Description

The The invention relates to a foam shower tray element, preferably plate-like foam shower tray element, with a drain, the drain having a pot bottom drain pot and one by a high flow diversion has formed odor trap and from the drain pot a Drain line extends to an edge of the shower tray element.

Foam shower floor elements in the aforementioned plate-like design, for the formation of floor-level showers have already become known in various embodiments. It is for example on the DE 20311 666 U1 directed. The state of the art is also on the WO 2007/023149 A1 directed. In addition, especially with regard to sanitary surfaces or concrete shower trays, which have a downwardly facing Randabwinklung on the not previously published European patent applications with the application number 08168986 , Filing date 13.11.2008 and 08168984 , with the same filing date. The content of said European patent applications is hereby incorporated in full in the disclosure of the present application, also for the purpose of incorporating features of said earlier European European patent applications in claims of the present application.

It there is a need for such foam shower floor elements in terms of installation as easy as possible assembly to design. Also, a possible universal installation, even under difficult installation conditions, d. H. especially at relatively low available vertical height, to be possible. The invention deals with the task, a montetechnisch advantageous designed foam shower floor element, especially for a floor level and floor level Installation, specify.

A possible solution to this problem is the subject matter of Claim 1, with the object being that the Odor trap at least partially outside the drain pot is formed and the height-wise flow deflection outside the drain pot is formed by means of the drain line, including those at a level of the bottom of the pot or higher Drain line within a vertical extension (thickness) of the shower floor element over their length led at different heights is. This makes it possible to include the entire process including Drain pot and odor trap within the thickness of the plate-like Shower floor element accommodate. It can over a lower bearing surface of the shower floor element projecting Elements that have a special excavation when installed would require avoided. In addition, the process, at least partially, immediately pre-assembled and in particular pre-sealed be factory fitted in the shower floor element. The seal is preferably achieved by an adhesive layer (see also below), if appropriate, in particular in a transitional area to the drain or the drain line also by usual Sealing tapes or a continuous sealing foil.

It is not necessary that an actual drain pot is formed in the sense of a cylindrical part. It may be so far also a deflection, usually from the vertical into the horizontal, act, which is followed by the drain. In any case, the drain pot is that part of the process addressed during drainage by the expiration of the Shower floor element initially runs full until overflowing in such, arranged in the flow direction behind areas the drain line occurs. This can also be provided, regardless further water inclusions by vertical deflection of the Drain line, that in the area of the drain pot itself already a complete water seal (odor trap) given is. By the heights different Guide the drain pipe and possibly also in a drain pot itself already provided flow deflection baffle, remains in the pot or the said deflection a certain water level are preferred, so that already a part of the odor trap can form. The odor trap is known to be replaced by a ascending section, or between two rising sections, formed the line. With regard to the flat design of the Odor trap, which with regard to the accommodation in the Thickness of the plate-like shower floor element is displayed, can It is also recommended, such an odor trap two times to provide one behind the other in the longitudinal extension of the drain line.

Further Features of the invention are below, also in the figure description, often in their preferred allocation to that already above described claim concept described. You can but also in an assignment to only one or more individual Features of this claim concept or independent or in another overall concept of importance.

In particular, it is preferred that it drain line is wave-shaped. This means that the discharge line runs in a longitudinal cross section, a cross section in the flow direction, alternately up and down. In this case, "total" means that the change in height is of such a magnitude that, after the changeover, a conduit bottom is in a horizontal position level or above a duct ceiling before the change extends. This with a rise angle and a descent angle. Preferably, the rise and / or fall angle in the range of 35 to 55 °, in particular 40 to 50 °. Here, the angle data, based on the course of the subfloor, in the cross section of the drain line. The upper floor or ceiling area of the drain line can have lower rise and fall angles, this also because it can come in the range of height changes to a cross-sectional reduction of the line. Based on ei ne central axis of the rise and / or descent angle is therefore preferably in the range of 20 to 40 °. With regard to the stated degree range specifications, all intermediate values, in particular in 1 ° increments, are also included in the disclosure. In any case, it can be seen that the angles of rise and descent are preferably acute angles.

In further detail is provided that in the longitudinal direction the drain line two by hump-like in the longitudinal cross-section Course of the bottom floor formed bottom flow buttocks are formed between which flow obstacles a duct ceiling in the sense of a gegengegenliegenden Deckenbuckels so far pulled down that they are below the humpbacks the soil flow obstacles stick out and so an odor trap allows. This is in it alone through the drainage line, outside of the drain pot formed odor trap.

These ground flow obstacles given by the hump-like course of the conduit floor, cooperating with the duct ceiling, correspond to the previously described up and down changing course of the drain line.

The initially formed in the flow direction ground flow obstacle represents here with its rising edge at the same time the conclusion of the Drain pot dar. The descending edge is part of the drain line trained odor trap. The subsequent second Ground flow obstruction completed with its rising flank the descending flank of the first ground flow obstruction and continues to work in conjunction with the opposite Deckenbuckel the odor trap inside the drain line. The descending flank of the second ground flow obstacle at the same time forms the transition to the subsequent usual preferably formed with a circular cross-section, drain line.

In Particularity is further provided that an overlap between the ground flow obstacles and the counter hump a free vertical opening dimension or more the drainage line between the humps corresponds. Especially can cover up to twice the said correspond to free vertical opening dimension.

One Distance between the ground flow obstacles, in the flow direction seen, can be 2 to 10 times that of said free vertical Measure correspond.

Especially is also preferred that the process in any case until the uppermost area of the second floor flow obstruction is formed with a width which exceeds the thickness of the shower floor element. In particular, a width that is more than the thickness of the shower floor element, in particular 1.1 to 3 times the shower floor element, wherein here also all intermediate values, especially in 1/10-steps in the Disclosure are included.

in the Individual is also important, that preferably no check valve is provided. Hereby, on the one hand, the desired high flow also be ensured again supportive. On the other hand, enough compensation space is created to a possible repression of the water column compensate. A high flow rate is also given by that the bends are formed with such a shallow angle are that in the upper areas in common use remaining air after some flushing, when using a corresponding shower, become air-free and so a self-priming Water column results, which additionally supports zend the output of the drain increases. It is preferably not a part in the entire drainage system of the shower floor element, which consists of Drain pot and the drain line exists, existing, due to functional Agility could turn out. Further preferred are as Separate parts only one insert in the drain pot and / or a drain grate covering the drain grate available. Both parts can be readily seen up through the drain hole be removed in the shower tray element for maintenance and cleaning.

Instead of a round or square process described here can also provided on the drain pot directly seated channel drain be. Here, the drain pot over its full height adapted to the gutter extension (ie instead of round, elongated be trained). But it can only be in an upper area be provided the elongated design of the drain pot. Next can also in the usual round drain pot, which possibly formed with a slightly smaller vertical extent, a gutter be placed so that the channel bottom immediately opens into the drain pot.

in the Interest in a space-saving arrangement, but at the same time in the interest a stability, it can also be provided that said ground flow obstacles in their respective lower area in the floor area fit the shower floor element, so possibly a part of Form bottom surface of the shower floor element at the same time.

There the soil flow obstacles in cross section at the same time They can also form bridge-like elements advantageously underlined by appropriate Durchgriffsverbindungen the shower floor element be. These penetration connections can be integral with the shower floor element, otherwise preferred from the said Foam, to be formed at the same time. Between two punch-through connections, viewed in the direction of flow, then results in a window-like opening, in which down the drain line odor trap forming Floor area of the drain or the drain line can be exposed.

The addressed bridge-like training in the field of flow obstacles is at the same time also advantageous in terms of stability. It provides a vault structure that is cheap to the overall stability of the process and also soil element can contribute with clamped process. This is in particular also important that the extension of such a vault, So from bottom to bottom, about 1 to 3 times, preferably 2 times, here also all intermediate values, in particular in 1/10 steps, which includes disclosure, the thickness corresponds to the shower floor element.

The procedure described here can also be advantageously integrated into a shower floor element with a marginal grading, as for example from the non-prepublished European patent application with the filing date 26.01.2009, Anmeldeaktenzeichen 09151299.6 , is known. The content of this European patent application is hereby incorporated by reference in its entirety, also for the purpose of incorporating features of said European patent application in claims of the present application. It is preferred that the drain pot, possibly by means of an inlet part inserted or screwed therein, opens at the level of the lower stage and preferably also extends only in the height range of the lower stage. This is particularly advantageous if such a shower tray element is formed from two plate bodies arranged one above the other to form the step. The drain can be installed in the lower plate part, for instance by simply inserting it from above, and the upper plate part can then be provided so that it does not have to take any function with regard to the drain.

With regard to an integration of such a process in a two-part design shower floor element, as in the aforementioned European Patent Applications 08168986 and 08168984 discloses, in particular, the advantage that such a shower floor element can be formed with very low vertical height.

Further it is preferred that the shower tray element is a bottom surface and that the bottom of the drain pot in the bottom surface runs. At most he can with a distance to the top to the underside surface, which is 10 mm or less. The integration of the drain pot into the Bottom surface of shower floor element is an integration of the drain pot in the bottom, the support surface, the plate-like shower floor element. In this respect, an alignment is aligned a bottom portion of the drain pot, preferably if this flat surface, with the underside surface prefers. It can also be about several, with their tips located in a common (flat) surface, Ground projections act.

Regarding the measure, the drain line at a height to provide the pot bottom or higher, is in Regard to the running at different heights Drain line preferred that at least one lower wall region of Drain pipe above a height level of the pot bottom - in sections - runs.

Also it is preferably provided that the drain line at least partially finally with the underside surface of the shower floor element or at a distance of 10 mm or less from the underside surface runs. This section can also be provided be, which in a lower area of the drain line with clearly greater distance to the underside surface run. By a final with the bottom surface Guide the drain line is also the drain pipe in the Bottom surface, so the bearing surface of the plate-like Shower floor element, integrated.

Farther it is preferred that the drain line is a vertical extension Having the shower floor element exceeding width. This is at a small thickness of the plate-like shower floor element, in particular, a thickness of 100 mm or less, a favorable Drainage achievable. In addition, this can also be done in the areas where the drain pipe in the upper or lower surface of the plate-like shower floor element included runs, a cheap area support to reach.

The drain line can also at least over a partial length of the thickness of the shower floor element correspond. At least over this partial length, the shower floor element is formed in this area in the thickness direction alone by the drain line.

In the previously mentioned embodiments, in which the drain line runs almost or flush with an upper side or a lower side surface of the shower floor element, the drain line is also integrated into the support structure of the shower floor element. There are such surface elements of the drain line exposed or at least provided without an integral with the shower floor element otherwise connected foam cover that - based on the top of the plate-like shower tray element - for small tiles, for example, have a footprint of 1 cm ² or more, for example, towards 25 cm ² , a tile is only within a vertical projection of the - located without such an integral foam cover in the shower floor element - drain line.

Especially it is preferred that the foamed structure of the shower floor element outside of the drain pot or a drain grate one the drain line receiving through hole (in vertical direction) leaves. This passage opening may be in terms of their length over a third or more, based approximately on a rectangular floor plan, one long side extend the shower floor element. Here, the drain pot is preferred or the drain above about the middle of the plate-like shower floor element arranged. This, because of the described training of the drain line with respect to Formation of the odor trap a certain length extension the drain line used alone to form the odor trap is. This length extension used to form the odor trap is about two to ten times greater than one Diameter measure of the drain line amount. Hereby are also any intermediate values, especially in 1/10 diameter steps, included in the revelation. The reference to a greatest Diameter measure is particularly important if, as preferably provided, the drain line at least partially and preferably in the area in which they - with - the Odor trap forms, with a flattened, of the circular shape deviating profile, in particular a rectangular profile formed is.

The called passage opening, summarized with the Drain pot and possibly a drain grate above it Ausnehmenden opening, is preferably keyhole-like designed. With a relatively large, preferably at one Circular shape oriented opening area in the area of the drain pot and a subsequent, to a side edge oriented towards smaller opening width.

A Another embodiment may also provide that the passage opening is formed rectangular, more preferably with a Vejüngung to Edge out. The taper may be provided such that initially over a partial area the walls the opening wedge-shaped converge and then back to the edge with a smaller distance measure extend parallel to each other. A typical biggest one Width of the passage opening is in the range of 80 to 150 mm, more preferably 100 to 130 mm and in the narrow range at 50 to 90 mm, preferably at 70 mm.

Further is preferred that the drain line in the region of the passage opening Carrier of an adhesive layer for tiling is. This adhesive layer can be applied directly to the drain line. It can also be on a drain line covering Cover be applied. In this respect, in particular, a solid plate part preferred as a cover. It is also possible that Covering bridge-like, under edge-side support on the foam shower floor element, in the region of said opening the drain line is covered. On the one hand, the drainage pipe so high or with the best possible use of the given Thickness. On the other hand, it is also preferable to the edge seen, after completion of the odor trap a certain slope the drain line to thereby also the process then to promote further in the floor plan area of the shower floor element. The gradient can, for example, in the range of a few millimeters, about 5 to 10 mm per meter, be given. Due to the altitude different leadership of the drainage pipe to form the Odor trap this also has a certain elastic mobility, especially in the turning areas. If, for example, as preferred, one after the deflections for the odor trap rectilinear Section of the drain line given a slope of For example, 0.2 to 0.4%, so a slight slope, This difference can be due to the mentioned flexibility even by elastic deformation readily on 1, 2, 3 up to, for example, 4% can be increased.

Alternatively or additionally, in the event that the plate part is not provided to the edge or over the entire longitudinal extension of the drain line, a filling of remaining gaps with a mortar-like material, for example. The material of the adhesive layer can be provided. In addition, however, even under the plate part remaining gaps can be filled with said mortar-like material. In this context, it is also preferred that the drain line still with a foam sheath, eg. Soft Foam wrapping, about how you know them in principle of the sheath of heating pipes to provide. Further preferably such that stomata remain up to a bottom of the shower floor element or, in the passage opening of the shaft, to a floor on which the shower floor element is set up during assembly. Hereby, on the one hand, the remaining clearances can be kept small in a simple manner. On the other hand results from the backfilling with said mortar and due to the reaching to the bottom gap spaces as it were a mortar vault, which is favorable for a load transfer. A relatively thin layer of mortar is also advantageous in terms of low shrinkage of the mortar during curing. Furthermore, such a foam sheath also offers the associated advantages of sound decoupling and thermal insulation and prevention of condensation.

Regarding the thickness of the shower tray element is further preferred that this is 70 mm or less. On the other hand, it is preferred that the thickness of the shower floor element is 30 mm or more. It should be further considered that the thickness in the Edge area is the largest, as a rule Slope to the process down the top of the shower floor element is trained. The gradient can be at a shower floor element with a border dimension of, for example, 1.2 by 1.2 m up to a center 15 mm. Therefore, the thickness of the shower tray element, based on edge 70 mm, in the area of the immediate connection of the shower floor element to the drain pot with eg 55 mm.

The here given ratios in relation to the thickness of the Shower floor element are, if not in individual cases something else is stated, always on the largest thickness in the outer edge region based.

A typical floor plan of the manufactured shower floor element (factory) is in the range of 1100 times 1100 to 1300 times 1300 mm, preferably at 1200 by 1200 mm. Such a shower floor element may be due to the preferred design, as below explained, then on site to adapt to given dimensions be separated. For example. can the adjustment in one direction or in two mutually perpendicular directions up to a Third, this is also preferable because of Distance to an outer edge provided pre-sealed End of the drain line.

The mentioned embodiment of a plate-like shower floor element is particularly advantageous in terms of training a shower room composed of several plate-like shower floor elements. In this case, however, preferably only one, more preferably a central, shower floor element the said sequence with subsequent discharge line, with partial formation of the odor trap through the drain line, on. In this respect, the shower floor element consists of a drain and the drain line with the odor trap base element. Next from one or more attachments., Which prefers the factory pre-sealed drain line, including the drain pot, which also preferably integrally formed with the drain line may be in terms of a connection end for a Installation on-site sequence forwarding with complete a peripheral edge of the base element. The said But connecting end can also protrude like a plug from the base element. In addition, it can be set back regarding be provided the edge. In the case of the deferred Arrangement is particularly preferred that the connection end to below a cover plate is set back. The cover plate ends in this case at a distance from the peripheral edge of the base member. Also in this case, the connection end flush with the Edge of the cover plate ends or further set back be given under the cover plate. The drain line can then by connecting a sequence forwarding, which is preferred by simple horizontal connector, if necessary by means of a comprehensive Muff, is possible in the base member or an attachment be continued. This can also be a cut or filling in predetermined or freely chosen openings, For example, also given outbreak openings made become. The assembling of the base element with one or more Attachments may be provided butting abutting be. Here can be done by known sealing tapes or films the sealing end can be reached on the upper side. But it can too a tooth - like meshing of edge portions of the Base element and the one or more attachments may be provided, the are prestructured accordingly edge. Also in one Such a case may additionally be a seal of the resulting Joining area by a covering sealing tape or a covering area Sealing foil, possibly with edge overhang for connection to the be provided surrounding soil or masonry.

The attachments may be formed in particular like a bolt, so with a rectangular plan and preferably also rectangular cross-section. In this case, they are furthermore preferably provided in a set, that is to say summarized or as additional parts for a shower floor element described here, such that at least one of the locking elements exceeds the marginal edge length of the shower floor element. So can be cheap dull aneinan the abutting corners are formed with the attachments. In addition, the shower floor element, as described here, can be low-cost adapt, in particular by separations parallel to the drain line, accordingly offset laterally thereto, or in a region opposite to the extension of the drain line.

The Drain line points, in particular with regard to the already mentioned non-circular cross-section, at least over part of its extension one Horizontal dimension greater than the free Vertical dimension.

The Embodiments described herein are particularly gravity operated Expiration provided (passive expiration). You can also join Sequence support, for example by an electric pump, be provided (active sequence).

Shown and described, first with reference to the 1 and 2 , a plate-like shower tray element 1 that is essentially made of a foam body 2 consists. With regard to the foam, it may in particular be a particle foam. For example, an EPS particle foam. It may also be an extruded foam, XPS foam. Furthermore, it can also be an integrally foamed foam, for example a polyurethane foam. The foam can be given here with a higher density to the outside; but it can also be a total homogeneously foamed foam.

The plate-like shower floor element 1 has a thickness d of 70 mm in the embodiment. As can be seen, this is focused on the thickness in the edge region. Due to a gradient usually formed towards the slope, the thickness is immediately lower at the outlet. Compared to the edge, the thickness at the outlet, for example, by 5 to 20 mm lower, and this is particularly dependent on the overall size of the shower floor element.

At least on the top, possibly also on the front edges, possibly also on the underside, that is Foam element provided with a primer layer. For example, it may be a polymer dispersion, especially a non-reactive polymer dispersion. Also, for example, an acrylate dispersion. It can contain organic and / or mineral filler. The primer layer may also consist of a plastic-mortar combination. These are understood as meaning, in particular, mixtures of hydraulically setting binders (for example Portland cement). These 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.

This primer layer allows to apply a sanitary surface in the form of tiles in a favorable manner. This is, for example, to understand a natural stone, possibly in the form of an integral plate, so for example. Natural stone slab. On the other hand, because it is not necessary that said adhesion promoter layer is required, an integral sanitary surface, such as made of an acrylic material, on the plate-like shower tray element 1 be upset. Instead of or in addition to the described adhesion promoter layer, a film cover serving also for this purpose may be provided. It may also, for example., If necessary, also act on the film cover to an epoxy resin coating. In particular, in the event that, for example, an XPS foam or a PU foam, so in each case a cellular foam and no particle foam, is used, can be completely dispensed with such a cover layer or adhesive layer.

In 1 For example only tile parts of a tiling are indicated.

In the central area of the shower floor element 1 is a drain grate 3 with a drain pot underneath 4 intended. To the drain pot 4 closes a drain pipe at the side 5 at. The drain grate 3 can also be formed elongated trough-like. It can also be a drain gutter.

Next is in cooperation between the drain pot 4 and the drain line 5 an odor trap provided. This can first by a ge suitable, not shown in the drawing chicane in the drain pot 4 be given. Next through the height-wise deflection, which is basically indicated in the drawing, the drain line 5 , By the latter, the odor trap is at least partially outside the drain pot 4 in cooperation with the drainage line 5 educated. The height-wise flow deflection given for this purpose is in particular on two deflection areas, the areas 6 and 7 , the drain line 5 due. The drain line 5 , as in more detail about 2 and also 4 results in this case runs in the entire shower floor element at a height of the pot bottom 8th or higher. In particular, when the pot bottom extends in the underside surface of the shower tray element. Overall, the drain line runs 5 within the thickness d of the shower floor element 1 in the mentioned leadership of the drain line 5 over different heights.

Of importance is also that the extension of the drain line 5 based on the formation of the odor trap, including including in particular the diversion 7 , over more than the simple, up to five or ten times a width b of the drain line 5 extends. In this case, the width is addressed by b, in the area adjacent to the drain pot to the beginning of the taper to the connection part 12 is given. This prolonged formation of the odor trap can also be expressed by, combined with or independent of the reference to the width b of the drain line that this area of the drain line 5 extends over a measure that is more than the thickness d of the shower tray element, in particular a measure that is up to five times, further up to ten times or more of the thickness d of the shower tray element. In this case, the disclosure also includes all intermediate values, in particular in 1/10 thickness increments (based on the thickness d of the shower floor element). This illustrates the substantial length of inclusion of the drain line 5 in the formation of the odor trap.

As can be seen from a synopsis of 1 and 2 is in the plate-like foam part 2 for receiving the drain pot and the anschießenden drain line an elongated through-hole 9 intended. The length of the through-hole 9 at least corresponds to the given dimension in this direction of the sequence, in particular the drain pot 4 and the length of the drain line 5 , which is used for the formation of said odor trap. Preferably also beyond.

Next is preferred, as in particular also from 2 that gives that opening 9 edge of the shower floor element by a remaining, so preferably integrally foamed wall 10 is completed. In the course of the preferred factory provided Voreindichtung the process including the subsequent drain line can this wall 10 as a plug-in wall for receiving a preferably via a respective end face 11 of the shower floor element 1 down protruding connecting part 12 be used the drain line. This facilitates the assembly and sealing. Further, the assembly and sealing can be facilitated by the fact that in the region of the grate and / or the drain pot and / or over the length of the drain line a Aufsetzstufe is formed in the shower tray element. Then the drain part, so in particular the drain pot and / or the drain line, come in accordance with counter-stage training in the course of insertion from above for placement. A fall down is prevented.

In an alternative embodiment, as in 3 is shown, are for the intended inclusion of the drain line in the shower floor element from the top accessible recesses 13 provided by the remaining wall parts 14 are interrupted. Preferably, it is at the recesses 13 around passage cutouts. The wall parts 14 allow a breakout and insertion of the drain line 5 from the top into the shower floor element. In particular, a plurality of such possible line guides can be provided in this way, so that a basic shape for the design of running in different directions drain lines can be used.

As in particular from the presentation according to 4 results, has the drain line 5 at least in sections a rectangular cross-section. Essential is a larger dimension of the cross section in the horizontal direction than in the vertical direction. It may also be, for example, an oval cross-section. Here is a dimension s of the drain line 5 less than the thickness d of the shower floor element, at least in the subsequent area of the shower floor element. In contrast, the already mentioned width dimension b at least in this area, but preferably also over the entire extent of the shower floor element, greater than the thickness d.

It can also be seen that the drain line 5 at least in sections over its length on the underside with a bottom surface 15 aligned. It is included in the floor design of the shower floor element. On the upper side, if necessary, in sections, an aligned course may be provided with an upper side of the shower tray element. In the embodiment, the drain line 5 on the top side by a cover plate part 16 covered. This cover plate part 16 lies on the edge of the foam part. Here in the area of a step education 17 , The drain line 5 is preferably integrated in the support structure of the shower floor element. This means that when a force acting on the vertical projection surface of the drain line, possibly reduced to this area, load the drain line contributes significantly to the stability. It has to absorb the corresponding burden. On the top of the drain pipe 5 or in the embodiment on the top of the plate member 16 the already mentioned adhesion promoter layer can be applied for the direct application of tiles.

With reference to 5 is clarified that a set-like composition of a drainage-containing base part and associated attachments 18 can be provided. Also such an attachment 18 can be provided with an adhesion mediator layer or optionally a serving film, in one of the embodiments as described above. It is particularly possible in an attachment 18 a drain-continuation 19 attached to a plug-like protruding connecting section 20 the drain line, with respect to the base part, may be formed. If, as is preferred, the base part is selected with a size that is usually not undershot, for example 70 × 70, 80 × 80 or 90 × 90 cm, it is regularly not necessary during installation to change the already pre-sealed section of the drain line again , Rather, the possibly the installation conditions owed special installation then alone in an attachment 18 be made.

In reference to 6 is a cross section through the shower floor element shown. The drain pot 4 is not formed to the bottom, the back surface of the shower floor element, throughout. However, this can nevertheless also be provided. In this case, the drain would be 5 also connect to the underside and not first make a curvature down, but first a curvature upward. In any case regarding the lower wall of the drain line 5 , The latter design is particularly favorable if, as preferred, already in the drain pot 5 a water level remains, so a part of the odor trap is completed. Here it can also be seen that the cross-sectional profile of the drain line 5 can change. In the front, drain pot near area, a rectangular cross-section is preferably provided. If this then merges into a round cross-section at the end, an increase in diameter is also preferred. Preferably, the drain line is 25% or more up to 100% of its extending in the shower floor element length range formed with a rectangular cross-section. However, it is also preferred that 5% or more of their respective length range is formed with a round cross-section. Also included in the disclosure are all intermediate values, especially with 1% increments. For example, more than 26% square and / or more than 6% round etc.

Instead of a drain line can also be to accommodate a certain amount of water NEN, in such a shower floor element - also preferably factory pre-sealed - several such drain lines in one of the described embodiments, which then preferably connect to a common drain pot, be provided.

Next is preferred, as is also out 6 shows that the already pre-sealed drain line 5 one from the edge 10 excellent male connector 12 having. In particular, when merging with attachments and here a further relocation of the drain line can be connected to this, without the Voreindichtung the drain line 5 would have to be touched in the base part.

Especially in this context is also a procedural Embodiment of the invention given.

The invention also relates to a method for forming a shower area, which is composed of a plurality of plate-like foam shower floor elements, wherein a base part and one or more attachments are provided in the base part factory already a drain and a drain line are sealed to form an odor trap , And further wherein the drain line associated with an edge of the base part in the base part has a terminal end and the installation adjustment is made only towards an attachment or that an adjustment is made only by separating the base part, without damaging the Voreindichtung. Installation adaptation here means cutting or separating such a foam part. The base part is this either in a (small) standard size, ie in various combinations always in the same size dimension, provided or in a large standard size, eg. The above mentioned 1200 times 1200 mm, so that in most cases only a reduction of the base part is required. In this case, no sealing connections with regard to add-on parts are required, although attachment parts can also be attached to such a base part of a large standard size. "Factory" means in connection with this application, on the one hand, that the possibilities of mass production are used, so that such parts are always practically the same, and / or on the other hand, that a shower floor element with such pre-sealed drain already by a plumber, at a dealer, especially wholesalers, can be acquired. The Voreindichtung refers evidently to the drain pot (edge with respect to the relevant opening of the shower floor element) and the preferably integrally formed drain line up to said terminal end and, as far as provided, beyond the Voreindichtung a drain line cross-over closure member, the closure of the shaft, in which the drain line extends, upwards, so in particular the described plate part. In addition, if necessary, a separate drain grate carrier (see cover 45 in 10 ). The latter also with respect to the seal in the shower floor element, but also with respect to the seal to the drain pot. A further subject matter in terms of the method is also a method for producing and assembling a shower tray element, the shower tray element having a drain, a drain line and an odor trap formed in the drain and / or the drain line, the drain line further having a connection end, and then further it is essential that the drain and the drain line, including the odor trap, are factory pre-sealed, the connection end is factory provided at a horizontal distance from the drain, whereby an at least partially upwardly open shaft into which the drain line extends, the connection end at already at an installation location on the floor resting shower floor element remains accessible from the outside for visual inspection, being further connected under horizontal mating assignment during assembly at a mounting location a flow-forwarding and auflie gendem shower floor element, the tightness of the connection of the drain forwarding is checked. The design of the shower tray element with a pre-sealed drain line and a non-deducted drain end, laterally to the drain pot, preferably, for example. A distance of one tenth to one third of the factory default size dimension, ie, for example, the width of 1300, 1200, etc. mm allows with respect to the connection of the drain-forward still required leak test in already resting on the floor and with the floor, for example. Bonded shower floor element at the installation. The shaft is then still open and it can be poured into the drain pot of water. With the eye, the junction of the pre-sealed drain line to the drain forwarding can be completely checked in so far just already lying at its final installation location and possibly anchored shower floor element. Thereafter, after visual inspection of the tightness, then the shaft, eg. In the already written way, can be filled and closed. It is essential also evident in this context that the design of the shower tray element with respect to the connection of the drain-forwarding a simple, horizontal plug or overlap mounting, for example. With a sleeve part allows. No vertical connection work is required. These possibilities and advantages also arise when a connection, possibly further connection, a flow forwarding in a on component is to be made.

Related to the 7 to 9 is a modified with respect to the expiration part embodiment of such a shower floor element shown and described.

The here integrated drain part, which also in the 14 and 15 is shown in detail, initially has a drain pot 4 in which an insert part 21 is used. This insert 21 yields along with the pot boundary, which here through the subsoil 22 the pot or the transition is given in the drain line, a first odor trap. At a first filling of the drain part results in a water level, before it enters the area after the first bottom hump 23 comes as indicated by the line L. Because this line L is above a bottom edge 24 of the insert part 21 runs, thus resulting in the region of the drain pot thereby a first odor trap.

It is essential with respect to such a drain pot 4 with insert 21 also the ratio of different water volumes given here. A first volume of water is in the insert 21 from the waterline L to the bottom edge 24 of the insert part. A second volume of water is in the drain pot 4 from the waterline L to its bottom, minus the first volume of water. A third, possible (refilling) volume of water is in the insert 21 from the now, for example, in 9 represented water line L up to the drain grate 3 given, including the radial magnification below the drain grate 3 and above the upper edge of the insert 21 , The drain pot is preferably formed so that the waterline L with the ceiling of the drain pot 4 extending radially outside the drain grate 3 is in normal condition coincides.

The size ratios of the drain pot 4 and the insert part 21 and the drain grate 3 , which results in said radial enlargement by its downwardly projecting edge, are preferably provided so that the first volume of water corresponds to one third to two thirds, more preferably half, of the second volume of water. In addition, the third volume of water is equal to or greater than the first volume of water, preferably in the range of 0.8 to 1.5 times the first volume of water. All interim values, in particular in one-tenth steps, are also included in the disclosure in the aforementioned water volume ratios.

It can be seen that the drain line is wave-shaped. In the cross section of the shower tray element it changes from bottom to top, back down and back up and then goes over into the connection part 12 ,

Until the transition to the connector 12 is given a significantly greater width b, see also 4 and 14 , as it corresponds to a free vertical opening dimension V of the drainage line between two humps.

In the area of the drain pot, the ceiling area is initially, starting from a the Aufsetzbereich for example, a drain grate 25 forming marginal edge 26 by a dimension × pulled down, the measure × corresponds to about one-third to half of the dimension V. The ceiling area then extends approximately horizontally so as to rise slightly in vertical overlap with the rise of the floor area and in the area of the first hump 23 then plateau-like 27 to get lost.

A central axis of the transition from the drain pot into the drain line, up to a region of the first hump, is less steeply rising than the associated bottom area. While the bottom region of the drain pot or the subsequent drain line in the region of the first hump rises approximately at an acute angle of 45 ° to a horizontal, a central axis in this area extends only at an angle of approximately 30 °. In then connect the sloping region of the first hump, however, results in a matching angle of the central axis with the floor area and the ceiling area. Here is enclosed with a horizontal approximately an angle of 40 °. Then follows a soil plateau 28 then to the second hump 29 proceed. Starting from about the ground plateau 28 the vertical dimension V expands somewhat but is again in the peak area of the second hump corresponding to that in the marked area. The connection cable 12 Obviously, it has a diameter about 3 times the dimension V.

The fact that between the two flow obstacles or humpback areas 23 and 29 the ceiling area of the drain is pulled down over the top areas of the hump, there arises - also - an odor trap.

The upper side is the drain in the opening area 30 the shower floor element initially exposed. This opening area is obviously also designed as a passage opening, wherein in the embodiment, only two bridges like remaining connections 23 . 29 are provided. Outside the area of the drain grate 25 is provided in the embodiment that a thin plate part 31 is provided for cover. This plate part 31 For example, a sheet metal part 31 be. It can also be a solid plastic part. It is further envisaged how this will turn out 10 that results cover 31 under a mounting land 32 the drain part can grab.

In this context, it is preferable that as out 10 seen, one a peripheral edge 48 of the mounting land 32 the annular cover 45 , Which incidentally belongs to the already factory pre-sealed parts described above, in cross-section U-shaped by a bead of adhesive 49 is included. This may be conventional adhesive, for example an MS polymer. In addition, since even more preferably a slightly lowered support edge 50 (see. 8th ) for the plate part 31 or a flange edge of the cover 45 is occupied with a preferably continuous adhesive bead, results in the connection areas edge, so the transition to the shower floor element, the desired complete, here three-dimensionally required sealing.

In reference to 11 is an arrangement of the drain part according to the 14 and 15 shown in a shower floor element with edge-side channel, as otherwise, with the exception of this expiry part, from the already mentioned above, not previously published European patent application with application number 09151299 is known.

As can be seen, the drain part extends almost exclusively in the area of the vertical height region Vx of the shower floor element forming the lower step-like projection. It can also here bridge-like or free-standing at randseitiger arrangement support sections 33 be provided. However, it is preferable in this context to work without such support sections. As can be seen, the drain part is arranged to run in a rectangular orientation to a gutter. It may therefore be provided on the edge side of the shower floor element and form as it were with an edge termination.

In particular, in addition to the insert part 21 a screw-in 34 provided, that for clamping against a floor area 35 of the following here to the gutter, as it were top drain pot, which is then supplemented by the bottom drain pot of the drain part, is used. Interposed between the top drain pot and the bottom drain pot is a circumferential, approximately wedge-shaped in cross-section seal 36 ,

The embodiments of the 12 and 13 relate to the integration of an expiry part, as described in the 14 and 15 is shown in a shower floor element, as it is known from the above European patent applications with application number 8168986 and 8168984 is known. Here arises from the well-known in this context bipartite between the upper part and lower part of a convenient installation option for the drain part in the lower part.

This with the reference number 37 provided lower part in the same way as in relation to 9 For example, the drain part is described. Only that the drain section here an inlet part 38 is assigned, which by the upper part 39 then compensates for additional height. In addition, in the embodiment of the 12 also on the cover by the part 31 according to 8th be dispensed with. Optionally, the bottom can also 40 of the top 39 be structured so that it adjusts the top side directly to the curved course of the expiry part.

At the subject of 13 is, as known from the above-mentioned corresponding European patent application, the sealing tape 41 in the lower part 37 integrated, ie factory-sealed, provided. Otherwise, basically the same conditions as before with respect to the embodiment of the result 12 described. In detail, this is a coating 43 on the lower part 37 provided, in which the sealing tape 41 is embedded. For further details, in particular, reference is made to the aforementioned European patent application. This may in turn be recommended, in the area of the drain part a plate part 31 to provide, which then also carries the said coating.

In particular, it is also preferable, both in the embodiment of 12 as well as in the embodiment of 13 that the inlet opening 43 in the sanitary surface 44 is arranged on the edge side relative to a base surface of the shower floor part and, correspondingly, the drain part also extends at the edge of the shower floor element.

Related to the 16 to 18 are yet other embodiments of the expiration part as such, as it can then be fitted into the described shower floor elements represented.

In the embodiment of the 16 are as it were two expiration parts according to 14 and 15 integrated against each other, but only a common drain pot 4 is trained.

In the embodiment of the 17 two such processes are shown formed at right angles to each other. This, as well as the subject of 16 , preferably in one-piece design. But it can also be two such drainage parts welded together accordingly. Also in the embodiment of the 17 is only an Ab running pot 4 intended. The drainage parts of the embodiment of the 16 and 17 obviously do not have exactly in the 14 and 15 However, they have one or more of the features described in this application for the sequence and a drain line.

In the embodiment of the 18 joins the drain pot 4 as can be seen on one side the previously described with the above flow obstacles design of the process, while on the other side, here at right angles to the first discharge part, immediately a drain pipe corresponding to the fitting 12 connects, so also directly from the drain pot 4 then provided starting.

For the drain part, as used here, in particular a drain part according to the 14 to 17 in one of the applications according to the 7 to 13 , in particular or in combination, in particular the following features are also important:
The bottom wall of the drain pot and extending between the two bosses of the drain line bottom wall extending on the same horizontal plane.

The largest vertical height of the first hump is higher than the largest vertical height the second hump.

The floor plan of the sequence is, in preferred one-piece design, such as a blown part, basically rectangular with a centrally on a narrow side projecting tube part, the addressed connection part 12 , It is understood that in spite of the also given there substantially rectangular design (outside the connection part 12 ) an edge rounding (inside and outside) is given. Preferably, the drain or the drain line made of thermoplastic material.

The width of the drain outside the connection part 12 is preferably twice or more greater than the height of the discharge part, the latter defined by the lower vertical plane in which the straight bottom regions given in cross section extend and the upper plane in which the upper wall extends in the region of the first projection.

The connection part 12 has a preferably substantially circular cross-section. Further preferably, it runs at a low angle, for example 1 to 10 °, in which case also intermediate angles, in particular in 0.1 ° increments, are included in the disclosure to the horizontal. As a result, it is also achieved, inter alia, that the necessary vertical clearance is provided in the edge region in order to carry out a connection to a continuation of the drainage pipe by means of a sleeve part, as is preferably done.

After seen in the direction of flow second hump is seen in cross-section, the upper wall continues horizontally or slightly increases until it in a horizontal wall (in cross-section, as I said, preferably a circular cross-section) of the connecting part 12 passes. The lower wall extends from the second hump down until they also horizontally into the wall of the connection part 12 passes. This wall of the connection part 12 is preferably vertically above the mentioned horizontal surface, in which the lower wall is in the region of the drain pot or between the two bosses. This vertical distance preferably corresponds to a half measure of V. The drop of the wall downwards in the transition region to the connection piece, after the second projection, is stronger than an optionally given rise in the region of the upper wall.

Contrary to what is apparent from the cross-sectional view, which is perpendicular to the representation in 15 in the region of the second boss, above, resulting flow cross-section greater than the inlet cross-section of the connector 12 ,

The drain pot 4 has an annular cover on the upper side 45 , see about 10 that roughly with the in 14 visible edge 46 can be welded or connected in any other way in the installed state. This cover is protruding outwards. It also forms the part already described 32 , Inside it forms a support edge, in which the already mentioned grid or other closure element can be accommodated.

The insert part 21 sits by means of protruding feet on the bottom portion of the drain, so that there can be a flow. It can also be pulled out of the drain pot, for cleaning purposes, for example.

All in all the drain part has a vertical extension over its total length, which is preferably 65 mm or smaller.

In the area of the drain pot, still closed continuation stubs can still be used in the exemplary embodiment 47 be provided, one or more of which may be opened if necessary and connected to lines.

The flow cross-section in the region of the first hump, the uppermost region of which is preferably smaller than the flow cross-section in the region of the following, second hump, also in the latter topmost area. It is also preferably smaller than each flow area that lies in between.

All disclosed features are essential to the invention (in itself). In the disclosure of the application is hereby also the disclosure content the associated / attached priority documents (Copy of the advance notice) fully included, too for the purpose, features of these documents in claims present Registration with.
