Competency: 206.00 Draw wall sections and details Objective: 206.03 Apply concepts of wood frame wall construction.

Wood Frame Wall Construction Materials Wood studs should Be straight Have good stiffness #2 grade or better Moisture content of 15-19%

Wood Frame Wall Construction Materials 2x4 and 2x6 lumber are most popular sizes for wall construction 2x6 materials can be used for exterior walls for additional insulation thickness 2x4 materials used for most interior walls 2x6 and 2x8 materials used to allow plumbing to pass through wall

Wood Frame Wall Construction Materials

Wood Frame Wall Construction Components Sole Plate/Bottom Plate Holds studs together in a wall unit Anchors wall to subfloor Wall studs Spaced 16” or 24” O.C. Length based on ceiling height Top plate Ties intersecting walls together Provides additional strength between studs where ceiling joists/rafters do not bear directly above the stud

Wood Frame Wall Construction Components Headers Size depends on its span and loading Carries load of the roof where studs have been removed from the wall to create an opening

Wood Frame Wall Construction Components Solid headers Fill the space above the opening Header formed by turning two units of framing lumber on edge with a ½” spacer between the members For 2x4 stud wall a 3-½” thick unit

Wood Frame Wall Construction Components Solid headers Studs are not full length Fill the space above the header Headers are supported by trimmers or jack studs

Wood Frame Wall Construction Components Corner Bracing Plywood, OSB, or similar material may be used in place of the let-in brace Diagonal metal straps may be used

Wood Frame Wall Construction Exterior Finishing Wall sheathing Typically ½” thick May be a structural material and/or an insulating material Often applied to frame wall prior to wall being raised from the subfloor

Wood Frame Wall Construction Exterior Finishing Wall ties Masonry wall is not a load bearing wall Frame wall carries the load of the structure Ties are bent to fit between mortar joints Corrugated metal ties Placed 16” O.C. vertically Placed 32” O.C. horizontally
