Floor Truss Blocking

Measure the length between the two joists.

Floor truss blocking. I joists offer only one bearing condition. Parallel chord roof trusses and energy heel trusses often exceed a 15 heel height and have need for this more elaborate method of blocking. Hammer your nails. Blocks blocking panels and structural panels plywood osb are all acceptable.

The lumber should be the same depth as the joist. Floor trusses offer four different bearing conditions for a wider variety of uses. No these are not a substitute for blocking. The multiple bearing conditions make matching existing floor heights much easier when using floor trusses.

Truss a pre built component that functions as a structural support member. In the field float blocks under the edge of the remaining subfloor and screw them through the subfloor. Cut the lumber to fit between the two joists. Is the combination of roof sheathing gypsum wallboard on the ceiling and a hurricane clip on one side of a truss an acceptable substitution for solid blocking.

Toenail them once that s done. Along the wall at the top of your photo simply cut blocks that fit snugly between the trusses and toenail them in place. These are the steps to take to install blocking. Bottom chord bearing bottom chord bearing trimmable ends top chord bearing and mid block bearing are all available.

This allows you to find the distance in lumber you need to cut. For example if you have.
