Abstract

See full text

A trench pan and grate assembly generally rectangular in shape, having downwardly ramped transition bottom walls and an integrally-formed but removable strainer plate, terminating in a round pipe receiving fitting that is, through use of a bushing, able to accommodate the common different types of commercially-available plastic plumbing pipe of a given nominal size, and thus be connected to an underlying sloped main drainage pipe. The separate grate member is installed and fastened down, via threaded fasteners, to the trench pan to complete the assembly. This heavy duty grate is formed using gas-assist molding procedures with fractional-melt material (melt number<1.0). Individual assemblies can be formed end-to-end into an elongate trench drain system, with each assembly containing no standing effluent, and connected to different drainage pipes if desired. Assemblies can be solvent welded to drainage piping and thus require nothing to position and hold while the adjacent concrete is being cast.
