After about 15 panels (3 sets) are in place, measure
the building length at both ends (just above forms) and
at the center of the arch. This measurement will seldom
be exactly one foot per panel (usually slightly more),
but should be equal for each panel. Adjust the ends to
equal the center measure. Panels are flexible enough to
adjust slightly. Check these measurements periodically
during building construction. Since exact building
lengths are difficult to predict, the end wall attaching
angle on the finishing end of building should not be put
in place until all panels are set.
After arches are in place, set the longest end-wall
panel in the form, plumb, and clamp it in place. Work
from the longest panel outward and be careful to
maintain plumb.
CONSTRUCTION DETAILS
The K-span building system is similar to other types
of preengineered or prefabricated buildings in that
windows, doors, and roll-up doors can be installed only
when erection is completed. When insulation of the
building is required, insulation boards (usually 4 by 8
feet) may be of any semirigid material that can be bent
to match the radius of the building. The insulation is
installed using clips, as shown in figure 9-37.
When the integrity of the end-wall panels is
continuous from ground to roof line, the end walls
become self-supporting. The installation of windows
(fig. 9-38), and aluminum and wood doors (figs. 9-39
and 9-40, respectively), presents no problem since the
integrity of the of the wall system is not interrupted.
