Abstract
Description
Die Erfindung betrifft einen Bauwerk mit einer Umlenkstelle für ein korrosionsgeschütztes Zugglied , insbesondere für ein Schrägseil am Pylon einer Schrägseilbrücke.The invention relates to a building with a deflection point for a corrosion-protected tension member, in particular for a stay cable on the pylon of a cable-stayed bridge.
Bei Schrägseilbrücken ist es bekannt, die im Winkel zueinander verlaufenden Schrägseile, mit denen der Fahrbahnträger gegenüber einem Pylon abgespannt ist und die meist aus einem Bündel von Einzelelementen wie zum Beispiel Stahldrahtlitzen bestehen, mit dem Pylon kraftübertragend zu verbinden. Dies kann einmal dadurch geschehen, dass die aus unterschiedlichen Richtungen kommenden Schrägseile im Pylon enden und dort - gegebenenfalls einander überkreuzende - verankert sind; hierdurch ist eine Vielzahl von Verankerungsvorrichtungen erforderlich. Eine andere Möglichkeit besteht darin, dass die Schrägseile im Pylon sattelartig umgelenkt werden, wobei die rechtwinklig zur Schrägseilachse verlaufenden Laibungskräfte über den Sattel auf den Pylon abgetragen werden.In cable-stayed bridges, it is known to interconnect the angle cables running each other, with which the roadway carrier is braced against a pylon and usually consist of a bundle of individual elements such as steel wire strands, with the pylon force transmitting. This can happen once by the fact that the cables coming from different directions end in the pylon and there - are anchored - possibly crossing each other; As a result, a variety of anchoring devices is required. Another possibility is that the stay cables in the pylon are deflected in the manner of a saddle, wherein the soffit forces running at right angles to the cable-stayed axis are removed via the saddle to the pylon.
Im Falle von Beschädigungen eines solchen Schrägseils, zum Beispiel durch Korrosionserscheinungen an den aus Stahl bestehenden Zugelementen, muss die Möglichkeit bestehen, ein solches Schrägseil auswechseln zu können. Hierzu ist bei einer bekannten Lösung im Pylon ein sattelförmig gekrümmter Kanal gebildet, in den jeweils ein Schrägseil eingeschoben werden kann (
Zur Stabilisierung und zur Erzielung eines Verbundes zwischen den einzelnen Zugelementen des Bündels und dem Sattelrohr sind die verbliebenen Hohlräume mit einem erhärtenden Material, zum Beispiel Zementmörtel, verpresst. Zur Verbesserung des Verbundes mit dem erhärtenden Material können die Zugelemente, also zum Beispiel die Stahldrahtlitzen, zumindest im Scheitelbereich vorzugsweise durch Sandstrahlen aufgeraut sein.To stabilize and achieve a bond between the individual tension elements of the bundle and the seat tube, the remaining cavities are pressed with a hardening material, for example cement mortar. To improve the bond with the hardening material, the tension elements, ie, for example, the steel wire strands, can be roughened, preferably by sandblasting, at least in the apex region.
Bei der bekannten Lösung ist das Sattelrohr außerhalb des Pylons mittels Flanschringen unmittelbar mit der Verrohrung des Bündels im freien Bereich des Schrägseils verbunden. Dies hat zur Folge, dass der im Pylon gebildete Kanal der, um ein Auswechseln des Bündels mit dem Sattelrohr zu ermöglichen, einen relativ großen Querschnitt, zumindest eine größere Höhe aufweisen muss als der Durchmesser des Bündels, an den stirnseitigen Ein- bzw. Austrittsstellen des Schrägseils offen ist. Diese Öffnung ist nachteilig, weil von dort aus Umwelteinflüsse einwirken, auch Tiere, insbesondere Vögel, eindringen können, was zu Verschmutzungen und Korrosionserscheinungen führen kann.In the known solution, the seat tube outside of the pylon by means of flange rings directly with the casing of the bundle in the free area of the stay cable connected. The result of this is that the channel formed in the pylon, which in order to allow replacement of the bundle with the seat tube, must have a relatively large cross-section, at least a greater height than the diameter of the bundle, at the frontal entry or exit points of the bundle Cable stayed is open. This opening is disadvantageous because from there on environmental influences act, animals, especially birds, can penetrate, which can lead to contamination and corrosion phenomena.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine einfache und wirtschaftliche, vor allem aber auch den statischen Erfordernissen Rechnung tragende Möglichkeit aufzuzeigen, um bei einer solchen Schrägseilbrücke die Öffnungen des Führungskanals für das Schrägseil zu verschließen.Against this background, the invention has the object to show a simple and economical, but above all, the static requirements account bearing possibility to close the openings of the guide channel for the stay cable in such a cable-stayed bridge.
Nach der Erfindung wird diese Aufgabe durch die im Anspruch 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in claim 1.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous developments emerge from the subclaims.
Bei der Lösung der Aufgabe geht die Erfindung davon aus, die stirnseitigen Öffnungen des Führungskanals dadurch zu verschließen, dass die Verrohrung im freien Bereich des Schrägseils mittelbar oder unmittelbar an das Bauwerk, also den Pylon, angeschlossen wird. Aus Gründen der Fixierung des Schrägseils gegen Längsbewegungen im Bereich des Sattels kann hierbei aber auf das solche Kräfte durch Verbund übertragende Sattelrohr nicht verzichtet werden. Deshalb muss Sorge dafür getragen werden, dass die einzelnen Zugelemente auch bei unvermeidlichen Einbautoleranzen, Temperaturbewegungen oder Rohrschwingungen bei ihrem Austritt aus dem starren Sattelrohr nicht beschädigt oder sonst wie beeinträchtigt werden.In the solution of the problem, the invention is based on the fact that the frontal openings of the guide channel to be closed by the fact that the tubing in the free area of the cable is directly or indirectly connected to the building, so the pylon. For reasons of fixing the stay cable against longitudinal movements in the saddle but this can not be dispensed with such forces by composite transmitting seat tube. Therefore, care must be taken to ensure that the individual tension elements are not damaged or otherwise impaired even in the case of unavoidable installation tolerances, temperature fluctuations or tube vibrations when they exit the rigid seat tube.
Die erfindungsgemäße Lehre, das kreisbogenförmig gekrümmte Sattelrohr über den tangentialen Austritt des Bündels hinaus so weit weiterzuführen, dass das Bündel ohne Gefahr einer Anlage am Ende des Sattelrohrs frei liegt, ist eine sehr einfache Möglichkeit um sicherzustellen, dass sich das Litzenbündel auch bei Einbautoleranzen ohne die Gefahr einer Anlage oder gar eines Knicks am Ende des Sattelrohrs abhebt. Damit entfällt eine aufwendige trompetenförmige Aufweitung des Sattelrohres am Ende, wodurch auch das Aussparungsrohr, das im Pylon den sattelförmigen Führungskanal für das Schrägseil bildet, bei der Forderung nach Auswechselbarkeit im Durchmesser kleiner ausgeführt werden kann, als wenn das Sattelrohr in seinem Endbereich bei Austritt des Bündels aufgeweitet wäre.The teaching according to the invention of continuing the circular arcuate saddle tube beyond the tangential outlet of the bundle so that the bundle is exposed without risking contact at the end of the saddle tube is a very simple way of ensuring that the bundle of strands does not suffer any misalignment Danger of a plant or even a kink at the end of the seat tube lifts. This eliminates a complex trumpet-shaped widening of the saddle tube at the end, whereby the recess tube, which forms the saddle-shaped guide channel for the stay cable in the pylon, smaller in the demand for interchangeability in diameter can be performed as if the seat tube would be widened in its end at the outlet of the bundle.

Im Pylon 2 ist durch ein Aussparungsrohr 5 mit ovalem Querschnitt ein an den Stirnseiten offener, mit dem Radius R sattelförmig gekrümmter Kanal 6 gebildet, in den das Schrägseil 1 von außen her eingeschoben werden kann. Das Bündel 3 selbst ist im Bereich seiner Hindurchführung durch den Pylon 2 in einem ebenfalls kreisbogenförmig gekrümmten Sattelrohr 7 aus Stahl geführt, innerhalb dessen die einzelnen Zugelemente des Bündels 3 durch Einpressmörtel 8 in Verbund mit dem Sattelrohr 7 gebracht sind.In the
Im Scheitelbereich 9 der Umlenkung befindet sich ein vertieftes Sattellager 10 mit einer Ausnehmung 11, in die eine mit dem Sattelrohr 7 fest, zum Beispiel durch Schweißen, verbundene Knagge 12 einrastet. Diese Art der Verankerung gewährleistet bei voller Auswechselbarkeit des Schrägseils 1 zuverlässig die Verhinderung von Längsbewegungen schon während der Montage des Schrägseils und ermöglicht zugleich die Aufnahme von in Längsrichtung des Schrägseils 1 auftretenden Differenzkräften. Durch diese Konstruktion wird gewährleistet, dass das gesamte Schrägseil 1 zum Auswechseln mit dem Sattelrohr 7 angehoben werden kann, bis die Knagge 12 von der Ausnehmung 11 frei kommt; die ovale Form des Aussparungsrohrs 5 lässt hierzu nach oben hin genügend Platz. Danach kann das Schrägseil 1 mit dem Sattelrohr 7 entlang der kreisbogenförmigen Krümmung des Umlenkbereichs gemäß dem Radius R aus dem Kanal 6 herausgezogen werden.In the apex region 9 of the deflection there is a recessed saddle bearing 10 with a recess 11 into which a firmly connected to the

Zur Herstellung einer lösbaren Verbindung zwischen dem Anschlussrohr 14 und der Verrohrung 4, hier in Gestalt des Übergangsrohrs 15, besitzt das Anschlussrohr 14 am verrohrungsseitigen Ende einen Innenflansch 19, gegen den von außen her ein Außenflansch 20 des Übergangsrohrs 15 anliegt. Die kraftschlüssige Verbindung zwischen dem Übergangsrohr 15 und dem Anschlussrohr 14 wird durch eine achsparallele Verschraubung 21 gewährleistet, die gegen einen losen Flanschring 22 wirkt. Durch den von außen anlegbaren Flanschring 22 wird die Montage der Verrohrung erheblich vereinfacht. Die Verschraubungskraft wirkt auf den - angeschweißten - PE-Flansch 20 über einen Ring 23 aus elastischem Material, wie zum Beispiel Gummi oder Kunststoff, wodurch Zwängungsspannungen aus etwa auftretenden Winkelfehlern vermieden werden. Außerdem wird dadurch eine weichere Lastübertragung von Rohrschwingungen auf die Verschraubung 21 erreicht.To produce a detachable connection between the
