Client has a long room which we are going to fit out with fridge kit. Consists of 2 x 2kw way blow evaps. The crunch is that we are not allowed to penetrate the ceiling of the room as it is to be outside and uncovered. We normally use the pvc mushroom coach bolts but he's refused.
I really don't want to span the room with channel and supports from the side walls so considering it's a std 100mm injected foam coldroom panel what do you tricky types use instead
5.5x25tech screws with m6 penny washers through the unistrut will hold it!
Not to sure RB ,Can you pierce the inner layer?
If so I'd use stainless self tappers and stainless Mupro base's
How are you getting the pipework out of the room?
Cheers
Stu
all holes out the side wall only. inner skin can be pierced. I was thinking about the spring toggles
what are mupro bases??
Good to go so
Just be sure to use stainless self tappers or tech's and you'll have no problem's
Or that no more nails stuff is good I hear:D
Cheers

Tek screws, or put wall mount evap, or tell customer to provide fixings!
If they are wedge coolers then self tappers no bother, if box coolers then you will need spring bolts or unistrut spanning the ceiling, other wise some sagging will occur.
Allternatively use upright steel at the end of the room and use cantilever brackets to hang the cooler (1m brackets)
al
Canta lever frames through the side walls, pipes as well. Not rocket science
If its new build get some wood moulded in the roof panel for coach screws.
.
Try these.

good for plasterboard but when they expand they need 20mm of substance to prevent them dropping out

its a back plate up north
maybe strut on the internal wall and bolt some upside down cantilever arms at the top of the strut to suspend the unit from, simples!
Job starts on 3rd Jan in Leicester so we will see how simples it is :-)Quote:

Absolutely brilliant for blind fixing especially into thin sheet materials.
Using these you could fix whatever suspension channel or thread bars you want, wherever you want.
Check out the link for a description of what I mean!
Available from RS, Screwfix etc.

grizzly thats coz were engineers and we make do with what we have in our vans-i had to hang 2 daikin 71 cassettes in a petrol station and that had only a corrugated clad roof- i had to use pozi screws on a cable tray stand off bracket to hang m8 rod- this was 20yr ago- for 2 yr i never walked underneath them!!!
That's why Grizzly's on the big bucks(and showing his age ,us kid's don't use rivets):D
If it doesn't involve power tool's it's old hat.;)

Should have used mupro base's or back plates as they are known up norff.HAHAQuote:

Remember being on a site where we were hanging some Mastair ceiling units. (not spec'ed by us of course) Told it was a solid concrete ceiling so drilled in and ah it's a hollow concrete ceiling. As it was a g.ment base getting on/off site was a nightmare Ended up hanging them on 6mm spring toggles instead. Never went back and never wanted too!Quote:

I understand your dilemma IM all to well. (I am still on the tools my friend!)
Although I am no longer known as a "Engineer" now I am a "Service Technician!"
The only difference for me is I have a large shed full of "Options" from various previous jobs over the ages.
So yes as budgets get squeezed ever tighter even my once plentiful stock is getting depleted.
RB's is not a mickey mouse company and I suspect that his budget can stretch to a Nutsert kit and hand insertion tool.
Stufus.
I still have a large Yankee Screwdriver which I can still fall back on if the batteries fail!
Big Bucks! That's debatable. A regular income is nice though.
You will never earn a fortune as PAYE (pay as you earn) - re how we in the UK pay income tax. (For our non UK / Irish colleagues.) If you want that you have to be self employed.
However being self employed has it's problems especially in a recession.
But you know all that don't you my friend.
Happy New Year to you all.

If you use fixings that only penetrate the inner skin won't this cause the roof panel to de-laminate and sag?
He'll be long gone by the time that happens...Quote:

If the panel sags its because the panel vapour seal has been compromised and is saturated with water.
The chances of that happening from inside out is Zilch!
As the guys have stated if a self tapper is adequate then Nutserts are Guaranteed.
If in doubt spread the load with multiple fixings.
