Concrete Anchors

[zalaska]

Hello,
I will be mounting equipment racks on a raised floor (floor tile deck). What are the best anchors for doing this? The anchors will be drilled into the concrete. I will also be using all-thread to hold the rack down. Thanks...

You want to look for lag bolts. Drill hole in concrete and tap in lag bolt and then take bolt out and center rack over the predrilled holes and tighten down bolt into the the lag. Pretty easy to do. Good Luck...

You can find Redhead brand concrete wedge anchors at almost any local Home Depot. A size of 1/2" x 3-3/4" works well for relay racks.

See

for an example of the anchors that I'm talking about.

Thanks for both replies. I looked at your link to the anchors. They will not be long enough (the space between the concrete floor and the raised floor tile is atleat 12"). I did see the drop-in anchor on the website that would probably work though, but I will have to use all-thread and cut it to length. Think that would work?

I guess I'm confused. Are you trying to bolt your equipment to the concrete or somehow anchor it to the raised floor?

Bolting gear down to raised floor tiles won't buy you much in terms of stability. If this is a 4-poster box, then attaching earthquake strap and/or wire ladder should be plenty.

In POPs or Central Offices, two-post relay racks are sometimes suspended along horizontal rods so that they could actually swing if necessary.

Do you have any seismic requirements. If so I would recommend the raised floor rack installation kit from CPI. If not you can just use uni-strut spring bolts and all-thread.

Are you looking to bolt the Raised Floor to the Concrete then Bolt the Rack to the Floor? Are do you want to go from the Concrete up though the Floor to the Rack?

sorry I read wrong, yes I think the drop in anchors would work with threaded bolts cut to size. Here is an article I found on mouting a CISCO rack.
