FLOOR/CEILING ASSEMBLY:
Use a fire-rated floor/ceiling assembly consisting of normal
weight or lightweight (minimum 105 pcf, 1682 kg/m3) reinforced concrete. Thickness of concrete
Floor ceiling assembly must comply with designated fire resistive rating.
2.
FLUTED STEEL FLOOR UNITS:
Corrugated steel decking, minimum 1-1/2” deep (38mm),
minimum 20 Ga.
3.
STEEL STRUCTURAL BEAM:
Use steel sections, I-beam or W-beam, sized in accordance with
the Table CC/BA 180-01.
4.
FIRE-RESISTIVE COATING:
Refer to Table CC/BA 180-01 for specific application thickness of
fire resistive coating.
A.
Intumescent Fireproofing:
Spray or paint in one or more coats according to manufacturer’s
instructions to a nominal 1/2 the required thickness or 0.12” (3mm) (whichever is smaller) before
applying fiberglass mesh (Item 4B). Spray or paint in one or more coats according to manufacture’s
instructions to required final thickness after installing fiberglass mesh (Item 4B).
CERTIFIED PRODUCT:
Fire Resistive Coating. MODEL: Thermo-Lag 3000
B.
Fiberglass Mesh:
For final thickness of the intumescent fireproofing (Item 4A) of 0.24” (6mm) or
less install mesh at middle depth of the intumescent fireproofing (Item 4A). For final thickness of the
intumescent fireproofing (Item 4A) greater than 0.24” (6mm), install fiberglass mesh at 0.12” from
structural steel beam (Item 3). Wrap fiberglass mesh completely around bottom flange. Overlap
fiberglass mesh a minimum 1/2” (13mm) at seams.
