Hang heavy weight on dry lined wall

Firefly2

My daughter has asked me to hang a large punch bag on a wall in her house. The problem is that the bag is about 20kg+ and the wall is dry lined. The gap between the plasterboard and the concrete wall is very large, about 75mm. The bracket has 3 holes for fixings and I can only catch a stud with one fixing. I really need to catch the concrete wall in some way but with the 75mm gap I do not know how to do this. Any ideas?

I had to do similar to hang my curtains, last owner had them hanging off the dry lining and they where all ripped out.

Get 100mm or longer masonry screws/bolts and hang it off the wall. Don't forget to pick up a masonry bit big enough to drill the holes, it's a pain having to drive back to the hardware shop to get one.

Get large frame fixings, would hold up a static load. Chadwicks have them fairly cheap, woodies / b&q can be very dear...

The problem might be from movement, I'm guessing they aren't just going to look at it. I wouldn't be compessing the plaster board as it won't last too long..

The simplest job might be to cut out the plaster board between 2 studs and the height of the bracket and replace with some 1/2" ply, then screw bracket to the ply.

Even simpler again would be to fix ply to the wall, a nice wide bit so it can be screwed into 2 studs, then just bolt the bracket to that. Bracket could be bolted on before offering up the ply.

the best and only way in my opinion as a dryliner is to cut square of plasterboard out fix bracket to block wall and patch back in , may take bit more effort but it WILL hold it

Are we talking about Rawlbolts etc? Any particular type?

But since it's a punch bag it may be a better idea to cut out a bigger hole and place something solid between the wall and plasterboard.

You are probably right, mine was for some fairly heavy curtains and rails only.
