrete foundation segments. The foundation segments have a plurality of first and second sheaths which serve to receive tension wires for bracing the foundation segments.

Abstract: A wind power plant tower segment is provided. The tower segment is designed as a jacket segment and comprises a reinforced concrete body, comprising two faces for attaching to faces of at least one further tower segment. In the region of each face, at least one connecting body is introduced in the reinforced concrete body and anchored therein for connecting to a connecting body of an adjoining tower segment. The connecting body comprises a fastening wall that is disposed substantially parallel to the respective face for absorbing a tensile load that is directed transversely to the face and transversely to the fastening wall. A wind power installation pylon having a plurality of such pylon segments, a wind power installation having a corresponding pylon, and a process for the production of a plurality of pylon segments is also provided.
