Install in triple plasterboard

[Tobbeman94]

Hello!

I want to install a coat rack in the hallway where I have triple drywall. It seems like I don't have much space behind the drywall, so I don't think I can use a molly plug for triple drywall.

I don't know much myself, so I'm asking the question here; What options do I have? How much weight can a "regular" drywall anchor support in a triple drywall wall?

A "regular" drywall anchor is probably just a molly or something similar. A regular plug probably can't withstand much in a drywall.

A "regular" drywall plug is just a molly or similar. A regular plug probably can't hold much in a drywall.

"Regular" plugs work quite well in triple drywall. That is, regular nylon plugs for concrete. Drill with a 7.5 regular twist drill for 8mm plugs. Don't hammer in the plug, press it in instead. The risk is that the drywall may disintegrate around the plug in the future due to vibration, moisture, overload, etc., and it might suddenly come loose. So I don't recommend it for a hat rack. Such racks can become very heavy during a party with many guests.

Attach a piece of plywood behind the hat rack with screws and mounting glue. Paint it in so it is hardly visible. It will support the hat rack.

Best regards, Findus

I would think a bit more about the wall construction. How is it actually built if there's no space behind the drywall? Is there a firewall between apartments or what's it about?

Anchors in drywall, as mentioned, are not a long-term solution.

Good question!

I have a few holes today and when I insert something into the hole, I can feel resistance depending on the angle. So it seems there is something behind approximately at the hole. Maybe wires or something similar?

Strangely enough, it's the same phenomenon in other nearby holes.

Any tips on how I can gain more insight into what I'm encountering? It's hard to see since the hole is "deep."

Does it concern a house or an apartment?
Is it concerning an exterior wall, an apartment partition wall, or another interior wall?
How old is the house?
Does it look like extra layers of plasterboard have been added at the door and window frames?

If there is a light switch or a power outlet on the wall, it might be possible to see more by removing it.

Modern apartment ( 2011 )
Not an exterior wall.

I have marked where I was planning to put up the shelf in red.
There is undeniably something in the space behind since there's a lot of room between the wall and the wardrobe.

Since it is so new, the board should have documents on how the walls are constructed. Since it is next to the bathroom, it could be a space for the stammarna. Triple drywall does sound unusual, in any case.

Given that it's so new, the board should have papers on how the walls are constructed. Since it's next to the bathroom, it might be a space for the shafts. Triple plasterboard sounds strange in any case.

Good tip, I'll check with them!

Pipe shafts are quite often placed in those kinds of constructions, so maybe that's what you'll find behind. In 3x gypsum, universal plugs hold pretty well, so the question is if that's sufficient, and then you avoid the risk of damaging something.

There are such anchors you push through the hole which have a spring in the part on the outside, you need a longer screw.
Unfortunately, I don't know the name.

There are those kinds of anchors you press through the hole that sit with a spring in the part on the outside, you need a longer screw.
I can't remember the name unfortunately.

Vipplugg is the word you are looking for.
