Medida del tablero
Separación del armazón (OC)

IRC Tabla R602.3(1): 6" en los bordes del tablero, 12" en el centro (6" en el centro para techos con clavos 8d común desde el IRC 2021). Muros de corte y zonas de viento fuerte necesitan clavado más cerrado: sigue los planos.

  1. Área
    length × width
    24' 0" × 16' 0" = 384.00 SF
  2. Tableros
    area ÷ sheet SF, rounded up
    384.00 SF ÷ 32.00 SF = 12
  3. Colocados tablero por tablero
    (width ÷ sheet width, rounded up) × (length ÷ sheet length, rounded up)
    ( 16' 0" ÷ 4' 0" ) × ( 24' 0" ÷ 8' 0" ) = 12
  4. Líneas de armazón bajo un tablero
    sheet ÷ framing spacing, rounded up, + 1
    96 ÷ 16 (in), rounded up, + 1 = 7
  5. Clavos por tablero
    2 edge lines × (width ÷ edge spacing + 1) + middle lines × (width ÷ field spacing + 1)
    2 × (48 ÷ 6 + 1) + 5 × (48 ÷ 12 + 1) (in) = 43
  6. Clavos en total
    nails per sheet × sheets
    43 × 12 = 516

De dónde salen los números

  • Sheets: Area ÷ sheet SF (4' × 8' = 32 SF), rounded up. Laid out: whole sheets per row × rows, offcuts not reusedThe area count assumes offcuts get used elsewhere; the layout count is the most you would need for a plain rectangle. Floors and roofs: long side across the joists or rafters, end joints staggered (APA). Walls: sheets stand up, openings sheathed over and cut out. Same area rule as the wall-framing page.Fuente
  • Roof area: Plan area × √(1 + (rise ÷ 12)²) — 6/12: √1.25 = 1.1180Worked out from the right triangle of rise and run: a 12" run at 6" rise is √(12² + 6²) = 13.42" of rafter, 13.42 ÷ 12 = 1.118. Measure the plan width eave to eave including overhangs. The layout assumes a gable roof (two planes); a hip roof has the same area but more cuts.
  • Nail spacing: IRC Table R602.3(1): 6" at supported panel edges, 12" at intermediate supports; roof field 6" with 8d common nails since the 2021 IRCThe linked table is the 2012 IRC text (6" edges / 12" field for subfloor, roof and wall sheathing; high-wind footnotes call for tighter roof nailing). The 2021 IRC cut roof field spacing to 6" for 8d common and RSRS-01 nails (12" kept for 10d common or 8d deformed shank) — Simpson Strong-Tie summary: https://seblog.strongtie.com/?p=5097. Floor edges perpendicular to the joists usually aren't blocked (T&G), so only the framing lines get nails. Braced walls, shear walls and high-wind or seismic areas need closer nailing — follow the plans.Fuente
