Hi. Quick and simple. Internal wall goes through my house and all joists are placed on this wall. All except one, which is shorter and has been placed on solid wall which makes what used to be old boiler or tank cabinet. It is also nailed to the beam that goes from the other side on the wall and is placed on internal wall, both joists overlap each other. I want to knock down old boiler cabinet cos I want more space. Is there a way of joining two floor joists together where only one rests on supporting wall, I mean some sort of steel C bracket or something or will I need to replace short beam with long one and place it on internal wall? There must be some kind of method to repair(joining) broken supportive beams, THX.
