Hilti anchor 1

[JPAULI167]

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?

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)

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

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

Call Hilti.

What are the loads experienced by the Hilti anchor?

 

[JStructsteel]

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.

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.

 

[JPAULI167]

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.

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

 

[Einsteim]

Agreed that Hilti website stinks.

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.

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.

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

 

[abusementpark]

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

 

[JStructsteel]

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

jrisebo:

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

 

[JStructsteel]

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