anchoring to ceiling

ponzutwo · Nov 20, 2023 11:53 am

So....no discrete way to ask this and I am after safe installation advice.

I want to install a sex swing. I need some anchor points in the ceiling.

However I am not sure how best to install these. I obviously dont want to just drill into the bottom chord of the roof trusses, but the type of advise i am getting elsewhere is exactly that. Most giving that advice arent home owners or have any trade back ground, so Im not feeling the advice is sound.

Can anyone point me to some materials, ideally some drawings of how one might either reinforce the trusses or attach multiple anchors to them without potentially degrading its ability to hold up my roof?

I think you will require engineering assessment.

It depends on the construction of your ceiling, type of material used, type of truss, size of bottom chord, the expected location and amount of concentrated load plus dynamic load plus safety factor.

This would have to be the funniest post ever in this forum!

I'm not sure whether to take you seriously or not, but on the assumption that you are being serious it's a really interesting question.

I wouldn't be relying on attaching anything to your bottom chord.

Assuming you want to be safe and have the ability to engage in some vigorous fun without the ceiling collapsing, my method will require some patching.

So I would add a couple of studs to each wall, and run an LVL or a similar type of beam between them. It sounds like a lot more work than it actually is. But at least fixing your swing into a structural beam should give you hours of stress free fun:-D

Serious post. and thanks for your idea. Though it defiantly sounds like a lot of work. Especially to a DIYer.

An idea I had was to perhaps attach a couple members between the bottom chords of two trusses using hangars or build some sort of strongback between them. The anchors would be attached to these rather than the the trusses directly which is figure would spread the load and not directly compromise the truss structure.

Th load across the 4 points would be in the vicinity of 70-100kg....wheres Bimguy when you need him?

that's probably the "correct" and safest way to go about it, though realistically probably overkill. People install these all the time in much more thoughtless ways without hurting homes or themselves. Im just looking for a way that make sense and Im comfortable with.

We were so busy breaking beds that it never occurred to me to even think about the ceiling.
I can’t help you with expert opinion about the ceiling but breaking beds? Yes that is my area of expertise.

maybe then you can just beef up one of your bottom chords with a piece of 90x45 and see how you go?

in anycase, you gents may be interested in a show on netflix called "how to build a sex room"

Despite how it sounds (trust me, i skipped over it many times), it is a legitimately wholesome show and the old grandmother that is the host is great. The material is obviously challenging to those who have very vanilla views or appetites, but if youre a curious adult, I highly recommend it.

Just bolt them on or glue and screw. Is there some sort of anchor that may go over the top and place the load on teh top of the chord rather than pulling on it from below (i dont know if that even matters?)

I would have just put a couple of 3m 90x45s on top of your bottom chords and attach the swing to them.
If your chords are at 600 mm, then your load will distribute between 10 chords on each side, which is roughly 10 kg per chord - close to nothing, really.

depends on how much downward force is involved Alex

he is telling 100-120 kg max

I would limit max load to 200 kg

and probably his chords are at 450 mm centers?

I'd 100% rather go over than not. 70kg is the upper limit of mrs. 100 is me. Its very unlikely Ill be getting in the swing, but never say never

This is why getting your BIM data right is so important Ponzutwo.

Wait.........I meant BMI data

haha indeed.

I should also get some fluid dynamics modeling done to make sure sufficient drainage exists i guess.

Correct. The last thing you need is a moist environment.
