(19) The elongated support pipe 46 has a pipe body 58 that defines a first or lower end 60 and a second or upper end 62 of the support pipe 46 and an elongated pipe axis 64 through the support pipe 46 (i.e., between the first/lower end 60 to the second/upper end 62), as best shown in
(20) To allow the user to secure the support pipe 46 at its desired height, the apparatus 10 has a pipe length securing mechanism 70 that is cooperatively configured with the pipe members 66/68 and is structured and arranged to secure the relative position of the pipe members 66/68 to each other so as to fix the length of the support pipe 46 (i.e., height of the apparatus 10). In the embodiment shown in the figures, securing mechanism 70 has one or more clamping devices 72 (two are shown) that each comprise a clamping member 74 that is tightly engaged by a U-shaped bolt 76 and cooperatively configured connecting members 78 (such as a nut or the like) in a manner such that when the clamping member 74 is clamped against the pipe body 58 by the U-shape bolt 76 and connecting members 78, the two pipe members 66/68 will be engaged with each other to prevent upward and downward movement of the pipe members 66/68 relative to each other. As will be readily understood by persons who are skilled in the art, a wide variety of different types of and configurations of securing mechanism 70 can be utilized with the new apparatus 10. For instance, the securing mechanism 70 of apparatus 10 can be of the type that is not a clamping device 72 or is a clamping device 72 that does not utilize a clamping member 72, U-shaped bolt 74 and connecting members 76. The securing mechanism 70 can be of the type that comprises a removable pin and a plurality of apertures, a retractable pin that extends through an aperture, threads which allow one pipe member 66/68 to move relative to the other pipe member 66/68, friction engagement between the two pipe members 66/68, a set screw or other connector through the outer pipe member 66/68 to engage the outer surface of the inner pipe member 66/68, a variety of internally disposed devices that can be utilized as the length adjusting mechanism 70, or the like.
(21) For purposes of describing the present invention, for purposes of describing the use and relative location of the various components of the present invention, the terms upper, upward, upwardly, upper and top and the like and the terms lower, downward, downwardly and bottom and the like refer to the direction, respectively, of the first/lower end 60 and second/upper end 62 of the support pipe 46 when the apparatus 10 is in its normal upright position 69 when in use to engage one or more horizontally disposed wind girts 24 of the frame 14 of building 16, as shown in
(22) The base assembly 48 is structured and arranged to support the new apparatus 10 on a support surface 56 when the apparatus 10 is in use to level and support at least one wind girt 24. In the preferred embodiment, the base assembly 48 is utilized with the lever assembly 50 and support pipe 46 to provide a fixed component against which the lever assembly 50 operates to move the support pipe 46 upward or downward, relative to the base assembly 48 and support surface 56, to allow the girt support assemblies 52 to engage and support the wind girts 24, as shown in
(23) In the embodiment of the apparatus 10 shown in the figures, the base assembly 48 also comprises one or more curved shaft members, shown as first curved shaft member 82 and second curved shaft member 84 in
(24) As set forth above, the lever assembly 50 is structured and arranged to allow the user to raise the support pipe 46, and therefore the one or more girt support assemblies 52 attached thereto, when he or she desires to engage one or more wind girts 24 and move the wind girts 24 from their sagging condition 32 to the level condition 34, as shown with regard to
(25) The lever assembly 50 shown in the figures has an upper section 96 comprising one or more upper lever members 98, such as the two shown
(26) With the appropriate number and placement of girt support assemblies 52 on the support pipe 46, as set forth below, the user places the apparatus 10 in position below the wind girts 24, which will be in their sagging condition 32, of the frame 14 of a building 16, such as shown in
(27) In a preferred configuration of the new apparatus 10, each girt support assembly 52 is structured and arranged to securely, but moveably, attach to the pipe body 58 of the support pipe 46 and to engage a wind girt 24 so as to move upward with the support pipe 46 as it moves upward by the user moving the lever assembly 50 to its extended position 92 and move the wind girt 24 from its sagging condition 32 to its level condition 34, as shown in
(28) In the embodiment shown in the figures, each girt support assembly 52 is moveably attached to the support pipe 46 and configured to allow the user to tightly secure the girt support assembly 52 in the desired girt supporting position, which is the position where the girt support assembly 52 needs to be located so it will engagedly abut against and support the wind girt 24 when the lever assembly 50 is in its extended position. The girt support assemblies 52 shown in the figures comprise a bracket 112 that is sized and configured to extend outwardly from the support pipe 46, a pipe attachment mechanism 114 which is attached to or integral with the bracket 112 to securely, but moveably, attach the bracket 112 to support pipe 46 and a girt contact plate 116 that is attached to or integral with the bracket 112 and sized and configured to engagedly contact and support a wind girt 24, as best shown in
(29) In the embodiment shown in the figures, pipe attachment mechanism 114 is structured and arranged to moveably engage, but subject to being tightly engaged with, the support pipe 46. In one configuration, the pipe attachment mechanism 114 has an engaging bracket 118 and a cooperatively configured engaging member 120. The engaging bracket 118 is sized and configured to be placed in close abutting relation with the pipe body 58 of the support pipe 46 and the engaging member 120 is sized and configured to extend around the support pipe 46 and be engaged with the engaging bracket 118 to pull the engaging bracket 118 tightly against the pipe body 58 to secure a girt support assembly 52 in place on the support pipe 46, as best shown in
(30) As will be readily appreciated by persons who are skilled in the art, a wide variety of other components and different configurations of such components can be used for the girt support assemblies 52 other than those described above. For instance, the pipe attachment mechanism 114 can be modified as may be necessary or beneficial to connect to support pipes 46 other than a cylindrical pipe body 58, such as a support pipe 46 having a pipe body 58 that has a square, rectangle or oval cross-section. In addition, the pipe attachment mechanism 114 can be configured to engage the support pipe 46 in significantly different manners other than having an engaging bracket 118 pressed against the pipe body 58 thereof. For instance, pipe body 58 can have a plurality of apertures therein or therethrough that a bolt, screw or other connector is passed into or through to secure the bracket 112 to the support pipe 46. Likewise, the pipe attachment mechanism 114 can comprise a pair of engaging brackets 118 that are attached to each other to hold the bracket 112 in place on support pipe 46. As set forth above, in embodiments where changing the location of the girt support assemblies 52 will not be necessary (such as always having the same spacing between the wind girts 24), the bracket 112 can be fixedly attached to or integral with the pipe body 58 of the support pipe 46.
(31) The support chain 54 is utilized to secure the apparatus 10 to one or more frame members of the frame 14 to prevent the apparatus 10 from becoming dislodged and falling free, which could injure persons below, and to connect to a crane or other aerial lifting machine for moving the apparatus 10. As best shown in
(32) As set forth in the Background, when the wind girt 24 is in a sagging condition 32, which is due to the natural sag of supporting its own weight, the user will have difficulty attaching the components of the wall 22, such as panels 18, panelized section 20 and the like, to the frame 14 of building 16 in a manner which is effective, efficient and aesthetically pleasing. The apparatus 10 is structured and arranged to raise and level the wind girts 24 without the potential problems of the prior art use of dunnage 30 and the like, such as shown in
(33) A method 12 of utilizing the new apparatus 10, generally comprises the steps of: (1) utilizing the length adjusting mechanism 70 to extend the support pole 46 to have sufficient height to extend upward above the uppermost wind girt 24 and installing a girt support assembly 52 for each wind girt 24 to the pipe body 58 of the support pipe; (2) positioning each girt support assembly 52 on the support pipe 46 so a girt support assembly 52 will be below each wind girt 24; (3) operating the pipe attachment mechanism 114 of girt support assembly 52 to tightly secure each girt support assembly 52 to the support pipe 46; (4) standing the apparatus 10 in its upright position 69 at a span 26 between the posts 28 of the frame 14 of a building 16 with the footplate 80 thereof on the support surface 56, the girt contact plate 116 of each girt support assembly 52 positioned below a wind girt 24 that is in its sagging condition 32 and the lever assembly 48 in its retracted position 90; and (5) moving the lever assembly 50 to its extended position 92 to raise the support pipe 46 and the girt support assemblies 52 upward to engage each wind girt and move each wind girt 24, in one operation, to their level condition 34. If desired, the user can secure the free end of the safety chain 54 to other components of the frame 14 to prevent the apparatus 10 from falling during use thereof. Once each of the wind girts 24 are in their level condition 34, the user can install the panels 18, panelized sections 20 and/or other wall components to the frame 14 to form the walls 22 of the building 16. Once the wall components are installed, the user moves the lever assembly 50 back to its retracted position 90 and moves the apparatus 10 away from the frame 14, such as to a new location in another span 26 of the frame 14. If desired, the user can attach the free end of the safety chain to a crane or other aerial lifting machine to quickly and easily move the apparatus 10 to its next location.
(34) The components of the new apparatus 10, including the support pipe 46, base assembly 48, lever assembly 50 and the girt support assemblies 52 can be made out of wide variety of materials that are sufficiently strong and rigid to support the support pipe 46 in a stiff upright position with the footplate 80 pressed against the support surface 56 and the girt support assemblies 52 pressed against the wind girts 24 in order to move the wind girts 24 from their sagging condition 32 to their level condition 34. The safety chain 54, which is preferably flexible, should be sufficiently strong to prevent the apparatus 10 from falling and to allow the user to move the apparatus 10 with a crane or other aerial lifting machine. Preferably, the material selected for these components will also be sufficiently corrosion resistant so that it will not corrode when utilized and stored outside. As will be readily appreciated by persons who are skilled in the art, various metals, plastics, composites and the like can be utilized for different or all of the components of the apparatus 10. In one embodiment, the primary material is steel that is selected, treated or coated to reduce the likelihood of corrosion issues.
