footing as sole plates. The top edge of the plywood facing
extends ¹⁄8 in. above the top of each plate. Toe-nail the plates
to the nailer inserts in the footing.
2. Place through-wall button-end spreader ties at the desired
spacing across the sole plates. Either hit each tie with a hammer
to embed it in the projecting edge of the plywood or precut
notches in the edge of the plywood to receive the ties.
3. Set the lower tier of form panels on the sole plates extending
along the footing, with the ends of the panels butting against
each other. Fasten the end studs of adjacent panels together,
using bolts, short form ties, or double-headed nails. Then nail
the lower plate of each form panel to the 4- by 4-in. sill plate,
and wedge-clamp the form ties.
4. Space form ties along the top surface of the tier panels.
5. Set another tier of form panels on top of the lower tier. Fasten
the ends of the panels together, as described previously, and
then nail the bottom plate of the second tier to the top plate of
the first tier. Then wedge-clamp the second row of form ties.
6. Install form spacers across the top tier of forms, using 1 × 4
wood boards, metal straps, U-shaped steel rods set through
prebored holes in the top plate, or some other suitable method.
The U-shaped rods can be inserted and removed quickly and
should have a very long life.
7. Install vertical double 2 × 4 wood strongbacks along the inside
wall, at 8-ft spacings at the end junctures of panels, using
through-wall form ties to hold them in place.
