Description

The invention relates to a support system for baths or shower trays, the are provided with a peripheral rim in particular, with at least one mounting rail that can be fastened on the wall and between Tub and floor with support elements.

When installing bathtubs or shower trays there is generally the problem that through the resulting connections with the Structural bridges for structure-borne noise are not only created are undesirable but often also prevent existing ones Regulations and recognized rules of technology regarding the Structure-borne noise insulation is taken into account.

Even if it should be possible, the required structure-borne noise insulation on the bottom side due to the floating screed below located thermal and impact sound insulation in the required manner To ensure, the problem remains that over the tub edges and in particular also referring to the retaining wall to be attached in front of the tub. Apron very annoying sound bridges arise.

In principle, it would be possible to achieve the required sound insulation or structure-borne sound insulation by means of targeted, but also complex measures when installing such tubs. However, such special assemblies cannot be implemented on normal construction sites, where work usually has to be carried out under time and cost pressure and with less qualified personnel.
From DE 41 26 383 A1 a mounting element for baths and shower trays is known which has the shape of a U-shaped mounting rail with a shorter and a longer leg and whose base located between these two legs is provided with water drainage openings. This mounting element is attached to the wall with the longer leg, and a sound decoupling band of U-shaped cross section can be slid onto the shorter leg, which is overlapped by the tub rim after the tub has been installed. The tub itself is also supported via support feet and at least one bricked-up wall, an essentially rigid material strip being arranged as a sound decoupling element between the free end of the bricked-up wall and the tub rim assigned to it, which on the one hand has a smooth underside for resting on the brickwork and on the other hand, has a profile design on the opposite side that corresponds to the underside of the tub in the area of the upper tub rim. Due to the support feet provided on both sides of the center of the tub, there is already a structurally perfect tub support, ie there would be a static overestimation if the wall-side support rail also had a supporting function.
With the configuration shown and described in DE 41 26 383 A1, it is to be achieved that, on the one hand, the leakage water which passes through the joints between the tub edge and the room wall cannot lead to an impairment of the wall and, on the other hand, there is the possibility of a tub once used without destroying the Remove the tiling or the tub-carrying parts.

The object of the invention is a carrier system of the beginning mentioned type to create that extremely easy to handle, in particular appropriate and positionally accurate without exceptional specialist knowledge is mountable and thereby ensures that disturbing structure-borne noise transmissions in the building can be reliably excluded, whereby finally an appropriate and existing provisions and approved installation of the relevant technology enables tub installation shall be.

You can see the sectional view of the bathtub 1, the a carrier system according to the invention on the one hand via a Support rail 2 on the wall 3 and on the other hand on the Support rail 2 opposite support wall 4 is supported. In addition, there is between the screed 5 and the tub rim and / or the tub floor 6 three support members 7a, 7b are provided, of which in Fig. 1 only two is visible. It is also an embodiment conceivable where only two or more than three support members 7a, 7b are provided.

The tub 1 has a circumferential, bent outward Tub edge 8, over which the tub 1 on the support wall 4, supported on the mounting rail 2 and on the support members 7b is.

If there is no retaining wall in an alternative application should be available (so-called dry construction method, see also Fig. 14), the tub rim 8 can only be on one or more Support organs are supported, the structure of which in 1 can correspond to the supporting members 7b shown, however, the length of the screed 5 - tub edge 8 distance have to be adjusted.

The mounting rail 2 has a Z-shaped profile and is, for example by means of a screw connection on the wall 3 appropriate. The mounting rail 2 attached to the wall 3 forms together with the wall 3 a U-shaped cross section, open-top receptacle for a sound decoupling layer 9, which is adapted in its profile to the mounting rail and on which the tub rim 8 is supported.

The wall 3 is provided with a tiling 10, which ends above the tub rim 8.

Between the tiling 10 and the tub rim 8 or between the wall 3 and the tub rim 8 is a sound decoupling element with an L-shaped cross section 11 provided, which an additional Sound decoupling of the tub 1 against the wall 3 and the Tiling 10 causes and also a constant and uniform Distance between tub edge 8 and tiling 10 or between the tub edge 8 and wall 3.

The supporting wall 4 also provided with a tiling 12 is in its upper area with a sound decoupling Profile element 13 occupied, which is tiled in its shape Retaining wall 2 is adapted and ensures that a direct Contact between tub edge 8 or tub 1 and retaining wall 4 or tiling 12 is avoided.

The support members 7a, 7b have at least one sound decoupling Insulating element, which ensures that between the Tub floor 6 and the screed 5 or between the tub edge 8 and the screed 5 no structure-borne noise bridges can arise. A possible form of training a support member 7a, 7b is shown for example in Figs. 13a and 13b.

In a preferred embodiment of the invention the support members on the side facing away from the mounting rail 2 the tub or the tub bottom 6 arranged. In this way is on the side of the tray bottom facing the mounting rail 2 6 sufficient space for the provision of pipelines 14 created. The support organs are each approximately the same distance from the wall 3 in the longitudinal direction of the Tub arranged offset to each other.

Fig. 1c essentially corresponds to Fig. 1b, there are here only those arranged in the corner areas of the tub 1 Support organs 7b can be seen completely. These support members 7b are variable in length and therefore the distance between Tray edge 8 and screed 5 adaptable.

2a to 2c show different situations during installation a bathtub in a bathroom. In Fig. 2a, the tub 1 is only with one of its long sides on a wall 15. With this one-sided wall connection is the tub 1 on the wall 15 by means of an inventive Carrier rail held.

The other three sides of the tub 1 are on below it support walls erected.

2b shows a two-sided wall connection of the tub 1 the walls 15 and 16, here the two the walls 15 and 16 opposite sides of the tub 1 each of supporting walls be worn.

2c shows a three-sided wall connection of the tub 1 the walls 15, 16 and 17, the tub 1 only on the the wall 16 opposite side of a support wall will be carried.

In an installation situation according to FIGS. 2b and 2c, the Tub on at least one of the walls 15, 16 or 15, 16, 17 be held by means of a mounting rail, however it is also possible that the tub 1 on several of the walls 15, 16th and 15, 16, 17 held by means of a mounting rail is.

The number of mounting rails used in an installation situation 2b and 2c is, for example, of the used Tub material dependent, whereby for plastic tubs As a rule, all-round edge support is required is also a support for steel or cast tubs on only one retaining wall and an opposite one Wall can suffice.

When using dry planking (Fig. 14) instead of one Walling in is necessary, a tub with its tub rim to be supported on the floor and at the edge using at least two support elements. Furthermore, the tub floor is over at least one Support element on the ground side. Possible embodiments suitable support members are in connection with Fig. 13a and 13b. In addition, for a sound-decoupling wall mounting be taken care of, for example, with a corresponding trained anchors (DE 43 24 133.6, EP 94 110 896.1) or a similar device is feasible.

The mounting rail 2 is designed in accordance with FIG. 1 and creates one together with the wall 3 in this way Essentially open receptacle for a cross section U-shaped sound decoupling layer 18, which in turn is a has an upwardly open receptacle for the tub rim 8.

For example, is suitable for the production of the mounting rail 2 galvanized steel, aluminum and the like, preferably make sure that the material used is moisture resistant.

The open at the top and suitable for receiving the tub rim 8 Recess of the sound decoupling layer 18 is included a load distribution layer 19, which in particular consists of Hard plastic, aluminum or the like can be made can. The load distribution layer 19 is preferably in the Glued recess of the sound decoupling layer 18 or pressed in. Through the load distribution layer 19, the tub load or the total load of tub, water and user be evenly distributed over the length of the mounting rail 2.

The load distribution layer 19 is not required if a material is used as the sound decoupling layer 18 that has both good sound decoupling properties has as well as mechanically resilient without too much deformation results. In this regard, it offers itself for example the use of a polyurethane elastomer on.

Between the wall 3 and the area of the Trough edge 8, a sound decoupling element 20 is provided, which has an L-shaped cross section, wherein one leg of this sound decoupling element 20 horizontally above the tub rim 8 and the other leg extends vertically between the tub edge 8 and wall 3.

The sound decoupling element 20 performs two tasks: On the one hand, the sound decoupling element 20 causes one effective sound isolation between the tub edge 8 and wall 3. It is by the provision of the sound decoupling element 20 impossible for the tub to slip, for example, that the tub edge 8 comes to rest directly on the wall 3 and in this way a sound bridge is created.

On the other hand, the sound decoupling element ensures which has a constant cross-section over its entire length has that between the tub rim 8 and the wall 3 an even distance is maintained and also a constant distance above the tub edge 8 the wall 3 attached tiling 21 to the tub edge 8 guaranteed is.
