Definitions

  • This invention relates to a former for supporting a water resistant floor covering, and to a combination of a former and a seamless water resistant floor covering.
  • This type of flooring is especially useful in bathrooms for the disabled, invalid or infirm who are largely unable to negotiate stepping into and out of a bath or shower tray.
  • a shower chair or wheelchair By having a water resistant floor covering laid in the bathroom, a shower chair or wheelchair can simply be placed beneath the shower head, and showering can commence without being overly concerned with splash or spray.
  • the water resistant floor covering is provided with a fall that acts to channel the run-off water to an integral drain formed in the flooring.
  • a problem associated with the installation of a seamless water resistant floor covering occurs when trying to lay or install a former and a purely gravity operated trap. This type of trap generally requires a relatively significant depth of floor to enable installation at the lowest point of the fall of the former.
  • the trap When pouring a concrete floor intended to support a water resistant floor covering, the trap can be reasonably easily incorporated.
  • a significant amount of work has to be performed in order to create a sufficient recess into which the trap can be placed and connected to drain.
  • the thickness of the flooring between the floor on which the water resistant covering is to be placed and the ceiling of the room below can often be a limiting factor.
  • DE3627807 suggests that a plastic gully is cast into a concrete slab.
  • the slab includes a fall leading to the gully.
  • a sealing sheet is positioned over the slab and is fastened in place by concrete screed. Tiles are laid on the sheet and screed up to the grating of the gully.
  • the preformed concrete slab is extremely heavy and cumbersome, being unsuitable for positioning on timber floor joists.
  • the sealing sheet is intended to stop moisture, if passing between the tiles, from permeating into the slab and causing damp problems.
  • US5268096 suggests a pool drain assembly for a swimming pool having a vinyl liner.
  • the assembly includes a drainage receptacle which has an upper edge portion substantially at a level defining the bottom of the swimming pool.
  • the receptacle has a conically shaped seating surface, and the vinyl liner covers the surface.
  • a clamping ring is seated on the seating surface and surrounds a strainer plate which also rests on a lower edge of the seating surface. Again, this arrangement creates a leak path, due to the screws perforating the vinyl liner.
  • the present invention seeks to overcome this problem.
  • former apparatus for supporting a stiff plastics water-resistant floor covering, comprising : a base having a predetermined fall; a trap towards which the fall is directed, the trap having: a sump provided on the base; a shower water inlet recessed into the surface of the base to provide a step to the sump; and a waste water outlet in a side of the sump; a pump attached in-line with the outlet of the sump; and characterised by a clamp element which is provided on the step to the sump to surround an opening thereto and which is disposed on an upper surface of the base, the clamp element having an upturned peripheral edge which lies in parallel or substantially in parallel with a wall of the inlet for clamping the floor covering therebetween and which is mechanically securable to the base by fastening means.
  • the trap further comprises a partitioning element which prevents communication between the shower water inlet and the waste water outlet except at a level below both the inlet and the outlet.
  • the sump may be integrally formed with the base.
  • the sump may be mechanically attached to the base.
  • the waste water outlet may be integrally formed as part of the sump.
  • the waste water outlet may be mechanically attached to the sump.
  • the sump may be made from metal and the waste water outlet may he brazed or welded in place.
  • the trap further comprises a removable cap which covers or substantially covers the sump.
  • At least the base may be formed from glass reinforced plastics material having core reinforcement.
  • at least the base may be formed from resin material.
  • at least the base may be formed from metal.
  • former apparatus in accordance with the first aspect of the present invention in combination with a floor covering material, the floor covering material being cold weldable to produce a seamless and water resistant covering.
  • a former 10 for supporting a seamless water resistant floor covering, such as Altro TM, is shown in Figure 1 .
  • the former 10 can typically be formed from glass reinforced plastics (GRP) material having core reinforcement, resin material or metal, and comprises a base 12 and a trap, generally referenced at 14 and shown in Figures 1 to 6 .
  • GRP glass reinforced plastics
  • the base 12 (shown in Figure 1 ) is formed with a predetermined fall which is directed towards the trap 14.
  • the trap 14 includes a sump 16 which may be formed integrally with ( Figure 1 ), or mechanically attached to ( Figures 2 to 6 ), the base 12, a shower water inlet 18 which is recessed in to the surface of the base 12, and a waste water outlet 20 through which run-off shower water, entering the sump 16 from the shower water inlet 18, can drain.
  • the waste water outlet 20 is disposed in an opening 22 in the side of the sump 16.
  • the waste water outlet 20 may be attachable to the sump 16 (as shown in Figure 1 ), in which case a pipe connector element 24 is typically utilised to securely locate the waste water outlet 20 in the opening 22.
  • the waste water outlet 20 may be formed as part of the sump 16 (as shown in Figures 2 to 6 ), in which case the waste water outlet 20 is dimensioned to be able to receive a discharge pipe (not shown) as an interference fit.
  • the discharge pipe is typically held in place with adhesive.
  • the waste water outlet 20 may be brazed or welded (not shown) into the opening 22.
  • the integral forming and the brazing of the waste water outlet 20 are advantageous in that the depth of the sump 16 can be reduced as the pipe connector element 24 can be dispensed with.
  • a partitioning element 26 typically in the form of a 90° elbow pipe connector, may be attached to a first end of the waste water outlet 20 ( Figure 1 ) and extends into the sump 16 to a position which is above the bottom surface of the sump 16 and below both the shower water inlet 18 and the waste water outlet 20.
  • the partitioning element 26 may also be integrally formed with the waste water outlet 20.
  • a waste water pump (not shown) is attached, typically externally of the sump 16, in-line with the waste water outlet 20.
  • a discharge pipe 28 (shown in Figure 1 ) to drain is fixed to the second end of the waste water outlet 20 and the waste water pump is incorporated into this discharge pipe 28 to aid in the extraction of the run-off shower water from the sump 16.
  • the trap 14 also includes a, typically stainless steel, clamp element 30 which is disposed on the upper surface of the base 12 ( Figure 1 ) and/or the trap 14 ( Figures 2 to 6 ) and which is positioned around the opening to the sump 16.
  • the clamp element 30 typically has an upturned peripheral edge, which lies in parallel or substantially in parallel with the wall of the recessed shower water inlet 18, and is adapted to be mechanically secured to the base 12 by fastening means, such as screws.
  • the trap 14 may further include a removable cap 32 which is disposed over the sump 16. As shown in Figures 1 , the cap 32 may serve to define one edge of the opening to the shower water inlet 18. However, as shown in Figures 2 to 6 , the cap 32 may define the shower water inlet 18.
  • the former 10 In the case of a freshly poured 'green' concrete floor, the former 10, incorporating the preformed fall, is pushed into the wet concrete to a depth where the perimeter edge(s) of the base 12 lies flush with the remaining surface of the concrete. If the trap 14 is separate of the base 12 ( Figures 2 to 6 ), it is mechanically attached to the base 12 typically prior to the base 12 being positioned.
  • a recess of suitable depth can be formed in the floor, and the former 10 can be inserted into position so that the perimeter edge(s) of the base 12 lies flush with the surface of the remaining floor.
  • one or more of the perimeter edges of the base 12 may have to be packed out to bring it flush with the remaining floor surface, and the former 10 may have to include reinforcing elements (not shown) to aid in its structural strength and rigidity.
  • the stiff plastics water resistant material 34 (shown in figure 1 ), typically being for example Altro TM, can then be laid over the floor and the former 10.
  • the material 34 is mechanically clamped by the clamp element 30 at the trap 14 by use of the said fastening means, and cold welded around the edges of the existing floor to create the seamless covering.
  • the waste water pump of the trap 16 operates to extract the run-off shower water, through the waste water outlet 20.
  • the run-off water is extracted typically once the run-off water has filled the sump 16 to a level which is above the opening to the partitioning element 26.
  • the run-off shower water is extracted directly through the waste water outlet 20, typically when it reaches a level which is above the opening of the waste water outlet 20.
  • the activation for the waste water pump may be manual and/or automatic.
  • the pump is fitted with a non-return valve to prevent odours backing up through the waste water outlet 20 and the operation of the pump is linked to the operation of the shower head (not shown), mounted as part of a shower unit installed above the former 10.
  • the shower head not shown
  • a preformed unit having a reduced depth can be directly incorporated with a former when creating a water resistant floor surface having a predetermined fall to drain.
