Laying Out The
Top And Bottom Wall Plates
Lay out the wall
location on the sub
floor where the wall's bottom or
sole plate will be positioned. Measure from the outside edge of the
subfloor, the width of the sole plate plus the sheathing, if the
sheathing extends to the sub floor; or the width of the bottom plate if
the sheathing extends over the boxing joist to the concrete foundation
wall. Snap a chalkline.
Select straight stock for the bottom
and top plates, square of one end
of each plate, and lay them side by side on the subfloor. If the plates
have to be made out of more than one piece of lumber, make
they join over a stud centre. See figure 27.
Measure and mark the locations of the door and window opening centres,
openings located from centres, partitions and studs. This information
is provided on the blueprint.
To locate the openings on the plates, measure one half the distance on
each side of the opening and mark the positions. On the other side of
the marks, write C for cripple (or sometimes T for trimmer). Mark lines
on the other side of, and one studs distance away from each C mark.
Mark X's for studs on the far side of the lines marked. Write the name
and size of the opening on the
Mark the locations of partitions P,
blocking B, And corner studs X.
From one wall corner to the next,
mark the stud locations with Xs. The
distance of the first stud from the corner is reduced by half the width
of the stud. Omit stud locations that fall on cripples or partitions.
Place a stud beside the cripple or partition if it falls half
and off during the layout. Never increase the distance between studs
when you place this stud.
