14. What is the maximum span of a 2' x 12' exterior header
in a one-story building (Page 6.2, Section 2.0.0)?
Answer
12’
15. How is a corner (corner post) built (2 methods) (Page
6.3, Section 2.1.0)?
Answer
1) Two common studs faces sandwich 3 blocks
spaced top bottom and middle. 2) Two common
studs one nailed face flush with the edge of
another. A third is part of an adjoining wall at
right angles
16. What is a truss header (Page 6.6, Section 2.3.2)?
Answer
A special header that holds of a heaver than
normal dead load
17. What is the spacing of wall studs generally speaking
(Page 6.8, Section 3.0.0)?
Answer
16” O.C.
18. What is the measurement that is used to establish the
position of the first stud from the corner in a wall (Page
6.8, Section 3.0.0)?
Answer
15 ¼” (to the side)
19. What are the actual dimensions of a door marked
"3668" on a floor plan (Page 6.9, Section 3.1.0)?
Answer
3’-6” wide by 6’-8” tall
20. What is the standard distance from the floor to the
underside of the window’s head jamb (Page 6.10, Section
3.1.0)?
Answer
6’-8”
21. What combined measurements make up the width of a
header for a window or door rough opening (Page 6.10,
Section 3.1.0)?
Answer
The Window unit width, thickness of the jamb
material, spaces on each side for shimming, and
two trimmer stud thicknesses. A rough opening
width is the same measurement without the
trimmer stud thicknesses.
22. How does a carpenter obtain the measurement for the
total width of a rough opening (Page 6.10, Section 3.1.0)?
Answer
Take the unit width add the jamb thickness on both
sides add ½” on both sides for shim clearance. Example
– a window that is 32” wide will usually have a jamb
thickness of ¾” so the rough opening is 32”+ 2(3/4”) +
2(1/2”) = 34 1/2” for a R.O. width.
23. What are the markings used for king studs, Common
studs, trimmer studs, and cripple studs (Page 6.11, Section
3.1.0)?
Answer
King studs >
X
Common studs > X
Trimmer studs > T
Cripple studs > C
24. What should the height of the stud be for a building
that has a 1/2" sheetrock ceiling, a 5/8" underlayment, a
3/4" subfloor, and an 8' ceiling height (Page 6.13, Section
4.0.0)?
Answer
Take the desired ceiling height subtract the
thickness of the three plates. Then add 5/8”
underlayment and 1/2” sheetrock ceiling. Example
8’ converted to inches = 96” subtract the plates a
total of 4 ½” leaves 91 1/2” add 5/8” and 1/2” to 91
1/2” to equal 92 5/8” (ignore the 3/4” as the wall
sits upon the subfloor.)
25. How does a carpenter calculate the length of a cripple
stud above a door rough opening (Page 6.14, Section
4.0.0)?
Answer
Using the common stud length, subtract from it
the rough opening height and the thickness of the
header (vertical measurement of header above the
R.O.) and the thickness of the sole plate. What
remains is the length of the short cripple stud.
Example – Using a common stud length of 92 5/8”
and a rough opening height of 82 ¼” and a header
thickness of 3 ½” yields… 92 5/8” – (82 ¼” + 3 ½” +
1 ½”) = 5 3/8” long cripple studs.
26. What are fire stops (Page 6.15, Section 5.1.0)?
Answer
Short pieces of 2 X 4 blocking (can be other
materials if code allows) nailed horizontally at mid
common stud height. (Similar to bridging in
between joists) . It is supposed to stop the rush of
air, smoke, gases or flames from traveling up a wall
cavity. Code usually also requires holes drilled to
be calked or plugged in some approved manner.
27. When erecting a wall what prevents it from sliding off
the platform as it is being pushed up to a vertical position
(Page 6.16, Section 6.0.0)?
Answer
Cleats nailed to the head or end joist
28. What is done to hold the wall frame erect and plumb
(Page 6.16, Section 6.0.0)?
Answer
Nailed through the sole plate and then temporarily
braced.
29. How is the top of a wall made straight (what is used
and how is it used) (Page 6.17, Section 6.1.0)?
Answer
Stretching a string from corner to corner which is
pushed out at both ends by the thickness of a 2 X
4 block. A third block is slid between the wall top
plates and the string. Space between the block an
the string means the wall must be pushed outward
at that location. If the block moves the string
because the space is too small, the wall must be
pushed inward at that point.
30. What are four types of framing bracing methods (Page
6.18, Section 6.1.1?
Answer
Notched or Let-in bracing or 2 X 4 braces at each
corner. Plywood sheet. Metal strap, and metal
bracing
31. If APA-rated sheathing is used to cover the building’s
exterior, how far apart should the nails be spaced when
nailed into the intermediate studs (Page 6.19, Section
6.1.2)?
Answer
12” apart
32. What other materials besides plywood and OSB may be
used as sheathing (Page 6.19, Section 6.1.2)?
Answer
Fiberboard, exterior rated gypsum wallboard, rigid
foam sheathing.
33. What should the thickness of the plywood sheathing be
if a carpenter is constructing a building where siding will be
applied over the sheathing (Page 6.18, Section 6.1.2)?
Answer
Minimum thickness is 3/8”.
34. Which way are ceiling joists typically positioned on a
building (Page 6.19, Section 7.0.0)?
Answer
They span the narrow dimension
35. If ceiling joists have to be spliced what should the
minimum overlap of the joist ends be (Page 6.20, Section
7.0.0)?
Answer
No less than 6”
36. What must be done to the outside edge of the ceiling
joists (Page 6.21, Section 7.1.0)?
Answer
Ends must be cut to match the angle of the
rafters so that the upper corner does not
protrude into the roof line.
37. How many pieces of 16' lumber are needed for the
soleplates, top plates, and double top plates of a building
32' wide and 48' long (excludes partitions) (Page 6.23,
Section 8.0.0)?
Answer
Perimeter problem 2L + 2W - 3 times once for
each type of plate. Then divided by 16’. Example
3((2 X 48’) + (2 X 32’))/16’ = 3((96’) + (64’))/16’ =
480’/16’ = 30 16’ long pieces of lumber.
38. How should a carpenter proceed to create the lay out
of ceiling joists for a hip roof (Page 6.19, Section 7.0.0
Note)?
Answer
Start at each building corner and work toward the
middle.
39. What determines the stud spacing when constructing a
non-bearing wall with metal studs (Page 6.28, Section
10.0.0)?
Answer
Type and thickness of the drywall
40. What quality should lumber have if it is used in contact
with masonry (Page 6.28, Section 10.1.0)?
Answer
Pressure treated
