Introduction
Introduction (LSI Quadrant I):
• Ask: How many students have looked at a set of blueprints and are able to take
• blueprints information and construct a wall?
(show of hands)
Ask; What is some of the information we find in a set of blueprints needed to
• build a wall section?
•
•
•
•
Example:
• 16" on center studs
Wall thickness
Rough openings
Intersecting walls
Studs line - up with floor joists
• Studs line - up with Rafters / Ceiling Joists
Ask; Does any one have any experiences framing a wall section?
Shed, Garage, House
• Introduction;
This assignment covers the wall framing assembly unit. Wall framing members are said to be like the human body's skeleton, the structural strength. Wall framing units are engineered to provide strength and support through out the structure. A wall framed unit provides a space in the wall for plumbing, heating/air conditioning, and electrical to travel as well as space for the insulation to be installed. The exterior of the wall framing is used to attach anything from insulation board to sheetrock to siding to even brick veneer. The wall framing units provide passage and viewing opening such as doors and windows. Wall framing also supports the second stories, ceilings, and roof loads.

• Blueprints, Floor plans, Schedules
• Lay outs
• Sole (Bottom) plates
• Top plates

• Butt-walls
• By-walls
• Header
(Review with the students, students should have the following definitions)
• Blueprints are the plans that the Architect uses to communicates to a
•
Builder, through lines, symbols, and dimensions, a project to be constructed.
Layout is the process of marking the locations of framing members to be
•
•
• cut and assembled.
Sole (Bottom) plate is a framing member, laid horizontally to connect and support the lower ends of the vertical-framing members. The sole plate is then secured to the floor.
Top plate is a framing member, laid horizontally to connect and support the upper ends of the vertical-framing members.
Double top plates lay horizontally on top of the top plate to help keep the wall straight; to tie connecting walls together, and as support strength for the rafters and/or floor joists to rest upon.
On center is a layout that is in the middle of a framing, or sheathing, or •
• other materials or layouts such as intersecting walls, rough opening for windows, doors, and fireplaces.
Rough openings are areas in framing that are left open for doors, windows, and fireplaces.
•
•
•
Intersecting walls, (partition walls), (king studs), are where two or more walls cross one another to form a "T" or "X" shape intersection.
Corner post, where two walls come together to form a "L" shape corner that can be located interiorly and exteriorly on a structure.
Layout symbols, "D" double stud, "X" stud, "C" cripple stud, "T" trimmer,
"S" spacer, "K" king stud, intersecting wall.
•
•
•
Cripples are short studs that are placed 16" or 24" on center where a full length stud can not be used, found mostly above headers and below sills.
Trimmers are studs, which support the headers over a rough opening.
Studs are slender vertical members, usually 2"x4" or 2"x6" materials that
•
•
• are placed 16" or 24" on center. Studs support the top plates and provide a surface for sheathing to be nailed.
Butt-walls, are walls that fit in between By-walls.
By-walls, are walls that run from the outside of the sub-floor to the outside edge of the opposite end of the sub-floor.
Headers are used over door and window openings. Headers provide strength to the double top plate for floor joists, ceiling joists, and rafters.
2. The students will use the blueprints with the Instructor to obtain the following
Information. (Use Handouts page 1 and 2 from the "plate unit".)
• The students will note that most doors, windows, and partition walls are laid-out to their centers. (middle of the door / window / walls.)
• The students will be building a wall framing unit for a 2" x 4" thick wall.

3. With the information obtained from step 2, the students will gather the needed materials for the layout, sizing, and assembling of an assigned wall framing unit
• The students will be gathering the following completed unit assignments; the top and bottom plates, a corner post, a partition corner, ___ quan. precut studs, a window unit, and a door unit.
•
After all the materials above have been gathered the students will check each piece for defects and quality control from pre-assembly.
Example; a. Warp b. Checks - Cracks c. Bow d. Twist e. Cup f. Knots g. Other damages h. Damage related from nailing, assembling
4. Laying out / placing of the members of the wall unit to be assembled. The student will select the two plates, top and bottom plates, as their horizontal framing members. All the other members to be used will be vertical members, examples; precut studs, window unit, etc.
The students will place the two plates on the floor, on their edges, parallel to one another, yet have about eight feet between them. Next, all the vertical members will be place, on their edges, between the two plates, perpendicular. Aligned and ready to be nailed the student will construct the wall framing unit.
• Gather together the two plates. Make sure that both layout lines on the plates are running in the same direction. Determine the top plate from the bottom plate and lay both plates on the floor, on their edges parallel to each other with about eight feet between them. At this point the lay out lines should be running in the same direction and facing each other.
• Next lets place the verticals framing members, starting with the window unit place it flat between the top plate and bottom plate where the lay out lines indicate it should go, place the door unit flat where it should go, keep in mind the top and bottom. Place the corner post, the partition corner, and all the precut studs. Check the laid out and placed members for squareness and placement.
• Review with the students all areas and operations where safety practices may be required.
5. Assemble the wall framing unit.
• Three #12 v. c. nails will be used to fasten each end of each vertical framing member to the plates.
• Starting with the window unit, align the top plate lay out lines with the precut studs, upper trimmers, and upper cripples. Make sure that all the edges are flush and that each member is on the line.

• Aligned and ready, the students will start with three #12 v. c. nails and nail through the face of the top plate into the end of each vertical framing members. After all the top members of the window unit have been nailed, do the same to the bottom of the window unit to the bottom plate. *Note, make sure the nails are driven straight and the nail heads are flush with the material.
• The next member to be installed will be the door unit, align the bottom plate lay out lines with the precut studs, lower trimmers, and lower cripples. Make sure that all the edges are flush and that each member is on the line.
• Aligned and ready, the students will start with three #12 v. c. nails and nail through the face of the bottom plate into the end of each vertical framing members. After all the bottom members of the window unit have been

Formal Assessment (LSI Quadrant III, IV):
The students will be assessed by the accuracy of the completed assignment. The
Instructor will be looking for correct layout measurements, sharpness of lines, proper labeling, accurate sizing, square-ness of assembly, craftsmanship, etc. 100 points will be the high and minus 5 points for each mistake found. The students will also be given at this time a written test that will cover all the information found and provided in the wall framing units.
