Substructure element for placement beneath a shower base element

Abstract

The invention relates to a substructure element ( 8 ) for placement beneath a shower base element ( 2 ), wherein the substructure element ( 8 ) and shower base element ( 2 ) are provided with a drainage opening ( 3 ) for installing a drain pan ( 4 ), and the substructure element ( 8 ), which occupies the entire volume between the underside of the shower base element ( 2 ) and the mounting substrate, comprises at least one panel ( 7; 9 ) made of foamed plastic material, which is provided with an opening that is adapted to the peripheral design of at least one drain pan and is provided with a structured lumen that extends through the thickness of the substructure element and adjoins the opening.

1 . A substructure element ( 8 ) for placement beneath a shower base element ( 2 ), wherein the substructure element ( 8 ) and shower base element ( 2 ) are each provided with a drainage opening ( 3 ) for installing a drain pan ( 4 ), and the substructure element ( 8 ), which occupies the entire volume between the underside of the shower base element ( 2 ) and the mounting substrate ( 10 ), comprises at least one panel ( 7 ;  9 ) made of foamed plastic material, which is provided with an opening ( 3 ′;  3 ″) that is adapted to the peripheral design of at least one drain pan and is provided with a structured lumen ( 30 ) that extends through the thickness of the substructure element and adjoins the opening ( 3 ′;  3 ″). 
     
     
         2 . The substructure element according to  claim 1 , characterized in that the element comprises at least two substantially congruent panels ( 7 ;  9 ), each of which is provided with openings ( 3 ′;  3 ″) that are adapted to the peripheral design of drain pans ( 4 ), and are provided with a divided, structured lumen ( 30 ′;  30 ″) that extends through the thickness of the substructure element ( 8 ) and fits to the opening ( 3 ′;  3 ″), wherein, in the installed state, the contours and openings of the panels ( 7 ;  9 ) of the substructure element ( 8 ) and of the shower base element ( 2 ) coincide with each other. 
     
     
         3 . The substructure element according to  claim 2 , characterized in that the at least two panels ( 7 ,  9 ) have different construction heights. 
     
     
         4 . The substructure element according to  claim 3 , characterized in that, when at least two panels are present that have different construction heights, the height of the first panel ( 9 ) is 60±5 mm and the height of the second panel ( 7 ) is 30±5 mm. 
     
     
         5 . The substructure element according to  claim 4 , characterized in that the total height of the panels does not exceed 90 mm. 
     
     
         6 . The substructure element according to  claim 2 , characterized in that, in the installed state, the lumen ( 30 ″) of the first panel ( 9 ) accommodates the outer contour of a drain pain, so that it can serve as a sole substructure element. 
     
     
         7 . The substructure element according to  claim 6 , characterized in that the thicknesses of the panels are selected to be 40 mm, 30 mm, and 20 mm when three panels ( 7 ;  9 ) are present. 
     
     
         8 . The substructure element according to  claim 1 , characterized in that the foamed plastic material selected for the substructure element is expanded polystyrene foam (EPS) or extruded polystyrene foam (XPS). 
     
     
         9 . The substructure element according to  claim 1 , characterized in that the foamed plastic material selected for the substructure element is polyurethane foam. 
     
     
         10 . A substructure element according to  claim 1 , characterized in that at least two separate openings ( 3 ;  23 ′+ 23 ″) and corresponding lumina for drain pans are introduced into the substructure element ( 8 ), which in the installed state coincide with drainage openings of different shower base elements and are compatible with the respective drain pans. 
     
     
         11 . A set of components for producing a shower base that can be tiled, comprising a shower base element, a substructure element, which includes at least two panels ( 7 ;  9 ) according to  claim 2 , and a drain pan to be positively fitted into the lumen. 
     
     
         12 . A substructure element according to  claim 6 , characterized in that at least two separate openings ( 3 ;  23 ′+ 23 ″) and corresponding lumina for drain pans are introduced into the substructure element ( 8 ), which in the installed state coincide with drainage openings of different shower base elements and are compatible with the respective drain pans.
