Abstract
Description
Die Erfindung betrifft einen Turm für eine Windenergieanlage mit einem unteren gitterturmförmigen Turmabschnitt mit wenigstens drei Eckstielen und einem oberen rohrförmigen Turmabschnitt mit kreisförmigem Querschnitt, wobei die Eckstiele im Anschlussbereich von unterem Turmabschnitt und oberem Turmabschnitt auf dem Umfang des kreisförmigen Querschnitts des rohrförmigen Turmabschnitts angeordnet sind, und wobei die Eckstiele aus wenigstens einem Eckstielelement mit einem äußeren und einem inneren Profil gebildet sind.The The invention relates to a tower for a wind turbine with a lower lattice tower-shaped tower section with at least three corner posts and an upper tubular tower section with circular Cross-section, with the corner handles in the connection area of lower Tower section and upper tower section on the circumference of the circular cross section of the tubular Tower section are arranged, and wherein the corner stems of at least a corner handle with an outer and an inner profile are formed.
Gittertürme sind aus einer Vielzahl von Anwendungen, beispielsweise als Strommasten für Überlandleitungen oder Funkmasten zur Befestigung von Antennen, bekannt. Sie bestehen regelmäßig aus drei oder vier Eckstielen, die einen drei- bzw. viereckigen Turmgrundriss bilden. Entlang ihrer Längserstreckung sind die Eckstiele häufig aus mehreren Eckstielelementen gebildet, die miteinander mittels Laschen und die Laschen an den Eckstielelementen befestigenden Befestigungsmitteln verbunden. Üblicherweise werden zwei Eckstielelemente an ihren Stoßkanten dadurch zusammengefügt, dass eine Lasche, i. e. ein in Längsrichtung der Elemente ausgerichtetes Blech, die Stoßkanten überbrückend angeordnet wird, und die Lasche sowohl an dem einen Ende des einen Elements als auch am benachbarten Ende des anderen Elements beispielsweise angeschraubt wird. Zur Standfestigkeit des Gitterturms tragen die Eckstiele miteinander verbindende Streben bei.Lattice towers are from a variety of applications, such as electricity pylons for power lines or radio masts for mounting antennas, known. They persist regularly out three or four corner stems, which form a triangular or quadrangular tower layout form. Along its length The corner handles are common formed by several corner stick elements, which means each other Tabs and the tabs on the Eckstielelementen fastening fasteners connected. Usually two Eckstielelemente be joined together at their abutting edges that a Flap, i. e. one in the longitudinal direction the elements aligned sheet metal, the jumper edges is bridged, and the tab on both the one end of the one element as well screwed on the adjacent end of the other element, for example becomes. For stability of the lattice tower, the corner handles bear each other connecting aspirations.
Werden Gittertürme für Windenergieanlagen verwendet, bei denen auf einem unteren gitterturmförmig ausgebildeten Turmabschnitt ein oberer rohrförmiger Turmabschnitt aufgesetzt ist, sind aufgrund der Torsionsbeanspruchung und der hohen Betriebsfestigkeitsanforderung besondere Anforderungen an den Gitterturm gestellt. Hierbei wäre es vorteilhaft, wenn die Eckstielelemente als Hohlprofil ausgebildet werden könnten. Allerdings stellt sich damit das Problem, wie zwei aneinander angrenzende Elemente miteinander verbunden werden sollen, da in den lediglich an seinen Enden zugänglichen Hohlraum des Hohlprofils eindringende Schrauben nicht gekontert werden können, da dieser Hohlraum beim Zusammenfügen der Elemente geschlossen wird.Become lattice towers used for wind turbines, in which on a lower lattice tower shaped tower section an upper tubular one Tower section is attached, are due to the torsional stress and the high durability requirement special requirements placed on the lattice tower. It would be advantageous if the Eckstielelemente could be formed as a hollow profile. Indeed This raises the problem of how two adjacent elements interact with each other should be connected, as in the only accessible at its ends Cavity of the hollow profile penetrating screws can not be countered can, because this cavity is closed when joining the elements becomes.

Nachteil dieser Konstruktion ist jedoch, dass die Verbindung des unteren mit dem oberen Turmabschnitt aufgrund der speziell in diesem Bereich auftretenden Belastungen ungenügend erscheint.disadvantage However, this construction is that the connection of the lower with the upper tower section due especially in this area Insufficient loads occur appears.
Es ist daher Aufgabe der Erfindung, einen Turm mit einem unteren gitterturmförmigen Turmabschnitt mit wenigstens drei Eckstielen und einem oberen rohrförmigen Turmabschnitt mit kreisförmigem Querschnitt bereitzustellen, der eine besonders feste und dauerhafte Verbindung zwischen dem unteren gitterturmförmigen Turmabschnitt und dem oberen rohrförmigen Turmabschnitt ermöglicht.It is therefore an object of the invention, a tower with a lower lattice tower-shaped tower section with at least three corner posts and an upper tubular tower section with circular To provide cross-section, which is a particularly solid and durable Connection between the lower lattice tower-shaped tower section and the upper one tubular Tower section allows.
Die Aufgabe wird durch einen Turm für eine Windenergieanlage mit den Merkmalen von Anspruch 1 gelöst. Die von Anspruch 1 abhängigen Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The Task is through a tower for a wind turbine solved with the features of claim 1. The dependent on claim 1 under claims give advantageous embodiments of the invention again.
Grundgedanke der Erfindung ist es, die beiden bevorzugt mit einander verschweißten V-förmigen Profile eines Eckstiels in einem dem rohrförmigen Turmabschnitt zugewandten Ab schnitt voneinander zu trennen, wobei das äußere V-förmige Profil von schlitzförmigen Aufnahmen der rohrförmigen Turmwandung aufgenommen ist und die in diesem Abschnitt freien Enden des inneren V-förmigen Profils mit der Innenwandung des rohrförmigen Turmabschnitts verbunden, bevorzugt verschweißt sind.basic idea The invention is the two preferred with each other welded V-shaped profiles of a corner handle in a tubular Tower section facing Ab cut separate from each other, wherein the outer V-shaped profile of slotted Images of the tubular tower wall is included and in this section free ends of the inner V-shaped Profile connected to the inner wall of the tubular tower section, are preferably welded.
Durch diese Ausbildung ist es ermöglicht, dass beispielsweise die bei einer Windenergieanlage auftretenden Kräfte aus den Verbandsdiagonalen durch das ungestörte Material durchgeleitet werden und keine Abminderungen bezüglich irgendwelcher Kerbfälle gemacht werden müssen. Die gewählte Form des Innen- und Außenprofils ermöglicht es, die Verbandswinkel kollisionsfrei an die freien Schenkel des Außenprofils zu führen und leicht und ohne hohe Toleranzforderung Laschenvollstöße herzustellen. Die vorgesehenen Öffnungen („Handlöcher”) ermöglichen die einfache Verschraubung auch der Innenlaschen. Die Schrauben werden von Außen eingesteckt, sodass die Mutter und offenen Gewindegänge der Witterung nur sehr gering ausgesetzt sind. Sollten sich später, z. B. durch ungleichmäßige Setzung des Turmes, Schiefstellungen ergeben, kann der Turm durch nachträglich hergestellte kürzere oder längere Laschen wieder neu ausgerichtet werden.This design makes it possible, for example, for the forces occurring in a wind energy plant to be transmitted from the dressing diagonals through the undisturbed material, and for there not to be any reductions in respect of any notch cases. The selected shape of the inner and outer profile makes it possible to collision-free the dressing angle to the free legs of the outer profile and easily and without high tolerance requirement to produce Laschenvollstöße. The openings provided ("hand holes") allow easy screwing and the inner plates. The screws are inserted from the outside, so that the nut and open threads of the weather are exposed only very slightly. Should later, z. B. by uneven placement of the tower, skewed, the tower can be realigned by subsequently produced shorter or longer tabs again.
