Anchor cmu wall to precast double t

[karinmk]

Any suggested details for anchoring a 1 hour, 8" cmu wall to the flange of precast double tee roof? Non-bearing wall, running parallel to the T's. I'd like to use double slotted angles attached to the underside of the precast, but not sure how this works with the fire rating. Architect shows only 1" gap with backer rods, which is not sufficient for deflection.

I've seen using 8" leg angles on both sides of the wall, and not directly attached to the wall. The angles could be attached to the underside of the DT flanges with pre-drilled holes and concrete screw anchors - all spaced to resist the required lateral loads.
