(2) Details. Details are largescale drawings which show
features that do not appear (or appear on too small a scale) on the
plans, elevations, and sections. Sections show the builder how
various parts are connected and placed. Details do not have a
cuttingplane indication but are simply noted by a code. The
construction of doors, windows, and eaves is usually shown in detail
drawings. Figure 112, page 114, shows some typical doorframing
details, window woodframing details, and an eave detail for a simple
type of cornice. Other details that are customarily shown are sills,
girder and joint connections, and stairways.
Figure 113, page 115, shows how a stairway is drawn in a plan and
how risertread information is given. For example, on the plan, DOWN
17 RISERS followed by an arrow means that there are 17 risers in the
run of stairs going from the first floor to the floor below, in the
direction indicated by the arrow. The risertread diagram provides
height and width information. The standard for the riser, or height
from the bottom of the tread to the bottom of the next tread, ranges
from 6 1/2 to 7 1/2 inches. The tread width is usually such that the
sum of riser and tread is about 18 inches (a 7inch riser and 11inch
tread is standard). On the plan, the distance between the riser
lines is the width of the tread.
