Drop-in fire stop assembly for concrete floor pipes
The patent US12044345B2 describes a drop-in fire stop assembly designed for installation in a cylindrical passage through a hardened concrete slab. This assembly features a fire ring composed of two rotating portions that can transition between open and closed positions, allowing for the definition of a circular fire ring opening. The assembly includes a cylindrical cage with curved sidewall portions that encircle the fire ring opening and are hinged to facilitate rotation. Additionally, the assembly incorporates an intumescent ring positioned within the sidewall portions, which expands in response to heat, enhancing fire resistance. The design also includes retaining and support arms that help maintain the structure's integrity and limit movement of the inner components.
Further enhancements to the assembly include inner and outer smoke rings, which are strategically placed to improve smoke containment during a fire event. The inner smoke ring is located between the intumescent ring and the fire ring, while the outer smoke ring is positioned outside the cage, adjacent to the fire ring. The assembly is adaptable for use with tubes passing through the passage, ensuring that it can accommodate various installations while maintaining its fire-stopping capabilities. The claims outline specific structural features, such as the arrangement of retaining arms, support arms, and the configuration of the smoke rings, all contributing to the assembly's effectiveness in preventing the spread of fire and smoke through openings in concrete structures.
