safe mounting of ceiling fan to concrete ceiling?

[dale rex]

Need to install a ceiling fan on a concrete ceiling for a relative of mine in her apartment. I 'm not sure what type of anchors would have the best pullout resistance to mount the fan securely. She wants a swag setup for the wire to be connected to a wall outlet. Would wiremold be a better choice? Is a box needed to mount the fan bracket to or can the bracket be mounted directly to the concrete?

Use WireMold;

When you say concrete I assume you mean flexicore. Scan the area you plan on drilling for metal. It may have pre-tension cables in it. You don't want to hit one of those.

If it is flexicore, there are hollows cast in the product. If you can locate in one of them, toggle bolts will work. TapCons, epoxy, caulk in anchors, expansion studs.........

not sure what it is yet, didnt look at it, just talked to her on the phone.. I will go look at it this week sometime to determine what it is. She told me that some other tenants also had fans mounted, and according to them the ceiling/floor was 1 foot thick solid concrete.

I would find that unusual. The weight would be......well

There will be rebar or tension cables in the slab.

If it is solid, a 1/4" Rawl anchor or Tapcon should work well.

I guess your talking about a concrete ceiling with popcorn on it ?

I'd get a deep octagon or square wire mold box and screw it to the ceiling with Tapcons. Add a bit of construction adhesive like PL 200 (not grip tite latex) after scraping to the concrete. New const ceiling boxes are rated to hold 55 lbs - and most fans are within this range before addl support becomes necessary. That's not to much for Tapcons. Be sure the wire mold box threaded holes line up to accept the long threaded screws that the canopy cup or bracket attach to.

Along the ceiling stay with the chain. Looks better than WM. Again use a sm tapcon with small plastic hold down loops (clear, white, black) - pulling the chain tight as you go.

And like Tom said - for the chain you can use rawl plugs or equal with some small screws.
