The drain channel and the drain line (5) are arranged on top of each other in a level. The base element is designed like a box and opened downwards. The drain channel is supported on a box cover. The drain channel and the drain line are arranged in a longitudinal extension. An independent claim is also included for an arrangement of a shower base element.

Description

The The invention relates to a foam shower tray element with a gutter, a pot bottom having drain pot and a höhenmäßig Flow deflection formed odor trap.

Foam shower floor elements, in particular in a plate-like design, preferably for the formation of floor-level shower seats, have already become known in various embodiments. It is for example on the DE 203 11 666 U1 directed. In addition, in particular with regard to sanitary surfaces or concrete shower trays, which have a downwardly facing Randabwinklung on the EP 2 060 217 A2 or the EP 2 060 377 A2 , 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.

In addition, on the EP 2 085 006 A2 directed. The content of this European patent application, in particular with regard to the described construction of the shower tray element and / or the gutter drainage system attached thereto, is hereby incorporated in full in the disclosure of the present application, also for the purpose, features of this European patent application in claims of the present application to include.

It there is a need for such foam shower floor elements to design as advantageous as possible in terms of the process. For example, with regard to a total construction height, the as low as possible. But also, in addition or alternatively, in view of a favorable pre-assembly, in particular regarding critical sealing transitions between Shower channel system and drain with odor trap. Further supplementary or alternatively with regard to a high drainage performance. Further in particular with regard to floor-level and floor-level installation such shower floor elements.

A first possible solution to this problem is through the subject matter of claim 1, with it being turned off is that the odor trap is at least partially outside the drain pot is formed and the height, for odor trap leading flow deflection at least partially outside the drain pot by means of Drain line is formed and that the gutter as well the drainage pipe forming the trap is stacked one above the other are arranged running. This means that in a cross section the gutter down to a gutter floor as it were in one first, upper floor is arranged extending and the drain pot with subsequent, formed by the drain line odor trap is arranged extending in a second, lower floor. Prefers Both floors are summarized, however, within an overall height the shower floor element is located. The shower floor element has thus prefers no elements, such as a pipe bend the odor trap or the like, on, the space below of the thus designed shower floor element would claim. Such a shower floor element can accordingly on a floor be installed without being with regard to the drain pot or the drain line or an odor trap formed thereby even a deeper recess in the ground than for the Overall shower element, the corresponding plate-like preferred is constructed, is required. This changes the drain line preferably in the lower floor over its longitudinal extent their total height, so runs in a side view snake-like to form the desired odor trap.

Essential for the invention is also, independently or in combination with the features described above, an embodiment according to which the shower base element is box-shaped downwardly open and the gutter sits on a box ceiling. In cross section is a practically U-shaped shower floor element created, that on its vertical side walls, the U-thighs, seated. The box ceiling or the U-bridge serves to accommodate the Gutter and the mentioned cavity, which, however, too still by transverse walls, but preferably only a part of the Cave cross section filling walls, can be divided and stiffened, for receiving the drain pot and the drain line. In this case, the box cavity extends preferably over the entire length of the gutter including the drain hole or the below located drain pot. Preferably also without interruption continuous.

Of the Drain pot and the drain line, at least up to one for continuation in the house drain pipe usable spigot are preferred within the box-like shower floor element, floor-level below the gutter, added. The box ceiling can, except for the required breakthrough to the drain pot, formed continuously be. But it can also be made of struts or part walls exist, on which the gutter, for example, only edge seated.

There is a shower floor element, which in terms of height by means of the integral boxförmi body with two, three or four sides running around the walls over two floors. Although such a shower floor element can still sit on a support element. But it can also sit directly on the floor or screed of a house. The edge walls can be comparatively thin walls which have only a thickness which corresponds to a fraction of the width of the gutter in their bottom area. But they can also be relatively thick walls, with a thickness exceeding the specified level, up to two or three times. In particular, it is also preferred that this thickness is different over the length of the shower tray element, wherein a thinner wall formation is preferably provided in the region of the drain opening than in the further region of the length of the shower tray element. In particular, when, as preferred, a drain line adjoins, which also forms at least a portion of the odor trap, this drain line is relatively wide in this area, according to said walls relatively thin. Starting with a region where the odor trap is completed, but then the width of the drain line tapers down to a circular cross-section, so that the walls are preferably made increasingly thicker accordingly. The different wall thickness results accordingly from the projecting into the interior of the box measure. On the outside, a single, given over the entire length of the shower floor element rectangular floor plan is preferred. A "thin" dimension of the wall thickness corresponds to about 1/20 to 1/3 of the width of the gutter in the floor area, while a "thick" dimension corresponds to up to two to three times the width of the gutter in the floor area. This in each case also including all intermediate values, in particular in 1/20 increments relative to the reference width, both for the delimitation of said areas from above and / or below as well as for the representation of individual singular width ratios or width dimensions.

It In particular, it has been found that the aforementioned floor-like superposition combines in any case, with a drain that at least partially the odor trap training leads to a surprisingly high drainage performance. This is attributed to the fact that due to the through the gutter given elevation of the water level above the entry level in the drain pot and / or through the gutter formation targeted to the drain pot supplied flow almost immediately gives a column of water and water, which is suitable, if necessary, in the deflections of the drain line immediately "flush out" the air volumes contained, whereby a very favorable, so to speak sucking course of flow is reached.

One such box-like shower floor element can initially basically with conventional drain pots and adjoining Be combined drain pipes. It can also be beneficial with an immediately adjacent to the drain pot drain line be combined in the following in more detail described manner at least partially an odor trap at the same time training, and which drain then home side with the house drain line (first) is connected.

at the embodiment in which the odor trap at least partially formed outside of the drain pot is particularly advantageous pre-assembly, in particular with the required sealing between drain pot, Drain line and gutter, factory already make. In further detail, the seal between drain pot and Drain line (factory provided drain line section, the for example at least partially also forms the odor trap) omitted if, as preferred, the drain pot and this piece the drain line are integrally connected.

Favor However, to the extent that the sealing assembly, at least then, if the drain pot and the said section of the drain line already in one piece with each other, first on site be made. The assembly is reduced so far on the Connection of the drain pot to the gutter for what an easy and safe-to-use sealing are used can. About to the tension of a at the gutter in this Area formed sealing collar between a screw insert and the drain pot.

Since further preferably the drain line with the preferably at least partially formed therein odor trap on the delivered to the site or there completed shower floor element is visible, as well as the further connection of this drain line section to the house drain line can by a technician on site Leak test be made readily. In particular, if the shower floor element, as also preferably provided, leaving usable in terms of its vertical walls as a viewing window outbreaks, but can also be easily cut on site. These outbreaks can be provided at the areas required for leak testing and possibly odor trap inspection, ie once in the region of the drain pot and on the other hand - at least - at the connection area between the factory-provided drain line and the house drain line. The leak test may possibly even be made with regard to the connection of gutter and drain pot before the shower floor element in Floor is installed.

It For example, a certain amount of water can be poured in and checked be sure that this is properly on the neck of the Drain pipe arrives without previous spout or, at the end of the month at the bottom, that too at the transition from the nozzle to the factory provided drain line to the house drain line a tightness is given without further ado. At the same time, the proper Training the odor trap by the necessary for this Water levels are visually inspected. This in the following, in particular, if, as preferred, the drain pot is integrally formed with the odor trap and / or the Drain pot and the corresponding part of the drain line transparent or at least are transparent.

in the Individual may at least partially forming the odor trap Drain line in a plan view of the shower floor element related on a longitudinal extension of the gutter in a right or acute angle to the gutter. Here is also preferred that the outside of a floor plan of the Gutter or, if applicable, outside the floor plan the gutter receiving foam shower floor element extending part of the drain line completely exposed is.

Especially however, it is preferred that the tiered one above the other running gutter and the drain line in a plan view overlap each other. More preferably in alignment, but with respect to the central axes of the drain line and the gutter offset each other.

One so educated two-story construction can be basically finished as an integral block in the factory put. With regard to a mounting at the installation is possibly only at a nozzle-like free end of the drain line the house-side Drain line to connect. However, preferred is how executed that in this respect made the final assembly on site becomes. Especially with regard to a pre-sealed integral training, but also with regard to a final assembly on site, has such a shower floor element, possibly with one or more of the training options described here, too Relevance with a standard square or round drain, without a gutter.

One As described here designed shower floor element can, for example, on practically the dimensions, at least in length, the gutter is limited (or possibly with regard to the dimensions a conventional gutter limited) as a combined gutter and Use drain line block. wide default is usually more than the width of the gutter, possibly as in the specific embodiment under consideration the additional width requirement of a laying part, the width of the drain line essential for the total width of this shower floor element. In any case, if the drain line at the same time at least partially the odor trap trains and for this as further below with more Detail described with an initially comparative large width is formed. The gutter and drain line block can with another shower floor element, possibly also in this Shower floor element composed of a plate-shaped upper part and one or more plate-shaped parts, in Juxtaposition, optionally also in insertion arrangement, be easily combined. This is then in particular of Advantage that the further shower floor element with regard to drain, Odor trap etc. must have no functional parts. In particular, in the case of a covering course from gutter and drain line no passage through this Shower floor element required. But it can also be an example enclosing receptacle in the other shower floor element be given, in which case the drain line as such, ie the house-side further drain line, without an odor trap training, through to the nozzle of the flow block adjoining area of the sibling or (partially) surrounding shower floor element passed must become.

The called shower floor elements are usually made of a Plastic, more preferably a foam, in particular a particle foam, as below explained below, produced. In that regard, anyway the gutter be included in such a foam part. As far as the drain line with the preferred in any case in part Training the odor trap not below, in coverage to the gutter, runs, it can project freely be educated. But you can also turn in a foam part be included, the drain line in particular the top side, preferably only on the upper side, covered. Here, this receiving Foam part for the drain line stepped be offset to a surface of the gutter, which Surface usually by one of the user then to be entered drain grate or the like. Is formed. The step-shaped Absetz can be provided, for example, that by means of a Tiling then the flatness can be produced.

In the embodiment in which the drainage channel and the drainage line are provided running in the same direction of extension one above the other, both components are in the same Foam part added. The foam part can be formed here as a downwardly open box, optionally with one or two transverse partitions. This open configuration also allows in particular the said visual inspection during installation on site. At the box ceiling, the gutter can rest or be supported.

in the Regard to the already mentioned possibility of a Visual inspection of the tightness can be mentioned in the Side walls, in particular one or both sides in the Long sides, breakthroughs, such as arcuate Breakthroughs, provided or by grooves for breaking out be predetermined.

A Mouth of the drain line or a free nozzle, to the then connect the other drain line at the house side is preferably, a narrow side of the flow block faces educated.

Especially it is preferred that said mouth of the drain line, So the mentioned nozzle, on the one hand, and the drain pot or the drain opening in the gutter, on the other hand, opposite Sides of the flow block thus formed are arranged assigned.

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 the area 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 line and possibly also one in the drain pot itself already provided flow deflection baffle, remains in the pot or said deflection a certain water level are preferred, thus already a part of the Ge faucet closure 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 in terms of preferred housing is displayed in the thickness of the plate-like shower tray element 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.

Especially it is preferred that the drain line is wave-shaped. This means that the drain line in a longitudinal cross-section, a cross section in the flow direction, total upwards and changing at the bottom. "Total" means in this case, it is preferred that the elevation change of such magnitude is that after changing a duct bottom in a horizontal plane or above a ceiling extends before the change. This with a rise angle and a Descent angle. The rise and / or fall angle is preferred chosen in the range of 35 to 55 °, in particular 40 to 50 °. Here are the angle data related to the course of the subsoil in vertical cross section of the drain line. The topsoil or ceiling area the drain line may have lower rise and fall angles, this is also due to the fact that it is in the range of altitude Change to a cross-sectional reduction of the line can come. Relative to a central axis is the rise and / or descent angle therefore preferably in the range of 20 to 40 °. In terms of The specified degree range specifications are also all intermediate values, in particular in 1 ° steps, included in the disclosure. In any case It can be seen that the rise and fall angles are preferred are 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 ground floor formed soil flow obstacles 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 then the only through the drain line, outside 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 bottom flow obstacle here represents with its rising edge at the same time the conclusion of the drain pot. The descending flank is part of the formed in the drain line odor trap. The subsequent second soil flow obstacle complements with its rising edge, the descending flank of the first soil flow obstacle and continues to form so in cooperation with the opposing Deckenbuckel the odor trap within the drain line. The descending flank of the second Bottom flow obstruction also forms the transition into 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 is the thickness of the shower floor element or at least the thickness of the discharge line associated floor exceeds the shower floor element. The thickness of the floor is hereby preferably only by the largest Vertical dimension between line bottom and cable ceiling in the area the odor trap training in the drain line given. It It is understood that the concrete, this measure forming Areas horizontally offset from one another can be arranged. However, this thickness of the floor can also exceed the said measure. For example, up to 50% of the mentioned largest Vertical dimension, whereby also in this regard all intermediate values, especially in 0.5% steps, are included in the disclosure. The Floors preferably have no same thickness. The thickness of the upper Floor is preferably less than the thickness of the floor, in which the drain line extends. So the thickness of the lower floor, in which the drain pipe extends, in the range of 70 mm or less, in particular up to 30 mm. The thickness of the upper Floor can also be, for example, 70 mm, but preferably clearly less. Up to about 10 mm. In the mentioned thicknesses The floors are hereby also all intermediate values, especially in 0.5 mm increments, to restrict the areas from above and / or below or also for the presentation of individual values from the field included in the revelation.

in the Individual is also important that preferred in the drain line no check valve is provided. Hereby, on the one hand the desired high flow also again supportive be ensured. On the other hand, there is enough compensation space created a possible repression of the Balance water column. A high flow rate, optionally regardless of whether a non-return valve is provided, is also given by the fact that the curvature with formed at such a shallow angle that in the upper Areas remaining in normal use certain flushing, using a corresponding Shower, become air-free and so a self-priming water column which additionally supports the performance of the drain increases. It is preferably not part of the whole Drain system of the shower floor element, the 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. Preferably, the gutter outlet sits directly on the drain pot. 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 optionally formed with a slightly smaller vertical extent is a gutter be set up so that the gutter floor immediately opens into the drain pot.

Prefers has the drain pot, for example, a round, square or rectangular plan, a maximum dimension in Reference to a horizontal extension which is a fraction of the Total length of the gutter corresponds. In particular one-tenth to half the total length of the Gutter. Again, all intermediate values, in particular 1/100-steps of the length of the gutter with respect to the said measure in the disclosure included.

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. The Shower floor element can in this context also the gutter be receiving shower floor element and / or the associated further Shower floor element.

Since the ground flow obstacles in cross-section at the same time form bridge-like elements, they can also be advantageous by appropriate Durchgriffsverbindungen the shower floor element be understood. This penetration connections can be formed integrally with the shower tray element, and more preferably from said foam, at the same time. Viewed between two Durchgriffsverbindungen, in the direction of flow, then results in a window-like opening in which down the drain line odor trap forming bottom portion of the drain or the drain line can be exposed.

The mentioned bridge-like training in the field of flow obstacles is also advantageous in terms of stability. It provides a vault structure that can contribute favorably to the overall stability of the process and also floor element with clamped drainage. In this case, it is also of particular importance that the extent of such a vault, ie from bottom section to bottom section, is about 1 to 3 times, preferably 2 times, whereby here also all intermediate values, in particular in 1/10 steps, in the disclosure is included, the thickness of the shower floor element or the floor in which the drain line extends corresponds. In the here also preferably provided installation of the described sequence in an article according to the European Patent Application Publication No. 2085006 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 process can be installed in the lower plate part, for example simply by inserting it from above, and the upper plate part can then be provided so that it not only has no function but also no design feature with regard to the procedure. So, for example, no cavity or Ausbrechwände or the like. Are provided.

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 line 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 the shower floor element or the floor of the shower floor element, within which the drain line runs, surpassing Has 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, can be This also in the areas in which the drain line in the upper or lower surface of the plate-like shower tray element For example, the floor included, a cheap Reach surface support.

The Drainage can also be at least over a partial length the thickness of the shower floor element or the thickness in any case one correspond to the floor described here. At least about this Part length is the shower floor element in this area in Thickness direction formed solely by the drain line.

In the previously mentioned embodiments, in which the drain line runs almost completely or flush with an upper side or a lower side surface of the shower floor element or at least one floor of the shower floor element described here, the drain line is also integrated in the support structure of the shower floor element. There are such surface elements of Ab line exposed or at least provided without an integral connected to the shower floor element incidentally foam covering, that - relative to the upper surface of the plate-like shower floor element - with small tiles, for example, have an area of 1 cm ² or more, for example down to 25 cm ^2, a Tile is only within a Verti kalprojektion 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 can, for example (Only) in the area forming the upper floor or the space provided therefor be formed separate plate part. The passage opening can be over a third in length or more, approximately on a rectangular ground plan, one Longitudinal side of the shower floor element extend. in this connection is preferably the drain pot or over it Drain grate arranged approximately centrally of the plate-like shower tray element. This, because due to the described design of the drain line with regard to the formation of the odor trap a certain Length extension of the drain line alone to form the odor trap is used. This length extension, which is used to form the odor trap, can about the Two to ten times the largest diameter of the Drain line. This also includes any intermediate values, especially in 1/10-diameter increments, in the disclosure with included. The reference to a largest Durchmessermaß is particular then important if, as preferred provided, the drain line at least partially and preferably in the area in which - 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 rectangular, more preferably with a taper towards the edge. The taper can be provided in such a way 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, especially if the drain line in a related Floor of the shower floor element runs, 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 area 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 may, 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 is still provided with a foam wrapper, for example a soft foam wrapper, approximately as one generally knows from the jacket of heating pipes. Further preferably such that stomata up to a bottom of the shower floor element or, in the passage opening of the shaft, up to a floor on which the Shower floor element is installed during assembly, remain. 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. Furthermore is preferred, as stated above, that this Dimension is also applicable to the measure of a floor. In the case of a two-layer structure, it is accordingly preferred that the total thickness 140 mm or less. On the other hand, it is preferable that the thickness of the shower floor element or a floor, at least the lower floor, 30 mm or more. This is further to take into account that the thickness in the edge area is greatest is, as a rule, a slope to the process towards the top the shower floor element is formed. The gradient can in a shower floor element with an edge dimension of, for example, 1.2 1.2 m to a centrally planned drain 15 mm. Therefore, the thickness of the shower tray element, based on the edge side 70 mm, in the area of the direct connection of the shower floor element to be specified on the drain pot with, for example, 55 mm. As far as a floor is addressed, is the lower floor, in which preferred - only - the Drain line preferably extends with the same thickness throughout educated.

The here given ratios in relation to the thickness of the Shower floor element or a floor are, if not in individual cases something else is stated, always on the biggest Thickness in the outer edge area related.

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.

A preferred embodiment of the shower floor element is in the sense of the next Given above gutter block or integral block.

The aforementioned embodiment of a plate-like shower floor element is particularly advantageous in terms of the formation of a shower place composed of several plate-like shower floor elements. Here, however, preferably only one, more preferably a peripheral or central, shower floor element said drain with subsequent drain 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 having base element. Next from one or more attachments. The preferably factory pre-sealed drain line, including the drain pot, which is also preferably integrally formed with the drain line, can conclude with respect to a connection end for a to be connected during installation on-site drain forwarding with a peripheral edge of the base element. However, said connection end can also protrude like a plug from the base element. In addition, it may be set back with respect to the peripheral edge. In the case of the recessed arrangement is particularly preferred that the terminal end is set back below a cover plate. With regard to the drainage channel, it can also be set back to below an end region of the drainage channel. The cover plate or the ge called end of the gutter ends in this case preferably at a distance from the peripheral edge of the base member. In this context, too, this basic element is to be equated in particular with the mentioned channel block or integral block. Also, the terminal end may terminate flush with the edge of the cover plate or be recessed further below the cover plate. The drain line can then be continued by connecting a drain forwarding, which is preferably by simple horizontal connector, possibly by means of a cross-sleeve, in the base element or a mounting element. For this purpose, it is also possible to cut or fill out predetermined or freely selected openings, for example also predetermined outbreak openings. The assembly of the base member with one or more attachments may be provided butting abutting. Here can be achieved on the upper side, for example by known sealing tapes or films, the sealing. However, it can also be provided a tooth-like meshing of edge portions of the base member and the attachment or the add-on elements, which are prestructured corresponding edge side. Also in such a case can complement a seal the resulting joint area by a covering sealing tape or a covering surface covering sealing foil, possibly be provided with edge overhang for connection to the surrounding soil or masonry.

The Attachments can be formed in particular like a bolt be, so with rectangular plan and preferably also rectangular Cross-section. Here they are more preferred in a set, ie summarized or as additional parts for a here described Shower bottom element, provided such that at least one of the locking elements the marginal edge length of Duschbo denelementes exceeds. So can be bluntly abutting Corners are formed with the attachments.

in the Another is also the shower floor element, as it described here, low in terms of space adapt, in particular by separating parallel to the drain line, accordingly offset laterally thereto, or in an area of the the extension of the drain line is opposite.

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.

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 upper side, possibly also on the front edges, possibly also on the underside, the foam element is 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 be organic and / or mineral filler contents. The primer layer may also be made of a plastic-mortar combination consist. These include in particular mixtures of hydraulic setting binders (eg Portland cement). These may be mineral aggregates and / or organic Have additives and / or polymer dispersions as a proportion. In addition, the coating may also be from another Mortar coating exist.

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, ie each unicellular 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 suitable, not shown in the drawing harassment in the region of 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, which is adjacent in the area to the drain pot at the beginning of the taper to the connector 12 is given. This prolonged formation of the odor trap can also be expressed in combination with or independent of the reference to the width b of the drainage device 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 subsequent 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 protruding connecting part 12 be used the drain line. This facilitates the assembly and sealing. Next, 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 touchdown is formed in the shower floor 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 in 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 may be provided with a primer layer or optionally a film serving for this purpose, 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, how Preferably, the base part is selected with a size that is usually not fallen below, about 70 × 70, 80 × 80 or 90 × 90 cm, it is regularly required during installation, not 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 added to a certain amount of water to be able to record in such a shower floor element - also preferably factory pre-sealed - several such Drain lines in one of the described embodiments, the 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 with respect to 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 respect to attachments are required, although attachments are also grown on such a base part of a large standard size NEN. "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 essential is that the expiration and the expiration line, including the odor trap, are factory pre-sealed, the connection end is factory provided at a horizontal distance to the drain, according to an at least partially upwardly open shaft in which the drain line runs, the connection end resting already at a location on the ground Shower floor element remains accessible from the outside for visual inspection, which is further connected under horizontal plug assignment during installation at a mounting location a drain forwarding and denied Duschbo denelement 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 sequence forwarding is to be made in an attachment.

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 x pulled down, wherein the dimension x corresponds to about one-third to half of the dimension V. The ceiling area then extends approximately horizontally to slightly increase in vertical coverage 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 the subsequent sloping region of the first hump, however, there results a coincident angle course of the central axis with the bottom region and the cover region. 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 shows that the 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. Zwischenge switched 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 just a drain 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, inter alia, it is also achieved 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 half a measure of V. The drop in Wan Downward in the transition region to the fitting, after the second hump, is stronger than any increase in the upper wall area.

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.

Of the Flow cross section in the region of the first hump, the uppermost Range, is preferably smaller than the flow area in the Area of the following, second hump, also in its uppermost Area. It is preferably also smaller than each flow cross-section, which lies in between.

Also in the embodiments of 1 to 8th and 12 to 18 may also be provided in each case a gutter instead of a round or square drain.

Related to the 19 to 24 is the construction of a shower area consisting of a shower floor element 50 with gutter 51 and an adjacent or surrounding arranged, with respect to the sequence preferably functionless shower floor element 52 illustrated and explained. The as long as elongated block-like design shower floor element 50 is a to the dimensions of the gutter 51 adapted elongated shower floor element with gutter included therein 51 and drain pot formed therein 4 with subsequent drain line 5 , at least partially in the drain line 5 also the odor trap is formed.

The shower floor element 50 is two-tiered, wherein the first floor I corresponds approximately to the dimension Vx, which is already in relation to 11 is explained. In this floor I extends inside the drain with integrated drain pot 4 and drain line 5 , wherein in the drain line 5 as already described, the odor trap is substantially formed. In a connection area 53 is a redirect piece 54 Being in a free neck 55 ends, connected. At the free neck 55 can then be connected to the other house-side drain line. But it is also possible, for example, the further drain line already at the connection area 53 to join. The part 54 can be removed for this, if it is already preassembled, for example, simply cut off.

The shower floor element 50 has on the outside preferably on all four sides, but in any case on two sides, down to a continuous apron-like wall 56 on. This wall 56 preferably also serves (alone) as a supporting wall element on which the shower floor element 50 gets up. The foam part of this block-like shower floor element 50 is further preferably formed box-like, wherein on a ceiling, which may be at least partially open so far, the gutter 51 sits or sits down. The box is open in the manner described below, see in particular also 21 , For receiving the gutter 51 is the elongated block (with) forming foam part in a cross section transverse to the longitudinal extent or in an end view also formed stepwise. Facing the in the illustrated embodiment, the shower tray element 52 facing longitudinal side, the foam part extends to the surface, with the exception of a cover layer 57 as a surface coating, in particular for receiving tiles also in the shower floor element 52 is provided in a known manner.

The Ceiling of the foam part with gutter here forms the second Floor II. The thickness of the second floor II is preferably clear less than the thickness of the first floor I. The thickness of the second floor II corresponds to about 1/20 to half, if necessary but also up to the entire thickness of the thickness of the floor I. In this Thickness ratios are also all intermediate values, both for delimiting the said area from below and / or above as also for the representation of single singular ratios hereby included in the disclosure, especially in 1/20-thickness increments.

The gutter 51 is further elongated, practically over the entire length of the block-like element 50 formed extending. In the larger length range with a width which is less than half the width of the integral block, preferably 1/20 to 1/3 of the width of the integral block, whereby also all intermediate values, in particular in 1/20-width steps hereby are included in the disclosure, both for delimiting said area from above and / or below, as well as for representing a singular measure or ratio. In one of an end face of the block-like element 50 facing area, however, a broader enlarged area is provided, namely associated with the drain pot 4 , This width of the gutter here corresponds to 1.1 to 3 times the width of the gutter, moreover, in the same way here, especially in 1/10 steps, the intermediate dimensions are included in the disclosure. The absolute dimensions of the integral block may be, for example, 700 to 1800 mm in terms of the length, for example 100 to 400 mm in width. Here, too, all intermediate values, in particular in increments of 1 mm, on the one hand to delimit the areas mentioned from below and / or above on the other hand, but also to represent individual absolute values within the ranges, are included in the disclosure.

A gutter floor 58 delivers directly in and is connected approximately evenly to an upper edge 59 of the drain pot 4 ,

The formation of the odor trap in the drain line 5 outside the drain pot 4 extends about 1/5 to 1/2 of the length of the block-like element 50 in the longitudinal direction of the drainage channel 51 Again, any intermediate values, in particular in 1/20-length increments of the discharge line, both for limiting the range from below and / or above as well as for representing individual intermediate values, are included in the disclosure. The width of the process block 50 is to the width of the drain line 5 adapted in the area of the odor trap. It exceeds the width of the drain line in this area by a little. About the extent to the formation of the walls 56 , which have a thickness of 1 to 10 mm, including any intermediate values here as well in the described manner, in particular in 1/10 mm increments.

The box-like open structure of the integral block 50 can be by transversely extending one or more partitions 60 , see for example 22 Be strengthened. The drain line 5 penetrates one or more of the partitions 60 ,

The gutter 51 is further in detail on the upper side by a gutter edge with forming support part 61 formed, which at the same time a gutter edge 62 formed. This edition part 61 assigns to the drain pot 4 a preferably integrally formed downwardly projecting engagement 63 put it in the screw socket 64 of the drain pot 4 intervenes. Upper side can be a frame 65 to be in the mood. The height of the fold serves to subsequently on the support part 61 Tiles, which then compensate for the height. The further gutter edge 67 runs flush with an outer surface of the relevant wall 56 of the block-like element 50 ,

As further in detail about 21 can be seen forms the gutter 51 in the area of the drain pot 4 an integrally molded sealing collar 68 out. The sealing collar 68 is between a so far outwardly visible upper edge 59 of the drain pot 4 forming screw 69 and an upper termination section 70 of the drain pot 4 with the interposition of a circumferential seal 71 braced. The part 70 forms a mating thread to the external thread of the Einschaubteils 69 , The part 70 is for one-piece with the other part of the drain pot 4 welded.

At the screw-in part 69 are also assigned to the edge 59 handling projections 72 formed, which facilitate the insertion and tensioning.

Inside the screw-in part 69 is the insert part already described earlier 21 used.

As can be seen in particular 22 results, it allows the said mounting option due to the one-piece design of the drain pot 4 with the subsequent preferably already provided part of the odor trap subsequent factory-provided drain line 5 not only a simple assembly, but also a floating arrangement. The drain pot 4 and the subsequent drain line 5 , Where appropriate, also the extension piece and the house side subsequent drain line can, with a distance a, which can vary over the length, to the ground 73 (home side) in the relevant shower floor element 50 be arranged.

In connection with the here, for example, arcuate outbreaks 74 in one or both of the longitudinal walls 56 Visual inspection possibilities for a leak test also arise even with a built-in shower floor element 50 , Due to the floating arrangement, a control element, such as a sheet of paper or the like can be pushed in to detect any leaking water.

Of further importance is the surrounding at the gutter part to the drain pot enlargement forming wall area 75 trained bearing surface 76 , The bearing surface 76 surrounds the wall 75 as horizontal flange or the wall 75 goes over here. In particular, associated with a front side of the shower tray element, as can be seen from the perspective view according to FIG 23 also yields, is so marginally created to the drain pot associated channel enlargement still a surface that can be tiled.

A similar purpose is served by the already mentioned final part 66 , On the one hand, it can be inserted into an end region of the gutter opposite the drain pot and thus form a surface that can be tiled over. On the other hand, but also the gutter edge can be formed at this end with the same flange-like overlap as already explained with respect to the area associated with the drain pot.

Since, however, the shower floor element at the end of the channel, on which the end opposite the drain pot, can be separated, the result is an open channel after separation. Here is in the groove and the said part 66 in order to create a degree and immediately create a floodable area.

In reference to 24 are possible overall arrangements of the shower floor element described here 50 with respect to an adjacent or surrounding shower floor elements. With the exception of 24g and 24 hours is in each case a top view reproduced from above, before tiling and without the support part 61 , The knotted-dotted line with arrow direction L indicates the course of the drain line and the possible continuation with regard to the house-side drain line.
