ABSTRACT:
A pre-stressed segmented concrete tower for wind power generators is described, and a method for its fabrication, wherein in a pyramidal structure is formed by prefabricated segments, the structure comprising three rounded walls formed with semi-circular segments, and three flat walls, formed with flat segments between the semi-circular walls. One standard curved mold is used for the semi-circular walls, and the flat walls are fabricated horizontally, over templates.
