House Framing Ceiling Joists

If trusses are being used, the trust layout will be provided from
truss manufacturer. The bottom chord of the truss will be
the ceiling joist. Trusses will be laid out and installed as
provided by the truss manufacturer. If trusses are not being
used, regular 2x6 lumber or larger will be used for ceiling joists
depending on the structure. Regular ceiling joists layout is 16
inch on center. However, 24 inch on center can be used but will
require 5/8 sheet rock on the ceiling. Once all the ceiling joists
are laid out and installed, it will be necessary to install
deadwood and blocking where needed in order to secure sheet
rock. If
Ceiling joists are butted together on top of a wall, it is
normally good practice to block the joint. The other alternative
would be to lap the ceiling joists at least 6 inches. When trusses
are used, the manufacture will provide a specific detail for
bracing the bottom cords of the ceiling joist. When regular
framing lumber is used for ceiling joists, the ceiling joists will
require a strong back nailed across the top. The strong back is
run perpendicular and normally in the center of a room’s ceiling
joists. The
strong back is made up of a 2x4 nailed flat on top of
the ceiling joists with 2x6 nailed vertically to the side of the 2x4.
The end of the ceiling joist along the exterior walls will require
the top corner to be cut off. This cut is the same angle as the
pitch of the roof. This prevents the end of the ceiling joists from
sticking up above the roof. Once all the ceiling joist are nailed
and secure, the
rafters are ready to be laid out and installed.
