I have a chance to build a 30'x50' garage. I am a new, small builder/remodeler with some framing experience (I have built several additions, small garages, and decks). I usually work by myself. The requirements for this garage are that there be NO interior walls and that the outside walls be 14' high. I'm planning on using 2x6 12' LSLs on an 18" concrete stem wall, which, with the sill and bottom and double top plates, should give me the required 14'. I'm planning on using 30' 16"x5 1/2 Trus-Joist I-joists with a 16" rim joist. I have at least two problems which, if I can't solve them, will mean I won't get the job.
ONE, how can I get the I-joists up on the top plates?? I can round up some help (manually) but I'm afraid of the swaying that may occur when lifting the I-joists. Any suggestions would be greatly appreciated!!! (I would rather NOT use a crane (expense!))
TWO, how do I tie the rafters to the I-joists or do I even tie them to the I-joists?? Normally, I would just nail the rafters to the ceiling joists at the top plate and cut off the roof protruding joist ends in the plane with the roof; however, Trus-Joist says that the I-joist CANNOT be slope-cut farther back than the distance of the top plate. One idea I had was to a 2x6 top plate and then put the rafters to the top plate as I normally would. I would then install rafter ties using 2x6 sawn lumber, lapped in the middle and tied to the rafters and slope cut at the ends. The lapped rafter ties would rest on the I-joists (on edge) and a plywood subloor could be nailed to them. Is this overkill?? Is it structurally valid???
HELP????!!!!!!!!!!!
