Load bearing joint into breezeblock

Turnsnip · 22 Aug 2017

How much load can a breeze block take with the correct fixings?

I want to attach some 3m steel steel box section running parallel, offset around 1m away from the wall, attached at each end (unsupported in the middle). Complete weight of assembly including brackets, bar and the load it's designed to carry would not exceed 100kg. The bar will span across a door way so there can be no risk of it falling off and landing on someone. Setting the ends of the bar into the side walls is a non starter as the walls are spaced too far apart.

Is it possible?

If it's got enough weight above it, a lot. But if they're 3.6n blocks they're probably like rice crisper cakes so you'd need some excellent fixings.
Personally I'd find another way, if it doesn't ruin the illusion, you could bolt full height vertical bars to the wall then bolt your contraption to them, you could even make it free standing if you bolted it to a flat plate. But that would only work if you weren't trying to make it look nice.

Cosmetic appeal doesn't matter at all but cost does, it's commercial premises. The top arms would be bolted into the second brick from the top, the lower arms at a 45 degree angle bolted in a metre below. I will try get measurements and draw up what I am planning tomorrow if I get a chance. Will be easier to visualise and see if it's going to work or not.

I don't understand what is going on, but blocks can take a lot of load.

However, if this is a commercial place and it's not just some cupboards or shelves, then you would need professional advice.

Nothing fancy. A small beam to use as a trolley track to lift up to max 30kg loads off the floor, pull it over a mezzanine floor and lower it. Convenience to get boxes off the floor that are too big to carry up and down a ladder.

The beam assembly it's self would be more than strong enough I just have no idea if the breeze blocks are up to holding a weight like that fastened into their sides.

It's not open to the public.

But there are still obligations under employment H&S regulations to ensure that the equipment is suitable
