Title:
CONCRETE FOUNDATION, METHOD FOR PRODUCING A CONCRETE FOUNDATION FOR A WIND POWER TOWER, AND POSITIONING DEVICE FOR POSITIONING JACKET PIPES IN A CONCRETE FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2014/191102
Kind Code:
A3
Abstract:
The invention relates to a method for producing a concrete foundation (1) for a wind power tower (3) that is preloaded by means of loading elements (2), in particular an externally preloaded wind power tower (3) made of precast concrete parts (4), wherein a formwork (7) for the concrete foundation (1) is erected, wherein core elements (12) for producing passage openings in the concrete foundation (1) for the loading elements (2) are positioned and fixed on the formwork (7), and wherein thereafter the concrete foundation (1) is cast. According to the invention a measurement reference system is established in order to position the core elements (12), at least one first positioning aid (13) having an adapter device (16) for a core element (12) and having at least one reference segment (17) is provided on the formwork (7), the first positioning aid (13) is calibrated in a positionally accurate manner by means of the reference segment (17) on the basis of specified target coordinates in the measurement reference system and fixed in the formwork (7), and the particular core element (12) to be positioned is then arranged on the adapter device (16) of the positioning aid (13) and thereby the core element (12) is positioned in an intended fastening position (28) in a positionally accurate manner at least by means of the lower end of the core element. A corresponding concrete foundation (1) is produced in accordance with the described method. A positioning device for orienting core elements (12) in a concrete foundation (1) comprises at least one first positioning aid (13), which has an adapter device (16) for a core element (12) and at least one reference segment (17) for calibrating the first positioning aid (13).
