  • the invention relates to a screw seam tube made of a helically bent sheet metal, which is welded to a screw seam line.
  • the invention further relates to a method for producing a screw seam tube and the use of a screw seam tube for producing a tower structure.
  • Tower structures of wind power generators usually consist of several segments, which are composed of several pipe sections. The pipe sections are usually screwed together on flange connections.
  • the individual segments or pipe sections are manufactured in one plant and assembled on site to form a tower structure.
  • the wall thickness of the individual pipe sections is designed according to the expected loads. This means that, for example, the segments or pipe sections in the area of the tower base have a correspondingly large diameter and a large wall thickness, while the segments or pipe sections to be arranged further up have a smaller diameter and also a smaller wall thickness.
  • the size of the segments to be used is often limited by the required transportation to the construction site. It is also often desirable to optimize the wall thickness and geometry of individual segments with regard to the expected bending stress. It is known in the prior art to build structures for accommodating wind power generators from conical, spirally welded segments put together. No.
  • 8,720,153 B2 discloses a method for producing a tapered conical structure from spirally welded metal sheets, the basic shape of the cone being obtained by first cutting the shape of the cone graphically axially and unwinding it into the plane. The edge lines of one or more strips are then drawn on the trapezoid thus obtained. Correspondingly cut sheets are then wound into a conical structure with a helical seam line and welded together along the resulting seam line. This process is complex and complicated.
  • US 2018/0193893 A1 discloses a method for producing a cylindrical screw seam tube with a wall thickness that varies over its length.
  • a plurality of sheets of different wall thicknesses are welded to form a strip or a band, which is bent in a helical manner into a slot tube by means of a bending device and which is welded along a continuous screw seam line.
  • the process requires the provision of a large number of sheets with different wall thicknesses.
  • a screw seam tube produced in this way comprises a plurality of transverse weld seams which form lines of weakness or notch lines of the tube. Due to the fact that as a rule a different wall thickness is used for each cycle, there are also material leaps that must be taken into account when calculating the resulting structure.
  • the invention is therefore based on the object of avoiding the disadvantages mentioned above, in particular of providing a screw seam tube which can be produced in a relatively simple manner with a wall thickness distribution which is adapted to the expected load.
  • the invention is also based on the object of providing a method for producing such a screw seam tube.
  • the invention is based on the object of making it possible to manufacture a structure using screw seam tubes which is structurally adapted in a simple manner to the bending line to be expected.
  • a screw seam tube which comprises at least one cylindrical tube section, which consists of a one-piece, helically curved metal band which is welded to a screw seam line and has a wall thickness which varies over its length.
  • So-called coil strips obtained by hot rolling in a rolling mill can preferably be used as metal strips.
  • Such metal strips can be provided relatively easily with a diameter varying over their length or with a wall thickness varying over their length.
  • the screw seam tube according to the invention is preferably composed of a multiplicity of cylindrical tube sections which are in each case joined together at the ends.
  • the individual pipe sections can be welded together, for example.
