Abstract
A system for sealing a joint gap between structural substrate panels such as walls, ceiling and floors making use of a sealing member including a mounting section fixedly secured to one of the surfaces and a covering member extending outwardly therefrom into contact with the other substrate member. These walls, ceilings and floors can be movable relative to one another and thus the present invention provides a mechanism for sealing the joint gap between the substrates while allowing them to move with respect to one another. This is achieved by fixedly securing the sealing member to one of the substrates and urging it into abutting engagement with respect to the other substrate.
Claims18
A method for sealing a joint gap defined between a first structural substrate and a second structural substrate which are independently movable relative to one another, said method comprising:
- A. providing of a sealing member having a mounting section and a flexibly resilient covering section defined thereon;
- B. placing the flexibly resilient covering section into abutment with the second structural substrate without permanent securement therebetween;
- C. compressing the flexibly resilient covering section by deforming thereof at least partially against the abutting second structural substrate member to facilitate sealing engagement therebetween without permanent securement therebetween;
- D. fixedly and permanently securing the mounting section of the sealing member in direct abutting contact with respect to the first structural substrate while maintaining the flexibly resilient covering section deformed and biased into abutment against the second structural substrate member without permanent securement therebetween for sealing between the first structural substrate and the second structural substrate at all times including during independent relative movement therebetween;
- E. applying of a scrim material layer across the outwardly facing surface of the mounting section and the coveting section of the sealing member for reinforcing thereof, said applying of a scrim material layer including applying an extension section extending beyond the end of the covering section to extend outwardly therefrom over at least a portion of the second structural substrate;
- and
- F. applying of a layer of sealing composition over the sealing member and the scrim member to facilitate sealing against the adjacently positioned first and second structural substrate members, said applying of a layer of sealing composition being performed with a sealing composition that includes an intumescent component to facilitate sealing of the gap between the first and second structural substrates responsive to conditions of extreme heat.
A joint sealing means positionable extending over a joint gap defined between a first structural substrate and a second structural substrate which are independently movable and adjacently positioned, said joint sealing means including
- A. a sealing member being flexible and preformed into a predetermined shape, said sealing member including:
- (1) a mounting section positional in abutment with respect to the first structural substrate and adapted to be attached permanently with respect thereto for sealing engagement therewith;
- (2) a covering section made of flexibly resilient material and attached with respect to said mounting section and extending outwardly therefrom away from the first structural substrate and toward the second structural substrate and into abutting contact therewith without being permanently secured thereto, said mounting section of said sealing member and said covering section thereof being a single integrally formed unit, said covering section being flexibly resilient and preformed into a predetermined shape, said covering section adapted to extend from said mounting section outwardly toward the second structural substrate into flexibly resilient abutting engagement therewith without being permanently secured thereto to facilitate sealing engagement thereagainst for facilitating maintaining sealing engagement therewith during independent relative movement between the first and second structural substrates;
- B. a securement means for fixedly and permanently securing said mounting section of said sealing member with respect to the first structural substrate;
- C. a scrim means extending over said mounting section and said covering section of said sealing member to facilitate sealing of the joint gap between the first structural substrate and the second structural substrate, said scrim means being affixed to said mounting section and said covering section of said sealing member to facilitate securement thereof to the first structural substrate and sealing thereof with respect to the second structural substrate, said scrim means extending outwardly beyond said covering section of said sealing member to facilitate sealing thereof with respect to the second structural substrate, said scrim means extending over said mounting section and over and outwardly beyond said covering section of said sealing member to facilitate sealing of the joint gap between the first structural substrate and the second structural substrate;
- and
- D. a seal enhancing layer applied extending over said sealing member on top of said scrim means to facilitate sealing of the gap between the first structural substrate and the second structural substrate, said seal enhancing layer including an intumescent material component therein to further facilitate sealing of the gap between the first structural substrate and the second structural substrate responsive to a excessive heat, adherence of said seal enhancing layer to said mounting section and said covering section being enhanced by engagement thereof to said scrim means extending thereover and adjacent to the second structural substrate.
