Wind turbine tower and method for constructing a wind turbine tower
First Claim
Patent Images
1. A wind turbine tower configured to support a rotor assembly having a hub and at least one blade, comprising:
- a plurality of wind-turbine-tower segments form the wind turbine tower, each wind-turbine-tower segment having a polygonal cross section, each wind-turbine-tower segment comprises;
a plurality of flat plates connected to each other to form the polygonal cross section, each flat plate having a first side and a second side facing away from the first side; and
a plurality of splice plates, which are bent, connect the plurality of flat plates to each other, each of the plurality of splice plates abut to the first side of two of the plurality of flat plates that are arranged adjacently such that the plurality of splice plates are arranged on an inside of the polygon cross section; and
an external surface of the wind turbine tower formed from the second side of the plurality of flat plates;
wherein the flat plates substantially enclose the splice plates.

Abstract
A wind turbine tower is provided, which comprises a number of segments with a polygonal cross section, each segment comprising a number of flat plates which are connected to each other so as to form the polygonal cross section. Further, a method for constructing a wind turbine tower which comprises segments assembled of flat plates is disclosed, wherein the flat plates are connected to each other so as to form segments with a polygonal cross section and the segments are connected to each other so as to form the tower.

12. A method for constructing a wind turbine tower configured to support a rotor assembly having a hub and at least one blade, comprising:
-
providing a plurality of flat plates having a first side and a second side facing away from the first side; connecting the flat plates to each other via a plurality of bent splice plates to form wind-turbine-tower segments each having a polygonal cross section, each bent splice plate abuts to the first side of two of the plurality of flat plates which are arranged adjacently to form the interior of the wind-turbine-tower segments; and connecting the wind-turbine-tower segments to one another to form the wind turbine tower such that an external surface of the wind turbine tower formed from the second side of the plurality of flat plates; wherein the flat plates substantially enclose the splice plates. - View Dependent Claims (13, 14, 15, 16)
