Abstract: Fire-barriers systems, including pre-assembled intersecting and straight-line fire-barriers having either all male-, all female-, or both types of coupling ends eliminate on-site cutting and construction of barriers required for intersection-spaces and provide easy, rapid, and safe one-step, drop-in installation and coupling. All male/female ended fire-barriers are constructed as single-piece units. All adjacent laid-flat layers are continuously connected having no gaps or folds. Straight-line and L-shaped barriers are certified according to the criteria mandated by both the ASTM E 1399-97 (Reapproved 2005), Standard Test Method for Cyclic Movement and Measuring the Minimum and Maximum Joint Widths of Architectural Joint Systems and the UL 2079 Fire Resistance of Building Joint Systems Test for air leakage (Revised and relocated as 1.14 Mar. 10, 2006).

Abstract: An example of a pre-assembled, moisture, water, and gas impermeable fire-barrier system for use in expansion-joint spaces includes a fire-barrier having a layer of outermost protective cloth layer overlain by an insulation blanket overlain by stainless steel foil, overlain by a second insulation blanket, overlain by a limited layer of intumescent material, overlain by impermeable silicon coated cloth to completely or partially surround all of the other layers of the barrier. If desired, a first attachment apparatus for attaching a first long edge of the fire-barrier to a building unit and a second attachment apparatus for attaching the opposing second long edge to an opposing spaced building unit may be fixedly attached to the barrier. The barrier system may be fitted with a drain aperture and a drainage hose emanating from the aperture, the hose protected from the heat of a fire.

Abstract: Multi-layered, fire-barriers each sized and shaped for installation into accepting intersection-spaces formed by the spaced-intersection of at least two expansion-joint spaces that occur between two adjacent spaced structural building units, each of said expansion-joint spaces defined by a plane, said plane defined by a set of three non-colinear points with each point defined by a set of x, y, z coordinates from the same coordinate system with no two of said coordinate sets being identical. The fire-barriers are shaped for use in 2-way planar, L-shaped expansion-joint spaces, T-shaped, cross-shaped, V-shaped, and vertical/horizontal L-shaped corner expansion-joint spaces, for example, and may comprise at least one layer of: protective cloth, insulating blanket, intumescent material, and mechanically supporting layer.

Abstract: Bottom mounted (anchored) fire barrier systems include UL 2079 and ASTM 1399 tested and certified fire barrier/retainer structures, especially useful for floor/floor, wall/floor, and wall/wall expansion joint spaces formed by spaced opposing pre-cast concrete building units of 4½ inches thickness. The use of this system in structures using pre-cast building units provides room for installation of mandated rubber boots into the limited expansion joint space. Each fire barrier has affixed to its outside long edges a metal retainer that is structured for holding the barrier correctly and tightly positioned to the building unit surfaces first for secure and tight anchoring and then for providing support for the barrier to prevent leakage of gas, flame, smoke, and heat during a fire. Providing for ease of installation there is a reusable installation tool, an optional guard unit, male/female connections between barrier sections, and a splice connector butt to connections.

Abstract: Two-sided and two-sided mirrored fire barriers having each of their two sides tested, rated, and certified for use in common spaces, such as spaces shared between two rooms are taught. Two-sided barriers require only one barrier and one installation, instead of the two presently needed. Two-sided barriers may have different construction and composition on each side; whereas each side of a mirrored fire barrier is a mirror image of the other. All two-sided barriers include top-mounted, bottom-mounted, and side-mounted barriers, gas and moisture impermeable barriers, and barriers shaped to fit into the expansion joint spaces created when a plurality of expansion joints intersect. The barriers are disposed to various sizes, lengths, widths, and depths, in addition to variations in shape, content, number and composition of layers, materials, and attachment means required to accommodate the variety of sizes and shapes of expansion-joint spaces and the desired rating, in terms of hours.

Abstract: Multi-directional, one-piece, tested and rated, inside-mount fire barriers requiring no splicing to fit into expansion joint corner-type spaces are presented. Accompanying low-cost, re-useable, size-adjustable installation tools designed for one-step, drop-in, installation of each style barrier, are also taught. To insure a tight-fit between each installed barrier and the building units forming the joint space, spreader press-fit tools which, if desired, may serve as fire barriers covers are taught. Described herein is a barrier that needs no splicing to be installed into a T-shaped joint space that is created by the convergence of three building structures. The present invention contemplates inside-mounted, one-piece barriers shaped to fit cross-shaped and various L-shaped expansion spaces. L-shaped fire barriers include barriers having a horizontal and a vertical arm that can occur in various configurations and barriers having two horizontal arms.
