Wood Framing F 09 Presentation Transcript

  • 1. Light Wood Frame Construction Framing Methods Floor Systems Wall Systems Roof Systems Wood Terms IBC - Type 5 Construction Professor Richard Luxenburg, AIA Anne Arundel Community College Department of Architecture and Interior Design Fall 2009
  • 2.
      • L arger (5”x5” min) and fewer members (spaced further apart 2’,4’,6’, 8’o.c)
      • IBC - Type 4 Construction (different code requirements)
      • D iagonal bracing or rigid connections required for lateral stability
      • Exposed construction (no cavities)
      • T ends to be Very Expensive – guess why?
    LWF (light wood framing) is Not Heavy Timber Heavy Timber is:
  • 3. Light Wood Frame Construction………………………….(like a light balloon!) http:// www.canforcentre.com/system.html
  • 4. Light Wood Frame Floor Systems
    • Wood Joist System
      • Relatively small joist members (2 x10 etc.)
      • closely spread
      • (12”, 16”, 24” o.c)
      • Short spans for subflooring, underlayment and gypbd. clg.
      • Joists supported by
      • beams or walls
      • Flexible in form & shape
      • (unlike grid of post & beam)
  • 5. Heavy Timber section of a light wood framed (LWF) house.
  • 6. House-wrap (Dupont Tyvek) over panelled sheating. Explain why! Moisture/air infiltration. http://www.tyvek.com/whatistyvek.htm http://www2.dupont.com/Tyvek_Construction/en_US/products/residential/products/thermawrap.html
  • 7. Project No. 1 Here’s a project you’re going to have to do this semester! So pay attention! That’s a student’s bass wood ( not balsa wood) model!
  • 8.  
  • 9. Wall Systems
    • Wood Stud Walls
      • 2 x 4’s or 2 x 6’s
      • 16” or 24” o.c.
      • Insulation
      • vapor barriers
      • Interior finish (gypsum)
  • 10. Framing Methods
    • Studs sit on a platform of plywood
    • (decking/sheathing) between floors
    Studs continue from foundation to roof Platform Balloon Framing
  • 11. Framing Methods - Balloon Frame
  • 12. Framing Method - Platform Framing
  • 13. Wood Terms
    • Joist : horizontal or sloped framing member
    Rafter: sloping framing member for the roof Stud: vertical framing member
    • Beams
    • Columns
    “ Stick built ”– not using pre-fab trusses (like the next slide) but instead using individual 2x rafters ceiling joist floor joist stud rafter

  • 21. Wood Terms
    • Blocking
      • Solid piece of isolated wood (stud) placed between framing members (walls, floors, roofs).
      • Usually for support or attachment of something else.
    blocking
  • 22.
    • Bridging
      • Material between framing members (continuous) to evenly distribute loads
      • Keeps framing members from twisting
        • Solid blocking
        • Diagonal bridging
          • Wood
          • Metal
    blocking bridging
  • 23.
    • Sheathing - material covering the framing members (roof, floor & walls)
        • Plywood (typically 4’ x 8’ modular sheets) roll sliced lumber
        • OSB (oriented strand board) reconstituted (recycled) wood
        • Boards (cut lumber)

  • 26. The true measurement of a 2x4 is actually about 1.5x3.5. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. The lumber is then sold as a "2x4" because the cost of the drying and machining are figured in ... it is also much easier to refer to a board as a "2x4", rather than a "1.5x3.5".

    • Soundproofing Products
    • Acoustiblok ® is a unique 1.1 lb. psf U.L. Classified, high S.T.C. reinforced dense noise isolating material for reducing sound transmission. is approved by U.L. for walls, ceilings and floors (see U.L. classification. It is usually stapled to wood studs
    • Each layer of 16 oz Acoustiblok ® reduces sound transmission by as much as 30 db depending on the frequencies.  
    • A typical 2 x 4 gypsumboard stud wall is usually 33 to 35 STC. Acoustiblok® installed in the 2 x 4 wall is lab certified at an amazing "STC of 52", better than 12" of poured concrete (STC 51).
