Description

Die vorliegende Erfindung betrifft ein Fugenband, insbesondere innenliegendes Arbeits- oder Dehnungsfugenband, zum Abdichten von Fugen im Betonbau, bestehend aus einem extrudierten Profilstrang aus Kunststoff oder Kautschuk mit mindestens zwei in den Beton einzubettenden Seitenbahnen, wobei der Profilstrang am Längsrand mindestens einer der Seitenbahnen homogen, materialeinheitlich mit einem in Profillängsrichtung verlaufenden Randstreifen verbunden ist, wobei der Randstreifen in Profillängsrichtung voneinander beabstandete Bindedrahthalterungen aufweist.The present invention relates to a joint tape, in particular internal working or expansion joint tape, for sealing joints in concrete construction, consisting of an extruded profile strand made of plastic or rubber with at least two side panels to be embedded in the concrete, the profile strand being homogeneous on the longitudinal edge of at least one of the side panels, materially connected to an edge strip running in the longitudinal direction of the profile, the edge strip having tie wire holders spaced apart from one another in the longitudinal direction of the profile.

Derartige Fugenbänder dienen zum elastischen Abdichten von wasserdichten Beton-Bauwerken im Bereich von zwischen jeweils zwei benachbarten Beton-Bauteilen gebildeten Dehnungs-, Bewegungs- bzw. Arbeitsfugen. Hierbei wird jeweils eine randliche Seitenbahn in eines der Beton-Bauteile eingebettet. Die Seitenbahn besitzt dabei eine derartige Profilierung, daß ein möglichst langer Wasserumlaufweg gebildet wird, wodurch eine Abdichtung nach dem sog. Labyrinthprinzip erreicht wird. Um in jedem Fall den maximal möglichen Wasserumlaufweg zu gewährleisten, ist es notwendig, das Fugenband vor dem Betonieren so an der Verschalung zu befestigen, daß sich die Seitenbahnen möglichst senkrecht zu der Fuge in den Beton hinein erstrecken. Es muß folglich in jedem Fall verhindert werden, daß sich die Seitenbahnen durch ihr Eigengewicht oder durch herabfallenden Beton verbiegen und in unkontrollierter Lage eingebettet werden. Zu diesem Zweck ist es bekannt, an verdickten Randwulsten der Seitenbahnen Klammern klemmend bzw. kraft- und/oder formschlüssig zu befestigen. An diesen Klammern, die in Abständen von etwa 30 bis 50 cm voneinander angeordnet werden, können Bindedrähte, sog. Rödeldrähte, befestigt werden, mit denen dann die Seitenbahnen in ihrer Soll-Lage durch schräges Abspannen fixiert werden können. Die Montage ist jedoch sehr aufwendig, da die Klammern einzeln beispielsweise mittels einer Zange angeklemmt werden müssen, bevor das Abspannen mittels Draht erfolgen kann.Such joint tapes are used for the elastic sealing of watertight concrete structures in the area of expansion, movement or construction joints formed between two adjacent concrete components. Here, an edge side web is embedded in one of the concrete components. The side web has such a profile that the longest possible water circulation path is formed, whereby a seal is achieved according to the so-called labyrinth principle. In order to ensure the maximum possible water circulation path in any case, it is necessary to close the joint tape on the formwork before concreting fasten that the side panels extend into the concrete as perpendicular to the joint as possible. It must therefore be prevented in any case that the side panels bend due to their own weight or due to falling concrete and be embedded in an uncontrolled position. For this purpose, it is known to fasten clamps to thickened edge beads of the side webs in a clamped or non-positive and / or positive manner. These clips, which are arranged at intervals of about 30 to 50 cm from each other, can be used to attach binding wires, so-called. Rope wires, with which the side tracks can then be fixed in their desired position by angled bracing. However, assembly is very complex since the clamps have to be clamped individually, for example using pliers, before they can be tensioned using wire.

Ein Fugenband der eingangs genannten, gattungsgemäßen Art ist aus der GB-A-1 016 106 bekannt. Dieses Fugenband ("water-stop") besteht ebenfalls aus einem Profilstrang mit zwei in Beton einzubettenden Seitenbahnen, wobei hier jede Seitenbahn mit einem Randstreifen verbunden ist, an dem als Bindedrahthalterungen Haken über Hohlniete befestigt sind. Die Randstreifen sind hier aber jeweils von einem Teil der Seitenbahn (web) bzw. des Profilstranges gebildet, was aber bedeutet, daß die Randstreifen aus demselben, üblicherweise möglichst weichen, flexiblen und elastischen Material wie der gesamte Profilstrang bestehen. Dies führt aber nachteiligerweise zu der Gefahr, daß die Haken beim Verspannen mit Binde- bzw. Rödeldraht ausreißen können. Demgegenüber würde die Verwendung eines härteren Materials zu einer Verschlechterung der Dichteigenschaften und/oder der Dehnungseigenschaften des in den Beton eingebetteten Fugenbandes führen.A joint tape of the aforementioned generic type is known from GB-A-1 016 106. This joint tape ("water-stop") also consists of a profile strand with two side webs to be embedded in concrete, each side web being connected here with an edge strip to which hooks are fastened via tubular rivets as binding wire holders. The edge strips here are each formed by part of the side web (web) or the profile strand, which means that the edge strips consist of the same, usually as soft, flexible and elastic material as the entire profile strand. However, this disadvantageously leads to the risk that the hooks can tear out when bracing with binding wire or string wire. In contrast, the use of a harder material would lead to a deterioration in the sealing properties and / or the expansion properties of the joint tape embedded in the concrete.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das bekannte Fugenband so zu verbessern, daß es einerseits optimale Funktionseigenschaften, d.h. Dicht- und Dehnungseigenschaften, sowie andererseits auch eine hohe Haltbarkeit im Bereich der Bindedrahthalterungen aufweist, wobei zudem auch eine rationelle und preiswerte Herstellung möglich sein soll. Hierzu soll auch ein bevorzugtes Herstellungsverfahren angegeben werden.The present invention has for its object to improve the known joint tape so that on the one hand it has optimal functional properties, i.e. Sealing and stretching properties, and on the other hand also has a high durability in the area of the binding wire holders, and in addition, rational and inexpensive production should also be possible. For this purpose, a preferred manufacturing process should also be specified.

Erfindungsgemäß wird dies mit einem Fugenband gemäß dem Patentanspruch 1 dadurch erreicht, daß der Profilstrang und der Randstreifen aus zwei verschiedenen Materialien bestehen, und zwar der Profilstrang aus einem weichen, elastischen Material und der Randstreifen aus einem im Vergleich zum Profilstrang härteren, zäheren Material.According to the invention this is achieved with a joint tape according to claim 1 in that the profile strand and the edge strip consist of two different materials, namely the profile strand made of a soft, elastic material and the edge strip made of a harder, tougher material compared to the profile strand.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen 2 bis 7 enthalten.Advantageous developments of the invention are contained in the dependent claims 2 to 7.

Ein bevorzugtes Herstellungsverfahren ist im Patentanspruch 8 angegeben. Hierdurch wird erreicht, daß trotz der Verwendung zweier verschiedener Materialien das erfindungsgemäße Fugenband in einem Extrusionsgang schnell und preiswert hergestellt werden kann.A preferred manufacturing method is specified in claim 8. This ensures that, despite the use of two different materials, the joint tape according to the invention can be produced quickly and inexpensively in one extrusion process.

Vorzugsweise besitzt jede Seitenbahn einen derartig angeformten Randstreifen. Dabei ist es besonders zweckmäßig, wenn die Bindedrahthalterungen ösenartig als Durchgangslöcher des Randstreifens ausgebildet sind. Die erforderlichen Befestigungen bzw. Abspannungen können in einfacher Weise durchgeführt werden, indem Bindedraht über die Durchgangslöcher an dem oder den Randstreifen befestigt wird.Each side web preferably has an edge strip formed in this way. It is particularly expedient if the binding wire holders are designed as eyelets as through holes in the edge strip. The required fastenings or bracing can be carried out in a simple manner by fastening binding wire to the edge strip or strips via the through holes.

Indem die Randstreifen erfindungsgemäß aus einem gegenüber dem Material des Profilstranges härteren bzw. zäheren Material bestehen, wird vorteilhafterweise ein Ausreißen der ösenartigen Durchgangslöcher verhindert. So können die Randstreifen insbesondere aus Hart-PVC oder einem anderen Hart-Kunststoff bestehen, während der Profilstrang bevorzugt aus Weich-PVC besteht.In that the edge strips according to the invention consist of a material that is harder or tougher than the material of the profile strand, the tearing-out through holes are advantageously prevented from being torn out. The edge strips can in particular consist of hard PVC or another hard plastic, while the profile strand preferably consists of soft PVC.

Anhand eines in der Zeichnung dargestellten, bevorzugten Ausführungsbeispiels soll im folgenden die Erfindung näher erläutert werden. Dabei zeigt die einzige Figur einen Querschnitt durch ein erfindungsgemäßes Fugenband.The invention will be explained in more detail below with reference to a preferred exemplary embodiment shown in the drawing. The single figure shows a cross section through a joint tape according to the invention.

Ein erfindungsgemäßes Fugenband 2 besteht aus einem extrudierten Profilstrang 4 aus Kunststoff oder aus Kautschuk (Gummi). Bei dem dargestellten Fugenband 2 handelt es sich um ein sog. Dehnungsfugenband mit einem im Bereich der betonfreien Fuge anzuordnenden Mittelschlauch 6, von dem aus sich in entgegengesetzte Richtungen zwei Seitenbahnen 8 erstrecken. Der Mittelschlauch 6 kann - wie dargestellt - eine Nagellasche 10 zum Befestigen des Profilstranges 4 an einer nicht dargestellten Holzverschalung aufweisen. Darüber hinaus läßt sich die Erfindung jedoch auch bei sog. Arbeitsfugenbändern ohne Mittelschlauch verwirklichen.A joint tape 2 according to the invention consists of an extruded profile strand 4 made of plastic or of rubber (rubber). The joint tape 2 shown is a so-called expansion joint tape with a central hose 6 to be arranged in the area of the concrete-free joint, from which two side webs 8 extend in opposite directions. The center tube 6 can - as shown - have a nail tab 10 for attaching the profile strand 4 to a wooden casing, not shown. In addition, however, the invention can also be implemented in so-called construction joint tapes without a central hose.

Jede Seitenbahn 8 besitzt in ihrem Flächenbereich mindestens eine Ankerrippe 12 sowie an ihrem freien Längsrand 14 einen Randwulst 16. Zwischen der Ankerrippe 12 und dem Randwulst 16 ist üblicherweise eine Riffelung oder Rippung 18 gebildet. Der Bereich zwischen den Ankerrippen 12 einschließlich des Mittelschlauches 6 bildet eine Dehnungszone 20, und der sich von der Ankerrippe 20 nach außen erstrekkende Bereich jeder Seitenbahn 8 bildet eine Dichtungszone 22, wobei die hier vorgesehene Profilierung zu einer Verlängerung des Wasserumlaufweges und damit zu einer Dichtwirkung nach dem Labyrinthprinzip dient. Darüber hinaus wird durch die Profilierung auch eine formschlüssige Verbindung zwischen dem Fugenband und dem das Fugenband im Bereich der Seitenbahnen einschließenden Beton gebildet.Each side web 8 has at least one anchor rib 12 in its area and an edge bead 16 on its free longitudinal edge 14. A corrugation or ribbing 18 is usually formed between the anchor rib 12 and the edge bead 16. The area between the anchor ribs 12, including the middle tube 6, forms an expansion zone 20, and the area that extends outward from the anchor rib 20 The area of each side web 8 forms a sealing zone 22, the profiling provided here serving to extend the water circulation path and thus to provide a sealing effect based on the labyrinth principle. In addition, the profiling also forms a positive connection between the joint tape and the concrete enclosing the joint tape in the region of the side panels.

Der Profilstrang 4 ist am Längsrand 14 mindestens einer der Seitenbahnen 8 stoffschlüssig mit einem in Profillängsrichtung verlaufenden Randstreifen 24 verbunden. Dieser Randstreifen 24 weist in Profillängsrichtung voneinander beabstandete Bindedrahthalterungen 26 auf. Vorzugsweise besitzt der Profilstrang 4 an seinen beiden Längsrändern 14 jeweils einen Randstreifen 24. Die Bindedrahthalterungen 26 sind in der dargestellten, besonders vorteilhaften Ausführung der Erfindung als besonders einfach herzustellende Durchgangslöcher 28 des jeweiligen Randstreifens 24 ausgebildet, wobei durch diese Durchgangslöcher 28 praktisch Befestigungsösen gebildet sind, durch die - wie in der Zeichnung angedeutet - ein Bindedraht 30, d.h. ein sog. Rödeldraht, hindurchgezogen und hiermit durch schräges Abspannen die jeweilige Seitenbahn 8 in ihrer Soll-Lage ausgerichtet fixiert werden kann.The profile strand 4 is integrally connected on the longitudinal edge 14 of at least one of the side webs 8 to an edge strip 24 running in the longitudinal direction of the profile. This edge strip 24 has binding wire holders 26 spaced apart from one another in the longitudinal direction of the profile. The profile strand 4 preferably has an edge strip 24 on each of its two longitudinal edges 14. In the illustrated, particularly advantageous embodiment of the invention, the binding wire holders 26 are designed as through holes 28 of the respective edge strip 24 which are particularly simple to produce, with through holes 28 practically forming fastening eyelets, through - as indicated in the drawing - a binding wire 30, ie a so-called Rödeldraht, pulled through and hereby the respective side web 8 can be fixed aligned in its target position by oblique bracing.

Wie dargestellt, sind die Randstreifen 24 vorzugsweise in der Ebene des Profilstranges 4 liegend angeordnet. Die Durchgangslöcher 28 sind erfindungsgemäß um jeweils 5 bis 15 cm, vorzugsweise etwa 10 cm, in Profillängsrichtung voneinander beabstandet, was die Montage des erfindungsgemäßen Fugenbandes insofern begünstigt, als hierdurch sehr viele Möglichkeiten zum Befestigen des Bindedrahtes 30 zur Verfügung stehen.As shown, the edge strips 24 are preferably arranged lying in the plane of the profile strand 4. The through holes 28 are spaced from each other by 5 to 15 cm, preferably about 10 cm, in the longitudinal direction of the profile, which favors the assembly of the joint tape according to the invention in that there are many possibilities for fastening the binding wire 30.

Aufgrund von durch das beschriebene Abspannen über den Bindedraht 30 auftretenden, sehr hohen Zugkräften ist die Verbindung zwischen den Randstreifen 24 und dem Profilstrang 4 ein erfindungswesentlicher Aspekt.Because of the very high tensile forces that occur due to the described tensioning over the binding wire 30, the connection between the edge strips 24 and the profile strand 4 is an aspect essential to the invention.

Der Profilstrang 4 ist erfindungsgemäß mit dem jeweiligen Randstreifen 24 homogen, d.h. materialeinheitlich verbunden. Insbesondere besteht der Profilstrang 4 hierbei aus einem Weich-PVC, während die Randstreifen 24 aus Hart-PVC bestehen. Diese Materialien lassen sich homogen und damit außerordentlich fest miteinander verbinden, so daß hohe Zugkräfte aufgenommen werden können, ohne daß der Randstreifen von dem Profilstrang 4 abgerissen werden könnte.According to the invention, the profile strand 4 is homogeneous with the respective edge strip 24, i.e. materially connected. In particular, the profile strand 4 consists of a soft PVC, while the edge strips 24 consist of hard PVC. These materials can be homogeneously and therefore extremely firmly bonded to one another, so that high tensile forces can be absorbed without the edge strip being able to be torn off from the profile strand 4.

Erfindungsgemäß werden in einem Arbeitsgang einerseits der Profilstrang 4 aus Weich-PVC und andererseits die Randstreifen 24 aus Hart-PVC zunächst gesondert für sich, jedoch vorzugsweise in einer gemeinsamen Vorrichtung, geformt und noch innerhalb eines Extruder- bzw. Spritzkopfes in noch plastischem Zustand zusammengeführt und so homogen verbunden. Das weiche Material des Profilstranges 4 gewährleistet dabei die gewünschte Elastizität, und das härtere Material der Randstreifen 24 verhindert ein Ausreißen der Durchgangslöcher 28 beim Verspannen mit dem Bindedraht 30.According to the invention, on the one hand the profile strand 4 made of soft PVC and on the other hand the edge strips 24 made of hard PVC are initially formed separately for themselves, but preferably in a common device, and are still brought together in a still plastic state within an extruder or injection head so homogeneously connected. The soft material of the profile strand 4 ensures the desired elasticity, and the harder material of the edge strips 24 prevents the through holes 28 from being torn out when braced with the binding wire 30.

Die Erfindung ist nicht auf das dargestellte und beschriebene Ausführungsbeispiel beschränkt, sondern umfaßt auch alle im Sinne der Erfindung gemäß den Ansprüchen 1-8 gleichwirkenden Ausführungen. Insbesondere kann die Erfindung auch bei solchen Profilen angewendet werden, die mehr als nur zwei in den Beton einzubettende Seitenbahnen aufweisen, wie dies beispielsweise bei sogenannten außenliegenden Fugenbändern der Fall ist.The invention is not limited to the exemplary embodiment shown and described, but also includes all embodiments having the same effect in the sense of the invention according to claims 1-8. In particular, the invention can also be applied to profiles which have more than just two side webs to be embedded in the concrete, as is the case, for example, with so-called external joint tapes.

Dabei besitzt dann vorzugsweise jede vorgesehene Seitenbahn bzw. Ankerrippenbahn einen erfindungsgemäßen Randstreifen 24.In this case, each side web or anchor rib web provided preferably has an edge strip 24 according to the invention.
