Generated explanation

The perspective drawing shows wood roof rafters, ceiling joists, and supporting stud walls with top plates. A plywood panel is nailed across the tops of several ceiling joists at their splice locations. The annotation identifies a 2- to 3-foot-wide plywood piece as a high-quality connection that also helps distribute the load. Secure ceiling joist splices allow the joists to adequately restrain the ends of opposing rafters.
