- the wind turbine tower typically comprises a number of round tower rings mounted on top of each other, where each tower ring is made of a steel plate rolled into a circular shape and welded to constitute a closed ring.
- the object of the present invention is to provide technique which allows higher strength of the flange joint connections to be established with the same or less flange material to be used.
- connecting means comprises at least one nut with at least one assembly opening for interacting with an assembly tool.
- the length and thickness of the flanges may also be decreased as a result of the higher strength connection i.e. less flange material is used.
- flanges with the same amount of flange material may be used but with flange material of a lower strength and thus a lower cost price.
- assembly tool should be understood as a tool which may be used in an assembling or disassembling operation in connection with the invention.
- said nut with a bolt form a set of connection means.
- bolt should be understood as a headed fastener having an external thread that may meet an exacting, uniform bolt thread specification such that it can accept a nontapered nut.
- the lower part of the nut comprises an opening with an internal thread corresponding to the thread and length of the bolt in the set.
- said nut comprises one assembly opening for interacting with an assembly tool.

- connection means such as a bolt and a corresponding nut
- a normal procedure may involve the nut being tightened and the bolt being held in place as the opposite procedure may result in an overturning of the bolt head.
- the length Lb of the shaft of said bolt is prechosen to correspond substantially to the sum of the size T f of said flanged joint and the length L n2 of the internal thread part of said nut.
- connection means wherein the nut further comprises at least one assembly opening for interacting with an assembly tool.
- the invention relates to a method for assembling a wind turbine tower where a fixating is initiated by an assembly tool tightening a set of connection means by entering at least one assembly opening in a nut of said set of connection means.
- a fixating is initiated by an assembly tool tightening a set of connection means by entering at least one assembly opening in a nut of said set of connection means.
- the invention relates to a method for manufacturing a nut of the connection means for fixating wind turbine tower including at least two tower sections, said method comprising the steps of, establishing a through going hole in said nut, establishing an assembly opening in the nut, and establishing an internal thread in the lower part of the hole whereby the size of the internal thread is larger than the size of the assembly opening.

- the different components of a wind turbine are usually transported separately to the site of mounting and assembled there e.g. the different tower sections, the nacelle and the wind turbine blades.
- Fig. 2 illustrates a part of a flanged joint in between two wind turbine tower sections according to the invention.
- the tower flange usually establishes a full circle with the tower section but may also be divided into a number of flange sections which together form a full circle corresponding to the tower section.
- the figure especially illustrates a part of an upper tower section 2 which at its lower edge is connected to a first flange 8a in a welding seam 14.
- the flange 8a has a first and second arm wherein the arms together form a substantially perpendicular angle.

- the inner surface of the socket part may interact with the head of the assembly tool and thus allow the nut to be tightened from above instead of from the side.
- the threaded part 12 of the nut 9 has a depth L n2 that extends from a top surface of the nut and in to the beginning of the socket part of the nut.
- the depth L n2 at least corresponds to length of the bolt rod 10b extending out of the flange hole 18.
- L nl and L n2 may be chosen freely but is preferably similar in size.
- the bolt rod 10b including a threaded part 10c has a length L b that allows the bolt to extend the necessary distance out of the flange hole 18 in order to establish a threaded connection with the nut 9.
