Concrete column reinforcing terminology
Concrete column reinforcing terminology
(OP)
Per ACI, in a concrete column all corner bars shall have lateral support. In addition, every alternate interior longitudinal bar and every bar more than 6" from laterally supported bar shall be laterally supported. (ACI 318-05 7.10.5.3).
For these interior bars (alternate or 6") I've always seen this lateral support provided by a tie with a 180 degree bend at one end and a 90 degree bend at the other.
In my last office - there was an older field inspector who insisted these cross ties were called dogs, but nobody in my current office has ever heard this. Has anybody else every heard this terminology before? Is there a more appropriate term for these cross ties?

Seriously - I've never heard the term in many years of specifying them. I call them "cross ties" but I suppose the dudes in the field might call them something else.

Thanks Cliff, based on all the previous posts I was worried I'd lost the bet with each of my coworkers. This was in the DC region.
My old coworker that taught me the term had a story that he loved to tell me every 6 months or so. He was on site with a young engineer and convinced the poor guy that the ties were actually called cats. The young engineer filed a field report indicating that all the cats and dogs were in accordance with contract documents, lol.

Maybe, instead of the field inspector they should call animal control for the next inspection.

I decree they be called LJ bars or JL bars, depending upon which way you place them.
