Description

The invention relates to a drainage channel arrangement with a drainage channel and a sealing sleeve according to the preamble of claim 1. The invention further relates to a set for realizing a drainage channel arrangement according to claim 15 and the use of a drainage channel arrangement according to claim 16.

Generic drainage channel arrangements comprise a drainage channel, which can be designed, for example, as a shower channel, and are used, for example, in room showers, public toilets or commercial kitchens for removing water. An essential element of such generic gutter arrangements is the gutter. The drainage channel has a horizontally flat channel bottom with an upper and a lower side, with “above” and “below” naturally referring to directions along the vertical. The drainage channel is usually trough-shaped, that is to say that channel walls are arranged on the top of the channel bottom, which extend vertically upward from the channel bottom and thus, together with the channel bottom, form a channel shape in which water is collected for drainage. On the underside of the channel bottom there is a channel socket which extends vertically downward from the channel bottom and which circumferentially closes a drain opening provided in the channel bottom encloses. In most cases, exactly one drain opening and exactly one gutter connector assigned to it are provided for the drain gutter. However, there are also generic drainage channel arrangements with a plurality of drainage openings and a plurality of drainage spigots, each drainage spigot being assigned to exactly one of the drainage openings and enclosing it in a closed manner. This can be advantageous for ensuring a high drain rate. The drainage channel can therefore have, in addition to the one channel connector and the one outlet opening, further channel connectors and respectively assigned outlet openings. The horizontally flat channel floor is often not flat, but has a slope along one or more horizontal directions to the drain opening. In any case, however, the channel floor extends over a considerable horizontal area. The gutter is usually elongated in a first horizontal direction, that is to say that it has a length in the first horizontal direction that is at least 5 times, in particular at least 10 times, its length in a second horizontal direction, the second horizontal direction is preferably perpendicular to the first horizontal direction. However, gutters of generic gutter arrangements are known which extend in the two horizontal directions mentioned with the same length. The gutter walls discussed above run along a vertical that is perpendicular to the horizontal, that is, perpendicular to all horizontal directions, and the gutter walls typically have a length along the vertical that is less than one-tenth the length of the gutter in the first horizontal direction is. Typically, the length of the gutter in the first horizontal direction is between 70 cm and 200 cm and the length of the gutter in the second horizontal direction is between 3 cm and 15 cm and the length of the gutter walls along the vertical between 1 cm and 7 cm. The drainage channel is often made from a one-piece sheet by means of a forming and / or welding process. In any case, the trough-shaped drainage channel is suitable for collecting water and dispensing it through the drainage opening.

A generic drainage channel arrangement also has a sealing sleeve which forms a sealing tub with a tub bottom in which the drainage channel lies. The sealing trough has a trough connecting piece, which encloses an opening provided in the trough bottom in a circumferentially closed manner. H. at least aligned with the clear cross section of this opening. In some embodiments, the channel spout also overlaps axially with the tub spout, so that it also extends axially within the tub spout. In addition, a generic gutter arrangement has a drain pot. The drain pan is designed in such a way and can be arranged as a drainage channel and sealing sleeve that the trough neck opens into it and that it is sealed around the outside of the trough neck against the sealing trough. In particular, the drain pot is arranged in every intended operating and assembly position so that the tub connector opens into it and it is sealed around the outside of the tub connector against the sealing pan.

The described design of generic drainage channel arrangements serves the purpose that a room floor, which is finished in the fine construction and in which the drainage channel arrangement is integrated, can be reliably sealed watertight. For this purpose, two different sealing levels are usually provided: the provision of a first sealing level is carried out by sealing the screed of the room floor, which can be done, for example, with a sealing coat with a paste, a flocked sealing membrane or a welding membrane. The sealing collar, which forms the sealing trough in which the drainage channel lies, is integrated into this first sealing level. It goes without saying that the drainage channel of the drainage channel arrangement projects vertically beyond the sealing collar and thus only has a lower section in the sealing trough formed by the sealing collar. The second sealing level is formed on the surface of the room floor, and the drainage channel is integrated into this second sealing level. The surface is usually formed by a floor finish, such as tiles, which is then connected in a watertight manner around the drainage channel to the top of the drainage channel via a seal, usually a silicone seal. When a generic gutter arrangement is used as intended, water, which is located on the surface of the room floor, is guided to the gutter via the second sealing level and from there is discharged into the drain pot via the drain opening. A drain pipe is connected to the drain pot, through which the water can be drained into the sewage system. The first sealing level serves to prevent the penetration of water into the room floor as far as possible in order to prevent structural damage caused by water ingress as far as possible. A risk of such water penetration can exist, for example, in that a seal that connects the bottom edge to the drainage channel has leaks due to age, so that water can get between the bottom edge and the drainage channel. Leakages can also occur in the floor finish itself, for example in tile joints, through which water can reach the top of the screed from the surface of the room floor. The first sealing level is essential for all of these purposes. By continuing the first sealing level from the sealing of the screed to the sealing sleeve forming the sealing trough, it is ensured that such water can collect in the sealing trough and does not penetrate into the room floor. Thanks to the seal between the drain pan and the sealing pan, it is also ensured that if the drain pan is clogged, no water can escape between the drain pan and the sealing pan and get into the room floor from there.

In the state of the art, however, it has proven to be problematic to remove water that is jammed at the first sealing level, in particular in the sealing trough. So-called "seepage water openings" are selected as the means of choice in the prior art. These leachate openings are mostly provided in the drain near their vertical upper end. If water accumulates at the first sealing level, it can enter the drainage channel from the outside through the leachate openings and from there into the drainage pot and thus into the sewage system. Such leachate water openings are usually provided so far above the channel floor in the drainage channel that when the drainage channel arrangement is used as intended for the removal of water from the surface of the room floor, the water does not emerge from the drainage channel via the leachate water openings but is to be discharged directly into the drain pan via the drain opening. The problem here is that if a drain is blocked, for example in the drain pot or in a drain pipe, it can happen that water that has accumulated emerges from the drain gutter through the seepage water openings between the first and second sealing levels. In addition, it is problematic that even in normal operation, in which considerable amounts of water have to be removed from a room floor surface, water can accumulate in the drainage channel before it flows into the drain pan, whereby even such a build-up can lead to water collected in the gutter emerging from the leachate openings and reaching between the first and second sealing levels. In addition, it is problematic that if the leachate openings are spaced as far as possible from the channel floor, a considerable build-up of water on the first sealing level is necessary until it can reach the drain opening in the channel via the leachate openings and can be removed from there. The prior art includes drainage channel arrangements from the documents US 9,107,545 B1 , DE 103 60 310 A1 , WO 2009/144479 A1 and EP 1 674 629 A2 known. US 9,107,545 B1 discloses a shower tray, in which a drain channel is inserted, which is held on a mounting plate on a drain body, wherein the drain channel and the drain body are sealed against the shower tray. DE 103 60 310 A1 discloses a gutter arrangement in which a gutter is sealingly fixed to a drain body. WO 2009/144479 A1 discloses a gutter arrangement in which a gutter is sealed against a drain body and a sealing sleeve. EP 1 674 629 A2 discloses a gutter arrangement in which a gutter is sealed horizontally movable relative to a drain body.

The present invention is based on the object of providing a drainage channel arrangement which fulfills the above-described purpose of generic drainage channel arrangements and thereby at least partially eliminates the difficulties and disadvantages which arise in the case of generic drainage channel arrangements. The invention is also based on the object of providing a set for realizing a drainage channel arrangement according to the invention and to provide a use of a drainage channel arrangement according to the invention with the purpose of generic drainage channel arrangements described above can be fulfilled as simply and reliably as possible.

As a solution to the described problem underlying the invention, the invention proposes a drainage channel arrangement with the features of claim 1. The drainage channel arrangement according to the invention comprises, as explained above for generic drainage channel arrangements, a drainage channel and a sealing sleeve, the drainage channel having a horizontally flat channel bottom with an upper and a lower side, a channel connector being arranged on the underside of the channel bottom and extending from the channel bottom extends vertically downwards and encloses a drain opening provided in the groove bottom in a circumferentially closed manner. The drainage channel particularly preferably has a length in a first horizontal direction which is at least 5 times, in particular at least 10 times its length in a second horizontal direction. The sealing sleeve forms a sealing trough with a trough bottom, in which the drainage channel lies, the sealing trough having a trough neck, which encloses an opening provided in the trough bottom in a closed manner, within which the trough neck is arranged. The drainage channel arrangement also has a drainage pot, which is designed and can be arranged relative to the drainage channel and sealing sleeve so that in any operating position and in particular in every mounting position, the tub connection piece opens into it and it is sealed around the outside of the tub connection piece against the sealing tub. The drainage channel arrangement according to the invention can have further features which were explained above with reference to drainage channel arrangements of the generic type. It is essential that the drainage channel is designed to collect water and dispense it via its drainage opening, and that the sealing sleeve is designed to collect water in the sealing trough which it forms, and that the channel connection piece is so lies within the trough connection, that it opens into this, that is, with respect to the horizontal direction, its clear cross section lies within the clear cross section of the trough connection. Tub spout and channel spout can overlap axially, ie along their vertical course. It is also essential that the drain pot is watertightly sealed with respect to the sealing trough, which is formed by the sealing sleeve, in every intended operating position by means of a seal which at any rate is closed around the trough neck. The term "watertight" preferably means that in a test according to DIN EN 1253, part 1, as of March 2015, the drainage channel arrangement, when used as intended, prevents water from escaping at the points sealed as "watertight".

The drainage channel arrangement according to the invention also has a sealing device which has a first sealing section, a second sealing section and a connecting section. The first sealing section and the second sealing section are preferably provided by at least one sealing element, which is a separate element from the above-mentioned seal between the sealing trough and the drain pot. In a first operating position of the drainage channel arrangement according to the invention, the first sealing section lies in a watertight sealing manner both on the channel connection piece and on the connecting section, and in the first operating position the second sealing section lies on both the tub connecting piece and the connecting section in a watertight manner in order to form a sealed collecting volume between tub spout and gutter spout. In the first operating position, the first sealing section is particularly preferably in a closed, watertight, sealing manner around the drain opening and on the connecting section around the drain opening. In the first operating position, the second sealing section is particularly preferably in contact with the trough neck and the connecting section in a closed, watertight manner around the drain opening. Accordingly, in this preferred embodiment, a collecting volume that is closed between the tub connector and the channel connector is formed. This collecting volume is designed to collect water that runs vertically into the collecting volume from above, so that it cannot exit this collecting volume vertically downwards. In the first operating position, the connecting section connects the two sealing sections in a watertight manner to one another via a releasable connection, in order to ensure the formation of the sealed collecting volume between the tub connector and the channel connector. In a second operating position, the releasable connection is released, with a by releasing the releasable connection Passage opening between the collecting volume and the opening provided in the tub floor is released. The passage opening thus enables the opening provided in the tub floor to be connected to the collecting volume, whereas the passage opening is closed in the first operating position, in which the two sealing sections are connected to one another in a watertight manner via the connecting section, so that the opening provided in the tub floor is not included communicated the collection volume. The connection is preferably reversibly detachable, ie the drainage channel arrangement according to the invention can be moved from the first operating position to the second operating position and back to the first operating position as often as desired. Via the connecting section, the channel spout and the tub spigot are preferably connected to one another so that the collecting volume can be formed. The sealing sections ensure the watertight sealing of the connecting section to the channel spout and trough spigot, so that water can be collected in the collecting volume, which in the second operating position can then be discharged in a targeted manner via the passage opening. The detachable connection can be ensured, for example, by a frictional connection or by a positive connection, for example by providing a plastic connecting section in which a closable passage window is provided. Alternatively, for example, the connecting section can be provided by a rigid element, which, in the first operating position, latches or jams with both sealing sections and which can be released from both sealing sections while opening the passage opening.

The present invention has significant advantages over the prior art. On the one hand, the provision of a collecting volume between the tub connector and the channel connector ensures that water that explained above runs on the first sealing level towards the gutter, in which collecting volume can collect and is thus prevented from penetrating the floor of the room. On the other hand, the provision of the collecting volume between the tub connector and the channel connector ensures that the water can collect as deeply as possible below the surface of the room floor, so that there can be no water retention above the screed at the first sealing level. In addition, the releasable connection between the two sealing sections and the connecting section ensures that the passage opening is only opened in a targeted manner in the second operating position of the drainage channel arrangement according to the invention, so that water can only reach the opening provided in the trough bottom in this second operating position . This can also be particularly effective in preventing water from accumulating in the drain pan when the drain pan or a drain pipe is blocked and from getting between the gutter socket and the tub socket from there. The drainage channel arrangement according to the invention thus enables on the one hand the reliable collection of so-called "leachate" in the collecting volume, on the other hand the targeted delivery of this leachate via the passage opening into the drain pan and also prevents water from penetrating between the first and second sealing levels in the event of a blockage of the Drain pot and / or a drain pipe connected therein. In addition, the drainage channel arrangement according to the invention enables the formation of a flangeless drainage channel. Because the drainage channel is arranged in the sealing trough of the sealing sleeve and the sealing sleeve is integrated in the first sealing level, there is no need in the prior art to provide a flange on the drainage channel, by means of which this can be connected to a sealing mat (e.g. By gluing) and then with a waterproof covering, which is provided on a screed, can be connected. As a result, the installation options of the drainage channel according to the invention are considerably expanded, and the drainage channel of the drainage channel arrangement according to the invention can in particular also be installed in close proximity to a wall. In general, at least a lower section of the drainage channel, in particular at least the channel floor, preferably lies within the vertical extent of the sealing trough, and generally the drainage channel preferably lies at least horizontally within the sealing trough. It is essential that the sealing trough, at least in the first operating position, can perform a water collecting function below the drainage channel. In general, according to the invention, a flangeless design of the channel walls can be provided in such a way that the channel walls have an extension along the specific horizontal direction at their vertical end pointing away from the channel bottom, in which they form a termination of the drain channel with their flat traveling extension, which is less than 2 cm , in particular less than 1 cm.

In one embodiment, the sealing sleeve extends by at least 5 cm, in particular by at least 10 cm beyond all horizontal ends of the channel bottom. The sealing sleeve thus has a horizontal end which is closed around the drainage channel and which is always spaced over the entire circulation by at least 5 cm from the horizontal extent of the channel bottom. This ensures that the sealing collar has a sufficiently wide edge area, via which it can be reliably connected to adjacent waterproof coverings, for example by gluing or welding. In one embodiment, the sealing collar has a hard shell section which forms the sealing trough, and a mat section which extends horizontally around the hard shell section and which is sealingly connected to the hard shell section via a closed peripheral sealing line. Of course, the sealing line runs around the drain opening and in particular outside the drain gutter. A robust sealing trough can be provided via the hard shell section, and a closed circumferential seal between the mat section and the hard shell section can be ensured via the sealing line, the mat section being designed for sealing connection to another sealed surface, such as for example a sealed wall or a sealed screed can. The mat section particularly preferably extends by at least 5 cm, in particular by at least 10 cm beyond all horizontal ends of the channel bottom, in particular beyond all horizontal ends of the hard shell section. The hard shell section can be produced, for example, by injection molding and / or can consist of a rigid material, in particular of rigid plastic. The mat section is preferably designed as a flat membrane which has a thickness of less than 3 mm, in particular less than 2 mm, in particular less than 1 mm. The mat section can, for example, be a material such as nitrile rubber (NBR), ethylene-propylene-diene rubber (EPDM), styrene-butadiene rubber (SBR), thermoplastic elastomers (TPE), polyethylene (PE), polyethylene with a polypropylene flocking ( PP), or comprise polyvinyl chloride (PVC), for example consist of at least 70% of one of these materials, with the percentage being based on mass. The mat section is preferably designed to be elastic at least along one of its planar extension directions.

In one embodiment, the second sealing section is arranged below the first sealing section in the first operating position. The is particularly preferred second sealing section arranged in the first operating position below the lower end of the channel connector, particularly preferably below the first sealing section and below the lower end of the channel connector. This embodiment is particularly well suited to arranging the collecting volume as far down as possible, so that the leachate can be collected as well as possible in the collecting volume and leachate can run off as well as possible into the collecting volume. In addition, this embodiment can make it possible for the collected leachate to drain as completely as possible through the passage opening when the releasable connection between the sealing section and the connecting section is released. For this purpose, the passage opening is particularly preferably provided below the channel connector. The passage opening in the second operating position particularly preferably extends upward from the second sealing section, particularly preferably from the second sealing section to the first sealing section. At this point, it should be noted that, when used as intended, the drainage channel arrangement is integrated into a room floor in such a way that the vertical runs along the weight force acting on the earth, the horizontal, of course, running perpendicular to the vertical.

In one embodiment, the connecting section is formed at least in sections by the gutter socket and / or at least in sections by an element separate from the gutter and from the sealing sleeve. For example, the connecting section can comprise a tubular element, the first sealing section being provided on the inside of the channel connector and the second sealing section on the inside of the trough connector and in the first operating position the tubular element abutting both sealing sections and sealingly connecting them to one another and in the second operating position the tubular element the neck is removable and thus a free passage opening is formed between the two sealing sections. In another embodiment, for example, the second sealing section can permanently connect the connecting section and the trough connection to one another, the first sealing section being latched to the connecting section in the first position and being detached from the connecting section in the second operating position. In the first operating position it covers the passage opening, in the second operating position the passage opening is released. In this latter embodiment, for example, the connecting section can be formed by the channel connector, wherein the passage opening can be provided in the channel connector and can be closed by the sealing section. In general, the passage opening is particularly preferably arranged below the channel bottom, and particularly preferably the lower end of the passage opening is less than 2 cm, in particular less than 1 cm above the lower end of the channel connector, in particular below the channel connector. The connecting section is particularly preferably designed as an immersion tube which, in the first operating position, is arranged inside the gutter socket and inside the trough socket, with both sealing sections abutting on the outside of the immersion tube in the first operating position and with the immersion tube being vertically displaceable and at least in the second operating position does not lie continuously over its outer circumference on the second sealing section or the second sealing section at least not continuously over its outer circumference on the trough connection. This ensures that the passage opening can be formed at the transition points of the tub socket - second sealing section or second sealing section - dip tube, which can make it possible for the passage opening to be arranged as deeply as possible, so that as much as possible is collected Leachate can drain through the passage opening. In one embodiment, in the first operating position, the first sealing section rests on the inside of the channel spigot and the second sealing section on the inside of the tub spigot, with a further seal for sealing the tub spigot against the drain pan on the outside of the tub spigot. In very general terms, the seal via which the tub connector is sealed off from the drain pot is preferably a sealing element separate from the first and second sealing sections. In one embodiment, the first and the second sealing section are provided on separate sealing elements. In one embodiment, the sealing sections are formed by a common sealing element which has the two sealing sections and a sealing element section which connects the sealing sections and which has a cutout to ensure the passage opening. This embodiment can enable a particularly simple and, at the same time, robust assembly of the drainage channel arrangement and, moreover, cost-effective production, since both sealing element sections and the passage opening in between can be formed with only one sealing element. The sealing elements forming the sealing sections or the sealing element forming the sealing sections are preferably fixed in position in both the first and in the second operating position on at least one of the three components of the drainage channel arrangement, tub connector, channel connector or connecting element. For example, the sealing element or the sealing elements can have one or more O-rings which form the sealing section or sections, the O-rings being held locked on the outside of the immersion tube described or on the inside on the tub connector or channel connector. In another embodiment, the sealing sections can be realized by a common sealing element molded onto the tub connector. For example, the first Sealing section can be realized by a first sealing element molded onto the channel connector and the second sealing section can be realized by a second sealing element molded onto the tub connector. It has proven to be particularly advantageous to provide both sealing sections on a common sealing element and to fix this sealing element to the trough connection before the drainage channel is inserted into the sealing trough and the trough connection is inserted into the trough connection. Only when this is inserted is there a sealing connection between the sealing element via its first sealing section with the channel connector. A connecting element, which can be designed, for example, as the dip tube described, can then be inserted subsequently and connect the two sealing sections in a sealing manner.

In one embodiment, the hard shell section has a horizontally circumferential sealing section, via which the mat section is connected to the hard shell section to form the circumferential sealing line, the hard shell section having a projection section which extends horizontally circumferentially around the sealing section and a horizontally circumferential horizontal end of the hard shell section forms and which is connected to the mat section only via the sealing section. The mat section is thus not directly connected to an area of the projection section, but is only connected indirectly to the projection section via the sealing section. The circumferential sealing line is continuously spaced from the horizontally circumferential end of the hard shell section in this embodiment by at least 1 mm, in particular at least 3 mm, in particular by at least 5 mm, in particular by at least 10 mm. In this particularly advantageous embodiment, the projection section is thus horizontally above the sealing section and thus above the Sealing line before. This enables the mat section to be arranged horizontally within the projection section during transport and assembly of the drainage channel arrangement according to the invention, for example by folding it inwards from the sealing line into the drainage channel which is arranged in the sealing trough. Because the projection section protrudes beyond the sealing line and thus the mat section can be arranged horizontally within the circumferential projection section, the projection section can effectively prevent undesired damage to the mat section. For example, this can prevent a protruding edge of the hard shell section from striking a section of the mat section and damaging it when the interconnected elements of the drainage channel and sealing sleeve fall. It should be generally pointed out that the mat section is preferably designed as a flat membrane. Such a mat section is very well suited for sealing and for connection to another sealed surface, such as a screed or wall provided with a sealing coating. The thin configuration of the mat section is particularly advantageous in order to be connected to such a surface in a manner adapted to the installation environment. However, at the same time, this configuration means that this mat section can be easily damaged, which is why the projection section explained is particularly advantageous. In one embodiment, the hard shell portion has two short ends opposite in the first horizontal direction and two long ends opposite in the second horizontal direction. These ends of the hard shell section are of course formed in the described embodiment by the projection section. The projection section with the short ends particularly preferably projects less horizontally beyond the sealing line than with its long ends, the long ends projecting horizontally in particular at least 3 mm, in particular at least 5 mm, in particular at least 8 mm, in particular at least 10 mm from the sealing line and the short ends in particular projecting horizontally in particular at least 1 mm, in particular at least 3 mm .

In one embodiment, the hard shell section has a step or a groove horizontally between its sealing section and its projecting section. The step or groove is thus provided outside the circumferential sealing line. This step can be particularly advantageous in that material, via which the mat section is connected to the hard shell section, does not produce a bead which can later be disadvantageous for laying tiles on the mat section up to the drainage channel. Such a material can be formed, for example, via a weld seam or via an adhesive connection. In addition, such a step or such a groove can serve to ensure that the projection section ends at a vertical height which is specifically adapted to the vertical height of the drainage channel and indicates a desired height up to which the screed is to be laid around the drainage channel arrangement. In this case, the protruding section of the hard shell section can serve as a peeling edge for the screed layer. At this point it should be generally pointed out that when the drainage channel arrangement according to the invention is installed in a room, the drainage channel is usually set up on a bare floor. For this purpose, feet are particularly preferably provided on the hard shell section, by means of which the hard shell section is set up on the room floor. These feet are particularly preferably adjustable in height, for example by means of corresponding screw connections, so that the vertical height of the upper end of the drainage channels can be matched to the spatial conditions. Such Height-adjustable feet are already known in the case of generic gutter arrangements. However, with these drainage channel arrangements, the feet are provided on the underside of the channel bottom. In the drainage channel arrangement according to the invention, it is provided in a particularly preferred embodiment that the feet are arranged on the underside of the tub floor. On the one hand, this can simplify the assembly of the feet, since mounting sections of the feet can be provided directly in the hard shell section. For example, the hard shell section can be made of a plastic, with the assembly sections of the feet being provided directly in the hard shell section during the manufacturing process. This is not possible with gutters, which are usually made of metal. For example, such a hard shell section can be produced by injection molding. In addition, the connection between the feet and the drainage channel usually represents the risk of a leak. This is because a seal underneath the channel floor must be made around the feet. By providing the feet on the tub floor and the hard shell section, the risk of such a leak is avoided. Because of the knowledge of the invention that the provision of feet on the underside of the, in particular sealing collar of the hard shell section is generally advantageous for generic drainage channel arrangements, the present invention also relates in particular to such a generic drainage channel arrangement in which a sealing device as explained above is not mandatory have to be. Such a drainage channel arrangement has the features described for drainage channels of the generic type and preferably further, with reference to other drainage channel arrangements described in accordance with the invention, feet being fixed in any case on the underside of the sealing sleeve are, in particular are directly connected to this. When installing a drainage channel arrangement according to the invention, the drainage channel with the sealing sleeve is generally first set up on a bare floor, preferably via feet, a drain pan being connected beforehand or subsequently to the tub socket in a sealing manner. A drain pipe is connected to the drain pot. Then screed is applied to the bare floor up to a predetermined target height, which must correspond to the vertical upper edge of the drainage channel. A sealing coating is applied to this screed, which is then connected to the horizontally circumferential end of the sealing sleeve, which is preferably formed over the mat section which is arranged on the hard shell section. The first sealing level explained above is implemented in this way. A floor finish, such as tiles, is then applied to this first sealing level, which then closes with the upper edge of the drainage channel if possible. With this assembly described it is of great importance that the screed ends at the correct height with respect to the upper edge of the gutter. Accordingly, it is particularly advantageous if the hard shell section forms a pull-off edge for the screed layer with its projection section.

In one embodiment, the drainage channel arrangement according to the invention has a construction time protection which comprises a protective cap which, in an assembly position, runs along the second horizontal direction above the sealing sleeve and above the drainage channel and which - at least in sections with respect to the first horizontal direction - extends over both in the Second horizontal direction extends opposite horizontal ends of the gutter. The protective cap particularly preferably extends over at least 50%, in particular over at least 70% of the length of the gutter along the first horizontal direction. In one embodiment, the protective cap is made in one piece, in another embodiment the protective cap is made in several parts, ie comprising a plurality of cap elements. The protective cap is particularly preferably designed in several parts, each of the several cap elements of the protective cap each extending in the mounting position along the second horizontal direction above the sealing collar and above the drainage channel, and at least one, in particular several, in particular all, of the cap elements extends over both in the second horizontal direction extends opposite horizontal ends of the gutter. This can ensure that each of these parts protects a length section, and the multi-part nature of the protective cap ensures that the construction time protection can be used for gutters with different lengths in relation to the first horizontal direction by using protective caps with only partially different cap elements or a protective cap with identical parts is used, wherein depending on the length of the gutter, these different parts assume different positions with respect to one another in relation to the first horizontal direction. In particular, the present invention relates independently of the above-mentioned drainage channel arrangement according to the invention, such a drainage channel arrangement which comprises a drainage channel and a sealing collar, the drainage channel having a horizontally flat channel bottom with an upper and a lower side, a channel connector being arranged on the underside of the channel bottom which extends vertically downward from the channel bottom and which encloses a drain opening provided in the channel bottom on the circumference in a closed manner. The drainage channel is particularly preferably elongated horizontally and has a length in one first horizontal direction, which is at least 5 times, in particular at least 10 times its length in a second horizontal direction. The sealing sleeve forms a sealing trough with a trough bottom, in which the drainage channel lies, the sealing trough having a trough neck, which encloses an opening provided in the trough bottom in a closed manner, within which the trough neck is arranged. Furthermore, this drainage channel arrangement preferably has a drain pot, into which the trough neck opens and which is sealed against the trough neck in a closed manner. This drainage channel arrangement furthermore has a construction time protection comprising a protective cap which runs along the second horizontal direction above the sealing collar and which extends beyond both horizontal ends of the hard shell section which are opposite each other in the second horizontal direction. This drainage channel arrangement according to the invention can have further features which are described in connection with the aforementioned drainage channel arrangements according to the invention and which are described below in connection with a drainage channel arrangement according to the invention. The construction time protection comprising a protective cap enables effective protection of the drainage channel and sealing sleeve during the construction period in each of the drainage channel arrangements according to the invention described, ie during the steps described above when installing a drainage channel arrangement according to the invention in a room.

In one embodiment, the protective cap bears against the hard shell section of the sealing sleeve in the assembly position outside the ends of the drainage channel lying opposite each other in the second horizontal direction. A particularly robust fixation of the protective cap to the hard shell section can be carried out via this concern to be guaranteed. In one embodiment, in the assembly position, the mat section is arranged at least along the second horizontal direction within the extent of the protective cap and is arranged vertically between the drainage channel and the protective cap. In this described embodiment, protection of the mat section is ensured particularly effectively in the mounting position. In particular, the hard shell section can have the above-described projection section. In general, it should be pointed out at this point that the drainage channel arrangement naturally consists of several components, depending on the selected position, ie first operating position, second operating position and mounting position, these components are aligned with one another in a specific arrangement.

In one embodiment, the protective cap has a protective cap opening which is aligned with the drain opening in the mounting position. The protective cap opening particularly preferably has such a clear cross section that corresponds at least to the clear cross section of the drain opening in the mounting position, with the protective cap being particularly preferably fixable in the mounting position via an immersion tube on the drain gutter, which is arranged in the mounting position within the gutter socket and both is non-positively or positively on the gutter socket as well as on the protective cap.

in principle representations, cross sections of various drainage channel arrangements according to the invention.

In the Figures 1 to 5 is based on one and the same embodiment of a drainage channel arrangement according to the invention. In Figure 6 this embodiment is shown with two different lengths. This gutter arrangement comprises a gutter 1, which has a length in a first horizontal direction X, which is more than 5 times its length in a second horizontal direction, which is perpendicular to the first horizontal direction X. In Figure 1 comprehensively the Figures 1a and 1b the drainage channel arrangement is shown with a cross section which runs along the first horizontal direction X and perpendicular to the second horizontal direction. Figure 1b shows an enlarged detail view a section Figure 1a .

In Figure 1 the drainage channel arrangement is shown integrated in a room floor. The room floor comprises an unfinished floor 6 on which screed 7 is applied. Above the screed 7 runs the first sealing level, on which tile adhesive 8 and tiles 9 are laid. The tiles 9 are flush with their upper edge to the upper edge of the gutter 1 and are connected to the gutter 1 by a silicone seal 10.

In the Figure 1 The drainage channel arrangement shown has a sealing collar 2 which has a hard shell section 20 which forms a sealing trough with a trough bottom 21 and a trough connection 22. The sealing collar 2 also has a mat section 23 which extends horizontally circumferentially around the hard shell section 20 and which is connected to the hard shell section 20 in a sealing manner within its sealing section 201 by means of a closed circumferential sealing line. In the area of the sealing line, the mat section 23 overlaps with the hard shell section 20. The drainage channel 1 is located in the sealing trough formed by the hard shell section 20. The channel bottom 11 runs essentially parallel to the trough bottom 21 and lies within the vertical extent of the trough walls of the sealing trough. The gutter 1 has a gutter neck 12 which lies radially inside the tub neck 22. The gutter neck 12 encloses a drain opening, which is flush with the opening in the tub base 21, which is enclosed by the tub neck 22, which is closed and circumferentially closed.

The trough connection 22 is sealed in a circumferentially closed manner with respect to a drain pot 4, which is arranged on the sealing collar 2 and drain gutter 1 in such a way that the drain opening and opening open into the drain pot 4. At the drain pot 4, a drain pipe 5 is connected to it is designed to lead waste water, which is discharged from the gutter 1 into the drain pot 4, into the sewage system.

In the Figure 1 Drainage channel arrangement shown also has feet which are arranged and fixed on the underside of the sealing trough formed by the hard shell section 20 of the sealing sleeve 2. The entire drainage channel arrangement is set up on the unfinished floor 6 via these feet. When installing the drainage channel arrangement according to Figure 1 the drainage channel arrangement is first placed over the feet on the raw floor 6, then the drain pan 4 is connected to the drain pipe 5, then screed 7 is applied, then the top of the screed is provided with a sealing coat, and then the mat section 23 is sealed with the sealing coat in a watertight sealing manner, then tile adhesive 8 and tiles 9 applied and then the tiles 9 connected to the drainage channel 1 via a silicone seal 10. Details of this assembly are given below with reference to the Figures 2 and 3rd explained in more detail.

Out Figure 1 it can also be seen that the described embodiment comprises a sealing device which has an immersion tube 300, a first sealing section 100 and a second sealing section 200. The first sealing section 100 is formed by a first sealing element, the second sealing section 200 is formed by a second sealing element. Both sealing elements lie on the outside of the connecting section formed by the immersion tube 300. The first sealing section 100 also bears on the inside of the channel connector 12, the second sealing section 200 on the inside of the tub connector 22. Correspondingly, the sealing device in FIG Figure 1 shown operating position between the tub connector 22 and the channel connector 12 a watertight sealed collection volume provided. The Collection volume has, at least in sections, a shape in the manner of a cylinder with an annular base, which is generally advantageous according to the invention.

In Figure 2 comprehensively the Figures 2a and 2b is the drainage channel arrangement according to the invention Figure 1 shown in their mounting position. Figure 2b shows an enlarged detail view of the representation according to Figure 2a . Also in the representations according to Figure 2 the gutter arrangement is shown with a cross section perpendicular to the second horizontal direction. The drainage channel arrangement comprises construction time protection with a protective cap, which has a central element 50 and end elements 51, 52 as cap elements. The center element 50 has a protective cap opening, which is surrounded in a closed manner around a protective cap socket 500, which engages in the gutter socket 12 in the assembly position and is arranged within this gutter socket 12. In this mounting position, the central element 50 is held on the drainage channel 1 via its protective cap socket 500, and the end elements 51, 52 are connected via a in Figure 2 Positive connection, not shown, on the hard shell section 20, in the present case fixed on the projection section 202 of the hard shell section 20. How from Figure 2 The hard shell section 20 can be seen particularly clearly on a horizontally circumferential sealing section 201, via which it is sealingly connected to the mat section 23. The hard shell section 20 furthermore has a projection section 202 which extends horizontally circumferentially around the sealing section 201 and which thus projects horizontally circumferentially beyond the sealing section 201. In the in Figure 2 In the illustrated installation position of the drainage channel arrangement, the mat section 23 is folded inwards starting from the sealing line via which it is connected to the sealing section 201, so that the projection section 202 protrudes horizontally over the mat section 23 and the mat section 23 is arranged within the horizontal extent of the end caps 51, 52. Therefore, the mat section 23 is particularly well protected from damage in the assembly position shown.

In Figure 3 is the drainage channel arrangement according to the invention Figure 2 shown during assembly in a room floor after the screed 7 has been applied to the raw floor 6. Starting from the in Figure 2 illustrated assembly situation, a screed 7 was thus applied, which is essentially flush with the top of the hard shell section 20. Furthermore, the protective cap comprising the center cap 50 and end caps 51, 52 was removed, and a sealing coat was applied to the screed 7. In a subsequent assembly step, the mat section 23 can then be unfolded and placed on the screed 7 and glued in a watertight, sealing manner to the sealing coating which was previously applied to the screed 7. In a subsequent assembly step, the first sealing level of tile adhesive 8 and tiles 9 provided by the sealing sleeve 2 and the sealing coat on the screed 7 is laid, after which a mounting situation as in FIG Figure 1 can be produced shown.

In Figure 4 a drainage channel arrangement according to the invention is shown in a detailed view after it has been integrated in a room floor. This representation corresponds to the representation according to Figure 1 with the difference that it is shown that the silicone seal 10, which connects an adjacent tile 9 to the gutter 1, is defective. Correspondingly, when the drainage channel arrangement according to the invention is used as intended, in which water is collected in the drainage channel 1 and discharged via the drain pan 4 into a drain pipe 5, the defective one Get silicone seal 10 between the sealing trough and drainage channel 1. In this case, the water builds up in the collecting volume between channel connector 12 and trough connector 22, but cannot get into the drain pot 4 because of the sealing connection between the first sealing section 100, the second sealing section 200 and the immersion tube 300 forming the connecting section. The sealing device described also ensures at the same time that, in the event of a backflow of water, no water can get into the collecting volume from the drain pot 4. At the in Figure 4 described state, it is necessary that leachate, which has collected between drain channel 1 and sealing trough, is deliberately released so that it can also flow into the drain pan 4 and from there into the drain pipe 5. This is realized in the second operating position of the drainage channel arrangement, which in Figure 5 is shown.

In the in Figure 5 The illustrated second operating position of the drainage channel arrangement according to the invention, the immersion tube 300 and thus the connecting section is removed from the sealing sections 100, 200. Correspondingly, a passage opening 70 is formed between the sealing sections 100, 200, through which the leachate, which has collected in the collecting volume described, can run off into the drain pan 4. When the dip tube 300 is reinserted, however, the first operating position is again as in FIG Figure 4 shown restored so that in this first operating position the drainage channel arrangement can again be used as intended for the removal of considerable amounts of water without these amounts of water being able to get into the intermediate area between the two sealing levels described.

In Figure 6 comprehensively the Figures 6a and 6b is the principle the protective cap or the construction time protection of the drainage channel arrangement according to the invention described. In Figure 6 a cross section perpendicular to the second horizontal direction is shown. Out Figure 6 comprehensively the Figures 6a and 6b it can be seen that the protective cap comprises a central element 50 as well as a first end element 51 and a second end element 52. First end element 51 and center element 50 overlap in a first overlap section, while second end element 52 and center element 50 overlap horizontally in a second overlap section. Such an overlap is made possible because the end elements 51, 52, which are identical to one another, have a greater extent along the second horizontal direction than the center element 50 and because these end elements 51, 52 run above the center element 50. Out Figure 6 it can be seen that this construction of the protective cap enables the protective cap comprising central element 50 and end elements 51, 52 to be used for gutters 1 with different lengths along the first horizontal direction X, since then depending on the length of the gutter 1, the length of the overlap section along the first horizontal direction X, over which the respective end elements 51, 52 extend along or overlap with the central element 50. So with a shorter one, in Figure 6a schematically illustrated embodiment, the overlap sections shorter than in a longer, in Figure 6b schematically illustrated embodiment. The mat section 23 is always closed by the protective cap Figure 2 explained protected. Accordingly, the provision of a protective cap comprising center element 50 and end elements 51, 52, which are of identical design, enables a very cost-effective implementation of a protective cap, since a protective cap can be provided with very few components, which can be used for gutters 1 with different lengths can be used along the first horizontal direction X and always enables reliable protection of the mat section 23.
