Abstract

Refinements introduced into a rectangular cross-section ductwork for ventilation and other applications, consisting of adjacent ductwork sections to be interconnected by a completely surrounding band or strip attached to the adjacent ends of each pair of adjacent ductwork sections, characterized in that Each section comprises four separate, generally flat, side wall elements (10) having interlocking shapes (12, 13) along with their longitudinal side edges, adapted to removably fix the side wall elements together with one another, juxtaposed by the edges, and the side wall elements extending in perpendicular planes to each other along each edge, each side wall element having a strap portion (11) along one of its transverse side edges, the strap portions having conformations intertwined (20, 21) next to their d the ends respectively, each adapted to detachably interlock with an end shaping of girdle portion adjacent to the adjacent end of the girdle portion of the adjacent side wall element when the side wall elements are removably attached to one another, juxtaposed by the edges along their longitudinal side edges, as mentioned.
