Floor drainage systems in locations using a relatively large amount of water are usually covered with expanded metal gratings which easily become blocked and do not allow sufficient support for relatively heavy vehicular traffic to pass thereover. The present device utilizes a culvert section having spaced apart upper angle members and a sheetmetal culvert depending there below, the depth of which gradually increases from one end to the other. Location tabs extend from the sides of the culvert along the length thereof and these are all spaced the same distance downwardly from the upper angle members so that the sections are all readily supported upon pegs placed along the trench at the same depth from the surface. Concrete may then be poured around and under the culvert and the floor surface finished flush with the upper surface of the angle members so that only an elongated slot is seen when the installation is completed.
A culvert assembly for use in a trench type floor drain system comprising in combination a pair of longitudinally extending upper members in spaced and parallel relationship defining an elongated, unobstructed drainage slot therebetween, a culvert component secured to and depending from said members, said culvert component including a longitudinally extending through-like base portion below the drainage slot and sloping with respect to the upper members from a first end of the assembly to a second end thereof, and side flange portions converging upwardly from respective side edges of said through-like base portion and being secured along upper edges thereof to respective ones of said upper members, depth registration and support snchor members extending outwardly from the sides of said culvert component along the length thereof, said depth registration and support anchor members all being equidistantly spaced downwardly from said upper members.
A culvert section for a culvert assembly in a trench type floor drain system, said section comprising in combination a pair of spaced and parallel, longitudinally extending upper right angled members defining an unobstructed drain slot therebetween and a culvert component secured to and depending from said members with the slot operatively communicating with the interior of said culvert component, said culvert component including a longitudinally extending trough-like base portion below the slot and sloping from a first end of the section to a second end with respect to the upper members and side flange portions converging upwardly from the respective longitudinal side edges of said base portion, the upper edges of said side flange portions being secured to respective ones of the right angled members.
