Concrete Foundation, Method for Producing a Concrete Foundation for a Wind Power Tower, and Positioning Device for Positioning Jacket Pipes in a Concrete Foundation

摘要

In a method for producing a concrete foundation for a wind power tower externally preloaded and made of precast concrete parts, a formwork for the concrete foundation is erected, core elements for producing passage openings in the concrete foundation for the loading elements are positioned and fixed on the formwork, and the concrete foundation is cast. A measurement reference system is established in order to position the core elements, at least one first positioning aid having an adapter device for a core element and having at least one reference segment is provided on the formwork. A corresponding concrete foundation is produced in accordance with the described method. A positioning device for orienting core elements in a concrete foundation comprises at least one first positioning aid, which has an adapter device for a core element and at least one reference segment for calibrating the first positioning aid.
