E-BEAM and SUPER STUD. These construction support products
are used in conjunction with contractor-supplied plywood to produce
a lightweight modular wall-forming system. This system weighs
approximately 12 lb per sq ft, including pipe braces and scaffold
brackets. E-BEAMs bolt directly to the SUPER STUD vertical stiffbacks
through predrilled holes on 2-in. centers that line up with the
SUPER STUD hole pattern. Thus, the forms may be assembled with
little hardware or clamping devices in minimal time.
Plywood may be attached to the E-BEAM with a standard air
nailing gun, or case-hardened nails can be driven by hand through
the plywood and into the E-BEAM. The withdrawal strength is virtually
the same as for nails driven with an actuated gun. Self-drilling
and tapping screws driven by a drywall screw gun also provide a
satisfactory fastening device.
A large variety of accessories is available for bracing and adjustments
of the SUPER STUD system. Two cross-sectional dimensions,
6 by 6 in. and 9 by 9 in., are available in four standard modular
lengths, which vary from 2 to 12 ft. The SUPER STUD system with
accessories offers the versatility of a giant erector set (Figure 9-45).
