Description

The invention relates to a drainage channel for sanitary areas and / or terrace areas with the features of the preamble of claim 1. Such drainage channels are known in practice and available on the market. The invention further relates to a method for the production and a method for installing such a drainage channel.

Known drainage channels for showers usually have a channel element with at least one outlet. The process is used for primary drainage. Primary drainage is understood to mean the drainage of wastewater, which occurs, for example, when showering. The known drainage channel further comprises a frame with a frame flange, which is connected to the installation with floor tiles. The channel element and the frame are separate components that are inserted into each other when installing the drainage channel. In this case, the channel element is dimensioned such that a circumferential gap arises between the channel element and the frame, which is fluid-connected to the outlet of the channel element. This gap is arranged so that a second drainage level for the secondary drainage is formed.

Secondary drainage is known in connection with open-pored floor coverings, for example in parking garages or on terraces, through which water can flow. In the context of drainage channels for sanitary areas, this term is also used, which, in contrast to open-pored floor coverings, does not lead to a water flow under the tiles, but rather to a diffusion of water. If, for example, damaged tiles or floor coverings penetrate water into the floor, the floor covering can become saturated with water or water or moisture can accumulate under the floor. The secondary drainage allows the drying of damp floor coverings or floor tiles.

Known drainage channels with secondary drainage are difficult to clean. Webs, dirt joints and installations (for example for height adjustment of the grates) prevent easy care. Especially the circumferential cavities between the frame and gutter can not be cleaned easily, because they are not accessible. Therefore, cleaning utensils (e.g., small brushes) are often included. The cleaning is cumbersome and expensive.

The invention is based on the object to improve the drainage channel of the type mentioned in that the drainage channel on the one hand allows the secondary drainage and on the other hand is relatively easy and quick to clean. The invention is further based on the object of specifying a method for producing such a channel and a method for installing such a channel.

According to the invention this object is achieved by a drainage channel having the features of claim 1. Specifically, the object is achieved by a drainage channel for sanitary areas, in particular for showers, and / or for patio areas with a gutter element that has at least one drain for a primary drainage. The drainage channel comprises a frame having a frame flange for connection to tiles, and a device for secondary drainage. The channel element and the frame are firmly connected. The device for the secondary drainage is integrated in the channel element and / or in 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. For this purpose, it is provided that the gutter element and the frame on the one hand firmly connected and on the other hand, the device for the secondary drainage forms an integral part of the gutter element and / or the frame. In this case, the device for secondary drainage can be integrated either only in the channel element or only in the frame or in each case in the channel element and in the frame.

In contrast to the prior art, therefore, the device for the 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. The device for the secondary drainage is rather integrated into the channel element as such and / or in the frame as such. As a result, these components are decoupled with respect to the secondary drainage, so that the channel element can be optimized with a view to ease of cleaning. The integrated secondary drainage allows rapid drying of the soil even with natural stone coverings.

The fixed 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.

Under a solid connection between the channel element and the frame is understood a connection that can not be solved without destroying. The drainage channel can be understood as a one-piece installation element, which is uniformly handled as a whole.

Secondary drainage means that water that can penetrate under the floor covering or under the floor tiles, for example because of damaged joints, can diffuse into the drainage channel, in particular the channel element. Primary drainage means the drainage of the wastewater accumulating, for example, when showering or generally during bath drainage.

Preferred embodiments of the invention are specified in the subclaims.

Preferably, the channel member has a gutter flange which is fixedly connected to the frame flange of the frame. The gutter flange and the frame flange can be placed plane-parallel to each other in the production of the drainage channel and firmly connected. This creates a secure and tight connection between the channel element and the frame.

The gutter flange and the frame flange preferably form flat surfaces that extend outwardly substantially perpendicularly from the gutter element. In the installed state, the channel flange and the frame flange are arranged at least partially substantially horizontally. The frame flange can be folded up on the wall side.

The gutter flange is arranged in a preferred embodiment in a recess on the upper side of the frame flange. This has the advantage that the gutter flange in the frame flange can be completely submerged, so that the frame flange forms a consistently flat surface, which can be connected to floor tiles or other floor coverings.

Preferably, the channel element and the frame, in particular the channel 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 sufficient for sufficient strength.

In a particularly preferred embodiment, the point connections include clinch joints. In contrast to riveted joints, clinching joints have the advantage that the material to be joined is only reshaped and thus the tightness is maintained. In addition, clinching joints offer good strength values sufficient for the application of the drainage channel in the sanitary sector.

By clinching connections are compounds that connect flat metallic components, in particular sheets without using a filler material. Specifically, the inventive Drainage channel preferably made of metal, more preferably made of steel, especially stainless steel. The joint connection is made by forming the components to be joined, whereby a positive and non-positive connection is achieved. The throughput joining is also known under the terms pressure joining, clinching, press joining or toxing.

The device for the secondary drainage may preferably have a profiling on the underside of the frame, in particular on the underside of the frame flange. In this case, for example, have the underside of the frame or the frame flange having an outwardly projecting profile in the form of local spacers. The spacers are in the installed state on the ground 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, can diffuse through the moisture or water that has penetrated under the floor tiles or under the floor covering.

In this embodiment, the device for the secondary drainage is integrated into the frame or in the frame flange.

In a particularly preferred embodiment, the profiling is formed by deformed portions of the frame, in particular of the frame flange in the region of the clinching joints. The clinch joints result in bulges on the underside of the frame, particularly the frame flange, which act as spacers.

The clinch joints thus have a dual function. On the one hand, these allow the firm connection between the channel element and the frame. On the other hand, the clinching joints on the underside of the frame or the frame flange form the profile responsible for the secondary drainage in the form of local bulge, which arise during forming.

In a further preferred embodiment, the device for the secondary drainage on diffusion openings, which in the channel element are formed. The diffusion openings and thus the device for secondary drainage form an integral part of the channel element.

The diffusion openings may additionally or alternatively be provided for profiling the underside of the frame flange.

The diffusion openings have the advantage that water which has penetrated under the floor tiles or floor coverings can diffuse out and can escape through the diffusion openings. This promotes the drying of the soil. It has been found that several discrete diffusion openings are sufficient to achieve sufficient drying. It is not absolutely necessary that a continuous gap is formed, which 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 enough from 4 to 10 diffusion openings per gutter side. Another number of drainage holes is possible.

In this case, first can be formed in diffusion openings in the channel flange and / or second diffusion openings in a side wall of the channel element. In a particularly preferred embodiment, the first diffusion openings in the channel flange pass respectively into associated second diffusion openings in the side wall of the channel element and form channels which open into the channel element. As a result, a good fluid connection between the bottom of the floor tiles or the floor covering and the gutter element is formed, so that the moisture contained in the floor tiles or floor covering can dry well.

Preferably, a sealing collar is connected to the frame flange. Particularly preferably, the sealing collar is flexible in different directions in different directions. This has the advantage that the sealing collar can be flexibly adjusted in the direction in which the largest gutter work acts to minimize joint cracks. Therefore, it is particularly preferred if the sealing collar is more flexible in a direction transverse to the longitudinal axis of the channel element than in a direction parallel to the longitudinal axis of the channel element.

In a further preferred embodiment, the surface of the channel element is electropolished. As a result, a long gloss resistance and low dirt adhesions of the gutter element is achieved.

Preferably, a drain pot is welded to the gutter element. This enables a full-fledged steel gutter, especially a stainless steel gutter, which can be installed quickly and safely and meets the highest standards of design and care. The fully welded drain pot or drain protects the floor structure permanently against penetrating water.

With regard to the manufacturing method, the object is achieved by a method for producing a drainage channel according to the invention, are introduced in the diffusion openings for a secondary drainage in a channel element having at least one drain for a primary drainage. The gutter element is firmly connected to a frame by clinching. The advantages described above in connection with the diffusion openings and the fixed connection between the frame and the channel element will be referred to here.

With regard to the installation method, the object is achieved by a method for installing a drainage channel according to the invention, in which a liquid seal is either applied at a distance before the device for secondary drainage such that the device for secondary drainage is opened in the installed state. Alternatively, the liquid seal is applied such that the secondary drainage means is covered and closed. This relates primarily to the diffusion openings, which can be activated or deactivated in this way, depending on whether secondary drainage is desired or not.

The invention will be described in more detail below with reference to the attached figures with reference to embodiments with further details.

The drainage channel shown in the figures is used for drainage in sanitary areas and / or patio areas. The drainage channel is installed in tiled floors or in floors with natural stone coverings, where secondary drainage may be important in addition to primary drainage. The drainage channel is designed primarily for showers and can be called a shower channel. Other applications in the sanitary sector are conceivable.

The drainage channel has a channel element 10 with a substantially rectangular shape. In the bottom of the channel element 10, a drain 11 is formed. The bottom is inclined in a conventional manner, so that the drain 11 is located at the lowest point of the gutter element. It is possible to provide more than one drain 11, especially with longer drainage channel.

Through the process 11, the primary drainage takes place.

The channel member 10 has side walls 19 which extend substantially perpendicular to the bottom of the channel member 10 and, as in Figs FIGS. 1, 2 to recognize well, to form a supernatant. The supernatant corresponds essentially to the connection height of the floor tiles or the floor covering. The Side walls 19 are each connected to a channel flange 15, in particular integrally connected, which extends perpendicular to the side walls 19 to the outside.

The channel element 10 is arranged in or on a frame 12, which has a frame flange 13, and firmly connected thereto. The frame flange 13 extends perpendicular to the side walls 19 of the channel element 10. When installed, the frame flange 13 and the channel flange 15 are arranged horizontally.

As in FIGS. 1, 2 To recognize the channel element 10 has a device for the secondary drainage 14. The device for the secondary drainage 14 serves to allow the diffusion of moisture or water, which has accumulated below or in the floor tiles or in the floor covering, for example, due to damaged tile joints.

The secondary drainage device 14 is in the form of diffusion openings 17, 18. The diffusion openings 17, 18 are located in the channel element 10, specifically in the channel flange 15 and in the side walls 19 of the channel element 10. The diffusion openings 17, 18 thus form an integral part of the channel element 10.

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.

The structure of the diffusion openings 17, 18 is in the FIGS. 3, 4 shown in detail.

As in Fig. 3 can be seen, a first diffusion openings 17 is formed in the channel flange 15. The first diffusion openings 17 form an elongate opening through the channel flange 15, which extends down through the top of the frame flange 13 is limited. The first diffusion openings 17 extend substantially perpendicular to the longitudinal axis of the channel element 10.

As in Fig. 4 To recognize, a second diffusion openings 18 in the side wall 19 of the channel element is formed. The first diffusion openings 17 in the channel flange 15 merge into the second diffusion openings 18 in the side wall 19, thus forming a channel 20 which connects the outside of the channel element with the inside thereof. As in Fig. 3 The channel 20 is an elongated slot which extends substantially perpendicularly to the longitudinal direction of the channel element 10 in the region of the longer side. As in Fig. 1 To recognize well, several similar channels 20 are formed per longitudinal side of the gutter element, each extending parallel to each other and transverse to the longitudinal axis of the gutter element 10. The individual channels 20 are each formed correspondingly, thus have first and second diffusion openings 17, 18, as described above on.

The function of the diffusion openings 17, 18 is to diffuse the accumulated under or in the floor tiles or flooring or moisture accumulated water to the outside into the environment. For this purpose, the channels 20 are formed in the channel flange 15 so that they partially overlap with the floor tiles immediately adjacent to the drainage channel. 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.

In addition or as an alternative to the diffusion openings 17, 18, the drainage channel on the underside of the frame 12 or of the frame flange 13 may have secondary drainage devices 14, which are not shown in the figures. The device for secondary drainage 14 on the underside of the frame 12 and the frame flange 13 may be formed as a point profiling that protrude beyond the bottom of the frame. This profiling forms a plurality of spacers which stand up on a base and form a cavity between the base and the bottom of the flange 13, through which liquid or water can diffuse outwards. In the starting example according to FIGS. 1 to 6 is this possibility of secondary drainage in addition to the diffusion openings 17, 18 is provided.

The profiling of the underside of the frame flange 13 is effected by the point connections which connect the channel element 10 and the frame 12 firmly.

For this purpose, the gutter flange 15 of the gutter element 10 is arranged in a corresponding recess 16 on the upper side of the frame flange 13 plane-parallel to the frame flange 13. In Fig. 4 can be seen, the depth of the recess 16 is slightly larger than the height of the Rinnenflansches 15, so that the Rinnenflansch 15 is completely received in the recess 16. It is sufficient if the channel flange 15 is flush with the top of the frame flange 13. It is only important that a flat top of the frame flange is formed on the plane-parallel, the floor tiles can be arranged.

The point connections between the channel element 10 and the frame 12 are made by clinching. In this case, a push-button-like, positive connection between the channel flange 15 and the frame flange 15 is produced in a cold forming process.

A clinching tool, as is known, consists of a punch and a die. The parts to be joined are pressed by the stamp similar to the deep drawing under plastic deformation in the die. The shape of the die creates a snap-like connection, which connects the parts with each other in a positive and non-positive manner.

The push button-like contour of the connection protrudes on the underside of the frame flange 13 and forms a profiling. The profiling serves as a spacer when the frame flange 13 is placed on a base during installation of the drainage channel. By the spacers, a small gap or cavity is formed between the base and the frame flange 13, through which the moisture can diffuse. The profiling thus forms a device for secondary drainage 14, which is integrally formed in the frame flange 13.

In Fig. 3 It is good to see that the integration of the secondary drainage means 14 into the gutter member 10 results in the inner wall of the gutter member 10 being substantially free of undercuts. Since the gutter element 10 is also built-in the rest, this can be easily cleaned with a cloth, without the need for special cleaning utensils are required.

As in Fig. 5 shown, the frame flange 13 is connected to a sealing collar 21. The sealing sleeve 21 is highly tear-resistant and expansible. Specifically, the expansion direction of the gasket is isotropic. The sealing collar can be stretched further in a direction transverse to the longitudinal axis of the channel element 10 than in an erection parallel to the longitudinal axis of the channel element.

The drainage channel is made of electropolished stainless steel. The drain pot 22 is welded to the channel element 10.

When installing the drainage channel there are various possibilities. If secondary drainage is desired, then a liquid seal (not shown) may be applied so that the diffusion openings 17, 18 remain free. In the 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.

If no secondary drainage is desired, then a seal, for example as in Fig. 6 shown inserted into the throat between the channel flange 15 under side wall 19, which closes the diffusion openings 17, 18. It is also possible to apply the liquid seal to the side wall 19 so that the diffusion openings 17, 18 are thereby also closed. Secondary drainage is thus largely deactivated.

The present invention is illustrated and explained with reference to horizontal frame flanges. It is also possible aufkannten a near-wall mounting a frame flange. The diffusion openings 17, 18 function in the prescribed manner.

As in FIGS. 5, 6 shown, the drainage channel on a height adjustment 24.
