Abstract
The object of the invention is a concrete segment of a section of a tower of a wind turbine and an adapter of a tower of a wind turbine and also relates to a wind turbine comprising a tower which in turn comprises the concrete segment of the section and/or the adapter.
Claims18
Concrete segment (10) of a section (50) of a tower (100) of a wind turbine, wherein the tower (100) comprises at least the concrete section (50), an adapter (20), a plurality of tensioning elements (30) configured to tension the tower and a plurality of bolts (40) configured to join the adapter (20) to the concrete section (50);
- wherein the concrete section (50) comprises:
- at least two concrete segments (10);
- at least two vertical joints (25) configured to join the at least two concrete segments (10);
- wherein the concrete segment (10) comprises:
- a height;
- an upper flange (35) which in turn comprises:
- a first set of holes (31) intended to accommodate, in use, the plurality of tensioning elements (30);
- and
- a second set of holes (32) intended accommodate, in use, the plurality of bolts (40);
- wherein the upper flange (35) comprises a circular sector (46), wherein at least a part of the second set of holes (32) is contained within the circular sector (46) and wherein the circular sector (46) comprises holes (32) that are exclusively of the second set of holes;
- and
- wherein a projection of the circular sector (46) in a vertical direction along at least part of the height of the concrete segment (10) defines a clearance gap (60) without tensioning elements (30) in a circumferential direction.
The concrete segment (10) of any of previous claims, wherein a sequence of the second set of holes (32) and the first set of holes (31) is n, 1, n, 1, n, 1, m, 1, n, 1, n, corresponding the odd positions in the sequence to the holes (32) of the second set of holes (32) and the even positions in the sequence to the holes (31) of the first set of holes
Adapter (20) of a tower (100) of a wind turbine, wherein the tower comprises the adapter (20), a concrete section (50), a plurality of tensioning elements (30) configured to tension the tower (100) and a plurality of bolts (40) configured to join the adapter (20) to the concrete section (50);
- wherein the concrete section (50) comprises:
- at least two concrete segments (10) comprising a height;
- at least two vertical joints (25) configured to join the at least two concrete segments (10);
- and
- wherein the adapter (20) comprises:
- a lower flange (45) which in turn comprises:
- a first set of holes (41) intended to accommodate, in use, the plurality of tensioning elements (30);
- and
- a second set of holes (42) intended to accommodate, in use, the plurality of bolts (40);
- wherein the lower flange (45) comprises a circular sector (36), wherein at least a part of the second set of holes (42) is contained within the circular sector (36) and wherein the circular sector (36) comprises holes (42) that are exclusively of the second set of holes;
- and
- wherein a projection, in use, of the circular sector (36) in a vertical direction along at least part of the height of the concrete segment (10) defines a clearance gap (60) without tensioning elements (30) in a circumferential direction.
(31) wherein n>=1 and m>=1.
