Are embedding anchors enough?

[robin_nerf]

I have previously installed a bar in the bedroom ceiling to hang with my back on, using expansion bolts, M10x90, it was SECURELY fastened, but what I now wish to install (attached image) in the concrete ceiling in the living room needs to be a bit more aesthetic, I want to be able to disassemble the mount without leaving a threaded rod in the ceiling as with expansion bolts (where it would have to be angle ground flat), I have seen the alternative "drop-in anchor" but don't know if it's equally strong? It needs to support my body weight (80kg) in motion.

Surely anchor bolts are enough!

I would have used Hilti concrete screws, they are quick to install, strong, and easy to dismantle the day you want to.

I've previously installed a bar in the bedroom ceiling to hang my back from, using expansion bolts, M10x90, it held VERY securely, but the thing I now wish to install (attached image) in the concrete ceiling of the living room needs to be a bit more aesthetic. I want to be able to dismantle the mount without a threaded rod remaining in the ceiling as it would with expansion bolts (where it would then have to be cut flush with an angle grinder). I've seen the alternative "drop-in anchors" but don't know if it's equally sturdy? It needs to support my body weight (80kg) in motion.

Looks more like a mount for an adult swing😬😀

That's correct (Almost)

Sure, hammer anchors are enough!

I would have used Hilti concrete screws; they are quick to install, strong, and easy to remove the day you want to.

I have no need for it to go quickly, the hammer anchors (4 in total) take as long as they take as long as it holds well enough in the ceiling for a man's body

Expansion anchors, at least Essves require special tools, Hillti's concrete screws do not.

It only costs a hundred for such a driver, so no financial crisis

Hillti's concrete screw costs a couple of thousand per package, maybe that's too expensive for you?

Essve's or Hilti's wedge anchors (Hilti has been around for 50 years, I think) are drilled in so the entire sleeve goes in plus 5 mm, and then a tool designed for it is used as mentioned. You can use any tool that fits into the sleeve to drive in the wedge at the bottom. It may also be possible to first drive in the wedge and then insert a long bolt and tighten it. They sit incredibly firm and cannot be removed again. It doesn't matter since they are so deep.

Impact anchors, at least Essve's, require special tools, Hiltis' concrete screw does not.

Impact anchors only require a punch or something similar to drive out the bottom.
