The field of the present invention relates generally to building materials and, in particular, to building materials having characteristics for withstanding high velocity storms and earthquakes.
In the news recently were reports of as-yet unrepaired damage to broad sections of New Orleans caused by Hurricane Katrina, a storm that occurred a decade ago. Houses and commercial buildings built using known construction materials and methods were heavily damaged by the wind and flooding of that storm, many of which were damaged beyond repair. Had materials used for New Orleans' buildings and housing had the strength to remain standing with roofs intact under such winds and water, then the news from New Orleans 10 years after the storm would have been far more positive. New Orleans is indeed a city that is justifiably proud to have weathered Katrina. Had the materials used for her buildings and housing had the strength and water-resistant characteristics to protect them from high winds and water, even more the extreme shaking of an earthquake as well, then, New Orleans pride would have included being completely restored from the hurricane damage long before 10-year commemoration news reports were written.
What is needed is a building material usefully employed for new construction or refitting of existing structures that is capable of resisting the high winds of a Katrina as well as the surging water that resulted from that storm. The invention presented herein below is a panel having such strength and water-resistance.

All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.
The n'ovel features of the invention are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
In one example, the present invention relates to a panel having characteristics of high strength to wind or projectiles or shaking as well as a high level of water resistance. It is intended that the inventive panels be used in place of the entirety of a wall or roof or floor. For example, an exterior wall of a house includes interior and exterior facades attached to a frame. The frame is comprised of wood studs regularly placed along the length of the wall. The prior art interior facade, today, is commonly composed of drywall or the like, i.e., an interior planar surface, secured to the studs of the frame. One typically applies paint or wall paper or wood paneling to the interior planar surface. The prior art exterior facade is typically formed by a sheathing (usually plywood) attached to the frame's studs and, covering the sheathing, is brick, stone, stucco, or siding. Between the interior and exterior facades of the outside wall, at least in well-constructed structures, is an insulating material, which commonly is fiberglass batts or a plastic that is blown into the interior voids of the wall, i.e., between the wall studs. All three portions of the exterior wall are preferably replaced by a panel of the present invention, which provides superior strength, superior insulation, and superior protection from precipitation of any form; and, further, has decorating-ready facade surfaces on the interior and exterior planar surfaces.
For example, the inventive panel, in one embodiment, provides an exterior surface (i.e., the surface that faces the outside environment on outside panels) that resists damage from projectiles, wind, or water. It also provides an interior surface (i.e., the surface that faces the inside environment) that can be painted or otherwise decorated. Lastly, the portion of the inventive panel between the exterior and interior surfaces includes a structure that acts as a truss and affords the panel extraordinary strength with flexibility for resisting forces that otherwise might push or pull the outer wall to a breaking point. For panels usefully employed for interior walls of a structure, i.e., wherein both sides of the panel face the inside environment, in most embodiments of the invention, it is generally the case that both sides of the panel have interior surfaces ready for decoration.
Overall, one embodiment of the inventive panel comprises an exterior surface that is not only water-resistant but also substantially impervious to projectiles that may crash into a house, as may occur during a storm that includes high velocity winds or, in extreme circumstances, gunfire. This inventive panel further comprises an interior surface that, as manufactured, can be used as is or can be painted, wall papered, or otherwise further finished per a user's tastes. The source of insulation and flexible strength lies between the interior and exterior surfaces where insulating material resides in the voids created by a zig-zag web. It is the zig-zag web that provides the flexible strength as its structure when attached at each apex to the inside surfaces of the interior and exterior facades forms a standard truss. With attachment of the apices of the zig-zag web attached to the inside surfaces of the interior/exterior surfaces, the inventive panel becomes a monolithic structure. It is the monolithic nature of the inventive panel that heightens the inherent flex and strength characteristics provided by the truss structure of the zig-zag web.
The thickness of the inventive panel varies with different embodiments thereof. For example, for inventive panels usefully employed as walls, i.e., employed with the broad planar surfaces in a vertical position, the typical range of thickness from outside planar surface to outside planar surface is from about two inches to about 24 inches. In other embodiments, the range of thicknesses can be from about three inches to about eight inches. In yet other embodiments, the range of thicknesses can be from about five inches to about six inches. As it happens, thicknesses can be dictated by pre-existing structures and the thicknesses of walls there. Older homes, for example, have walls built with standard two by four inch studs. Current tornado-resistant designs, on the other hand, commonly have walls between about five inches and about six inches.
Panels of the present invention usefully employed for a roof can have a range of thicknesses between about three inches and about 48 inches; preferably, the range of thicknesses of roof panels of the present invention is from about four inches to about 24 inches; and yet more preferably, the range is from about 10 inches to about 14 inches; and even more preferably, the roof panel of the present invention is about 12 inches thick.
Panels of the present invention usefully employed for a floor can have a range of thicknesses between about five inches and about 24 inches; preferably, the range of thicknesses of floor panels of the present invention is from about five inches to about 12 inches; and yet more preferably, the range is from about 11 inches to about 13 inches; and even more preferably, the floor panel of the present invention is about 12 inches thick, plus or minus a half inch.
Panels of the present invention usefully employed for a door can have a range of thicknesses between about one inch and about eight inches; preferably, the range of thicknesses of door panels of the present invention is from about one inch to about six inches; and yet more preferably, the range is from about two inches to about six inches; and even more preferably, the floor panel of the present invention is about two inches thick, plus or minus five-eighths of an inch.
Panels of the present invention usefully employed for a garage door can have a range of thicknesses between about four inches and about 18 inches; preferably, the range of thicknesses of garage door panels of the present invention is from about four inches to about 12 inches; and yet more preferably, the range is from about four inches to about eight inches; and even more preferably, the floor panel of the present invention is about six inches thick, plus or minus an inch.
Materials usefully employed for the planar materials that sandwich the internal webs of the present invention include, for example, carbon fiber with epoxy (i.e., a high strength fiberglass). Alternative materials include a flexural material for the web, i.e., the truss element of the inventive panel, and a stiffer material for the outside covering, i.e., the planar surface. A stiffer material for this purpose are bullet-resistant, such as a bullet resistant plaster that can be pumped or sprayed. One bullet resistant plaster is sold under the tradename Ballisticrete®. Other useful planar materials include, for example, steel plating starting from about 16 gauge to about 3 gauge; more preferably from about 12 gauge to about 4 gauge; yet more preferably from about 10 gauge to about 5 gauge. Another usefully employed material for the planar surfaces of the present invention is a pourable waterproof material having a fire rating. for example, a sprayable concrete material sprayed onto a fiberglass planar material is a good material for the present invention. One such product is sold under the tradename Gunnite®.
Floor panels manufactured in the context of the present invention can usefully employ cement board or exterior grade gypsum board for the planar material. Other suitable planar materials include any sheet to which is applied sprayed concrete, for example.
Aspects of the present invention may be better understood in reference to the Figures. As used herein, “inside” refers to the interior of the panel irrespective of which planar surface is referenced; and “outside” refers to the exterior of the planar surfaces. Also, the outside surface of the exterior planar surface is referred to here as the “exterior facade” and, analogously, the outside surface of the interior planar surface is referred to as the “interior facade.”
The invention employed in one embodiment is illustrated in
The structure of the interior of the inventive panel 10 includes a zig-zag web comprised of apices 106, where apex pairs 106a, 106b and 106c, 106d are “adjacent apices” and apex pairs 106a-106c, 106b-106c, and 106b-106d are “opposite apices.” The apices can vary in different embodiments of the invention. For example, the apices can be pointed (as in V-shaped webs illustrated by panel 10 of
Connecting opposite apices are arms 105, where arm 105a and arm 105b are “adjacent arms.” The space between adjacent arms are referred to as “voids,” such as void 103 and void 104. With the V-shaped apices shown in
Arms on V-shaped webs (e.g., web 70 or web 60, respectively) are straight and thus exhibit lesser flexibility in transferring received force relative to arms on U-shaped or corrugated webs (e.g., webs 80 or 90). With U-shaped apices, the attached arms generally have a curvilinear aspect that increases the ability of the arms to flex in response to a received force and may contribute to a greater capacity to dissipate the received force. The rib webs, i.e., web 60, for example, like V-shaped webs, also have straight arms, exhibit lesser flexibility in transferring received force thus delivering received force to the apex distal from the direction from which the force came.
Triangular tubes could still be used to deliver insulation to the voids of rib web-containing panels, however the void area would likely be inefficiently filled in view of the flat portion of the central apex of each void. Similarly, the voids of corrugated or U-shaped web-containing panels would also be inefficiently filled by triangular tubes, owing to the curvilinear aspect of its apices. Accordingly, when U-shaped apices are employed, it is preferred to use a flowable insulation material to fill the voids. Alternatively, one could instead opt for a malleable (i.e., stuffable) insulation material, such as a fiberglass batt, appropriately sized.
Arms 105 as shown in the embodiment of
Apices and the inside planar surfaces can also be attached by fiberglassing the web to the inside planar surfaces using a combination of polyester resin, catalyst (or hardener), and fiberglass fibers. Bundles of fiberglass, commonly in the form of a mat-like material, are distributed over the web and inside planar surfaces. For example, strips can be cut from the fiberglass mat that have a suitable width to cover the apices of the web; and the inside planar surface can also be covered with commensurate width strips of fiberglass mat at intervals that are substantially spaced and positioned relative to the apices of the web (or the entire inside planar surface is covered with a fiberglass mat). With the mat placed against the inside planar surface followed by application of the polyester resin to which has been added an appropriate proportion of catalyst (which proportion is specific to the concentrations included of these two components); and immediately thereafter or concurrently the mat strips positioned on the apices of one side of the web are also treated with the polyester resin—catalyst mixture; after which the inside planar surface is laid onto the fiberglassed apices of the web until the fiberglass sets. Once the apices of one side of the web has attached to the inside planar surface via the fiberglassing treatment, then the identical procedure is performed on the opposing side of the web and a second inside planar surface. Upon the second inside planar surface being fixed to the opposing side of the web, the panel of the present invention is formed. Other embodiments include the addition of insulating materials into the voids located between adjacent pairs of web arms (e.g., in
Fiberglassing kits are available from many construction supplies outlets, including, literally, any hardware store. For general supply of all components for fiberglassing, see, e.g., www.fiberglasssupply.com or any Ace Hardware or Home Depot or the like. The polyester resin and catalyst (or hardener) are provided separately and must be mixed prior to use. The mixture is stirred thoroughly using a paint stick or some other suitable, non-reactive material. The mixed poly resin—catalyst mixture is then liberally applied to the fiberglass mat, which then attaches to the web and one inside planar surface. Subsequently, a second fiberglass mat is applied to the other side of the web and the second inside planar surface; and, again, the poly resin—catalyst mixture is liberally applied causing the web to become fixed to both inside planar surfaces where the apices contact said surfaces. In this manner, the two planar materials and the web form a single unit. The strength of the inventive panel is derived from the monolithic nature of the attached planar materials that forms a sandwich of the web fixed there between.
In particular, broadening the methods of attachment and referring to
The voids 103, 104 and the like can be filled with insulation. Suitable insulation employed in the context of the present invention include board, batt, and flowable varieties so long as the insulation fits in and is deliverable to the voids. Insulation materials can be selected from the group consisting of a plastic, fiberglass, rock and slag wool, cellulose, natural fiber, vermiculite, perlite, papercrete, and foil; and combinations thereof. Indeed, any of the alternatives are particularly useful in combination with the reflective characteristics of foil. Suitable plastic insulation can be selected from the group consisting of a phenolic foam, a cementitious foam, a polyurethane, a polyisocyanurate, a urea-formaldehyde foam, a urea foam, a polystyrene, and a polyethylene foam.
The structure of
The pitch of the zig-zag web increases as the distance occupied between adjacent apices decreases; as indicated on
For the inventive panel, the distance between the parallel planes relates to its thickness. The greater distance between the parallel planes, the thicker the inventive panel will be. Further, the increasing distance between the parallel planes lends a greater potential R value as the voids will occupy greater volume in which more insulating material can be introduced. (The R value is a standard measurement of insulating capacity of a wall, as generally known in the construction arts.) Panels where the distance y is between about 1 inch and about 15 inches are usefully employed for different embodiments of the present invention; more particularly, inventive panels of various embodiments include a distance y that is about 2 inches, about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, about 11 inches, about 12 inches, about 13 inches, about 14 inches or about 15 inches are used for scenarios requiring greater or lesser insulating capacity as well as greater or lesser force-bearing capacity. For example, a first-floor outside wall for a three story building in Fairbanks, Ak. would call for a thicker exterior panel both for the added stress of withstanding the force exerted by two floors above the first floor as well as added insulating capacity of the larger void volume for maximizing the insulating material for holding off the extreme and extended cold of an Alaskan winter. In one embodiment, such an Alaskan building can require the distance y to be between about 8 inches thick to about 15 inches thick; in another embodiment, this Alaskan building can require the distance y to be between about 10 inches thick to about 15 inches thick; and in yet another embodiment, this Alaskan building can require the distance y to be between about 12 inches thick to about 15 inches thick.
In contrast, a single-floor tiny house located in New Mexico may be well served using exterior walls that are substantially narrower, where the distance y is between about 2 inches to about 8 inches. Of course, the first floor walls of a tiny house have only a roof to support and sand storms, seasonal rains and seasonal heat to withstand. Accordingly, the issue of what is an appropriate thickness of the zig-zag web may be usefully determined by the efficiency of the contained insulating material. In one embodiment, the distance y is between about 3 inches and about 8 inches; in another embodiment, the distance y is between about 4 inches and about 8 inches; and in yet another embodiment, the distance y is between about 5 inches and about 7 inches.
Where the weather tends to be more violent, as in tornado season in Kansas or Oklahoma, among other such geographies, the variable of greater concern can be the number of apices per unit length. The greater number of attachment points per unit length between apices and the inside surfaces of the internal and external planar materials, the stronger the inventive panel is likely to resist damage due to high wind or, worse, projectiles launched by high wind as commonly occurs in Tornado Alley. Accordingly, in one embodiment of inventive panels for employment in structures in Tornado Alley, the distance x in a panel 10 is between about 5 inches and about 12 inches; between about 5 inches and about 10 inches; between about 5 inches and about 10 inches.
The very same considerations are addressed irrespective of the profile of the zig-zag web that is employed for a particular inventive panel. Corrugated (also referred to as U-shaped) webs 80 or 90 as well as rib webs 60 are appropriately altered with regard to distance y regarding concerns of insulation capacity primarily and overall strength secondarily; and with regard to distance x regarding concerns of overall strength primarily for withstanding the extraordinary wind forces of Tornado Alley or a Florida hurricane season. In all cases, in the same manner is described above for the V-shaped web, the construction engineer will select inventive panels having the considered insulating capacity and/or strength capacity to meet the likely challenges of the locality where the structure is located.
One additional comment is appropriately lodged for the rib web 60 design. Because the rib web 60 maximizes contact area between the apices and the inside surfaces of the external and internal planar surfaces, it is a preferred embodiment for environments challenged with heavy weather and/or earthquakes. That additional surface area of contact between apex and inside planar surface can lend significantly added strength at those attachment sites such that the internal truss structure of the inventive panel can be maintained under the extreme conditions of wind force, projectile collisions, and/or earthquake.
