CEILING FRAMING
LEARNING OBJECTIVE: Upon completing
this section, you should be able to state the
purpose of ceiling frame members and describe
layout and installation procedures.
Ceiling construction begins after all walls have been
plumbed, aligned, and secured. One type of ceiling
supports an attic area beneath a sloping (pitched) roof.
Another type serves as the framework of a flat roof.
When a building has two or more floors, the ceiling of
a lower story is the floor of the story above.
One of the main structural functions of a ceiling
frame is to tie together the outside walls of the building.
When located under a pitched roof, the ceiling frame
also resists the outward pressure placed on the walls by
the roof rafters (fig. 1-60). The tops of interior partitions
are fastened to the ceiling frame. In addition to
supporting the attic area beneath the roof, the ceiling
frame supports the weight of the finish ceiling materials,
such as gypsum board or lath and plaster.
