Abstract

A transition body may be disposed between upper and lower tower sections of a tower for a wind power station. Some example transition bodies may include a substantially annular upper connection flange for connection to the upper tower section, and at least three substantially annular lower connection flanges, each of which may connect to a corner leg of the lower tower section. The transition body may have several segments disposed about a central tower axis, with the number of segments corresponding to the number of corner legs. Upper peripheral sections of the segments may form an annular circumferential connection envelope that supports the upper connection flange. Lower sections of the segments may form annular circumferential segment envelopes that support the lower connection flanges. The segments may be disposed at acute angles and converge into one another at or near the upper connection flange.
