Determining the location of the ties requires consideration of two factors when comparing
stud spacing and tie-wire spacing:
If the maximum tie-wire spacing is less than the maximum stud spacing, reduce the
maximum stud spacing to equal the maximum tie-wire spacing and install the tie at
the intersections of the studs and wales or get a stronger wire.
If the maximum tie-wire spacing is greater than or equal to the maximum stud
spacing, use the size for the maximum stud spacing and install the tie at the
intersections of the studs and wales.
EXAMPLE:
Determine where the ties will be made if the--
Maximum stud spacing is 28 inches.
Maximum tie-wire spacing is 24 inches.
Reduce the stud spacing to 24 inches, and install the tie at the intersections of the studs and
wales.
Problem 18. Work the following problem to see how well you understand the concept
covered in step 14. The solution to this problem is found at the end of the lesson. Determine
where the ties will be made if the--
Maximum stud spacing is 14 inches.
Maximum tie-wire spacing is 20 inches.
Step 15. Determine the number of studs for one side. Determine the number of studs for one
side of a form by dividing the form length by the maximum stud spacing (step 7 or step 14 if
the stud spacing has been reduced). Add 1 to this number. If the answer contains a decimal,
round up to the next whole number. The first and last studs must be placed at the ends of the
form, even though the spacing between the last two studs may be less than the maximum
allowable spacing. Compute as follows:
length of form (ft) x 12 (in)
Number of studs =
+1
(15)
maximum stud spacing (in)
20
