Definitions

  • the invention relates to a drain fitting with a drain housing.
  • the invention also relates to a shower arrangement equipped therewith.
  • the invention is based on a customary and widespread design of a drain fitting, as it is, for example, from the EP 2 157 247 B1 ( Fig. 1 ) and the EP 2 478 812 A1 is known.
  • the drain housing and the drain seal are arranged on the underside of a shower element in the form of a shower tray at a drain opening and then braced against the underside of the shower tray by the clamping ring arranged from above on the shower tray in the area of the drain opening, for which simple screws are provided.
  • the drain seal With the drain seal, a seal against the leakage of water is achieved despite the necessary divisibility of the drain fitting.
  • shower elements such as shower trays must also be installed in a watertight manner in building structures, for which purpose sealing tapes and prefabricated sealing corners are arranged on an edge of the shower tray and connected to adjacent floor and wall surfaces in a watertight manner.
  • a corresponding sealing arrangement for sealing an edge area of a sanitary tub is from EP 1 038 485 A2 famous. Such an edge-side seal is independent of the previously described seal on the drain fitting.
  • drain housing designed as a pot having a wide molded collar.
  • a sealing membrane can be glued or welded to the wide collar, which increases the dimensions of the drain fitting considerably and is complex to manufacture.
  • the invention is based on the object of specifying a drain fitting which is easy to handle and, in combination with a sanitary facility in a building structure, enables particularly simple, reliable sealing.
  • a flat sealing strip section extending away from the drain housing adjoins the drain seal in a materially bonded manner.
  • this enables a seal provided within the drain fitting to be converted directly into a flat seal.
  • a continuous, uninterrupted seal can thus be achieved starting from a conventional drain fitting. It can so on
  • a reliable integral sealing plane can be formed in a particularly simple manner, which is also completely or largely prepared with regard to the subsequent assembly of a shower element or another sanitary facility, such as a bathtub.
  • drain body With regard to the shape of the drain body, no adaptations are necessary within the scope of the invention compared to configurations according to the prior art, so that known and already available drain bodies can be used without further ado.
  • the drainage seal having the elastomeric ring body and the sealing web section are formed in one piece from a uniform elastomer material.
  • the annular body which has a cross section of a conventional drainage seal, can then be formed together with the sealing strip section in a primary molding process.
  • thermoplastic elastomers and thermosetting elastomers come into consideration, the drainage seal with the sealing strip section formed thereon being produced together in a uniform primary molding process.
  • the sealing sheet section is injection molded onto the drainage seal.
  • Such injection molding can take place with two materials in a single work step, the materials then having to be fed in differently.
  • An injection however, the same material or two different materials can also be used in two steps.
  • the sealing strip section it is possible first of all to form and / or cut a sheet material for the sealing strip section and to form an opening there where the drainage seal is subsequently to be injected on.
  • the sealing strip section provided with the opening can then easily be inserted into an injection mold for the drainage seal.
  • the sealing sheet section is glued or welded to the drainage seal.
  • Gluing is understood to mean a connection in which an additional material in the form of an adhesive is provided. Such gluing can of course also be supported by an input of heat.
  • hot melt adhesives hardening two-component adhesives or permanently tacky adhesives such as butyl adhesives can be used.
  • the adhesive can be arranged as an intermediate layer directly between the drainage seal and the sealing sheet section, for which purpose these are then to be arranged in an overlap.
  • the adhesive can, however, also be applied from the outside to a separate adhesive carrier in the manner of an adhesive tape, in which case the sealing sheet section and the drainage seal can either be arranged in an overlap or just next to one another.
  • welding is possible and expedient in particular when the drainage seal and the sealing sheet section are at least partially formed from thermoplastic material. Welding can be achieved Heat input takes place by means of hot air, infrared radiation or the like. In addition, ultrasonic welding is also particularly suitable for achieving a particularly reliable and intimate connection.
  • connection that is to say in particular different types of gluing and / or welding, can also be combined with one another.
  • the drainage seal can have a collar that runs radially around the ring body and is preferably planar or substantially planar on its underside and top, to which the sealing strip section then adjoins.
  • sealing strip section and the drainage seal together form a pre-produced, coherent module.
  • the material connection then takes place before assembly, in particular at the factory in a manufacturing company.
  • the invention is not restricted to this.
  • the ring body can also have a shape deviating from a circle in the plan view, for example oval or rectangular.
  • the term radially is to be understood in the sense of extending outward.
  • the sealing sheet section can be formed, for example, from a single-layer or multi-layer film or also a waterproof laminate.
  • the laminate can, for example, have a reinforcement in the plastic material or as a separate layer, a fleece, a lattice or the like.
  • the sealing strip section can have a compensation area, for example, by means of a wave or fold shape running around the drain fitting.
  • the sealing sheet section can also be slightly elastic and / or plastically stretchable without losing its sealing properties. In the case of a plastic web, slight stretchability can also be achieved, for example, by foaming the plastic material with a closed structure of the foamed cells.
  • the compensation area provides a separate function and can optionally also be manufactured separately from a further material as a central functional area.
  • the drain seal and / or the sealing sheet section is / are preferably provided and designed to bridge a free space around the drain housing in a self-supporting manner.
  • the compensation area explained above can be arranged in this free space, so that spatial adaptation is then possible there through the free space.
  • the free space can extend, for example, over a length between 0.5 cm and 20 cm, in particular between 1 cm and 10 cm.
  • Sealing surface can be achieved. It is useful if the elastomeric ring body is already held in the radial direction before it is fixed by the clamping ring on the drain housing, for which purpose, for example, a form fit in the radial direction can be provided. Such a form fit is possible both in a rotationally symmetrical manner with a circumferential groove or rib or also by means of individual centering projections or the like.
  • the elastomeric ring body and the drain housing can have mutually complementary form-fitting contours with at least one projection and at least one recess receiving the projection.
  • Such interlocking projections or ribs the elastomeric ring body can then be prepositioned and protected against slipping even before the clamping ring is assembled.
  • Such form-fit contours can be provided around the circumference or only in sections in the circumferential direction, which is sufficient for prepositioning. In the case of ring-shaped, circumferential contours, there is the advantage that it can be placed in any angular orientation.
  • the elastomeric ring body can also encompass a web of the drain housing in a C-shape, so that the ring body is then well secured against inadvertent loosening even before final assembly.
  • the elastomeric ring body and the sealing strip section adjoining it in a materially bonded manner are preferably already connected to one another at the factory, if both are not made of a uniform, continuous material anyway manufactured or already formed in the case of different materials by a 2-component injection molding that is inseparably connected to one another.
  • the unit formed by the elastomeric ring body and the sealing strip section can either already be arranged on the drain housing and, if necessary, be fixed or prefixed, or else be enclosed separately.
  • the sealing strip section extends away from the drain housing and can ultimately also form a large-area sealing layer. At least the sealing membrane section should be selected to be large enough that it can easily be integrated into a continuous, flat seal, as was also described above in connection with the shower area substructure.
  • the sealing sheet section preferably covers an area of at least 0.04 m 2 and in particular at least 0.09 m 2 with respect to its outer circumference. If, for example, the sealing strip section has a square shape on its outer circumference with an edge length of 30 cm, this size is then sufficient to create a connection to adjacent sealing material, a sealing paint or the like at a distance from the drain housing itself.
  • the size of the sealing sheet section can also be selected to be larger, depending on the respective requirements. It is therefore also possible in principle that the sealing sheet section is already so large that the entire surface to be sealed is covered. Further sealing material is then not necessary, although the handling of the sealing strip section can be unwieldy and, if necessary, the sealing strip section also has to be cut to size (eg edge trimming and / or incisions).
  • the invention also relates to a shower arrangement of the above-described drain fitting and with a shower element having a drain opening, the drain housing and the drain seal being arranged on an underside of the shower element with the clamping ring arranged on an upper side of the shower element being braced against the shower element through the drain opening , wherein a sealing layer is formed below the shower element, integrating the sealing sheet section.
  • a shower area substructure with a carrier plate having a recess for a water drain for receiving a shower element and a plurality of height-adjustable feet on an underside of the carrier plate can be formed within the scope of the invention.
  • the recess is usually larger than the drain body of the drain fitting, so that during assembly the drain body can be inserted into the recess with air, i.e. all around with a free space. If necessary, the free space can also compensate for a certain misalignment.
  • the sealing layer is preferably provided and set up to bridge the free space around the drain housing in a self-supporting manner.
  • the free space can extend, for example, over a length between 0.5 cm and 20 cm, in particular between 1 cm and 10 cm.
  • a sealing layer is placed directly on an upper side of the carrier plate is arranged, wherein the waterproofing layer is connected to adjacent building surfaces in a watertight manner.
  • the sealing layer can in particular be formed in a known manner by a sealing membrane, in particular sealing foil, and / or a sealing paint including spreadable, in particular cement-containing systems.
  • the sealing layer can also have different areas, some of which can be formed by a sealing membrane, in particular sealing film, and partly by sealing paints, waterproof adhesives or the like.
  • prefabricated sealing corners can also be provided as components.
  • Sealing materials such as sealing sheets and in particular sealing sheets can also have self-adhesive properties through a corresponding coating and / or the selection of a sticky layer material, in which case corresponding surfaces can also be covered by a release paper, a release film or the like before processing.
  • butyl plastics in the form of tapes or sheets can be used, which have good adhesive or self-adhesive properties.
  • IVD Leaflet No. 5, November 2014 edition Sealing with butyl tapes - properties, processing, areas of application" as an example.
  • the person skilled in the art is also familiar with other sealing materials which have adhesive properties and in particular are provided with a separate adhesive.
  • the sealing layer as a watertight, closed unit can only be produced or assembled directly on the carrier plate during assembly. For example, it is possible to form the entire sealing layer uniformly from one sealing paint. As previously explained you can Sealing membranes, sealing tapes, sealing corners and comparable components are combined to form the watertight sealing layer and, in particular, are connected to one another. Such a connection of several components can expediently also take place directly on the carrier plate. However, if the dimensions to be observed for the installation of the shower element, such as distances and heights, are known in advance, an already three-dimensional sealing layer can be prepared from several components or possibly in one piece, so that such a prefabricated sealing layer is then only placed on the carrier plate during installation or must be applied. Expansion areas can then also be provided at suitable points for any remaining dimensional adjustments.
  • the sealing takes place in an intermediate level on the one hand above the actual floor or subsurface on which the height-adjustable feet are supported. At the same time, the seal takes place independently or at least largely independently of the shower element itself.
  • a type of receiving tub is thus formed separately from the shower element, which can in particular be configured as a shower tray, which ensures a complete liquid seal.
  • the sealing layer is formed on the upper side of the carrier plate, which is flat or at least essentially flat.
  • a sealing layer can therefore be laid on particularly easily as a prefabricated sheet or applied as a spreadable material. This reduces the risk of assembly errors.
  • the gradient necessary for the water flow is usually only provided for the shower element itself to be arranged above it.
  • Another advantage is that a cavity remains under the carrier plate between the height-adjustable feet, which is permanently and reliably sealed at the top. This free space can thus easily be used safely for installation purposes. Without violating the strict regulations for sealing in the sanitary area, various house installation lines can then also be laid below the carrier plate. This can be power lines, fresh water lines, sewage lines, heating pipes or the like, for example.
  • the shower space substructure prevents damage to the adjacent building structure in a particularly safe and reliable manner.
  • the shower element to be placed can of course also be tightly connected to adjacent surfaces. Complete sealing is possible, but not absolutely necessary within the scope of the invention, because the sealing layer, which ensures the actual protection, is formed on the upper side of the carrier plate.
  • the shower element is installed particularly easily after the desired height has already been achieved by positioning the carrier plate by means of the height-adjustable feet is provided. It is often sufficient for the shower element to be inserted from above and, if necessary, to be protected against slipping on the circumference. Such a fixation results directly from an installation flush with the floor and a circumferential maintenance expansion joint, for example a silicone joint.
  • the shower element is then to be connected to the drain, for which purpose the drain fitting according to the invention is provided.
  • the installation of the shower element is then particularly simple and, if necessary, can even be done by laypeople, because the building-safe seal is then already in place and completely completed.
  • the shower element can thus also be easily removed again without the building-safe seal being impaired.
  • the shower element can easily be replaced, with water that has accumulated on the sealing layer in the event of a leak in the shower element, even after removal, if loosening the drain fitting is not sufficient.
  • the tightness can also be checked immediately after the described easy removal of the shower element. If, contrary to expectations, there are leaks, these can also be easily repaired before the same shower element or another shower element is reinstalled.
  • the carrier plate can be flat or essentially flat on its upper side and preferably also on its lower side.
  • the carrier plate must have sufficient stability and strength in order to be able to carry the shower element and to be able to support it downwards.
  • composite materials and structural chamber panels come into consideration, such as those sold by Interplast Kunststoffe GmbH under the name Triplex®.
  • carrier plates made of a wood material are also particularly suitable.
  • laminated veneer lumber comes into consideration due to its high stability.
  • the laminated veneer lumber can be compacted and particularly preferably impregnated with synthetic resin.
  • Corresponding panels are also referred to as synthetic resin pressed laminated wood, the individual veneer layers preferably being arranged at an angle to one another to increase stability in order to form plywood or star wood.
  • Veneer plywood panels suitable for the purposes of the invention are also referred to as multiplex panels. When the surfaces are coated with phenolic resin, the term screen printing plate is common.
  • the carrier plate is provided on its circumferential edge with a seal, an edge strip or also a closing profile.
  • Sealing can be expedient in particular in the case of wood-based materials in order to provide a smooth, splinter-free and chip-free closure at the edge, which has an improved resistance to mechanical loads and to the penetration of moisture.
  • Corresponding protection can also be achieved by means of edge strips and end profiles, in particular C-shaped end profiles. If, for example, a structured chamber plate is provided as a carrier plate, a closed surface that is flat on the edge is only provided by an end strip or an end profile. For example, a C-shaped End profile can also be compensated for inaccuracies in the cut and the stability can be increased.
  • the carrier plate has a recess for a water drain, a drain fitting usually being arranged there.
  • the sealing layer is brought up to the drain fitting or connected to the drain fitting in a watertight manner.
  • the carrier plate has between 8 and 36 height-adjustable feet on its underside. With an increasing number of feet, there is an even more even distribution of force. On the other hand, the required adjustment of all feet also increases the installation effort. If, according to a preferred embodiment of the invention, the feet are largely evenly distributed on the underside of the carrier plate, nine feet in a 3x3 arrangement, 16 feet in a 4x4 arrangement or 25 feet in a 5x5 arrangement can be provided. Of course, the arrangement of the feet can also be adapted to the actual weight loads. If - as described below - a shower tray as a shower element is simply placed with its C-shaped edge onto the carrier plate from above, the greatest weight loads occur in the edge area. In such a case, a smaller number of height-adjustable feet is generally sufficient on the inner surface of the carrier plate.
  • the outer feet according to the present invention can be arranged further inwards, so that there is just one under the carrier plate Edge area can be left free. If - as already explained above - lines of a house installation are provided under the carrier plate, these are preferably laid at an angle between the wall and floor surface that can be left out of the feet. Furthermore, within the scope of the invention, individual feet can also be relocated relatively easily in their position during assembly.
  • the feet have a supporting body on the underside, an adjusting spindle adjoining the supporting body and a sleeve body arranged around the adjusting spindle, the sleeve body adjoining the underside of the carrier plate.
  • the carrier plate is formed from a wood material
  • the sleeve bodies can be screwed to the carrier plate in a simple manner.
  • a less stable material such as a structural chamber plate is provided for reasons of cost and weight, the acting force can optionally be distributed over a larger area via a support plate, with the support surface of each sleeve body being significantly increased by the associated support plate.
  • the carrier plate has adjustment openings in the area of the feet, so that the carrier plate can then be easily positioned before the sealing layer is formed.
  • the height-adjustable feet can then be adjusted from above through the adjustment openings.
  • the adjusting spindle can then be actuated with a tool in the form of a screwdriver, an Allen key or the like if it has a suitable receptacle.
  • an adjustment opening can then easily be formed in the carrier plate at the corresponding point.
  • such an adjustment opening can simply be drilled as a through hole, in which case the foot to be laid is then arranged at the new position and, for example, screwed to the underside of the carrier plate.
  • a mounting recess is usually formed in a building, which is arranged below an adjacent floor surface. Based on this, for a flush installation of the shower element it is also provided that the upper side of the carrier plate provided with the sealing layer forms a recess with a height of, for example, between 15 mm and 50 mm opposite the adjoining floor surface. This height is then bridged by the shower element inserted subsequently, for example in order to be flush with the adjacent floor area or the floor covering provided there.
  • the sealing layer formed separately from the shower element itself ensures reliable protection of the building structure under all circumstances. Nevertheless, certain impairments cannot be ruled out if there is long-term moisture on the sealing layer. Depending on the material, long-term exposure to moisture may have disadvantages.
  • At least one moisture detector can be arranged on the sealing layer.
  • the moisture detector can be arranged, for example, in the area of the recess in the carrier plate, because there can usually be a small step with regard to the sealing layer, so that water can collect there.
  • a humidity sensor for example, can be provided as the humidity indicator, which is connected to a signal transmitter, an intelligent controller or the like by cable or via a wireless connection in order to indicate a maintenance requirement.
  • the humidity sensor can expediently be equipped with a long-life battery.
  • the humidity detector or humidity sensor works completely independently and then emits a specific noise, for example in the event of damage, as is also known in a similar way from commercially available smoke detectors.
  • a shower tray with a C-shaped tub rim can be provided as the shower element, the shower tray with its tub rim resting directly or indirectly on the sealing layer.

  • a simple profile strip or just a strip of material can be provided as protection against the surface.
  • a thin material with a thickness of up to a few millimeters is usually sufficient for this.
  • Such a thin overlay protection can in principle be provided continuously or not continuously. In the case of a continuous material, this can be made either tight or permeable. It should be noted that the actual protection of the Building serving sealing is provided by the sealing layer formed on the carrier plate.
  • the support protection can also be used in order to be able to compensate for a slight misalignment afterwards by placing a little more material underneath in some areas.
  • the shower tray can be formed from steel enamel according to a preferred configuration of the invention.
  • a shower tray has sufficient stability to be supported essentially on its circumferential edge.
  • An additional central support for improved force distribution is of course also possible.
  • a shower surface is provided on a carrier as the shower element, this shower element then being placed on the sealing layer.
  • the carrier can preferably consist of rigid foam, the flat shower surface, like the shower tray described above, preferably also being made of steel enamel.

  • the shower element can only be positioned at its periphery on the carrier plate within the scope of the invention and otherwise rest loosely or essentially loosely on the carrier plate. If the shower element is positioned and held, for example, with a circumferential joint, in particular a silicone joint, the shower element can easily be removed for maintenance or replacement after cutting open such a silicone joint and loosening the drain fitting. Since the watertight seal is formed independently of the shower element itself, cut protection tapes or the like can then be partly or partially dispensed with with such a silicone joint, depending on the configuration.

  • the collar section is preferably angled at least on a circumferential contact surface with the drain housing with respect to the sealing strip section, in particular angled by approximately 90 °. While the sealing sheet section usually runs horizontally or approximately horizontally, the contact surface extends approximately perpendicularly.
  • the circumferential contact surface should also have a suitable height of, for example, between 5 mm and 50 mm. If the height is too low, there is a risk of insufficient sealing, depending on the design. On the other hand, there must be a corresponding height on the outside of the drain housing for the collar section to rest.
  • the outside of the drain housing is circular-cylindrical or somewhat circular-cylindrical in the area of the contact surface, so that the collar section with a circular opening can then be arranged in any angular position.

  • the foot 8 comprises a supporting body 9 on the underside, an adjusting spindle 10 adjoining the supporting body 9 and a sleeve body 11 arranged around the adjusting spindle, which adjoins the underside of the carrier plate 7 and is screwed there in the illustrated embodiment.
  • the sleeve body 11 has an internal thread in a manner known per se, so that the height of the feet 8 can be adjusted by actuating the adjusting spindle 10.
  • the carrier plate 7 has an adjusting opening 12 for each foot 8 which is accessible from above and through which the adjusting spindle 10 is accessible from above with a tool.
  • the adjusting spindle 10 has a corresponding tool holder shape for this purpose.
  • the carrier plate 7 has a recess 13 in the area of the drain housing 4 of the drain fitting.
  • the carrier plate 7 is otherwise completely flat on its upper side.
  • the height-adjustable feet 8 allow the support plate 7 to be adjusted and aligned in terms of its height. It is provided that a completely flat surface is provided on the upper side of the carrier plate 8, while the mounting recess 1 can also have unevenness due to the adjustable feet 9.
  • a sealing layer extending to the drain housing 4 is then formed, which is also watertightly connected to the adjoining structural surfaces, namely the floor surface 2 and the wall surfaces 3.
  • a drain seal 14 with a sealing membrane section 15 already attached to it in a watertight manner is placed in the area of the drain housing 4.
  • the drainage seal 14 is then clamped in a sealing manner on the drainage opening 5 of the shower element, the seal beginning there being guided away from the drainage housing 4 through the sealing strip section 15.
  • a sealing material 16 is applied over the entire surface of the carrier plate 7 and in an overlap with the sealing sheet section 15, which sealing material also extends to the adjoining structural surfaces, namely the floor surfaces 2 and the wall surfaces 3.
  • a sealing layer that is completely closed up to the drainage seal 14 is thus formed.
  • the Sealing material can be formed in front of a prefabricated sealing membrane and / or a sealing coating without restriction.
  • sealing sheets in the form of a film, a composite material or a waterproof fleece can also be combined with sealing coatings.
  • the sealing material 16 is arranged on the sealing sheet section 15. It goes without saying that a reverse arrangement is also possible.
  • the shower space substructure is then completed and ready to accommodate the shower element.
  • a shower element in the form of a shower tray 17 is placed on the carrier plate 7. Since the sealing layer described above ensures the necessary protection of the structure from water, an expensive seal on the shower tray 17 itself is not necessary. So it is sufficient if - as in the Fig. 6 is indicated - that in the Figures 1 and 2
  • the drain housing shown with the drain seal 14 is pressed against the underside of the shower tray 17 at the drain opening 5 by a clamping ring 18 arranged from above.
  • a maintenance expansion joint running around the shower tray 17, which is also referred to as a silicone joint 19, can then also be formed, which can then even provide adequate protection against slipping.
  • the shower tray 17 is therefore largely loosely placed on the carrier plate 7. After removing the silicone joint 19 and loosening the clamping ring 18, the shower tray 17 can, if necessary, also be raised again relatively easily and, if necessary, exchanged.
  • the floor surface 2 and the wall surfaces 3 are tiled provided, with corresponding coverings in the following described in detail Fig. 7 and 8th are indicated.
  • the silicone joint is then only formed after tiling.
  • a shower surface on a carrier can also be used as a shower element, for example.
  • the shower tray 17 which is provided as a shower element in the exemplary embodiment, projects slightly upwards in relation to the adjoining floor surface 2. This difference in height is provided in order to achieve a precisely flush transition after tiles have been placed on the floor surface 2.
  • the shower tray 17 with its C-shaped tub rim 20 is placed in a simple manner on the carrier plate 7 via a thin support protection 21.
  • the support protection 21 can also support a releasable fixing of the shower tray 17 on the carrier plate 7 or the holding of the shower tray 17 in the desired position.
  • a gap remains which - as described above - can be filled by the silicone joint 19. It can also be seen in the sectional illustration that a completely closed sealing layer has been produced, which turns out to be a closed sealing plane extends below the shower tray 17 and to the side of the shower tray 17 onto the floor surfaces 2 and the wall surfaces 3.
  • the applied sealing material 16 is arranged in an overlap with the sealing strip section 15.
  • the sealing web section 15 adjoins the drainage seal 14 in a materially bonded manner, which has an elastomeric ring body 22 and an essentially flat collar 23 running around the ring body 22.
  • the cohesive transition to the sealing strip section 15 is provided on the collar 23, for which purpose, for example, welding or gluing is provided.
  • the drain fitting is integrated into the sealing layer on the carrier plate 7 described above during sealing. It can also be seen how the drain seal 14 and the drain housing 4 are pulled from below by the clamping ring 18 against the underside of the shower tray 17 at the drain opening 5.
  • Fig. 8 further optional configurations are shown.
  • an insulating material 24 for sound decoupling can be provided on the edge of the carrier plate 7.
  • a moisture sensor 25 is shown adjacent to the drain housing 4 on the upper side of the sealing strip section 15, which can trigger an alarm signal in the event of an accumulation of liquid.
  • the humidity sensor 25 can be connected to a control device, a display device or the like with connecting lines or wirelessly be connected. In principle, it is also possible for the humidity sensor 25 to only emit an acoustic warning signal.
  • the elastomeric ring body 22 and the drainage housing 4 have mutually complementary interlocking contours 26 in the form of interlocking projections and depressions. It is thus possible to position the drainage seal 14 with the adjoining sealing strip section 15 in the correct position on the drainage housing 4 during assembly, before the final fastening and fixing with the clamping ring 18 takes place.
  • the drainage seal 14 can subsequently be moved with respect to its horizontal alignment at least to a certain extent in order to be placed in the correct position on the drainage housing 4.
  • a certain adjustment may be necessary, for example, if the drainage seal 14 with the sealing strip section 15 adjoining it slipped or inaccurately placed during assembly.
  • the Fig. 8 an annular movable compensating area 27 of the sealing strip section 15 is indicated as an optional configuration, for which the sealing strip section 15 can have a wave shape, folds or a comparable material supply there, for example.
  • the sealing sheet section can be partially or completely easily elastically and / or plastically stretchable in the plane without losing its sealing properties.
  • FIG. 8 It can be seen that due to the uniform distribution of force over the large number of feet 9, an edge area 28 remains under the carrier plate as a mounting space, so that components of a house installation can be laid there in the angle between the wall surface 3 and the bottom of the mounting recess 1.
  • a line 29a for waste water and lines 29b of a heating system are indicated by way of example. If necessary, individual feet 9 can also be easily relocated during assembly.
  • the carrier plate 7 has a C-shaped end profile 30 on its edge as a straight end and protection.
  • the drainage seal 14 and the sealing sheet section 15 are formed in one piece from the same material.
  • a body made of elastomeric plastic is thus formed, then according to the respective function Subregions of the drainage seal 14 with its annular body 22 on the one hand and the sealing strip section 15 on the other hand are assigned.
  • the drainage seal 14 on the one hand and the sealing sheet section 15 on the other hand can be clearly distinguished from one another despite the material transition.
  • the drainage seal 14 has the ring body 22 and the flat collar 23 adjoining it, but the material-to-material transition between the collar 23 and the sealing sheet section 15 is designed differently.
  • the collar 23 and the sealing sheet section 15 are welded to one another, for which purpose at least one weld seam 32 is provided around the circumference of the collar.
  • a material connection is possible in the case of thermoplastic materials.
  • a material connection can be achieved by vulcanization or a comparable crosslinking reaction.
  • the collar 23 and the sealing strip section 15 are injection molded onto one another.
  • the drainage seal 14 and the sealing sheet section 15 can be formed simultaneously in a multi-component injection molding process or also one after the other. It is thus also possible to subsequently inject the drainage seal onto a blank of a material web formed in another way for the sealing web section 15.
  • FIG Figure 9D also a form fit.
  • the Figures 9A through 9F show the section through an overall ring-shaped closed arrangement.
  • the Figure 9E shows starting from the Figure 9B a variant in which, in addition to the adhesive 31 between the drainage seal 14 and the sealing strip section 15, an integral connection is achieved by an additional ring of an adhesive tape 33.
  • Such a ring-shaped adhesive tape 33 alone is sufficient for a material connection, which can be arranged on one side or on both sides.
  • the drainage seal 14 and the sealing sheet section 15 do not have to be arranged in an overlap, so that the previously described stretchable compensation area 27 can also be formed by the adhesive tape 33 if this is slightly elastic and / or plastically stretchable.
  • the sealing membrane section is shown interrupted, shows the Figure 10A the overall arrangement of drainage seal 14 and sealing sheet section 15, the already in Fig. 8 indicated compensation area 27 can be seen.
  • the sealing sheet section 15 runs in the compensation area 27 in a wave shape.
  • other shapes are also possible which keep a supply of material ready for a movement.
  • the waveform or an alternative shape configuration can be generated in different ways.
  • the sealing sheet section 15 can be reshaped by the action of pressure and / or temperature.
  • the sealing sheet section can also be partially or completely slightly elastic to a sufficient extent and / or be plastically extensible without losing its sealing properties.
  • the compensation area 27 is formed on the drainage seal 14 as an alternative. If the drainage seal 14 is formed, for example, in a mold by injection molding a thermoplastic material or the vulcanization of a thermosetting polymer, the compensation area 27 can then be predetermined by the mold.
  • the different configurations also show that the different types of material connections, such as gluing and welding, can be combined with one another. Especially when the sealing sheet section 15 and / or the drainage seal 14 is / are sticky due to the choice of material, a material connection can be achieved without a separate adhesive. In practice, such materials are also referred to as self-erosing, in which case a distinction between gluing and welding is not immediately necessary.
  • the Fig. 11 shows a second embodiment of the drain fitting in a representation corresponding to FIG Fig. 8 .
  • the drain fitting also comprises a drain housing 4, a clamping ring 18 and a drain seal 14.
  • a sealing plane is brought up to and connected to the drain fitting as described above.
  • a sealing arrangement is provided which has an elastically stretchable collar section 34 and a sealing sheet section 15 '.
  • the collar portion 34 rests on the drain housing 4 between an inlet opening on the upper side and a drain nozzle 35 sealingly on an outside, whereby solely through the elastic abutment or additionally through an optional adhesive bond provides a reliable seal. At least on the contact surface, the collar section 34 extends vertically downward, the drain housing 4 extending through a central opening in the collar section. The height of the contact surface between the collar section 34 and the outside of the drain housing can be between 5 mm and 50 mm, for example.
  • a compensation area 27 is provided for position adjustment in the horizontal and / or vertical direction.
  • the compensation area can also be formed from a separate material which is connected in a water-tight manner to the collar section 34 and the sealing sheet section 15 'in a suitable manner, for example by gluing or welding.
