Description

Die Erfindung betrifft einen Bodenablauf zum Abführen von Wasser von einem begehbaren Boden in eine Abwasserleitung, z. B. einen Bodenablauf für eine Dusche.The invention relates to a floor drain for discharging water from a walkable floor into a sewage pipe, e.g. B. a floor drain for a shower.

Derartige Bodenabläufe sind in zahlreichen Ausführungen bekannt. Insbesondere sind derartige Bodenabläufe bekannt, die einen als Geruchverschluss ausgebildeten Ablaufkörper mit einem oberseitig angeordneten, aus dem Ablaufkörper herausnehmbaren, meist quadratischen Einlaufrost aufweisen. Solche Bodenabläufe erfassen einen horizontalen Bereich begrenzter Ausdehnung, wobei der Boden in der Umgebung des Einlaufrostes bzw. der Einlauföffnung des Ablaufkörpers üblicherweise mit das Wasser zum Bodenablauf führendem Gefälle ausgeführt ist. Bei solchen Bodenabläufen wird aufgrund ihrer mehr oder weniger "punktförmigen" Wirkungsweise auch von einer Punktentwässerung gesprochen.Such floor drains are known in numerous designs. In particular, floor drains of this type are known which have a drain body designed as an odor trap with a mostly square inlet grate which is arranged on the top side and can be removed from the drain body. Such floor drains cover a horizontal area of limited extent, with the floor in the vicinity of the inlet grating or the inlet opening of the drain body usually being designed with a gradient leading the water to the floor drain. Such floor drains are also referred to as point drainage due to their more or less "punctiform" mode of action.

Des Weiteren sind Bodenabläufe bekannt, die als sogenannte "Duschrinnen" ausgeführt sind. Diese rinnenförmigen Bodenabläufe erstrecken sich in einer horizontalen Abmessung deutlich weiter als in der senkrechten dazu, wobei das abzuführende Wasser über eine Rinne gesammelt wird. Herkömmliche Duschrinnen weisen einen in den Boden einzubauenden Rinnenkörper auf, in welchem das Wasser gesammelt wird und der oberseitig mit einem länglichen Rost bzw. einer länglichen, einen umlaufenden Einlaufspalt begrenzenden Abdeckung versehen ist. Ferner sind auch Duschrinnen bekannt, bei denen die Rinne nach oben offen ist und über den größten Teil ihrer Längserstreckung ein leicht gemuldetes Rinnenprofil aufweist, das dem Sammeln und Zuführen des Wassers zu einer Ablauföffnung dient. Das oberseitige Profil des Rinnenkörpers bewirkt somit eine oberflächengeführte Punktentwässerung. Der erfindungsgemäße Bodenablauf kann vorzugsweise einen solchen Rinnenkörper umfassen.Furthermore, floor drains are known which are designed as so-called "shower channels". These channel-shaped floor drains extend significantly further in a horizontal dimension than in the vertical dimension, with the water to be drained being collected via a channel. Conventional shower channels have a channel body to be built into the floor, in which the water is collected and which is provided on the upper side with an elongated grate or an elongated cover delimiting a peripheral inlet gap. Furthermore, shower channels are also known in which the channel is open at the top and has a slightly troughed channel profile over most of its longitudinal extent, which is used to collect and feed the water to a drain opening. The upper profile of the channel body thus causes surface-guided point drainage. The floor drain according to the invention can preferably include such a channel body.

Bodenabläufe müssen baulichen Gegebenheiten entsprechend positioniert, befestigt und abgedichtet werden. So kann beispielsweise die gewünschte oder vorgegebene Einbauposition des Bodenablaufs beabstandet von einer Raumwand oder wandbündig an einer Raumwand liegen. Die sichtbaren Enden eines Rinnenkörpers sollten vorzugsweise oder müssen gegebenenfalls mit Fugen von Bodenfliesen fluchten. Die Bauhöhe des Bodenablaufs muss in der Regel an die Höhe von Estrich und Bodenbelag angepasst werden. Der Bodenablauf sollte zuverlässig befestigbar sein, um eine Lageveränderung des Bodenablaufs während der Montage, insbesondere während einer Estrichverlegung oder -auffüllung zu verhindern. Insbesondere muss eine zuverlässige Abdichtung des Bodenablaufs sichergestellt werden, um durch in den Boden eindringende Feuchtigkeit verursachte Bauschäden zu verhindern.Floor drains must be positioned, fastened and sealed according to the structural conditions. For example, the desired or predetermined installation position of the floor drain can be at a distance from a room wall or flush with a room wall. The visible ends of a channel body should preferably or must be flush with the joints of floor tiles. The height of the floor drain usually has to be adjusted to the height of the screed and floor covering. The floor drain should be reliably fastened in order to prevent a change in position of the floor drain during assembly, especially during laying or filling of screed. In particular, reliable sealing of the floor drain must be ensured in order to prevent structural damage caused by moisture penetrating the floor.

Aus der DE 20 2014 007 357 U1 ist ein Bodenablauf der eingangs genannten Art bekannt. Der Bodenablauf hat einen Einlaufrohrstutzen, ein Aufnahmerohr für den Einlaufrohrstutzen, eine flexible Dichtungsmatte, die an dem Aufnahmerohr in einem oberen Bereich des Aufnahmerohres angebracht ist, und eine Abdeckung, unter der die Dichtungsmatte geschützt untergebracht ist. Die Abdeckung schützt die Dichtungsmatte vor mechanischen Beschädigungen und Verschmutzungen. Die Abdeckung ist abnehmbar, um die Dichtungsmatte bei der Montage des Bodenablaufs auf dem Boden aufbringen zu können. Der aus der DE 20 2014 007 357 U1 bekannte Bodenablauf scheint noch verbesserungsfähig.From the DE 20 2014 007 357 U1 a floor drain of the type mentioned is known. The floor drain has a spigot, a spigot receiving tube, a flexible sealing mat attached to the spigot at an upper portion of the spigot, and a cover under which the sealing mat is protected. The cover protects the sealing mat from mechanical damage and dirt. The cover is removable in order to be able to apply the sealing mat to the floor when installing the floor drain. The one from the DE 20 2014 007 357 U1 well-known floor drain still seems to be in need of improvement.

Die EP 2 322 725 A zeigt einen Ablaufsiphon für einen darüber angeordneten Abfluss, wobei der Ablaufsiphon mit einem wasserdichten Gewebe ausgestattet und mit Kies bedeckt ist. Der mit Kies bedeckte Ablaufsiphon erlaubt den Umlauf des aus dem Abfluss überlaufenden Wassers und umfasst des Weiteren ein länglich eingekerbtes Gehäuse, das an einer Ausgangsöffnung des Abflusses bzw. eines zusätzlichen, an dem Abfluss angeschlossenen Rohres angebracht ist.the EP 2 322 725 A shows a drain siphon for an overhead drain, the drain siphon being fitted with a waterproof fabric and covered with gravel. The gravel-covered drain siphon allows circulation of the water overflowing from the drain and further includes a longitudinally indented housing attached to an outlet opening of the drain or an additional pipe connected to the drain.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Bödenablauf der eingangs genannten Art zu schaffen, der hinsichtlich der Einfachheit und Sicherheit der Montage weiter verbessert ist.The present invention is based on the object of creating a floor drain of the type mentioned at the outset, which is further improved with regard to the simplicity and safety of assembly.

Diese Aufgabe wird gelöst durch einen Bodenablauf mit den in Anspruch 1 angegebenen Merkmalen. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Bodenablaufs sind in den Unteransprüchen angegeben.This object is achieved by a floor drain having the features specified in claim 1. Advantageous configurations of the floor drain according to the invention are specified in the dependent claims.

Der erfindungsgemäße Bodenablauf weist auf: Einen Einlaufkanalstutzen, einen ersten Aufnahmekörper für den Einlaufkanalstutzen, einen zweiten Aufnahmekörper für den ersten Aufnahmekörper und ein dem zweiten Aufnahmekörper in Wasserabführrichtung nachfolgendes Ablaufgehäuse, das vorzugsweise als Geruchverschluss ausgeführt ist, wobei der erste Aufnahmekörper einen schalenförmigen Abschnitt aufweist, an dessen Außenrand eine flexible Dichtungsmatte flüssigkeitsdicht angeschlossen ist und dessen Boden in einen ersten Ablaufstutzen übergeht, der in den zweiten Aufnahmekörper einsetzbar ist, wobei der zweite Aufnahmekörper einen schalenförmigen Abschnitt aufweist, an dem ein nach außen vorstehender Flansch angeformt oder angebracht ist, und wobei der schalenförmige Abschnitt des zweiten Aufnahmekörpers in einen zweiten Ablaufstutzen übergeht.The floor drain according to the invention has: An inlet duct socket, a first receiving body for the inlet duct socket, a second receiving body for the first receiving body and a drain housing which follows the second receiving body in the water discharge direction and is preferably designed as an odor trap, with the first receiving body having a bowl-shaped section the outer edge of which is connected in a liquid-tight manner to a flexible sealing mat and the bottom of which merges into a first drain socket which can be inserted into the second receiving body, the second receiving body having a bowl-shaped section on which an outwardly projecting flange is formed or attached, and the bowl-shaped Section of the second receiving body merges into a second outlet pipe.

Durch die Unterteilung des Bodenablaufs in einen Einlaufkanalstutzen, einen ersten Aufnahmekörper für den Einlaufkanalstutzen, einen zweiten Aufnahmekörper für den ersten Aufnahmekörper und ein dem zweiten Aufnahmekörper in Wasserabführrichtung nachfolgendes Ablaufgehäuse lassen sich eine optimale Anpassung des Bodenablaufs an die Höhe von Estrich und Bodenbelag sowie eine einfache Feinjustierung des sichtbaren Ablaufabschnitts, vorzugsweise eines Rinnenkörpers, relativ zu angrenzenden Fugen des Bodenbelages erzielen. Der Einlaufkanalstutzen kann dabei insbesondere auch als Höhenausgleichsstück verwendet und - sofern erforderlich - an die Höhe oder Dicke des Bodenbelages, z. B. die Fliesenhöhe angepasst werden. Der an den schalenförmigen Abschnitt des zweiten Aufnahmekörpers angeformte oder angebrachte Flansch ermöglicht eine zuverlässige Befestigung des Bodenablaufs, so dass seine Einbaulage während nachfolgender Montageschritte fest gesichert ist. Der Flansch weist hierzu vorzugsweise mehrere Ausnehmungen auf, durch die fließfähiger Estrich oder Kleber den Flansch durchdringen kann, so dass der Flansch und damit der Bodenablauf nach Aushärtung des Estrichs bzw. Klebers in diesem fest verankert sind. Der Flansch kann zusammen mit dem schalenförmigen Abschnitt des zweiten Aufnahmekörper auch als Einlaufflansch bezeichnet werden.The subdivision of the floor drain into an inlet duct socket, a first receiving body for the inlet duct socket, a second receiving body for the first receiving body and a drain housing following the second receiving body in the direction of water drainage allows the floor drain to be optimally adapted to the height of the screed and floor covering as well as simple fine adjustment of the visible drain section, preferably a channel body, relative to adjacent joints of the floor covering. The inlet duct socket can in particular also be used as a height adjustment piece and - if necessary - adapted to the height or thickness of the floor covering, e.g. B. the tile height can be adjusted. The flange formed or attached to the shell-shaped section of the second receiving body enables the floor drain to be reliably fastened, so that its installation position is firmly secured during subsequent assembly steps. For this purpose, the flange preferably has a plurality of recesses through which free-flowing screed or adhesive can penetrate the flange, so that the flange and thus the floor drain are firmly anchored in the screed or adhesive after it has hardened. The flange can together can also be referred to as the inlet flange with the shell-shaped section of the second receiving body.

Die am schalenförmigen Abschnitt des ersten Aufnahmekörpers flüssigkeitsdicht angeschlossene flexible Dichtungsmatte ermöglicht jeweils eine einfache und zuverlässige Abdichtung des Bodenablaufs an dessen Umgebung bei unterschiedlichen Einbausituationen, insbesondere bei einer wandbündigen Positionierung des Bodenablaufs. Die flexible Dichtungsmatte mit dem schalenförmigen Abschnitt des zugehörigen Aufnahmekörpers können zusammen auch als Abdichtungsmanschette bezeichnet werden. Die Dichtungsmatte weist in ihrem Rand oder in ihren Randecken vorzugsweise Löcher auf, um eine formschlüssige Verbindung der Dichtungsmatte mit einem auf dem Estrich oder einer Wand aufgebrachten Klebematerial und/oder einer sogenannten Flüssigfolie zu erzielen.The flexible sealing mat connected in a liquid-tight manner to the shell-shaped section of the first receiving body enables simple and reliable sealing of the floor drain to its surroundings in different installation situations, in particular when the floor drain is positioned flush with the wall. The flexible sealing mat with the shell-shaped section of the associated receiving body can also be referred to as a sealing collar. The sealing mat preferably has holes in its edge or in its edge corners in order to achieve a form-fit connection of the sealing mat with an adhesive material applied to the screed or a wall and/or a so-called liquid film.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass der erste Ablaufstutzen eine an seinem Außenumfang angeordnete Ringdichtung aufweist. Hierdurch lässt sich eine sehr sichere sowie einfach herzustellende Abdichtung des Bodenablaufs erzielen. Als Ringdichtung wird vorzugsweise ein O-Ring verwendet, der in eine am Außenumfang des ersten Ablaufstutzens ausgebildete Ringnut eingesetzt wird.An advantageous embodiment of the invention is characterized in that the first outlet socket has an annular seal arranged on its outer circumference. As a result, a very reliable and easy to produce sealing of the floor drain can be achieved. An O-ring is preferably used as the annular seal, which is inserted into an annular groove formed on the outer circumference of the first outlet connection.

Nach einer weiteren vorteilhafte Ausgestaltung der Erfindung sind der schalenförmige Abschnitt des ersten Aufnahmekörpers und der schalenförmige Abschnitt des zweiten Aufnahmekörpers mit einander zugeordneten Rastelementen versehen, die bei einer Anordnung des schalenförmigen Abschnitts des ersten Aufnahmekörpers in dem schalenförmigen Abschnitt des zweiten Aufnahmekörpers miteinander verrastbar sind bzw. verrasten. Die Rastelemente des schalenförmigen Abschnitts des ersten Aufnahmekörpers sind beispielsweise in Form von Rastfedern oder Rastnasen ausgeführt, die auch als Clipsecken bezeichnet werden können. Durch die Rastverbindung des schalenförmigen Abschnitts des ersten Aufnahmekörpers mit dem schalenförmigen Abschnitt des zweiten Aufnahmekörpers wird die Abdichtung zwischen Flansch (Einlaufflansch) und Dichtungsmatte (Abdichtungsmanschette) sicher vorgegeben. Ein Vorteil, den der Installateur bzw. Fliesenleger zu schätzen wissen wird. Das eine sichere Abdichtung bedeutende Einrasten lässt sich bei der Montage der Dichtungsmatte an dem Flansch akustisch und/oder optisch gut wahrnehmen.According to a further advantageous embodiment of the invention, the shell-shaped section of the first receiving body and the shell-shaped section of the second receiving body are provided with mutually associated latching elements which can be latched or latch with one another when the shell-shaped section of the first receiving body is arranged in the shell-shaped section of the second receiving body . The latching elements of the shell-shaped section of the first receiving body are designed, for example, in the form of latching springs or latching lugs, which can also be referred to as clip corners. By the locking connection of the shell-shaped portion of the first receiving body with The sealing between the flange (inlet flange) and the sealing mat (sealing sleeve) is reliably specified for the shell-shaped section of the second receiving body. An advantage that the installer or tiler will appreciate. The snapping in, which is important for a secure seal, can be clearly perceived acoustically and/or visually when the sealing mat is installed on the flange.

Vorzugsweise weisen der schalenförmige Abschnitt des ersten Aufnahmekörpers und der schalenförmige Abschnitt des zweiten Aufnahmekörpers mindestens vier Paare einander zugeordneter Rastelemente auf, die bei einer Anordnung des schalenförmigen Abschnitts des ersten Aufnahmekörpers in dem schalenförmigen Abschnitt des zweiten Aufnahmekörpers miteinander verrastbar sind, wobei vier der Rastelemente an entgegengesetzten Außenseiten des schalenförmigen Abschnitts des ersten Aufnahmekörpers angeordnet sind.The shell-shaped section of the first receiving body and the shell-shaped section of the second receiving body preferably have at least four pairs of mutually associated latching elements which can be latched together when the shell-shaped section of the first receiving body is arranged in the shell-shaped section of the second receiving body, four of the latching elements being on opposite sides Outsides of the cup-shaped portion of the first receiving body are arranged.

Bevorzugt weisen die schalenförmigen Abschnitte der beiden Aufnahmekörper jeweils einen umlaufenden Absatz auf, der einen mit Gefälle ausgebildeten Boden mit einer kreisförmigen Ablauföffnung umrahmt. Vorzugsweise ist die kreisförmige Ablauföffnung mittig angeordnet, wobei der Boden nach Art eines Trichters mindestens zwei an der Ablauföffnung endende Gefälleflächen aufweist.Preferably, the shell-shaped sections of the two receiving bodies each have a circumferential shoulder which frames a base designed with a gradient and having a circular drainage opening. The circular drainage opening is preferably arranged in the center, with the base having at least two sloping surfaces ending at the drainage opening in the manner of a funnel.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Bodenablaufs sieht vor, dass der schalenförmige Abschnitt des ersten Aufnahmekörpers größer bemessen ist als der Einlaufkanalstutzen, so dass der Einlaufkanalstutzen relativ zu dem schalenförmigen Abschnitt des ersten Aufnahmekörpers horizontal verschiebbar in dem schalenförmigen Abschnitt aufgenommen ist. Vorzugsweise ist der Einlaufkanalstutzen in mindestens zwei quer zueinander verlaufenden Richtungen horizontal verschiebbar in dem schalenförmigen Abschnitt des ersten Aufnahmekörpers aufgenommen. Somit lassen sich Passungenauigkeiten bei der Montage des Bodenablaufs durch horizontales Verschieben des Einlaufkanalstutzens relativ zu dem schalenförmigen Abschnitt des ersten Aufnahmekörpers (Abdichtungsmanschette) in einem gewissen Anpassungsspielraum ausgleichen.A further advantageous embodiment of the floor drain according to the invention provides that the shell-shaped section of the first receiving body is dimensioned larger than the inlet duct socket, so that the inlet duct socket is accommodated in the shell-shaped section so that it can be displaced horizontally relative to the shell-shaped section of the first receiving body. Preferably, the inlet channel socket is accommodated in the shell-shaped section of the first receiving body so that it can be displaced horizontally in at least two directions running transversely to one another. This means that fitting inaccuracies when installing the floor drain can be eliminated by moving the inlet channel socket horizontally compensate relative to the shell-shaped portion of the first receiving body (sealing sleeve) in a certain adjustment range.

Vorzugsweise weist der insbesondere als Höhenausgleichsstück dienende Einlaufkanalstutzen an seinem Außenumfang eine oder mehrere umlaufende Rillen auf, von denen jede als Führung für ein Schneidwerkzeug, z. B. ein Messer, für ein Kürzen des Einlaufkanalstutzens genutzt werden kann. Die jeweilige Rille kann auch als Schneidrille bezeichnet werden. Beispielsweise kann der Einlaufkanalstutzen eine Höhe im Bereich von ca. 15 bis 50 mm, vorzugsweise 15 bis 35 mm, und dabei eine Anzahl von parallelen, umlaufenden Rillen im Bereich von 3 bis 10, vorzugsweise im Bereich von 5 bis 8 Rillen (Schneidrillen) aufweisen. Vorzugsweise ist die Wanddicke des Einlaufkanalstutzens am Grund der Rille deutlich geringer als neben dem Rillengrund und weist abschnittsweise Lochperforationen auf, was ein Kürzen des Einlaufkanalstutzens erleichtert.Preferably, the inlet channel connecting piece, which serves in particular as a height adjustment piece, has one or more circumferential grooves on its outer circumference, each of which serves as a guide for a cutting tool, e.g. B. a knife can be used for shortening the inlet duct socket. The respective groove can also be referred to as a cutting groove. For example, the inlet channel socket can have a height in the range from about 15 to 50 mm, preferably 15 to 35 mm, and a number of parallel, circumferential grooves in the range from 3 to 10, preferably in the range from 5 to 8 grooves (cutting grooves). . The wall thickness of the inlet channel socket is preferably significantly less at the base of the groove than next to the groove base and has perforations in sections, which makes it easier to shorten the inlet channel socket.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Flansch des schalenförmigen Abschnitts (Einlaufflansch) des zweiten Aufnahmekörpers mindestens eine Rille auf, die parallel zu einem Rand des schalenförmigen Abschnitts des zweiten Aufnahmekörpers verläuft, wobei die Rille nicht mehr als 10 mm, vorzugsweise weniger als 5 mm von dem Rand des schalenförmigen Abschnitts beabstandet ist. Auch diese Rille dient als Schneidrille. Vorzugsweise ist die Wanddicke des Flansches am Grund der Rille deutlich geringer als neben dem Rillengrund, was ein Abtrennen eines bestimmten Flanschbereichs erleichtert. Durch das Abtrennen eines bestimmten Flanschbereichs kann der Bodenablauf näher oder direkt an eine Raumwand einer Nasszelle bzw. Dusche angesetzt werden. Somit lässt sich der Bodenablauf wahlweise an verschiedenen Positionen einer Nasszellenbodenfläche anordnen. Beispielsweise lässt sich der erfindungsgemäße Bodenablauf beabstandet von der Wand einer Duschzelle mittig oder dezentral in der Bodenfläche der Duschzelle oder direkt an der Wand einer Duschzelle positionieren.According to a further advantageous embodiment of the invention, the flange of the bowl-shaped section (inlet flange) of the second receiving body has at least one groove which runs parallel to an edge of the bowl-shaped section of the second receiving body, the groove being no more than 10 mm, preferably less than 5 mm from the edge of the bowl-shaped section. This groove also serves as a cutting groove. The wall thickness of the flange at the bottom of the groove is preferably significantly less than next to the bottom of the groove, which makes it easier to cut off a specific flange area. By cutting off a specific flange area, the floor drain can be attached closer or directly to the wall of a wet cell or shower. Thus, the floor drain can be optionally arranged at different positions of a wet cell floor area. For example, the floor drain according to the invention can be positioned at a distance from the wall of a shower cell in the middle or decentralized in the floor area of the shower cell or directly on the wall of a shower cell.

Der schalenförmige Abschnitt des zweiten Aufnahmekörpers und dessen Flansch sind vorzugsweise länglich ausgebildet, wobei der schalenförmige Abschnitt sowie der Flansch zwei zueinander parallele Längsabschnitte aufweisen, die miteinander durch zwei kürzere, zueinander parallele Querabschnitte verbunden sind. Der jeweilige Längsabschnitt kann beispielsweise ca. doppelt so lang sein als der jeweilige Querabschnitt des Flansches. Vorzugsweise verlaufen die parallelen Längsabschnitte im Wesentlichen rechtwinklig zu den parallelen Querabschnitten.The shell-shaped section of the second receiving body and its flange are preferably elongate, with the shell-shaped section and the flange having two longitudinal sections parallel to one another, which are connected to one another by two shorter, parallel transverse sections. The respective longitudinal section can, for example, be approximately twice as long as the respective transverse section of the flange. Preferably, the parallel longitudinal sections are substantially perpendicular to the parallel transverse sections.

Zwischen dem schalenförmigen Abschnitt des zweiten Aufnahmekörpers und dessen Flansch ist vorzugsweise ein nach oben vorstehender Steg ausgebildet, der vorzugsweise als geschlossener Steg ausgeführt ist. Die mindestens eine Rille (Schneidrille) verläuft beispielsweise zumindest in einem der Längsabschnitte des Flansches, direkt entlang des Steges. Vorzugsweise sind auch der andere Längsabschnitt und die beiden zueinander parallelen Querabschnitte des Flansches jeweils mit mindestens einer Rille (Schneidrille) versehen, wobei sich die Rillen im Verbindungsbereich der Längs- und Querabschnitte kreuzen und sich vorzugsweise bis zum Außenumfang des Flansches erstrecken.Between the shell-shaped section of the second receiving body and its flange there is preferably an upwardly projecting web which is preferably designed as a closed web. The at least one groove (cutting groove) runs, for example, at least in one of the longitudinal sections of the flange, directly along the web. Preferably, the other longitudinal section and the two mutually parallel transverse sections of the flange are each provided with at least one groove (cutting groove), the grooves crossing in the connecting area of the longitudinal and transverse sections and preferably extending to the outer circumference of the flange.

Hinsichtlich einer perfekten Ausrichtung des im fertig eingebauten Zustand des Bodenablaufs noch sichtbaren, die Wassereinlauföffnung aufweisenden Teils des Bodenablaufs ist es vorteilhaft, wenn nach einer weiteren Ausgestaltung der Erfindung der zweite Aufnahmekörper in flüssigkeitsdichter Verbindung mit dem Ablaufgehäuse relativ zu dem Ablaufgehäuse um eine vertikale Achse drehbar ist. Somit kann der Flansch (Einlaufflansch) des zweiten Aufnahmekörper im Wesentlichen unabhängig von der Ausrichtung des Ablaufgehäuses gedreht und somit relativ zu einer angrenzenden Wand einer Duschzelle optimal ausgerichtet werden.With regard to a perfect alignment of the part of the floor drain that has the water inlet opening and is still visible in the fully installed state of the floor drain, it is advantageous if, according to a further embodiment of the invention, the second receiving body in liquid-tight connection with the drain housing can be rotated relative to the drain housing about a vertical axis . The flange (inlet flange) of the second receiving body can thus be rotated essentially independently of the orientation of the drain housing and thus optimally aligned relative to an adjacent wall of a shower cubicle.

Ferner kann der erfindungsgemäße Bodenablauf einen Bauschutzdeckel zur vollständigen Abdeckung des schalenförmigen Abschnitts des zweiten Aufnahmekörpers beinhalten, wobei der Bauschutzdeckel formschlüssig sowie lösbar mit dem Rand des schalenförmigen Abschnitts des zweiten Aufnahmekörpers verbunden ist. Durch den Bauschutzdeckel kann insbesondere ein Eindringen von Estrichmasse in das Ablaufgehäuse während des Einbaus des Bodenablaufs zuverlässig verhindert werden.Furthermore, the floor drain according to the invention can contain a protective cover for completely covering the shell-shaped section of the second receiving body, the protective cover being positively and detachably connected to the edge of the shell-shaped section of the second receiving body connected is. The protection cover can in particular reliably prevent screed from penetrating into the drain housing during the installation of the floor drain.

Eine weitere Ausgestaltung des erfindungsgemäßen Bodenablaufs sieht vor, dass der Einlaufkanalstutzen oberseitig einen Verbindungsabschnitt zur formschlüssigen und/oder flüssigkeitsdichten Anbindung eines Wassersammelmittels, vorzugsweise eines länglichen Wassersammelkörpers mit Mehrfachgefälle, aufweist, wobei das Wassersammelmittel oder der Wassersammelkörper eine Öffnung enthält, durch die gesammeltes Wasser abfließen kann.A further embodiment of the floor drain according to the invention provides that the inlet channel socket has a connecting section on the upper side for the form-fitting and/or liquid-tight connection of a water-collecting means, preferably an elongate water-collecting body with multiple gradients, with the water-collecting means or the water-collecting body having an opening through which the collected water can flow out .

Ferner kann der erfindungsgemäße Bodenablauf ein solches Wassersammelmittel, vorzugsweise in Form eines länglichen Wassersammelkörpers mit Mehrfachgefälle umfassen, wobei das Wassersammelmittel oder der Wassersammelkörper eine Öffnung, vorzugsweise eine spaltförmige Öffnung aufweist, durch die gesammeltes Wasser abfließen kann. Das oberseitige Profil des Wassersammelkörpers ist vorzugsweise für eine oberflächengeführte Punktentwässerung ausgebildet. Das Gefälle des Wassersammelkörpers kann dabei beispielsweise im Bereich von ca. 1 bis 3 % liegen.Furthermore, the floor drain according to the invention can include such a water-collecting means, preferably in the form of an elongated water-collecting body with multiple gradients, the water-collecting means or the water-collecting body having an opening, preferably a slit-shaped opening, through which the collected water can flow out. The top profile of the water collection body is preferably designed for surface-guided point drainage. The gradient of the water-collecting body can be in the range of about 1 to 3%, for example.

Nach einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Bodenablaufs ist der schalenförmige Abschnitt des ersten Aufnahmekörpers mit einem Siebeinsatz versehen. Hierdurch können gröbere Partikel und/oder Haare, welche die Einlauföffnung passiert haben, aufgefangen werden, so dass sie nicht in das Ablaufgehäuse bzw. den Geruchverschluss gelangen.According to a further advantageous embodiment of the floor drain according to the invention, the shell-shaped section of the first receiving body is provided with a filter insert. As a result, coarser particles and/or hair that have passed through the inlet opening can be caught so that they do not get into the drain housing or the odor trap.

Eine weitere vorteilhafte Ausgestaltung des erfindungsgemäßen Bodenablaufs sieht vor, dass das Wassersammelmittel bzw. der längliche Wassersammelkörper oberhalb des schalenförmigen Abschnitts des zweiten Aufnahmekörpers eine Einlegeraufnahme mit einem darin formschlüssig aufgenommenen Einleger aufweist, wobei der Einleger die Öffnung (Einlauföffnung), vorzugsweise die spaltförmigeA further advantageous embodiment of the floor drain according to the invention provides that the water collecting means or the elongate water collecting body has an insert receptacle above the shell-shaped section of the second receiving body with an insert accommodated in a form-fitting manner, the insert having the opening (inlet opening), preferably the slot-shaped one

Öffnung aufweist, durch die gesammeltes Wasser abfließen kann. Nach Entnahme des Einlegers ist der schalenförmige Abschnitt des ersten Aufnahmekörpers für Reinigungszwecke, insbesondere für eine Entnahme und Reinigung des Siebeinsatzes zugänglich. Der Einleger kann auch als Rost bezeichnet werden und mehrere Öffnungen aufweisen.Has opening through which collected water can drain. After the insert has been removed, the shell-shaped section of the first receiving body is accessible for cleaning purposes, in particular for removing and cleaning the filter insert. The insert can also be referred to as a grate and can have several openings.

Der in der Zeichnung gezeigte Bodenablauf 1 dient zum Abführen von Wasser von einem begehbaren Boden in eine Abwasserleitung. Der Bodenablauf 1 umfasst einen Einlaufkanalstutzen 2, einen ersten oder oberen Aufnahmekörper 3 für den Einlaufkanalstutzen 2, einen zweiten oder unteren Aufnahmekörper 4 für den ersten oder oberen Aufnahmekörper 3 und ein dem zweiten oder unteren Aufnahmekörper 4 in Wasserabführrichtung nachfolgendes Ablaufgehäuse 5, das vorzugsweise als Geruchverschluss ausgeführt ist.The floor drain 1 shown in the drawing is used to drain water from a walk-in floor into a sewer. The floor drain 1 comprises an inlet channel socket 2, a first or upper receiving body 3 for the inlet channel socket 2, a second or lower receiving body 4 for the first or upper receiving body 3 and a drain housing 5 following the second or lower receiving body 4 in the water discharge direction, which is preferably used as an odor trap is executed.

Der erste Aufnahmekörper 3 weist einen schalenförmigen Abschnitt 3.1 auf, an dessen Außenrand eine flexible Dichtungsmatte (Abdichtungsmembran) 3.2 flüssigkeitsdicht angeschlossen ist und dessen Boden in einen Ablaufstutzen 3.3 übergeht (vgl. Fig. 7), der in den zweiten Aufnahmekörper 4 einsetzbar ist. Der zweite Aufnahmekörper 4 weist einen schalenförmigen Abschnitt 4.1 auf, an dem ein nach außen vorstehender Flansch 4.2 angebracht, vorzugsweise angeformt ist, wobei der schalenförmige Abschnitt 4.1 in einen zweiten Ablaufstutzen 4.3 übergeht.The first receiving body 3 has a shell-shaped section 3.1, to the outer edge of which a flexible sealing mat (sealing membrane) 3.2 is connected in a liquid-tight manner and the bottom of which merges into a drain socket 3.3 (cf. 7 ), which can be inserted into the second receiving body 4. The second receiving body 4 has a shell-shaped section 4.1, to which an outwardly projecting flange 4.2 is attached, preferably formed, with the shell-shaped section 4.1 merging into a second outlet port 4.3.

Der Einlaufkanalstutzen 2 weist oberseitig einen Verbindungsabschnitt 2.1 zur formschlüssigen und/oder flüssigkeitsdichten Anbindung eines Wassersammelmittels, vorzugsweise eines länglichen Wassersammelkörpers 6 mit Mehrfachgefälle auf. Der längliche Wassersammelkörper 6, der auch als Duschrinne bezeichnet werden kann, weist oberhalb des schalenförmigen Abschnitts 4.1 des zweiten Aufnahmekörpers 4 eine als Einlegeraufnahme ausgebildete Öffnung 6.1 auf, in welcher ein Einleger 6.2 formschlüssig aufgenommen und gehalten ist. Der austauschbare Einleger 6.2 weist mindestens eine Öffnung 6.21, vorzugsweise eine spaltförmige Öffnung 6.21 auf, durch die mittels des Wassersammelkörpers 6 gesammeltes Wasser abfließen kann. Zur vertikalen Halterung des Einlegers 6.2 ist die Einlegeraufnahme an ihrem Innenumfang mit mindestens zwei gegenüberliegenden Absätzen oder einem umlaufenden Absatz (nicht gezeigt) versehen, auf denen bzw. auf dem der Einleger 6.2 aufliegt. Die Oberseite des in die Einlegeraufnahme eingesetzten Einlegers 6.2 schließt vorzugsweise flächenbündig mit der Oberfläche des Wassersammelkörpers 6 ab. Der rinnenartige Wassersammelkörper 6 weist ein von seinem jeweiligen schmalen Stirnende 6.3 in Richtung der Einlegeraufnahme 6.1 verlaufendes relativ geringes Gefälle 6.4 auf, das vorzugsweise im Bereich von ca. 1 bis 3 %, besonders bevorzugt im Bereich von ca. 1 bis 2 % liegt. Zudem weist der Wassersammelkörper 6 an seiner Oberseite ein konkaves oder muldenförmiges Querschnittsprofil auf, wobei die Höhe der seitlichen Flanken 6.5 des Querschnittsprofils von dem jeweiligen schmalen Stirnende 6.3 in Richtung der Einlegeraufnahme 6.1 zunimmt. Es ergibt sich somit ein Mehrfachgefälle, wobei das Oberflächenprofil des Wassersammelkörpers 6 eine oberflächengeführte Entwässerung bewirkt. Der Wassersammelkörper 6 und der Einleger 6.2 sind vorzugsweise aus rostfreiem Stahl hergestellt.The inlet channel socket 2 has a connecting section 2.1 on the upper side for the form-fitting and/or liquid-tight connection of a water-collecting means, preferably an elongate water-collecting body 6 with multiple gradients. The elongate water collection body 6, which can also be referred to as a shower channel, has above the shell-shaped section 4.1 of the second receiving body 4 an opening 6.1 designed as an insert receptacle, in which an insert 6.2 is positively received and held. The replaceable insert 6.2 has at least one opening 6.21, preferably a slit-shaped opening 6.21, through which the water collected by the water collecting body 6 can flow off. In order to hold the insert 6.2 vertically, the insert receptacle is provided on its inner circumference with at least two opposing shoulders or a peripheral shoulder (not shown), on which the insert 6.2 rests. The upper side of the insert 6.2 inserted into the insert receptacle is preferably flush with the surface of the water collecting body 6. The channel-like water-collecting body 6 has a relatively slight gradient 6.4 running from its respective narrow front end 6.3 in the direction of the insert receptacle 6.1, which is preferably in the range of approximately 1 to 3%, particularly preferably in the range of approximately 1 to 2%. In addition, the water collecting body 6 has a concave or trough-shaped cross-sectional profile on its upper side, with the height of the side flanks 6.5 of the cross-sectional profile increasing from the respective narrow front end 6.3 in the direction of the insert receptacle 6.1. This results in a multiple gradient, with the surface profile of the water collecting body 6 being surface-guided causes drainage. The water collecting body 6 and the insert 6.2 are preferably made of stainless steel.

Das Ablaufgehäuse 5 weist einen vertikalen Rohrstutzen (Eingangsstutzen) 5.1 und einen beispielsweise horizontal verlaufenden Ablaufstutzen (Ausgangsstutzen) 5.2 auf. Der vertikale Rohrstutzen 5.1 und der an eine Abwasserleitung (nicht gezeigt) anzuschließende Ablaufstutzen 5.2 sind über einen S-förmigen Kanalabschnitt 5.3 miteinander verbunden. Der S-förmige Kanalabschnitt 5.3 ergibt zusammen mit dem vertikalen Rohrstutzen 5.1 einen Geruchverschluss, in welchen im Gebrauch des Bodenablaufs 1 Sperrwasser in einer bestimmten Höhe von beispielsweise ca. 50 mm ansteht.The drain body 5 has a vertical pipe socket (inlet socket) 5.1 and a drain socket (outlet socket) 5.2 running horizontally, for example. The vertical pipe socket 5.1 and the drain socket 5.2 to be connected to a sewage pipe (not shown) are connected to one another via an S-shaped channel section 5.3. The S-shaped channel section 5.3, together with the vertical pipe socket 5.1, results in an odor trap in which, when the floor drain 1 is in use, sealing water is present at a certain height of, for example, approximately 50 mm.

Der vertikale Rohrstutzen 5.1 ist am oberen Ende mit einer Ringdichtung 5.4 versehen, die den in den Rohrstutzen 5.1 eingesteckten Ablaufstutzen 4.3 des Aufnahmekörpers 4 flüssigkeitsdicht abdichtet. Der Aufnahmekörper 4 ist dabei relativ zu dem Ablaufgehäuse 5 um eine vertikale Achse drehbar. Bei Bedarf kann der Rohrstutzen 5.1 bzw. der Ablaufstutzen 4.3 durch ein optionales Rohr (nicht gezeigt) verlängert werden, um gegebenenfalls größere Bauhöhen realisieren zu können.The vertical pipe socket 5.1 is provided at the upper end with an annular seal 5.4, which seals the plugged into the pipe socket 5.1 drain socket 4.3 of the receiving body 4 liquid-tight. The receiving body 4 can be rotated about a vertical axis relative to the drain housing 5 . If necessary, the pipe socket 5.1 or the drain socket 4.3 can be lengthened by an optional pipe (not shown) in order to be able to achieve greater overall heights if necessary.

Der schalenförmige Abschnitt 4.1 des Aufnahmekörpers 4 und dessen Flansch 4.2 sind länglich ausgebildet, wobei der schalenförmige Abschnitt 4.1 und der Flansch 4.2 zwei zueinander parallele Längsabschnitte 4.21 aufweisen, die miteinander durch zwei kürzere, zueinander parallele Querabschnitte 4.22 verbunden sind. Die Länge des schalenförmigen Abschnitts 4.1 misst beispielsweise in etwa das Zweifache seiner Breite. Die parallelen Längsabschnitte 4.21 des Flansches verlaufen im Wesentlichen rechtwinklig zu den parallelen Querabschnitten 4.22 des Flansches. Der Flansch 4.2 ist mit mehreren Ausnehmungen, vorzugsweise Löchern 4.4 versehen, die der Verankerung des Aufnahmekörpers 4 in einer Estrichmasse dienen, mit der das auf einem Rohboden positionierte Ablaufgehäuse 5 während eines nachfolgenden Montageschrittes umgossen wird. Der Flansch 4.2 stellt somit einen Ausnehmungen aufweisenden Armierungsbereich, vorzugsweise gelochten Armierungsbereich dar.The shell-shaped section 4.1 of the receiving body 4 and its flange 4.2 are elongated, with the shell-shaped section 4.1 and the flange 4.2 having two parallel longitudinal sections 4.21, which are connected to one another by two shorter, parallel transverse sections 4.22. The length of the shell-shaped section 4.1 measures, for example, approximately twice its width. The parallel longitudinal sections 4.21 of the flange are substantially perpendicular to the parallel transverse sections 4.22 of the flange. The flange 4.2 is provided with a plurality of recesses, preferably holes 4.4, which are used to anchor the receiving body 4 in a screed mass, with which the drain body 5 positioned on an unfinished floor is cast during a subsequent assembly step. The flange 4.2 thus represents a reinforcement area having recesses, preferably a perforated reinforcement area.

Zwischen dem schalenförmigen Abschnitt 4.1 und dem Flansch 4.2 ist ein nach oben vorstehender Steg 4.5 ausgebildet, der vorzugsweise als geschlossener Steg 4.5 ausgeführt ist. Vorzugsweise ist bis zum Abschluss der Estricharbeiten ein Bauschutzdeckel 7 in den schalenförmigen Abschnitt 4.1 eingesetzt. Der Bauschutzdeckel 7 ist so bemessen, dass er den schalenförmigen Abschnitt 4.1 vollständig abdeckt. Vorzugsweise deckt der Bauschutzdeckel 7 auch die Oberseite des Steges 4.5 im Wesentlichen vollständig ab. Der Bauschutzdeckel 7 ist mit dem Steg 4.5 bzw. dem Rand des schalenförmigen Abschnitts 4.1 lösbar und formschlüssig verbunden.Between the shell-shaped section 4.1 and the flange 4.2 there is an upwardly projecting web 4.5, which is preferably designed as a closed web 4.5. A protective cover 7 is preferably inserted into the shell-shaped section 4.1 until the screed work has been completed. The protective cover 7 is dimensioned so that it completely covers the shell-shaped section 4.1. The protective cover 7 preferably also covers the upper side of the web 4.5 essentially completely. The building protection cover 7 is detachably and positively connected to the web 4.5 or the edge of the shell-shaped section 4.1.

Der Flansch 4.2 weist an seiner Oberseite geradlinige Rillen 4.6 auf, die parallel zu den vier Seiten des Steges 4.5 bzw. Randes des schalenförmigen Abschnitts 4.1 verlaufen. Die Rillen 4.6 verlaufen vorzugsweise direkt entlang des Steges 4.5, wobei sich die Rillen 4.6 bis zur umlaufenden Kante 4.7 des Flansches 4.2 erstrecken. Die Rillen 4.6 dienen als Schneidrillen und ermöglichen ein einfaches Abtrennen eines Abschnitts des Flansches 4.2, insbesondere eines länglichen Flanschabschnitts 4.21 (vgl. Fig. 3). Nach Abtrennen eines länglichen Abschnitts 4.21 des Flansches kann der Steg 4.5 mit dem schalenförmigen Abschnitt 4.1 des in das Ablaufgehäuse 5 eingesteckten Aufnahmekörpers 4 bzw. der später montierte Wassersammelkörper (Rinnenkörper) 6 direkt an einer vertikalen Wand einer Duschzelle positioniert werden.The flange 4.2 has straight grooves 4.6 on its upper side, which run parallel to the four sides of the web 4.5 or the edge of the shell-shaped section 4.1. The grooves 4.6 preferably run directly along the web 4.5, with the grooves 4.6 extending as far as the peripheral edge 4.7 of the flange 4.2. The grooves 4.6 serve as cutting grooves and enable a section of the flange 4.2, in particular an elongated flange section 4.21 (cf. 3 ). After cutting off an elongated section 4.21 of the flange, the web 4.5 with the shell-shaped section 4.1 of the receiving body 4 inserted into the drain housing 5 or the water-collecting body (gutter body) 6 fitted later can be positioned directly on a vertical wall of a shower cubicle.

Soll der Wassersammelkörper (Rinnenkörper) 6 dagegen mittig oder dezentral, also mit deutlichem Abstand von der oder den vertikalen Wänden einer Duschzelle positioniert werden, so ist ein Abtrennen eines Abschnitts 4.21 des Flansches 4.2 nicht erforderlich. In diesem Fall ist der Flansch 4.2 mit dem schalenförmigen Abschnitt 4.1 des Aufnahmekörpers 4 nach dessen Montage am Ablaufgehäuse 5 noch um bis zu 360° drehbar. Der schalenförmige Abschnitt 4.1 des Aufnahmekörpers 4 und somit schließlich der längliche Wassersammelkörper (Rinnenkörper) 6 können in diesem Fall in einem Winkel im Bereich von 0 bis 90° zu einer angrenzenden Wand der Duschzelle variabel eingebaut werden.If, on the other hand, the water-collecting body (gutter body) 6 is to be positioned centrally or decentrally, ie at a clear distance from the vertical wall(s) of a shower cubicle, it is not necessary to separate a section 4.21 of the flange 4.2. In this case, the flange 4.2 with the shell-shaped section 4.1 of the receiving body 4 can still be rotated by up to 360° after it has been mounted on the drain housing 5. In this case, the shell-shaped section 4.1 of the receiving body 4 and thus finally the elongated water-collecting body (gutter body) 6 can be variably installed at an angle in the range from 0 to 90° to an adjacent wall of the shower cubicle.

Nach Abschluss der Positionierung des Ablaufgehäuses 5 mit dem darin eingesteckten Aufnahmekörpers 4 und nach Einstellung und Montage der Abwasserleitung (nicht gezeigt) an dem Ablaufstutzen 5.2 des Ablaufgehäuses 5 wird in den das Ablaufgehäuse 5 umgebenden Bereich Estrich E eingebracht, und zwar so, dass der Estrich E flächenbündig mit der Oberseite des Bauschutzdeckels 7 abschließt (Fig. 4). Vorzugsweise nach Aushärtung des Estrichs wird der Bauschutzdeckel entfernt (Fig. 5).After completing the positioning of the drain body 5 with the receiving body 4 inserted therein and after setting and installing the waste water pipe (not shown) on the drain socket 5.2 of the drain body 5, screed E is introduced into the area surrounding the drain body 5 in such a way that the screed E is flush with the top of the protective cover 7 ( 4 ). The protection cover is preferably removed after the screed has hardened ( figure 5 ).

Anschließend wird der schalenförmige Abschnitt 3.1 des ersten Aufnahmekörpers 3, an dessen Außenrand die flexible Dichtungsmatte 3.2 flüssigkeitsdicht angeschlossen ist und dessen Boden in den Ablaufstutzen 3.3 übergeht (vgl. Fig. 7), in den schalenförmigen Abschnitt 4.1 des zweiten, im Estrich E verankerten Aufnahmekörpers 4 eingesetzt (Fig. 5).Then the shell-shaped section 3.1 of the first receiving body 3, to the outer edge of which the flexible sealing mat 3.2 is connected in a liquid-tight manner and the bottom of which merges into the drain socket 3.3 (cf. 7 ), inserted into the shell-shaped section 4.1 of the second receiving body 4 anchored in the screed E ( figure 5 ).

Der kreisringförmige Ablaufstutzen 3.3 ist an seinem Außenumfang mit einer Ringdichtung (nicht gezeigt), vorzugsweise einem O-Ring versehen. Die Ringdichtung ist in einer am Außenumfang des Ablaufstutzens 3.3 ausgebildeten Ringnut 3.31 gehalten.The annular discharge nozzle 3.3 is provided with a ring seal (not shown), preferably an O-ring, on its outer circumference. The annular seal is held in an annular groove 3.31 formed on the outer circumference of the outlet connection 3.3.

Der schalenförmige Abschnitt 3.1 des oberen Aufnahmekörpers 3 und der schalenförmige Abschnitt 4.1 des unteren Aufnahmekörpers 4 sind mit einander zugeordneten Rastelementen 3.5 versehen, die beim Einsetzen des schalenförmigen Abschnitts 3.1 des oberen Aufnahmekörpers 3 in den schalenförmigen Abschnitt 4.1 des unteren Aufnahmekörpers 4 miteinander verrasten. In der Zeichnung ist lediglich eines der Rastelemente 3.5 zu sehen, und zwar ein Rastelement 3.5 des schalenförmigen Abschnitts 3.1 des oberen Aufnahmekörpers 3.The shell-shaped section 3.1 of the upper receiving body 3 and the shell-shaped section 4.1 of the lower receiving body 4 are provided with mutually associated latching elements 3.5, which snap together when inserting the shell-shaped section 3.1 of the upper receiving body 3 into the shell-shaped section 4.1 of the lower receiving body 4. Only one of the latching elements 3.5 can be seen in the drawing, namely a latching element 3.5 of the shell-shaped section 3.1 of the upper receiving body 3.

Die Rastelemente 3.5 des schalenförmigen Abschnitts 3.1 des oberen Aufnahmekörpers 3 sind beispielsweise in Form von Rastfedern (Clipsecken) ausgeführt. Durch die Rastverbindung der beiden schalenförmigen Abschnitte 3.1, 4.1 wird eine zuverlässige Abdichtung zwischen der Dichtungsmatte 3.2 des oberen Aufnahmekörpers 3 und dem Ablaufstutzen 4.3 des unteren Aufnahmekörpers 4 sicher vorgegeben.The latching elements 3.5 of the shell-shaped section 3.1 of the upper receiving body 3 are designed, for example, in the form of latching springs (clip corners). Through the locking connection of the two shell-shaped sections 3.1, 4.1, a reliable seal between the sealing mat 3.2 of the upper Recording body 3 and the drain pipe 4.3 of the lower receiving body 4 safely specified.

Vorzugsweise weisen die beiden schalenförmigen Abschnitte 3.1, 4.1 vier Paare einander zugeordneter Rastelemente 3.5 auf, die bei der Montage des schalenförmigen Abschnitts 3.1 des oberen Aufnahmekörpers 3 in dem schalenförmigen Abschnitt 4.1 des unteren Aufnahmekörpers 4 miteinander verrasten, wobei je ein Paar dieser Rastelemente 3.5 an einer der vier Seiten der schalenförmigen Abschnitte 3.1, 4.1 angeordnet ist.The two shell-shaped sections 3.1, 4.1 preferably have four pairs of mutually associated latching elements 3.5, which latch together when the shell-shaped section 3.1 of the upper receiving body 3 is installed in the shell-shaped section 4.1 of the lower receiving body 4, with one pair of these latching elements 3.5 being attached to one of the four sides of the shell-shaped sections 3.1, 4.1 is arranged.

Die schalenförmigen Abschnitte 3.1, 4.1 weisen jeweils einen umlaufenden Absatz 3.8, 4.8 auf, der einen mit Gefälle ausgebildeten Boden mit einer kreisförmigen Ablauföffnung 3.9, 4.9 umrahmt. Vorzugsweise ist die kreisförmige Ablauföffnung 3.9, 4.9 mittig angeordnet, wobei der Boden nach Art eines Trichters zwei an der Ablauföffnung endende Gefälleflächen 3.10, 4.10 aufweist (vgl. Fig. 8).The shell-shaped sections 3.1, 4.1 each have a circumferential shoulder 3.8, 4.8, which frames a bottom designed with a gradient and having a circular drainage opening 3.9, 4.9. The circular drainage opening 3.9, 4.9 is preferably arranged in the middle, with the base having two sloping surfaces 3.10, 4.10 ending at the drainage opening in the manner of a funnel (cf. 8 ).

In Fig. 8 ist ein Montagezustand des Bodenablaufs nach Anbringen der Dichtungsmatte 3.2 am Estrich gezeigt. Der Estrich wird außerhalb der flexiblen Dichtungsmatte 3.2 vorzugsweise mit zusätzlichem Dichtungsmaterial, beispielsweise mit flüssig auftragbarem und sich zu einer Folie verfestigendem Dichtungsmaterial (sogenannter Flüssigfolie) abgedichtet, in das die Dichtungsmatte 3.2 eingearbeitet wird. Auf diese Weise wird eine flexible Verbundabdichtung hergestellt. Die Dichtungsmatte 3.2 kann in ihren Randecken Löcher 3.21 aufweisen (Fig. 1), um eine formschlüssige Verbindung der Dichtungsmatte 3.2 mit einem auf dem Estrich oder einer Wand aufgebrachten Klebe- oder Dichtungsmaterial, insbesondere einer Flüssigfolie zu erzielen.In 8 an assembly state of the floor drain is shown after attaching the sealing mat 3.2 to the screed. Outside the flexible sealing mat 3.2, the screed is preferably sealed with additional sealing material, for example with sealing material that can be applied in liquid form and solidifies into a film (so-called liquid film), into which the sealing mat 3.2 is incorporated. In this way, a flexible bonded seal is created. The sealing mat 3.2 can have holes 3.21 in its edge corners ( 1 ) in order to achieve a positive connection of the sealing mat 3.2 with an adhesive or sealing material applied to the screed or a wall, in particular a liquid foil.

Der schalenförmige Abschnitt 3.1 des oberen Aufnahmekörpers 3 hat an seiner Ablauföffnung 3.9 einen umlaufenden Absatz, welcher als Halterung für einen in den Aufnahmekörper 3 einlegbaren Siebeinsatz 8 dient.The shell-shaped section 3.1 of the upper receiving body 3 has a peripheral shoulder at its outlet opening 3.9, which serves as a holder for a sieve insert 8 that can be inserted into the receiving body 3.

Nachdem die flexible Dichtungsmatte 3.2 mit zusätzlichem Dichtungsmaterial, vorzugsweise Flüssigfolie, als Verbundabdichtung am Estrich E und gegebenenfalls an der angrenzenden Wand der Duschzelle angebracht und getrocknet ist, wird der Einlaufkanalstutzen 2 in den schalenförmigen Abschnitt 3.1 des oberen Aufnahmekörpers 3 eingesetzt. Der Einlaufkanalstutzen 2 ist als Höhenausgleichsstück ausgeführt, um die Höhenposition des rinnenartigen Wassersammelkörpers 6 an die Höhe eines auf die Dichtungsmatte 3.2 aufzubringenden Bodenfliesen- oder Steinplattenbelages anpassen zu können. Der Einlaufkanalstutzen 2 ist hierzu aus gut schneidbarem Kunststoff, z. B. Polypropylen, hergestellt und weist eine Vielzahl umlaufender, zueinander paralleler Rillen (Schneidrillen) 2.2, vorzugsweise mit Lochperforation, auf, von denen jede als Führung für ein Messer zum Kürzen des Einlaufkanalstutzens 2 genutzt werden kann.After the flexible sealing mat 3.2 with additional sealing material, preferably liquid film, has been applied and dried as a bonded seal to the floor screed E and, if necessary, to the adjoining wall of the shower cubicle, the inlet duct socket 2 is inserted into the shell-shaped section 3.1 of the upper receiving body 3. The inlet channel socket 2 is designed as a height adjustment piece in order to be able to adjust the height position of the channel-like water collection body 6 to the height of a floor tile or stone slab covering to be applied to the sealing mat 3.2. For this purpose, the inlet duct socket 2 is made of easily cuttable plastic, e.g. B. polypropylene, and has a plurality of circumferential, mutually parallel grooves (cutting grooves) 2.2, preferably with hole perforation, each of which can be used as a guide for a knife to shorten the inlet channel socket 2.

Ferner ist in Fig. 9 zu erkennen, dass der schalenförmige Abschnitt 3.1 des Aufnahmekörpers 3 größer bemessen ist als der Einlaufkanalstutzen 2, so dass der Einlaufkanalstutzen 2 in zwei quer zueinander verlaufenden Richtungen horizontal verschiebbar in dem schalenförmigen Abschnitt 3.1 des oberen Aufnahmekörpers 3 aufgenommen ist. Somit lassen sich insbesondere der Abstand des rinnenartigen Wassersammelkörpers 6 von einer benachbarten Wand und/oder die Lage der Einlauföffnung 6.21 relativ zu einer Bodenbelagsfuge justieren. Der in seiner Höhe kürzbare Einlaufkanalstutzen 2 liegt dabei mit seiner Unterkante auf dem umlaufenden Absatz 3.8 des schalenförmigen Abschnitts 3.1 auf.Furthermore, in 9 It can be seen that the shell-shaped section 3.1 of the receiving body 3 is dimensioned larger than the inlet channel socket 2, so that the inlet channel socket 2 is received in the shell-shaped section 3.1 of the upper receiving body 3 so that it can be displaced horizontally in two directions running transversely to one another. Thus, in particular, the distance between the channel-like water collection body 6 and an adjacent wall and/or the position of the inlet opening 6.21 can be adjusted relative to a floor covering joint. The height of the inlet duct socket 2, which can be shortened, rests with its lower edge on the circumferential shoulder 3.8 of the shell-shaped section 3.1.

Zudem ist der rinnenartigen Wassersammelkörpers 6, der vorzugsweise aus Edelstahl hergestellt und verformungsresistent ausgeführt ist, mittels einer Metallsäge oder eines anderen Metallschneidwerkzeuges kürzbar, so dass die Länge des Wassersammelkörpers 6 bei Bedarf an das Bodenfliesenformat oder die Größe einer benachbarten Bodenbelagsplatte angepasst werden kann.In addition, the channel-like water-collecting body 6, which is preferably made of stainless steel and designed to be resistant to deformation, can be shortened using a hacksaw or another metal-cutting tool, so that the length of the water-collecting body 6 can be adjusted to the floor tile format or the size of an adjacent floor covering panel if necessary.
