Angled sheet metal in corner 45x45

[2hjul]

Hello I have installed horizontal 45x45 in my garage construction. And now I have researched a bit on how to make it more stable in the corners. Most recommend attaching an angled thin metal sheet. But where do you think it should be placed? I've heard both. Either directly on 45x45 or between OSB and plasterboard. What do you think? Pros and cons? Thank you in advance

I have always mounted it between OSB and drywall. If you screw the drywall so that the metal sheet is clamped, it creates a very stable corner.

Okay. That makes sense. Is it some kind of plaster sheet screw you need?

 

[tergo]

Okay. That sounds reasonable. Is there some kind of drywall screw I need?

it works with regular drywall screws for wood

You don't need to screw through the sheet metal to create tension. You can screw just outside the metal angle, which also avoids the risk of the drywall screw pulling on the metal and thus not providing a completely compact pressure between all three layers.

Okay, well then. Now I have a bit more to go on. Thanks for the answer.

I'm in the same situation, how did it go for you, did you screw straight through the metal or a bit to the side as you were advised?

I screwed a little to the side. Sometimes I missed and also screwed through the sheet metal and that worked too. But most of them I screwed just outside the sheet metal.

Ok, and did you set the angle between OSB and drywall?

 

[2hjul]

Ok, and you set the angle between OSB and gypsum?

Yup, I did. Fastened the sheet metal with some small screws.

I find it easiest/best to first glue the metal bracket to the OSB/chipboard/plywood with mounting adhesive, such as PL600. You can use scrap pieces of OSB/chipboard/plywood to cut strips 15-30cm wide that can be temporarily screwed up to press the metal bracket against the substrate while the adhesive dries. Once the adhesive has dried, the metal bracket is rock solid, and you can safely screw the drywall directly through the metal bracket without risking the formation of a gap between the metal bracket and the wood-based board. It also provides very strong corners that can withstand a lot of abuse without cracking.

Sure, it takes more time. But the free availability of time is exactly what allows us DIYers to "afford" extra fine solutions that the carpenters don't have time for.

I think it's easiest/best to first glue the metal angle against OSB/chipboard/plywood with assembly adhesive, like PL600. You can use scrap pieces of OSB/chipboard/plywood to cut to strips 15-30cm wide that can be temporarily screwed up to press the metal angle against the substrate while the glue dries. When the glue has dried, the metal angle is fixed as strong as a rock, and you can safely screw the drywall directly through the metal angle without risking a gap forming between the metal angle and the wood-based board. This also provides very strong corners that can withstand a lot of abuse without cracking.

Sure, it takes longer. But the free availability of time is precisely what allows us home builders to "afford" extra nice solutions that the carpenters don't have time for.

That sounds like a very good idea! Unfortunately, the free time is starting to run out, winter is coming
Another question, I assume and hope that you don't need to put these kinds of angles https://www.byggmax.se/t-profil-t-5...MI1qeArZKn7AIVCdiyCh03cwaqEAYYASABEgIuJfD_BwE at every board joint since I stagger the joints between plywood and drywall. But in practice, won't all the board joints where you have horizontal studs to screw into become weak if you don't place vertical blocking in between?

 

[Gabbe1]

As long as you overlap the joints between plywood and drywall, you will have strong walls even with a horizontal framework.

Perfect, that's what I wanted to hear.
