Steel Floor Deck Introduction
Wheeling
Super-Bond® Composite Floor Deck is produced for use in low-rise,
high-rise and manufacturing sectors of the nonresidential market.
The
unique engineering behind Wheeling Super-Bond deck serves an important
and cost efficient dual purpose: the system acts as a working platform
before and during concrete placement, eliminating the costly work
normally needed to construct and remove wood forms. Also, it acts
as a positive reinforcement for the concrete slabs: rebar in the
concrete is seldom needed. In most projects the Super-Bond principally
reinforces the slab and the only other reinforcement required is
welded wire fabric for controlling temperature and shrinkage cracks.
Wheeling
Super-Bond floor deck is engineered as a ribbed profile deck with
special rolled-in embossments designed to interlock with the concrete
slab. This construction makes maximum efficient use of both the
steel and the concrete. Composite beam design utilizing composite
floor deck and shear studs provides an economical concept, allowing
the designer to reduce the size and cost of steel beams by as much
as 30 percent.
During
construction, Super-Bond deck carries the full load of the concrete.
Shoring may be required on extended spans before the concrete cures
and reaches maximum strength. After the concrete is cured, the full
load is carried by the steel and concrete performing compositely.
Galvanized
Super-Bond composite floor deck is manufactured from steel conforming
to ASTM A653. Two galvanized coating weights are available: standard
G-60 and G-90. Galvanized coating conforms to the requirements of
ASTM A924. Super-Bond composite floor deck is also available with
a phosphatized/painted coating, which is a cost efficient choice
for use in enclosed environments. The painted bottom side of the
floor deck is high-heat baked-on thermal setting primer. Phosphatized/painted
Super-Bond is manufactured from steel conforming to ASTM A611.
Diaphragm
Design - Composite deck slabs can be utilized in diaphragm design
with lateral loading. This type of diaphragm is composed of composite
steel floor deck and structural, normal or lightweight concrete
fill. The concrete fill must have a cover of 2-1/2 inches and attain
a minimum compressive strength of 3,000 psi and WWF temperature
reinforcing meeting SDI requirements. Contact your nearest Wheeling
representative for a Diaphragm Design Manual.
Fire
Rated Floor - Super-Bond deck has been classified by Underwriters
Laboratories, Inc. and listed in the U.L. Fire Resistance Directory
D-series floor assemblies. Spray on fireproofing can be applied
to the underside of the deck to comply with design assembly requirements.
Fireproofing requirements including surface preparation for the
adherence of
fireproofing products is the responsibility of the fireproofing
applicator and fireproofing manufacturer. See pages CD-18 - 21 for
a listing of U.L. assemblies with classified Super-Bond decks.
The
consulting services of Dr. Larry D. Luttrell, P.E., Professor Emeritus
- West Virginia University, and Luttrell Engineering, PLLC have
been used in the determination of Wheeling's composite deck technical
data.
