What adheres best to a basement wall made of LECA blocks?

[A-O]

I have a partition wall that needs to be attached to the house in this way



The angle we will weld together is to be screwed into the walls, but how?
Screwing directly into the Leca block with a lag bolt will not hold!
I was thinking of using an expansion screw where I drill and fasten the plug in the wall with glue,
remember I had to do that when I mounted a plasma TV on a brick wall. The plug just kept spinning around otherwise...

Would prefer to avoid through-bolting as nothing should be visible on the outside.

Tips would be appreciated!

Regards

I don't quite understand what it is you're supposed to hang on the wall or what it weighs, but Essve's lightweight concrete screw is a pretty good option for normally loaded fastenings. Secondly, I would consider a facade plug.

There are plugs and screws specifically designed for lättklinker. If you want to secure it extremely well, you can drill a couple of centimeters more than the plug and secure it with cast.

cast it in place on the other side you think? I'd prefer it not to be visible from the outside

Hilti Hit sits as firm as a rock but it requires a special applicator for it, but I think Essbe has some variant as well.

I used these, they hold extremely tight and are available in different sizes

...but neither the Capricorn anchor nor the Fischer plug is intended for LECA. The Fischer plug is for lightweight concrete, yes, but not for LECA according to Fischer.

I made a little mistake there...
When I screwed into aerated concrete, I used the fischer plug.
For Leca, I used the NL plug http://www.beijerbygg.se/store/privat/f%C3%A4stdon/inf%C3%A4stning---expander/expander-plast/n-plugg-nl8x65-001378020#.UYEpASvkW0E
and I have also used lightweight concrete anchors found in this pdf from weber, but I don't remember the brand of the "anchor." I think it wasn't even called an anchor, it was called a "type" screw plug. http://www.weber.se/uploads/media/leca_murverk_infastningar.pdf

Chemical anchor and threaded rod!

 

[MathiasS]

The fundamental question is probably what it is that the thread creator is supposed to fasten.....and what kind of load can be expected. Chemical anchors etc. are quite complicated compared to a lättklinkerskruv.

Doesn't TS mean that he should attach the two walls so they stay together? That's what I think it says in the post?

When I built the garage, which has one layer of leca under the sill, I used facade plugs from byggmax, they held really well in the lecablocks.

In Sweden, it was sold as Lecapluggen.....sits like a rock in Leca and hollow brick.....I installed door frames in my previous house with them...
