Bottom mounted (anchored) fire barrier systems include UL 2079 and ASTM 1399 tested and certified fire barrier/retainer structures, especially useful for floor/floor, wall/floor, and wall/ wall expansion joint spaces formed by spaced opposing pre-cast concrete building units of 41/2 inches thickness. The use of this system in structures using pre-cast building units provides room for installation of mandated rubber boots into the limited expansion joint space. Each fire barrier has affixed to its outside long edges a metal retainer that is structured for holding the barrier correctly and tightly positioned to the building unit surfaces first for secure and tight anchoring and then for providing support for the barrier to prevent leakage of gas, flame, smoke, and heat during a fire. Providing for ease of installation there is a reusable installation tool, an optional guard unit, male/female connections between barrier sections, and a splice connector butt to connections.
