   BRIEF SUMMARY OF THE INVENTION 
   The present invention provides a metal building that includes an underlying support such as a slab supporting a plurality of walls that are formed of generally vertically oriented interlocking metal panels, each wall having an outer surface and an inner surface. 
   The metal panels include wall panels having opposed wall panel edge portions. The metal panels also include a plurality of metal corner panels having opposing corner edge portions that each connect with a pair of wall panels at wall panel edge portions. The wall panel edge portion of one panel connect with edge portions of two other metal panels such as for, for example, a corner panel and a wall panel, or two wall panels, or a panel that is part of a door or part of a window truss. 
   Each of the panels have side panel sections with respective opposed flange portions that extend toward each other. Connections join the panels together at interlocking sections that are in part Z-shaped and that extend transversely with respect to the wall outer surface. 
   The wall inner surface is preferably defined by a veneer (for example, sheet rock, wood paneling, synthetic paneling or the like) that is connected to the metal panels at the flange portions. A cover (for example, roof) attaches to the walls to shield all or part of the interior of the building from the elements. 
   The metal building preferably includes at least one wall with a door. The metal building can include at least one wall with a window. The wall panels each have a width. The door has a width. The door width is less than the width of a plurality of short wall panels that are part of a truss positioned above the door. The wall panels have a width and each window has a width. The window width is less than the width of a plurality of the wall panels that are part of a truss positioned above and/or below the window. 
   A truss can be provided that is formed in part of a plurality of short wall panel sections that are attached above and below to truss beams, the truss having edge portions that connect to full length wall panel edge portions. 
   Vertical columns can be provided that support the truss at positions on opposing sides of a window, wherein the distance between the columns is greater than the width of the window. Each of the columns preferably supports an end portion of the truss that is supported above the window. A somewhat similar arrangement utilizes a truss above each door. Each column can include a pair of sections that are movable relative to one another. 
   Corner constructions are provided that enable standard width interlocking wall panels to be utilized. In one embodiment, the corner construction uses a corner panel having two panels or legs that form an angle of about ninety degrees and that can be of the same length or different lengths. 
   In another embodiment, a corner column of special configuration connects with a pair of corner panels that can be of the same length or different length.

   DETAILED DESCRIPTION OF THE INVENTION 
   The present invention provides a metal building  10  that can be constructed of a plurality of connected walls  11 ,  12 ,  13 ,  14  and a cover or roof  17 . Each wall  11 ,  12 ,  13 ,  14  can be a solid wall or can be fenestrated, providing one or more windows  16  and/or one or more doors  15 . Building  10  can be constructed upon slab  63 . 
   Each wall  11 ,  12 ,  13 ,  14  is constructed of a plurality of interlocking panels. A wall that is not fenestrated is constructed using a plurality of full length panels  18  that can each be of a selected standard height, e.g. eight, ten, twelve or more feet tall. In  FIGS. 2-5 , each panel  18  is preferably vertically extended and connected to an adjacent panel (or panels)  18  or to a corner panel  37 ,  102 ,  103  (see  FIGS. 7 ,  23 - 25 ,  27 - 28 ). 
   In  FIG. 5 , the panel  18  can be seen in a plan sectional view to show its transverse cross section. Panel  18  has an enlarge planar front panel  19  connected to a pair of opposed side panels  20 ,  21 . Each panel  20 ,  21  is an interlocking panel that enables one panel  18  to interlock with another panel or  18  or with a correspondingly shaped portion of a corner panel or a truss. 
   The interlocking portions include Z-shaped sections  22 ,  23  that define an interface between the side panels  20 ,  21  and enlarged planar front panel  19 . Enlarged planar front panel  19  can be flat, defining a plane that is also the plane of the wall  11 ,  12 ,  13  or  14  that it is a part of side panels  20 ,  21  preferably form an angle of about ninety degrees with enlarged planar from panel  19 . 
   Each wall panel  18  has a pair of opposed rear panels  24 ,  25 . Rear panels  24 ,  25  extend inwardly toward each other as shown in  FIG. 5 . Z-shaped portions  22 ,  23  include diagonally extending sections  26 ,  28  respectively. The Z-shaped portions  22 ,  23  include side panel sections that form an acute angle with a diagonally extended section  26  or  28 . In  FIG. 5 , diagonal section  26  forms an acute angle with side panel section  27 . Side panel section  27  can form an angle of about ninety degrees with front panel section  19 . Diagonal section  26  forms a acute angle with side panel section  30 . Side panel section  30  forms an angle of about ninety degrees with rear panel section  24 . 
   Similarly, Z-shaped portion  23  includes diagonal section  28  that forms an acute angle with each of the side panel sections  29 ,  31 . Side panel section  29  forms an angle of about ninety degrees with front panel section  19 . Side panel section  31  forms an angle of about ninety degrees with rear panel section  25 . Each rear panel section  24 ,  25  can be strengthened by a transverse panel  232 ,  233  that extends from each rear panel  24 , toward front panel  19  as seen in  FIG. 5 . 
   Each panel  18  can be slotted to retard heat transfer between front panel  18  and rear panels  24 ,  25 . In  FIGS. 3 and 4 , two rows of slits or slots  32  are shown extending vertically along side panel section  20 . Similarly positioned slits  32  can be provided on side panel section  21 . The slits  32  have gaps  33  therebetween. Each row of slits  32  is separated from the other side by space  34  (see  FIG. 4 ). The slits  32  are staggered as shown so that a gap  33  of one row of slits  32  aligns with the center part of a slit  32  in a different row as seen in  FIG. 4 . Any other pattern of slits or holes or openings can be provided in the side panel sections  20 ,  21  that retards heat transfer between the front panel section  19  and rear panel sections  24 ,  25 . 
   In  FIGS. 1 ,  2 ,  6 ,  7 ,  8 ,  9 ,  16 , a wall  11 - 14  can be constructed of wall panels  18 , corner panels  37 ,  102 ,  103  and longitudinal beams  35 ,  36 . The beams  35 ,  36  can be channel beams as shown. A lower longitudinal beam  36  supports and is connected to wall panels  18 . An upper longitudinal beam  35  connects to the upper end of a plurality of wall panels  18 . 
   Fasteners such as sheet metal screws  38  can be used to fasten panels  18  to beams  35 ,  36 . Fasteners such as sheet metal screws  38  can be used to fasten wall panels  18  together (see  FIG. 2 ). Fasteners such as sheet metal screws  38  can be used to attach beam  35 ,  36  and panels  18  to corner panel section  37  (see  FIG. 7 ). At a corner of the building  10 , one beam  35  can be cut to provide cut-out or opening  39  that receives another beam  35 . 
   A corner is constructed as shown in  FIGS. 7 and 8 . Each corner is designated generally by the numeral  42  and is constructed using corner panel  37  and its reinforcement  46 . Panel  37  includes two panel sections  40 ,  41  that are joined together at bend  43  forming an angle of about ninety degrees. Each corner panel  37  has interlocking panels  44 ,  45 . Panel section  40  has interlocking panel  44 . Panel  41  has interlocking panel  45 . 
   Interlocking panels  44 , 45  are constructed in the same fashion as the side panels  20 ,  21  of  FIG. 5 . In fact, the corner panel  37  can be constructed by bending a wall panel  18 . In this fashion, as the wall panels  18  will interlock, one panel with the next as shown in  FIGS. 2 and 16 , a corner panel  37  will interlock with two side panels  18 . Corner reinforcement  46  has flanges  47 , 48  that attach respectively to panels  40 ,  41  as shown in  FIG. 8 . The corner reinforcement  46  provides a number of different panel sections that are connected at bends  50  or  52  as shown in  FIG. 7 . Panel section  49  connected to panel section  51  at bend  50  and panel section  51  connects with panel section  53  at bend  52 . Panel sections  51 ,  53  form an angle of about ninety degrees. A recess received Sheetrock®, synthetic wood, wood, or any other inside wall panel material known in the art. 
   Corner reinforcement  46  includes panel section  55  that connects to panel section  53  at bend  54 . Bend  56  forms a connection between flange  48  and panel section  55 . Fasteners such as sheet metal screws  38  can be used to attach reinforcement  46  to corner panel  37 . Fasteners such as sheet metal screws  38  can be used to attach wall panels  18  to corner panel  37  and wherein interlocking portions  44 ,  45  form interlocking connections as shown in  FIG. 8  with the side panels  21 ,  20  respectively of wall panels  18 . 
     FIGS. 9-16  show a construction of a wall  12 ,  13 ,  14  that provides a window  16 . In  FIG. 9 , wall  13  is comprised of an upper longitudinal beam  35 , lower longitudinal beam  36 , a plurality of full length metal wall panels  18 , a truss  60 , and a plurality of short wall panels  59 . The window  16  provides a window opening width  61  and a window opening height  62 . In  FIG. 9 , the window width  61  is less than the distance defined by a plurality of panel sections  18  or  59 . For example, in  FIG. 9 , there are five short wall panels  59  above and five short wall panels below window opening  16 . The combined width  67  of these five panels  59  is more than the width  61  of the window opening  16 . This construction enables a column  68  to be placed under each end portion of truss  60  and at the same time interlock with a full length wall panel  18 . In  FIGS. 10 and 11 , each wall panel  59  includes an interlocking end portion that is of the same configuration as the interlocking portions of the side panels  20 ,  21  of a full length wall panel  18  as shown in  FIG. 5 . These interlocking portions  69 ,  70  at the end of each truss  60  for interlocking a column  68  that supports an end portion of truss  60 . 
   The truss also includes inside plate reinforcement member  64  that includes panels  65  and  66  that form an angle of about ninety degrees. To complete the truss  60 , upper and lower longitudinal beams  35 ,  36  respectively are attached to the top and bottom of the connected short wall panel sections. 
     FIGS. 12-16  show more particularly the construction of a column  68  and its interlocking connection with an end portion of truss  60 . Each column  68  is of preferably two parts. These include column part  71  and column part  72 . The column part  71  can include three intersecting flanges  73 ,  74 ,  75  and a recess  76  that receives column part  72 . The column part  72  includes an interlocking portion  77  that forms an interlocking connection with an interlocking portion  69 ,  70  of truss  60 . 
   The interlocking connection between part  77  of column part  72  and an interlocking portion  69  or  70  of truss  60  can be seen in  FIG. 15  and is the same interlocking connection that employs Z-shaped portions used to connect wall panels  18  together and used to connect a wall panel  18  to a corner panel  37 . 
   In addition to the interlocking portion  77 , column part  71  includes flanges  78 ,  79 ,  80 . As indicated by arrows  81 ,  82  in  FIGS. 12 and 15  the column parts  71 ,  72  are adjustable with respect to each other so that the distance between flange  74  and flange  79  can be selected and then affixed using a fastener  38  such as a sheet metal screw. 
   In this fashion, any window of desired width  61  can be made by selecting a column  68  that has a combined installed width  83  ( FIG. 9 ) equal to one-half the distance that remains when subtracting the overall width of the truss  67  (always a multiplier of a panel  18  or  59  width) minus the width  61  of the window. Because each column  68  interlocks with a full length panel  18  and because each truss  60   20  interlocks with a full length panel  18 , a very strong rigidified construction can be obtained for any wall  13  that includes a window opening  16 . 
   In  FIG. 17 ,  18 ,  19  a lower longitudinal beam  84  is shown that is comprised of a web  85  and a pair of flanges  86 ,  87  each preferably forming an angle of about ninety degrees with the web  85 . Both web  85  and flange  87  are slotted. Preferably, the slot is L-shaped, so that at about the same position along the beam  84 , the flange  87  is completely slotted and the web  85  is partially slotted. This construction can be seen in  FIG. 18  wherein the slot  88  is comprised of a slotted portion  89  on flange  87  and a slotted portion  90  on web  85 . 
   Lower longitudinal beam  84  slotted portion  90  enables the front panel section  19  of a full length wall panel  18  to be placed outside of flange  87 , contacting the outer surface of flange  87 . Such a construction is useful when the building  10  to be construction is subjected to a rainy environment. The interlocking side portions  20 ,  21  of wall panels  18  pass through the slotted portion  89  and flange  87  as shown in  FIGS. 17 and 19 . The slotted portion  90  provides a drain so that any water that does accumulate on web  85  of beam  84  will drain through slotted portion  90 . 
     FIGS. 20 and 21  show a wall construction for wall  12  that has door opening  15 . As with a window, a truss  60  is placed over the door opening  15 , the width of the truss being greater than the width of the door opening  15 . The truss is supported with a pair of opposed door frame panels  92 , each having an interlocking section  93  that forms an interlocking connection with a side panel  20  of a full length wall panel  18 . This interlocking connection can be seen in  FIG. 21 . Opposite interlocking section  93  is a non-interlocking side panel  94  that can be reinforced with a vertically extended column  96  that can be in the shape of a channel beam. The door frame panel  92  can provide rear panels  95  to which Sheetrock® or other inside wall panel material  58  can be attached. 
   In  FIGS. 22-25 , a corner  97  forms the connection between two walls  11 ,  14 . Corner  97  employs a corner column  98  constructed of two column parts  99 ,  100 . These column parts  99 ,  100  can provide openings  101  so that electrical wiring or plumbing can be routed through the parts  99 ,  100 . It should be understood that similar openings  101  can be provided in the side panels  20 ,  21  of any full length wall panel  18  or in any other side panel or interlocking section disclosed herein. This enables electrical lines and plumbing to be routed within a wall  11 ,  12 ,  13 ,  14  in between section  19  and inside wall panel  58 . 
   A pair of corner wall panels  102 ,  103  are connectable to column  96  using screws  38  or other suitable fasteners. Column parts  99 ,  100  are also connectable together using fasteners such as screws  38 . Arrows  104  in  FIG. 24  illustrate the connection of corner wall panels  102 ,  103  to column  98 . Each corner wall panel  102 ,  103  provides an interlocking section  105  or  106  that can form an interlocking connection with a full length wall panel  18  such as the interlocking connection shown in  FIG. 2 . 
   Each interlocking section  105  or  106  is provided with an inner panel section  107  and  108  to which an inside wall panel can be attached. Corner column  98  can also be used with a corner panel  37  shown in  FIGS. 7 and 8 .  FIGS. 25-27  shows the use of a corner panel in combination with column  98 . It should be understood that the dimension A at  110  in  FIG. 23  for the distance between the corner column  98  to interlocking section  106  of panel  103  can be the same for both panels  102 ,  103  or can be different such as dimensions  111 ,  112  for the panel  37  shown in  FIGS. 25-27 . In  FIGS. 25-27 , the dimension  11  (Dim. B) is longer than the dimension  112  (Dim. C). This construction enables a corner panel  37  or the two corner panels of  FIGS. 22-25  to be used to adjust the two length of a wall if the full length panels  18  are of the same width and the wall dimension is not equal to an exact multiplier of that panel width. Column  98  is inserted in the direction of arrow  109  in  FIG. 27 . 
   In  FIGS. 29-32 , an insulated arrangement is shown for a full length panel  18 . The insulation includes insulation layer  114 , inside wall panel  58 , sheet metal panel  116 , and fastener  117 , such as common nail. The construction of  FIGS. 29-32  enables a fastener or common nail to be used to attach siding  115  to a wall  11 ,  12 ,  13 ,  14  wherein the nail or fastener penetrates and holds together the siding, inside wall panel  58 , insulation  114 , and sheet metal panel  116 . The sheet metal panel  116  can provide flanges  118  that extend on opposing sides of the insulation  114  as shown in  FIG. 31 . Further, the insulation layer  114  can be grooved on one or all surfaces, providing grooves  119 . 
     FIGS. 33A-33B  show another corner construction that can optionally be used with the apparatus  10  of the present invention. Corner  120  can be constructed using two connecting panels including starting panel  121  and ending panel  122 . Standard dimension full length panels  18  can be connected to panels  121 ,  122  at respective Z shaped portions  137 ,  142  (see  FIG. 33B ). Z shaped portions  137 ,  142  can be of the same configuration as the Z shaped portions of a full length panel  18  (see  FIG. 5 ). Upper longitudinal beams  35  can be attached to the top of panels  18 ,  121 ,  122 ,  18  (see arrows  131 ,  132  in  FIG. 33A ). Lower longitudinal beams  36  can be connected to the bottom of connected panels  18 ,  121 ,  122 ,  18 . 
   Outside L-shaped panel  123  can be attached (e.g. with fasteners  38 ) to the assembly of panels  18 ,  121 ,  122 ,  18  and beams  35 ,  36  by engaging outside panels  134 ,  141  as indicated by arrow  126  in  FIG. 33A . Panel  123  has 20 flanges  124 , 125  that form an angle of about ninety degrees (90°). 
   Inside L-shaped panel  127  can be attached to the assembly of beams  35 ,  36  and panels  18 , by attaching (e.g. with fasteners  38 ) to beams  35 ,  36  as indicated by arrow  25   130  in  FIG. 33A . Because flange  136  is shorter (e.g. 1 inch) than the width (e.g. 3½ inches) of beams  35 ,  36  a gap  147  (e.g. 2½ inches) is provided so that electrical wiring can be routed through corner  120 . Inside L-shaped panel  127  is formed of flanges  128 ,  129  that intersect at an 30 angle of about ninety degrees (90°). 
   An inside wall veneer can be attached to a building  10  that employs corner  120 . In  FIG. 33B , veneer panels  133  (e.g. Sheetrock®) are shown attached to an assembly of panels  18 ,  121 ,  122 ,  123 ,  127 ,  18  and beams  35 ,  36 . 
   Starting panel  121  is comprised of outside panel  134  and transverse end panels  135 ,  138  attached respectively to opposing ends of panel  134 . Panel  135  has flange  136  that is generally parallel to panel  134 . Panel  138  connects to panel  134  with Z shaped portion  137 . Panel  138  connects to flange  139 . Flange  139  connects to flange  140 . Flange  139  is generally parallel to panel  134 . At corner  120 , inside veneer panels  133  (e.g. wood paneling, Sheetrock®, etc. attach to flanges  129  and  139 . 
   Ending panel  122  provides an outside panel  141  that can be dimensioned to satisfy any outside wall dimension that is specified, for example, by an architect. Typically, the outside wall panels  133  selected during construction are of a standard four by eight (4′×8′) sheet size. Paneling such as wood paneling, plywood, Sheetrock®, are all typically provided in four by eight (4′×8′) foot sheets. Ideally, a wall is sized so that the inside panels  133  (sized four by eight feet) will exactly fit without having to cut a panel  133 . However, an architect might select a dimension that requires an inside wall panel  133  to be cut. In such a situation, standard full length panels  18  can be used in combination with starting panel  134  to provide any specified wall dimension. Any extra dimension that is required after a starting panel  121  and a number of standard width panels  18  are erected, can be supplied by a custom sized or cut end panel  122 . Ending panel  122  can be manufactured to any dimension, or can be oversized and then cut in the field to fit by cutting outside panel  141 . 
   Ending panel  122  provides Z shaped portion  142 , transverse end panel  143 , flange  144  (generally parallel with outside panel  141 ) and flange  145  that forms an angle of about ninety degrees with outside panel  141 . 
   Arrow  146  in  FIG. 33A  illustrates the assembly of ending panel  122  to starting panel  121 . Fasteners  38  can be used as needed to assemble the panels  121 ,  122 , beams  35 ,  36 , outside ell shaped panel  123 , and inside ell shaped panel  128 , and inside wall panels  133 .
