how to fix bottom plate to floor? (small stud frame)

[johnhenstock83]

hi all,

 

I'm working on a downstairs toilet, nothing fancy. I've got a few pipes that I need to cover, so I'm building a stud frame. I will need to extend it to cover the concealed cistern too.

 

what's the best way to fix it to the floor? I've got some damp proof course roll, intending to lay that first, but there's no damp or anything on the floor, it's mainly preventive.

 

do I just stick everything with CT1 or should I drill some holes and use some plugs/screws?

 

thanks

Have you seen concrete screws? They go through the timbers and straight into the concrete floor. 
 

Drill with a 6mm sds pilot, clear the hole a good few times to remove debris. Drill at least 3/4 of an inch deeper than you need.

I have reverted to using hit-fix for this. The hole doesn't need to be so accurate. The same applies though...predrill the timber, then change bit and go into the floor, deeper than you need and you don't have to worry about dust. Then thump and it is done, but tighten if it will take it.

Lovely solution, thanks. I take it there’s no need to use plugs in this case, right?
