90° Corners
For wall thicknesses >18" but
≤24", in addition to extra locks
steel rails must also be mounted
at all tie elevations except the
top two, with at least one flange
screw each, and bolted together
at the corner with a flange screw
18 and flange nut 100 (Fig.16.1).
There must be at least one panel
(1' or wider) adjacent to the corner
panels and inside corner.
Flange screws securing rails to
panels shall be tightened by
turning with a hammer claw or
bar until snug, followed by a few
hammer blows (minimum 110
ft-lbs torque).
An example corner elevation for
walls >18" but ≤24" thick is
shown in Fig.16.2.
Outside Corners Without
Reinforcing Rails
When it is not possible or practical
to install corner rail reinforcing
for walls over 18" thick, the
lock configuration shown in
Fig.16.1 can be used at a reduced
maximum allowable concrete
pressure of 1100 psf.
