Field of Invention

[0003] This invention relates to the construction of buildings from pre-fabricated components.

Background of the Invention

[0004] Currently, most houses in North America are built by hand from raw materials one piece at a time. First, a foundation usually of concrete is framed, poured, and allowed to harden. Then, a wooden frame for the above-ground structure is added by nailing one 2" x 4" stud into place at a time. A roof, exterior wall materials such as bricks and siding, insulation, plumbing, wiring, duct work, and interior drywall surfaces come next. Each piece of wood is measured, cut, and attached on site, as are pieces of many other materials such as weatherproofing, insulation, and the like. This construction by hand requires a relatively enormous amount of skilled manpower employed on the construction site, and leads to a staggering amount of material waste and significant variability in the quality, fit, and finish from one house to the next.

[0005] Constructing a house from pre-fabricated components also has been tried. But building by hand remains the norm, because the use of pre-fabricated components raises its own set of difficulties. Transporting and installing bulky components that still require customization by hand have prevented p re-fabrication from replacing building by hand in a broad manner across the house-building industry. In addition, the relatively poor structural integrity and fit and finish of certain pre-fabrication-built houses have hindered wide-spread acceptance by house-buying consumers.

[0006] The industry needs an easier way to pre-fabricate components for new houses and buildings, and to assemble those components easily. Those new houses and buildings also need a structural integrity that the public will accept.

Summary of the Invention

[0007] Unexpectedly, Applicants have invented sectional building systems, components, and methods that address certain needs of industry. In some embodiments of the present invention, sectional building components appear that are smaller than prefabricated components tried before. That smaller size facilitates transportation and construction, in some cases. In other cases, certain embodiments provide for the introduction of reinforcements that greatly enhance the structural integrity of the completed building far beyond that exhibited by buildings built by hand and required by conventional building codes. In still other cases, p re-fabrication dramatically reduces material waste, and allows for significant scrap recycling that is not feasible for scrap produced on the construction site of a building built by hand. The types of buildings that can be built in accordance with the present invention are not limited. Houses, garages, sheds,

commercial buildings, warehouses, portable or quickly-constructed buildings useful in military and disaster relief efforts, office buildings, and multi-family dwelling structures may be mentioned.

[0059] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, and some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0060] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

[0061] Where ever the phrase "for example," "such as," "including" and the like are used herein, the phrase "and without limitation" is understood to follow unless explicitly stated otherwise. Similarly "an example," "exemplary" and the like are understood to be non-limiting.

[0062] The term "substantially" allows for deviations from the descriptor that don't negatively impact the intended purpose. Descriptive terms are understood to be modified by the term "substantially" even if the word "substantially" is not explicitly recited.

[0063] The term "about" when used in connection with a numerical value refers to the actual given value, and to the approximation to such given value that would reasonably be inferred by one of ordinary skill in the art, including approximations due to the experimental and or measurement conditions for such given value.

[0064] The terms "comprising" and "including" and "having" and "involving" (and similarly "comprises", "includes," "has," and "involves") and the like are used

interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of "comprising" and is therefore interpreted to be an open term meaning "at least the following," and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, "a device having components a, b, and c" means that the device includes at least components a, b and c. Similarly, the phrase: "a method involving steps a, b, and c" means that the method includes at least steps a, b, and c. [0065] Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

[0066] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

[0067] It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

[0068] The various components of the present invention can comprise any suitable materials. Wood, wood products such as plywood and other engineered wood products such as oriented strand board, plastic, metal, cement, and composite materials such as combinations of any of the foregoing can be suitable in one or more instances. For example, oriented strand board such as those comprising alternating layers of wood particles oriented in alternating perpendicular planes and held together with a suitable amount of polymer or adhesive, can be used in some embodiments. In addition, certain instances of the present invention employ one or more types of insulation. Any suitable insulation can be used. For example, in some cases the insulation is chosen from open cell foams, closed cell foams, fibers, pellets, and combinations thereof. The insulation can be in any suitable form as well, such as, for example, nonwoven fibers, woven fibers, rolls or batts of fiber insulation such as familiar fiber glass insulation, injectable foams, pellets, nuggets, and the like can be used. Individual pieces such as pellets or nuggets can be bound or free, or a combination thereof. Binding pellets of insulation together can be accomplished by any suitable methods. Thermal treatments, adhesives, and combinations thereof may be mentioned. Water-impermeable materials also appear in further embodiments of the present invention. Any suitable water-impermeable material can be used. In some cases, a thin film of polymer such as polyethylene or polyvinyl chloride can be glued to a surface. In other cases, a polymer is sprayed, painted on, polymerized, or otherwise applied to or formed on a surface to impart water impermeability to that surface.

[0069] The various components of the present invention can be manufactured according to any suitable method. For example, the various parts of a given component can be cut or formed into their desired shape according to any suitable method. For wood- containing parts, saws, lasers, drills, routers, sanders, and the like can be directed by hand, by computer, or by a combination thereof. Plastic or metal parts can be extruded, cut, molded, milled, or otherwise shaped as desired. In addition, the various parts can be connected to each other according to any suitable means. For example, a piece of oriented strand board can be connected to another piece of oriented strand board with screws, nails, adhesive, or a combination thereof. In some cases, the various parts are engineered to fit together like the pieces of a puzzle. Any suitable technique of wood joinery can be used. Structures such as finger joints, dovetail joints, tongue and groove joints, tongue and fork joints, dowel joints, miter joints of any suitable angle, and the like can be employed.

[0070] The various components of the present invention can have any suitable dimensions. For example, in some cases, a wall panel is about 2' wide by about 6" thick by about 8' tall. Without wishing to be bound by theory, it is believed that certain embodiments of the present invention exhibit improved structural integrity over sectional components reported before, because of the smaller size of some of the embodiments of the present invention. Before, the apparent goal was to minimize installation effort by making structural insulated panels as large as possible. Those large panels were unwieldy to install, and structural support was sacrificed to reduce weight in some instances. Certain embodiments of the present invention provide handy installation by using smaller-dimensioned

components, yet structural integrity is not sacrificed, but rather enhanced, by the

dimensions of those certain embodiments. Thus, some cases provide a beam no longer than about 5 feet, no longer than about 6 feet, no longer than about 7 feet, no longer than about 8 feet, longer than about 9 feet, no longer than about 10 feet, no longer than about 15 feet, or no longer than about 20 feet. Other cases provide a wall panel, floor panel, or roof panel no wider than about 1 foot, no wider than about 2 feet, no wider than about 3 feet, no wider than about 4 feet, no wider than about 5 feet, or no wider than about 10 feet.

[0071] Various embodiments of the present invention can be used in combination with other embodiments of the present invention. For example, floor beams and beam nodes such as those described herein can be used with floor panels such as those described herein. Or, certain embodiments of the present invention can be used with suitable non-inventive materials and construction techniques. For example, inventive floor beams and beam nodes can be deployed to create a foundation, and then conventional flooring techniques and materials can be applied. In another example, inventive wall panels and ceiling panels can be combined with conventional roof infrastructure such as the ceiling beams (451 , 452) seen in Fig. 1 . [0072] Once the various components are manufactured or installed, any suitable finishing material or materials can be added. For example, once one or more wall panels have been installed, drywall, tile, trim, and combinations thereof can be added to the interior side of the wall panels, while brick, vinyl, aluminum, wood-cement composite such as HardiPlank™, and combinations thereof can be added to the exterior side of the wall panels. Any suitable utilities can be added, such as plumbing for hot and cold water and wastewater and sewage removal; electrical power cables for illumination, electrical data cables for entertainment, and fire, smoke, carbon monoxide detection, fixtures such as fans and appliances, and electrical outlets; gas lines for heating and cooking, and duct work for air handling as well as heating and cooling appliances. Windows, doors, garage doors, fireplaces, steps, stairs, closets, pantries, attic access doors, and the like can be added and finished as needed. Cabinets, counters, sinks, bathtubs, shower stalls, toilets, and the like can be added in any suitable fashion, such as, for example according to known techniques. One advantage of some embodiments of the present invention is that they are made from wood or engineered wood products: that allows the facile attachment of finishing materials such as drywall, conventional flooring such as, for example carpet, tile, hardwood, engineered hardwood, and polymer flooring, according to conventional techniques.

Detailed Description of the Drawings

[0073] Further embodiments of the present invention can be described by reference to the accompanying drawings, which are not necessarily to scale. In addition, not every element is labeled, so the figures can be viewed easily. Elements in different figures having the same label are intended to be the same element in each such figure. Fig. 1 shows, in one embodiment of the invention, the partial construction of house 10. Beams, such as beam 101 , beam 102 connected to each other by a beam node 502, and beam 106 connected to beam 107 by beam node 507, rest on a subfoundation (not shown) to form a foundation. Any suitable subfoundation can be employed, such as, for example

cinderblocks, poured cement, slab, crawlspace, a grid of helical piles such as depicted in Fig. 57, or a combination thereof. Floor panels, such as floor panel 208, are supported by and attached to beams such as beam 101 and beam 105. The beam 107 supports wall panel 621 having a window opening therein, wall panel 301 , and corner wall panel 61 1 . Shear blocks 41 b and 41 c are positioned between wall panel 301 and corner wall panel 61 1 . Without wishing to be limited by theory, it is believed that shear blocks such as shear blocks 41 b and 41 c impart superior structural integrity to house 10. Floor panel 202, and unseen beam 103 beneath floor panel 202 (see Fig. 2), supports wall panel 302. Floor panel 202 partially supports wall panel 622 having a window opening therein. Floor panel 202 partially supports wall panel 631 having a door opening therein. The wall panel 631 having a door opening therein partially supports ceiling beam 451 , which in turn supports ceiling posts 455, 456, and roof beam 462. Those components in turn support numerous roof panels. Wall panel 621 partially supports ceiling beam 452 and roof beam 461 . Roof beam 461 partially supports roof panels 401 , 402, and ridge roof panels 405, 406. Roof panels 401 , 402 engage, connect to, and support each other via shear-stabilizing coupling elements 45a, 45b. Without wishing to be bound by theory, it is believed that shear- stabilizing coupling elements such as shear-stabilizing coupling elements 45a and 45b impart superior structural integrity to house 10. Also visible is fascia 471 , which connects and supports roof panels 401 , 402. Gable wall panel 641 is visible proximal to fascia 471 and roof panel 41 1 . As mentioned before, the various components can be constructed, on the one hand, and connected together, on the other hand, through any suitable means. In addition to the coupling provided by shear-stabilizing coupling elements (for example, 45a, 45b) and shear blocks (for example, 41 b, 41 c), nails, screws, bolts, adhesive, wood joinery techniques, and combinations thereof can be employed.

[0074] Fig. 2 provides a perspective view, partially exploded, of several beams according to an embodiment of the invention, position to engage several beam nodes. Beam node 505 is positioned to align and engage beam 105 to beam 104. Beam node 504 is positioned to engage beam 104 to beam 103 at a 90° angle. Beam node 503 is positioned to engage beam 102 to beam 103 at a 90° angle. Beam node 502 is positioned to align and engage beam 102 with beam 101 . Beam node 501 is positioned to align and engage beam 101 with another beam (not shown). One end of beam 101 comprises a beam node coupling element 121 , position to engage beam coupling element 571 of beam node 502. Similarly, one end of beam 102 comprises a beam node coupling element 123, position to engage beam coupling element 572 of beam node 502. The arrow indicates the direction of movement of the beams to engage the beam nodes.

[0075] Fig. 3 shows in detail how beam 102 and beam 103 engage beam node 503. Beam 102 comprises a beam coupling element that comprises tongue 132a and groove 142a, that slidingly engage beam coupling element 573 of beam node 503. Once engaged, a screw or bolt (not shown) can secure hole 543a to hole 192a. Beam 103 comprises a beam coupling element that comprises tongue 133b and groove 143b, that slidingly engage beam coupling element 574 of beam node 503.

[0076] Figs. 4 and 5 show perspective views from outside (Fig. 4) and inside (Fig. 5) house 10. Wall panel 302 having first main surface 312 is coupled to beam 103. Wall panel 302 further comprises side member extension 352a that is adapted to transfer load to ledger 1 15 of beam 103. Wall panel 302 also has a shear block receiving port 392a positioned at a first edge of the first main surface 312, and another shear block receiving port 392e positioned at a second edge of the first main surface 312. Wall panel 303 comprises a first main surface 313 that has a shear block receiving port 393a positioned at a first edge of its first main surface 313, and another shear block receiving port 393d positioned at a second edge of its first main surface 313. When wall panel 303 is placed in its final position alongside panel 302, shear block receiving port 393d will form with shear block receiving port 392a to form a shear block receiving slot of dimensions adequate to receive a shear block (not shown). Wall panel 302 also comprises second main surface 322, roof registration tab 346, second side member 351 , and floor attachment element 362. Nails, bolts, screws, adhesive, and combinations thereof can be used to secure floor attachment element 362 to the upper surface of floor panel 202. Wall panel 303 further comprises first side member 333 proximal to the first edge of the first main surface 313, and a second main surface 323 facing the interior of house 10. The first side member 333 comprises roof registration tab 344, side member extension 353a, and floor registration tab 343. Side member extension 353a will pass through registration slot 152b on the upper horizontal support member of beam 103 to transfer load to ledger 1 15. Similarly, side member extension 352a has passed through registration slot 155b on the upper horizontal support member of beam 103 to transfer load to ledger 1 15. Beam 103 coupled to beam node 503 also support floor panel 202, which can be attached to beam 103 and beam node 503 in any suitable manner. Floor panel 202 also comprises shear-stabilizing coupling element 21 1 , adapted to engage another floor panel (not shown). As illustrated in Figs. 4 and 5, registration elements can be any suitable registration element, such as registration tabs (for example, registration tab 343), registration slots (for example, registration slots 152b, 155b, and 252), and side member extensions (for example, side member extensions 352a, 353a). Registration slot 155b is adapted to receive both the side member extension 352a of wall panel 302 and the side member extension 353b of wall panel 303. In so doing, wall panel 302 and wall panel 303 are held together in support of each other. Without wishing to be bound by theory, it is believed that allowing one registration slot to receive 2 registration tabs from adjoining panels contribute to the improved structural integrity observed in some embodiments of the present invention. Floor panel 202 comprises registration slots such as slot 252 in sufficient number to receive the corresponding registration elements of up to four wall panels, two wall panels on either side of wall panels 302, 303.

[0077] Figs. 6 and 7 show how wall panels 305, 306, and 307, together with corner wall panel 612 fit together with floor panels 203 and 204 and roof panel 412. The arrow in Fig. 6 shows how roof panel 412 would fit onto wall panels 305, 306, 307, and corner wall panel 612. Roof panel 412 has wall engagement member 415 that comprises a plurality of wall registration elements such as wall registration tabs 421 and 422, adapted to engage an upper edge of those wall panels. Shear-stabilizing coupling element 432c appears on roof panel 412, adapted to engage an adjacent roof panel (not shown). Roof registration tabs such as roof registration tabs 347, 348 on wall panel 305, and roof registration tab 349 on corner wall panel 612, are adapted to engage with wall engagement member 415. Wall panel 305 comprises a ceiling beam registration element 385, that can engage a ceiling beam (not shown). Ceiling beam registration element 385 forms part of the first side member 335 of wall panel 305, which also has second main surface 325 facing the interior of a building. Floor attachment element 365 help secure to floor panel 203 and ultimately to beam 108 coupled to beam node 508. Floor panel 203 is coupled to floor panel 204 via shear-stabilizing coupling elements 213a, 213b. Floor panel 204 comprises shear- stabilizing coupling elements 214a, 214c, adapted to couple to an adjacent floor panel (not shown). The upper surface of the floor panel 204 comprises wall registration slot 254, adapted to receive a floor registration tab (not shown) of a wall panel (also not shown) adjacent to corner wall panel 612. Floor attachment element 364b helps secure corner wall panel 612 to floor panel 203. Edge member 336 of wall panel 612 can be seen, as can shear block receiving port 394c of corner wall panel 612.

[0078] The arrow in Fig. 7 shows how wall panel 307 would slidingly engage wall registration slot 253 of the upper surface of floor panel 203 and registration slot 158 of the upper horizontal support member of beam 108. Registration tab 345a near the bottom of first side member 337a of wall panel 307 would pass through wall registration slot 253 and registration slot 158. Wall registration slot 255 also appears on the upper surface of floor panel 203. The beam 108 comprises a vertical support member 161 to which is affixed ledger 1 16. Wall panel 306 has a side member extension 356 that transfers load to ledger 1 16. The shear block receiving ports of the several wall panels aligned in final position to form shear block receiving slots. For example, wall panels 305 and 306 comprise shear block receiving ports that form shear block receiving slots 393a, 393b, 393c. Shear block receiving port 393a is adapted to receive shear block 22a; shear block receiving port 393b is adapted to receive shear block 22b; and shear block receiving port 393c is adapted to receive shear block 22c.

[0079] Shear blocks such as shear block 22a can be made out of any suitable material, such as wood, engineered wood products, metal, stone, plastic, and composite materials such as wood-cement composites. Moreover, shear blocks such as shear block 22a can be placed in shear block receiving slots such as shear block receiving slot 393a through any suitable means. For example, a shear block comprising a 3" x 3" x 1 -1 /2" block of wood or oriented strand board can be placed in a shear block receiving slot manually, and optionally with the assistance of a mallet or hammer. Friction may suffice to hold a shear block in a shear block receiving slot. Or, some instances allow for the use of adhesive, wood putty, or one or more nails or screws, or combinations thereof, to ensure the shear block remains within the shear block receiving slot. Without wishing to be bound by theory, it is believed that the shear blocks such as shear blocks 22a, 22b, 22c impart superior structural integrity to walls such as the wall comprising wall panels 305, 306.

[0080] Fig. 8 shows how, in a further embodiment, wall panels 308, 309, 310 fit together with floor panels 201 , 205, 206 and gable wall panels 651 a, 651 b. The arrow illustrates the direction in which gable wall panels 651 a, 651 b would move to engage and attach to wall panels 308, 309, 310. Similar to previously-described embodiments, wall panel 308 has a first side member 338 comprising a registration tab 342 that would pass through registration slot 256 on the upper surface of the floor panel 201 to engage a registration element of a beam (not shown). Shear block receiving ports on wall panels 308, 309, and 310 align to form shear block receiving slots 394b, 395b, which are adapted to receive shear blocks (not shown). Floor panel 201 is connected to floor panel 205 via shear-stabilizing coupling elements 212a, 212b. Gable coupling boxes 661 a, 661 b, and 651 c engage and couple to the upper edges of wall panels 308, 309, and 310, respectively. Gable wall panel 651 a can then slidingly engage gable coupling boxes 661 , 661 , 661 , which are optionally secured to gable wall panel 651 a and wall panels 308, 309, 310 with any suitable means such as screws, nails, bolts, adhesive, and combinations thereof.

Gable coupling boxes 662a, 662b, 662c in turn engage and couple to the upper edge of gable box 651 a, whereupon gable wall panel 651 b can slidably engage. Again attachment is optionally provided by any suitable means. Gable wall panel 651 b has registration tabs 655a, 655b, adapted to engage corresponding registration slots on either a further gable wall panel (not shown) or a wall engagement member of a roof panel (not shown).

[0081] Fig. 8 depicts an embodiment corresponding to that shown in Figs. 6 and 7, except that wall panel 305 in Figs. 6 and 7 is replaced by wall panel 622. As such, the embodiment shown in Fig. 9 depicts a portion of the embodiment shown in Fig. 1 . Wall panels 306, 307, corner wall panel 612, floor panels 203, 204, roof panel 412, and beam node 508 appear as in Figs. 6 and 7. Floor panel 204 is coupled to floor panel 207 via shear-stabilizing coupling element 214a; shear-stabilizing coupling element 215b emerges from an edge of the floor panel 207 ready to engage an adjacent floor panel (not shown).

[0082] Wall panel 622 comprises window opening 628 adapted to receive any suitable window frame. The window frame can be custom-built, or pre-fabricated, or a combination thereof. The window frame can be any suitable size, and additional material can be added to secure the window frame in window opening 628. Floor attachment element 363 help secure wall panel 622 to the upper surface 222 of the floor panel 203, via any suitable attachment means. Wall panel 622 comprises edge member 339 that further comprises registration tab 341 and side member extension 351 adapted to transfer load to a ledger of a beam (not shown). Wall panel 622 also comprises a ceiling beam registration slot 386, which in Fig. 1 receives and supports ceiling beam 452. The corner wall panel 612 adjoins wall panel 313, which in turn adjoins wall panel 314. Wall panels 313, 314 engage and rest upon floor panels 204, 207, respectively, and together with corner wall panel 612, couple to and support gable wall panel 642.

[0083] The vertical arrow in Fig. 9 shows the relative movement of roof panels 403, 412, and 404 to engage wall panels 622, 306, 307, corner wall panel 612, and gable wall panel 642. Roof panel 412 connects to the upper edge of those wall panels via wall engagement member 415, as explained above. Roof panel 403 engages roof panel 412 via shear-stabilizing coupling element 432a, among others, while roof panel 412 engages roof panel 404 via shear-stabilizing coupling element 433a among others. Roof panel 404 further comprises shear-stabilizing coupling element 434a and wall registration element 423, which is adapted to engage the top edge of gable wall panel 642. The diagonal arrow in Fig. 9 shows the relevant movement of fascia 472 to engage and connect to roof panels 403, 412, and 404.

A. Beams and Beam Nodes [0084] As stated above, some embodiments of the present invention relate to beams useful in sectional construction comprising: one or more vertical support members supporting and separating an upper horizontal support member and a lower horizontal support member; and at least one ledger adapted to support a vertical load. As can be appreciated, "upper," "lower," "horizontal," and "vertical" as used throughout this application are purely relative terms to aid the understanding of the invention, and are not to be construed strictly. In some instances, a beam can be rotated along its main axis by 90°, and its "vertical" support members are now horizontal.

[0085] Figs. 10-13 and 144 relate to a beam 103 useful in sectional construction. Fig. 10 provides a perspective view; Fig. 1 1 provides a right side elevation view; Fig. 12 provides an end-on elevation view; Fig. 13 provides a top-down plan view. The right side elevation view in Fig. 1 1 is identical to the left side elevation view; the end on view of Fig. 12 is identical to the view from the other end. Fig. 144 shows a bottom-up plan view of beam 103. Those figures depict a beam 103 useful in sectional construction comprising: a first vertical support member 162 and a second vertical support member 163 that together support and separate an upper horizontal support member 173 and

a lower horizontal support member 174. A first ledger 1 15 adapted to support a vertical load is affixed to a vertical face of the first vertical support member 162. A second ledger 1 17 adapted to support a vertical load is affixed to a vertical face of the second vertical support member 163. The beam 103 has a first end 181 and a second end 182. First end 181 comprises a beam node coupling element that comprises tongue 134b and groove 144b. Groove 144b further comprises holes 193a, 193b that are adapted to each receive a screw, bolt, nail, rivet, or other suitable fastener to secure the first end 181 to the

corresponding structure of a beam coupling element on a beam node (not shown). Second end 182 comprises a beam node coupling element that comprises tongue 133b and groove 143b. Groove 143b further comprises holes 194a, 194b that are adapted to each receive a screw, bolt, nail, rivet, or other suitable fastener to secure the second end 182 to the corresponding structure of a beam coupling element on a beam node (not shown - see Fig. 3). Registration elements that are registration slots 152a, 152b, 155a, 155b, 159a have been cut into upper vertical support member 173, and are adapted to receive registration tabs and side member extensions of up to four wall panels (not shown - see, for example, Fig. 7). Beam 103 is suitable for use in any useful orientation, such as, horizontal, vertical, or at a diagonal, such as to support a roof. Accordingly, registration slots 152a, 152b, 155a, 155b, 159a are adapted to receive at least one corresponding registration element of a floor panel, wall panel, ceiling panel, or a combination thereof. Beam 103 can be made of any suitable material. In some cases, beam 103 comprises an engineered wood product. In further cases, the engineered wood product comprises oriented strand board. Beam 103, in still further cases, can comprise insulation. For example, before or after installation, beam 103 can receive insulation in any suitable form adhered to one or more surfaces of the beam 103 by any suitable means, such as, for example, adhesive, staples, tacks, nails, and combinations thereof. In some instances, the insulation comprises a spray-on foam insulation. Any suitable number of registration elements can appear on beam 103. Further instances provide registration elements in sufficient number to receive the corresponding registration elements of at least two wall panels, of at least three wall panels, or of at least four wall panels.

[0086] Figs. 14-19 and 59-66 depict several embodiments of beam nodes in various views. Fig. 14 provides a perspective view of linear two-way beam node 502. Fig. 59 provides a bottom-up plan view from the direction of arrow D in Fig. 14, while Fig. 60 illustrates a right-side elevation view from the direction of arrow C in Fig. 14. The right-side elevation view is identical to the left-side elevation view. Fig. 61 provides a front elevation view from the direction of arrow B in Fig. 14. The back elevation view is identical to the front elevation view. Fig. 62 provides a top-down plan view of beam node 502 from the direction of arrow A in Fig. 14. Fig. 15 provides a perspective view of a 90-degree two-way beam node 509. Fig. 16 provides a right side elevation view of beam node 509 as seen from the direction of arrow C in Fig. 15. Fig. 17 provides a top-down plan view of beam node 509 as seen from the direction of arrow A in Fig. 15. Fig. 63 provides a left side elevation view of beam node 509 as seen from the direction of arrow F in Fig. 15. Fig. 64 provides a back elevation view from the direction of arrow E in Fig. 15. Fig. 65 provides a front elevation view from the direction of arrow B in Fig. 15. Fig. 66 provides a bottom-up plan view of beam node 509 from the direction of arrow D in Fig. 15. Fig. 18 provides a perspective view of a three-way beam node 503, while Fig. 19 shows a top-down plan view of beam node 503, as seen from the direction of arrow A in Fig. 18. Fig. 67 shows a right side elevation view of beam node 503 from the direction of arrow E in Fig. 18, while Fig. 68 shows a left side elevation view from the direction of arrow B. Fig. 69 shows a front elevation view from the direction of arrow C, while Fig. 70 shows a back elevation view from the direction of arrow F in Fig. 18. Fig. 71 shows a bottom-up plan view from the direction of arrow D in Fig. 18. [0087] In Figs. 14 and 59-62, beam node 502 has a lower horizontal support member 512 that supports first vertical support member 515a and second vertical support member 515b. Vertical support members 515a, 515b define a first beam coupling element 571 and a second beam coupling element 572. The second beam coupling element comprises tongues 522a, 522b, that are adapted to fit into a corresponding groove of a beam node coupling element of a beam (not shown). As can be appreciated from Fig. 14, first beam coupling element 571 is adapted to couple a first beam (not shown) in line with a second beam (also not shown) coupled to the second beam coupling element 572. First beam coupling element 571 also includes holes 542a, 542b that allow a bolt or other suitable connector to secure beam node 502 to a beam (not shown). Beam node 502 further comprises two substantially parallel vertical supports 555a, 555b separated by a spacer element 563, thereby defining two registration elements that are two registration element receivers 532a, 532b between the two substantially parallel vertical supports 555a, 555b. The registration element receivers 532a, 532b are adapted to receive the corresponding registration tabs and side member extensions of one or two wall panels (not shown). So, for example, looking at Fig. 1 , wall panel 621 and its beam node registration tab and side member extension (not clearly seen in Fig. 1 ) would share registration element receivers of beam node 507 with an adjacent wall panel (not shown in Fig. 1 ). By sharing registration element receivers, wall panels are stably connected and supported, in some embodiments of the present invention. Without wishing to be bound by theory, it is believed that the connection and support provided when two registration tabs share the same registration slot contribute to the improved structural integrity exhibited by some embodiments of the present invention.

[0088] Figs. 15-17 and 63-66 show beam node 509 wherein first beam coupling element 575 is adapted to couple a first beam (not shown) perpendicular to a second beam (not shown) coupled to the second beam coupling element 576. Lower horizontal support member 513 supports first vertical support member 516a, second vertical support member 516b, third vertical support member 517a and fourth vertical support member 517b. first beam coupling element 575 comprises tongue 523b that is adapted to slidingly engage a corresponding groove of a beam node coupling element of a beam (not shown). Second beam coupling element 576 comprises tongue 524b that is adapted to slidingly engage a corresponding groove of a beam node coupling element of a beam (not shown). First beam coupling element 575 further comprises holes 549a, 549b each adapted to receive a bolt or other connector to secure corresponding holes on a beam node coupling element of a beam (not shown). Second beam coupling element 576 further comprises holes 549c, 549d each adapted to receive a bolt or other connector to secure corresponding holes on a beam node coupling element of a beam (not shown). The beam node 509 further comprises two substantially parallel vertical supports 556a, 556b separated by a spacer element 564, thereby defining two registration element receivers 533a, 533b between vertical supports 556a, 556b. Registration element receivers 533a, 533b are adapted to receive the corresponding registration elements of a corner wall panel.

[0089] Figs. 18, 19, and 67-71 show beam node 503 comprising a first beam coupling element 574, a second beam coupling element 577, and a third beam coupling element 573. First beam coupling element 574 is adapted to couple a first beam (not shown) in line with a second beam (not shown) coupled to the second beam coupling element 577. Third beam coupling element 573 is adapted to couple a third beam (not shown) perpendicular to the first beam and second beam. Lower horizontal support member 514 supports vertical support members 518a, 518b, vertical support members 519a, 519b, and vertical support members 520a, 520b. First beam coupling element 574 comprises tongue 525b that is adapted to slidingly engage a corresponding groove on a beam node coupling element of a first beam (not shown). Second beam coupling element 577 comprises tongue 527b that is adapted to slidingly engage a corresponding groove on a beam node coupling element of a second beam (not shown).

Upper surface 228 is adapted to serve as a floor surface or floor subsurface. Optionally, the floor panel 208 comprises insulation, affixed to any surface, within the interior volume, or a combination thereof. Any suitable insulation can be used. In some cases, the insulation is of a type that is suitable to be blown or injected through insulation injection ports 298a, 298b that are found in edge members 248a, 248b, respectively.

E. Subfoundation and Floor

[00119] Fig. 57 depicts a perspective view from above of another embodiment, namely, a plurality of beams (such as 101 , 102,) connected by beam nodes (such as 502) attached to helical piles (such as 1017, 1024). Fig. 58 depicts a perspective view from below of a portion of the embodiment shown in Fig. 57. In addition, floor panels (such as 201 , 209, 210) have been added. A grid of any suitable supports such as, for example cement-supported posts, cinderblocks, timber piles, or helical piles driven into soil, compacted soil, wet or setting cement, bedrock, or other suitable substrate can be used to form a subfoundation. In Fig. 57, 28 helical piles such as helical piles 1001 , 1002, 1003, 1007, 1008, 1009, 1010, 1014, 1017, and 1024 have been driven into soil under an applied pressure, and only the portion of the piles remaining of above ground is depicted in Fig. 57. Any suitable applied pressure can be used. For example, a downward pressure on the order of 10.1 Kips (5.05 Tons) up to 1 1 .6 Kips (5.8 Tons) can be applied to a helical pile being rotatably driven into undisturbed soil, in some cases. To those helical piles are attached beam nodes such as beam node 502, 507. To those beam nodes, beams such as beams 101 , 102, 105, 106, 107, have been attached. The beams and beam nodes in Fig. 58 have floor panels such as floor panels 201 , 209, 210 installed thereon. Further discussion of Figs. 57 and 58 appear in the examples below.

Examples

Example 1 - Performance of Beams and Floor Panels

[00120] Six helical piles having a 2 - 7/8" tubular shaft manufactured by Goliath Tech were obtained. The helical piles were driven into soil in two rows of three piles each, with 18" of the T long pile remaining above ground, and each pile being 7'-8" apart from its neighbor. Each pile was installed with a high torque drill attachment on a Kubota KX057-4 Compact Excavator. Downward pressure on the order of 10.1 Kips (5.05 Tons) up to 1 1 .6 Kips (5.8 Tons) was applied by the excavator during pile insulation to avoid plowing the soil. A 5" x 5" steel plate capped each pile, to which beam nodes similar to three-way beam node 503 and two-way beam node 509 were affixed with structural wood screws through four holes in the plate. Seven beams similar to floor beams 102 and 103 were coupled to the nodes by engaging the beam node coupling elements at each end of a beam, and screws secured the beams to the nodes, such as by securing hole 543a to hole 192a in Fig. 3. Two perimeter floor panels similar to floor panels 202 and 203 were installed end-to-end over two beams and three piles, and six floor panels similar to floor panel 208 spanned the remaining distance to the second row of three piles supporting beams. A near end of a beam was secured to a node and pile; floor panels were joined together by engaging the shear-stabilizing coupling elements of one floor panel to the ribs of the neighboring floor panel; then a far end of a beam was secured to the next node and pile. Upper surfaces of floor panels were screwed to floor beams every 4" where they overlapped. [00121] To test the shear strength of the eight-panel floor, a 3/8" heavy chain was passed through the perimeter floor panels end-to-end, and secured to a 6" x 6" steel plate over a 2-ply 3/4" Advantech 24" x 8" board to form a pressure plate. Using Figs. 57 and 58 to illustrate the eight-panel floor, the chain would have passed through floor panels 210 and 209 parallel to beam 107, with the pressure plate near pile 1003 and the chain exiting floor panel 209 near pile 1001 . Table 1 correlates the six piles of the test floor to the piles identified in Fig. 58, to further illustrate the test floor.

Table 1

A Dillon Mechanical Dynamometer connected the chain to the Excavator, to apply a tension load simulating a base shear from wind or seismic loading.

[00122] The excavator applied a load, and the deflection of each pile was measured at the top of each pile under load. The results appear in Table 2.

Table 2

[00123] After the initial round of incremental load testing, the residual deformation was measured with no load applied. Then, a first cyclic loading of four cycles of 5,000 lbs and release were applied, and residual deformation measured with no load applied. A second cyclic loading of five cycles of 5,000 lbs and release were applied, and residual deformation was measured with no load applied. These residual deformation results appear in Table 3.

Table 3

[00124] The dynamometer has a maximum capacity of 5,000 lbs, but the excavator is rated in excess of 10,000 lbs, perhaps approximately 12,000 lbs. This maximum load was applied five times to seek the weakest components of the test floor. Extreme deflections of the piles were observed, including deflection in excess of 3-1/2" for pile 1 . After five cycles of maximum load and release, each pile returned to its maximum deflection shown in Table 3. No buckling or failure was observed or found in any of the floor beam or floor panel members or connections, nor was any audible cracking or shearing of the glue-joint panel and beam connections noted during the maximum load testing.

[00125] After the foregoing tests, the test floor was disassembled and a 5,000 lbs load was applied to pile 5 in the same direction as the previous loads. At 5,000 lbs, pile 5 deflected laterally 1 -5/16".

[00126] The International Building Code (2012) recommends a maximum allowable load of one-half of the load causing a 1 " lateral deflection. From the foregoing tests, it is estimated that the lateral allowable design value is 2,000 lbs at 18" above grade. That far exceeds the expected shear load presented by a 149 mph Category 5 hurricane-force wind having a wind pressure of 29.7 PSF. Distributed over the 28 piles of Fig. 57, that equates to a load of about 350 lbs per pile.

Example 2 - Performance of a Completed Home

[00127] A home is constructed on 28 helical piles as shown in Fig. 57, and completed in accordance with Fig. 1 . A chain connected to a pressure plate affixed to the interior side of wall panel 301 is passed through wall panel 301 to a dynamometer and excavator as described in Example 1 . A tension load is applied as in Example 1 . The home is expected to sustain a load far exceeding that delivered by a Category 5 hurricane-force wind with minimal lateral deflection and no buckling or failure in any of the components or

connections, nor any audible cracking or shearing of those components and connections.
