Description

The invention relates to a sealing collar for a shower drain system with floor drain according to the preamble of claim 1, a sealing system for a shower floor element according to claim 9, a set comprising a sealing system and a shower floor element according to claim 14, and a method for producing a base for a wet cell according to claim 15th

In order to produce a wet room for a shower, it is customary to lay a substructure before installing a shower tray or laying tiles in the case of barrier-free showers. This substructure is often formed by a shower tray element serving as a pedestal member and configured to provide a floor drain which is connected to an existing drainage conduit and arranged so that the shower tray member surrounds the floor drain and the connection to the drainage conduit in the drainage conduit Shower floor element can be performed. When installing a shower tray or laying a floor covering, it must now be ensured that the entire wet cell area is reliably sealed, so that shower water is led into the floor drain and can not run into the floor beneath the wet room. For this purpose, in the art often sealing foils are used, which are laid on the substructure to provide a water-impermeable barrier layer.

However, the laying of such a sealing film is associated with considerable effort. To address this problem, for example, in the EP 1712 169 A1 proposed that the sealing film manufacturer already on the shower floor element to install, so that the laying of the sealing film is eliminated. However, this results in some disadvantages. First, it is difficult to reliably seal the sealing foil against the floor drain. Furthermore, the expansion of the sealing film is limited to the extent of the shower floor element. There is thus no protruding film available that can be used to form a wall connection or a watertight transition between the wet cell area and the bath floor.

An object of the present invention is therefore to provide a solution for sealing a shower area with a floor drain, which can ensure a reliable seal over the entire shower area, which is suitable for various types of floor drains and is uncomplicated in handling and assembly.

The object is achieved by a sealing collar for a shower system with floor drain according to claim 1, a sealing system for shower floor elements according to claim 9, a set according to claim 14, and a method according to claim 15.

The object is achieved in particular by a sealing collar for shower systems with floor drain, comprising a Sifondichtung which is connectable to the floor drain of the shower system, and arranged on the outer periphery of the Sifondichtung sealing foil portion, wherein the sealing foil portion welded in particular manufacturer side with the siphon seal or glued or made in one piece is, such that a watertight connection between the Sifondichtung and the sealing foil portion is created before installation, and wherein the sealing foil portion is formed connectable to a shower tray element which is arranged around the floor drain of the shower system.

A core idea of the invention is that a required water-impermeable barrier layer on the shower floor element and also a necessary sealing of the floor drain through a single component be effected. As a result, on the one hand, the assembly cost is significantly reduced, on the other hand, a higher reliability of the seal can be ensured because a sealing of the barrier layer with respect to the process is no longer necessary. The sealing foil section is thereby automatically correctly positioned when connecting the siphon seal to the floor drain. Leaks between the floor drain and the barrier can not occur.

Preferably, the sealing foil portion is formed flat, has an upper side and a lower side and extends radially from the Sifondichtung. As a result, a flat barrier layer is formed directly on the shower floor element.

In a preferred embodiment, the top and / or the bottom of the sealing film portion are self-adhesive. By a self-adhesive underside of the sealing film section, the sealing collar is connected and fixed in addition to the underlying shower floor element when connecting to the floor drain. As a result, inadvertent detachment or slipping of the sealing collar during further assembly can be suppressed, thereby avoiding leaks between the sealing collar and the floor drain. If the upper side of the sealing film section is self-adhesive, covering elements can be connected and fixed in a simple manner to the barrier layer formed by the sealing film section during further assembly. As a result, the installation effort is further reduced and prevented possible errors during installation due to slippage of other cover.

It is preferable that a characteristic expansion amount of the sealing foil portion is at least five times as large, preferably at least ten times as large, more preferably at least twenty times as large as the diameter of the opening of the siphon seal. By the characteristic extent of expansion is meant essentially a diameter of the surface which is defined by the sealing foil section extending radially from the siphon seal. For example, if the outer contour of the sealing film portion is circular, the characteristic expansion amount is the circle diameter. For rectangular or square sealing foil sections, under the characteristic extent of expansion, a

To understand page length. With such a large sealing foil section, the entire shower area can be covered watertight and

In one embodiment, the siphon seal is connectable to the floor drain of the shower system by a plug connection. In this case, either the siphon seal can be plugged into the floor drain of the shower system, or the siphon seal can be plugged onto the floor drain of the shower system. This represents a particularly simple solution for producing the connection between the siphon seal and the floor drain.

In one possible embodiment, the siphon seal has latching devices which can interact with latching devices on the floor drain. The latching devices can be formed for example by arranged on the circumference of the floor drain locking grooves and corresponding grooves on the inside of the Sifondichtung. Alternatively, the Sifondichtung may have locking grooves on its outer circumference and the floor drain on its inner side corresponding latch grooves, so that the Sifondichtung can be inserted into the floor drain. By such locking devices, a stable connection between the siphon seal and floor drain is easy to manufacture.

In an alternative embodiment, the siphon seal can be screwed to the floor drain of the shower system. Even with this variant, a simple and stable connection solution is produced.

However, there are numerous other connection possibilities between the floor drain and Sifondichtung known, so that the present invention is not limited to attachable to the floor drain or screw-Siphon seals.

In a further embodiment, the sealing collar has at its upper edge a sealing projection extending radially outwards. This sealing projection can serve to seal the sealing sleeve in a simple manner against a drain opening in a cover element such as a shower tray. It is preferred that a distance between the top of the sealing foil sections and the sealing projection of the thickness of a shower tray corresponds to its drain opening, so that the sealing projection comes to rest on the edge of said drain opening with inserted shower tray. By Placing a siphon on the drain opening, the sealing sleeve can easily seal the drain opening of the cover, whereby the tightness is further increased.

The abovementioned object is achieved independently by a sealing system for a shower floor element, comprising a sealing collar of the type described above, and a sealing strip with a recess which can be arranged above the sealing collar attached to the floor drain, wherein the recess is dimensioned such that the sealing strip along the circumference of the recess can be connected to the sealing foil section along its outer circumference, in particular can be glued, such that the watertight barrier layer formed by the sealing foil section is widened by the sealing path. With this sealing system an even more flexible solution for different dimensions and geometries of the shower area can be realized. The sealing collar can be dimensioned so that the connection to the floor drain can be done easily and the barrier layer can be easily extended by gluing the sealing strip on the surface of the sealing film section.

In a preferred embodiment, the sealing web is made of a water-impermeable film.

The sealing web can be self-adhesive on at least one side. As a result, the assembly effort is reduced because no adhesive must be applied.

In a preferred embodiment, a bonding surface of the sealing film portion covered by the sealing sheet in the laid-up state forms 25%, preferably 50%, more preferably 75%, of the total area of the sealing film portion. By a large overlap area between the sealing film portion and the sealing sheet, the tightness of the barrier layer is increased. In addition, the laying of the sealing sheet is simplified if the connection surface is chosen to be large, since then a sufficient connection surface is maintained even with inaccurate positioning of the sealing sheet.

In a further preferred embodiment, the sealing film portion and the sealing web are dimensioned such that a barrier layer formed from sealing film portion and sealing sheet the underlying shower floor element completely covered, preferably extends beyond the shower floor element addition and forms a sealing sheet projection, in particular to form a wall connection and / or a watertight transition between the shower floor element and a bathroom floor. It must therefore be created no separate sealing solution for the wall or the subsequent bathroom floor. This simplifies the sealing of the shower area and increases the reliability of the seal, since no additional sealing elements are required, which would have to be connected to the sealing system.

The above object is further achieved independently by a kit comprising a sealing system for a shower tray element of the type described above, and a shower tray element having a recess which can be arranged such that the floor drain is received therein. With this set can be easily formed a substructure of a wet cell, which is easy to manufacture and is characterized by a high density.

In a preferred embodiment, the shower floor element is formed of particle foam, in particular rigid foam. Thus, a shower floor element is created, which is characterized by low weight and high resilience.

• Positionieren der Dichtmanschette auf dem Duschbodenelement derart, dass der Dichtfolienabschnitt der Dichtmanschette auf dem Duschbodenelement aufliegt und die Sifondichtung der Dichtmanschette über dem Bodenablauf angeordnet ist bzw. mit diesem verbunden ist.

Independently, the above-mentioned object is also achieved by a method for producing a substructure for a wet cell, wherein the method can be carried out in particular using a sealing collar described above. The method comprises the following steps:

• Laying a shower floor element with a recess in which a floor drain is receivable;
• Positioning the sealing collar on the shower tray element such that the sealing foil portion of the sealing sleeve rests on the shower tray element and the siphon seal of the sealing sleeve is arranged above the floor drain or is connected thereto.

In one possible embodiment, the sealing collar is connected to the floor drain by inserting the siphon seal into the floor drain and / or by gluing the siphon seal to the floor drain.

In a further embodiment, after positioning the sealing collar on the shower tray element, a sealing strip with a recess is arranged above the sealing collar in such a way that the sealing strip overlaps the sealing foil section of the sealing collar along the circumference of the recess.

It is also possible to connect the sealing sheet with the sealing film portion, in particular to glue.

Further embodiments emerge from the subclaims.

Fig. 1a shows a sectional view of a sealing collar 10 according to a first embodiment of the invention. The sealing collar 10 consists of a siphon seal 11 and a sealing foil portion 12. The sealing foil portion 12 is formed on the outer periphery of the siphon seal 11 and extends radially outwardly therefrom. The sealing film section 12 starts at a lower end of the Sifondichtung 11, so that an upper side 13 in the installed state facing up and the sealing sleeve 10 rests on a bottom 14. At the upper end, the siphon seal 11 has a seal overhang 16 which extends radially outward from the upper edge of the siphon seal 11 and is substantially annular in the present embodiment.

In the Fig. 1a sealing collar 10 shown is placed or glued to a flange of the floor drain 40 for connection to a floor drain 40. The Sifondichtung 11 is made of a rubber or elastic plastic formed so that the lower end of the Sifondichtung 11 flush against the flange of the floor drain 40. With this Sifondichtung 11 so a universal sealing sleeve 10 is realized, which is usable in principle with any floor drains 40.

In the in Fig. 1b In the embodiment shown, the siphon seal 11 of the sealing collar 10 is extended downward beyond the attachment height of the sealing film section 12. The Sifondichtung 11 of the embodiment shown here can also be formed from an elastic material. But it is also possible to manufacture the lower end of the Sifondichtung 11 of a solid plastic. The dimensions of siphon seal 11 and floor drain are as in Fig. 1b shown so matched to each other that for connection to the floor drain 40, the sealing sleeve 10 can be easily inserted into the floor drain 40. In an alternative embodiment (not shown), the inner diameter of the Sifondichtung 11 corresponds to the outer diameter of the floor drain 40. Then, the Sifondichtung 11 can be plugged onto the floor drain 40. It can be provided on the Sifondichtung 11 and the bottom drain 40 additionally (not shown) locking grooves and locking grooves, which mesh with the bottom drain 40 when connecting the sealing sleeve 10 and stabilize the connection.

In Fig. 2a is a perspective view of a sealing collar 10 according to an embodiment of the invention shown. The sealing foil portion 12 has a square outer contour in this embodiment. This sealing collar 10 is advantageously suitable for use in a wet room with a likewise square floor plan. Accordingly, the in Fig. 2b shown embodiment of a sealing collar 10 are used with a circular sealing foil portion 12 for wet cells with a circular outline. In both figures, the upper end of the Sifondichtung 11 can be seen, which protrudes beyond the sealing film portion 12. It should be noted that the shape of the sealing foil portion 12 is not particularly limited, but may be selected in accordance with the geometry of the shower area in which the sealing collar 10 is to be inserted. It is also possible to choose the position of the siphon seal 11 asymmetrically on the surface formed by the sealing film section 12, if the floor drain 40 is placed asymmetrically in the shower area. It is only essential that the sealing film section 12 radially extends from the periphery of the siphon seal 11 to form a laminar barrier layer when the sealing collar 10 is connected to a floor drain 40.

In Fig. 3a and 3b are each the sealing collars 10 off Fig. 2a and 2b shown in plan view. Since with the sealing foil portion 12, a flat barrier layer is to be provided covering at least the majority of the wet cell area, the dimensions of the sealing foil portion 12 are significantly larger than the opening area of the Sifondichtung 11. Specifically, as a reference for describing the extent of the Sifondichtung the diameter of the opening of Sifondichtung d ₁₁ are used. To describe the extent of the sealing film portion 12, a characteristic expansion quantity d _{12 is} selected. In the case of the square embodiment of Fig. 2a and Fig. 3a is the characteristic dimension size d _12, the side length of the square sealing film portion 12. In the case of the circular embodiment of Fig. 2b and Fig. 3b is selected as a characteristic expansion amount d _12, the diameter of the circular sealing film portion 12. In both cases, d _{12 is} slightly more than five times larger than d ₁₁ . With these dimensions, the handling of the sealing collar 10 is relatively uncomplicated, but the extent of the barrier layer is already so great that a considerable part of the shower area can be sealed.

In order to further increase the barrier layer area, the sealing collar 10 may be combined with a sealing web 20 to form a sealing system. In Fig. 4a is a plan view of a sealing system according to an embodiment of the invention shown, in which the sealing web 20 is placed on the sealing sleeve 10. It will be the in Fig. 2a and 3a shown sealing collar 10 with square sealing foil portion 12 used. The outer dimensions of the sealing web 20 are larger than those of the sealing film section 12. The outline of the sealing film section 12, which lies below the sealing web 20, is indicated by dashed lines. The sealing path has a recess 21, which is arranged above the siphon seal 11, so that in the installed state, a connection to the floor drain 40 remains. The sealing strip 20 thus further increases the barrier layer formed by the sealing film section 12 to the outside, without the connection function of the siphon seal 11 being impaired. Both the upper side 13 of the sealing film section and an underside of the sealing web 20 can be self-adhesive, so that when the sealing web 20 is placed on the top directly a tight connection between the sealing sleeve 10 and the sealing sheet 20 is created.

In Fig. 4b For example, a sealing system using the round sealing collar 10 is off Fig. 2b and Fig. 3b shown. The sealing sheet 20 used here also has a circular outline and a circular recess 21 which is disposed above the siphon seal 11. The shape of the sealing strip 20, like the shape of the sealing foil section 12, is not subject to any particular restrictions and can in turn be chosen according to the geometry of the shower area. Also in the case of the sealing web 20, it is not necessary that the recess 21 is positioned centrally, it can also be an asymmetric positioning can be selected when the bottom drain 40 of the shower system is arranged asymmetrically on the sealed area. It is only necessary to ensure that the shape of the recess 21 is selected according to the shape of the sealing film portion 12 so that along the circumference of the recess 21, a sufficient areal connection to the sealing film portion 12 can be made.

In Fig. 5a and 5b each of the sealing systems are made Fig. 4a and 4b shown in a perspective exploded view. In both figures, d _{21 designates} a characteristic extent of expansion of the recess 21. In Fig. 5a d _{21 is} the side length of the square recess 21, in FIG Fig. 5b d _{21 is} the diameter of the circular recess 21. On the sealing collar 10, a connection surface 17 between the projection 21 of the recess 21 and the outer edge of the sealing film section 12 shown in dashed lines is drawn. If the sealing web 20 is placed on the sealing collar 10, the connecting surface 17 is the overlapping region to which the sealing web 20 and the sealing collar 10 are connected. In Fig. 5a and Fig. 5b the connection area makes up more than 50% of the total area of the sealing film section 12. The larger the connecting surface 17 is selected (the smaller the recess 21 is selected) the better is the connection between the sealing web 20 and the sealing collar 10. However, if the recess 21 is chosen to be too small, positioning of the sealing web 20 over the protruding part can take place the siphon seal 11 becomes difficult.

Together with a shower floor element 30, the sealing system just described forms a set for easy and reliable installation of a Substructure for a shower system. In Fig. 6 is such a set in the installed state shown in a sectional view. A bath floor 51 is bounded on the right side by a wall 50 and has a recess in which a shower floor element 30 is fitted. The shower floor element 30 has a recess in which a floor drain 40 is received. In Fig. 6 the floor drain 40 is formed directly in the bottom of the recess. However, it may also be provided a drain line in the wall 50. In this case, a drain is connected to the drain line and positioned in the recess of the shower tray element 30, wherein the drain line is guided in the shower tray element 30.

For connection to the floor drain 40 is in Fig. 6 a sealing collar 10 as in Fig. 1b shown used. The lower end of the Sifondichtung 11 is inserted into the floor drain 40. The sealing film portion 12 of the sealing sleeve 10 rests on the shower tray member 30 and is glued in the example shown with selbigem because the bottom 14 of the sealing film portion 12 is self-adhesive. It can be clearly seen that the installation of the sealing collar 10 is inexpensive because it is done by merely inserting the siphon seal 11 in the floor drain 40. At the same time, a watertight barrier layer is created by the sealing film section 12, which is connected in a watertight manner to the floor drain 40. Thus, with the sealing sleeve 10 in one step, a connection to the floor drain can be made while forming a barrier layer, the floor drain 40 and the barrier layer are automatically sealed by the one-piece design of the sealing sleeve 10.

The sealing foil portion 12 of the sealing collar 10 used here does not cover the entire shower tray element 30. Therefore, the barrier layer is expanded by the sealing web 20, which is positioned on the sealing collar 10 so that the recess 21 of the sealing web 20 is arranged around the siphon seal 11. The dimensions of the sealing strip 20 are greater than those of the shower tray element 30, so that on both sides of the shower tray element 30, a sealing sheet protrusion is formed beyond the base of the shower system formed by the shower tray element 30. On the side facing away from the wall 50 of the sealing sheet protrusion forms a watertight transition between the shower floor element 30 and the bath bottom 51, so that no water in a space between the shower floor element 30 and the Edge of the bath floor 51 can penetrate. On the wall 50 facing side of the sealing sheet protrusion forms a watertight wall connection, so that no further sealing elements must be used to seal the shower enclosure against the wall 50.

On the in Fig. 6 shown substructure can now be a shower tray or shower tray 60 are placed, which has a drain opening, which is arranged according to the position of the supernatant of the siphon seal 11. In Fig. 7 an enlarged view of such an arrangement in the region of the floor drain 40 is shown. The thickness of the shower tray 60 at the discharge opening corresponds to the distance between the upper side 13 of the sealing film section 12 and the sealing projection 16. Thus, the sealing projection 16 of the sealing collar 10 rests on the edge region of the drain opening of the shower tray 60. If a siphon (not shown) is now placed on the discharge opening, the sealing projection 16 is pressed onto the edge of the discharge opening and seals the sealing collar 10 against the shower tray 60, so that shower water is passed from the shower tray 60 into the floor drain 40 without leakage.

In Fig. 8 is a built-in substructure with a sealing collar 10 according to the in FIG. 1a shown embodiment shown. The floor drain 40 has a widened edge at its upper end and terminates flush with the shower floor element 30. The sealing collar 10 is placed here only on the floor drain 40 and is fixed by the self-adhesive bottom 14 of the sealing film portion 14 on the shower tray element 30, so that the positioning of the siphon seal 11 is fixed above the floor drain 40. To complete the shower floor area, the area above the shower floor element 30 can now be covered with tiles or another floor covering, so that a barrier-free shower can be created, or a shower tray can be used.

The sealing of the sealing collar 10 relative to the floor drain 40 is created at the widened edge of the floor drain 40. The underside 14 of the sealing film section 12 is also self-adhesive in the support region of the floor drain 40, so that the sealing collar 10 is sealed against the floor drain 40. In addition, a thread 41 is formed on the inner wall of the floor drain 40, in turn, in the (not shown) Sifon can be screwed. Analogous to in FIG. 7 shown embodiment the screwed siphon presses the sealing projection 16 of the sealing collar 10 onto the underlying floor covering or edge (not shown) of the drainage opening of a shower tray and thus seals the sealing collar 10 against the floor covering or the shower tray. At the same time, the siphon seal 10 is also pressed against the support surface of the floor drain 40 by the screwed-in siphon, thereby further increasing the tightness between the siphon seal 10 and the floor drain 40.

Overall, therefore, with the in Fig. 8 embodiment shown, a substructure for a wet cell realized, which allows a simple and error-prone mounting and at the same time creates a substructure with excellent tightness.
