Description

Die Erfindung betrifft eine Abdichteinrichtung zur Abdichtung von Arbeitsfugen und/oder Dehnfugen, insbesondere von Betonierfugen, mit einem Fugenband.The invention relates to a sealing device for sealing of construction joints and / or expansion joints, in particular of concrete joints, with a joint tape.

Betonierfugen bzw. Arbeitsfugen treten insbesondere im Ortbetonbau auf. Arbeitsfugen in Beton- und Stahlbetonkonstruktionen, insbesondere Betonierfugen, die beim Betonieren eines zweiten Betonteils an ein schon vorhandenes erstes Bauteil entstehen, müssen häufig zuverlässig abgedichtet werden. Insbesondere bei wasserundurchlässigen Betonkonstruktionen müssen Betonierfugen bzw. Arbeitsfugen dauerhaft abgedichtet werden.Concreting joints or construction joints occur especially in cast-in-situ construction. Working joints in concrete and reinforced concrete constructions, in particular concreting joints, which arise when concreting a second concrete part to an already existing first component often have to be reliably sealed. Especially in waterproof concrete structures concreting joints or construction joints must be permanently sealed.

Aufgabe der vorliegenden Erfindung ist es, eine Abdichteinrichtung der eingangs genannten Art dahingehend weiterzubilden, dass eine sichere und dauerhafte Abdichtung von Arbeitsfugen ermöglicht wird.Object of the present invention is to develop a sealing device of the type mentioned in that a secure and permanent sealing of construction joints is possible.

Gelöst wird diese Aufgabe durch eine Abdichteinrichtung der eingangs genannten Art, bei der zumindest ein Injektionssystem zur Abdichtung von Bauwerksfugen mit dem Fugenband, insbesondere bleibend und unlösbar, verbunden ist. Da das Fugenband und das Injektionssystem miteinander verbunden werden, können diese gemeinsam installiert werden. Die Abdichtung kann dadurch in zwei Phasen ablaufen. In der ersten Phase erfolgt eine Abdichtung aufgrund einer Barriere, die durch das Fugenband ausgebildet wird. In einer zweiten Phase kann die Abdichtung durch eine Injektion von Verpressmedien mittels des Injektionssystems erfolgen, falls dies erforderlich ist. Somit kann auf das Injektionssystem bei eventuellen Undichtigkeiten später zurückgegriffen werden. Vorzugsweise ist das Injektionssystem mehrfach injizierbar und/oder zementverpressbar. Bei dem Injektionssystem kann es sich um ein handelsübliches, am Markt erhältliches Injektionssystem handeln.This object is achieved by a sealing device of the type mentioned, in which at least one injection system for sealing of building joints with the joint tape, in particular permanent and insoluble, is connected. Since the joint tape and injection system are connected together, they can be installed together. The seal can thus proceed in two phases. In the first phase, a seal occurs due to a barrier formed by the joint tape. In a second phase, sealing may be accomplished by injection of grouting media via the injection system, if necessary. Thus, the injection system can be used later in case of leaks. Preferably, the injection system injectable and / or cement-injectable. The injection system may be a commercially available injection system available on the market.

Besonders bevorzugt ist es, wenn das Fugenband und das zumindest eine Injektionssystem werkseitig verbunden werden. Dadurch können geprüfte und getestete Injektionssysteme verwendet werden, die mit den Fugenbändern verbunden werden.It is particularly preferred if the joint tape and the at least one injection system are connected at the factory. This allows tested and tested injection systems to be used, which are connected to the joint tapes.

Grundsätzlich ist es denkbar, dass das Fugenband und das Injektionssystem abschnittsweise, insbesondere punktuell, miteinander verbunden sind. Eine festere und bessere Verbindung ergibt sich jedoch, wenn das Fugenband und das Injektionssystem kontinuierlich über die gesamte Länge des Injektionssystems, insbesondere vollflächig, miteinander verbunden sind.In principle, it is conceivable that the joint tape and the injection system are connected to each other in sections, in particular at certain points. A firmer and better connection, however, results if the joint tape and the injection system are continuously connected to each other over the entire length of the injection system, in particular over the entire surface.

Das Fugenband und das Injektionssystem können auf jede denkbare Art und Weise miteinander verbunden werden. Besonders bevorzugt ist es jedoch, wenn das Fugenband und das Injektionssystem durch Kleben, Kaltschweißen oder thermische Fügetechnik, insbesondere Schweißen oder Vulkanisieren, verbunden sind. Weiterhin ist es denkbar, dass das Injektionssystem an das Fugenband anextrudiert oder mit dem Fugenband co-extrudiert ist.The joint tape and the injection system can be connected in any conceivable manner. However, it is particularly preferred if the joint tape and the injection system by gluing, cold welding or thermal joining technology, in particular welding or vulcanization, are connected. Furthermore, it is conceivable that the injection system is extruded onto the joint tape or coextruded with the joint tape.

Die eingefügten Injektionssysteme können eine beliebige Geometrie und Beschaffenheit aufweisen. Beispielsweise können sie einen runden oder rechteckigen Querschnitt haben. Vorzugsweise ist das Injektionssystem ein Injektionsschlauch, insbesondere ein Gewebeschlauch, ein Glattmantelschlauch oder ein Flachschlauch, oder ein Injektionsprofil.The inserted injection systems can have any geometry and nature. For example, they may have a round or rectangular cross-section. Preferably, the injection system is an injection tube, in particular a fabric tube, a smooth-walled tube or a flat tube, or an injection profile.

Wenn das Injektionssystem eine wasserquellbare Substanz aufweist, kann das Injektionssystem bei Wasserzutritt quellen und die Fuge abdichten.If the injection system has a water-swellable substance, the injection system can swell when the water enters and seal the joint.

Bei dem Fugenband kann es sich um ein handelsübliches Fugenband handeln.The joint tape may be a commercial joint tape.

Das Fugenband kann aus PVC, einem PVC/Elastomergemisch oder aus einem Elastomer hergestellt sein. Weiterhin kann das Fugenband ein innen liegendes oder ein außen liegendes Fugenband sein.The joint tape can be made of PVC, a PVC / Elastomergemisch or an elastomer. Furthermore, the joint tape may be an inner or an outer joint tape.
