Embodiment Construction

[0022] What has been discussed at the beginning of the text with regard to the prior art figure 1 Indicates known connections on the tower body. figure 2 and 3 represents a first embodiment of an auxiliary part according to the invention, in Figure 4 Other possible variants are shown in .

[0023] exist figure 2 and 3 The first exemplary embodiment of an auxiliary part 10 according to the invention shown in FIG. 2 is basically designed and shaped similarly to the weld-in sleeve 1 known from the prior art. The auxiliary part 10 is substantially cylindrical in design and has a preferably circular outer contour in cross section. It has uniform outer dimensions along its length, and a central bore which is internally guided in the longitudinal direction of the auxiliary part 10 . On the side of the first end side on which the auxiliary part 10 is connected to the tower wall T via a weld seam 4 or which, in the as-yet-installed state, is intended for this type of connectio...

Abstract

In order to provide an attachment element for fastening of attachment parts (P) to a metal inner tower wall (T) of a tower of a wind energy system, comprising a first end side for welding to the inner tower wall (T) and a second end side for fastening an attachment part (P), said second side opposite the first end side, wherein the resultant weld connection between said attachment element and the tower wall is under a reduced stress, thereby enabling the connection point to be assigned to a higher fatigue class, it is proposed that such an attachment part have a total cross-sectional material thickness that is reduced near the first end side in comparison to a total material thickness in a cross-section shifted toward the second end side.

Description

technical field [0001] The invention relates to an auxiliary part according to the features of the preamble of claim 1 for fastening an accessory to the inner wall of a tower of a wind energy installation. Background technique [0002] Wind power installations are all tall buildings, and their current-generating components are arranged on the upper end of a high tower in a machine room arranged there. Towers of wind energy installations are subject to high loads not only due to the high weight load of the components mounted on the machine, but also due to the load of other loads, in particular the stagnation pressure of the incoming wind. This is all the more pronounced when modern wind energy installations, as they become more powerful, are designed to be larger and thus have to be built taller. [0003] Except for one type of structure, that is, the tower body of wind energy equipment is built with a reinforced concrete frame, the tower body of wind energy equipment is of...
