A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.
Firestop block and thermal barrier system for fluted metal decks
InactiveUS20090223159A1Improve installation securityImprove convenienceWallsBuilding repairsFirestopRefractory
The invention provides methods, systems and devices for installing thermal barriers in openings or gaps in or between structures such as walls, ceilings and floors. At least one firestop block is positioned in the holes or gaps formed by the wall and a fluted metal deck of the ceiling or floor. The walls can be gypsum walls, which may have a metal track at the top or bottom, or could be block walls made of concrete or similar material. The firestop blocks are made of fire resistant material such as hydratable cement or intumescent materials. A flexible or flowable firestop material that is operative to cure or harden, such as elastomeric sealant or silicone, or hydratable cementitious slurry, is introduced into the space between the firestop block and the hole or gap, as a sealant or filler.

Fire transmission prevention system
A fire transmission prevention system (10) for use in a drainage system (100) to prevent the transmission of smoke and fire through the drainage system. The system is intended to be used in drainage systems in multi-story structures. The system includes a firestop (16), couplings (14, 26 and 30) and an air vent (42). The firestop prevents fire and smoke from moving through the inner passageways (44D) of the pipes (12, 24, 28 and 72) of a drainage system by blocking the inner passageway of the pipes with a fire resistant plug (20). The couplings are mounted in the floor (102) of the structure and are constructed and secured in the floor such as to prevent fire and smoke from passing around the couplings between the couplings and the floor. The air vent is provided in a vent pipe (40) of the system above a trap (38 or 78) of the system. The vent acts to prevent ambient air and thus, oxygen from entering the inner passageway of the pipes of a system when positive pressure, such as that caused by high temperature and fire, is present in the inner passageway of the pipes.
