1. CONCRETE
FLOOR
ASSEMBLY:
Three-hour
rated
concrete
floor
assembly made from either lightweight
or normal weight concrete with a density
of 100-150 pcf, with a min. thickness of
4 in. at the joint face. Overall slab
thickness may vary to accommodate
various blockout depths (longitudinal
recesses) formed in the concrete, to
house the architectural cover plate. The
blockout width may also vary without
restriction.
2. CURTAIN
WALL
ASSEMBLY:
The
curtain wall assembly shall incorporate
the following construction features:
A. Mounting Attachment: (Not shown)
Attachment of the curtain wall
framing to the structural framing
shall be according to the curtain wall
manufacturer's instructions to allow
vertical shear movement only. When
required, the mounting attachments
to the floor slab shall be connected
to the joint face of the floor slab,
according
to
the
curtain
wall
manufacturer's instructions. Max.
distance
between
mounting
attachments shall be 10 ft. One
optional method is to use min. 8 in.
wide by 3/4 in. thick extruded
aluminum Halfen mullion mounting
brackets with one nom. 2 in. high
leg for support and attachment to
the mullion and with one leg at least
6 in. longer than nominal joint width.
Attach the mounting bracket to the
top of the floor with two min 1/2 in.
dia.
steel
masonry
anchors
in
conjunction
with
washer
plates
supplied with the mounting brackets.
B. Aluminum Framing: Install I shaped
mullions
and
transoms,
sized
according to the curtain wall system
manufacturer's
guidelines.
Min.
overall
dimensions
of
mullion
framing is 0.125 in. thick with a min.
5-1/2 in. height and a min. of 2-1/2
in. width of the extrusion. Min.
overall
dimensions
of
transom
framing is 0.125 in. thick with a min.
2 in. height and a min. of 2 in. width
of the extrusion. Mullions are to be
spaced a min. 56-1/2 in. on center
(oc) and transoms are to be spaced
a min. 31 in. oc For the spandrel
region, the lower transom must be
placed a min. of 21 in. below the
concrete floor (as measured from
the underside of the floor to the top
side of the transom) and the upper
transom must be placed a min. of 3
in. above the floor (as measured
from the top surface of the floor to
the underside of the transom) while
maintaining the min. 33-1/2 in.
spandrel
height.
One
optional
fastening method is to space the
mullions as noted herein and secure
the mullion mounting anchors (Item
2A) at each floor level in conjunction
with extruded aluminum clips bolted
to the sides of the mullions and
designed to engage the vertical leg
of the Halfen mullion mounting
bracket in conjunction with an
extruded
aluminum hook/leveling
connector.
C. Vision Glass Panels: Glass panels
shall be sized and attached to
curtain wall framing according to the
curtain wall system manufacturer's
guidelines. Use a min. 1/4 in. thick,
clear heat-strengthened (HS) glass
or tempered glass with a max. width
and height less than the aluminum
framing oc spacing, which allows
the glass to be secured between the
notched shoulder of the aluminum
framing and pressure bar. Panels
are secured with a thermal break
(rubber extrusion), pressure bar
(aluminum extrusion), min. 1/4-20 x
5/8 in. long screws, and a snap face
(aluminum extrusion).
D. Glass
Spandrel
Panels:
Glass
panels shall be sized and installed
to curtain wall framing according to
