What is this?

maverickuk82 · 31-12-2008, 12:31 AM

Hi fellow AVers!

Not really up on my Thermalite/Breeze Block/Concrete, so need a bit of help, sharpish like!

Gonna hang nearly 60kg on the wall in the morning.

My walls are dot and dab, so have drilled a hole in the plasterboard to see what's behind it - I don't know what it is.

See attached photos.

Also, have photographed the attached fixings which I'm going to use.

Any help appreciated!

I dont know what your walls are made of, but i would be getting my @rse down to B&Q in the morning to get some more manly fixings

60kg on those! You rather than me matey

i've read about those. it hangs on 12 of those screws showed. is that bad...?

can i pick these, rigifix up at B&Q?

Personally i would go with the biggest nastiest fixings you can lay your hands on, better to be safe than sorry.

wingnut121 · 31-12-2008, 1:05 AM

they are small mate i am not even shure that will even go in the brick, get some 3 1/2" at least and thicker

Grangey. · 31-12-2008, 1:17 AM

i wouldnt trust that at all mate. go upgrade asap, the cost of some heavy duty fixings will be a ripple in comparison to the cost of the damage youl do to your wall and screen if you use them and it goes wrong...

John7 · 31-12-2008, 1:31 AM

They 'aint gonna work matey - they'll just pull out of that flakey concrete blockwork.

Also, with that gap between your plasterboard and wall, it's going to bend/crack the plasterbaord when you tighten down on it

maverickuk82 · 31-12-2008, 2:30 AM

i'm gonna cut the plasterboard out and screw directly to the concrete...

Oh, and those screws\plugs are the ones that come with the stand...

deansocial · 31-12-2008, 7:18 AM

3" 10s with brown plugs would be good enough to hold and screen up. so many people are paranoid about fitting screens.

I see it like this, if i can screw a kitchen unit up which is held with 4no 3" 10s then that unit which on its own weighs 30kg +- then it is filled with tins of beans etc and stays on the wall i'm sure 10 screws in a wall bracket will hold more than well enough.

and in concrete block you can get worse fixing if you drill right through the block as it can spelch a good amount of block off the back side

Paul Burton44 · 31-12-2008, 8:36 AM

Those are standard concrete blocks (breeze blocks). They are not a thermal block.

I would go with brown plugs and 3 inch 10's as suggested.
You are also right in going directly onto the block (cut the plaster board)

maverickuk82 · 02-01-2009, 5:15 PM

TA-DAAAA!!!!

I used 12x3" coachbolts with some heavy duty (gold coloured plugs), i reckon I can swing on it if I wanted!

Am going to chase all the wires back in behind the plasterboard once the tree has gone etc.

maverickuk82 · 02-01-2009, 5:16 PM

the shelve things that all the equipment is on is going in the corner after...

The difference being that the kitchen unit weight is spread over a much bigger area both size wise and pressure wise (i.e. surface area) compared to a wall mount which is much, much smaller in size with lots of surface area missing within the mount. This also means that a mount is likely to have more fixings per block. Also, a plasma/LCD mount may be a cantilever altering the stress massively when extended and moved etc.

I've ordered my Rigifix mounts from Mark Grant off here

6 Rigifix mounts (each tested to 105Kg!) delivered for less than £10... do you really want to bother cutting out plasterboard at these prices?

Do a search for 'Rigifix' and read all the posts like I did - you wont find a single post where the rigifix user wasnt happy! One guy hung off his mount after using them and he weighs over 20 stone and it didnt go anywhere LOL! The best thing too is, should you ever wish to move the mount, after pulling the Rigifix's out, all you will have to do is use some filler on 6 plasterboard holes!

This is what Ive used in the past going into brick... Something along these lines...
Faithfull Shield Anchor Loose Bolt M12*60, FAIFXLB1260 at D&M Tools

Not that particular size but you get the idea.

27neth · 02-01-2009, 9:55 PM

For kitchen units there is only 2 small hanging brackets around 75mmx40mm each. These hold a unit up 1000mm x720mm.

have to agree with paul, you'll be fine with the brown wall plugs, personally I think the 12 screws you have will be fine if you have the brown plugs.

CLICK THIS LINK to see why people should be worried - and this was "professionally" fitted

As d3m0n says

Rigifix for example are made for heavy items such as plasma's, installed on walls like yours - for less than £10, do you really want to gamble the cost of your panel.....

27neth · 03-01-2009, 1:28 AM

The link posted was a bracket fixed badly with cavity fixings? not 3" screws fixed to concrete blocks. You could fix a bracket on the wall with 2x 3" screws and hang your own weight off it..

John

maverickuk82 · 03-01-2009, 9:24 AM

anyways, I fitted the TV with similar fixings to those rigifix, however, i did cut the plasterboard away. it's very secure!

albriscoe · 03-01-2009, 11:24 AM

Surely people keep on asking these sort of questions and all it needs is a bit of common sense.

If you`re thinking "I hope this is good enough" then it probably won`t be and a couple of quid more on decent secure fixings will usually do the trick

Anyway glad you sorted it and its nice and secure

Point being, the guy believed it would be perfectly fine because a professional installed it - and although certain bolts 'should' be fine, for the sake of avoiding spending a few quid, if those bolts turned out not to be as good as they 'should' be, then there would be a broken tv with no one offering to pay for it

maverickuk82 - Pleased you played the 'extra safe/secure' card and have it fixed solid!

but they are not 3" screws and that is not a block wall. I could glue a bracket to a wall and hang my weight off it and fully trust it

alot of boilers are held on the wall with 10mm plugs and 8mm coach screws and the stay on the wall and weight a lot more than a screen and could cost you as much if not more to replace but people dont worry about that

MAD ANDY · 05-01-2009, 2:49 PM

Personally, for the sake of less than £10 for the Rigifix and delivery, I wouldn't even risk brown plugs. Each to their own, but if my £1,000 plasma fell off the wall on the basis that brown plugs 'should' have worked and "but they hold up my boiler?!" I would be gutted that I didnt spend £10!

craigoscott · 05-01-2009, 3:24 PM

very nice mate, only thing is, is that TV on a swing out mount? if not then either the TV or the cabinet underneath it is not level! :D
