Definitions

  • a partition wall comprising a plurality of aligned modular panels.
  • Each panel includes a pair of wallboards disposed in spaced substantially parallel relation and channel-shaped spacer members interposed between the wall-boards along two opposite edges thereof.
  • the wallboards and the spacer members define an air space.
  • Each spacer member includes a web bridging the air space between the wallboards and a pair of substantially parallel flanges extending toward, but terminating short of, the opposite edges of the wallboards.
  • Fasteners penetrate the wallboards and the flanges of the spacer members.
  • Each fastener has an end extending inwardly of the spacer members.
  • Contiguous edges of the wallboards of the aligned panels are positioned in abutting relationship and form joints between the aligned wallboards.
  • the spacer members contiguous to said joints form a cavity.
  • the flanges of the spacer members are spaced apart and defining a gap on opposite sides of the cavity.
  • a fire-resistant spline member is disposed in and bridges the cavity.
  • the opposite lateral sides of the spline member are seated in the gaps on the opposite sides of the cavity and overlays the joints between the abutting edges of the wallboards.
  • Fire-resistant clearance members are secured to the opposite sides of the spline memher, and the clearance members are of less lateral extent that the spline member, thereby clearing the ends of the fasteners.
