Abstract: A supporting structure for furniture has at least one upright and at least one bracket which can be attached to the upright. The upright has a cross-section in the form of lobes extending longitudinally along the upright, each pair of adjacent lobes defining a corresponding longitudinal seat.

Abstract: A partition wall, preferably, a fire retardant partition wall, has posts and crossbars consisting of steel hollow profiles with grooves on the broad and narrow sides. A narrow groove on the board side serves to receive elastic couplings attaching the crossbars to the posts. A wide groove extending the full width of each wide side receives a sealing strip baring on panels which are suspended from studs traversing the posts. Between the panels on opposite sides of the structure, a thermally insulating nonflammable material is received and a labyrinth seal can be provided between the panels and the posts and crossbars and between the packing material and these hollow profiles.
