Abstract

The invention concerns a device for sealing joints (16) between concrete components, e.g. the joints between assembled sewer pipes (10, 11). The invention calls for instance for annular sealing strip (14) made of a prepolymer of, for example polyurethane. After assembling the pipes, the polymerization process is initiated, for instance by means of a heating wire located in the sealing ring (14), thus causing the prepolymer to foam and the joint (16) to be sealed off on completion of the polymerization process.

Description

Die vorliegende Erfindung betrifft eine Abdichtvorrichtung für Fugen zwischen Bauteilen sowie ein Verfahren zur Abdichtung von Fugen zwischen Bauteilen. Nach dem Stand der Technik erfolgt die Fugenabdichtung bei Bauwerken zwischen einzelnen Betonbauteilen wie z. B. Rohren, Schächten oder anderen Bauteilen im Kanalbau, bei Tunnelbauwerken, im Brückenbau oder bei Fertigbauten mit Hilfe von fertigen Dichtungen aus gummiähnlichen bzw. kautschukartigen Materialien. Diese Dichtungen werden gegebenenfalls der Form der Bauteile zwischen denen abgedichtet werden soll angepaßt. Es kann auch eine funktionelle Anpassung der Dichtungen vorgesehen sein, so werden z. B. für die Abdichtung der Verbindungsfugen von Betonrohren im Kanalbau sogenannte Rollringe oder auch Lippendichtungen verwendet. Der Nachteil der bekannten herstellerseitig angepaßten Dichtungen besteht darin, daß häufig nach der Montage der zu verbindenden Bauteile die Dichtung einen schlechten Sitz hat und daher keine effektive Abdichtung gewährleistet. Häufig wird die unzureichende Abdichtung nicht oder nicht sofort festgestellt. Aber auch wenn diese festgestellt wird, ist in der Regel eine Korrektur nicht oder nur mit erheblichem Aufwand möglich.The present invention relates to a sealing device for joints between components and a method for Sealing joints between components. According to the state of the Technology is used to seal joints in buildings between individual concrete components such. B. pipes, shafts or other components in sewer construction, in tunnel structures, in Bridge construction or in prefabricated buildings with the help of finished Seals made of rubber-like or rubber-like Materials. These seals may be of shape the components between which should be sealed customized. It can also be a functional adjustment of the Seals are provided so. B. for the Sealing the joints of concrete pipes in sewer construction so-called rolling rings or lip seals are used. The disadvantage of the known manufacturer adapted Seals is that often after assembly of the connecting components the seal has a poor fit and therefore no effective sealing is guaranteed. Often insufficient sealing will not or not immediately detected. But even if this is found, is in usually no correction or only with considerable Effort possible.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Abdichtvorrichtung für Fugen zwischen Bauteilen der obengenannten Art sowie ein Verfahren zur Abdichtung von Fugen zwischen derartigen Bauteilen zu schaffen, die (das) eine einwandfreie Abdichtung der Fuge gewährleistet.The object of the present invention is therefore a sealing device for joints between components of the Above type and a method for sealing Creating gaps between such components that a perfect seal of the joint is guaranteed.

Die Lösung der Aufgabe liefert eine erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 sowie ein erfindungsgemäßes Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 7. Nach der erfindungsgemäßen Lösung wird ein Dichtungsstreifen, Dichtungsring etc., je nach Anwendungszweck, aus einem Präpolymeren in die abzudichtende Fuge zwischen den jeweiligen Bauteilen, also z. B. in die Verbindungsfuge zwischen zwei Kanalrohren gebracht und anschließend wird durch Zufuhr einer definierten berechneten Wärmemenge der Polymerisationsvorgang in Gang gesetzt, der zu einer definierten Volumenzunahme der Polymerdichtung führt, die nach Beendigung des Polymerisationsvorgangs die Fuge vollständig abdichtet.An object according to the invention provides the solution to the problem Device with the characterizing features of the claim 1 and an inventive method with the characterizing features of claim 7. After the solution according to the invention is a sealing strip, Sealing ring etc., depending on the application, from one Prepolymers in the joint to be sealed between the respective components, e.g. B. in the joint  brought between two sewer pipes and then by supplying a defined calculated amount of heat Polymerization process started, which leads to a leads to a defined increase in volume of the polymer seal after the polymerization process, the joint completely seals.

Als Präpolymer gemäß der Erfindung können beispielsweise solche auf Polyurethan-, Acrylharz-, oder Epoxidharzbasis oder Präpolymere mit ähnlichen Eigenschaften dienen. Das Einleiten des Polymerisationsvorgangs durch Wärme erscheint im Rahmen der Erfindung als vorteilhaft, es sind aber auch andere bekannte Verfahren zum Start der Polymerisation, z. B. durch Bestrahlung, möglich. Wenn man den Polymerisationsvorgang durch Wärme einleiten will, so kann dies gemäß einer vorteilhaften Ausführungsform der Erfindung dadurch geschehen, daß man in dem Dichtungsstreifen, Dichtungsring etc. einen Heizdraht verlegt, dessen Enden aus dem Dichtungsmaterial herausgeführt sind und an eine Stromquelle angeschlossen werden. Durch Wahl der Stromstärke, Spannung und der Zeitdauer der Erwärmung des Heizdrahts kann man dann eine definierte Wärmemenge zuführen.As a prepolymer according to the invention, for example those based on polyurethane, acrylic resin or epoxy resin or prepolymers with similar properties. The Initiation of the polymerization process by heat appears in the context of the invention as advantageous, but also other known methods of starting the polymerization, e.g. B. by radiation, possible. If you do that Wants to initiate the polymerization process by heat this according to an advantageous embodiment of the invention by doing that in the weather strip, Sealing ring etc. laid a heating wire, the ends of which the sealing material are led out and to a Power source can be connected. By choosing the Current, voltage and the duration of the heating of the Heating wire can then be a defined amount of heat respectively.

Eine andere vorteilhafte Möglichkeit besteht, z. B. wenn es sich um eine Abdichtung der Fuge zwischen zwei Kanalrohren mittels einer ringförmigen Dichtung handelt, darin, daß man eine Leiterschleife in dem Ring aus dem Präpolymeren verlegt, deren Enden kurzgeschlossen werden. Man kann dann in das Kanalrohr in die Ebene der Ringdichtung aus dem Präpolymeren und somit in das Zentrum der kurzgeschlossenen Leiterschleife eine Induktionsspule einbringen, durch die man einen Wechselstrom fließen läßt. Dadurch wird in der kurzgeschlossenen Leiterschleife als Sekundärkreis Wärme erzeugt, die den Polymerisationsvorgang einleitet. Dieser führt wiederum zu einer irreversiblen Volumenvergrößerung des Polymeren, das dann die Ringfuge abdichtet.Another advantageous possibility is e.g. B. if it is to seal the joint between two sewer pipes acts by means of an annular seal in that a conductor loop in the ring made of the prepolymer misplaced, the ends of which are short-circuited. You can then into the sewer pipe in the level of the ring seal from the Prepolymers and thus in the center of the short-circuited Insert an induction coil through the conductor loop an alternating current is allowed to flow. This will in the short-circuited conductor loop as a secondary circuit heat generated, which initiates the polymerization process. This in turn leads to an irreversible increase in volume of the polymer, which then seals the ring joint.

Im folgenden wird die vorliegende Erfindung anhand eines Ausführungsbeispiels unter Bezugnahme auf die beiliegenden Zeichnungen näher beschrieben. Dabei zeigenIn the following, the present invention is based on a Embodiment with reference to the accompanying Drawings described in more detail. Show

Fig. 1 einen Längsschnitt durch zwei Betonrohre im Fugenbereich; Fig. 1 shows a longitudinal section through two concrete pipes in the joint area;

Fig. 2 einen Längsschnitt gemäß Fig. 1 mit aufgeschäumtem Dichtungsring; FIG. 2 shows a longitudinal section according to FIG. 1 with a foamed sealing ring;

Fig. 3 einen Querschnitt entlang der Linie III-III von Fig. 1. Fig. 3 is a cross section along the line III-III of Fig. 1,.

Die Darstellung gemäß Fig. 1 zeigt zwei Kanalisationsrohre 10, 11 aus Beton, die in axialer Verlängerung miteinander verbunden sind. Die Rohre 10, 11 werden im Verbindungsbereich ineinander geschoben, wobei an dem einen Rohr 10 durch einen Absatz ein Endbereich 12 mit geringerer Wandstärke ausgebildet ist, der von einem durch einen innenseitigen Absatz gebildeten verjüngten Endbereich 13 des anderen Rohrs 11 überlappt wird. Die zwischen dem stirnseitigen Ende des Rohrs 11 und dem Absatz 17 des Rohrs 10 verbleibende Fuge 16 nimmt eine Ringdichtung 14 aus einem geeigneten Präpolymeren, z. B. auf Polyurethanbasis auf, wobei die Ringdichtung 14 wie aus Fig. 1 ersichtlich ist, die Fuge 16 nicht vollständig ausfüllt.The illustration in Fig. 1 shows two sewer pipes 10, 11 made of concrete, which are connected in the axial extension of each other. The tubes 10 , 11 are pushed into one another in the connection area, an end area 12 having a smaller wall thickness being formed on one tube 10 by a shoulder, which is overlapped by a tapered end area 13 of the other tube 11 formed by an inner shoulder. The gap 16 remaining between the front end of the tube 11 and the shoulder 17 of the tube 10 takes an annular seal 14 made of a suitable prepolymer, eg. B. based on polyurethane, wherein the ring seal 14 as shown in Fig. 1, the joint 16 does not completely fill.

Wie man aus Fig. 3 erkennen kann, befindet sich in der Ringdichtung 14 eingeschlossen ein Heizdraht 15, dessen Enden aus der Ringdichtung herausgeführt sind. Diese beiden Enden des Heizdrahts 15 können an eine Stromwelle angeschlossen werden, so daß der Heizdraht sich erwärmt und in der Ringdichtung aus dem Präpolymeren einen Polymerisationsvorgang auslöst. Das Präpolymere schäumt dann auf, so daß sich das Volumen des Präpolymeren in vorher berechnetem Umfang erweitert und die Ringdichtung füllt nach Ablauf des Polymerisationsvorgangs die Fuge 16 vollständig aus (siehe Fig. 2).As can be seen from FIG. 3, a heating wire 15 is enclosed in the ring seal 14 , the ends of which are led out of the ring seal. These two ends of the heating wire 15 can be connected to a current wave, so that the heating wire heats up and triggers a polymerization process in the ring seal from the prepolymer. The prepolymer then foams, so that the volume of the prepolymer increases to a previously calculated extent and the ring seal completely fills the joint 16 after the polymerization process (see FIG. 2).
