OSB hangerboard for stair stringer? - Contractor Talk
网页2006年3月6日 · WRONG. The 3/4 for the riser is assumed, Spencer said he built stairs before, so bypass the elementary stuff.

This assumes that the hanger board is not mounted flush in the …
Hanging stair stringers using new Simpson thingy
网页2010年10月18日 · I will not go out of my way to use any strap that I feel is not needed. I have built hundreds of steps and never used strapping like that. If your stringer is hanging by that little bit, either add blocking underneath or use a wider board where the stringer meets the deck. I agree with Fes that a stringer is a rafter.

网页2017年1月3日 · I would prefer a raised stair stringer instead of a dropped one. That way you could anchor your stair stringers to the wood joist frame instead of trying to hang it from that steel beam. Put in a couple 2x10 header joists, or whatever those are, add joist hangers to each stringer, the kind that pivots on the bottom, and you'll have your connection.
