An improved head-of-wall structure for an interior, nonload-bearing building wall is provided in which a pair of elongated angle strips are employed to connect the upper ends of to the upright metal studs fluted metal decking above in a seismic and fire-resistant manner. A plurality of uniformly spaced pop-up tabs are defined in the horizontal legs of the angle strips directly beneath the open flutes or channels of the metal decking above. Insulation supports are located beneath the ceiling flutes to span the distance between the angle strips. The insulation supports are connected to the vertical legs of the angle strips to form flat, horizontal platforms directly beneath the portions of the flutes that cross the line of studs. Batts of fire-proofing insulation are located atop the insulation supports and are held in position by bending up the pop-up tabs from their original horizontal disposition into a generally vertical orientation.

[ I claim:] [1.] In a building interior head-of-wall structure for a nonload-bearing wall in which a plurality of vertical metal wall studs are arranged in a straight horizontal line and project upwardly and terminate beneath a ceiling formed of a metal deck having an exposed undersurface that defines a plurality of mutually parallel, concave downwardly facing flutes, the improvement comprising a pair of sheet metal angle strips that join said wall studs to said ceiling deck,wherein said angle strips each include a vertical leg secured to said metal wall studs and a horizontal leg having an outer edge remote from said vertical leg, and said horizontal leg is scored toward said vertical leg at longitudinally spaced intervals along said outer edge to define a plurality of pop-up tabs that are bent to project upwardly into and block said flutes on both sides of said line of metal wall studs.
