Pre-stressed concrete tower for wind-power generator, has pyramidal structure having triangular cross section provided with rounded vertices, where structure is stacked such that tower gradually narrows and ends into circular section

摘要

The tower has a pyramidal structure with three flat walls and three rounded walls alternated and joined together to form a structure. The pyramidal structure has a triangular cross section provided with rounded vertices, where the pyramidal structure is stacked such that the tower gradually narrows and ends into a substantially circular cross section. Pres-stressing cables are provided within ducts that are embedded into circular-and flat segments, where the flat walls have ribs forming a framework. An independent claim is also included for a method for erecting a pre-stressed concrete tower for wind power generators.
