Description

The present invention relates to a shower channel installation set or a built-in shower channel arrangement, as it is used in particular when creating a floor-level shower floor. The invention also relates to a method for installing or using the shower channel installation kit.

Such shower drain kits usually include a shower drain with a drain connector that can be inserted into a drain body of a siphon. The drain housing is preferably relatively flat and the waste water is usually drained off to the side. The shower channel, in turn, usually stands on height-adjustable feet and, once the height has been adjusted, is lined with cement or other lining material.

The qualitative requirements for such a shower channel installation kit or the result of the installed shower channel are numerous and different. For example, in order to achieve good and sustainable structural stability, it is essential that the padding fills the space between the shower channel and the screed or raw concrete of the wet room fully and without cavities.

Another important criterion is the achievement of good and lasting tightness. It must be avoided that water can penetrate next to or along the flanges of the shower channel.

The measures and work steps, in turn, to achieve good lining and good tightness, should not, however, at the same time get out of hand and make the use of the shower channel installation kit too complicated.

Last but not least, the avoidance of sound bridges is another important criterion. However, a lining that comes into more or less direct contact with the underside of the shower channel creates a sound bridge. Height-adjustable feet, which are attached more or less directly to the body of the shower channel or to the underside of the shower channel flange, also tend to create such sound bridges, perhaps less via the mostly dampened lower foot sockets, but simply due to the fact that the threaded rods of such feet make contact can get to the relining material.

A shower channel installation kit with adjustable feet is out, for example EP2700342 A known.

The object of the present invention is to provide a shower drain installation set that satisfies the above criteria in an improved manner. Disadvantages of known shower channel installation kits should be completely or largely eliminated if possible.

The solution to the problem consists first of all in the conception or arrangement of at least one shower channel in a substructure or shower channel base body, cast therein according to the invention.

Furthermore, according to the invention, height-adjustable feet are not arranged on the shower channel, but rather on this substructure or shower channel base body in an upper attachment point of the respective height-adjustable foot. This upper attachment point is preferably realized by internally threaded sleeves, for example metallic sleeves, being arranged in the material of the substructure or shower channel base body or preferably being cast again. However, the internally threaded sleeves can also just be inserted or glued in, welded or screwed in.

According to the invention, threaded rods can also be screwed into these internally threaded sleeves. The internal thread sleeves are depending on the desired attachment height of the shower channel can basically be used in any length, but it is preferred to supply three different prefabricated lengths with a shower channel installation kit according to the invention.

The advantage of this described arrangement with internally threaded sleeves of different lengths is that the threaded rods of the height-adjustable feet, which can be screwed into the internally threaded sleeves, always have an improved, because deeper, attachment point in this way. In other words, the internal thread of the internally threaded sleeve always reaches down as far as possible. The shower channel can thus be aligned much more stably during installation and lining than would be possible if the threaded rods were attached a few centimeters higher on the underside of the shower channel. In addition, a sound bridge between the metal threaded rod and the metal shower channel body or the metal shower channel flange is largely eliminated because the internally threaded sleeves are not in direct contact with the shower channel body or the shower channel flange, but in the material of the substructure - Or shower channel base body are used or cast. The material of the substructure or shower channel base body is preferably cast plastic and the material of the internally threaded sleeves can be metal, but also plastic or CFRP.

The height-adjustable threaded feet comprise on the underside of the threaded rod preferably rotatably arranged foot sockets with sound-insulating material inserts arranged on the underside.

A shower channel installation set according to the invention also preferably comprises a soundproofing mat which has cut out or punched out holes for the foot pedestals of the height-adjustable feet. This sound decoupling mat is placed on the screed or raw concrete of the wet room. Furthermore, a shower channel installation set according to the invention can have sound decoupling or protective panes include, which are preferably made of the same material as the sound decoupling mat. These sound decoupling or protective discs have a central hole and a radial slot and can be placed around the threaded rod on the base. Furthermore, insulating sleeves can also be provided from a flexible and insulating material, with an axial slot. These insulating sleeves can be placed on the threaded rods. All of these measures serve to avoid sound bridges between the mainly metallic components of the shower channel arrangement and the lining material, but also to protect against dirt and sticking of the rotatable parts of the threaded rod and rotatable base.

As already mentioned, the substructure or shower channel base body of a shower channel installation kit according to the invention is preferably cast from plastic and is also preferably shaped as a three-dimensional lattice profile or has a honeycomb structure in order to save weight and material, but also in order to increase bending strength. However, it is also possible to cast the substructure or shower channel base body from a solid material.

Furthermore, a shower channel installation set according to the invention comprises at least one sealing and crack-bridging non-woven fabric, which is preferably cast in between the flange of the shower channel and the substructure or shower channel base body. This sealing and crack-bridging fleece is still elastic and preferably loosely overlaps the parts of the substructure or shower channel base body that extend beyond the flange of the shower channel.

• Auf der Oberseite des Duschrinnen-Flansches.
• Wie bereits beschrieben, zwischen der Unterseite des Duschrinnen-Flansches und der Oberseite des Duschrinnen-Grundkörpers.

However, it is also possible to provide several sealing and crack-bridging fleeces arranged one on top of the other. The following are possible mounting locations:

• On the top of the shower channel flange.
• As already described, between the bottom of the shower channel flange and the top of the shower channel body.

The elastic sealing and crack-bridging fleece arranged according to the invention not only improves the tightness of the shower channel arrangement, but also its longevity. Even the finest cracks, which can occur over time between different materials with different thermal expansion coefficients and hygroscopic properties, are not only bridged, but also prevented from occurring.

A shower channel installation set according to the invention is preferably supplied with the sealing and crack-bridging fleece wrapped in it. In this way, the shower channel body is freely accessible for attaching accessories or the pre-assembly brackets or the profile rail. Furthermore, the shower channel is protected against dirt or adhesion for the installation work steps up to before the sealing and crack-bridging fleece is unfolded when the final bonded seal is made or the tiles are laid.

The sealing and crack-bridging fleece can basically be provided or reinforced with a cut protection strip on all sides of the shower channel flange, but preferably in particular on that side which adjoins a connecting wall in the case of wall mounting. This cut protection strip is preferably a thin and flexible metal sheet, perforated or in its entirety, or a metal grid or mesh that is so tough or cut-resistant that it cannot be cut, or only with great difficulty, with a knife or carpet knife. The cut protection strip can only extend over a section of the sealing and crack-bridging fleece or it can also be glued over the entire surface to the top and/or underside of the sealing and crack-bridging fleece or it can also be woven or cast into the material. This protection against Cutting can be advantageous wherever a silicone joint is to be applied as a final step. If, for example, a silicone joint should have cracked, discolored or even become moldy in a few years, it is usually cut away with a knife or carpet knife. The cut protection strip prevents the sealing and tear-bridging fleece from being cut as well.

A further preferred embodiment variant of a shower channel installation set according to the invention also comprises separate fleece adhesive strips, preferably also made of an elastic material. These fleece adhesive strips at least partially overlap the edges of the flange of the shower drain in an adhesive manner. On the one hand, this serves to improve the tightness of the installed shower channel installation kit or the shower channel arrangement overall, but on the other hand it also improves the adhesion of the tiles or floor panels, which partially cover the shower channel flange in the final installed state.

In addition to the feature that the substructure or shower channel base body is preferably cast from plastic, which generally transmits sound worse than other materials, the substructure or shower channel base body can be partially or completely wrapped in sound-insulating material or be lined with such.

The substructure or shower channel body can form four side surfaces. In a further embodiment variant of a shower channel installation set according to the invention, at least one profile rail can preferably be arranged on at least one of these side surfaces, which is incorporated into the lining cement or material and thus improves the seat of the shower channel.

A further embodiment variant of a shower channel installation kit according to the invention provides for mounting the shower channel on a connection wall that at least two Pre-assembly angles can be slidably arranged, for example by means of a slotted attachment. After pre-assembly or positioning of the shower channel, these pre-assembly brackets are removed again.

The shower channel has at least one drain connector, which is inserted into a suitable receptacle of a separate siphon drain body in a corresponding work step when installing a shower channel installation set according to the invention. In a further embodiment variant of a shower channel installation kit that is also according to the invention, the siphon drain housing is not separate but integrated into the shower channel base body, preferably inserted or cast in again.

The disclosed different design variants of a shower channel installation set according to the invention can be combined with one another as desired with regard to the features that are not relevant to the basic function. For example, the design variants with or without height-adjustable feet with threaded rods in internally threaded sleeves can be combined equally and reciprocally with one another with the design variants that have a shower channel base body in the form of a three-dimensional lattice profile or a sealing and crack-bridging fleece, with or without cut protection strips, between the shower channel flange and the shower channel body or non-woven adhesive strips on the upper side of the shower channel flange. All the design variants listed, but also the combined design variants that result from the possible combinations, can be combined equally and reciprocally with one another with the design variant that provides a sound-insulating lining of the shower channel base body, as well as with the one that has a profile rail or at least two pre-assemblies - Angle includes.

As shown, both attachment points BP ₂ and BP ₃ are distally outside the area of the shower channel flange 2c. On the left side, a less wide shower channel base body 5d may also be desired in order to connect with the shower channel 1c as close as possible to the connecting wall 27, but in any case on the right side, the attachment point BP ₃ is not only below, but also distally outside an imaginary vertical V from the side edge of the shower channel flange 2c.

Optionally, a cut protection strip 34 can be provided on the wall side or on all 4 sides of the shower channel flange. For example, in such a way that it is glued in the form of a thin, flexible but cut-resistant sheet metal, a mesh or a grid on the upper side of the sealing and crack-bridging fleece 6e. After removing the pre-assembly bracket 17a and folding out the sealing and crack-bridging fleece 6e, the cut protection strip provides protection against cutting, particularly at a corner edge 35 between the connecting wall 27 and the shower channel base body 5d, for example if a silicone joint (not shown) arranged in this corner edge 35 is to be replaced later and is therefore cut away with a knife.
