timber loft joists in a stick framed house - 05/09/10 07:27 PM
So in my 30x26 stick framed house we are using 4x6 timber joists for the upper loft floor. they will be set 2' down on the 10' wall (creating a 2' kneewall). they also run the direction of the rafters and will aid with holding the house together.
I am trying to find the best way to attach them to the wall. I intentionally did not build them ontop of the wall and build another short wall ontop of them for fear of "hinging" the kneewall. I am thinking of running them long into the wall cavity and using either truss locks or bolts to attach them to each 2x6 stud. (the other end of the joists will be dropped into a summerbeam in the middle of the house) . I am just concerned that these 14' long joists will need more support than being bolted to the studs- am i overconcerned? Or do i need a ledger block? is it better to let the ledger into every stud or attach the ledger to the face of the stud?
Second- will a drop in soffit tenon on the 4x6 mortised into a 6x10 summer beam be sufficient? these joists will be in addition to the structural ridge beam, but no collar ties in the ideal spot (for design purposes). the entire house is a cathedral ceiling.
thanks
