How to Build a Simple Deck : 5. Install Front Rim Joist, Beams, and Interior Joists

5. Install Front Rim Joist, Beams, and Interior Joists

Fasten concealed-flange double joist hangers on the ends of the front rim joist’s inner 2xs. Then fit the inner 2xs into the post bases.

Fit a side rim joist into a front hanger, and square the corner. Secure the front rim joist 2x to the post bases with hanger nails. Then drive six 16d nails through the face of the front rim joist into the end of the side rim joist. Repeat with the other side rim joist.

Fasten face-mounted double joist hangers for beams every 8 feet on center along the front rim joist and ledger, flush with their bottom edges.

Fit and nail each beam as described above.

Complete the doubled front rim joist by gluing and nailing the outer 2xs to the inner 2xs.

Install 2x joist hangers along the beams, 16 inches on center. (Joists, once inserted, should be flush with the top edge of the ledger, rim joists, and beams.)
