I have a partial kitchen wall I'm trying to tear down. I took out the ceiling drywall and there are long joists running perpendicular to the wall which made me think the wall might be weight-bearing.
The partial wall does not have a double top plate, but the weirdest thing is that the joists are made up of two by threes on the top and bottom with a long thin sheet of plywood between the two, sort of like a long wooden I beam.
The first picture shows what the interspace of the joist looks like. The second picture shows how the rest of the room requires no supporting beams. The third picture is a close-up of the plywood between the 2x3s seeming to act like some kind of wooden I-beam.
These plywood joists don't end above the kitchen wall like a normal joist would on a weight bearing wall, and the rest of the room is completely open with no supporting walls.
Do you think I can knock this wall down? And not have the place collapse?
