Definitions

  • the present invention relates to a dissolved structural structure, in particular a lattice tower structure, for a wind energy plant according to the preamble of claim 1.
  • the invention relates to a foundation structure which is designed as a dissolved structural structure, in particular as a lattice tower structure, and e.g. is anchored as an offshore foundation structure by means of rammed foundation piles, in particular by means of pre-drilled hollow piles, to the ground.
  • the present invention relates to a method for producing a dissolved structural structure, in particular a lattice tower structure, according to the preamble of claim 13.
  • lattice tower structures As resolved structural structures, for example, tripods, tripiles or lattice tower structures are called. In the following, the invention is explained using the example of such lattice tower structures, without this being to be understood as a restriction.
  • Straight lattice tower structures are well known in wind turbines, eg as lattice towers for wind turbines as an alternative to tubular steel towers.
  • lattice tower structures known as foundation structures over which the connection of a building with the ground.
  • Such known foundation structures consist for example of a lattice structure of corner posts and trusses arranged between the corner posts struts. In other dissolved structural structures one does not speak of corner stems, but of legs.
  • mortar Grout
  • the corner stalk is extended at its free end with so-called jacket legs.
  • These jacket legs are mounted so that they stand in the vertical direction in the foundation piles, while the corner stems have a tilt to the vertical direction.
  • These jacket legs are according to the diction of the present application part of the corner stem and thus covered by the term "corner stem".
  • the joining of the corner stems with the piles can therefore also be the joining of the jacket legs with the piles.
  • Known foundation structures are commonly referred to as jacket foundations and used predominantly in the offshore area, that is, the foundation structure is in the sea and the hollow piles are anchored in the seabed.
  • a tower construction in particular a wind turbine can be arranged, for example, a wind turbine with a lattice or a steel tube tower.
  • the aforementioned lattice tower structures consist of so-called primary and secondary structures.
  • the primary structures are those parts of the lattice tower structure that remove the loads from the wind turbine. These loads include static, eg resulting from the weight of the wind turbine, and also dynamic loads, for example, resulting from the rotor rotation and changing winds.
  • the primary structures include, for example, the corner stems and the struts connecting the corner stems and extending between the corner stems. These include nodes, eg cast and weld nodes.
  • the secondary structures do not have a load-bearing function which is relevant to stability, but are intended to fulfill functional tasks and the associated tasks Loads (eg impact loads from service vessels to jetty) into the primary structure.
  • Secondary structures are, for example, cable guide tubes (J-tubes), platforms and feeders for landing boats, work platforms, or pile stoppers on the anchoring-side end portions of the corner stems which control the depth of penetration of a corner stalk when inserted into a seabed limit the drilled hollow pile.
  • J-tubes cable guide tubes
  • platforms and feeders for landing boats work platforms
  • pile stoppers on the anchoring-side end portions of the corner stems which control the depth of penetration of a corner stalk when inserted into a seabed limit the drilled hollow pile.
  • the secondary structures via material connection, in which the material of the structures is metallurgically changed, as z. B. when welding is the case, connected to the primary structures.
  • the primary structures For example, Platforms are welded to the corner posts or braces.
  • the disadvantage of welded joints is that the metallurgical change of the structure produces a notch effect which reduces the fatigue strength of the structure.
  • the primary structure must be made larger in order to compensate for the reduction in fatigue strength, thereby increasing the cost of the lattice tower structure.
  • the object of the present invention is to provide an improved lattice tower structure or dissolved structural structure in this respect.
  • the lattice tower structure according to the invention or dissolved structural structure is characterized in that the cohesive connection between the primary and the secondary structure is designed as a bonding connecting layer arranged between primary and secondary structure.
  • connection is made via a bonding layer.
  • the bonding layer has the advantage that no metallurgical changes in the material structure are generated and thus no notch effect occurs. Accordingly, the fatigue strength of the load-bearing primary structures in particular is not impaired. This has the consequence advantageously that the primary structures and also the secondary structures over the prior art at least partially lighter dimensions and costs can be saved accordingly.
  • connection layer may be an adhesive layer.
  • Adhesive connections are basically already known in steel construction. Suitable adhesive bonds and adhesives are described inter alia in the article " Gluing in steel construction "in the journal Stahlbau 75 (2006), Issue 10, pages 834 ff., Authors: Markus Feldmann et al. described.
  • An alternative bonding agent to adhesive may be (normal or high strength) grout according to another aspect of the invention.
  • mortar compounds also called Grout compounds
  • Grout compounds are basically known from the prior art, so that no further explanation is required.
  • the primary and secondary structures could be directly bonded to one another with a material fit, the adhesive or coarse layer would then be arranged directly between the two attachment partners.
  • An advantageous embodiment of the invention provides, however, that the secondary structure is attached to a sleeve, in particular by welding, and that the sleeve rests positively on the primary structure, wherein the connection layer is formed between the sleeve and the primary structure.
  • This embodiment according to the invention offers the advantage that the secondary structure does not have to be fastened directly to the primary structure, which is e.g. then a problem can be if only small interfaces are available.
  • the cuff may have a bonding surface of suitable size and contour, and the secondary structure may be e.g. welded to the cuff. But cuff and secondary structure can also be connected in other ways or be made in one piece.
  • a cuff has the advantage that it can be produced in a variety of sizes and shapes, and that the loads occurring through the secondary structure are removed via the cuff and via the bonding layer to the primary structure, without structurally weakening the primary structure.
  • the sleeve can be formed according to a further embodiment, at least two parts.
  • This embodiment offers the advantage that the collar can be arranged in a simple manner on the primary structure.
  • the sleeve may e.g. consist of two 180 ° shells that complement each other, possibly together with auxiliary shells, to form a closed ring.
  • the dishes may e.g. be joined by welding or screwing.
  • the invention can be implemented if the dissolved structural structure or the lattice tower structure is a foundation structure, the primary structure a corner stem or a leg, and the secondary structure a support for the depth limitation of the corner stem or leg when inserted into pre-excavated hollow piles is.
  • These supports are also referred to as pile stoppers.
  • the fastening according to the invention by means of a connecting layer with respect to the welding can be implemented more advantageously and without problems in terms of construction.
  • the pile stopper is welded to the Eckstiel well before the establishment of the foundation structure, namely on land in a workshop.
  • the embodiment of the invention has the advantage that the connection between the corner post and the pile stopper after the measurement of the pre-piles can be made either directly on site or just before loading on land, so that the arrangement of the pile stopper at the corner handle can be adapted to the actual pile height on site. This is possible because both an adhesive and a mortar compound in a relatively short time and in consistently good quality can be produced.
  • a requirement for offshore wind turbines is that they must have sufficient earthing. This resulted in the prior art that when using height compensation plates, especially those with elastic properties, no electrical contact between corner post and foundation pile was that would otherwise have been produced by the resting on the pile pile stopper, so that subsequently a electrical connection had to be made, for example, by subsequent attachment of a conductor between pile stopper and foundation pile. This work had to be done by divers.
  • the subsequent arrangement of such an electrical conductor is no longer necessary in the embodiment according to the invention, since the pile stopper advantageously rests directly on the pile, whereby an electrical line is produced.
  • the embodiment according to the invention has the advantage that no notch effect occurs due to the connection type according to the invention. Accordingly, the pile stopper would not have to be removed, because a partial load transfer is unproblematic here. If there would be a failure of the compound according to the invention after the establishment of the foundation, this would even be the case, since then there is a load transfer to 100% via the Grout connection.
  • the pile stopper of a bottom-side Auflagerringplatte with central through hole for the corner handle or the leg arranged from a ring inside the Auflagerringplatte, surrounding the through hole, cylindrical extension piece and constructed of a plurality of reinforcing fins, which are arranged along the circumference of standing substantially perpendicular to the Auflagerringplattenebene extension radially outwards, in particular delta form, between Auflagerringplatte and extension piece, the Auflagerringplatte the pole sized in a foundation pile inserted Eckstiel or leg radially outstanding is.
  • This structure is characterized as material-saving and yet stable.
  • the pile stopper is formed at least two parts, since a split pile stopper is easier to mount on a corner post or leg and easier to handle.
  • a further advantageous embodiment of the invention provides that in the opening of the pile stopper spacers are arranged, via which the corner post or the leg is held in the opening at a distance from the pile stopper. This ensures that a sufficient annular gap for the introduction of the bonding layer is present.
  • a further advantageous embodiment of the invention provides that in particular the region of the connecting layer is provided with a corrosion protection, for example with a corrosion protection coating or a coating.
  • a secondary structure according to the invention can also be a cable guide tube or a jetty according to another embodiment of the invention.
  • the foundation structure according to the invention is not limited to lattice structures consisting of corner posts and trusses arranged between the corner posts struts, but also includes structures in which no distinction can be made between corner post and strut (eg "Hexabase-Jacket” or DE 20 2011 101 599 U1 , or other dissolved structural structures, eg tripods).
