Floor drain assembly

Abstract

An exemplary embodiment providing one or more improvements includes an assembly which fixes and supports a floor drain at the appropriate position before a concrete floor is poured. The assembly is adjustable for floors of varying thickness. The lower or second end of the drain pipe is protected against contamination by wet concrete by a resilient disk. In addition a cavity on the bottom of the floor concentric with the drain pipe is formed. After the concrete floor has hardened and the form removed the resilient disk is removed exposing a clean uncontaminated drain pipe end for connection to a riser pipe.

1 . A floor drain assembly for supporting a floor drain and drain pipe during the pouring of a concrete floor on a form comprising:
 a floor drain body,   a drain pipe having a first and a second end,   the drain pipe attached at the first end to the bottom of the drain body and extending to the form at the second end,   a multiplicity of spacer rods,   the spacer rods attached at a first end to the bottom of the drain body,   a support plate,   the spacer rods attached at a second end to the support plate,   the support plate having a hole through the center of the plate through which the drain pipe extends to the form at the second end of the drain pipe,   the support plate having legs which extend downward from the circumference of the support plate to the form, the legs holding the plate above the form, thereby forming a cavity between the bottom of the support plate and the form,   a disk comprised of resilient material,   the disk inserted into the cavity between the bottom of the support plate and the form,   the disk having a hole through the center of the disk,   the hole through the center of the disk having a diameter slightly less than the outside diameter of the drain pipe, and   the drain pipe force fitted through the hole in the disk at the second end of the drain pipe.   
     
     
         2 . The assembly of  claim 1  wherein the support rods are threaded and are adjustably attached to the support plate. 
     
     
         3 . The assembly of  claim 1  wherein the support plate legs have flanges which extend approximately perpendicular from the legs. 
     
     
         4 . The assembly of  claim 3  wherein the flanges have attachment holes for attachment of the flanges to the form. 
     
     
         5 . The assembly of  claim 1  further comprising holes in the resilient disk, the holes located under the second ends of the spacer rods. 
     
     
         6 . The resilient disk of  claim 1  wherein the disk is comprised of plastic foam, or rubber. 
     
     
         7 . The resilient disk of  claim 1  wherein the disk is comprised of polystyrene or polyurethane foam.
