• Wall Framing of Own Home - Hooks / Set

  I ask the students to share with their table mates or in groups of 3 or 4 as to what they think  a wall is made up of.  After 3 minutes we will share out . At this point I will ask a series of questions. What is a purpose of a wall?  I will ask, " Has anyone helped build a wall? Has anyone ever demolished a wall?"  I will ask does any one know exactly how tall a wall is? I will then bring out a model house to show as an example what their project may look like.

• Lecture 1 - Wall Framing - Framing Detail - Lecture

  This is a Lecture where students will enter selected information into their portfolios. The selected information will be listed on the white board. Students will be introduced to 2" x 4" Douglas Fir, 4" x 12" Douglas Fir all rated Number 2 or better. This a minimum rating which is stamped on the wood that is accepted by the Uniform Building Code Agency. The nominal measurement for example for a 2" x 4" is what that is listed. The actual measurement of a 2' x 4' is 1- 1/2 " x 3-1/2". From here on out D.F. will stand for Douglas Fir

  Components of a wall is drawn on the white board (not to scale). Starting with the 

  1) Bottom Plate a 2" x 4 " D.F. installed in a horizontall position at various lengths in even increments from 8 ' to 20'.

  2) Studs a 2" x 4" x 92 1/4" D.F. installed vertical ( with the crown out) every 16" On Center (O.C.) according to the Uniform Building Code (ubc)

  3) Double Top Plate 2" x 4" D.F - Two 2" x 4" horizontal on top the studs parallel  to the bottom plate

  4) Header 4" x 12" D.F. Load Bearing Member above doors and windows in a horizontal position at the very top of doors and windows

  5) Jack Stud 2" x 4" D.F Vertical Supports the header underneath at each ends

  6) King Stud 2" x 4" D.F. Vertical member adjacent to both Jack studs at the outer position

  7) Sill 2" x 4 " D.F. Double 2" x 4"  in a horizontal position at the bottom of a Window

  8) Cripples 2" x 4" D.F.  Short Vertical supports underneath the window sill 16" O.C.

• Lecture 2 - Wall Framing - Bearing Wall - Lecture

  This is a lecture where students will entered selected information into their portfolio listed on the White Board. Students will recognize that a Bearing Wall Is  a Load Bearing Wall. A wall that will hold the weight of the roof.  Typically it is the perimeter walls of a house. There are instances where it also may beinterior walls also.

  When  the studs are installed they are Crowned out . Meaning that if there is any curvature along the face of the wood that is 1 1/2" Across,  looking down the length you might see a bend in the  (See Down Load) wood. The curvature that bends up is called the Crown. That Curvature is placed on one side of the wall, typically the outside of the wall.

  The UBC Studs are placed every 16" O.C. Placement at this measurement creates Structural integrity.  Studs are fastened to the bottom plate, end nailing with Two #16 green vinyl nails. The nailing at the top plate. In lieu of end nailing, you may toe nail with a minimum of 4 #8 Green vinyl Nails (See Down Load). These nailing patterns are also governed by the UBC.

  A Typical Height of a single story residential house is 8 feet. In reality the framing of the wall is actually 8'-3/4 ". When you add the thickness of the Bottom Plate 1 1/2", the height of the stud 92 1/4", and the thickness of the Double Top Plate 3" all that Equals 96 3/4". The Purpose is to accommodate 4' x8' Sheet goods. (See Down Load)
• Lab 1 - Wall Framing Preparing Sub Floor - Lab / Shop
  • Students will be changing their scale from 1/4 " scale to Building their House to a 1/2" scale
  • Students are given a piece of 1/2 " plywood representing the subfloor of their house.
  • The Sub Floor is cut in the  exact  shape of the perimeter of their house (to be cut by the Instructor).
  • Students are to redraw the floor plan of their house now using the 1/2" scale onto the plywood sub floor.

• Lab 2 - Wall Framing Placement of walls onto the Sub Floor
  • Students will be issued a hot glue gun
  • Dove tail saw 
  • Square dowels 3/16" x 1/8" to represent 2" x 4" DF.
  • Students may cut bottom plates up to 8 " to represent 16'.
  • Studs will be cut at 3 3/4 " to represents studs.
  • Studs are Place 3/4 " to 7/8' to Represent 16" O.C.
  • Students are to glue down the bottom plates first . Leaving an 1 1/2" opening where Doors are to be Installed.
  • Students are to place a drop of hot glue every 3 " to 4" at the underneath side of the Bottom Plate.
  • Students are to place bottom plate at the line representing their walls of of their floor plan.
  • Once all bottom plates are installed, students will Install all corner studs and where studs intersect at a wall (See Down Load).
