Abstract:
This invention will assist or allow an operator to easily lift a concrete frame panel into position without much risk of personal injury and with greater efficiency of time. A lifting bar is secured to a vertical frame member through openings in the vertical frame members and a crane or forklift is used to lift the panel prior to setting it to form the wall.

Description:
BACKGROUND OF THE INVENTION 
     A. Field of the Invention 
     This relates to the construction trade in general and specifically a device to assist in erecting frame members to construct a wall. 
     B. Prior Art 
     There are many other prior art references to framing devices. Representative examples of this type of structure, including making a cast panel that can be found at Manning, U.S. Pat. No. 5,976,442, and Parker, U.S. Pat. No. 6,625,937. Both the Manning and Parker are modular building methods of construction. 
     This device is used specifically with frame members to build a wall. Frame members are erected into a rectangular configuration and concrete is poured into the middle of the frame members to form the wall. This application addresses both the safety concerns to the workers when a wall is erected as well as achieving a significant cost savings because of the reduction in manpower that is required. None of the prior art achieves these results. 
     BRIEF SUMMARY OF THE INVENTION 
     This device will be used in the field of construction. particularly, commercial construction. It is often necessary to make or “form” concrete walls by erecting two similarly situated panels that are spaced a predetermined distance apart and closed at the respective ends. Concrete is then poured into the cavity and allowed to set or cure to form the wall. The panels are then removed for the formation of the next wall section. 
     The panels, however, are very heavy and are quite awkward and often dangerous to lift. Most of the panels are standard sizes and different-sized panels can be placed together to form different-sized walls. The panels are further comprised of a plurality of vertical frame members and horizontal frame members of a certain predetermined thickness. Openings are provided on the vertical frame members and enable the device to be lifted by a crane or forklift. 
     One side of the panel will be open to expose the vertical frame members and the other side is solid. 
     One of the difficulties or challenges arises when erecting the frame members to initially form the wall structure. A greater challenge is posed when the frame members must be stacked on top of each other which is sometimes required to erect a higher wall. When a higher wall is to be erected, the frame members must be stacked one frame member on top of the other. 
     Each frame member has various horizontal and vertical members with an opening on the vertical as well as the horizontal members. These openings allow a lifting mechanism with a piece of channel to be placed inside the opening and secured with a pin or spike. This enables a crane to lift the entire panel to form the wall. The device can then simply be dismantled after use. 
     This device eliminates the risks of endangering humans when lifting these panels and reduces the amount of manpower that is required to lift and position the panels. 
     The device will be comprised of a lifting bar on which will be placed two members that slide along the length of the tube or bar. Stop mechanisms will be placed on either end of the bar or tube to prevent the sliding pieces from inadvertently slipping off the bar. 
     On the bottom of the sliding member will be a piece of channel in the general shape of an “L.” The “L” member will have an opening in the middle, and the opening in the “L” is placed through the opening of the vertical frame members. Once the lifting bar is secured to the panel a forklift or crane is attached to the lifting bar. 
     The panels are lifted safely by the crane or forklift. Although some human intervention is necessary, the amount required is greatly reduced. This device results in cost savings, but will more importantly reduce the risk of human injury.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     It is important sometimes in erecting walls to place identical frame members or panels a predetermined distance apart in order to pour concrete to form a wall. The identical frame members essentially come in a rectangular shape although the shapes may come in different sizes and dimensions. The purpose of the panels  10  is to enable the worker to pour a large amount of concrete  1  in-between two identical frame members to form a wall such as depicted in  FIG. 8 . 
     The panels  10  that are used to form a wall are oftentimes very heavy and difficult to maneuver. The panels  10  will be comprised of a series of vertical frame members  20  as well as horizontal members  19 . Openings  15  are provided on the vertical frame members  20 . Because the panels are used in the construction trades, they are likely to be constructed from steel or other strong durable material. 
     The vertical and horizontal members form the essential structure of the panel  10 . Two horizontal frame members  19  of predetermined thickness, width and length will form the top and bottom sides of the panel  10 ; the other two sides will be formed by two vertical frame members  20 . When the horizontal frame members are secured to the vertical frame members in this fashion a rectangular shape is created such as depicted in  FIG. 1 . 
     Interior to the outer edges of the panel  10  are a plurality of vertical frame members  20  that are placed between the horizontal frame members and extend the entire length of the panel. Openings  15  are provided in the vertical frame members. 
     One side of the panel  10  is open to expose the vertical frame members  20  and the other side is closed or solid  21  to contain the concrete as it is poured such as depicted in  FIG. 8 . In the middle between the outer edges of the panel, a plurality of vertical members are interspaced between the bottom and top horizontal members to form the panel  10 . 
     When this device is used, a lifting bar  8  will be used to lift and position the panel  10 . The lifting bar  8  is also constructed from a strong metal and steel is probably a preferred choice. 
     On the lifting bar  8  will be two slide members  9  that will be allowed to move along the lifting bar. On a portion of the slide member  9  will be a piece of channel or “L” shaped member  11  with an opening  18  in the center of the “L” shaped member such as depicted in  FIGS. 5 and 6 . A lifting loop  14  is attached to the slide member  9 . 
     A portion of the “L” member  11  will be placed through the opening  15  of the vertical frame member  20  so that the opening  18  protrudes on the opposite side of the vertical frame member  20 . The L member is secured in place by putting a spike, pin, tapered pin, nail or other type of connection means  13  through the opening  18  in the L member  11 . 
     In order to insure that the sliding members  9  do not accidentally or inadvertently fall off the lifting bar  8 , a pair of stop mechanisms  12  will be provided near the ends of the lifting bar  8 . The stop mechanism  12  may be a raised protrusion or may be made as part of the lifting bar  8  but regardless extend a predetermined distance away from the outer surface to prevent the sliding mechanism  9  from falling off the lifting bar  8 . 
     When the lifting bar  8  is to be attached to the panel  10 , the panel  10  is positioned such that the worker can reach the exposed vertical frame members  20 . The panel may be laid flat or may be laid at an angle but regardless of the position the worker must be able to reach the exposed vertical frame members. 
     The lifting bar  8  is then placed on a portion of the exposed panel and the sliding mechanisms  9  are positioned so that the L shaped member  11  is aligned with a predetermined opening on the vertical frame member  20 . The L shaped member  11  is then slid through the opening in the vertical frame member  15  so that a portion of the L shaped member opening  18  protrudes from the other side of the vertical frame member. 
     The means to secure  13  the L shaped member is then placed through the opening  18 . The means to lift the lifting bar  7  is then attached to the lifting loop  14  on the sliding mechanism  9  such as depicted in  FIG. 6 . 
     Once the lifting bar  8  is secured to the vertical frame member  20  of the panel, the lifting bar  8  is secured to the lifting device which may be a crane or forklift such as depicted in  FIG. 2 . Chains, ropes or cables  7  may be used to secure the lifting bar to the lifting device by attaching one end of the chain, rope or cable to the lifting loop  14  on the lifting bar. A second bar  6  may also be used by the lifting device to lift the panel.
