hanging a punch bag \ fixing

[souls]

Hi all,

I have a punch bag bracket and am clueless on how to fix it to the wall. The wall I want to fix it to it solid not plasterboard I think concrete or some kind of masonary (sorry of the lack of knowledge there) now comes the tricky bit on how to fix it to the wall, usually with wall moutable things I would use some masonary wall plugs and couple of screws and no problems. But as this bracket will be holding quite a heavy punch bag whats my best appraoch on hanging it securly?

Thanks for any help.

Cheers

forgot to add heres the bracket I have

You will need some expanding rawl bolts, the diameter is set by the size of the holes in the brackets, the length by the thickness of the wall, use the biggest that you can.

Best to first investigate what the wall is made of, if it is plastered over, you may need to expose the brickwork beneath, or the plaster will crumble and the unit get loose.

I'd use either resin+stud or rawlbolts, but I'd investigate the masonry first. I would hesitate to mount this to an aerated block wall, for example.

No hesitate about it - I definitely wouldn't mount on an aerated block wall. If I had to, I'd attach a couple of 4' horizontal timbers to the aerated wall and mount to the timbers.

Try sky hooks available from all good builders merchants, just go in and ask for a couple of free samples they will probably give you some.

Or put bolts right through the wall and make a sandwich of: bolt head, bracket, strong wood, wall, strong wood, washer, nut.

Obviously this does not work on party walls unless you're on /very/ good terms with the neighbour.

Hi,

The wall is solid, theres is no cavities I can see (after taping it) after having a look at it now. I'm not sure how to identify what the wall is made of, under the surface of the paint is a grey-ish colour, also not sure whether its relavant but its a flat I'm trying to put one up in. Having drilled a few holes before in this wall it was very hard to get through it. (apologies with the lack of knowledge here)

Also the rawl bolts sounds like what I looking for to mount the bracket. Would anyone be kind enough to point out what one looks like, would be much appreciated.

Also thanks for the replies and patience with this.

cheers

Yes and of course, failing these a long stand could be used successfully for this application! The tricky bit would obviously be securing said stand to the floor of course.

Screwfix call them shield anchors (rawlbolt is a trade name) see one here:

Much appreciated.

Right so before I make a pigs ear of this, basically I drill the length of this or maybe a little shorter put it in the wall and tighten it. Is any kind of wall plug needed or does it go straight in. Also been browsing on the screwfix site would using a resin with one of these make it more secure?

Another quick wonder how about using these

its a

7.5x80 Hex Head Multi Monti

The rawlbolt goes straight into a clean hole in the wall. Resin systems are used with very crumbly type stuff (typically) The hole is filled with resin and a stud pushed in and left to set. You wouldn't mix resin and rawlbolts. I haven't tried multimonti, but would guess that for high strength applications they would have to go into carefully sized and drilled holes in concrete.

I've managed to get the rawbolts and have everything ready to get cracking with it. Hopefully it'll hold the weight of the punch bag. I popped into my local timber merchant for some grip fill for some a room i'm fixing some skirting boards to and just saw them with many other fixings up on a display on the wall so I thought as things are going my way I got a few.

Thanks for all the helpful info mrcheerful and all, its much appreciated.

Make sure you drill the hole just silghtly longer than the full length of the bolt (if using ones where the bolt screws INTO the wall rather than the bolt (stud) being pulled out of the wall by a nut.

If your hole is too shallow, the bolt will bottom out, and as you keep tightening, the expanding body of the rawlbolt will be forced OUT of the wall and never actually get a purchase on the sides of the hole.

[souls]

Thanks for that Pete

I had to read that a few times to understand that, I think it's bene one of those days.

Appreciate that
