[0001] wet room

[0002] Technical area

[0003] The invention relates to a wet room with at least one wall, which comprises a lining made of a room-side, ceramic inner layer and a wall-side outer layer glued to the inner layer to form a composite body, wherein the composite body forming a self-supporting wall element is fastened in a grid-like manner to a supporting frame.

[0004] State of the art

[0005] The walls of wet rooms are often lined with ceramic tiles. The walls must be extensively prepared before these ceramic tiles can be glued on. To enable simple renovation of such wet rooms, it is known (DE 102017 109 075 A1) to provide large-area wall elements that comprise a building board made of, for example, rigid foam and a tile covering glued to the building board. To ensure that these prefabricated wall elements can be installed tightly, sealing tape is glued along the outlines of the wall elements drawn on the wall to be renovated and adhesive beads are applied on both sides of the butt joint between the wall elements. This allows the self-watertight wall elements to be bonded to the wall using the adhesive beads, without having to remove the existing wall cladding.These known wall elements therefore require a load-bearing cell wall to which the wall elements can be glued with the interposition of edge sealing tapes. In order to avoid having to glue ceramic linings onto appropriately prepared wall surfaces, it is also known (DE 4341100 A1, EP 3978700 A1, US 5816005 A, US 9297167 B1) to use prefabricated wall elements which have a self-supporting, possibly multi-layered base plate to which ceramic tiles are glued. These wall elements can be attached in various ways at locations distributed in a grid-like manner on supporting structures. However, the self-supporting base plates of these wall elements require additional materials. Furthermore, the wall elements are considerably thicker than conventional coverings made of ceramic tiles.

[0006] To improve the strength of ceramic tiles, it is also known (CN 202577743 U) to construct the tiles in three layers, with two ceramic outer layers bonded together by an aluminum intermediate layer. The aluminum intermediate layer can also be honeycomb-shaped (CN 202577835 U) to achieve better sound insulation properties. With such an aluminum intermediate layer, higher strength values ​​of the tile bodies can be achieved compared to single-layer ceramic tiles of comparable thickness, despite comparatively thin ceramic outer layers. Furthermore, appropriately prepared wall surfaces are required for adhesive attachment of these ceramic tiles.

[0007] Description of the invention

[0008] The invention is based on the object of designing a wet room with a ceramic lining in such a way that no complex preparation of walls is required for the construction of the wet room in order to be able to stick on the ceramic tile covering.

[0009] Starting with a wet room of the type described above, the invention achieves the stated object by connecting the ceramic inner layer to the likewise ceramic outer layer by a vapor-tight intermediate layer to form a self-supporting wall element. By providing a composite body made of two ceramic layers, a self-supporting wall element is obtained that is, on the one hand, sufficiently flexible to absorb bending stresses, for example, during transport or installation, without risk of breakage, and, on the other hand, sufficiently rigid to be attached to a supporting structure in a load-bearing manner. By connecting the two ceramic layers via a vapor-tight intermediate layer, a bending behavior is achieved for the composite body that essentially corresponds to the bending behavior of the individual layers, while the strength is determined by the composite effect.

[0010] Therefore, no prepared, flat wall surface is required to install the wall elements. A supporting frame is sufficient, to which the wall elements are attached in a grid pattern, preferably by gluing. The supporting frame, which advantageously forms a frame following the contours of the wall elements with struts between the frame legs that stiffen the frames, can be placed in front of a wall or used as a load-bearing wall structure.

[0011] The tightness of such a wet room wall is ensured by the vapor-tight intermediate layer between the ceramic inner and outer layers of the wall elements, with the advantage that this vapor-tight intermediate layer, usually a sealing foil, runs protected in the neutral zone of the composite body. Furthermore, by setting one of the two ceramic layers back from the other layer, an edge seam covered by the vapor-tight intermediate layer can be created to tightly connect the wall element.

[0012] To ensure a tight connection between the wall elements that abut in the corner area between two walls, these wall elements can have an outer layer that is offset inwards relative to the inner layer along the corner area. If the abutting corner edges of the inner layers that protrude beyond the outer layers and are provided with the vapor-tight intermediate layer are covered by an external angle, a vapor-tight connection between the wall elements is also created in the corner area. In a similar way, a vapor-tight connection of the wall elements to the wet room floor can be achieved if the wall element that protrudes from a floor has an outer layer in the floor area that is offset relative to the inner layer, so that the floor edge of the wall element that protrudes beyond the outer layer towards the floor and is covered by the vapor-tight intermediate layer can cover a floor leg.

[0013] The wall elements preferably each form the ceramic lining of a wet room wall, which ensures simple installation conditions. However, several large-area wall elements can also be offset to form the ceramic lining of a wet room wall. In this case, advantageous construction conditions arise if one of two adjoining wall elements has an edge section of the inner layer that protrudes beyond the outer layer, and with this protruding edge section of the inner layer, covered by the vapor-tight intermediate layer, overlaps in a seam-like manner an edge section of the outer layer of the adjoining wall element that protrudes beyond the inner layer.

[0014] The opposing protruding edge strips of the inner and outer layers overlap each other when the wall elements are installed, with the vapor-tight intermediate layer in between, thus ensuring a vapor-tight connection between the individual wall elements and thus, in turn, a vapor-tight ceramic lining of the wet room wall.

[0021] Ways to implement the invention

[0022] A wet cell according to the invention has at least one cell wall 2 projecting from a floor 1 with a ceramic lining, which is preferably formed by a prefabricated wall element 3 extending over the entire wall surface. This wall element 3 comprises a ceramic inner layer 4 facing the cell space and a ceramic outer layer 5 facing away from the cell space, which is connected to the inner layer 4 by a vapor-tight intermediate layer 6 to form a self-supporting, rigid composite body, which is fastened, preferably by gluing, to a supporting frame 7 forming a load-bearing wall structure. As shown in Fig.As indicated in Figure 1, the supporting structure 7 forms a frame following the outline of the wall element 3, which is stiffened by struts provided between the frame legs to support not only the wall element 3 but also the wet room fixtures in a load-bearing manner, for which connection openings are provided in the correspondingly prefabricated wall element 3. Since no full-surface bonding of the wall element 3 is required, fastening at individual fastening points distributed in a grid-like manner across the wall surface is sufficient. Accordingly, a grid-like supporting structure 7 is sufficient for fastening a wall element 3.

[0023] To construct a wet room, all that is required is a supporting frame 7 rising from the floor 1, to which the ready-to-install wall elements 3 of the wet room are attached. This eliminates the need for flat wall surfaces for fully gluing the ceramic tiles, which would otherwise be required. To ensure a vapor-tight connection in the corner area between two cell walls 2, the wall elements 3 can have an outer layer 5 offset inwards along the corner area compared to the inner layer 4, so that, as shown in Figs. 4 and 5, a corner edge 8 of the inner layer is created which projects continuously over the height of the wall element 3 and is covered by the vapor-tight intermediate layer 6. The corner area formed by the projecting corner edges 8 when two wall elements 3 forming a cell corner are offset can, as shown in Fig.2 can be covered by an external angle 9, whereby the tight, fold-like connection of the wall elements 3 in the corner area is achieved by an external angle 9 with low manufacturing effort.

[0024] In a similar way, a tight connection of the wall elements 3 to the floor 1 can be structurally prepared by the wall elements 3 also having an outer layer 5 in the floor area that is offset inwards compared to the inner layer 4, so that the inner layer 4 forms a floor edge 10 that protrudes from the outer layer 5 according to Fig. 4 and is covered by the vapor-tight intermediate layer 6. With the help of a floor leg 11 that forms a raised floor edge and that, according to Fig. 3, is overlapped in a fold-like manner by the floor edge 10 of the inner layer 4 of the wall elements 3 when the wall elements 3 are offset, the tight connection of the wall elements 3 to the floor 1 of the wet room is thus ensured via the vapor-tight intermediate layer 6.

[0025] In special cases, it may be advantageous to divide the ceramic lining of a cell wall 2 into several large-area wall elements, which, however, must be connected to one another in a vapor-tight manner. Such a division of the wall surface into several wall elements 3a, 3b, 3c is indicated, for example, in Fig. 6. The arrangement is such that one of the adjoining wall elements 3a, 3b, 3c has an edge section 12a, 12b of the inner layer 4a, 4b that protrudes beyond the outer layer 5a, 5b, and with this protruding edge section 12a, 12b overlaps an edge section 13b, 13c of the outer layer 5b, 5c of the adjacent wall element 3b, 3c that protrudes beyond the inner layer 4b, 4c.Since the wall element 3b with the protruding, height-adjusting edge section 13b of the outer layer 5b thus overlaps the protruding edge section 12a of the inner layer 4a of the wall element 3a in a fold-like manner and, analogously, the floor-parallel edge sections 12a, 12b of the inner layers 4a, 4b of the wall elements 3a, 3b are overlapped by the protruding edge section 13c of the outer layer 5c of the wall element 3c, each with the vapor-tight intermediate layer 6 interposed, an overall vapor-tight ceramic lining of the cell wall 2 is obtained despite the structure comprising several wall elements 3a, 3b, 3c.
