Hilti anchor

Hilti anchor

(OP)
Looking at anchoring a piece of equipment that weighs 6,000 lbs and has 8 support legs with 1/4" thick base plates.  What type of Hilti anchor is best for use on a 6" elevated concrete slab supported by 1-1/2" metal deck?   

RE: Hilti anchor

Are you looking at going with an epoxy anchor?  If so, you could use like a Hilti HIT RE-500, or HY-150.  Probably a 1/2" diameter with 4" embedment max (you are limited to 2/3d for embedment)
 

RE: Hilti anchor

The Kwik-Bolt 3 Expansion anchor is easy to install and you don't have to wait for epoxy set-up.   

RE: Hilti anchor

I agree with the Hilti Kwik-Bolt III.  Watch your embedment depth at the raised metal deck rib.

RE: Hilti anchor

Call Hilti.

RE: Hilti anchor

What are the loads experienced by the Hilti anchor?

RE: Hilti anchor

is this just for gravity loads, or hanging, etc? Hilti has load charts, etc that will help you pick out what you need.
Be carefull if its a hanging load, some epoxies are not for long term, etc.  

RE: Hilti anchor

I recommend getting your hands on the Concrete and Masonry Fasteners by Simpson.  I've found their catalog a lot easier to use over Hilt's.  In particular, I would recommend using the Titen HD by Simpson.

RE: Hilti anchor

(OP)
the loads are gravity only and not hanging, holes in the base plates are 13/16" diameter so a 3/4" diameter anchor would seem appropriate except that Hilti has a minimum base material thickness listed in their catalog.  With the 1-1/2" metal deck the minimum floor slab thickness would be 4-1/2".  Most of the epoxy anchors require more slab thickness so the Kwik Bolt 3 does look like the best option.

RE: Hilti anchor

Agree with abusementpark. Simpson's catlog is much easier to use than Hilti's and the Titen HD type anchors (essentially large diameter screw anchors ) are gaining acceptance and replacing expansion anchors in our area of the country now that they have gotten the required ICC testing and approvals in regards to ACI Appendix D  

RE: Hilti anchor

Agreed that Hilti website stinks.

RE: Hilti anchor

We often use the Powers Wedge-Bolt.  This is basically a large diameter tapcon that comes in 3/4" diameters.  We prefer the concrete screws over expansion bolts since they typically have higher connection strengths and work much better in vibration / seismic applications.

RE: Hilti anchor

So you are not concern with seismic for this equipment anchorage? If you are, go with Hilti-KB-TZ. The KB-III does not have the approved ICC report for concrete use for the new ACI code. Here in California, we always use KB-TZ for concrete, KB-III is strictly a masonry anchor now.

Another option is the Simpson Titen HD anchor. It's a concrete screw anchor so installation is supposed to be easier.

Like other people have mentioned, call Hilti and Simpson and they will tell you all about those.

RE: Hilti anchor

Hilti has a software program out right now for their anchoring products. Takes some getting used to, but could be worthwhile.  

RE: Hilti anchor

Simpson also has a free anchorage program that is supposedly in accordance with ACI Appendix D.   

RE: Hilti anchor

Einstein, I have to ask, who are you agreeing with?

RE: Hilti anchor

jrisebo:

Everyone that thinks navigating the Hilti website, and more particularly, finding the load ratings, is a pain.

RE: Hilti anchor

Oh, ok. I just didnt get that out of this post.
