BACKGROUND OF THE INVENTION




1. Field of the Invention




The subject invention relates to devices for installing and supporting building components and, more particularly, to a spacer and support apparatus for supporting roof and floor trusses.




2. Description of the Invention Background




A truss is a rigid framework of wooden or metal beams designed to support a structure, such as a roof. Trusses may also be employed to span between opposing support walls to create a floor supporting structure within a building. A truss system for supporting a floor may comprise a collection of trusses that are arranged adjacent to each other and span the distance between two or more support walls. Local building codes and structural design requirements generally govern the amount of spacing permitted between each truss. When anchored to the support walls, the tops of the trusses are substantially co-planar with each other to enable floor or roof decking materials to be attached thereto.




Roof trusses may be provided in a variety of different shapes and sizes depending upon the building design. Although some roof truss systems provide a plurality of planar, horizontally disposed, support surfaces for buildings with flat roof systems, many buildings have roofs that have planar portions that are not horizontally disposed. For example, many residential buildings have peaked roofs wherein the roof surface comprises a pair of angled planes that intersect to form the roof crown or peak. Flat sheathing material is attached to the trusses to form a planar roof surface and roofing material is then affixed to the sheathing. Trusses may be fabricated on site from appropriate material such as wood, metal, etc. However, it is common practice for trusses to be fabricated off-site by an entity that specializes in the fabrication of such building components. The prefabricated trusses are then shipped to the building site and anchored in place to the support structures. Such support structures may comprise concrete block walls, stud walls, etc.




A truss typically includes a bottom member commonly referred to as the “bottom chord”. The bottom chord is the member that is supported on and anchored to the top of the support walls. Trusses typically also include two or more top chords that are attached to the bottom chord. In a typical “peak roof” truss, two top chord members are each attached to one end of the bottom chord and angle upward at a desired pitch. The other ends of each top chord are connected together to form the roof peak. A portion of each top chord may extend beyond the bottom chord to form a desired amount of overhangs that extend beyond the support walls. Similarly, in other truss arrangements, the bottom chord may extend beyond the support walls in a cantilevered fashion. A variety of braces or web members extend between the top chords and the bottom chord to provide the roof with a desired load capacity.




Trusses are commonly installed by standing the bottom chords of the trusses on edge on the support structures (walls) such that they span between the parallel walls. The ends of the bottom chords are then anchored to the support walls by screws, nails, or other appropriate anchors. A plurality of trusses are arranged in a side-to side configuration along the tops of the support walls. In some truss arrangements, the truss has a greater height dimension than a width dimension. Thus, prior to attaching the sheathing materials, a truss that is supported only at its bottom by its attachment to supporting walls can be prone to topple over on its side. Such toppling over of even one truss can result in all of the trusses falling over similar to a row of dominos which can cause injury to construction personnel and damage the trusses and other building components.




A variety of bracing devices have been constructed for supporting trusses during installation. For example, U.S. Pat. No. 3,875,719 to Menge, U.S. Pat. No. 4,080,771 to Weller, U.S. Pat. No. 4,490,956 to Placio et al., U.S. Pat. No. 4,704,829 to Baumaker, Jr., U.S. Pat. No. 5,161,345 to Sobjack, Sr., U.S. Pat. No. 5,551,200 to Krug and U.S. Pat. No. 5,606,837 to Holizlander all disclose devices which purport to solve such problems. However, many of such devices require that the bracing element be fastened to the respective truss member by a separate fastener before any lateral supporting of the truss is achieved. Still others, while providing a modicum of lateral support to the trusses prior to affixing the brace devices to the trusses with mechanical fasteners (screws, nails, etc.), are difficult to manufacture. Other such devices fail to provide adequate support between adjacent truss members and are not suited for attachment to a variety of different truss materials. Still some other devices employ teeth that must be hammered into the truss and, if not installed properly, can lead to splintering and truss damage. Furthermore, such toothed devices will not work with steel trusses and other building components fabricated from steel. Yet other devices, while effective for supporting trusses during their installation, must be removed before roofing sheathing or floor decking can be installed.




Thus, there is a need for a spacer bar for trusses and the like that is relatively easy to manufacture and install.




There is a further need for a spacer bar that will rigidly support trusses in position during installation of additional fasteners.




Yet another need exists for a spacer bar with the above-mentioned characteristics that does not have to be removed prior to installing roof or floor decking materials.




Still another need exists for a spacer bar that can be used to support a variety of different structural components regardless of the type of material from which they are constructed.




SUMMARY OF THE INVENTION




In accordance with one form of the present invention, there is provided a spacer bar that comprises an elongated planar brace member that has a planar upper surface, a planar lower surface, a first end and a second end. A first tab that has a first flared lower portion perpendicularly protrudes from the planar lower surface of the elongated planar brace member. A second tab perpendicularly protrudes from the lower surface of the elongated planar brace member and is spaced from the first tab a first predetermined distance. A third tab perpendicularly protrudes from the lower surface of the elongated planar brace member and is spaced from the second tab a second predetermined distance. A fourth tab perpendicularly protrudes from the lower surface of the elongated planar brace member and is spaced from the third tab a third predetermined distance. At least one of the third and fourth tabs has a flared lower portion. In one embodiment, a first lateral side member protrudes perpendicularly downward from a first lateral portion of the brace member and extends between the second tab and the third tab. Also in this embodiment, a second lateral side member protrudes perpendicularly downward from a second lateral side portion of said planar brace member and extends between the second tab and the third tab. A third lateral side member protrudes perpendicularly downward from a third lateral side portion and extends from the first end to the first tab. A fourth lateral side member protrudes perpendicularly downward from a fifth lateral side portion and extends from the first end to the first tab. A fifth lateral side member protrudes perpendicularly downward from a fifth lateral side portion and extends from the second end to the fourth tab. A sixth lateral side member protrudes perpendicularly downward from a sixth lateral side portion and extends from the second end to the fourth tab.




The subject invention may also include fifth and sixth tabs that perpendicularly protrude from the lower surface of the planar brace member. In one embodiment, the second tab is spaced from the first tab such that the distance therebetween is equal to or slightly greater than the cross-sectional thickness of a first structural member to be inserted therebetween. Similarly, the fourth tab is spaced from the third tab such that the distance therebetween is slightly greater than or equal to the cross-sectional thickness of a second structural member to be inserted therebetween. Likewise, the sixth tab is spaced from the fifth tab such that the distance therebetween is slightly greater than or equal to the cross-sectional thickness of a third structural member to be inserted therebetween. Reinforcing members may be provided between the second and third tabs and the fourth and fifth tabs to provide the spacer bar with additional rigidity and downwardly protruding lateral side members may extend between the second and third tabs and the fourth and fifth tabs. In addition, lateral side tabs may extend from a first end of the brace member to the first tab and additional tabs may extend from the second end of the brace member to the sixth tab.




Another embodiment of the present invention comprises a spacer bar that includes an elongated planar brace member that has a planar upper surface and a planar lower surface. A first portion is punched from the elongated planar brace member and is bent substantially perpendicular to the lower planar surface to form a first tab. A second portion is punched from the elongated planar brace member and is bent substantially perpendicular to the lower planar surface to form a second tab spaced from the first tab such that a first planar portion of the planar brace member extends therebetween. A third portion is punched from the elongated planar brace member and is bent substantially perpendicular to the lower planar surface to form a third tab that is spaced from the second tab. A fourth portion is punched from the elongated planar brace member and is bent substantially perpendicular to the lower planar surface to form a fourth tab that is spaced from the third tab to define a second planar portion of the elongated brace member therebetween.




The subject invention also comprises a method for bracing a first truss relative to a second truss in a desired spaced-apart relationship on a support member. The method includes providing a planar brace member that has a first pair of integral clamping tabs protruding therefrom. The first pair of integral clamping tabs are spaced from each other a first distance that is greater than by a predetermined magnitude or is equal to a cross-sectional thickness of the first truss. The brace member also has a second pair of integral clamping tabs protruding therefrom. The second clamping tabs are spaced from each other a second distance that is greater than by a predetermined magnitude or is equal to a cross-sectional thickness of the second truss. The method further includes placing the first truss on edge on the support member and placing the second truss on edge on the support member a predetermined distance from the first truss. The first clamping tabs are forced into clamping engagement with the first truss member and the second clamping tabs are forced into clamping engagement with the second truss.




It is a feature of the present invention to provide a spacer bar for structural building components such as trusses and the like that is easy to manufacture and install.




It is another feature of the present invention to provide a spacer bar that will rigidly support trusses in position during installation of fasteners such as nails, screws and the like to further affix the spacer bar to the trusses.




Yet another feature of the present invention is to provide a spacer bar with the above-mentioned characteristics that does not have to be removed prior to installing roof or floor decking materials.




Still another feature of the present invention is to provide a spacer bar that can be used to support a variety of different structural components regardless of the type of material from which they are constructed.




Yet another feature of the present invention is to provide a means for supporting trusses or other building components on edge prior to fastening such components together. Thus, the present invention results in improved safety, because the installer is able to obtain the requisite tools and fasteners without having to simultaneously support the truss or building component in a desired orientation.




Accordingly, the present invention provides solutions to the shortcomings of prior truss spacer devices and braces. The subject invention is easy to manufacture and install. The subject invention may be installed on a plurality of trusses without risk of the trusses toppling as additional fasteners are installed. Those of ordinary skill in the art will readily appreciate, however, that these and other details, features and advantages will become further apparent as the following detailed description of the embodiments proceeds.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION




Referring now to the drawings for the purposes of illustrating the present embodiments of the invention only and not for the purposes of limiting the same, there is shown a spacer bar


20


of the present invention for use in connection with structural building components such as roof trusses, floor trusses, etc.

FIG. 1

depicts two spacer bars of the present invention used in connection with a plurality of conventional roof trusses (


10


,


210


,


310


,


410


). The reader will appreciate that truss


10


may comprise a bottom chord


12


and a pair of upper chords


14


that are attached at one of their respective ends to the bottom chord


12


at a desired pitch. The other ends of the upper chords


14


are attached together to form the peak


19


. A plurality of appropriate web braces


16


are attached between the bottom chord


12


and the upper chords


14


. Similarly, truss


210


includes a bottom chord


212


, upper chords


214


, web braces


216


and a peak


219


. Truss


310


includes a bottom chord


312


, upper chords


314


, web braces


316


and a peak


319


. Truss


410


includes a bottom chord


412


, two upper chords


414


, web braces


416


and a peak


419


. As will be discussed below, the spacer bars


20


may be installed such that they are located on the upper one third of the top chords as shown in FIG.


1


. The reader will appreciate, however, that the spacer bars


20


could be installed at other locations on the top chords and, for longer spanning trusses, multiple rows of spacer bars could be used. It will be further understood that the present spacer bar


20


could also be effectively installed on the lower chords of trusses instead of, or in addition to, installing the spacer bars


20


on the upper chords of the trusses.




The skilled artisan will further appreciate that the spacer bar


20


of the present invention may have utility beyond use in connection with roof and floor truss components. Furthermore, as the present detailed description proceeds, the reader will appreciate that the spacer bar


20


of the present invention can be successfully used in connection with a variety of different building components that are fabricated from various materials such as metal, wood, etc. Thus, although the present invention is described herein in connection with wooden roof trusses (


10


,


210


,


310


,


410


), the protection afforded thereto should not be limited solely to use in connection with such components.





FIGS. 1-12

, illustrate one embodiment of the subject invention constructed for supporting three roof trusses (


10


,


210


,


310


) in a predetermined spaced-apart relationship. More particularly and with reference to

FIGS. 2-9

, the spacer bar


20


includes an elongated planar brace member


22


that has a planar upper surface


24


and a planar lower surface


26


. Brace member


22


may be fabricated from metal such as cold rolled steel, hot rolled steel, stainless steel and aluminum. However, other materials such as wood, plastic, etc. could be successfully used. As can also be seen in

FIGS. 1-5

, the elongated planar brace member


22


has a first end


28


and a second end


29


.




In this embodiment, a first portion


30


adjacent the first end


28


is punched through the elongated planar brace member


22


to form a first tab


32


. Those of ordinary skill in the art will appreciate such punching operation may be performed utilizing conventional metal punching techniques and apparatuses. Although in this embodiment, tab


32


is integrally formed with the elongated planar brace member


22


, the reader will appreciate that the tab


32


may be provided in different shapes and comprise a separate piece of material welded or otherwise attached to the planar lower surface


26


. To facilitate attachment of the tab


32


to the truss, the tab


32


may be provided with one or more fastener holes


33


therethrough for receiving an appropriate fastener (i.e., screw, nail, etc.). See FIG.


6


. As can be seen in

FIG. 10

, the first tab


32


is bent downward from the planar lower surface


26


such that it extends substantially perpendicular thereto (i.e., angle “A” is approximately 90°). As can also be seen in

FIGS. 10 and 10A

, the first tab


32


has an upper portion


34


and a flared or arcuate lower portion


36


. As used herein the term “flared” encompasses any curved or flared portion that is not co-planar with the upper portion


34


of the tab


32


. For example, tab


32


may protrude from the lower planar surface a distance “B” which may be 1 inch long and the lower portion may be formed at a radius “C” of ¾ inch. In the alternative, the lower portion


34


may be bent at an angle relative to the upper portion


34


. Thus, as used herein, the term “flared” is meant to encompass both such arrangements in addition to any arrangement wherein the lower portion


36


is not substantially coplanar with the upper portion


34


.




The subject spacer bar


20


also includes a second portion


40


that is punched from the elongated planar brace member


22


to form a second tab


42


that is spaced a first “fixed” predetermined distance “D” from the first tab


32


. The term “fixed” as used herein means that the position of the second tab


42


relative to the first tab cannot be selectively changed. The second tab


42


is also bent at an angle “E” that is substantially 90° to the planar lower surface


26


of the brace member


22


. The second tab


42


has an upper portion


44


and a flared lower portion


46


. The flared lower portion


46


is constructed in the same manner as the flared lower portion


36


of the first tab


32


. However, flared lower portions (


36


,


46


) are bent in opposite directions to facilitate installation of the spacer bar


20


onto a structural building component such as the upper chord


14


of a roof truss


10


. To facilitate attachment of the second tab


42


to the truss, one or more fastener holes


43


are provided through the tab


42


for receiving an appropriate fastener therethrough. See FIG.


10


. As can be seen in

FIGS. 10 and 10A

, a first planar portion


47


of the planar brace member


22


extends between the first tab


32


and the second tab


42


. One or more fastener openings


48


may be provided through the first planar portion


47


to enable conventional first fasteners


49


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


20


to the truss


10


as will be described in further detail below.




Tabs (


32


,


42


) form a first pair of integral clamping tabs collectively designated as


50


. In one embodiment, the first predetermined distance “D” is slightly greater than or equal to the cross-sectional thickness “F” of the upper chord


14


of the truss


10


to be clamped thereby (i.e., “D” could range from 0-{fraction (1/16)} inch greater than distance “F”).




Also in this embodiment, a third portion


60


is punched through the elongated planar brace member


22


to form a third rectangular shaped tab


62


that is spaced from the second tab a second “fixed” predetermined distance “G”. See FIG.


5


. In this embodiment, distance “G” may be, for example, 22% inches. Third tab


62


is bent downwardly from the planar lower surface


26


such that it is substantially perpendicular thereto (angle “I” is approximately 90°). See FIG.


11


. The third tab


62


is formed in the same manner as the first tab


32


and has an upper portion


64


and a flared lower portion


66


and may have one or more fastener holes


63


therethrough. See FIG.


11


.




A fourth portion


70


is punched from the elongated planar brace member


22


to form a fourth rectangular shaped tab


72


that protrudes substantially perpendicular from the planar lower surface


26


(angle “J” is approximately 90°) and is spaced from the third tab


62


a third predetermined distance “K”. The fourth tab


72


is formed in the same manner as the second tab


42


and has an upper portion


74


and a flared lower portion


76


and may have one or more fastener holes


73


therethrough. See FIG.


11


.




Tabs (


62


,


72


) form a second pair of integral clamping tabs collectively designated as


80


. In one embodiment, the third predetermined distance “K” is equal to or slightly greater than the cross-sectional thickness “L” of the upper chord


214


of the second truss


210


to be clamped thereby (i.e., distance “K” may be from 0-{fraction (1/16)} inch greater than distance “L”).




As can be seen in

FIGS. 11 and 11A

, a second planar portion


82


of the planar brace member


22


extends between the tabs (


62


,


72


). One or more second fastener openings


84


may be provided through the second planar portion


82


to enable conventional second fasteners


86


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


20


to the upper chord


214


of a second truss


210


as will be discussed in further detail below.




A fifth portion


110


is punched from the elongated planar brace member


22


to form a fifth rectangular shaped tab


112


that is spaced from the fourth tab


72


a fourth fixed predetermined distance “M”. See FIG.


5


. Fifth tab


112


is bent downwardly from the planar lower surface


26


such that it is substantially perpendicular thereto (angle “N” is approximately 90°). See FIG.


12


. The fifth tab


112


is formed in the same manner as the first tab


32


and has an upper portion


114


and a flared lower portion


116


and may have one or more fastener holes


113


therethrough.




A sixth portion


120


is punched from the elongated planar brace member


22


to form a sixth rectangular shaped tab


122


that protrudes substantially perpendicular from the planar lower surface


26


(angle “O” is approximately 90°) and is spaced from the fifth tab


112


a fifth predetermined distance “P”. See FIG.


12


. The sixth tab


122


is formed in the same manner as the second tab


42


and has an upper portion


124


and a flared lower portion


126


and one or more fastener holes


123


therethrough.




Tabs (


112


,


122


) form a third pair of integral clamping tabs collectively designated as


130


. In one embodiment, the fifth predetermined distance “P” is equal to or greater than the cross-sectional thickness “Q” of the upper chord


314


of a third roof truss


310


(i.e., distance “p” may be approximately 0-{fraction (1/16)} inches greater than distance “Q”)




As can be seen in

FIGS. 12 and 12A

, a third planar portion


132


of the planar brace member


22


extends between the tabs (


112


,


122


). One or more third fastener openings


134


may be provided through the third planar portion


132


to enable conventional third fasteners


136


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


20


to a building component such as roof truss


314


in the manners discussed above.




The reader will appreciate that building components are spaced at predetermined intervals that may be dictated by the type of building structure and loading characteristics. In addition, many building codes require that the roof trusses for a residential building be spaced at two feet between their respective centers. Thus, in the embodiment depicted in

FIG. 2

, the distance “R” between the centers of the first and second planar portions (


47


,


82


) and the centers of the building components clamped by the first and second pairs of clamping tabs (


50


,


80


) may be


24


inches. Similarly, the distance “S” between the centers of the second planar portion


82


and the third planar portion


132


may also be


24


inches (distance “T” may be 48 inches). The reader will readily appreciate however, that distances could have a variety of other magnitudes.




The reader will further appreciate that the tabs (


32


,


42


,


62


,


72


,


112


,


122


) are substantially rigid with respect to the planar brace member


22


. However, if the spacer bar


20


is fabricated from the above-identified material, such material enables the tabs to flex slightly when the truss component is inserted therebetween. For example, during installation, the tabs (


32


,


42


) may each flex outward (represented by arrows “U” in FIG.


10


). Thus, the term “rigid” as used herein with respect to tabs (


32


,


42


,


62


,


72


,


112


,


122


), means that such tabs cannot be repositioned longitudinally along the brace member


22


but rather remain affixed thereto while permitting their respective lower portions to flex slightly for installation purposes. That term also encompasses tabs that do not flex and are unable to be moved longitudinally along the brace member


22


.




To provide the spacer bar


20


with laxial rigidity between the first pair of clamping tabs


50


and the second pair of clamping tabs


80


, a first reinforcing member


90


may be centrally disposed in a portion


25


of the elongated planar brace member


22


that extends between the second tab


42


and the third tab


62


. In this embodiment, the first reinforcing member


90


comprises a first reinforcing rib segment


92


that is integrally formed in the portion


25


. More particularly and with reference to

FIGS. 4 and 5

, the first reinforcing rib segment


92


may comprise an arcuate rib that is centrally disposed in the portion


25


. For example, in an embodiment wherein distance G′ is 22½ inches, the first reinforcing rib segment


92


may be


21


inches long (distance G″). See

FIGS. 3 and 4

. In an embodiment wherein the elongated planar brace member


22


is 3.5 inches wide (distance X), the first reinforcing rib segment


92


may be 1.5 inches wide (distance X′) and be ¾ inches deep (distance X″). The rib segment


92


may be formed with radiused edges with respect to the planar upper surface


24


of the brace member


22


(i.e., distance is approximately 0.375 inches). Those of ordinary skill in the art will appreciate, however, that other shapes and sizes of reinforcing members may be formed in or attached to the planar brace member


22


to provided additional rigidity thereto without departing from the spirit and scope of the present invention.




Similarly, to provide the spacer bar


20


with laxial rigidity between in the second pair of clamping tabs


80


and the third pair of clamping tabs


130


, a second reinforcing member


140


may be centrally disposed in a portion


142


of the elongated planar brace member


22


that extends between the fourth tab


72


and the fifth tab


112


. In this embodiment, the second reinforcing member


140


comprises a second reinforcing rib segment


144


that is integrally formed in the portion


142


and is sized similarly to the first reinforcing rib


92


as described above. Those of ordinary skill in the art will appreciate, however, that other shapes and sizes of reinforcing members may be formed in or attached to the planar brace member


22


to provide additional rigidity thereto without departing from the spirit and scope of the present invention.




The use and installation of the spacer bar


20


can be understood from reference to

FIGS. 1

,


10


,


10


A,


11


,


11


A,


12


, and


12


A. In this example, a single spacer bar


20


is used to support three roof trusses (


10


,


210


,


310


) that are supported on two support walls (


18


,


18


′). As can be seen in

FIG. 1

, the bottom chords (


12


,


212


,


312


) of the trusses (


10


,


210


,


310


) are supported on edge on the support walls (


18


,


18


′). The reader will appreciate that the ends of the trusses (


10


,


210


,


310


) are also typically braced in accordance with standard practices. The center of bottom chord


12


is spaced from the center of the bottom chord


212


a desired distance that is equivalent to the distance between the center of the first planar portion


47


and the second planar portion


82


of the spacer bar


20


. Likewise, the center of bottom chord


312


is spaced from the center of bottom chord


212


a desired distance that is equivalent to the distance between the center of the second planar portion


82


and the center of the third planar portion


132


. The trusses (


10


,


210


,


310


) are anchored to the support walls (


18


,


18


′) using conventional techniques. In accordance with standard practice, one or more of the trusses are supported by one or more diagonal braces that extend between the truss and the ground or some other rigid structure. Typically, at least one of the end-most trusses is braced with a diagonal brace. It will be appreciated that such a diagonal brace (not shown) prevents that truss from toppling over. Thus, in

FIG. 1

, the truss


310


may be supported by a diagonal brace that is attached to a portion of the truss


310


and extends to the ground. Thereafter, a first spacer bar


20


is oriented relative to a portion of the upper chord of truss


10


such that the first tab


32


is adjacent side


15


of the upper chord


14


of the first truss


10


and the second tab


42


is adjacent the other side


17


of the upper chord


14


of the first truss


10


. See FIG.


10


. Similarly, the third tab


62


is adjacent side


215


of the upper chord


214


of the second truss


210


and the fourth tab


72


is adjacent the other side


217


of the upper chord


214


of the second truss


210


as shown in FIG.


11


. Likewise, the fifth tab


112


is adjacent the side


315


of the upper chord


314


of the third truss


310


and the sixth tab


132


is adjacent the other side


317


of the upper chord


314


of the third truss


310


as shown in FIG.


12


.




The upper chord


14


of the truss is inserted between the first pair of clamping tabs


50


by applying a first transverse force


11


to the first planar portion


47


. See FIG.


10


. Such force may be applied along an axis V—V that is substantially perpendicular to the upper surface of the chord


14


by hitting the upper planar portion


47


with a hammer or other appropriate tool. The reader will appreciate that, when the inside surfaces of the flared lower portion


36


of the first tab


32


and the flared lower portion


46


of the second tab


42


may, depending upon the spacing between the tabs and the thickness of the upper chord


14


, direct the tabs (


32


,


42


) slightly outward (represented by arrows “U”) to enable the upper chord


14


to be clamped between the tabs (


32


,


42


). The force is applied until the portion of the planar lower surface


26


of the brace


22


that corresponds to the first planar portion


47


contacts the upper surface of the upper chord


14


and is substantially parallel thereto. See FIG.


10


A. The reader will appreciate that when the first pair of clamping tabs


50


is initially aligned in the above-mentioned manner that the third tab


62


will be substantially adjacent to side


215


of the upper chord


214


of the second truss


210


and the fourth tab


72


will be adjacent to the other side


217


of the upper chord


214


of the second truss


210


. See FIG.


11


.




The application of the first force


11


to the first planar portion


47


may also cause the second truss


210


to be clampingly engaged between the third tab


62


and the fourth tab


72


. However, if the spacer bar


20


is not completely seated such that the lower surface of the second planar portion


82


is not contacting the upper surface of the upper chord


214


of the second truss


210


(FIG.


11


A), a second force


11


′ may be applied to the second planar portion


82


in the above-described manner. The additional force


11


′ is similarly applied to the second planar portion


82


by hammer or other tool such that it is applied along an axis W—W that is substantially perpendicular to the upper surface of the chord


214


. Such force is applied until the portion of the planar lower surface


26


of the brace member


22


contacts the upper surface of the chord


214


and is substantially parallel thereto. See FIG.


11


A.




The application of the first and second forces (


11


,


11


′) to the first and second planar portions (


47


,


82


) may also cause the third truss


310


to be clampingly engaged between the fifth tab


112


and the sixth tab


122


. However, if the spacer bar


20


is not completely seated such that the lower surface of the second planar portion


132


is not contacting the upper surface of the upper chord


314


of the second truss


210


(FIG.


12


A), a third force


11


″ may be applied to the third planar portion


132


in the above-described manner. The additional force


11


″ is similarly applied to the third planar portion


132


by hammer or other tool such that it is applied along an axis X—X that is substantially perpendicular to the upper surface of the chord


314


. Such force is applied until the portion of the planar lower surface


26


of the brace member


22


contacts the upper surface of the chord


314


and is substantially parallel thereto. See FIG.


12


A.




The reader will appreciate that, after the spacer bar


20


has been installed in the above-described manner, the trusses (


10


,


210


,


310


) will be stabilized and supported in the desired spaced-apart relationship relative to each other, to enable additional trusses to be installed without risk of trusses (


10


,


210


,


310


) toppling over, provided that at least one of the trusses has been braced with one or more diagonal braces. For installations having a large number of trusses, more than one truss is typically braced with one or more diagonal braces to prevent unwanted toppling of the trusses.




After the spacer bar


20


has been installed as described, first fasteners


49


such as screws, nails, etc. may be inserted through the first fastener openings


48


to further affix the spacer bar


20


to the first truss


10


. Additional fasteners


135


may be inserted through the fastener openings in the tabs (


34


,


44


) if desired. Similarly, the spacer bar


20


may be further affixed to the second truss


210


by inserting second fasteners


86


(nails, screws, etc.) through the second fastener holes


84


in the second planar portion


82


and fasteners


135


through at least one second fastener opening in each of the tabs (


62


,


72


). Likewise, third fasteners


136


may be inserted through third fastener holes


134


in the third planar portion


132


to affix the spacer bar


20


to the third truss


310


and, if desired, fasteners


135


may be inserted through fastener openings in the tabs (


112


,


122


).




The reader will further appreciate, however, that the spacer bar


20


of the present invention could also be installed on the trusses without the use of fasteners. That is, the spacer bar may be installed over the trusses in the above-described manner without inserting nails, screws, and etc. through the fastener holes. The spacer bar will support the trusses in the desired upright position and at the desired spacing arrangement and the sheathing or other material may be installed over the spacer bar.




After the first three trusses (


10


,


210


,


310


) have been installed, another spacer bar


20


may be employed in the above manner to support an additional truss


410


. For example, as shown in

FIG. 1

, a second spacer bar


20


is affixed between the first truss


10


and a fourth truss


310


and a fifth truss (not shown) in the manner described above. However, as can be seen in

FIG. 1

, the second spacer bar


20


is staggered from the first spacer bar


20


. After the trusses and the spacer bars


20


have been installed in the above-described manner, appropriate decking materials, roofing materials, floor materials, etc. may be affixed to the upper chords of the trusses. One method of installing the spacer bars


20


of the present invention includes locating the spacer bars on the upper one third of the upper truss chords. Those of ordinary skill in the art will further appreciate that when a truss located at an end of a structure is installed, the spacing between that end truss and the adjacent truss may sometimes be less than the relatively uniform spacing between the other trusses. The spacer bar of the present invention may be effectively employed in these situations by installing the clamping tabs on the adjacent trusses that are equally spaced from each other and cutting the portion of the brace


22


extending between the next-to-last truss and the end truss such that the spacer brace does not undesirably extend past the end truss. The end of the spacer brace


22


may then be affixed to the end truss by passing one or more fasteners (i.e., nail, screw) through the spacer brace and into the end truss. Thus, the spacer bar of the present invention can accommodate such situations wherein the spacing between the end truss and the other trusses is not the same as the spacing between the other trusses (and the sets of clamping tabs).




The reader will appreciate that the flared ends of the tabs serve to help guide the tabs into clamping engagement with the respective truss during installation. While each of the tabs of the above-described embodiment has a flared lower portion, the reader will appreciate that the tabs (


32


,


42


,


62


,


72


,


112


,


122


) may be provided with no lower flared portions (

FIG. 13

) or just one of the tabs (


32


,


42


,


62


,


72


,


112


,


122


) of each pair (


50


,


80


,


130


) may be provided with a flared lower portion (FIG.


14


).




Another embodiment of the present invention is depicted in

FIGS. 15 and 16

. This embodiment is identical in construction to the spacer bar


20


above except that it only has the clamping tabs


50


and


80


for clamping two building components or trusses (


10


,


210


). The reader will appreciate that this embodiment of the present spacer bar is also installed in the above-described manner.




Yet another embodiment of the spacer bar of the present invention is depicted in

FIGS. 17-24

. This embodiment is essentially identical in construction to the spacer bar


20


as described above (and is designated as


20


′), except that the end tabs designated as


32


′ and


120


′ are formed by bending the entire end of the brace member


22


such that it is substantially perpendicular to the brace member


22


. Thus, as can be seen in

FIGS. 17-22

, the end tab


32


′ is bent substantially perpendicular to the planar lower surface


26


(i.e., angle A′ is approximately 90°) and end tab


120


is also bent substantially perpendicular to the lower surface


26


such that angle O′ is approximately 90°. End tab


32


′ may have an upper portion


34


′ and a flared or arcuate lower portion


36


′. Tab


32


′ may protrude from the lower planar surface a distance B′ which may be one inch long and the lower portion may be formed at a radius C′ of ¾ inch. Similarly, in this embodiment, end tab


120


′ has an upper portion


124


′ and a flared lower portion


126


. While in this embodiment, the end tabs (


32


′,


120


′) are formed from the ends of the brace member


22


, the person of ordinary skill in the art will appreciate that the end tabs may be formed by welding or otherwise attaching tabs to the brace member


22


. As can be seen in

FIGS. 17 and 24

, the spacer bar


20


is used and installed in the manners described above with respect to spacer bar


20


.




An alternative embodiment of the spacer bar (designated as


20


″) is depicted in

FIGS. 25-27

. As can be seen in those Figures, only one of the end tabs (i.e., tab


32


″) is formed from the end of the spacer bar


22


. The other end of the spacer bar


20


″ is formed in the manner described above. The remaining portion of the spacer bar


20


″ is essentially identical to corresponding portions of spacer bar


20


. Thus, the end tab


32


″ may be clamped onto a last truss as shown in FIG.


27


. The spacer bars depicted in

FIGS. 17-27

are constructed to accommodate three building components such as upper truss chords. However, the person of ordinary skill in the art will appreciate that the spacer bars may be constructed to accommodate various numbers of building components. For example,

FIG. 28

illustrates another embodiment of the spacer bar of the present invention designated as


420


that is constructed like the spacer bar depicted in

FIGS. 18-23

, except that it is adapted to accommodate two building components. In particular, the end tabs (


32


′,


72


′) are formed in the opposite ends of the end of the spacer bar


420


.




Yet another embodiment of the present invention is depicted in

FIGS. 29-39

. In this embodiment, the spacer bar


520


includes an elongated planar brace member


522


that has a planar upper surface


524


and a planar lower surface


526


. See

FIGS. 33 and 34

. Brace member


522


may be fabricated from metal such as cold rolled steel, hot rolled steel, stainless steel and aluminum. However, other materials such as wood, plastic, etc. could be successfully used. As can also be seen in

FIGS. 29-34

, the elongated planar brace member


522


has a first end


528


and a second end


529


.




In this embodiment, a first portion


530


adjacent the first end


528


is punched through the elongated planar brace member


522


to form a first tab


532


. Those of ordinary skill in the art will appreciate such punching operation may be performed by utilizing conventional metal punching techniques and apparatuses. Although in this embodiment, tab


532


is integrally formed with the elongated planar brace member


522


, the reader will appreciate that the tab


532


may be provided in different shapes and comprise a separate piece of material welded or otherwise affixed to the planar lower surface


526


. To facilitate attachment of the tab


532


to the truss, the tab


532


may be provided with one or more fastener holes


533


therethrough for receiving an appropriate fastener (i.e., screws, nails, etc.). See FIG.


34


. As can be seen in

FIG. 30

, the first tab


532


is bent downward from the planar lower surface


526


such that it extends substantially perpendicular thereto. First tab


532


may be one inch long. As can also be seen in

FIGS. 36 and 36A

, the first tab


532


has an upper portion


534


and a flared or arcuate lower portion


536


. As used herein the term “flared” encompasses any curved or flared portion that is not co-planar with the upper portion


534


of the tab


532


. Tab


532


may be manufactured as described above with respect to tab


32


.




The subject spacer bar


520


also includes a second portion


540


that is punched from the elongated planar brace member


522


to form a second tab


542


that is spaced a first “fixed” predetermined distance “D″” from the first tab


532


. The second tab


542


is also bent at an angle that is substantially 90° to the planar lower surface


526


of the brace member


522


and may be one inch long. The second tab


542


has an upper portion


544


and a flared lower portion


546


and may be constructed in the manner described above with respect to tab


542


. To facilitate attachment of the second tab


542


to the truss, one or more fastener holes


543


are provided through the tab


542


for receiving an appropriate fastener therethrough. See FIG.


36


. As can be seen in

FIGS. 36 and 36A

, a first planar portion


547


of the planar brace member


522


extends between the first tab


532


and the second tab


542


. One or more fastener openings


548


may be provided through the first planar portion


547


to enable conventional first fasteners


49


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


520


to the truss


10


as will be described in further detail below.




Tabs (


532


,


542


) form a first pair of integral clamping tabs collectively designated as


550


. In one embodiment, the first predetermined distance “D″” is slightly greater than or equal to the cross-sectional thickness “F” of the upper chord


14


of the truss


10


to be clamped thereby (i.e., “D″” could range from 0-{fraction (1/16)} inches greater than distance “F”).




Also in this embodiment, a third portion


560


is punched through the elongated planar brace member


522


to form a third rectangular shaped tab


562


that is spaced from the second tab


542


a second “fixed” predetermined distance “G″”. See FIG.


33


. In this embodiment, distance “G″” may be, for example, 22½ inches. Third tab


562


is bent downwardly from the planar lower surface


526


such that it is substantially perpendicular thereto. The third tab


562


may be formed in the same manner as tab


62


and has an upper portion


564


and a flared lower portion


566


as described above and may have one or more fastener holes


63


therethrough. See

FIGS. 37 and 37A

.




A fourth portion


570


is punched from the elongated planar brace member


522


to form a fourth rectangular shaped tab


572


that protrudes substantially perpendicular from the planar lower surface


526


and is spaced from the third tab


562


a third predetermined distance “K″”. The fourth tab


572


is formed in the same manner as the second tab


542


and has an upper portion


574


and a flared lower portion


576


and may have one or more fastener holes


573


therethrough. See FIG.


37


.




Tabs (


562


,


572


) form a second pair of integral clamping tabs collectively designated as


580


. In one embodiment, the third predetermined distance “K″” is equal to or slightly greater than the cross-sectional thickness “L” of the upper chord


214


of the second truss


210


to be clamped thereby (i.e., distance “K″” may be from 0-{fraction (1/16)} inches greater than distance “L”).




As can be seen in

FIGS. 37 and 37A

, a second planar portion


582


of the planar brace member


522


extends between the tabs (


562


,


572


). One or more second fastener openings


584


may be provided through the second planar portion


582


to enable conventional second fasteners


586


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


520


to the upper chord


214


of a second truss


210


in the manner described above.




A fifth portion


610


is punched from the elongated planar brace member


522


to form a fifth rectangular shaped tab


612


that is spaced from the fourth tab


572


a fourth fixed predetermined distance “M”. Fifth tab


612


is bent downwardly from the planar lower surface


526


such that it is substantially perpendicular thereto and may be constructed in the same manner as tab


112


as described above. See

FIGS. 38 and 38A

. The fifth tab


612


is formed in the same manner as the first tab


532


and has an upper portion


614


and a flared lower portion


616


and may have one or more fastener holes


613


therethrough.




A sixth portion


620


is punched from the elongated planar brace member


522


to form a sixth rectangular shaped tab


622


that protrudes substantially perpendicular from the planar lower surface


626


and is spaced from the fifth tab


612


a fifth predetermined distance ““P””. See FIG.


38


. The sixth tab


622


is formed in the same manner as the second tab


542


and has an upper portion


624


and a flared lower portion


626


and one or more fastener holes


623


therethrough.




Tabs (


612


,


622


) form a third pair of integral clamping tabs collectively designated as


630


. In one embodiment, the fifth predetermined distance “P” is equal to or greater than the cross-sectional thickness “Q” of the upper chord


314


of a third roof truss


310


(i.e., distance “P” may be 0-{fraction (1/16)} inch greater than distance “Q”).




As can be seen in

FIG. 38

, a third planar portion


632


of the planar brace member


522


extends between the tabs (


612


,


622


). One or more third fastener openings


634


may be provided through the third planar portion


632


to enable conventional third fasteners


636


(i.e., nails, screws, etc.) to be inserted therethrough to fasten the spacer bar


520


to a building component such as roof truss


310


in the manners discussed above.




The reader will further appreciate that the tabs (


532


,


542


,


562


,


572


,


612


,


622


) are substantially rigid with respect to the planar brace member


522


. However, if the spacer bar


520


is fabricated from the above-identified material, such material enables the tabs to flex slightly when the truss component is inserted therebetween. For example, during installation, the tabs (


532


,


542


) may each flex outward in the manner described above. Thus, the term “rigid” as used herein with respect to tabs (


532


,


542


,


562


,


572


,


612


,


622


), means that such tabs cannot be repositioned longitudinally along the brace member


522


but rather remain affixed thereto while permitting their respective lower portions to flex slightly for installation purposes. That term also encompasses tabs that do not flex and are unable to be repositioned longitudinally along the brace member


522


.




To provide the spacer bar


520


with axial rigidity between in the first pair of clamping tabs


550


and the second pair of clamping tabs


580


, a first reinforcing member


590


may be centrally disposed in a portion


525


of the elongated planar brace member


522


that extends between the second tab


542


and the third tab


562


. In this embodiment, the first reinforcing ember


590


comprises a first reinforcing rib segment


592


that is integrally formed in the portion


525


and is essentially identical to reinforcing rib segment


92


as described above. More particularly and with reference to

FIGS. 31 and 32

, the first reinforcing rib segment


592


may comprise an arcuate rib that is centrally disposed in the portion


525


. For example, in an embodiment wherein distance G″ is 22½ inches, the first reinforcing rib segment


92


may be


21


inches long. In an embodiment wherein the elongated planar brace member


522


is 3.5 inches wide, the first reinforcing rib segment


592


may be 1.5 inches wide and be ¾ inches deep. The rib segment


592


may be formed with radiused edges with respect to the planar upper surface


524


of the brace member


522


. Those of ordinary skill in the art will appreciate, however, that other shapes and sizes of reinforcing members may be formed in or attached to the planar brace member


522


to provided additional rigidity thereto without departing from the spirit and scope of the present invention.

640


comprises a second reinforcing rib segment


644


that is integrally formed in the portion


642


and is sized similarly to the reinforcing rib


144


as described above. Those of ordinary skill in the art will appreciate, however, that other shapes and sizes of reinforcing members may be formed in or attached to the planar brace member


522


to provide additional rigidity thereto without departing from the spirit and scope of the present invention.

. In one embodiment, the angled or clipped portions are at approximately


450


with respect to the lower surface


526


of the brace member


522


(Angle “Z” in FIG.

Thus, from the foregoing discussion, it is apparent that the present invention solves many of the problems encountered by prior truss spacer devices. In particular, the spacer bars of the present invention are relatively easy to manufacture and install. Because of their clamping action, they rigidly retain the trusses or other building components in a desired upright and spaced-apart relationship while additional trusses and fasteners are installed. It is believe that additional trusses may be installed in the above-described manner prior to affixing the spacer bars to the trusses with fasteners such as nails, screws, etc. without the risk of the trusses toppling over. In addition, the present spacer bars do not have to be removed from the trusses before installing appropriate decking materials to the trusses. Those of ordinary skill in the art will, of course, appreciate that various changes in the details, materials and arrangement of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by the skilled artisan within the principle and scope of the invention as expressed in the appended claims.
