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: The invention relates to a wind power plant having a tower that has at least one bottom tower segment and a pre-manufactured fire protection module for fireproof receiving of a transformer. The fire protection module is placed within the bottom tower segment.

Abstract: The invention concerns a processing apparatus for processing an upper segment edge of a pylon segment of a concrete pylon for preparing the pylon segment for placement thereon of at least one further pylon segment. According to the invention it is proposed that the processing apparatus includes a processing means for processing the segment edge, and a carrier apparatus to be fixed in the region of the segment edge for displaceably carrying and guiding the processing means along the segment edge.

Abstract: The present invention concerns a lifting apparatus, in particular a cross lifting beam, for lifting a first pylon segment of a concrete pylon of a wind power installation by means of a crane, including at least one fixing means for fixing the pylon segment to the lifting apparatus, and at least one release apparatus for releasing a connection between the lifting apparatus and the pylon segment.

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.

Abstract: There is provided a process for producing precast concrete parts, in particular pylon segments. Concrete is poured into a casting mold with a planar bottom for producing a planar underside. After the concrete has reached at least a minimum strength an equalization layer is applied to a join surface of the precast concrete part that is opposite to the underside. As soon as the equalization layer has reached the minimum strength, the precast concrete part is placed on a horizontally oriented surface and the equalization layer on the top side is removed in a plane-parallel relationship with the underside.
