Rounded wood screw 4.0x20 mm does not fasten in untreated panel 22 mm.

One option could be to use screws and nuts to attach the pulleys to the panel. Drill a little into the plaster to make room for the nut so that the panel lies flush against the ceiling.

In any case, the panels must be attached to wood material, plaster will never withstand the forces that arise when wet laundry is winched up and hangs on the frame/ropes.

Panel? Is it a single panel board?
And how have you attached it to the plasterboard?

I think some pictures would be helpful.

So. You need to find out what there is to properly screw into upwards.


Ideally, it's like roof trusses or some kind of cast ceiling if it's an apartment.

The plasterboard is screwed onto battens attached to these.

The battens can't handle carrying any heavy loads.

I have a flat ceiling, so is it called a ceiling joist then? Anyway, I should then try drilling at 30 cm from the wall into the battens and hope there's a joist behind? And then there should be another joist at 90 cm from the wall? That is cc 60?

An alternative might be to use screws and nuts to attach the pulleys to the panel. Drill out a bit in the drywall to make room for the nut so that the panel lies flush against the ceiling.

Anyway, the panels must be attached to wooden material, drywall will never withstand the forces that arise when wet laundry is winched up and hangs in the frame or lines.

I was planning to attach the panel to wooden material. But the pulleys themselves will only be on the panel where there is drywall behind. Isn't it better to use some kind of expanding drywall anchor? That is, the screw goes first through the panel and then into the drywall anchor?

Alternatively, I might go with your suggestion. But then I would use machine screws with a countersunk head. Then I don't need to drill holes in the drywall.

My plan is to attach 22x195x1100 panels to the studs. I intend to use wood screws and fasten the panel at 3 points on each stud.

If you have ceiling studs with a 600mm center spacing, I suggest choosing longer wood than 1100 mm if you intend to mount it across the existing wood, at least 1200mm long so you can attach to two studs.

Personally, I would choose something thicker than 22mm to make it more stable. My suggestion is that you choose 45*70*1250mm long pieces and mount them on the board across the framework that supports the plaster.

If you have beams in the ceiling with a 600mm center distance, I suggest you choose longer timber than 1100 mm if you intend to mount it across the existing timber, at least 1200mm long so you can fasten it to two beams.

Personally, I would choose something thicker than 22mm to make it more stable, my suggestion is that you choose 45*70*1250mm long pieces and mount them on the plate across the framework that supports the drywall.

1100 mm goes over two beams. 1200 would go over three beams. Or am I misunderstanding you?

 

[fribygg]

1100 board mm cannot go over 600+600mm

 

[Karrock]

1100 mm covers two studs. 1200 would cover three studs. Or am I misunderstanding you?

No, you are right. 1100 covers two studs, 1200 covers three.

 

[fribygg]

1100 mm spans over two beams. 1200 would span over three beams. Or am I misunderstanding you?

No, it's me thinking slowly (and incorrectly).
I still suggest you choose 1250 mm long timber and attach it to two or three ceiling beams.

Thank you for the help!

Can I (in addition to attaching the panel to the studs) also attach it to the drywall? That is, where the pulleys are, I screw through the panel and up into the drywall, perhaps with expanding drywall anchors? Or is that a bad idea? The advantage would then be that the pulleys are secured really well AND the panel gets additional attachment points.

What you call a "panel" looks like a regular chipboard with white laminate (i.e., the kind used to build shelves, wardrobes, or cabinets). What is the material, a regular shelf board? It usually doesn't hold very well when screwed in with regular wood screws (check the kitchen cabinet hinges, for example, or the shelf boards in a wardrobe, which are more like smooth pegs held up by the volume in the hole rather than threads).

Panel boards are made of solid wood, which might be possible to screw into.

I think you might be able to attach your chipboard to the ceiling against the joists, but it's more doubtful to affix wood screws that should withstand tensile load in the board?

Since you seem to have healed under the plasterboard in the ceiling, you can have electrical conduits installed inside the plasterboard; in that case, be careful not to accidentally drill/screw into them.

This is the one I bought:
22X195 EXTERIOR PANEL Rough-sawn spruce
https://www.byggmax.se/22x195-ytterpanel-p08021195

Should be possible to screw into, right?

Regarding tensile load, I'm considering screwing through both the board and the drywall using expanding drywall anchors. Could that work?

 

[fribygg]

Shouldn't it be possible to screw in?

It should be perfectly possible to screw in. However, the board is quite thin and to be able to bear the load of a drying rack, you probably need something thicker. If you hang wet laundry, you risk the screw that is only 16mm in the board coming loose and the rack and laundry falling down.

Thanks. That's why I'm considering whether I can screw through both the board and the gypsum. Gypsum usually withstands quite a lot of load if you use expanding gypsum plugs. That's my experience, although I've only hung heavy items on the wall...

Thank you. That's why I'm considering if I can screw through both the board and the plaster. Plaster usually withstands quite a bit of load if you use expanding plaster plugs. That's my experience, but granted, I've only hung heavy items on the wall...

Even though the plaster doesn't add much to hold the screw, it will be much better with a fully threaded screw that goes through the entire board than the ones you have chosen now.
