Abstract

Als Zwischenträger für eine isolierende Gebäudeflächenbekleidung wird eine Kunststoffolie 4 vorgeschlagen, die gebildet ist aus parallelen, einander abwechselnden schwalbenschwanzförmigen Stegen 41 und Nuten 42. Auf der zur Untergrundbefestigung vorgesehenen Rückseite 4a dieser Kunststoffolie ist ein aufgeklebtes oder teilweise eingeschmolzenes grobmaschiges Netzvlies vorgesehene mit den Fäden 31 und 32. Ein solches Netzvlies überspannt die gesamte Rückseite 4a.A plastic film 4 is proposed as an intermediate support for insulating building surface cladding, which is formed from parallel, alternating, dovetail-shaped webs 41 and grooves 42 32. Such a mesh fleece spans the entire back 4a.

Description

Die Aufbringung von Bekleidungen an oder in Gebäuden in Form von Keramikplattenbelägen oder einem Putz ist vielfach prob­lematisch. Schäden in Form von Rissen oder Ablösen der Ver­kleidung vom Untergrund treten häufig dann auf, wenn unter­schiedliche Ausdehnungsspannungen im Wand- bzw. Bodenunter­grund und in der Verkleidung auftreten. Auch das Durchtreten von Feuchtigkeit durch die Verkleidung kann zu Schäden führen, beispielsweise bei Gips- oder Spanfaserplatten als Untergrund. Keramikplattenbeläge werden vielfach im soge­nannten Dünnschichtverfahren verlegt, bei dem ein geeigneter Kontaktkleber Verwendung findet. Es erweist sich in der Praxis schwierig, geeignete Kleber zu finden, die sowohl für den Untergrund als auch für die Rückseite einer Keramik­platte gleichermaßen geeignet sind. Die anzubindenden Werk­stoffe sind in der Praxis so unterschiedlich, daß der jeweilig verwendete Kleber immer ein Kompromiß bleibt.The application of clothing to or in buildings in the form of ceramic plate coverings or a plaster is often problematic. Damage in the form of cracks or detachment of the cladding from the subsurface often occurs when different expansion stresses occur in the wall or floor subsurface and in the cladding. The penetration of moisture through the cladding can also lead to damage, for example with gypsum or chipboard as a substrate. Ceramic plate coverings are often laid using the so-called thin-film process, which uses a suitable contact adhesive. It turns out to be difficult in practice to find suitable adhesives that are equally suitable for both the substrate and the back of a ceramic plate. The materials to be bonded are so different in practice that the adhesive used in each case always remains a compromise.

Bekannt ist aus der CH-PS 630 984 eine feuchtigkeitsundurch­lässige, isolierende Kunststoffolie für eine Gebäudeflächen­bekleidung mit zueinander paralleler wechselseitig offener, im Querschnitt schwalbenschwanzförmiger Profilierung. Da eine solche Kunststoffolie in Querrichtung zu der Profilierung dehnfähig ist, ermöglicht sie zur Breitenanpassung an den Untergrund einen Längenausgleich. Eine solche bekannte Kunst­stoffolie bildet mit ihren Stegen an einer Seite Befestigungs­rippen, die vorzugsweise im aushärtbaren Untergrund verklammernd eingebracht werden sollen. Die gebildeten nach außen offenen schwalbenschwanzförmigen Nuten dienen dabei zur Befriedigung ästhetischer Ansprüche sowie der Abführung von Feuchtigkeit in vertikaler Richtung bei entsprechendem Einbau.CH-PS 630 984 discloses a moisture-impermeable, insulating plastic film for a building surface covering with mutually parallel, mutually open, cross-sectionally dovetail-shaped profiling. Since such a plastic film is stretchable in the transverse direction to the profiling, it enables a length compensation for the width adjustment to the substrate. Such a known plastic film forms, with its webs, fastening ribs on one side, which should preferably be introduced in a clamped manner in the hardenable substrate. The formed outwardly open dovetail-shaped grooves serve to satisfy aesthetic requirements as well as the removal of moisture in the vertical direction with appropriate installation.

Kunststoffolien dieser Art lassen sich in der Regel nur dann in ausreichendem Maße in einem Mörtel oder Kleber an einer Wand befestigen, wenn die Kontaktschicht ausreichend dick ist, so daß der Mörtel oder der Kleber in die gebildeten schwalben­schwanzförmigen Fugen nahezu ausfüllend eingreift. Der die Fugen ausfüllende Mörtel bzw. der aushärtende Kleber beschränkt die Dehnfähigkeit einer solchen eingebauten Kunststoffolie quer zur Richtung der Stege.Plastic films of this type can generally only be sufficiently attached to a wall in a mortar or adhesive if the contact layer is sufficiently thick so that the mortar or adhesive engages almost completely in the dovetail-shaped joints formed. The mortar filling the joints or the hardening adhesive limits the elasticity of such a built-in plastic film transverse to the direction of the webs.

Die Aufgabe der Erfindung besteht darin, eine Kunststoffolie für eine isolierende Gebäudeflächenbekleidung, mit zueinander paralleler wechselseitig offener, im Querschnitt schwalben­schwanzförmiger Profilierung so vorzubereiten, daß sie zur Erstellung von feuchtigkeitsundurchlässigen Aufbauten einge­setzt werden kann, in denen vom Untergrund oder der Verklei­dung herrührende Spannungen weitgehend ausgeglichen werden können, und bei der die Auswahl der einzusetzenden Verbindungs­mittel wie Kleber oder Mörtel erleichtert wird.The object of the invention is to prepare a plastic film for insulating building surface cladding with mutually parallel mutually open, cross-section dovetail-shaped so that it can be used to create moisture-impermeable structures in which tensions originating from the substrate or cladding are largely compensated can, and in which the selection of the connecting means to be used such as adhesive or mortar is facilitated.

Gelöst wird die Erfindungsaufgabe mit einer solchen Kunst­stoffolie, die dadurch gekennzeichnet ist, daß auf einer Seite der Kunststoffolie ein grobmaschiges Netzvlies fest aufgebracht ist. Dabei können die Fäden des Netzvlieses teilwiese vorstehend angeordnet sein. Vorzugsweise ist das Netzvlies in den die gebäudeseitige Anlagefläche bildenden Abschnitten eingepreßt bzw. teilweise eingeschmolzen.The object of the invention is achieved with such a plastic film, which is characterized in that a coarse-mesh nonwoven is firmly attached to one side of the plastic film. The threads of the nonwoven fabric can be arranged partially above. The net fleece is preferably pressed or partially melted into the sections forming the contact surface on the building side.

Eine solche erfindungsgemäße Kunststoffolie wird mit der mit dem Netzvlies versehenen Folienseite auf dem Gebäudeuntergrund mit einer Kontaktschicht angeklebt. Die Fäden des Netzvlieses dienen dabei als Verklammerungselemente, wodurch die Kontakt­verbindung zwischen dem Untergrund und der Kunststoffolie stark verbessert wird. Das Netzvlies verhindert dabei, daß der Kleber oder der Mörtel in nennenswertem Maße in die zur Gebäudeseite offenen Nuten eindringt. Die auf diese Weise auf dem Untergrund angebrachte Kunststoffolie kann nunmehr als Träger für Verklei­dungen, wie beispielsweise Keramikplattenbelägen, dienen, die mit einem Mörtel oder Kleber in größerer Schichtdicke befestigt werden. Von der Vorderseite der Kunststoffolie her wird dabei der Mörtel vollflächig und die Fugen ausfüllend aufgebracht. Keramikplatten oder Putzmörtel werden dann in bekannter Weise darauf aufgebracht. Die Kunststoffolie wird insbesondere dann zur Flächenbekleidung eingesetzt, wenn Spannung zwischen Untergrund und Bekleidung auszugleichen sind, beispielsweise im Bereich von Wänden oder Fußböden, in denen Heizungseinrich­tungen eingebaut sind. Da von der Rückseite her die Nuten der Kunststoffolie offen bleiben, bleibt diese als Zwischenträger eingesetzte Folie quer zu den Stegen in ausreichendem Maße dehnfähig und ist so in der Lage, auftretende Spannungen zwischen Untergrund und äußerer Verkleidung in weitem Maße auszugleichen.Such a plastic film according to the invention is adhesively bonded to the base of the building with a contact layer using the film side provided with the nonwoven. The threads of the nonwoven serve as clamping elements, which greatly improves the contact connection between the substrate and the plastic film. The mesh fleece prevents the adhesive or mortar from penetrating to any appreciable extent into the grooves open on the building side. The plastic film attached in this way to the substrate can now serve as a carrier for claddings, such as ceramic plate coverings, which are fastened with a mortar or adhesive in a thicker layer. From the front of the plastic film, the mortar is applied over the entire surface and the joints are filled. Ceramic plates or plastering mortar are then applied to it in a known manner. The plastic film is used in particular for surface clothing when tension between the surface and clothing has to be balanced, for example in the area of walls or floors in which heating devices are installed. Since the grooves of the plastic film remain open from the rear, this film, which is used as an intermediate carrier, remains sufficiently stretchable transversely to the webs and is thus able to largely compensate for any tension that occurs between the substrate and the outer cladding.

Zur Erfindung gehört auch der Vorschlag, am Ende und/oder am Anfang einer solchen Kunststoffolie einen unprofilierten glatten Überlappungsabschnitte vorzusehen, der das Verlegen solcher Folien erleichtert.The invention also includes the proposal of an unprofiled at the end and / or at the beginning of such a plastic film provide smooth overlap sections, which facilitates the laying of such films.

Anhand eines im Prinzip abgebildeten Ausführungsbeispieles wird die Erfindung im folgenden näher erläutert. Es zeigen:

  • Fig. 1 einen Querschnitt durch den Aufbau einer mit der erfindungsgemäßen Kunststoffolie und darauf aufgebrachten Keramikplatten verkleideten Wand,
  • Fig. 2 eine vergrößerte Teilansichtsdarstellung des Endes einer eingesetzten Kunststoffolie,
  • Fig. 3 einen Schnitt nach der Linie I-I in Fig. 2
    und
  • Fig. 4 einen Schnitt nach der Linie II-II in Fig. 2.
The invention is explained in more detail below on the basis of an exemplary embodiment depicted in principle. Show it:
  • 1 shows a cross section through the construction of a wall clad with the plastic film according to the invention and ceramic plates applied thereon,
  • 2 is an enlarged partial view of the end of an inserted plastic film,
  • 3 shows a section along line II in FIG. 2
    and
  • 4 shows a section along the line II-II in FIG. 2.

Die in den Figuren dargestellte Kunststoffolie 4 ist, wie insbesondere aus Figur 3 ersichtlich, profiliert. Das Profil wird gebildet aus parallelen einander abwechselnden schwalben­schwanzförmigen Stegen 41 und Nuten 42. Die zur Untergrund­befestigung dienende Rückseite trägt die Ziffer 4a, die zur Verkleidungsseite gerichtete Vorderseite trägt die Ziffer 4b. An der Rückseite 4a sind Verklammerungselemente vorgesehen in Form eines aufgeklebten oder teilweise eingeschmolzenen grobmaschigen Netzvlieses 3. Die Fäden dieses Netzvlieses 3 tragen die Ziffern 31 und 32. Ein solches Netzvlies überspannt die gesamte Rückseite 4a. Lediglich im oberen und unteren Bereich, in dem ein flacher Überlappungsabschnitt 43 ausgebil­det ist, kann dieses Vlies entfallen.The plastic film 4 shown in the figures is profiled, as can be seen particularly in FIG. The profile is formed from parallel, mutually alternating dovetail-shaped webs 41 and grooves 42. The back, which is used to fasten the subsurface, bears the number 4a, the front facing the cladding side bears the number 4b. Clamping elements are provided on the rear side 4a in the form of a glued-on or partially melted-in coarse-mesh nonwoven fabric 3. The threads of this nonwoven fabric 3 bear the numbers 31 and 32. Such a nonwoven fabric spans the entire rear side 4a. This fleece can only be omitted in the upper and lower region, in which a flat overlap section 43 is formed.

Aufgrund der gewählten Profilierungen ist eine solche Kunst­stoffolie in Querrichtung zu den Stegen 41 dehnfähig. Die Vorderseite 4b der Kunststoffolie ist bezüglich der einzelnen Flächen besonders glatt, da in bestimmten Anwendungsfällen nach Möglichkeit die Anhaftung einer aufzubringenden Spachtelschicht vermieden werden soll.Due to the selected profiles, such a plastic film is stretchable in the transverse direction to the webs 41. The front 4b of the plastic film is with respect to the individual Surfaces particularly smooth, since in certain applications the adhesion of a filler layer to be applied should be avoided if possible.

Bei dem in Figur 1 dargestellten Wandaufbau ist auf dem Wanduntergrund 1, beispielsweise aus Gipsplatten oder Span­faserplatten eine Kleberschicht 2 aufgebracht. Auf diese Schicht 2 werden Kunststoffolien 4 in entsprechender Größe und Überdeckung aufgeklebt. Die Überlappungsabschnitte können dabei noch zusätzlich durch Verklebung oder Verschweißung abge­dichtet werden. Das auf der Rückseite 4a der Kunststoffolie 4 vorgesehene Netzvlies 3 verklammert sich mit seinen Fäden 31 und 32 in der Kleberschicht 2 und ist damit fest mit dem Wand­untergrund 1 verbunden. Auf die Vorderseite 4a wird ein Spach­telmörtel 5 aufgebracht, der in die Nuten eindringt und sich dort aufgrund der Hinterschneidungen verklammert. Die gebildete glatt gespachtelte Fläche 5 bildet dann den Untergrund für die aufzubringende Bekleidung, die im Ausführungsbeispiel ein Plattenbelag aus Keramikplatten 7 ist. Zur Befestigung dieser Keramikplatten 7 wird auf die Spachtelfläche 5 der geeignete Kleber 6 aufgebracht. Die Keramikplatten 7 werden dann im bekannten Dünnbettschichtverfahren aufgebracht.In the wall construction shown in FIG. 1, an adhesive layer 2 is applied to the wall base 1, for example made of plasterboard or chipboard. Plastic films 4 of appropriate size and covering are glued onto this layer 2. The overlapping sections can also be sealed by gluing or welding. The mesh fleece 3 provided on the rear side 4a of the plastic film 4 clamps with its threads 31 and 32 in the adhesive layer 2 and is thus firmly connected to the wall base 1. A leveling mortar 5 is applied to the front side 4a, which penetrates into the grooves and clings there due to the undercuts. The smooth, leveled surface 5 then forms the base for the clothing to be applied, which in the exemplary embodiment is a plate covering made of ceramic plates 7. To fasten these ceramic plates 7, the suitable adhesive 6 is applied to the spatula surface 5. The ceramic plates 7 are then applied in the known thin-bed method.

Ist ein Putzmörtel aufzubringen, so kann dieser direkt gege­benenfalls mit einem Unterputz auf der Vorderseite der Folie oder auf der gespachtelten Fläche 5 aufgebracht werden. Dabei kann es bei direkter Aufbringung zweckmäßig sein, auch an der Vorderseite der Folie zusätzliche Verklammerungselemente in Form eines grobmaschigen Netzvlieses vorzusehen.If a plastering mortar is to be applied, it can be applied directly with a plaster on the front of the film or on the leveled surface 5, if necessary. In the case of direct application, it may also be expedient to provide additional clamping elements in the form of a coarse-mesh nonwoven also on the front of the film.
