It s also what establishes the overall height and levelness of the entire deck frame.
Ledger to concrete wall.
Use a pencil to mark the location of these holes on the wall.
Drill two lengths of ledger board for anchors as described above and anchor them both to the solid concrete stacked to.
Install your sleve anchors.
You will likely need two helpers to hold the ends of the ledger board while you get ready to attach it to the masonry wall.
This results in a tensile load on the anchor bolts rather than just a shear loading.
On this project the 2 10 joists of the main deck frame sit just about even with the top of the foundation and a landing framed with 2x8s sits atop the main frame serving as a transition point between the lowered deck and the patio door.
Install two bolts at the end of each ledger board.
One of the benefits of this method is that more rigid minimum and maximum lag screw location configurations associated with mounting to band joists can be avoided.
Tighten the bolts carefully.
Cut pieces of pt 4x4 post to fit from the top of the double ledger support to the bottom of the deck ledger above.
The sagging of the joists causes a rotation of the ledger board and due to the constraint of momvement caused by the concrete wall the ledger board does not rotate about the anchor bolts but rather the lower edge of the ledger that is in contact with the concrete.
Expansion anchors never lead shields are used in solid masonry or filled block and approved epoxy or acrylic anchors and bolts are used in hollow masonry.
Hammer the sleeve anchor through the ledger board into the concrete wall.
Use a wood bit to drill pilot holes through the ledger board.
In most cases deck ledgers can be bolted directly to poured concrete or concrete block walls.
The ledger is not only the structural connection between the deck and the house.
From 2005 nds tab.
