Description

Die Erfindung betrifft ein Rückhaltesystem gemäß dem Oberbegriff des Anspruches 1.The invention relates to a restraint system according to the preamble of claim 1.

Durch die DE 100 26 621 A wurde ein Rückhaltesystem der eingangs erwähnten Art bekannt, bei dem Dilatationselemente vorgesehen sind, die im Wesentlichen durch eine Zylinder-Kolbenanordnung gebildet sind, bei denen der Kolben mit einer kleinen Bohrung versehen ist, die ein Überströmen eines Fluids von einer Seite des Kolbens zur anderen Seite des Kolbens ermöglichen. Dadurch ist eine langsame Bewegung des Kolbens, z.B. aufgrund von Wärmedehnungen der Betonelemente, problemlos möglich, wogegen rasche Änderungen des Kolbens gegenüber dem Zylinder, z.B. aufgrund eines Anpralls eines Fahrzeuges an die Elemente des Rückhaltesystems, verhindert werden. Dadurch ist es möglich Wärmedehnungen aufzunehmen und trotzdem einen stabilen Verbund der Betonelemente sicherzustellen.DE 100 26 621 A has disclosed a restraint system of the type mentioned in the introduction, are provided in the dilation elements, which essentially by a cylinder-piston assembly are formed, in which the piston is provided with a small bore, an overflow of a fluid from one side of the piston to the other side of the piston enable. Thereby, a slow movement of the piston, e.g. owing to Thermal expansion of the concrete elements, easily possible, whereas rapid changes in the Piston opposite the cylinder, e.g. due to an impact of a vehicle to the Elements of the restraint system, be prevented. This makes it possible To absorb thermal expansion and still a stable composite of concrete elements sure.

Mit solchen Dilatationselementen ist es auf einfache Weise möglich im Bereich von gerade verlaufenden Fahrbahnen die Wärmedehnungen aufzunehmen. Allerdings ist es mit der bekannten Lösung nicht möglich im Bereich von Kurven, in denen Wärmedehnungen auch zu transversalen Verschiebungen führen, diese optimal aufzunehmen.With such dilation elements, it is easily possible in the area of straight running lanes absorb the thermal expansion. However, it is with the known solution not possible in the range of curves in which thermal expansions too transversal shifts lead to these optimally.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und ein Rückhaltesystem der eingangs erwähnten Art vorzuschlagen, bei dem auch in Kurvenabschnitten einerseits ein sicherer Ausgleich von Wärmedehnungen auch in transversaler Richtung sichergestellt ist.The aim of the invention is to avoid these disadvantages and a restraint system of the beginning to suggest the type mentioned, in which, on the one hand in the curve sections a safer Compensation of thermal expansion is ensured even in the transverse direction.

Erfindungsgemäß wird dies bei einem Rückhaltesystem der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.This is according to the invention in a restraint system of the type mentioned by the characterizing features of claim 1 achieved.

Durch die vorgeschlagenen Maßnahmen ist sichergestellt, dass sich die Elemente, z.B. Betonelemente, in Kurvenabschnitten im Bereich einer Dilatationsfuge einer Brückenkonstruktion um einen begrenzten Betrag transversal verschieben können. Durch die Gleitlager im Bereich der der Dilatationsfuge näheren Endbereichen der dieser benachbarten Elemente, die über ein Dilatationselement miteinander verbunden sind, können sich diese zur Aufnahme von Querverschiebungen gemeinsam verdrehen. Auch sind Fälle denkbar in welchen es ausreichend ist, dass sich nur ein Element zur Aufnahme von Querverschiebungen verdrehen kann. Durch die Möglichkeit einer transversalen Verschiebung bestimmter Elemente können diese in Kurvenabschnitten die aufgrund von Wärmedehnungen auftretenden transversalen Bewegungen der Brücke gegenüber deren Widerlager aufnehmen. Dabei ist die Wahl der Länge des Dilatationselementes in Verbindung mit einem möglichen Spiel von Bedeutung, das in Kupplungen mit Elementen des Rückhaltesystems vorhanden ist, die an jene Elemente angrenzen, die über ein Dilatationselement miteinander verbunden sind. Durch die Gleitlager, die nahe der Dilatationsfuge angeordnet sind und die Verbindung der an die Dilatationsfuge angrenzenden Elemente über das Dilatationselement, das zwar eine gegenseitige Verschiebung dieser Elemente in deren axialer Richtung ermöglicht, nicht aber eine transversale gegenseitige Verschiebung dieser Elemente wird eine gemeinsame Verdrehung dieser Elemente ermöglicht. Damit können Bewegungen der Brücke durch eine Drehung dieser Element aufgenommen werdenThe proposed measures ensure that the elements, e.g. Concrete elements, in curved sections in the area of a dilatation joint Bridge construction can move transversely by a limited amount. By the Plain bearing in the area of the dilatation joint closer end portions of this adjacent Elements that are connected to each other via a dilatation element, these can be used for Twist the recording of transverse displacements together. Also, cases are conceivable in which it is sufficient that only one element for receiving transverse displacements can twist. By the possibility of a transversal shift of certain Elements can do this in curve sections due to thermal expansion absorb occurring transversal movements of the bridge against its abutment. The choice of the length of the dilation element in connection with a possible Play of importance, which is present in couplings with elements of the restraint system, which adjoin those elements which are connected to each other via a dilation element. Through the plain bearings, which are arranged near the dilatation joint and the connection of the the dilatation joint adjoining elements via the dilatation, which although a mutual displacement of these elements in their axial direction allows, but not a transversal mutual shift of these elements becomes a common Twisting of these elements allows. This allows movements of the bridge through a Rotation of this element will be recorded

Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, das die von der Dilatationsfuge abgekehrten Enden der über ein Dilatationselement verbundenen Elemente im Wesentlichen festgelegt sind und sich daher im Wesentlichen stabile Verhältnisse ergebenDue to the features of claim 2, there is the advantage that of the dilatation substantially opposite ends of the elements connected via a dilating element are fixed and therefore result in substantially stable conditions

Um eine einfache Konstruktion zu ermöglichen, ist es vorteilhaft die Merkmale des Anspruches 3 vorzusehen.In order to allow a simple construction, it is advantageous to have the features of Claim 3 provide.

Die Erfindung wird nun anhand der Zeichnung näher erläutert, in der ein Beispiel eines erfindungsgemäßen Rückhaltesystems dargestellt ist. Dabei zeigen:

  • Fig. 1 eine Ansicht eines erfindungsgemäßen Rückhaltesystems,
  • Fig. 2 eine Draufsicht auf ein erfindungsgemäßes Rückhaltesystem in einem Übergangsbereich von einer Brücke zu einem Widerlager,
  • Fig. 3 eine Draufsicht auf eine Verbindung zweier Betonteile,
  • Fig. 4 und 5 eine Ansicht und eine Draufsicht auf ein Gleitlager.
    • The invention will now be explained in more detail with reference to the drawing, in which an example of a restraint system according to the invention is shown. Showing:
  • 1 is a view of a restraint system according to the invention,
  • 2 shows a top view of a restraint system according to the invention in a transition region from a bridge to an abutment,
  • 3 is a plan view of a compound of two concrete parts,
  • 4 and 5 is a view and a plan view of a plain bearing.

    • Bei dem erfindungsgemäßen Rückhaltesystem sind im Bereich einer Dilatationsfuge 30 zwischen einem Brückenteil mit Verkehrsfläche 2 und einem Widerlager samt Verkehrsfläche 3 Elemente 1 aufgestellt. Dabei sind die Elemente 1, z.B. Betonelemente, über ein Zugband 4 (strichliert dargestellt), oder zugfeste Verbindungen miteinander verbunden.In the restraint system according to the invention, in the region of a dilatation joint 30 between a bridge section with traffic area 2 and an abutment including traffic area 3 elements 1 set up. The elements 1, e.g. Concrete elements, via a drawstring 4 (shown in dashed lines), or tensile connections connected to each other.

    In diesem Zugband 4 ist zum Ausgleich von Wärmedehnungen im Bereich der Dilatationsfuge 30 ein Dilatationselement 5 angeordnet, das im wesentlichen durch ein Zylinder-Kolbenelement gebildet ist, dessen durch den Kolben voneinander getrennte Räume über eine Überströmleitung, die einen nur kleinen Querschnitt aufweist, miteinander verbunden sind, sodass Fluid von einem dieser beiden Räume in den anderen überströmen kann, wie dies z.B. bei einer Leitwandkupplung nach der DE 100 26 621 A der Fall ist.In this tension band 4 is to compensate for thermal expansion in the field of Dilatationfuge 30 a dilation 5 arranged, which essentially by a Cylinder-piston element is formed, separated by the piston spaces via an overflow line, which has only a small cross-section, with each other are connected so that fluid from one of these two spaces overflow into the other can, as e.g. in a Leitwandkupplung according to DE 100 26 621 A is the case.

    Dadurch kann sich der Abstand zwischen den beiden über ein Dilatationselement 5 miteinander verbundenen Betonteile 1 langsam ändern, wie dies z.B. bei Wärmedehnungen der Fall ist. Rasche Änderungen des Abstandes zwischen diesen Betonteilen 1, wie sie sich z.B. bei einem Anprall eines Fahrzeuges an dem Rückhaltesystem ergeben würden, sind jedoch nicht möglich, da das Fluid im Zylinder des Dilatationselementes 5 aufgrund des kleinen Querschnittes der Überströmleitung nur langsam von einer Seite des Kolbens auf die andere Seite des Kolbens überströmen kann.As a result, the distance between the two via a dilatation 5 Slowly change interconnected concrete parts 1, e.g. at thermal expansions the case is. Rapid changes in the distance between these concrete parts 1, as they are e.g. would result in a collision of a vehicle to the restraint system, are However, not possible because the fluid in the cylinder of the dilatation 5 due to the small cross section of the overflow only slowly from one side of the piston to the other side of the piston can flow over.

    Im Bereich einer Dilatationsfuge 30 der Brückenkonstruktion, bzw. des Dilatationselementes 5 ist eine Führung 6 (strichliert dargestellt) vorgesehen, die den Spalt zwischen den beiden über das Dilatationselement 5 verbundenen Betonteilen 1 überdeckt und lediglich eine axiale Bewegung dieser Betonelemente 1 gegeneinander ermöglicht.In the area of a dilatation joint 30 of the bridge construction, or of the dilatation element 5 is a guide 6 (shown in phantom), which provides the gap between the two Covered over the dilation element 5 connected concrete parts 1 and only an axial Movement of these concrete elements 1 allows each other.

    Wie aus der Fig. 2 zu ersehen ist, kommt es im Bereich von Kurven aufgrund von Wärmedehnungen nicht nur zu Längenänderungen sondern auch zu Querverschiebungen des Brückenteiles gegenüber dem Widerlager. Die beiden über das Dilatationselement 5 miteinander verbundenen Betonteile 1 sind im Bereich ihrer der Dilatationsfuge 30 näheren Endbereichen über Gleitlager 7 auf der Verkehrsfläche 2 der Brücke bzw. dem Widerlager 3 abgestützt. Die von der Dilatationsfuge 30 abgekehrten Endbereich der Betonteile 1 sind direkt auf den Verkehrsflächen 2, 3 abgestützt. Diese Abstützung ermöglicht ein gemeinsames Verdrehen der beiden Betonteile 1, die über das Dilatationselement 5 und die Führung 6 miteinander verbunden sind. Dadurch können die in Kurvenabschnitten unvermeidlichen Querbewegungen aufgenommen werden.As can be seen from Fig. 2, it comes in the range of curves due to Thermal expansions not only to length changes but also to transverse displacements of the Bridge part opposite the abutment. The two on the dilatation 5 interconnected concrete parts 1 are nearer in the area of their dilatation 30 End areas via slide bearing 7 on the traffic area 2 of the bridge or the abutment. 3 supported. The remote from the dilation joint 30 end portion of the concrete parts 1 are supported directly on the traffic areas 2, 3. This support allows a common Twisting the two concrete parts 1, via the dilation 5 and the guide. 6 connected to each other. This makes the inevitable in curve sections Transverse movements are recorded.

    Zu beiden Seiten der über das Dilatationselement 5 miteinander verbundenen Betonteile 1, schließen Betonteile 1' an. Die Betonteile 1 und 1' sind über eine in der Fig. 3 dargestellte Verbindung miteinander verbunden. Dabei sind Zugbänder 17 in den Betonelementen 1, 1' verankert, die mit Eingriffselementen 18 verbunden sind, die von einem im wesentlichen T-förmigen Kupplungs-Zugglied 19 hintergriffen sind. Dabei ist zwischen den Eingriffselementen 18 und dem Kupplungszugglied 19, bzw. dessen Kopfabschnitten 20, ein Spiel 21 vorgesehen. Dies ermöglicht gemeinsam mit einem ausgleichenden Spalt zwischen den Elementen 1 und 1' eine Winkelstellung der Bauteile 1, 1' zueinander, wie sie in der Fig. 2 dargestellt ist., wobei jedoch eine zugfeste Verbindung gegeben ist. Die Verbindung von Betonteilen 1' miteinander erfolgt ebenfalls über Zugglieder 19 und Eingriffselemente 18.On both sides of the concrete parts 1 interconnected via the dilatation element 5, connect concrete parts 1 '. The concrete parts 1 and 1 'are shown in FIG Connected together. In this case, drawstrings 17 in the concrete elements 1, 1 ' anchored, which are connected to engagement elements 18 which are of a substantially T-shaped Clutch tension member 19 are engaged behind. It is between the Engagement elements 18 and the Kupplungszugglied 19, or its head portions 20, a Game 21 provided. This allows, together with a balancing gap between the elements 1 and 1 'an angular position of the components 1, 1' to each other, as shown in FIG. 2 is shown, but with a high-tensile connection is given. The connection of Concrete parts 1 'together also takes place via tension members 19 and engagement elements 18th

    Bei einer Rückstellung des Brückenteiles gegenüber dem Widerlager kehren die Betonteile 1 wieder in ihre ursprüngliche Lage gegenüber den an diese anschließenden Betonteile 1' zurück, wobei sich die Winkellage W der Betonteile 1 gegenüber den anschließenden Betonteilen 1' wieder auf den ursprünglichen Winkelbetrag einstellt. In a provision of the bridge member relative to the abutment return the concrete parts. 1 back to its original position relative to the adjoining these concrete parts 1 ' back, with the angular position W of the concrete parts 1 with respect to the subsequent Concrete parts 1 'again sets to the original angle amount.

    Die Gleitlager 7 sind, wie aus den Fig. 4 und 5 zu ersehen ist, durch Metallplatten 31, 34 gebildet, die mittels Schrauben 32 mit dem Betonteil 1,1' bzw. der Fahrbahn 2 verbunden sind. Grundsätzlich ist es dabei auch möglich die Metallplatten 31, 34 mit Kunststoff, z.B. Teflon zu beschichten.The sliding bearings 7 are, as can be seen from Figs. 4 and 5, by metal plates 31, 34th formed, which are connected by screws 32 with the concrete part 1,1 'and the roadway 2 are. Basically, it is also possible here the metal plates 31, 34 with plastic, e.g. Teflon coat.

    Dabei ist die Platte 34 in einer Vertiefung 33 der Unterseite des Betonteils 1, 1' angeordnet, wobei auch die Platte 31 in diese Vertiefung 33 hineinragt. Die Begrenzung des Bewegungsweges ergibt sich aus dem Spiel in der Anschlussfugen 35 zwischen den Elementen 1 und 1' und dem zulässigen Drehwinkel der Elemente 1, der sich aufgrund der geometrischen Verhältnisse ermitteln lässt.The plate 34 is arranged in a recess 33 of the underside of the concrete part 1, 1 ', wherein also the plate 31 protrudes into this recess 33. The limitation of Movement path results from the game in the connecting joints 35 between the Elements 1 and 1 'and the permissible angle of rotation of the elements 1, due to the can determine geometric relationships.
