Embedding things into slab (D-rings, hooks, etc)

[Rustang]

Background: Demolition of my old garage starts this coming Monday (June 4) and we're finally adding onto the house and building a detached 24x20 garage.

Question: Has anybody put recessed rings (like trailer D-rings) into their slab while it was being poured up? Also, I will be putting in a square receiver to place a tubing bender into (~3"x3" square). Has anyone done this as well?

All of the shops I've been to have done this as an afterthought. The reason for the rings is to provide an anchor point to tie stuff down, compress suspensions, etc. Usually that means breaking out some pieces of the slab, inserting a piece of steel or whatever, and then patching with quikcrete. I'd like to do this before my slab is poured so I have something that is flush and does not require holes to be drilled, etc.

As for my slab, it's planned to be a 5 inch thick slab with a professionally applied epoxy coating applied to it.

Any ideas or suggestions welcome.

Thanks!

I would not use trailer rings. I would consider imbeding threaded tubes to take screw in eyes. Friend has a raised pad in his shop formed from 6" tall channel iron. He hooks on to the edge when he makes a pull. But most of the time it is in the way.

I would design the recessed area so they have a cover, I can see them getting in the way. A would use a small recessed steel box with thick cover. I would consider using a piece of rebar bent and welded to rebar in slab as a u hook, I couldn't see that ever breaking and you could hook on easily.

I've thought about something similar as an attachment point to bolt/hook up a winch to temporarily. My driveway has a bit of a decline to it, and I can't push anything up into the garage...would be nice to be able to winch into it! Or if nothing else just use a come-along and reset it every few feet.

When we poured the slab for our ranch shop about 40 years ago (I was 5 then) we put in about 3 in inverted U rings for att. points in 4 different locations in the shop. As I recall the legs of the U were made into Js, then recessed in small coffee cans so the tops are about flush to the floor, but there is still room around them to secure hooks or whatever to them. The area below them was dug down a bit more so there is a bit of a pier around them to provide more concrete to hold them securely. They have come in quite handy over the years for a variety of things, but they are not in the way. One disadvantage is that the recess around them can fill with water or debris and needs to be vaccuumed out occasionally. I like the cover idea for this reason. Just make it so the cover is flush to the slab.

Northern Tools sell pulling pots that are designed to be sunk into the concrete. These allow a chain to be hooked up to pull against. About 50 bucks each with covers.

I have seen eye bolts set into holes apx 8 inchs square and 6 inchs deep.
The bolts had 1 inch threads and big washers and nuts on the bottom to catch the concrete. I assume there was a hole under them to get the concrete deeper where they were. I don't think the slab was over 6 inchs thick.
The covers were just 1/4 inch plate with a bit of angle iron welded on the bottom to keep them from sliding around. They stuck up the 1/4 inch above the floor, but nobody seemed to care.
They slid a prybar under the edge to lift them up. If you make yours flush with the floor you will need some way to get a hold on them to lift them out.
Maybe a big magnet?
It seems to be the kind of thing you would rarely use, but it is real handy to have when the need comes.

I looked out on their website, didn't see anything like this... Any idea what there are called or what to look for eslewhere? If anybody has a link I would appreciate, I'm within a month or so of pouring a slab and this just strikes me as a great idea that would save lots of time later.

just wait until cures , drill holes where needed insert tthreaded rod or bolts with west system epoxy resin by gougon. if you ever need to relocate /remove the bolts , you heat them up w a torch and it degrades the epoxy, otherwise it has awesome grab strength!

Mdshore328 has a great point. You can install any item where you want using cannon bolts as well. They have a female threaded section that locks into the floor below grade and a male section that can be installed and removed as you see fit. Put a plug in the hole when not in use. change your mine about the location? Instal another one and fill the old hole or leave for future use. i have used cannon bolts on air structures and they hold well enough that we pulled up sections of slab when one air structure was over inflated during setup and the cabling was a bit too tight.

leveling and finishing concrete around stuff in the slab surface is a pain.

"don't need to replace a whole pot if you break a chain"

Hope I'm not there that day.

Vicegrip,

What's a "cannon bolt?"

Thanks,

Dave88LX I have the same problem except I have a very short steep driveway.

Thanks for the link SoLow, I will definitely be putting in one or two of these in.
