The present disclosure relates to free-standing fence or wall systems, which are supported generally independent of other structures or buildings. Conventional free-standing walls or barriers are constructed using stones, bricks, or blocks, which are individually placed, stacked, and typically mortared to each other. The process of constructing such conventional walls is labor intensive and expensive. It would be advantageous to provide a free-standing fence or wall system that is lighter weight, modularized, and more easily installed, while still providing the appearance of a solid stone wall.
A free-standing fence system includes two or more posts and one or more substantially planar prefabricated panels. Each prefabricated panel is configured to be coupled to two of the posts. Each prefabricated panel comprises a foam core and a first veneer layer. The foam core has a first side and a second side. The first veneer layer is coupled to and substantially covers the entire first side of the foam core. The veneer layer comprises one or more veneer members. Each veneer member includes a decorative layer of a continuous natural stone material and a binding layer coupled to a rear surface of the decorative layer.
The description herein makes reference to the accompanying drawings, wherein like reference numerals refer to like parts throughout several views, and wherein:
As shown in
As used herein with respect to each panel 10, the term “side” generally refers to the largest planar surfaces of each panel 10 or each layer thereof, the term “end” refers the vertical surfaces extending between the sides, and the terms “top” and “bottom” refer to the upper and lower surfaces, respectively, extending between the sides. Each panel 10 has a width extending between ends 31, 32, a height extending between a top 33 and a bottom 34, and a thickness extending between decorative sides 35, 36, which is substantially smaller than both the width and height. For example, each panel 10 may have a width of eight feet, one of various different incremental heights (e.g., 2 feet, 4 feet, 6 feet), and a thickness of approximately 3.0 inches (e.g., between approximately 2.5 and 5.0 inches). According to other exemplary embodiments, each panel 10 may have a different width, height, and/or thickness. Additionally, as discussed below, each panel 10 may be configured to be cut to a desired length, and multiple panels 10 may be stacked to form a wall having a greater overall height than each individual panel 10.

Each veneer layer 16 comprises one or more veneer sheets or assemblies 17, which are coupled to the base layer 14 (or the core 12), so as to collectively substantially cover one or both sides of each panel 10 in their entirety. In embodiments with only one veneer assembly 17, the veneer assembly 17 continuously covers substantially the entire surface of the panel 10 (
Each veneer assembly 17 assembly includes one or more veneer pieces or members 17a, which are coupled to each other to form the veneer assembly 17. Each veneer member 17a generally includes a decorative layer 17b and a binding layer 17c. In embodiments where each veneer assembly 17 includes only one veneer member 17a (
Each veneer member 17a includes a decorative layer 17b and a binding layer 17c (e.g., adhesive or epoxy layer). The decorative layer 17b is a thin layer of continuous natural stone, which has been extracted from a source natural stone formation (e.g., a slab) as a continuous layer and forms the forward or outer surface of the panel 10. The binding layer 17c is coupled to and covers an entire rear or inner surface of the decorative layer 17b and is formed from an epoxy or other polymer adhesive. The binding layer 17c (e.g., the epoxy) may impregnate and cure at least partially within the material (e.g., natural stone) of the decorative layer 17b. The binding layer 17c functions to bind together the decorative layer 17b to maintain the decorative layer 17b with its original appearance or configuration when part of the natural stone formation (i.e., maintaining individual areas or components of the decorative layer 17b in their original, lateral relationships). Each veneer member 17a may have a nominal thickness of between approximately 1.0 to 4.0 mm. Relative to the core 12, each veneer member 17a is relatively thin (e.g., less than approximately 15% of the thickness of the core, or more preferably less than approximately 10%). The decorative layer 17b forms a minority of the thickness (e.g., approximately 0.4 to 1.25 mm, or approximately ⅓ or less of the decorative layer 17a thickness), while the binding layer 17c forms a majority of the thickness (e.g., approximately 0.8 mm to 3.5 mm, or approximately ⅔ of more of the decorative layer 17a thickness). Relative to the thickness of the core 12, the decorative layer 17b is relatively thin (e.g., between approximately 0.1 and 5% of the thickness of the core 12, or more preferably less than approximately 2.5% It should be noted that the aforementioned thicknesses are nominal, while the decorative layer 17b (especially if using a natural stone material) and/or binding layer 17c may vary in thickness, for example, by having localized roughness, undulations, or projections. According to other exemplary embodiments, the veneer member 17a, including the decorative layer 17b and the binding layer 17c thereof, may have different thicknesses.
The binding layer 17c is flexible and generally elastic, thereby allowing each veneer member 17a to bend, while still maintaining the decorative layer 17b with its original appearance, albeit forming a curved surface. For example, the binding layer 17c may allow for the veneer member 17a to bend to a radius of approximately twenty inches, and return to its original configuration without any noticeable visual change to an observer. As part of each panel 10, this resilient flexibility of each veneer member 17b advantageously provides that the appearance of each panel 10 may be maintained with dynamic flexing of the panel 10 (e.g., with wind loading, freeze/thaw cycles, and other forces) or static bending, either of which might otherwise cause different decorative materials (e.g., rigid stone or veneer) to crack or shift and change the appearance of the panel 10. The resilient flexibility of each veneer member 17b, thereby, allows the panel 10 to be constructed with different structural properties and features (e.g., lighter weight, less rigidity, etc.) from those required for other decorative materials, which may provide various other advantages (e.g., modularity, assembly, transport, etc.).
Each veneer assembly 17 may further include a backing or adhesive layer 17d. The backing layer 17d is an intermediate layer, which couples the veneer assembly 17 to the underlying layer of the panel 10 (e.g., core 12, as shown in
According to an exemplary embodiment, the backing layer 17d is an adhesive tape product having a flexible polymer sheet material (e.g., a foam or membrane), which covers an entire rear surface of the veneer member 17a. The backing layer 17d includes or has applied thereto an adhesive (not shown) spread continuously or intermittently on a forward surface thereof, which is suitable for adhering the polymer sheet of the backing layer 17d to the binding layer 17c of the one or more veneer members 17b. The backing layer 17d may further include or have applied thereto an adhesive (not shown) spread continuously or intermittently on a rearward surface thereof, which is suitable for adhering to the underlying layer of the panel 10 (e.g., the core 12 or the base layer 14). The backing layer 17d may, for example, be a single- or double-sided 3M™ VHB™ adhesive tape product. With the adhesives bonding continuously to the surfaces of the base layer 14 (or the core 12 if no base layer 14 is included) and the veneer assemblies 10, the veneer assemblies 17 form a substantially continuous rigid outer shell (e.g., by way of the binding layer 17c and/or the decorative layer 17b) that adds bending rigidity to the panel 10, especially when coupled to both backing layers 17d (or to each side of the core 12).
According to other exemplary embodiments, the backing layer 17d may be a woven, mesh, or otherwise porous material (e.g., fiberglass or other fabric) coupled to the binding layer 17c with an intermediate adhesive (not shown) (e.g., epoxy cured separately from the adhesive layer 17b, glue, or other suitable adhesive), which may be spread intermittently or continuously between the substrate layer 17c and adhesive layer 17b of each of the one or more stone pieces of the decorative layer 17a.
It should be noted that the thickness of the veneer member 17a, including the thicknesses of the decorative layer 17b and binding layer 17c, are nominal thickness and may vary throughout a given veneer member 17a, especially considering where the decorative layer 17b is natural stone. This may result in the visible outer surface of the decorative layer 17b and/or the rear surface (i.e., facing the core 12) of the binding layer 17c having several localized undulations (e.g., protrusions, irregularities, roughness, etc.) that extend rearward in a generally normal direction relative to the visible surface of the decorative layer 17b. Accordingly, it may be advantageous to adhere the binding layer 17c, or other uneven rear surface (e.g., the backing layer 17d) of the veneer member 17a, to the base layer 14 or to the core 12 with a compliant material. The compliant material may be a curable adhesive or include compliant intermediate layer that receives or accommodate the localized undulations to still allow for a substantially continuous bond across the entire surface of the binding layer 17c. For example, a curable adhesive, applied with sufficient thickness, receives and cures to the localized undulations, as well as the surrounding areas of the binding layer 17c. Similarly, the compliant material may include a compliant layer of sufficient thickness and having a thin adhesive applied thereto (e.g., such as foam, for example, of a single- or double-sided tape), allows the localized undulations to press/deform the compliant layer, while the thin adhesive bonds to the rough surface and/or localized undulations, as well as the surrounding areas of the binding layer 17. The compliant intermediate layer may be formed by the backing layer 17d. In contrast, if the localized undulations 17c were instead applied directly to a non-compliant surface (e.g., the base layer 14 of a cured cementitious material), bonding to the binding layer 17c in regions having localized undulations may be limited due to point contact.
Additionally, any adhesive for coupling the veneer assembly 17a to the panel 10 must account for the differing properties of the base layer 14 (e.g., being cementitious) or the core 12 (e.g., rigid foam; if no base layer 14 is included) from the binding layer 17c (e.g., epoxy). For example, a curable adhesive must be capable of bonding to both the material of the base layer 14 (or core 12) and that of the binding layer 17c. Alternatively, if an intermediate layer is provided (e.g., such as the binding layer 17d, or other compliant layer referenced above, or tape), then the thin adhesive materials on each side of the intermediate layers may be differently suited for bonding to the different materials, or be the same material suited for the different materials of the base layer 14 (or core 12) and the binding layer 17c.
According to other exemplary embodiments, one, more, or all of the inner layers of the veneer assembly 17 may be omitted or added. For example, the binding layer 17c may be coupled directly to the core 12 or base layer 14 with a suitable adhesive (i.e., omitting the backing layer 17d, as referenced above), or other or different intermediate layers with suitable adhesives may be used (e.g., a woven, mesh, or other porous material being disposed between the backing layer 17d and the binding layer 17c of the veneer member 17a). According to still other exemplary embodiments the veneer layer 16 may be provided as stucco or other curable material, which is applied directly to the base layer 14 of the panel 10.
With reference to
The upper structural member 22 is coupled to the core 12 at the top 33 of the panel 10 and spans generally the entire width W between the ends 31, 32 of the panel 10. The upper structural member 22 has a generally constant cross-section with a laterally extending upper segment or web 22a and one or more central, spaced-apart segments or flanges 22b, 22c that extend downward from the upper segment 22a (e.g., at generally perpendicular angles). The upper segment 22a spans a lateral distance so as to cover upper edges of the core 12, base layer 14, and veneer layer 16. A lower surface of the lateral segment 22a is positioned against or proximate to top surfaces or edges of the core 12, base layers 14, and veneer layers 16, while the downwardly protruding segments 22b, 22c extend into receiving slots in an interior portion of the core 12. Mating surfaces of the structural member 22 and the core 12 are coupled to each other, for example, with an adhesive, or alternatively with the foam of the core 12 curing directly to the upper structural member 22.
The upper structural member 22 may additionally include two outer segments or flanges 22d, 22e that extend downwardly from or proximate to outer edges of the laterally extending segment 22a a relatively short height as compared to the central segments 22b, 22c. The two outer segments 22d, 22e extend downward so as to cover horizontal joint or gap between the upper edge of the veneer layer 16 and lower surface of the upper segment 22a, and may also form a drip edge to prevent water intrusion into the panel 20 (e.g., through surface tension). The two outer segments 22d, 22e are spaced apart a distance approximately equal to the thickness of the panel 10 (i.e., between outer surfaces of opposite veneer layers 16) plus any further distance required to form the drip edge and/or account for any variation in the thickness of the panel 10 (e.g., variation in thicknesses of the core 12, base layer 14, veneer layer 16, and any adhesives therebetween).
The lower structural member 24 is configured and coupled to the panel 10 in substantially similar manners as the upper structural member 22, albeit with central segments 24b, 24c and outer segments 24d, 24e extending upward from a central segment 24a into the core 12 and adjacent the veneer layer 16, respectively. The lower structural member 24 additionally includes apertures (e.g., weep holes; not shown) extending through the central segment 24a (e.g., between the central segments 24b, 24c and outer segments 24d, 24e) to provide a leak path for water to exit the lower structural member 24.
The one or more intermediate structural members 26, if utilized, are positioned at an intermediate height between the top 33 and bottom 34 of the panel 10 and span generally the entire width between the ends 31, 32 of the panel. Each intermediate structural member 26 has a generally constant H-shaped cross-section with a central web or segment 26a and two side segments or legs 26b, 26c extending upward and downward from edges of the central segment 26a. In one embodiment shown in
According to another embodiment shown in
Each intermediate structural member 26 has a width (e.g., between approximately 2.0 and 3.0 inches) that is less than a thickness of the core 12 (e.g., between approximately 3.0 and 4.0 inches), so as to be encased by the foam of the core 12 (i.e., of a single foam panel, or multiple foam panels 12a, 12b, etc.) with at least an outer portion of the core 12 (e.g., between approximately 0.5 and 1.0 inches) being arranged between the intermediate structural member 26 and the base layer 14 or veneer layer 16 coupled thereto. By encasing the intermediate structural member 26, the base layer 14 may be applied to the surface of a single type of material with consistent adherence properties. Furthermore, the outer portion of the core 12 insulates the intermediate structural member 26, which is made from a heat conductive material and might otherwise transfer heat between the two sides of the panel 10 (e.g., between sunny and shaded sides), which may cause localized differences of appearance due to temperature differences in regions adjacent the structural member 26 (e.g., from condensation forming on the veneer layer 16).
As shown in
The posts 40 may be configured either as intermediate posts 40 (
By configuring each intermediate post 40 with lateral segments 44 extending in opposite directions from the central segment 42 (i.e., with a Z-shaped cross-section), the posts 40 allow for simplified installation of the panels 10 for both generally straight portions and corner sections of the fence system 1. In particular, the Z-shaped posts allow for horizontal placement of the panels 10 adjacent the lateral segments 44 of the post 40, as opposed to vertical insertion if the panels 10 were instead received in U-shaped channels of a post.
For example, if the lateral segments 44 of two posts 40 are positioned on a common side of the panel 10, the panel 10 may simply be oriented with the sides 35, 36 and ends 31, 32 thereof extending substantially vertically (i.e., a vertical orientation) and then moved laterally such that one of the decorative sides 35, 36 (i.e., having the veneer layer 16) or an intermediate material (e.g., a protective material) is placed against the lateral segments 44 of the two posts 40 with opposite ends 31, 32 of the panel 10 being positioned adjacent the central segment 42 of the two posts 40. Alternatively, if the lateral segments 44 of two posts 40 are positioned on opposite decorative sides 35, 36 of the panel 10, the panel 10 may be moved into the vertical orientation, moved laterally to a position between the two posts 40, and pivoted for the each decorative side 35, 36 to engage the lateral segment 44 of one of the posts 40 with the ends 31, 32 of the panel 10 being positions adjacent the central segments 42 of the two posts 40. The panel 10 may then be fastened to the lateral segment 44 of the post 40 (as described below).
For perpendicular corners (e.g., where adjacent panels 10 form an angle of approximately 90), one lateral segment 44 of the post 40 is positioned toward the outermost portion of the intersection, with a decorative 35 and an end 31 of one panel 10 being positioned against the central segment 42 and lateral segment 44 and, respectively of the post 40. For non-perpendicular corners, the panels 10 may be coupled to the post 40 in other manners as may be deemed appropriate and/or may be field cut (e.g., using a circular saw with a diamond- or carbide-tipped blade of sufficient size to extend entirely through the thickness of the panel 10) such that the surface of the ends 31, 32 are not perpendicular to the decorative sides 35, 36. The panel 10 may also be cut to an appropriate or desired length.
To provide fence systems 1 with greater height, panels 10 may be provided with different heights (as described above) and may be stacked on top of each other with the lower structural member 24 of an upper panel 10 resting on the upper structural member 22 of a lower panel 10. To prevent unequal bowing between the stacked panels 10, the lower structural member 24 of the upper panel 10 may be coupled to the upper structural member 22 of the lower panel 10, for example, using mechanical fasteners and/or a suitable adhesive. To account for varying slopes, the panel 10 (or a bottom panel 10) may be embedded into the ground, thus providing a fence system 1 that extends continuously upward from the ground across varying slopes.
To attach the panel 10 to each post 40, fasteners 60 extend through the lateral segment 44 of the post 40 through the veneer layer 16, base layer 14, core 12, and into each structural member (e.g., at least one of the central segments 22b, 22c of the upper structural member 22 as shown in
As shown in
As shown in
Each panel 210 is configured in one of the layered manners described above for panels 10 (e.g., refer to discussion of the core 12, the decorative layer 16 of veneer assemblies 17, and in some embodiments, the base layer 14). In preferred embodiments, each panel 210 does not include structural members incorporated therewith (e.g., upper, lower, and intermediate structural members 22, 24, 26). Instead, the panels 210 are engaged and/or are supported the upper, lower, and intermediate cross members 250, 260, 270, which are provided separately from the panels 210. That is, the cross members 250, 260, 270 are not part of the modular panel 210. The panels 210 may be provided in a standard size, such as with a common height (e.g., approximately two feet) and a common width (e.g., eight feet), which is easily maneuverable by one or more people, and which may be cut to size by an end user for a particular application. According to other embodiments, the panels 210 may, however, still include one or more of the upper, lower, and/or intermediate structural members 22, 24, 26.
As shown in
The outer segments 243 of the post 240 are spaced apart a distance that accommodates receipt of the panels 210 and cross members 250, 260, 270 therein (e.g., between the protrusions forming the channels 244). For example, the outer segments 243 may be spaced apart a distance or gap that is slightly greater than outer widths of the cross members 250, 260, 270 (e.g., by approximately one millimeter). According to some embodiments, this small gap allows the inner surfaces of the outer segments 243 to be drawn into engagement and be maintained in contact with outer surfaces of cross-members 250, 260, 270 (e.g., with the threaded fasteners 280), such that friction therebetween, in addition to the shear strength of the threaded fasteners 280, maintains the cross-members 250, 260, 270 at a constant height.
As shown in
As shown in
In fence systems 100 requiring greater height, multiple panels 210 may be stacked vertically. In such instances, one of the intermediate cross-members 270 is positioned vertically between two stacked panels 210. Each intermediate cross member 270 defines an upper recess 271A for receiving the lower end of one panel 210 and a lower recess 271B for receiving the upper end of another panel 210. Each intermediate cross-member 270 includes a central segment 272 (e.g., a web) and two outer segments 253 (e.g., flange, or leg) that are spaced apart by the central segment 272. The two outer segments 253 extend upward and downward therefrom in parallel to define the upper and lower recesses 271A, 271B on upper and lower sides of the central segment 272. In addition to preventing horizontal bending of the panels 210 thereabove and therebelow, the intermediate cross member 270 also functions to vertically support the panel 210 thereabove by spanning between and being coupled to two of the posts 240. The intermediate cross member 270 may additionally include weep holes (not shown) in the central segment 262 to facilitate draining of water that might otherwise collect in the upper recess 271A.
The posts 240 and cross-members 250, 260, 270 may, for example be made of extruded aluminum or other suitable material, which is colored (e.g., powder coated, anodized, etc.) to match, complement, or otherwise coordinate with a color of the decorative layer 27b of the panels 210.
To install the freestanding fence system 201, two of the posts 240 are embedded into the ground (e.g., with concrete, as described above) at a predetermined distance apart (e.g., with the center webs 242 being approximately eight feet apart) with one of the recesses 241 of each post 240 being aligned and oriented with each other. A lower structural member 260 is then inserted into the recesses 241 of the two posts 240, arranged in its desired height and orientation (e.g., horizontal), and then coupled to the two posts 240 with fasteners 280.
A first or lower panel 210 is then inserted into the recesses 241 of the two posts 241 and coupled thereto. More particularly, the lower panel 210 is raised above upper ends of the posts 240 and lowered into the recesses or channels 241 until resting on the lower structural member 260 in the recess 261. It should be noted that because the thickness of the panel 210 is less than the width of the recess 261 of the cross member 260 (i.e., for receipt therein), an even larger gap is formed between the recess 241 of the post 240 (i.e., being sufficient to receive the cross-members 250, 260, 270 therein) and the panel 210, which facilitates sliding down of the panel 210 to its resting position. The panel 210 is then coupled to the two posts 240 with fasteners 280 inserted into the channels 244. For example, a common fastener 280 may be used to couple the panel 210 and the cross member 260 to the post 240 (i.e., with a single fastener shaft extending through the outer segment 243 of the post 240, the outer segment 263 of the cross member 260, and into the panel 210. Such a fastener may also extend entirely through the panel 210 and opposite outer segment 263 of the cross member 260, and opposite outer segment 243 of the post 240 (e.g., to receive a nut thereon). When using a common fastener for coupling both the lower cross member 260 and the panel 210 to the post 240, the lower cross member 260 must be supported in its desired orientation and position until the lower cross member 260 and the panel 210 are simultaneously coupled to the post 240. Further fasteners may (e.g., at different vertical locations) may further couple the panel 210 to the posts 240. According to another alternative method, the lower panel 210 may be embedded into the ground, in which case the lower cross-member 260 may be omitted with the panel 210 being supported vertically by the ground and/or fasteners.
In applications using multiple stacked panels 210 (e.g., three stacked panels 210, as shown in
After the uppermost panel 210 is installed, which may be the lower panel 210 (i.e., in installations being only one panel high), the upper cross-member 250 is then inserted into the recesses 241 of the two posts 240, is arranged in its desired position and orientation (e.g., horizontal, so as to receive an upper end of the uppermost panel 210 in the recess 251 thereof), and is coupled to the two posts 240 with fasteners extending through the outer segments 241 an/or 251 of the post 240 and upper cross member 250, respectively, and into the panel 210, in the manner described above.
This installation process described above is repeated for additional horizontal sections with adjacent fence sections using a common post 240. Depending on the application, the panels 210, posts 240, and/or cross members 250, 260, 270 may also be field cut to length and/or angle to achieve a desired size.
