Definitions

the invention relates to a shower tray device according to the preamble of claim 1 and a room floor in which such a shower tray device is integrated, and a method for installing a shower tray device in a room floor.
shower trays were originally designed in the manner of a tub, which has a horizontally running tub floor with a drain opening and tub walls extending vertically upwards away from it, typically 20 cm to 30 cm in vertical height, shower trays have recently been designed increasingly flatter, so that In modern shower trays, the shape of the tub is only slightly indicated and the walls of the tub only extend a few centimetres.
the flatter design of modern shower trays not only serves to create a modern look for a shower, but also to make it easier to enter the shower.
the shower trays have a considerable horizontal extension, usually of at least 80 cm x 100 cm or at least 90 cm x 90 cm and they should be designed to be as unyielding as possible over its horizontal extension and a robust support in relation to a subfloor on which they are arranged is required, which means a vertically thick overall structure and a contouring of the shower tray or its support that generates stability in the area of support, makes it necessary.
special precautions must therefore be taken when using a conventional shower tray.
the shower tray is installed as part of a shower tray device which has a support on which the shower tray is mounted.
the carrier is usually installed on an unfinished floor, after which a supporting covering, which is usually and preferably realized as a screed, but can also be realized, for example, using a combination of wooden elements and filler, is applied around the carrier, which is so far vertically above the carrier protrudes as the shower tray extends beyond the support due to its vertical extension.
a supporting covering which is usually and preferably realized as a screed, but can also be realized, for example, using a combination of wooden elements and filler
Another alternative for realizing a shower floor that is accessible at floor level can be realized in that at least one section of the room floor of a bathroom is configured as a shower floor.
a drainage channel is provided in the supporting covering and the supporting covering is designed with a gradient towards the drain channel , so that the supporting surface can then be tiled or covered with a conventional floor covering, for example floor tiles, vinyl panels, a plastic floor cast or laid on the supporting surface, for example epoxy resin floor, or a cement-based covering, with the floor covering extending to the drainage channel.
a conventional floor covering for example floor tiles, vinyl panels, a plastic floor cast or laid on the supporting surface, for example epoxy resin floor, or a cement-based covering, with the floor covering extending to the drainage channel.
the present invention is based on the object of providing a shower tray device, a support for a floor element of a shower tray device, a room floor and/or a method for installing a shower tray device in a room floor, with which at least one disadvantage is at least partially eliminated, which is the case with conventional manufacturing techniques of a shower floor.
the invention proposes a shower tray device with the features according to claim 1 .
the shower tray device includes a floor element.
the floor element extends along a horizontal plane in a horizontal longitudinal direction with a length of at least 60 cm, in particular at least 80 cm, and in a horizontal transverse direction with a width of at least 60 cm, in particular at least 80 cm. Longitudinal and transverse directions are perpendicular to each other and span the horizontal plane.
the floor element preferably has a width of at least 80 cm and a length of at least 100 cm, in particular at least 120 cm.
the floor element preferably has a width of at least 90 cm, in particular at least 100 cm, and a length of at least 90 cm, in particular at least 100 cm.
the floor element has a width of at least 80 cm, in particular at least 90 cm, in particular at least 100 cm, and a length of at least 120 cm, in particular at least 140 cm.
the floor element has a drainage opening within its horizontal extension.
the drain opening extends vertically through the floor element and thus from its vertical upper side to its vertical lower side. Water that has reached the top of the floor element can be discharged downwards under the floor element through the drainage opening.
the drainage opening is provided entirely within a horizontal drainage section of the floor element, which forms a substantial part of the horizontal extent of the floor element.
It preferably forms at least 10%, in particular at least 20%, preferably at least 30% of the horizontal extension of the floor element and/or extends horizontally over at least 400 cm 2 , in particular at least 600 cm 2 , in particular at least 1000 cm 2 and thus forms a correspondingly flat horizontal extension of the floor element.
the drain section preferably forms an uninterrupted, closed peripheral edge around the drain opening; the drain section preferably extends in all horizontal directions over at least 3 cm, in particular at least 5 cm, away from the edge enclosing the drain opening, so that it surrounds the drain opening with a corresponding one forms a solid section running around the horizontal extension, within which, for example, a drain pot, as explained in more detail below, can be arranged on the underside of the floor element in a sealing manner around the drain opening.
the drainage section preferably forms the supporting surface of the base element, which is explained in more detail below, horizontally outside the drainage opening.
the floor element is preferably designed in the manner of a plate whose plate surfaces form the top and bottom of the floor element and whose narrow plate sides run vertically and connect the plate surfaces to one another.
the floor element is preferably designed in the manner of a plate made of solid material, ie the plate volume of the plate is filled with the solid material.
the solid material can be a mineral cast or a PU foam, for example.
the floor element has a vertical thickness of at most 20 mm, in particular at most 15 mm, at least at a first longitudinal end over its entire transverse extent and at a first transverse end over its entire longitudinal extent. in particular less than 13 mm, in particular less than 12 mm, in particular less than 11 mm.
the floor element has a vertical thickness of at least 5 mm, in particular at least 10 mm, at least at a first longitudinal end over its entire transverse extent and at a first transverse end over its entire longitudinal extent.
the first longitudinal end defines an absolute end of the floor element with respect to the longitudinal direction
the first transverse end defines an absolute end of the floor element with respect to the transverse direction. Since the floor element has a correspondingly low vertical thickness at its first longitudinal end over its entire transverse extent, i.e. over its entire extent in the transverse direction, the floor element can be laid with its longitudinal end in a very flat floor covering that is laid on an unfinished floor, in particular on a the sub-floor applied supporting covering, which is in particular screed, are integrated, for example in a tile covering provided on a screed, whereby thanks to its small thickness it can merge into the adjacent floor covering essentially without any vertical offset. The same applies, of course, to the first transverse end.
the floor element also has a correspondingly small vertical thickness over its entire length at its second transverse end, which is opposite the first transverse end in the transverse direction. This makes it possible to integrate the floor element at its two transverse ends and at the first transverse end adjacent to the rest of the floor covering in such a floor covering.
the floor element also has at its second longitudinal end, opposite the first longitudinal end, over its entire transverse extension correspondingly small vertical thickness, so that the floor element can also be integrated into such a floor covering at a distance from a room wall.
the floor element has the same vertical thickness at its first longitudinal end as at its first transverse end and in particular at its second transverse end and in particular at its second longitudinal end.
the maximum thickness over the entire transverse extent at the respective longitudinal end or the maximum thickness over the entire longitudinal extent at the respective transverse end is taken into account.
the floor element also has a gradient of at least 0.7 on its upper side over an area of at least 0.3 m 2 , in particular at least 0.5 m 2 and in particular over at least 70%, in particular at least 80% of the entire surface extent of its upper side %, in particular at least 1%, in particular at least 1.2% towards the drain opening.
the slope is preferably formed over an area of the upper side that is at least 70%, in particular at least 80%, of the entire horizontal extension of the floor element.
the floor element also has a contact area which extends horizontally outside the run-off section and, starting from the first longitudinal end of the floor element, over at least 30%, in particular at least 40%, in particular at least 50%, in particular at least 60% of the length of the floor element in the longitudinal direction towards the drain opening over the entire width of the floor element.
the support area is horizontally completely outside the run-off section.
the floor element preferably consists of the run-off section and the support area.
the support area is preferably designed to support it on an upper side of a screed that is arranged horizontally next to the drain section and runs parallel to the horizontal plane and is provided on the unfinished floor when the shower tray device is in the operating state.
the support area is preferably also designed to be supported on the upper side of the shower tray device when it is in operation, also with regard to another support covering that is arranged horizontally on a subfloor next to the drain section and has an upper side that runs parallel to the horizontal plane.
the floor element When used as intended, the floor element is thus simultaneously supported with its contact area via the supporting covering, in particular screed, on the unfinished floor and extends with its run-off section next to the supporting covering and preferably overlaps horizontally with the unfinished floor, but is offset vertically to it.
the run-off section is thus preferably free above the unfinished floor and therefore not supported on the supporting surface, so that in the operating state explained further functionalities can be provided within the run-off section, while the floor element is supported over a large area on the supporting surface by means of its contact area.
the support covering is generally advantageously arranged according to the invention, preferably exclusively horizontally, outside the run-off section; in one embodiment, it extends but still horizontally overlapping the runoff section but spaced vertically from it so that the runoff section does not overlie it and the support deck is positioned with a vertical portion adjacent to the runoff section such that a vertical portion of the support deck horizontally overlaps the support area and entirely outside of the horizontal extension of the support covering is arranged.
an arrangement of sections or areas or other geometric structures next to each other in the present description defines in particular such an arrangement that the sections or areas or other geometric structures are not arranged overlapping and thus extend outside the other section or Area or other geometric structure are arranged, with a definition of a juxtaposition in a specific direction or plane then of course on the lack of overlap in this direction or plane is turned off.
a juxtaposition here includes in particular an arrangement directly next to each other, unless otherwise stated.
the floor element preferably rests on the described upper side of the described support covering over its entire contact area.
a free space provided between the unfinished floor and the underside of the run-off section horizontally next to the supporting surface and horizontally next to the support area can be used to arrange a drain pot in the free space and to seal it around the drain opening within the run-off section and to connect it to the underside of the floor element, and/or that in the free space a carrier, in particular as explained below, is provided, via which a support surface formed on the underside of the floor element is opposite the Subfloor is supported vertically.
the support section can also be used when the support area is supported on a mounting frame or carrier, which in turn is supported on the unfinished floor and is arranged horizontally next to the drain section and its upper side when the shower tray device is in operation , on which the support area is supported, runs parallel to the horizontal plane.
the support area is designed in particular in such a way that it is designed for said support on the upper side of the mentioned support layer or top side of the mentioned mounting frame when the shower tray device is in the operating state and the top side of the support layer or mounting frame is horizontally directly adjacent to the drain section.
the drainage opening is particularly preferably at least 15%, in particular at least 20%, in particular at least 30%, in particular at least 40% of its entire transverse extent at a distance from at least one transverse end of the floor element, in particular at least from the first transverse end of the floor element. This particularly preferably applies to each transverse end and thus not only to the first transverse end but also to the second transverse end lying opposite the first transverse end in the transverse direction, with the transverse ends delimiting the base element in the transverse direction.
Such a spacing from the respective transverse end is particularly advantageous if the floor element in the operating state extends in the transverse direction over at least 5%, in particular at least 10% of its entire transverse extent in the transverse direction with its contact area, starting from the respective transverse end towards the drain opening and/or in Transverse direction to the respective transverse end extends beyond a carrier explained in more detail below.
the inventors have surprisingly found that the spacing of the drainage opening from the respective horizontal end of the floor element can contribute to the stability of the floor element in a particularly advantageous manner. It must be taken into account here that the drainage opening is in any case already at a considerable distance from the first longitudinal end before the first longitudinal end due to the spacing of the drainage section.
the drainage opening is generally preferably spaced apart from the first longitudinal end by at least 60%, in particular at least 70%, of the longitudinal extent of the base element, ie its length in the longitudinal direction.
the greater robustness of the floor element due to the spacing of the drain opening from the respective horizontal end results from the fact that due to the spacing, a continuously slight gradient can be provided starting from the respective transverse end to the drain opening. This is particularly relevant with regard to the gradient formed from the respective transverse end to the drain opening. Because, of course, the drain opening ends with its upper end at a specific vertical height, which is defined by the minimum required gradient over the distance of the drain opening from the horizontal end furthest away from the drain opening.
the drainage opening is preferably spaced longitudinally from the longitudinal end by a distance which is at least four times, in particular at least five times, its distance in the longitudinal direction from the second longitudinal end.
the spacing of the drainage opening from at least one of the transverse ends, in particular from both transverse ends is particularly advantageous.
the drainage opening preferably extends in each horizontal direction by less than 20%, in particular less than 15%, of the width and/or length of the floor element.
the shower tray device according to the solution described enables a novel realization of a shower floor that is accessible at ground level.
the inventors have recognized that the provision of a flat, large-area floor element is particularly advantageous for this purpose, which has a horizontally large-area support area, via which it can be supported on an upper side of a screed running parallel to the horizontal plane. Due to the small thickness and the flat contact area, the floor element can be integrated very easily into a conventional floor covering, such as a tiled covering. At its first longitudinal end and at its first transverse end, the floor element has a thickness such as that of conventional floor tiles.
the floor element can easily be integrated by a tiler in a tile covering that is applied to a flat supporting covering, such as screed, without having to provide a special supporting structure for this and without having to specifically coordinate the screed with the Floor element must be prepared.
a flat supporting covering such as screed
the floor element itself when it is arranged with its entire contact area on a screed with its upper side parallel to the horizontal plane running across it, forms a gradient towards the drain opening, so that a sufficient proportion of the upper side of the surface element has a directional component in the vertical direction has towards the drain opening.
the invention overcomes this prejudice in that a correspondingly large bearing area encompassed by the floor element is provided for bearing on a screed or other supporting covering and a run-off section encompassed by the floor element is provided next to the bearing area. Because the drain section is provided next to the support area and is therefore not intended to be placed on the supporting surface, the floor element within the run-off section can have a geometry that is decoupled from the support requirement on the supporting surface, for example a greater thickness than within the support area, which ensures sufficient stability and a sufficient gradient the upper side can be realized over the entire horizontal extent of the floor element.
the shower base unit in which the shower base unit is integrated into a room floor comprising an unfinished floor, a supporting covering and in particular a floor covering adjoining the first longitudinal end and the first transverse end, in particular tiled covering, the floor element is only thereby positioned in relation to the unfinished floor supported that it rests with its contact area on the screed and is supported by this on the unfinished floor and possibly also rests with its support surface explained below on the supporting surface of a carrier as explained below and is supported by this on the unfinished floor.
the contact area preferably does not lie directly on the supporting covering but is connected to the floor covering via a connecting layer made of a connecting compound, which is preferably a hardening connecting compound, for example a tile adhesive layer with tile adhesive as the connecting compound, with the connecting layer usually having a layer thickness of less than 10 mm, in particular less than 5 mm, in particular less than 3 mm.
a connecting compound which is preferably a hardening connecting compound, for example a tile adhesive layer with tile adhesive as the connecting compound, with the connecting layer usually having a layer thickness of less than 10 mm, in particular less than 5 mm, in particular less than 3 mm.
the large contact area also ensures that seepage water is effectively prevented from entering between the supporting surface and the floor element.
a further advantage of the shower tray device according to the invention is that new design options are available for the floor element and when the floor element is installed, a person stepping onto the floor element can have a different sense of space. Because the floor element can be supported over a large area on the supporting surface via the contact area, a cavity effect, which easily occurs with conventional shower trays, can be avoided, so that stepping on the floor element is very similar to stepping on a tile or floor element arranged on the supporting surface. similar to another floor covering provided on the supporting covering, which can result in a high-quality stepping sensation. With the shower tray device according to the invention, this can Floor element designed in the manner of a tile and perceived by a user as part of the tile covering.
the floor element can avoid the disadvantages of conventional floor-level showers, which are realized by providing shower channels in a tiled covering as explained above, since on the one hand no special precautionary measures have to be taken when installing the supporting covering, in particular no specific precautions the shower channel has a slope that is turned off, and secondly because the large floor element is easy to clean.
the floor element is particularly preferably manufactured in one piece. Particularly preferably, the floor element has an uninterrupted smooth surface on its upper side.
the shower tray device has a support.
the support has a support surface with which it is arranged in contact with a support surface formed on the underside of the floor element when the shower base device is in operation.
the support surface is formed within the horizontal extent of the run-off section and thus of the run-off section of the floor element and is therefore exclusively arranged outside of the support area.
the supporting surface, with which the carrier bears against the supporting surface for carrying the floor element is arranged exclusively outside of the supporting area.
the carrier has a standing surface for supporting it on a subfloor or for setting it up on a subfloor.
the vertical and the horizontal are in relation to the operating state, which defines a certain arrangement of the components of the shower tray device, and thus in particular the support and the floor element, for all Components of the shower base device defined.
the carrier is thus designed to support the floor element in the operating state on an unfinished floor on which it is supported or set up with its standing surface.
the carrier can stand directly with his standing surface on the unfinished floor or indirectly, for example on an insulating layer applied to the unfinished floor.
the supporting surface can rest directly or indirectly on the supporting surface of the carrier.
the insulating layer is encompassed by the unfinished floor, so that the unfinished floor comprises a load-bearing floor, eg comprising concrete, and an insulating layer lying on the load-bearing floor.
an insulating layer is provided on the unfinished floor in addition to the unfinished floor.
the standing surface of the carrier in the operating state is arranged exclusively outside the horizontal extent of the support area or exclusively horizontally outside and thus next to the support covering.
the carrier is designed to be supported on the unfinished floor by being placed on the screed or other supporting covering or to be set up on the unfinished floor as a result.
the carrier can have, for example, a plate-like laying section for laying on the screed or other supporting covering and a holding section, offset horizontally to the laying section, for supporting the floor element outside of the supporting covering, with the laying section preferably having a thickness of less than 3 mm, in particular less than 2 mm has, so that it can be easily integrated into a tile adhesive covering and no too large corresponding recess on the underside of the floor element needs to be provided, which would be accompanied by a corresponding reduction in thickness of the floor element.
the carrier preferably extends at an intended use of the shower tray device vertically from the unfinished floor to the support surface of the floor element, wherein the carrier can include a stand that can be set up directly on the unfinished floor.
the supporting surface and the bearing surface are preferably congruent and are therefore preferably completely in contact with one another in the operating state.
the contact area lies horizontally outside of the support surface and thus in the operating state of the shower tray device outside of the horizontal area of the shower tray device in which the carrier rests with its supporting surface on the floor element in order to carry the floor element as intended on an unfinished floor on which it can be placed with its standing surface is.
the carrier bears at least part of the weight force exerted by the floor element vertically in the direction of the unfinished floor and correspondingly also at least part of the weight force of a person who is standing on the floor element when the shower tray device is used as intended.
the carrier is preferably designed to transfer a vertical weight force of at least 200 N from the supporting surface to the standing surface without deformation via the interaction of the supporting surface and supporting surface, so that it can hold a corresponding weight resting on its supporting surface over a subfloor without deforming , on which it is set up with its base.
the support area is preferably arranged horizontally completely outside the carrier, at least completely outside the support surface and the supporting surface, and in particular in the operating state for support on an upper side of a top surface that is arranged horizontally next to the carrier in the operating state of the shower tray device and runs parallel to the horizontal plane screed or other intended for the subfloor Supporting covering formed with a simultaneous support of the carrier on the unfinished floor.
the floor element When used as intended, the floor element is thus simultaneously supported with its contact area via the supporting covering, in particular screed, on the subfloor and with its support surface via the carrier on the subfloor, whereby thanks to its above-mentioned suitability it can of course also be used in one application , in which the support area is supported on a mounting frame, which in turn is supported on the unfinished floor and is arranged horizontally next to the support when the shower tray device is in operation and whose upper side, on which the support area is supported, runs parallel to the horizontal plane.
the carrier can also be designed in such a way that it carries the floor element alone, without the floor element having to rest with a contact area on the supporting covering.
the support area is designed in particular in such a way that it is designed for said support on the upper side of the mentioned support layer or top side of the mentioned mounting frame when the shower tray device is in the operating state and the top side of the support layer or mounting frame is horizontally directly adjacent to the support.
the support area is designed for support on the upper side of the supporting surface or mounting frame, which is vertically at the same height as at least a section of the supporting surface, in particular the entire supporting surface of the carrier.
a flat, large-area floor element is particularly advantageous which, on the one hand, has a horizontally large-area contact area over which it rests on an upper side of a supporting covering running parallel to the horizontal plane can be supported, and on the other hand has a support surface outside the support area, via which it can be supported on a carrier.
a correspondingly large bearing area for bearing on a support covering is provided and a support surface for supporting on the carrier of the shower tray device is provided on the floor element.
a targeted support of the floor element via the support on the unfinished floor can be realized in addition to the standard laid support covering, and at the level of the support surface the floor element can be designed in any geometric configuration in coordination with the intended support , whereby its sufficient stability can be obtained.
the provision of the described embodiment, in which the shower tray device has a support has proven particularly useful in the case of very large floor elements whose horizontal extent is at least 1 m 2 and/or whose drain section has a horizontal extent of at least 0.1 m 2 , in particular at least 0. 2 m 2 has been found to be particularly advantageous.
the carrier has a carrying element and at least one standing element.
the stand element can be designed as a stand, for example.
the support element forms the support surface of the carrier, and the at least one base element forms the base of the Carrier and is designed to be supported on the unfinished floor and for holding the support element spaced from the unfinished floor.
the support element is generally preferably designed in one piece, ie produced directly as a one-piece coherent component.
the carrier comprises several mounting brackets as stand elements, which have a laying section for laying on the bearing covering and a holding section offset vertically and horizontally thereto, on which the bearing element can be laid and which thus forms a load surface for carrying the bearing element.
the laying-on section particularly preferably has a vertical thickness of less than 2 mm.
the brackets can, for example, have a step-like course, with the laying-on section being connected to the holding section via a vertical step. With a corresponding implementation of the carrier, the standing element is thus supported via the supporting covering on the unfinished floor.
the support element of the support is designed to correspond to the stand elements, so that it is held at a vertical distance from the unfinished floor via the stand elements, in the exemplary embodiment described by placing it on the holding sections of the stand elements designed as holding brackets, so that, for example, there is still a building-side drain pipe between the support element and the unfinished floor and/or a drain pan of the shower tray device can be arranged and/or the underside of the floor element can run vertically below the supporting covering.
at least some of the stand elements, in particular all stand elements are designed as feet that can be set up directly on the subfloor with a foot section and are thus supported directly on the subfloor and not supported on the subfloor by means of the supporting covering.
Such feet can, for example, a Have holding section, via which they are connected to the support element.
This connection of the feet to the support element allows the support element to be held at a corresponding vertical distance from the unfinished floor by the feet.
at least some of the stand elements, in particular all of the stand elements, of the support are connected to the support element within the edge region of the support element, which is explained in more detail below, and which forms at least a section of the support surface of the support, resulting in particularly high stability of the support surface due to direct support by means of the stand elements can be guaranteed.
the feet, in particular with their foot sections form the standing surface of the carrier, with the standing surface overlapping horizontally with the support surface.
the support preferably has a plurality of support elements designed as feet, which are arranged horizontally spaced apart from one another at a point on the support element that is assigned to them. All of the stand elements of the carrier are preferably designed as such stand feet.
the feet are preferably each arranged in a horizontal end section of the support element, in particular arranged in the edge region explained here.
the horizontal end section of the support element is a section of the support element that forms an end of the support element in a specific horizontal direction and extends from this end in the specific horizontal direction by less than 20%, in particular less than 15%, in particular less than 10% of the extent, ie the length, of the support member in that particular horizontal direction.
Each of the feet is preferably designed to be adjustable in height for setting a spacing of the support element from the unfinished floor at precisely the point on the support element which is assigned to the respective base and at which the respective base is arranged on the support element. Due to the height adjustability of the feet, their vertical length can be adjusted between the foot section with which they are set up on the unfinished floor and the holding section with which they are connected to the support element. Correspondingly, the vertical adjustability of the support element relative to the unfinished floor is ensured by the height adjustability, while the support element is positioned horizontally to the unfinished floor by each of the feet with its location assigned to the respective foot.
each foot is connected to the support element at its assigned point and is connected to the unfinished floor at a specific point, in particular is set up on the unfinished floor.
each base has a base section with which it can be set up on the unfinished floor.
each base has a holding section by which it is held on the support element.
a passage for a fastening means is preferably provided in the foot section, with which the foot can be fixed in position on the unfinished floor.
the base can be fixed in position on the unfinished floor by means of a screw and dowel connection.
the feet of the support are generally preferably first fixed to the unfinished floor and the support element is then aligned vertically, in particular by actuation of the feet.
the feet are particularly preferred in each case from their Height-adjustable top, in particular from the top of the carrier.
the feet are preferably designed in such a way that they can each be brought into different length states, in which they each have a different vertical length.
each of the feet has a defined vertical extension length between its holding section and its foot section, and this extension length is different in each length state, so that changing the length state of the base changes the distance of the support element at the horizontal point is generated, on which the base is arranged or attached.
the feet are preferably designed in such a way that they maintain their vertical length in any length condition under a vertical compressive load with a force of 100 N, in particular with a force of 200 N.
the feet are designed in such a way that they retain their vertical length in any length condition under a vertical tensile load with a force of 50 N, in particular 100 N. This can be ensured, for example, by providing a threaded connection within each base or a detachable latching connection within each base.
a vertical compressive load is such a force load that works towards a reduction in the vertical length of the feet
a vertical tensile load is such a force load that works towards an increase in the vertical length of the feet.
the feet By allowing the feet to their adjusted vertical Keeping the length both in the case of pressure and tensile loads can, on the one hand, make it possible to carry a vertical load-bearing capacity when the load-bearing element is loaded from above via the feet, which results in the pressure load mentioned; Supporting covering, in particular screed, after installation of the carrier on the unfinished floor and attachment of the feet to the unfinished floor, whereby the said tensile load can arise, the support element floats.
the feet each comprise a plurality of parts, in particular a foot element for setting up on the unfinished floor, a holding element for holding on the support element and a connecting element for connecting the foot element to the holding element.
the foot element can, for example, form the explained foot section and the holding element the explained holding section of the respective base.
the base is fixed to the support element via its holding section.
the holding element which forms the holding section, can be provided integrally in the support element or can be a component separate from the support element.
the supporting element and the standing element can be partially integrated into one another.
at least part of the standing element is a component that is manufactured separately from the supporting element, so that the supporting element and standing element are designed as separate components that are manufactured at least partially independently of one another.
at least foot element and connecting element are preferably components that are produced separately from the supporting element, in particular separate components that can be detached from the supporting element.
the standing element and the supporting element are components that are completely separate from one another. are preferred the different length states of the respective base adjustable in that at least some of the parts of the base are moved towards each other.
the length states can preferably be adjusted by moving the connecting element relative to the holding element and/or relative to the foot element.
the connecting element is designed as a threaded rod, the length states being adjustable by rotating the connecting element relative to the base element and/or relative to the holding element.
the foot element and/or holding element preferably have a thread that corresponds to the threaded rod, so that the different length states can be adjusted by turning the threaded rod.
only one of the foot element or holding element, in particular the holding element has such a corresponding thread
the other of the foot element and holding element only has a pivot bearing at a single vertical height for supporting the threaded rod outside of its thread.
the shower tray device has a peripheral frame with a horizontal extension, with the drain section, and thus the support surface preferably encompassed by the drain section, of the floor element being arranged completely within the horizontal extension of the frame in the operating state and the frame being completely below the frame in the operating state Floor element is arranged.
the frame thus serves to define a horizontal section in which the run-off section for realizing the operating state is arranged.
the frame can thus serve as a placeholder during the application of a supporting covering, such as screed, on the unfinished floor, since the frame reliably provides sufficient leaves horizontal space free for the drain section.
the frame is surrounded or formed by the carrier, in particular by the support element.
the frame is formed by a frame element whose vertical height can be adjusted, in particular cut to size.
Vertical height adjustability may be provided through expert choice of a suitable material, such as choosing a cuttable material and/or providing adjustability geometries, such as break lines.
the adaptability is to be provided in such a way that the vertical height can be easily changed by a fitter on a construction site using conventional hand tools after the frame element has been fixed to a subfloor and, in particular, a supporting covering has been applied around the frame element to the subfloor,
a supporting covering has been applied around the frame element to the subfloor
the frame element can be shortened, starting from a state in which the supporting covering around the frame element has been applied to the subfloor and the frame element protrudes vertically over the subfloor, so that it no longer extends vertically over the unfinished floor protrudes.
the frame element can be provided in addition to the carrier or supporting element and only serve as a placeholder during the application of the supporting covering.
the frame element can be made of plastic, for example TPE foam.
the frame element can be designed, for example, in the manner of a cuboid, in particular in the manner of an open box, so that it can have sufficient robustness even if it is made of a soft, cuttable material, so that the supporting covering can be applied right up to the frame element, without deforming the frame member, with the design of the frame element in the manner of a box that is open vertically at the top, the ability to insert the support element into the frame element can be particularly beneficial.
the frame in the operating state preferably does not protrude vertically beyond the supporting lining, and thus ends vertically below the upper side of the supporting lining or ends vertically flush with it.
the frame preferably has a projection arrangement on at least one of its outer sides below the upper side of the carrier for hooking to the support covering, in particular on at least the outer side, which in the operating state points in the same direction as the first longitudinal end of the floor element, and in particular also at least on the outside facing in the same direction as the first transverse end of the floor member in the operative condition.
the outsides are horizontal outsides.
the support element has an edge area and a central area lying horizontally within the edge area and surrounded by the edge area.
the edge area can form the frame explained above.
the edge area forms with at least a section of the wing, in particular the entire wing, on its upper side.
the edge area protrudes vertically over the center area.
the floor element can preferably be placed with its support surface on the edge area and within the edge area, namely within the horizontal extent of the central area, extend vertically downward beyond the edge area. A considerable thickness of the floor element can thus be provided within the central region, which can be particularly advantageous for the stability of the floor element.
the edge area and the central area are generally preferably connected to one another in one piece.
the edge area merges into the central area via a step, ie via a vertical step.
the edge area particularly preferably has a width of at least 20 mm, in particular at least 30 mm, with which it runs around the central area.
the width is thus a width in the horizontal direction, and the width is thus a ring width with which the edge area encloses the central area like a ring.
the upper side of the edge region preferably lies in one plane over at least 50%, in particular at least 70%, in particular at least 80%, in particular at least 90% of its entire horizontal extension.

the edge area preferably has a width of at least 20 mm, in particular at least 30 mm, over at least 50%, in particular at least 70%, in particular at least 80% of its circumferential length, with which it runs around the central area; the edge area preferably runs around the central area without interruption with such a width.
a configuration of the edge area as the central area with a corresponding Width all around has several advantages. On the one hand, this can ensure particularly good support of the floor element by the edge area. In the operating state, the floor element preferably rests on the edge area over at least 50%, in particular at least 80%, in particular 100% of its horizontal extent.
the edge area can ensure a particularly easy to implement and reliably sealing connection of a sealing collar to the support element and in particular to a drain pan of the shower tray device, which is connected to the support element in a fluid-conducting manner.
the shower tray device has a sealing collar which, closed around the central area, is sealingly connected to the edge area and which, closed around the central area, protrudes horizontally by at least 20 mm, in particular at least 30 mm, beyond the edge area.
the sealing sleeve can be a coherent component which can be permanently fastened to the support element on several sides or which has a fastening device corresponding to the support element, or the sealing sleeve can be implemented by subsequently applied sealing strips which, for example, can be removed after the support has been set up on the unfinished floor and Application of the support covering to the edge region with the support covering, and for example a wall adjoining a horizontal end, for example the second longitudinal end, can be glued in an overlapping manner.
a fleece layer is provided on the upper side of the edge area, running horizontally around it, for gluing on a sealing tape. Such a fleece layer is particularly advantageous in order to ensure a reliable sealing connection of a sealing tape to the edge area and thus to the wearer.
the fleece layer has preferably has a width of at least 20 mm, in particular at least 30 mm, over which it is horizontally closed all the way around and is therefore designed as a “non-woven layer ring”.
the fleece layer runs horizontally closed around the drain opening and/or around the inlet of the drain pan.
a further fleece layer or other reinforcement layer is particularly preferably provided on the underside of the support element within the same horizontal region over which the fleece layer extends on the upper side.
the additional fleece layer or other reinforcing layer thus extends within the edge area of the support element, based on its horizontal extension.
the further non-woven layer or other reinforcement layer can ensure that the support element is not subsequently influenced during its production process by the application of the non-woven layer provided on the upper side.
the inventors have recognized that by providing a fleece layer on the upper side and another fleece layer or other reinforcement layer during the production process of the support element, it can be particularly reliably ensured that the support element has a determinate shape after the production process has ended. Because the sealing sleeve is connected to the edge area in a sealing manner and also protrudes horizontally around the edge area, i.e. it extends on the horizontal side of the edge area facing away from the central area, the sealing sleeve can be connected particularly easily to a supporting layer or a supporting layer adjoining the supporting element. connect an adjacent wall sealingly, so that water ingress at the transition from the supporting layer or an adjacent wall to the supporting element can be effectively prevented.
the edge region in the operating state is at least 50 mm, in particular at least 10 cm, from at least one horizontal end of the floor element, in particular at least from the first longitudinal end and in particular from the first transverse end, in particular from each transverse end of the floor element.
the edge region is particularly preferably spaced at least from the first longitudinal end of the floor element by at least 10 cm, in particular at least 30 cm, in particular at least 50 cm. The spacing of the edge area can ensure, on the one hand, that the floor element with the contact area rests over a large area on the support covering in the operating state.
the overall length of the sealing connection between the support element or carrier and the adjacent floor covering can be kept as short as possible.
a sealing line is not required over the entire length of the edge of the floor element, but it is sufficient that the seal is only implemented at the transition from the carrier to the floor covering and thus from the edge area to the floor covering.
the support element is preferably made of plastic, in particular by means of an injection molding process or made of plastic foam, in particular PE foam.
the support element can be manufactured particularly cost-effectively and yet sufficiently robustly.
the standing elements of the carrier are also made of plastic, in particular by means of an injection molding process.
the support element has a vertical thickness of at least 50 mm over at least 20%, in particular at least 30%, in particular at least 50%, in particular at least 70% of its entire horizontal extent, with which it extends between its longitudinal and transverse ends. in particular at least 60 mm. This thickness can be formed, for example, by a rib structure or by solid material.
the support element preferably has a stepped profile on its upper side and/or on its underside, so that despite the provision of a correspondingly large thickness, it leaves sufficient space for further components of the shower tray device, for example for a drain pan.

the absolute vertical lower end is the lower end of the respective tenth of the longitudinal extension, which forms the absolute lower end of the floor element over the entire flat extension of the tenth, and thus over the entire width of the floor element within the respective tenth of the longitudinal extension.
Said tenths of the longitudinal extent ie the first, third and in particular fourth and in particular fifth tenths, preferably all lie within the horizontal extent of the support area.
the support area can, of course, have a certain contouring on its underside, as is usual with tiles, for example, so that it can be better connected to the supporting covering by means of a tile adhesive.
the floor element can also have, for example, a sealing sleeve which is connected to the support area in a watertight manner or has a fluid-carrying connection to the drainage opening, which forms the underside of the floor element and which can entail a certain contouring of the underside of the floor element.
a sealing sleeve which is connected to the support area in a watertight manner or has a fluid-carrying connection to the drainage opening, which forms the underside of the floor element and which can entail a certain contouring of the underside of the floor element.
the floor element can be supported sufficiently continuously on the screed over its longitudinal extension, so that the floor element can be reliably placed on a horizontal plane with its upper side extending screed can be supported non-destructively, in particular via a tile adhesive layer that has a maximum vertical thickness of 5 mm.
the floor element can easily be integrated as a single component in a floor covering, in particular a tiled covering.
an absolute vertical upper end of a transverse center of the floor element is in the first longitudinal end forming the first tenth of the longitudinal extension of the floor element with a vertical offset to an absolute vertical upper end of the transverse center in the fourth tenth and/or in the fifth tenth of the longitudinal extension of the floor member which is at least twice the offset by which the absolute vertical bottom end of the floor member formed within the first tenth is spaced from the absolute vertical bottom end of the floor member formed within the fourth and/or fifth tenth.
the tenths it is generally based on the fact that the first tenth forms the first longitudinal end and the further tenths each follow from the first longitudinal end at an increasing distance in the longitudinal direction according to their numbering to the first tenth.
the transverse center in each case designates the center of the floor element along the transverse direction.
a height gradient of the transverse center is thus realized on the top of the floor element, which provides a sufficient gradient towards the drain opening, since there is a corresponding vertical offset between the vertical height of the transverse center in the different tenths of the longitudinal extent, while on the underside of the Offset is kept low, so that the floor element can be placed on a conventional flat supporting surface and can form the gradient integrally on its upper side.
the offset between the in the first longitudinal end forming the first tenth of the longitudinal extent of the floor element, to the absolute vertical lower end of the floor element formed in the third tenth of the longitudinal extent of the floor element less than a quarter of the offset between that formed in the first tenth of the longitudinal extent of the floor element absolute vertical lower end of the floor element to the absolute vertical lower end of the floor element formed in the sixth tenth and/or seventh tenth and/or eighth tenth of the longitudinal extent of the floor element.
the offset between the absolute vertical lower end of the floor element formed in the first tenth of the longitudinal extent of the floor element and the absolute vertical lower end of the floor element formed in the fourth tenth of the longitudinal extent of the floor element is less than one fifth of the offset between the first tenth of the longitudinal extent of the floor element formed absolute vertical lower end of the floor element to the eighth tenth of the longitudinal extension of the floor element formed absolute vertical lower end of the floor element.
the vertical offset formed between the absolute vertical lower ends in the first tenth and in the third tenth and/or in the first tenth and in the fourth tenth can be less than 3 mm, in particular less than 2 mm, in particular less than 1 mm, while the vertical offset between the absolute vertical lower ends, which are formed in the first tenth and in the sixth tenth and/or in the first tenth and in the eighth tenth, is at least 5 mm, in particular at least 7 mm, in particular at least 10 mm amounts to.
the offset can be kept particularly small at the level of the contact area, which preferably extends over the specified first and third and in particular fourth tenths, while there is then a significant offset on the underside.
the vertical thickness of the floor element can increase significantly along the longitudinal direction up to the drain opening outside of the support area. In this way, a sufficient thickness and thus stability of the floor element outside of the support area can be ensured, while the floor element outside of the support area continues to form a gradient towards the drainage opening on its upper side.
the support area extends horizontally outside the run-off section, in particular outside the support surface, starting from the first transverse end of the floor element over at least 10%, in particular at least 20%, in particular at least 30% of the width of the floor element over the entire length of the floor element in the Transverse direction towards the drain opening.
the support area also extends horizontally outside the run-off section, in particular outside the support surface, starting from the second transverse end of the floor element, which is opposite the first transverse end in the transverse direction, over at least 10%, in particular over at least 20% of the width of the floor element over the entire length of the Floor element in the transverse direction towards the drain opening.
the floor element with the support area can also over a considerable area of its transverse extent at the first and in particular at the second transverse end on the said horizontal flat surface of said screed as explained above.
a particularly simple integration of the floor element into a floor structure can also be made possible at the transverse end or ends, and other advantages explained above with reference to the first longitudinal end can also be implemented, for example inhibiting the ingress of seepage water and avoiding a cavity Effect when entering the floor element.
the contact area is preferably only formed on the first longitudinal end and the first transverse end and in particular the second transverse end of the floor element, but not within one of the two transverse ends at a distance of at least 20% of the width in the transverse direction, on the area opposite the first longitudinal end in the longitudinal direction second longitudinal end of the floor element.

the provision of the drain opening in the longitudinal end area mentioned is advantageous for connection to a drain and for shower comfort, since the drain opening is provided at the edge and therefore not within a commonly used standing area of the floor element.
the drain opening in the The longitudinal end area mentioned is made possible in a particularly advantageous manner by the particularly preferred embodiment, in which on the one hand a support area extending towards the second longitudinal end is provided on the first longitudinal end opposite the second longitudinal end and on the other hand a support is provided outside the support area, the geometry of which specifically the geometry of the floor element is coordinated so that the floor element can extend over the carrier with a considerable longitudinal extension and considerable vertical thickness.
the drainage opening it is particularly preferable for the drainage opening to be arranged within the horizontal extension of the carrier.
the carrier can be configured in any way in order to fulfill its carrying function.
the carrier has a plurality of feet spaced apart from one another, which are arranged distributed horizontally around the drain opening.
the carrier has a housing with a housing wall that encloses the drain opening.
the housing wall is closed around the drain opening and/or is designed to form several feet.
the housing wall preferably forms the supporting surface on its upper side and the standing surface on its underside.
the carrier preferably comprises a drain pot which has an inlet connected to the drain opening to carry water and an outlet which can be connected to a waste water line and which is connected to the support surface when the shower tray device is in operation, preferably in one piece.
the carrier can have a housing with a housing wall, the housing integrally forming the drain pan.
the carrier can have feet that are connected to the drain pan in the operating state, which is a component that is separate from the feet is trained.
the underside of the floor member has a first portion formed by the support area and a second portion longitudinally disposed between the drain opening and the support area, the second portion being offset vertically downward relative to the first portion .
the second section is particularly preferably offset vertically downwards by at least 3 mm, in particular by at least 5 mm, relative to the first section.
the second section is preferably formed by the drain section.
the underside has a vertical offset outside of the support area, with which it transitions from the first section into the second section in relation to the longitudinal direction.
the projection can be designed in a step-like manner, for example, so that the underside forms a vertical step downwards during the transition from the first section to the second section.
the first section can merge into the second section via a contour that has a component running in the vertical direction.
the provision of a first section and a second section of the underside makes it possible to provide a greater thickness of the floor element within the horizontal extension of the second section, which is thus formed outside of the support area, whereby the floor element is sufficiently robust with the formation of a gradient up to the drain opening can.
the preferably provided support surface of the floor element particularly preferably extends at least in sections between the first and the second section of the underside of the floor element and/or within the second section of the underside.
the top within the first Section has a lower gradient along the longitudinal direction than in the second section.
Slope along the longitudinal direction refers to the slope of the upper side along the longitudinal direction with respect to the vertical.
the floor element particularly preferably has a greater vertical thickness in the second section than in the first section.
the second portion is further formed transversely between the first portion and the drain opening.
the underside preferably transitions from the first section into the second section with the stated offset both with respect to the longitudinal direction and with respect to the transverse direction.
the second section encloses the drainage opening horizontally, preferably continuously closed, and preferably the underside with the mentioned step, circumferentially surrounding the drainage opening, preferably continuously closed, transitions from the first section into the second section.
the upper side preferably has a smaller gradient along the transverse direction within the first section than in the second section.
the underside of the floor element has a third section arranged between the first section and the second section of the underside of the floor element, which is at the same vertical height as the first section and in particular forms at least a section of the support surface that is preferably provided, in particular forms the entire support surface.

the support surface of the floor element generally preferably extends at least in sections at the same vertical height as the underside of the floor element in the first section of the underside of the floor element formed by the bearing area.
the installation of the floor element on a room floor or a support covering provided on the room floor can be particularly favored by means of the carrier.
the second section of the underside of the floor element has a smaller horizontal extent than the central area of the support element, so that the floor element can be displaced horizontally relative to the carrier or to the support element of the carrier, while its third section rests on the edge area and thus at least one Section of the wing or the wing rests as a whole. Since the second section of the underside of the floor element is vertically offset from the first and the third section, the second section thus protrudes vertically downwards over the edge area or the bearing surface formed by the edge area or the section of the bearing surface formed by the edge area .
the floor element when it rests with its third section on the edge area, it can only be displaced horizontally relative to the support element until it rests against the edge area with the vertical step formed between the first and second or third and second section.
the second section since the second section has a smaller horizontal extent than the central area, there is a certain amount of play between this step delimiting the second section of the underside and the edge area, so that a certain displaceability of the floor element relative to the support element is made possible.
This is a readjustability of allows horizontal position of the floor element when it is placed on a carrier that is anchored or fixed in position on the unfinished floor.
the offset explained is preferably provided between the third section and the second section, whereas the first section and the third section run at the same vertical height.
the third section encloses the second section horizontally and continuously closed all the way around.

the floor element has a stiffening structure, for example a reinforcement and/or a fiber insert, at the transition between the first and the second section.
the third section explained above is particularly preferably provided between the first section and the second section, with the floor element having the stiffening structure at the transition between the third section and the second section.
the stiffening structure is a structure that increases the breaking strength of the floor element.
the floor element can essentially be made of plastic, for example a polymer or PU foam, or the floor element can essentially be designed as a cast mineral tile.
the floor element thus essentially consists of a base material, which is responsible in particular for the look and feel of the floor element, especially on its upper side.
the stiffening structure is embedded in the base material.
the stiffening structure can include reinforcement with metal wires, in particular a metal mesh.
the stiffening structure can include glass fibers.
the stiffening structure is preferably only provided locally and not over the entire horizontal extent of the floor element at the transition between the first and second section. The inventors have recognized that precisely in the transition between the first and second section, in particular between the third and second section, the design of the floor element results in only a small thickness of the floor element, so that the floor element has a higher susceptibility to breakage in this area in particular , whereas precisely because of the vertical offset between the first and second section and the associated possible vertical thickening of the second section, a higher breaking strength can already be given in the second section because of the greater thickness.
the stiffening structure particularly preferably extends over the entire horizontal area of the floor element in which the floor element has its minimum vertical thickness. In one embodiment, the stiffening structure extends over the entire horizontal extension of the floor element.

the gradient formed on the upper side is at least predominant within the support area along the longitudinal direction from the first longitudinal end to the drain opening and in particular along the transverse direction from the first transverse end to the drain opening and in particular along the transverse direction from the second transverse end to the drain opening. in particular formed entirely by reducing the vertical thickness of the floor element within the area over which the slope is formed, starting from the vertical thickness provided at the first longitudinal end, first transverse end and second transverse end, respectively.
the gradient is thus largely formed by reducing the vertical thickness. Since the slope is formed by reducing the vertical thickness provided within the horizontal extension of the named surface, the underside of the floor element can have a constant height profile within the support area over the longitudinal extension and in particular transverse extension of the support area in its vertical height.
the floor element has a greater vertical thickness at its second longitudinal end, which is opposite the first longitudinal end, than at its first longitudinal end.
the floor element can be particularly robust at its second longitudinal end, and when the floor element is arranged with its second longitudinal end on a wall, this can have the effect that as little water as possible used for showering reaches the wall.
the inventors have recognized that at the second longitudinal end, but outside of the transverse ends adjacent to the second longitudinal end, when installing the floor element with the second longitudinal end on a wall does not need to be placed on the thickness of conventional tiles.
the upper side has a greater mean slope in the longitudinal direction from the second longitudinal end to the drain opening than from the first longitudinal end to the drain opening.

the inlet In the operating state, the inlet carries water, in particular in alignment with the outlet opening of the floor element, and is arranged under the floor element for receiving water flowing off vertically downwards through the outlet opening.
a seal surrounding the drain opening is provided, which ensures sealing of the base element against the drain pot surrounding the drain opening in the operating state.
the inlet to the drain opening is arranged in the operating state in such a way that water that enters the drain opening from the top of the floor element is guided by it to the inlet of the drain pot, which is arranged on the underside of the floor element.
the drain is designed to be connected to a drain pipe on the building side, preferably for draining water into the drain pipe, which has reached the drain pot via the drain opening and the inlet connected to it in the operating state.
the drain pot particularly preferably has an odor barrier between the inlet and the outlet.
the drain pan is particularly preferably arranged horizontally exclusively within the drain section of the floor element.
the drain pot is preferably fastened to the underside of the base element in a continuous, closed manner around the drain opening in a sealing manner.
the shower tray device has a connection unit which is arranged on the underside of the base element and which, in the operating state, connects the drain opening to the drain pan in a fluid-conducting manner in such a way that any water that emerges from the drain opening on the underside of the base element flows to the inlet of the drain pan to be led.
the connection unit is thus designed to ensure that water which emerges from the drain opening on the underside of the floor element is guided to the inlet of the drain pan.
the connection unit is formed by the carrier or at least in the operating state is attached to the carrier independently of the floor element, in particular fixed in a fixed position.
the connecting unit is formed by the support element of the carrier explained or is attached to the support element of the carrier, in particular fixed in a fixed position, at least in the operating state independently of the base element.
the connecting unit preferably extends predominantly, in particular exclusively, on the underside of the floor element.
the connecting unit preferably encloses the drainage opening circumferentially closed or is connected to the drainage opening in an uninterrupted sealing manner on a circumferential inner side thereof.
the connection unit and the floor element are designed to correspond to one another in such a way that the water flow is ensured over a horizontal displacement area of the floor element relative to the connection unit.

the absolute vertical upper end of the transverse center of the floor element 2, which is formed in the first tenth of the longitudinal extent of the floor element 2 starting from the first longitudinal end 22, is formed here by the vertical height of the edge 24, is significantly offset from the absolute vertical upper end formed in the third tenth of the length of the floor member, and more of the absolute vertical top formed in the fourth tenth, and more of that formed in the fifth tenth of the length.
this design of the contact area of the floor element 2 means that the floor element 2 is placed with its contact area like a tile on a screed running in the horizontal plane with its upper side and is fastened to it with tile adhesive can.
the vertical thickness of the floor element 2 in its transverse center continues to decrease due to the formation of the gradient on the upper side 21 .
a critical thickness of the floor element 2 is reached from a certain distance, in which a sufficient stability of the floor element 2 is no longer guaranteed.
this thickness is not reached, but before the thickness of the floor element 2 is reduced too much, the support surface of the floor element 2 is formed, with which it rests on the supporting surface 33 of the carrier 3 in the operating state.
the floor element 2 With an increase in its vertical thickness, the floor element 2 has an offset on its underside, so that a vertical offset between the absolute vertical lower end of the floor element 2 formed in the first tenth of the longitudinal extension of the floor element 2, in relation to the first longitudinal end 22, and the im seventh tenth of the longitudinal extension of the floor element 2 formed absolute vertical lower end of the floor element 2 is formed.
the bottom element 2 forms a first section 201 on its underside, which is formed by the support area, and a second section 202, which is arranged in the longitudinal direction X between the drain opening 20 and the support area, the second section 202 relative to the first Section 201 is offset vertically downwards and the underside outside of the contact area has a vertical jump downwards, with which it merges from the first section 201 into the second section 202.
the jump starting from the support surface in the longitudinal direction X to the housing interior of the housing 31 of the Carrier 3 is formed.
the floor element 2 has a greater vertical thickness at the second longitudinal end opposite the first longitudinal end 22 than at its first longitudinal end 22 and correspondingly runs with a greater incline towards the drain opening 20 . Also is in figure 2 It can be seen that the drainage opening 20 is arranged in a longitudinal end area of the floor element 2, which forms the second longitudinal end and which extends over less than 30% of the length of the floor element 2 in the longitudinal direction X, which is generally advantageous according to the invention.
the support surface of the floor element 2 is formed exclusively in a longitudinal end area of the floor element 2, which forms the second longitudinal end and extends over less than 50%, in this case less than 40%, of the length of the floor element 2, starting from the second Longitudinal end extends in the longitudinal direction X, which is also advantageous according to the invention. Due to the special design of the embodiment described, it is possible to arrange the floor element 2 with its second longitudinal end on a wall, on which the carrier 3 is then also arranged.
the thicker second longitudinal end can prevent water from entering between the wall and the floor element 2 particularly well, and the arrangement of the carrier 3 in the longitudinal end area mentioned allows the carrier 3 to be positioned very close to the wall and thus very close to the wall of the floor element 2 support against a subfloor on which he is placed with his footprint 34.
the carrier 3 there is no need for a screed strip between the wall and the support 3, which is usually difficult to implement and there is a risk of damage.
a section of the supporting surface 33 of the carrier 3 and a section of the supporting surface of the floor element 2 are arranged in a longitudinal end region of the floor element 2, which, starting from the second longitudinal end, extends by less than 10%, in particular by less than 5% % of the length of the floor element 2 towards the first longitudinal end 22, this section of the supporting surface 33 or supporting surface generally preferably forms at least 10%, in particular at least 20% of the supporting surface 33 or supporting surface.

the underside of the floor element 2 comprises a first section, which forms the support area of the floor element, and a second section 202, which is arranged in the longitudinal direction and in the transverse direction between the drainage opening 20 and the support area or the first section 201, and a third section 203 , which is arranged at least on two transverse sides and one longitudinal side of the drain opening 20 between the first and the second section 201, 202.
the second portion 202 of the underside is within this second portion 202 relative to the first due to a greater vertical thickness of the floor member Section 201 offset vertically downwards.
the base element 2 protrudes with the second section 202 of its underside into the trough formed by the central region 312 of the support element 301, while the base element 2 with a first section 201 adjoining, at the same vertical height directly in this transitioning third section 203 of its underside on the bearing surface of the carrier 3 formed by the edge region 311 and is thereby supported on the carrier 3.
the second section 202 of the underside of the floor element 2 has a smaller horizontal extent than the middle region 312 of the support element 301 .
the shower tray device 1 has several feet 32 as standing elements.
the feet each comprise a plurality of parts, in the present case a foot element 321, a connecting element 323 and a holding element 322.
the holding element 322 is designed as a sleeve with an internal thread. In the embodiment described, the holding element 322 is pressed into the supporting element 301 .
the holding element 322 can be integrated in the support element 3 .
the connecting element 323 is designed as a threaded rod with an external thread, which is rotatably mounted in the foot element 321 in a constant vertical position.
the interaction of foot element 321, connecting element 323 and holding element 322 is particularly off Figure 4D apparent.
the foot elements 321 each have a passage for a screw 324 which, in the installed state, ie when the carrier 3 has been fastened to the unfinished floor 5, is screwed into a dowel which is provided in the unfinished floor 5.
the support element 301 On its horizontally circumferential outer side, the support element 301 also has a projection arrangement 313 below its upper side and thus below the support surface formed by the edge region 311 .
This projection arrangement 313 can advantageously engage in a supporting covering, in particular screed 6, which is applied to the unfinished floor 5 according to an embodiment of the method according to the invention after the carrier 3 has been attached to the unfinished floor 5 beforehand.
a screed 6 is in Figure 4D shown.
the shower tray device 1 also has a drain pot 35 and a connecting unit 36, through which the drain opening 20 of the base element 2 is fluid-carrying connected to the drain pot 35, ie the inlet of the drain top.

a ring seal 363 is fixed in a fixed position on the floor element 2, closed horizontally around the drain opening 20, as shown in Figure 4C is shown.
the sealing connection between the base element 2 and the flange 362 is already provided by the weight of the base element in conjunction with its effect on the ring seal 363 .
FIG 5 including the Figures 5A and 5B are shown in various schematic representations of principles of components of a further embodiment of a shower tray device 1 according to the invention.
the embodiment according to figure 5 differs from the embodiment according to figure 4 essentially in that in the embodiment according to figure 5 are provided as stand elements of the carrier 3 bracket 37 and that the frame of the shower tray device 1 is not, as in the embodiment according to figure 4 , is provided by the supporting element 301 of the carrier 3, but by a separate frame element 8. Only the differences in the embodiment according to FIG figure 5 with regard to the embodiment according to figure 4 received.
a frame element 8 is provided that is cuboid, in this case designed in the manner of an open box and is made of a soft plastic, in this case TPE.
the frame element 8 is first placed on the unfinished floor 5, as is shown in Figure 5A is shown.
the frame element 8 has such a geometric extent that, in principle, the support element 301 can be accommodated horizontally by the frame element 8, as is shown in Figure 5A is shown for the sake of explanation.
the Figures 5A and 5B show a section through the components shown in the respective figures, the section passing through a plane defined by the longitudinal and vertical directions.
the support element 301 is held at a vertical distance from the unfinished floor 5 by providing brackets 37, which are placed with a laying section on the bearing covering or screed 6 and which have a holding section on which the bearing element 301 is placed.
the installation is carried out in such a way that initially, as in Figure 5A shown, the frame element 8 is placed on the unfinished floor 5, after which the supporting covering or screed 6 is applied to the unfinished floor 5 so that it is directly adjacent to the frame element 8.
the frame element 8 is shortened so that its upper side ends at most on the upper side of the adjacent supporting covering or below. The shortening can be done with a knife, for example.
a holding bracket 37 is placed with its laying section on the adjoining support covering. Its holding portion extends vertically offset downwards and offset horizontally to the interior of the frame member 8 .
the support element 301 is placed on this holding section. Since the laying section of the mounting bracket 37 has a vertical thickness of only 1 mm, a floor covering, for example tile covering, can be applied to the supporting covering over the laying section of the mounting bracket 37 without any problems using a tile adhesive layer with a conventional thickness, for example approx. 1.5 mm .
FIG 6 including the Figures 6A, 6B and 6C components of a further embodiment of a shower tray device 1 according to the invention are shown in different views in greatly simplified form in various schematic representations of principles.
the embodiment described has a support element 301, as is the case with the embodiments according to FIG figure 4 and figure 5 is explained.
the support element 301 has an edge area 311 and a central area 312 .
the upper side of the support element 301 is shown schematically in Figure 6B the underside of the support element 301 is shown schematically.
a fleece layer 39 is arranged on the upper side of the support element 301 within the edge area 311 , the fleece layer running over a part of the edge area 311 like a ring.
the fleece layer 39 can run over the entire edge area 311 in advantageous embodiments.
This fleece layer 39 is used to implement a particularly well-sealing adhesive bond using a sealing tape 10, as is shown in Figure 6C is shown to explain a room floor realized with the described embodiment.
the sealing tape 10 is applied to the fleece layer 39 provided on the upper side of the edge region 311 and glued both to this fleece layer 39 and to the upper side of the adjoining screed 6 as the intended supporting covering. This ensures a sealing connection between the screed 6 and the support element 301 .
the sealing strip 10 is closed horizontally and applied circumferentially to form a sealing sleeve, in this case a sealing ring, at the transition between the screed 6 and the support element 301 .
the support element 301 can be arranged adjacent to a wall at a transverse end and/or a longitudinal end, in which case the sealing strip 10 with its over the Edge region 311 protruding section is glued to the wall to ensure a sealing connection between the wall and the support element 301.
the sealing strip 10 that is implemented can be referred to as a sealing collar in the operating state, ie when the shower tray device 1 has been installed in a room floor.
a further fleece layer 38 is provided on the underside of the support element 301 within the horizontal extent of its edge region 311, namely within the same horizontal region in which the fleece layer 39 is provided on the upper side.
this further fleece layer 38 is not required to produce a sealing connection, this further fleece layer 38 is advantageous for the production of the support element 301 in that the support element 301 has a precisely definable shape. This is because the additional fleece layer 38 has the function of a counteracting layer, which ensures a counteracting pull relative to the tension generated by the fleece layer 39 provided on the upper side of the support element 301 . As a result, an undesired deformation of the support element 301 during the production process can be effectively counteracted.
