Description

Dichtungsband zur Fugenabdichtung in BetonbauwerkenSealing tape for sealing joints in concrete structures
Beschreibungdescription
Die Erfindung betrifft ein Dichtungsband zum Abdichten von Arbeitsfugen in Betonbau erken mit einem Kernstrang aus elastomerem Material und einer den Kernstrang zumindest partiell umfassenden Außenschicht aus einem unter Wasseraufnahme quellfähigen elastomeren Material.The invention relates to a sealing tape for sealing construction joints in concrete structures with a core strand made of elastomeric material and an outer layer at least partially encompassing the core strand made of an elastomeric material which swells under water absorption.
Quellfähige Fugenbänder werden u. a. verwendet, wenn Bauteile nicht in einem Betonierabschnitt hergestellt werden können. Bei bekannten Dichtungssträngen dieser Art (DE-A 197 02 248) ist die unter Wasseraufnahme quellfahi- ge Außenschicht auf einem Kernstrang aus nicht quellfähigem Material angeordnet . Das Dichtungsband wird in die Arbeitsfuge eines Betonbauwerks eingelegt und hat dort die Aufgabe, die Fuge gegen Wasserdurchtritt abzudichten. Zu diesem Zweck sorgt die unter Wasseraufnahme quellfahi- ge Außenschicht dafür, daß der Wasserdurchtritt durchSwellable joint tapes are u. a. used when components cannot be manufactured in a concreting section. In known sealing strands of this type (DE-A 197 02 248), the outer layer which is capable of swelling under water absorption is arranged on a core strand made of a material which does not swell. The sealing tape is inserted into the construction joint of a concrete structure and has the task of sealing the joint against water penetration. For this purpose, the outer layer, which swells when water is absorbed, ensures that water can pass through
Aufquellen des betreffenden Materials verhindert wird. Um auch auf der ursprünglich festen Fugenbegrenzungsfläche eine ausreichende Abdichtung unter Ausgleich der dort vorhandenen Unebenheiten zu gewährleisten, wird der Pro- filstrang auf dieser Seite mit einem dick aufgetragenen pastösen Kleber, der unter Wasseraufnähme quellfähig sein kann, befestigt. Da die Verformbarkeit der Außenschicht bei Wasseraufnahme zu- und ihre Festigkeit entsprechend abnimmt, kann es an stark aufgequollenen Stellen des Dichtungsbands zu nachteiligen Festigkeitseinbußen kommen. Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, das bekannte Dichtungsband der eingangs angegebenen Art dahingehend zu verbessern, daß über lange Zeit eine zuverlässige Fugenabdichtung gegen Wasserdurchtritt gewährleistet ist.Swelling of the material in question is prevented. In order to ensure adequate sealing even on the originally firm joint boundary surface while compensating for the unevenness present there, the profile strand is fastened on this side with a thickly applied pasty adhesive that can swell under water. Since the deformability of the outer layer increases when water is absorbed and its strength decreases accordingly, disadvantageous losses in strength can occur at swollen parts of the sealing tape. Proceeding from this, the invention has for its object to improve the known sealing tape of the type mentioned in such a way that a reliable joint seal against water penetration is guaranteed for a long time.
Zur Lösung dieser Aufgabe wird die in Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhaf- te Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Advantageous refinements and developments of the invention result from the dependent claims.
Die erfindungsgemäße Lösung geht von der Erkenntnis aus, daß der Kernstrang ohne spürbare Einbuße an Formstabili- tat und Festigkeit wesentlich zur Langzeitabdichtung beitragen kann, wenn er ebenfalls in einem bestimmten Maße unter Wasseraufnahme quellfähig ist. Vorteilhafterweise beträgt die Wasseraufnahme- und/oder Quellfähigkeit des Kernstrangs weniger als 20 %, vorzugsweise 5 bis 10 % derjenigen der Außenschicht.The solution according to the invention is based on the knowledge that the core strand can make a significant contribution to long-term sealing without a noticeable loss in shape stability and strength if it is also swellable to a certain extent with water absorption. The water absorption and / or swelling capacity of the core strand is advantageously less than 20%, preferably 5 to 10%, of that of the outer layer.
Um sicherzustellen, daß sich der Kernstrang erst dann ausdehnt, wenn die Außenschicht aufgequollen ist, wird gemäß einer bevorzugten Ausgestaltung der Erfindung vor- geschlagen, daß die Außenschicht den Kernstrang vollständig umschließt, so daß der Kernstrang nur über die aufgequollene Außenschicht mit Wasser in Berührung kommen kann.In order to ensure that the core strand does not expand until the outer layer has swollen, it is proposed according to a preferred embodiment of the invention that the outer layer completely surrounds the core strand, so that the core strand comes into contact with water only via the swollen outer layer can.
Für den Fall, daß das Dichtungsband am Fertigbetonteil angeklebt wird, ist es von Vorteil, wenn der Kernstrang ein Hohlprofil aufweist. Wird das Dichtungsband jedoch auf dem Festbetonteil aufgenagelt, so ist es von Vorteil, wenn der Kernstrang als Massivstrang ausgebildet ist.In the event that the sealing tape is glued to the prefabricated concrete part, it is advantageous if the core strand has a hollow profile. However, if the sealing tape is nailed onto the reinforced concrete part, it is advantageous if the core strand is designed as a solid strand.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß der Kernstrang und damit auch das Dichtungsband einen im wesentlichen trapezförmigen Umriß aufweist. Die Außenschicht weist hierbei zweckmäßig eine über den gesamten Umfang des Dichtungsbands konstante Wandstärke auf . Dabei hat es sich als vorteilhaft erwiesen, wenn der Kernstrang und die Außenschicht im Koextrusionsverfahren stoffschlüssig miteinander verbunden werden.A preferred embodiment of the invention provides that the core strand and thus also the sealing tape has an essentially trapezoidal outline. The outer layer expediently has a constant wall thickness over the entire circumference of the sealing tape. It has proven to be advantageous if the core strand and the outer layer are integrally bonded to one another in the coextrusion process.
Im folgenden wird die Erfindung anhand der in der Zeich- nung in schematischer Weise dargestellten Ausführungsbei- spiele näher erläutert. Es zeigenThe invention is explained in more detail below on the basis of the exemplary embodiments shown schematically in the drawing. Show it

Kernstrang ein Hohlprofil aufweist,Core strand has a hollow profile,
Fig. 2 eine Darstellung entsprechend Fig. 1 unter Verwendung eines Dichtungsbands mit massivem Kernstrang.Fig. 2 is a representation corresponding to FIG. 1 using a sealing tape with a solid core strand.
Die Fig. 1 und 2 zeigen eine Bodenplatte 10 und eine Wand 12 jeweils aus Beton, die in zwei aufeinanderfolgenden Betonierabschnitten betoniert wurden, so daß sich zwi- sehen ihnen eine Arbeitsfuge 14 ausgebildet hat. Die Arbeitsfuge 14 ist durch ein Dichtungsband 16 abgedichtet. Das Dichtungsband 16 weist im Falle der Fig. 1 einen im wesentlichen trapezförmigen und im Falle der Fig. 2 einen rechteckigen Querschnitt auf. Es enthält einen Kernstrang 20 aus kautschukelastischem Material, der im Falle der Fig. 1 mehrere parallel zueinander ausgerichtete Hohlkanäle 22 aufweist, während er im Falle der Fig. 2 massiv ausgebildet ist. Der Kernstrang 20 ist von einer Außenschicht 28 umschlossen, die aus einem unter Wasseraufnahme quellfähigen elastomeren Material besteht. Auch der Kernstrang 20 ist unter Wasseraufnahme quellfähig, wobei die Wasseraufnähme- und/oder Quellfähigkeit des Kernstrangs weniger als 20 %, vorzugsweise 5 bis 10 % derjenigen der Außenschicht 28 beträgt.1 and 2 show a base plate 10 and a wall 12 each made of concrete, which were concreted in two successive concreting sections, so that a construction joint 14 has formed between them. The construction joint 14 is sealed by a sealing tape 16. The sealing tape 16 has an essentially trapezoidal cross section in the case of FIG. 1 and a rectangular cross section in the case of FIG. 2. It contains a core strand 20 made of rubber-elastic material which, in the case of FIG. 1, has a plurality of hollow channels 22 aligned parallel to one another, while in the case of FIG. 2 it is solid. The core strand 20 is enclosed by an outer layer 28, which consists of an elastomeric material which is capable of swelling under water absorption. The core strand 20 is also swellable with the absorption of water, the water absorption and / or swelling ability of the core strand being less than 20%, preferably 5 to 10%, of that of the outer layer 28.
In einem ersten Betonierabschnitt wird Frischbeton zur Herstellung der Bodenplatte 10 in eine entsprechende Schalung gegossen und zum Aushärten gebracht. Sodann wird das Dichtungsband 16 mit seiner Basisfläche 30 mit Hilfe eines pastösen Klebers 32 auf die unebene Fugenbegren- zungsfläche 34 der Bodenplatte 10 aufgeklebt. Die Unebenheiten in der Fugenbegrenzungsfläche 34 werden durch den Kleber 32 ausgeglichen. In einem zweiten Betonierabschnitt wird die Wand 12 betoniert und dabei das Dichtungsband 16 mit Flüssigbeton umgössen, so daß sich eine zweite Fugenbegrenzungsfläche 36 bildet.In a first concreting section, fresh concrete is poured into an appropriate formwork for the production of the floor slab 10 and brought to hardening. The sealing tape 16 is then glued with its base surface 30 onto the uneven joint boundary surface 34 of the base plate 10 with the aid of a pasty adhesive 32. The unevenness in the joint boundary surface 34 is compensated for by the adhesive 32. In a second concreting section, the wall 12 is concreted and the sealing tape 16 is poured with liquid concrete, so that a second joint boundary surface 36 is formed.
Die unter Wasseraufnahme quellende Außenschicht 28 sorgt dafür, daß das Dichtungsband 18 bei Wasserzutritt nach allen Richtungen aufquellen kann, so daß die Fuge 14 ge- gen Wasserdurchtritt verschlossen wird. Die Langzeitabdichtung wird dadurch gewährleistet, daß auch der Kernstrang 20 durch die aufgequollene Außenschicht hindurch mit Wasser in Berührung kommen und dabei weitgehend ohne Festigkeitsverlust quellen kann.The outer layer 28, which swells when water is absorbed, ensures that the sealing tape 18 can swell in all directions when water enters, so that the joint 14 is sealed against water penetration. The long-term sealing is ensured by the fact that the Core strand 20 can come into contact with water through the swollen outer layer and can swell largely without loss of strength.
Zusammenfassend ist folgendes festzuhalten: Die Erfindung bezieht sich auf ein Dichtungsband zur Fugenabdichtung in Betonbauwerken. Das Dichtungsband 18 weist einen Kernstrang 20 aus elastomerem Material und eine den Kernstrang 20 zumindest partiell umfassende Außenschicht 28 aus einem unter Wasseraufnähme quellfähigen elastomerem Material auf . Um eine zuverlässige Langzeitabdichtung zu gewährleisten, ist auch der Kernstrang 20 unter Wasseraufnahme quellfähig, wobei die Wasseraufnähme- und/oder Quellfähigkeit des Kernstrangs 20 weniger als 20 % derjenigen der Außenschicht 28 beträgt. In summary, the following can be stated: The invention relates to a sealing tape for sealing joints in concrete structures. The sealing strip 18 has a core strand 20 made of elastomeric material and an outer layer 28 at least partially surrounding the core strand 20 made of an elastomeric material which is swellable by absorbing water. In order to ensure reliable long-term sealing, the core strand 20 is also swellable while absorbing water, the water absorption and / or swellability of the core strand 20 being less than 20% of that of the outer layer 28.
