Embodiment Construction

[0028] attached Figures 1 to 4 A first embodiment of a connection or fitting 10 according to the invention is shown in .

[0029] The connection or connecting element 10 shown is referred to below only as a connecting element, which is especially suitable for the steel structure of a tower, preferably for a wind power plant, and which is produced in particular by the method according to the invention.

[0030] The connecting piece 10 has a flange 12 and a housing 14, wherein the housing 14 is connected in one piece to the flange 12 and wherein the end of the housing 14 opposite the flange 12 is adapted to a steel structure, in particular having a round or polygonal shape. The profile of the part of the cross-sectional tubular corner bracket 30 which is to be connected to the housing 14 .

[0031] Here, the housing 14 has a conical shape with a section 16 which is likewise conical, but extends at a more gradual angle. The flange 12 is here connected to the tapering end of th...

Abstract

The invention relates to a method for producing a connection element, in particular for steel structures of towers, preferably for wind turbines and to a connection element or node element, wherein a flange (12) and a shell (14) integrally adjoining the flange (12) is produced from a blank (40) by means of a flow forming process, and then the end of the shell (14) opposite the flange (12) is adapted to the contour of the component to which the shell (14) is to be connected. The invention further relates to a connection and node element.

Description

technical field [0001] The invention relates to a method for producing a connection or joint of a steel structure, in particular a tower, preferably a wind power plant, and a connection or joint. Background technique [0002] On masts and towers, especially on wind power plants or voltage masts, the struts are usually connected at different heights and at different angles to substantially upright standing mast structures such as corner brackets. [0003] For this purpose, it is known in the prior art to form welded structures consisting of individual sheet metals as connecting parts. In particular, weld seams produce metallurgical gaps and thus low fatigue strength. In addition, this construction leads to an accumulation of many individual components and thus weld seams in areas of fatigue stress, as well as high installation and logistical outlay. Such a construction is known in principle from EP2270294A2. [0004] In addition, it is also known to produce the connecting ...
