Description

Combination of a hard foam carrier body and a plate body, in particular as part of a shower system

The invention relates to an intended for fitting in a floor structure combination of a rigid foam carrier body and arranged above it, preferably rigidly connected to the rigid foam body plate body, in particular as part of a shower system, wherein the plate body is a sanitary plate such as a natural stone, plastic or mineral material plate is, and wherein further circumferentially parallel to the Plattenkör- per a sealing tape is arranged, for sealing association with the surrounding floor structure in the installed state.

Combinations of the type in question are known, for example in the form of floor-level shower trays. In order to securely seal the transition from such a combination placed on a raw floor to the surrounding floor structure, such combinations are already provided at the factory with a sealing tape. In this regard, solutions are known in which such a sealing tape is arranged resting on the support body immediately below the plate body. When assembling the combination u.U. Mistakes result that lead to leaks.

Especially in the case of thinner sanitary surfaces, it is necessary, in the installed state, to lay the sealing tape facing downwards, with a corresponding bend. This leads in particular in corner areas to difficulties.

Based on the above-described prior art, the invention has the object to provide an advantageous arrangement and integration of the sealing tape in the combination in view of the combinations in question.

This object is achieved first and foremost in the subject matter of claim 1, wherein it is pointed out that the upper side of a Under the plate body arranged fixed part covered sealing tape is provided by the circumferential, usually vertical face of the rigid foam body expansively. The sealing tape can be fixed solely to the rigid foam body. On the one hand, this opens up the possibility of finishing the hard foam body with sealing tape at the factory without a carrier part already being applied. On the other hand, a combination of support member and plate body can be provided at the factory and the sealing tape can be safely introduced subsequently. If necessary, it can therefore only be introduced locally if required, ie on the construction site before placing the combination on the unfinished floor. The solid part may be an integral part of the rigid foam body. But it may also be a separate part, which is placed on the upper side of the sealing part. The fact that the sealing strip is embedded in the circumferential end face of the rigid foam carrier body, it runs at a significant distance to the separation plane between the carrier body and the plate body. The distance can in particular in the range of a finger thickness, so for example 5 mm or more, in particular 10, 15 or 30 mm to move.

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 in a room corner, the seal must be made on two sides with an ascending wall.

The subjects of the further claims are explained below in relation to the subject matter of claim 1, but may also be significant in their independent formulation.

Thus, it is preferably provided that the sealing strip is embedded in the rigid foam body. This, for example, by a slot-like recess, circumferentially in the front. Further, it is preferably provided that the sealing tape in the Hard foam body is adhesive. As far as a receiving slot is provided, this is preferably prepared in the factory in the rigid foam body. Alternatively, it is also possible to form this slot only on site immediately before the onset of the sealing strip. The slot cross-section is preferably adapted to the sealing strip cross-section, wherein further a final determination of the sealing strip is achieved by introducing an adhesive into the slot. Further alternatively, in the rigid foam body, a circumferential, the end face of the rigid foam body opening groove may be formed, in which the sealing tape is adhesive and / or clamped. This circumferential groove is further enlarged in cross section relative to the sealing band. In a proposed clamp holder of the sealing strip in the groove latter is formed correspondingly large in cross-section. There is also the possibility that the hard foam body is formed in two parts in the edge region and that the sealing tape between the parts is taken. Accordingly, the vertical circumferential end face of the rigid foam body is not slotted or grooved for receiving the sealing strip, but rather a circumferential Eckausnehmung, a grading, provided, in which recess the sealing tape can be inserted and which recess thereafter by a corresponding fitting piece, the fixed part, again verschlos - sen. Thus, a separate edge part may be provided on the hard foam body, between which edge part and the extent graduated edge of the remaining rigid foam body, the sealing tape is enclosed. The edge part can in this case be designed in several parts, for example in four parts. There is also the possibility of a frame-like, corresponding circumferentially integral edge part. In such a solution, the sealing tape is already used at the factory and set to thereafter first set up the edge part and finally to cover the already provided with the sealing strip rigid foam body with the plate body. In this case, the edge part can be adhesively bonded to the remaining edge of the hard foam body, so for example over the entire surface. In this regard, it is preferred to choose a bond which is an insoluble compound between edge part and hard foam body provides. The edge part may be the same as the rigid foam body also formed as a rigid foam part, so on in the simplest way by free cutting of the edge part of the foam body block. Alternatively, the edge part may also be formed as a plastic part, for example injection-molded plastic part, such as solid plastic part, according to which an edge reinforcement of the rigid foam body is reached. There is also the possibility that the edge part is formed as a mineral material part. Also, the edge part may be a metal part. It is further preferred that the edge part terminates flush with the rigid foam part on the upper side, insofar as part of the rigid foam forms a flat support surface for the plate body. If the sealing tape is inserted into a circumferential groove and clamped there, this clamping body can be designed as a cross-sectionally clip-like profile. The latter can also be a plastic profile or a metal profile. This clip-like profile is determined together with the sealing tape in the groove of the rigid foam body by gluing or by embedding in a glue bed. Alternatively, the clamping body may also be a plastic profile, so on, for example, with wedge-shaped or rectangular cross-section. Also, a round or oval cross-section of the clamping body is conceivable. Also, the clamping body may be a rigid foam profile. Next alternatively, it is also possible to manufacture the clamping body of a mineral material or natural stone profile. These clamp bodies are glued in the groove under the clamp of the sealing tape. It also proves to be advantageous if the sealing tape in the receiving groove and / or the receiving slot by means of a potting compound, such as a concrete-like potting compound, arrested. Such a potting compound initially serves to seal the rigid foam surface. For this purpose, the surface is covered with the potting compound, which then also enters the receiving groove or in the receiving slot. Immediately thereafter, the sealing tape is inserted into the slot or into the groove. The curing potting sets according to the sealing tape to the rigid foam body. In a further embodiment, it is also preferable to provide the sealing tape in the supporting body resting on a permanently elastic adhesive layer. In principle, it can also be a butyl layer. It is also preferred that the sealing strip is covered as an alternative or in addition by such a permanently elastic adhesive layer. Insofar as the aforementioned permanently elastic adhesive layer is provided on the upper and lower sides, it is further preferred that they lie directly adjacent to one another on the inside of the carrier body, thus forming a kind of pocket in cross-section, opened to the outside, in which the sealing tape rests. This pocket-like embedding of a sealing tape between two permanently elastic adhesive layers, in particular butyl-based adhesive layers, also has independent significance, that is independent of the fit in a combination of rigid foam support body and plate body of a shower system described here. For example, it can also be used for conventional bathtubs or for other sealing purposes.

Instead of an upper and lower-side permanently elastic adhesive layer may in principle be provided for the aforementioned formation of pockets, an arrangement in which the underside and / or top side a double-sided adhesive tape is arranged. Depending on the quality, however, problems with respect to the sealing may arise here, so that, if necessary, an additional sealing means, for example arranged outwardly to the adhesive tape, must be provided. On the upper side and / or underside, adhesive beads, for example of MS polymer, may also be provided with regard to the bordering of the sealing strip in the covering area to the support body.

It is also advantageous to provide the arrangement of said adhesive layers and / or of the fixed part in such a way that in the horizontal direction a certain distance, ie a circumferential groove, rises to the inner region of the support body, which rises in steps over the sealing strip. remains. These rings ne is then covered in the assembled state only by the sanitary plate.

The support body, in particular if it consists of particle foam, preferably has a density in the range of about 40 to 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 support body is reached. In particular, in support bodies of particle foam such high density, then can be dispensed with any other bonding layer between the support body and the other elements.

The adhesive layers, as also explained with reference to the following embodiments, are then directly on the support body.

The invention with reference to the accompanying drawings, which only illustrates several embodiments, explained in more detail. It shows.

Fig. 10 is a plan view of a prefabricated, circumferential sealing strip.

1, a combination 1 consisting of a rigid foam carrier body 2 and a plate body 3 arranged above it and integral with the rigid foam carrier body 2 is shown and described. The rigid foam body preferably consists of a particle foam , such as EPP or EPS. In addition, it may also consist of an extruded foam such as XPS or of a Polyuhrethan rigid foam. The plate body 3 serves as a sanitary plate for a shower system and consists for example of a solid surface panel.

In the middle of the combination 1, a sequence 4 is provided.

The combination 1 is used for arrangement on a raw floor 5. In, as shown schematically in Fig. 1 installation state, the combination 1 is surrounded of a floor structure 6. In the exemplary embodiment shown, it is composed of a screed layer 7 applied to the unfinished floor 5 and a tile layer 9 arranged above it and arranged over an adhesive layer 8.

For sealing composite of the combination 1 to the surrounding floor structure 6, the combination 1 comprises a circumferential sealing strip 10. This is initially provided within the rigid foam body 2, of the circumferential vertical end face 11 of the same expansively embedded in this, this with a distance to the foam body surface. Accordingly lippt from each end face 11 of the rigid foam body 2, starting from a sealing strip 10 free from, for sealing interaction with the floor structure 6, (or as further mentioned above, optionally an upstanding wall) in which, for example, the sealing tape 10 with the free auslippenden area between screed layer 7 and tile layer 9 is inserted and fixed. For this purpose, the sealing tape, in which the tile or the screed assigned area previously be coated above and / or underside with a corresponding adhesive.

With regard to the circumferential sealing strip, this can initially consist of individual strips in the usual way, which are then arranged overlapping in the corner regions and are also glued separately in the overlap (so that they are then glued together over the entire width). However, it may also be an integrally formed sealing strip 10 'measured by the figure. In this case, this sealing strip can be made from a correspondingly wide band as a whole by punching. It can also be made of individual strips, which are glued or welded together in the corner areas, for example along a diagonal.

Further, the sealing tape 10 or 10 '(this is therefore possible for both embodiments addressed) in particular in the outer edge region, given but if also be provided over the entire width, with holes in which the adhesive or the sealant is then arranged cross and at the same time provides an anchorage.

FIGS. 2 to 8 show various exemplary embodiments for the possible fixing of the sealing strip 10 in the rigid foam body 2.

Thus, a solution is initially proposed as shown in Fig. 2, in which circumferentially in the end face 11, a receiving slot 12 is worked out. This extends in cross section parallel to the bottom surface 13 of the rigid foam body 2. In this receiving slot 12, an edge portion of the sealing strip 10 is inserted and by means of a sealing adhesive 14, which may correspond to the sealing adhesive 15 between hard foam body 2 and plate body 3 set. The integrated portion of the hard foam body 2, which projects beyond the sealing tape 10 on the upper side and forms part of the end face of the support body, represents the solid part covering the sealing tape.

The insertion and setting of the sealing strip 10 by means of the sealing adhesive 14 can also be done only on site, immediately before placing the combination 1 on the unfinished floor. The receiving slot 12 is already provided at the factory or, alternatively, can only be formed on site by means of a corresponding cutting tool.

A similar solution is shown in FIGS. 3 and 4. Here, however, the receiving slot is widened to a circumferential groove 16, which opens in each case towards the end faces 11, which is selected to be many times greater, in particular, than the thickness measured in the same direction of the sealing strip 10. Does the receiving slot 12 according to the embodiment in Fig. 2 has a height which corresponds approximately to two to twenty times the sealing strip thickness, the corresponding height of the groove according to the embodiments chosen in the illustrations of Figs. 3 and 4 about 50 to 100 times greater than the sealing tape thickness. Accordingly, the determination of the sealing tape in the groove 16 is not only by gluing. Rather, a clamping body 17 is provided. This is approximately cross-section adapted to the groove 16 and extends over the entire length of the groove 16. Alternatively, viewed over the length of the groove 16 and isolated clamping body 17 may be provided.

By means of the clamping body 17, the sealing tape 10 is fixed in the groove 16, which definition is reinforced by the introduced sealing adhesive 14.

The sealing strip 10 can, as shown in Fig. 3, only one side acted upon by the clamping body 17 against the associated Nutwandung be determined by pressing. As an alternative, however, the end section of the sealing strip 10 to be fixed can also be inserted into the groove 16 in the clamping body 17 and fixed accordingly.

With regard to the formation of the clamping body 17, various embodiments arise. Thus, the clamping body 17 can be formed as shown in FIG. 3 as a cross-sectionally approximately rectangular plastic profile 18. With a similar cross section, the clamping body can also be present as rigid foam strip. Further alternative embodiments provide clamping body 17 of mineral material or natural stone.

As can be seen from the illustration in FIG. 4, in an alternative embodiment, a clamp-like clamping profile 19 is provided for forming the clamping body 17. This clamping profile 19 is shown in Fig. 5 in a single representation. This may be a plastic part or a metal part, which is omega-shaped in cross-section with two resiliently adjusted holding portions 20 which act on each other and hold between the associated portion of the sealing strip 10 by clamping. The Clamping profile 19 itself is fixed in the groove 16 by means of the introduced sealing adhesive 14. As indicated schematically in FIG. 5, isolated clamping profile sections may be provided over the length of a groove 16.

Another, only factory-produced alternative embodiment, Figs. 6 and 7. Here, the edge region of the rigid foam support body 2 is formed in two parts, wherein the sealing tape 10 is taken between these parts. Thus, the hard foam carrier body 2 circumferentially in the upper, d. H. the area to be assigned later to the plate body 3 a circumferential corner recess 21 on. This is shaped as a step. In this both the associated end face 11 as well as the top of the rigid foam body 2 open Eckausnehmung 21 a recess that essentially filling the edge part 22 is inserted. Corresponding to the four peripheral edges of the rigid foam body 2, four edge portions 22 may also be provided. Alternatively, the edge part 22 can also be present in one piece, like a frame.

The sealing strip 10 is clamped with the rigid foam body 2 associated end between the edge portion 22 and the Eckausnehmungsboden of the rigid foam body 2, wherein further the edge portion 22 is bonded to the remaining edge of the Eckausnehmung 21. In addition, the clamped sealing band section can also be glued.

As shown in Fig. 6, the edge portion 22 may be equal to the support body 2 made of a rigid foam. Alternatively, the edge portion 22, as shown in Fig. 7, also be a solid part, such as a solid plastic part or a mineral material part.

The edge portion 22 is further dimensioned and positioned so that the same with the hard foam part 2 on the upper side, ie facing the plate body 3 equal-level closes, according to which results in a flat surface for supporting the plate body 3. The illustration in FIG. 8 relates to an embodiment in which the hard foam body 2 is coated with a sealing potting compound 23 at least in the area of the surface and the end faces 11. The end faces 11 are equal to the first embodiment provided with receiving slots 12 which are filled in the course of the coating of the rigid foam body 2 by means of the potting compound 23 thereof. The sealing tape 10 is then inserted into the still moist mass. After curing of the potting compound 23, the sealing tape 10 is set accordingly safe.

In the embodiment of FIG. 9, first of all the plate body 3 has on the edge side an angled downward bend 24. Such an angling 24 can also be provided in the plate bodies of the embodiments described above, wherein an outwardly facing edge surface of the angled portion is preferably aligned with the end face 11 of the carrier body 2.

Furthermore, in the exemplary embodiment of FIG. 9, it can be seen that the sealing strip 10 rests on a step surface 25, specifically in the exemplary embodiment by means of a permanently elastic adhesive layer 26. This adhesive layer 26 can be formed in particular based on butyl. It is not only an adhesive layer but also a sealing layer. The plastoelastic behavior of such an adhesive layer, ie in particular a butyl layer, leads to an intimate penetration of the adhesive into the structures of the sealing strip 10. Since this is preferably textile-based, it has a corresponding surface structure.

The adhesive layer 26 is particularly preferably formed on a butyl rubber base. A single adhesive layer 26 may have a thickness between 1 mm and 2.5 mm, preferably 1.5 mm to 2 mm. It is further preferred, and realized in the embodiment of Figure 9, that the adhesive layer 26 consists of an adhesive tape, which as such, without that is to be applied from a tube or the like adhesive in individual strands, laid.

A further adhesive layer 27, also embodied here preferably as an adhesive tape as described above, is arranged on the upper side of the sealing strip 10. In this case, in the cross-sectional representation of a pocket-like closed envelope of the sealing strip 10, in the overlap region to the support body 2. The area a can be an extension of, for example have one or two or more finger widths.

Further inward to the area a is followed by an open area b, which remains as an upwardly open channel. On the other hand, what is not shown in detail here, the arrangement may also be provided so that no free area b results or that this area b is filled with adhesive, as otherwise also used for bonding between the plate body 3 and the support body 2 ,

Above the sealing strip 10, in the embodiment of Figure 9 placed on and connected to the adhesive layer 27, a rim portion 22 is arranged. The edge portion 22 has an extension in the illustrated cross section, which is composed of the extent of the region A and the overlap region between the adhesive layers 27 and / or 26 to the sealing strip 10. As can be seen, it is a flat rectangular fixed part.

It can be a foam part, but it is preferably a solid plastic part, for example a polystyrene part. It can be an extrusion or injection-molded plastic part. It can also be a blackboard a cut or punched out part. However, solid plastic part should not mean that the part can not be chambered, for example.

Above the edge part 22, a preferably in the form of individual adhesive beads applied elastic (permanently elastic) adhesive in the form of an adhesive layer 28 is provided. It is, at least in principle, to the same adhesive to the same adhesive, which also provides the remainder of the arrest between the plate body 3 and the support body 2. In particular, an adhesive on an MS polymer merbasis. It is an adhesive based on modified silane.

The step surface 25, which extends horizontally in the cross section, can preferably also be designed with a slight downward gradient toward the interior of the support body 2. This gradient preferably moves in the range of a few degrees, that is about 1 to 4 degrees. In the same way, the support body in the interior, ie outside the edge Eckausnehmung, have a slight downward gradient towards the inside.

All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
