Abstract

The invention relates to a support and/or drainage plate made of a foil-like plastic material, for use with a plate-lined floor structure or a wall so as to create a space between the ground and the surface lining to be applied onto the foil-like plate. The structure of the plate is such that cavities are created by means of, on the one side, projections extending substantially in one direction and, on the other side, raised areas at the same level between which chambers are embodied for receiving a hardening contact medium, such as mortar or adhesive, which forms a contact layer with the surface lining to be applied. According to the invention the structure consists of projections (N1, N2) or (S1, S2) which extend in at least two directions and intersect. The resulting chambers (M1) are delimited in their circumference by the projections (S1, S2), which are open towards the other side of the plate.

Description

Die Erfindung betrifft eine Trägerplatte nach dem Oberbegriff des Anspruchs 1.The invention relates to a carrier plate according to the preamble of claim 1.

Die Aufbringung von Bekleidungen, insbesondere Keramikplatten, im Inneren oder außen an Gebäuden ist vielfach problematisch. Aufgrund unterschiedlicher Wärmeausdehnungen und den damit verbundenen Spannungen können Risse in der Bekleidung entstehen, auch das Ablösen von Bekleidungsplatten ist aufgrund solcher Spannungszustände feststellbar. Insbesondere Keramikplattenbelege werden vielfach im sogenannten Dünnbettverfahren verlegt, bei dem ein geeigneter Kontaktmörtel Verwendung findet. Dabei ergeben sich Schwierigkeiten in den unterschiedlichen Haftungsbedingungen an der Unterseite einer solchen Platte bzw. an dem Untergrund. Zusätzlich werden solche Problematiken auch noch durch Anforderungen an die Dichtheit des Aufbaues beeinflußt.The application of clothing, especially ceramic tiles, inside or outside buildings is often problematic. Due to different thermal expansions and the associated stresses can cause cracks in clothing, and the detachment of cladding panels can be determined due to such stress states. In particular ceramic plate slips are often laid in the so-called thin bed process, in which a suitable contact mortar is used. This results in difficulties in the different adhesion conditions on the underside of such a plate or on the ground. In addition, such problems are also influenced by requirements for the tightness of the structure.

Um in solchen Anwendungsfällen auftretende Spannungsunterschiede abzubauen bzw. den Aufbau bezüglich der auftretenden Spannung vom Untergrund zu entkoppeln, sind bereits Trägerplatten aus folienartigem Kunststoff vorgeschlagen worden. Eine entsprechende Platte ist aus der DE 37 01 414 A1 bekannt. Durch abwechselnd nach beiden Plattenseiten hin offenen schwalbenschwanzförmigen Nuten ist dabei eine Trägerplatte gebildet, die sich bei Druck- und Zugbeanspruchung quer zum Verlauf dieser Nuten bewegen läßt.In order to reduce voltage differences occurring in such applications or to decouple the structure with respect to the voltage occurring from the ground, support plates made of film-like plastic have already been proposed. A corresponding plate is from the DE 37 01 414 A1 known. By alternately on both sides of the plate open dovetailed grooves while a support plate is formed, which can be moved transversely to the course of these grooves in compressive and tensile stress.

Wird eine solche Trägerplatte am Untergrund befestigt und darauf eine Bekleidung mit entsprechendem Kontaktmittel aufgebracht, so kann dann ein Spannungsausgleich in dieser angegebenen Richtung herbeigeführt werden, wenn sichergestellt ist, daß sich die gebildeten Nuten nicht mit dem Kontaktmittel, beispielsweise einem Mörtel, vollständig ausfüllen. Um dieses Ausfüllen zu verhindern, ist bereits vorgeschlagen worden, solche Platten an einer Seite mit netzartigen Textilien oder einem Vlies zu versehen, wodurch eine erhöhte Kontaktfähigkeit erreicht wird. Solche Trägerplatten sind aber nur in einer Richtung dehnfähig bzw. zusammendrückbar. Vielfach ist daher mit solchen Platten ein notwendiger Spannungsabbau nicht möglich.If such a support plate attached to the ground and applied to a clothing with an appropriate contact means, then a voltage compensation in this direction can be brought about, if it is ensured that the grooves formed do not fill completely with the contact means, such as a mortar. In order to prevent this filling, it has already been proposed to provide such panels on one side with reticulated textiles or a fleece, whereby an increased contact ability is achieved. However, such carrier plates are only extensible or compressible in one direction. In many cases, therefore, a necessary stress relief is not possible with such plates.

Die Druckschrift DE-U-298 07 258 offenbart eine Drainageplatte aus folienartigem Kunststoff für einen plattenbekleideten Boden- oder einen Wandaufbau zum Erzielen einer Drainage sowie einer Entkopplung eines Bodenaufbaus. Die Drainageplatte umfasst eine Strukturierung zum Ausbilden von Vertiefungen durch sich kreuzende Ausprägungen auf einer Seite und auf der anderen Seite niveaugleiche, erhabene Bereiche, zwischen denen Kammern zur Aufnahme eines zur Ausbildung einer Mörtelschicht mit einer darauf aufzubringenden Flächenbekleidung gebildet sind. An der Oberseite und/oder an der Unterseite der Drainageplatte kann insbesondere für die Verwendung im Wundbereich zur Verbesserung der Verklammerungsfähigkeit mit einem Belag oder dem Untergrund wasserdurchlässiges Vlies oder netzartiges Textilgewebe vorgesehen sein.The publication DE-U-298 07 258 discloses a drainage plate of sheet-like plastic for a plate-clad floor or wall construction for achieving drainage and decoupling of a floor structure. The drainage plate comprises a structure for forming recesses by intersecting forms on one side and on the other side level, raised areas, between which chambers are formed for receiving a mortar layer with an applied surface to be applied thereto. On the upper side and / or on the underside of the drainage plate, water-permeable nonwoven or reticulated textile fabric can be provided, in particular for use in the wound area, to improve the ability to interlock with a covering or the substrate.

Die Aufgabe der Erfindung besteht darin, eine Trägerplatte aus folienartigem Kunststoff für den plattenbekleideten Bodenaufbau oder eine entsprechende Wand vorzuschlagen, mit der in optimierender Weise die auftretenden unterschiedlichen Ausdehnungen zwischen Untergrund und Bekleidung und daraus möglicherweise resultierenden Spannungen abgebaut bzw. entkoppelt werden.The object of the invention is to propose a support plate of foil-like plastic for the plate-covered floor structure or a corresponding wall, with the optimizing manner occurring or decoupled the occurring different expansions between the ground and clothing and possibly resulting voltages.

Gelöst wird diese Erfindungsaufgabe mit einer Trägerplatte mit den Merkmalen des Anspruchs 1. Eine solche erfindungsgemäße Platte aus folienartigem Kunststoff weist eine sich kreuzende Strukturierung auf, bei der auf einer Plattenseite sich kreuzende Ausprägungen ausgebildet sind, die jeweils umfänglich geschlossene Kammern bilden. Auf der anderen Seite bilden diese Ausprägungen Nuten, so daß die andere Plattenseite durch sich kreuzende Nutenscharen bestimmt ist. In der Regel wird die Plattenseite mit den Ausprägrungren und den damit gebildeten Kammern dem Kleber oder Mörtel aufnehmen, wodurch ein inniger Verbund mit der Kleber- oder Mörtelschicht entsteht. In dieser Schicht können sich bei vorhandenen Spannungen wiederum an den zahlreichen Kanten und Ecken der Ausprägungen Trennflächenscharen ausbilden, die dem Spannungsabbau dienen. Die folienartige Platte selbst ist aufgrund der vorgeschlagenen Strukturierung und ihres Materials in beiden Seiten ihrer Erstrekkungsebene zumindest in geringem ausreichendem Maße dehnfähig bzw. zusammenschiebbar, so daß Spannungsdifferenzen aus dem Untergrund und der Bekleidung aufgenommen werden können. Bei der erfindungsgemäß strukturierten Trägerplatte aus einer Kunststoffolie wird bevorzugt vorgeschlagen, die zu einer Seite offenen Ausprägungen mit Nuten mit einem im wesentlichen rechteckigen Querschnitt auszubilden, so daß sich kreuzende, im Querschnitt etwa rechteckige Nutenscharen vorhanden sind. Dabei ist es zweckmäßig, zwei Nutenscharen in gleichmäßiger Flächenverteilung in zueinander senkrechter Anordnung auszubilden.This invention task is solved with a support plate with the features of claim 1. Such a plate of sheet-like plastic according to the invention has an intersecting structuring, in which on a plate side intersecting forms are formed, each forming circumferentially closed chambers. On the other hand, these forms grooves, so that the other side of the plate is determined by intersecting Nutenscharen. In general, the panel side with the Ausprägrungren and the chambers formed therewith will take up the adhesive or mortar, whereby an intimate bond with the adhesive - or mortar layer. In this layer, in the case of existing stresses, it is again possible to form separation surface shares at the numerous edges and corners of the forms, which reduce the stress serve. The sheet-like plate itself is due to the proposed structure and their material in both sides of their Erstrekkungsebene stretchable or collapsible at least to a small extent sufficient, so that voltage differences from the ground and the clothing can be accommodated. In the case of the carrier plate of a plastic film structured in accordance with the invention, it is preferably proposed to form the forms open to one side with grooves having a substantially rectangular cross section, so that there are intersecting grooves which are approximately rectangular in cross section. It is expedient to form two Nutenscharen in a uniform area distribution in mutually perpendicular arrangement.

Die zumindest in zwei unterschiedlichen, sich kreuzenden Richtungen verlaufenden Ausprägungen bilden an einer Plattenseite Kammern zur Aufnahme von Mörtel zum Befestigen des eigentlichen Bekleidungsbelages. Anstelle von zwei in unterschiedlichen Richtungen verlaufenden Ausprägungen können auch drei oder mehr vorgesehen sein.The characteristics extending at least in two different, intersecting directions form chambers for receiving mortar for fastening the actual clothing covering on one side of the plate. Instead of two variants running in different directions, three or more may also be provided.

Die Ausprägungen lassen sich beispielsweise durch Vakuumformen einer Kunststoffolie ausbilden. Dabei kann vorgesehen sein, daß der Hinterschnitt voll umfänglich entlang den einer Kammer begrenzenden Ausprägungen angeordnet ist. Es kann auch vorgesehen sein, daß lediglich Abschnitte der angrenzenden Ausprägungen jeweils einen Hinterschnitt aufweisen, wie dies beispielsweise bei sich kreuzenden Nutenscharen durch jeweils bestimmte Abschnitte einer Kante einer solchen Kammer bildenden Ausprägung realisiert sein kann. Zur Ausbildung einer solchen Hinterschneidung können auch die Kreuzungspunkte der sich kreuzenden Ausprägungen, beispielsweise der sich kreuzenden Nuten, vorgesehen sein, wobei eine solche Hinterschneidung teilweise der einen Nutenschar und teilweise der anderen Nutenschar zugeordnet werden kann.The forms can be formed for example by vacuum forming a plastic film. It can be provided that the undercut is arranged fully circumferentially along the forms limiting a chamber. It can also be provided that only sections of the adjacent forms each have an undercut, as can be realized, for example, in intersecting Nutenscharen by each particular sections of an edge of such a chamber forming expression. To form such an undercut, the crossing points of the intersecting forms, for example, the intersecting grooves, can be provided, wherein such an undercut can be assigned in part to a Nutenschar and partially the other Nutenschar.

Eine vakuumgeformte Trägerplatte 1 aus einer Kunststoffolie ist durch zwei rechtwinklig zueinander verlaufende Nutenscharen mit den Nuten N1, N2 strukturiert. Die Nuten N1, N2 sind zu einer Seite der Platte 1 hin offen, so daß sich diese bei der in Figur 1a gezeigten Draufsicht als erhabene Stegbereiche S1 bzw. S2 darstellen. Die Stegbereiche S1 verlaufen in Längsrichtung der Platte 1; die Stegbereiche S2 verlaufen in Querrichtung. Die Nuten N1 und N2 schneiden sich rechtwinklig, wobei vorgesehen ist, daß die Nutenschar bildenden Nuten N1 und die die Nutenschar bildenden Nuten N2 jeweils einen gleichen Abstand zueinander aufweisen. Die Stegbereiche S1, S2 umschließen jeweils eine Mörtelkammer M1, in die Mörtel zum Anbringen eines Flächenbelages, beispielsweise eines Fliesenbelages eingebracht wird. Die Mörtelkammern M1 weisen einen voll umfänglich angeordneten Hinterschnitt H1 auf, so daß in eine Mörtelkammer M1 eingebrachter Mörtel nach seinem Aushärten formschlüssig darin gehalten ist und somit mit der Platte 1 verbunden ist. Die Darstellung des Hinterschnittes H1 einer Mörtelkammer M1 wird ebenfalls aus der Schnittdarstellung der Figur 1b deutlich. Unterseitig trägt die Platte 1 ein Vlies 2, welches zur Verklammerung der Platte 1 in einer auf einem Untergrund aufgebrachten Kontaktschicht dient. Ferner dient das Vlies 2 oder ein feinmaschiges Textilgewebe zur Verhinderung eines Verfüllens der rückseitig offenen Nuten N1 und N2 der Nutenscharen. Dabei kann das Vlies 2 durch eine Klebeverbindung an der Rückseite der Platte 1 befestigt oder in noch plastischem Zustand der Platte 1 rückseitig in diese eingedrückt sein.A vacuum-formed carrier plate 1 made of a plastic film is structured by two grooves extending at right angles to each other with the grooves N 1 , N 2 . The grooves N 1 , N 2 are open to one side of the plate 1, so that they are in the in FIG. 1a shown top view as raised land areas S 1 and S 2 represent. The web portions S 1 extend in the longitudinal direction of the plate 1; the web areas S 2 extend in the transverse direction. The grooves N 1 and N 2 intersect at right angles, wherein it is provided that the Nutenschar forming grooves N 1 and the Nutenschar forming grooves N 2 each have an equal distance from each other. The web portions S 1 , S 2 each enclose a mortar chamber M 1 , is introduced into the mortar for attaching a surface covering, such as a tile covering. The mortar chambers M 1 have a fully circumferentially arranged undercut H 1 , so that in a mortar chamber M 1 introduced mortar is held in a form-fitting manner after its curing and thus connected to the plate 1. The representation of the undercut H 1 of a mortar chamber M 1 is also from the sectional view of FIG. 1b clear. On the underside, the plate 1 carries a fleece 2, which serves to clamp the plate 1 in a contact layer applied to a substrate. Further, the nonwoven fabric 2 or a fine-meshed textile fabric serves to prevent filling of the grooves N 1 and N 2 of the groove flutes which are open at the rear. In this case, the nonwoven 2 can be attached by an adhesive bond to the back of the plate 1 or pressed in the still plastic state of the plate 1 back in this.

Der Hinterschnitt H1 der Platte wird dadurch ausgebildet, daß die Nuten N1, N2 oberseitig eine T-förmige Verbreiterung aufweisen. Eine solche hinterschnittene Ausbildung läßt sich beispielsweise durch einen Vakuumformprozeß erstellen. Anstelle der in den Figuren 1a und 1 b gezeigten Ausbildung des Hinterschnitts H1 kann dieser ebenfalls etwa schwalbenschwanzförmig ausgebildet sein.The undercut H 1 of the plate is formed by the fact that the grooves N 1 , N 2 have a T-shaped widening on the upper side. Such undercut training can be created for example by a vacuum forming process. Instead of in the FIGS. 1a and 1b shown embodiment of the undercut H 1 , this may also be formed approximately dovetailed.

Eine weitere gleichartige Trägerplatte 3 ist in den Figuren 2a und 2b dargestellt. Diese Platte 3 ist entsprechend der Platte 1 aufgebaut, weist jedoch im Unterschied zu der Kunststoffolie 1 Mörtelkammern M2 auf, die nur bereichsweise hinterschnitten sind. Die Hinterschnitte H2 dieser Platte 3 sind jeweils einer Nut N3, N4 bzw. einem Abschnitt des Steges S3 bzw. S4 zugeordnet. Die hinterschnittenen Bereiche der Stege S3 bzw. S4 sind durch zur Mörtelkammer M2 weisende Auskragungen, wie in Figur 2b verdeutlicht gebildet.Another similar support plate 3 is in the FIGS. 2a and 2b shown. This plate 3 is constructed according to the plate 1, but has, in contrast to the plastic film 1 mortar chambers M 2 , which are only partially undercut. The undercuts H 2 of this plate 3 are each assigned to a groove N 3 , N 4 or a section of the web S 3 or S 4 . The undercut areas of the webs S 3 and S 4 are through to the mortar chamber M 2 facing projections, as in FIG. 2b illustrated educated.

Noch eine weitere Trägerplatte 4 ist den Figuren 3a und 3b gezeigt, die ebenfalls aufgebaut ist wie die Platte nach den Figuren 1a und 1b mit dem Unterschied, daß die durch die Nuten N5, N6 gebildeten Stege S6, S6 in die Mörtelkammern M3 hineinragende Hinterschneidungen H3 definieren, die sich im Bereich der Kreuzungspunkte der Nuten N5, N6 bzw. der Stege S5, S8 befinden. Die Ausbildung des Hinterschnittes H3 wird insbesondere aus der Figur 3b ersichtlich.Yet another support plate 4 is the FIGS. 3a and 3b shown, which is also built like the plate after the FIGS. 1a and 1b with the difference that the webs formed by the grooves N 5 , N 6 S 6 , S 6 in the mortar chambers M 3 projecting undercuts H 3 define that in the region of the crossing points of the grooves N 5 , N 6 and the webs S. 5 , S 8 are located. The formation of the undercut H 3 is in particular from the FIG. 3b seen.

Figur 4 zeigt die Platte 1 in einer Einbausituation, bei der die Platte 1 mittels eines Klebers oder Mörtels 5 auf einem Untergrund 6 befestigt ist. Der in das Vlies 2 eindringende Mörtel 5 findet in dem Vlies 2 eine ausreichende Verklammerung zur Anbindung der Platte 1 an den Untergrund 6. Nach Befestigen der Platte 1 auf den Untergrund 6 wird die Platte 1 mit einem Mörtel 7 überdeckt, der in die Mörtelkammern M eindringt und auch hinter die Hinterschneidungen H1 eingebracht wird. Auf den Mörtel werden anschließend Fliesen 8 aufgelegt. Dabei ist vorgesehen, daß die Oberseiten der Stegbereiche S1, S2 nur in einer geringen Schichtdicke mit Kleber 7 bedeckt sind. Bei einem Einsatz des Fliesenbelages als Fußboden stützen sich die Fliesen 8 kräftemäßig stelzenartig über den in den Kammern M ausgehärteten Mörtel 7 untergrundseitig ab. Diese Mörtelstelzen sind durch die Nuten N1, N2 voneinander getrennt. Auftretende Scherkräfte zwischen dem Untergrund und dem Belag 8 können nunmehr wirkungsvoll durch die Trägerfolie 1 infolge der Anordnung der Nuten N1, N2 kompensiert, so daß eine durchgreifende Rißbildung vermieden ist. FIG. 4 shows the plate 1 in a mounting situation in which the plate 1 is fixed by means of an adhesive or mortar 5 on a substrate 6. The penetrating into the web 2 mortar 5 finds in the web 2 a sufficient Clamping to connect the plate 1 to the substrate 6. After attaching the plate 1 to the substrate 6, the plate 1 is covered with a mortar 7, which penetrates into the mortar chambers M and is also introduced behind the undercuts H 1 . Tiles 8 are then placed on the mortar. It is provided that the tops of the web portions S 1 , S 2 are covered with adhesive 7 only in a small layer thickness. When using the tile covering as a floor, the tiles 8 are supported by the force of stilts on the mortar 7 hardened in the chambers M on the underside. These mortar stilts are separated by the grooves N 1 , N 2 . Occurring shear forces between the substrate and the pad 8 can now effectively by the carrier film 1 due to the arrangement of the grooves N 1 , N 2 compensated, so that a thorough cracking is avoided.

Die niveaugleichen Stegoberseiten der Stegscharen bieten die Möglichkeit von abgedichteten Stoßverbindungen in unterschiedlichen Richtungen der durch die Stegoberseiten bestimmten Ebene mittels entsprechend breiten aufgeklebten Dichtbändem.The level web top sides of the webs provide the possibility of sealed butt joints in different directions of the plane defined by the web tops by means of correspondingly wide adhered Dichtbändem.
