Interior CMU partition foundation
Interior CMU partition foundation
(OP)
We typically specify thickened slab and dowelled rabar for interior CMU partition walls. We don't use a lot of CMU so it was never a big deal. Now we have an elementary school that is chock full of them. Has anyone ever used some type of post-installed shear connector that can be easily fastened (screwed) to our 5" slab?
Seems like this would be tons easier on everybody.

It would be cheaper and quicker to epoxy the dowels 4" into the slab.

I would agree with Mike though that epoxy anchoring the dowels would be better and easier for the contractor if you didn't want to use embedded dowels. I could see it being a nightmare trying to accurately locate and hold in place mechanical anchors in the slab during concrete placement.

I do not believe tw was referring to wet setting the anchor.
The anchor I was referring to still has to have a pre-drilled hole, and was made by "Red Head". It is termed a "non-Drill Anchor" and is covered in an ICBO report #1372 dated Feb, 1975. You can probably get the current, updated report online if they still make them.

I would still put minimum reinforcing in the partition wall and tie it to the slab, but I am in a high seismic area too.

I've never done it this way & that is really my question: Has anyone done it that way?

Option I will likely use is to use some type of non-drill anchorage that will provide the connection & work with just the 5" slab.
thanks for the input

Dur-O-Wal makes an interesting anchor, Dur-O-Wal DA8800 OCM Anchor. I've never specified it myself but it may be OK for interior walls. I would definitely use some sort of dowel instead of leaving them out. I would also provide a footing, even if only 8x16.

You're right - a mechanical anchor could be set in drilled holes. For me though, if they're already drilling the hole why not just put the epoxy in there.
