Creating a triangular opening in an existisg loadbearing masonry wall

Creating a triangular opening in an existisg loadbearing masonry wall

(OP)
I have read some forums on this site on creating openings in existing loadbearing masonry walls using needling and "pinch beam" methods with channels.

I am trying to understand if these methods would be applicable in creating a triangular opening for a louvres in a masonry wall near the top of the wall of a two story building.  I am trying to maintain an existing cornice so the opening would need to shore a couple of feet of masonry above the trangular opening to allow removal of brick below.

I am leaning towards the pinch beam just not sure how this could work in a triangular configuration. Any thoughts or experineces out there, either way?

Make an oversized rectangular hole below the channels.  Then install a proper lintel for the opening you need. Finish by filling the opening as required with new or salvaged masonry.

RE: Creating a triangular opening in an existisg loadbearing masonry wall

Based on your sketch, the opening goes to the cornice...why do you need to support any of the facade?  If all you are supporting is a couple of feet of brick veneer, then a ledge angle attached to the structure would be sufficient.
