Masonry Wall Intersections
**************************************************************************
NOTE: Details will be shown on the drawings which
illustrate corners and intersections of structural
bond beam reinforcement and factory-formed joint
reinforcement. When joint reinforcement is not
used, delete prefabricated corners or tee pieces.
**************************************************************************
Each course shall be masonry bonded at corners and elsewhere as shown.
Masonry walls shall be anchored or tied together at corners and
intersections with bond beam reinforcement and prefabricated corner or tee

Partitions
**************************************************************************
NOTE: Walls and partitions which serve as fire
walls or fire-rated walls will be shown. Sections
and details of these walls will clearly indicate the
extent of such walls. Non-structural masonry
partition walls will not be tied in any way to
structural or exterior masonry walls. Isolation
joints will be used at these intersections. When
100 mm (4 inch) masonry partitions are not used,
delete reference to these units and their
intersections.
**************************************************************************
Partitions shall be continuous from floor to underside of floor or roof
deck where shown. Openings in firewalls around joists or other structural

the ceiling level. An isolation joint shall be placed in the intersection
