Which anchor bolt to use?

[liam546]

I am looking to strengthen the ceiling joists in my loft space. Each joists is 6x2 and sits a wooden wall plate. I'm looking to secure an extra length of timber above the wall plate (I think called a ledger) and then fix joists hangers under the joists and into the newly installed timber which I need to fix to the brick

My question is what is the best method of fixing this timber to the gable end brick wall? I only plan to use the loft space for light storage.

I've had anchor bolts suggested where they expand when tightened however my bricks have 9 holes in each and they are old soft bricks which I'm worried will crack. The other option I've seen is using rods fixed in place with a resin and then the timber bolted onto these rods.

A chap called frank has already suggested this on the building forum but I wanted to get some more expert advice on this forum too.

Sounds like the existing are fine for light storage, many properties have much smaller 4X2 structure and are used for light loft storage.

My concern is that where the 4x2 sits on the wall plate there is around 50% knotched out of the joists so the actually depth of what actually sits on the wall plate is only 2inch if that

OP says 6x2?

Sorry Fox hole. I meant to put 4x2 in OP. They are 4x2 which is knotched onto wall plate.

You could add a 2x2 screwed and glued to the top of existing or to retain the level, sister the existing
