Description

Die Erfindung betrifft Drainagematerial für die Drainierung von auf witterungsbedingt oder aus anderen Gründen dem Zutritt von Wasser oder anderen flüssigen Medien ausgesetzten Treppenstufen aufgebrachten Belägen, wie Platten aus keramischem Material oder Betonwerkstoffen, Kunst- oder Natursteinplatten etc.The invention relates to drainage material for the drainage of on weather-related or other reasons, the access of water or other liquid media exposed steps applied coatings, such as plates of ceramic material or concrete materials, art or natural stone slabs, etc.

Witterungseinflüssen ausgesetzte Treppen im Außenbereich werden heute - ebenso wie Balkone oder Terrassen - in der Regel mit auf den freiliegenden Oberseiten, d. h. den Auftrittsflächen und den hier anschließenden senkrechten Stoßtrittflächen auf der Roh-Betontreppe aufgebrachten Platten, keramischen Fliesen oder Natur- bzw. Kunststeinplatten belegt. Über die Fugen der Plattenbeläge eintretende Nässe wird dabei durch den Estrich in eine darunter liegende Schicht aus einem Drainagematerial entwässert, welches die durchtretende Flüssigkeit über die Entwässerungskanäle des Drainagematerials ableitet. Für die Entwässerung der Oberflächen von Balkonen bzw. Terrassen werden bahnen- oder plattenförmige Drainagematerialen verwendet, bei denen die Entwässerungskanäle in einem entweder aus geschlossenzelligem Schaumkunststoff oder eigensteifen profilierten Kunststofffolien hergestellten Trägermaterial ausgebildet sind, auf dem eine flüssigkeitsdurchlässige Abdeckbahn aufgebracht ist, über welche im Estrich enthaltende oder in den Estrich eingedrungene Nässe in die Entwässerungskanäle abgeführt werden kann. Solches Drainagematerial auf der Basis von Schaumkunststoff ist beispielsweise in der DE 34 14 249 A1 bzw. DE 440 3 875 C2 beschrieben. Drainagematerial mit einem Trägermaterial auf der Basis von profilierten Kunststofffolien sind andererseits aus der DE 490 4 901 C2 bekannt. Bei diesem bekannten Drainagematerialen werden als wasserdurchlässige Abdeckungen so genannte Vliese verwendet, welche nur Flüssigkeiten, d. h. in der Regel Wasser, nicht aber feste Zuschlagstoffe aus dem in fließfähigem Zustand aufgebrachten Estrich hindurch treten lassen. Bei der Belegung von Treppenstufen mit Plattenbelägen wurden bisher die bekannten bahn- oder plattenförmigen Drainagematerialien eingesetzt. Für jede Treppenstufe müssen diese bekannten Drainagematerialien entsprechend der Form und Größe der horizontalen Auftritt- bzw. vertikalen Stossfläche aus dem bahn- oder plattenförmigen bekannten Drainagematerial zugeschnitten werden, wobei dieser Zuschnitt auch noch so erfolgen muss, dass die beim Aufbringen der Zuschnitte auf die Treppenstufen die in den den Auftrittflächen zugeordneten Zuschnitten vorgesehenen Entwässerungskanäle mit den in den Stoßtrittflächen der Treppenstufe zugeordneten Zuschnitten vorgesehenen Entwässerungskanäle fluchten, um sicherzustellen, dass durch die Fugen der Beläge hindurchtretendes Wasser auch tatsächlich über die zueinander ausgerichteten Entwässerungskanäle der Stufen der gesamten Treppe abgeführt wird. Es ist klar, dass der korrekte Zuschnitt der Drainagematerialien für die Oberflächen der Treppenstufen und die gesonderte Aufbringung der einzelnen Zuschnitte ein arbeitsaufwendiger und hinsichtlich der korrekten Verlegung kritischer Vorgang ist.Today exposed to the weather influences stairs in the outdoor area are - as well as balconies or terraces - usually occupied on the exposed tops, ie the treads and the subsequent vertical bump surfaces on the raw concrete stairs applied plates, ceramic tiles or natural or artificial stone slabs. Wetness entering through the joints of the tile coverings is dewatered by the screed into an underlying layer of drainage material which drains the passing liquid via the drainage channels of the drainage material. For the drainage of the surfaces of balconies or terraces, sheet or plate-shaped drainage materials are used, in which the drainage channels are formed in a carrier material made of either closed-cell foam plastic or intrinsically stiff profiled plastic films, on which a liquid-permeable cover sheet is applied, over which in the screed or in the screed moisture penetrated into the drainage channels can be removed. Such drainage material based on foam plastic is for example in the DE 34 14 249 A1 respectively. DE 440 3 875 C2 described. Drainage material with a carrier material on the basis of profiled plastic films on the other hand from the DE 490 4 901 C2 known. In this known drainage materials are used as water-permeable covers so-called nonwovens, which can only liquids, ie usually water, but not solid additives from the applied in flowable condition screed pass. When occupying stair treads with plate coverings, the known sheet or plate-shaped drainage materials have hitherto been used. For each step, these known drainage materials must be tailored in accordance with the shape and size of the horizontal appearance or vertical abutting surface of the web or plate-shaped known drainage material, this blank must also be made so that when applying the blanks on the stairs provided in the blanks associated with the blanks Drainage channels with the provided in the bump surfaces of the step blanks associated drainage channels are aligned to ensure that passing through the joints of the coverings water is actually discharged through the aligned drainage channels of the steps of the entire staircase. It is clear that the correct cutting of the drainage materials for the surfaces of the steps and the separate application of the individual blanks is a laborious and critical to the correct installation process.

Der Erfindung liegt die Aufgabe zugrunde, ein Drainagematerial für die Drainierung von Plattenbelägen auf Treppenstufen zu schaffen, welches einen einfacheren und zeitsparenderen Verlegevorgang auf den Flächen der Treppenstufen ermöglicht und bei welchem Probleme bezüglich der korrekten Ausrichtung der Entwässerungskanäle von aufeinander folgenden Trägermaterial-Abschnitten relativ zueinander vermieden sind.The invention has for its object to provide a drainage material for the drainage of tile coverings on stairs, which allows a simpler and more time-saving installation process on the surfaces of the stairs and in which problems with respect to the correct orientation of the drainage channels of successive carrier material sections relative to each other avoided are.

Diese Aufgabe erfindungsgemäß gelöst durch ein Drainagematerial, welches ein System von zumindest zum Teil mit einander verbundenen Vertiefungen zur Abfuhr von belagseitig zutretender Flüssigkeit versehenes, unter den Belägen auf den Flächen der Stufen aufzubringendes Trägermaterial aufweist, das auf seiner belagszugewandten Oberseite zumindest abschnittsweise mit einer flüssigkeitsdurchlässigen Abdeckbahn versehen ist, wobei das Trägermaterial zwei in der bestimmungsgemäßen Verlegeposition auf einer Treppe entlang einer parallel zu zwischen einer horizontalen Auftrittsfläche und einer anschließenden senkrechten Stoßtrittfläche gebildeten Stufenkante der Treppenstufen verlaufenden geraden Linie im Wesentlichen rechtwinklig zueinander gekantete integral miteinander verbundene Trägermaterial-Abschnitte aufweist, welche in ihrer Flächengröße so bemessen sind, dass der in der bestimmungsgemäßen Verlegeposition der Auftrittfläche zugeordnete erste Abschnitt in seiner parallel zur Stufenkante gemessenen Breite im Wesentlichen der Länge der Stufenkante und der zweite rechtwinklig zum ersten Abschnittverlaufende Abschnitt in seiner Breite ebenfalls im wesentlichen der Länge der Stufenkante und in seiner Höhe im Wesentlichen der senkrechten Höhe der an die Auftrittfläche anschließenden Stoßtrittfläche der mit dem Plattenbelag zu versehenden Treppenstufe entspricht. Mit dem so ausgebildeten Drainagematerial können also in einem Arbeitsgang jeweils eine Auftritts- und eine anschließende Stoßtrittfläche von Treppenstufen einer Rohbeton-Treppe belegt werden, nachdem die den beiden Flächen jeweils zugeordneten Abschnitten - erforderlichenfalls - zuvor entsprechend der Form und Größe der zugeordneten Flächen beschnitten sind.This object is achieved according to the invention by a drainage material which has a system of at least partially interconnected recesses for removal of fluid on the side facing zutretender, applied under the coverings on the surfaces of the stages support material on its facing the top facing at least partially with a liquid-permeable cover web is provided, wherein the carrier has two in the intended laying position on a staircase along a parallel to formed between a horizontal tread surface and a subsequent vertical bump surface step edge of the stairs straight line substantially at right angles to each other folded integrally interconnected carrier material sections which in their Surface size are dimensioned so that the assigned in the intended laying position of the tread surface first section in his measured parallel to the step edge width substantially the length of the step edge and the second section extending at right angles to the first section also corresponds in its width substantially to the length of the step edge and in its height substantially to the vertical height of the impact surface adjoining the step surface of the step to be paved. With the thus formed drainage material so in each case an occurrence and a subsequent bumping surface of steps of a rough concrete stairs can be occupied after the two surfaces respectively assigned sections - if necessary - previously trimmed according to the shape and size of the associated surfaces.

Dabei ist die Ausgestaltung zweckmäßig so getroffen, dass der der horizontalen Auftrittsfläche einer Treppenstufe zugeordnete Trägermaterial-Abschnitt im Wesentlichen rechtwinklig am oberen Rand des der senkrechten Stoßtrittfläche der selben Treppenstufe zugeordneten Trägermaterial-Abschnitts angesetzt ist. Der Verlegevorgang des Trägermaterials erfolgt dann also jeweils aufeinander folgend auf der gleichen Stufe.In this case, the configuration is expediently made such that the carrier material section assigned to the horizontal tread surface of a step is attached substantially at right angles to the upper edge of the carrier material section associated with the vertical tread surface of the same step. The laying process of the carrier material is then carried out in succession at the same stage.

Alternativ ist dass der der horizontalen Auftrittsfläche einer Treppenstufe zugeordnete Trägermaterial-Abschnitt im Wesentlichen rechtwinklig am unteren Rand des der senkrechten Stoßtrittfläche der in Aufwärtsrichtung anschließenden nächsten Treppenstufe zugeordneten Trägermaterial-Abschnitts angesetzt ist. Dieses Trägermaterials wird dann so verlegt, dass es gleichzeitig auf der Auftrittsfläche einer Treppenstufe und der Stoßtrittfläche der in Aufwärtsrichtung anschließenden nächst höheren Treppenstufe aufgebracht wird.Alternatively, that of the horizontal tread surface of a step assigned carrier material section is attached substantially perpendicular to the lower edge of the vertical bump surface of the adjoining in the upward direction next step carrier material section. This carrier material is then laid so that it is applied simultaneously on the tread surface of a step and the bumping surface of the subsequent next higher step in the upward direction.

Die rechtwinklig zur Stufenkante gemessene horizontale Tiefe des der Auftrittsfläche zugeordneten ersten Trägermaterial-Abschnitts kann dabei im Wesentlichen der Tiefe der Auftrittsfläche der zugeordneten Treppenstufe entsprechend bemessen sein.The horizontal depth of the first carrier material section assigned to the tread surface, which is measured at right angles to the step edge, can be dimensioned essentially corresponding to the depth of the tread surface of the associated step.

Alternativ kann die rechtwinklig zur Stufenkante gemessene horizontale Tiefe des der Auftrittsfläche zugeordneten ersten Trägermaterial-Abschnitts eine geringere Tiefenerstreckung als die Auftrittsfläche haben.Alternatively, the horizontal depth of the first carrier material section, which is measured at right angles to the step edge, can have a smaller depth extension than the tread surface.

Das System der zumindest zum Teil mit einander verbundenen Vertiefungen zur Abfuhr von belagseitig zutretender Flüssigkeit weist in bevorzugter Ausgestaltung der Erfindung parallel zueinander und rechtwinklig zur Stufenkante verlaufende langgestreckte Entwässerungskanäle auf, wobei die in den der Auftrittsfläche und der anschließenden Stoßtrittfläche der Treppenstufe zugeordneten Trägermaterial-Abschnitte vorgesehenen Entwässerungskanäle dann zweckmäßig so zueinander ausgerichtet sind, dass sie fluchtend ineinander übergehen.In a preferred embodiment of the invention, the system of at least partially interconnected recesses for the removal of fluid to be coated has elongate drainage channels running parallel to each other and at right angles to the step edge, the support material sections assigned to the step surface and the adjoining impact surface of the step Drainage channels are then suitably aligned with each other so that they merge into one another.

In einem vorteilhaften Ausführungsbeispiel der Erfindung weist das Trägermaterial eine durch Einformen der parallelen lang gestreckten Kanäle perforierte Kunststoffträgerfolie auf, auf welche die flüssigkeitsdurchlässige Abdeckbahn belagsseitig aufgebracht ist.In an advantageous embodiment of the invention, the carrier material has a perforated by molding the parallel elongated channels plastic carrier film, on which the liquid-permeable cover sheet is applied on the coating side.

Wenn als Trägermaterial für die flüssigkeitsdurchlässige Abdeckbahn eine profilierte Kunststofffolie verwendet ist, dessen Trägermaterial-Abschnitte entlang der Kantlinie integral miteinander verbunden sind, kann seine Herstellung kann so erfolgen, dass ein zunächst gemeinsamer ebenflächiger Zuschnitt aus dem - an sich bekannten - Drainagematerial mit einem Trägermaterial aus profilierter Kunststofffolie ausgeschnitten oder ausgestanzt wird und dann die einzelnen Flächenabschnitte entlang der gemeinsamen Kantlinie, die im Wesentlichen rechtwinklig zueinander verlaufende Position gebogen werden. Dabei ist es dann zweckmäßig, wenn dieser Biegeschritt entlang der Kantlinie bei erhöhter Temperatur des Kunststofffolienmaterials - d. h. entweder unmittelbar im Anschluss an die Warmprofilierung der ursprünglich ebenflächigen Kunststofffolie oder durch nachträglich auf die abgekühlte Folie zur Einwirkung gebrachte Wärmeenergie - erfolgt, so dass sichergestellt ist, dass die rechtwinklige Ausrichtung der Flächenabschnitte zueinander nach dem Abkühlen des Kunststofffolien-Trägermaterials fixiert ist. Auch die vollständige Profilierung der Kunststofffolie bzw. von Zuschnitten der Kunststofffolie in Tiefziehwerkzeugen ist möglich.If a profiled plastic film is used as the carrier material for the liquid-permeable cover web, the carrier material sections of which are integrally connected to one another along the edge line, its production can be carried out in such a way that an initially common planar blank of the - known per se - drainage material with a carrier material profiled plastic film is cut or punched out and then the individual surface portions along the common edge line, which are bent substantially perpendicular to each other position. In this case, it is expedient if this bending step takes place along the edge line at elevated temperature of the plastic film material, ie either immediately after the hot profiling of the originally planar plastic film or by subsequently applied heat energy to the cooled film, so as to ensure that the rectangular orientation of the surface portions to each other after cooling of the plastic film substrate is fixed. The complete profiling of the plastic film or blanks of the plastic film in thermoforming tools is possible.

Alternativ kann das Trägermaterial von mit den eingeformten parallelen Kanälen versehenen Abschnitten aus Schaumkunststoff gebildet sein, auf welchem die flüssigkeitsdurchlässige Abdeckbahn aufgebracht ist.Alternatively, the carrier material may be formed by sections of foam plastic provided with the molded-in parallel channels, on which the liquid-permeable covering web is applied.

Dabei wird die Ausgestaltung dann zweckmäßig so getroffen, dass die als gesonderte Teile hergestellten Trägermaterial-Abschnitte entlang der an der Kantlinie zusammentreffenden Ränder durch ein haftend auf den Randbereichen aufgebrachtes Gewebe- oder Folienband miteinander verbunden sind.The design is then expediently made so that the carrier material sections produced as separate parts are connected to one another along the edges meeting on the edge line by a fabric or film strip applied adhesively on the edge regions.

Die flüssigkeitsdurchlässige Abdeckbahn wird bevorzugt von einem Vliesmaterial gebildet, welches also flüssige Bestandteile des anschließend für die Belegung mit den Plattenbelägen aufgebrachten abbindenden Estrichs ebenso wie später über die Fugen der Beläge in den Estrich eindringendes Wasser in die Entwässerungskanäle durchtreten lässt.The liquid-permeable covering web is preferably formed by a non-woven material, which thus allows liquid components of the subsequently applied for the occupation of the plate coverings screed screed as well as later penetrate through the joints of the coverings in the screed penetrating water into the drainage channels.

Alternativ kann die flüssigkeitsdurchlässige Abdeckbahn von einem für den Durchtritt von noch nicht abgebundenem oder ausgehärtetem Estrich-Mörtel, und zwar in diesem Fall einem so genannten Einkorn- oder Monokornmörtel, durchlässigen, eine Armierung des ausgehärteten oder abgebundenen Mörtels bildenden Gittergewebe aus hochfesten Fasern oder Fäden gebildet werden.Alternatively, the liquid-permeable cover web of a for the passage of not yet set or cured screed mortar, in this case a so-called Einkorn- or Monokornmörtel, permeable, a reinforcement of the cured or hardened mortar forming mesh fabric made of high-strength fibers or filaments become.

Als Gittergewebe wird in einem Faii das auch bei den bekannten für die Fiächendrainierung in den Drainagematerialien eingesetzte hochfeste Gittergewebe aus Glas-Fasern oder Fäden verwendet.As a mesh fabric is used in a Faii that also used in the known for the Fiächendrainierung in the drainage materials high-strength mesh fabric of glass fibers or filaments.

Das Trägermaterial kann alternativ auch von für jeden Trägermaterial-Abschnitt gesondert hergestellten, in parallelem Abstand auf der Unterseite der Abdeckbahn haftend aufgebrachten langgestreckten leistenartigen Schaumkunststoff-Trägerelementen gebildet werden, welche durch die Abdeckbahn zu einer Einheit verbunden sind, wobei die einander zuwandten Enden der in beiden Flächenabschnitten ausgerichtet zueinander auf der Abdeckbahn angeordneten Trägerelemente so geformt sind, dass sie die rechtwinklige Ausrichtung der beiden Trägermaterialabschnitte relativ zueinander zulassen. D. h. die einander zugewandten Enden der Trägerelemente sind sozusagen auf Gehrung geschnitten.Alternatively, the carrier material can also be formed by elongate strip-like foam plastic carrier elements which are produced separately for each carrier material section and are adhesively applied at a parallel spacing on the underside of the cover web, which are connected by the cover web to form a unit, the ends facing each other being in both Surface portions arranged aligned with each other on the cover sheet Carrier elements are shaped so that they allow the orthogonal alignment of the two carrier material sections relative to each other. Ie. the mutually facing ends of the support elements are cut miter, so to speak.

Bei Verlegung der Plattenbeläge auf einem aus dem Drainagematerial aufgebrachten Estrich überdeckt die flüssigkeitsdurchlässige Abdeckbahn mit Vorteil beide Trägermaterial-Abschnitte im Wesentlichen vollflächig.When laying the tile coverings on a screed applied from the drainage material, the liquid-permeable cover web advantageously covers both backing material sections over the entire area.

Wenn andererseits für die Aufbringung des Plattenbelags auf der Auftrittfläche Einkorn-Mörtel verwendet wird, während die auf der Stossfläche aufzubringenden Plattenbeläge über einen Klebemörtel mit dem Trägermaterial verbunden werden sollen, kann die Ausgestaltung auch so getroffen sein, dass die flüssigkeitsdurchlässige Abdeckbahn den zweiten, der Stoßtrittfläche einer Treppenstufe zugeordnete Trägermaterial-Abschnitt im Wesentlichen vollflächig und zusätzlich einen an die Kantlinie der Abschnitte anschließenden streifenförmigen Randbereich des ersten Trägermaterial-Abschnitts überdeckt. Durch diesen einen streifenförmigen Randbereich des ersten Trägermaterial-Abschnitts überdeckenden streifenförmigen Abschnitt der Abdeckbahn wird erreicht, dass beim Aufbringen des Einkorn-Mörtels auf die horizontale Oberfläche des Drainagematerials kein Mörtel in die senkrechten Entwässerungskanäle in den der Stossfläche zugeordneten Trägermaterial-Abschnitt eindringen kann.If, on the other hand, single grain grout is used for the application of the tile covering on the tread surface, while the tile coverings to be applied to the tipping face are to be bonded to the substrate via an adhesive mortar, the design may also be such that the liquid permeable cover web is the second, bump tread a substrate step associated carrier material portion substantially over the entire surface and additionally covers a subsequent to the crease line of the sections strip-shaped edge region of the first carrier material portion. By this strip-shaped edge region of the first carrier material section overlapping strip-shaped portion of the cover is achieved that when applying the einkorn mortar on the horizontal surface of the drainage material no mortar can penetrate into the vertical drainage channels in the abutting surface associated carrier material section.

Der an der von der flüssigkeitsdurchlässigen Abdeckschicht nicht überdeckten streifenförmigen Randbereich anschließende Teilbereich des ersten Trägermaterial-Abschnitts kann in diesem Fall auch ganz entfallen, d. h. der erste Trägermaterial-Abschnitt überdeckt die Auftrittsfläche lediglich in der bereits früher erwähnten Weise im vorderen Randbereich. Die dann in dem an den Randbereich anschließenden Bereich die Drainierung übernehmende, zwischen der Oberfläche der in geeigneter Weise gegen Eindringen von Wasser abgedichteten Auftrittsfläche und dem aufzubringenden Belag liegende Schicht von Einkornmörtel stellt dann den Verbund zwischen dem Belag und Treppenstufe her. Bei dem Aufbringen des Belags wird dann zweckmäßig vor der Aufbringung der noch nicht abgebundenen Einkorn-Mörtelschicht eine dünne Schicht aus einer Kontaktschlämme und auf der Unterseite der anschließend auf der glatt gestrichenen Einkorn-Mörtelschicht aufzubringenden Beläge ebenfalls eine dünne Schicht einer Kontaktschlämme aufgebracht. Dabei entsteht dann ein hochbelastbarer Verbund der Beläge mit der Einkorn-Mörtelschicht und - über diese - mit der Rohbau-Treppenstufe, wodurch die Einbringung einer Bewehrung in die Mörtelschicht entbehrlich werden kann.The partial region of the first carrier material section adjoining the strip-shaped edge region not covered by the liquid-permeable cover layer can in this case also be omitted altogether, ie the first carrier material section covers the tread surface only in the previously mentioned manner in the front edge region. The then in the adjoining the edge region of the drainage taking, between the surface of the suitably sealed against ingress of water tread surface and the applied coating covering layer of Einkornmörtel then establishes the bond between the covering and step. When applying the coating, a thin layer of a contact slurry and then applied on the underside of subsequently applied to the smooth-coated Einkorn mortar layer pads also apply a thin layer of a contact slurry before application of the not yet hardened einkorn mortar layer. This then creates a heavy-duty Bonding of the coverings with the single-grain mortar layer and - via these - with the shell-step, whereby the introduction of a reinforcement in the mortar layer can be dispensable.

Bei der Verlegung von Plattenbelägen auf Treppenstufen kann es zweckmäßig sein, wenn in den Bereichen, in denen Drainagematerial zwischen der Rohbau-Treppenstufe und dem Belag vorgesehen ist, zusätzlich ein gitterartiges Bewehrungsmaterial in die die Beläge haftend mit dem Trägermaterial verbindenden Mörtel- oder Kleberschichten eingebettet wird, um so einer Rissbildung im Plattenbeleg entgegenzuwirken.When laying tile coverings on stairs, it may be useful if in the areas where drainage material is provided between the shell stair step and the covering, in addition, a grid-like reinforcement material in the adhering the coverings with the carrier material bonding mortar or adhesive layers is embedded so as to counteract cracking in the record slip.

Das Bewehrungsmaterial wird dabei bevorzugt von zu einer Gitterstruktur verbundenen metallischen Drähten gebildet. Hierbei werden bevorzugt oberflächenpassivierte, beispielsweise verzinkte Stahldrähten oder Drähte aus korrosionsfestem Stahl verwendet.The reinforcing material is preferably formed by connected to a lattice structure metallic wires. Here, surface-passivated, for example galvanized steel wires or wires made of corrosion-resistant steel are preferably used.

In Figur 1 ist ein Ausführungsbeispiel eines seiner Gesamtheit mit 10 bezeichneten erfindungsgemäßen Drainagematerials dargestellt, welches ein aus einer ursprünglich ebenflächigen dünnen steifen Kunststofffolie hergestelltes profiliertes Trägermaterial 12 aufweist, auf dessen Oberseite nach der Umformung der Kunststofffolie zum dargestellten Trägermaterial 12 eine - in Figur 1 oberhalb des Trägermaterials 12 dargestellte - flüssigkeits- und gasdurchlässige Abdeckbahn 14 haftend aufgebracht ist, welche - im dargestellten Fall aus einem Vliesmaterial besteht, welches also für durchtretendes Wasser bzw. andere Flüssigkeiten durchlässig ist, feste Bestandteile jedoch nach Art einer Filtermatte zurückhält.In FIG. 1 an exemplary embodiment of a drainage material according to the invention designated therein is shown, which has a profiled carrier material 12 produced from an originally planar, thin, rigid plastic film, on the upper side of which, after the plastic film has been formed into the carrier material 12 shown, a FIG. 1 shown above the substrate 12 - liquid and gas-permeable cover 14 is adhesively applied, which - in the case shown consists of a nonwoven material, which is thus permeable to water or other liquids, but retains solid components in the manner of a filter mat.

In die das Trägermaterial 12 bildende Kunststofffolie sind durch entsprechende Warmumformung parallel zueinander verlaufende Entwässerungskanäle 20 eingeformt. Außerdem ist das Trägermaterial durch Umkanten entlang einer quer zur Längserstreckung der Entwässerungskanäle 20 verlaufenden Biege- oder Kantlinie in im Wesentlichen rechtwinklig zueinander verlaufende Trägermaterial-Abschnitte 12a und 12b unterteilt. Der Abschnitt 12a ist entsprechend der Größe und Fläche der Auftrittfläche 24a einer mit dem Drainagematerial 10 zu drainierende Treppenstufe 24 bzw. etwas größer bemessen, während der Abschnitt 12b eine Flächengröße hat, weiche gleich bzw. etwas größer ist, als die die senkrechte Stirntrittfläche 24b der zugehörigen Treppenstufe 24.In which the carrier material 12 forming plastic film are formed by appropriate hot forming parallel drainage channels 20 extending. In addition, the carrier material is divided by edges along a transverse to the longitudinal extent of the drainage channels 20 extending bending or crease line in substantially mutually perpendicular carrier material sections 12a and 12b. The portion 12a is sized according to the size and area of the tread 24a of a drainage material 10 to be drained step 24 or slightly larger, while the portion 12b has an area size that is equal to or slightly greater than that of the vertical Stirntrittfläche 24b of associated step 24.

Das mit der Abdeckbahn 14 als fest haftende Auflage versehene Trägermaterial 12 wird dann in der in Figur 2 und 3 veranschaulichten Weise auf der gegebenenfalls noch mit einer z.B. streichfähigen Abdichtung 26 versehenen oberen Auftrittfläche 24a bzw. Stirntrittfläche 24b haftend aufgebracht, und zwar im dargestellten Fall durch eine dünne auf der Abdichtung aufgetragene Schicht eines Klebers 22, auf welchem die nicht mit der Abdeckbahn 14 belegten Unterseite des Trägermaterials 12 aufgedrückt wird. Auf die trägermaterialabgewandte Außenseite der aus Vliesmaterial bestehenden Abdeckbahn 14 ist eine Schicht 28 eines Klebemörtels aufgetragen, auf welche dann die der Auftrittsfläche 24a bzw. Stoßtrittfläche 24b der Treppenstufe 24 zugeordneten plattenförmigen Beläge 30a bzw. 30b - z. B. in Form von keramischen Fliesen - aufgedrückt werden. Nach dem Abbinden des Klebemörtels 28 sind die Belagplatten 30a und 30b dann fest haftend auf dem seinerseits fest haftend auf der Treppenstufe 24 gehaltene Drainagematerial 10 aufgebracht. Es ist nun klar, dass über die Fugen in den plattenförmigen Belägen 30a durchtretendes Regenwasser ebenso wie beim Abbinden des Klebemörtels austretende Feuchtigkeit über die Entwässerungskanäle 20 abgeführt wird. Bei der Drainierung eines aus einer Mehrzahl von Treppenstufen 24 zusammengesetzte Treppe ist darauf zu achten, dass das Drainagematerial 10 bei allen aufeinander folgenden Treppenstufen so aufgebracht und verlegt wird, dass die Entwässerungskanäle 20 im Trägermaterial 12 der Stufen 24 fluchtend ineinander übergehen. Bei unterschiedlichen Flächengrößen bzw. geometrischen Formen der Auftritt- bzw. Stoßtrittflächen der Treppenstufen 24 müssen die Trägermaterial-Abschnitte 12a bzw. 12b ebenso wie die auf ihnen aufgebrachte Abdeckbahn 14 entsprechend beschnitten werden.The support material 12 provided with the cover sheet 14 as a firmly adhering support is then inserted in the in FIG. 2 and 3 illustrated manner on the optionally still provided with an example spreadable seal 26 upper landing surface 24a or Stirntrittfläche 24b adhesively applied, in the illustrated case by a thin applied to the seal layer of adhesive 22 on which the not covered with the cover 14 underside of the carrier material 12 is pressed. On the carrier material facing away Outside of the cover sheet 14 consisting of nonwoven material, a layer 28 of an adhesive mortar is applied to which then the plate-like coverings 30 a and 30 b assigned to the tread surface 24 a or impact tread surface 24 b of the step 24 - z. B. in the form of ceramic tiles - are pressed. After setting of the adhesive mortar 28, the covering plates 30a and 30b are then applied firmly adhering to the drainage material 10, which in turn is firmly adhered to the step 24. It is now clear that rainwater passing through the joints in the plate-shaped coverings 30a as well as the setting of the adhesive mortar moisture is discharged via the drainage channels 20. During the drainage of a staircase composed of a plurality of steps 24, care must be taken that the drainage material 10 is applied and laid at all successive steps so that the drainage channels 20 in the carrier material 12 of the steps 24 are aligned with one another. In the case of different surface sizes or geometric shapes of the entrance or bump surfaces of the stair steps 24, the carrier material sections 12a and 12b, as well as the cover web 14 applied to them, must be correspondingly trimmed.

Festzuhalten ist noch, dass bei dem in den Figuren 1 und 2 dargestellten Drainagematerial 10 das aus einer profilierten Kunststofffolie bestehende Trägermaterial 12 nur schematisch wiedergegeben ist. In der Praxis können für dieses Trägermaterial 12 profilierte Kunststofffolien verwendet werden, in welchen in den seitlichen Begrenzungswänden der Entwässerungskanälen schlitzartige Durchgangsöffnungen vorgesehen sind, welche zusätzlich die zwischen den in den Zeichnungen dargestellten Entwässerungskanälen 20 liegenden Bereiche als zusätzliche Entwässerungskanäle zur Verfügung stellen. Solche Drainagematerialien in ebenflächiger bahn- oder plattenförmiger Form werden von der Anmelderin z. B. unter der Bezeichnung Watec 4E bzw. auch AquaDrain FE angeboten.It is still to be noted that in the in the Figures 1 and 2 shown drainage material 10 which consists of a profiled plastic film carrier material 12 is shown only schematically. In practice, profiled plastic films can be used for this carrier material 12, in which slot-like passage openings are provided in the lateral boundary walls of the drainage channels, which additionally provide the regions lying between the drainage channels 20 shown in the drawings as additional drainage channels. Such drainage materials in planar web or plate-shaped form are described by the applicant z. B. under the name Watec 4E or AquaDrain FE offered.

In den Figuren 4 und 5 ist eine Anwendung des erfindungsgemäßen Drainagematerials veranschaulicht, bei welcher die auf dem Trägermaterial 12 aufgebrachte Abdeckbahn 14 von einem hochfesten Glas-Gittergewebe gebildet wird, bei welchem die zwischen den das Gitter bildenden sich kreuzenden Glasfasersträngen gebildeten Öffnungen so großflächig sind, dass nicht nur flüssige und gasförmige, sondern auch fließfähige pastöse oder kleinkörnige feste Stoffe hindurch treten können. D.h. auf die Oberseite des Drainagematerials aufgebrachter, fließfähiger Mörtel dringt durch das Gittergewebe 14 hindurch, auch in die oben offenen Entwässerungskanäle 20 und füllt diese vollständig aus, wobei das Gittergewebe nach dem Abbinden oder Aushärten des Mörtels dann in der festen Mörtelschicht im Übergangsbereich zum Trägermaterial formschlüssig verankert ist und außerdem eine Armierungsfunktion für die Mörtelschicht übernimmt. Es ist klar, dass der verwendete Mörtel 28 in diesem Fall im festen oder abgebunden Zustand flüssigkeitsdurchlässig sein muss, um die Entwässerungsfunktion zu gewährleisten. Im dargestellten Anwendungsfall wird deshalb ein so genannter Einkorn- oder Monokornmörtel verwendet, welcher diese Eigenschaft in hinreichendem Maße aufweist.In the FIGS. 4 and 5 an application of the drainage material according to the invention is illustrated, in which the cover sheet 14 applied to the substrate 12 is formed by a high-strength glass mesh in which the openings formed between the glass fiber strands forming the grid are so large that not only liquid and gaseous , but also flowable pasty or small-grained solids can pass through. That is, on the top of the drainage material applied, flowable mortar penetrates through the mesh fabric 14, also in the open-top drainage channels 20 and fills them completely, the mesh fabric after setting or curing of the mortar then in the solid mortar layer in the transition region to the substrate form fit anchored and also takes over a reinforcement function for the mortar layer. It is clear that the mortar 28 used in this case must be permeable to liquid in the solid or set state in order to ensure the dewatering function. In the illustrated application, therefore, a so-called Einkorn- or monocorn mortar is used, which has this property to a sufficient extent.

In Figur 4 ist erkennbar, dass in den, die Entwässerungskanäle 20 seitlich begrenzenden Wandlungsabschnitten des Trägermaterials 12 schlitzartige Durchtrittöffnung 34 vorgesehen sind, so dass über die abgebundene Mörtelschicht 28 in die Entwässerungskanäle 20 geführtes Wasser über die Durchgangsöffnungen 34 durch die seitlichen Wände hindurch treten und in den dann zusätzlich zur Drainierung zur Füge stehenden Zwischenbereichen zwischen den Entwässerungskanälen 20 abgeführt werden kann.In FIG. 4 It can be seen that in the, the drainage channels 20 laterally delimiting conversion sections of the support material 12 slit-like passage opening 34 are provided so that over the hardened mortar layer 28 in the drainage channels 20 guided water via the passage openings 34 through the side walls pass through and then additionally can be removed between the drainage channels 20 for draining intermediate areas intermediate.

Da die verwendeten Einkornmörtel - mit relativ großer Schichtdicke aufgebracht werden, ist in den Figuren 4 und 5 zusätzlich noch in dem oberhalb des Drainagematerials 10 liegenden Bereich der abgebundenen Mörtelschicht eine Armierung 36 aus oberflächenverzinktem Draht oder aus korrosionsfestem Stahldraht dargestellt, welche Rissbildungen im Mörtel und somit dem auf dem Mörtel aufgebrachten Plattenbelag entgegenwirkt.Since the Einkornmörtel used - are applied with relatively large layer thickness is in the FIGS. 4 and 5 additionally shown in the lying above the drainage material 10 area of the set mortar layer, a reinforcement 36 made of galvanized wire or stainless steel wire, which counteracts cracks in the mortar and thus the applied on the mortar plate covering.

Figur 6 und 7 veranschaulicht eine Anwendung des erfindungsgemäßen Drainagematerials, bei welcher der Trägermaterial-Abschnitt 12a des von der profilierten, mit Entwässerungskanälen 20 versehenen Kunststofffolie gebildeten, mit dem flüssigkeits- und gasdurchlässigen Abdeckmaterial 14 aus Vliesmaterial belegten Trägermaterials 12 die Auftrittsfläche 24a der zugehörigen Treppenstufe 24 nur in einem relativ schmalen kantennahen Bereich überdeckt. Der größere, an den Abschnitt 12a anschließende Teil der Auftrittsfläche 24a - bis zur benachbarten Stoßtrittfläche 24b der nächstfolgenden Treppenstufe 24 - wird nicht vom Drainagematerial 10 überdeckt. In diesem Bereich erfolgt die Drainierung, d. h. die Abfuhr von belagsseitig zutretendem Wasser durch eine Schicht aus einem Einkorn- oder Monokornmörtel 28a mit gröberer Körnung des Zuschlag-Splits von z. B. 5-8 mm, welche eine hinreichende Wasserdurchlässigkeit für auch unter ungünstigsten Umständen (z. B. Starkregen) abzuführendem Wasser aufweist. Im kantennahen Bereich der Treppenstufe tritt das anfallende Wasser dann in die Entwässerungskanäle 20 des Trägermaterials 12 über und wird weitgehend über die Entwässerungskanäle in den Trägermaterial-Abschnitten 12a und 12b abgeführt. Das den Abschnitt 12a des Trägermaterials 12 überdeckende Vliesmaterial 14 dient in diesem Bereich weniger der Möglichkeit des Wasserdurchtritts als der Verhinderung des Eindringens von Einkornmörtel 28a in die Entwässerungskanäle 20 im Trägermaterial-Abschnitt 12b bei dessen Aufbringen auf die Auftrittsfläche 24a. Die Schicht des Einkornmörtels 28a ist über die Vorderkante des Trägermaterial-Abschnitts 12b des Trägermaterials 12 herum in den Zwischenraum zwischen dem Trägermaterial-Abschnitt 12b und der zugeordneten, die Stoßtrittfläche 24b abdeckende Platte 30b des Plattenbelags geführt. In diesem Bereich kann ein Monokornmörtel 28b mit geringerer Körnung des Split-Zuschlags von z. B. 2-5 mm verwendet werden, der - bei erhöhter Belastbarkeit - eine etwas geringere Wasserdurchlässigkeit als der auf der Auftrittsfläche verwendete Einkornmörtel 28a aufweist. In diesem Bereich erfolgt die Abfuhr des zutretenden Wassers ja überwiegend über das Drainagematerial 10, d. h. die Entwässerungskanäle 20 im Trägermaterial-Abschnitt 12b. Da hier alle Platten-Beläge 30a und 30b über eine integral zusammenhängende Schicht aus Monokornmörtel 28a, 28b haftend und mit den Treppenstufen verbunden sind, kann in diesem Fall eine gesonderte Bewehrung der Einkorn- oder Monokornmörtel-Schicht entfallen. FIGS. 6 and 7 illustrates an application of the drainage material according to the invention, in which the carrier material portion 12a formed by the profiled, provided with drainage channels 20 plastic film, covered with the liquid and gas-permeable cover material 14 of nonwoven material carrier material 12, the tread surface 24a of the associated step 24 only in a relative narrow edge near area covered. The larger, subsequent to the section 12a part of the tread surface 24a - to the adjacent bump surface 24b of the next step 24 - is not covered by the drainage material 10. In this area, the drainage, ie the removal of water on the side of the inlet occurs through a Layer of a Einkorn- or Monokornmörtel 28a with coarser grain size of the surcharge splits of z. B. 5-8 mm, which has a sufficient water permeability for even under the most unfavorable circumstances (eg heavy rainfall) abzuzuführendem water. In the near-edge region of the step, the accumulated water then passes into the drainage channels 20 of the carrier material 12 and is largely dissipated via the drainage channels in the carrier material sections 12a and 12b. The fleece material 14 covering the portion 12a of the carrier material 12 serves less in this area as a means of permeating the water than preventing penetration of einkornmörtel 28a into the drainage channels 20 in the carrier material portion 12b when it is applied to the tread 24a. The layer of Einkornmörtels 28a is guided over the leading edge of the carrier material portion 12b of the substrate 12 around in the space between the substrate portion 12b and the associated, the bump surface 24b covering plate 30b of the plate covering. In this area, a Monokornmörtel 28b with lower grain size of the split surcharge of z. B. 2-5 mm are used, which - with increased load capacity - has a slightly lower water permeability than the Einkornmörtel 28a used on the tread surface. In this area, the removal of the water to be seized takes place predominantly via the drainage material 10, ie the drainage channels 20 in the carrier material section 12b. Since all plate coverings 30a and 30b are adhesively bonded and connected to the steps via an integrally connected layer of monobore mortar 28a, 28b, in this case a separate reinforcement of the single-grain or mono-grain mortar layer can be dispensed with.

Es ist klar, dass zur Sicherstellung des festen Verbunds zwischen den Belagsplatten 30a und 30b mit der Rohbautreppe vor dem Aufbringen des Monokorn-Mörtels in noch bildsamen Zustand auf die Rohbautreppe eine die Haftung zwischen der Rohbautreppe und der Monokornmörtel-Schicht erhöhende Kontaktschlämme 40 aufgebracht wird. In gleicher Weise wird bei der Verlegung der Belagsplatte 30a bzw. 30b vor deren Aufbringen auf die abgezogene Oberflächen der Einkornmörtel-Schichten 28a, 28b eine dünne Schicht eines Kontaktmörtels 42 als Haftungsvermittler vorgesehen. ,It is clear that in order to ensure the solid bond between the lining plates 30a and 30b with the Rohbautreppe before application of the monograin mortar in the still-plastic state on the Rohbautreppe the adhesion between the Rohbautreppe and the Monokornmörtel layer increasing contact sludge 40 is applied. Similarly, when laying the facing plate 30a or 30b prior to their application to the peeled surfaces of the single grain grout layers 28a, 28b, a thin layer of a contact grout 42 is provided as the adhesion promoter. .

In den Figuren 8 bis 10 ist ein weiteres Ausführungsbeispiel eines in der erfindungsgemäßen Weise ausgebildeten Drainagematerials 10' und dessen Anordnung auf den zu entwässernden Treppenstufen 24 gezeigt, welches dem in Verbindung mit den Figuren 1 bis 3 beschriebenen Drainagematerial 10 ähnlich ist. Abweichend vom Dränagematerial 10 schließt jedoch der der Auftrittsfläche 24a einer Treppenstufe 24 zugeordnete Drainagematerial-Abschnitt 12a des aus einer durch Profilierung mit Entwässerungskanälen 20 versehenen Kunststofffolie hergestellten Trägermaterials 12' nicht am oberen Rand der der Stoßtrittfläche der gleichen Treppenstufe 24 zugeordneten Trägermaterial-Abschnitts 12b der gleichen Treppenstufe sondern am unteren Rand des der Stoßtrittfläche 24b der nächstfolgenden höheren Treppenstufe 24 an. Bei der Verlegung des Drainagematerials 10' dabei die in Richtung der Stufentiefe gemessene Tiefenerstreckung der Trägermaterial-Abschnitte 12a in der in den Figuren 9 und 10 veranschaulichten Weise so gewählt, dass sie in der bestimmungsgemäßen Verlegeposition um das Maß der Stärke des freien oberen Rands des auf der jeweils in Abwärtsrichtung anschließenden Trägermaterial-Abschnitts 12b über die Kante der Treppenstufe vortritt und dadurch die offenen Mündungen von dessen Entwässerungskanälen überdeckt. Zusätzlich kann noch ein Klebeband 46 im Überdeckungsbereich der Trägermaterial-Abschnitte 12a, 12b aufgebracht werden, welches auch die freien Mündungen im Rand des jeweiligen Trägermaterial-Abschnitts 12a gegen das Eindringen des die Haftschicht 28 für die aufzubringenden Plattenbeläge 30a, 30b bildenden Klebemörtels verschließt.In the FIGS. 8 to 10 is a further embodiment of a trained in the manner of the invention drainage material 10 'and its arrangement shown on the steps to be drained 24, which corresponds to the in Connection with the FIGS. 1 to 3 described drainage material 10 is similar. Deviating from the drainage material 10, however, the drainage material section 12a of the support material 12 'made of a plastic film provided with profiling with drainage channels 20 does not close at the upper edge of the support material section 12b of the same stair step 24 assigned to the tread 24a of a step Stair step but at the bottom of the bump surface 24b of the next higher step 24 at. When laying the drainage material 10 'while measured in the direction of the step depth depth extension of the carrier material portions 12a in the in the Figures 9 and 10 illustrated manner selected so that it in the intended laying position by the amount of strength of the free upper edge of the downstream on the respectively subsequent carrier material portion 12b on the edge of the step precedes and thereby covers the open mouths of the drainage channels. In addition, an adhesive tape 46 can also be applied in the covering region of the carrier material sections 12a, 12b, which also closes the free openings in the edge of the respective carrier material section 12a against the penetration of the adhesive layer forming the adhesive layer 28 for the plate coverings 30a, 30b to be applied.

Es ist ersichtlich, dass im Rahmen des Erfindungsgedankens Abwandlungen zur Weiterbildungen der vorstehend beschriebenen Ausführungsbeispiele verwirklichbar sind. So kann das Trägermaterial an Stelle der beschriebenen perforierten Kunststofffolie auch aus bahn- oder plattenförmigem geschlossenzelligem Schaumkunststoff hergestellt sein. Auch die Aufbringung von einzelnen rippenförmigen von einander beabstandeten Trägerelementen aus Schaumkunststoff in paralleler Nebenanordnung auf der Abdeckbahn kommt in Frage. In Sonderfällen, in denen die auf der Auftrittfläche zu verlegenden Plattenbeläge über einen flüssigkeitsdurchlässigen Einkornmörtel entwässert werden, während die stirntrittflächenseitigen Platten durch eine dünne Schicht von Dünnbettmörtel auf dem Drainagematerial 10 aufgebracht werden sollen, kann die aus Vliesmaterial bestehende Abdeckbahn auch lediglich auf dem senkrechten Trägermaterial-Abschnitt 12b vollflächig und einem hieran anschließenden streifenförmigen Bereich des horizontalen Trägermaterial-Abschnitts 12a vorgesehen seien. Dieser schmale auf dem Abschnitt 12a vorgesehene Teilabschnitt der Abdeckbahn 14 verhindert dann beim Aufbringen des Einkornmörtels auf den Abschnitt 12a ein Eindringen des Mörtels in die im Abschnitt 12b gebildeten Entwässerungskanäle 20.It can be seen that within the scope of the inventive concept, modifications to the developments of the embodiments described above can be realized. Thus, instead of the described perforated plastic film, the carrier material can also be made of sheet-like or plate-shaped closed-cell foam plastic. Also, the application of individual rib-shaped spaced-apart support elements of foam plastic in parallel side arrangement on the cover sheet comes into question. In special cases, in which the plate coverings to be laid on the tread surface are dewatered over a liquid-permeable Einkornmörtel while the stirntrittflächenseitigen plates are to be applied by a thin layer of thin-bed mortar on the drainage material 10, which consists of nonwoven material cover also on the vertical Trägermaterial- Section 12b are provided over the entire surface and a subsequent strip-shaped region of the horizontal carrier material portion 12a. This narrow provided on the section 12a portion of the cover 14 then prevents the application of Einkornmörtels penetration of the mortar into the drainage channels 20 formed in section 12b.
