Description

Die Erfindung betrifft eine Dichtleiste für die Überbrückung von Fugen zwischen zwei Bauelementen, insbesondere zwischen einem Fensterrahmen und einer Putz- und Mauerschicht, bestehend aus einem leistenförmigen Trägerelement aus Kunststoff und einem darauf angebrachten, elastischen Dichtungsband.The invention relates to a sealing strip for the bridging of joints between two components, in particular between a window frame and a plaster and wall layer consisting of a strip-shaped carrier element made of plastic and an elastic sealing strip attached thereto.

Bei Dichtleisten des Standes der Technik besteht das elastische Dichtungsband in den meisten Fällen aus einem Schaumklebeband mit einer Stärke von etwa 3 mm. Beispiele hierzu zeigen DE 20 2008 000 916 U1 oder DE 20 2007 000 895 U1 . In der Praxis hat sich herausgestellt, dass derartige, aus geschäumtem Kunststoff hergestellte Dichtungsbänder nur Bewegungen in sehr engen Grenzen aufnehmen können; die Bewegungsaufnahme verschlechtert sich im übrigen mit dem Alter der Schaumklebebänder. Das führt dann dazu, dass die Fuge zwischen den beiden Bauelementen nicht mehr überbrückt wird, so dass sich ein Öffnungsschlitz bildet, was beispielsweise bei Fensterrahmen zu Wärmebrücken führt, weil das Schaumklebeband von der gegenüberliegenden Fläche abreißt.In prior art sealing strips, the elastic sealing strip consists in most cases of a foam adhesive tape having a thickness of about 3 mm. Examples show this DE 20 2008 000 916 U1 or DE 20 2007 000 895 U1 , In practice it has been found that such sealing strips made of foamed plastic can only absorb movements within very narrow limits; Incidentally, the movement absorption deteriorates with the age of the foam adhesive tapes. This then leads to the fact that the gap between the two components is no longer bridged, so that forms an opening slit, which leads, for example in window frames to thermal bridges, because the foam adhesive tape tears off from the opposite surface.

Der Erfindung liegt die Aufgabe zugrunde, eine Dichtleiste der eingangs umrissenen Gattung so auszubilden, dass das elastische Dichtungsband eine erheblich bessere Bewegungsaufnahmefähigkeit hat, so dass die Fuge auch bei größeren Relativbewegungen zwischen den beiden Bauelementen dicht geschlossen bleibt.The invention has the object of providing a sealing strip of the initially outlined genus in such a way that the elastic sealing strip has a much better ability to absorb movement, so that the joint remains tightly closed even with larger relative movements between the two components.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, dass das elastische Dichtungsband vollständig und restlos aus einer Klebstoffmasse, z. B. einem geschäumten Gelklebeband besteht.To solve this problem is provided according to the invention that the elastic sealing strip completely and completely from an adhesive composition, for. B. consists of a foamed gel tape.

Dabei ist es von Vorteil, wenn das Dichtungsband aus einem Acrylat-Klebstoff besteht.It is advantageous if the sealing strip consists of an acrylate adhesive.

Mit der Erfindung wird der Vorteil erzielt, dass ein derartiges Dichtungsband nicht nur eine höhere Elastizität und Flexibilität als bisher verwendete Schaumklebebänder hat, sondern auch mit größeren Dicken bis hin zu 5 mm oder gar mehr hergestellt werden kann. Ein derartiges Dichtungsband ist zwar in der Herstellung etwas teurer als bisherige Schaumklebebänder, was jedoch dadurch wettgemacht wird, dass es durch und durch aus einem Klebstoff besteht, der alterungsbeständig ist und unmittelbar und ohne Zwischenkleberschichten auf dem Trägerelement dauerhaft fixiert werden kann.With the invention, the advantage is achieved that such a sealing strip not only has a higher elasticity and flexibility than previously used foam adhesive tapes, but also with larger thicknesses up to 5 mm or even more can be produced. Although such a sealing strip is somewhat more expensive to manufacture than previous foam adhesive tapes, this is made up by the fact that it consists entirely of an adhesive which is resistant to aging and can be permanently fixed directly on the carrier element without intermediate adhesive layers.

Um zu vermeiden, dass die Dichtleisten aneinander festkleben, z. B. in einer Verpackung, in der mehrere Dichtleisten untergebracht sind, ist es von Vorteil, wenn das Dichtungsband auf wenigstens einer seiner freiliegenden Stirnseiten mit einem nichthaftenden Material beschichtet ist.To avoid that the sealing strips stick together, z. B. in a package in which a plurality of sealing strips are housed, it is advantageous if the sealing strip is coated on at least one of its exposed end faces with a non-adhesive material.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Schutzansprüchen und aus der folgenden Beschreibung von zwei Ausführungsbeispielen, die in der Zeichnung dargestellt sind. Es zeigen:

Figur 1
einen Querschnitt durch eine Dichtleiste des Standes der Technik,
Figur 2
einen Querschnitt durch eine Dichtleiste gemäß der Erfindung und
Figur 3
eine Variante der Figur 2.
Further features and advantages of the invention will become apparent from the claims and from the following description of two embodiments, which are illustrated in the drawing. Show it:
FIG. 1
a cross section through a sealing strip of the prior art,
FIG. 2
a cross section through a sealing strip according to the invention and
FIG. 3
a variant of FIG. 2 ,

Die in den Figuren 1 und 2 gezeigte Dichtleiste 10 dient in beiden Fällen für die Überbrückung von Fugen zwischen zwei nicht weiter dargestellten Bauelementen, beispielsweise einem Fensterrahmen und einer Mauerlaibung.The in the Figures 1 and 2 shown sealing strip 10 is used in both cases for the bridging of joints between two components not shown, such as a window frame and a wall reveal.

Wie die Figur 1 zeigt, besteht die bekannte Dichtleiste 10 aus einem Trägerelement 12 aus Kunststoff und einem darauf angebrachten Dichtungsband 14. Das Trägerelement 12 ist hier als eine im Querschnitt U-förmige Profilleiste 24 aus Kunststoff ausgebildet, die mit ihren Schenkeln 16 in ein nicht gezeigtes Wandelement eingeputzt werden kann.As the FIG. 1 shows, the known sealing strip 10 consists of a support member 12 made of plastic and a sealing tape 14 mounted thereon. The support member 12 is formed here as a cross-sectionally U-shaped profile strip 24 made of plastic, which are plastered with their legs 16 in a wall element not shown can.

Das elastische Dichtungsband 14 des Standes der Technik ist aus einem Schaumkunststoff 18 hergestellt und mittels einer Kleberschicht 20 auf der Basisfläche des Trägerelementes 12 befestigt. Die nach außen weisende Seite des Dichtungsbandes 14 ist durch ein abziehbares Schutzband 22 abgedeckt.The elastic sealing tape 14 of the prior art is made of a foam plastic 18 and by means of an adhesive layer 20 on the base surface of the support element 12th attached. The outwardly facing side of the sealing strip 14 is covered by a peelable protective tape 22.

Wie Figur 2 zeigt, hat die Dichtleiste 10 gemäß der Erfindung grundsätzlich einen vergleichbaren Aufbau wie diejenige der Figur 1. Das Trägerelement 12 ist auch hier im Querschnitt als U-förmige Profilleiste 24 ausgebildet, wobei die Enden der beiden Schenkel 16 ein Tannenbaumprofil 26 haben. An einer Seite der Profilleiste 24 ist eine Dichtlippe 28 angeformt.As FIG. 2 shows, the sealing strip 10 according to the invention in principle has a similar structure as that of FIG. 1 , The support member 12 is also formed here in cross-section as a U-shaped profile strip 24, wherein the ends of the two legs 16 have a Christmas tree profile 26. On one side of the profile strip 24, a sealing lip 28 is formed.

Selbstverständlich besteht die Möglichkeit, das Trägerelement 12 in einer anderen Form auszubilden; das Tannenbaumprofil 26 und die Dichtlippe 28 sind nicht Teil der Erfindung.Of course, it is possible to form the carrier element 12 in another form; the Christmas tree profile 26 and the sealing lip 28 are not part of the invention.

Wesentlich für die Erfindung ist, dass das Dichtungsband 14 nicht aus einem Schaumkunststoff hergestellt ist, sondern über die gesamte Dicke, die auch 5 mm oder gar mehr betragen kann, in toto aus einer Klebstoffmasse 30, einem geschäumten Klebstoff oder einem Gelklebeband besteht. Als Klebstoffmasse 30 hat sich ein Acrylat-Klebstoff bewährt.Essential for the invention is that the sealing strip 14 is not made of a foam plastic, but over the entire thickness, which may also be 5 mm or even more, in toto from an adhesive composition 30, a foamed adhesive or a gel adhesive tape. As adhesive composition 30, an acrylate adhesive has been proven.

Auch bei dem in dieser Weise ausgebildeten Dichtungsband 14 ist die nach außen weisende Oberseite durch ein abziehbares Schutzband 22 abgedeckt. Da das Dichtungsband 14 durch und durch klebende Eigenschaften hat, erübrigt sich die beim Stand der Technik gemäß Figur 1 erforderliche Kleberschicht 20, weil die Klebstoffmasse 30 unmittelbar haftend auf dem Trägerelement 12 fixiert werden kann.Even with the sealing strip 14 formed in this way, the outwardly facing upper side is covered by a peelable protective tape 22. Since the sealing tape 14 has through and through adhesive properties, which is unnecessary in the prior art according to FIG. 1 required adhesive layer 20, because the adhesive mass 30 can be fixed directly adhering to the support member 12.

Das Dichtungsband 14 ist auf seiner freiliegenden Stirnseite 32 mit einem nichthaftenden Material beschichtet, beispielsweise einem Pulver, Papier oder Lack, so dass z. B. in einer Verpackung aneinanderliegende Dichtleisten 10 nicht miteinander verkleben können. Dabei ist es vorteilhaft, das nicht haftende Material so zu wählen, dass es nach dem Einbau der Dichtleiste 10 überstrichen werden kann, beispielsweise mit einer Farbe.The sealing tape 14 is coated on its exposed end face 32 with a non-adhesive material, such as a powder, paper or paint, so that z. B. in a package adjacent sealing strips 10 can not stick together. It is advantageous to select the non-adherent material so that it can be painted over after installation of the sealing strip 10, for example, with a color.

In der Variante der Figur 3 ist einer der beiden Schenkel 16 der Profilleiste 24 als Einputzschenkel 16' ausgebildet. Bei dem auch hier vollständig aus einer Klebstoffmasse 30 bestehenden Dichtungsband 14 sind beide Stirnseiten 32 mit nichthaftendem Material beschichtet, wobei eine der beiden Stirnseiten eine Schrägfläche 32' ist, die nach außen divergiert.In the variant of FIG. 3 one of the two legs 16 of the profile strip 24 is formed as Einputzschenkel 16 '. In the case of the sealing strip 14, which is also entirely composed of an adhesive compound 30, both end faces 32 are coated with non-adhesive material, one of the two end faces being an inclined surface 32 'which diverges outwards.
