Blocking the Joists
Install blocking between joists to prevent twisting, especially on spans longer than 8 feet. Measure each piece of blocking separately to allow for any difference in the thickness of the joists. This will keep the blocking from bowing the joists.
Mark Position for Blocking
Snap a chalk line across joists at the center of the joists. This line locates the position for blocking pieces.
Fasten the blocking between the joists with 3-inch galvanized spiral-shank nails or 3-inch screws. Attach blocking between adjacent joists on opposite sides of the chalk line to allow you to face-nail the fasteners.
Attach Joists to the Beam
Attach the joists to the beam with rafter/hurricane ties. Install ties on the less-visible side of the beam, if possible, driving the kind of nail specific by the manufacturer through every nail hole in the connector.
