How to install this window sill bracket?

[Trunk]

Hello, today's stupid question comes here...

After a shopping trip with my partner, we came home with a bunch of these to put up the windowsills in the newly renovated part of the house. The problem is, I have no idea how to attach them to the wall.

I tried drilling a small hole and screwing it in, but it didn't go well, so I made the hole slightly larger and inserted one of those expanding plastic plugs, but that didn't work either. As soon as it’s loaded, it starts to wobble and sits generally loose. The wall consists of gypsum and some wood-like board (not chipboard).

I'm wondering if you have to screw it into some kind of stud or something, but that seems a bit strange if that's the case, and my partner says it shouldn't be necessary (but she has no idea how to do it either).

Thanks

The upper screw should be screwed into something so that it holds. Probably best in a wooden stud. In my case, it looks like they are attached to the window frame. Then the windowsill is adjusted to be "level" using the lower screw.

The upper screw should be screwed into something, so it secures. Probably best in a wooden stud. Then adjust the windowsill "level" with the help of the lower screw.

Mm, that's what I thought at first but as soon as you put a weight on it, even if it's significantly less than the windowsill+flowers, it's like the hole becomes too large.

However, I've had hell with those wooden boards being too porous before so maybe that's the problem. For example, you can't even put drywall screws in them. It's an old house so you don't always know what materials and makeshift solutions are there.



But they should work in walls with drywall+chipboard?

One potential problem I see even with chipboard is that only a few mm of the threads will be in the chipboard even when the adjustment screw is completely unscrewed. But perhaps the threads don't affect how well it holds?

 

[HasseTeknik]

With me, it looks like they are sitting in the window frame.

Not sure that dowels are enough. The important thing is that the threads go into solid material.

That type of bracket is meant to be screwed into solid material such as concrete/leca/lightweight concrete with large plugs or a compact beam. You won't be able to make it hold for the weight of a flowerpot model, and if someone leans on it, it will surely come loose.

Then I wasn't completely wrong after all, thank you for the answers.

Went out today and got another type and now the window sills are in place

Bumping this up as I need help.

I had a similar console before our renovation and was thinking of buying new ones that look exactly like that.
I don't understand how to mount these.

Is this correct?
1) Drill a small hole in the wall for the upper screw
2) Screw it in (i.e., turn the whole console so it screws in - is that right?)
3) Screw the lower screw (does this go into the wall or how is it designed to work?)
4) Screw the windowsill onto the console

Is this correct?

Grateful for answers.

That's correct. You adjust the lower one so it gets good support against the wall. We used to have those before, but they tended to give way, perhaps mostly because of the wall. We've replaced them with regular angle brackets. Not as nice looking but stable.

1) Drill a small hole in the wall for the upper screw

It will be a large hole with a blue or green plug

Screw it in (i.e., turn the entire bracket so it screws in - right?

Yep

3) Screw the lower screw (does it go into the wall or how is it constructed to work

The lower one is adjusted so the plate rests against the wall by screwing the hexagon, and it should support so the board is level.

Creates a big hole with a blue or green plug

We have a wooden wall, 15 mm raw timber and tretex so we of course managed without plugs but as jonaserik pointed out they are certainly better suited for concrete and the like.

These consoles work well if you pull them into a rule under the window.

 

[bygghemma]

Thank you for the answers! Now I'm waiting to receive these and start drilling/screwing.
One more silly question (not a carpenter here directly), but how deep should you drill? How do you know that?

It will be drilled under the window in some wood material.

Grateful for answers!

The diameter of the rod itself (excluding threads).
