#2 concrete anchors

#2 concrete anchors

RE: #2 concrete anchors

MacGruber22,
I'm not sure what they are referring to exactly - my first impression would be that it is a wire size (#2 gage?) or a reference to a smaller bar than a #3.

You are right that the H&B site doesn't show anything required to meet their reported load capacities. I didn't find the specific 580 online - did see the 340 -
Is there an engineer-of-record you can contact and ask?

RE: #2 concrete anchors

At one time there was a #2 rebar. They were smooth (no deformations), 1/4" diameter. Used them on a small project in the late 1970's; they may have already been obsolete at that time.

RE: #2 concrete anchors

My limited online search did not find anything either, however the "HW580" refers to 5/8" dia askew bolts series which have been replaced by "HW340" series of 3/4" bolt inserts, that JAE referred.

Quote (The Steel Supply Co)

For many years the standard wedge insert used a 5/8" diameter bolt. This eventually declined with the development of the 3/4" Wedge Insert which is now the standard. 5/8 Wedge Inserts are no longer specified in new construction.

However, for any renovation work, if 5/8" Wedge Inserts are already installed in the concrete having the correct bolt can save significant time.

So this must be an outdated reference and/or existing detail of as-built condition, so maybe #2 is 1/4" dia rebar as SRE referred.

RE: #2 concrete anchors

#2 rebar is still common in the developing world. I even have a memory of deformed #2 on one project? That might not be right.

RE: #2 concrete anchors

(OP)
No one associated with this detail seems to remember what they were - nice. I found the cut sheet for the old 580. No anchor was required to develop the insert. Since it appears not have been integral to the insert, then there is missing information to describe the bend and length of rod required.

Fair to conclude 'belt and suspenders' is the reasoning for those "anchors".
