I've begun to fix the open issues in my 1921 home. One of the 1st floor floor joists is split at the notch that was cut into one end. The split runs about 4 feet. I'll probably have someone either sister the bad area or possibly replace the entire 11' joist. In the meantime I thought I'd glue the crack, jack it into place and install a joist hanger.
The problem is that every joist has a small wedge removed right under the "tab" portion that plugs into the center beam. (Sorry about the terminology. I don't know what some things are called.)
Anyway, I was planning on using a Simpson LU28R-18 old work joist hanger on the 2x8 joist. Because of the wedge that's removed, there would only be about half an inch of the bottom of the joist that would actually sit on the hanger. One other potential problem would be that 2 of the joist nails happen to line up right at the split so only 4 of the 6 joist nails would give solid support to the joist. The 8 that will nail into the center wooden beam will be fine.
So my question is should I just go ahead and use the LU28R-18 and be happy that at least it has better support than it has had for the past who knows how many years (we've had the house for 2 years and it's always been this way), or is there a better way to improve the support?
Here are a few images. One shows the split joist. Number two shows an intact joist (that dark line near the top is discoloration, not a split), also showing the wedge cut out. Again all the joists have this removed. The third shows a quick drawing of how only about half an inch of the joist bracket would support the bottom of the joist (although the nails would also give some support).
Thanks for any assistance.
