Squared U rebar; what is it?
Squared U rebar; what is it?
(OP)
A local expert has proposed building 'rails' atop an existing slab to support a big engine, said rails comprising a number of rebars bent into a squared U shape and epoxied into paired holes drilled in the slab, surrounded by epoxy grout poured into a plywood form.
He calls the formed rebars 'wickets'.
The shape and orientation does suggest croquet wickets, but I thought rebar formed like that was called 'stirrups'.
... but I know next to nothing about concrete.
So, what's the right word?

Sorry Mike...couldn't resist.
I'm not sure I see what he's trying to accomplish with this configuration. More often we would use an isolation frame, mounted to the slab with vibration isolators to reduce the amount of vibration transmitted to the slab. The proposed method seems to create a bunch of isolated load points with no vibration mitigation.

I've never seen a masonry contractor even come close to that kind of precision, but my limited experience is old; maybe they've gotten better, and it's not my problem.
... not until the bolts come out in the wrong place and they need a spacer frame with top and bottom holes precisely misaligned. BTDT.

RE: Squared U rebar; what is it?
You are exactly right...they'll screw that up. System needs to be simplified so that it has a chance of getting properly implemented.
RE: Squared U rebar; what is it?
It does seem there is precedent to use the term and system although this is in a different context than yours.

(BTW I didn't think Americans below the 49th would know what wickets were, although it's not spelt croquet, it's cricket)
RE: Squared U rebar; what is it?
In the UK croquet hoops are called hoops, in the US they are wickets.
I would expect that the drilling and epoxying method should give a fair chance of achieving accuracy. Certainly better than trying to cast in place with the slab.
But the overall system I don't understand without a drawing.
