Mounting handrail bracket

[drbodyjr]

Hello!
We have finished renovating the stairwell. The only thing left is to mount the handrail. I have already acquired a 3.5m long round (45mm diameter) handrail and a few (apparently not enough) hooks. I only bought 3, but for this length, 4 are recommended.
My problem is the wall's construction and durability. There is a 6mm thick renovation drywall under the wallpaper. The wall itself was some sort of OSB/plywood. I don’t know how thick and strong it is.
Do I need any special plug for mounting or is a drywall screw and plug enough? For mounting the bracket (which consists of one screw) on drywall, the seller recommends a special plug, but here regular screws are used...
How should I mount the handrail?
Sorry if the question is posted in the wrong forum, the admin can feel free to move it.

Try to examine what's behind more carefully. An expansion plug must be adapted to the thickness of both boards.
If there is a building plywood, regular tea screws without a plug should be sufficient.

Hej!
Vi blev färdig med renovering av trapphuset. Den enda sak som är kvar är att montera ledstång. Har redan skaffat en 3,5m lång rund (45mm diameter) ledstång och några (tydligen inte tillräckligt) krokar. Har köpt nämligen bara 3, men för längden rekommenderas 4 st.
Mitt problem är väggens konstruktion och hållbarhet. Det finns en 6mm tjock renoverings gipsskiva under tapeten. Väggen själv var någonslags obs/plywood. Vet inte hur tjock och stark denna är.
Behöver man någon speciell plugg för montering eller räcker det med gipsskruv och plugg? För montering av beslag (som består av en skruv) på gipsskiva rekommenderar säljaren en speciell plugg, men här används vanliga skruvar....
Hur ska jag .montera ledstången?
Beklagar om frågan ställs i fel forum, admin får gärna flytta den.

Kan ju bli en del belastning på ledstänger så försök att hitta reglar att skruva i. Om du inte gör det, ta reda på väggens tjocklek och köp rätt expanderplugg.

I have the original technical description from 1978. The house is a Myresjhus, the stairs were not renovated before us, they just wallpapered once, so the wall itself is in original condition...

Yes, then your total thickness is 15mm if you have a 9mm board and 6mm plaster. But as mentioned above, if possible, attach them to the frame and then with wood screws. Otherwise, use expanders that work for 15mm.

What does 2x9 building board mean? One on each side of the stud or are 2 placed on the same side?

One on each side is my interpretation since both the outer wall and the support wall have a 9mm board.

If it's noisy in the house, you can insulate the interior walls as they don't have any insulation.

Thank you for the recommendations!
I will then try to find the framework behind the wall. According to the description, there should be 7cm studs in the wall, so it should not be a problem to screw in the hooks' 6cm wide plates. The hooks that do not align with a stud will be attached with a 15mm anchor.

Yes, an expander that can handle a depth of 15mm, the width of the expander is less important

The studs are probably 45 wide and 70 deep. The above description is for load-bearing walls, is that what you're going to screw into?

 

[drbodyjr]

Other interior walls also have 70 regulations, am I misunderstanding? I'm not sure if this is actually a load-bearing wall...

The handrail should be mounted here on the marked wall.

Standard studs have a width of 45mm, then they have different depths of 70, 95, 125, 145mm, etc.
But a wood screw of 70mm can hold a large load. If you measure between two holes, what is the measurement from center to center?

 

[drbodyjr]

I will check it later in the evening.

If you can attach two of three screws in the rule, it will be rock solid. The third screw can be attached with a simpler drywall anchor.

it could be that they have used 1200 mm wall pieces from the outer wall and inwards then there is a stud in the middle of the 1200 mm piece
