Abstract

A method for the production of a tower of a wind power plant is disclosed wherein at least one tubular tower section is produced from annular precast concrete parts having two horizontal contact surfaces, which are arranged on top of one another. After casting, the annular precast concrete parts are set up in a processing station in the precast plant and the two horizontal contact surfaces of the precast concrete parts are processed in an orientation setting in a plane-parallel, material-removing manner. A tower of a wind power plant comprises at least one tubular tower section of annular precast concrete parts having two horizontal contact surfaces, which are arranged on top of one another. Both horizontal contact surfaces of the precast concrete parts are reworked in a plane-parallel, material-removing manner with a small parallelism deviation and a small flatness deviation.

Dependent claims

A method for building a tower for a wind power plant, the method comprising:

providing annular prefabricated concrete parts comprising poured concrete for making at least one tubular tower section formed by placing the annular prefabricated concrete parts on too of one another, each annular prefabricated concrete part comprising two horizontal contact surfaces, each of the two horizontal contact surfaces of the respective annular prefabricated concrete parts forming a joint with another horizontal contact surface of another prefabricated concrete part;
clamping each of said annular prefabricated concrete parts in a single orientation setting in an installation position on a revolving table in a processing station of a prefabricated parts factory;
processing each of said annular prefabricated concrete parts to remove material from both of the two horizontal contact surfaces of each of said prefabricated concrete parts by rotating the annular prefabricated concrete parts on the revolving table around a vertical axis while the annular prefabricated concrete parts are in the same single orientation setting so that the two horizontal contact surfaces of each of said annular prefabricated concrete parts are plane-parallel without application of a leveling layer;
and
placing the annular prefabricated concrete parts on top of one another to form said at least one tubular tower section.
