Definitions

  • the invention relates to a drainage channel for sanitary areas and/or for terrace areas with the features of the preamble of claim 1 as well as its manufacture and installation.
  • the invention further relates to a method for producing and a method for installing such a drainage channel.
  • Known drainage channels for showers usually have a channel element with at least one drain.
  • the drain serves for primary drainage.
  • Primary drainage refers to the drainage of dirty water that occurs, for example, when showering.
  • the well-known drainage channel also has a frame with a frame flange, which is connected to floor tiles during installation.
  • the gutter element and the frame are separate components that are inserted into one another when the drainage gutter is installed.
  • the gutter element is dimensioned such that a circumferential gap is created between the gutter element and the frame, which is fluidly connected to the drain of the gutter element. This gap is arranged in such a way that a second drainage level is formed for secondary drainage.
  • Secondary drainage is known in connection with open-pored floor coverings, for example in parking garages or on terraces, through which water can drain away. This term is also used in connection with drainage channels for sanitary areas, whereby, in contrast to open-pored floor coverings, there is no flow of water under the tiles, but rather a diffusion of water. For example, if water penetrates the floor through damaged tile joints or floor coverings made of natural stone, the floor covering can become saturated with water or water or moisture can accumulate under the floor. Secondary drainage enables damp floor coverings or floor tiles to dry out.
  • a drainage channel with a connection area and a drain profile is known.
  • the connection area When installed, the connection area is located under floor tiles, with the drainage profile having several elevations between which passages are provided for secondary drainage.
  • the passages are formed between the connection area and the drain profile.
  • the shower drain includes flanges with multiple openings that allow leakage water to drain into the gutter.
  • Another process is from the EP 2 278 081 A2 known, which has a collecting basin and a connection frame.
  • the connection frame is arranged adjacent to the collecting basin and has passage openings for removing moisture.
  • the passage openings serve for secondary drainage.
  • a gutter cover As shown in the DE 20 2005 001 437 U1 disclosed, are used.
  • the gutter cover prevents objects from entering the gutter, for example.
  • the DE8910414U which represents the closest state of the art, describes a drainage channel with a secondary drainage.
  • the invention is based on the object of improving the drainage channel of the type mentioned in such a way that the drainage channel, on the one hand, enables secondary drainage and, on the other hand, is relatively easy and quick to clean.
  • the invention is also based on the object of specifying a method for producing such a gutter and a method for installing such a gutter.
  • a drainage channel with the features of claim 1.
  • the task is solved by a drainage channel for sanitary areas, in particular for showers, and/or for terrace areas with a channel element that has at least one outlet for primary drainage.
  • the drainage channel includes a frame having a frame flange for connection to tiles and a device for secondary drainage.
  • the gutter element and the frame are firmly connected.
  • the device for secondary drainage is integrated into the gutter element or integrated into the gutter element and the frame.
  • the invention has the advantage that the drainage channel can be designed to be easy to clean, so that the channel element can be cleaned with a simple cleaning cloth.
  • the gutter element and the frame are firmly connected on the one hand and, on the other hand, the device for secondary drainage forms an integral part of the gutter element or the gutter element and the frame.
  • the device for secondary drainage can be integrated either only in the gutter element or in the gutter element and in the frame.
  • the device for secondary drainage is not formed by the formation of a circumferential gap between the channel element and the frame flange and the required interaction of these components. Rather, the device for secondary drainage is integrated into the gutter element as such or into the gutter element and the frame as such. This decouples these components with regard to the secondary drainage, so that the channel element can be optimized in terms of ease of cleaning.
  • the integrated secondary drainage allows the floor to dry quickly, even with natural stone coverings.
  • the solid connection between the channel element and the frame also has the further advantage that the drainage channel can be installed quickly and safely.
  • the drainage channel can be completely pre-assembled.
  • a fixed connection between the gutter element and the frame is understood to be a connection that cannot be released without being destroyed.
  • the drainage channel can be understood as a one-piece installation element that can be handled uniformly as a whole.
  • Secondary drainage means that water that can penetrate under the floor covering or under the floor tiles, for example due to damaged joints, can diffuse into the drainage channel, in particular the channel element.
  • Primary drainage means the drainage of dirty water that occurs, for example, when showering or generally when draining a bathroom. Preferred embodiments of the invention are specified in the subclaims.
  • the first diffusion openings each form an elongated opening through the gutter flange, which is delimited at the bottom by the top of the frame flange.
  • the respective channel forms an elongated slot which extends essentially perpendicular to the longitudinal direction of the channel element in the area of the longer side.
  • the gutter element has a gutter flange which is firmly connected to the frame flange of the frame.
  • the gutter flange and the frame flange can be placed plane-parallel to one another and firmly connected to one another. This creates a secure and tight connection between the gutter element and the frame.
  • the gutter flange and the frame flange preferably form flat surfaces that extend essentially vertically outwards from the gutter element. When installed, the gutter flange and the frame flange are at least partially arranged essentially horizontally. The frame flange can be folded up on the wall side.
  • the gutter flange is arranged in a recess on the top of the frame flange. This has the advantage that the gutter flange can be completely recessed into the frame flange, so that the frame flange forms a continuous flat surface that can be connected to floor tiles or other floor coverings.
  • the gutter element and the frame are firmly connected by point connections. It has been shown that in connection with the full-surface support of the two components, point connections are sufficient for sufficient strength.
  • the point connections include clinching joint connections.
  • clinching connections In contrast to rivet connections, clinching connections have the advantage that the material to be connected is only reshaped and the seal is therefore maintained. Also offer Reinforcing joint connections have good strength values that are sufficient for the use of drainage channels in sanitary areas.
  • Reinforced joint connections are understood to mean connections that connect flat metallic components, in particular sheets, without the use of an additional material.
  • Drainage channel preferably made of metal, more preferably made of steel, especially stainless steel.
  • the joining connection is made by reshaping the components to be connected, whereby a positive and non-positive connection is achieved.
  • Throughput joining is also known as pressure joining, clinching, press joining or toxing.
  • the device for secondary drainage can preferably have a profiling on the underside of the frame, in particular on the underside of the frame flange.
  • the underside of the frame or the frame flange can have an outwardly projecting profile in the form of local spacers. When installed, the spacers stand on the surface on which the drainage channel is arranged. As a result, a cavity is formed between the substrate and the underside of the frame or the frame flange, through which moisture or water that has penetrated under the floor tiles or under the floor covering can diffuse.
  • the device for secondary drainage is integrated into the frame or into the frame flange.
  • the profiling is formed by deformed sections of the frame, in particular the frame flange in the area of the clinching joints.
  • the clinching joints lead to bulges on the underside of the frame, especially the frame flange, which act as spacers.
  • the clinching joints therefore have a dual function. On the one hand, these enable a firm connection between the gutter element and the frame. On the other hand, the clinching joint connections on the underside of the frame or the frame flange form the profiling responsible for secondary drainage in the form of local bulges that arise during forming.
  • the device for secondary drainage has diffusion openings which are formed in the channel element.
  • the Diffusion openings and thus the device for secondary drainage form an integral part of the channel element.
  • the diffusion openings have the advantage that water that has penetrated under the floor tiles or floor coverings can diffuse out and get outside through the diffusion openings. This promotes the drying of the soil. It has been shown that several discrete diffusion openings are sufficient to achieve sufficient drying. It is not absolutely necessary that a continuous gap is formed that runs around the entire channel element. The larger the number of diffusion openings, the better the drying effect or secondary drainage. The number of diffusion openings depends on the length of the drainage channel. In a typical drainage channel for a shower, 4 to 10 diffusion openings per channel side are sufficient. A different number of drainage openings is possible.
  • first diffusion openings are formed in the gutter flange and second diffusion openings are formed in a side wall of the gutter element.
  • the first diffusion openings in the gutter flange each merge into associated second diffusion openings in the side wall of the gutter element and form channels that open into the gutter element. This creates a good fluid connection between the underside of the floor tiles or floor covering and the gutter element, so that the moisture contained in the floor tiles or floor covering can dry off easily.
  • a sealing sleeve is preferably connected to the frame flange.
  • the sealing sleeve is flexible to different degrees in different directions. This has the advantage that the sealing sleeve can be flexibly adjusted in the direction in which the greatest gutter work occurs in order to minimize joint cracks. It is therefore particularly preferred if the sealing sleeve is more flexible in a direction transverse to the longitudinal axis of the gutter element than in a direction parallel to the longitudinal axis of the gutter element.
  • the surface of the channel element is electropolished. This ensures a long gloss retention and low dirt build-up on the channel element.
  • a drain pot is preferably welded to the gutter element. This enables a fully-fledged steel gutter, especially stainless steel gutter, which can be installed quickly and safely and meets the highest demands in terms of design and care.
  • the fully welded drain pot or drain permanently protects the floor structure from water penetration.
  • the object is achieved by a method for producing a drainage channel according to the invention, in which diffusion openings for secondary drainage are introduced into a channel element which has at least one outlet for primary drainage.
  • the gutter element is firmly connected to a frame by clinching.
  • the task is solved by a method for installing a drainage channel according to the invention, in which a liquid seal is either applied at a distance in front of the device for secondary drainage in such a way that the device for secondary drainage is open in the installed state.
  • the liquid waterproofing is applied in such a way that the secondary drainage device is covered and closed. This primarily concerns the diffusion openings, which can be activated or deactivated in this way depending on whether secondary drainage is desired or not.
  • the drainage channel shown in the figures is used for drainage in sanitary areas and/or terrace areas.
  • the drainage channel is installed in tiled floors or in floors with natural stone coverings, where secondary drainage can be important in addition to primary drainage.
  • the drainage channel is primarily designed for showers and can be called a shower channel. Other possible applications in the sanitary sector are conceivable.
  • the drainage channel has a channel element 10 with a substantially rectangular shape.
  • a drain 11 is formed in the bottom of the channel element 10.
  • the floor is inclined in a manner known per se, so that the drain 11 is arranged at the lowest point of the channel element. It is possible to provide more than one drain 11, especially for longer drainage channels.
  • the gutter element 10 has side walls 19 which extend substantially perpendicular to the bottom of the gutter element 10 and, as shown in FIGS Figures 1, 2 easy to see, forming a supernatant.
  • the overhang essentially corresponds to the connection height of the floor tiles or floor covering.
  • the Side walls 19 are each connected to a gutter flange 15, in particular connected in one piece, which extends outwards perpendicular to the side walls 19.
  • the gutter element 10 is arranged in or on a frame 12, which has a frame flange 13, and is firmly connected to it.
  • the frame flange 13 extends perpendicular to the side walls 19 of the gutter element 10. When installed, the frame flange 13 and the gutter flange 15 are arranged horizontally.
  • the gutter element 10 has a device for secondary drainage 14.
  • the device for secondary drainage 14 serves to enable the diffusion of moisture or water that has accumulated below or in the floor tiles or in the floor covering, for example due to damaged tile joints.
  • the device for secondary drainage 14 is designed in the form of diffusion openings 17, 18.
  • the diffusion openings 17, 18 are located in the gutter element 10, specifically in the gutter flange 15 and in the side walls 19 of the gutter element 10.

Description

Die Erfindung betrifft eine Entwässerungsrinne für Sanitärbereiche und/oder für Terrassenbereiche mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie ihre Herstellung und ihren Einbau.The invention relates to a drainage channel for sanitary areas and/or for terrace areas with the features of the preamble of claim 1 as well as its manufacture and installation.

Derartige Entwässerungsrinnen sind aus der Praxis bekannt und auf dem Markt erhältlich. Die Erfindung betrifft ferner ein Verfahren zur Herstellung und ein Verfahren zum Einbau derartiger Entwässerungsrinne.Such drainage channels are known from practice and are available on the market. The invention further relates to a method for producing and a method for installing such a drainage channel.

Bekannte Entwässerungsrinnen für Duschen weisen üblicherweise ein Rinnenelement mit wenigstens einem Ablauf auf. Der Ablauf dient dabei der Primärentwässerung. Unter Primärentwässerung wird der Ablauf des Schmutzwassers verstanden, der beispielsweise beim Duschen anfällt. Die bekannte Entwässerungsrinne weist ferner einen Rahmen mit einem Rahmenflansch auf, der beim Einbau mit Bodenfliesen verbunden wird. Das Rinnenelement und der Rahmen sind gesonderte Bauteile, die beim Einbau der Entwässerungsrinne ineinander gesteckt werden. Dabei ist das Rinnenelement so dimensioniert, dass zwischen dem Rinnenelement und dem Rahmen ein umlaufender Spalt entsteht, der mit dem Ablauf des Rinnenelements fluidverbunden ist. Dieser Spalt ist so angeordnet, dass eine zweite Entwässerungsebene für die Sekundärentwässerung gebildet wird.Known drainage channels for showers usually have a channel element with at least one drain. The drain serves for primary drainage. Primary drainage refers to the drainage of dirty water that occurs, for example, when showering. The well-known drainage channel also has a frame with a frame flange, which is connected to floor tiles during installation. The gutter element and the frame are separate components that are inserted into one another when the drainage gutter is installed. The gutter element is dimensioned such that a circumferential gap is created between the gutter element and the frame, which is fluidly connected to the drain of the gutter element. This gap is arranged in such a way that a second drainage level is formed for secondary drainage.

Die Sekundärentwässerung ist im Zusammenhang mit offenporigen Bodenbelägen zum Beispiel in Parkhäusern oder auf Terrassen bekannt, durch die Wasser abfließen kann. Im Zusammenhang mit Entwässerungsrinnen für Sanitärbereiche wird dieser Begriff ebenfalls verwendet, wobei es im Unterschied zu offenporigen Bodenbelägen nicht zu einem Wasserstrom unter den Fliesen, sondern eher zu einer Diffusion von Wasser kommt. Dringt beispielsweise durch beschädigte Fliesenfugen oder Bodenbeläge aus Naturstein Wasser in den Boden ein, kann der Bodenbelag sich mit Wasser vollsaugen bzw. sich Wasser bzw. Feuchtigkeit unter dem Boden ansammeln. Die Sekundärentwässerung ermöglicht das Abtrocknen feuchter Bodenbeläge bzw. Bodenfliesen.Secondary drainage is known in connection with open-pored floor coverings, for example in parking garages or on terraces, through which water can drain away. This term is also used in connection with drainage channels for sanitary areas, whereby, in contrast to open-pored floor coverings, there is no flow of water under the tiles, but rather a diffusion of water. For example, if water penetrates the floor through damaged tile joints or floor coverings made of natural stone, the floor covering can become saturated with water or water or moisture can accumulate under the floor. Secondary drainage enables damp floor coverings or floor tiles to dry out.

Aus der DE 10 2011 050 825 A1 ist bspw. eine Entwässerungsrinne mit einem Anschlussbereich und einem Drainprofil bekannt. Im eingebauten Zustand befindet sich der Anschlussbereich unter Bodenfliesen, wobei das Drainprofil mehrere Erhebungen aufweist, zwischen denen Durchlässe zur Sekundärentwässerung vorgesehen sind. Die Durchlässe sind zwischen dem Anschlussbereich und dem Drainprofil ausgebildet.From the DE 10 2011 050 825 A1 For example, a drainage channel with a connection area and a drain profile is known. When installed, the connection area is located under floor tiles, with the drainage profile having several elevations between which passages are provided for secondary drainage. The passages are formed between the connection area and the drain profile.

Ferner offenbart die EP 2 472 015 A1 einen Duschablauf mit einer Rinne. Der Duschablauf umfasst Flansche mit mehreren Öffnungen, durch die Leckwasser in die Rinne ablaufen kann.Furthermore, the reveals EP 2 472 015 A1 a shower drain with a channel. The shower drain includes flanges with multiple openings that allow leakage water to drain into the gutter.

Ein weiterer Ablauf ist aus der EP 2 278 081 A2 bekannt, der ein Sammelbecken und einen Anschlussrahmen aufweist. Der Anschlussrahmen ist am Sammelbecken anliegend angeordnet und weist Durchlassöffnungen zum Abführen von Feuchtigkeit auf. Die Durchlassöffnungen dienen dabei zur Sekundärentwässerung.Another process is from the EP 2 278 081 A2 known, which has a collecting basin and a connection frame. The connection frame is arranged adjacent to the collecting basin and has passage openings for removing moisture. The passage openings serve for secondary drainage.

Zur Abdeckung einer Rinne kann eine Rinnenabdeckung, wie in der DE 20 2005 001 437 U1 offenbart, zum Einsatz kommen. Durch die Rinnenabdeckung wird bspw. das Eindringen von Gegenständen in die Rinne verhindert.To cover a gutter, you can use a gutter cover, as shown in the DE 20 2005 001 437 U1 disclosed, are used. The gutter cover prevents objects from entering the gutter, for example.

Die DE8910414U , die den nächstkommenden Stand der Technik darstellt, beschreibt eine Entwässerungsrinne mit einer Senkundärentwässerung.The DE8910414U , which represents the closest state of the art, describes a drainage channel with a secondary drainage.

Bekannte Entwässerungsrinnen mit Sekundärentwässerung lassen sich nur schwer reinigen. Stege, Schmutzfugen und Einbauten (z.B. zur Höhenverstellung der Roste) verhindern eine leichte Pflege. Gerade die umlaufenden Hohlräume zwischen Rahmen und Rinne können nicht ohne weiteres gereinigt werden, weil diese nicht zugänglich sind. Deshalb sind häufig Reinigungsutensilien (z.B. kleine Bürsten) im Lieferumfang enthalten. Die Reinigung ist jedoch umständlich und aufwendig.Known drainage channels with secondary drainage are difficult to clean. Bars, dirt joints and fixtures (e.g. for height adjustment of the grates) prevent easy maintenance. The surrounding cavities between the frame and the gutter in particular cannot be cleaned easily because these are not accessible. That's why cleaning utensils (e.g. small brushes) are often included in the scope of delivery. However, cleaning is complicated and time-consuming.

Die Erfindung liegt die Aufgabe zu Grunde, die Entwässerungsrinne der eingangs genannten Art dahingehend zu verbessern, dass die Entwässerungsrinne einerseits die Sekundärentwässerung ermöglicht und andererseits relativ einfach und schnell zu reinigen ist. Der Erfindung liegt ferner die Aufgabe zu Grunde, ein Verfahren zur Herstellung einer derartigen Rinne und ein Verfahren zum Einbau einer solchen Rinne anzugeben.The invention is based on the object of improving the drainage channel of the type mentioned in such a way that the drainage channel, on the one hand, enables secondary drainage and, on the other hand, is relatively easy and quick to clean. The invention is also based on the object of specifying a method for producing such a gutter and a method for installing such a gutter.

Erfindungsgemäß wird diese Aufgabe durch eine Entwässerungsrinne mit den Merkmalen des Anspruchs 1 gelöst. Konkret wird die Aufgabe durch eine Entwässerungsrinne für Sanitärbereiche, insbesondere für Duschen, und/oder für Terrassenbereiche mit einem Rinnenelement gelöst, dass wenigstens einen Ablauf für eine Primärentwässerung aufweist. Die Entwässerungsrinne umfasst einen Rahmen, der einen Rahmenflansch zur Verbindung mit Fliesen aufweist, und eine Einrichtung für eine Sekundärentwässerung. Das Rinnenelement und der Rahmen sind fest verbunden. Die Einrichtung für die Sekundärentwässerung ist in das Rinnenelement integriert oder in das Rinnenelement und in den Rahmen integriert.According to the invention, this object is achieved by a drainage channel with the features of claim 1. Specifically, the task is solved by a drainage channel for sanitary areas, in particular for showers, and/or for terrace areas with a channel element that has at least one outlet for primary drainage. The drainage channel includes a frame having a frame flange for connection to tiles and a device for secondary drainage. The gutter element and the frame are firmly connected. The device for secondary drainage is integrated into the gutter element or integrated into the gutter element and the frame.

Die Erfindung hat den Vorteil, dass die Entwässerungsrinne reinigungsfreundlich konzipiert werden kann, sodass das Rinnenelement mit einem einfachen Reinigungstuch gereinigt werden kann. Dazu ist vorgesehen, dass das Rinnenelement und der Rahmen einerseits fest verbunden und andererseits die Einrichtung für die Sekundärentwässerung einen integralen Bestandteil des Rinnenelements oder des Rinnenelements und des Rahmens bildet. Dabei kann die Einrichtung für die Sekundärentwässerung entweder nur in das Rinnenelement oder jeweils in das Rinnenelement und in den Rahmen integriert sein.The invention has the advantage that the drainage channel can be designed to be easy to clean, so that the channel element can be cleaned with a simple cleaning cloth. For this purpose, it is provided that the gutter element and the frame are firmly connected on the one hand and, on the other hand, the device for secondary drainage forms an integral part of the gutter element or the gutter element and the frame. The device for secondary drainage can be integrated either only in the gutter element or in the gutter element and in the frame.

Im Unterschied zum Stand der Technik wird also die Einrichtung für die Sekundärentwässerung nicht durch die Bildung eines umlaufenden Spaltes zwischen dem Rinnenelement und dem Rahmenflansch und das dafür erforderliche Zusammenwirken dieser Bauteile gebildet. Die Einrichtung für die Sekundärentwässerung ist vielmehr in das Rinnenelement als solches oder in das Rinnenelement und in den Rahmen als solches integriert. Dadurch werden diese Bauteile mit Bezug auf die Sekundärentwässerung entkoppelt, sodass das Rinnenelement mit Blick auf die Reinigungsfreundlichkeit optimiert werden kann. Die integrierte Sekundärentwässerung erlaubt selbst bei Natursteinbelägen die rasche Abtrocknung des Bodens.In contrast to the prior art, the device for secondary drainage is not formed by the formation of a circumferential gap between the channel element and the frame flange and the required interaction of these components. Rather, the device for secondary drainage is integrated into the gutter element as such or into the gutter element and the frame as such. This decouples these components with regard to the secondary drainage, so that the channel element can be optimized in terms of ease of cleaning. The integrated secondary drainage allows the floor to dry quickly, even with natural stone coverings.

Die feste Verbindung zwischen dem Rinnenelement und dem Rahmen hat darüber hinaus den weiteren Vorteil, dass die Entwässerungsrinne schnell und sicher eingebaut werden kann. Die Entwässerungsrinne kann komplett vormontiert werden.The solid connection between the channel element and the frame also has the further advantage that the drainage channel can be installed quickly and safely. The drainage channel can be completely pre-assembled.

Unter einer festen Verbindung zwischen dem Rinnenelement und dem Rahmen wird eine Verbindung verstanden, die nicht zerstörungsfrei gelöst werden kann. Die Entwässerungsrinne kann als ein einteiliges Einbauelement verstanden werden, das als Ganzes einheitlich handhabbar ist.A fixed connection between the gutter element and the frame is understood to be a connection that cannot be released without being destroyed. The drainage channel can be understood as a one-piece installation element that can be handled uniformly as a whole.

Sekundärentwässerung bedeutet, dass Wasser, das unter dem Bodenbelag bzw. unter die Bodenfliesen, beispielsweise aufgrund beschädigter Fugen eindringen kann, in die Entwässerungsrinne, insbesondere das Rinnenelement diffundieren kann. Primärentwässerung bedeutet die Entwässerung des beispielsweise beim Duschen bzw. generell bei der Badentwässerung anfallenden Schmutzwassers. Bevorzugte Ausführungen der Erfindung sind in den Unteransprüchen angegeben.Secondary drainage means that water that can penetrate under the floor covering or under the floor tiles, for example due to damaged joints, can diffuse into the drainage channel, in particular the channel element. Primary drainage means the drainage of dirty water that occurs, for example, when showering or generally when draining a bathroom. Preferred embodiments of the invention are specified in the subclaims.

Erfindungsgemäß bilden die ersten Diffusionsöffnungen jeweils einen länglichen Durchbruch durch den Rinnenflansch, der unten durch die Oberseite des Rahmenflansches begrenzt ist. Dabei bildet der jeweilige Kanal einen länglichen Schlitz, der sich im Wesentlichen senkrecht zur Längsrichtung des Rinnenelements im Bereich der längeren Seite erstreckt.According to the invention, the first diffusion openings each form an elongated opening through the gutter flange, which is delimited at the bottom by the top of the frame flange. The respective channel forms an elongated slot which extends essentially perpendicular to the longitudinal direction of the channel element in the area of the longer side.

Erfindungsgemäß weist das Rinnenelement einen Rinnenflansch auf, der mit dem Rahmenflansch des Rahmens fest verbunden ist. Der Rinnenflansch und der Rahmenflansch können bei der Herstellung der Entwässerungsrinne planparallel aufeinander gelegt und fest miteinander verbunden werden. Dadurch wird eine sichere und dichte Verbindung zwischen dem Rinnenelement und dem Rahmen geschaffen.According to the invention, the gutter element has a gutter flange which is firmly connected to the frame flange of the frame. When producing the drainage channel, the gutter flange and the frame flange can be placed plane-parallel to one another and firmly connected to one another. This creates a secure and tight connection between the gutter element and the frame.

Der Rinnenflansch und der Rahmenflansch bilden vorzugsweise ebene Flächen, die sich im Wesentlichen senkrecht vom Rinnenelement nach außen erstrecken. Im Einbauzustand sind der Rinnenflansch und der Rahmenflansch zumindest teilweise im Wesentlichen horizontal angeordnet. Der Rahmenflansch kann wandseitig aufgekantet sein.The gutter flange and the frame flange preferably form flat surfaces that extend essentially vertically outwards from the gutter element. When installed, the gutter flange and the frame flange are at least partially arranged essentially horizontally. The frame flange can be folded up on the wall side.

Der Rinnenflansch ist bei einer bevorzugten Ausführung in einer Ausnehmung auf der Oberseite des Rahmenflansches angeordnet. Dies hat den Vorteil, dass der Rinnenflansch im Rahmenflansch vollständig versenkt werden kann, sodass der Rahmenflansch eine durchgängig flache Oberfläche bildet, die mit Bodenfliesen oder anderen Bodenbelägen verbunden werden kann.In a preferred embodiment, the gutter flange is arranged in a recess on the top of the frame flange. This has the advantage that the gutter flange can be completely recessed into the frame flange, so that the frame flange forms a continuous flat surface that can be connected to floor tiles or other floor coverings.

Vorzugsweise sind das Rinnenelement und der Rahmen, insbesondere der Rinnenflansch und der Rahmenflansch, durch Punktverbindungen fest verbunden. Es hat sich gezeigt, dass im Zusammenhang mit der vollflächigen Auflage der beiden Bauteilen Punktverbindungen für eine ausreichende Festigkeit ausreichen.Preferably, the gutter element and the frame, in particular the gutter flange and the frame flange, are firmly connected by point connections. It has been shown that in connection with the full-surface support of the two components, point connections are sufficient for sufficient strength.

Bei einer besonders bevorzugten Ausführung umfassen die Punktverbindungen Durchsetzfügeverbindungen. Im Unterschied zu Nietverbindungen haben Durchsetzfügeverbindungen den Vorteil, dass das zu verbindende Material nur umgeformt und somit die Dichtigkeit beibehalten wird. Außerdem bieten Durchsetzfügeverbindungen gute Festigkeitswerte, die für die Anwendung der Entwässerungsrinne im Sanitärbereich ausreichen.In a particularly preferred embodiment, the point connections include clinching joint connections. In contrast to rivet connections, clinching connections have the advantage that the material to be connected is only reshaped and the seal is therefore maintained. Also offer Reinforcing joint connections have good strength values that are sufficient for the use of drainage channels in sanitary areas.

Unter Durchsetzfügeverbindungen werden Verbindungen verstanden, die flache metallische Bauteile, insbesondere Bleche ohne Verwendung eines Zusatzwerkstoffes verbinden. Konkret ist die erfindungsgemäße Entwässerungsrinne vorzugsweise aus Metall, weiter vorzugsweise aus Stahl, insbesondere Edelstahl hergestellt. Die Fügeverbindung erfolgt durch Umformen der zu verbindenden Bauteile, wodurch eine form-und kraftschlüssige Verbindung erreicht wird. Das Durchsatzfügen ist auch unter den Begriffen Druckfügen, Clinchen, Press Joining oder Toxen bekannt.Reinforced joint connections are understood to mean connections that connect flat metallic components, in particular sheets, without the use of an additional material. Specifically, the one according to the invention Drainage channel preferably made of metal, more preferably made of steel, especially stainless steel. The joining connection is made by reshaping the components to be connected, whereby a positive and non-positive connection is achieved. Throughput joining is also known as pressure joining, clinching, press joining or toxing.

Die Einrichtung für die Sekundärentwässerung kann vorzugsweise eine Profilierung an der Unterseite des Rahmens, insbesondere an der Unterseite des Rahmenflansches aufweisen. Dabei kann beispielsweise die Unterseite des Rahmens bzw. des Rahmenflansches ein nach außen vorstehendes Profil in der Form lokaler Abstandshalter aufweisen. Die Abstandshalter stehen im eingebauten Zustand auf dem Untergrund auf, auf dem die Entwässerungsrinne angeordnet ist. Dadurch wird zwischen dem Untergrund und der Unterseite des Rahmens bzw. des Rahmenflansches ein Hohlraum gebildet, durch den Feuchtigkeit bzw. Wasser diffundieren kann, das unter die Bodenfliesen bzw. unter den Bodenbelag eingedrungen ist.The device for secondary drainage can preferably have a profiling on the underside of the frame, in particular on the underside of the frame flange. For example, the underside of the frame or the frame flange can have an outwardly projecting profile in the form of local spacers. When installed, the spacers stand on the surface on which the drainage channel is arranged. As a result, a cavity is formed between the substrate and the underside of the frame or the frame flange, through which moisture or water that has penetrated under the floor tiles or under the floor covering can diffuse.

Bei dieser Ausführungsform ist die Einrichtung für die Sekundärentwässerung in den Rahmen bzw. in den Rahmenflansch integriert.In this embodiment, the device for secondary drainage is integrated into the frame or into the frame flange.

Bei einer besonders bevorzugten Ausführung ist die Profilierung durch umgeformte Abschnitte des Rahmens, insbesondere des Rahmenflansches im Bereich der Durchsetzfügeverbindungen gebildet. Die Durchsetzfügeverbindungen führen zu Auswölbungen auf der Unterseite des Rahmens, insbesondere des Rahmenflansches, die als Abstandshalter fungieren.In a particularly preferred embodiment, the profiling is formed by deformed sections of the frame, in particular the frame flange in the area of the clinching joints. The clinching joints lead to bulges on the underside of the frame, especially the frame flange, which act as spacers.

Die Durchsetzfügeverbindungen haben demnach eine Doppelfunktion. Einerseits ermöglichen diese die feste Verbindung zwischen dem Rinnenelement und dem Rahmen. Andererseits bilden die Durchsetzfügeverbindungen an der Unterseite des Rahmens bzw. des Rahmenflansches die für die Sekundärentwässerung verantwortlichen Profilierung in der Form von lokalen Auswölbung, die beim Umformen entstehen.The clinching joints therefore have a dual function. On the one hand, these enable a firm connection between the gutter element and the frame. On the other hand, the clinching joint connections on the underside of the frame or the frame flange form the profiling responsible for secondary drainage in the form of local bulges that arise during forming.

Erfindungsgemäß weist die Einrichtung für die Sekundärentwässerung Diffusionsöffnungen auf, die im Rinnenelement ausgebildet sind. Die Diffusionsöffnungen und damit die Einrichtung für die Sekundärentwässerung bilden einen integralen Bestandteil des Rinnenelements.According to the invention, the device for secondary drainage has diffusion openings which are formed in the channel element. The Diffusion openings and thus the device for secondary drainage form an integral part of the channel element.

Die Diffusionsöffnungen haben den Vorteil, dass Wasser, das unter die Bodenfliesen bzw. Bodenbeläge eingedrungen ist, heraus diffundieren und durch die Diffusionsöffnungen ins Freie gelangen kann. Dadurch wird das Abtrocknen des Bodens gefördert. Es hat sich gezeigt, dass mehrere diskrete Diffusionsöffnungen genügen, um eine ausreichende Abtrocknung zu erreichen. Es ist nicht zwingend erforderlich, dass ein durchgängiger Spalt gebildet wird, der um das gesamte Rinnenelement umläuft. Je größer die Anzahl der Diffusionsöffnungen ist, umso besser ist die Trocknungswirkung bzw. die Sekundärentwässerung. Die Anzahl der Diffusionsöffnungen hängt von der Länge der Entwässerungsrinne ab. Bei einer typischen Entwässerungsrinne für eine Dusche genügen von 4 bis 10 Diffusionsöffnungen pro Rinnenseite. Eine andere Anzahl von Entwässerungsöffnungen ist möglich.The diffusion openings have the advantage that water that has penetrated under the floor tiles or floor coverings can diffuse out and get outside through the diffusion openings. This promotes the drying of the soil. It has been shown that several discrete diffusion openings are sufficient to achieve sufficient drying. It is not absolutely necessary that a continuous gap is formed that runs around the entire channel element. The larger the number of diffusion openings, the better the drying effect or secondary drainage. The number of diffusion openings depends on the length of the drainage channel. In a typical drainage channel for a shower, 4 to 10 diffusion openings per channel side are sufficient. A different number of drainage openings is possible.

Erfindungsgemäß sind erste Diffusionsöffnungen im Rinnenflansch und zweite Diffusionsöffnungen in einer Seitenwand des Rinnenelements ausgebildet. Die ersten Diffusionsöffnungen im Rinnenflansch gehen jeweils in zugehörige zweite Diffusionsöffnungen in der Seitenwand des Rinnenelements über und bilden Kanäle, die in das Rinnenelement münden. Dadurch wird eine gute Fluidverbindung zwischen der Unterseite der Bodenfliesen bzw. des Bodenbelags und dem Rinnenelement gebildet, sodass die in den Bodenfliesen bzw. dem Bodenbelag enthaltene Feuchtigkeit gut abtrocknen kann.According to the invention, first diffusion openings are formed in the gutter flange and second diffusion openings are formed in a side wall of the gutter element. The first diffusion openings in the gutter flange each merge into associated second diffusion openings in the side wall of the gutter element and form channels that open into the gutter element. This creates a good fluid connection between the underside of the floor tiles or floor covering and the gutter element, so that the moisture contained in the floor tiles or floor covering can dry off easily.

Vorzugsweise ist eine Dichtmanschette mit dem Rahmenflansch verbunden. Besonders bevorzugt ist die Dichtmanschette in verschiedenen Richtungen unterschiedlich stark flexibel. Dies hat den Vorteil, dass die Dichtmanschette in der Richtung flexibel eingestellt werden kann, in der die größte Rinnenarbeit wirkt, um Fugenrisse zur minimieren. Daher ist es besonders bevorzugt, wenn die Dichtmanschette in einer Richtung quer zur Längsachse des Rinnenelements flexibler ist als in einer Richtung parallel zur Längsachse des Rinnenelements.A sealing sleeve is preferably connected to the frame flange. Particularly preferably, the sealing sleeve is flexible to different degrees in different directions. This has the advantage that the sealing sleeve can be flexibly adjusted in the direction in which the greatest gutter work occurs in order to minimize joint cracks. It is therefore particularly preferred if the sealing sleeve is more flexible in a direction transverse to the longitudinal axis of the gutter element than in a direction parallel to the longitudinal axis of the gutter element.

Bei einer weiteren bevorzugten Ausführung ist die Oberfläche des Rinnenelements elektropoliert. Dadurch wird eine lange Glanzbeständigkeit und geringe Schmutzanhaftungen des Rinnenelements erreicht.In a further preferred embodiment, the surface of the channel element is electropolished. This ensures a long gloss retention and low dirt build-up on the channel element.

Vorzugsweise ist ein Ablauftopf an das Rinnenelement angeschweißt. Dadurch wird eine vollwertige Stahlrinne, insbesondere Edelstahlrinne ermöglicht, die schnell und sicher eingebaut werden kann und höchste Ansprüche bezüglich Design und Pflege erfüllt. Der vollverschweißte Ablauftopf bzw. Ablauf schützt den Bodenaufbau dauerhaft vor eindringendem Wasser.A drain pot is preferably welded to the gutter element. This enables a fully-fledged steel gutter, especially stainless steel gutter, which can be installed quickly and safely and meets the highest demands in terms of design and care. The fully welded drain pot or drain permanently protects the floor structure from water penetration.

Mit Blick auf das Herstellungsverfahren wird die Aufgabe durch ein Verfahren zur Herstellung einer erfindungsgemäßen Entwässerungsrinne gelöst, bei dem Diffusionsöffnungen für eine Sekundärentwässerung in ein Rinnenelement eingebracht werden, das wenigstens einen Ablauf für eine Primärentwässerung aufweist. Das Rinnenelement wird mit einem Rahmen durch Durchsetzfügen fest verbunden. Auf die vorstehend im Zusammenhang mit den Diffusionsöffnungen und der festen Verbindung zwischen dem Rahmen und dem Rinnenelement beschriebenen Vorteile wird an dieser Stelle Bezug genommen.With regard to the manufacturing process, the object is achieved by a method for producing a drainage channel according to the invention, in which diffusion openings for secondary drainage are introduced into a channel element which has at least one outlet for primary drainage. The gutter element is firmly connected to a frame by clinching. Reference is made here to the advantages described above in connection with the diffusion openings and the fixed connection between the frame and the channel element.

Mit Blick auf das Einbauverfahren wird die Aufgabe durch ein Verfahren zum Einbau einer erfindungsgemäßen Entwässerungsrinne gelöst, bei dem eine Flüssigabdichtung entweder mit Abstand vor der Einrichtung zur Sekundärentwässerung derart aufgebracht wird, dass die Einrichtung zur Sekundärentwässerung im eingebauten Zustand geöffnet ist. Alternativ wird die Flüssigabdichtung derart aufgebracht, dass die Einrichtung zur Sekundärentwässerung überdeckt und verschlossen wird. Dies betrifft in erster Linie die Diffusionsöffnungen, die auf diese Weise aktiviert oder deaktiviert werden können, je nachdem, ob eine Sekundärentwässerung gewünscht ist oder nicht.With regard to the installation method, the task is solved by a method for installing a drainage channel according to the invention, in which a liquid seal is either applied at a distance in front of the device for secondary drainage in such a way that the device for secondary drainage is open in the installed state. Alternatively, the liquid waterproofing is applied in such a way that the secondary drainage device is covered and closed. This primarily concerns the diffusion openings, which can be activated or deactivated in this way depending on whether secondary drainage is desired or not.

Die Erfindung wird nachfolgend unter Bezug auf die beigefügten Figuren anhand von Ausführungsbeispielen mit weiteren Einzelheiten näher beschrieben.The invention is described in more detail below with reference to the attached figures using exemplary embodiments with further details.

Die in den Figuren dargestellte Entwässerungsrinne kommt für die Entwässerung in Sanitärbereichen und/oder Terrassenbereichen zum Einsatz. Die Entwässerungsrinne wird in Fliesenböden oder in Böden mit Natursteinbelägen eingebaut, bei denen zusätzlich zur Primärentwässerung eine Sekundärentwässerung bedeutsam sein kann. Die Entwässerungsrinne ist in erster Linie für Duschen konzipiert und kann als Duschrinne bezeichnet werden. Andere Anwendungsmöglichkeiten im Sanitärbereich sind denkbar.The drainage channel shown in the figures is used for drainage in sanitary areas and/or terrace areas. The drainage channel is installed in tiled floors or in floors with natural stone coverings, where secondary drainage can be important in addition to primary drainage. The drainage channel is primarily designed for showers and can be called a shower channel. Other possible applications in the sanitary sector are conceivable.

Die Entwässerungsrinne weist ein Rinnenelement 10 mit einer im wesentlichen rechteckigen Form auf. Im Boden des Rinnenelements 10 ist ein Ablauf 11 ausgebildet. Der Boden ist in an sich bekannter Weise geneigt, sodass der Ablauf 11 an der tiefsten Stelle des Rinnenelements angeordnet ist. Es ist möglich, mehr als einen Ablauf 11 vorzusehen, insbesondere bei längeren Entwässerungsrinne.The drainage channel has a channel element 10 with a substantially rectangular shape. A drain 11 is formed in the bottom of the channel element 10. The floor is inclined in a manner known per se, so that the drain 11 is arranged at the lowest point of the channel element. It is possible to provide more than one drain 11, especially for longer drainage channels.

Durch den Ablauf 11 erfolgt die Primärentwässerung.Primary drainage takes place through drain 11.

Das Rinnenelement 10 weist Seitenwände 19 auf, die sich im Wesentlichen senkrecht zum Boden des Rinnenelements 10 erstrecken und, wie in den Figuren 1, 2 gut zu erkennen, einen Überstand bilden. Der Überstand entspricht im Wesentlichen der Anschlusshöhe der Bodenfliesen bzw. des Bodenbelags. Die Seitenwände 19 sind jeweils mit einem Rinnenflansch 15 verbunden, insbesondere einstückig verbunden, der sich senkrecht zu den Seitenwänden 19 nach außen erstreckt.The gutter element 10 has side walls 19 which extend substantially perpendicular to the bottom of the gutter element 10 and, as shown in FIGS Figures 1, 2 easy to see, forming a supernatant. The overhang essentially corresponds to the connection height of the floor tiles or floor covering. The Side walls 19 are each connected to a gutter flange 15, in particular connected in one piece, which extends outwards perpendicular to the side walls 19.

Das Rinnenelement 10 ist in bzw. an einem Rahmen 12 angeordnet, der einen Rahmenflansch 13 aufweist, und mit diesem fest verbunden. Der Rahmenflansch 13 erstreckt sich senkrecht zur den Seitenwänden 19 des Rinnenelements 10. Im eingebauten Zustand sind der Rahmenflansch 13 und der Rinnenflansch 15 horizontal angeordnet.The gutter element 10 is arranged in or on a frame 12, which has a frame flange 13, and is firmly connected to it. The frame flange 13 extends perpendicular to the side walls 19 of the gutter element 10. When installed, the frame flange 13 and the gutter flange 15 are arranged horizontally.

Wie in Figuren 1, 2 zu erkennen, weist das Rinnenelement 10 eine Einrichtung für die Sekundärentwässerung 14 auf. Die Einrichtung für die Sekundärentwässerung 14 dient dazu, die Diffusion von Feuchtigkeit bzw. Wasser zu ermöglichen, die sich unterhalb bzw. in den Bodenfliesen bzw. im Bodenbelag bspw. aufgrund beschädigter Fliesenfugen angesammelt hat.As in Figures 1, 2 To recognize, the gutter element 10 has a device for secondary drainage 14. The device for secondary drainage 14 serves to enable the diffusion of moisture or water that has accumulated below or in the floor tiles or in the floor covering, for example due to damaged tile joints.

Die Einrichtung für die Sekundärentwässerung 14 ist in der Form von Diffusionsöffnungen 17, 18 ausgebildet. Die Diffusionsöffnungen 17, 18 befinden sich im Rinnenelement 10, konkret im Rinnenflansch 15 sowie in den Seitenwänden 19 des Rinnenelements 10. Die Diffusionsöffnungen 17, 18 bilden also integralen Bestandteil des Rinnenelements 10.The device for secondary drainage 14 is designed in the form of diffusion openings 17, 18. The diffusion openings 17, 18 are located in the gutter element 10, specifically in the gutter flange 15 and in the side walls 19 of the gutter element 10. The diffusion openings 17, 18 therefore form an integral part of the gutter element 10.

Dabei sind mehrere Diffusionsöffnungen 17, 18 entlang der längeren Seitenwände 19 des Rinnenelements 10 angeordnet, beispielsweise 7 Diffusionsöffnungen 17, 18. Eine andere Anzahl ist möglich. Die Diffusionsöffnungen 17, 18 sind auf beiden längeren Seiten der Entwässerungsrinne angeordnet. Es ist auch möglich, auf den kürzeren Seiten (Stirnseiten) der Entwässerungsrinne Diffusionsöffnungen 17, 18 auszubilden.Several diffusion openings 17, 18 are arranged along the longer side walls 19 of the channel element 10, for example 7 diffusion openings 17, 18. A different number is possible. The diffusion openings 17, 18 are arranged on both longer sides of the drainage channel. It is also possible to form diffusion openings 17, 18 on the shorter sides (end faces) of the drainage channel.

Der Aufbau der Diffusionsöffnungen 17, 18 ist in den Figuren 3, 4 in Detail gezeigt.The structure of the diffusion openings 17, 18 is in the Figures 3, 4 shown in detail.

Wie in Fig. 3 zu sehen, ist im Rinnenflansch 15 eine erste Diffusionsöffnungen 17 ausgebildet. Die erste Diffusionsöffnungen 17 bildet einen länglichen Durchbruch durch den Rinnenflansch 15, der unten durch die Oberseite des Rahmenflansches 13 begrenzt ist. Die ersten Diffusionsöffnungen 17 erstreckt sich im Wesentlichen senkrecht zur Längsachse des Rinnenelements 10.As in Fig. 3 As can be seen, a first diffusion opening 17 is formed in the gutter flange 15. The first diffusion openings 17 forms an elongated opening through the gutter flange 15, which extends through the top of the frame flange 13 is limited. The first diffusion openings 17 extend essentially perpendicular to the longitudinal axis of the channel element 10.

Wie in Fig. 4 zu erkennen, ist eine zweite Diffusionsöffnungen 18 in der Seitenwand 19 des Rinnenelements ausgebildet. Die erste Diffusionsöffnungen 17 im Rinnenflansch 15 geht in die zweite Diffusionsöffnungen 18 in der Seitenwand 19 über und bildet so einen Kanal 20, der die Außenseite des Rinnenelements mit dessen Innenseite verbindet. Wie in Fig. 3 gut zu erkennen, ist der Kanal 20 ein länglicher Schlitz, der sich im Wesentlichen senkrecht zur Längsrichtung des Rinnenelements 10 im Bereich der längeren Seite erstreckt. Wie in Fig. 1 gut zu erkennen, sind pro Längsseite des Rinnenelements mehrere gleichartige Kanäle 20 ausgebildet, die sich jeweils parallel zueinander und quer zur Längsachse des Rinnenelements 10 erstrecken. Die einzelnen Kanäle 20 sind jeweils entsprechend ausgebildet, weisen also erste und zweite Diffusionsöffnungen 17, 18, wie oben beschrieben, auf.As in Fig. 4 As can be seen, a second diffusion opening 18 is formed in the side wall 19 of the channel element. The first diffusion openings 17 in the gutter flange 15 merges into the second diffusion openings 18 in the side wall 19 and thus forms a channel 20 which connects the outside of the gutter element with its inside. As in Fig. 3 clearly visible, the channel 20 is an elongated slot which extends essentially perpendicular to the longitudinal direction of the channel element 10 in the area of the longer side. As in Fig. 1 clearly visible, several similar channels 20 are formed per longitudinal side of the channel element, each of which extends parallel to one another and transversely to the longitudinal axis of the channel element 10. The individual channels 20 are each designed accordingly, i.e. have first and second diffusion openings 17, 18, as described above.

Die Funktion der Diffusionsöffnungen 17, 18 besteht darin, die unter oder in den Bodenfliesen bzw. im Bodenbelag angesammelte Feuchtigkeit bzw. angesammeltes Wasser nach außen in die Umgebung zu diffundieren. Dazu sind die Kanäle 20 so im Rinnenflansch 15 ausgebildet, dass diese mit den an die Entwässerungsrinne unmittelbar angrenzenden Bodenfliesen teilweise überlappen. Dadurch entsteht eine Fluidverbindung von den Bodenfliesen bzw. vom Bodenbelag über die Kanäle 20 ins Innere des Rinnenelements 10 und somit in die Umgebung.The function of the diffusion openings 17, 18 is to diffuse the moisture or water accumulated under or in the floor tiles or in the floor covering outwards into the environment. For this purpose, the channels 20 are designed in the gutter flange 15 so that they partially overlap with the floor tiles immediately adjacent to the drainage gutter. This creates a fluid connection from the floor tiles or floor covering via the channels 20 into the interior of the channel element 10 and thus into the environment.

Zusätzlich oder alternativ zu den Diffusionsöffnungen 17, 18 kann die Entwässerungsrinne an der Unterseite des Rahmens 12 bzw. des Rahmenflansches 13 Einrichtungen zur Sekundärentwässerung 14 aufweisen, die in den Figuren nicht dargestellt sind. Die Einrichtung zur Sekundärentwässerung 14 an der Unterseite des Rahmens 12 bzw. des Rahmenflansches 13 können als punktuelle Profilierung ausgebildet sein, die über die Unterseite des Rahmens vorstehen. Diese Profilierung bildet mehrere Abstandshalter, die auf einer Unterlage aufstehen und zwischen der Unterlage und der Unterseite des Flansches 13 einen Hohlraum bilden, durch den Flüssigkeit bzw. Wasser nach außen diffundieren kann. Bei dem Ausgangsbeispiel gemäß Figuren 1 bis 6 ist diese Möglichkeit der Sekundärentwässerung zusätzlich zu den Diffusionsöffnungen 17, 18 vorgesehen.In addition or as an alternative to the diffusion openings 17, 18, the drainage channel on the underside of the frame 12 or the frame flange 13 can have devices for secondary drainage 14, which are not shown in the figures. The device for secondary drainage 14 on the underside of the frame 12 or the frame flange 13 can be designed as a punctual profiling that protrudes over the underside of the frame. This profiling forms several spacers that stand on a base and form a cavity between the base and the underside of the flange 13 through which liquid or water can diffuse to the outside. In the initial example according to Figures 1 to 6 is This possibility of secondary drainage is provided in addition to the diffusion openings 17, 18.

Die Profilierung der Unterseite des Rahmenflansches 13 erfolgt durch die Punktverbindungen, die das Rinnenelement 10 und den Rahmen 12 fest verbinden.The underside of the frame flange 13 is profiled by the point connections that firmly connect the gutter element 10 and the frame 12.

Dazu ist der Rinnenflansch 15 des Rinnenelements 10 in einer entsprechenden Ausnehmung 16 an der Oberseite des Rahmenflansches 13 planparallel zum Rahmenflansch 13 angeordnet. In Fig. 4 zu sehen, ist die Tiefe der Ausnehmung 16 etwas größer als die Höhe des Rinnenflansches 15 ist, sodass der Rinnenflansch 15 vollständig in der Ausnehmung 16 aufgenommen ist. Es genügt, wenn der Rinnenflansch 15 bündig mit der Oberseite des Rahmenflansches 13 abschließt. Es kommt dabei lediglich darauf an, dass eine plane Oberseite des Rahmenflansches gebildet wird, auf der planparallel die Bodenfliesen angeordnet werden können.For this purpose, the gutter flange 15 of the gutter element 10 is arranged in a corresponding recess 16 on the top of the frame flange 13, plane-parallel to the frame flange 13. In Fig. 4 As can be seen, the depth of the recess 16 is slightly greater than the height of the gutter flange 15, so that the gutter flange 15 is completely accommodated in the recess 16. It is sufficient if the gutter flange 15 is flush with the top of the frame flange 13. All that matters is that a flat top side of the frame flange is formed on which the floor tiles can be arranged in a plane-parallel manner.

Die Punktverbindungen zwischen dem Rinnenelement 10 und dem Rahmen 12 erfolgen durch Durchsetzfügen. Dabei wird eine druckknopfartige, formschlüssige Verbindung zwischen dem Rinnenflansch 15 und dem Rahmenflansch 15 in einem Kaltumformprozess hergestellt.The point connections between the gutter element 10 and the frame 12 are made by clinching. A push-button-like, positive connection is produced between the gutter flange 15 and the frame flange 15 in a cold forming process.

Ein Durchsetzfügewerkzeug besteht, wie bekannt, aus einem Stempel und einer Matrize. Die zu verbindenden Teile werden durch den Stempel ähnlich wie beim Tiefziehen unter plastischer Deformation in die Matrize gedrückt. Durch die Form der Matrize entsteht eine druckknopfähnliche Verbindung, die die Teile form- und kraftschlüssig miteinander verbindet.As is known, a clinching tool consists of a punch and a die. The parts to be connected are pressed into the die by the punch, similar to deep drawing, with plastic deformation. The shape of the die creates a connection similar to a push button, which connects the parts together in a positive and non-positive manner.

Die druckknopfähnliche Kontur der Verbindung steht an der Unterseite des Rahmenflansches 13 vor und bildet eine Profilierung. Die Profilierung dient als Abstandshalter, wenn der Rahmenflansch 13 auf eine Unterlage beim Einbau der Entwässerungsrinne aufgelegt wird. Durch die Abstandshalter wird zwischen der Unterlage und dem Rahmenflansch 13 ein kleiner Spalt bzw. Hohlraum gebildet, durch den die Feuchtigkeit diffundieren kann. Die Profilierung bildet also eine Einrichtung zur Sekundärentwässerung 14, die integral im Rahmenflansch 13 ausgebildet ist.The push-button-like contour of the connection protrudes from the underside of the frame flange 13 and forms a profile. The profiling serves as a spacer when the frame flange 13 is placed on a base when installing the drainage channel. The spacers form a small gap or cavity between the base and the frame flange 13 through which the moisture can diffuse. The profiling therefore forms a device for secondary drainage 14, which is formed integrally in the frame flange 13.

In Fig. 3 ist gut zu sehen, dass die Integration der Einrichtung für die Sekundärentwässerung 14 in das Rinnenelement 10 dazu führt, dass die Innenwand des Rinnenelements 10 im Wesentlichen frei von Hinterschneidungen ist. Da das Rinnenelement 10 auch im übrigen einbautenfrei ist, kann dieses völlig problemlos mit einem Tuch gereinigt werden, ohne dass dafür spezielle Reinigungsutensilien erforderlich sind.In Fig. 3 It can be clearly seen that the integration of the device for secondary drainage 14 into the gutter element 10 results in the inner wall of the gutter element 10 being essentially free of undercuts. Since the gutter element 10 is otherwise free of installations, it can be easily cleaned with a cloth without the need for special cleaning utensils.

Wie in Fig. 5 dargestellt, ist der Rahmenflansch 13 mit einer Dichtmanschette 21 verbunden. Die Dichtmanschette 21 ist hochreißfest und dehnungsfähig. Konkret ist die Dehnungsrichtung der Dichtmanschette isotrop. Die Dichtmanschette lässt sich in einer Richtung quer zur Längsachse des Rinnenelements 10 weiter dehnen als in einer Errichtung parallel zur Längsachse des Rinnenelements.As in Fig. 5 shown, the frame flange 13 is connected to a sealing sleeve 21. The sealing sleeve 21 is highly tear-resistant and stretchable. Specifically, the direction of expansion of the sealing sleeve is isotropic. The sealing sleeve can be stretched further in a direction transverse to the longitudinal axis of the gutter element 10 than in a direction parallel to the longitudinal axis of the gutter element.

Die Entwässerungsrinne ist aus elektropoliertem Edelstahl hergestellt. Der Ablauftopf 22 ist mit dem Rinnenelement 10 verschweißt.The drainage channel is made of electropolished stainless steel. The drain pot 22 is welded to the gutter element 10.

Beim Einbau der Entwässerungsrinne bestehen verschiedene Möglichkeiten. Wird eine Sekundärentwässerung gewünscht, dann kann eine Flüssigabdichtung (nicht dargestellt) so aufgebracht werden, dass die Diffusionsöffnungen 17, 18 frei bleiben. In die Sekundärentwässerung ist dann möglich. Die Bodenfliesen werden bis an die Seitenwand 19 verlegt, sodass diese die Diffusionsöffnungen 17, 18 überdecken.There are various options when installing the drainage channel. If secondary drainage is desired, then a liquid seal (not shown) can be applied so that the diffusion openings 17, 18 remain free. Secondary drainage is then possible. The floor tiles are laid up to the side wall 19 so that they cover the diffusion openings 17, 18.

Wird keine Sekundärentwässerung gewünscht, dann wird eine Dichtung, beispielsweise wie in Fig. 6 gezeigt in die Kehle zwischen dem Rinnenflansch 15 unter Seitenwand 19 eingebracht, die die Diffusionsöffnungen 17, 18 verschließt. Es ist auch möglich, die Flüssigabdichtung bis zur Seitenwand 19 aufzubringen sodass auch dadurch die Diffusionsöffnungen 17, 18 verschlossen werden. Die Sekundärentwässerung ist damit weitgehend deaktiviert.If no secondary drainage is desired, then a seal, for example as in Fig. 6 shown in the throat between the gutter flange 15 under side wall 19, which closes the diffusion openings 17, 18. It is also possible to apply the liquid seal up to the side wall 19 so that the diffusion openings 17, 18 are also closed. The secondary drainage is therefore largely deactivated.

Die Erfindung ist vorliegend anhand horizontaler Rahmenflansche dargestellt und erläutert. Es ist auch möglich, für eine wandnahe Montage einen Rahmenflansch aufzukannten. Die Diffusionsöffnungen 17, 18 funktionieren in der vorgeschriebenen Weise.The invention is illustrated and explained here using horizontal frame flanges. It is also possible to use a frame flange for installation close to the wall. The diffusion openings 17, 18 function in the prescribed manner.

Wie in Figuren 5, 6 dargestellt, weist die Entwässerungsrinne eine Höhenverstellung 24 auf.As in Figures 5, 6 shown, the drainage channel has a height adjustment 24.
