Fixing workbenches to breezeblock wall?
MikeCapon - 1/2/12 at 07:15 AM

As above I have two 5 metre long benches made from 30x30x2 box section which I need to fix securely to a breezeblock wall. The building is pretty recnet so the blocks are fairly thin walled (<20mm) which makes fixing tricky.

I don't really want to use chemically fixed studs, particularly as one bench is fixed to two walls at right angles. Using studs will not be possible in this case.

Any offers of advice most gratefully recieved...

Thanks,

Mike

Spreading plates - metal - or wooden rails eg 3x2s - on the other side of the wall bolted through will probably be the strongest way.

how about thickness near the ends of the blocks?

Maybe masonary screws??

But I would be inclined to fix wood to the wall first, then get the bench fixed to that where you want to.


Surely this is a common issue in France? they seem to build out of flowerpot blocks?

Thanks for that idea Steve. Sadly the other sides of the walls are either impossible to get at (steel cladding on the outside) or walls that I really don't have the right to drill holes in (neighbour's workshop!).

Can you get female threaded inserts for chemical fixings?

Thanks cliftyhanger. Good idea to aim at the joints. I'll likely give that a go if I cant find anything else.

The concrete screws are probably excellent if you've got concrete to go in to. In my case all I have is the thin wall of the breezeblocks.

I'm going to look and see if I can't find a female threaded chemical fixing..

I'd go for the max overkill approach.

Chemical stud bond a nice big bit of 2*1 along the wall (including the return) using quite a few fixing points to spread to load and then mount the workbench to that with some big old screws.

Anchor-bolts or resin-boltd to the floor, then the wall fixingd are not to critical so a batten with resin-bolts, then screw to that.

+1 for load spreading plate of (ply?) wood (very Locost ) with multiple small fixings to the wall.
Then fix bench to that.

Floor Bolts are good too, as long as the legs of the bench are substantial as well.

Either that or just a tube of No-Nails! That will fix anything

Weld on some decent sized foot plates and bolt to the floor wood be my thoughts - avoid the wall issue altogether.

Are they Breeze blocks or concrete blocks ? If they are concrete blocks you will be fine to anchor to them by any normal method. Breeze is a lot less common than concrete as it is expensive.

Hi Mike

A basic rule of workshops is that you should never fasten a bench to a wall, any decent bench should be heavy enough to support itself.

If you must, a few brackets with decent sized screws are enough.

As others have said, fix the legs to the floor with Rawlbolts. Triangulate the legs if needed to give maximum stiffness.

Thank you all for your input. Got the job done by using 8mm studs chemically bonded onto the walls. The one stud at a right angle that would have rendered the bench impossible to remove was fitted using an open slot thus enabling me to slide the bench in and out of place as I need to.

Nice bench though. 10 metres long should be enough even for me...

10 metres isn't a bench, its a PIER !!

Just enough to really have room to work.

Pics coming... I promise.
