Out And Installing Floor
Layout and install the
See figure 22. Layout the boxing or header joists
on both long walls first.
Joists should be cut so they join on the centre of a floor joist. Lay
out the floor joists positions on the sill plate. If the floor joists
are placed at 400 mm (16.5 inches) centres, the outside edge of the
first joist will
be at 380 mm (15.25 inches). If the joists are butted to a beam or load
the layout is the same on both sides. If the joists are
the layout of the joist and sheathing plywood on one side will be
reduced by the thickness of one joist. Setup and plumb a boxing joist
on one side. Toenail it to the exterior side of the sill plate with
82 mm nails, midway between floor joist centres. Setup, plumb and nail
the floor joists on that side; then do the same for the other side.
Leave the floor opening framing until last. According to the BC
Building Code 1998, Page 346, Table 18.104.22.168, the floor joist should be
toe nailed to the plate with two 82 mm (3.25 inch) nails and the header
should be end nailed to the floor joist with five 82 mm (3.25 inch)
that too few nails used will weaken the structure, and too many nails
will probably breakup the structure and weaken it.
