Tower construction

1. A tower construction for a wind turbine, comprising:

a plurality of axially disposed hollow cylindrical tower sections,

wherein each of the tower sections comprises an upper end and a lower end, and comprises a plurality of circumferentially disposed alternating first and second tower section segments defining an overlapping portion having a width and extending axially between the upper and lower end; and

wherein the width of the overlapping portions of each tower sections increases in an upward axial direction resulting in the overlapping portion at the lower end of one tower section having a width less than the overlapping portion at the upper end of an adjoined tower section.

2. The tower construction according to claim 1 , wherein the overlapping portions are fixed to each other by a connecting device.

3. The tower construction according to claim 2 , wherein the connecting device comprises bolted joints and/or welded joints.

4. The tower construction according to claim 1 , wherein the first and the second tower section segments comprise a rectangular shape respectively.

5. The tower construction according to claim 1 , wherein the first and the second tower section segments comprise same heights and different widths.

6. The tower construction according to claim 1 , wherein the first tower section segments comprise widths that are constant throughout each of the tower sections, and wherein the second tower section segments comprise widths that differ throughout each of the tower sections.

7. The tower construction according to claim 1 , wherein one of the first tower section segments is axially connected to a further one of the first tower section segments, and wherein one of the second tower section segments is axially connected to a further one of the second tower section segments.

8. The tower construction according to claim 1 , wherein at least one of the first tower section segments comprises a first connecting portion for connecting with a further one of the first tower section segments disposed at a first axial free ending, and wherein at least one of the second tower section segments comprises a second connecting portion for connecting with a further one of the second tower section segments disposed at a second axial free ending.

9. The tower construction according to claim 8 , wherein the first connecting portion is disposed at the first axial free ending of the first tower section segments, and wherein the second connecting portion is disposed at the second axial free ending of the second tower section segments.

10. The tower construction according to claim 9 , wherein the first and the second connecting portions are disposed radially outside of the first and the second tower section segments with respect to an axis of the tower construction respectively, and wherein a further first and a further second connecting portions are disposed radially inside of the first and the second tower section segments with respect to the axis of the tower construction respectively.

11. The tower construction according to claim 8 , wherein the first and the second connecting portions abut the first and the second tower section segments by bolted and/or welded joints respectively.

12. The tower construction according to claim 8 , wherein the first and the second connecting portions are pre-mounted to the first and the second tower section segments respectively.

13. The tower construction according to claim 8 , wherein the first and the second connecting portions are built as a fishplate respectively.

14. The tower construction according to claim 1 , wherein at least one of the first tower section segments and/or at least one of the second tower section segments comprises at least one at least partially axially extending bent.

15. A wind turbine, comprising:

a tower construction according to claim 1 .
