Diese Trägerplatte besteht aus einer Platte aus Kunststoff mit einer Vielzahl von Vorsprüngen bzw. Vertiefungen, die einseitig hervorspringend aus einer Ebene der Trägerplatte ausgebildet sind. Auf einer ersten Plattenseite ist eine haftverstärkende Schicht vorgesehen, die den Konturen der ersten Plattenseite folgt. Auf der gegenüberliegenden Plattenseite ist eine weitere Schicht vorgesehen, die an den Vorsprüngen anliegt.From the DE 20 2011 110 801 U1 a carrier plate for a floor, wall or ceiling structure is known for achieving a decoupling between a substrate and a surface covering to be applied to a carrier plate. This support plate consists of a plate made of plastic with a large number of projections or depressions, which are designed to protrude on one side from a plane of the support plate. An adhesion-promoting layer is provided on a first side of the plate which follows the contours of the first side of the plate. A further layer is provided on the opposite side of the plate, which rests against the projections.

Aus der DE 10 2006 004 626 A1 ist ein Bauelement mit einem plattenförmigen Körper bekannt, das zumindest einen zweischichtigen Aufbau aufweist. Dieses Bauelement umfasst eine Trägerschicht aus einer folienartigen Platte, bei welcher Vorsprünge wechselseitig aus einer Mittelebene hervorstehen. Auf zumindest einer Seite der Trägerschicht bilden die Stirnflächen der Vorsprünge Kontaktflächen zur Aufnahme der zumindest einen Deckschicht, die als Kunststofffolie ausgebildet ist und eine Vielzahl von Durchbrechungen außerhalb der Kontaktflächen mit der Trägerschicht aufweist.From the DE 10 2006 004 626 A1 a component with a plate-shaped body is known which has at least a two-layer structure. This component comprises a carrier layer made of a foil-like plate, in which projections protrude alternately from a central plane. On at least one side of the carrier layer, the end faces of the projections form contact areas for receiving the at least one cover layer, which is designed as a plastic film and has a large number of openings outside the contact areas with the carrier layer.

Aus der EP 2 231 941 B1 ist eine Trägerplatte zur Einbindung in eine Bodenkonstruktion bekannt. Diese Trägerplatte besteht aus einer folienartigen Platte aus Kunststoff mit einer Vielzahl von Vorsprüngen und Vertiefungen. Auf einer ersten Plattenseite der folienartigen Platte ist eine haftverstärkende Schicht aufgebracht, die den Konturen der ersten Plattenseite folgt. Auf einer gegenüberliegenden Plattenseite kann eine weitere Schicht vorgesehen sein, welche an den Vorsprüngen anliegt und die Vertiefungen überspannt.From the EP 2 231 941 B1 a carrier plate for integration into a floor construction is known. This carrier plate consists of a foil-like plate made of plastic with a large number of projections and depressions. An adhesion-promoting layer, which follows the contours of the first side of the panel, is applied to a first panel side of the foil-like panel. A further layer can be provided on an opposite side of the plate, which rests against the projections and spans the depressions.

Die Vorsprünge in der folienartigen Platte sind einseitig eingeformt, das heißt, dass von einer ebenen folienartigen Platte einseitig Vorsprünge eingebracht werden, wobei zwischen den Vorsprüngen die Vertiefungen entstehen.The projections in the sheet-like plate are formed on one side, that is, one-sided projections from a flat sheet-like plate are introduced, wherein the depressions arise between the projections.

Der Erfindung liegt die Aufgabe zugrunde, eine Trägerplatte zu schaffen, welche eine verbesserte Entkopplung zu einem Untergrund und eine Erhöhung der Nutzlast ermöglicht.The invention is based on the object of creating a carrier plate which enables improved decoupling from an underground and an increase in the payload.

Diese Aufgabe wird durch eine Trägerplatte gelöst, bei welcher die Vorsprünge wechselseitig aus einer Ebene der folienartigen Platte hervorstehend ausgebildet sind, so dass eine Vielzahl von Zeilen und Spalten gebildet ist, bei denen abwechselnd Vorsprünge und Vertiefungen aneinandergereiht sind und entlang einer Diagonalen zu den Reihen und Spalten nur Vertiefungen und in einer weiteren Diagonale nur Vorsprünge aneinandergereiht sind. Eine solche Ausgestaltung der Trägerplatte ermöglicht eine vergrößerte Auflagefläche oder Kontaktfläche zum Untergrund als auch zu einer darauf aufgebrachten Verkleidung, da durch die beidseitige Ausformung von Vorsprüngen wechselseitig aus der Mittelebene der folienartigen Platte eine erhöhte Anzahl von Noppen geschaffen werden kann. Die Vorsprünge erstrecken sich in die eine und andere Richtung senkrecht zur Ebene der folienartigen Platte, so dass die Erhöhungen und Vertiefungen aneinandergrenzen, wodurch eine verbesserte Entkopplungsleistung ermöglicht wird.This object is achieved by a carrier plate in which the projections are designed to protrude alternately from a plane of the foil-like plate, so that a large number of rows and columns are formed, in which projections and depressions are lined up alternately and along a diagonal to the rows and Columns only depressions and in a further diagonal only projections are lined up. Such a configuration of the carrier plate enables an enlarged bearing surface or contact surface to the substrate and to a covering applied thereto, since an increased number of nubs can be created alternately from the central plane of the foil-like plate by forming projections on both sides. The protrusions extend in one direction and the other perpendicular to the plane of the sheet-like plate so that the peaks and valleys abut, allowing for improved decoupling performance.

Eine bevorzugte Ausgestaltung der Trägerplatte sieht vor, dass die wechselseitig aus der Ebene der folienartigen Platte herausgeformten Vorsprünge kegelstumpfförmig ausgebildet sind. Dies weist den Vorteil auf, dass an den jeweiligen Stirnseiten der Vorsprünge Auflageflächen geschaffen werden, um eine Flächenbekleidung, wie beispielsweise ein Fußbodenbelag, aufzunehmen. Alternativ können auch pyramidenstumpfförmige Vorsprünge vorgesehen sein.A preferred embodiment of the carrier plate provides that the projections formed alternately out of the plane of the foil-like plate are designed in the shape of a truncated cone. This has the advantage that contact surfaces are created on the respective end faces of the projections in order to accommodate a surface covering, such as a floor covering. Alternatively, truncated pyramid-shaped projections can also be provided.

Bevorzugt ist vorgesehen, dass entlang einer Diagonalen, in welcher Vertiefungen aufgereiht sind, zwischen zwei Vertiefungen ein Steg vorgesehen ist. Vorteilhafterweise ist analog entlang der weiteren Diagonalen, entlang der sich die Vorsprünge erstrecken, zwischen zwei Vorsprüngen ebenfalls ein Steg vorgesehen ist. Diese Stege liegen bevorzugt in der Mittelebene. Im jeweiligen Kreuzungspunkt der Diagonalen bilden die jeweiligen Stege vorteilhafterweise einen gemeinsamen Verbindungsabschnitt, deren äußere Randbereiche durch die daran angrenzenden Vertiefungen oder Vorsprünge gebildet und begrenzt sind.Provision is preferably made for a web to be provided between two depressions along a diagonal in which depressions are lined up. Advantageously, along the further diagonal along which the projections extend, a web is also advantageously provided between two projections. These webs are preferably in the middle plane. At the respective crossing point Diagonals, the respective webs advantageously form a common connecting section, the outer edge regions of which are formed and delimited by the depressions or projections adjoining them.

Des Weiteren ist bevorzugt vorgesehen, dass zwischen einander zugeordneten Vorsprüngen und Vertiefungen in der Mittelebene ein sternförmiger Verbindungsabschnitt ausgebildet ist. Dadurch kann eine gleichmäßige Kräfteableitung in alle an den sternförmigen Verbindungsabschnitt angrenzenden Vorsprünge und Vertiefungen erfolgen.Furthermore, it is preferably provided that a star-shaped connecting section is formed between mutually associated projections and depressions in the center plane. As a result, a uniform dissipation of forces can take place in all projections and depressions adjacent to the star-shaped connecting section.

Des Weiteren ist bevorzugt vorgesehen, dass die Vorsprünge sich wechselseitig zur Mittelebene mit gleicher Höhe erstrecken. Insbesondere ist eine Höhe ausgehend von der Mittelebene von kleiner als 5 mm, insbesondere kleiner als 3 mm, vorgesehen.Furthermore, it is preferably provided that the projections extend alternately to the central plane with the same height. In particular, a height starting from the center plane of less than 5 mm, in particular less than 3 mm, is provided.

Des Weiteren ist zur Erhöhung der Lastaufnahme bzw. Nutzlast vorgesehen, dass die Anzahl der Noppen größer als 9.000 Stück/qm ist. Bevorzugt sind mehr als 20.000 Vorsprünge je Quadratmeter vorgesehen, insbesondere 22.500 oder 25.600 Vorsprünge je Quadratmeter. Beispielsweise kann die Anzahl der Vorsprünge in einem Bereich zwischen 22.500 bis zu 90.000 Noppen/Vorsprünge je Quadratmeter liegen. Diese Anzahl umfasst alle gegenüber der Mittelebene hervorstehenden Vorsprünge sowohl auf der ersten Plattenseite als auch auf der zweiten Plattenseite.Furthermore, to increase the load capacity or payload, the number of knobs is greater than 9,000 pieces/sqm. More than 20,000 projections per square meter are preferably provided, in particular 22,500 or 25,600 projections per square meter. For example, the number of protrusions can range from 22,500 up to 90,000 nubs/protrusions per square meter. This number includes all of the projections protruding from the center plane, both on the first side of the plate and on the second side of the plate.

Des Weiteren ist bevorzugt vorgesehen, dass die Stirnfläche der Vorsprünge einen Durchmesser von 3 bis 8 mm aufweist. Dadurch wird eine maximale Auflagefläche und eine hinreichende Kraftableitung über die schrägen Mantelflächen der Vorsprünge ermöglicht.Furthermore, it is preferably provided that the end face of the projections has a diameter of 3 to 8 mm. This enables a maximum bearing surface and a sufficient dissipation of force via the sloping lateral surfaces of the projections.

Insbesondere ist die folienartige Platte der Trägerplatte aus LDPE (Low-Density-Polyethylen) ausgebildet. Durch diesen weichen und elastischen Werkstoff kann eine verbesserte Entkopplung erzielt werden. Die Trägerplatte kann auch aus HDPE (High-Density-Polyethylen), PE (Polyethylen) oder PP (Polypropylen) ausgebildet sein. Bevorzugt wird dabei eine Stärke der folienartigen Platte von 0,1 bis 2 mm eingesetzt.In particular, the foil-like plate of the carrier plate is made of LDPE (low-density polyethylene). Improved decoupling can be achieved with this soft and elastic material. The carrier plate can also be made of HDPE (high-density polyethylene), PE (polyethylene) or PP (polypropylene). A thickness of the foil-like plate of 0.1 to 2 mm is preferably used.

Als haftverstärkende Schicht, welche den Konturen der ersten Plattenseite folgt, ist bevorzugt ein Vlies oder ein Filz vorgesehen. Dadurch kann beim Aufbringen eines Klebemittels zur Fixierung einer Flächenbegleitung eine Verkrallung des Klebemittels mit dem Vlies oder Filz erfolgen.A fleece or a felt is preferably provided as an adhesion-enhancing layer which follows the contours of the first side of the plate. As a result, when an adhesive is applied to fix a surface accompaniment, the adhesive can grip the fleece or felt.

Bevorzugt weist die Trägerplatte mit der daran vorgesehenen haftverstärkenden Schicht und der weiteren Schicht ein Flächengewicht von 400 g/m2 bis 700 g/m2, vorzugsweise von 500 bis 600 g/m2, auf.The carrier plate with the adhesion-promoting layer provided thereon and the additional layer preferably has a basis weight of 400 g/m 2 to 700 g/m 2 , preferably 500 to 600 g/m 2 .

Des Weiteren ist bevorzugt vorgesehen, dass die weitere Schicht auf der zweiten Plattenseite ein Vlies, ein Filz, ein textiles Material, ein maschenartiges Gewebe oder netzartiges Gewebe oder eine perforierte Schicht ist. Dadurch kann eine Belüftung zwischen dem Untergrund und der folienartigen Platte erfolgen.Furthermore, it is preferably provided that the further layer on the second side of the plate is a fleece, a felt, a textile material, a mesh-like fabric or a net-like fabric or a perforated layer. This allows ventilation between the substrate and the sheet-like panel.

Diese Trägerplatte gemäß einer der vorbeschriebenen Ausführungsformen wird bevorzugt zur Entkopplung einer Flächenbekleidung auf einem darauf aufzubauenden Untergrund verwendet. Dadurch kann eine Spannungsentkopplung zwischen der Flächenbekleidung und dem Untergrund ermöglicht sein. Darüber hinaus kann auch eine Schallentkopplung, insbesondere Trittschallentkopplung, gegeben sein.This carrier plate according to one of the above-described embodiments is preferably used for decoupling a surface covering on a subsurface to be built up thereon. This can enable stress decoupling between the surface covering and the subsurface. In addition, there can also be sound decoupling, in particular impact sound decoupling.

Die Erfindung sowie weitere vorteilhafte Ausführungsformen und Weiterbildungen derselben werden im Folgenden anhand der in den Zeichnungen dargestellten Beispiele näher beschrieben und erläutert. Es zeigen:

  • Figur 1 eine schematische Schnittdarstellung der Trägerplatte in einer Einbauposition zum Entkoppeln einer Flächenbekleidung zum Untergrund, und
  • Figur 2 eine schematische Ansicht auf die Trägerplatte gemäß Figur 1.
The invention and other advantageous embodiments and developments thereof are described and explained in more detail below with reference to the examples shown in the drawings. Show it:
  • figure 1 a schematic sectional view of the carrier plate in an installed position for decoupling a surface covering from the subsurface, and
  • figure 2 according to a schematic view of the carrier plate figure 1 .

Figur 1 zeigt eine schematische Schnittansicht einer Trägerplatte 11, welche in einer Draufsicht in Figur 2 dargestellt ist. Diese Trägerplatte 11 besteht aus einer folienartigen Platte 12 aus Kunststoff, welche eine Vielzahl von Vorsprüngen 14 aufweist. Diese Vorsprünge 14 sind beidseitig zu einer Mittelebene 16 ausgebildet, wobei die Mittelebene 16 der Ebene der folienartigen Platte 12 im Rohzustand entspricht. Die Vorsprünge 14 werden somit wechselseitig zu einer ersten Plattenseite 17 und einer zweiten Plattenseite 18 der folienartigen Platte 12 ausgeformt. Dadurch entstehen wechselseitig auch Vertiefungen 19. Die Vorsprünge 14 und Vertiefungen 19 sind abwechselnd zueinander in Reihen und Spalten angeordnet. Dies geht in der Draufsicht aus Figur 2 hervor. Entlang einer ersten Diagonalen 21 sind Vertiefungen 19 vorgesehen. Zwischen zwei Vertiefungen 19 erstreckt sich ein Steg 25, der vorzugsweise in der Mittelebene 16 liegt. In einer weiteren Diagonalen 22 um 90° versetzt zur Diagonalen 21 sind Vorsprünge 14 aneinandergereiht. Zwischen zwei Vorsprüngen 14 erstreckt sich ein Steg 25, der vorzugsweise in der Mittelebene 16 liegt. figure 1 shows a schematic sectional view of a carrier plate 11, which is shown in a plan view in figure 2 is shown. This carrier plate 11 consists of a foil-like plate 12 made of plastic, which has a large number of projections 14 . These projections 14 are formed on both sides to form a central plane 16, the central plane 16 corresponding to the plane of the sheet-like panel 12 in the raw state. The projections 14 are thus shaped alternately to form a first plate side 17 and a second plate side 18 of the sheet-like plate 12 . This also results in alternating depressions 19. The projections 14 and depressions 19 are arranged alternately with one another in rows and columns. This goes out in the top view figure 2 out. Indentations 19 are provided along a first diagonal 21 . Between two indentations 19 there extends a web 25 which preferably lies in the center plane 16 . In a further diagonal 22 offset by 90° to the diagonal 21, projections 14 are lined up. Between two projections 14 there extends a web 25 which preferably lies in the center plane 16 .

Durch das beidseitige Ausformen der Vorsprünge 14 aus der Mittelebene 16 entstehen in der Mittelebene 16 in der Schnittansicht gesehen horizontal ausgebildete Stützabschnitte 23. Diese Stützabschnitte 23 umgeben ringförmig die Vorsprünge 14 beim Wechsel von der einen Plattenseite 17 zur anderen Plattenseite 18. In der Draufsicht gesehen ergibt sich aufgrund der beidseitig zur Mittelebene 16 eingebrachten Vorsprünge 14 bzw. der wechselseitig angeordneten Vorsprünge 14 und Vertiefungen 19 durch die Stege 25 ein sternförmiger Abschnitt 24. Dieser geht bevorzugt auch bündig in die Stege 23 über.The two-sided shaping of the projections 14 from the center plane 16 results in the center plane 16 seen in the sectional view, horizontally formed support sections 23. These support sections 23 surround the projections 14 in a ring shape when changing from one side 17 of the plate to the other side 18 of the plate due to the projections 14 introduced on both sides of the central plane 16 or the alternately arranged projections 14 and depressions 19 through the webs 25, a star-shaped section 24. This preferably also merges flush into the webs 23.

Auf einer ersten Plattenseite 17 ist eine haftverstärkende Schicht 26 vorgesehen. Diese Schicht 26 folgt der Kontur der ersten Plattenseite 17 und überdeckt diese bevorzugt vollständig. Diese Schicht 26 kann aufgeklebt oder auflaminiert oder aufgeschweißt sein. Bevorzugt besteht die haftverstärkende Schicht 26 aus einem Vlies, insbesondere aus Polypropylen oder Polyethylen. Alternativ kann als haftverstärkende Schicht 26 auch ein vorzugsweise feinmaschiges Gewebe, ein Gewirke, ein textiles Material oder ein perforiertes Vlies oder ein perforierter Filz vorgesehen sein.An adhesion-promoting layer 26 is provided on a first side 17 of the plate. This layer 26 follows the contour of the first plate side 17 and preferably covers it completely. This layer 26 can be glued on or laminated on or welded on. The adhesion-reinforcing layer 26 preferably consists of a fleece, in particular of polypropylene or polyethylene. Alternatively, a preferably fine-meshed woven fabric, a knitted fabric, a textile material or a perforated fleece or a perforated felt can also be provided as the adhesion-reinforcing layer 26 .

Auf der zweiten Plattenseite 18 ist an Stirnseiten 28 der Vorsprünge 14 eine weitere Schicht 29 vorgesehen. Diese Schicht 29 überspannt bevorzugt die zwischen den Vorsprüngen 14 ausgebildeten Vertiefungen 19. Diese weitere Schicht 29 kann ein netzartiges Gewebe, ein feinmaschiges Gewebe, ein perforiertes Vlies oder dergleichen sein. Diese weitere Schicht 29 ist mit den Stirnseiten 28 der Vorsprünge 14 verklebt oder verschweißt.A further layer 29 is provided on the end faces 28 of the projections 14 on the second plate side 18 . This layer 29 spans preferably the depressions 19 formed between the projections 14. This further layer 29 can be a net-like fabric, a fine-meshed fabric, a perforated fleece or the like. This further layer 29 is glued or welded to the end faces 28 of the projections 14 .

Die Trägerplatte 11 wird beispielsweise zur Entkopplung einer Flächenbekleidung 31 auf einem Untergrund 32 eingesetzt. Dies ist beispielhaft in Figur 1 dargestellt. Die Trägerplatte 11 wird mit der zweiten Plattenseite 18 auf den Untergrund 32 aufgelegt. Alternativ kann diese weitere Schicht 29 mit dem Untergrund 32 verklebt werden. Dabei wird nur eine geringe Menge an Klebemittel aufgebracht, so dass die Vertiefungen 19 frei von Klebemittel oder Mörtel bleiben.The carrier plate 11 is used, for example, to decouple a surface covering 31 on a substrate 32 . This is an example in figure 1 shown. The carrier plate 11 is placed on the base 32 with the second plate side 18 . Alternatively, this additional layer 29 can be glued to the substrate 32 . In this case, only a small amount of adhesive is applied, so that the depressions 19 remain free of adhesive or mortar.

Auf der gegenüberliegenden ersten Plattenseite 17 wird Klebemittel oder Mörtel 34 aufgebracht, um die Flächenbekleidung 31 zur Trägerplatte 11 zu fixieren. Die Flächenbekleidung 31 kann aus einzelnen Fliesen oder Platten, aber auch als Laminat aus Harz oder dergleichen ausgebildet sein.Adhesive or mortar 34 is applied to the opposite first panel side 17 in order to fix the surface covering 31 to the carrier panel 11 . The surface covering 31 may be formed of individual tiles or plates, but also may be formed of a laminate of resin or the like.

Die Trägerplatte 11 weist durch die Vielzahl der aus der Mittelebene 16 herausgeformten Vorsprünge 14 eine erhöhte Traglast bzw. Nutzlast auf. Es sind 9.000 Stück Vorsprünge pro Quadratmeter oder mehr als 20.000 Stück Vorsprünge pro Quadratmeter, vorgesehen. Die Steigung der kegelförmigen Wandabschnitte der Vorsprünge 14 verläuft zu einer Vertikalen der Mittelebene 16 bevorzugt in einem Bereich zwischen 10° und 20°. Die beidseitig gegenüber der Mittelebene 16 sich erstreckenden Vorsprünge 14 weisen eine Höhe von weniger als 5 mm auf. Bevorzugt ist die Höhe der Vorsprünge beidseitig zur Mittelebene 16 gleich.Due to the large number of projections 14 formed out of the central plane 16, the carrier plate 11 has an increased load capacity or payload. There are provided 9,000 pieces of protrusions per square meter or more than 20,000 pieces of protrusions per square meter. The slope of the conical wall sections of the projections 14 preferably runs in a range between 10° and 20° with respect to a vertical line of the center plane 16 . The projections 14 extending on both sides with respect to the central plane 16 have a height of less than 5 mm. The height of the projections is preferably the same on both sides of the center plane 16 .
