Abstract

The interface between a bathtub and a tiled bathroom wall is closed by a water impermeable sealing strip (42) whose lower face is bonded to the bathtub rim and upper face is bonded to the wall. The sealing strip further has a capillary stop strip.

Description

The invention relates to the connection of a sanitary installation object such as in particular a tub or a basin to a wall and a method for producing such a connection.

Sanitary installation objects such as washbasins, shower trays or bathtubs are usually placed with a part of their edge immediately in front of a room wall, wherein the non-concealed part of the room wall is then tiled. Between the installation object and the wall, an elastic sound insulation strip is advantageously arranged in order to prevent the direct transmission of structure-borne noise to the wall. Furthermore, the joint between the installation object and tiles usually with a permanently elastic material such. B. silicone sealed. However, the problem is to be observed that after a long time by the work of the building and in particular a lowering of the installation object, the said joints can rupture. Moisture can then get to the wall and sometimes cause considerable damage.

To solve this problem is in the EP 0 748 179 B1 a water-impermeable Zargenband proposed, which can be glued with its lower edge to the edge of a tub and is up above the tub edge. Moisture, which migrates through possibly leaky silicone joints towards the wall, should be prevented by the protruding part of the Zargenbandes at a contact with the wall. In practice, however, shows that this measure is often not sufficient and moisture can also get over the frame band away to the wall.

Furthermore, the DE 201 21 477 U1 a sealing tape with a film-like carrier strip, on the room-side front side parallel to each other two spaced sealing strands are arranged. According to a first use form of the sealing strip, the sealing strands are glued around the edge of a tub rim, while the carrier strip and a reinforcing strip projecting upwards stand vertically above the edge of the tub. In a second embodiment, the sealing tape is rotated 180 °, with the outer sealing strand adhered to the upper horizontal tub edge and the inner sealing strand adhered to the vertically downturned leg of the tub rim, and with the carrier strip and the reinforcing strip extending from the tub edge extend down. Behind the tiles located above the tub no part of the sealing strip is arranged in this case.

Against this background, it was an object of the present invention to provide a connection between a sanitary fixture and a wall, which provides improved protection against the penetration of moisture to the wall.

This object is achieved by a wall connection with the features of claim 1, and by a method having the features of claim 7. Advantageous embodiments are contained in the subclaims.

• a) Einen wasserundurchlässigen Dichtungsstreifen, welcher vorzugsweise aus einem Kunststoff wie beispielsweise Polyethylen, einem Schaumkunststoff und/oder einem Vliesstoff besteht.
• b) Wannenbefestigungsmittel zur dichten Verbindung des Dichtungsstreifens mit einem Rand des Einbaugegenstandes. Die Wannenbefestigungsmittel sind typischerweise an einem unteren Rand des Dichtungsstreifens angeordnet, wobei die Ortsangabe "unten" sich auf den herkömmlichen montierten Zustand des Fugenbandes bezieht. Die Wannenbefestigungsmittel können im einfachsten Fall aus einer Oberfläche bestehen, die sich z. B. mittels eines Klebers mit dem Einbaugegenstand verbinden lässt.
• c) Ein Kapillarstopp-Mittel, welches an dem Dichtungsstreifen angeordnet ist (zumindest in seinem ursprünglichen, unverarbeiteten Zustand) und welches dazu dient, ein Aufsteigen von Flüssigkeit in Material vor dem montierten Dichtungsstreifen zu verhindern.

To explain the invention, first a joint tape for the connection of a sanitary installation article such as in particular a basin or a tub to a wall is described, which can be used in the production of the wall connection according to the invention and in carrying out the method according to the invention. As its name implies without limitation to generality, the joint tape typically has an elongated shape with a longitudinal direction in which it continues, theoretically endlessly. The joint tape comprises the following components:

• a) A waterproof sealing strip, which preferably consists of a plastic such as polyethylene, a foam plastic and / or a nonwoven fabric.
• b) tray attachment means for sealingly joining the weather strip to an edge of the installation article. The trough fasteners are typically located at a lower edge of the weather strip, with the location "bottom" referring to the conventional assembled state of the seam tape. The trough fastening means may in the simplest case consist of a surface, which is z. B. can connect by means of an adhesive with the installation object.
• c) A capillary stop means disposed on the sealing strip (at least in its original, unprocessed state) and serving to prevent liquid from rising in material in front of the assembled sealing strip.

Through the use of the capillary stop means, the joint tape prevents liquid penetrating up to the sealing strip from being pulled upwards against the force of gravity by capillary action and reaching beyond the edge of the sealing strip. In practice it turns out that such a capillary transport is exerted, for example, by tile adhesive with which tiles are fastened to the wall above the installation object. The arrangement of an over the edge of the built-article standing out seal strip alone is therefore not sufficient to safely prevent the ingress of moisture to the underlying wall. However, this is achieved by the capillary stop means.

The capillary stop means may in particular comprise a capillary stop band, i. H. a strip of material extending in the longitudinal direction of the joint strip, which is arranged (usually spaced from the trough fastening means) on the sealing strip and in which no liquid ascension by capillary action is possible. The Kapillarstoppband may in particular be arranged at the upper edge of the sealing strip and optionally stand on this edge upwards. The aforementioned "liquid ascent by capillary action" refers to the direction from the tub attachment means to the capillary stop band, i. H. in a direction transverse to the longitudinal direction of the joint tape. As a rule, this is the vertical direction in the assembled state of the joint tape. Although in principle no more than one impermeability of the capillary stop band in this one direction is required, the capillary stop band will typically be impermeable in any direction for the capillary transport of liquid.

The capillary stop means may additionally or alternatively to the mentioned capillary stop band also comprise a release strip detachable from the sealing strip. After mounting the installation object with the joint tape and the full-surface application of a (tile) adhesive layer, such a release strip can be detached from the joint tape to produce a continuous, strip-like interruption of the tile adhesive layer in a particularly simple manner. Kapillarwege through the tile adhesive over the upper edge of the Seal strip also be effectively interrupted in this way. The width of the peel strip should be chosen so that the desired interruption effect is sufficiently guaranteed without removing too much tile adhesive. Typically, therefore, the width of the peel strip is in a range of about 5 mm to 30 mm, more preferably about 10 mm.

1. a) Der Dichtungsstreifen ist dichtend mit einem Rand des Einbaugegenstandes verbunden.
2. b) Der Dichtungsstreifen steht in vertikaler Richtung nach oben über den genannten Rand des Einbaugegenstandes hinaus.
3. c) Der Dichtungsstreifen weist in dem überstehenden Bereich Mittel zur Verhinderung des Aufsteigens von Flüssigkeit in Material vor dem montierten Dichtungsstreifen auf. Gemäß den obigen Erläuterungen können diese Mittel insbesondere in einem Kapillarstoppband bestehen, in dem kein Aufsteigen von Flüssigkeit durch Kapillarwirkung möglich ist. Alternativ oder zusätzlich können die Mittel eine streifenförmige Unterbrechung des Materials vor dem Dichtungsstreifen aufweisen, so dass keine Flüssigkeit durch Kapillarwirkung in diesem Material aufsteigen kann. Eine solche Unterbrechung kann wie erläutert insbesondere mit Hilfe eines Abziehstreifens erzeugt werden.

The wall connection according to the invention of a sanitary installation object to a wall comprises a water-impermeable sealing strip with the following properties:

1. a) The sealing strip is sealingly connected to an edge of the installation object.
2. b) The sealing strip protrudes vertically upward beyond the said edge of the installation object.
3. c) The sealing strip has in the protruding region means for preventing the rise of liquid in material in front of the mounted sealing strip. According to the above explanations, these means may consist, in particular, in a capillary stop band, in which liquid can not ascend by capillary action. Alternatively or additionally, the means may comprise a strip-like interruption of the material in front of the sealing strip, so that no liquid can rise by capillary action in this material. Such interruption can be generated as explained in particular with the aid of a Abziehstreifens.

Such a wall connection can be generated particularly easily with a joint tape of the type described. However, it can also be made in a variety of other ways, for example by using a separate weather strip, a separate Kapillarstoppbandes and the required connecting means (adhesive layers, etc.).

1. a) Der Dichtungsstreifen ist dichtend mit einem Rand des Einbaugegenstandes verbunden.
2. b) Der Dichtungsstreifen steht in vertikaler Richtung nach oben über den genannten Rand des Einbaugegenstandes hinaus.
3. c) Der Dichtungsstreifen ist über Wandbefestigungsmittel mit der Wand verbunden.

Advantageously, the wall connection of a sanitary fixture to a wall contains a water-impermeable weather strip with the following properties:

1. a) The sealing strip is sealingly connected to an edge of the installation object.
2. b) The sealing strip protrudes vertically upward beyond the said edge of the installation object.
3. c) The weather strip is connected to the wall via wall fasteners.

The wall connection thus has the advantage that it both on the one hand with the installation object and on the other hand with the underlying wall connected is. Therefore, if liquid gets beyond the top edge of the weather strip, it can not migrate down the back of the weather strip since the weather strip is bonded to the wall. As mentioned, it is of course particularly advantageous if in addition a capillary stop means is provided, which prevents the advance of liquid to the upper edge of the joint strip from the outset or reduced to a minimum.

In the following, various advantageous embodiments of the wall connections are explained according to the invention.

Thus, in a first advantageous embodiment, the capillary stop band is formed with a thickness which corresponds at least to the thickness of a (typical) tile adhesive layer. In particular, the Kapillarstoppband may have a thickness of more than 1 mm, preferably more than 2 mm. If, as usual, wall tiles are placed above the fixture on the wall, the stated thicknesses of the capillary stop tape ensure that the capillary stop tape extends in a space-filling manner from the wall to the tile, thus leaving no room for another layer of tile adhesive. Such a layer of tile adhesive running parallel to the capillary stop band could in fact represent a moisture bridge, via which possibly water could ascend past the capillary stop band by capillary action.

For the Kapillarstoppband different materials are suitable, provided that they ensure the desired interruption of Kapillartransportes of moisture. In particular, the Kapillarstoppband consist of a closed-cell foam, such as a polyethylene foam. The closed porosity of the foam ensures that there are no capillary paths through the material and that the material is elastic at the same time. The latter is important in order to be able to compress the capillary stop band to the thickness of the respective tile adhesive layer if necessary.

According to another embodiment of the invention, the sealing strip on the room side at least partially have an adhesion-promoting structure, in particular a non-woven structure. A tile adhesive can then be applied to such a structure and adhere, so that tiles can also be glued to the weather strip.

Furthermore, optionally at least one of the components of the joint strip-in particular the sealing strip and / or the capillary stop band-is elastic, preferably in a direction transverse to the longitudinal direction of the joint strip. This ensures that the joint strip can change in width and thus can follow setting movements of the installation object.

The trough fastening means and / or the wall fastening means may in particular comprise a self-adhesive strip, which typically (in the case of the separate joint tape) is covered by a peel-off protective strip until it is installed on site. Likewise, the tray attachment means and / or wall attachment means may also comprise a hot melt adhesive which is suitably applied between the weather strip and the installation article or wall.

According to another embodiment of the invention, a sound-absorbing profile can be arranged in the region of the tub fastening means. The sound-absorbing profile can be integrated, for example, in the joint tape. However, it may also be a separate product, which is first attached to the edge of the installation object and then in turn the trough fastening means are attached. The soundproofing profile prevents or reduces the transmission of structure-borne noise between the installation object and the wall.

• a) Die dichtende Verbindung eines wasserundurchlässigen Dichtungsstreifens mit einem Rand des Einbaugegenstand derart, dass der Dichtungsstreifen in vertikaler Richtung nach oben über den Rand des Einbaugegenstandes hinaus steht.
• b) Die Anbringung von Platten auf den an der Wand anliegenden Dichtungsstreifen mit Hilfe einer zwischenliegenden Kleberschicht, wobei diese Kleberschicht in einem streifenförmigen Bereich vor dem Dichtungsstreifen unterbrochen ist. Der streifenförmige Bereich soll dabei in Richtung der Längserstreckung des Dichtungsstreifens verlaufen.

The invention further relates to a method for connecting a sanitary installation object such as in particular a trough to a wall, comprising the following steps:

• a) The sealing connection of a waterproof sealing strip with an edge of the installation object such that the sealing strip in vertical upward direction beyond the edge of the installation object.
• b) The application of plates on the wall applied to the sealing strip with the aid of an intermediate adhesive layer, said adhesive layer is interrupted in a strip-shaped area in front of the sealing strip. The strip-shaped region should run in the direction of the longitudinal extension of the sealing strip.

The interruption of the adhesive layer in front of the sealing strip prevents capillary transport of liquid through the adhesive layer beyond the sealing strip. The strip-shaped region can be produced in various ways, for example by paying attention from the outset when applying the adhesive layer that no adhesive gets into this region. It is easier to apply an adhesive layer over the entire surface first and then remove the adhesive in the strip-shaped area again, as long as it is not cured. The latter method can be carried out very clean and comfortable with the help of a strip on the sealing strip. The release of this Abziehstreifens then automatically removes a correspondingly wide strip of the adhesive layer.

• Die raumseitige Anordnung eines Kapillarstoppbandes, in dem kein Aufsteigen von Flüssigkeit durch Kapillarwirkung möglich ist, am Dichtungsstreifen (zumindest) oberhalb von dessen Verbindung zum Einbaugegenstand.
• Die Anbringung von Platten (z. B. Fliesen) an der Wand derart, dass das Kapillarstoppband sowohl die Platten als auch die Wand kontaktiert.

Furthermore, a strip-shaped, adhesive-free area can also be achieved by the following two steps:

• The room-side arrangement of a Kapillarstoppbandes in which no rising of liquid by capillary action is possible, at the sealing strip (at least) above its connection to the installation object.
• The attachment of panels (eg tiles) to the wall such that the capillary stop band contacts both the panels and the wall.

The described methods generally relate to the manufacture of wall connections according to the invention. For further explanation of the methods and their possible developments, reference is therefore made to the above description.

FIG. 1 shows schematically and partially in section a bathtub 10, which is installed with two sides in a corner of a wall 20, wherein the wall 20 is covered in the finished state above the tub by tiles 21. The preparation of the wall connection for the tub 10 using a joint strip 40 according to the invention will be described below with reference to the FIGS. 1 to 3 explained in more detail.

• einen Dichtungsstreifen 42, welcher wasserundurchlässig ist und z. B. aus PE bestehen kann;
• eine (Heißschmelz-)Kleberschicht 41, welche raumseitig am (im montierten Zustand unteren) Rand des Dichtungsstreifens 42 aufgetragen ist;
• ein Kapillarstoppband 43, welches am oberen Rand des Dichtungsstreifens 42 angebracht ist und nach oben über den Dichtungsstreifen hinaus steht; das Kapillarstoppband 43 kann beispielsweise aus einem geschlossenporigen PE-Schaum bestehen und soll intern keinen Feuchtigkeitstransport zulassen;
• eine (Heißschmelz-)Kleberschicht 44, welche wandseitig auf der Rückseite des Kapillarstoppbandes 43, optional auch auf der Wandseite des Dichtungsstreifens 42, aufgebracht ist. Über die Kleberschicht 44 kann das Fugenband 40 an einer (verputzten) Wand 22 befestigt werden.

First of all, it can be seen in the cited figures that the trough 10 has a bent-over edge with a horizontal upper side 11, a vertical outer side 12 and a horizontal lower side 13. Around this edge, a sound insulation 30 is glued in a conventional manner, which may for example consist of a closed-cell, a few millimeters thick polyethylene foam. It serves to prevent the transmission of structure-borne noise between the tub and the wall. The sound-absorbing profile 30 has in particular a region 32 which adheres to the vertical outer side 12 of the tub rim and provides the actual sound insulation. In addition, it has a protective strip 31 which removably sticks to the horizontal top 11 of the tub rim and protects it during assembly or tiling from damage. Like the right mission picture in FIG. 1 shows, the protective strip 31 is removed after tiling. The cut of FIG. 3 further shows that a joint tape 40 (eg by means of a hot-melt adhesive) has already been applied to the sound-insulating region 32 of the sound-insulating profile. The joint tape 40 essentially contains the following components:

• a weather strip 42, which is impermeable to water and z. B. may consist of PE;
• a (hot melt) adhesive layer 41, which is spatially applied on the (in the assembled state lower) edge of the sealing strip 42;
• a capillary stop band 43 which is attached to the upper edge of the weather strip 42 and projects upwardly beyond the weather strip; the Kapillarstoppband 43 may for example consist of a closed-cell PE foam and internally should not allow moisture transport;
• a (hot melt) adhesive layer 44 which on the wall side on the back of Kapillarstoppbandes 43, optionally also on the wall side of the sealing strip 42, is applied. The adhesive tape 44 can be used to fasten the joint tape 40 to a (plastered) wall 22.

In FIG. 4 It is shown how the tub 10 has been moved to its installation position on the wall 22. The sound-absorbing profile 30 and the joint tape 40 come into contact with their adhesive layers, so that the joint tape 40 is sealingly connected to the sound-insulating profile 30 - and therefore also to the edge of the bath.

Furthermore, a tile 21 is glued in front of the wall 22 over layers 23a, 23b of tile adhesive. In order to improve the adhesion of the tile adhesive 23b to the sealing strip 42, the latter may be provided on the room side with an adhesion-promoting structure (for example a fleece). It is important that the Kapillarstoppband 43 is at least as thick as the layers of tile adhesive 23a, 23b, so that it is space-filling between the wall 22 and tile 21 and there leaves no more space for tile adhesive. Typically, the capillary stopband 43 is elastic and slightly thicker than the final tile adhesive layer so that it will be slightly compressed in the assembled state.

FIG. 4 further shows the sealing of the transition between trough 10 and tile 21 by a permanently elastic material 24, for example silicone. As long as this silicone joint 24 adheres to both the tub 10 and the tile 21, the connection area is protected against the ingress of moisture to the wall 22.

FIG. 5 but shows the connection area of FIG. 4 as it typically appears after a long time (usually a few years). Due to unavoidable building movements and in particular by a lowering of the tub 10, the silicone joint 24 is torn. Due to the resulting gap 25 moisture can therefore penetrate towards the wall. The weather strip 42 of the joint tape prevents this moisture can penetrate directly into the wall. Furthermore, the bonding of the sealing strip 42 with the sound insulation profile or the edge of the tub prevents the moisture from being able to penetrate further downwards. Due to a capillary action in the tile adhesive 23b, however, it is possible for the moisture to rise upwards in front of the sealing strip 42 against the force of gravity. However, penetration of the moisture up to the wall 22, ie beyond the sealing strip 42, is also prevented here by the capillary stop band 43, which interrupts the tile adhesive and does not permit liquid transport. Even with the inevitable occurrence of cracks in the silicone joints, therefore, the wall 22 is permanently protected against the ingress of moisture.

In the FIGS. 6 to 9 a second embodiment of a joint tape 140 according to the invention is shown, wherein the same or denoted by 100 reference numerals designate identical or similar parts as in the preceding figures.

• Einen wasserundurchlässigen Dichtungsstreifen 142.
• Eine Kleberschicht 141, welche raumseitig am im montierten Zustand unteren Rand des Dichtungsstreifens 142 aufgetragen ist.
• Einen Abziehstreifen 143, welcher im oberen, im montierten Zustand über den Wannenrand hinausstehenden Bereich des Dichtungsstreifens 142 angeordnet ist und sich in Längsrichtung parallel entlang des gesamten Dichtungsstreifens erstreckt. Der Abziehstreifen 143 ist lösbar mit dem Dichtungsstreifen 142 verbunden, beispielsweise über einen (schwachen) Adhäsivkleber. Der Abziehstreifen 143 kann aus einem Kunststoff wie beispielsweise PE bestehen.

In FIG. 6 the second joint tape 140 is shown separately in a cross section. It basically contains the following components:

• A waterproof sealing strip 142.
• An adhesive layer 141, which is spatially applied to the lower edge of the sealing strip 142 in the assembled state.
• A release liner 143 which is disposed in the upper portion of the weather strip 142 projecting beyond the tub rim in the assembled state and extends longitudinally in parallel along the entire weather strip. The release liner 143 is releasably connected to the weather strip 142, for example, via a (weak) adhesive adhesive. The tear strip 143 may be made of a plastic such as PE.

Optionally, the joint tape 140 may be provided with further components, for example a wall-side adhesive layer at the upper edge (corresponding to layer 44 of the first joint strip 40) and / or a sound insulation profile on the room side or wall side.

FIG. 7 shows the joint tape 140 after it has been glued with its lower adhesive layer 141 to the folded, vertical edge of a trough 10. Between the glued joint tape 140 and a wall can optionally be arranged a sound insulation (not shown) by, for example, it is glued to the back of the joint tape 140.

FIG. 9 a) shows in perspective a shower tray 10 with glued joint tape 140 after reaching the wall and after full-surface application of a tile adhesive layer 23 on the wall from the top of the tub 10. The tile adhesive layer 23 initially covers the entire over the tub rim upstanding part of the sealing strip 142 including the Stripping strip 143 from. However, as shown, after the tile adhesive 23 has been applied, the release strip 143 is released from the weather strip of the joint strip, thereby removing the portion of the tile adhesive present on that strip. In this way, a continuous, tile-free strip 143 '( FIG. 8 ) generated.

FIG. 9 b) shows the installation process after application of tiles 21 on the tile adhesive 23rd

FIG. 8 represents a cross section through the finished wall connection, which was prepared by means of a joint strip 140. The sealing strip 142 of the joint strip 140 rests directly on the wall 22 and is glued in the lower region at the edge of the trough 10. In front of the sealing strip 142, tile adhesive is present in layers 23a and 23b, which are separated from each other by an adhesive-free cavity or strip 143 '. As explained above, this strip 143 'has been produced by removing the release liner 143 from the original joint tape. On the tile adhesive 23a, 23b, a tile 21 is applied, wherein the joint between tile 21 and trough 10 is sealed with a silicone strip 24.

Should the silicone joint 24 become leaky after some time, water can penetrate under the tile 21 in the direction of the wall. However, a capillary rise of liquid through the tile adhesive behind the tile 21 is only possible in the lower region of the tile adhesive 23b, since a further ascent by the adhesive-free region 143 'is prevented.
