2/2 V Grip Deck

[Jerehmy]

See the attached pdf. The concrete slab rests on a "2/2 V Grip Deck". V grip deck seems to be Inryco (

but I have no idea what the "2/2" means. Anyone have any idea about this nomenclature?

Thanks

Probably 2” of concrete over a 2” deep deck for a total composite slab thickness of 4”.

It says 4-1/2” concrete slab above the deck callout and section A-A shows as 4-1/2”. Any other ideas .

Flutes 2" wide top and bottom? Or 2" wide flutes with 2" depth?

My 1980 Inryco/Milnar catalogs make no mention of Vee deck.

Are you sure it's Inryco?

I'm not sure. The catalog in the link is from 1973 and has a "Type V" composite deck. That's all I could find. It's not a big deal as I can conservatively calculate the capacity, but it would have been great to be able to identify the deck. Thanks for you help.

Did you try to contact Vulcraft and ask them?

2/2 = 212 = Two Hundred Twelve.

So apparently theres 212 V-grip and 312 V-grip. I found it listed in some UL assemblies:

It may have been manufactured by the Bowman Metal Deck/Wheeling Corrugating out of Pitt. Reaching some dead ends. Sent a message to SDI since Bowman used to be a member.

Maybe 2”, 12 gage then...

My thoughts...

Do you have access to the basement?
Why do you need to determine the capacity?
Do you have any way to accurately measure the installed thickness?

SDI came through and sent me the Bowman catalog from 1985. I've attached it in case any future person who comes across this thread needs the same information. Also, based on a site visit, it looks like the contractor installed the 1-1/2" not the 212. Go figure.
