Definitions
- a variety of dynamic voids or joints are typically incorporated in a building in order to prevent damage as the structure undergoes movement due to thermal, wind and seismic loads.
- it is necessary to fit such voids with fire barriers. It is especially important for a fire harrier fitted to a joint to remain intact after the joint has undergone substantial displacement or distortion due to seismic activity, as the risk of fire is acute immediately following an earthquake.
- Fire barriers typically consist of a sheet of flexible material that is attached to each wall of the joint and loosely draped therebetween. Such configuration does not in any way impede the narrowing of the gap while the slack in the material accommodates a widening of the gap beyond its nominal width. Its inherent flexibility also allows the material to take up any differential vertical displacement between the two sides of the joint. Despite being flexible, the previously used barrier materials are, however, substantially less capable of accommodating relative lateral displacement between the sides of the joint, and are prone to shear failure.
- US-A-4942710 discloses an expansion joint for use between a pair of elongated, adjacent, relatively shiftable structural sections presenting therebetween an expansion void having a nominal width, the joint comprising a pair of elongated supports configured for fixed attachment to a respective structural section adjacent the expansion void, an elongated, flexible, bridging member composed of a fire-rated material having a width greater than the nominal width of the void and presenting a pair of respective, longitudinal edges, and means coupling said bridging member with said supports in a void-spanning relationship therewith and in a manner allowing lateral shifting of said member.
- EP 0 346 126 A2 discloses a fire barrier material for in building construction comprising a sandwich structure comprising a first and second outside layers comprising corrugated high temperature resistance metal and an intermediate layer comprising a flame retardant fibrous material.
- US-A-5304408 discloses an insulation blanket comprising a flexible and continuous aluminium-silica layer having upper and lower surfaces, a flexible thermal reflective sheet covering and attached to said upper surface of said aluminium-silica layer, said layer and said sheet forming a thermal barrier, and a flexible knitted wire mesh having interlocking loops surrounding said barrier and holding said barrier together.
- the present invention provides a fire barrier system that prevents the spread of smoke, heat and flame through a dynamic void such as a seismic joint.
- the system's configuration ensures that an effective barrier is maintained despite substantial relative displacement or distortion of the joint in all three dimensions.
- the barrier is relatively inexpensive, is easily installed, is readily retrofitted to many existing joint configurations and requires essentially no maintenance.
- the fire barrier system of the present invention consists of foil-backed insulative material supported in a free-floating manner by a woven metallic screen component that is draped between the two sides of the dynamic void.
- a loosely woven structure is critical in enabling the support component to accommodate relative lateral displacement of opposite edges without wrinkling or buckling.
- the ability of the individual wire elements to shift relative one another with a scissor-like motion serves to relieve shear stresses, and thereby provides for a uniform dimensional adjustment to lateral distortion. Because the insulation is supported in a free-floating manner by the support screen, the insulation essentially remains stationary and undistorted as the screen shifts and distorts to accommodate lateral displacement of the joint walls.
- the presence of the foil between the insulation and support screen reduces friction between the insulation and the support screen to insure free relative movement therebetween. The insulation material is thereby effectively isolated from shear forces that would otherwise be transferred thereto.
- a single support screen component may be employed to support the insuiation layer from below.
- the insulation layer maybe sandwiched between two woven metallic support screens so as to freely float therebetween.
- the system of the present invention is easily adaptable to horizontal and vertical applications, as well as transitions between horizontal and vertical surfaces.
- the barrier system of the present invention satisfies a need for a simple, easily installed, and relatively inexpensive device capable of preventing the spread of smoke, flame, and heat through a dynamic joint despite substantial distortion of such joint in all three dimensions.
- FIG. 1 illustrates an embodiment of the invention wherein the barrier system 12 is disposed between the two sides 14, 16 of a dynamic void extending across a horizontal surface.
- a support screen 18 and a retention screen 26 are disposed in parallel to one another, and are draped between the two sides of the void. The edges of the screens are rigidly affixed to the sides of the void by any appropriate fastening system.
- barrier material consisting of metallic foil 20, 24 backing positioned on either side of refractory matting 22.
- the layers may simply lie on top of one another or may be adhesively bonded to one another, or preferably, the structure may simply be held together by staples.
- the width of the foil backed material 22 is narrower than the width of the support screen 18, 26 such that its edges remain clear of the area where the screens converge and are fastened to the side of the joint.
- Intumescent fire caulking 29 is positioned along the edge of the refractory material
- the horizontal configuration illustrated in Fig. 1 is easily adapted to vertical configurations, as well as horizontal to vertical surface transitions.
- the screen preferably consists of stainless steel wires, about 0.0075" in diameter at 24 wires per inch.
- the use of stainless steel wire mesh with a wire diameter of 0.008" at approximately eight wires per inch has also been found to be advantageous due the material's exceptional flexibility.
- the refractory material preferably consists of 1/4" thick 12# ceramic fiber insulation blanket backed by 0.003" stainless steel foil on the hot side, and 0.003" aluminum foil on the opposite side.
- Fig. 2 shows an alternative embodiment wherein the barrier material includes an additional layer of insulation.
- the barrier material freely floats between woven stainless steel support and retention screens 30, 42, and consists of stainless steel foil backing 40 on the hot side, aluminum foil backing 32 on the opposite side, two layers of refractory matting 34, 38, and an additional septum layer of stainless steel foil 36 there between.
- Elements 32, 34, 36, 38, and 40 may simply lie on top of one another, may be adhesively bonded to one another, or are preferably stapled together.
- Fig. 3 illustrates an alternative embodiment of the barrier system wherein the retention screen 26 of the embodiment illustrated in Fig. 1 is replaced by retention flanges 58 and 60.
- the barrier material consisting of foil backing 52, 56 on either side of refractory matting 54, is supported in a free-floating manner by support screen 50.
- the support screen has a loosely woven structure that allows its individual wire elements to shift relative one another such that lateral distortion does not result in shearing, buckling, or wrinkling.
- a rigid retention flange 58 is attached to the side 46 ofthe joint to positively hold screen 50 in position, while its projecting lip 59 loosely retains the barrier material in position over the screen and across the joint.
- FIG. 3 illustrates an adaptation of the device to a transition between a horizontal and vertical surface whereby an appropriately modified flange 62 is attached to the vertical wall.
- the flange again performs the dual function of affixing the edge of the screen 50 to the joint wall 48, while its projecting lip 61 controls the position of the barrier material.
- the single support screen configuration can, forcourse, also be adapted to a horizontal application wherein two L-shaped retention flanges 58 are used, as well as wholly vertical applications wherein two Z-shaped retention flanges 60 are employed.
- the barrier system of the present invention not only accommodates relative movement of the sides toward and away from one another, as well as relative up and down movement, but allows for relative lateral displacement.
- the scissor-like freedom of movement of the individual wires forming the woven support screen allow opposite edges of the screen to be shifted laterally relative one another without causing the screen to buckle or wrinkle, such that the foil-backed insulative material floating thereon is effectively isolated from any shear forces.
- the insulation is thereby able to continue to fulfill itsinsulative function during and after three dimensional relative displacement of the surfaces that define the joint.
