Generated explanation

Four cutaway floor assemblies illustrate sheet subflooring, tongue-and-groove planks, diagonal planks, and plain planks supported by wood joists. The sheet option is labeled plywood or waferboard, with joist spacing indicated as 12–24 inches, typically 16 inches. An annotation states that plywood is typically 5/8 inch thick for joists at 16-inch centers and that planks are typically 3/4 inch thick. The diagonal plank assembly includes blocking to support the plank ends. The other plank assemblies show boards running perpendicular to the joists, with interlocking edges illustrated on the tongue-and-groove version.
