Prefabricated Wood Form Panels
Prefabricated wood panels of the types illustrated in Figure 9-18 have
several advantages when compared with wall forms built in place.
They can be assembled quite rapidly once a pattern is fabricated for
each part. They can be erected and removed quickly. If they are constructed
solidly, they can be used many times.
They are erected side by side to produce a wall form of any
desired length. Filler panels less than 2 ft wide will enable them to be
used for walls whose lengths are not multiples of 2 ft. Adjacent panels
should be bolted or nailed together while they are in use. Forms
on opposite sides of a wall are held in position with form ties, placed
in the indicated notches in the frames as the panels are erected. Two
rows of horizontal wales, one along the bottom form ties and one
along the top form ties, should be used to ensure good alignment.
Figure 9-18 shows a top view of an inside corner panel whose
dimensions can be selected to fit any wall thickness. Figure 9-19 illustrates
a method of connecting outside panels together at a corner. Steel
corner clips are used to secure the corners of the panel system.
The studs must be nailed securely to the 2 × 4 frame members with
20d nails. A metal connector, of the size and type illustrated, should be
installed at each end of each stud and nailed to the stud and frame. One
