Steel tube tower of a wind turbine, as well as methods for manufacturing and assembling the tower components

摘要

Prestressed conical or cylindrical polygonal tubular steel tower 1 of a wind turbine with a preferably welded tower head section 2.1, non-welded sections 2.2 to 2.n and a corner distance in radians corresponding to the opening angle α of the door opening 3 including the door opening reinforcement 3.1 made of high-strength steel with a yield strength of 460 MPa 1100 MPa and telescopically nested longitudinally subdivided sections 2.n characterized in that the sections, the intervening connectors and the plug interface 4.1 to 4.n to the foundation 5 via tensioning cables 6.1.1 to 6.nm inside the tower in the axial direction as far as pressure are biased that even at maximum tower deflection no divergence of the connectors 4.1 to 4.n can occur and that the required Axialdruckfestigkeit and dent resistance of the sections 2.1 to 2.n arranged longitudinally to the tower axis, in Walzri stiffened single-shell tower components 2.1.1 to 2.nm of ultra-high strength sheet metal with seamlessly integrated radially inwardly directed longitudinal ribs Rn.m and / or double or multi-shell high-strength steel profiles and / or corresponding high-strength profile composite steel-plastic or steel-concrete is achieved and that the tower components 2.nm of the non-welded sections 2.2 to 2.n are connected at the longitudinal sides via clamping connections 7.2.1 to 7.nm.
