Abstract: The invention relates to a method for forming a connection between two pipe segments of different widths, preferably of a tower-like structure, in particular of a wind turbine. In order to be able to connect pipe segments of different widths more easily, reliably and cost-effectively to one another, it is provided that the wider pipe segment is pushed with one end partially over an end of the narrower pipe segment, that the pipe segments are positioned apart from one another by forming an annular gap between the pipe segments, that in the annular gap between the two pipe segments a separating layer extending in the longitudinal direction of the pipe segments and/or in the radial direction is provided, that the annular gap adjacent to the separating layer and at least one side of the separating layer is at least partially cast with a casting compound, that during the hardening of the casting compound the casting compound forms a firm connection on one side of the separating layer with only one of the pipe segments and/or the casting compound forms a firm connection on the other side of the casting compound, only with the other pipe segment and that the pipe segments after the hardening of the casting compound are separated again along the separating layer with the assigned separate connecting elements in particular formed by the hardened casting compound.

Abstract: A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow pole section modules, each module having an elongated structure with a base end and an opposed tip end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the tip end of a base module with the base end of an additional module. One or more than one of the modules forming the elongated modular pole structure comprise a composite material having fire resistant properties.

Abstract: A foundation for wind turbine towers of the type used to support both metal towers and concrete towers of wind turbines that uses precast concrete or metal beams, combined with small footings concreted in situ, the beams being structurally connected at the central part of the foundation by the elements of connection and of support of the tower is disclosed. The invention affords the main advantage of achieving a notable reduction in the volume of materials used, both concrete and rebar, with a great reduction in assembly time and the consequent great economic savings as well as its ease of adaptation to different terrains is presented.

Abstract: Spiral forming devices, systems, and methods can be used to join edges of a of a stock material, in a curved configuration, along one or more joints to form tubular structures, such as conical and/or cylindrical structures (e.g., frusto-conical structures). A planar form of the stock material can be formed from a plurality planar sheets coupled to one another in an abutting relationship. By controlling relative orientation and shapes of the plurality of planar sheets forming the stock material and/or by controlling a position of a roll bender used to curve the planar form of the stock material into the curved configuration, the curved configuration of the stock material can be controlled through transitions between sheets to facilitate rolling the sheets to a desired diameter with a reduced likelihood of dimples or other errors and to facilitate fit up between adjacent sheets in the curved configuration.
