Abstract: A sealing gasket for use attached preferably to the topmost edge of gypsum board when used as construction wallboard. The gasket includes a support leg section capable of being mounted in engagement with preferably the uppermost edge of the gypsum board. The gasket includes a sealing leg extending outwardly from said leg section which includes an intumescent component to facilitate sealing between the edge of the gypsum board and the wall structure above. In one embodiment the sealing leg includes an intumescent impregnated paper material covered with a structurally enhancing layer. An adhesive layer can be included to attach the gasket to the gypsum wallboard. The sealing leg is in this embodiment is planar and will extend upwardly and inwardly over the upper edge of the gypsum board at an obtuse angle with respect to the support leg for sealing thereabove in the head-of-wall area.

Abstract: A construction for effectively fireproof sealing of the gap between the floor of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration utilizing an interior panel module design. The insulating system includes a supplemental insulation belt positioned beneath the safing insulation and attached to the interior panel of a curtain wall construction to maintain sealing of the safing slot during exposure to fire and heat which can cause the interior panel to deform from heat warping to an extent beyond the capability of standard safing insulation for expanding in order to maintain a proper seal extending across the safing slot.

Abstract: An angular flange for reinforcing and firestopping in the annulus between a structural panel such as a wall, ceiling or floor and a duct extending therethrough. The prefabricated angular flange includes a first flange leg to be secured to the duct and a second flange leg with a sealing member preferably of flexibly resilient foam which could be intumescent attached to a surface of the second leg such that when the first flange leg is secured to the duct the second flange leg can be urged against the structural panel extending therearound with the sealing member positioned between the structural panel and the second flange leg and sealing the annulus.

Abstract: A firestopping device which is held between the flange of water closet flange assembly and the floor surrounding the opening containing the drain pipe which includes a securement section positioned therebetween for being held in place and an intumescent section extending radially inwardly therefrom to a position above the vertical drain pipe opening to facilitate intumescent expansion thereinto responsive to the exposure of heat.

Abstract: An angular flange for reinforcing and firestopping in the annulus between a structural panel such as a wall, ceiling or floor and a duct extending therethrough. The prefabricated angular flange includes a primary angular flange leg to be secured to the duct and a secondary angular flange leg approximately perpendicularly oriented relative thereto. Each flange includes a sealing member of flexible intumescent paper positionable therealong to facilitate firestopping therebetween. The sealing member preferably including two panels at an obtuse angle with respect to one another and being flexible to become approximately perpendicular with respect to one another responsive to securement of the angular flange to the duct and the surrounding structural panel. One or more uniquely designed corner brackets can be included for mounting the adjacently positioned angular flanges with respect to one another selectively.

Abstract: A collar positionable about a panel penetrating member for sealing therearound and particularly for firestopping therearound which prevents the flow of smoke and may include an intumescent component for expansion during exposure to heat. A collar assembly is usable with members penetrating various types of panels including walls, ceilings and floors. The sealing member of the assembly includes frangible zones with removable sections which are mated to the construction of the mounting strap. The mounting strap includes engagement prongs and multiple engagement apertures securable with respect to one another in various relative positions for use with respect to panel penetrating members of various standardized sizes. The engagement of the prongs in various apertures is mated with the frangible zones on the sealing member for effective sealing around panel penetrating members of standardized sizes such as 3 inch, 3½ inch, 4 inch and 4½ inch and others.

Abstract: A multi-part mounting assembly for securing a plurality of individual pathway conduits relative to one another extending through a wall panel between adjacently positioned wall studs including two support members extending parallel to one another and defining therebetween a pathway conduit zone for receiving the individual conduits along with end members for providing sealing at the outermost edges and one or more partitioning means securable at a plurality of discrete positions within slots defined in the support members and being securable with respect to the support members and including set screws for safely holding pathway conduits in position extending therethrough.

Abstract: The present invention provides a firestop collar with an improved apparatus and method for mounting thereof with respect to a annular cavity formed in a wall or floor around a pipe or other cylindrical member protruding therethrough. The collar member preferably is positioned adjacent to the surface surrounding the protruding member and contains preferably intumescent material therein which is responsive to heat in order to expand and fill the aperture extending through the wall or panel during heat, fire or smoke conditions. The anchoring device for the present invention is adapted to hold the collar in abutment with the structural wall in position surrounding the penetrating conduit and it includes two leg members and an arcuate member. The arcuate member extends between the leg members and is made of a flexibly resilient material and has a radius of curvature less than that of the protruding conduit.
