Abstract
A fire rated component wall system includes first and second compartmentalized units joined by top and bottom steel cover plates. The first and second units are constructed from interlocking steel panels with sheets of fire retardant material defining a compartment therebetween. The first and second units are mated along the sides formed from the fire retardant material to provide a structural wall system with exterior steel panels and interior layers of fire retardant material. The steel panels are interlocked by an insert member from the end of one panel received and held within a slot of a second panel. An interior weld may be applied to the inside of the interlocking panels of the first and second units to provide a tamperproof connection between the steel panels.
