Modular tower for a wind power plant

摘要

The invention relates to a tower (1) for a wind power plant, having a lower part (1.1) in the form of a lattice tower or trussed tower having at least two corner legs, and an upper part (1.2) in the form of a tubular tower substantially round in cross-section, wherein each corner leg (1.10) is composed of a plurality of steel tube profiles (1.11, 1.12) connected to one another in the longitudinal direction. In order to achieve good transportability and simplified assembly of the components of such a tower, the invention provides a modular tower concept. According to the invention, each corner leg (1.10) is composed of at least three steel tube profiles (1.11, 1.12) which are furnished with perforated flanges (1.13) for receiving bolts, wherein the corner legs (1.10) are connected to one another by struts (1.15) and/or tie bars (1.17) connected at the flanges (1.13), and wherein the steel tube profiles (1.11, 1.12) of each corner leg (1.10) are spiral seam-welded steel tube profiles.
