The installation of your
floor system will depend
on the design of your
house. The guidelines we
will use are 24ft wide x
48ft long with a
cantilevered bay window.
The floor joist will be 2inch
x 10 inch we will space at
16inch centers. The girder
and sill plates you learned
how to install in part 1.The
first thing that we are
going to want to do is
square up our floor or
foundation. This is a
repeat process and the
reason for this is you will
want to constantly check
for squareness

A typical interior wall has a
skeleton of vertical 2
-
by
-
4 studs
that stand between horizontal 2
-
by
-
4 base and top plates. (However, if
a wall will contain extensive
plumbing, it should be built from 2
-
by
-
6 studs and plates.) The
framework is typically covered with
gypsum wallboard (water
-
resistant
"green" wallboard near a bathtub
or shower), tile backerboard and
tile, or lath and plaster.


The basic principle of the
traditional roof construction
is to bring load
-
bearing
cross walls up into the roof
space to support horizontal
running purlins . These are
large section timbers onto
which the rafters are fixed
at regular intervals, to
support the roof coverings.
When large spans are
involved, the purlins can be
replaced with lightweight
steel beams, and timber is
then placed on top of
these, so that rafters can
be fixed.


You should hang your
ceilings first so the walls can
help support the ceiling
sheets.

Mark the joist locations along
the wall top plates so they
are easy to find once
covered. Use screws for best
results. They provide more
holding power than drywall
nails. Usually it is best to run
the panels perpendicular to
the joists. Also applying
construction adhesive to the
joist will help provide a better
hold.
