“A-A” Section Above Splice
V: Vertical Splice Applications
Vertical Splice Joints at SSG Verticals and Captured Horizontals
A.) Splice should occur at the spandrel areas.
B.) Fabrication Note: Match drill the splice for shear block attachment.
C.) Splice Note: The vertical
mullions that are structurally
glazed must be spliced at the
horizontal locations. (All mullion
splice locations must be
reviewed by a factory
engineer.)
D.) Where the head clearance is
insufficient to allow the top
mullions to be lifted over the
splice, a retractable splice will
be used. The splice is taped
into the top mullion and
dropped to a stop screw in the
mullion below. Don’t match
drill the anchors until a check of
the expansion joints and wall
installation is made.
Note: All anchors must be fixed
before glazing begins.
Note: When the mullion splice is
shop installed into the lower
mullion, (2) fasteners will be
used in the standard locations
as shown.
Note: SSG Vertical Splice Locations EFCO
recommends that Vertical Splice Line should
be below the Intermediate Horizontal
Member. This will Minimize Shear Stress at
the Structural Seal Line.
