Shower floor formers

Abstract

A former 1 is provided for creating a sloping profile for waste-water run off below a waterproof floor covering of a shower area. The former is made of a moulded plastics material, such as from material known as Bulk (or Dough) Moulding Compound or material known as Sheet Moulding Compound, and has sloping surfaces 3 converging to a predefined drainage hole 4 shaped to accept and retain a waste connection and which provides means for engagement of at least one clamping or retaining device for a waterproof floor covering, wherein the perimeter of the former surrounding the hole 4 has a stepped profile to provide at least one annular flange 8 outside the plane of the former within which fastening means are locatable.

1 . A former for creating a sloping profile for waste-water run off below a waterproof floor covering of a shower area, wherein the former is made of a moulded plastics material and has sloping surfaces converging to a predefined drainage hole shaped to accept and retain a waste connection and which provides means for engagement of at least one clamping or retaining device for a waterproof floor covering, the perimeter of the former surrounding the drainage hole having a stepped profile to provide at least one annular flange outside the plane of the former within which fastening means are locatable. 
     
     
         2 . A former as claimed in  claim 1  wherein the former is provided with at least a double stepped profile to provide two annular flanges, the upper flange having preformed recesses or holes for location of the fastening means. 
     
     
         3 . A wet floor shower waste comprising a former as claimed in  claim 1  wherein the annular flange supports a flange extending around a pipe coupling for connection to a waste below the former. 
     
     
         4 . A wet floor shower waste as claimed in  claim 3  wherein the former is provided with at least a double stepped profile to provide two annular flanges, an upper flange having preformed recesses or holes, wherein a waterproof flexible floor covering is received between the former and a clamping element, the clamping element being supported on the upper flange and retained in place by means of fasteners provided in the preformed recesses or holes. 
     
     
         5 . A wet floor shower waste comprising a former as claimed in claimed  1 , the former surrounding the drainage hole having at least a double stepped profile to provide two annular flanges, an upper flange having preformed recesses or holes, wherein a tiling adaptor is supported by the upper flange of the former and retained in place by means of a clamping element secured by fastening means provided through the clamping element and tiling adaptor and received in the preformed recesses or holes of the flange, and wherein the other said annular flange supports a flange extending around a pipe coupling for connection to a waste below the former. 
     
     
         6 . A wet floor shower waste as claimed in  claim 5  wherein the tile adaptor comprises a body having an in use upper surface with a perimeter edge for lying flush or substantially flush with an in use upper surface of adjacent or abutting tiles, an aperture formed in the body for waste water to pass into the wet floor waste and means for engaging the body of the tiling adaptor with the wet floor waste. 
     
     
         7 . A former as claimed in  claim 1 , wherein a plurality of holes or shaped recesses to accept fixings to hold the former in the required location are distributed around the periphery of said former. 
     
     
         8 . A former as claimed in  claim 1 , wherein the lower surface of the former has a plurality of individual or crossed reinforcing ribs. 
     
     
         9 . A kit of parts for a wet floor shower waste comprising a former as claimed in  claim 1 , a wet floor covering material, a clamping element and a pipe coupling for connection to a waste water outlet.
