Abstract

A sealing tape is provided for sealing connecting joints between a window frame and a window embrasure in a building. The sealing tape is for adhering to the window frame and the window embrasure. The tape has an elastically moldable membrane base material; and a nonwoven layer of adhesion material covering at least one surface of the base material and which is elastically expandable in a lateral direction of the sealing tape for absorbing movements between the window frame and the window embrasure and which is substantially non-expandable in a longitudinal direction of the sealing tape so as to provide a sufficiently high yield strength of the sealing tape during use. The nonwoven layer is such that stucco or plaster can adhere to it.

Description

Die Erfindung bezieht sich auf ein Dichtungsband zum Abdichten von AnschluƟfugen zwischen einem Fensterrahmen und einer Fensterleibung eines Bauwerks. Ein Dichtungsband dieser Art ist beispielsweise aus der DE 296 105 456 U1 bekannt.The invention relates to a sealing tape for sealing connecting joints between a window frame and a window reveal of a building. A sealing tape of this type is known for example from DE 296 105 456 U1.

Um die AnschluƟfugen zwischen dem Fensterrahmen eines GebƤudes und der Leibung des zugehƶrigen Fensterschnitts gegen das Eindringen von Feuchtigkeit abzudichten, ist es aus der DE 296 05 456 U1 bekannt, bei der Montage des Fensterrahmens ein selbstklebendes Dichtungsband zwischen der InnenflƤche der Leibung und der RĆ¼ckseite des Fensterrahmens anzubringen. Beim anschlieƟenden Verputzen der InnenflƤche der Leibung wird das Dichtungsband durch den Putz- oder Gipsmƶrtel Ć¼berdeckt. Das bekannte Dichtungsband besteht aus einem klebrigen Butylkautschukstreifen, der auf seiner Unterseite mit einer abziehbaren Schutzschicht und auf seiner Oberseite mit einer Schicht aus Textilvlies bedeckt ist. Auf der Schicht am Textilvlies befindet sich an der Randzone eine schmale Klebeschicht, welche durch eine Abziehfolie geschĆ¼tzt ist. Bei der Montage werden nach Entfernen der Schutzschicht und der Abziehfolie die schmale Klebeschicht an der RĆ¼ckseite des Fensterrahmens befestigt, wƤhrend die freigelegte Unterseite des Butylkautschukstreifens gegen die InnenflƤche der Fensterleibung geklebt wird. Der freie Bereich des Textilvlies' bildet dabei eine Haftschicht fĆ¼r den Putz- oder Gipsmƶrtel.In order to seal the connection joints between the window frame of a building and the soffit of the associated window section against the ingress of moisture, it is known from DE 296 05 456 U1, during assembly of the window frame, a self-adhesive sealing tape between the inner surface of the soffit and the back of the window frame to install. During the subsequent plastering of the inner surface of the reveal, the sealing tape is covered by plaster or gypsum mortar. The known sealing tape consists of a sticky Butylkautschukstreifen, on its underside with a removable protective layer and is covered on its upper side with a layer of textile fleece. On the layer on the textile nonwoven there is a narrow adhesive layer at the edge zone, which is protected by a release liner. During assembly, after removing the protective layer and the release liner, the narrow adhesive layer is secured to the back of the window frame while the exposed bottom of the butyl rubber strip is adhered to the interior surface of the window reveal. The free area of the textile fleece forms an adhesive layer for the plaster or gypsum mortar.

Nachteilig an dem bekannten Dichtungsband ist indessen, daƟ es thermisch bedingte Bewegungen zwischen dem Fensterrahmen und der Fensterleibung nicht folgen kann, da die Schicht aus Textilvlies unelastisch ist. Diese fehlende ElastizitƤt kann dazu fĆ¼hren, daƟ sich Risse in der auf dem Textilvlies aufgetragenen Putzmƶrtelschicht bilden. Um diesem Nachteil zu begegnen, ist es in Weiterbildung des beschriebenen Dichtungsbandes bekannt (Produkt-Information "Fenster-Flexfolie innen" der Firma Illbruck Bau-Produkte GmbH & Co. KG, Leverkusen), als TrƤgermaterial fĆ¼r das Dichtungsband eine gewebeverstƤrkte, reiƟfeste Aluminiumfolie zu verwenden, welche einseitig mit einem Kunststoffvlies kaschiert ist. Die Aluminiumfolie ist mir einer lƶsbar fixierten Bewegungsschlaufe oder Dehnfalte ausgestattet, welche bei thermischen Bewegungen zwischen dem Fensterrahmen und der Fensterleibung als Dehnungsreserve dient. Die Verklebung mit dem Fensterrahmen und der Fensterleibung erfolgt durch Butylschichten auf beiden Seiten des Dichtungsbandes, welche durch Abziehfolien geschĆ¼tzt sind. Die lƶsbar fixierte Bewegungsschlaufe schrƤnkt indessen die Verlegungsmƶglichkeiten des bekannten Dichtungsbandes ein, da das Dichtungsband stets so auf den FensterrahmenrĆ¼cken geklebt werden muƟ, daƟ die Bewegungsschlaufe bzw. Dehnfalte mit der RahmeninnenflƤche abschlieƟt. Des weiteren ist die Herstellung der Bewegungsschlaufe bzw. Dehnfalte aufwendig und teuer.However, a disadvantage of the known sealing strip is that it can not follow thermally induced movements between the window frame and the window reveal, since the layer of textile nonwoven is inelastic. This lack of elasticity can lead to cracks forming in the plaster layer applied to the nonwoven fabric. To counter this disadvantage, it is known in development of the sealing strip described (product information "window flex film inside" the company Illbruck construction products GmbH & Co. KG, Leverkusen), as a carrier material for the sealing strip a fabric-reinforced, tear-resistant To use aluminum foil, which is laminated on one side with a plastic fleece. The aluminum foil is equipped with a releasably fixed movement loop or pleat which serves as a stretch reserve for thermal movements between the window frame and the window reveal. The bonding with the window frame and the window reveal is made by Butylschichten on both sides of the sealing strip, which are protected by peel-off films. The releasably fixed movement loop, however, restricts the possibility of laying the known sealing strip, since the sealing strip must always be glued to the window frame back so that the movement loop or expansion fold with the frame inner surface is completed. Furthermore, the production of the movement loop or pleats is complicated and expensive.

Aus der DE 20117273 U ist es bekannt, das Dichtungsland mit sich quer zur LƤngserstreckung verlaufenden Wellen zu versehen.From DE 20117273 U, it is known to provide the seal country with extending transversely to the longitudinal extension waves.

Die Aufgabe der Erfindung besteht demgegenĆ¼ber darin, ein Dichtungsband der eingangs erwƤhnten Art zu schaffen, welches Bewegungen zwischen dem Fensterrahmen und der Fensterleibung elastisch folgen kann und in der Herstellung einfach und billig ist.The object of the invention is in contrast to provide a sealing strip of the type mentioned above, which can follow movements between the window frame and the window reveal elastic and is easy and cheap to manufacture.

Diese Aufgabe wird erfindungsgemƤƟ durch die kennzeichnenden Merkmale des Anspruchs 1 gelƶst.This object is achieved by the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemƤƟen Dichtungsbandes ergeben sich aus den UnteransprĆ¼chen.Advantageous embodiments and further developments of the sealing strip according to the invention will become apparent from the dependent claims.

Die Erfindung beruht auf der Ɯberlegung, als TrƤgermaterial fĆ¼r das Dichtungsband eine elastisch verformbare Membrane aus Kunststofffolie vorzusehen. Auf dieser Membrane ist als Haftmaterial fĆ¼r Putz- oder Gipsmƶrtel eine Schicht aus Vlies aufkaschiert oder auflaminiert. Wesentlich ist, daƟ das Vlies in Querrichtung des Dichtungsbandes elastisch dehnbar ist zur Aufnahme von Bewegungen zwischen dem Fensterrahmen und der Fensterleibung. Des weiteren ist entscheidend, daƟ das verwendete Vlies in LƤngsrichtung des Dichtungsbandes nicht oder nur geringfĆ¼gig dehnbar ist, so daƟ bei der Verarbeitung des Dichtungsbandes das Vlies eine ausreichend hohe Streckfestigkeit besitzt. Vorzugsweise ist die Membrane beidseitig mit dem Haftmaterial aus Vlies beschichtet. Zur Verwendung im Innenbereich von Bauwerken besteht die elastisch verformbare Membrane aus einem diffusionsgeschlossenen Folienmaterial. Wasserdampf aus dem Inneren des Bauwerkes kann damit durch das Dichtungsband nicht hindurch in das Mauerwerk eindringen. Zur Verwendung im AuƟenbereich von Bauwerken besteht die elastisch verformbare Membrane aus einem diffusionsoffenen Folienmaterial. Der in das Bauwerk von auƟen eingedrungene Wasserdampf kann damit durch das Dichtungsband hindurch in die AuƟenumgebung austreten. Zur Befestigung des erfindungsgemƤƟen Dichtungsbandes an der Fensterleibung und am Fensterrahmen kƶnnen geeignete Selbstklebeschichten auf der einen oder auf beiden Vliesschichten vorgesehen werden. Alternativ zur Verwendung von Selbstklebeschichten kann auch ein FlĆ¼ssigkleber, beispielsweise ein Acrylat-Dispersions-Kleber, bei der Montage an den vorgesehenen Klebestellen des Fensterrahmens und der Fensterleibung aufgetragen werden. Als Material fĆ¼r die Kunststofffolie kommen vorzugsweise thermoplastische Kunststoffe wie beispielsweise Polyethylen zum Einsatz. Alternativ kann fĆ¼r die Kunststofffolie auch ein nicht-thermoplastischer Kunststoff wie beispielsweise Polyurethan verwendet werden. Als Material fĆ¼r das Vlies kommt vorzugsweise Kardenvlies zum Einsatz, fĆ¼r welches Kunststoffe wie Polyester, Polypropylen oder Polyethylen vorzugsweise vorgesehen werden kƶnnen.The invention is based on the consideration to provide as a carrier material for the sealing strip an elastically deformable membrane made of plastic film. On this membrane is a layer of nonwoven laminated or laminated as a bonding material for plaster or gypsum mortar. It is essential that the fleece in the transverse direction of the sealing strip is elastically stretchable for receiving movements between the window frame and the window reveal. Furthermore, it is crucial that the fleece used is not or only slightly stretchable in the longitudinal direction of the sealing strip, so that in the processing of the sealing strip, the fleece has a sufficiently high yield strength. Preferably, the membrane is on both sides with the adhesive material of fleece coated. For use in the interior of buildings, the elastically deformable membrane consists of a diffusion-closed film material. Water vapor from the interior of the structure can not penetrate through the sealing strip into the masonry. For use in the exterior of buildings, the elastically deformable membrane consists of a vapor-permeable sheet material. The penetrated into the building from the outside water vapor can thus escape through the sealing tape into the outside environment. To attach the sealing tape according to the invention to the window reveal and to the window frame, suitable self-adhesive layers can be provided on one or both nonwoven layers. Alternatively to the use of self-adhesive layers, a liquid adhesive, for example an acrylate dispersion adhesive, can also be applied during assembly to the intended splices of the window frame and the window reveal. As the material for the plastic film, preferably thermoplastic materials such as polyethylene are used. Alternatively, a non-thermoplastic plastic such as polyurethane can be used for the plastic film. As a material for the nonwoven preferably carded web is used, for which plastics as polyester, polypropylene or polyethylene may preferably be provided.

Das erfindungsgemƤƟe Dichtungsband gestattet nicht nur eine einfache, problemlose Abdichtung zwischen dem Fensterrahmen und der umgrenzenden Fensterleibung, sondern erlaubt auch das Aufbringen von Putz- oder Gipsmƶrtel auf die Vliesschicht, ohne daƟ die Gefahr einer spƤteren Bildung von Rissen infolge thermischer Bewegungen zwischen Fensterrahmen und Fensterleibung besteht. Derartige thermische Bewegungen werden durch die ElastizitƤt des erfindungsgemƤƟen Dichtungsbandes in Querrichtung vollstƤndig aufgenommen. Das erfindungsgemƤƟe Dichtungsband lƤƟt sich einfach und kostengĆ¼nstig dadurch herstellen, daƟ auf eine fortlaufend in LƤngsrichtung bewegte, Kunststofffolie einseitig oder zu beiden Seiten jeweils eine Vliesschicht durch Einwirkung von WƤrme und Druck auflaminiert oder unter Verwendung von dazwischen eingebrachtem Klebematerial unter Einwirkung von WƤrme und Druck aufkaschiert wird.The sealing strip according to the invention not only allows a simple, trouble-free sealing between the window frame and the bordering Fensterbelibung, but also allows the application of plaster or gypsum mortar on the nonwoven layer, without the risk of later formation of cracks due to thermal movements between the window frame and window reveal , Such thermal movements are completely absorbed by the elasticity of the sealing strip according to the invention in the transverse direction. The sealing strip according to the invention can be produced simply and inexpensively by laminating a nonwoven layer on one side or on both sides by exposure to heat and pressure or laminating it under application of heat and pressure using adhesive material interposed therebetween ,

Die Erfindung wird an Hand von AusfĆ¼hrungsbeispielen in den Zeichnungen nƤher erlƤutert.The invention will be explained in more detail with reference to exemplary embodiments in the drawings.

Das in Fig. 1 im Querschnitt dargestellte Dichtungsband 10 nach der Erfindung weist als TrƤgermaterial eine elastisch verformbare Membrane 1 aus Kunststofffolie auf. Als Material fĆ¼r die Kunststofffolie kommen vorzugsweise thermoplastische Kunststoffe wie beispielsweise Polyethylen zum Einsatz. Alternativ kann fĆ¼r die Kunststofffolie auch ein nicht-thermoplastischer Kunststoff wie beispielsweise Polyurethan verwendet werden. Die Membrane 1 ist im dargestellten AusfĆ¼hrungsbeispiel beidseitig mit Schichten 2 und 3 aus Vlies beschichtet. Als Material fĆ¼r das Vlies kommt vorzugsweise Kardenvlies zum Einsatz, fĆ¼r welches Kunststoffe wie Polyester, Polypropylen oder Polyethylen vorzugsweise vorgesehen werden kƶnnen. Die untere Vliesschicht 3 trƤgt im dargestellten Beispielsfall im Bereich ihrer beiden AuƟenrƤnder Selbstklebeschichten 4, 5, die jeweils mit einer Abziehfolie 4a bzw. 5a geschĆ¼tzt sind.The sealing strip 10 according to the invention shown in cross-section in FIG. 1 has, as a carrier material, an elastically deformable membrane 1 made of plastic film. As the material for the plastic film, preferably thermoplastic materials such as polyethylene are used. Alternatively, a non-thermoplastic plastic such as polyurethane can be used for the plastic film. The membrane 1 is coated on both sides with layers 2 and 3 of nonwoven fabric in the illustrated embodiment. As a material for the nonwoven preferably carded web is used, for which plastics such as polyester, polypropylene or Polyethylene may preferably be provided. The lower nonwoven layer 3 carries in the illustrated example in the region of its two outer edges self-adhesive layers 4, 5, which are each protected with a release liner 4a and 5a.

In Abwandlung der Darstellung in Fig. 1 kann bei einer in Fig. 6 gezeigten Variante eines Dichtungsbandes auch eine wechselseitige Anordnung der Selbstklebeschichten 4 und 5 vorgesehen werden, wie dies bei der AusfĆ¼hrungsform nach Fig. 2 gezeigt ist.In a modification of the illustration in Fig. 1, in a variant of a sealing strip shown in Fig. 6 and a mutual arrangement of the self-adhesive layers 4 and 5 are provided, as shown in the embodiment of FIG.

Zur Verwendung im AuƟenbereich von Bauwerken besteht die Membrane 1 aus einem diffusionsoffenen Folienmaterial, welches gleichzeitig wasserdicht ist. Infolge der diffusionsoffenen Eigenschaft der Membrane 1 kann Wasserdampf, welcher von auƟen in das Mauerwerk eingedrungen ist, durch das Dichtungsband 10 wieder nach auƟen austreten. Wesentlich ist ferner, daƟ das Folienmaterial der Membrane 1 wasserdicht ist, so daƟ Feuchtigkeit, wie Regen oder Schneewasser, von der AuƟenseite des Bauwerkes nicht durch die AnschluƟfuge zwischen Fensterrahmen und Fensterleibung ins Innere des Bauwerks eindringen kann. Die beiden Vliesschichten 2, 3 sind in Querrichtung des Dichtungsbandes 10 elastisch dehnbar, so daƟ sie zusammen mit der dazwischen liegenden Membrane 1 Bewegungen zwischen dem Fensterrahmen und der Fensterleibung elastisch aufnehmen kƶnnen. Dehnungsfalten, wie bei dem eingangs erwƤhnten Dichtungsband nach dem Stand der Technik, entfallen daher vollstƤndig. Des weiteren sind die Vliesschichten 2, 3 in LƤngsrichtung des Dichtungsbandes 10 nicht oder nur geringfĆ¼gig dehnbar, so daƟ bei der Verlegung des Dichtungsbandes 10 eine ausreichend hohe Streckfestigkeit gewƤhrleistet ist, wodurch eine Ɯberdehnung der zwischen den Vliesschichten 2, 3 liegenden Membrane 1 sicher vermieden wird. Die unterschiedliche Dehnbarkeit der Vliesschichten 2, 3 in Querrichtung einerseits und in LƤngsrichtung andererseits ergeben sich aus der speziellen textilen Struktur des verwendeten Vliesmaterials beispielsweise von Kardenvlies. Das Vlies der Schichten 2, 3 stellt gleichzeitig ein hervorragendes Haftmaterial fĆ¼r Putz- oder Gipsmƶrtel dar, so daƟ nach der Verlegung des Dichtungsbandes 10 die auf der Fensterleibung freiliegende Vliesschicht mit Putz beschichtet oder mit Wandfarbe bestrichen werden kann. Die gefaserte Struktur der Vliesschichten 2, 3 bietet gleichzeitig einen optisch und Ƥsthetisch hervorragenden Anblick, so daƟ in vielen FƤllen das Auftragen von Wandfarbe ausreichend ist. Zum Ankleben an den Fensterrahmen und an die Fensterleibung dienen bei der in Fig. 1 dargestellten AusfĆ¼hrungsform die Selbstklebeschichten 4 und 5, welche beispielsweise aus Butyl-Kautschuk oder aus einem Acrylat-Kleber bestehen. Die Abziehfolien 4a und 5a werden unmittelbar vor dem Ankleben der Schichten 4, 5 entfernt. Anstelle von Selbstklebeschichten 4, 5 ist es auch mƶglich, auf die Klebebereiche des Fensterrahmens und der Fensterleibung bei der Verlegung des Dichtungsbandes 10 einen FlĆ¼ssigkleber aufzutragen, beispielsweise einen Acrylat-Dispersions-Kleber, wie er unter der Bezeichnung "Folienfix" bekannt ist.For use in the exterior of buildings, the membrane 1 consists of a vapor-permeable film material, which is waterproof at the same time. As a result of the vapor-permeable property of the membrane 1, water vapor, which has penetrated from the outside into the masonry, can escape through the sealing strip 10 to the outside again. It is also essential that the film material of the membrane 1 is waterproof, so that moisture, such as rain or snow, from the outside of the building not through the joint between the window frame and Window reveal can penetrate into the interior of the building. The two nonwoven layers 2, 3 are elastically stretchable in the transverse direction of the sealing strip 10, so that they can absorb elastically together with the membrane 1 therebetween movements between the window frame and the window reveal. Expansion creases, as in the case of the sealing strip according to the prior art mentioned above, are therefore completely eliminated. Furthermore, the nonwoven layers 2, 3 are not or only slightly stretchable in the longitudinal direction of the sealing strip 10, so that when the sealing strip 10 is laid, a sufficiently high yield strength is ensured, whereby an overstretching of the membrane 1 lying between the nonwoven layers 2, 3 is reliably avoided , The different extensibility of the nonwoven layers 2, 3 in the transverse direction on the one hand and in the longitudinal direction on the other hand result from the special textile structure of the nonwoven material used, for example carded fleece. The nonwoven layer 2, 3 at the same time represents an excellent adhesive material for plaster or gypsum mortar, so that after the installation of the sealing strip 10 exposed on the Fensterbelibung nonwoven layer can be coated with plaster or painted with wall paint. The fiberized structure of the nonwoven layers 2, 3 offers both a visual and aesthetic excellent sight, so that in many cases, the application of wall paint is sufficient. For sticking to the window frame and the window reveal serve in the embodiment shown in Fig. 1, the self-adhesive layers 4 and 5, which consist for example of butyl rubber or of an acrylate adhesive. The peel-off films 4a and 5a are removed immediately before the adhering of the layers 4, 5. Instead of self-adhesive layers 4, 5, it is also possible to apply a liquid adhesive, for example an acrylate dispersion adhesive, as it is known under the name "Folienfix" on the adhesive areas of the window frame and the window reveal during the installation of the sealing strip 10.

Als Material fĆ¼r die Membrane 1 kommt beispielsweise eine PolyethylenFolie in Betracht. Die Vliesschichten 2, 3 bestehen beispielsweise aus Polyester- oder Polypropylen-Vlies. Verwendetes Polyester-Vlies weist beispielsweise ein Gewicht von 40 g/m2 auf. Das als Rollenware verfĆ¼gbare Dichtungsband 10 besitzt beispielsweise ein Gewicht von 125 g/m2 und weist bei einer Gesamtbreite von beispielsweise 1.500 mm und einer Gesamtdicke von 0,8 mm eine RollenlƤnge von 10 oder 50 Metern auf.As a material for the membrane 1 is for example a polyethylene film into consideration. The nonwoven layers 2, 3 consist for example of polyester or polypropylene nonwoven. For example, used polyester nonwoven has a weight of 40 g / m 2 . The sealing tape 10 available as a roll has, for example, a weight of 125 g / m 2 and, with a total width of, for example, 1,500 mm and a total thickness of 0.8 mm, has a roll length of 10 or 50 meters on.

Auf Grund seiner Zusammensetzung weist das erfindungsgemƤƟe Dichtungsband gegenĆ¼ber Sonneneinwirkung sowie gegen SƤuren und Laugen, wie sie im Regenwasser vorhanden sind, eine extrem hohe BestƤndigkeit auf. Das an sich bereits UV-bestƤndige Folienmaterial der Membrane 1 wird zusƤtzlich durch die lichtundurchlƤssigen Vliesschichten 2, 3 gegen Sonnenlicht abgedeckt und geschĆ¼tzt.Due to its composition, the sealing tape according to the invention against sunlight and against acids and alkalis, as they are present in rainwater, an extremely high resistance. The already UV-resistant film material of the membrane 1 is additionally covered by the opaque nonwoven layers 2, 3 against sunlight and protected.

Die in Fig. 2 dargestellte AusfĆ¼hrungsform des erfindungsgemƤƟen Dichtungsbandes 10 unterscheidet sich von der AusfĆ¼hrungsform nach Fig. 1 zunƤchst dadurch, daƟ die Selbstklebeschichten 4 und 5 wechselseitig an den AuƟenrƤndern beider Vliesschichten 2, 3, und zwar diagonal gegenĆ¼berliegend angeordnet sind. Des weiteren ist das Dichtungsband 10 nach Fig.2 zur Verwendung im Innenbereich von Bauwerken vorgesehen. Die Membrane 1 des Dichtungsbandes 10 nach Fig.2 besteht daher aus einem diffusionsgeschlossenen Folienmaterial. Durch diese Eigenschaft wird Wasserdampf, der sich im Inneren des Bauwerks beispielsweise bei der AbkĆ¼hlung der Raumluft bildet, daran gehindert, durch das Dichtungsband 10 hindurch in das Mauerwerk einzutreten. Ansonsten gelten die zu der AusfĆ¼hrungsform nach Fig. 1 angegebenen Eigenschaften in gleicher Weise auch fĆ¼r AusfĆ¼hrungsform nach Fig. 2.The illustrated in Fig. 2 embodiment of the sealing strip 10 according to the invention differs from the embodiment of FIG. 1, first, characterized in that the self-adhesive layers 4 and 5 mutually opposite to the outer edges of both nonwoven layers 2, 3, and are arranged diagonally opposite. Furthermore, the sealing tape 10 is provided according to Figure 2 for use in the interior of buildings. The membrane 1 of the sealing strip 10 according to Figure 2 therefore consists of a diffusion-closed sheet material. By this property is water vapor, which forms inside the building, for example, during the cooling of the room air, it prevented from entering through the sealing tape 10 into the masonry. Otherwise, the properties specified for the embodiment according to FIG. 1 also apply in the same way to the embodiment according to FIG. 2.

Die AusfĆ¼hrungsformen nach Fig. 1 und 2 lassen sich auch miteinander kombinieren, wie aus Fig. 3 ersichtlich ist. Das in Figur 3 gezeigte linke Dichtungsband 10a ist fĆ¼r den AuƟenbereich vorgesehen und weist dementsprechend eine dampfdiffusionsoffene Membrane 1 auf. Dagegen ist das in Figur 3 gezeigte rechte Dichtungsband 10b fĆ¼r den Innenbereich vorgesehen und weist dementsprechend eine dampfdiffusionsgeschlossene Membrane 1 auf. Die beiden DichtungsbƤnder 10a, 10b sind durch die Klebeschicht 4 des rechten Dichtungsbandes 10b miteinander verbunden.The embodiments according to FIGS. 1 and 2 can also be combined with one another, as can be seen from FIG. 3. The left-hand sealing strip 10a shown in FIG. 3 is intended for outdoor use and accordingly has a vapor diffusion-open membrane 1. By contrast, the right-hand sealing strip 10b shown in FIG. 3 is intended for the interior and accordingly has a membrane 1 closed to vapor diffusion. The two sealing tapes 10a, 10b are interconnected by the adhesive layer 4 of the right-hand sealing tape 10b.

Die Figuren 4 bis 6 zeigen verschiedene Verlegebeispiele fĆ¼r das erfindungsgemƤƟe Dichtungsband 10 auf der AuƟenseite eines Bauwerks 20 (Figuren 4 und 6) und auf der Innenseite des Bauwerks 20 (Fig. 5). Die AuƟenseite der Fensterleibung des Bauwerks 20 ist in den Figuren 4 bis 6 mit 20a bezeichnet, wƤhrend die Innenseite der Fensterleibung in den Figuren 4 und 5 mit 20b bezeichnet ist. Das nur schematisch angedeutete Dichtungsband 10 wird zwischen dem als Hohlprofil gezeigten Fensterrahmen 30 des Fensters 40 und der AuƟenseite 20a bzw. Innenseite 20b der Fensterleibung verlegt, so daƟ die AnschluƟfuge zwischen Fensterleibung und Fensterrahmen feuchtigkeitsdicht nach auƟen (Figuren 4 und 6) bzw. nach innen (Fig.5) abgedichtet ist.. Das Band 10 klebt dabei mit seinem einen Randbereich an der RĆ¼ckseite (Figuren 5 und 6) bzw. an der AuƟenseite (Fig. 4) des Fensterrahmens 30 und mit seinem anderen Randbereich an dem Mauerwerk der Fensterleibung. Zum Befestigen des Fensterrahmens 30 in der Fensterleibung ist bei den Verlegebeispielen nach Figuren 4 und 5 ein Kunststoffschaum 60, vorzugsweise Polyurethanschaum in die Fuge zwischen Fensterrahmen 30 und Fensterleibung bis zum Dichtungsband 10 eingespritzt. Ferner befindet sich im Falle von Fig. 5 zwischen dem Fensterrahmen 30 und der AuƟenseite 20a der Fensterleibung eine elastische Verfugung 70. Wie Fig. 5 ferner zeigt, erstreckt sich das Dichtungsband 10 mit seinem unteren Randbereich Ć¼ber einen Teil der Innenseite 20b der Fensterleibung. Dieser Randbereich des Dichtungsbandes liegt unter einer Schicht 50 aus Mƶrtel- oder Gipsputz, mit welchem der Fensterrahmen in der inneren Fensterleibung verputzt ist. In Ƥhnlicher Weise ist bei dem Verlegebeispiel nach Fig. 4 eine Schicht 100 aus Mƶrtelputz auf der AuƟenseite 20a der Fensterleibung aufgebracht, welche den darauf geklebten Schenkel des Dichtungsbandes 10 Ć¼berdeckt. Durch die Verwendung der Vliesschichten 2 und 3 (Fig. 1) des erfindungsgemƤƟen Dichtungsbandes 10 haftet der Mƶrtel- oder Gipsputz problemlos auf dem verlegten Dichtungsband 10.Figures 4 to 6 show various installation examples for the sealing strip 10 according to the invention on the outside of a building 20 (Figures 4 and 6) and on the inside of the structure 20 (Fig. 5). The outside of the window reveal of the building 20 is shown in FIGS. 4 6 to 20a, while the inner side of the window reveal in FIGS. 4 and 5 is denoted by 20b. The only schematically indicated sealing strip 10 is laid between the window frame 30 of the window 40 shown as a hollow profile and the outer side 20a or inner side 20b of the window reveal, so that the connecting joint between the window reveal and window frame moisture-proof to the outside (Figures 4 and 6) or to the inside The tape 10 sticks with its one edge region on the rear side (FIGS. 5 and 6) or on the outside (FIG. 4) of the window frame 30 and with its other edge region on the masonry of the window reveal , For fixing the window frame 30 in the window reveal a plastic foam 60, preferably polyurethane foam is injected into the joint between the window frame 30 and window reveal up to the sealing strip 10 in the laying examples of Figures 4 and 5. Further, in the case of Fig. 5, there is an elastic joint 70 between the window frame 30 and the outside 20a of the soffit. As shown in Fig. 5, the sealing strip 10 extends with its lower edge portion over part of the inner side 20b of the sash. This edge region of the sealing strip lies beneath a layer 50 of mortar or gypsum plaster, with which the window frame is plastered in the inner window reveal. Similarly, in the laying example of FIG. 4, a layer 100 of mortar plaster is applied on the outside 20a of the window reveal, which covers the leg of the sealing strip 10 glued thereon. By using the nonwoven layers 2 and 3 (FIG. 1) of the sealing strip 10 according to the invention, the mortar or gypsum plaster adheres without problem to the laid sealing strip 10.

Bei dem Verlegebeispiel nach Fig. 6 erstreckt sich das Dichtungsband 10 unterhalb eines Traufbleches 80 auf der AuƟenseite 20a der Fensterleibung eines Bauwerks 20. Der Fensterrahmen 30 des Fensters 40 stĆ¼tzt sich an seiner Innenseite auf einem Fensterbrett 90 ab, welches bis zum Innenrand des Dichtungsbandes 10 reicht.6, the sealing strip 10 extends below a eaves panel 80 on the outer side 20a of the window reveal of a building 20. The window frame 30 of the window 40 is supported on its inner side on a window sill 90 which extends to the inner edge of the sealing strip 10 enough.

Zum Ankleben des Dichtungsbandes 10 an den Fensterrahmen 30 und an die AuƟen- bzw. Innenseite 20a, 20b der Fensterleibung dienen im Falle der Verlegebeispiele nach Figuren 4 und 5 die in den Figuren 1 bzw. 2 gezeigten Selbstklebeschichten 2, 3, deren Abziehfolien 3a, 4a unmittelbar vor Verlegung entfernt werden. Im Falle des Verlegebeispiels nach Fig.6 wird die Variante des Dichtungsbandes 10 nach Fig. 1 mit wechselseitig angeordneten Selbstklebeschichten 2, 3 verwendet. Wie bereits erwƤhnt, ist die Verwendung von Selbstklebeschichten 2, 3 nicht zwingend erforderlich. Das ohne Selbstklebeschichten 2, 3 ausgebildete Dichtungsband 10 kann auch dadurch an dem Fensterrahmen 30 und der Fensterleibung befestigt werden, daƟ unmittelbar vor dem Verlegen ein FlĆ¼ssigkleber, beispielweise ein Acrylat-Dispersions-Kleber, auf die Klebestellen aufgetragen wird.For gluing the sealing strip 10 to the window frame 30 and to the outer or inner side 20a, 20b of the window reveal serve in the case of laying examples according to Figures 4 and 5, the self-adhesive layers 2, 3 shown in Figures 1 and 2, the release sheets 3a, 4a be removed immediately before installation. In the case of the laying example according to FIG. 6, the variant of the sealing strip 10 according to FIG. 1 with mutually arranged self-adhesive layers 2, 3 is used. As already mentioned, the use of self-adhesive layers 2, 3 is not mandatory. The sealing tape 10 formed without self-adhesive layers 2, 3 can also be attached to the window frame 30 and the window reveal that immediately before laying a liquid adhesive, such as an acrylate dispersion adhesive, is applied to the splices.

Bei einer weiteren in Fig. 7 im Querschnitt dargestellten AusfĆ¼hrungsform eines Dichtungsbandes 10 fĆ¼r den AuƟenbereich ist eine wechselseitige Anordnung der Selbstklebeschichten 4 und 5 an den beiden Vliesschichten 2, 3 vorgesehen. FĆ¼r die Membrane 1 gelten die fĆ¼r die Verwendung im AuƟenbereich von Bauwerken bereits angegebenen Werkstoffe und Eigenschaften. Ein solches Dichtungsband 10 mit wechselseitig angeordneten Selbstklebeschichten 2, 3 wird, wie schon erwƤhnt, bei dem Verlegebeispiel nach Fig. 6 verwendet. ZusƤtzlich zu den AusfĆ¼hrungsformen nach Figuren 1 bis 3 trƤgt die Vliesschicht 3 bei dem Dichtungsband 10 nach Fig. 7 eine schwach klebende Haftschicht 6, welche mit einer Abziehfolie 6a geschĆ¼tzt ist. Die schwach klebende Haftschicht 6 erstreckt sich im Randbereich des Dichtungsbandes 10 gegenĆ¼ber der Selbstklebeschcht 5, wobei jedoch die LƤnge der Haftschicht 6 wesentlich geringer ist als die LƤnge der gegenĆ¼berliegenden Selbstklebeschicht 5. Die Haftschicht 6 dient lediglich zur Befestigung des damit versehenen Bandendes bei der Vormontage des Dichtungsbandes 10 an einem Fensterrahmen 30. Wie hierzu aus Fig. 7 ersichtlich ist, wird bei dieser Vormontage das Dichtungsband 10 mit seiner Selbstklebeschicht 4 an der dem Bauwerk 20 zugewandten Stirnseite des Fensterrahmens 30 angeklebt (nach vorherigem Entfernen der Abziehfolie 4 a). Um zu vermeiden, daƟ das vormontierte Dichtungsband 10 mit seinem freien Ende am Fensterrahmen 30 schlaff nach unten hƤngt und dadurch das Dichtungsband 10 beim Transport oder beim Einbau des Fensterrahmens 30 in die Fensterleibung des Bauwerks 20 verschmutzt, beschƤdigt oder abgerissen wird, wird das freie Ende des Dichtungsbandes 10 mit Hilfe der schwach klebenden Haftschicht 6 nach vorherigem Entfernen der Abziehfolie 6a an der AuƟenseite des Fensterrahmens 30 angeheftet, wie dies aus Fig. 8 ersichtlich ist. Nach erfolgtem Einbau des Fensterrahmens 30 in die Fensterleibung des Bauwerks 20 wird das freie Ende des Dichtungsbandes 10 von der AuƟenseite des Fensterrahmens 30 abgelƶst und mit seiner Selbstklebeschicht 5 (nach Entfernen der Abziehfolie 5a) an dem Bauwerk 20 angeklebt, wie dies aus Fig. 9 ersichtlich ist.In a further embodiment of a sealing strip 10 for outdoor use, shown in cross section in FIG. 7, a mutual arrangement of the self-adhesive layers 4 and 5 on the two nonwoven layers 2, 3 is provided. For membrane 1, the materials and properties already specified for outdoor use apply. Such a sealing tape 10 with mutually arranged self-adhesive layers 2, 3 is, as already mentioned, used in the laying example of FIG. In addition to the embodiments according to FIGS. 1 to 3, the nonwoven layer 3 contributes the sealing tape 10 of FIG. 7, a weak adhesive bonding layer 6, which is protected with a release liner 6a. The weakly adhering adhesive layer 6 extends in the edge region of the sealing strip 10 with respect to the Selbstklechtscht 5, but the length of the adhesive layer 6 is substantially less than the length of the opposite self-adhesive layer 5. The adhesive layer 6 is used only for attachment of the thus provided tape end in the pre-assembly of As can be seen from FIG. 7, in this pre-assembly, the sealing tape 10 with its self-adhesive layer 4 is glued to the front side of the window frame 30 facing the structure 20 (after previously removing the release liner 4 a). In order to avoid that the pre-assembled sealing strip 10 with its free end on the window frame 30 slack down and thus the sealing strip 10 during transport or installation of the window frame 30 in the window reveal of the structure 20 is dirty, damaged or demolished, the free end of the sealing tape 10 is adhered to the outside of the window frame 30 by means of the weakly adhering adhesive layer 6 after previously removing the peel-off film 6a, as shown in FIG. After installation of the window frame 30 in the window reveal of the building 20, the free end of the sealing strip 10 is detached from the outside of the window frame 30 and glued with its self-adhesive layer 5 (after removal of the release liner 5a) to the building 20, as can be seen from Fig. 9.

Es versteht sich, daƟ die schwach klebende Haftschicht 6 mit Abziehfolie 6a auch bei einem Dichtungsband 10 nach den Figuren 1, 2 oder 3 vorgesehen werden kann, da auch bei diesen DichtungsbƤndem 10 das Problem besteht, daƟ im Falle einer Vormontage des Dichtungsbandes 10 an einem Fensterrahmen 30 das freie Ende des Dichtungsbandes 10 schlaff nach unten hƤngt und beim Transport oder beim Verlegen des Fensterrahmens 30 verschmutzt, beschƤdigt oder abgerissen werden kann.It is understood that the weakly adherent adhesive layer 6 with release liner 6a can be provided even with a sealing strip 10 according to Figures 1, 2 or 3, since even with these DichtungsbƤndem 10 the problem is that in the case of pre-assembly of the sealing strip 10 at a Window frame 30, the free end of the sealing strip 10 slack down hanging and dirty during transport or when laying the window frame 30, can be damaged or demolished.

Die schwach klebende Haftschicht 6 besteht beispielsweise aus einem Acrylatkleber, welcher sich nach erfolgtem Ankleben an die AuƟenseite des Fensterrahmens 30 wieder leicht ablƶsen lƤƟt.The weakly adhesive bonding layer 6 consists for example of an acrylate adhesive, which can easily be detached again after adhering to the outside of the window frame 30.

Zur Herstellung des erfindungsgemƤƟen Dichtungsbandes 10 wird beispielsweise auf eine fortlaufend in LƤngsrichtung bewegte, thermoplastische Kunststofffolie einseitig oder zu beiden Seiten jeweils eine Vliesschicht durch Einwirkung von WƤrme und Druck auflaminiert. Dabei wird die OberflƤche der thermoplastischen Kunststofffolie angeschmolzen, die dann mit den Vliesschichten verklebt. Alternativ kann zwischen die beiden OberflƤchen einer aus thermoplastischen oder nichtthermoplastischen Kunststoffen bestehende Folie und den beiden Vliesschichten ein FlĆ¼ssigkleber eingespritzt werden, worauf alle drei Schichten unter Einwirkung von WƤrme und Druck miteinander verklebt (kaschiert) werden.To produce the sealing strip 10 according to the invention For example, on a continuously moving in the longitudinal direction, thermoplastic film laminated on one side or on both sides in each case a nonwoven layer by the action of heat and pressure. In this case, the surface of the thermoplastic film is melted, which then adhered to the nonwoven layers. Alternatively, a liquid adhesive can be injected between the two surfaces of a film consisting of thermoplastic or non-thermoplastic plastics and the two nonwoven layers, whereupon all three layers are bonded together (laminated) under the action of heat and pressure.
