how to attach a 2x4 to concrete....

This would be easy to do, if it was to go down on the wide side. But I need to attach it on the 2in side.

Any suggestions?
Thanks

What's the end goal here?

Concrete block, slab, poured wall, ...?

What is the purpose of this 2x4? Some L brackets tapconed to the concrete might work.

You could use a solvent based construction adhesive like Liquid Nails.

to idea behind this is to level a subfloor in my basement.
The concrete slab has a slope in it. I plan to lay the 2x4 on the narrow side against the slab, and cut it with an angle (the top part of it) to make a horizontal plane to lay down the ply.

Can't really glue it, since I am putting a insulation paper over the slab, to absorb the humidity.

Just one 2x4 involved or several?

How damp is this basement?
Need a vapor barrier not paper.
Cut part of the joist needs to face down and they should be pressure treated.
I'd also be laying blue foam between the joist, 2" min.
Only thing I Tap Con is what amounts to the rim joist to the outside walls.
Once the subfloors attached to the joist and rim joist where's the joist going to go?

Attaching to Concrete

Attach a block to the concrete flat side down with a powder actuated nailer. Nail the joist to the edge of the block.
