Abstract: 819,401. Partition walls. AETNA STEEL PRODUCTS CORPORATION. June 21, 1957 [Aug. 8, 1956], No. 19673/57. Class 20(4) A partition wall includes a base comprising a longitudinal metal member 70 adapted to be secured to a floor F and having sides 78 upstanding from a bottom portion 74, and longitudinally extending, vertical, base plates 72 having provision for resiliently being urged into overlapping engagement with the lower part of the wall and provided with integral spring clip portions 86 at the inner sides thereof which engage both surfaces of the sides 78, of the base member. As shown, the panel units 22 comprise sheet-metal, side panels 32 each bent backwardly at the longitudinal edges thereof to provide transversely extending portions 36 formed with flanges 38, the panels being secured together by interlocked, H-shaped members 44 welded to the portions 36; the space between the panels is filled with sound-insulating material 54 such as rock wool. The upper and lower walls of the units are formed by channel members 56 the webs of which are notched to provide a passageway for wires or cables. To vertically align the panel units a pair of brackets 81 for each unit is provided, the brackets having tapped openings 90 for reception of bolts 92 and apertures 94 to allow the passage of wires or cables through the end walls 88 thereof. The side walls of the brackets are formed with shoulders 100 which are passed through notches in the inturned portions 62 of the flanges 60 of the channels 58 and urged along the latter until engaged behind the portions 62. By rotation of the bolts, the lower ends of which are received in apertures 104 in plates 102, the panels are raised or lowered as required. Channel members 106 are inserted in the joints 108 between pairs of adjacent panel units, and members 110, having opposed flanges 112 which overlie the sides of the panel units, are provided with U-shaped seatings 114 for reception of a sound barrier B of gypsum board mounted over the partition wall and extending to the structural ceiling 35; a dropped ceiling C is supported by angle members 212. An end filler 24, Fig. 6, is provided between a masonry wall W and the adjacent panel unit, the filler comprising a channel member 116 secured to the wall and having formed integrally therewith clips 128 which receive panels 120 having portions 146 complementary to clips 140 mounted in cutouts 138 in a post 118 of channel section and secured by screw-threaded elements 130 to the end wall of the panel unit. Corner posts supported on brackets and comprising a pair of complementary rightangle panels are constructed in the same way as the units and are secured to the latter by members 44. For the door 180, vertical sections 184, 186, Fig. 17, are interconnected at the upper ends thereof by a transom section mounting a transom panel unit 28, and are held in position at floor level by clips 206. In a modified joint 108A, Fig. 13, each panel unit 22a has an end wall portion 164 terminating in a reflexed tongue 169 and an inwardly offset crimp 170, so that when a pair of panel units are joined to each other, the crimp 170 of one unit abuts the portion 168 of the other unit and each tongue extends between the opposing tongue and portion 168.
