45-rule on single gypsum

[Simon Hellsten]

What would you say is the best way to attach a 45-regel to single drywall that can handle a bit more load? Yes, of course with screws in the studs where they exist, but I will also need fastenings in between.
Molly plugs feel like they are too short to go through a 45regel + drywall?
I have found this variant but have no experience working with it, does anyone have an opinion?

In that case, the Molly anchor is placed in the drywall and the screw goes through the stud. You will likely need to replace the screw then.

How much should you load the beam with?
Are there standing wall studs under the drywall?

Exactly. I've worked a lot with Molly but never with these dimensions.

 

[Simon Hellsten]

How much load are you planning to put on the beam?
Are there standing wall studs under the drywall?

Yes, there are standing studs that I will use, of course. The load will be a drywall panel that will extend straight out from the wall with about 50 cm on center to the next support that will come from the ceiling. It's hard to describe in text, but I'm simply going to box in some pipes that run in the ceiling.

Glue with ordinary contact adhesive along the entire stud, and screw into the studs. It holds just as well as screws in the gypsum.

Glue with regular setting glue along the entire stud, and screw in the studs. It holds just as well as screws in the drywall.

Thanks! Yeah, you might be right about that.

If you use a single gypsum Molly but replace the screw with one for double gypsum, you get a slightly longer screw.

 

[Dan_Johansson]

Those will be expensive screws then..

Do you need to fasten between the studs? Gypsum boards in the ceiling hang on sparse paneling that is attached to roof trusses with cc1200. The sparse paneling is weaker than 45mm.

The Molly is then set in the plaster and the screw goes through the stud. You will likely need to change the screw in that case.

nice that someone was awake.

install kortlingar only?

 

[Tjrex]

Fischers duo series are really, really good. Tec would also be easy to install for you.
Attach the rule to the desired place in the rules you already have, drill straight through and thread through the plug and then pull the "string". Lastly, put in the screw of appropriate length/dimension.

Yes, there are standing studs that I will of course utilize. The load will be a drywall board that will go straight out from the wall with about cc50 to the next support that will come from the ceiling. It's hard to describe in text, but I will simply box in some pipes that go in the ceiling.

I think it's sufficient to attach to the wall studs/ceiling. If you're comfortable working with metal studs, it's easy to work with when boxing in pipes in the ceiling.

 

[Installation]

Use a 50/50 plate angle instead. If you're going to cover pipes, it's enough to attach to existing studs. Or are you planning to hang a tank in your construction?
