Abstract: A safety device is provided for combatting "wind load" on ceiling constructions in both upward and downward directions, particularly in ceilings of the type wherein flanged panels are supported from tee shaped panel carriers which are suspended from the ceiling. The safety device comprises an inverted U-shaped clip or wire which fits over the panel carrier so that the central portion of the clip bears against the horizontal upper surface of the associated panel carrier and the legs of the clip engage and support the corners of four panels which meet a point beneath the central portion of the clip. The free ends of the clip preferably include bent-up portions which engage in holes provided in the corresponding flanges of the panels.

Abstract: A fastener strip is provided which is utilized in a building wall construction comprising sheets of foamed plastic such as polystyrene affixed to a concrete wall and covered by panels of gypsum or the like. The fastener strips are positioned over the foamed sheeting and assist in nailing the sheeting to the wall. The cover panels are screwed to the fastener strips. The fastener strips comprises a relatively thin, generally planar strip of material which includes a plurality of reinforcing ribs therein to provide strengthening of the strip and a series of teeth cut out of the body of the strip for engaging the foamed sheeting so as to hold the strip in the appropriate position for nailing. The teeth are formed simultaneously with rolling of the fastener strip from a roll-forming machine.
