How to Strengthen Prefabricated Trusses
The use of prefabricated trusses is gaining popularity in the construction of both commercial and residential wood framed structures. Adding some additional support to these pre-engineered structures can be quite simple, provided you follow a few basic rules.
Step 1 - Measure the Cut
The most effective way to install bracing of any kind is by creating an isosceles triangle with your support members. Since you’ll be working within the framing of the prefabricated trusses, you’ll just need to cut the 2 side members. Once you determine the point along the truss you wish to support, simply measure the 2 equal legs of the triangle.
Step 2 – Install the Bracing
When making the end cuts for the 2 supporting members, measure the angle so that they’ll be flush with both the top and bottom plates of the pre-fabricated trusses. Measure the angle, then transfer it to the bracing, and use the circular saw to make the cut on both ends of the lumber. Then, use the hammer or nail gun, to secure the bracing in place. You’ll want to use at least 2 nails on each side of the bracing, to make sure it’s secure.
