Self-Supporting Shower Floor Element Comprising A Film For Sealing The Floor And Walls

Abstract

The aim of the invention is to provide a shower floor element and a shower floor construction, which permit an extremely simple, cost-effective production, in particular in situ and/or a more reliable sealing system in relation to prior art. To achieve this, a waterproof film is applied to the upper face of a support element consisting of a hard expanded plastic with a relatively high density of approximately 100 g per cubic decimetre or more and is sealed to said support element. This enables the pre-fabrication of a shower floor element, so that during the installation in situ a tile covering or other covering can be directly applied to the film. If a suitable material is selected, said film can also be welded to the support element. Preferred connection methods are bonding or welding. Depending on the material, a shrinking or deep drawing process can also optionally be used, or a negative pressure can be produced between the film and the support element, causing the two materials to adhere to one another.

1 . A shower floor element comprising a two-dimensional support element of rigid foam, further comprising a water-impermeable film is applied to the upper side of the support element, in particular to the rigid foam. 
   
   
       2 . The shower floor element as claimed in  claim 1 , wherein the film is adhesively attached to the upper side of the support element over the full surface area. 
   
   
       3 . The shower floor element as claimed in  claim 1 , wherein the film is welded to the upper side of the support element. 
   
   
       4 . The shower floor element as claimed in  claim 1 , wherein the film is thermoformed and welded onto the upper side of the support element without any folds. 
   
   
       5 . The shower floor element as claimed in  claim 1 , wherein the film is connected in a waterproof manner to a drain flange part in the shower floor element. 
   
   
       6 . The shower floor element as claimed in  claim 1 , wherein the film has a lateral overhang beyond the outer edges of the upper side of the support element (that is so extensive that in the installed state of the shower floor element it forms a floor/wall transition. 
   
   
       7 . The shower floor element as claimed in  claim 1 , wherein the film has a lateral overhang beyond the outer edges of the upper side of the support element that is so extensive that in the installed state of the shower floor element it forms a shower floor/room floor transition. 
   
   
       8 . The shower floor element as claimed in  claim 6 , characterized in that the bearing surfaces of the lateral overhang are coated with a layer of adhesive in a self-adhesive manner. 
   
   
       9 . The shower floor element as claimed in  claim 1 , wherein the film is formed such that it is rough on one or both sides and/or laminated or provided on one or both sides with an adhesive layer, in particular of a fiber-like and/or nonwoven-like material. 
   
   
       10 . The shower floor element as claimed in  claim 1 , wherein the support element (is formed in one piece and/or in the form of a panel. 
   
   
       11 . The shower floor element as claimed in  claim 1 , further comprising the rigid foam is formed to withstand such loads as to allow it to support a covering of tiles without any reinforcement or supporting layer. 
   
   
       12 . The shower floor element as claimed in  claim 1 , wherein the rigid foam has a density of at least approximately 0.09 kg/dm3, in particular at least 0.1 kg/dm3. 
   
   
       13 . The shower floor element as claimed in  claim 1 , wherein it has a ready-to-use floor surface ( 9 ). 
   
   
       14 . A shower floor construction with a covering of tiles, which cover over a shower floor element comprising a support element of rigid foam, characterized in that the shower floor element is formed as claimed in  claim 1  and/or in that the support element exclusively forms the supporting layer for the tiles, or no supporting layer is arranged between the supporting element and the tiles. 
   
   
       15 . The shower floor construction as claimed in  claim 14 , wherein the film forms the only sealing layer between the support element (and the rigid foam on the tiles. 
   
   
       16 . The shower floor construction as claimed in  claim 14 , wherein the tiles are adhesively bonded directly to the film by means of a tile adhesive. 
   
   
       17 . The shower floor construction as claimed in  claim 14 , wherein arranged between the support element and a laterally adjoining substructure is a sealing compound, in particular a sealing compound that cures rapidly and/or with the exclusion of air, which is covered over by the covering. 
   
   
       18 . The shower floor as claimed in  claim 14 , wherein the support element is adhesively bonded onto a substructure. 
   
   
       19 . The shower floor construction as claimed in  claim 14 , wherein the support element rests on a supporting frame with height-adjustable mounting feet, a rigid foam part being used as the support element, in which recesses for receiving fastening means of the mounting feet are provided.
