Abstract
Fire-barriers systems, including pre-assembled intersection and straight-line fire-barriers having either male-coupling ends, female-coupling ends or both types provide for the elimination of on-site cutting and construction for easy, rapid, and safe one-step, drop-in installation and coupling. Both the intersection and straight-line fire-barriers are constructed as single-piece continuous units for use in intersection spaces formed by intersection of expansion-joint-spaces and in straight-line architectural expansion-joint-spaces to prevent migration of gases, flame, and smoke throughout a building. Indirect attachment of the layers to each other and to their solid support brackets provides for no continuous opening throughout the barriers preventing passage of smoke, fire, and gases therethrough. Each style barrier is provided with an optional one-step, one-person, drop-in, reusable, width adjustable installation tool.
