Both gang form bolts and wedge bolts are used to connect panels
and gang form ties. Gang bolts connect panel siderails and secure the
longer ends of gang form ties. The longer end on a gang form tie
allows the tie to break back and permits stripping of the gang without
disassembly. Like wedge bolts, gang form bolts make separating
adjoining gang sections easy.
Figure 9-43 shows a gang form assembly. Panels may be stacked,
one above another, to form tall walls. Stacked panels mate tightly to
minimize form joints. Lift brackets are used as attachment points for
rigging and safe handling of large gangs. For some applications,
walers and strongbacks are used only for alignment. However, some
applications use high-capacity ties with walers and strongbacks to
gather the load of the panels. Therefore, the load is actually placed on
the ties through the walers and strongbacks. Because of the strength
and rigidity of the system, ties may be placed farther apart than they
would normally be in conventional gang forming. Recommendations
of manufacturers should be followed for safe assembly and application
of modular panels for gang forms.
