Description

The invention is directed to a sanitary cell with according to the preamble of claim 1 and to a method for its production.

In the simplest case, sanitary cells are shower cubicles, but in the case of a modern prefabricated construction, this usually means a room which, in addition to a shower, e.g. also includes a toilet and a hand basin. Such sanitary cells play a role in particular where a bathroom is not bricked up in a conventional manner, but where a large number of such sanitary cells must be accommodated in a single building with load-bearing walls and pillars.

Such sanitary cells should be quick and easy to install with as little special knowledge as possible after creating the load-bearing structure with a high degree of prefabrication, while on the other hand the cost of prefabrication should be kept within limits.

Sanitary cells are already known, which are built on a cast floor tray made of polyester. Such molded plastic parts have the disadvantage that their production is associated with very considerable molding costs, with regard to this, the variability is also low, since a separate, new mold would have to be produced in each case when there are dimensional changes or adjustments. In addition, such plastic trays are known to be relatively sensitive to mechanical damage, so that they can only be installed in a relatively late construction phase.

From US-A-20 59 614 a generic sanitary cell is known, which is composed of a floor pan and connected to this side walls. The floor pan comprises a frame made of a moisture-resistant metal profile, which in cross-section in the area of its lower edge is perpendicular to the base plate that is vertical in the position of use, i.e. horizontally extending approach. This forms a solid contact surface on the floor and at the same time enables mounting holes to be made to create a screw connection with the floor. Such a floor frame can be easily manufactured in all dimensions in conventional metal construction technology, so that building on one and the same basic construction, sanitary cells for completely different building objects or within the same object for different space requirements can be produced.

The side walls in the sanitary cell according to US-A-20 59 614 are screwed to one another via inclined projections on the metal profile or on the lower edge of the side wall. In this context, this sanitary cell is in need of improvement in terms of its stability, ease of installation and tightness.

From US-A-22 41 860 a sanitary cell with a floor pan is also known, in which the metal collecting tray has an L-shaped projection on its upper edge, which is used to fasten the side walls via an intermediate frame. The sanitary cell according to US-A-22 41 860 on the one hand has the disadvantages of sanitary cells with a cast floor tray made of polyester, as explained above, on the other hand the connection between the side walls and the edge of the one-piece floor tray is very complex, inter alia because of the additional intermediate frame.

The present invention is therefore based on the object of developing a sanitary cell of the generic type so that its assembly is simplified and in particular a pre-assembly of the floor pan with the frame is possible in the shell construction phase of the building accommodating the sanitary cell.

This object is achieved by the features specified in the characterizing part of patent claim 1. Accordingly, on the basis of the insensitive, stable metal profile, which can be achieved through the specified profile has a high degree of inherent stability, the floor pan of the sanitary cell is already pre-assembled in the shell construction phase of a building due to its associated robustness and then the wall elements are finally assembled. Due to the construction according to the invention, these only need to be hung with their clasps in the vertical L-legs of the metal profile. The latter thus forms an ideal hanging option for this bracket attachment. This advantageously also avoids the introduction of bores into the cladding elements from the visible side.

The flat contact of the cladding elements on the outside of the vertical L-leg creates an overlap that ensures forced drainage of the water running off from the cladding elements into the floor pan. This reliably prevents water from escaping. At the same time, the cladding elements lie flat and thus defined.

An aluminum profile or a galvanized steel profile is preferably used as the metal profile.

Vertical U-profile struts are particularly advantageously attached to the inside of the vertical L-leg. The attachment can by a screw connection with the U-bottom of the struts or by riveting or the like. respectively. The horizontal L-leg serves as a stop or support surface for the vertical U-profile struts, it being provided that the depth of the horizontal L-leg corresponds to the depth of the U-legs of the U-profile struts, so that they are flush with the outside complete with the vertical base plate of the floor pan.

A sealing tape, which is expediently designed to be self-adhesive, is advantageously inserted between the vertical L-legs of the floor pan and the cladding elements. In this way, a lock for water vapor is also realized.

The vertical struts are conveniently connected by horizontal U-profile struts, whereby not only is a stiffening of the upwardly extending construction achieved, but also to which sanitary items can be attached directly.

The vertical and / or horizontal U-profile struts have on each U-leg extending outwards, parallel to the U-bottom approaches. These strip-like approaches can be used in the vertical struts, for example, in order to establish a connection to an adjacent, immediately adjacent construction in a simple manner. In the case of the horizontal struts, these approaches can also be used to hang in clasps of the cladding elements.

In a preferred embodiment, the floor pan and the frame are made in one piece by deep drawing from sheet steel and subsequent coating, in particular enamelling. In principle, a coating with plastic or the like could also be used. to introduce. This configuration makes it possible to achieve a completely homogeneous and dense floor construction with absolute tightness, so that manufacturer's warranty problems are reduced to a minimum. To improve structure-borne noise insulation and thermal insulation, such floor trays are backfilled with polyurethane or polystyrene foam.

According to this concept according to the invention, all the advantages are achieved which are already known in the conventional large-scale manufacture of floor trays, i.e. in particular also the connection of several such tubs to one another via connecting elements. In terms of manufacturing technology, this only requires a minor modification of the tools which are already conventionally used.

The method according to the invention is intended to enable a sanitary cell to be constructed in a light, damage-proof manner and in accordance with the individual requirements. According to this, it is provided that the metal profile is screwed to the on-site raw ceiling is that floor insulation, a screed and a surface coating such as tiles, plastic coverings and the like. Are applied, and that only after the completion of the shell construction, the vertical struts are attached and the cladding elements are attached.

This procedure has the significant advantage that, taking advantage of the robustness of the floor pan according to the invention, extensive preparation of the fastening options for the vertical structure in the shell construction phase takes place, the then possibly scratch-sensitive cladding elements only after the shell shell phase has been completed, i.e. if sand, mortar or other aggressive agents are no longer processed, be applied.

In Fig. 1, a sanitary cell 1 is shown with a floor pan 1a, which comprises a frame 2 made of a metal profile 3.

A plurality of vertical struts 4 and a door element 5 are fastened to the frame 2. At the upper end, the vertical struts 4 are connected to one another via horizontal struts 6. A roof panel 7 serves to cover and stiffen the entire cell. The side walls are formed by cladding elements 8.

The frame 2 has no closed bottom, but the bottom is constructed in a conventional manner.

This is particularly clear from Fig. 2, where one can see in the exploded view there that in the frame 2 a floor insulation 9, a screed 10 and a surface coating 11 - in the embodiment in the form of tiles - are introduced. A drain opening in the floor is indicated at 12.

The frame 2 is made of galvanized sheet steel in the embodiment. It comprises a base plate 13, which is vertical in the installed state. At its lower edge 14 there is a first extension 15, which extends at a right angle from it, that is to say extends horizontally. At the upper edge 16 there is an L-profile 17 with a first horizontal leg 18 and a second vertical leg 19, the horizontal leg 18 in the same direction as the approach 15 and extends parallel to this.

The approach 15 forms a good footprint and also allows (see Fig. 5) the insertion of fastening screws 2o, with which the frame 2 can be screwed to the bare ceiling.

The floor insulation 9, the screed 10 and the surface coating 11 are applied in a conventional manner such that at least the surface coating 11, but preferably also the insulation 9, is pulled up laterally up to the lower edge of the first L-leg 18 (cf. in particular FIG. 5). , The thickness of these layers is dimensioned such that it is equal to or less than the free width of the leg 18.

As is shown in particular in FIG. 3, after the frame 2 has been attached to the bare ceiling and after the insulation 9, the screed 10 and the surface coating 11 have been introduced (in FIG. 5, this is carried out as a tile covering and on the right as a PVC covering), ie after the final completion of the shell construction on the frame 2 vertical struts 21 attached by screws 22 '. The vertical struts 21 are designed as a U-profile, with the outwardly directed projections 24 adjoining the U-legs 22 running parallel to the U-floor 23. Horizontal U-profile struts 26 can be screwed onto these attachments 24 by screws 25, which also have outwardly extending attachments 27, ie essentially the same profile have like the vertical struts. Sanitary objects can be attached to these vertical struts, as is not shown in detail. At the same time, these horizontal struts 26 also stiffen the entire construction.

The cladding elements 8 have so-called agraffes 29 on their rear side 28, which are fastened by means of screws 30 and are secured against rotation via protruding lugs 30 'and beads 31 on the rear wall 28. In order to fasten the cladding elements 8, projecting retaining lugs 32 of the clips 29 overlap the vertical L-leg 19 of the metal profile 3 of the floor frame 2 or a lug 27 of the horizontal struts 26.

The cladding elements 8 overlap the vertical L-leg 19 of the metal profile 3 on the outside, a sealing strip 33 being applied in the overlap area in order to prevent steam from penetrating into the area behind the cladding elements 8.

The vertical longitudinal edges 34 of the cladding elements 8 are connected to one another via a profile 35 and lateral grooves 36. The profile 35 is screwed onto the outside of the U-bottom 23 of the vertical struts 21 by means of screws 37. An elastic sealing profile 38 is used to produce a seamless connection (see FIG. 5).

5 shows two sanitary cells 1 standing against each other, ie the adjacent frames 2 lie directly against one another via the base plates 13 and the lugs 24 of the vertical struts likewise lie directly against one another and enable a connection to be established by means of screws or the like. The representation of a sanitary cell with a section through the wall closure looks similar.

In the variant shown in FIG. 4, the basic structure is the same, but a U-profile 38 is inserted between the two frames 2 or between their base plates 13, and horizontal struts 40 extend from the U-base 23 via screws 39 U-floor 23 of the vertical profiles 21 of adjacent sanitary cells 1 extend. In this way, an intermediate space for receiving installation pipes 41, 42 and, if necessary, for receiving a sound and heat seal is created.

6 shows in a sectional view the case in which a sanitary cell 1 is installed on a fixed room wall 43. In this case, the lugs 24 can be fastened to the wall by means of fastening screws 44, so that overall a very stable connection is obtained.

FIG. 7 shows a corresponding sectional view of the situation according to FIG. 5 with two sanitary cells placed directly next to one another. In this case, screws 45 and nuts 46 of the adjoining lugs 24 can be screwed together.
