Embodiment Construction

[0037] Such as figure 1 As shown, a wind turbine 1 comprises a tower 2 topped with a nacelle 3 and a rotor 4 comprising a plurality of blades 5 .

[0038] The tower 2 comprises a plurality of blocks 6 stacked on top of each other, thereby giving the tower 2 a generally elongated shape.

[0039] In the rest of the description, the tower 2 is considered to extend in a vertical direction.

[0040] The tower 2 is rigidly fixed to the foundation or foundation plate 7 .

[0041] The height of block 6 is preferably identical.

[0042] Each block 6 is constructed using a material such as reinforced concrete.

[0043] Such as figure 1 It can be seen that each block 6 of the upper part 2a is generally cylindrical, while each block 6 of the lower part 2b is generally conical.

[0044] Of course, the invention is not only applicable to the tower 2 shown, but may also be applicable to other tower forms, such as towers consisting only of cylindrical blocks or towers consisting only of ...

Abstract

The present invention relates to a method of manufacturing concrete structural blocks (6) for a wind turbine tower comprising at least two continuous blocks through the contact surface of each of the two blocks fixed to each other, the manufacturing method comprising the steps of: pouring concrete into a first reinforcement cage (10-1), thereby obtaining a first concrete structural block comprising an upper contact surface (9b); and pouring concrete into a second reinforcement cage In (10-2), the second concrete structural block is obtained, the second reinforcing cage is arranged in the formwork (21), and the formwork (21) is set so that the upper contact surface ( 9b) Forming a wall (26) delimiting the poured concrete so as to form the lower contact surface (9a) of the second block (6-2).

Description

technical field [0001] The invention relates to a method of manufacturing a concrete structural block for a wind turbine tower made of at least two continuous blocks. Background technique [0002] Typically, such a tower is topped with a nacelle and a rotor consisting of a plurality of blades in order to form a wind generator. [0003] Two consecutive blocks are stacked on top of each other by the contact surface of each of the two blocks. [0004] It is known to manufacture each block by assembling a plurality of panels at the installation site of the wind turbine or pouring concrete into a mould, for example a cylindrical mould. In this case, once the concrete has set, removal from the mold makes it possible to directly obtain the concrete structural block in one-piece form. [0005] Two consecutive blocks are secured by a concreted joint, or mortar or grout, depending on the thickness of the joint on the contact surface of each block. [0006] Due to imperfections or g...
