Sparse panel ceiling?!

[BjoLil]

I'm going to hang a fluorescent fixture for my aquarium, it weighs about 15kg.
I'm not really confident hanging it with molly plugs in the drywall.
I thought the furring strips were along the seams in the drywall ceiling, but they seem to run crosswise.
I've tapped and this seems to be correct, also used a stud finder and it shows the same.
As far as I know, they should run in both directions?
Is this common? Or am I completely off track?

Which floor are we talking about, or is it a single-story house?
Glesen usually sits across the rafters, glesen does not sit both ways.

Normally, the gypsum is mounted along the glesen yes!

 

[Tomture61]

Normally, the drywall is mounted along the stud frame, yes!

Depends on many things, for example, if it's drywall 1200 x 2400 mm with spackeldiken on the long sides, I prefer to place the short side on the stud frame. This is because the short sides cannot be reinforced with tape.

1 1/2 floors. Ground floor.
Yes, sorry. Written unclearly, I mean that the glesen are across, not in both directions.
I can faintly feel that it is in the joints, even if I know that a stud finder is not always reliable, I think it should give a signal...

Depends on many things, if it's for example plasterboards 1200 x 2400 mm with putty edges on the long sides, I prefer to place the short side on the studs.

Regardless of the putty edges, it becomes stronger across the studs.

Yes, sorry. Poorly written, I mean that the battens are set across, not in both directions.
I can slightly feel that it is in the seams, even though I know that a stud finder is not always reliable, I think it should give a signal...

I assume we're talking about the lower floor; the roof trusses in your house function as the load-bearing beams of the intermediate floor (probably), so the battens are set across these load-bearing beams.

Why would it become stronger?

 

[Tomture61]

Regardless of spackle trenches, it becomes stronger across the gless.

How do you avoid cracks in the spackle on the short sides of the drywall?

 

[RoBo]

How do you avoid cracks in the filler on the short sides of drywall?

The painter's job, they use tape there anyway and spread the filler. Previously, there weren't boards with a tapered short end. Crack formation is much smaller with this installation. I have extensive experience with both installations.

 

[Tomture61]

At my place, I'm the painter (amateur). Difficult to fill a strip without a putty trough (I personally think).

 

[Plupp 282191]

Depends on many things, for example if it's plasterboard 1200 x 2400 mm with feathered edges on the long sides, I prefer to set the short side on the studs. This is because the short sides cannot be reinforced with tape.

If you place the board lengthwise, the long side has support all the way, we usually screw loose noggings on the short joint, feels better that the board edge has support all around then of course it depends on the room itself which way is best.

 

[Tomture61]

If you place the board lengthwise, the long side has support all the way. For the short joint, we usually screw loose noggings, as it feels better for the edge of the board to have support all around

How do you make this economical? It sounds like a very time-consuming job to place noggings at every joint. If I, as an amateur, do this, it's in my free time (which can indeed be valuable time).

I don't understand the reasoning that it becomes stronger if you place boards lengthwise with the spacing. Gypsum boards are equally strong on all sides once taped and plastered.

 

[Plupp 282191]

It probably doesn't take that long to screw three loose kortlingar per sheet, I didn't say that the drywall sheet becomes stronger, but I only think that the joint between the sheets becomes stronger, since they have support behind them as much as possible instead of just being held together with joint compound.
