Abstract: A tower structure particularly suited for a wind turbine includes a lower tower section formed of concrete and an upper tower section formed of steel. A transition system connects the upper tower section to the lower tower section, the transition system including a concrete component having a tubular wall with a base portion fixed on the lower tower section and a head portion connected to the upper tower section. The head portion extends radially outward beyond the upper tower section. A plurality of first tensioning tendons extend longitudinally at least partially through the tubular wall and are anchored to the concrete component at a top face of the head portion at locations radially outward of the upper tower section.

Abstract: A system and method are provided for manufacturing a tower structure. Accordingly, an interlocking form ring is additively manufactured with a first printhead assembly. The interlocking form ring defines a plurality of recesses in a radially inner or a radially outer face. A cementitious material is deposited within one or more of the recesses with a second printhead assembly. At least one reinforcing member is positioned within the recess with the second printhead assembly. The second printhead assembly is positioned adjacent to the cementitious material during the curing thereof so as to provide a slip form for the curing of the cementitious material.

Abstract: A system for manufacturing a structure includes a supporting frame assembly moveable in a vertical direction of the structure. Further, the system includes an additive printing assembly secured to the supporting frame assembly. The additive printing assembly includes at least one printer head configured to dispense a first cementitious material. The system also includes a reinforcement dispensing assembly supported by the supporting frame assembly. Thus, the reinforcement dispensing assembly is configured to automatically and continuously dispense a plurality of reinforcing members as the structure is printed and built up via the at least one printer head and as the supporting frame assembly moves in the vertical direction.

Abstract: A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.
