Abstract

A wall portion for a tower of a wind turbine is provided. The wall portion has a first wall segment having a first flange at a lateral side of the first wall segment; a connection plate having a surface portion being mounted at a front side surface portion of the first wall segment; a second wall segment having a second flange at a lateral side of the second wall segment; and a third wall segment. The second flange is mechanically connected to the first flange. The connection plate protrudes an edge at another lateral side of the first wall segment. Another surface portion of the connection plate is mounted at a front side surface portion of the third wall segment and the connection plate protrudes an edge at a lateral side of the third wall segment.

Claims

1-15. -15. (canceled)

16. A wall portion for a tower of a wind turbine, comprising:

a first wall segment comprising a first flange at a first lateral side of the first wall segment;

a connection plate comprising a first surface portion being mounted at a front side surface portion of the first wall segment, the connection plate protruding an edge at a second lateral side of the first wall segment;

a second wall segment comprising a second flange at a first lateral side of the second wall segment, wherein the second flange is mechanically connected to the first flange; and

a third wall segment, wherein a second surface portion of the connection plate is mounted at a front side surface portion of the third wall segment, the connection plate protruding an edge at a lateral side of the third wall segment,

wherein the first flange and the second flange extend in a longitudinal direction of the tower of the wind turbine.

17. The wall portion according to claim 16, wherein the first wall segment and the second wall segment are laterally spaced apart from each other in a first direction.

18. The wall portion according to claim 16, wherein the first wall segment and the third wall segment are laterally spaced apart from each other in a second direction different from the first direction.

19. The wall portion according to claim 16, wherein the edge of the first wall segment is adjacent to the edge of the third wall segment.

20. The wall portion according to claim 16, wherein the first surface portion of the connection plate and the second surface portion of the connection plate are arranged on a same side of the connection plate.

21. The wall portion according to claim 16, wherein the first surface portion of the connection plate is in contact with the front side surface portion of the first wall segment.

22. The wall portion according to claim 16, wherein a friction increasing material is arranged between the first surface portion of the connection plate and the front side surface portion of the first wall segment.

23. The wall portion according to claim 16, wherein a thickness of the connection plate is greater than a thickness of at least one of the first wall segment and the third wall segment.

24. The wall portion according to claim 16, further comprising:

a further connection plate comprising a first surface portion being mounted at a back side surface portion of the first wall segment,

wherein the back side surface portion of the first wall segment is opposite to the front side portion of the first wall segment,

wherein a second surface portion of the further connection plate is mounted at a back side surface portion of the third wall segment, and

wherein the back side surface portion of the third wall segment is opposite to the front side portion of the third wall segment.

25. The wall portion according to claim 24, wherein a thickness of at least one of the connection plate and the further connection plate equals to at least half of a thickness of at least one of the first wall segment and the third wall segment.

26. The wall portion according to claim 24, wherein the connection plate and/or the further connection plate is mounted using a bolt and/or a nut.

27. The wall portion according to claim 16, wherein the first wall segment, the second wall segment and/or the third wall segment comprises steel.

28. The wall portion according to claim 16, wherein the first flange of the first wall segment is integrally formed with the first wall segment.

29. The wall portion according to claim 28, wherein the first flange of the first wall segment is integrally formed with the first wall segment by bending.

30. The wall portion according to claim 16, wherein the first flange of the first wall segment is a component separate from the first wall segment and connected to the first wall segment.

31. A wind turbine tower wall, comprising:

a wind turbine tower wall portion according to claim 16,

wherein the first flange of the first wall segment protrudes into an inside of a tower of the wind turbine tower wall.
