A B S T R A C T A frame structure has a plurality of transverse beams arranged to extend between a pair of main beams The main beams have generally vertical central portions, against which the ends of the transverse beams abut. The transverse beams are generally inverted U-shaped, and are formed with hooks on the lower edges of the legs which engage slots extending vertically in the central portion of the main beam. The transverse beams further have grooves extending transversely through their webs for receiving projections of the main beams, thereby enabling the transverse beams to be snapped into position against the main beam by a rotating movement.
