Industrial noise abatement enclosure

An industrial noise abatement enclosure having opposed walls comprising an open framework mountable upon a floor surface and a series of elongated acoustical panels of rectangular cross section arranged side by side loosely and removably mounted upon said framework defining the walls and roof of said enclosure;

• said framework including a plurality of spaced upright corner posts;
• a pair of right angularly related connectors at the top and bottom of each post, with the connectors between an adjacent pair of posts being aligned laterally and longitudinally respectively;
• a plurality of pairs of vertically spaced coplaner top and bottom tubes, with one pair of tubes for each wall of said enclosure, with the respective ends of said tubes snugly telescoped over said connectors, respectively for interlock with said corner posts;
• an elongated upturned bottom channel having a base mounted on and secured to each top tube along its length, with the top and bottom channels for each wall in alignment;
• said channels defining a lateral opening of a predetermined height;
• said panels spanning and at their ends nested and removably interlocked with said top and bottom channels and extending between said corner posts;
• the panels defining the roof being arranged side by side, spanning and resting upon said top tubes respectively;
• the panels defining said side walls resting upon said bottom channels and being of a height greater than said lateral opening and less than the distance between the bases of said channels so as to loosely nest within the top channels;
• each of said panels comprising opposed inner and outer panel faces with inwardly directed opposed side flanges;
• said flanges having reversed turned locking edges;
• a pair of spaced elongated assembly channel strips between said panel faces inwardly of said flanges;
• each strip having inwardly directed opposed lock edges defining an elongated chamber and cooperatively interlocked with said flange lock edges on opposite sides of said panel faces, securing said panel faces together;
• an elongated resilient gasket nested within the chamber of each of said assembly channel strips and including an elongated bead projecting outwardly of said strip and along and outwardly of the sides of each panel;
• an elongated filler of a mineral material, rectangular in cross section and nested between said panel faces;
• said inner panel face being perforated;
• and top and bottom channels overlying the ends of said panel faces;
• said wall panels being individually liftable within the corresponding top channel to facilitate outward removal of the lower ends of each panel from the corresponding bottom channel;
• a resilient gasket strip upon said floor surface underlying the bottom tubes of said framework;
• and additional resilient gasket strips mounted within the bottom channels, yieldably supporting said wall panels;
• inwardly directed angle strips secured to the interior of each of said top tubes along the length thereof and below the tops of said tubes;
• a resilient gasket strip mounted upon said angle strips supportably underlying said roof panels.
