Platform fell off wall

[Griffin]

I'd go with the shield anchor loose bolt.

I think with that style anchor the shield expands further along the length of the bolt, which spreads the load over more of the hole in the masonry, if that makes sense.

I'd go ahead and drill most of the way into the wall -- five inches, 1/2 inch bolts. You should be good to go. How old is the brickwork?

One other option for really spreading the load along the length of the entire anchor is to just epoxy the suckers in there... they are then part of wall, and not exerting force ON the wall... of course your platform still vibrates....

Let me know how it goes!

Vini the second one is what i used directly into block work! its never moved in years mate!!

Block -- if filled correctly with concrete -- is WAY stronger than bricks. You could use 3" anchors and it would never budge (that's what I've got my platform mounted to now, Fingers, and I love it. Best case scenario, in my opinion) but brick's a different story.

UK, those expanding lead shields you used first aren't quite as good in my experience as the ones you just mentioned. Go five inches in, and you're good!

(ahem... no wisecracks, please!)

I think your suspicions could be spot on here UK. Those anchor bolts you're using need to be embeded all the way. Is removal of plaster in those sections an option? Put a diamond cutter blade on a 5" grinder and cut a pocket in the plaster where the studs sit
Threaded rod, chemical set (Hilti, chem set) would be a sure bet, you could have the anchor bolts as deep or as short as you like as long as you go at least 50-75% of the way into the brick.

Good luck.

[Griffin]

Bingo! I agree...

Chem set = epoxy, correct??

Too bad Everlast does not sell hard hats. Surely UK is not the only one this happened to.

Sorry it happened but it did make me laugh too, so not all is lost.

[Roc Stone]

Ya!

Not necessarily. Whilst the end result may be the same with chem set and epoxy it is important to note that these compounds do have varying strengths and applications.

But...Well noted!

Sorry to hear of the collapse, but glad to hear no one was injured. I'm sure the speed bag corner will be back and better than ever shortly.

The 80 lb heavy bag I keep on top of mine rolled off and hit me on the head about 3 weeks ago. It was a glancing blow, so no injuries. It's mounted securely now.

OK So I'll be using the Shield Anchor Loose Bolt M12 x 10mm x 80mm with epoxy.

Any ideas what size drill bit I should be using with these bolts?

Thanks for all your ideas guys. You've all been a great help.

[Roc Stone]

14mm

[ukspeedbag]

14mm

Thanks Roc!

A couple of other little tips (If you're not done already):

Never hurts to blow or vacuum the hole clean after you drill and before shooting the epoxy in...

The epoxy you're looking for is specifically FOR anchoring bolts in concrete -- not your typical everyday stuff. Over here it's grey and white, you use a special gun (like a caulking gun), and most importantly: has a long tip that mixes the two chemicals as it's being extruded from the tube.

Stick the tube ALL the way to the bottom of the hole and draw it out... you'll have some overflow when you put the anchor bolt in, but you won't have any air gaps, and that's what you're looking for.

UK, I predict you're going to be amazed at the difference -- your platform probably going to feel a lot more solidly mounted... good luck!

Were the 80mm the longest they had?

Thanks Griffin, your a gent! I will vacuum the holes I done this when I first drilled the wall. But seems I'll be opening the holes up, I'll do it again. I'm looking forward to getting it back up, the bedroom looks a right eye sore. And I'm sure it will reduce the vibration even more.

Yes 80mm is the longest they have. I'll be getting them tomorrow, hopefully they will have a drill bit and the epoxy too. Thanks very much for all your tips.

Thanks SBSH! I was devastated. I never got hurt mate. It was all kind of in slow motion. The lower fixings held and I kind of caught the sand bag with my head.

Anyway, I bit of a nightmare but should be good.
The reason why the top bolts ripped out of the wall was I had drilled into the mortar between the brick. When I came to open the holes up for the bigger anchor bolts, one of the holes was like a knife going through butter. I started to fill them with epoxy and the gun broke. I managed to get plenty in by mixing it myself and pushing it in. Not as good as the tube, but once I'd started there was no going back. The lower bolts are absolutely solid. The brick was b**ch to drill. The locals here, claim that it's the hardest brick money could buy. I never believed this until today.
So I have the wooden pieces mounted but, I'm going to purchase some through bolts, the ones where you drill through the work, insert the anchor and tighten. I'll drill a little higher through the wood and hopefully hit the brick with a masonry drill. I have proper gun at work so I'll also use the epoxy. I'll probably add another 2 bolts to the top wood. As it is, I'm certain it's going to be OK, but for a piece of mind and a few more days, I might as well. A bit long winded, but better safe than sorry.

Man I hate DIY!
