PURPOSE: A drain pipe system for on-floor piping is provided to install on-floor pipe in an existing wash room without a design change by simplifying the drain pipe system. CONSTITUTION: A drain pipe system for on-floor piping comprises a drainpipe system main body of cylinder shape and an upper base frame(260). The drainpipe system main body is installed on the foundation floor concrete layer of a wash room. The top of the drainpipe system main body is opened. At least more than one water collection pipe fastening portion and a drainpipe fastening portion are formed on the side surface of the drainpipe system main body. The upper base frame arranged on the top of the drainpipe system main body moves to any location before the upper base frame is fixed by a finish material. The upper base frame is manufactured in a plane shape having diameter greater than that of the drainpipe system main body diameter. An upper base plate fastening portion(240) divided by a strip type projection(243) for coupling the upper base frame is formed on the upper surface of the upper base frame. An offensive odor backflow preventer fastening portion(254) is formed on the center of the upper base frame. |
