I would have to agree with Derek here.
The book/frame Michael was referring to is actually talking about a modified version of the English tie joint/beam. Like I mentioned before the plate is not a continues plate but rather individual(intermediate?) members going from bend to bend. They are mortised into the post of each bend. But instead of the tenon being on the post and the mortise on the plate they reversed the assembly. So the post has the mortises and the plate the tenons. I wish I could add a picture but I cannot get my computer to do what I wish it to.
In any case he, Michael, did not mean a wall purlin or so when talking about the intermediate plate.
