Abstract

The tape has a foam strip (2) made of flexible foam i.e. polyurethane, and including a pair of side surfaces (4), a top surface (6) and a bottom surface (8), where the side surfaces are extended along a longitudinal direction (B). The foam strip consists of a set of three-dimensional foam segments (10) separated from each other by a set of cuts (12) downwardly extended from the top surface into the foam strip. Few of the foam segments are completely surrounded in the longitudinal direction and in a transverse direction (A) by the other foam segments.

Description

Die Erfindung betrifft ein Dichtband aus weichem Schaumstoff zum Abdichten einer Fuge, beispielsweise zwischen einem Bauteil wie einem Rahmenprofil eines Fensters oder einer Tür und einer Gebäudewand.The invention relates to a sealing tape made of soft foam for sealing a joint, for example between a component such as a frame profile of a window or a door and a building wall.

Dichtbänder dieser Art werden an dem abzudichtenden Bauteil angeklebt, und nach Montage des Bauteils in einer Gebäudewandöffnung expandiert der zuvor komprimierte Schaumstoffstreifen, stellt sich also elastisch zurück, und dichtet damit das Bauteil an der Gebäudewand ab. Bei diesen bekannten Dichtbändern ist jedoch nachteilig, dass bei ungleichmäßigem Mauerwerk die Abdichtfunktion teilweise zu wünschen übrig lässt. Dies gilt insbesondere bei großen Unebenheiten im Mauerwerk der abzudichtenden Fuge.Sealing tapes of this type are adhered to the component to be sealed, and after assembly of the component in a building wall opening expands the previously compressed foam strips, so is elastic back, and thus seals the component on the building wall. However, in these known sealing tapes, it is disadvantageous that, in the case of uneven masonry, the sealing function leaves something to be desired in part. This is especially true for large bumps in the masonry of the joint to be sealed.

Der Erfindung liegt die Aufgabe zugrunde, ein Dichtband zu schaffen, das einfach aufgebaut ist und auch bei großen Unebenheiten im Mauerwerk der abzudichtenden Fuge eine hervorragende Isolierwirkung besitzt.The invention has for its object to provide a sealing strip which is simple and has excellent insulation even with large bumps in the masonry of the joint to be sealed.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß weist das Dichtband einen Schaumstoffstreifen aus weichem Schaumstoff auf, der zwei Seitenflächen, eine Oberseite und eine Unterseite aufweist. Dabei weist der Schaumstoffstreifen eine Mehrzahl von dreidimensionalen Schaumstoffsegmenten auf, die durch Einschnitte, welche sich von der Oberseite aus in den Schaumstoffstreifen erstrecken, voneinander getrennt sind.According to the invention, the sealing strip has a foam strip made of soft foam, which has two side surfaces, an upper side and a lower side. In this case, the foam strip on a plurality of three-dimensional foam segments, which are separated by incisions extending from the top of the foam strip, from each other.

Durch die segmentierte Ausgestaltung des Schaumstoffstreifens mit eng aneinander liegenden Schaumstoffsegmenten, die sich jeweils unabhängig voneinander ausdehnen können, gelingt es, auch große Unebenheiten des Mauerwerks zu kompensieren. Aufgrund der üblicherweise äußerst schmalen Einschnitte sind die einzelnen Schaumstoffsegmente zwar voneinander getrennt, liegen aber eng aneinander an, sodass eine maximale Dichtwirkung beibehalten wird. Außerdem ist die Herstellung eines derartigen Dichtbands relativ einfach.Due to the segmented design of the foam strip with closely spaced foam segments, which can each extend independently, it is possible to compensate for large unevenness of the masonry. Due to the usually extremely narrow cuts, the individual foam segments are separated, but are close together, so that a maximum sealing effect is maintained. In addition, the production of such a sealing tape is relatively simple.

Um eine Überbrückung großer Unebenheiten im Mauerwerk sicherzustellen, erstrecken sich die Schaumstoffsegmente im expandiertem Zustand des Schaumstoffstreifens über mindestens 50 % seiner Höhe, vorzugsweise mindestens 60 % seiner Höhe, mehr bevorzugt mindestens 70 % seiner Höhe, noch mehr bevorzugt mindestens 90 % seiner Höhe.In order to ensure bridging of large imperfections in the masonry, the foam segments extend in the expanded state of the foam strip over at least 50% of its height, preferably at least 60% of its height, more preferably at least 70% of its height, more preferably at least 90% of its height.

In einem solchen Fall kann es vorteilhaft sein, dass der Schaumstoffstreifen im Bereich seiner Unterseite einen Steg aufweist, der die Schaumstoffsegmente miteinander verbindet und deren strukturellen Zusammenhalt gewährleistet.In such a case, it may be advantageous that the foam strip in the region of its underside has a web which connects the foam segments together and ensures their structural cohesion.

Ebenso ist es denkbar, dass sich die Schaumstoffsegmente im expandierten Zustand des Schaumstoffstreifens über 100 % seiner Höhe erstrecken. Dann ist eine maximale Entkopplung der Rückstellbewegungen der einzelnen Schaumstoffsegmente gewährleistet.It is also conceivable that the foam segments extend in the expanded state of the foam strip over 100% of its height. Then a maximum decoupling of the restoring movements of the individual foam segments is guaranteed.

Vorzugsweise sind die Einschnitte jeweils derart angeordnet, dass eine Mehrzahl von Schaumstoffsegmenten in Längsrichtung und in Querrichtung des Dichtbands jeweils vollständig von anderen Schaumstoffsegmenten umgeben ist. Dadurch wird die Dichtwirkung maximiert.Preferably, the incisions are each arranged such that a plurality of foam segments in the longitudinal direction and in the transverse direction of the sealing strip are each completely surrounded by other foam segments. This maximizes the sealing effect.

In einer besonders bevorzugten Ausführungsform erstreckt sich eine Mehrzahl von Einschnitten im Wesentlichen parallel zu den Seitenflächen.In a particularly preferred embodiment, a plurality of incisions extend substantially parallel to the side surfaces.

Zusätzlich kann sich eine Mehrzahl von Einschnitten im Wesentlichen senkrecht zu den Seitenflächen erstrecken, so dass ein in Draufsicht schachbrettartiges Muster von Schaumstoffsegmenten entsteht. Ebenso sind in Draufsicht rautenförmige Ausgestaltungen oder jede beliebige andere geometrische Ausgestaltung der Schaumstoffsegmente denkbar.In addition, a plurality of notches may extend substantially perpendicular to the side surfaces to form a checkered pattern of foam segments in plan view. Similarly, in plan view diamond-shaped configurations or any other geometric configuration of the foam segments are conceivable.

In einer bevorzugten Ausführungsform weist das Dichtband eine Trägerschicht auf, die an der Unterseite des Schaumstoffstreifens verhaftet ist. Diese Trägerschicht dient der Verbindung der einzelnen Schaumstoffsegmente.In a preferred embodiment, the sealing tape has a carrier layer which is adhered to the underside of the foam strip. This carrier layer serves to connect the individual foam segments.

Vorzugsweise ist die Trägerschicht dehnbar, wodurch ein Auseinanderziehen der Schaumstoffsegmente in Querrichtung des Dichtbands und damit eine Abdichtung von Fugen unterschiedlicher Tiefe möglich wird. Die Einschnitte zwischen den einzelnen Schaumstoffsegmenten können dabei zu Zwischenräumen auseinander gezogen werden, die aufgrund der eingeschlossenen Luft ebenfalls isolierend wirken.Preferably, the carrier layer is stretchable, whereby a pulling apart of the foam segments in the transverse direction of the sealing strip and thus a seal of joints of different depths is possible. The incisions between the individual foam segments can be pulled apart to spaces that also act insulating due to the trapped air.

Besonders einfach erfolgt die Anbringung des Dichtbands am abzudichtenden Bauteil, wenn die Trägerschicht beidseitig klebend ist oder als doppelseitiges Selbstklebeband ausgestaltet ist. Selbstverständlich sind auch andere Möglichkeiten der Anbringung des Dichtbands am Bauteil möglich, beispielsweise mittels nicht in die Trägerschicht integrierter Selbstklebestreifen oder mittels Pastös-, Flüssig- oder Schmelzklebstoffen.The attachment of the sealing tape to the component to be sealed is particularly simple if the carrier layer is adhesive on both sides or configured as a double-sided self-adhesive tape is. Of course, other ways of attaching the sealing tape on the component are possible, for example by means not integrated into the backing layer self-adhesive strips or pasties, liquid or hot melt adhesives.

Zur Platz sparenden Lagerung und zum Transport ist das erfindungsgemäße Dichtband vorzugsweise zu einer Rolle aufgewickelt. Weitere Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die Zeichnungen.

In den Zeichnungen sind Schaumstoffstreifen, Klebeschichten, Trägerschichten und Abdeckfolien teilweise in einem gewissen Abstand zueinander dargestellt, um die einzelnen Elemente, die das Dichtband bilden, klar voneinander abzuheben. In Wirklichkeit liegen diese Elemente jeweils eng aufeinander auf. Auch der Abstand des Dichtbands zum abzudichtenden Bauteil ist in der Realität nicht vorhanden.In the drawings, foam strips, adhesive layers, carrier layers and cover sheets are partially shown at a certain distance from each other to clearly distinguish the individual elements that form the sealing strip. In reality, these elements are closely related. Also, the distance of the sealing tape to be sealed component is not present in reality.

In Fig. 1 ist ein Dichtband dargestellt, das einen Schaumstoffstreifen 2 aufweist. Der Schaumstoffstreifen 2 hat im dargestellten Ausführungsbeispiel einen rechteckigen Querschnitt, es sind aber auch beliebige andere Formen denkbar. Der Schaumstoffstreifen 2 umfasst immer zwei Seitenflächen 4, eine Oberseite 6 und eine Unterseite 8.In Fig. 1 a sealing tape is shown having a foam strip 2. The foam strip 2 has in the illustrated embodiment has a rectangular cross section, but there are also any other shapes conceivable. The foam strip 2 always comprises two side surfaces 4, an upper side 6 and a lower side 8.

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 nach Kompression imprägniert sein. Das Raumgewicht derartiger Weichschaumstoffe liegt zwischen 20 und 200 kg/m3.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 delayed recovery after compression. The density of such flexible foams is between 20 and 200 kg / m 3 .

Üblicherweise erstreckt sich der Schaumstoffstreifen 2 in seiner Längsrichtung (Pfeil B) weiter als in seiner Querrichtung (Pfeil A), welche gleichzeitig die Funktionsrichtung des Dichtbands darstellt und zwischen den beiden Seitenflächen 4 verläuft. In der Praxis ist der Schaumstoffstreifen 2 meist so vorkomprimiert, dass er beim Entspannen vorzugsweise bis auf etwa das Fünf- bis Zehnfache seiner im vorkomprimierten Zustand eingenommenen Dicke expandieren kann, wovon aber häufig nur etwa die Hälfte ausgenutzt wird, um eine sichere Anlage an dem Gebäudeteil zu gewährleisten, das dem abzudichtenden Profilelement gegenüberliegt. Die Komprimierungs- und Entspannungsrichtung ist durch Pfeil C gekennzeichnet.Usually, the foam strip 2 extends in its longitudinal direction (arrow B) further than in its transverse direction (arrow A), which simultaneously represents the functional direction of the sealing strip and extends between the two side surfaces 4. In practice, the foam strip 2 is usually precompressed so that it can expand when relaxing preferably to about five to ten times its occupied in the pre-compressed state thickness, but often only about half is used to secure attachment to the building part to ensure, which is opposite to the profile element to be sealed. The compression and expansion direction is indicated by arrow C.

Der Schaumstoffstreifen 2 weist mehrere Schaumstoffsegmente 10 auf, die im vorliegenden Fall in Reihen und Spalten angeordnet sind. Diese Schaumstoffsegmente 10 werden durch Einschnitte 12 gebildet bzw. sind durch die Einschnitte 12 voneinander getrennt.The foam strip 2 has a plurality of foam segments 10, which are arranged in rows and columns in the present case. These foam segments 10 are formed by incisions 12 or are separated by the incisions 12 from each other.

Alle Einschnitte 12 erstrecken sich von der Oberseite 6 aus in den Schaumstoffstreifen 2 hinein. Die Einschnitte 12 und damit die Schaumstoffsegmente 10 erstrecken sich im expandiertem Zustand des Schaumstoffstreifens 2 über mindestens 50 % seiner Höhe, bevorzugt bis hin zu mindestens 90 % seiner Höhe. Dabei kann im Bereich der Unterseite 8 des Schaumstoffstreifens 2 ein Steg 14 verbleiben, der die Schaumstoffsegmente 10 miteinander verbindet. Dieser Steg 14 ist in Fig. 1 durch eine gepunktete Linie von den Schaumstoffsegmenten 10 getrennt, ist aber in der Realität einstückig mit diesen ausgebildet.All cuts 12 extend from the top 6 into the foam strip 2 inside. The incisions 12 and thus the foam segments 10 extend in the expanded state of the foam strip 2 over at least 50% of its height, preferably up to at least 90% of its height. In this case, in the region of the underside 8 of the foam strip 2, a web 14 remain, which connects the foam segments 10 with each other. This bridge 14 is in Fig. 1 separated by a dotted line from the foam segments 10, but is in reality formed integrally therewith.

Im vorliegenden Beispielsfall verlaufen die einen Einschnitte 12 im Wesentlichen parallel zu den Seitenflächen 4 des Schaumstoffstreifens 2 und die anderen Einschnitte 12 im Wesentlichen senkrecht zu den Seitenflächen 4 des Schaumstoffstreifens 2, wodurch sich in Draufsicht das schachbrettartige Muster der Schaumstoffsegmente 10 ergibt. Auf diese Weise ist immer eine Mehrzahl von Schaumstoffsegmenten 10, d.h. alle außer den am Rand des Dichtbands gelegenen Schaumstoffsegmenten 10, in Längsrichtung B und in Querrichtung A des Dichtbands jeweils vollständig von anderen Schaumstoffsegmenten 10 umgeben. Neben der dargestellten Form und Richtung der Einschnitte 12 sind viele andere Ausgestaltungen denkbar. So können die Einschnitte beispielsweise zickzackförmig durch das Dichtband verlaufen, wellenförmig oder auch in beliebiger anderer, vorzugsweise regelmäßiger Ausgestaltung. Dementsprechend kann die Form der einzelnen Schaumstoffsegmente 10 auch von der in Fig. 1 dargestellten Quaderform abweichen. Auch können die Einschnitte 12 von oben nach unten schräg verlaufen. Es ist nahezu jede dreidimensionale Ausgestaltung der Schaumstoffsegmente 10 denkbar.In the present example, the one incisions 12 extend substantially parallel to the side surfaces 4 of the foam strip 2 and the other incisions 12 substantially perpendicular to the side surfaces 4 of the foam strip 2, resulting in a checkered pattern of the foam segments 10 in plan view. In this way, a plurality of foam segments 10, ie all but the foam segments 10 located at the edge of the sealing tape, are completely surrounded by other foam segments 10 in the longitudinal direction B and in the transverse direction A of the sealing tape. In addition to the illustrated shape and direction of the incisions 12 many other embodiments are conceivable. Thus, the incisions may, for example, zigzag through the sealing strip, wavy or in any other, preferably regular design. Accordingly, the shape of the individual foam segments 10 may also be different from those in FIG Fig. 1 deviate shown cuboid shape. Also, the incisions 12 can be inclined from top to bottom. Almost every three-dimensional configuration of the foam segments 10 is conceivable.

Die Einschnitte 12 sind üblicherweise extrem schmal und durch Verdrängungsschnitte gebildet, durch die beim Schneiden der Einschnitte 12 in den Schaumstoffstreifen 2 kein Materialverlust auftritt. Ebenso ist es denkbar, die Einschnitte 12 durch Ausstanzen von Schaumstoffmaterial aus dem Schaumstoffstreifen 2 herzustellen, falls dies für bestimmte Anwendungsformen vorteilhaft sein sollte. In der Regel ist es aber bevorzugt, die Einschnitte 12 so schmal wie möglich zu gestalten und beim Einbringen der Einschnitte 12 möglichst wenig Material zu verlieren, um die Dichtwirkung des Dichtbands möglichst groß zu belassen.The cuts 12 are usually extremely narrow and formed by displacement cuts through which no material loss occurs when cutting the cuts 12 in the foam strip 2. It is also conceivable to produce the cuts 12 by punching out foam material from the foam strip 2, if this should be advantageous for certain applications. As a rule, however, it is preferred to make the cuts 12 as narrow as possible and to lose as little material as possible when introducing the cuts 12 in order to leave the sealing effect of the sealing strip as large as possible.

Zur Verhaftung des Dichtbands an einem abzudichtenden Bauteil 16 wie einem Rahmenprofil eines Fensters oder einer Tür (Fig. 2) ist an der Unterseite 8 des Schaumstoffstreifens 2 eine Klebeschicht 15 angeordnet. Üblicherweise ist diese Klebeschicht 15 mit einer hier nicht dargestellten Abdeckfolie überdeckt, welche vor dem Einsatz des Dichtbands abgezogen wird.For arresting the sealing tape on a component 16 to be sealed, such as a frame profile of a window or a door ( Fig. 2 ) An adhesive layer 15 is disposed on the underside 8 of the foam strip 2. Usually, this adhesive layer 15 is covered with a cover film, not shown here, which is withdrawn before the use of the sealing tape.

Mitunter kann in dieser Klebeschicht 15 noch ein Gittergewebe oder eine Trägerfolie, ein Vlies oder dergleichen zur Vergrößerung der Zugfestigkeit eingebettet sein. Der Ausdruck "Klebeschicht" soll daher auch Klebeschichten dieser Art umfassen.Occasionally, in this adhesive layer 15, a mesh fabric or a carrier film, a non-woven or the like may be embedded to increase the tensile strength. The term "adhesive layer" is therefore also intended to include adhesive layers of this type.

Vorzugsweise ist die Klebeschicht 15 als doppelseitiges Klebeband ausgebildet, welches eine feste haftende Verbindung zwischen dem Schaumstoffstreifen 2 und dem Bauteil 16 herstellt. Die Klebeschicht 15 kann auch durch eine Schicht eines handelsüblichen Klebers, der auf der Baustelle manuell aufzutragen ist, realisiert sein.Preferably, the adhesive layer 15 is formed as a double-sided adhesive tape, which produces a firm adhesive bond between the foam strip 2 and the component 16. The adhesive layer 15 can also be realized by a layer of a commercially available adhesive which is to be applied manually on the construction site.

In Fig. 2 ist der Einbauzustand des Dichtbands aus Fig. 1 dargestellt. Dabei ist ersichtlich, wie selbst große Unebenheiten des Mauerwerks 18 vom erfindungsgemäßen Dichtband aufgrund der Möglichkeit der unabhängigen Expansion der einzelnen Schaumstoffsegmente 10 ausgeglichen werden können und somit eine sichere Abdichtung und Anlage der Schaumstoffsegmente 10 am Mauerwerk 18 sichergestellt ist.In Fig. 2 is the installation state of the sealing band off Fig. 1 shown. It can be seen how even large unevenness of the masonry 18 of the sealing tape according to the invention due to the possibility of independent expansion of the individual foam segments 10 can be compensated and thus secure sealing and installation of the foam segments 10 on the masonry 18 is ensured.

Die in Fig. 3 dargestellte Ausführungsform des erfindungsgemäßen Dichtbands entspricht im Wesentlichen der Ausführungsform aus Fig. 1, enthält aber an der Unterseite 8 des Schaumstoffstreifens 2 eine Trägerschicht 20. Außerdem verlaufen die Einschnitte 12 über die gesamte Höhe des Schaumstoffstreifens 2, und somit werden die einzelnen Schaumstoffsegmente 10 lediglich durch die Trägerschicht 20 miteinander verbunden. Die Trägerschicht 20 ist am Schaumstoffstreifen 2 bzw. an den einzelnen Schaumstoffsegmenten 10 mittels Verklebung oder Laminierung verhaftet.In the Fig. 3 illustrated embodiment of the sealing tape according to the invention substantially corresponds to the embodiment of Fig. 1 but contains at the bottom 8 of the foam strip 2 a support layer 20. In addition, the incisions 12 extend over the entire height of the foam strip 2, and thus the individual foam segments 10 are connected only by the support layer 20 with each other. The carrier layer 20 is adhered to the foam strip 2 or to the individual foam segments 10 by means of gluing or lamination.

Vorzugsweise besteht die Trägerschicht 20 aus einem geschäumten Kunststoff, etwa aus Polyethylen, Polypropylen oder Zellkautschuk. Das Material der Trägerschicht 20 kann daneben auch ein Stoff, Vlies, eine Kunststofffolie (etwa aus Polyethylen, Polypropylen, Polyvinylchlorid oder Kautschuk), ein Gitternetz, ein Fadengelege oder ein Klebeband sein. Auch Leisten aus Kunststoff, Holz oder Metall sind denkbar, oder ein anderes Material, das für den genannten Einsatzzweck geeignet ist. Auch Kombinationen der oben genannten Materialien sind möglich. Die Dicke der Trägerschicht 20 beträgt zwischen 5 µm und 10 mm, vorzugsweise zwischen 20 µm und 3 mm.Preferably, the carrier layer 20 consists of a foamed plastic, such as polyethylene, polypropylene or cellular rubber. The material of the carrier layer 20 may also be a fabric, nonwoven, a plastic film (such as polyethylene, polypropylene, polyvinyl chloride or rubber), a mesh, a scrim or an adhesive tape. Also strips of plastic, wood or metal are conceivable, or another material that is suitable for the stated purpose. Combinations of the above materials are possible. The thickness of the carrier layer 20 is between 5 μm and 10 mm, preferably between 20 μm and 3 mm.

In einer besonders bevorzugten Ausführungsform ist die Trägerschicht 20 dehnbar ausgestaltet. Zusätzlich ist es von besonderem Vorteil, wenn die Trägerschicht 20 als doppelseitiges Selbstklebeband ausgestaltet ist. In diesem Fall ist die Trägerschicht 20 mit einer Abdeckfolie 22 kaschiert, die vor dem Einsatz des Dichtbands entfernt wird. Ebenso ist eine Verwendung einer beliebigen oben genannten Trägerschicht 20 in Kombination mit einer Klebeschicht 15, wie sie in Fig. 1 beschrieben wurde, denkbar.In a particularly preferred embodiment, the carrier layer 20 is made stretchable. In addition, it is of particular advantage if the carrier layer 20 is designed as a double-sided self-adhesive tape. In this case, the carrier layer 20 is laminated with a cover film 22, which is removed before the use of the sealing tape. Likewise, a use of any of the above-mentioned carrier layer 20 in combination with an adhesive layer 15, as shown in FIG Fig. 1 was described, conceivable.

Wenn die Trägerschicht 20 dehnbar gestaltet ist, können mit dem erfindungsgemäßen Dichtband unterschiedlich tiefe Fugen abgedichtet werden, indem das Dichtband auf die erforderliche Breite auseinander gezogen wird, wie aus Fig. 4 und Fig. 5 ersichtlich ist.If the carrier layer 20 is designed stretchable, can be sealed with the sealing tape according to the invention of different depth joints by the sealing tape is pulled apart to the required width, as from 4 and FIG. 5 is apparent.

Im normalen Zustand des Dichtbands liegen die Schaumstoffsegmente 10 eng aneinander an, siehe das Ausführungsbeispiel in einer Fuge geringer Tiefe in Fig. 4.In the normal state of the sealing band, the foam segments 10 are close to each other, see the embodiment in a deep groove in deep Fig. 4 ,

Durch das Auseinanderziehen des Schaumstoffstreifens 2 in Querrichtung A des Dichtbands werden die Einschnitte 12 zu Zwischenräumen 24 zwischen den einzelnen Schaumstoffsegmenten 10 verbreitert, wie es im Ausführungsbeispiel in der Fuge großer Tiefe in Fig. 5 dargestellt ist. Diese Zwischenräume 24 dienen aufgrund der darin gespeicherten Luft ebenfalls der Isolierung.By the pulling apart of the foam strip 2 in the transverse direction A of the sealing strip, the incisions 12 are broadened to spaces 24 between the individual foam segments 10, as in the embodiment in the joint of great depth in Fig. 5 is shown. These spaces 24 are also due to the stored air in the insulation.

Grundsätzlich kann das erfindungsgemäße Dichtband sowohl in Streifenform als auch als Dichtbandrolle hergestellt werden. Nach dem Abwickeln des Dichtbands von der Dichtbandrolle verbleibt in der Regel nur so viel Zeit für das Anbringen des Dichtbands an dem Bauteil 16 und das Einsetzen des Bauteils 16 in die dafür vorgesehene Fuge im Mauerwerk 18, bis die verzögerte Expansion der Schaumstoffsegmente 10 des Schaumstoffstreifens 2 das Dichtband zu groß zum Einfügen in die Öffnung macht. Da heutige Imprägnierungen eine Verzögerung der Expansion des Schaumstoffs um mehrere Stunden ermöglichen, stellt dies aber keine wesentliche Einschränkung dar. Wenn das Dichtband in Streifenform vorliegt, ist es ohnehin notwendig, den Streifen vor dem Einfügen in die Fuge zusammenzudrücken.In principle, the sealing strip according to the invention can be produced both in strip form and as a sealing strip roll. After unwinding of the sealing tape from the sealing tape roll usually leaves only so much time for attaching the sealing tape to the component 16 and the insertion of the component 16 in the space provided in the masonry 18, until the delayed expansion of the foam segments 10 of the foam strip. 2 the sealing tape makes it too big to insert into the opening. Since today's impregnations allow a delay of expansion of the foam by several hours, but this is not a significant limitation. If the sealing strip is in strip form, it is anyway necessary to compress the strip prior to insertion into the joint.

Grundsätzlich könnte das erfindungsgemäße Dichtband auch bereits vor dem Transport des abzudichtenden Bauteils 16 an diesem befestigt werden. Hierzu wäre es allerdings notwendig, dass das Dichtband durch eine Umhüllung (nicht dargestellt) an seiner Expansion gehindert wird. Dann müsste nach dem Einbau in die entsprechende Gebäudeöffnung vor Ort lediglich noch die Umhüllung geöffnet werden, woraufhin die Schaumstoffsegmente 10 des Schaumstoffstreifens 2 nach oben expandieren und die Abdichtung der Fuge gewährleisten.In principle, the sealing tape according to the invention could also be attached to it before the transport of the component 16 to be sealed. For this purpose, however, it would be necessary that the sealing tape is prevented by a sheath (not shown) in its expansion. Then, after installation in the corresponding building opening on site, only the covering would have to be opened, whereupon the foam segments 10 of the foam strip 2 expand upwards and ensure the sealing of the joint.
