    The invention relates to a shower substructure with a recess for a water drain having support plate for receiving a shower element and a plurality of height-adjustable feet on an underside of the support plate.
    [0002] Shower space substructures that have a flat or essentially flat support plate and are intended to accommodate a separate shower element, for example a shower tray, are disclosed in GB 2 478 055 A, DE 20 2016 101 225 U1 and DE 20 2008 005 293 U1 known.
    In the last-mentioned document, a relatively large number of feet is arranged distributed not only on the edge, but also on the intermediate surface of the carrier plate in an advantageous manner, so that a particularly uniform and reliable support is possible. The height-adjustable feet are arranged on the underside of the support plate, i. H. there they extend from the carrier plate in the direction of a substrate. However, the individual feet are accessible from above through corresponding openings, so that the carrier plate can also be easily aligned from above during assembly when the carrier plate has already been set up. Corresponding measures are also possible and expedient within the scope of the present invention, which is described in detail below.
    The shower space substructures known from the prior art with a carrier plate essentially serve to provide a flat surface at a desired, predetermined height on which a separate shower element, for example a shower tray, can then be placed. The shower element then has on its upper side the gradient on its upper side which is necessary for the water drainage, while the lower side is set up for the arrangement on the flat or at least substantially flat carrier plate. Accordingly, as described above, the main task of the shower space substructure is to provide the level support surface at the desired height.
    Due to the free space below the carrier plate, a drain pipe and a drain set can initially be positioned simply and easily in the formation of the shower space substructure. Since the carrier plate is supported by the height-adjustable feet, the surface on which the feet rest does not have to be level. A slope and unevenness can be easily compensated for with the height-adjustable feet. The support plate can be aligned using a spirit level, for example, in which case the desired height can then also be set precisely and, with simple manual skill, even inexperienced persons can achieve uniform, flat support. For this purpose, when adjusting the height and the horizontal alignment of the carrier plate, the individual height-adjustable feet must be brought down so far that there is a noticeable force support and none of the feet can be freely rotated without applying force, i.e. H. "Hangs in the air".
    When setting up a shower area, a watertight seal is also necessary in order to avoid impairment of the building structure in the event of leaks, overflow of the shower element, in particular a shower tray, or other influences. According to the German standard DIN 18534-1: 2017-07, various sealing construction methods are proposed, whereby a sealing layer can be arranged at different heights in a multi-layer installation.
    In shower trays and comparable shower elements, the shower element is usually connected in a watertight manner to adjacent building surfaces during assembly. In the case of a conventional shower tray with a C-shaped tub rim, for example, a sealing tape, if necessary with prefabricated sealing corners, can be glued all around the vertical lateral surfaces, this sealing tape or sealing corners then being integrated into a sealing layer that extends to the adjacent building surfaces.
    [0008] Sealing paints which are known in various formulations can also be used for this purpose. In the context of the invention, sealing paint is understood to mean both comparatively low-viscosity materials and pasty, in particular cement-containing systems such as sealing slurries. While comparatively thin-bodied sealing coatings can be applied, rolled or sprayed, paste-like materials are usually filled with a spatula or processed using a trowel.
    With regard to a bottom-side seal, reference is made to DE 10 2014 104 943 A1 and WO 2005/046414 A1. The overall construction is relatively complex, and relatively large spaces can be filled with water. Drainage lines must then also be provided below the actual sealing level.
    According to DE 20 2016 002 387 U1, DE 20 2017 003 602 U1 and EP 2 206 456 A2, a sealing layer runs directly below a partially tiled surface, so that the sealing layer itself at least partially with the gradient provided for the water drainage is arranged.
    Against the background of the prior art, the present invention is based on the object of specifying a shower space substructure which is easy to handle, has good functional properties and also enables the easy arrangement of a separate shower element on the shower space substructure. Accordingly, an entire shower area and a method for creating the shower area should also be specified.
    The subject of the invention and the solution to the problem are a shower space substructure according to claim 1, a shower space according to claim 11 and a method for forming a shower space according to claim 17.
    Based on a generic shower space substructure, it is thus provided within the scope of the invention that a sealing layer is arranged directly on an upper side of the carrier plate, the sealing layer being 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. For the formation of the sealing layer, 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 an adhesive layer material, in which case corresponding surfaces can also be covered by a release paper, a release film or the like before processing. For sealing purposes, for example, butyl plastics in the form of tapes or sheets can be used, which have good adhesive or self-adhesive properties. Reference is also made to the publication "IVD data sheet No. 5, November 2014 edition, Sealing with butyl tapes - properties, processing, areas of application" as an example. Of course, 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 explained above, sealing membranes, sealing tapes, sealing corners and comparable components can be combined to form the watertight sealing layer and, in particular, 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.
    According to the invention, the seal takes place in an intermediate plane 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.
    According to the invention, the sealing layer is formed on the top of the carrier plate, which is flat or at least substantially 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 of the invention is that a cavity remains under the support 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.
    Even if these house installation lines have to be serviced in retrospect, dismantling is still relatively easy - as will be described in more detail below - compared to house installation lines laid in walls or a screed.
    Of course, in the normal operation of the shower area, all the water from the shower element, so in particular a shower tray, should be diverted through a drain. If, however, there are leaks in the area of the shower element and the shower element overflows, 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.
    This also makes it possible within the scope of the invention that the shower element is installed particularly easily after the desired height has already been provided beforehand by positioning the carrier plate by means of the height-adjustable feet. 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 a conventional drain fitting can be used.
    The installation of the shower element is then particularly simple and can possibly even be done by laypersons, because the building-safe seal is then already in place and completely finished. The shower element can thus also be easily removed again without the building-safe seal being impaired. With the same dimensions, 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.
    Even after a long standing time of the shower space substructure in the assembled state, the tightness can 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.
    In the context of the invention, there are various design options. Thus, according to a preferred embodiment of the invention, it is provided that the carrier plate is 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.
    For reasons of cost and weight, for example, composite materials and structural chamber panels come into consideration, such as those sold by Interplast Kunststoffe GmbH under the name Triplex, for example. However, carrier plates made of a wood material are also particularly suitable. In addition to simple chipboard and, in particular, OSB panels, 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.
    According to one embodiment of the invention, the carrier plate is provided on its circumferential edge with a seal, an edge strip or also an end 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. In the case of a C-shaped end profile, for example, inaccuracies in the cut can be compensated for and the stability can be increased.
    According to the invention, the carrier plate has a recess for a water drain, a drain fitting usually being arranged there. The sealing layer is expediently brought up to the drain fitting or connected to the drain fitting in a watertight manner. Since the sealing layer is then not supported directly on the recess, the sealing layer there preferably has a sealing web section, in particular a sealing film section.
    In this context, it should be noted that the term sealing film generally refers to flexible plastic-based laminates, which of course can also be provided with a reinforcement in the form of an internal or overlying grid, a fleece or the like.
    In such a sealing strip section there may also be a need for a certain mobility, for example in order to be able to compensate for inaccuracies in the positioning of the sealing strip section with respect to the drain fitting when assembling the drain fitting. The sealing sheet section can have a compensation area, for example, by means of a wave or fold shape running around the drain fitting.
    Additionally or alternatively, 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 recess is usually larger than the drain fitting to be arranged in it, so that during assembly the drain fitting can be inserted into the recess with air, i.e. circumferentially 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.
    The drain fitting usually comprises at least one drain housing below a drain opening of the shower element and a clamping ring above the drain opening of the shower element, the clamping ring then being connected to the drain housing through the drain opening of the shower element, thereby providing a clamping attachment. With such a clamping attachment, for example by screwing, a seal can be achieved in a known manner with a drain seal, which is then elastically compressed between the bottom of the shower element and the top of the drain housing.
    As already explained above, the sealing layer is to be brought up to the drain fitting or to be connected to the drain fitting in a watertight manner. A sealing film provided on the sealing layer can, for example, simply be clamped in with the described configuration of the drain fitting with drain housing, clamping ring and drain seal. In principle, configurations are also considered in which the sealing film of the sealing layer replaces the drainage seal. Finally, it is also possible to connect the sealing layer to the drain fitting independently of the drain seal described above, for example to connect it to the drain housing at a different position, in particular to glue it. For this purpose, the drain fitting and in particular the drain housing can have a connection surface independently of the drain seal, for example. Such a connection is possible both on site during assembly and at the factory.
    According to a particularly preferred embodiment of the invention, however, it is provided that in the described embodiment of the drain fitting with a drain housing, a clamping ring and a drain seal between the drain housing and the clamping ring, the drain seal has an elastomeric ring body with which the drain seal on the Drain body is in place. A flat sealing membrane or sealing film section, extending away from the drain housing, can then adjoin the elastomeric ring body in a materially bonded manner, this embodiment of the drain fitting having an independent inventive excess being explained in more detail below.
    According to a preferred embodiment of the invention, 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.
    In comparison to frame-shaped pedestals known from the prior art, the outer feet according to the present invention can be arranged further inside, so that just an edge area can be left free under the carrier plate. If - as already explained above - lines of a house installation are provided under the carrier plate, then 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.
    According to a preferred embodiment of the invention, 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. If, according to a preferred embodiment of the invention, the carrier plate is formed from a wood material, the sleeve bodies can be screwed to the carrier plate in a simple manner. If, on the other hand, 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.
    In order to enable easy handling, it is provided according to a preferred embodiment of the invention that the carrier plate has adjustment openings in the area of the feet, so that the carrier plate can then be easily positioned before the formation of the sealing layer. In particular, the height-adjustable feet can then be adjusted from above through the adjustment openings. For example, 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.
    When the sealing layer is produced, the adjustment openings are then covered or closed.
    If individual feet are repositioned during assembly, for example for the laying of lines in a house installation, an adjustment opening is then to be formed in the carrier plate in a simple manner at the corresponding point. In the case of a wood material, 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.
    In order to arrange the shower space substructure, 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.
    As already explained above, a reliable protection of the building structure is achieved under all circumstances by the sealing layer formed separately from the shower element itself. 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.
    Against this background, according to a further development of the invention, 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 detector, 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. In the case of wireless transmission, the humidity sensor can expediently be equipped with a long-life battery. Finally, it is also possible that 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.
    The invention also relates to a shower area with the shower area substructure described above and with a shower element received on the carrier plate.
    According to a first variant of the invention, a shower tray with a C-shaped tub rim is provided as a shower element, the shower tray resting with its tub rim directly or indirectly on the sealing layer. For example, the edge of the tub can rest over a comparatively thin protective cover with a height of a few millimeters. For example, 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 seal serving to protect the building is provided by the sealing layer formed on the carrier plate.
    If necessary, 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.
    In particular in the case of an embodiment with a C-shaped tub rim, the shower tray can be formed from steel enamel according to a preferred embodiment of the invention. There is then also the advantage that such 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.
    Of course, other configurations of a shower tray without a C-shaped tub rim and / or other types of support on the carrier plate are also possible within the scope of the invention.
    According to a variant of the invention it is provided that a shower surface is provided on a carrier as a 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.
    As already ringing before, in the shower area under the carrier plate, in addition to the drain fitting, a more extensive house installation that is also independent of the shower area itself can be provided. Due to the secure sealing at the top, this free space can be used, for example, for the arrangement of house installation lines that carry electricity, fresh water or waste water, for example.
    By providing the shower space substructure as a flat, already completely sealed surface, 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 invention also relates to a method for forming the shower space described above, wherein successivelya mounting recess is formed in a building, which is arranged below an adjacent floor surface,a drain fitting is installed in the installation recess,a support plate with height-adjustable feet on one underside is inserted into the mounting recess in such a way that the drain fitting remains accessible from above through a recess,the support plate is aligned horizontally by adjusting the feet,on an upper side of the carrier plate, a waterproofing layer is connected to all structural surfaces surrounding the mounting recess anda shower element is preferably placed on the carrier plate without an additional complete seal.
    As already explained above, a particularly advantageous aspect of a preferred embodiment relates to the drain fitting with the drain housing, the clamping ring and the drain seal between the drain housing and the clamping ring, the drain seal being placed on the drain housing with an elastomeric ring body. It is provided that a flat sealing strip section extending away from the drain housing adjoins the elastomeric ring body in a materially bonded manner. This enables the sealing level 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.
    There are then various options for further detailed design. It can thus be provided that the elastomeric ring body and the sealing strip section are formed in one piece from a uniform elastomer material. The ring body corresponding in its cross section to a conventional drainage seal can then be formed together with the sealing strip section in a primary molding process. Both 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.
    According to an alternative embodiment of the invention, it is provided that 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. However, injection molding can also be carried out with the same material or two different materials in two steps.
    For example, 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.
    According to a further variant it is provided that 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. In order to achieve a permanent and watertight bond, for example 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 take place by applying heat 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.
    In principle, different types of connection, that is to say in particular different types of gluing and / or welding, can also be combined with one another.
    In order to enable injection molding, gluing or welding, the drainage seal can have a collar running radially around the ring body and preferably flat or substantially flat collar on its underside and upper side, to which the sealing strip section then adjoins.
    Regardless of the specific design of the material connection of the drainage seal and sealing sheet section, it goes without saying that a sufficient material thickness and material strength must be provided for the material connection. In particular, a simple O-shape of the drainage seal is not, or at least not readily, suitable within the scope of the embodiment described.
    In a one-piece configuration made of a uniform elastomer material and when the sealing strip section is molded onto the drain seal, it is clear that the sealing strip section and the drain seal together form a pre-produced, cohesive module before the drain fitting is installed on a sanitary tub. During assembly, the sealing sheet section and the drain seal are then positioned as a coherent module on the drain housing.
    In the case of other types of material connection as well, that is to say in particular in the case of gluing or welding, it is preferred if the 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.
    If the sealing sheet section according to the variants described above is first manufactured separately from the drainage seal, other materials with different properties can also be provided for this purpose. 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.
    If a multilayer structure is provided, it goes without saying that a full-surface continuous layer or full-surface protection is only necessary with regard to the barrier effect against water. Supplementary layers, such as, for example, a cover layer made of fleece, a reinforcement or the like, can also only be provided in certain areas.
    As already ringing before, a uniform, continuously tight transition from the drainage seal to an adjoining sealing surface can be achieved within the scope of the invention. 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.
    For this purpose, the elastomeric ring body and the receiving housing can have mutually complementary interlocking contours with at least one projection and at least one recess receiving the projection. With such interlocking projections or ribs, the elastomeric ring body can then be prepositioned and protected against slipping even before the clamping ring is assembled.
    In the case of a conventional clamping of the drain seal, a support with respect to the drain housing usually only takes place directly on the ring body. 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.
    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 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.
    Against this background, the sealing membrane section preferably covers an area of at least 0.04 m and in particular at least 0.09 m, based on 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. Of course, the size of the sealing sheet section can also be selected to be larger, depending on the respective requirements.
    The invention is explained below with the aid of a drawing showing only one exemplary embodiment. 1 to 4 show the steps for forming a shower space substructure, FIGS. 5 and 6 show a shower space with the shower space substructure described above and a shower element placed on it, FIG. 7 shows a longitudinal section through the shower space according to FIG. 6 at a distance from a water drain, FIG. 8 is an enlarged sectional view in the area of the water drain.
    1 shows an area of a building in which first a shower space substructure and then a shower space are to be formed by the arrangement of a shower element. For this purpose, an assembly recess 1 is formed in the structure, which is arranged in a corner of the room below an adjacent floor surface 2.
    The arrangement in a corner of the room with the floor surface 2 adjoining two sides of the mounting recess 1 and wall surfaces 3 adjoining two sides is only an example. The shower area can be formed in a comparable manner on only one wall surface 3, in a niche with three wall surfaces 3 or within an otherwise continuous floor surface 2.
    In the context of the invention, the wall surface 3 can also be formed, for example, by a front wall and by a vertical surface of a base or a step. Since different configurations come into consideration within the scope of the invention, only the immediate corner area of the structure is shown, with the wall surface 3 also being illustrated cut off upwards. The bottom surface 2 is only shown as a section.
    The floor surface 2 adjoining the assembly recess 1 is preferably designed to be flat or essentially flat, in order to subsequently apply a cover material such as tiles, for example. As will be explained in more detail below, certain unevennesses can be accepted within the mounting recess 1 because a shower space substructure that is adjustable in height and adaptable is formed there.
    According to FIG. 1, a drain housing 4 of a drain fitting is first positioned there where a drain hole 5 is provided in the shower element to be subsequently positioned. The drain housing 4 is already connected to a drain line 6.
    According to FIG. 2, a support plate 7 with a total of 16 height-adjustable feet 8 is inserted into the mounting recess 1 to form the shower space substructure. The carrier plate 7 can be formed from a wood material, in particular a plywood. With such a configuration of the carrier plate 7, the feet 8 can be screwed and / or inserted from below onto the underside of the carrier plate 7 in a particularly simple manner.
    In this context, a foot 8 is also shown as an example in FIG. 2. Accordingly, 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.
    In order to enable a slight rotation of the adjusting spindle 10, the carrier plate 7 has for each foot 8 an adjusting opening 12 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.
    It can already be seen in FIG. 2 that the upper side of the carrier plate 7 also jumps back downwards with respect to the adjoining floor surface 2. As can also be seen below, this difference in height is intended to enable a flush arrangement despite the height of a shower element arranged on the shower space substructure. A flush arrangement is usually provided after completion of the entire sanitary arrangement, in which case a cover material provided there, such as tiles, must also be taken into account on the floor surface 2.
    After the support plate 7 has been arranged and horizontally aligned with the aid of the feet 8, a sealing layer extending to the drain housing 4 is then formed, which is also connected in a watertight manner to the adjoining structural surfaces, namely the floor surface 2 and the wall surfaces 3. For this purpose, according to FIG. 3, a drainage seal 14 with a sealing membrane section 15 already attached to it in a watertight manner is placed in the area of the drainage housing 4. The drainage seal 14 is then clamped in a sealing manner on the drainage hole 5 of the shower element, the seal beginning there being guided away from the drainage housing 4 through the sealing strip section 15.
    Subsequently, according to FIG. 4, a sealing material 16 is then applied over the entire surface of the carrier plate 7 and in an overlap with the sealing strip section 15, which 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. In particular, sealing sheets in the form of a film, a composite material or a waterproof fleece can also be combined with sealing coatings. According to FIG. 4, the sealing material 16 is arranged on the sealing sheet section 15. It goes without saying that a reverse arrangement is also possible.
    According to FIG. 4, the shower space substructure according to the invention is then completed and ready for receiving the shower element.
    According to FIG. 5, a shower element in the form of a shower tray 17 is placed on the carrier plate 7 for this purpose. 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. It is therefore sufficient if, as indicated in FIG. 6, the drain housing with the drain seal 14 shown in FIGS. 1 and 2 is pressed against the underside of the shower tray 17 at the drain hole 5 by a clamping ring 18 arranged from above.
    In addition, 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 releasing the clamping ring 18, the shower tray 17 can, if necessary, also be raised again relatively easily and, if necessary, exchanged.
    According to the exemplary embodiment, after the shower tray has been inserted, tiling of the floor surface 2 and the wall surfaces 3 is also provided, corresponding coverings being indicated in FIGS. 7 and 8, which are described in detail below. The silicone joint is then only formed after tiling.
    Instead of the shower tray 17 shown, a shower surface on a carrier can also be used as a shower element, for example.
    Further details of the arrangement according to the invention emerge from FIGS. 7 and 8.
    In the sectional illustration in FIG. 7, it can also be seen initially that the carrier plate 7 is completely flat. 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.
    According to the detailed view according to FIG. 8, 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.
    Opposite the shower tray 17 and the adjoining structural surfaces in the form of the floor surfaces 2 and the wall surfaces 3, 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 is produced, which extends as a closed sealing plane below the shower tray 17 and to the side of the shower tray 17 onto the floor surfaces 2 and the wall surfaces 3.
    In the detailed view of FIG. 8, it can be seen that the applied sealing material 16 is arranged in an overlap with the sealing strip section 15.
    The sealing strip section 15 adjoins the drainage seal 14 in a materially bonded manner, which on the one hand 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.
    It can also be seen from FIG. 8 that the drain fitting is integrated into the previously described sealing layer on the carrier plate 7 due to the sealing strip section 15 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 hole 5.
    According to FIG. 8, further optional configurations are shown. For example, an insulating material 24 for sound decoupling can be provided on the edge of the carrier plate 7. Furthermore, a moisture sensor 25 is shown adjacent to the drain housing 4 on the upper side of the sealing sheet section 15, which can trigger an alarm signal in the event of an accumulation of liquid. For this purpose, the humidity sensor 25 can be connected to a control device, a display device or the like with connecting lines or wirelessly. In principle, it is also possible for the humidity sensor 25 to only emit an acoustic warning signal.
    It can also be seen from FIGS. 7 and 8 that a reliable seal is formed largely independently of the shower tray 17 by the sealing layer. Even if water collects on the edge or below the shower tray 17, the surrounding building structure is still safely protected. In such a case, dewatering or drying can then take place in a relatively easy manner. On the one hand, the clamping ring 18 can be loosened so that drying and dewatering is then possible in the area of the drain, which is preferably the deepest point of the sealing layer. In addition, as described above, the entire shower tray 17 can also be relatively easily dismantled and lifted off within the scope of the invention.
    In order to facilitate assembly, in the case of the drain seal 14, the elastomeric ring body 22 and the drain housing 4 have mutually complementary positive-locking 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.
    With regard to the steps shown in FIGS. 1 to 4, it can be useful if the drain seal 14 can be moved at least to a certain extent with respect to its horizontal orientation afterwards, in order to be placed in the correct position on the drain housing 4. A certain adjustment may be necessary, for example, if the drainage seal 14 with the sealing strip section 15 adjoining it slips during assembly or is placed inaccurately. For this purpose, an annular, movable compensation area 27 of the sealing strip section 15 is indicated as an optional configuration in FIG. 8, for which the sealing strip section 15 can for example have a wave shape, folds or a comparable material supply. Additionally or alternatively, the sealing sheet section can be elastic and / or plastic, partially or completely, easily stretchable in the plane, without losing its sealing properties.
    Furthermore, it can be seen in FIG. 8 that due to the uniform force distribution over the plurality of feet 9, an edge area 28 remains under the carrier plate as a mounting space, so that there in the angle between the wall surface 3 and the bottom of the mounting recess 1 components of a house installation can be laid. 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.
    As a further optional embodiment, the carrier plate 7 has a C-shaped end profile 30 on its edge as a straight end and protection.
