Roof drain receiver

Abstract

A roof drain receiver for a site cast construction is provided comprising: a hollow main body partially buried in a wall of the construction near its bottom portion during the site casting and having one or more top inlets for receiving a number of vertical drain pipes extending interior of the construction wall to channel drain water collected from the top of the construction, and a large rectangular spout extending from the main body to an exterior side of the construction wall for emitting the channeled water off the wall. The main body has an anchoring flange for securing the same to an inner surface of the construction, a replaceable faceplate having a large rectangular opening in the center and a check door pivotally connected to the faceplate for allowing water down flowing while it normally blocks a forced entry of foreign objects into the main body.

         4 . The roof drain receiver of  claim 1 , wherein the rectangular spout of the main body is 6 inches long for penetration through a 6 inch depth of the construction wall during the site casting to channel drain water collected from the top of the construction away from the wall through the check door pivotally connected to the spout. 
     
     
         5 . A roof drain receiver of  claim 1 , wherein the drain receiver is generally made of cast bronze. 
     
     
         6 . A roof drain receiver of  claim 1 , wherein the drain pipes are supported by a unistrut pipe fixture including a channel interlocking bracket horizontally attached to the wall and a pair of clamp halves slidably held in the bracket to clamp each received pipe cooperatively and wherein the pipe sleeves are located at a predetermined distance from the wall. 
     
     
         7 . A roof drain receiver of  claim 6 , wherein the pipe sleeve has a distance of ⅞″ from the wall to position the pipe fixture therebetween. 
     
     
         8 . A roof drain receiver for a stick built building construction comprising:
 a hollow main body engaged in a wall of the construction near a wall bottom portion attached between studs of a building wall;   top pipe sleeves for receiving a number of vertical drain pipes extending interior of the building wall to channel drain water collected from the top of the building, a large rectangular spout extending from the main body to an exterior side of the building wall for emitting the channeled water off the wall and a check door pivotally connected to the spout for allowing water down flowing while it normally blocks a forced entry of foreign objects into the main body.   
     
     
         9 . The roof drain receiver of  claim 8 , wherein the main body further comprises a rectangular spout with a protruded end face partially recessed; an anchoring flange circumferentially extending in a plain perpendicular to the spout for securing the main body to an inner surface of the construction; and a faceplate having a large rectangular opening in the center, a plurality of bolt holes for accepting threaded fasteners driven though the faceplate to the protruded face of the spout, a generally U-shaped rear flange for mating internally with the recess of the protruded face, and a generally U-shaped front flange slanted downwardly for emitting drain water away from the construction. 
     
     
         10 . The roof drain receiver of  claim 8 , wherein the roof drain receiver is made of molded plastic and the faceplate is replaceable for matching color to the exterior of the wall as well as for maintenance. 
     
     
         11 . A roof drain receiver for a wall comprising:
 a hollow main receiver body having;   at least one top pipe sleeve extending upward from the hollow main receiver body,   wherein the top pipe sleeve is adapted to receive a member of vertical drain pipes to channel drain water collected from the top of the building;   a large rectangular spout extending from the main body to an exterior side of the building wall, wherein the main receiver body forms an approximately 90° bend for directing channeled water away from the wall;   a check door pivotally connected to a flange; and   a generally U-shaped rear flange for mating internally with the recess of a protruded face, and a generally U-shaped front flange slanted downwardly for directing drain water away from the construction.   
     
     
         12 . The roof drain receiver of  claim 11 , wherein the roof drain receiver is made of molded plastic and the faceplate is replaceable for matching color to the exterior of the wall as well as for maintenance. 
     
     
         13 . The roof drain receiver of  claim 11 , wherein the check door has a pair of pivot arms that connect to hinge portions mounted on a faceplate, wherein the faceplate is mounted to a main flange formed on the hollow main receiver body, wherein the hinge portions it into hinge portion notches formed on the hollow main receiver body. 
     
     
         14 . The roof drain receiver of  claim 13 , further comprising a gasket fitting between an outlet frame and a faceplate, wherein the gasket is basically rectangular and has bolt holes for receiving bolts and forming a water tight seal between the outlet frame and the faceplate. 
     
     
         15 . The roof drain receiver of  claim 14 , wherein the roof drain receiver is made of molded plastic and the faceplate is replaceable for matching color to the exterior of the wall as well as for maintenance.
