DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0024] Before explaining at least one embodiment of the inventive concept disclosed herein in detail, it is to be understood that the inventive concept is not limited in its application to the details of construction, and/or the arrangement of the components set forth in the following description, or illustrated in the drawings. The presently disclosed and claimed inventive concept is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for purpose of description only and should not be regarded as limiting in any way.

[0025] In the following detailed description of embodiments of the inventive concept, numerous specific details are set forth in order to provide a more thorough understanding of the inventive concept. However, it will be apparent to one of ordinary skill in the art that the inventive concept within the disclosure may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the instant disclosure.

[0026] Further, unless expressly stated to the contrary, or refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by anyone of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0027] In addition, use of the a or an are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the inventive concept. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

[0028] Referring now to the drawings, and more particularly to FIGS. 1A and 1B, a pair of barrier systems 100 constructed in accordance with the inventive concepts disclosed herein are shown incorporated within a structure 102 to form a physical barrier against the infestation of pests into the structure 102. The structure 102 is shown to include a wall 104 formed of a plurality of insulating concrete form (ICF) blocks 10. An exterior side of the wall 104 has a finishing material 108 (e.g., a brick veneer), and an interior side of the wall 104 includes a concrete slab 110. As will be described below, the ICF blocks 10 have a first foam panel 12 and a second foam panel 14 supported in a spaced apart, parallel relationship to form a concrete receiving cavity. The concrete receiving cavity receives concrete for forming a concrete core 112.

[0029] Referring now to FIG. 2, an exemplary ICF block 10 is illustrated. The ICF block 10 is referred to as a knockdown insulating concrete block because the block 10 is adapted to be shipped in a flat, unassembled condition, and then assembled at a job site. Once assembled, the ICF block 10 is adapted to be interlocked with other insulating construction blocks to form an insulating concrete form for casting concrete. The ICF block 10 is formed from two foam panels 12 and 14 interconnected to one another with a plurality of web structure assemblies 16.

[0030] Each of the panels 12 and 14 has a top end 18, a bottom end 20, a first end 22, and a second end 24. Panel 12 also includes an exterior side 140 and an interior side 142, and panel 14 includes an exterior side 146 and an interior side 144. The top end 18 and the bottom end 20 of the panel 12 are shown to be provided with an outside row of a plurality of projections 26 which are spaced apart to define a plurality of corresponding recesses 28 and an inside row of projections 30 and 30a which are spaced apart to define a plurality of recesses 32. The projections 30 and 30a of the inside row are different in size to one another and are alternated relative to one another. Moreover, the projections 30 and 30a of the inside row are each different in size to the projections 26 of the outside row. The projections and recesses along the bottom end 20 of each panel 12 and 14 are offset relative to the top end 18 wherein a recess on the bottom end 20 opposes a projection on the top end 18 of corresponding size and a projection on the bottom end 20 opposes a recess on the top end 18 of corresponding size with the exception that the recesses of the inner rows are sized to receive either of the projections of the inner row.

[0031] It will be appreciated that while the panel 12 has been described to include alternating projections and recesses of varying sizes, numerous systems exist for interlocking insulating concrete forms. By way of example, the panel 14 has been illustrated to have projections of the same size. Other examples of panel structures are described in U.S. Pat. Nos. 6,820,384; 5,896,714; 4,698,947; 6,792,729; 6,401,419; and 5,014,480; each of which is expressly incorporated herein by reference.

[0032] The first end 22 and the second end 24 of the panels 12 and 14 may also be provided with a tongue and groove pattern that allows for a mating interconnection with the end of another panel. More specifically, the first end 22 of the panel 12 has an upper pair of projections 44 spaced apart to form a recess 46 and a lower projection 48 defining a pair of recesses 50 on each side thereof. Similarly, the second end 24 of the panel 12 is formed to have projections and recesses. However, the projections and recesses on the second end 24 are offset relative to the first end 22 wherein a recess on the second end 24 opposes a projection on the first end 22 and a projection on the second end 24 opposes a recess on the first end 22. In one version, the projections of the first and second ends 22 and 24 are provided with a shallow profile to permit the first and second ends 22 and 24 of the panel 12 to abut the end of another panel that may not have a corresponding tongue and groove pattern. For example, if a block is vertically cut, it is still desirable that the first and second ends abut a smooth end surface. To this end, a preferred height of the projections is approximately 1 mm.

[0033] The panels 12 and 14 can be formed from fire retardant expanded polypropylene, polystyrene, polyethylene or other suitable polymers, with expanded polystyrene commonly referred to as EPS being preferred. Subject to indentations and protrusions of minor dimensions, which can be any structure used to connect the forms together vertically to form a wall as discussed below, the panels are of generally uniform rectangular cross-section. In a typical case, each panel may be 48 inches long, 16.50 inches high and 2.50 inches thick. However, it will be appreciated that the panels may be constructed in a variety of shapes and sizes.

[0034] The exterior face of the panels 12 and 14 may be provided with a series of vertical markings and horizontal markings to serve as guidelines for assisting the installer to cut the block 10 to a desired size. The vertical markings are preferably spaced at one inch intervals; however, it will be appreciated that other intervals may be used. In addition, the vertical markings are identified with numerals much like a measuring tape. This allows an installer to cut blocks many times without the need of marking the cut point on the block, or without the need to measure the form during the cutting and installation process. This will save time and money during the installation process.

[0035] The horizontal markings may include a center line, a pair of upper lines, and a pair of lower lines. These horizontal lines may be spaced every 2 inches from the center line. This allows an installer making horizontal cuts to have a line to follow for cutting straight whether they cut directly on the line or not.

[0036] The panels 12 and 14 may further include a series of markings indicating the position of the web structures assemblies 16, and in particular an attachment element to be described below.

[0037] The panels 12 and 14 are assembled with the web structure assemblies 16 of desired dimension so that the outside rows are adjacent the outside of the block 10 and the inside rows are adjacent the inside of the block 10. In addition to the projections and recesses of the outside and inside rows alternating in the longitudinal direction, the projections and recesses alternate across the top end and the bottom end going from one panel 12 to the other panel 14. Similarly, the projections and recesses of the first and second ends of the panels 12 and 14 alternate going from the panel 12 to the panel 14. The projections and recesses permit the stacking and interconnection of a plurality of like blocks 10 as would be required in the construction of a wall or similar arrangement. Projections and recesses of the block 10 are substantially symmetrical, thereby permitting the interconnection of like blocks in a bi-directional and/or reversible manner.

[0038] Each web structure assembly 16 includes a pair of web inserts 50 and a pair of bridges 52. The web inserts 50 are adapted to be molded in the panels 12 and 14 while the bridges 52 are adapted to be connected to the web inserts 50 so as to extend between the panels 12 and 14.

[0039] The web structure assemblies 16 described herein may be constructed as described in U.S. Pat. No. 8,869,479, which is hereby expressly incorporated herein by reference in its entirety. It will be appreciated that other types of web structure can be used in accordance with the inventive concepts disclosed herein. By way of example, the web structure assemblies can be constructed as described in U.S. Pat. No. 8,181,414, which is hereby expressly incorporated herein by reference in its entirety.

[0040] Referring now to FIGS. 1A-1B, 3A-3C, and 4-5, the barrier system 100 includes a liner 120 and a support member 122. The support member 122 may serve as an impenetrable pest barrier and may hold the liner 120 and the vertically adjacent ICF blocks 10 in place during the process of constructing the structure. Alternatively, the barrier system 100 may include the support member 122 without the liner 120 (as shown in FIG. 4).

[0041] In one embodiment, the liner 120 is a flexible, stainless steel liner with an adhesive on one side for securing the liner 120 to the support member 122 in a manner to be described below. The liner 120 (FIG. 3B) may include a wider portion 170 and a thinner portion 172 and may serve to prevent the spread of structure fires. As will be discussed in further detail below, in one instance, the liner 120 is a sheet material sized to be positioned along the top end 18 of the panel 14 of the block 10, along a portion of the interior side 144 and exterior side 146, inwardly so as to be embedded in the concrete core 112, and outwardly so as to be embedded in the respective exterior material 108. In one embodiment, the liner 120 may have a width of about 9 inches and be provided with predetermined creased edge or score lines (not shown) to facilitate positioning of the liner 120 about the panels 12 and 14 and about the support member 122. An example of a suitable liner for use in the barrier system 100 is a stainless steel tape provided by York Manufacturing of Sanford, Maine under the trademark Yorkshield 304 SS.

[0042] With reference to FIG. 4, the support member 122 is a rigid member having a web 124 and a pair of flanges 126a and 126b extending from opposing ends of the web 124 to define a pair of panel receiving cavities 128a and 128b on opposing sides of the web 124. The first flange 126a has a first wing 130 extending outwardly and perpendicularly from the first flange 126a, and the second flange 126b has a second wing 132 extending outwardly and perpendicularly from the second flange 126b. The panel receiving cavities 128a and 128b are dimensioned to matingly receive a portion of the panels 12 and 14. In one version, the panel receiving cavities 128a and 128b may have a width of about 2.5 inches and a depth of about 1.75 inches. Also, the first wing 130 may have a width of about 0.5 inches, and the second wing 132 may have a width of about 1.75 inches. As illustrated in FIG. 5, the second wing 132 may be provided with a plurality of score lines 134 to facilitate altering the width of the second wing 132. In addition, the flange 126a may be provided with a score line 136 to facilitate removal of a top portion of the flange 126a, if desired. The support member 122 may be fabricated from a variety of polymeric materials, such as PVC or other commonly extruded resins. An inedible material helps create a barrier to pests. In an exemplary embodiment, the support member is extruded in four foot lengths and has a thickness of about 0.070 inches. It should be appreciated that the liner 120 may be secured to either the top or the bottom of support member 122, depending on the desired configuration.

[0043] With reference to FIGS. 1A-1B and 6, a method of installing the barrier system 100 for use with an ICF block, such as ICF blocks 10, is described. First, the ICF blocks 10 are stacked to a height required for placement of the barrier system 100. Installation of the barrier system may begin at a corner formed by the intersection of two ICF blocks 10, also referred to a corner block. Two support members, such as support members 122, are miter cut for placement into a corner block (not shown). Once installed, one of the support members 122 is positioned over the top end 18 of the panel 14 with the wing 132 extending from the exterior side 146 towards the finishing material 108, and another one of the support members 122 is positioned over the top end 18 of the panel 12 with the wing 132 extending from the exterior side 140 towards the concrete slab 110.

[0044] In an embodiment where the support member 122 is positioned on top of the liner 120, (such as in the embodiments shown in FIGS. 1A-1B and FIGS. 8A-8B), the liner 120 is rolled out onto the top ends 18 of the panels 12 and 14 of the ICF blocks 10 leaving approximately 2- of the liner 120 extending out from the edges of the corner block. The creased edge or score lines in the liner 120 are positioned on the top end 18 of the panel 14 and are aligned with the edges of the panel 14 leaving the wider portion 170 of the liner 120 extending from the score lines down the exterior side 146 of the panel 14. The thinner portion 172 of the liner 120 extends from the score lines down the interior side 144 of the panel 14. Similarly, the score lines in the liner 120 positioned on top end 18 of the panel 12 are aligned with the edges of the panel 12, leaving the wider portion 170 of the liner 120 extending from the exterior side 140 of the panel 12. The thinner portion 172 of the liner 120 is positioned at the score lines and extends down the interior side 144 of the panel 12.

[0045] In one embodiment, each of the liners 120 includes a paper backing. When the liner 120 is rolled out on the top ends 18 of the panels 12 and 14 and folded over the interior and exterior sides of the panels 12 and 14, the paper backing faces upwards.

[0046] Starting at a corner, each of the support members 122 is positioned on top of each of the liners 120, respectively, working down the wall. The support members 122 are positioned on the top ends 18 of the panels 12 and 14 prior to wrapping the liner 120 around the wings 130 and 132 of the support members 122. The wings 130 and 132 of the support members 122 are wiped clean to prepare for adhesive before proceeding to the next step. The paper backing of each portion of the liners 120 extending down the interior and exterior sides of the panels 12 and 14 is lightly scored before it is peeled back from the liner 120 to expose an adhesive.

[0047] Each of the support members 122 is securely held in place on top of each of the liners 120 as the portion of the liners 120 extending down the interior and exterior sides of the panels 12 and 14 is lifted away from the interior and exterior sides of the panels and the adhesive of the liner 120 is worked against the bottom surfaces of the wings 130 and 132 of the support members to remove any gaps or bubbles. The liner 120 is then folded over and around to the top surfaces of the wings 130 and 132 to form the liner 120 tightly around the small radius of the wings 130 and 132. The liner 120 is continuously pressed and formed onto the top surfaces of the wings 130 and 132 until it is fully sealed in place. The combination of an inedible support member and puncture resistant liner may increase the barrier systems effectiveness at preventing termite infestation.

[0048] In an alternative embodiment, where the liner 120 is positioned on top of the support member 122 (e.g., the embodiment shown in FIGS. 7A and 7B), proper orientation of the support member 122 on the top ends 18 of the panels 12 and 14 is ensured first. Then, the stainless steel liner 120 is folded at the predetermined creases or score lines to ease placement of a top ICF block 10 on top of the barrier system 100 positioned on a bottom ICF block 10. Next, the liner 120 is inserted into the panel receiving space 128b of the support member 122. After the liner 120 is positioned in the panel received space 128b of the support member 122, the top ICF block 10 is then positioned into the panel receiving space 128b of the support member 122, such that the top block 10 is adjacent to the stainless steel liner 120. Once the top ICF block 10 is secured, the steps discussed above for scoring the paper backing of the liner 120 and adhering the liner 120 to the wings 130 and 132 of the support member 122 are repeated, except that liner 120 is folded over and downward and secured to the bottom surfaces of the wings 130 and 132. It should be appreciated, however, that the liner 120 may be connected or adhered to the support member 122 by any suitable means known in the art.

[0049] In an embodiment where the barrier system 100 is used with a concrete floor system (e.g., the embodiments shown in FIGS. 1A-1B and 7A-7B), the liner 120 is set so that it is fully embedded into the concrete slab 112. To this end, at least inches coverage of concrete may be left over and under the wings 130 and 132.

[0050] The barrier system 100 may preferably extend to or past the exterior finish 108 of the wall. In an embodiment where the exterior finish 108 is brick, the barrier system 100 may extend into a mortar joint 180 between two rows of bricks or courses (as best shown in FIG. 6). Any holes are preferably grouted on the course above and below the barrier system 100 installation for sealing the same. In an embodiment where the exterior finish 108 is stucco or EIFS, the wing 132 extending away from the exterior side 146 of the panel and towards the exterior finish 108 is preferably shortened to extend flush or slightly beyond the exterior finish 108. Alternatively, it may be easier to inspect for termite mud tubes in exterior finishes, such as siding, if the wing 132 extending from the exterior side 146 of the panel 14 is not shortened.

[0051] Referring now to FIGS. 7A-7B, an example of the barrier system 100 for use with an ICF block to create a barrier between floors and prevent a fire from spreading is described. As discussed above, the barrier system 100 may prevent the chimney effect created in current foam panels. To prevent the chimney effect, the barrier system 100 may be installed between floors or between a top floor and an attic of ICF structures. As shown in FIGS. 7A-7B, the barrier system 100 may be used with a concrete floor, such as concrete floor 152 poured over a metal pan 154 for receiving the concrete floor. The concrete floor 152 is supported by a bar joist system 150. It should be appreciated, however, that that the barrier system 100 may be used with alternative floor systems with similar applications.

[0052] The wing 130 of the support member 122 extends from the interior side 142 of the panel 12 and into the concrete core 112, and the wing 132 extends from the exterior side 140 and into the concrete floor 152. Again, the wing 132 is shown fully encapsulated or embedded in the concrete floor 152. This may prevent any adhesive on the liner 120 from releasing during a fire.

[0053] In FIG. 7B, the liner 120 is shown on top of the support member 122 facing up. However, it should be appreciated that the barrier system 100 may be constructed with a concrete floor so that the liner 120 faces either up or down, depending on the desired orientation of the barrier system 100. In order to install the barrier system 100 for use as a fire-stop mechanism between concrete floors, a method similar to the method described above may be followed.

[0054] With reference to FIGS. 8A and 8B, an example of the barrier system 100 used with a wood joist floor system is described. The wood joist floor system may include a floor support member, such as a rim joist 160, floor joist members 162, hangers 164, and ledger connectors 166.

[0055] The barrier system 100 may be installed with the ICF blocks 10 by a method similar to that described above, except that the barrier system 100 is installed such that the wing 132 extends along the bottom of the rim joist 160 (as best shown in FIG. 8B), as opposed to being embedded in the floor material. It should be appreciated that the barrier system 100 may also be placed so that the wings 132 extend along the top of the rim joist 160. Additionally, each support member 122 may be sandwiched between the floor joist members 162. Furthermore, the barrier system 100 is preferably mechanically affixed to the rim joists 160, either with screws, such as screws 168 (e.g., 12 inch o.c.), or other means known in the art, to help prevent any adhesive formed between the liner 120 and the support member 122 from releasing during a fire and to help prevent the liner 120 from sagging during a fire. As discussed above, the barrier system may prevent the chimney effect at the foam panels 12 and 14 on the inside of the ICF block 10.
