Abstract:
A firestop collar means with improved mounting means positioned adjacent a cavity defined between a structural panel having an aperture therein extending from the first side to the second side thereof and a generally cylindrical penetrating member extending through the aperture, said firestop collar means comprising:A. a collar member positioned adjacent the first side of the structural panel surrounding the cylindrical penetrating member adjacent the cavity defined between the cylindrical penetrating member and the structural panel to facilitate sealing of the aperture to inhibit movement of fire, heat and smoke therethrough; B. an anchoring means comprising: (1) a first leg member attached to said collar member and extending through the cavity of the structural panel to the second side thereof, said first leg member defining a first collar end attached to the collar member adjacent the first side of the structural panel and a first protruding end spatially disposed from said first collar end and extending through the cavity to the second side of the structural panel; (2) second leg member attached to said collar member at a position spatially disposed from said first leg member, said second leg member extending through the cavity of the structural panel to the second side thereof, said second leg member defining a second collar end attached to the collar member adjacent the first side of the structural panel and a second protruding end spatially disposed from said second collar end and extending through the cavity to the second side of the structural panel; and (3) an arcuate member secured to said first protruding end of said first leg member and to said second protruding end of said second leg member and extending through an arcuate shaped curve therebetween, said arcuate member being formed of a flexibly resilient material to allow selective modification of the radius of curvature thereof to facilitate insertion of said anchoring means through the cavity for engagement of the arcuate member with the second side of the structural panel to facilitate retaining of said collar member adjacent the cavity on the first side of the structural member.
