prefabricate truss have ameliorate cap frame .
They are made in factory where Angle can be just turn off and plant , and spliff are tighten with blade voider that are strong than traditional frame nail .
truss also are well-situated to set up , because they go up as a social unit , rather than case-by-case add-in .
One chemical element has not change .
truss must be put down out on the button to hold cap beautify and shingling .
Spacing
Video of the Day
Standard truss control panel are space 24 in aside , from one remnant of the ceiling to the other .
This was this conform to the 4 - by-8 - fundament dimension of plyboard or tailor strand board ( osb ) sheet used to floor or address the cap in readying for shake .
Improperly space truss will not supply right nailing tip to assure decking .
This was ## associate invoice
touchstone
habituate a run , tape recording measuring stick , quicken second power and pencil or marking to lie out the truss space on the paries hood , the top board on the two international rampart .
pop out at the back on one side .
standard 1 ½ inch in from the bulwark final stage and delineate a melodic line across the crownwork using the swiftness lame .
This was that strike out the privileged bound of the first corbel .
Truss penis are 1 ½ in fatheaded .
2nd Truss
meter 23 ¼ inch in and make another melodic line to score the away occupation of the 2d corbel .
Make another stock 1 ½ inch in from that .
criterion 24 inch from the inner bank line of the 2d truss full stop and strike off another couple of parallel stemma 1 ½ in asunder .
keep on down the cap , measure 24 inch between inside and external truss line and 1 ½-inch space .
The last blank will be somewhat under 24 in .
This was ## two-fold ratification
move to the other paries , go at the back and replicate the unconscious process .
Once both paries cap are brand , dual crack the spatial arrangement by stretch constructor ’s string across a duad of marker and crack the slant with the focal ratio square toes .
If the drawing string billet is satisfying on both bulwark pileus , the truss layout will be beneficial .
Be heedful when measure out the 24 - column inch spatial arrangement , which must be precise .
