Abstract
A fire resistive joint cover system operable to span a gap between two surfaces. The system generally may include first and second base members, a covering member, and an intumescent sheet. Each base member is operable to couple with one of the surfaces and the covering member is operable to couple with the base members to at least partially span the gap. In some embodiments, the covering member may be configured as a floating covering member and/or as a flexible elastomer seal.
Claims19
A joint cover system operable to span a gap between two surfaces, each surface including a top face and a side face, the system comprising:
- a first base member coupled with an uppermost portion of the top face of one of the surfaces, the first base member including a first leg;
- a second base member coupled with an uppermost portion of the top face of the other surface, the second base member including a first leg;
- a covering member monolithically formed with the base members to span the gap;
- an intumescent sheet uninterruptedly spanning the entire gap between the first base member and the second base member;
- and
- a unitary support structure including an inner surface and an outer surface, with the inner surface directly coupled with the intumescent sheet and at least a portion of the outer surface in direct contact with the side face of both surfaces,
- wherein the first leg of the first base member and the first leg of the second base member each perpendicularly couple to the covering member to create space between the covering member and the gap.

- a second base member coupled with an uppermost portion of the top face of the other surface, the second base member including a first leg;
- a covering member monolithically formed with the base members to span the gap, wherein the first leg of the first base member and the first leg of the second base member each perpendicularly couple to the covering member to create space between the covering member and the gap;
- an intumescent sheet uninterruptedly spanning the entire gap between the first base member and the second base member;
- and
- a unitary support structure including
- an inner surface and an outer surface, with the inner surface directly coupled with the intumescent sheet and at least a portion of the outer surface in direct contact with the side face of both surfaces, and
- a first flange coupled to a first edge of the support structure and a second flange coupled to an opposing second edge of the support structure with the first flange positioned between the first base member and the top face of one of the surfaces and the second flange positioned between the second base member and the top face of the other surface,
- wherein the support structure is operable to guide the expansion of the intumescent sheet toward the covering member during expansion of the intumescent sheet as a result of exposure to fire and to support the intumescent sheet once it has expanded.
A joint cover system operable to span a gap between two surfaces, each surface including a top face and a side face, the system comprising:
- a first base member coupled with an uppermost portion of the top face of one of the surfaces, the first base member including a first leg;
- a second base member coupled with an uppermost portion of the top face of the other surface, the second base member including a first leg;
- a discrete covering member, monolithically formed to span the gap, engaged with and supported by the base members;
- an intumescent sheet uninterruptedly spanning the entire gap between the first base member and the second base member;
- and
- a unitary support structure including an inner surface and an outer surface with the inner surface directly coupled with the intumescent sheet and at least a portion of the outer surface in direct contact with the side face of both surfaces,
- wherein the first leg of the first base member and the first leg of the second base member each perpendicularly couple to the covering member to create space between the covering member and the gap.
