Abstract (en)
[origin: WO2017045907A2] The invention relates to a tower (1) for a wind turbine, having at least one tower portion (3) which is made of concrete and assembled from multiple superposed annular concrete segments (7) such that horizontal joints (6) are formed, wherein every concrete segment (7) is assembled from at least two juxtaposed prefabricated concrete parts (9) in the shape of annular segments such that vertical joints (8) are formed, the prefabricated concreted parts each having an outer side (10), an inner side (16) and one upper, one lower and two lateral contact faces (11, 12, 13). In the vertical direction of the tower (1) the concrete segments (7) of the at least one tower portion (3) are interconnected only by vertical clamping means. The vertical joints (8) of two superposed concrete segments (7) are always arranged offset relative to each in the circumferential direction of the concrete segments (7), with one prefabricated concrete part (9) of an upper concrete segments (7) of the two superposed concrete segments (7) overlapping a vertical joint (8) of a concrete segment (7) situated beneath the upper of the two superposed concrete segments (7). The superposed concrete segments (7) are clamped together by the vertical clamping means, in particular vertical clamping members (18), in such a way that a load-distributing frictional connection is produced.
