Embodiment Construction

[0022] figure 1 Two mating connection parts 2, 4 of a flange connection are shown. The mating connection parts 2, 4 are oriented with abutment faces 3, 5 facing each other and are connected together by a screw connection 6 to form a positive locking connection. To compensate for surface roughness and inhomogeneities of the abutment surfaces 3, 5, a layer 10 (shown enlarged in the figure) is provided. Said layer 10 is arranged between the cooperating connection parts 2, 4 and is at least temporarily deformable. In this way, the surface structure of the mating connection part 2 , 4 at the abutment face 3 , 5 is replicated exactly in the layer 10 so that it must be accompanied by full-area contact.

[0023] Since the layer 10 contains a pressure-resistant material, the force transmission in the flange connection can now take place over the entire abutment surface 3 , 5 . In this case, a screw connection 6 is provided to form a positive locking connection between the two mating...

Abstract

The flange coupling method has a layer (10) provided between the cooperating flange surfaces (3,5) which has a viscosity which is increased during the time frame for formation of the flange coupling relative to its viscosity before and after this time frame, e.g. by passing current through electrical lines embedded in a thermoplastics layer.

Description

field of invention [0001] The invention relates to a method for connecting two flanges, in particular segments (rings) mounted to a tower of a wind power plant and flanges interconnecting said segments, wherein said flanges are force-locked relationship connected together. Background technique [0002] Such flange connections have long been known from the prior art and are widely used. Screws are often used here as connection means between the flanges, which form a positively locked connection between the mating connection parts. [0003] In this case, the quality of such a flange connection depends not only on the careful selection of materials and the perfect implementation of the installation, but also on the surfaces of the counter faces. The surfaces of the abutment faces have to be machined precisely and in a practically complex and cost-intensive manner in order to achieve a sufficiently large and planar contact surface. [0004] In this case, the outlay pertaining...
