Abstract

1301831 Modifying acoustic properties ARMSTRONG COOK CO 2 Jan 1970 [30 Oct 1968] 51553/68 Heading G5X [Also in Divisions E1 and F4] Vertical panels 8 forming a suspended box structure are fixed back to back at their lower edge in channel section members 11 which span the structure or channel section struts 12 engaging between adjacent members 11. A similar framing structure at the top edge of the panels is clamped to the lower structure and to the panels by means of a screw-threaded rod 21 with a nut at both ends or a stop 22 at one end and a nut 23 at the other. The supporting elements at junctions of panels may comprise cruciform channelled sections similarly clamped. The box structure may be staggered and the panel surfaces may be designed for acoustical control.
