STICK WITH THE PLAN

摘要

Perhaps the most important element in framing a truss roof is the plan provided by the truss manufacturer. It identifies every truss and truss location with a three- or four-digit code. A paper label attached to the truss corresponds with the coding on the plan. The plan is so important that Portland-area truss manufacturers laminate the drawing so that it can stand up to the area's notoriously wet weather. Plan in hand, the framer decides where to start and in what order he'll lift and set the trusses.
