Scissor joist
This home was built in 05. The back wall in the crawl space has a knee wall and then a sill for the joist. Does the sill need strapped to the knee wall top plate?
The joist sit on the sill and has one toe nail in it. How are they suppose to be secured?
Does the joist sitting on the top plate spanned between two studs need support under it. It is a two storey home?
I appreciate any quick replies because I have to get this off first thing in the morning. Thanks in advance.  |

Re: Scissor joist
Any chance the exterior sheathing is nailed off properly to tie everything together laterally?

Re: Scissor joist
I don't know the name of the sheathing but its those 4x8 panels that are about 1/8 thick. There water repellent. Don't remember what they are made of put are very flimsy. As far as being nailed correctly I doubt it but can't be sure.

Re: Scissor joist
I don't believe the joists need support directly beneath them, as there is a double top plate installed.
As far as nailing goes, I am unsure for trusess, but conventional framing is 3 8d nails toe nailed to the top plate.

Re: Scissor joist
There would not be any strapping here in my area. It has been about four years since I did any framing, but I know we wouldn't have back then. It may have changed. Then again, we're definately not in a hurricane zone, or even a high wind zone.

Re: Scissor joist
Would a single nail be sufficient for fastening?

Re: Scissor joist
You sould probably try and look up the manu. specs.
I'll bet they require one on each side of the flange, for a total of two.
