DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION

A. Insulated Concrete Form

An insulated concrete form made in accordance with the present invention may be constructed from a material such as a lightweight/low density material described below.

With reference to FIGS. 1-7, an exemplary insulated concrete form 10 has a unitary construction, including a first side wall portion 12, a second side wall portion 14, and a pillar portion 16, which extend between the two side wall portions 12, 14. The pillar portion 16 has a first tapered section 18, a second tapered section 20, and a center section 22 extending between the tapered sections 18, 20. The first tapered section 18, the second tapered section 20, and the center section 22 have an octagonal-shaped longitudinal cross-section, and are axially aligned with each other. The first tapered section 18 tapers in from the first side wall portion 12 at a 45° angle to the center section 22. The second tapered section 20 tapers in from the second side wall portion 14 at a 45° angle to the center section 22. Preferable, the first tapered section 18 is substantially complementary with the second tapered section 20 and both cooperate with the center section 22 and the side wall portions 12, 14 to define semi-octagonal voids of equilateral sides, as will be further described below.

Together, the side wall portions 12, 14 and the pillar portion 16 define a series of voids. As depicted in FIG. 2, a leftward-facing vertical semi-octagonal void 24a and a rightward-facing vertical semi-octagonal void 24b are defined by the side wall portions 12, 14 and pillar portion 16 of the form 10. As depicted in FIG. 4, an upward facing horizontal semi-octagonal void 26a and a downward-facing horizontal semi-octagonal void 26b are defined by the side wall portions 12, 14 and the pillar portion 16. These octagonal voids have equilateral sides.

As shown in FIG. 8, it is contemplated that by placing a predetermined number of forms 10 side-by-side with each other, a form 10 of a predetermined length can be formed. The forms 10 may be placed such that the right faces 28a, 28b of the side wall portions 12, 14 of a first form abut the left faces 30a, 30b of the side wall portions 12, 14 of a second form. In this manner, the rightward-facing vertical semi-octagonal void 24b of one form and the leftward-facing vertical semi-octagonal void 24a of a second form forms a complete vertical substantially octagonal void 32. Note that the octagonal void 32 tapers out at either end of the void 32 in complement with the tapered sections 18, 20 of the pillar portion 16 of each form 10. Of course, forms 10 of a desired length may be of a unitary construction, for example, by using a mold to form a form having multiple pillar portions.

Turning now to FIGS. 8-10, it is contemplated that forms 10 of a predetermined length may be stacked on top of one another to create a wall structure 100 of a predetermined height. The forms 10 may be stacked such that the top edges 34, 36 of the side wall portions 12, 14 of a lower form abut the bottom edges 38, 40 of the side wall portions 12, 14 of an upper form. When the forms 10 are stacked in this manner, the upward facing horizontal semi-octagonal void 26a of a lower form and the downward-facing horizontal semi-octagonal void 26b of an upper form form a complete horizontal substantially octagonal void 42 running the length of the forms 10. The stacked forms 10 of the wall structure 100 are oriented such that pillar portions 16 align with each other, such that continuous vertical octagonal voids 32 running the height of the wall structure 100 are created.

With reference to FIGS. 8-10, the vertical octagonal voids 32, the upward facing horizontal semi-octagonal void 26a of the upper-most form, the downward-facing horizontal semi-octagonal void 26b of the lower-most form, the horizontal octagonal voids 42, the leftward-facing vertical semi-octagonal voids 24a of the left-most forms and the rightward-facing vertical semi-octagonal voids 24b of the right-most forms created by the stacked forms 10 all interconnect to form a grid or a post-and-beam lattice of interlocking and flared octagonal voids defined by the structure 100 of the stacked forms 10.

The forms 10 are placed adjacent to each other and joined together using traditional methods known in the art. It is contemplated that the exemplary wall structure 100 is substantially rectangular in shape, but other shapes and configurations are possible without departing from the spirit and scope of the present invention.

After the plurality of forms 10 are positioned and joined together into the desired wall structure 100, the wall structure 100 can be reinforced. For example, the grid of vertical and horizontal substantially octagonal voids may be filled with a material such as reinforcing concrete and/or rebar. Of course, the leftward facing vertical semi-octagonal voids 24a of the left-most forms and the rightward-facing vertical semi-octagonal voids 24b of the right-most forms must be temporarily closed or sealed prior to filling the structure 100 with concrete to contain the concrete within the structure 100. Thus, temporary closure members 102, 104 are shown in FIGS. 8-10, with the understanding that any equivalent structure could be utilized for this purpose without departing from the scope of the teachings described herein. In this regard, the present invention includes a wall structure 100 arranged in a post-and-beam lattice of interlocking and flared octagonal voids between the pillar portions 16, whereby the voids are filled with reinforcing concrete and/or rebar, to create a wall structure 100.

The strength of the structure 100 created from the forms 10 of the present invention depends, in part, on the lattice of vertical and horizontal substantially octagonal voids 32, 42 defined by the structure of the forms, which form 450 compound angles at every intersection between vertical and horizontal voids 32, 42. Less effective insulation and finishing systems include either concrete slabs or assemblies creating cylindrical voids, which do not provide 45° compound angles at intersection between vertical and horizontal voids. The substantially octagonal voids 32, 42 created by the plurality of stacked forms 10 of the present invention, once filled with a suitable material, result in a structure that is at least 80% stronger than assemblies using cylindrical voids, and at least 60% stronger than systems using concrete slabs. The result is a tremendously strong wall system that may be designed to be capable of withstanding the lateral wind load resistance and torque that can exist in a wind storm or hurricane. Additionally, the form 10 of the present invention made from the insulated concrete material described above is substantially fireproof, bug proof, mold proof, wind proof, sound-reducing and is economical to build.

When a wall structure is created by stacking forms and filling the horizontal and vertical octagonal voids with a reinforcing material, such as concrete and/or rebar, the qualities (e.g., strength, “R” value, etc.) of the resulting wall may depend, in part, on the various dimensions of the form. For example, the distances between adjacent octagonal voids and the outer dimensions of the octagonal voids of the forms used to build the wall can be adjusted to affect the ability of the wall to withstand lateral wind load resistance and torque that could exist in a wind storm or hurricane. For another example, the width of the forms used to build the wall can be adjusted to affect the “R” value of the wall. For another example, the height and length of the wall can be adjusted to accommodate the needs of a particular building project and/or the standards in a particular market or part of the country.

An exemplary form may be provided having a height of 16 inches, a length of 96 inches, a width of 14 inches, a distance between the center of adjacent octagonal voids of 16 inches, and outer dimensions of the octagonal voids of 6 inches by 6 inches. Another exemplary form may be provided having a height of 32 inches, a length of 96 inches, a width of 14 inches, a distance between the center of the octagonal voids of 16 inches, and outer dimensions of the octagonal voids of 6 inches by 6 inches. Other exemplary forms may be scaled upward or downward in size, depending on the intended purpose. For instance, to construct a structure having a height of greater than 40 feet, it is desirable that the outer dimensions of the octagonal voids be 8 inches by 8 inches. Smaller structures may require forms having octagonal voids measuring 4 inches by 4 inches.

The above-described exemplary insulated concrete forms are examples of the insulated concrete form 10 of the present invention and other embodiments and designs may be provided without departing from the spirit and scope of the present invention. For example, in certain other embodiments, forms may be provided having a pair of side wall portions and any number of pillar portions, which wall portions and pillar portions of the forms define various substantially octagonal voids. Forms of various complementary sizes may be stacked adjacent one another to form a wall of any desired height or width, forming grids of horizontal and vertical substantially octagonal voids. Additionally, the principles taught herein may also be applied to insulated concrete forms for forming a structure having a post and beam lattice of interlocking voids that are in other, multi-faceted, non-cylindrical cross-sectional shapes, such as square or hexagonal.

B. Mold for Making Insulated Concrete Forms

As shown in FIG. 11 through FIG. 14, an exemplary embodiment of a mold 200 for forming a form as described above comprises an elongated horizontal frame 202, a first end plate 204, a second end plate 206, a first set of arms 207, 208, 209, a second set of arms 210, 211, 212, a first side plate 213, a second side plate 214, an elongated horizontal caster deck member 216, a slave pallet element 218, a first spine member 220, and a second spine member 222. The first end plate 204, second end plate 206, first side plate 213, second side plate 214, slave pallet element 218, first spine member 220 and second spine member 222 cooperate to define a mold cavity having an open top. The mold cavity is for forming an insulated concrete form as described above.

The elongated horizontal frame 202 has opposing sides and opposing ends. The elongated horizontal frame 202 serves as a base to which the end plates 204, 206, arms 207, 208, 209, 210, 211, 212, side plates 213, 214, and caster deck member 216 are connected. The elongated horizontal frame 202 of the exemplary mold 200 is supported on wheels 223 which facilitate easy movement of the assembly.

The first end plate 204 and the second end plate 206 extend upwardly, substantially vertically, along respective frame ends. The end plates 204, 206 have opposing interior sides 224, 226. In the exemplary embodiment, the first end plate 204 is fixedly attached to a frame end, and the second end plate 206 is hingedly attached to the other frame end. A first hinge 228 is shown in FIG. 12, and a second complementary hinge is concealed in the figure. Advantageously, the second end plate 206 may therefore be opened outward with respect to frame 202 and the first end plate 204 to facilitate opening of the mold 200 and removal of a insulated concrete form 299 (FIG. 13) formed therein, as described below. A handle 205 aids in this action.

The first set of arms 207, 208, 209, and the second set of arms 210, 211, 212 are slidingly attached to the frame 202 along respective sides of the frame 202. The sliding attachment allows the arms 207, 208, 209, 210, 211, 212 to extend and retract laterally from the respective sides of the frame 202, the benefit of which will be explained below. In the exemplary embodiment, the arms 207, 208, 209, 210, 211, 212 are preferably made of C-shaped track that cooperates with rollers or wheels (hidden) fixed to the frame 202 (similar to a garage door track and roller configuration) to guide the travel of the arms substantially normal to a longitudinal axis of the frame 202. A stop mechanism (not shown) is provided to prevent the arms from becoming detached from the frame 202.

The first side plate 213 is attached to distal ends of the first set of arms 207, 208, 209 along a lower portion of said first side plate 213 and extends upwardly, substantially vertically, along one side of the frame 202. The second side plate 214 is attached to distal ends of the second set of arms 210, 211, 212 and also extends upwardly, substantially vertically, along the other side of the frame 202. The side plates 213, 214 have respective opposing interior sides 230, 232. Additionally, in the exemplary embodiment 200 shown, the side plates 213, 214 have respective wheeled support legs 234a, 234b, 236a, 236b which support the weight of the side plates 213, 214 while allowing the side plates to be pulled out from or pushed in toward the frame 202. Advantageously, the side plates 213, 214 may be opened outward (or closed inward) with respect to the frame 202 and each other, guided by said arms 207, 208, 209, 210, 211, 212 in a drawer-like fashion, to facilitate opening of the mold 200 and removal of a insulated concrete form 299 (FIG. 13) formed therein, as described below. Handles 238a, 238b, 240a, 240b on the respective side plates 213, 214 aid in this action.

The elongated horizontal caster deck member 216 is positioned on the frame 202, and has an upward-facing surface 242 and a plurality of casters 244. The plurality of casters 244 are positioned on the upward-facing surface 242. Each of the plurality of casters 244 has an upward-facing, weight-bearing roller element 246 to support the slave pallet element 218 and an insulated concrete form to be formed in the exemplary mold 200. As shown in FIG. 13, the casters 244 of the exemplary mold 200 are positioned in pairs along the length of the caster deck member 216.

The slave pallet element 218 is positioned on the plurality of casters 244, and abuts a lower portion of the end plate interior sides 224, 226 and the side plate interior sides 230, 232 when the end plates 204, 206 and side plates 213, 214 are in a closed position with respect to the frame 202 and each other. Thus, the slave pallet element 218 forms the floor of the mold cavity. Additionally, the slave pallet element 218 is independent from the end plates 205, 206 and side plates 213, 214, allowing it to support an insulated concrete form that has been formed in the exemplary mold 200 to facilitate removal of the insulated concrete form from the mold 200.

The first spine member 220 is attached to the first side plate interior side 230, and the second spine member 222 is attached to the second side plate interior side 232. Each spine member 220, 222 has, respectively, a semi-octagonal base portion 248, 250, semi-octagonal end projections 252, 254, 256, 258 at each end thereof, and a plurality of octagonal post projections 260a-e, 262a-e. Additionally, a plurality of quasi-octagonal wedges 264, 266 span between the respective semi-octagonal base portions 248, 250, semi-octagonal end projections 252, 254, 256, 258, and octagonal post projections 260a-e, 262a-e. Advantageously, respective opposing semi-octagonal end projections 252, 254, 256, 258, and respective opposing octagonal post projections 260a-e, 262a-e meet when the side plates 213, 214 are in a closed position.

The exemplary mold 200 forms a block form, as described above, with the block form on its side. That is to say, the spine members 220, 222 form the flared semi-octagonal and octagonal voids of the block form, and the space in the mold cavity above and below the spine members 220, 222 forms the side walls of the block form. The opposing semi-octagonal end projections 252, 254, 256, 258, and plurality of opposing octagonal post projections 260a-e, 262a-e define the vertical semi-octagonal and octagonal voids of an insulated concrete form to be formed in the exemplary mold 200. The plurality of quasi-octagonal wedges 264, 266 serve to define, along with the semi-octagonal end projections 252, 254, 256, 258, and plurality of opposing octagonal post projections 260a-e, 262a-e, an octagonal pillar portion of such an insulated concrete form, and further define the 45 degree compound angles at every intersection between the horizontal and vertical voids of the insulated concrete form. The semi-octagonal base portions 248, 250 define upward-facing and downward-facing horizontal semi-octagonal voids of such an insulated concrete form.

One of skill in the art will recognize that the scope of the claimed mold is not limited to the described octagonal/semi-octagonal configuration of spine members 220, 222, as the principles taught herein would also apply to square, hexagonal and other such configurations. Additionally, it should be noted that the design of the exemplary mold 200 allow easy scaling up or scaling down of the insulated concrete form to be produced therein by using interchangeable, scaled up/down spine members 220, 222. Thus, insulated concrete forms having voids with outer dimensions of 8 inches by 8 inches, 6 inches by 6 inches, or 4 inches by 4 inches may be formed with the use of appropriately scaled spine members 220, 222.

Respective spacer strips 268, 270, 272, 274 are removably attached along the top edges of the end plates 204, 206 and the side plates 213, 214. The spacer strips 268, 270, 272, 274 allow additional “thickness” to be added to the side wall portion of the block form that is formed above the spine members 220, 222. Further, by removing the spacer strips 272, 274 from the top edges of the side plates 213, 214 and placing them between the frame 202 and the caster deck member 216, the “thickness” of the side wall portion of the block that is formed below the spine members 220, 222 can be reduced by raising the slave pallet element 218 toward the spine members 220, 222.

Advantageously, all of the interior surfaces of the elements that define the mold cavity of the exemplary mold 200 are coated with an epoxy rubber to facilitate release of an insulated concrete form formed in the exemplary mold 200 from the elements of the exemplary mold.

In use, the end plates 204, 206 and the side plates 213, 214 of the exemplary mold 200 are closed and the mold cavity is filled with a liquid composition to be cured into an insulated concrete form. The liquid composition is allowed to adequately cure and solidify. Then, the side plates 213, 214, along with the spine members 220, 222 are pulled horizontally outward to clear the mold cavity. The second end plate 206 is opened downward, and the slave pallet element 218, with the cured insulated concrete form 299 (FIG. 13), is rolled out from the mold cavity on the casters 244.

C. Lightweight/Low-Density Material for Making Molded Products

The present invention includes a low density/lightweight material that may be used to make insulated concrete form wall panels, lightweight decorative products and shapes such as trim, edging, decretive window trim and sills; dowels and columns; flat panels used as an exterior insulation and finish systems; and for other types of construction where a masonry product is required and strength, mass of the product, insulation, fire resistance, and/or mold resistance may be an issue.

The cement used to prepare the low density/lightweight material of the present invention may be, for example, Portland cement. The aggregate may be, for example, polystyrene, ground plastics, wood, glass or other recyclable material. The cement volume-reducing compound may be a foaming agent, for example, a plant-based foaming agent capable of creating high density foamed air bubbles. One advantageous foaming agent is sold under the trade name FOAMCELL A-100, by Goodson & Associates, Inc., of Wheat Ridge, Co. This foaming agent has an expansion of 29 to 35 times and a foam density of 1.8-2.2 lbs. cu. ft, producing 270 cu. ft. foam per gal. Alternatively, other foaming agents may be used in place of FOAMCELL A-100, which produces a high-density foam, known to one of ordinary skill in the art. Preferably, the selected foaming agent is one which will not degrade the selected aggregate. For example, if the aggregate is animal-based or composed of particular organic material, such as a polymer, the selected foaming agent should not be an animal-based material or other agent which would degraded aggregate material.

An exemplary low density/lightweight material made in accordance with the present invention includes cement, an aggregate, and a cement volume-reducing compound capable of reducing the volume of cement required to bind the all of the elements of the low density/lightweight material. The low density/lightweight material may additionally include a curing accelerator. When the material is poured into a mold to create a product, the curing accelerator will reduce the production time, i.e., it may be removed from the mold more quickly. Alternatively or additionally, the low density/lightweight material may include a liquid polymer. When the product is being used to create a product, the liquid polymer will increase the strength of and add pliability to the resulting product. Alternatively or additionally, the low density/lightweight material may include a water reducer, which reduces the amount of water required to bring the low density/lightweight material to a desired consistency for filling a mold. Additionally, when the water reducer is used, the molded product will have a lighter initial weight and will cure more quickly, i.e., less water to evaporate from the molded product. Hence, when the water reducer is used, the molded product will have a higher tensile and flexural strength sooner. As such, the final molded product is ready for use or may be transported at an earlier time point. Alternatively or additionally, the low density/lightweight material may include a mold release agent, which will minimize any tendency of the molded product to stick to the mold.

The curing accelerator that is used may be, for example, a calcium-containing curing accelerator or other suitable curing accelerator. The liquid polymer that is used may be, for example, a polyurethane-based liquid polymer or other suitable liquid polymer. The water reducer that is used may be, for example, a high-range water reducer, e.g., superplasticizers, a mid-range water reducer, or another suitable water reducer. The mold release agent that is used may be, for example, a silicone-based mold release agent or other suitable mold release agent.

The combination of the constituents which comprise the cement mixture, along with the respective ratios of those constituents results in a highly advantageous cement material for use in the present insulated concrete foam. For example, the foaming agent produces high-density foam which creates microscopic air bubbles, gaps or voids in the concrete mixture as it cures. The air bubbles account for as much as 15% of the volume of the cured mixture, thus producing a lighter material with insulating properties. Further, the gaps or voids enhance the strength of the cured material. In addition, the use of a polymer based filler provides for a less brittle concrete material.

Table 1 provides the per unit formula for an exemplary low density/lightweight material.

TABLE 1
Basic Per Unit Formula: (depending on block size)
90 to 120 pounds of Portland cement
8 lbs to 11 lbs ground polystyrene
16–18 oz plant based foaming
agent to create high density
foamed air bubbles
Cement curing accelerator
12–14 oz liquid polymer
6–8 gallons of approx. 95° F. water
Water reducer (3 to 4 oz)
Mold release agent (3 to 4 oz)

The exemplary low density/lightweight material has a mixture ratio of cement, to polymer filler to foaming agent, based on weight, of 110:11:1-1.125.

An exemplary method of making a product using the low density/lightweight material will now be described. Water is provided and heated to about 95° Fahrenheit. The cement and cement volume-reducing compound, e.g., plant-based foaming agent, are added to the heated water. If an accelerator and/or liquid polymer are being used, these compounds are also added to the heated water. If a water reducer and/or a mold release agent are being used, these compounds are also added to the heated water. The polystyrene, provided in bead form, is then added and blended until all polystyrene beads are covered. The resulting slurry is then placed into a mold of choice and cured until a resulting molded product is ready to be removed, e.g., about 1.5 hours when a curing accelerator is being used and the molded product is a form having dimensions of about 1×1.3×8 feet, which form is then allowed to air cure for about two days before being ready for use.

One of ordinary skill in the art will recognize that additional compositions and configurations are possible without departing from the teachings of the invention. This detailed description, and particularly the specific details of the exemplary embodiments disclosed, is given primarily for illustration and no unnecessary limitations are to be understood therefrom, for modifications will become evident to those skilled in the art upon reading this disclosure and may be made without departing from the spirit or scope of the claimed invention.
