Description

The invention initially relates to a method for creating a shower tray construction according to the features of the preamble of claim 1.

Furthermore, the invention relates to a shower tray construction according to the features of the preamble of claim 7.

Methods of the type in question are known. These serve, for example, for producing a floor-level shower tray structure, i. Shower trays whose useful surface is at least approximately fitted into the surrounding floor level.

Moreover, such shower tray assemblies are known in the art.

The state of the art is first on the DE 197 04 950 A1 to refer. From this, a shower tray construction according to the preamble of the device claim 6 and a method according to the preamble of claim 1 is known.

In addition, is also the DE 20 2006 016 895 U1 to refer. This shows a one-piece carrier base with edge protruding foil.

Based on the cited prior art, the invention is concerned with the task of specifying an advantageous method for creating a shower tray structure and an advantageous shower tray construction.

The invention is procedurally achieved in the subject matter of claim 1, wherein it is employed that the trough shape has an edge and that initially the trough shape until at least including the edge on or foamed, and that then the on or foamed pan shape, wherein the foam body produced by the on or foaming forms a carrier shell, is connected to a separate, a marginally protruding sealing tape having carrier base.

The invention is device-solved in the subject matter of claim 6, being based on the fact that the trough shape has a Randabwinklung and that the support member is formed in two parts, wherein a separately formed carrier base is provided with a peripheral sealing tape, which is captively connected to the lower carrier part ,

The tub shape is procedurally up to the edge, preferably initially up to and including the plane of the Randabwinklung on or foamed and then the foamed pan shape with a separate, the edge side protruding sealing tape having carrier base connected. Here, the foaming, in particular in the case of only a slight edge angling or a flat edge, also be provided (vertically) beyond the plane of Randabwinklung addition. It is therefore given a method which allows the flush mounting of any tub shapes, especially those with Randabwinklung. In particular, in the case that only a slight Randabwinklung or a planar edge-side leakage of the trough shape is given, which takes place beyond the plane of the Kantenabwinklung out foaming or foaming with respect to a portion of the full height of the shower tray construction is performed. For example, one tenth to two thirds of the height of the complete Shower tray construction. The remaining area is then formed by the carrier base. In the case of a Randabwinklung the underside of the Tannenform-Nutzseite by the Randabwinklung limited space is possibly completely filled with foam.

The foaming or foaming takes place further considering a drain and / or a drainage recess or a preparation for this for the tub shape. Thus, in principle, an internally open but externally circumferentially closed foam body may be formed.

If the foamed body produced by foaming and forming a carrier top part extends beyond the plane of the edge angled portion, the standing surface of the carrier top part considered as such is height-wise spaced from the circumferential marginal edge of the edge angulation.

The peripheral sealing strip or the individual, each side of the trough shape associated sealing bands are captively connected to the carrier base, so for example. Surface side of the carrier base glued to this. Trough shape and produced by foaming carrier shell form a structural unit. This means that they are only destructive, usually by tearing open the foamed foam, are separable. This unit is factory, but also possibly on site side connected to the carrier base, which is preferably adapted to the base surface to the carrier top. Preferably, an approximately full-surface support is achieved.

The preferred at least a portion of the drain, so in particular a odor trap portion and a drain line having support base also serves as a spacer for raising the carrier shell with the tub shape on finished floor level, further the connection of the On the edge side protruding sealing tape on the composite shower tray structure in the connecting plane between the carrier shell and the carrier base and thus spaced apart from the circumferential edge of the Randabwinklung the trough shape is formed. Carrier base and carrier shell are connected to each other at least in the installed state, so for example. Bonded, this more preferably the entire surface. In addition, as an alternative or in addition to such an adhesive connection, a positive connection between the upper carrier part and the lower carrier part can be provided.

The main idea of the application is the (at least) bipartite of the carrier, wherein a first part is connected by foaming or foam backing with the trough shape and a second part forms a carrier base, wherein further the sealing tape either already on the trough shape or the carrier shell or by the carrier base is integrated. With regard to the trough shape, it can also be a conventional bathtub shape, that is to say also a bathtub structure.

In an advantageous development of the subject invention is provided that the foaming is carried out by means of a polyurethane foam, which foamed body then forms the carrier shell. In any case, for foaming, even a desired waterproofing foam is preferred. The carrier lower part preferably consists of a particle foam and preferably has a density in the range of about 25-110 kg / m ³ . Here, especially at very high densities, ie 60 kg / m ³ or more, in particular 80 kg / m ³ or more, even a directly resulting water resistance, in this case especially of the carrier base achieved. Thus, further, the carrier lower part of a particle foam such as EPP or EPS exist. In addition, also out Foams such as XPS (extruded polystyrene foam) or polyurethane foam.

In the event that the carrier shell and / or the lower carrier part are formed with an inner cavity, a foaming of this cavity is preferably carried out. The foaming of the cavity is made in a development of the subject invention with different densities, this further using a common base foam, namely poly-urethane. The foaming of the zones of different density can take place one after the other. It is conceivable in this regard, a simultaneous foaming. It is thus preferably provided that a foam of higher density is provided in an edge area, if appropriate, of the trough-shaped edge angling, than in the central area. Thus, for example, the region of higher density can be made by foaming with a polyurethane foam having a density of 60-100 kg / m ³ , while in the central region of the trough shape, a polyurethane foam having a density of 6 - 30 kg / m ³ application. This may be a polyurethane reaction mixture which foams with application virtually simultaneously.

It is further preferred that the trough form is completely filled with foam, possibly only leaving a free space for the drainage. Accordingly, the trough shape is supported with - at least approximately - the entire surface on the carrier top part thus created from. Next cavities are thereby avoided. In a further possible incomplete foaming of the trough shape, the remaining cavity is more preferably filled by a portion of the carrier base.

The sealing tape or the individual sealing tapes can be glued to the carrier base. Next there is the possibility that the sealing tape in a on the carrier base or the carrier shell applied sealing compound is inte-grated. This may be a plastic mortar dispersion or a dispersion seal.

In terms of equipment, the upper part of the carrier is simultaneously arrested by the foaming with the trough shape. Both parts, the trough shape with the carrier shell, thus form a mounting element, which is thus assigned to the separate carrier base. Its height is chosen according to the given overall height of the shower tray. The foaming to form the carrier shell is preferably factory. After that, the assignment of the separate, the edge side protruding sealing tape having carrier base can be made. Alternatively, this happens only on site. The formation of the Hinterschäumungsteils by foaming on-site for example, can be done by penetration of local foam. The carrier lower part continues at least one drainage recess or a preparation for this and / or the drain for the shower tray, so for example. In the form of an odor trap portion and a pipe discharging therefrom. The foaming of the trough shape for forming the carrier shell is further preferably made so that the created foam body completely or almost completely covers the trough form on the underside, ie fills the cavity bounded by the trough shape in the case of Randabwinklung. This possibly while leaving a free space for the engagement of a part of the drain, so on, for example, the carrier lower part side provided odor trap section. After the carrier lower part has been assigned to the upper carrier part, the sealing tape fixed to the lower carrier part is at least level spaced from the free end edge of the circumferential edge bend of the trough shape, at least with the fixing section not projecting at the edge. The sealing tape is in this case captively attached to the carrier base.

The sealing strip is intended to be provided as a circumferential, laterally projecting band, which is fastened to the carrier lower part body by the cross-sectional end region assigned to the central region of the carrier lower part. Also can each per-carrier lower longitudinal side, ie four ordinary sealing strips are provided in the usual square floor plan design of the shower tray, which overlap in the corner regions of the trough shape in the region of its edge protruding portions. Alternatively, there is also the possibility that the sealing tape is a partial area of a nationwide sealing film. Such a sealing foil has a ground plan dimension which exceeds that of the carrier lower part, to the edge-side projection of sealing strip sections. This continuous sealing film is preferably the entire surface on the carrier top part facing surface of the carrier base connected to this, so further preferably glued. This further possibly only interrupted in the region of the carrier lower part upper side in the direction of the carrier upper part passing through the discharge section. It can also be a frame-like sealing film.

The separation between the carrier lower part and the carrier upper part is preferably provided along a continuous horizontal plane. Accordingly, the carrier top is preferably in a horizontal plane over the entire surface on the carrier base. The sealing strip or the sealing film in this case extends in a plane which is distant from the free edge of the edge bend, namely further in the parting plane between the lower carrier part and the upper carrier part. Alternatively, the separation between the carrier lower part and carrier upper part in the sense of mutual engagement of the parts is given, for example by a spigot connection or by step-shaped form-locking connections, whereby a position assurance of the parts is achieved in the horizontal direction. In the overlap region to the sealing tape, the separation between the carrier base and the carrier shell is preferably also in the alternative design in the region of a common horizontal plane.

In an advantageous development of the subject invention, it is provided that the foaming carried out by means of a polyurethane foam which foamed body then forms the carrier shell. The carrier base preferably consists of a particle foam, preferably has a density in the range of about 25-110 kg / m ³ . Here, in particular at very high densities, ie 60 kg / m ³ or more, in particular 80 kg / m ³ or more, even a directly resulting water resistance of the carrier base is achieved. Thus, further, the carrier lower part of a polystyrene foam particles such as EPP or EPS exist.

The foaming of the cavity is carried out in a development of the subject invention with different densities, this further using a common base foam, namely polyurethane. The foaming of the zones of different density can take place one after the other. It is conceivable in this regard, a simultaneous foaming. Thus, it is preferably provided that in the marginal, the Randabwinklung facing area a foam of higher density is provided as in the central area. Thus, for example, the region of higher density can be made by foaming with a polyurethane foam with a density of 60-100 kg / m ³ , while in the central region of the trough shape, a polyurethane foam with a density of 6-30 kg / m ³ applies. Accordingly, the density of the foam area of higher density approaches the volume weight of the carrier base.

In a further alternative embodiment, the sealing tape can also be anchored in the carrier base, for example by foaming a fixing area in the course of the production of the lower part.

It is further preferred that the trough shape, if appropriate only leaving a free space for the drain, is completely foamed. Accordingly, the trough shape is supported with the entire surface on the carrier top part thus created from. Next cavities are thereby avoided. This can be further achieved even if the tub shape is not completely filled, especially in the central area is not completely filled. Here, the cavity is then preferably closed by a correspondingly raised portion of the carrier base.

The two support parts can be glued together in the form of a positive connection both in a separation along a continuous horizontal plane and in mutual engagement, preferably in the region of mutual engagement. This bonding can already take place in the course of production. Alternatively, it is also possible to make this bonding site site site. In addition, the carrier lower part may have a coating. This may be a polyurethane layer, which is, for example, rolled up.

Illustrated and described first with reference to the illustration in Fig. 1 a substantially consisting of two possibly only on site site composable parts existing shower tray assembly 1. This first has a the shower base forming trough shape 2. This is square in shape and provided with a circumferential, integrally formed with the tub molding surface 4 edge bend 3. The trough molding surface 4 is inclined starting from the edge-side transition into the edge bend 3 toward the middle in the direction of a central drain opening 5.

The edge bend 3 extends in a cross section through the trough shape 2 at right angles to a plane defined by the Tannenform-edge edges horizontal plane E. It can also be given an angling which intersects the horizontal plane in an imaginary cross-sectional edge extension only at an acute angle. It can also be given a horizontally expiring edge design of the tub shape 2.

The trough shape 2 sits in the installed state on a support part T, which is adapted to the planform to the trough shape 2, further adapted to the inner free surface spanned by the Randabwinklungen 3.

The carrier part T is divided into two, forming a carrier upper part 6 and a lower carrier part 7. The latter is formed as a shaped body, so produced in the illustrated embodiment based on a particle foam. The carrier base 7 is plate-shaped, with a peripheral edge extension length which corresponds to a multiple of the measured perpendicular thereto thickness of the support base 7.

The carrier base 7 receives a portion of the drain 8, thus centrally an odor trap section 9. This is centrally located at the top, i.e., at the bottom. the carrier upper part 6 facing carrier lower part wide area arranged, wherein a foot-side region of the odor trap portion 9 is embedded in the carrier base 7. The olfactory closure section 9 projects beyond the wide surface of the carrier lower part 7 assigned to the carrier upper part 6, this with a free axial dimension, which corresponds to the distance between the surface of the carrier lower part 7 and underside of the trough-shaped outlet opening 5 in the installed state.

In that regard, alternatively, it may also be provided that only a corresponding recess is provided in the carrier lower part in order to install the outflow, possibly including the odor trap section, on the construction site side.

Within the support member 7 is further connected to the odor trap portion 9, laterally to a narrow edge side of the support base 7 extending and free-flowing in the corresponding Trägeruntererteilfläche drain pipe 10 is integrated. This can be held with a gradient of, for example, 1% in the carrier base 7.

The carrier top 6 is achieved by a foam backing of the tub shape 2. This foam backing or foaming the trough shape 2 by means of a polyurethane foam, wherein the thus produced, directly connected to the tub shape 2 foam body extends in any case preferably up to the plane defined by the free edges of the Kantenabwinklung 3 level E, or even beyond , the latter example. in a measure which corresponds to one-sixth to one-third of the height of the edge bend 3 measured transversely to the plane E.

For foaming or for the formation of the carrier shell 6, a polyurethane foam with a density of 60-100 kg / m ³ is preferably selected.

The foaming is further preferably carried out so that centrally in the axial allocation to the trough-shaped outlet opening 5 a receiving the carrier lower part side odor trap portion 9 serving clearance 11 remains.

For sealing connection of the shower tray structure 1 in preferred floor-level installation to the shower tray structure 1 surrounding floor a sealing tape 12 is further provided. These are first of all the arrangement of four sealing strips assigned to the side edges of the shower tray structure 1, which project beyond the edges for connection to the surrounding floor. In the trough-shaped corner regions, the individual sealing strips 12 are arranged overlapping. It is understood that if necessary, integral Eckausformungen can be provided here.

The sealing tapes 12 are held by means of the end regions facing away from the freely protruding sealing strip sections on the surface of the carrier lower part 7 facing the carrier upper part 6, thus, for example, adhesively bonded. Preferably, they are hereby also at the same time sealed. In the illustrated embodiment, the fixing regions of the sealing strip 12 are embedded in a coating 13 applied on the upper side of the carrier lower part 7. This may be a dispersion seal, for example also a plastic mortar combination.

The sealing strip 12 and the sealing strips extend in the installed state of the shower tray structure 1 in a plane parallel to the E plane defined by the edge bend 3 (the end edge), so on in a plane E ', the separation plane of carrier top 6 and Carrier base 7 corresponds. Alternatively, the sealing strip 12 may also be foamed in the course of the preparation of the carrier base 7 and / or the carrier shell 6 with the inwardly facing band sections, so that the sealing strip 12 is taken accordingly in the carrier base 7, this with free, lateral Abrangen the sealing effect sections.

The sealing tape 12 can continue, as in the embodiment shown in FIG Fig. 4 shown to be a portion of a blanket sealing film 14. This extends, taking into account the contact surface of the support base 7 passing through the odor trap portion 9 over the entire, the carrier top 6 facing surface of the carrier base 7, under edge-free lips of the sealing strip sections. The sealing film 14 is glued in this case preferably the entire surface with the carrier lower part 7.

With respect to the circumferential sealing strip 12, this may in the usual way, as also described, consist of individual strips, which are then arranged overlapping in the corner and also separately glued together in the overlap (so that they are then glued together over the entire width ). But it can also be an integrally formed sealing tape, such as. The described sealing film 14, but also by punching an integral sealing strip from a corresponding wide band. Further, the sealing tape can also be made of individual strips which are glued or welded together in the corner areas, for example along a diagonal.

As far as above and below the sealing composite is addressed with the surrounding floor structure, this of course also includes a sealing composite with upstanding walls. For example, when installing a shower tray assembly 1 in a corner of the room must be made on two sides, the seal with an ascending wall.

As in the in the Figures 1 - 3 illustrated first embodiment, the carrier shell 6 can be done by training or foam backing the tub shape 2 with only a polyurethane foam. Alternatively, it is also possible, only the peripheral, the Randabwinklung 3 associated edge region of the carrier upper part 6 of a polyurethane foam higher density A (density about 60-100 kg / m ³ ) to form. The inner carrier shell region is foamed with a polyurethane foam of lower density B, so for example. With a polyurethane foam having a density of 6-30 kg / m ³ (see Fig. 5 ).

Carrier upper part 6 and lower carrier part 7 are assembled either factory or alternatively only on site, this under full-surface support of the carrier shell 6 on the support base 7. So is first according to the in the Figures 1 - 5 shown embodiments, a bonding, in particular sealing bonding of carrier top 6 and lower carrier part 7 is preferred, wherein the adhesive or parting plane between the two parts in a continuous horizontal plane E 'is provided, in which plane at the same time also the sealing strip 12 extends.

Also, the joining of carrier top 6 and lower carrier part 7 according to the embodiments in the FIGS. 6 and 7 be given in the sense of a mutual engagement of the parts. Thus, in the illustrated embodiment of the Fig. 6 the region of higher density foaming A is provided with a greater height considered perpendicular to the plane E 'than the middle one Carrier top portion, which consists of a foam of lower density B. Thus, facing the lower carrier part 7, in the transition between the central carrier upper part section and the edge region with higher-density foam, there is a circumferential step into which a height-adjusted elevation 17 of the carrier lower part 7, which corresponds to the floor plan of the inner carrier upper part region, engages in order to form a positive connection can still be supported by gluing the parts together. Next alternatively, as in Fig. 7 shown to be provided a pin-shaped connection. Thus projecting perpendicularly from the top of the carrier 6 facing the surface of the carrier lower part 7 projecting pins 18, which are integrally formed with the carrier lower part 7 of a particle foam. These are assigned in a projection on a base carrier upper part side recesses 19. Pin 18 and recesses 19 may be circular in plan. Also, strip-like solutions are possible in this regard.

Another unclaimed embodiment show the Figures 8-10 , Here, the support part T is formed from a, adjustable support feet 20 having support frame 21. In the illustrated embodiment, eight support feet 20 are provided, four each associated with the corners and another four at half the extent of the corner regions connecting frame legs. The latter are formed in the illustrated embodiment as square bars 22. These sit in each end of, bar ends receiving, bottom side provided with the support feet 20 corner connecting parts 23. These are formed as plastic parts, further in the form of plastic injection molded parts.

The half-length of the frame legs arranged support feet 20 are provided with support portions 24 which are traversed by the respective frame legs in the transverse direction. These support sections 24 are preferably formed as plastic parts, further example. Made by plastic injection molding. Support sections 24 and corner connecting parts 23 clamp on the support surface facing away from the storage area of the support part T to a common plane.

The trough mold 2 is provided on the underside with an insert-foam part 25. In the illustrated exemplary embodiment, this is a frame part produced from a polyurethane foam, which is held on the underside of the trough mold 2, assigned to the edge bend 3.

The foam part 25 is in cross-section as shown in FIG Fig. 9 double L-shaped, with L-shaped legs facing in opposite directions. Thus, an inwardly facing first L-leg 26 is positioned to support the lower side of the tub shape 2, between which L-leg 26 and the tub shape 2, a self-adhesive layer 27 is provided.

From the Randabwinklung 3 facing the end of the L-leg 26 is perpendicular in cross section to this aligned down in the direction of the free edge of the Randabwinklung 3 facing away from the L-web 28, which in turn pointing in the other, outward to the tub shape edge L-leg 29 passes.

The L-leg 29 is assigned to the edge bend 3 on the underside, wherein the upwardly facing surface of the L-leg 29 drops in cross-section starting from the edge region inwards. On this surface, the sealing tape 12 is fixed by means of an adhesive layer 30. This is as in the embodiments described above at the edge over to the sealing connection of the shower tray assembly 1 to the surrounding floor area.

On the upper side, the adhesive-applied sealing band section is loaded by an angle-shaped end section of the edge bend 3.

The outer, in particular vertically aligned free surface of the L-leg 29 is aligned in the illustrated embodiment with the vertical surface of the edge bend. 3

The carrier T is supported by means of its height-adjustable support feet 20, further concretely in the illustrated embodiment via the Eckverbindungsteile 23 and support portions 24 on the underside of the L-leg 26 on the insert foam part 25 from, or, this enforcing, directly on the tub shape.

Finally, the show Figures 11-14 a further unclaimed embodiment in which the sealing strip 12 between the trough shape 2 and a here only in dash-dotted line art reproduced schematically carrier T is included such that the sealing tape 12 is disposed on the inside following the trough shape edge contour.
Correspondingly, the sealing strip 12 extends in a cross section through the trough shape 2, starting from the rear surface associated with the trough forming surface 4, enclosing an angle of approximately 90 degrees, along the edge bend 3 on the inside, then again freely outwardly encircling an angle of approximately 90 degrees (see. Fig. 12 ).
In the corner regions of the trough mold 2, the sealing tape 12 is formed as a preformed, the corner-yielding part 31. This is formed in the illustrated embodiment as a deep-drawn part corresponding to the inside Eckausformung the trough shape 2, correspondingly has two, in plan view an angle of 90 degrees enclosing side wall portions 33 and a ceiling portion 34 connecting them. Edge of the ceiling section, along a protruding into the sealing band connection collar 35, the corner member 31 is associated with the freely projecting sealing band 12. This is with the facing, the Randabwinklung 3 of the trough shape 2 cross and extending in the sealing plane connecting collar 35, for example. Welded.

Each corner of the tub shape 2 is assigned a corner part 31. The sealing strip 12 may be formed in this embodiment from a suitably punched foil or the like with a shape dominating the trough 2, wherein the free punching is further selected so that 31 sealing tape sections 32 remain in the area between two corner parts, the Tannenforminnenseitig a sealing connection between two Corner parts 31 produce.

Alternatively, a circumferential frame may be formed in accordance with the previously described corner parts 31, for example as a deep-drawn part, alternatively also as a molded part, to which the sealing strip 12 only adjoins peripherally in one plane.

With regard to all described embodiments and objects of the application can also be provided that the sealing strip (in cross section) is led out laterally at an acute angle to the horizontal from the tub structure. An angle of up to +/- 60 °, for example, is possible here. For example, an angle of 45 ° downward or of a horizontal is preferred. Regardless, however, all angles in the stated range of up to +/- 60 ° are included in the disclosure, particularly in 1 degree increments.
