Bulkheads
Rails, Column Clamps, & Ties
Rails are secured to the panels
using column clamps and flange
nuts (Fig.34.1). For steel rails up
to 8' long the allowable bending
moment is 7.62kip-ft, and
Ix = 5.3 in.
The column clamp's safe working
load in tension is 4750lb on
MevaLite panels. Column clamps
must be installed so that they
straddle the panel cross members.
The ends of the vertical bulkhead
panels are tied by installing taper
ties or threadbars using tie claws
so that the ties clear the bulkhead
(Fig.34.2).
Caution:
Never use taper ties or threadbars
as a means of supporting
bulkheads where shear loads
would be applied.
Ties with tie claws are not required
on horizontal panels since they are
tied internally.
Steel rails and ties are to be
installed as shown in Figure34.3.
