Description

Die Erfindung bezieht sich auf einen Turm einer Windkraftanlage mit einem Verbindungsstück zwischen einem unteren rohrförmigen Spannbetonteil und einem oberen rohrförmigen Stahlteil. Ausgegangen wird also von einem Turm, der – vereinfacht gesehen – aus zwei Teilen besteht, einem Turmfuß aus vorgespanntem Stahlbeton und einem aufgesetzten Stahlturm.The invention relates to a Tower of a wind turbine with a connector between a lower tubular Prestressed concrete part and an upper tubular steel part. Went out is therefore made up of one tower, which - seen simply - from two Parts consists of a tower base prestressed concrete and an attached steel tower.

Nach dem gegenwärtigen Stand der Technik werden für Türme von Windkraftanlage Stahlrohrtürme, Stahlgittermasten oder Spannbetonrohrtürme angewendet. Stahlrohrtürme werden aus geschlossenen Ringen, die nach oben konisch verlaufen können, montiert. Dieses Konstruktionsprinzip, das auf der Verwendung der geschlossenen Ringe beruht, erreicht mit zunehmender Turmhöhe seine Grenze, da Türme mit größerem Ringdurchmesser erforderlich werden. Die zulässige Breite von Bauteilen, die auf der Straße transportiert werden, darf etwa vier Meter nicht überschreiten. Damit lässt dieses Konstruktionsprinzip keine unbegrenzte Vergrößerung der geometrischen Abmessungen zu.According to the current state of the art for towers Wind turbine steel tube towers, Steel lattice masts or prestressed concrete tube towers are used. Tubular steel towers of closed rings which may be tapered upwardly mounted. This design principle, based on the use of the closed Based rings, achieved with increasing tower height its limit, as towers with larger ring diameter become necessary. the permissible Width of components that can be transported on the road not exceed about four meters. With that leaves this design principle is not an unlimited enlargement of the geometric dimensions, increase.

Spannbetontürme werden vor Ort monolithisch gefertigt und vorgespannt oder werden aus Stahlbetonfertigteilen montiert, die miteinander verspannt werden. Nachteilig bei der Errichtung von Spannbetonrohrtürmen ist die lange Zeit für ihre Errichtung auf der Baustelle und der hohe Aufwand für das Aufbringen der Vorspannkraft. Bekannt sind Ausführungen in Fertigteilbauweise, bei der aufeinandergestapelte ringförmige Stahlbetonteile vertikal mit Litzenspanngliedern verbunden und verspannt werden.Prestressed concrete towers become monolithic on site manufactured and prestressed or are made of precast reinforced concrete mounted, which are clamped together. A disadvantage in the construction of prestressed concrete tube towers is the long time for their construction on the construction site and the high effort for the installation the biasing force. Designs in prefabricated construction are known, with the stacked ring-shaped reinforced concrete parts vertically connected and tensioned with strand tendons.

Bei nicht vorgespannten Stahlbetonrohrtürmen würden infolge der Einwirkungen aus Wind und der maschinentechnischen Anlage der Windkraftanlage horizontale Risse auftreten, da der Beton keine Zugspannungen aufnehmen kann. Diese Einwirkungen variieren zusätzlich in ihrer Richtung je nach Stellung des Rotors und der Windrichtung, sodass sich im Turmquerschnitt an jeder Stelle Zugspannungen in zeitlicher Abfolge einstellen. Um diese Zugbeanspruchungen, die zu einer bisher nicht quantifizierbaren Ermüdung des Betons führt, zu vermeiden, wird nach gegenwärtigem Stand der Technik für Türme von Windkraftanlagen zugspannungsfreier Beton im Zustand der Gebrauchstauglichkeit verlangt.With non-prestressed reinforced concrete tube towers would result the effects of wind and the mechanical engineering of the Wind turbine horizontal cracks occur because the concrete has no tensile stress can record. These actions also vary in their direction the position of the rotor and the wind direction, so that the tower cross-section set tensile stresses in chronological order at every point. To these tensile stresses, which led to a previously unquantifiable fatigue the concrete leads, to avoid, according to current The art of towers of Wind turbines zugspannungsfreier concrete in the state of serviceability required.

Vorspannkräfte werden über Verankerungen konzentriert in den Beton eingeleitet. Bei Einleitung senkrecht verlaufender Vorspannkräfte über Verankerungskörper am Kopf des Betonschafts eines Spannbetonrohrturms treten quer zur Spannrichtung in einem Verankerungsbereich Zugkräfte im Beton auf. Die Kombination mit wechselnden Einwirkungen aus Wind und maschinentechnischer Anlage kann zu Ermüdungserscheinungen im Beton und somit zu Zerstörungen führen. Prestressing forces are concentrated via anchors introduced into the concrete. Upon initiation of vertically extending Preload forces on anchoring body on The head of the concrete shaft of a prestressed concrete tube tower tread across Tensioning direction in an anchoring region of tensile forces in the concrete to. The combination with changing effects from wind and machine technology can cause signs of fatigue in the concrete and thus to destruction to lead.

Im Gegensatz zum Turm aus Beton kann ein Stahlturm Zug- und Druckspannungen gleichermaßen aufnehmen. Wird ein Stahlrohr mit Hilfe von Schrauben verbunden auf einen Betonturm gesetzt, werden die im Stahlrohr auftretende Zugspannungen an den Verbindungspunkten konzentriert in der Hauptbeanspruchungsrichtung vertikal in den Beton übertragen, was zu den oben beschriebenen Schädigungen des Betons führen wird. Beim unmittelbaren Verbinden des Stahlrohrs durch Vorspannglieder mit dem Betonturm werden Zugspannungen im Betonturm in der Hauptbeanspruchungsrichtung vermieden, jedoch können durch die konzentrierte Krafteinleitung über die Verbindungen quergerichtete Zugspannungen im Beton auftreten.Unlike the concrete tower a steel tower absorb tensile and compressive stresses equally. A steel pipe is connected to a concrete tower using screws are set, the tensile stresses occurring in the steel tube at the Connection points concentrated in the main stress direction vertically transferred to the concrete, which will lead to the damage to the concrete described above. When connecting the steel pipe directly with tendons with the concrete tower tensile stresses in the concrete tower in the main direction of stress avoided, but can through the concentrated application of force across the connections Tensile stresses occur in the concrete.

Aus der DE 198 23 650 C2 ist ein Verfahren zum Herstellen von hohen, hohlen, turmartigen Bauwerken, insbesondere von Türmen für Windkraftanlagen, bekannt. Dieses Verfahren beruht auf der Vorfertigung von transportfähigen, komplett vorbehandelten, fertigen Einzelschalungsteilen. Dabei kann die Bewehrung entweder komplett an der Außen- und/oder an der Innenschalung fabrikmäßig angeordnet sein. Die Montage vor Ort erfolgt zum Beispiel durch einfache Schraub-Steckverbindungen. Dabei werden die fabrikmäßigen vorgefertigten Modul-Einzelschalungsteile vor Ort zu Schalungsrohrschüssen für die Innen- und Außenschalung zusammengebaut und dadurch eine verlorene Schalung gebildet, in der sich die vorgefertigte Stahlarmierung befindet. Die einzelnen Schalungsrohrschüsse der Innen- und Außenschalung werden z.B. sektionsweise übereinandergestülpt und miteinander verbunden, bis die angestrebte Höhe in dieser Bauweise erreicht ist. Abschnittsweise wird der Ringraum zwischen den äußeren Schalungsrohrschüssen und den inneren Schalungsrohrschüssen mit Fertigbeton verfüllt.From the DE 198 23 650 C2 is a method for producing high hollow tower-like buildings, particularly of towers for wind turbines, known. This method is based on the prefabrication of transportable, completely pretreated, finished single formwork parts. Here, the reinforcement either be disposed completely on the outside and / or on the inner formwork factory default. On-site assembly is carried out, for example, using simple screw plug connections. The original producer prefabricated module-individual formwork parts are assembled on site to form pipe sections of the inner and outer formwork, thereby forming a permanent formwork, the prefabricated steel reinforcement is in the. The individual formwork pipe sections of the inner and outer formwork are, for example, slipped over each other and connected to each other until the desired height is reached in this construction. Section, the annular space between the outer casing pipe sections and the inner formwork pipe sections is filled with ready-mixed concrete.
