Ceiling – What’s this bracket

ceilingmounting

Has anyone seen this type of bracket before, or have suggestions on what it might be called? The drawing is upside down for the intended usage – basically I want the U-shaped piece on the underside of a joist, and the other piece on the top of a sheet of plywood. My goal is to slide if together to hold the plywood up.

Right now the whole idea is hypothetical – first I need to find the bracket to see what kind of load it could hold.
