|I need to remove some 12'x12' roll-up doors in 6" concrete tilt-up panels and infill with CMU. |
The current idea is to leave the steel frame, weld A706 dowels at the sides and epoxy dowels at the bottom. Then use bond beam units, drop in horizontal #4 bars and grout. That would take care of the sides and bottom.
I need an Idea for tying the infill to the steel door frame at the top. Suggestions?
