Abstract
An annular preform is constructed of predeterminable width and height and filled with a predeterminable quantity of a fluid grouting material. After setting of the grouting material and removal of the formwork a ring is placed on the surface of the set grouting material and a lower pylon segment is placed on the ring and connected thereto.
Claims10
A method of erecting a pylon of a wind power installation, comprising:
- forming a foundation with segment anchors, wherein continuous connecting elements are coupled to the segment anchors and project beyond a top side of the foundation by a predetermined amount;
- constructing an annular formwork of predeterminable width and height on the top side of the foundation;
- filling the formwork with a predeterminable amount of a fluid grouting material that levels itself;
- allowing the grouting material to set such that a leveled surface is automatically available;
- removing the formwork;
- placing a ring, having a plurality of first holes for receiving the connecting elements which project beyond the top side of the foundation, on the leveled surface of the grouting material which has set;
- and
- connecting a lower pylon segment, having a plurality of second holes for receiving the connecting elements, on the ring via the connecting elements.

A wind power installation, comprising:
- a pylon which has at least a lower pylon segment, the lower pylon segment including a lower flange ring having a plurality of holes;
- a foundation with embedded segment anchors;
- a ring of grouting material made from a fluid grouting material which has set, the ring of grouting material positioned on a top side of the foundation;
- continuous connecting elements which are coupled to the segment anchors and project a predetermined distance above the top side of the foundation;
- and
- a leveling ring which has a plurality of holes for receiving the connecting elements and is arranged on the ring of grouting material which has set, and wherein the lower pylon segment is positioned on the leveling ring such that the lower flange ring receives the connecting elements through the plurality of holes of the lower flange ring.
