2.2.1
Adjusting Plates
Provide adjusting plates, or segments of deck units, of same thickness and
configuration as deck units in locations too narrow to accommodate full
size units. Provide factory cut plates of predetermined size where
possible.
2.2.2
End Closures
Fabricated of sheet metal by the deck manufacturer. Provide end closures
minimum 0.75 mm 0.028 inch thick to close open ends at [exposed edges of
floors,] [parapets,] [end walls,] [eaves,] [and] openings through deck.

Partition Closures
**************************************************************************
NOTE: Coordinate options in paragraphs entitled
"Partition Closures" and "Closures Above
Partitions." When a suspended acoustical ceiling is
provided below the metal deck, the closures above
partitions may be eliminated for acoustical purposes
provided the acoustical properties of the ceiling
are adequate to restrict sound transmission to a
level consistent with the facility design criteria.
**************************************************************************
Provide closures for closing voids above interior walls and partitions that
are perpendicular to the direction of the configurations. [Provide rubber,
plastic, or sheet steel closures above typical partitions.] [Provide
minimum one inch thick soft composition rubber closures above walls and
partitions contiguous to acoustical steel deck.] [Provide sheet steel
closures above fire-resistant interior walls and partitions located on both
sides of wall or partition.] [Provide glass fiber blanket insulation in
the space between pairs of closures at acoustical partitions.]
**************************************************************************
NOTE: Drawings shall show closures above interior
partitions where required. On fire partitions,
metal closures will be shown on both sides of the
wall.
**************************************************************************
2.2.4
Closure Plates for Composite Deck
The concrete shall be supported and retained at each floor level. Provide
edge closures at all edges of the slab of sufficient strength and stiffness
to support the wet concrete. Metal closures shall be provided for all
openings in composite steel deck 6 mm 1/4 inch and over.
2.2.5
Sheet Metal Collar
Where deck is cut for passage of pipes, ducts, columns, etc., and deck is
to remain exposed, provide a neatly cut sheet metal collar to cover edges
of deck. Do not cut deck until after installation of supplemental supports.
