Apologies if this is a duplicate.
I'm attempting to floor my loft space. It currently has 47mm x 75mm ceiling joists, not enough for a floor. I am going to add something like 47mm x 200mm along side each existing ceiling joist, resting on the existing brickwork.
I am not going to be sistering these together, the existing joists are old and already bowed. I may perhaps bracket them together in the centre span to avoid any more sag on the old joists. The old joists used to have vertical planks nailed to the rafters above to achieve this, but they have since degraded.
The problem I have is this: I have flush eaves, so the vertical space over the outer brick skin (at the eaves) is limited and certainly not enough to accommodate an 8 inch square joist end. Are there any specialist joist extension plates (steel) I can use to rest on the brickwork, or is it safe to cut a triangle off the end of the joist without affecting the shearing resistance?
The eventual goal is for it to be able to hold expected weight of a regular floor in the house, furniture and storage will be going up here.
