As with barn raisings of yore, it takes a few warm bodies to raise framed walls. Let one per­son be the team leader and encourage everyone

Подпись: Temporary braces are important. After raising a wall, make sure it is braced securely with 2x lumber that extends diagonally from the rim joist or the floor to the top of a stud in the wall. Secure bracing eliminates the serious injuries that can result from a falling wall. These braces also help keep walls plumb, straight, and ready for roof trusses.Подпись: Nailing the bottom plate is best done when one worker nails while others steady the wall. The short 2x4s nailed to the rim joist prevent the bottom plate from sliding off the floor when the wall is raised.

to work together (see the photo above). Remind people to lift with their legs, not with their backs. In many areas, builders put a heavy bead of caulk or a roll of foam (polystyrene) on the floor or slab under the bottom plate before rais­ing a wall. This helps keep out cold air as well as any bugs that may want to migrate inside. To ensure that the wall won’t slip over the outside edge of the building as it’s being raised, nail pieces of 2x stock to the rim joist so they stick up a few inches above the floor to catch and hold the bottom plate (see the photo at right). On a slab, bolts hold the bottom plate in place.
