Description

The present invention relates to a sanitary tub arrangement with a sanitary tub from a tub body, which is inserted with a downwardly angled from an upper edge of the tub in the direction of a side edge of the tub body in an upwardly open channel, in which a sanitary tub against the gutter sealing sealing material located. The invention also provides a method for installing a sanitary tub in a receiving space. The invention relates in particular to sanitary tubs with a tub body made of a layer material.

For sanitary tubs such as shower trays, bathtubs and wash basins, a good seal against the surrounding building structure must be ensured. It must be avoided that splash water or overflowing water in the area of the sanitary tub penetrates into the building structure and thus can lead to considerable damage, which can be determined in part only with a greater delay.

In order to achieve a good and reliable seal, sealing tapes are used in practice, which are attached to the sanitary tub and on the other hand, an adjacent wall or floor surface. Corresponding sealing tapes are made DE 299 05 152 U1 . DE 295 21 668 U1 . DE 100 31 214 A1 . DE 10 2014 102 045 A1 and DE 20 2006 010 243 U1 known, according to the DE 20 2006 010 243 U1 the sealing tape together with a support frame forms a channel in which a sealing strip rests against a lower edge of the sanitary tub.

A sanitary tub arrangement with the features of the preamble of claim 1 is known from GB 2 323 278 A known, wherein the sealing material is first inserted into the upwardly open channel before a lower edge of the sanitary tub is placed on the sealing material.

In the long-term use of a sanitary tub, it must be taken into account that certain deformations, such as setting behavior, of a building construction can not be excluded. There is then the danger that the sanitary tub is separated from the sealing material by appropriate movements, which can then arise corresponding leaks. In addition, the sealing material must be introduced with a precisely defined amount in order to achieve a reliable seal of the sanitary tub in the associated channel.

Against this background, the present invention has the object, especially in a long-term use of the sanitary tub assembly to further increase the safety of the seal and to allow easy assembly during assembly.

The object of the invention and solution of the problem are a sanitary tub arrangement according to claim 1 and method for installing a sanitary tub according to claim 14 and 15.

Based on a sanitary tub arrangement with the feature described above, the invention provides that in the channel on at least part of a circumference of the sanitary tub, the side edge of the tub body is completely embedded in the sealing material.

Preferably, the tub body is formed from a layer material, wherein the side edge of the layer material is completely embedded in the sealing material.

The present sanitary tub arrangement is then initially of a configuration in which below the laterally angled down portion of the layer material, a channel is arranged, which receives the sanitary tub - at least on a part of its circumference -.

The sanitary tub is then inserted into this channel and sealed against this channel, which is independent of an additional seal by a sealing tape or the like appropriate. Such a sealing tape can for example also be embedded in the sealing material in order to achieve a reliable and permanent seal.

According to the invention the side edge of the tub body or of the layer material is completely embedded in the sealing material, in particular cast, so that the sealing material not only on an end face of the side edge, but also on both sides laterally to such an end face and in particular in an upper region of the Surrounding sealing material. Usually, the layer material, starting from the side edge, is embedded in the sealing material over a length of at least 5 mm, preferably at least 10 mm or more.

Even with a movement of the channel relative to the sanitary tub, a secure seal can be ensured. In particular, the sealing material can also reduce the risk of such deformation per se depending on the strength. Since the sealing material also extends above the side edge, the sanitary tub can not be easily raised relative to the channel. Even with a lifting of the sanitary tub with respect to the channel, the sealing material is retained because it engages around the side edge on three sides.

In order to achieve the described arrangement, a sealing material must be used in the context of the invention, which is sufficiently fluid to embed the side edge during assembly can.

According to the described embodiment of the invention, the sanitary tub is formed of a layer material. As a layer material in the context of the invention in particular to a sanitary tub formed plates from Sanitäracryl and steel enamel understood. The layer material usually has a layer thickness of less than 10 mm, in particular less than 5 mm. The typical thickness of steel enamel is usually between 1.5 mm and 4 mm.

According to a preferred embodiment of the invention adjoins the downwardly angled portion of the layer material at a lower edge with the side edge. In the context of such a configuration is preferably provided that not only the side edge itself, but also the lower edge is completely embedded in the sealing material. The sanitary tub is then reliably held securely over the entire length of the lower edge and sealed. The flowable and preferably pourable sealing material is in the described embodiment during assembly in a position not only to enclose the side edge, but also to cover the top of the lower edge.

Usually, the layer material is wetted by the sealing material, whereby an intimate adhesive bond can also arise.

For the design of the sealing material, various possibilities arise within the scope of the invention. First, the sealing material must be durable be waterproof and should also have as much as possible a certain resistance to various chemicals such as detergents.

On this basis, sealing materials come into consideration, which are cured in the assembled state to a solid or which are permanently liquid, in particular viscous.

For example, the sealing material may be formed on a polymer basis, such a sealing material preferably having permanently elastic properties in order to be able to absorb without deformation of the sanitary tub and / or an adjacent building structure without breaking. Suitable sealing materials are, for example, hardening resins, silicones or the like. Such materials may be chemically cured by a mixture of various components (two-component resin) or else alone, for example by contact with air, although, as described above, even after curing, there is some elasticity.

Various chemically curing adhesives are suitable in the context of the invention as a sealing material, initially a low viscosity is advantageous during assembly, so that the sealing material can initially distribute evenly.

In addition to chemically curing materials, physically hardening sealing materials are also possible within the scope of the invention. A physical hardening is present, for example, when the sealing material solidifies during assembly by cooling or evaporation of a solvent (eg alcohol or water). So it is conceivable, for example, to liquefy a plastic by heating and then bring in the manner described in the groove, which then embedded in the liquid state, the side edge becomes. For example, viscous oils, bitumen or a non-water-soluble gel may be considered for this purpose.

In the case of a non-water-soluble and permanently viscous sealing material, the dynamic viscosity η at 20 ° C. is preferably between 1 and 1000 Pa · s (pascal second), in particular between 10 and 100 Pa · s.

When certain deformations occur in the long-term use of the sanitary tub assembly, stresses in a permanently viscous sealing material can be prevented by flow of this sealing material.

In order to be able to move to a sufficient extent in the built-in sanitary tub arrangement, the sealing material according to a preferred embodiment of the invention is relatively soft. Thus, the Shore hardness determined according to DIN EN ISO 868: 2003 is preferably between 20 and 85 Shore A, particularly preferably between 30 and 60 Shore A, the Shore hardness measurement method being based on the limited retention time of 15 seconds when determining the penetration depth Not only for solids, but also for highly viscous liquids can be used. In any case, the transition between a highly viscous liquid and a solid is not unique and is not relevant to the invention.

According to the invention, the downwardly angled section is arranged in a groove, which can be easily filled during assembly with the initially flowable sealing material. The channel may for example be formed from a plastic, a composite profile or a metal profile, wherein such a profile may also be part of a sanitary tub supporting support structure. Suitable profiles are for example from the DE 10 2009 037 904 B3 known, wherein arranged on such profiles and feet of the support structure can be. As a composite material, for example, mixtures of reinforcing materials with thermoplastic or thermosetting plastics (resins) into consideration.

However, the present invention is not limited to rigid gutters made of a plastic or metal profile. Alternatively, a channel can also be formed by a flexible, watertight material strip, for example a sealing strip known from the prior art. A sealing band can be fastened to an underside of the layer material in the region of the upper edge of the tub and then guided outwards around the downwardly angled section of the layer material, whereby the channel shape described forms. By at least partially pouring this channel through the sealing material with the inclusion of the free side edge a particularly reliable and durable sealing structure is produced. In particular, the initially flowable in the processing and then preferably at least still permanently elastic sealing material can also contribute to improved sound and heat insulation of the sanitary tub.

The channel described can in principle also be provided in a tray carrier made of foam (for example Styropor®), hard foam, wood or in a comparable load-bearing construction. Furthermore, it is also possible to use a kind of film instead of a waterproof material strip, which either runs completely below the sanitary pan or is arranged as a kind of frame below the ball edge.

Finally, a part of the channel of a rigid profile and another part of the channel can be formed from a flexible, waterproof material strip. In particular, it may be appropriate to use a sealing tape with pour in the sealing material, whereby the sealing strip is fixed particularly reliably and firmly.

Regardless of the specific design of the channel, it may be sealed in the region of the upper edge of the tub against an underside of the layer material. As a result, it can be prevented during assembly that the sealing material overflows inwards over the channel. Depending on the specific requirements with regard to the installation situation, however, an internal seal can alternatively be dispensed with. Thus, for example, installation situations are conceivable in which an overflow can be tolerated inside, while an overflow of the sealing material in the outer region of the channel is disadvantageous, because then the sealing material may need to be removed, for example, to apply a silicone joint can. If, in this context, the sealing material from the channel can overflow inwards, a corresponding filling level of the sealing material in the channel can not be exceeded.

In order to reduce the amount of sealing material used, parts of the channel can be designed with fillers such as foam or the like, but it should still be ensured that the free side edge of the layer material is embedded in the sealing material, which usually results in an adhesive connection.

The invention also provides a method for installing a sanitary tub in a receiving space of a building construction having at least one wall or floor surface, the sanitary tub being formed from a layer material, in particular sanitary acrylic or steel enamel, and the layer material starting from an upper tub rim Direction of a side edge of the layer material angled downwards Section, wherein an upwardly open channel is disposed on at least one edge of the receiving space, wherein a sealing material is introduced into the channel and wherein the sanitary tub is inserted with the downwardly angled portion in the channel and connected to the sealing material. On this basis, the invention provides that a flowable sealing material is introduced into the channel and the sanitary tub is inserted with the downwardly angled portion in the channel such that at least part of a circumference of the sanitary tub, the flowable sealing material flows around the side edge and thereby fully embeds. The flowable sealing material may be such that it also has a constant viscosity at a constant ambient temperature. Then, however, in terms of fluidity, it is necessary to select a material which, on the one hand, is thin enough to flow around the side edge and, on the other hand, can not be displaced or dissolved by water.

According to a variant that can be combined with the described method features, but represents an independent patentable teaching variant, the present invention also relates to a method for installing a sanitary tub in a receiving space of at least one wall or floor surface having building construction, the sanitary tub with a starting from an upper tub edge down angled portion is inserted into an upwardly open, at at least arranged an edge of the receptacle groove, and wherein a sealing material is introduced into the channel and connected to the sanitary tub, wherein according to the invention provided that the sealing material η having a first dynamic viscosity ₁ less than 100 Pa · s, preferably s is introduced into the channel less than 10 Pa · wherein subsequently the sealing material cures chemically and / or physically and then either as a viscous liquid, a second dynamic viscosity η ₂ which is at least ten times the first dynamic viscosity η ₁ or forms a solid, which preferably has elastic properties. Since the sealing material cures in the context of the described variant, this may first be thin in its processing, resulting in a particularly easy handling. Due to the available materials, the first dynamic viscosity η _{1 will be} greater than 0.001 Pa · s (1 mPa · s). Preferably, the viscosity is greater than 10 mPa · s.

In both described, combinable variants of the method, the sealing material can be introduced before or after the correct arrangement of the sanitary tub in the receiving space in the gutter.

If the sanitary tub is first placed in the receiving space in the correct position and inserted with the downwardly angled portion in the gutter before the sealing material is introduced into the gutter, the sanitary tub can be first accurately positioned and aligned without hurry. The sealing material may then be poured through a side gap between the sanitary tub and the adjacent wall or floor surface.

With a low viscosity of the sealing material during its processing, then there is also the advantage that the sealing material not only flow around the side edge, but can also be easily distributed along the extent of the channel.

If, however, the sealing material is first introduced into the channel before the sanitary tub is arranged in the correct position and inserted into the channel, there is the advantage that the channel is easily accessible from above when the sealing material is introduced. For a hardening sealing material, however, a limited processing time has to be considered.

If a permanently viscous sealing material is used, finally, there is also the advantage that the sanitary tub can be disassembled relatively easily despite a secure seal.

The height of the sealing material in the channel may for example be between 6 mm and 60 mm, preferably between 10 mm and 50 mm. If a thin-bodied sealing material is used at least during processing, an at least approximately equal height of the sealing material results at the angled section of the layer material below the upper edge of the tub on the one hand and on an outer side on the other hand, if no part of the channel is filled by an additional filling material.

If, within the scope of the invention, a sealing material which hardens to form a solid body is used and the channel is formed by a rigid plastic or metal profile, the weight of the sanitary tray and the liquid accumulated therein, and possibly also the weight of a user, can be partially or completely across the channel and the sealing material to be supported, so that then in the context of such a configuration, the support structure can be simplified.

The Fig. 1 to 8 show in a section an outer region of a sanitary tub with an adjoining horizontal bottom surface.

The Fig. 1 shows in a section of a sanitary tub arrangement with a sanitary tub 1 of a layer material, in particular steel enamel, which starting, with one of an upper tub edge 2 in the direction of a side edge 3 of the layer material a downwardly angled portion 4 has. The downwardly angled section 4 is inserted into an upwardly open channel 5.

In the channel 5 there is a flowable at least during its processing and assembly of the sanitary tub 1 sealing material 6, which fully embeds the side edge 3 of the layer material. Since the sealing material 6 is thin at least during the arrangement of the sanitary tub 1, it extends to the downwardly unwound section 4 below the upper edge of the tub 2 on the one hand and on the outside of the sanitary tub 1 on the other hand over the same height or approximately the same height.

In the sealing material 6 not only the side edge 3, but also a sealing tape 7 is embedded, which ensures a seal of the sanitary tub 1 against an adjacent bottom surface 8, which is covered in the illustrated embodiment by a cover material 9, such as tiles.

In the illustrated embodiment, the channel 5 is formed by a plastic or metal profile 10, which is also part of a sanitary tub 1 supporting support structure. For example, in an inwardly directed C-shaped groove 11 according to the DE 10 2009 037 094 B3 Feet are attached.

In the illustrated embodiment, the sanitary tub 1 is supported via a rubber profile 12 on a web of the plastic or metal profile 10. If the web of the plastic or metal profile 10 and the rubber profile 12 extend around the entire circumference of the sanitary tub 1, thereby the upwardly open channel 5 is sealed inwards. This also excludes that the channel 5 can overflow inwards if too much Sealant 6 is introduced. Alternatively, it may be provided that at least the rubber profile 12 is interrupted in sections or also has grooves on its upper side in order to avoid a seal. In such a case, excess sealing material 6 can then run inwards under the sanitary tub 1, which can be harmless per mounting situation. At the same time, however, it can be ensured that the sealing material 6 can not exceed a filling height in the channel 5 predetermined by the overflow height.

Already from the Fig. 1 It can be seen that the sealing material 6 can be cast either before inserting the sanitary tub 1 into the channel 5 or subsequently through a lateral gap 13.

In the exemplary embodiments, a lower edge 14 with the side edge 3 at its end adjoins the downwardly angled section 4 of the layer material. Also, the entire lower edge 14 is embedded in the sealing material 6, so that there is a particularly reliable and durable seal. Even if the sanitary tub 1 is raised to a certain extent relative to the channel 5, the seal is maintained by the sealing material 6, especially if this is permanently elastic or liquid or viscous even in the illustrated assembled state.

Starting from the basic structure according to the Fig. 1 show the Fig. 2 to 8 different variations.

According to the Fig. 2 the sealing tape 7 is attached to the sanitary tub 1. By way of example, according to the Fig. 2 the attachment of the sealing strip 7 at the downwardly angled section 4, wherein the sealing strip 7 may be attached to another location of the sanitary tub 1. With regard to the Fig. 2 For example, the sealing tape 7 can first be fastened to the sanitary tub 1 before the sanitary tub 1 is then positioned in the channel 5 in the correct position. During assembly, the sealing material 6 may already be in the channel 5. Alternatively, during assembly, the sealing strip 7 can also be folded up first, in order then to be able to subsequently fill the sealing material 6 through the lateral gap 13 into the channel 5.

According to the Fig. 3 is provided in an otherwise comparable structure that the gutter 5 forming plastic or metal profile 10 is not part of a support structure, but is laterally attached to the bottom surface 8. As already indicated above, the channel 5 can also be formed by a material other than a plastic or metal profile 10. For profiles other materials such as composites, wood, foam or the like come into consideration. The channel can also be incorporated into a larger load-bearing structure, in which case the aforementioned materials may also be considered. The described embodiment results in an improved decoupling of the bottom surface 8 of the sanitary tub 1, resulting in a better sound insulation and horizontal displacements between the sanitary tub 1 and the bottom surface 8 can be more easily compensated.

In the embodiment according to the Fig. 4 it is shown that the channel 5 can also be formed by a flexible, waterproof material strip, for example the sealing tape 7 described above. The sealing strip 7 is to the side of a plastic or metal profile 10 'connected, which compared to the plastic or metal profile 10 of Fig. 1 has a simplified structure, so that the total manufacturing costs can be reduced. For this purpose, an elastic filling material 15 in the form of a foam strip is also partially arranged in the cross section of the channel 5. Of the Foam strips can be provided in the circumferential direction continuously or only in sections.

The Fig. 5 shows as a further variant that the channel 5 can also be formed from the combination of a plastic or metal profile 10 "and a sealing strip 7. According to the in Fig. 4 illustrated embodiment, filling material 15 is disposed on the inside of the sanitary tub 1 below the upper edge of the tub 2.

The Fig. 6 shows a further variant in which the channel 5 is formed by a sealing strip 7, wherein the sanitary tub 1 is held by a subsequent to the sealing strip 7 Schamstoffträger 16.

According to the Fig. 7 a foam carrier 16 'is provided, which also extends beyond the outer edge of the sanitary tub 1 addition, so that then the channel 5 is formed as an overhead groove in the foam carrier 16'. Even with such a configuration, as described above, a sealing strip 7 can be used. In the case of a foam carrier 16 'passing through under the edge of the sanitary tub 1, the sealing tape 7 can optionally also be omitted if the foam 16' itself is watertight, for example has a waterproof surface coating or sealing.

The Fig. 8 shows, finally, that the channel 5 can also be formed by a first largely free-hanging sealing strip 7, in which case the sanitary tub 1 outside its outer edge can be received by a support structure, not shown. Furthermore, in the Fig. 8 illustrated that the sealing strip 7 may be mounted in the region of the upper edge of the tub at the bottom of the sanitary tub 1. Such an attachment is also in the other embodiments, for example in the embodiments according to the Fig. 4 and the Fig. 6 possible.

In the embodiments, a sealing tape 7 is described which extends at the edge of the sanitary tub. In the context of the invention, in principle, a continuous sealing strip can be used around the circumference. The channel can also be formed by pieces of the sealing strip 7. In particular, special prefabricated corner elements may be provided at corners of the sanitary tub 1, so that a sealing structure is formed around the entire circumference.
