Punching bag in lightweight concrete

[fredrik.johansson]

The daughter received a punching bag (22kg) for Christmas and now it needs to be hung in the basement ceiling. It is a Siporex lightweight concrete floor in a house from '76.
How should I best secure it to the ceiling?

I was thinking of using anchor adhesive.

Threaded rod and lashing point? https://www.biltema.se/bat/dacksutr...sten/surrningsfaste-rostfritt-8-mm-2000060242

Screw eye straight into the anchor adhesive? https://www.hornbach.se/p/skruvogla-habo-42a-elzink-m10x75mm/10653329/

Or is there another type of fastener I should use?
Expansion bolt?

I wouldn't have used a single anchor point but chosen a mount with more attachment points, at least two, preferably four.

In lightweight concrete, I would probably most prefer to secure it with a through-bolt rod, but if that is not possible, at least four anchors and sturdy lightweight concrete plugs, such as Fischer GB or Tox Ytox. There will be a very large load on the fastening when the bag swings around.

There are also options with a wall mount for a punching bag. The force is distributed more favorably in such a setup - not directly in line with the screw and plug. There are also completely freestanding stands, but they cost somewhat more.

Thanks for the tips!
I found a smaller bracket at hornbach and mounted it with tox ytox plugs. I tested it with my own 85 kg and it seems to hold well.
Knowing this family, there won't be a rush to punch the bag... but if there is, I might have to upgrade the bracket to something sturdier as bicep circumference grows.
The ytox plugs were totally different from the plugs I've used before, which were also supposed to work with lightweight concrete (mostly tox triwing).

I interpreted the headline as if the punching bag was made of lightweight concrete... Which piqued my interest

If you thought Ytox was brutal, you should see Fischer GB. They have rotated plastic wings that screw into aerated concrete.

The problem with a punching bag in aerated concrete is not the static load; it's that it swings and constantly wobbles at the attachment point. Aerated concrete is sensitive to this. Hopefully, it holds for you; otherwise, you'll have to try something else next time.

Probably, this bag will mostly have a static load... I bought it second-hand for a pittance after one of the daughters mentioned it would be fun to try.
But we'll see if it gets more frequent use; then maybe chemical anchors and a larger mounting will be needed.
