Hi everyone. I'm building a floating desk for my PC which is 2.9 metres long and 600mm wide. The frame (made out of 63x38 CLS timber, with 3x2 planed timber on top which will be the desktop) will be fastened to 3 walls, 2 of which are breezeblock which have been dot and dabbed and plastered. My question is what are the best lug bolts and plugs to use to fasten the CLS to the breezeblock wall? Should I put said plugs in flush to the plasterboard and into the blocks or put them through the frame and then into the plasterboard and blocks? I was thinking about using the Fischer DuoPower 10x80, would this be alright?
Which lug bolts and plugs?

- Start date
Those look like what I need, thanks. Would the plug not be too long as I am fastening 38mm thick CLS to the wall and the screw would possibly only go roughly 40 odd mil (depending on the gap between the back of the plasterboard and the face of the wall) into the plug , or would I get away with it? I would have thought that I need a shorter plug but they only seem to do 100mm or 120mm.

That is one big mother of a PC.

I would just use concrete screws no plugs required.

Concrete screws in breezeblock, really? I would have thought the blocks would have been too soft for that. I'm no expert though. I see what you mean about floating, I just meant that there won't be any legs, and the frame will be painted white like the walls, so the floating desktop part will be more illusion based
Did you mean thermolite blocks? They are soft .Concrete screws in breezeblock, really? I would have thought the blocks would have been too soft for that. I'm no expert though.

I've just Googled Thermite, because I've never heard of them, and no I mean Breeze Block/Aggregate Block. My house was built in the 80's if that helps.
I think id go down the threaded bar, plate washers, nuts and resin route. I would even extend the threaded bar into atleast 300mm of the floating desk especially in the centre where the desk will flex the most.
That's sounds a bit too complicated for me, nice idea though.
I just called Corefix and they advised me not to use their fixings. Even if I use the 120mm screws there wouldn't be enough screw going into the plug (38mm CLS plus the (probably 20mm ish) void in the Dot and Dab, it would only leave about 68mm of thread going into the plug, which they didn't recommend. Oh well, looks like I'm back to M8/M10 lug bolts and beefy plugs !
I owe you an apology, it looks like your suggestion is going to be the strongest method. Cheers
If it’s supported on three walls, thin battens screwed every 400 mm would suffice, use Fischer nylon plugs and 50mm x5mm Spax wood screws plus the depth of the battens. Make sure the hole through the batten is only as wide as the screw is. Drill the block carefully to ensure it doesn’t end up wider than it should be for the plug.
