Description

The present invention relates to a floor element for a ready-to-use bath.Ready-made baths are used, for example, in residential construction, in the construction of hotels or other accommodations, in order to produce baths at low cost. Finishing baths are room modules which are manufactured in manufacturing facilities or factories and then supplied to a construction site where the modules are installed in the building to be erected or existing. The modules comprise a floor element, wall elements and optionally also a ceiling element.Depending on the degree of pre-manufacturing in the production facilities or factories, the modules are equipped completely or partially with water, heating and / or electronic installations. It is also possible that the modules are supplied without installation.It is likewise possible for the walls and / or the floor to be supplied in a tile-covered manner or to be supplied provided with another ready-to-foot floor or wall covering.As a rule, the washbasin, bidets and / or toilet bowl is already mounted. However, it can also be mounted at a later point in time.In contrast, shower trays or shower trays are first built up in an elevated manner on the existing floor covering in the modules produced today. Or, recesses are provided in the floor elements, into which recesses the shower trays or shower trays are installed in a conventional manner.This necessitates additional work in an otherwise completely prefabricated ready bath, which work could be done more efficiently in the production facility or the factory without a handman having to put hand on a construction site or in ongoing production.Unfortunately, hitherto, for ready-made baths with shower trays or shower trays installed at the factory, no solution has been found which is convincing in all respects:From document DE 20 2007 005 783 U1 a so-called shower floor element is known, which can be installed in a floor and subsequently covered with a floor covering. An suggestion for a solution for an efficient and durable installation of a shower tray or shower tray is not provided by the document DE 20 2007 005 783 U1.The document DE 20 2009 008 775 U1 relates to a shower floor unit which can likewise be installed in a floor. Unlike the shower floor element known from document DE 20 2007 005 783 U1, a finished floor made of a cured liquid is provided, which is not covered with a further floor covering. An suggestion for a solution for an efficient and durable installation of a shower tray or shower tray is also not provided by the document DE 20 2009 008 775 U1.Document DE 1853597 U relates to a component for receiving built-in shower trays. This component is a square block adapted to the outline of a shower tray shape known per se and provided with a cavity adapted to the tray. The component can be anchored on a floor and laid.Exposed side surfaces of the component can be clad. The shower tray can be installed in the component and is held therein by its weight. Document DE 1853597 U also does not provide any suggestion for a solution for an efficient and durable installation of a shower tray or shower tray.In particular, the documents also do not provide any excitations for the connection of the required seal in the trough connection regions to adjacent installations.The invention starts here.The invention is based on the problem of proposing a floor element for a ready-to-use bath, in which the shower tray or shower tray is installed in the factory in a manner which is as level as possible, without a barrier and watertight.This problem is solved according to the invention in that the floor element has a concrete plate into which the shower tray or shower tray is inserted, wherein a planar textile structure, an epoxy resin, in particular a two-component epoxy resin or a plastic dispersion mixture with or without sand as a component is arranged between the shower tray or shower tray and the concrete plate, which is bonded on the one hand to the shower tray or shower tray and on the other hand has a firm connection to the concrete plate. The planar textile structure, the epoxy resin or the plastic dispersion mixture serves as an adhesion promoter between the underside of the shower tray or shower tray and the concrete panel, which conforms completely or at least predominantly to the underside of the shower tray or shower tray. This creates a system without hollow spaces under the trough, which prevents drum effects and thus also serves for sound protection.The planar textile structure can be fabric-reinforced. Preferably, the planar textile structure is water impermeable. It is possible for the planar textile structure to be diffusible.The planar textile structure can have a thickness of about 0.5 mm. A surface weight of the structure can be 250 to 350 g / m 2, preferably about 305 g / m 2. It can have a tear strength of >300 N / 50 mm, in particular of >400 N / 50 mm.Advantageously, the planar textile structure is glued to an underside of the shower tray or shower tray, in particular over its entire surface, using an adhesive. The adhesive may be a commercially available adhesive.A floor element according to the invention can be produced by an inventive method with the following steps:producing a mold in the dimensions of the floor element to be produced,inserting the shower tray or shower tray, wherein an upper side of the shower tray or shower tray lies on a bottom of the mold,adhering the underside of the shower tray or shower tray to the planar textile structure,filling concrete into the mold, the underside of the shower tray or shower tray, which is bonded to the planar textile structure, being covered with the concrete,curing of the concrete; anddemolding the floor element.It is possible, after the shower tray or shower tray has been inserted, to connect waste water lines to the shower tray or shower tray and to install them in the mold. Also, after the mould is manufactured and before concrete is poured into the mould, empty pipes can be laid in the mould, for example for an electric or heating installation. It is also possible that lines of a floor heating system are laid in the mold before concrete is introduced.The invention will be described with reference to the following description of an exemplary embodiment with reference to the accompanying drawing. In this figure, the following is shown in schematic representation: FIG. 1 shows a section through a floor element according to the invention and a mold in which the floor element is arranged at the end of the production process.In Fig. 1, reference numeral 2 denotes a mold (concrete form) having a bottom and side walls. A shower tray 12 is placed upside down into this mould 2. The upper side of the shower tray 12 rests on the bottom of the mould 2, and a planar textile structure 13 is glued onto the upwardly facing lower side of the shower tray 12. This structure 13 serves as a bonding agent between the shower tray 12 and the concrete filled into the mould up to its edge.A waste water line 14 is connected to an outlet of the shower tray 12 and is cast into the concrete surrounded by a sound insulation, not shown.The concrete or the concrete slab 11 produced therefrom nestles on all sides against the shower tray 12. The planar textile structure 13 acting as adhesion promoter between the shower tray 12 and the concrete slab 11 produces a permanently durable connection between the shower tray 12 and the concrete slab 11, which connection does not become detached even when the floor element 1 is transported and vibrations connected therewith. It is thus possible to level floor elements with shower trays or shower trays and produce them in a watertight manner already at the factory, which can be done more efficiently than installation on a construction site.
