Definitions

  • the present invention relates to a structural barrier, and more particularly to a structural barrier that is disposed between adjacent structures to inhibit the spread of sound, fire, smoke and other things through a gap between the adjacent structures.
  • walls typically extend between a floor and a ceiling in a room or other space.
  • a joint or gap sometimes is created. This is many times the case in commercial construction, where a building shell or a number of structural floors are first constructed. After construction of the shell or floors, walls are built to subdivide the shell or each floor into multiple rooms.
  • the walls typically include a bottom plate that is fastened to the floor.
  • the walls extend upward toward a ceiling.
  • the walls also include a top plate or top that is placed close to the ceiling.
  • walls are constructed slightly shorter than the distance between the floor and ceiling so that the top plate does not engage the ceiling as a wall is raised to a vertical configuration.
  • an opening is produced above the wall, below the ceiling.
  • Most fire and other building codes require this opening to be filled with a fire retardant, fireproof and/or sound deadening material. Frequently, these materials are applied in liquid, semi-liquid or sprayed foam form.
  • An installer usually manipulates a large applicator tube or caulk gun filled with a tube of the material, and aims a nozzle into the opening. The installer activates the tube or gun to squirt or spray a bead or amount of the material into the opening as the installer advances along the opening. The installer must perfectly time and move the nozzle at a constant rate to ensure the bead is of a uniform size so material is not wasted, and so enough material fills the opening to seal it between the wall and ceiling.
  • the materials are applied with a large tube or caulk gun, as mentioned above.
  • These applicators are large, bulky and unwieldy, particularly when the installer installs the material in an opening overhead, along a very long wall, or along multiple walls for multiple times during a workday.
  • the excess applied material must be removed to provide a finished appearance of the filler and adjacent walls.
  • the material may need to be cut and sometimes sanded away to smooth it flush with the adjacent wall or ceiling so that wall coverings or flooring can be applied.
  • the material when the material is hand applied and is semi-flowable upon application, the material often drips or runs down walls. It also can coat or otherwise fill gaps intended for wiring, plumbing and/or HVAC ducting. This can create a lot of extra work to remove the extra material.
  • An elongated structural barrier including a base, a first panel extending upward from the base, a first sealer wall extending downward and transversely to the base, a second panel joined with the first panel and extending upwardly, a lower wedge extending upward from the base adjacent the first sealer wall, and a core compartment bounded by the lower wedge and the panels, with an open face defined above the lower wedge and offering a view into the core compartment.
  • the elongated structural barrier can be easily and precisely installed between a variety of building structures to automatically seal a respective gap therebetween.
  • the barrier can include an upper wedge extending downward from a wiper end of the second panel toward the lower wedge.
  • the upper wedge and the lower wedge can cooperatively define the open face.
  • an elongated core can be disposed in the compartment.
  • the core can be of elongated construction and extends along a length of the base.
  • the core can include an exposed surface that is exposed to a viewer through the open face.
  • the core can be constructed from an intumescent material that swells due to exposure to heat against the lower wedge and the optional upper wedge. These wedges can cooperatively retain the core within the core compartment when the core swells. For example, in some cases, the upper wedge and the lower wedge can exert opposing forces on the core when it expands under heat to retain the core in the compartment.
  • the second panel extends upwardly along a curvilinear contour.
  • This curvilinear contour can include a radius of about 0.2 inches to about 0.6 inches.
  • This curvilinear contour can be convex upwardly, away from a horizontal reference line that bisects the core compartment into upper and lower portions.
  • This curvilinear contour and the second panel in general can be flexible, so as to automatically adjust to varying dimensions of a gap in which the barrier is placed. As a result, this can increase the range of the gap minimum and maximum fitment.
  • the barrier can include a transition wall that extends vertically and transversely to the horizontal reference plane.
  • the transition wall can join the first panel and the second panel.
  • the transition wall can be planar, while both the first panel and the second panel can be curvilinear, and convex away from the horizontal reference plane.
  • the core in the core compartment can be constructed from a fire retardant, fire proof and/or sound deadening material to further enhance the isolation functionality of the structural barrier placed in a gap.
  • the barrier can include a lower first flange extending from the first wedge.
  • the core compartment can include a first cavity and a second cavity.
  • the lower wedge can include a lower first flange extending toward the first panel.
  • the first cavity can be below the lower first flange.
  • the second cavity can be above the lower first flange.
  • the barrier can include a lower second flange joined with the first panel and extending toward the lower wedge.
  • the first cavity can be below the lower second flange.
  • the second cavity can be above the lower second flange.
  • the core can be constructed from an intumescent material that swells due to exposure to heat against the lower first flange and the lower second flange.
  • the lower first flange and the lower second flange can define a bloom gap therebetween.
  • the intumescent material can swell through the gap and into the second cavity of the core compartment when the core swells.
  • a method of installing an elongated structural barrier can include placing an elongated structural barrier in a gap between a first surface and a second surface of a building such that a first panel and a second panel are within the gap, with the first panel engaging the first surface and the second panel engaging the second surface above the first surface, and such that a base extends away from the first panel; placing a first sealer wall extending downward and transversely from the base against a third surface of the building that is substantially perpendicular to the first surface, with the first sealer wall at least impairing the first and second panels from being inserted too far into the gap between the first and second surfaces; moving the second panel downward toward the base, with the second panel bending along an arcuate contour toward the base, so that a height of the barrier automatically adjusts to allow the barrier to fit within the gap between the first surface and the second surface; and optionally applying a wall covering to the first sealer wall so that the first sealer wall melds into the third surface.
  • the method can be used where the first surface is an upper portion of a vertical wall, where the second surface is a horizontal surface above the vertical wall, spaced from the upper portion of the vertical wall by the gap, and where the third surface is a vertical surface of the vertical wall.
  • the applying step can include applying a material over a lower edge of the first sealer wall and over the vertical surface.
  • the method can include compressing an intumescent core within the core compartment.
  • the intumescent core can be retained within the core compartment via forces exerted by the respective first wedge and the second wedge against the core.
  • the core can be visible though the open face upon installation of the barrier within the gap.
  • the elongated structural barrier and related method of installation provide benefits in sealing or filling gaps between adjacent building structures that previously have been unachievable.
  • the elongated structural barrier can be rapidly installed within gaps overhead, down low, or in difficult to reach locations in a building.
  • the second panel is arcuate and flexible
  • the elongated structural barrier can compress or expand within a gap and automatically and adequately seal against the adjacent surfaces, regardless of varying dimensions of the gap therebetween.
  • the lower and/or upper wedges are included, these components can retain the core in the core compartment for a longer period of time to enhance fire protection.
  • the core can expand, but the wedges can exert opposing forces on the core to prevent it from ballooning out of the core compartment and/or the barrier.
  • the structural barrier can be in the form of an elongated structure. As shown in Fig. 2 , this elongated structure can have a length L. This length L can be of any predetermined length suitable for fitting between adjacent building structures, such as walls, ceilings, floors, roofs, etc. The predetermined length L can be optionally at least 1 foot, at least 2 feet, at least 3 feet, at least 4 feet, at least 6 feet or greater or lesser lengths, depending on the application and the length of the gap to be filled in, sealed or otherwise closed.
  • the structural barrier 510 can include a first panel 520 and a second panel 530.
  • the first panel 520 and second panel 530 can be joined via a transition wall 560.
  • the first panel 520 can extend to a base or extension wall 540 which itself can transition to a first sealer wall 550.
  • the second panel 530 which is shown disposed above the first panel 520, transition wall 560, extension wall 540 and first sealer wall 550, can terminate at a wiper end 537.
  • This wiper end 537 can be closer to the transition wall 560 than the first sealer wall 550, and can be configured to move in direction M such as when the barrier 510 is forced into a gap between structural members, optionally under force.
  • the barrier 510 can be equipped with one or more wedges, such as a first or upper wedge 581 that projects from the second panel 530 at or near the wiper end 537, distal from the transition wall 560, and/or a second or lower wedge 582 that projects from the base 540 at or near the first sealer wall 550.
  • the wedges 581 and 582 can define therebetween an open face 589, through which a fire resistant core 590 is visible to confirm via a visible inspection its presence in the barrier 510.
  • the open face design with the core also allows the first wedge 581 to flex toward the second wedge 582 when the core compresses under forces as described below, which in turn allows for significant variance in gap widths in which the barrier can be used.
  • first and second wedges 581, 582 can function to contain and restrain the core as the core 590 expands under elevated temperatures as described below. In some cases, the wedges redirect pressure from the expanding core to increase the retention force of the core within the barrier as described below.
  • the structural barrier 510 can be disposed between a first building surface 1 and a second building surface 2 to fill in, occlude, or partially or fully obstruct a gap G between the first surface 1 and the second surface 2.
  • the first surface 1 can be an upper portion of a wall W
  • the second building surface 2 can be a horizontal surface, such as that of a ceiling or a roof or other generally horizontal structure C in a building.
  • the gap G can be formed between other building surfaces.
  • the structural barrier 510 can be constructed from a variety of materials such as polymers, composites, metals and combinations thereof.
  • the structural barrier can be an extruded piece of polymeric material.
  • This polymeric material can be a fire resistant or fire retardant thermoplastic urethane (TPU).
  • TPU thermoplastic urethane
  • other types of polymeric materials can be used. These polymeric materials can be resistant to fire and/or thermal degradation or generally can burn at very slow rates. These polymeric materials can include polar monomers and/or hydrogen bonding between polymer chains to enhance fire resistance.
  • the polymers optionally can incorporate aromatic cycles or heterocycles, polyimides, polybenzoxazoles, polybenzimidazoles, and polybenzthiazoles are some examples of polymers suitable for the structural barrier.
  • the polymeric material can be a ladder polymer, which links to polymer chains with periodic covalent bonds, or can be a single chain that is double-stranded.
  • the polymeric material can include an inorganic and/or semi-organic polymer having silicon-nitrogen, boron-nitrogen and/or phosphorus-nitrogen monomers.
  • the polymeric material can include a flame retardant additive and/or filler. Examples of such an additive can include aluminum, phosphorus, nitrogen, antimony, chlorine, bromine, and in some cases magnesium, zinc and/or carbon. In some cases, where the structural barrier is constructed from a composite, that composite can include natural fibers that are fire retardant.
  • the structural barrier can be constructed from nano composites, carbon fibers and other carbon-based materials.
  • organic modified clays, titanium dioxide, nanoparticles, silica nanoparticles, layered double hydroxides, carbon nanotubes and polyhedral silsesquioxanes can be incorporated into and/or form the structural barrier.
  • the structural barrier can be constructed via extrusion. This can enable the structural barrier to be produced in elongated form and in a continuous, repeatable manner. Such extrusion also can facilitate manufacture of long pieces of the structural barrier, which optionally can be cut to custom or standard lengths for a particular job. These long pieces of structural barrier also can be rolled into rolls where the structural barrier material is flexible.
  • the elongated structural barrier can be constructed via injection molding, and pour molding with other techniques.
  • the structural barrier 510 can include a first panel 520, a second panel 530 and a base 540.
  • the base 540 can be a planar strip or sheet, and can extend from the first sealer wall or panel 550 to the first panel 520.
  • the base 540 can extend the length L of the barrier 510.
  • the base can include an upper surface 540U and an opposing lower surface 540L.
  • the upper surface can be flat and featureless, and configured to face and engage the core 590 as described below.
  • the lower surface can likewise be flat and featureless, however, in some cases, the lower surface can include ribs 540R. These ribs can be elongated, and can extend the length L of the barrier.
  • the ribs can be of a polygonal shape, or other shapes such as rounded, contoured or other shapes.
  • the ribs can engage and bite into drywall or other wall structures under the barrier 510 when installed. This can provide enhanced retention capability to hold the barrier in the gap G within which it is placed.
  • the upper surface can be void of ribs, as it typically only engages the core 590.
  • the base 540 can extend between the sealer wall 550 and the first panel 520.
  • the base can include a second or lower wedge 582 projecting therefrom. As shown, the wedge projects upwardly from the upper surface 540U of the base 540 at, near or adjacent the sealer wall 550.
  • the wedge can be a true wedge, with first 582A and second 582B walls tapering toward one another toward an apex 582P, or a thick flange having a uniform thickness extending upward from the base.
  • the wedge wall 582B can face toward the first panel 520 and/or the second panel 530 when the wedge is in its static condition shown in Figs. 1 and 2 .
  • the lower wedge can be set back a distance D4 from the outer or exterior surface of the first sealer wall 550. This distance can be equal to or greater than the thickness of the first sealer wall 550, depending on the application.
  • the first sealer wall 550 can be joined with the distal end 542 of the base 540.
  • the first sealer wall 550 can extend generally perpendicular to the first extension wall 540 and downward, away from the horizontal reference line RL, which can bisect the core compartment 590C generally into upper U and lower L parts.
  • the reference line RL also can correspond to a reference plane through which the reference line extends along the length L of the structural barrier 510.
  • the first sealer wall 550 can be of a planar or flat shape as shown, extending downward, away from the reference line RL or plane and the first extension wall or base 540.
  • the first sealer wall 550 can extend downward from the base 540 by a distance H3.
  • This distance H3 can be less than the overall height H1 plus H2 of the barrier 510 above the sealer wall 550, and optionally less than each of the heights H1 or H2 of the upper U and lower L parts of the core compartment or barrier itself.
  • the height H3 can be optionally 0.25 inches to 2.00 inches, inclusive, 0.5 inches to 1.5 inches inclusive, 0.75 inches to 1.25 inches, 0.5 inches to 1.00 inches, inclusive, about 1.00 inches, or other heights, depending on the application and the amount of overlap of an adjacent building surface 3, for example, a vertical surface of a wall W.
  • the first sealer wall 550 can be arcuate, and/or can include a curvature.
  • the sealer wall 550 can be somewhat rigid and inflexible, to assist in placement of the barrier in the gap G as described below. In other cases, the wall 550 can be resilient and can bend when the distal end 552 engages a third surface 3, which can be substantially perpendicular to the first surface 1 as shown in Fig. 4 .

As it does, the foam can bloom outward and in directions E, generally traversing through the bloom gap 788 defined between the lower flanges 771 and 772, or simply between the wedge 782 and the panels 720 or 760, when the flanges are not included. As this occurs, the foam material begins to engage the upper surfaces of the lower flanges, as well as the transition panel 760 where included, and the upper panel 730.
  • the foam can continue to expand outward through the open face 789 as shown in some applications. In so doing, it can pass beyond the reference plane RP of the first sealer wall 750 and/or the wedge 782. It also can pass beyond the free end 737 of the barrier 710. As will be appreciated, when the core swells and expands, it escapes through the bloom gap into the second cavity 790C2, moving upward therethrough and optionally filling the entire compartment 790C. With reference to Fig. 9 , when this occurs, the gap G, which is between the first surface 1 and the second surface 2, for example, between a wall and a ceiling, can be filled with a fire retardant material, that is the swollen intumescent material.
  • That material can continue to burn for a predetermined amount of time or until the fire or heat is suppressed or subsides. In this manner, the fire can be restricted from spreading via the barrier 710 from one space 51 on one side of the wall to another space 52 on the other side of the wall.
  • opposing structural barriers 710 can be installed within a gap G.
  • the barriers 710 can be disposed on opposite sides of the gap G over wall boards WB1 and WB2 that are adjacent a steel stud WS.
  • the barrier 710 can be pushed against the second surface 2 such that the second panel 730 and free end 737 can bend in direction M to accommodate the gap G.
  • the first panel which can form a portion of the base 740, can engage the first surface.
  • the second panel 730 can engage the second surface above the first surface.
  • the base also can extend away from the first panel.
  • the first sealer wall 750 can extend downward and transversely from the base against a third surface of the building substantially perpendicular to the first surface.
  • the first sealer wall 750 can optionally impair the first and second panels from being inserted too far into the gap G, in a manner similar to the embodiments above.
  • the second panel 730 can be moved in direction M, optionally downward toward the base 740. In so doing, the second panel 730 can bend along an arcuate contour toward the base. In this way, the height of the barrier automatically adjusts to allow the barrier to fit within the gap G between the first surface and the second surface.
  • a wallcovering can be applied over the first sealer wall so the first sealer wall melds into the third surface.
  • the first wedge 782 can be provided along the base 740 such that the open face 789 is disposed above the first wedge 782.
  • the first cavity 790C1 can be defined below the lower flange 771 extending from the wedge.
  • the first cavity can be defined below that flange.
  • a second cavity can be defined above the lower flange 771 and/or 772.
  • the barrier 710 can be constructed so that an intumescent core 790 can be positioned within the first cavity 790C1 and/or generally in the core compartment 790C as with the embodiments above.
  • the intumescent core can be retained within the first cavity at least partially by the lower flange and located adjacent the first wedge, the base and/or the first panel.
  • the intumescent core can be positioned so that it can swell upward, through the bloom gap 788 defined adjacent the lower first and/or second lower flanges 771 and/or 772 when exposed to heat. In this manner, with reference to Fig. 8 , and as mentioned above, the intumescent core can swell and move in direction E out from the first cavity and into the second cavity or generally expand throughout the core compartment to provide additional fire protection via the barrier 710.
  • the various components and features of the embodiments herein, for example, the structural barrier and its components, can take on a variety of aesthetic forms, shapes and sizes. Although a particular component or feature can have a function, that feature can be expressed in different aesthetic manners to form an artistic design and/or a purely ornamental design.
  • a component, part or layer when referred to as being “joined with,” “on,” “engaged with,” “adhered to,” “secured to,” or “coupled to” another component, part or layer, it may be directly joined with, on, engaged with, adhered to, secured to, or coupled to the other component, part or layer, or any number of intervening components, parts or layers may be present.
  • an element when an element is referred to as being “directly joined with,” “directly on,” “directly engaged with,” “directly adhered to,” “directly secured to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present.
  • any reference to claim elements as "at least one of X, Y and Z" is meant to include any one of X, Y or Z individually, and any combination of X, Y and Z, for example, X, Y, Z; X, Y; X, Z; and Y, Z, and/or any other possible combination together or alone of those elements, noting that the same is open ended and can include other elements.
