Abstract

The sealing tape has a foam strip (2) comprising two transverse surfaces (8) connected to lateral surfaces (6). A foil-type wrapping (4) surrounds the foam strip, and holds a foam strip in a precompressed state. The transverse surface (8) of the foam strip is pressed against a strip-like element (10) that is arranged inside the wrapping, where the strip-like element provides resistance to bending in a transverse direction. The transverse surface (8) of the foam strip is arranged opposite to the former transverse surface, and is firmly connected to the foil-type wrapping. An independent claim is also included for a method for sealing a joint by a sealing tape.

Description

Die Erfindung bezieht sich auf ein vorkomprimiertes Dichtband für das Abdichten einer Fuge, beispielsweise zwischen einem Rahmenprofil eines Fensters oder einer Tür und einer Gebäudewand.The invention relates to a precompressed sealing tape for sealing a joint, for example between a frame profile of a window or a door and a building wall.

Aus der EP 0 530 653 B1 ist eine Dichtleiste zum Ankleben an einem Fensterrahmen bekannt, die aus einem starren Kanal U-förmigen Querschnitts und einem darin angeordneten, elastisch komprimierten Schaumstoffstreifen besteht, der durch eine formstabile Deckleiste verschlossen ist, die randseitig in einer lösbaren Formschluss-Eingriffsverbindung zum Stirnbereich der Kanalwände gehalten ist. Die Deckleiste ist fahnenartig mit einem biegeschlaffen Streifenelement verbunden, das sich unter Führung über eine Randkante der Deckleiste hinweg in den Kanal der Dichtleiste hinein erstreckt. Durch Ziehen an dem Streifenelement lässt sich die Deckleiste von dem Kanal lösen, sodass sich der komprimierte Schaumstoffstreifen entspannen kann. Diese Konstruktion ist sehr aufwändig.From the EP 0 530 653 B1 a sealing strip for adhering to a window frame is known, which consists of a rigid channel U-shaped cross section and an elastically compressed foam strip disposed therein, which is closed by a dimensionally stable cover strip, the edge held in a releasable form-fitting engagement connection to the end region of the channel walls is. The cover strip is like a flag connected with a pliable strip element, which extends under leadership over a peripheral edge of the cover strip away into the channel of the sealing strip inside. By pulling on the strip element, the cover strip can be detached from the channel, so that the compressed foam strip can relax. This construction is very expensive.

In der US 4 204 373 ist ein Dichtband beschrieben, das aus einer flachen Leiste zum Ankleben an ein Rahmenprofil und einem darauf angeordneten Schaumstoffstreifen besteht. Der Schaumstoffstreifen ist von einer Folie aus Papier oder Kunststoff abgedeckt, die an der flachen Leiste angeklebt ist und den Schaumstoffstreifen im komprimierten Zustand hält. Im Randstreifen der Abdeckfolie verlaufen Aufreißfäden, mit deren Hilfe die Folie nach Installation des mit dem Dichtband versehenen Rahmenprofils im Bauwerk aufgerissen werden kann.In the US 4,204,373 a sealing tape is described, which consists of a flat bar for adhering to a frame profile and a foam strip arranged thereon. The foam strip is covered by a sheet of paper or plastic, which is glued to the flat bar and keeps the foam strip in the compressed state. In the edge strip of the cover run tear-open, with the help of which the film can be torn open after installation of the provided with the sealing strip frame profile in the building.

Aus der EP 1 131 525 B1 , die als nächstkommender Stand der Technik angesehen wird, ist ein vorkomprimiertes Dichtband bekannt, das aus einem elastisch rückstellfähigen Schaumstoffstreifen rechteckigen Querschnitts besteht, der in komprimiertem Zustand vollständig von einer Umhüllung umschlossen ist, die von einer Kunststofffolie gebildet ist. Die Kunststofffolie bildet eine in Längsrichtung des Dichtbandes verlaufende Reißlasche aus, indem die Kunststofffolie unter Bildung einer Sollreißstelle gegen sich selbst verhaftet ist. Zur Festlegung des Schaumstoffstreifens innerhalb der auf diese Weise gebildeten Tasche ist er an seiner Unterseite mit der Umhüllung verklebt, und die Umhüllung ist ihrerseits an ihrer Unterseite mit gesonderten Klebemitteln, beispielsweise einem doppelseitig klebenden Band, an einem Rahmenprofil anheftbar.From the EP 1 131 525 B1 Known as the closest prior art, a precompressed sealing tape is known, which consists of a resiliently elastic foam strip of rectangular cross-section, which is completely enclosed in the compressed state by a sheath which is formed by a plastic film. The plastic film forms a running in the longitudinal direction of the sealing strip tear tab by the plastic film is arrested to form a predetermined breaking point against itself. To fix the foam strip within the pocket formed in this way, it is glued on its underside with the wrapper, and the wrapper is in turn on its underside with separate adhesives, such as a double-sided adhesive tape, attachable to a frame profile.

Dichtbänder dieser Art werden an dem abzudichtenden Rahmenprofil angeklebt, und nach Montage des Rahmenprofils in einer Gebäudewandöffnung wird die Umhüllung aufgerissen, um es dem Schaumstoffstreifen zu ermöglichen, sich elastisch rückzustellen und damit das Rahmenprofil an der Gebäudewand abzudichten. Bei diesen bekannten Dichtbändern ist jedoch nachteilig, dass sie nur in relativ geringen Breiten hergestellt werden können, da sich ansonsten aufgrund der Rückstellkraft des vorkomprimierten Dichtbands eine ovale bis runde Form innerhalb der Umhüllung ergibt, welche für den Einbau ungeeignet ist. Im Rahmen der ständig steigenden Anforderungen an die Abdichtung in Gebäuden ist es aber wünschenswert, vorkomprimierte Dichtbänder in beliebigen Breiten bereitzustellen, um höhere Dichtwerte, eine bessere Wärmeisolierung und besseren Schallschutz zu erzielen.Sealing tapes of this type are adhered to the frame profile to be sealed, and after installation of the frame profile in a building wall opening the enclosure is torn open to allow the foam strip to resiliently reset and thus seal the frame profile on the building wall. In these known sealing tapes, however, it is disadvantageous that they can only be produced in relatively small widths, since otherwise due to the restoring force of the precompressed sealing tape, an oval to round shape results within the envelope, which is unsuitable for installation. However, in the context of ever-increasing requirements for sealing in buildings, it is desirable to provide precompressed sealing tapes in any widths to achieve higher sealing values, better thermal insulation and better soundproofing.

Der Erfindung liegt die Aufgabe zugrunde, ein vorkomprimiertes Dichtband zu schaffen, das einfach aufgebaut und leicht handhabbar ist und das in beliebigen Breiten geliefert werden kann.The invention has for its object to provide a precompressed sealing strip that is simple and easy to handle and that can be supplied in any widths.

Diese Aufgabe wird durch ein Dichtband mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a sealing tape with the features of claim 1.

Das erfindungsgemäße Dichtband umfasst einen elastisch rückstellfähigen, sich in Längsrichtung weiter als in Querrichtung erstreckenden Schaumstoffstreifen mit zwei Seitenflächen und mit zwei die Seitenflächen verbindenden Querflächen, und eine folienhafte Umhüllung, die den Schaumstoffstreifen vollständig umgibt und den Schaumstoffstreifen dadurch in einem vorkomprimierten Zustand hält. Mindestens eine Querfläche des Schaumstoffstreifens ist dabei gegen ein streifenförmiges Element gedrückt, welches innerhalb der Umhüllung angeordnet ist und in Querrichtung zumindest eine gewisse Biegesteifigkeit aufweist.The sealing tape of the invention comprises an elastically resilient, longitudinally wider than transversely extending foam strip having two side surfaces and two lateral surfaces connecting the side surfaces, and a film-like covering completely surrounding the foam strip and thereby holding the foam strip in a pre-compressed state. At least one transverse surface of the foam strip is pressed against a strip-shaped element, which is arranged within the envelope and has at least a certain bending stiffness in the transverse direction.

Dadurch wird gewährleistet, dass die komprimierte Rechteckform des Schaumstoffstreifens auch bei großen Breiten des Dichtbands erhalten bleibt und das Dichtband auf einfache Weise herstellbar und handhabbar ist.This ensures that the compressed rectangular shape of the foam strip is maintained even with large widths of the sealing strip and the sealing strip is easy to produce and manageable.

Vorzugsweise ist das streifenförmige Element in Längsrichtung biegeschlaff ausgebildet. In diesem Fall kann das Dichtband zu einer Rolle aufgewickelt sein, was den Transport und die Lagerung des Dichtbandes erheblich vereinfacht.Preferably, the strip-shaped element is formed slippery in the longitudinal direction. In this case, the sealing tape can be wound into a roll, which greatly simplifies the transport and storage of the sealing strip.

Vorzugsweise weist die Umhüllung eine sich in Längsrichtung erstreckende Reißlasche auf, die als Zugelement zum Öffnen der Umhüllung dient. Damit kann nach der Vormontage des Dichtbands auf einem abzudichtenden Rahmenbauteil die Umhüllung auf einfache Weise durch den Anwender geöffnet werden.Preferably, the wrapper has a longitudinally extending tear tab which serves as a tension member for opening the wrapper. Thus, after the pre-assembly of the sealing tape on a frame member to be sealed, the envelope can be opened in a simple manner by the user.

Alternativ hierzu kann das streifenförmige Element einen in Querrichtung über den Schaumstoffstreifen vorstehenden Endabschnitt aufweisen, der als Zugelement zum Öffnen der Umhüllung dient. In diesem Fall muss der Anwender nach Befestigung des Dichtbands am abzudichtenden Rahmenbauteil lediglich am vorstehenden Endabschnitt des streifenförmigen Elements ziehen, um die Umhüllung zu zerreißen und eine Expansion des Schaumstoffstreifens zu ermöglichen. Es ist auch möglich, die Umhüllung zunächst mittels einer Reißlasche zu öffnen und das streifenförmige Element anschließend herauszuziehen.Alternatively, the strip-shaped element may have a transversely over the foam strip projecting end portion which serves as a tension element for opening the enclosure. In this case, after attaching the sealing tape to the frame member to be sealed, the user only has to pull on the projecting end portion of the strip-shaped member to rupture the envelope and allow expansion of the foam strip. It is also possible to first open the envelope by means of a tear tab and then pull out the strip-shaped element.

Es kann jeweils vorteilhaft sein, dass die Umhüllung mit mindestens einer sich in Längsrichtung des Dichtbands erstreckenden Perforationslinie versehen ist, wodurch definierte Sollreißstellen gebildet werden und das Öffnen der Umhüllung vereinfacht wird.It may be advantageous in each case that the envelope is provided with at least one perforation line extending in the longitudinal direction of the sealing tape, whereby defined break points are formed and the opening of the envelope is simplified.

Um eine sichere Haftung des Schaumstoffstreifens an der Umhüllung auch nach Öffnen der Umhüllung zu gewährleisten, ist die zweite Querfläche des Schaumstoffstreifens, welche nicht gegen das streifenförmige Element gedrückt ist, mit einem doppelseitigen Klebestreifen ausgestattet.In order to ensure a secure adhesion of the foam strip to the sheath even after opening the sheath, the second transverse surface of the foam strip, which is not pressed against the strip-shaped element, equipped with a double-sided adhesive strip.

Zur weiteren Verstärkung der Rechteckform des Schaumstoffstreifens im vorkomprimierten Zustand kann im Bereich der zweiten Querfläche, welche nicht gegen das streifenförmige Element gedrückt ist, ein zweites streifenförmiges Element vorgesehen sein, welches ebenfalls in Querrichtung zumindest eine gewisse Biegesteifigkeit aufweist.To further reinforce the rectangular shape of the foam strip in the precompressed state, a second strip-shaped element may be provided in the region of the second transverse surface, which is not pressed against the strip-shaped element, which also has at least a certain flexural rigidity in the transverse direction.

Vorzugsweise ist dieses zweite streifenförmige Element ebenfalls innerhalb der Umhüllung angeordnet, sodass die Umhüllung, welche um beide streifenförmigen Elemente und den Schaumstoffstreifen herum angeordnet ist, ihre Kraft auf die Querflächen mittels der biegesteifen Elemente aufbringen kann.Preferably, this second strip-shaped element is also disposed within the enclosure so that the enclosure disposed about both strip-shaped elements and the foam strip can apply its force to the transverse surfaces by means of the rigid elements.

In diesem Fall verbindet der doppelseitige Klebestreifen den Schaumstoffstreifen vorzugsweise mit dem zweiten streifenförmigen Element, welches wiederum haftend mit der Umhüllung verbunden ist.In this case, the double-sided adhesive strip preferably connects the foam strip with the second strip-shaped element, which in turn is adhesively bonded to the enclosure.

Zur Anbringung an das abzudichtende Rahmenbauteil ist die Umhüllung vorzugsweise im Bereich der zweiten Querfläche, welche nicht gegen das erste streifenförmige Element gedrückt ist, an ihrer Außenseite von einem doppelseitigen Klebeband bedeckt, welches wiederum für einen sicheren Transport nach der Herstellung von einer Abdeckfolie überdeckt sein kann. Somit kann das erfindungsgemäße Dichtband bereits an dem abzudichtenden Rahmenbauteil vormontiert werden, und auf der Baustelle muss lediglich nach dem Einsetzen des Rahmenbauteils in die Gebäudeöffnung die Umhüllung geöffnet werden, um die Expansion des Schaumstoffstreifens zu ermöglichen.For attachment to the frame component to be sealed, the envelope is preferably covered in the region of the second transverse surface, which is not pressed against the first strip-shaped element, on its outer side by a double-sided adhesive tape, which in turn may be covered for safe transport after production of a cover , Thus, the sealing tape according to the invention can already be pre-assembled on the frame member to be sealed, and on the construction site, only after the insertion of the frame member in the building opening, the enclosure must be opened to allow the expansion of the foam strip.

Vorzugsweise ist die Umhüllung mit dem Endabschnitt auf beiden Seiten haftend verbunden, wodurch eine bessere Handhabung erzielt wird. Bei gleichzeitiger Anordnung von zwei Perforationslinien in der Umhüllung kann der Öffnungsvorgang perfektioniert werden.Preferably, the wrapper is adhesively bonded to the end portion on both sides, thereby providing better handling. With simultaneous arrangement of two perforation lines in the envelope, the opening process can be perfected.

Das seitliche Herausziehen des streifenförmigen Elements nach Öffnen der Umhüllung wird vorzugsweise dadurch weiter vereinfacht, dass das streifenförmige Element in Querrichtung Schlitze aufweist.The lateral extraction of the strip-shaped element after opening the cover is preferably further simplified in that the strip-shaped element has slots in the transverse direction.

In Wirklichkeit liegen diese Elemente jeweils eng aufeinander auf.In the drawings, foam strips, sheaths, adhesive tapes, strip-shaped elements and cover sheets are partially shown at a certain distance from each other to clearly distinguish the individual elements that make up the sealing strip. In reality, these elements are closely related.

In Fig. 1 ist ein Schaumstoffstreifen 2 dargestellt, der im dargestellten Beispiel einen rechteckigen Querschnitt hat, von einer folienhaften Umhüllung 4 umgeben ist und von dieser in einem vorkomprimierten Zustand gehalten wird. Der Schaumstoffstreifen 2 kann aus jedem beliebigen offenzelligen oder geschlossenzelligen Weichschaumstoff gebildet sein, z.B. aus Polyurethan oder Polyethylen, und kann für eine verzögerte Rückstellung imprägniert sein. Eine mehrlagige Anordnung mehrerer aufeinander laminierter unterschiedlicher Schaumstoffmaterialien ist ebenso denkbar wie die Anordnung einer imprägnierten Schaumstoffschicht auf einer nicht imprägnierten Schaumstoffschicht. Der Schaumstoffstreifen 2 erstreckt sich in seiner Längsrichtung weiter als in seiner Querrichtung und weist zwei Seitenflächen 6 und zwei Querflächen 8, 9 (Oberseite 8 und Unterseite 9) auf, welche die beiden Seitenflächen 6 verbinden.In Fig. 1 a foam strip 2 is shown, which in the illustrated example has a rectangular cross-section, is surrounded by a film-like envelope 4 and is held by this in a precompressed state. The foam strip 2 may be formed of any open cell or closed cell flexible foam, eg polyurethane or polyethylene, and may be impregnated for a delayed recovery. A multilayer arrangement of a plurality of different foam materials laminated on one another is just as conceivable as the arrangement of an impregnated foam layer on a non-impregnated foam layer. The foam strip 2 extends in its longitudinal direction further than in its transverse direction and has two side surfaces 6 and two transverse surfaces 8, 9 (top 8 and bottom 9), which connect the two side surfaces 6.

Das Material der Umhüllung 4 kann ein Folienmaterial, ein Gittergewebe, Papier oder anderes Material sein, das für den genannten Einsatzzweck geeignet ist. Außerdem sind auch laminierte Folien verwendbar, die aus einer Kunststofffolie bestehen, die mit einem Trägermaterial (z.B. Vlies) laminiert ist, oder gewebeverstärkte Folien. All diese Materialien sind mit dem Ausdruck "folienhaft" umschrieben. Auch Kombinationen dieser Materialien sind möglich. Bevorzugt ist allerdings eine thermoplastische Folie oder eine Schrumpffolie, welche sich unter Wärmeeinfluss zusammenzieht.The material of the envelope 4 may be a sheet material, a mesh fabric, paper or other material which is suitable for the stated purpose. In addition, laminated films composed of a plastic film laminated with a base material (e.g., nonwoven fabric) or fabric-reinforced films are also usable. All these materials are described by the term "film-like". Combinations of these materials are possible. However, preference is given to a thermoplastic film or a shrink film which contracts under the influence of heat.

Mindestens eine Querfläche, im vorliegenden Beispielsfall die Unterseite 9 des Schaumstoffstreifens 2, ist auf ein streifenförmiges Element 10 gedrückt, das in Querrichtung zumindest eine gewisse Biegesteifigkeit aufweist. Die Biegesteifigkeit sollte so hoch sein, dass das streifenförmige Element 10 die Kraft aufnimmt, welche von der Expansionsbestrebung des Schaumstoffstreifens 2 ausgeht und üblicherweise zu einer Verformung der flexiblen Umhüllung 4 hin zu einem Schlauch mit ovalem oder sogar rundem Querschnitt führen würde, ohne dabei selbst zu sehr verformt zu werden.At least one transverse surface, in the present example the underside 9 of the foam strip 2, is pressed onto a strip-shaped element 10 which has at least a certain flexural rigidity in the transverse direction. The bending stiffness should be so high that the strip-shaped element 10 absorbs the force which would result from the expansion tendency of the foam strip 2 and would normally lead to a deformation of the flexible covering 4 to a tube with an oval or even round cross-section, without self-closing to be very deformed.

Als Material des streifenförmigen Elements 10 kommt beispielsweise Pappe in Frage, es sind aber auch alle anderen möglichen biegesteifen Materialien, z.B. harte Kunststoffe, verwendbar. Das streifenförmige Element 10 ist vorzugsweise in Längsrichtung biegeschlaff ausgebildet, sodass das Dichtband zu einer Rolle aufgewickelt werden kann. Hier bietet sich beispielsweise einlagige Wellpappe mit nur einer Deckschicht an, wobei die Rippen bzw. Wellen in Querrichtung verlaufen. Das streifenförmige Element 10 kann einen vorstehenden Endabschnitt 12 aufweisen, der über eine Seitenfläche 6 des Schaumstoffstreifens 2 vorsteht und als Zugmittel zum Herausziehen dient. In einer bevorzugten Ausführungsform ist das streifenförmige Element 10 lediglich im Bereich des Endabschnitts 12 durchgängig ausgebildet, während über die restliche Breite in Querrichtung verlaufende Einschnitte im streifenförmigen Element 10 ausgebildet sind. Diese ermöglichen ein Verbiegen des streifenförmigen Elements 10 beim weiter unten beschriebenen Herausziehen nach dem Öffnen der folienhaften Umhüllung 4.As a material of the strip-shaped element 10, for example, cardboard comes into question, but it is also all other possible rigid materials, e.g. hard plastics, usable. The strip-shaped element 10 is preferably formed in the longitudinal direction limp, so that the sealing tape can be wound into a roll. Here, for example, offers single-ply corrugated board with only one cover layer, wherein the ribs or shafts in the transverse direction. The strip-shaped element 10 may have a projecting end portion 12, which projects beyond a side surface 6 of the foam strip 2 and serves as pulling means for pulling out. In a preferred embodiment, the strip-shaped element 10 is formed continuously only in the region of the end section 12, while incisions extending in the transverse direction over the remaining width are formed in the strip-shaped element 10. These allow a bending of the strip-shaped element 10 in the extraction described below after opening the film-like envelope 4th

Im Beispielsfall der Fig. 1, 3 und 4 ist der vorstehende Endabschnitt 12 dazu geeignet, das streifenförmige Element 10 zu fassen und durch das Ziehen nach außen die Umhüllung 4 zu öffnen. Hierzu kann in der Umhüllung 4 im Bereich der Seitenfläche 6, über welche der vorstehende Endabschnitt 12 des streifenförmigen Elements 10 vorragt, mindestens eine Perforationslinie 14 als Sollreißstelle vorgesehen sein. Die in Fig. 3 und 4 dargestellten Positionen der Perforationslinien 14 sind dabei bevorzugt, weil in diesem Fall nach dem Öffnen der Umhüllung 4 kein oder nur wenig Material an der Seitenfläche 6 verbleibt und ein großer Teil der Umhüllung, welcher nicht festgeklebt ist (siehe unten), am expandierenden Schaumstoffstreifen 2 entlanggleitet und sich über dessen anderer Seitenfläche 6 anordnet. Dies kann beispielsweise genutzt werden, wenn die Umhüllung 4 besondere Dichteigenschaften aufweist, welche zur besonderen Abdichtung der anderen Seitenfläche 6, beispielsweise im Sinne einer Dampfdiffusionsperre, dienen.In the example of the Fig. 1 . 3 and 4 For example, the protruding end portion 12 is adapted to grasp the strip-shaped element 10 and to open the envelope 4 by pulling it outwardly. For this purpose, at least one perforation line 14 may be provided as a predetermined tear in the envelope 4 in the region of the side surface 6, via which the projecting end portion 12 of the strip-shaped element 10 protrudes. In the 3 and 4 shown positions of the perforation lines 14 are preferred because in this case after opening the sheath 4 little or no material remains on the side surface 6 and a large part of the sheath, which is not stuck (see below), slides along the expanding foam strip 2 and arranges over the other side surface 6. This can be used, for example, if the envelope 4 has special sealing properties which serve for the special sealing of the other side face 6, for example in the sense of a vapor diffusion barrier.

Ebenso ist es möglich, die Umhüllung 4 durch Zug am vorstehenden Endabschnitt 12 auch ohne Perforationslinie 14 aufzureißen, wenn die Umhüllung 4 keinen großen Zugkräften widersteht., oder die Umhüllung mit einem Messer aufzuschneiden oder mit einem anderen Hllfsmittel zu öffnen.Likewise, it is possible to tear open the wrapper 4 by pulling on the protruding end portion 12 without perforation line 14, if the wrapper 4 does not withstand large tensile forces, or cut open the wrapper with a knife or open with another Hllfsmittel.

Ein doppelseitiger Klebestreifen 16 ist zwischen der anderen Querfläche des Schaumstoffstreifens 2, hier der Oberseite 8, und der Umhüllung 4 angeordnet und verbindet die beiden Elemente fest miteinander.A double-sided adhesive strip 16 is disposed between the other transverse surface of the foam strip 2, here the top 8, and the sheath 4 and connects the two Elements firmly together.

Ein Klebeband 18, das dem Anbringen des Dichtbandes an einem einzubauenden Bauelement, etwa einem Rahmenprofil, dient, ist im Bereich derselben Querfläche 8 auf der Außenseite der Umhüllung 4 befestigt. Die hier nach oben gewandte Außenseite des Klebebandes 18 ist vorzugsweise von einer gestrichelt dargestellten, abziehbaren Abdeckfolie 20, beispielsweise einem Silikonpapier 10 oder dergleichen, abgedeckt, solange das Dichtband nicht an dem Bauelement angebracht ist.An adhesive tape 18, which serves to attach the sealing strip to a component to be installed, for example a frame profile, is fastened in the region of the same transverse surface 8 on the outside of the envelope 4. The upwardly facing outside of the adhesive tape 18 is preferably covered by a peelable, peelable cover sheet 20, for example, a silicone paper 10 or the like, as long as the sealing tape is not attached to the component.

Es sei an dieser Stelle betont, dass in der Praxis das Klebeband 18 sehr häufig durch eine Klebeschicht realisiert ist, die an einem Silikonpapier oder dergleichen haftet und die in dieser Form auf die Umhüllung 4 aufkaschiert worden ist. Mitunter kann in dieser Klebeschicht noch ein Gittergewebe oder eine Trägerfolie, Vlies oder dergleichen zur Vergrößerung der Zugfestigkeit eingebettet sein. Der oben verwendete Ausdruck "Klebeband" soll daher auch Klebeschichten dieser hier beschriebenen Art umfassen. Dasselbe trifft für den Begriff "Klebestreifen" zu.It should be emphasized at this point that in practice the adhesive tape 18 is very often realized by an adhesive layer which adheres to a silicone paper or the like and which has been laminated in this form on the envelope 4. Occasionally, a mesh fabric or a carrier film, non-woven or the like may be embedded in this adhesive layer to increase the tensile strength. The term "adhesive tape" used above should therefore also encompass adhesive layers of this type described here. The same applies to the term "adhesive strip".

In Fig. 2 ist eine ähnliche Ausführungsform dargestellt, bei der die Umhüllung mittels einer Reißlasche 22 aufgerissen werden kann. Die beiden Abschnitte der Umhüllung 4 sind nahe dem Schaumstoffstreifen 2 durch eine Nahtlinie zusammengehalten, die eine Schweißnaht, Klebenaht oder Fadennaht sein kann und die durch Ziehen an der Reißlasche 22 geöffnet werden kann. Die Reißlasche 22 ist dabei entweder aus vorstehenden Teilabschnitten der Umhüllung 4 gebildet oder kann ein Faden oder dergleichen sein. In einem solchen Fall dient der vorstehende Endabschnitt 12 des streifenförmigen Elements 10 lediglich zur Entnahme desselben nach dem Öffnen der Umhüllung 4. Unter Umständen kann der vorstehende Endabschnitt 12 auch vollständig entfallen, wie in Fig. 2 dargestellt ist.In Fig. 2 a similar embodiment is shown in which the wrapper can be torn open by means of a tear tab 22. The two portions of the wrapper 4 are held together near the foam strip 2 by a seam line, which may be a weld, glued seam or suture, and which may be opened by pulling on the tear tab 22. The tear tab 22 is formed either from protruding sections of the enclosure 4 or may be a thread or the like. In such a case, the protruding end portion 12 of the strip-shaped member 10 serves only for removal thereof after the opening of the cover 4. In some circumstances, the projecting end portion 12 may also be completely omitted, as in Fig. 2 is shown.

Die in den Fig. 1 bis 4 dargestellten Ausführungsformen sind in einer eher idealisierten Gestalt des Querschnitts des Schaumstoffstreifens 2 dargestellt. In Wirklichkeit ist nämlich die obere Querfläche 8 des Schaumstoffstreifens 2 durch den von innen wirkenden Druck zumindest ein wenig in Richtung einer Kuppelform ausgedehnt, sodass der Querschnitt des Schaumstoffstreifens 2 im vorkomprimierten Zustand eine vom Rechteck in gewissem Umfang, wenn auch nicht zu stark abweichende Gestalt annimmt.The in the Fig. 1 to 4 illustrated embodiments are shown in a more idealized shape of the cross section of the foam strip 2. In fact, namely, the upper transverse surface 8 of the foam strip 2 is at least slightly expanded in the direction of a dome shape by the pressure acting from the inside, so that the cross-section of the foam strip 2 in the pre-compressed state assumes a certain extent, though not too different, shape from the rectangle ,

Zur weiteren Verstärkung der Rechteckform kann, wie in Fig. 3 dargestellt ist, zwischen der zweiten Querfläche, hier der Oberseite 8, und der Umhüllung 4 ein zweites streifenförmiges Element 24 angeordnet sein, welches mittels der Klebeschicht 16 mit dem Schaumstoffstreifen 2 und mittels eines weiteren Klebestreifens 26 mit der Umhüllung 4 verbunden ist. Dieses streifenförmige Element 24 besitzt dieselben Eigenschaften wie das erste streifenförmige Element 10 und würde nach dem Öffnen der Umhüllung 4 in der Fuge verbleiben. Der Klebestreifen 26 kann entfallen, wenn das streifenförmige Element 24 mit der Umhüllung auf andere Weise, z.B. durch Klebung oder Laminierung, haftend verbunden ist.To further enhance the rectangular shape, as in Fig. 3 is shown, between the second transverse surface, here the top 8, and the sheath 4, a second strip-shaped element 24 may be arranged, which is connected by means of the adhesive layer 16 with the foam strip 2 and by means of a further adhesive strip 26 with the sheath 4. This strip-shaped element 24 has the same properties as the first strip-shaped element 10 and would remain in the joint after the opening 4 has been opened. The adhesive strip 26 can be dispensed with if the strip-shaped element 24 is adhesively bonded to the covering in another way, for example by gluing or lamination.

Wie in Fig. 4 dargestellt ist, kann die Umhüllung 4 im Bereich des Endabschnitts 12 des streifenförmigen Elements 10 auch mit diesem haftend verbunden sein, z.B. durch Klebung oder durch Aneinanderlaminierung der beiden Elemente. Ebenso ist eine Naht denkbar, welche durch die beiden Schlaufen der Umhüllung 4 und den Endabschnitt 12 hindurchgeht, diese Elemente miteinander verbindet und gleichzeitig als Sollreißstelle der Umhüllung 4 dient. Alternativ kann in diesem Fall auch ein zusätzlicher L-förmiger Klebestreifen (nicht dargestellt) von außen über die Naht bis hin zu einer Perforationslinie 14 geklebt sein, die wie in Fig. 3 im Randbereich der Oberseite 8 angeordnet ist. Dadurch ist gewährleistet, dass die Zugkraft über die Naht hinweg zur Perforationslinie 14 übertragen wird.As in Fig. 4 is shown, the envelope 4 may be in the region of the end portion 12 of the strip-shaped member 10 also adhesively connected thereto, for example by gluing or by lamination of the two elements. Similarly, a seam is conceivable, which passes through the two loops of the envelope 4 and the end portion 12, these elements together and at the same time serves as a predetermined breaking point of the enclosure 4. Alternatively, in this case also an additional L-shaped adhesive strip (not shown) may be glued from the outside over the seam to a perforation line 14, which, as in FIG Fig. 3 is arranged in the edge region of the upper side 8. This ensures that the tensile force is transmitted across the seam to the perforation line 14.

Das vorkomprimierte Dichtband kann auf eine Rolle aufgewickelt angeboten werden oder als gerader Dichtbandstreifen vorbestimmter Länge verkauft werden. Das Dichtband kann mittels des Klebebandes 18 bereits vor dem Einbau oder sogar vor dem Transport des abzudichtenden Rahmenbauteils an diesem befestigt werden. Nach dem Einbau in die entsprechende Gebäudeöffnung vor Ort muss dann lediglich noch die Umhüllung 4 durch ein Messer oder durch Zug am vorstehenden Endabschnitt 12 bzw. an der Reißlasche 22 geöffnet werden. Dabei bleiben die am Rahmenbauteil verklebten Stellen der Umhüllung 4 und die wiederum damit verklebte Querfläche des Schaumstoffstreifens 2 an ihrem Ort haften, während der Schaumstoffstreifen 2 in Richtung der Querfläche, welche auf das erste streifenförmige Element 10 gedrückt war, expandiert und die Abdichtung der Fuge gewährleistet. Dabei gleitet der nicht mit dem Rahmenbauteil verklebte Teil der Umhüllung 4 am expandierenden Schaumstoffstreifen 2 entlang und bedeckt schließlich im Endzustand vorzugsweise zumindest einen Abschnitt der anderen Seitenfläche 6.The precompressed sealing tape can be offered wound up on a roll or sold as a straight strip of a predetermined length. The sealing tape can be fixed by means of the adhesive tape 18 before installation or even before the transport of the sealed frame member to this. After installation in the appropriate building opening on site then only the sheath 4 must be opened by a knife or train on the protruding end portion 12 and on the tear tab 22. The adhered to the frame member parts of the envelope 4 and the turn adhered thereto transverse surface of the foam strip 2 remain in place, while the foam strip 2 expands in the direction of the transverse surface which was pressed onto the first strip-shaped element 10 and ensures the sealing of the joint , In this case, the non-glued to the frame member part of the envelope 4 slides along the expanding foam strip 2 and finally covered in the final state preferably at least a portion of the other side surface. 6

In der Praxis sind die Schaumstoffstreifen 2 so vorkomprimiert, dass sie beim Entspannen vorzugsweise bis auf etwa das Fünf- bis Sechsfache ihrer im vorkomprimierten Zustand eingenommenen Dicke expandieren können, wovon aber nur etwa die Hälfte ausgenutzt wird, um eine sichere Anlage an dem Gebäudeteil zu gewährleisten, das dem abzudichtenden Profilelement gegenüberliegt.In practice, the foam strips 2 are precompressed so that they relax preferably to expand to about five to six times its occupied in the pre-compressed state thickness, but of which only about half is utilized to ensure a secure investment on the building part, which is opposite to the profile element to be sealed.

Die Erfindung wurde vorstehend am Beispiel eines Schaumstoffstreifens 1 mit rechteckigem Querschnitt beschrieben, weil dieses die Erläuterung der Erfindung und ihrer Merkmale sehr erleichtert. Mit "rechteckig" soll auch "quadratisch" umfasst sein. Der Fachmann erkennt indessen, dass sich die Erfindung in entsprechender Weise auch mit Schaumstoffstreifen 2 realisieren lässt, die vom Rechteck abweichende Querschnitte haben. Die angegebene Querschnittsgestalt des Schaumstoffstreifens 2 soll daher nicht einschränkend verstanden werden.The invention has been described above using the example of a foam strip 1 with a rectangular cross-section, because this greatly facilitates the explanation of the invention and its features. The term "rectangular" should also include "square". However, the person skilled in the art recognizes that the invention can also be implemented in a corresponding manner with foam strips 2 which have cross sections which deviate from the rectangle. The specified cross-sectional shape of the foam strip 2 should therefore not be understood as limiting.
