Abstract
Description
Die Erfindung betrifft ein Nachgiebigkeitselement zur Integration in einen untertägigen Verbundausbau aus Rinnenprofilen oder Gitterträgern und einer Betonschale gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a compliance element for integration in an underground composite construction of channel profiles or lattice girders and a concrete shell according to the features in the preamble of
Ein Nachgiebigkeitselement ist grundsätzlich im Umfang der
Eine Weiterbildung des Nachgiebigkeitselements der
Die Rinnenprofile oder Gitterträger werden mittels Ort- oder Spritzbeton in eine umfangsseitig des Tunnels oder der Strecke eingebrachte Betonschale eingebettet.The gutter profiles or lattice girders are embedded by means of shotcrete or shotcrete in a concrete shell inserted on the circumference of the tunnel or the track.
Das bekannte Nachgiebigkeitselement hat sich in der Praxis grundsätzlich bewährt. Der Fachmann kann beispielsweise schon während der Bauphase eines Tunnels oder einer Strecke erkennen, welche Kraft aus dem Gebirge auf den Verbundausbau wirkt. Insbesondere jedoch, welche Kraft auf dem Nachgiebigkeitselement lastet. Demzufolge kommt ein Nachgiebigkeitselement vorwiegend in Störungszonen oder bei einem druckhaften Gebirge zum Einsatz. Die Anzahl der jeweils in einen Verbundausbau zu integrierenden Nachgiebigkeitselemente hängt von den örtlichen Gegebenheiten ab.The known compliance element has basically proven itself in practice. For example, during the construction phase of a tunnel or a route, the person skilled in the art can already see which force from the mountain acts on the composite structure. In particular, however, which force rests on the compliance element. Consequently, a compliance element is mainly used in fault zones or in a pressure rock. The number of each to be integrated in a composite expansion compliance elements depends on the local conditions.
Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zu Grunde, ein Nachgiebigkeitselement zur Integration in einen untertägigen Verbundausbau zu schaffen, das ein erhöhtes Widerstandsvermögen gegenüber der Kraft aus dem Gebirge aufweist.The invention is - based on the prior art - the object to provide a compliance element for integration into an underground composite structure, which has an increased resistance to the force from the mountains.
Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Anspruchs 1.The solution to this problem consists according to the invention in the features of
Danach ist nunmehr in wenigstens einen Rohrkörper eines Nachgiebigkeitselements mindestens ein Hohlprofil eingefügt. Ob in diesem Zusammenhang in jeden Rohrkörper ein Hohlprofil eingefügt wird oder ob nur in ausgewählten Rohrkörpern Hohlprofile vorgesehen werden bzw. ob in einen Rohrkörper mehr als ein Hohlprofil eingesetzt wird, hängt von den örtlichen Gegebenheiten ab. Hierbei ist es denkbar, dass der Fachmann unmittelbar vor Ort nach Bedarf Hohlprofile in die Rohrkörper einschiebt. Sind schon vorab die örtlichen Verhältnisse bekannt, so können die Nachgiebigkeitselemente bereits werkseitig entsprechend vorbereitet und in geeigneter Weise mit Hohlprofilen in den Rohrkörpern bereit gestellt werden.Thereafter, at least one hollow profile is now inserted into at least one tubular body of a compliance element. Whether in this context in each tube body, a hollow profile is inserted or whether only in selected tubular bodies hollow sections are provided or whether more than one hollow section is used in a tubular body depends on the local Conditions from. In this case, it is conceivable for the person skilled in the art to insert hollow sections into the tubular body as needed on site. If the local conditions are already known in advance, then the compliance elements can already be appropriately prepared at the factory and provided in a suitable manner with hollow profiles in the tubular bodies.
Um die Position eines Hohlprofils in einem Rohrkörper zu sichern, wird das Hohlprofil nach Anspruch 2 im Rohrkörper zweckmäßig lagefixiert. Auf diese Weise behält es seine vorgesehene Position, bis der Verbundausbau insgesamt fertig gestellt ist.In order to secure the position of a hollow profile in a tubular body, the hollow profile is suitably fixed in position in the tubular body according to claim 2. In this way, it keeps its intended position until the composite construction is completed in its entirety.
Gemäß den Merkmalen des Anspruchs 3 besteht das Hohlprofil aus einem Schlitzrohr, das reib- und formschlüssig in den Rohrkörper gepresst ist.According to the features of
Nach den Merkmalen des Anspruchs 4 kann das Hohlprofil aber auch aus einem umfangsseitig geschlossenen Rohr mit bevorzugt kreisrundem Querschnitt bestehen, das mittels Befestigungselementen im Rohrkörper verklemmt ist. Es sind aber auch andere Querschnitte eines Hohlprofils vorstellbar.According to the features of claim 4, however, the hollow profile can also consist of a circumferentially closed tube with preferably circular cross-section, which is clamped by means of fastening elements in the tubular body. But there are also other cross-sections of a hollow profile conceivable.
Entsprechend Anspruch 5 ist es in diesem Zusammenhang möglich, dass die Befestigungselemente aus im Hohlprofil fixierten Drähten bestehen. Beispielsweise werden in jedem Hohlprofil einander gegenüberliegend zwei Drähte, beispielsweise Schweißdrähte, angepunktet und an den gegenüber den Stirnseiten vorstehenden Enden mit abgebogenen Schenkeln versehen, wobei die in Einschubrichtung vorne liegenden Schenkel um etwa 160° abgebogen sind, so dass sie beim Einführen eines Hohlprofils in einen Rohrkörper zusammengedrückt werden und an der Innenwand des Rohrkörpers gleiten. Die in Einschubrichtung hinten liegenden Schenkel sind um etwa 90° abgebogen. Kontaktieren diese Schenkel die hintere Stirnwand des Rohrkörpers, liegen die in Einschubrichtung vorne liegenden Schenkel frei vor der Stirnseite des Rohrkörpers und können auffedern, so dass dann das Hohlprofil über die Schenkel in Längsrichtung des Rohrkörpers lagefixiert ist.According to claim 5, it is possible in this context that the fastening elements consist of fixed in the hollow profile wires. For example, in each hollow profile opposite one another two wires, such as welding wires, dotted and provided on the opposite ends of the protruding ends with bent legs, wherein the forward leg in the insertion direction are bent by about 160 °, so that they when inserting a hollow profile in a Tube bodies are compressed and slide on the inner wall of the tubular body. The legs in the insertion direction are bent by about 90 °. If these legs contact the rear end wall of the tubular body, the legs lying in the direction of insertion are exposed in front of the end face of the tubular body and can spring open, so that the hollow profile is then fixed in position over the legs in the longitudinal direction of the tubular body.
Eine weitere Ausführungsform von Befestigungselementen wird in den Merkmalen des Anspruchs 6 gesehen. Danach bestehen die Befestigungselemente aus zwischen den Rohrkörper und das Hohlprofil einschiebbaren Federstahlbändern. Beim Einführen eines Hohlprofils in einen Rohrkörper werden auch hierbei zwei bevorzugt in gegenüberliegender Anordnung vorgesehene Federstahlbänder zweilagig abgebogen und in den Spalt zwischen dem Hohlprofil und dem Rohrkörper eingefügt. Beim Einschieben des Hohlprofils in den Rohrkörper gleiten die Federstahlbänder im Rohrkörper und verspannen letztlich aufgrund der ihnen innewohnenden Spreizkraft in der Einsatzposition das Hohlprofil im Rohrkörper.Another embodiment of fasteners is seen in the features of claim 6. Thereafter, the fasteners consist of insertable between the tubular body and the hollow profile spring steel strips. When inserting a hollow profile into a tubular body, two spring steel strips, which are preferably provided in an opposing arrangement, are also bent in two layers and inserted into the gap between the hollow profile and the tubular body. When inserting the hollow profile in the tubular body slide the spring steel strips in the tubular body and ultimately tense due to the inherent spreading force in the use position, the hollow section in the tubular body.
Eine besonders vorteilhafte Ausführungsform der Erfindung besteht gemäß Anspruch 7 darin, dass zwischen den Tragblechen mindestens zwei Lagen mit Rohrkörpern und darin eingefügten Hohlprofilen vorgesehen sind, wobei zwischen jeweils zwei Lagen ein Trennblech angeordnet ist. Wie viele Rohrkörperlagen und Trennbleche erforderlich sind, hängt von den jeweiligen örtlichen Gegebenheiten ab. Denkbar sind beispielsweise drei oder vier Lagen. Auch die Anzahl der Rohrkörper mit Hohlprofilen in den einzelnen Lagen kann von Einsatzpunkt zu Einsatzpunkt variieren.A particularly advantageous embodiment of the invention according to
Schließlich bildet es entsprechend den Merkmalen des Anspruchs 8 eine grundsätzliche Weiterbildung des erfindungsgemäßen Grundgedankens, dass die Rohrkörper und/oder die Hohlprofile in einer Lage im Vergleich zu den Rohrkörpern und/oder den Hohlprofilen in einer anderen Lage voneinander abweichende Wanddicken und/oder Durchmesser aufweisen. So ist es beispielsweise denkbar, dass bei einem Nachgiebigkeitselement mit drei Lagen die obere Lage keine Hohlprofile in den Rohrkörpern vorsieht, die mittlere und untere Lage aber Hohlprofile in den Rohrkörpern aufweisen, wobei jedoch die Wanddicken der Hohlprofile in der unteren Lage größer sind als die der Hohlprofile in den Rohrkörpern der mittleren Lage. Die Wanddicke kann im Rahmen der Erfindung auch mit verschiedenen Durchmessern der Hohlprofile variiert werden. Darüber hinaus kann eine Kombination der Durchmesser der Rohrkörper und ihrer Wanddicken mit den Durchmessern und/oder Wanddicken der Hohlprofile erfolgen. Auch die Anzahl der Hohlprofile in den Rohrkörpern kann von Einsatzpunkt zu Einsatzpunkt variieren.Finally, it forms according to the features of
Im Rahmen der erfindungsgemäßen Maßnahmen kann mithin ein kontrolliertes Nachgiebigkeitsverhalten erzielt werden, wobei die Tragfähigkeit eines Nachgiebigkeitselements auf die der benachbarten Rinnenprofile oder Gitterträger exakt abgestimmt werden kann. Wenn mithin ein Bogenausbau aus Rinnenprofilen beginnt, sich hinsichtlich der Rinnenprofile relativ zueinander zu verschieben oder Gitterträger eines Ausbaus beginnen einzuknicken, so beginnt auch das Nachgiebigkeitselement sich zu verformen und Last aufzunehmen.In the context of the measures according to the invention, therefore, a controlled compliance behavior can be achieved, wherein the carrying capacity of a compliance element can be exactly matched to that of the adjacent channel profiles or lattice girders. Thus, when a bow assembly of gutter profiles begins to shift relative to each other with respect to the gutter profiles, or lattice girders of a construction begin to buckle, the compliance element also begins to deform and absorb load.
