Mount in ceiling with highest possible WAF

[Mathias Dahl]

Hello,

I am going to hang a pair of Roman rings from the ceiling at home. The rings will not hang there permanently, only when they are in use, so the installation should be as inconspicuous as possible, but at the same time durable and safe. Achieving the highest possible WAF (*) is of great importance

* Wife Acceptance Factor

The ceiling is concrete, standard for apartments from the 60s. I have already tested hanging the rings at a place where they are not supposed to hang, to test the sturdiness. My conclusion is that a sturdy screw per bracket/ring is sufficient. I drilled a 10 mm hole with a suitable plug and it holds tight! I'm considering a screw like this:



Ideally, I would like to install an internal thread in the ceiling, per ring, so that I can easily screw in and out a corresponding threaded bolt, but I haven't been able to find such a product. So I'm leaning towards drilling, plugging, and screwing in a sturdy hex-head screw that will stick out a few mm from the ceiling. It might be painted white for the highest possible aesthetic appeal.

The question is how to best attach the rings, or rather the straps that hold the rings, to the screw head. If it's possible to buy something that's not too expensive and holds up, that is preferred, but I can also consider making something myself. My main idea right now is to cut, drill, or file out a slot from a sturdy angle iron that allows me to slide the iron under the screw head. Like this:



The rings can be attached in the side holes with a carabiner.

I also thought that maybe you can mod an existing bracket, such as a lashing bracket, and create a similar slot:



Of course, this affects the sturdiness quite a bit, but if there's enough material, it should hold.

Another option is to figure out a way to attach a steel wire that I can then hang the straps for the rings on. The problem is that it must be a solution that is secure but can also be mounted and dismantled easily and quickly.

So to summarize:

- Safe and durable
- High WAF
- Easy and quick attachment/removal of the bracket once the screws are in the ceiling (preferably without tools)

More ideas?

Thanks!

Is it possible to instead of your idea mount two hooks/loops and use a carabiner to attach the rings? It feels both safer and more convenient while the visual impact isn't that much greater. Especially if you paint the hooks in the ceiling color.

 

[prototypen]

There is the obvious solution.

But it might be too conspicuous.......

Expansion bolt and lifting eye.

Anchor bolt is what you're looking for if you want a thread in the ceiling.

It's possible, but it reduces WAF I have it like that in the place in the apartment where I tested, but it's a bit too cramped to work well with rings.

Thank you! The term has been googled, I know, but it hasn't come up as a contender for some reason. I'll take a look again...

Expansion bolt and lifting eye.

Thanks! Then there will be a visible eye in the ceiling, right?

I also recommend using expansion anchors. Use dimension M12 and screw in lifting eye bolts there when the rings are to be used.

A point of observation is that the rings, especially with children playing, can create a rotational load which could cause the lifting eye bolts to unscrew.

Edit: M10 should suffice without any problem. Essve's variant can handle 450 kg tensile load in uncracked concrete.

I also advocate for using expansion anchors. Use dimension M12 and screw in lifting eyes there when the rings are to be used.

One thing to note is that the rings, especially when children play with them, can create a rotational load which could cause the lifting eyes to unscrew.

Good observation, thanks! A variant that solves this is to attach some kind of rail/bar/rod that goes between both ceiling mounts. In this... contraption, the two eyes are then attached.

I checked out the expansion anchors again and they actually look promising. Perhaps I dismissed that option because special tools are required and I hate buying (expensive) special tools that I use only once. But it wasn't so expensive I see now, and the question is whether you can't tap with anything that has the right dimension...

 

[Johan Lindell]

There are concrete screws that work without a plug. However, you need to "tap" and screw them in.

Hello,

I'm going to hang a pair of gymnastic rings from the ceiling at home. The rings won't always hang there, only when they're in use, so the installation should be as invisible as possible, but at the same time durable and safe. It's very important to achieve a high WAF (*).

The ceiling is made of concrete, standard for apartments from the 60s. I have already tested hanging the rings in a place where they won't be permanently, to test the sturdiness. My conclusion is that one strong screw per mount/ring is sufficient. I drilled a 10 mm hole with a suitable plug and it's rock solid! I'm thinking of a screw like this:

Ideally, I would like to install an internal thread in the ceiling, per ring, so that I can easily screw in and out a corresponding threaded bolt, but I haven't been able to find such a product. So, it leans toward me drilling, plugging, and screwing in a sturdy screw with a hex head that will stick out a couple of mm from the ceiling. Possibly paint it white for maximum aesthetics.

The question is how to then attach the rings, or rather the straps that the rings hang in, to the screw head in the best way. If it's possible to buy something not too expensive, and that holds, that would be preferable, but I can also consider making something myself. My main idea right now is to cut, drill, or file out a slot from a solid angle iron that allows me to slide the iron under the screw head. Type of:

In the holes on the sides, attach the rings with a carabiner.

I also thought that maybe one could mod an existing mount, for example, a strapping mount, and create a similar slot:

Of course, this affects the sturdiness quite a bit, but if there's enough material, it should hold.

Another option is to come up with a way to add a steel wire that I can then hang the straps for the rings on. The problem is that it must be a solution that is safe but at the same time can be assembled and disassembled easily and quickly.

So to summarize:

- Safe and durable
- High WAF
- Easy and quick attachment/detachment of the mount once the screws are in the ceiling (preferably without tools)

Any more ideas?

Thanks!

The picture with the red lifting eyes, slide one in from each side and ensure that the flat part with the hole slides in towards each other (rotate them 90 degrees) then they lock each other when you attach a bolt or a carabiner and all you need are the white-painted screws in the ceiling.

 

[mr.Ola]

Or insert one from each side and press them together so that they fit in the same way.

 

[Daniel 109]

Yes, only the loop will be visible. I did that to set up a swing in a room.

The image with the red lift ears, slide one in from each side and make sure the flat part with the hole slides towards each other (turn them 90 degrees), then they lock each other when you insert a bolt or a carabiner, and all you need are the white-painted screws in the ceiling

Brilliant! :-D

And for those who don't get it as quickly as I do:



There will be a serious talk with the wife tomorrow
