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 spacer between the members For 2x4 stud wall a 3- 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 thick May be a structural material and/or an insulating material Often applied to frame wall prior to wall being raised from the subfloor 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
