Ribbed structure

Hi there,

This question relates to the last question I posted entitled "Rotated triangular tesselation"

I am trying to create a ribbed structure or waffle structure for the triangular surface tessalation in the attached image. It would need a saw tooth profile at least in one direction so that each of the triangles is rotated to the correct angle. 

I have tried using a waffle script; this didn't work the waffle sections are curved and I need them to be segmented into flat lines so I can apply the triangular pieces. 

I have tried using a lofted diagrid, attached, but to no avail. I can't get the ribs to join together and form one rib each, they are still made up of all the lofted surfaces separately. Can't figure out how to get the surface pieces to rotate and form correctly. Ideally I would like to have something like the attached photo.
