Description

The invention relates to a shower floor element according to the features of the preamble of claim 1.

Such a shower tray element corresponds to the internal state of the art of the applicant. In addition, on the DE 202005004179 U1 , the DE 202005018684 U1 and the DE 202005013327 U1 to refer to the more general state of the art.

With regard to the presumed construction of a shower floor element, the most favorable construction possible and, moreover, a sealing installation that is as safe as possible, of a shower floor element at a construction site is desired.

The invention is therefore concerned with the task of designing said shower floor element and further, that an advantageous installation option is given.

This object is achieved in the subject matter of claim 1, wherein it is based on the fact that the drainage channel consists of a trough lower part, which forms a peripheral edge of a slot opening of the drainage channel, and with a relative to the trough lower part mountable gutter upper part, the one forms further edge of the slot opening, wherein the gutter upper part for setting a desired slot width in the transverse direction relative to the trough lower part is different mountable.

Such a shower floor element can also be easily attached to the required size by cutting on site. The sealing arrangement in critical area of the drain and the drainage channel is nonetheless predetermined. In the other edge areas, the sealing can then be made on site by appropriate sealing strips in addition.

The arrangement of the drain can also be provided outside a corner region, in particular also in the center of an edge of the shower floor element. This design is particularly useful if the drainage channel is provided only on one edge side. The process can then be supplied by two opposite sides, but in principle only from one side.

The drain can be arranged on a lower plate part or a step surface which is lowered relative to the surface of the shower tray element. It can be provided connected thereto, provided in the drainage, elongated drainage channel. The drainage channel can also sit on the lowered step surface, possibly on an upper plate part, and the sealing element is arranged in any case associated with the drainage channel.

The connection between the drain and the lower plate part or a step surface can already be established at the factory. This is also preferably provided. The upper plate part can then be placed on site. It is as it were only plug or insert assembly required, usually also a bonding between the plate parts takes place. By virtue of the fact that the sealing element is advanced, preferably between the lower and the upper plate part, the drainage channel sitting on the upper plate part can be installed without the need for a seal in this area or for this on the construction site Measures would be taken. The seal is possibly provided as it were level in depth.

The shower tray element can be made in a uniform size, but adapted by cutting on site to the required length / width ratio or the required overall size. And this without significantly impairing the production already provided sealing measures are affected.

Due to the fact that the marginal edges of the slot openings are assigned to separate parts, a favorable solution with regard to the possible cutting of the shower floor element is also given. It only takes one of the parts, usually the gutter base, already factory-mounted. This can then be cut together with the foam part. The gutter top can be cut separately. In addition, both parts can be produced cheaply. For example, as plastic parts. In particular, for the gutter base offers a production in the deep drawing process. In addition, however, a production in the extrusion process or in the plastic injection molding process is possible. In particular, in a production in the extrusion process, it is favorable, in the sales set of the shower floor element already an end piece, as described below, provide, since it is also to be used when no cutting or separation of the sealing floor element and a gutter part must be made on site , For an extrusion part, as a gutter base, for example, is open on both sides. Due to the different mountability in the transverse direction of the gutter upper part for setting to set a desired slot width of the drainage channel, the width of the drainage channel can be adapted to the conditions on site. In a direct arrangement of the drainage channel on an ascending wall may be approximately with respect to the thickness of the Wandverfliesung or other surface position of the wall, which can protrude over the channel or in the groove, the slot width of the drainage channel can be adjusted by a suitable installation of the gutter upper part. In that case, the surface of the wall, that is, for example, a tile surface, then forms the counter-edge in the installed state.

The drain may include a drain cover and drain drain. These are also preferably plastic parts. In this case, it is preferable that the drain cover forms peripheral edge portions of a corner slit opening and that the drain cover is slidable relative to the drain lower portion having corresponding peripheral edge portions to change a width of the slit opening. Thus, in the corner region in which the drain is arranged, the desired slot width can be adjusted in alignment with the slot opening of the drainage channel. The drainage parts can be made by deep-drawing, but also as plastic injection molded parts.

It is also preferred that the marginal edges of the slot opening have a different height level, namely the outer peripheral edge, which is thus assigned in particular the trough lower part or the drain lower part, a lower height level than the other peripheral edge.

With regard to the drain lower part is further preferred that this has a drain opening and is provided in the direction of displacement, provided in the drain opening channel molding. The channel molding is preferably provided in addition to one or two terminal channel sections for connection to a drainage channel. The drain opening is arranged on the corner side and the gutter molding preferably directed away from the drain opening into the interior of the shower floor element. Further preferably, along a diagonal, wherein the diagonal also preferably forms the center line of the trough molding.

The construction of the drainage channel of the drain described above and in more detail below, but also with regard to a combination of gutter and drain, also have independent significance. In particular, without it being important whether the gutter is arranged or provided at the edge and / or on a shower tray element and / or on a step of a shower tray element, etc.

Furthermore, it is also preferred that the drain is designed as a drain-collecting housing. It is a substantially, optionally up to rust or slot-like inlet openings, closed housing, in which one or more drainage channels over (each) a side opening, said connection gutter sections, deliver. It is also preferred that this drainage collection housing, at least in relation to the initially treated claim, is assigned to a corner region of the shower floor element.

A drainage channel is preferably narrower than the collection housing.

It is further preferred that the upper plate part or the plate part or the step surface, on which one or more of the drainage channels sit, has a slope towards the drainage channel. It is also advantageous that at least two, possibly perpendicular to each other arranged drainage channels, the upper plate portion and the top of the shower tray element has two areas of different slope.

It is particularly advantageous to form the upper plate part with a peripheral step formation for receiving a drainage channel.

In further detail, the drainage channel can basically be formed as a metal part, for example as a sheet metal bent part, but also as already mentioned as a plastic part. If you can also shorten the length of a metal gutter, this is possibly even more advantageous for a plastic part.

With regard to a sealing element is first preferred that this is arranged between an upper and lower plate member. This usually leads to an approximately horizontal arrangement, wherein a part of the sealing element, which is usually provided as a sealing strip, approximately corresponding to one third or half of the width of the sealing strip, projects outwardly. But it can also be provided that a sealing element, in particular the factory pre-assembled sealing elements, on one edge side or on two intersecting edge sides of a plate member, preferably just the lower plate member, are arranged vertically, for example, glued from the outside, then up to a free stand given by bending over can be used to insert the sealing element in the surrounding soil.

As for the plate members, it is further preferable that one of the plate members, preferably the lower plate member, is composed of two or more individual plate members. This is particularly favorable in the case that different densities of these individual plate parts are selected. Preferably, then the upper single plate member associated with the upper plate member is selected to have a higher density. Because a higher-density foam, in particular particle foam, as described, already has on its own from a high waterproofness. In addition, in the lower single-plate part, which then has a lower density, more favorable form the necessary lower recesses for laying a drain pipe, etc. Also, an integral shower tray member may be formed with different densities or with a density (total) in the wall width described below.

A low density is given, for example, in the range of 20-40 kg / m ³ and a higher density in the range of 40-100, up to 110 kg / m ³ . In the stated numerical bandwidths, the values not given by way of example are also included, namely all intermediate values, in particular in 1 kg / m ³ steps. The said individual plate parts, in particular as far as the lower plate part is composed thereof, are preferably preassembled at the factory.

A sealing element can also preferably be arranged between two individual plate parts, in this case again preferably in the horizontal extent, as explained. Thus, such a sealing element is also provided offset from the sealing plane or setting plane of the process on the lower plate part - down.

With regard to the drainage channel, it is provided according to a further preferred embodiment that a support part assigned to the inlet slot is provided. This is particularly preferred if, as is preferred, the drainage channel has a transversely rectangular, partially closed profile, with a greater width than height. At least one side is then provided a relatively far freikragender upper leg, which can be supported low. In particular, in embodiments of the drainage channel as a plastic part, this proves to be advantageous.

A drainage channel preferably has assigned to the inlet slot a preferably molded, in the delivery state upwardly free-standing inlet edge. More preferably, in a drainage channel with partially closed profile two inlet edges, opposite, provided, between which then enters the water in the drainage channel. These inlet edges serve, for example, to form a stop for the sanitary surface to be applied, for example a tiling, or as a jointing aid.

More preferably, one or both inlet edges can be covered by an edge shoe. Hereby, a desired material or a desired appearance of the inlet slot can be made low.

A shower floor space may also be composed of a plurality of shower floor elements arranged next to one another, the shower floor area having two or more drains and three or more areas having different gradients.

A shower floor element with a drain and a gutter, which these elements are preferably arranged corner or edge side, can in a simple manner with another same shower floor element be combined. In particular, when the shower floor channels are associated with only one or two mutually perpendicular and tapered to the same corner edge regions of the shower floor element, can be achieved by the composition of two or more such shower floor elements nevertheless a nearly closed edge-side drain configuration. It can also be an actually closed edge-side drain configuration, be it with or without a continuous gutter inlet opening, be provided when the mutually facing gutter ends with corresponding connecting pieces, which thus form a channel section, transverse to the associated shower floor element edge sides, are connected.

In particular, a shower floor element of such a shower floor space may comprise one or more of the features as described above and below with respect to the shower floor element in detail.

a schematic plan view of a shower floor space with a centrally arranged with respect to an edge side of the shower floor element drain.

Shown and described, first with reference to the Fig. 1 and 2 , a shower floor element 1, which consists of two superposed foam plate parts 2, 3. The shower tray element 1 further has a drain 4, which in the usual way down in a drain pipe (not shown), optionally with an odor trap, continues. In addition, sealing elements in the form of sealing strips 7 are provided at two mutually perpendicular longitudinal edge edges 5, 6 of the lower foam plate member 3, which overlap in the corner, which is also associated with the drain 4. They are horizontal over the edges 5, 6 on.

Next, two elongated drainage channels 8 are provided, which are respectively associated with the peripheral edge 5 and 6 of the plate part 3. More specifically, however, they are seated on the upper plate member 2, there on a step surface of a stepped recess 9. The sealing member 7, on the other hand, is arranged between the upper plate member 2 and the lower plate member 3, i. between two foam panels. A drainage channel has a longitudinal extent that corresponds to at least twice its transverse extent.

The foam plate parts 2, 3 are more preferably made of a particle foam, for example. An EPS particle foam. This can be densities be realized from 25 -110 kg / m ³ . Preferred is a range of 25-90 kg / m ³ . However, non-exemplified values, namely all intermediate values, are also included in the stated numerical bandwidths.

Preferably, one or both plate parts 2, 3, more preferably but only the lower plate part 3, covered with a bonding agent layer. This also has sealing function. This adhesive layer can be configured in various ways. For example, it may consist of a polymer dispersion, e.g. an acrylate dispersion and optionally enriched with organic and / or mineral fillers. It can also consist of a plastic mortar combination. These are understood in particular to mean mixtures of hydraulically setting binders (for example Portland cement) and additives. These mixtures may have mineral additives and / or organic additives and / or polymer dispersions as a proportion. In addition, the coating may also consist of another mortar coating. It is essential that a desired water resistance is achieved. Embedded in this coating or arranged thereon, the sealing tapes 7 are then preferably provided.

The specified coating can only be provided on the upper side and preferably on the marginal edges or frontal edge surfaces of the plate part 3. But it can also be provided completely enveloping the plate member 3.

As further seen, the drain 4 is designed as a drainage collecting housing, with in detail two lateral inlet openings 10, 11, cf. also Fig. 4 and 6 , In the middle, a downwardly discharging pipe part 12 is provided.

The process 4 has a square plan in the embodiment. The upstanding housing walls 13,14,15,16 have a height, which the height h of the upper plate part 2 in the region associated with the drain 4 corresponds (outside the step recess 9). As the upper conclusion, a lid member 17 is provided, which is inserted from the top into the preferably one-piece from said walls 13 -16 and the bottom 18 existing lower drain part. It in turn has a peripheral edge 19 to accommodate a tiling. On the underside, it has molded support feet 39. It may be provided for inspection purposes as operationally removable.

In addition, in the exemplary embodiment, slit openings 21 (see, for example, FIG. 2) are also provided, as an extension of the inlet slots 20 of the drainage channels explained below Fig. 4 ) provided on the drain 4. The slot openings 21 extend at the edge. The slot openings 21 result between the housing walls 13, 14 and the associated marginal edges 19 of the cover part 17. The support legs 39 or on the cover part 17 and / or the support legs 39 integrally formed spacer portions 40 provide for the fitting of the cover member 17 in the drain housing at safer Clearance of the slot opening 21st

In the exemplary embodiment, the two walls 13,14 aligned vertically with the corresponding Eckausformung the marginal edges 5, 6 of the plate member 3. The upper plate member 2, they supplement as it were through to the corner. Because the upper plate member 2 has a corresponding to the drain 4 negative, here inside corner-shaped recess 22. At the same time results in a favorable mounting orientation of the upper plate member 2 on the drain. 4

The sequence 4 and the said sealing bands 7 are preferably already factory-mounted, ie preferably glued in each case, so that on-site only the two other sealing strips attached and the upper plate member 2 needs to be placed.

The gutters 8 may be plug-mounted, as well as from the illustration according to Fig. 4 results. To achieve the required tightness can be worked in the mating areas with a suitable adhesive.

Since, as mentioned, it is possible spatially to adapt this shower tray element, namely as by separating along a line L1 or L2, ie preferably parallel to one of the marginal edges 5 and 6, but in any case leaving the occupied by the drain corner portion of the shower tray element, belong to the kit of such a shower floor element also Endverschlussteile 23, as in Fig. 5 are shown for a gutter. At the factory, the gutters 8 are preferably provided with a length corresponding to the marginal edges 5, 6 minus the proportional dimension of the outlet 4.

As can be seen from the presentation according to Fig. 5 or Fig. 6 There is a gutter or drainage channel of a rectangular cross-section with a marginal, here outside edge, upwardly opening slot opening 24. This slot opening 24 is given by a correspondingly upward over a drainage ceiling 25 projecting wall whose freestanding height range to the later applied sanitary surface , in the form of a tiling, is adapted. The substantially rectangular profile has an engagement leg 26 which engages over the upper plate member 2 beyond the step formation. For this purpose, the plate part also has an adapted further gradation 9 '.

Moreover, the upper plate part 2 has two distinct regions a and b, which are each formed with a gradient. And a slope that is aligned to the process 4 out. In the area of the corner recess 22, these areas have the same, lowest level. The gradient is low in this regard. Approximately in the range of 0.5 ° to 3 °, whereby here also all intermediate values, especially in 1/10 ° steps, are included in the disclosure. The regions a, b abut each other along an edge 33, which thus results in a ridge line. In practice, or with regard to the sanitary surface still applied thereto, it can also be, for example, a rounded transition.

Likewise, the step formation 9, i. the step surface, on which a gutter is seated, provided with a slope to the drain 4 out. Even very small slopes, starting at about 0.5 °, can be used here. Preference is given to a gradient in the range of 0.5 ° to 3 °, whereby here too all intermediate values, in particular in 1/10 ° increments, are included in the disclosure.

Fig. 7 shows a composite and teilverfliestes shower floor element. 1

In reference to Fig. 8 a variant with respect to the lower plate part 3 is shown. Basically, the extent described here as particularly described structure but also for the upper plate part 2 in question.

It is essential that the lower plate member 3 in this embodiment consists of two individual plate parts 34, 35. These individual plate parts 34, 35 are preferably already factory assembled, in particular adhesively bonded, more preferably then also here with already attached or glued process 4. It is also important that the upper single plate part 35 from an at least practically or substantially preferably completely watertight material exists. In particular, a high-density particle foam, having a density as already stated above. By contrast, the lower individual plate part 34 is preferably made of a foam of lower density, as stated earlier in this regard. It is particularly suitable here, the sealing tape 7 between them to arrange and glue both individual plate parts. Thus, the sealing plane is also below the level of the drain 4, whose seating surface on the lower plate part 3, given. It may also be sufficient to provide only the upper single plate part 35 with a primer layer, as explained in detail above.

In the presentation of Fig. 9 is a corresponding plate member 3, which in principle can also be constructed as regards. Fig. 8 described, but can also be provided as a materially uniform plate member 3, shown with an alternative arrangement of the sealing bands 7. These are here at the edge edges 5, 6 associated end faces mounted vertically extending, with a significant proportion of its width, about a third to half, freely protruding upwards. Thus, the sealing member 7, as in Fig. 9 also indicated, are bent to the outside, and then to provide the density connection to the surrounding soil in the installation.

In reference to Fig. 10 is a further cross section of a gutter 8 is shown. Basically, the cross section is not changed compared to the embodiments already described.

It is essential, however, that a support member 36 is provided inside the gutter 8. This serves, in particular when the drainage channel 8, as provided according to a preferred embodiment, as a plastic part, such as plastic extrusion, is designed to support the upper free-standing part, the drainage ceiling 25. It may be at the support member 36 is also a plastic part or even a metal part. This support member 36 is not formed throughout the length of the gutter, but only locally, as seen with a width of, for example, 1 or 2 cm in the longitudinal direction, provided. It can be provided - with a distance from each other - a plurality of such support members 36.

Next, the gutter 8, as already mentioned in principle, to form the inlet slot 20 upwardly free-standing, parallel and oppositely arranged inlet edges 37. These inlet edges can, as also in Fig. 10 is shown, be covered individually or in each case by an edge shoe 38. This may be, for example, a stainless steel part or another material adapted to the desired sanitary surface from which the shoe is made.

The gutter 8, as in Fig. 10 For example, in terms of its rectangular cross-section, it may have a maximum dimension of 50-60 mm and a narrow dimension of 25-35 mm. The inlet edges or marginal edges in the region of the drain preferably each have a freestanding height of 5 to 15 mm, more preferably 10 mm. The drain itself or its free-standing housing walls preferably have a height in the range of 30-50 mm, more preferably in the range of 40 mm.

Related to the Fig. 11 and 12 are schematic representations of a shower floor space, composed of several of the above or below further described shower floor elements reproduced.

In the embodiment of Fig. 11 two shower floor elements are arranged side by side in one of the described embodiments, here also assigned a given by walls 28, 29 and 30 room corner. In detail, the shower tray elements are arranged such that the drains 4 are each assigned to a corner region formed by two converging wall regions 28, 29 and 29, 30. Independently of these wall areas, the shower floor elements are thus arranged so that the drains 4 are each arranged on the outside of the shower floor space in a corner area. This is followed by two drainage channels, which are at right angles to each other run and formed in the manner described at the edge of a single shower floor element.

In summary, this results in a U-shaped course of the gutter, which only has an interruption in the region of a bearing plane 30 'between the two shower floor elements. Due to the respective given, opposite slope to the opposite processes 4, but nevertheless results in a favorable and advantageous overall drainage.

In the aforementioned embodiment of the Fig. 11 are still more simple elements 31, 32 upstream of the described shower floor elements provided. In principle, they can be configured in the same way as explained above from plate parts arranged one above the other, but also as one-piece shower tray elements. They do not have their own processes, but can be arranged overall with a slope to the respective upstream shower floor element of the type described. But you can also basically have a planar surface.

In the embodiment of the Fig. 12 are four shower floor elements, as basically arranged in one of the embodiments described here. In such a way that the processes 4 each adjacent to each other. As can be seen, this results in a cross-shaped course, in double lines, formed by the drainage channels, the overall processes.

Related to the Fig. 13 to 23 is a further embodiment of the shower floor element explained.

This is preferably a base part in the form of a one-piece foam part. This foam part can also be made of several Plate parts are composed, but further preferably factory pre-assembled or pre-bonded together.

The shower tray element 1 also has in this embodiment on its surface, which is then later tiled example, preferably areas of different slopes a, b, which are separated along a diagonal.

Further, the shower floor element 1 is stepped on two edge sides, with step surfaces 9, on each of which a drainage channel 8 rests in the installed state. These are intersecting edge sides of the shower tray element 1, wherein a drain opening 55 is provided in the corner area in which the edge sides intersect.

The drainage channels 8 and a drainage base 56 are preferably integrally formed with each other as shown. They can also be composed of several parts. The sealing tapes 68, see Fig. 14 . 15 , Are attached to the provided with a gutter 8 edges vertically mounted, as basically already concerning Fig. 9 explained.

The gutters 8 show how about out Fig. 15 results in a generally U-shaped cross section, which is open at the top.

In reference to Fig. 23 The following further features, individually or in combination, may be provided on the gutter 8, preferably the gutter base. On the outside, the gutter may have a step portion 57, which is offset from the peripheral edge 47 down. This can serve as a stop edge when attaching tiles or other wall cover the associated rising wall, where the shower floor element is possibly arranged.

The bottom region may be in the form of a curved bottom, with a deep-wall formation 58, which is preferably provided asymmetrically with respect to the center. This, in order to ensure an advantageous flow rate even at low water flow. Here, the step surface on which rests the gutter, be designed according to example. Further, on the inside of the shower floor element associated peripheral edge of the free drain profile a console-like inwardly projecting projection 59 may be formed. This in order to avoid an excessive free cantilever extent of the channel top, if necessary. It thus results from the assigned on the bottom trough surface portion 60 from an undercut. To the interior of the shower floor element 1 through a flange 41 connects to the drain lower part, which rests in a preferably provided further, upper step recess 42 of the shower tray element 1. But it can also simply rest on the surface of the shower tray element 1 and be integrated by a coating, so that there is no disturbing height difference in the transition to the shower floor element.

The gutter 8 is made up of a gutter bottom 43 and a gutter top 44. The channel bottom 43 has the aforementioned U-shaped cross-section with the flange 41st

Here, the flange 41 opposite U-leg 45, see Fig. 15 , at the same time a marginal edge of the slot opening.

Like next Fig. 15 can be seen, the opposite edge 46, which is formed on the trough upper part 44, higher than the peripheral edge 47 on the U-leg 45. Alternatively, it can also be provided that the U-leg 45 is designed to be longer, so that the marginal edges 47 and 46 are at the same horizontal level. In principle, the marginal edge 47 in the installed state can also be designed to be of a higher-than-projecting design Border edge 46. The gutter upper part 44 is basically formed in the form of an L-profile. The L-bend forms the peripheral edge 46. The L-web, which may have openings for better tile attachment, has a length 1 extending from the peripheral edge 46 to the interior of the shower tray element which preferably corresponds to two thirds or more of the width b of the gutter , More preferably, the one to three times, or even more, the width b, in which area information also all intermediate values, in particular in 1/10 steps, in terms of one to three times, but also beyond, is included. The L-web and the flange 41 are flat in the installed state. In that regard, a free displaceability of the trough upper part in the transverse direction is possible to then in a desired with respect to the desired inlet width position the fixed assembly, such as by the already applied tile adhesive in the event of tiling, make. On the flange 41 can also be omitted. A support for the L-bar can be given in the installed state solely by the receiving shower floor element.

The gutter upper part 44 may also, in its projecting over the trough area, which is not shown in detail, have a radially downwardly facing support leg, alternatively or in addition to the mentioned console training of the gutter base.

With regard to the outlet 56, a separate drainage top 48 is provided which, on the one hand, is seated in the channel by means of feet 49 in the assembled state and, on the other hand, rests with a flange section 50 on the associated step surface 51.

In the shower floor element 1 is further associated with the drain opening 55 a diagonally corresponding groove formation 52 is provided in the embodiment. The feet 49 of the drainage top 48 are designed to be in any case, in some cases - with a horizontal displacement of the discharge part 48 - can retract into the channel molding 52. As a result, the drainage top 48 can be moved horizontally, specifically here: diagonally, to achieve different slot widths of the gutter opening. In the same way, the gutter upper parts 44 can be moved transversely to the gutter extension and then covered with a tiling, whereby they are also fixed at the same time. The fixation takes place in the course of installation of the channel shell. For this purpose 44 through-openings 53 are formed in the gutter upper parts.

The presentation of the Fig. 14 shows an assembled form of the shower tray element 1 with a first slot opening width s of the channel opening.

In the sectional views of the FIGS. 15 and 16 this width is reproduced. In the sectional view of Fig. 17 a larger width s' is reproduced.

From the Fig. 18 the drainage top 48 with the molded feet 49 can be seen in greater detail, here in exploded view. In the Ablaufoberteil can still be inserted a drain grate 54. It can also be a tile part. In the latter case, it may also be appropriate to provide a separate support part for the tile part. Maybe for bonding with the tile.

The Fig. 19 shows a sectional view through the article according to Fig. 14 , cut along the line XIX-XIX. It can be seen that two feet 49 of the outlet upper part engage in the groove formation formed here also by the gutter lower part, which permits the diagonal displacement of the drainage top part.

In reference to Fig. 20 It is shown that a tile 61 can also be inserted into the drainage top 49. Here, a support member 62 is suitably provided with which the tile can be glued about with conventional tile adhesive. Likewise, it can be a natural stone part, with no special support being required here as a rule.

In reference to Fig. 21 is a possible formation of a tail 63 shown for a gutter. This is necessary when a cutting of the shower floor element has been carried out by transection of the gutter. But also, as mentioned above, for example, in the production of the gutter part or the gutter base in the extrusion process. In this case, the end piece 63 initially has a cuboid body part, which is adapted to the cross section of the channel molding. In the case of a design according to Fig. 23 an amended contour would be given.

Further, the end piece 63 has a preferably hinge-hinged cover member 64, with respect to Fig. 22 is explained in more detail.

Fig. 22 shows a possible installation situation of a shower floor element described here, wherein a separation has taken place perpendicular to the course of the gutter

In the open due to the separation gutter is the end piece 63 according to Fig. 21 used, such that the opening faces outward. At the same time the installation situation with respect to an upstanding wall 65 is shown, which is provided with tiles 66. The tiles 66 protrude approximately into the gutter and thus form the associated edge. The tail 63 is also provided for the advantageous transition between here in the embodiment, two differently arranged sealing bands. The indicated sealing band 67 is arranged horizontally, while the indicated sealing band 68, see also Fig. 5 , glued to the outside edge of the edge is always vertical.

The sealing strip 66 is now provided resting on the end piece 63 and is then sealed by folding the lid member 64 and glued. A protruding edge portion 67 'of the sealing strip 67 is folded up after crossing the end piece 63 and can be glued so flat with the existing vertical sealing band 68th

In reference to Fig. 24 is a further cross section through a gutter base 43 is shown. Here, a V-shaped cross-sectional configuration of the bottom of the gutter base is provided. Seen in the longitudinal direction, this V-shaped design ends before the drain 4. This is also preferable if, for example, a so far one-piece design is provided.

Related to the Fig. 25 and 26 an alternatively designed end piece 63 is provided. This tail is made like a plug. On the front side a marking is provided, on the upper side by a profiling 69 and on the front side by a symbol, here a capital letter "I" 70. This is to make clear that this side is to be arranged towards the inside. End side, opposite to the end face 71, the total preferably designed as a plastic injection molded part end piece 63 is hollow, more preferably, chambered. This by a here only indicated central partition wall 72nd

As can be seen in particular from the cross-sectional view according to Fig. 26 can recognize, the bottom 73 of the end piece 63 is profiled in cross-section, this in adaptation to a profiling of the gutter base 43. In the embodiment, the adaptation corresponds to the in Fig. 24 Trough lower part shown in cross section.

On a cover member 64, as in relation to the end piece 63 according to Fig. 22 explained, is omitted here. Rather, this tail is designed purely cuboid.

In the installed state, the top 74 of the end piece 63 is accordingly according to Fig. 25 directly covered by the sealing tape 68, as with respect Fig. 22 explained. It can be laid in the same way.

In reference to Fig. 27 is a shower floor element arrangement with only provided on one edge side drain 4 shown in a schematic view from above. The drain 4 is arranged centrally. Accordingly, it is preferably provided that the sanitary surface of the shower tray element is designed sloping only in one direction, namely in the direction indicated by the arrows P direction. In addition, within the gutters, of which only the inlet slots 20 can be seen in this view, each formed a slope to the drain 4 out. The bottom of the gutter drops according to the sequence 4 out. In contrast, the marginal edge 47 or a tiling covering it or a covering curtain stone or the like can be provided running horizontally on the wall side or terminate horizontally on the underside.
