All Threaded Rod 2ö Dia.

All Threaded Rod 2ö Dia.

All Threaded Rod 2ö Dia.

(OP)
I need to install 2" dia all threaded rod into existing concrete. Most of epoxy gel adhesive manufacturers' (Hilti, Five Star, ...) data sheets go max 1½" dia. I would appreciate any recommendations. Thank you, IV

RE: All Threaded Rod 2ö Dia.

Call the adhesive manufacturer. Sometimes they have additional testing and data that is not published.

RE: All Threaded Rod 2ö Dia.

Can you find info for no.16 rebar? Then just use the minimum of the tabulated value and the cross section capacity of the steel.

RE: All Threaded Rod 2ö Dia.

jike and csd72 have it right. A third option, but expensive, would be to perform field/load testing of a few anchors.

RE: All Threaded Rod 2ö Dia.

I think that Hilti will do a test if you use their products.

RE: All Threaded Rod 2ö Dia.

Five-Star Ggrout has some recommendations and a design procedure in their Handbook on Grouting and Concrete Repair.

RE: All Threaded Rod 2ö Dia.

(OP)
Thank you all for your recommendations. I have called Hilti & Five Star and they do not have any additional testing/data for bigger rods. I am leaning toward the idea of using (4)-1"Ø rods welded to embedded plate with hole at center for 2"Ø bolts. Regards,
IV
