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

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

3. 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

4. Wood Frame Wall Construction Materials

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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
