Abstract:
A modular form panel and a method of employing the same are provided for use when forming a rectilinear concrete column form. The form panel comprises a first side edge and a second side edge, with the first side edge having a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. The form panel also includes a top edge and a bottom edge extending between the first and second side edges, and has a generally planar interconnecting skin, with the skin having a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. Thus, a plurality of like panels may be arranged to define a rectilinear column form of predetermined cross-sectional dimensions by securing the first edge of the panel to the skin of an adjacent like panel by attaching a selected one of the first edge gage lines to a selected one of the skin gage lines on the adjacent like panel.

Description:
FIELD OF THE INVENTION 
     The present invention relates to form panels for forming concrete columns and to a forming system employing such form panels. 
     BACKGROUND OF THE INVENTION 
     In concrete construction modular forming systems for forming concrete walls are generally well known in the art. Modular forming systems for concrete walls are generally favored by contractors because such modular systems permit the rapid assembly, disassembly, and reuse of the forms, thus offering significant savings in terms of time, labor, and materials. Moreover, the use of a discrete number of pre-manufactured wall form sections permits the construction of wall having different height, length, and thickness simply by choosing modular sections of the desired size. 
     When constructing concrete buildings or other structures, it would be desirable to extend the cost savings afforded by modular construction of wall forms to the modular construction of column forms. Modular construction of concrete column forms would cut waste by saving concrete due to the fact that each individual column could be constructed to its own specifications, rather than overbuilding some of the columns to take advantage of existing form sizes. Ideally, such a modular column form system would minimize surface irregularities, which in turn improves the concrete cover over the reinforcing steel. Such a modular column form would also accommodate high pour pressures with minimal external stiffening or reinforcement. 
     SUMMARY OF THE INVENTION 
     In accordance with a first aspect of the invention, a modular form panel is provided for use when forming a rectilinear concrete column form. The form panel comprises a first side edge and a second side edge, with the first side edge having a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. The form panel also includes a top edge and a bottom edge extending between the first and second side edges, and has a generally planar interconnecting skin, with the skin having a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. Thus, a plurality of like panels may be arranged to define a rectilinear column form of predetermined cross-sectional dimensions by securing the first edge of the panel to the skin of an adjacent like panel by attaching a selected one of the first edge gage lines to a selected one of the skin gage lines on the adjacent like panel. 
     In further accordance with a preferred embodiment, the first side edge of the panel includes an edge stiffener. Preferably, the edge stiffener is an L-shaped member, and further may be widened or otherwise be constructed to form an abutting surface adapted for abutting contact with the skin of the adjacent panel. 
     Still preferably, the panel first edge gage lines are spaced apart a first distance and the skin gage lines are spaced apart a second distance, with the first distance being less than the second distance. In a preferred embodiment, the panel first edge gage lines are spaced apart a distance of between about 2 inches and about 3 inches, and the skin gage lines are spaced apart a distance of between about 4 inches and about 6 inches. 
     When the panel is assembled with like panels, at least one of the skin gage lines may be unused, and thus a plug may be provided which is adapted for placement in any unused attachment holes. The unused attachment holes will preferably include a countersunk portion, and the plug preferably includes a shank and a head. The head of the plug will include an end surface and will be sized to fit in the countersunk portion so that the plug head cooperates with the skin to form a generally uninterrupted planar surface. 
     The panel will preferably includes a top stiffener adjacent the top edge and a bottom stiffener adjacent the bottom edge, with the top and bottom stiffeners extending between the first and second side edges. The panel may also include at least one intermediate stiffener extending between the first and second side edges. Preferably, each of the top, bottom, and intermediate stiffener are Z-shaped members, and still preferably the Z-shaped members may be substantially identical. Each of the attachment holes may be positioned or located so as to extend through one of the stiffeners. 
     In accordance with a second aspect of the invention, an adjustable modular form system is provided for constructing a rectilinear column form having a desired one of a plurality of available cross-sectional dimensions. The system comprises a plurality of form panels, with each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin. The first side edge of each panel includes a plurality of attachment holes arranged in a plurality of vertically oriented gage lines, and the skin of each panel includes a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. Accordingly, upon attaching the first side edge of each of the panels along a selected one of the side edge gage lines to the skin of its adjacent panel along a selected one of the skin gage lines the panels are arranged to create the generally rectilinear column form having the desired cross-sectional dimensions. 
     In accordance with another aspect of the invention, a concrete column form comprises a plurality of form panels, with each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin. Adjustable joining means are provided for adjustably joining the panels to each other to produce a generally rectilinear column form having a desired one of a plurality of rectilinear cross-sections. The adjustable joining means is defined in part by a portion of the first side edge of each of the panels and a cooperating portion of the skin of an adjacent panel. 
     In accordance with yet another aspect of the invention, an adjustable forming system is provided for constructing a concrete column form having a desired one of a plurality of available cross-sectional dimensions. The system comprises a plurality of form panels, with each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin. The first side edge of each of the form panels is adapted to define a plurality of attachment lines, and the skin of each of the panels also is adapted to define a plurality of attachment lines. Accordingly, the column form having the desired cross-sectional dimensions may be assembled upon securing a selected one of the first side edge attachment lines on each of the panels to a selected one of the skin attachment lines on an adjacent panel. 
     In accordance with a still further aspect of the invention, a method of constructing a concrete column form having a desired one of a plurality of available cross-sectional dimensions comprises the steps of choosing the desired cross-sectional dimension to be constructed, and providing a plurality of form panels, with each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin. Further, the first side edge of each of the panels is provided with a plurality of attachment holes arranged in a plurality of vertically oriented gage lines, while the skin of each of the panels is provided with a plurality of attachment holes arranged in a plurality of vertically oriented gage lines. A selected one of the gage lines on the first side edge of each panel is secured to a selected one of the gage lines on the skin of an adjacent panel, thereby creating the concrete column form having the desired cross-sectional dimension. 
     Preferably, the step of providing the plurality of form panels includes the steps of providing a first set of form panels and providing a second set of form panels, with the first set of form panels having a first spacing between the first side edge gage lines and a second spacing between the skin gage lines, and with the second set of form panels having a third spacing between the first side edge gage lines and a fourth spacing between the skin gage lines. The method may further include the steps of selecting a pair of form panels form the first set of form panels, selecting a set of form panels of from the second set of form panels, and placing a form panel from each set between a pair of form panels from the other set. 
     In accordance with an additional aspect of the invention, a method of constructing a concrete column form having a desired one of a plurality of available cross-sectional dimensions comprises the steps of choosing the desired cross-sectional dimension to be constructed, and providing a plurality of form panels, with each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin. A plurality of attachment portions is provided on the first side edge of each of the panels, and a plurality of attachment portions is provided on the skin of each of the panels. A selected one of the first side edge attachment portions of each of the panels is adjustably secured to a selected one of the attachment portions on the skin of an adjacent panel, thereby creating the concrete column form having the desired cross-sectional dimension.

     DETAILED DESCRIPTION OF THE INVENTION 
     The embodiment described herein is not intended to be exhaustive or to limit the scope of the invention to the precise form disclosed. The following embodiment has been chosen and described in order to best explain the principles of the invention and to enable others skilled in the art to follow its teachings. 
     Referring now to FIG. 1 of the drawings, a plurality of modular form panels constructed in accordance with the teachings of the present invention and which are generally referred to by the reference numeral  10  are shown assembled in adjacent relationship to form a section of a column form  12  for forming a concrete column (not shown) by pouring uncured concrete into a cavity  13  enclosed on four sides by the panels. 
     Referring now to FIGS. 2,  3 ,  3 A,  4 ,  5  and  6 , a single form panel  10  is shown. Although four such form panels  10  may be assembled to form the column form  12  illustrated in FIG. 1, it will be understood that in the first embodiment of the invention the four form panels  10  are substantially identical, and thus for the sake of brevity only a single form panel  10  will be described hereinafter in detail. The form panel  10  includes a pair of side edges  14 ,  16 , interconnecting top and bottom edges  18 ,  20 , and an interconnecting and generally planar skin  22 . 
     The side edge  14  includes a first set of holes  24  including holes  24   a ,  24   b ,  24   c  and  24   d  arranged along a first vertical gage line  26 , and further includes a second set of holes  28  including holes  28   a ,  28   b ,  28   c , and  28   d  arranged along a second vertical gage line  30 . It will be understood that, although four holes are shown in the gage line  26  ( 24   a - 24   d ) and four holes are shown in the gage line  30  ( 30   a - 30   d ), more or fewer holes may be used in each of the gage lines  26 ,  30 . Further, additional gage lines (not shown) may be used. It will further be understood that not all of the holes in each of the gage lines  26 ,  30  need actually be used when assembling the column form  12 . 
     The planar skin  22  includes a first set of holes  32   a  and  32   b , which are arranged along a vertical gage line  34 . The planar skin  22  also includes a second set of holes  36   a  and  36   b , which are arranged along a second vertical gage line  38 . The planar skin  22  further includes a third set of holes  40   a  and  40   b , which are arranged along a third vertical gage line  42 , and finally includes a fourth set of holes  44   a  and  44   b , which are arranged along a fourth vertical gage line  46 . It will be understood that, although two holes are shown in each of the gage lines  34 ,  38 ,  42 , and  46 , more or fewer holes may be used in each of the gage lines, and it will further be understood that the planar skin  22  may have additional gage lines (not shown). It will also be understood that if additional holes are provided in each of the gage lines, that not all of the holes need be used when assembling the column form  12 . 
     Referring now to FIGS. 2,  3  and  6 , the side edge  14  may include a stiffener  48 . The stiffener  48  includes is a generally L-shaped member having a pair of legs  50 ,  52 . At least a portion, if not all, of the leg  50  will generally define a widened face  54  which will abut the skin  22  of an adjacent and similar panel  10  in the manner to be described in greater detail below. It will be noted that in the preferred embodiment the sets of holes  24 ,  28  are defined in the leg  50  of the stiffener  48 . The side edge  16  may also include a stiffener  53 , in which a plurality of holes  54  may be defined for purposes of handling, etc. Alternatively, the stiffener  53  may be constructed so as to have a widened face similar to the stiffener  48  such that two (2) rows of holes  54  may be provided for purposes of permitting the attachment of other elements or components used in the construction process as may be contemplated by those skilled in the art. 
     It will be noted when viewing either of FIGS. 1,  2 ,  5  or  6  that the gage lines  26 ,  30  on the side edge  14  are spaced apart a distance A, while the gage lines  34 ,  38 ,  42  and  46  on the skin  22  are spaced apart a distance B. In accordance with a preferred embodiment, the distances A and B are not equal. In further accordance with a preferred embodiment, the distance A is less than B, with the distance A measuring about two (2) inches and the distance,B measuring about four (4) inches. As will be outlined in greater detail below with respect to a second preferred embodiment of the invention, other distances may also be used. 
     Referring now to FIGS. 1 through 6, the panel  10  may further include one or more lateral or horizontal stiffeners  56 . The stiffeners  56  may be formed of a Z-shaped section having a pair of legs  58 ,  60  and an interconnecting web  62 . It will be noted that the leg  58  of the stiffeners are disposed so as to abut the backside of the planar skin (the backside being the face of the skin facing away from the concrete to be poured). The form panels may also include a top stiffener  64  disposed along the top edge  18  and a bottom stiffener  66  disposed along the bottom edge  20 . As shown, each of the top and bottom stiffeners are formed of C-shaped members having legs of unequal length. Other stiffeners may be used. It will be understood that the panel  10  may be assembled by welding or by any other suitable attachment means. 
     Referring now to FIGS. 1 and 9, it will be noted that when the panels  10  shown therein are assembled to form the column form  12 , that at least three of the four gage lines in the skin  22  will be unused. When the panels  10  are assembled as shown in FIG. 1, then the second, third and fourth sets of holes (i.e., holes  36   a ,  36   b ,  40   a ,  40   b ,  44   a , and  44   b ) along the gage lines  38 ,  42  and  46 , respectively, will be exposed to the concrete to be poured into the cavity  13 . If left unplugged, at least a portion of the uncured concrete and/or water would seep through the respective holes. Preferably, some means is provided for plugging the respective holes. In the preferred embodiment, and referring specifically to FIG. 9 which illustrates the holes  32   a ,  36   a ,  40   a  and  44   a , each of the respective holes will include a first portion  68  which extends through the skin  22  and a second portion  70  which extends through the leg  58  of the stiffener  56 . It will be noted that the first portion  68  is countersunk (i.e., the first portion  68  has a diameter larger than the diameter of the second portion  70 ). Consequently, a ledge or annular seat  72  is formed at the interface between the first portion  68  and the second portion  70 . 
     Also shown in FIG. 9 is a plug  74  having a shank  76  sized to fit into the second portion  70 . The plug  74  also includes a head  78  having a planar end surface  80 . The head  78  is sized to fit into the first portion  68 , such that the head is seated on the annular seat  72 . Accordingly, the end surface  80  cooperates with the surface of the skin  22  to form a generally continuous and uninterrupted planar surface  82  facing into the cavity  13 . It will be understood that the planar surface  82  will improve the surface characteristics of the concrete column formed in the cavity  13  due to the fact that no portion of the plug  74  will extend past the skin  22 . 
     In operation, four of the panels  10  (hereinafter labeled panels  10   a ,  10   b ,  10   c  and  10   d  for clarity) are placed as shown in FIGS. 1 and 7. It will again be understood that each of the panels  10  shown in FIGS. 1 and 7 are substantially identical. When so assembled, the side edge  14   a  of the first panel  10   a  will be disposed adjacent the skin  22   b  of the adjacent panel  10   b , and so on (i.e., the side edge  14   b  of panel  10   b  will be disposed adjacent the skin  22   c  of the adjacent panel  10   c , the side edge  14   c  of the panel  10   c  will be disposed adjacent the skin  22   d  of the adjacent panel  10   d , and the side edge  14   d  of the panel  10   d  will be disposed adjacent the skin  22   a  of the adjacent panel  10   a ). Using a plurality of bolts  84  (which may be any suitable fastener of the type commonly employed in the assembly of forms), the panels  10   a - 10   d  may be secured to each other in a variety of configurations so as to define a cavity  13  having any one of a desired number of available cross-sectional dimensions. Note that, in a preferred embodiment, the panel skin may have a thickness of about {fraction (3/16)} of an inch, and the stiffeners may have a thickness of about {fraction (3/16)} to about ¼ of an inch. 
     When configured as shown in FIG. 7, the gage line  30   a  on the side edge  14   a  of the panel  10   a  is secured to the skin  22   b  of the panel  10   b  along the gage line  34   b . Similarly, the gage line  30   b  on the side edge  14   b  of the panel  10   b  is secured to the skin  22   c  of the panel  10   c  along the gage line  34   c . Similarly, the gage line  30   c  on the side edge  14   c  of the panel  10   c  is secured to the skin  22   d  of the panel  10   d  along the gage line  34   d . Finally, the gage line  30   d  of the panel  10   d  is secured to the skin  22   a  of the panel  10   a  along the gage line  34   a.    
     Referring now to FIGS. 10 a - 10   h , it will be understood that the cross-sectional dimensions of the cavity  13  can be varied widely simply by selecting a desired cross-section for the cavity  13 , and then choosing which gage lines  26 ,  30  shall be used on the side edge  14  of the panels  10 , and which gage lines  34 ,  38 ,  42  and  46  shall be used on the skin  22  of the next adjacent panel. As would be evident to those skilled in the art, a variety of square cross-sectional configurations may be achieved, with a representative example of a square cross-sectional configuration being shown in FIG.  7 . As would further be evident to those of skill in the art, a variety of rectangular cross-sectional configurations may be achieved as well, with a representative rectangular cross-sectional configuration being shown in FIG.  8 . 
     It will be understood that a plurality of like panels  10  assembled into a column form  12  may be placed on top of the column form  12  shown in FIG. 1, such that a column of various vertical dimensions may be formed. 
     Referring now to FIGS. 11-14, a form panel assembled in accordance with an alternate embodiment of the invention is shown and is referred to by the reference numeral  110 . The panel  110  is in many respects similar to the panel  10  described above, and therefore all like elements will have the same reference numeral, albeit increased by an increment of  100 . Four (4) of the panels  110  may be used in conjunction with each other, or alternatively the panels  110  may be used as shown in FIG. 8 a , with a pair of the panels  110  being disposed between a pair of the panels  10  in alternating fashion. The form panel  110  includes a pair of side edges  114 ,  116 , interconnecting top and bottom edges  118 ,  120 , and an interconnecting and generally planar skin  122 . The side edge  114  includes first and second sets of holes  124 ,  128  arranged along a pair of vertical gage lines  126 ,  130 . The planar skin  122  includes a plurality of holes arranged along four vertical gage lines  134 ,  138 ,  142 , and  146 . Each of the panels  110  may be provided with a plurality of Z-shaped stiffeners  156  as well as top, bottom and side stiffeners  164 ,  166 , and  153 , respectively. 
     It will be noted that the gage lines  126 ,  130  on the side edge  114  are spaced apart a distance AA, while the gage lines  134 ,  138 ,  142  and  146  on the skin  122  are spaced apart a distance BB. Again, the distances AA and BB need not be equal, and preferably are unequal. In the alternate embodiment, the distance AA is less than BB, with the distance AA measuring about three (3) inches and the distance BB measuring about six (6) inches. The panel  110  is preferably substantially similar to the panel  10  in all other respects. 
     It will be noted that the panels  10  may generally be referred to as “Commercial” panels, while the panels  110  may generally be referred to as “Civil” panels. Each of the Commercial and civil panels may be assembled in a variety of nominal widths ranging from about, for example, twenty four inches to about, for example, forty eight inches. The panels  10 ,  110  will typically have vertical dimensions of about forty eight inches, and as outlined above can be stacked to form columns of varying vertical dimensions. The column form  12  assembled using the panels will exhibit a very high acceptable pour pressure, exceeding 2000 psf. 
     Referring now to Tables A through L, Table A illustrates eight different groupings of possible form assembly arrangements, with the groupings shown therein being labeled as Groups I through VIII. For example, Group I illustrates the cross-sectional dimensions achievable when bolting a nominal twenty four inch (24″) commercial panel  10  to a like panel, using any one of the possible gage line combinations illustrated in the corresponding FIGS. 10A through 10H. Group II illustrates the possible cross-sectional dimensions achievable when bolting a nominal twenty four inch (24″) civil panel  110  to a twenty four inch (24″) commercial panel  10 . 
     Group III illustrates the cross-sectional dimensions achievable when bolting a nominal thirty six inch (36″) commercial panel  10  to a like panel, using any one of the possible gage line combinations illustrated in the corresponding FIGS. 10A through 10H, while Group IV illustrates the possible cross-sectional dimensions achievable when bolting a nominal thirty six inch (36″) civil panel  110  to a thirty six inch (36″) commercial panel  10 . 
     Group V illustrates the cross-sectional dimensions achievable when bolting a nominal thirty six inch (36″) civil panel  110  to a like panel, using any one of the possible gage line combinations illustrated in the corresponding FIG. 10A through 10H, while Group VI illustrates the possible cross-sectional dimensions achievable when bolting a nominal thirty six inch (36″) commercial panel  10  to a thirty six inch (36″) civil panel  110 . 
     Finally, Group VII illustrates the cross-sectional dimensions achievable when bolting a nominal forty eight inch (48″) civil panel  110  to a like panel, using any one of the possible gage line combinations illustrated in the corresponding FIGS. 10A through 10H, while Group VIII illustrates the possible cross-sectional dimensions achievable when bolting a nominal forty eight inch (48″) commercial panel  10  to a forty eight inch (48″) civil panel  110 . Each of the resulting cross-sections shown in Table A are generally square. 
     As would be known to those of skill in the art, the conventional size adjustment increments of civil form panels are generally referred to in terms of three inch (3″) increments, while the conventional size adjustment increments of commercial form panels are generally referred to in terms of two inch (2″) increments. It is of course understood that other size increments may be desired in some applications. 
     Tables B through K illustrate a number of possible form assembly arrangements, including possible rectangular arrangements. The tabular arrangements are again achieved by selecting which of the gage lines are used on the four panels employed, and by varying the panels chosen (i.e., four civil panels, four commercial panels, or alternating two panels from one type with two panels of another type). Again, the sizes are achieved by selecting which of the gage lines will be employed as shown in FIGS. 10A through 10H. 
     Finally, Table L illustrates the number of different form dimensions available using the listed panel combinations, it being understood that there may be some duplication of form sizes.
