The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

A fire-stopping material in a panel for an interior building wall is provided. The fire-stopping material includes a resilient, porous material at least partially impregnated with an intumescent agent.

A joint-sealing element for sealing building-structure joints is described, especially for sealing against sound and/or smoke and if necessary against fire. In particular, a joint-sealing element for sealing on a building construction and/or on a building structure is described, especially for sealing a joint between a first building part and a second building part, with a carrier element and a sealing profile disposed on this carrier element, wherein the disposed sealing profile has a predetermined geometry.

Furthermore, a sealing arrangement as well as a method for sealing building-structure joints is described, especially for sealing against sound and/or smoke and if necessary against fire, with such a joint-sealing element.

A head of wall assembly includes a compressible component positioned within a deflection gap between an upper edge of the wallboard and a ceiling or other horizontal structural element. The compressible component includes an intumescent strip in contact with the ceiling or the upper edge of the wallboard. The compressible component held in place by a double-sided tape attached with the header track, the ceiling, or the upper edge of the wallboard. The double-sided tape can partially cover one side of the compressible component.

A fire barrier insert for placement within a framed out membrane penetration in a fire barrier wall is constructed of a central back member of a high-temperature drywall board and an attached flexible intumescent mat. The central back board is configured for placement against a drywall panel of similar configuration within the framed out membrane penetration. The flexible intumescent mat consists of separate panels, each attached to the central back board for extending along the frame members and to the outer edge of the framed out membrane penetration. A fixture cabinet is placed within the framed out membrane penetration after installation of the fire barrier insert.

A fire-rated reveal piece and wall assemblies or other assemblies that incorporate the fire-rated reveal piece, in which the reveal piece can include an intumescent or other fire-resistant material strip. The reveal can be attached adjacent to a corner, flange or leg of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the reveal piece.

A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre formed rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod' s ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

System for assisting in reducing the spread of fire between adjacent rooms in a building proximate to the ceiling thereof includes an elongated header track, at least one elongated filler constructed at least partially of compressible or elastic material and at least one fire-blocker constructed at least partially of fire retarding material.

The invention provides a fire-stopping product, an insulated building façade comprising a fire-stopping product, and a method of making a fire-stopping product. The fire-stopping product comprises a resilient, porous material at least partially impregnated with an intumescent agent and held in compression by a releasable restraint. When exposed to hot gases from a fire, the restraint yields to release the resilient, porous material in an initial expansion, thereby exposing the intumescent agent to the hot gases and allowing rapid intumescence to occur. When implemented in a ventilated building façade, the fire-stopping product is able to close an air gap in a short amount of time.

A fire protection element contains a layered body for sealing passage openings in components, such as building components, through which lines are guided. A method can be used for producing the fire protection element and the fire protection element can be used for sealing passage openings and/or joints in components against fire and flue gases.
