Abstract: An interlocking frame assembly for constructing and supporting a wall system, wherein a plurality of substantially H-shaped support sections are each formed with a pair of flange members extending substantially perpendicularly from a side thereof, with each pair of flange members having a pair of inwardly directed projections and each pair of leg members forming the H-shaped support section also having a pair of inwardly directed projections. A plurality of connecting sections are selectively positionable to engage the inwardly projecting projections of separate support sections to interconnect said support sections in perpendicular or parallel arrangement relative to one another.
