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.
  • the diffusion openings 17, 18 therefore form an integral part of the gutter element 10.
  • 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.
  • the structure of the diffusion openings 17, 18 is in the Figures 3, 4 shown in detail.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • This possibility of secondary drainage is provided in addition to the diffusion openings 17, 18.
  • the underside of the frame flange 13 is profiled by the point connections that firmly connect the gutter element 10 and the frame 12.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the drainage channel is made of electropolished stainless steel.
  • the drain pot 22 is welded to the gutter element 10.
  • 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.
  • the drainage channel has a height adjustment 24.
