Abstract
This invention is a new concept in prefabricated buildings, components and methods of making the components and methods of erecting the buildings. A typical wall of the new building consists of a plurality of alternately positioned wall panels and support columns, where each support column is situated between two adjacent facing side edges of two wall panels. Coupling elements connect the support column to the two panels, and a single activation element on the support column causes these coupling elements to pull the wall panels into correct elevation and secure engagement with the support column and also secures the support column to an anchor pin in the foundation directly below the support column. This support column consists of an outer tube and a shaft slidable within the tube. First coupling elements extending from each side edge of the support column, and mating second coupling element are situated in the side edges of each panel for cooperation with the first coupling elements. Drawing the shaft upward causes mutual engagement of the first and second coupling elements and causes secure engagement of the support column with the anchor pin.
Description
- This application claims priority under 35 U.S.C. 119, 120 based upon applicant's Provisional Application, Ser. No. 60/857,732, filed Nov. 7, 2006.
- 1. Field of the Invention
- This invention is in the field of prefabricated buildings and methods of erection of prefabricated buildings.
- 2. Background
- There is a worldwide need for buildings of all types, including homes, hospitals, school and factories, this need being particularly acute in areas of natural disasters such as occurred with the Tsunami and Hurricane Katrina and in war-torn areas. The need is also great in many under-developed areas and countries and even in developed countries where cost, speed and ease of construction have become great concerns. Thus, a first set of basic objectives is for prefabricated homes that have low cost, safe and secure construction, good insulation from heat and cold and durability. Obviously, an attractive appearance would be quite desirable since many prior art prefabricated buildings have nondescript or poor appearance. Fireproofing is a still further objective, but difficult and expensive because conventional materials are primarily wood and wood products.
- Vast amounts of wood materials are used and thus consumed in worldwide home and building construction for framing, inner and outer walls, floors and roofs. Thus, a worldwide wood consumption cycle is well along with no end in sight, as forests are being destroyed and wood from demolished and replaced homes is often burned or otherwise disposed of without useful recycling. Another problem in prefabricated building construction is the time to manufacture components, to transport and erect the components, and a requirement for skilled persons with professional equipment and power tools to achieve assembly and erection of the buildings. Finally, the economics of high volume usually precludes much variety or esthetic considerations.
- This present invention includes a new prefabricated building concept, components, sub-assemblies, fully erected buildings and a method of assembly or erection of such buildings. A principal object of this invention is to provide buildings that can be erected very quickly and easily and by persons who may not be professionals in this field and who may have little or nor power equipment, and/or who may be erecting such buildings in remote and primitive regions.
- A further object of this invention is to provide buildings, and housing type buildings in particular, that are extremely inexpensive as regards cost of components and labor.
- Another object of this invention is to provide prefabricated housing that can be erected by persons who do not need to be trained and experienced carpenters, bricklayers, plumbers, electricians, painters, etc.
- A still further object of this invention is to provide prefabricated housing which is strong, safe, well insulated from heat and cold and is fireproof.
- An additional object of this invention is to provide prefabricated houses that do not require wood as a basic construction component, which helps conserve the world's forests from destruction.
- A related object of this invention is to provide housing having such good insulation characteristics at a reasonably low cost, that there will be a greatly reduced need for heating fuel, be it from wood, wood products, coal, oil, gas, or even electrical, and wind power. Such reduced fuel needs conserve natural resources, reduce environmental pollution from combustion and reduce operational costs of living in such buildings.
- A still further object of this invention is for the components of such new buildings, particularly the modular wall, roof and floor panels, to be light weight and thus easy and inexpensive to transport and to handle during erection of the buildings.
- An additional object of this invention is to use components, particularly wall, roof and floor panels, which can be manufactured in factories that can be easily set up near the locations where the building will be erected.
- A further object of this invention is for the coupling elements that join wall panels and other components to be simple to understand and easy to use.
- An additional object is for these buildings to be adapted for assembly in rural or even remote and undeveloped areas, including deserts and jungles, where conventional roads, machinery, equipment and skilled artisans are few or non-existent.
- These and other objects of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.

FIGS. 1 to 22 illustrate my new prefabricated building invention which includes: (a) an assembled prefabricated building, (b) the subassembly of a single wall or wall section formed of key structural components of wall panels and support columns, (c) a method of assembly or erection of such a building, (d) a new wall panels alone, and (e) the method of making the new wall panel. - A
typical building 10 constructed according to this invention comprises side and endwalls 11 formed of alternately spacedwall panels 12 andsupport columns 14. Such walls are secured to afloor 22 or other foundation and support aroof 15 comprising a roof truss androof panel 18. More specifically, eachside wall 11 is formed of alternately positionedupright wall panels 12 andupright support columns 14, where eachcolumn 14 is situated between and releasably coupled to facingside edges 12A of twoadjacent wall panels 12. A typical wall panel has width of four feet and height of eight, ten or more feet in height. Obviously, acomplete wall 11 comprisingmany wall panels 12 may vary in length and height, and may include doors and windows as desired. Also, as discussed later,wall panels 12, as modular units ofwall 11, may have customized sound and heat insulation properties, customized esthetic interior and exterior surfaces and built-in HVAC, plumbing and electrical components.Roof 15 is constructed in a manner generally similar to that of the walls, withroof panels 18 releasably coupled to roof beams 20 situated between facing side edges of adjacent roof panels. Optionally, other roof structure is possible, but such would not necessarily employ and take advantage of the present invention. The building also hasfloor 22 and anchor 23 components, and may utilize floor panels, generally similar to wall panels but having properties appropriate for a floor. The support columns structurally integrate the walls, roof and floor as will be described in later sections. - As noted above and as seen in FIGS. 1 and 5-11,
walls 11 of the new prefabricated building are constructed of alternately spacedwall panels 12 andsupport columns 14. For convenience, this description and the claims will refer when appropriate to a coupling means 1 which comprisescoupling elements 2 and 3 for connectingwall panels 12 to asupport column 14, anchor connection means 4 for securing asupport column 14 to the anchor means 23, and actuation means 5 for actuating said coupling means 1. - (1) Support Column
- A
typical support column 14 as seen inFIGS. 5-11 comprises anouter tube 14A and a shaft or drawbar 25 slidable in tube 14A. Saidouter tube 14A hastop part 14T,bottom part 14B andopposite side walls 14E.Tube 14A also has front or insidewall 14C and rear oroutside wall 14D that correspond respectively to interior and exterior surfaces ofwalls 12 ofbuilding 10. - The above mentioned coupling means 1 comprises first coupling elements 2 on each side edge of each
support column 14 andsecond coupling elements 3 on eachwall panel 12. As further described, eachsupport column 14 has on eachside edge 14E five axially spacedcoupling elements 3, each comprising a set of wings orjaws column 14A are adapted to cooperate with five coupling elements 3 (designated 3A-3E) on theside edge 12A of eachwall panel 12. As illustrated, each coupling element 2 comprises a set of wings, wherewing 29 is fixed toside edge 14E ofouter tube 14 andwing 30 is carried byshaft 25 and movable to approachwing 29 whenshaft 25 is drawn upward relative toouter tube 14A. The actual number, size and form of coupling elements may vary from the preferred constructions illustrated herein. - For cooperation with these five
first coupling elements 2A-2E on eachside edge 14A of eachsupport column 14 are five second coupling elements (3A-3E), each second coupling element comprises arecess 26 and apin 43 in the side edge of a typical wall panel. - Each of
coupling elements 2A-2E onsupport column 14 engages and locks onto apin 43 of acorresponding coupling element 3A-3E of a panel when the panel is positioned for engagement and connection to the support column. - (2) Wall Panel
- As seen in
FIG. 2 particularly and inFIG. 2A , eachwall panel 12 has side edges 12A, and in eachside edge 12A is a series ofcoupling elements 3A-3E, each consisting of a pocket orrecess 26 and apin 43 fixed in the pocket. Eachrecess 26 andpin 43 fixed therein functions as acoupling element 3 of coupling means 1 for connecting a wall panel to asupport column 14. These recesses are axially spaced apart to correspond to and receive said axially spaced apartfirst coupling elements 2A-2E, each consisting of a set ofwings panel 12 isurethane foam 38. - For each set of wings the
movable wing 30 includes a hook-like groove 30A. For coupling of awall panel 12 to thesupport column 14, each set of wings extends laterally from thesupport column 14 into arecess 26 in the side edge ofwall panel 12 and engages and releasably couples withpin 43 in the panel. Thus, the panel is maneuvered into position until each of the five recesses on one side edge receives therein one set of wings, withpins 43 moving between each said two wings of each set and into said locking groove 34. - As seen in
FIGS. 7 , 7A and 7B, in a typical set of wings the fixed upper wing 29 (a) has a taperedtop edge 29A for easily entering acorresponding recess 26 in apanel side edge 14A, and (b) has a generally flat or horizontalbottom edge 29B that has with a slightupward taper 29C at theouter end 29D. As seen inFIGS. 11 fixed ortop wing 29 is displaced laterally behindmovable wing 30 and toward the exterior side ofcolumn 14. Themovable wing 30 of each set of wings is situated belowtop wing 29 and is axially movable within an axial slot 31 in theside wall 14A ofcolumn 14. - Below each fixed
wing 29 ismovable wing 30 attached to and moved bydraw bar 25. At the top edge ofwing 30 is agroove 30A creating a hook-like recess to receive and capture apin 43 ofcoupling element 3 ofwall panel 12. - As noted above, each
column 14 comprises an inner shaft or drawbar 25 slidable within saidouter tube 14A. As seen inFIG. 8 and also inFIGS. 7 , 7A and 7B, drawbar 25 has its ownaxial slots 32 to receivehook elements 33 of eachlower wing 30. When assemblingwings 30 ontodraw bar 25, eachwing 30 is moved laterally until its twohook elements 33 enter and pass through slot 31 on the side edge ofouter tube 14A ofsupport column 14, and thence eachelement 33 enters aslot 32 ofdraw bar 25 and drops down into full engagement. Later, upward movement ofdraw bar 25 will drive allhook elements 33 upward so that the edge ofgroove 30A in the top edge ofhook element 33 will approach thebottom edge 29B of fixedwing 29 andcapture pin 43 there between. - To achieve this arrangement of draw bar, wings and outer tube components,
movable wings 30 are attached afterdraw bar 25 is situated within the bore ofouter tube 14A andslot 32 is aligned with slot 31 ofouter tube 14. As seen, drawbar 25 has five axially spaced (movable)wings 30 on each side, which operate with five fixedwings 29 on each side of outer tube 24, thus producing five sets of wings on each side ofcolumn 14. Each set of wings is one of thecoupling elements 2A-2E. Axial movement upward ofdraw bar 25 withinouter tube 14A will move each top andbottom end beam 39 andwing 30 upward toward corresponding fixedwing 29 ofouter tube 14A. - Before describing how a
panel 12 is coupled tocolumn 14, first note the panel structure as seen inFIGS. 2 , 3, 4 and 5.Panel 12 consists primarily ofinner frame 40 havingside beams 41 withpockets 42 spaced along the length of eachside beam 41. Eachpocket 42 is formed by a generally triangular cup withpin 43 extending transversely across and fixed in each cup. In a manufacturing process to be described later, sheets orskins wall panel 12. - Now, note that
FIG. 5 shows twopanels 12 being moved, as indicated byarrows 45, toward both opposite sides of asupport column 14. Couplingelements 3A-3E, each comprising apocket 26 andpin 43 are generally aligned withcoupling elements 2A-2E, each comprising a set of upper andlower wings FIG. 6 illustrates a section ofwall 11 where twowall panels 12 have converged laterally against acolumn 14.FIG. 8 indicates schematically how two wall panels (not shown) ofFIG. 5 approach opposite side edges of acolumn 14 and become coupled thereto. InFIG. 8 the wall panels are not shown, but representing each wall panel is acircle 43 A representing pin 43 as the wall panel is moved towardcolumn 14. If a wall panel's elevation is not properly aligned withspace 46 between upper andlower wings edge 29C ofupper wing 29 will guidepin 43A intospace 46 and then downward intogroove 30A. -
FIGS. 8 , 9, and 10 illustrate schematically twowall panels 12 moving and moved into engagement with bothsides 14A of asingle support column 14. The two wall panels are not shown; however, pins 43A or 43B represents one of thecoupling elements 2A-3G in a typical wall panel. Oncewall panel 12 and its pin 43 (this pin representing the fivecoupling elements 3A-3E) moves sufficiently inward towardcolumn 14,pin 43 will reach the position indicated by 43B. At this time, upward movement ofdraw bar 25 has drivenlower wing 30 upward, and taperededge 30B ofwing 30 has driven or cam pin 43 (43B) further inward towardcolumn 14. Full upward movement ofdraw bar 25drives pin 43 upward againstbottom edge 29B of fixedupper wing 29, which thus positionspanel 1 2 at the correct elevation relative tocolumn 14. This guidance and capture ofpin 43 bywings wall panels 12 to supportcolumns 14, creating walls of desired length. Because the proper alignment of eachpanel 12 is predetermined, the coupling means 1 cannot overdraw ordamage pin 43 or the panel in which it is fixed. - Activation of
draw bar 25 withinouter tube 14A of eachcolumn 25 achieves a plurality of functions: (a) engaging and pulling the panels to be closely adjacent the column, (b) moving the panels to the correct elevation and orientation relative to the column and (c) securing the panels to the column. Said activation also releasably secures the column and attached panels to the anchor, floor orother foundation 22. - As seen in
FIGS. 5 , 6 and 1, eachcolumn 14 has abottom end 14B that becomes secured to thefloor 22, anchor or other foundation component and atop end 14T that becomes coupled to and supportsroof 15. Eachcolumn 14 serves a plurality of different functions with simplicity, efficiency and security, as described below. -
FIGS. 9 , 10, 10A and 12 illustrate afirst embodiment 4A of theanchor coupling 4, andFIG. 18 illustrates asecond embodiment 4B of such coupling. As seen in these figures coupling 4A consists ofrod 51 havinghook 52 at the bottom that engageshorizontal anchor pin 53 that is securely embedded or otherwise fixed in thefloor 22 or in a jack stand 100 (FIG. 9 ) secured in the ground. In the course of erecting abuilding 10,draw bar 25 is coupled viarod 51 andhook 53 to anchorpin 53, which will anchor to the ground the connected components (drawbar 25,support column 14 and attached wall panels 12), as further explained below. - As seen in
FIGS. 9 , 10 and 12,draw bar 25 has at its lower end, belowwings 30,variable length coupling 4A which consists ofrod 51 whose lower end is pivotably coupled to anchorpin 53 and whose threaded top end is fixed via locking nuts 57 toblade 56. InFIG. 18 there is a variation in the form of an upward extendingrod 55 whose top end is similarly fixed toblade 56, but whose bottom end is fixed in the floor orfoundation 22 with no pivoting capability. In both of theseembodiments blade 56 is secured torod blade 56 can be adjusted so thatslot 58 inblade 56 will have its top and bottom ends located at predetermined elevations relative to anchorpin 53 or to thetop reference surface 100A of the anchor pad or jack stand, whichever is established as the basic reference elevation. - As seen in
FIG. 12 , at the top end ofslot 58 ispin 59 fixed to the lower end ofdraw bar 25. Further, as seen, drawbar 25 is in its uppermost or second position, sincepin 59 is barred from further upward movement by the top end ofslot 58. In this upperposition draw bar 25 has pulledadjacent wall panels 1 2 closely and securely against thesupport column 14. - More specifically, when
upright support column 14 is positioned directly aboverod 51, and draw bar 25 (slidable within column 14) has its lower end coupled torod 51,draw bar 25 is then slidable withinsupport column 14 within the limit of length L ofslot 58. - This movement of
draw bar 25 is coordinated withmovable wings 30 secured thereto, so that upward movement ofdraw bar 25 to its limit perslot 58, will bring eachwing 30 to the predetermined correct elevation belowwing 29 to pullwall panels 12 inwardly to the correct tightness againstcolumn 14 and to the correct elevation relative to foundation orfloor 22. - As described briefly earlier, actuation means 5 actuates coupling means 1 which pulls
draw bar 25 upward and drawspanels 12 inward againstsupport column 14. The actuation means 5 includes (a)main nut 74 on threadedrod 66 extending from the top ofdraw bar 25, and (b)block 68 fixed to a top portion of 14T ofsupport column 14. As seen inFIGS. 13 , 14 and 14A, drawbar 25 is drawn upward relative toouter tube 14A by rotatingmain nut 74. As will be further described, the engagement of the bottom ofdraw bar 25 viacoupling 4A to the anchor means 23, simultaneously securesouter tube 14A ofcolumn 14 to thefloor 22 and secures twowall panels 12 at the correct elevation and tightness tocolumn 14, while barring over tightening forces that might be applied topins 43 in the wall panels. - Coupling 4A has a height adjustment available via the set of locking nuts 57, whereby variations in the elevation of the floor or
foundation 22 and length ofrod bars 25 in thevarious support columns 14 and allwall panels 12 will be at the same elevation. - As seen in
FIG. 13 , the top end oftube 14A ofcolumn 14 includes fixedblock 68. The top end ofdraw bar 25 includes fixedblock 65. Threadedrod 66 coupled to block 65 extends through bore 67 inblock 68, and rotation ofmain nut 74 onrod 66 pullsdraw bar 25 upward relative toouter tube 14A. As seen inFIGS. 13 and 14 ,outer tube 14A ofcolumn 14 in this embodiment is a rectangular tube havingside walls 14E, front orinner wall 14C and rear orouter wall 14D.Block 68 fixed toouter tube 14A ofsupport column 14 is supported by resting on cut-out edges, 14X, 14Y of front andrear walls side walls 14E. Consequently, any downward pressure on edges 14X, 14Y, urges thesupport column 14 downward against thefoundation 22. - Tightening of
main nut 74 in a single step “locks down”column 14 against the floor orfoundation 22 and simultaneously pulls upward ondraw bar 25 and drawsinward panels 12. More specifically, lock downnut 74 when rotated by a wrench, bears downward onblock 68 which bears downward on edges 14X, 14Y of outer tube 24 ofcolumn 14 which has itsbottom end 14B driven downward against thefoundation 22. - The reason downward force on
column 14 is achieved is that rotation ofnut 74 causes pulling upward onrod 66. As described earlier,rod 66 is fixed to the top end ofdraw rod 25 whose bottom end is coupled to the fixed floor or anchor. Also, as described earlier, pulling upward initially causesdraw bar 25 to move upward, aswall panels 12 are drawn inward to and againstcolumn 14. Continued upward pulling on draw bar 25: (a) cannot further lift the draw bar because such is barred and limited byslot 58 in anchor connection 5, and (b) can only apply further downward force onouter tube 14A ofcolumn 14 against the foundation.Lock nut 74 is then torqued to the proper final force for this assembly. - As seen in
FIGS. 10 , 10A, 12, and as described in Sections C and D above, the lower part ofdraw bar 25 engages a foundation orfloor 22 or anchor 23 in the ground byanchor connection 4 comprisingrod 51 extending downward to anchorpin 53. As seen,rod 51 has abottom hook end 52 that engages fixedpin 53 and a threaded top end. Also shown isanchor plate 54 whose neck is situated inside the bottom end ofouter tube 14A to stabilize it from horizontal slippage. As seen inFIG. 10A , tightening lock-downnut 74 atopblock 65 fixed toouter tube 14A ofcolumn 14, pullsdraw bar 25 upward, thus, affecting an upward force F1 inrod 66, seen as force F1′indraw bar 25, and seen as force F1″ inanchor rod 51 and thus also onanchor pin 53. This upward force generates a reaction downward force F2, F2′ in the walls ofouter tube 14A ofcolumn 14, which downward forces becomes applied to the foundation orfloor 22. Also, as previously described, the upward force F1 applies force vectors F3 and F4 to pin 43 for drawing the wall panels inward and upward. - A number of different foundations or floors may be employed depending on the land conditions, equipment and materials available or still other factors. For example, there may be a poured concrete floor covering the entire area of the building to be erected, or there may be only individual pilings or jack stand foundations situated at the site of each upright support column, or some combination of the above. In all cases it is necessary to establish a very strong fixed anchor element at each location below an upright support column.

FIGS. 7 , 7A, 9, 10 and 12 illustrate ahorizontal anchor pin 53 embedded in jack stand 100 (FIGS. 7 , 7A, and 9) or embedded in floor 22 (FIGS. 10 and 12 ). Engaged to anchorpin 53 in each figure ishook 52 at the bottom end ofrod 51. Because of the relationship of the generally round cross-section ofhook 52 and round cross-section of the hook,rod 51 can easily angulate in all directions from straight to accommodate any failure of acolumn 14 to be situated directly over the center ofpin 53 androd 51. - The later connection of the top end of
rod 51 to the bottom end ofdraw bar 25 has been described above.FIG. 12 shows how theslot 58 inblade 56 andpin 59 inslot 58 arrangement allows further angulation ofrod 51, if necessary.FIG. 18 illustrates arod 55 fixed in a foundation, but includingblade 56,slot 58 andpin 59. A typical jack stand, as seen inFIG. 7A , has a truncated pyramid shape with a seven inch square plate at the top, and eighteen inch square plate at the bottom, and a twenty-four inch height. -
FIGS. 1 , 7B, 13, 14, 14A and 14B illustrate the haunch coupling of the roof truss to supportcolumns 14. In this roof truss system horizontal roof beams 80 span the space betweenside walls 11, with eachend portion 80A of abeam 80 removably coupled to the top portion of oneupright support column 14. As seen inFIGS. 14 and 14A ,end portion 80A ofbeam 80 rests uponblock 68 which rests on cut-out ledges 14X, 14Y of the front andrear walls outer tube 14A ofcolumn 14.Rod 66 extends upward fromblock 65 in draw bar'sclearance hole 68A inblock 68. Lock downnut 74, when rotated, pullsdraw bar 25 upward to its maximum height set byslot 58 situated at the bottom ofouter tube 14A (seeFIG. 12 ). In this upward position, withnut 74 tightened down,adjacent wall panels 12 will be drawn in to their connect position of elevation and closeness tocolumn 14. This fixes and stabilizes the wall panels to the column and locks down that column and panels to the floor or anchor. -
Horizontal beams 80 join and support theopposite side walls 11. Eachinclined roof beam 81 is situated between the facing side edges of twoadjacent roof panels 18, which are drawn securely towardbeam 81 by an internal draw bar similar to drawbars 25 employed in the side wall construction.Roof panels 18 are sufficiently light weight that they can be easily lifted, positioned and secured to roof beams 81. As evident inFIG. 13 , the single lock downnut 74 secures the wall panels into a wall construction, and the single lock downnut 82 secures roof beams 80, 81 to the wall structure. - Roof beams 81 are partially similar to support
columns 14, in that each includes a slidable draw bar and sets of fixed and movable wings for engaging pins in pockets ofroof panels 12, which are generally similar towall panels 12. A series of alternatively spacedroof panels 18 and roof beams 20 create a roof section 70. As seen inFIG. 16 , which is a sectional view taken fromFIG. 1 , each twoadjacent roof panels 18 joined by aroof beam 20 have additionalsealing strip elements internal gasket 74. When twoadjacent roof panels 18 are drawn and secured to aroof beam 20, as seen inFIG. 16 ,seal strip 71 automatically slides over and resiliently locks by thehook part 73 ontoseal strip 72.FIG. 17 shows anadditional seal 75 for adjacent top edges of two roof sections. - The alternative roof truss system of
FIG. 1 includes lower horizontal roof beams 90, inclined roof beams 91, longitudinal rooftruss header beam 92, and side wall header beams 93 which interconnect the top parts ofsupport columns 14 of the side walls. With this roof truss system that is independent of the roof panels, the roof section is assembled ofpanels 18 and support beams 20, one-after-another, into a roof section that lies upon and is supported by the basic roof truss system. - This arrangement demonstrates another aspect of the present invention which reduces labor, parts, and cost and thus speeds erection of the building, while assuring a reliable seal.
- As seen in
FIGS. 1 and 15 , the corner construction ofside walls 11 and end walls employs a cornerupright support column 101 and drawbar 102 generally similar to acolumn 14 and drawbar 25, except that thewings wall panels 11 respectively. Pulling up ondraw bar 102 will causewings pins 43 of the respective panels and to draw these panels inward againstcolumn 101. - The
floor 22 as seen inFIG. 1 is poured concrete or other material with anchor or hold-downrods FIGS. 12 and 18 respectively, embedded or secured in the floor. The floor may be as primitive as bare dirt, so long as the anchor elements 23 are strong enough and sufficiently embedded to securely hold down and stabilize the walls attached to said anchor elements. - The floor may alternatively be constructed of floor panels in a manner generally similar to construction of a
wall 11, with floor beams and draw bars between facing side edges of adjacent floor panels. - Strength, heat and sound insulation properties would be designed into floor, wall and roof panels as desired. These panels may also include modular segments of HVAC, electrical telecommunication wiring, plumbing, etc. so that assembly of the panels into floor, wall and roof sections automatically creates the basic network of HVAC, electrical, telecommunicating and plumbing systems.
- For this description of the building erection procedure, it shall be assumed that a variety of preliminary steps have been completed, namely:
- (a) that the components are constructed and are readily available at the erection site, these components including all the
wall panels 12,roof panels 18, support column and drawbar units 14/25, and roof beams and correspondingdraw bar units 20, and - (b) that all the anchor pins 53 and upward extending
anchor rods 51 are positioned and secured either in a poured concrete floor or in pilings, jack stands or in other foundation means, all at the reasonably accurate elevation and distances from each other. - The next steps in the preferred method of erection of the building are as follows; however, numerous variations are possible:
- 1. Position a corner
wall support column 101 as seen inFIGS. 15 and 1 ) this support column has two panel-engaging sides 90° apart, above the anchor pin in the corner location; - 2. Bring the side edge of a side wall panel into close proximity with each of said panel-engaging sides of said corner column, until each set of first coupling elements (2A-3E), namely each set of upper and
lower wings corresponding recess 42 of one of thesecond coupling elements 3A-3E in a side edge of the panel, until thecoupling pin 43 in each recess is correctly in thespace 46 between said wings. If necessary the tapered edges ofwings 29 will guide orcam pin 43 to the correct elevation, thus correctly positioning the panel as regards its orientation and elevation, seeFIG. 8 . Bothpanels 12 oriented 90° apart are now in initial engagement withcorner support column 101. It is assumed at this time that thelower end 14B ofdraw bar 102 is properly connected to the anchor pin directly belowsupport column 101. - 3. Pull upward draw bar 102 (
FIG. 15 ) until each pins 43 is securely positioned between each set ofwings column 101, the column being securely connected to anchorpin 43 below the column. - 4. Two wall panels 11 (FIG. 15,1) at 90° to each other are now upstanding and coupled to the
corner column 101, and each of these wall panels has an exposed opposite side edge remote from the side edge coupled to the corner column. Adjacent each of said exposed side edges of the panels is positioned anew support column 14. Thedraw bar 25 of each new support column is coupled to an anchor pin below it, which may require tilting of the column and may require momentarily sliding the bottom end ofdraw bar 25 out of the bottom end of theouter tube 14A. For convenience, the above-mentioned first wall panel forming the corner will be designatedPanel 1. The new support column adjacent to the exposed edge ofPanel 1 will be designatedColumn 1. - 5. In addition to connecting
Column 1 to its anchor pin,Column 1 is adjusted in position and orientation so that its coupling elements (2A-3E), namelywings Panel 1; however, coupling ofColumn 1 andPanel 1 is not yet complete. - 6. A new wall Panel 2 is now positioned adjacent the other side of
Column 1, until the coupling elements (2A-2E) namely, the sets of wings ofColumn 1, enter corresponding coupling elements (3A-3E) namely recesses 42 in the adjacent side edge of Panel 2. - 7. Next, draw
bar 25 withinColumn 1 is pulled upward which drawsColumn 1 towardPanel 1 and draws Panel 2 towardColumn 1, until Panel 2 is upright and properly aligned, consistent withPanel 1. - 8. As seen in
FIGS. 19 , 20, and 21, this procedure is repeated for the length of the side wall, followed by attachment of another corner column, followed by attachment of “end” wall panels. - 9. With the
walls 10 essentially complete, horizontal roof beams 80 are positioned with theirends 80A coupled into the top ends ofopposite columns 14 inopposite side wall 10. Theupstanding rod 66 of eachcolumn 14 extends through holes in said ends of roof beams 80. - 10. Next, an
inclined roof beam 81, which includes a draw bar assembly for engaging roof panels, is positioned with its lower end positioned adjacent theend 80A ofbeam 80 top wall column.Rod 66 extends through both beams, and lock-downnut 82 is installed to secure both beams tocolumn 14. The upper ends of roof beams are supported by aheader beam 92 extending lengthwise of the building,FIG. 1 . - 11. Next, a
first roof panel 18 is positioned with one side edge and its recesses closely adjacent a first roof beams, until the sets of wings enter the pockets in the side edge of the first roof panel. The draw bar inbeam 81 is pulled axially until roof panels on both sides are drawn-in and properly and snugly positioned. - 12. Additional roof beam/draw bar component and roof panels are consecutively placed in a manner generally similar to the erection of a side wall and is continued to complete one side of a gabled roof.
- 13. A variety of subsequent finishing steps will be executed as selected, including connection of electrical, water and HVAC components through panels and columns. Various details associated with individual components and discussed above, such as connecting the bottom of each draw bar to the corresponding anchor pin, have not been described again. Also, not described here are methods of accurately positioning and establishing the correct elevation of jack stands and anchor pins.
- Wall panels as seen in
FIGS. 2-6 , having the dimensions and physical properties required for a prefabricated building as described herein, may be made by numerous manufacturing processes; however, the preferred process which is consistent with concepts of the present invention: - (a) uses non-wood materials such as plastics, fiberglass and composites which reduce consumption of forests, and which have good heat and cold insulation properties and thus further reduce the consumption of wood and other natural resources and energy for heating and cooling,
- (b) uses methods and manufacturing equipment that can be easily transported, set up and used to produce wall panels and support columns at very high speed and low cost,
- (c) produces panels that are strong yet extremely light weight so that transport, storage, and assembly will not require heavy equipment, and
- (d) produces panels which can have a great variety of textured, colored, aesthetic and functional external and internal surfaces.
- The new panels seen in
FIGS. 2 and 4 are manufactured by a method using a mold shown schematically inFIG. 22 which includes the following steps: - Step 1: The
skins Class 1 fire rating. - Step 2: The
internal frame 40 of each panel comprises two identical side legs 44, each having equally spacedpockets 42 and top andbottom end legs 39 whose ends are joined to the side legs to form a picture frame; however, the top leg includes a rake angle from front to rear to accommodate the slope of the roof. Thus, the inside of the picture frame and theinside skin 44A will be slightly taller than theoutside skin 44B, as seen inFIG. 4A . Instead of joining side and end legs, the legs of this picture frame can be formed in a single step mold. This frame may be made of a fiber glass and resin combination or of any other materials having suitable strength characteristics for the temperature and environmental conditions of molding and of use in buildings. - Step 3: A mold, as seen in
FIG. 22 , holds the fabric sheets and frame of a single panel.Urethane foam 38 is injected into the space within the frame and between the skins, the skins are bonded to the frame, and a unitary one-piece panel is created. Thereafter, holes are drilled or machined to receivepins 43 for coupling to the previously described support column/draw bar subassemblies 14. Optimally, pins 43 may be placed within the mold before injection. - Step 4: The top and
bottom legs 39 of each frame includeholes 86 along their length to receive injection nozzles (not shown) for entry of the urethane foam that expands 1200% in 40 seconds. Hole size depends on the volume of the cavity and the speed of the urethane. After injection, the nozzles are retracted and the holes are sealed. Heat from and during injection is about 100° F. which is maintained for about 45 seconds. - Step 5: For each panel, injection cycle time is one minute and cure time is 10 minutes. The fiberglass skin may be manually placed in the mold, or with a PFE (Precision Feed End Effector) the skin can be laid up in the mold with optional wet, dry or prepreg gel coat, or the gel coat may be sprayed inside the mold before the skin is situated therein. Preferably a robot will apply the gel coat since it is highly combustible and the robot is sufficiently explosion-proof. Also, the robot can maneuver into confined compartments or unfriendly environments and can move molds with gel coat to safer location.
- Step 6: The fiber glass and
epoxy mold 83 in a preferred embodiment opens like front and rear book covers 83A open from the core pages of a book. -
End plates 84 of the mold overlie the top andbottom beams 39 of thepicture frame 40.Holes 85 inend plates 84 are aligned withholes 86 in said top andbottom beams 39 offrame 40, so that injected foam can pass through the mold end plates and the frame end wall, into thepanel cavity 87. Theskins frame 40. - Step 7: High Speed Manufacturing Sequences:
- With selected number and sequencing of molds, panels can be made at the rate of one per minute or theoretically 43, 200 per month with this arrangement:
- (a) skins are made at the rate of one per minute,
- (b) frames are made at the rate of one per minute,
- (c) two skins and one frame converge to form a panel cartridge (with injection and 1200% expansion in 4 seconds) and movement of mold to a cooling line for ten minutes, and
- (d) with ten cooling lines, each taking ten minutes, a staggered arrangement will produce one panel every minute. This is illustrated in attached Appendix A.
- This is all robot controlled and thus requires essentially no human labor except for basic supervision and maintenance. This panel construction is applicable for wall, roof and/or floor panels. Panel shape may be flat, curved or otherwise. Surface texture, color, graphics or other esthetic on interior and exterior panel surface is possible.
