of wall 10 with respect to frame 14 apparatus 16 also allows for in plane movement of wall 10 with respect to frame 14 turning now to fig2 there is shown apparatus 16 for use in conjunction with vertical post tensioning bar 18 apparatus 16 generally includes a brace 22 and a face 24 brace 22 can include at least one and preferably two adjustment slots 26 adjustment slots 26 receive suitable attachment means such as expansion anchors powder driven anchors or bolts or some other fastener not shown for attaching brace 22 to frame 14 an alternative method is to field weld brace 22 to a steel frame slots 26 preferably are parallel to each other to provide additional adjustment in the plane of the wall face 24 includes at least one and preferably two flanges 28 extending outwardly from face 24 to define a bar receiving area 30 flanges 28 limit movement of bar 18 in a direction perpendicular to wall 10 flanges 28 preferably are formed from face 24 and each flange 28 has a first end 32 connected to face 24 and a second end 34 independent of the other flange 28 alternatively flanges 28 can be part of a separate u shaped channel that is attached to a solid face 24 by welding for extra strength flanges 28 preferably extend substantially parallel to one another as shown in fig2 however other configurations of flanges 28 can be used if desired for example flanges 28 can diverge from one another e g to form.
