Removal of mast ties
WARNING
It is
mandatory
to make sure that
all tension (or compression) is released
from
the mast tie before attempting to unpin it from the wall tie.
Before attaching masts to the building using the mast tie system, anchor fasteners or any
other attachment used to attach wall tie brackets must be installed on a solid part of the
building structure able to sustain the loads to be imposed. Concrete slabs, columns, steel
beams, relief angles and other structural elements can be used provided they can sustain
the tension / compression and shear force of the anchoring installation, as described below.
It is recommended to refer to the site engineer to validate the capacity of the structure on
which the anchoring system will be installed.

Each anchor fastener shown in fi g. 6.27
must be able to sustain appropriate
tension / compression and shear force for
the application. Refer to p. 92 of this
section for more information. A minimum of
six anchor fasteners is required.
