Multi-purpose hexagonal building module
BACKGROUND OF THE INVENTION 
     This invention relates to modular structures, and more particularly to hexagonal building modules which are easily assembled of relatively low cost materials and adaptable for a wide variety of uses including living units, work spaces, equipment enclosures and containers for shipping or storage. 
     The need for low cost easily transported and readily assembled structures has been a known consideration for many, many years. Such is useful in providing housing and ancillary facilities in timely response to major migrations of people. Whether these needs are caused by political, economic or climatic changes, by wars or revolutions, by natural disasters, or by innate inclinations to seek a better life in another place, the availability of safe and sanitary housing remains the most persistent of unmet human needs (a crisis now compounded by global population growth of 92 million people a year). Even in the relative affluence of suburban USA, the shortage of storage space is pervasive, and an extra bathroom may often save a marriage. Diverse groups such as armed forces, prisoners, construction crews, miners, field hands, loggers, cinematographic crews and geophysical scientists must be sheltered and sustained, often in remote and hostile environments, and often without recourse to conventional construction methods. 
     While modular building units are well known, those that have existed have not been entirely satisfactory for the above-described purposes. For example, components used to construct the individual modules have often required many specialized parts, such as specialized wall constructions, corner constructions, etc. Often, specialized machinery or tooling is required to construct them. In many cases, the components are heavy, bulky, and uneconomical to erect, and do not store compactly for shipment in unassembled form. A further disadvantage of known building modules is that they do not exhibit substantial strength against a wide variety of loads including vertical, horizontal and torsional loads. Many make no provisions for thermal insulation when required. A further disadvantage of existing building modules is that they lack a high degree of flexibility in terms of the various applications and functions for which they can be used or are suited. 
     Accordingly, it has been an objective of this invention to provide a building module which obviates the aforedescribed disadvantages of known modular building constructions. This objective has been accomplished in accordance with certain of the principles of this invention by providing a building module which is of hexagonal tubular configuration and preferably provided with hexagonal planar panels at opposite ends. In one preferred embodiment of the invention, the six generally planar walls of the hexagonal tubular building module are integral, the module being formed by spirally wrapping and gluing, in slightly overlapping relation, multiple plies of wood or fibrous composite veneers around a rotating hexagonal cross-section mandrel. The same result can be achieved through convolute wrapping of the plies instead of spiral wrapping. In either case, the mandrel configuration is slightly rounded along the six axially parallel edges to provide a slightly rounded shape to the six corners of the module which otherwise consists of six planar rectangular walls. Adhesive is provided between the wood or fibrous composite veneer plies of the the hexagonal tubular building module to provide a rigid construction which retains its hexagonal shape. In another embodiment of the invention, the hexagonal tubular building module is constructed of six substantially identical individual panels which are interconnected in the desired hexagonal configuration by lapped joints provided by cooperating internal and external rabbets along the vertical edges of adjacent panels. The individual panels each include a relatively large rectangular flat section and a relatively small smoothly curved section along each of two parallel edges. When the panels are hexagonally arranged and interconnected along their curved edges by lap joints, the flat sections of the panels constitute the planar walls of the hexagonal building module while the smoothly curved edge sections of the panels constitute rounded corners of the module. The lap joints between adjacent panels, which are preferably located in the centers of the rounded corners, are each constituted by an internal rabbet formed along the edge of one of the panels and an external rabbet formed along the confronting edge of the next panel. In a preferred form, the rabbetted edges of the panels are provided with aligned holes to facilitate convenient interconnection with rivets or other fasteners when the panels are lapped along their edges to form an hexagonal module. 
     Preferably, the hexagonal building module is provided with an end wall of hexagonal configuration at each end. The end panels are provided on their opposite faces with a liquid-impervious membrane. The membranes are hexagonal and slightly larger than the end panels to provide margins which extend beyond the edge of end panels. Both membrane margins are folded inwardly with the outer margin extending over the edge of the hexagonal tubular wall section, as well as around a marginal outer portion of the hexagonal tubular wall section adjacent to the edge. The inner and outer membrane margins intimately contact the inner and outer marginal portions of the hexagonal tubular wall section adjacent to the edge. The margin of the outer membrane is larger than that of the inner membrane to enable the edges of the respective membranes to lie in substantially the same plane when they are folded. Collectively, when cemented and sealed with appropriate sealant, the outer and inner membrane margins provide a strong and liquid-impervious seal at the joint formed by the end panels and the tubular wall section. 
     The hexagonal building modules of this invention, whether of integral construction or interconnected panel construction, exhibit a very high degree of strength against horizontal, vertical, and torsional loading, and do so with a minimum of bulk and weight. The modules can be compactly nested in honeycomb fashion, if desired, or horizontally spaced with their central symmetrical axis disposed vertically in an array of any desired configuration, with the spaced modules interconnected by flat filler panels, providing enormous flexibility in building design. Windows and/or doors can be provided in the panels 1where desired for light or ingress/egress. The hexagonal modules can also be stacked vertically to form a multi-level building with floors and roofs spanning between and supported by modules where desired. When needed, spiral stairways or elevators can be located within two or more of the modules to provide access to the different levels of the stacked array. 
     The individual panels which are used in constructing the fabricated panel hexagonal module, stack very compactly in nesting relationship for shipping. Once at the building site, the individual panels can be readily erected and secured in lapped relation to construct the hexagonal building module. Preferably, the panels are fabricated of wood or composite veneers, with 4&#39;×8&#39;×3/4&#34; sheets being the desired dimensions from the standpoint of convenience in shipping, handling, erection and initial fabrication. Panels of these dimensions provide a fabricated panel module having a diameter and axial dimension which are each approximately 8&#39;. Of course, other sheet materials and dimensions may be used. In the integral mandrel-wound tubular construction, the walls can be thinner and are preferably 1/2&#34; thick and the six integral rectangular side walls each approximately 4&#39;×8&#39; in size, providing for the entire module a diameter and axial dimension of approximately 8&#39; each. 
     The hexagonal modules can be equipped for a wide variety of uses including bathroom, bedroom, store room, closet, kitchen, latrine, work spaces, stairs and the like. As appropriate to interior use and desired appearance, each module can be fitted with doors, windows, louvers or hatches in a large selection, shapes and styles. The building modules are susceptive of use with a wide range of roof constructions to provide a variety of different building appearances. Roof constructions can be provided with gutters and down spouts to facilitate convenient draining of precipitation, and with ventilation systems and skylights, as desired. Further, a variety of foundation schemes can be employed to secure the module to the ground or other support surface. 
     If desired, flat panels of rigid insulation can be provided on the exterior walls of the building modules, and the walls clad in exterior finish sheathing to enhance the appearance of the module and protect the insulation against weather. Wood, metal, masonry veneer and many versions of a type of cladding, known as E.I.F.S. (Exterior Insulation and Finishing Systems) are currently used in the construction industry. 
     The hexagonal building module can be arranged with its central symmetrical axis disposed vertically or horizontally, and can be mounted at one site on temporary or permanent foundations; or can be placed on a vehicle, ship, or plane for transportation as desired. When sealed and finished for the purpose, the modules can be linked together, floated and towed to their destination on the waterways of the world. In either orientation, and whether permanently located or mobile, the module can be used for equipment housing, storage, a work space, or as a living unit.

     With reference to FIGS. 2A and 2B, FIG. 3, FIG. 4 and FIG. 5, a preferred embodiment of the tubular wall section XW of the hexagonal building module X of this invention is seen to include six panels XWA of a novel and unobvious construction to be described in more detail hereafter. Panels XWA are substantially rectangular, having a rectangular flat section XWA&#39; bordered by smoothly rounded one-half corner sections XD-1 and XD-2 and by rabbeted edges XD-11 &amp; XD-12 on opposite vertical sides thereof. The panels XWA are connected to each other along their vertical edges at lap joints XD-4. Thus, the fabricated panel hexagonal building module wall section XW consists of six substantially flat rectangular sections XWA between which are located rounded corner sections formed by lapped one-half corners XD-1 and XD-2. Suitable fasteners XD-3&#39;, such as pop rivets or threaded fasteners, secure the lapped edges XD-11 and XD-12 of adjacent panels XWA to maintain the six wall panels in the hexagonal configuration shown in FIG. 1. Preferably, the module also includes flat hexagonal end caps XE which are secured to the upper and lower horizontal edges of the panels XWA by suitable means to be described hereafter. 
     With reference to FIG. 2B and FIG. 2A, which is a perspective view of one of the building panels XWA, the panel XWA is seen to include a first or outer surface or face XD-5 and a second or inner surface or face XD-6. The panel XWA is generally rectangular consisting of an upper edge XD-7 and a lower edge XD-8 which are substantially parallel to each other. Extending between the upper edge XD-7 and lower edge XD-8 are parallel vertical edges XD-9 and XD-10. The vertical edges XD-9 and XD-10 are substantially perpendicular to the upper and lower horizontal edges XD-7 and XD-8. The panel XWA consists of a rectangular section XWA&#39; which is substantially flat, integral and contiguous smoothly curved sections XD-1 and XD-2, and integral and continuous curved inside and outside rabbeted sections XD-11 &amp; XD-12. Curved section XD-1 terminates at its left (as viewed in FIG. 2) edge in an internal rabbet XD-11, while rounded panel section XD-2 terminates at its right (as viewed in FIG. 2) edge in an external rabbet XD-12. Internal rabbet XD-11 proximate the left vertical edge XD-9 includes a shoulder and a face which runs substantially along the entire length of the edge XD-9. The rabbet face is parallel to the inner and outer surfaces or faces XD-5 and XD-6. The depth of the shoulder is approximately one-half the thickness t of the substantially flat section XWA&#39;; and curved corner XD-1 and XD-2 of the panel XWA. The external rabbet XD-12 consists of a shoulder which runs along the length of the corner section XD-2 and a face which runs along the length of the rounded one-half corner section. The shoulder is perpendicular to the outer face XD-5 and inner face XD-6 of the rounded one-half corner section XD-2 at the point where it intersects the outer face XD-7. The face of the external rabbet XD-12 is perpendicular to the shoulder and generally parallel to the outer face XD-5 and inner face XD-6 in the region of the marginal vertical edge XD-10 of the panel XWA. The thickness of the shoulder of rabbet XD-12 is equal to the thickness of the shoulder of rabbet XD-11. Similarly, the widths of the faces of internal rabbet XD-11 and of external rabbet XD-12, measured in a horizontal direction, are equal. 
     As is apparent from FIG. 3, the edge of the substantially flat section XWA&#39; and the edge of the smoothly curving section XD-2, which meet at an imaginary vertical line L-1 are integral with each other. Similarly, the edge of rectangular section XWA&#39; of panel XWA and its associated edge of one-half corner section XD-1 meet at an imaginary line L-2. The rounded corner section collectively defined by rounded corner sections XD-1 and XD-2 and lap joints XD-4 subtends in an angle of approximately 60°. As shown in FIG. 4A and the corner detail of FIG. 3, the panel XWA comprises a flat rectangular section XWA&#39; bordered on each side with a smoothly rounded curved section. The left curved section (FIG. 4A) is identified as XD-2 plus rabbet XD-12, while the right curved section is identified as XD-1 plus rabbet XD-11. As shown in FIG. 4A, a subtended arc of 30° is provided for the corner between a) the center of the rabbet XD-12 and b) an imaginary line L-1 at the junction of curved section XD-2 and the flat panel section XWA&#39;. Similarly, a subtended arc of 30° is provided for the corner between a) the center of the rabbet XD-11 and b)an imaginary line L-2 at the junction of curved section XD-1 and the flat panel section XWA&#39;. Referring to the detail of the corner shown in FIG. 3, the lap joint XD-4 is clearly shown as established by the overlapped rabbets of adjacent panels. In the preferred embodiment, the overall length of the panel measured between the upper and lower edges XD-7 and XD-8 is eight feet, while the overall width measured in the horizontal direction between the vertical edges XD-9 and XD-10 is four feet, enabling the panel XWA to be fabricated in a similar manner as commercially available four foot by eight foot sheet material, preferably seven-ply plywood. In the preferred embodiment, the thickness t of the panel XWA is approximately three-quarters of an inch. 
     Through holes XD-3 in spaced vertical alignment, preferably on four inch centers, are provided in internal and external rabbets XD-11 and XD-12 passing entirely through their respective faces. Preferably, the through holes XD-3 are placed centrally in each rabbet between the shoulder and the outer edge of the panel. The vertical elevations of the through holes XD-3 on each rabbet section XD-11 and XD-12 correspond such that when adjacent panels XWA are formed into lap joint XD-4, the holes XD-3 proximate the right vertical edge XD-10 of one panel will be in alignment with the holes XD-3 proximate the left edge XD-9 of the adjacent panel, with the shoulder of the external rabbet XD-11 of the one panel being in snug engagement with the outer edge of the internal rabbet XD-12 of the adjacent panel and face of the external rabbet of the one panel in snug engagement with the face of the internal rabbet of the adjacent panel. With the holes XD-3 of adjacent panels so aligned, when a lap, joint XD-4 is formed in the manner indicated, suitable fasteners XD-3&#39; such as pop rivets, threaded fasteners or the like, will easily pass through the aligned holes associated with the cooperating inner and outer rabbets of the adjacent panels, enabling the right edge XD-10 of one panel to be securely and conveniently fastened to the left edge XD-9 of the adjacent panel. For a permanent assembly this lap joint will also be glued as well as riveted. 
     If desired, the rabbet XD-11 associated with the outer vertical edge XD-9 of the corner section XD-1 could be an internal rabbet and the rabbet XD-12 associated with the outer edge XD-10 could be an external rabbet. Regardless of which edge has the internal rabbet and which has the external rabbet, the resulting lap joint XD-4 between adjacent panels is structurally identical. 
     In the preferred form of the invention wherein the length and width of the panels XWA are eight feet and four feet respectively, the width of the lap joint between the adjacent panels is approximately one and one-half inches. 
     FIG. 4A depicts the relationship, with respect to the corners of the fabricated panel hexagonal module XW, the orientation of the external rabbet XD-12 and internal rabbet XD-11 of the panel XWA for panels of the type depicted in FIGS. 2 and 3. In accordance with a modified form of the panel of this invention depicted in FIG. 4B, the 60° curvature collectively provided by adjacent curved sections XD-1 and XD-2 and lapped rabbet sections of the module XW can be located solely along one vertical edge of the panel XWB, such as along edge XD-10, as shown in FIG. 4B. When this is done, the panel XWB is seen to include a planar flat section XWB&#39;, a smoothly curved section XD-2&#39; which subtends an angle of 60°. The curved section XD-2&#39; has extending from its left edge as seen in FIG. 4B, the external rabbet XD-12. Constituting the right of the rectangular panel XWB is the internal rabbet XD-11. 
     With reference to FIG. 4C the upper and lower hexagonal end caps or panels XE are seen to each include an outer liquid-impervious membrane XE-1 and an inner liquid-impervious membrane XE-2. The outer and inner membranes XE-1 and XE-2 are each generally hexagonal in shape with the outer membrane being slightly larger than the inner membrane for reasons to become apparent hereafter. The outer marginal region XE-1&#39; is folded inwardly such that it extends over the upper edge XD-7 of the wall panels XW of the module X as well as around a portion of the panels XWA of the module XW adjacent the upper edge XD-7. The outer marginal XE-1&#39; of the outer membrane XE of the lower ended cap is similarly turned inwardly to snugly embrace the lower edge XD-8 of the wall panels XWA of the module XW and a portion of the lower outer face XD-5 of the panels XWA adjacent the lower edge XD-8. The marginal edge XE-2&#39; of the inner membrane XE-2 associated with both the upper end cap XE and the lower end cap XE is turned inwardly to snugly embrace portions of the inner surface XD-6 of the panels XWA constituting module wall XW approximate the edges of the upper and lower end caps XE. The edges of the outer and inner membranes XE-1 and XE-2 are located in approximately the same horizontal plane. The membranes XE-1 and XE-2 can be fabricated of a variety of liquid-impervious materials including cast, vacuum formed or blow molded fiber-reinforced resin composites. The membranes XE-1 and XE-2 can be secured to the end caps XE using suitable adhesives, and their outer margins XE-1&#39; and XE-2&#39; may be secured to the wall panels XWA of module X in a similar manner using adhesives, thereby providing a strong and liquid-impervious seal at the joint defined by the peripheral edge of the end caps XE and the upper and lower edges of the wall panels XW of module X. 
     The wall XW of the hexagonal building module X depicted in FIG. 1, in addition to being fabricated of individual panels XWA or XWE as described in connection with FIGS. 2, 3, 4 and 5, can also be fabricated as an integral or unitary hexagonally shaped tube XWC as shown in FIG. 7 of multiple overlapping spirally wound plies or lamination layers XL-1 through XL-7 using the machine of FIGS. 6A and 6B. The hexagonal building module X shown in FIG. 7 incorporating an integral hexagonal tubular wall module XWC, like the fabricated panel wall module XW shown in FIG. 5 which is fabricated of individual panels XWA, is provided with upper and lower end caps XE having outer and inner membranes XE-1 and XE-2 constructed as discussed in connection with FIG. 4C. 
     As shown in FIGS. 6A and 6B, the machine for fabricating the integral or unitary hexagonal wall XWC includes a mandrel XM-1, generally hexagonal in vertical cross-section, which is mounted for rotation about a horizontal axis onto a fixed shaft XM-2 which is cantilevered from spaced base supports XM-3. The mandrel XM-1 is formed of seven horizontal pipes XM-1&#39;, one at the core and six circumferentially spaced at equal radial distances from the core which snugly fits and rotates about shaft XM-2. The pipes XM-1&#39;, which define the corners of the hexagonal wall module XWC, are parallel to each other as well as parallel to the shaft XM-2 and are maintained in this position by radially extending spokes XM-1&#34; located at opposite ends of the mandrel XM-1. Thus, there are six spokes XM-1&#34; at each end of the mandrel XM-1 which supports the six horizontal pipes XM-1&#39; which in turn support the six flat surfaces XM-1&#34; of the mandrel which are faired to and tangent with the curved surfaces of the pipes MX-1&#39; which form the corners of the hexagonal module wall XWC. 
     Seven layers or plies of lamination material, preferably ribbons of fabric reinforced wood veneer or of fibrous composite material made for this use, are fed to the mandrel XM-1 in overlapping configuration at a slight angle to a plane perpendicular to the length of the mandrel sufficient to spirally wind the laminations XL-1 through XL-7 when the mandrel is rotated in a manner to be described. The laminations XL-1 through XL-7 are successively fed through a glue rack XM-7 which supports and contains a set of horizontally disposed vertically superimposed guide rulers XM-8 and a set of horizontally disposed vertically superimposed glue rollers XM-10. Associated with each glue roller XM-10, is an underlying glue trough XM-9. As the the glue rollers XM-10 rotate about their respective horizontal axis, the surface thereof picks up glue from its associated trough XM-9 and in turn applies glue to the bottom surface of the laminations XL-1 through XL-7 as they pass in contact with the upper portion of the glue rollers XM-10. 
     A lubricant applicator XM-11 located below the lowermost ply XL-1 applies a lubricant to the underside of lamination XL-1 assisting the spirally wound tube being formed on the mandrel XM-1 to advance longitudinally over the mandrel in a rightwardly direction as viewed in FIG. 6A. If needed to further assist this longitudinal advance of the tube, the tube-forming surfaces of the mandrel XM-1 can be perforated, the ends of the entire mandrel can be capped and pressurized air introduced into the mandrel interior to create air-layer lubrication between the mandrel and the hexagonal module wall as it is being wound on the mandrel. 
     The mandrel XM-1 with the spirally wound laminations XL-1 through XL-7 laminations thereon is rotated by an endless drive belt XM-5 driven from a stationarily mounted motor XM-4. The drive belt XM-5 is angled with respect to a vertical plane perpendicular to the shaft XM-2 the same angle as the angle at which the lamination plies or layers XL-1 through XL-7 are fed through the mandrel. The drive belt XM-5 in addition to being wrapped around the tube, also passes over an idler pulley XM-5&#39; and drive pulley XM-4&#39;  along with the latter pulley being driven by the motor XM-4 as shown in FIGS. 6A and 6B. 
     A flying cut-off saw XM-6, which advances rightwardly in a direction parallel to the axis of shaft XM-2 at the same speed as the spirally wound hexagonal wall XWC moves rightwardly, as viewed in FIG. 6A, operates to cut the spirally wound tube formed by the mandrel as it leaves the right hand end of the mandrel with the cut being made along a plane perpendicular to the symmetrical axis of the hexagonal wall module XWC. At the conclusion of the cutting operation, the flying cut-off saw XM-6 reciprocates back leftwardly, as viewed in FIG. 6A, to a home or start position shown in phantom lines. Thus, each cut is initiated with the saw XM-6 in the dotted line position and concluded with the saw in the solid line position as shown in FIG. 6A. 
     Acting in concert with the cut-off saw XM-6, a reciprocating cylindrical catcher (not shown) will support the hexagonal module wall XWC during the cut-off operation and when this is completed will clear the cut-off area deposit the wall XWC in the end capping area and return to receive the next section of hexagonal tube. 
     In other embodiments of the invention, the use of convolute wrapping techniques and the use, with spiral or convolute wrapping, of fewer or a greater number of plies can approximate the same result. 
     As viewed in FIG. 8, the hexagonal building module X can be provided with a doorway DR fitted with a hinged DR-1 which swings inwardly, as well as with a window WW-1.

As illustrated, the &#34;down&#34; run extends from landing ST-1 associated with door DR-0 and continues, via mid-level landing ST-1&#39;, counterclockwise for a full flight of 14 risers to a point one story below the point of beginning. The &#34;up&#34; run extends from landing ST-1 and continues, via an upper mid-level landing (not shown), clockwise for a full flight of 14 risers to a point one story above the point of beginning. For the usual 105&#34; floor-to-floor rise in residential and light commercial construction, the 14 equal risers would each be an optimum 71/2&#34;. If mid-level egress is desired, a door may be provided proximate the mid-level landing ST-1&#39;. A wall mounted handrail ST-6 is provided for the &#34;down&#34; and &#34;up&#34; runs. A skylight SL-1 may be provided over the hexagonal helical core ST-5 and windows may be placed in the module walls XW as desired. 
     FIG. 27 depicts the uppermost, lowest or intermediate stacked module of this invention equipped to operate as an elevator.
