Abstract

A method for producing a concrete formwork for a component, in particular a tower segment for a tower, preferably a tower of a wind turbine, to a method for producing a component, in particular a tower segment for a tower, preferably a tower of a wind turbine, to a concrete formwork for a component, in particular a tower segment for a tower, preferably a tower of a wind turbine, to a component, in particular a tower segment for a tower, preferably a tower of a wind turbine, and to a pattern of a component, in particular a tower segment for a tower, preferably a tower of a wind turbine.

First claim

1 . A method comprising:
producing a concrete formwork for a component for a tower of a wind turbine, the producing comprising:
providing a pattern of the component;
erecting a production formwork around the pattern at a distance from the pattern, wherein a cavity is produced between the production formwork and the pattern and corresponds to dimensions of the concrete formwork to be produced;
filling the cavity with liquid concrete; and
hardening the concrete to the form the concrete formwork.

2 . The method as claimed in claim 1 , comprising:
removing the production formwork; and removing the pattern.

3 . The method as claimed in claim 1 , comprising:
coating surfaces of the concrete formwork facing the pattern with an anti-adhesion coating; or coating surfaces of the concrete formwork facing the pattern with a primer coating and an anti-adhesion coating.

4 . The method as claimed in claim 1 , wherein:
the dimensions of the pattern are increased in comparison with the component to be produced with the concrete formwork by a shrinkage allowance for the hardening of the concrete; or dimensions of the pattern are increased in comparison with the component to be produced with the concrete formwork by an amount that takes into account shrinkage allowances for the hardening of the concrete both of the concrete formwork and of the component to be produced with the concrete formwork.

5 . The method as claimed in claim 1 , comprising:
reinforcing the cavity with a reinforcement; and/or introducing auxiliary means for the use or transport of the concrete formwork to be produced.

6 . The method as claimed in claim 1 , wherein the concrete formwork comprises an inner portion and an outer portion that are produced simultaneously.

7 . The method as claimed in claim 1 , comprising:
separating the concrete formwork into two or more partial concrete formworks.

8 . The method as claimed in claim 1 , wherein:
the production formwork is at least one of: a concrete formwork, a fixed formwork, a timber formwork, a girder formwork, a panel formwork, a permanent formwork, a single-face formwork, a double-face formwork, a freeform formwork, or a round formwork; and the production formwork has dimensions that are suitable for road transport.

9 . A method comprising:
producing first and second concrete formworks for at least two different components for a tower of a wind turbine the producing comprising:
producing a first concrete formwork by the method as claimed in claim 1 , wherein the pattern is a first pattern;
providing a second pattern of a second component, wherein the second pattern is different from the first pattern;
erecting the production formwork, previously used for the production of the first concrete formwork, around the second pattern at a distance from the second pattern, wherein a cavity is produced between the production formwork and the second pattern and corresponds to dimensions of the second concrete formwork to be produced;
filling the cavity with liquid concrete; and
hardening the concrete to produce the second concrete formwork.

10 . A method comprising:
producing a component for a tower of a wind turbine, the producing comprising:
providing a concrete formwork produced by the method as claimed claim 1 ;
filling a cavity formed by the concrete formwork with liquid concrete; and
hardening the concrete to produce the component.

11 . The method for producing a component as claimed in claim 10 , comprising:
removing the concrete formwork; reinforcing the cavity with a reinforcement; introducing guides for tensioning wires, lines, or cables into the cavity; and finishing by at least one of: grinding or coating the component.

12 . A concrete formwork for a component for a tower of a wind turbine, wherein the concrete formwork was produced in the method as claimed in claim 1 .

13 . A component for a tower of a wind turbine wherein the component was produced by the method as claimed in claim 10 .

14 . A pattern of a component for a tower of a wind turbine, dimensions of the pattern are increased in comparison with the component to be produced with the concrete formwork by a shrinkage allowance for the concrete; and
dimensions of the pattern are increased in comparison with the component to be produced with the concrete formwork by an amount that takes into account shrinkage allowances for the concrete both of the concrete formwork and of the component to be produced with the concrete formwork.

15 . (canceled)

16 . The concrete formwork as claimed in claim 12 , wherein the component is a tower segment for the tower of the wind turbine.

17 . The method as claimed in claim 10 , wherein the component is a tower segment of a wind turbine.

18 . The method as claimed in claim 1 , wherein the component is a tower segment of a wind turbine.

19 . The method as claimed in claim 1 , wherein the concrete formwork comprises an inner portion and an outer portion that are produced one after the other.
