Glue joist hangers to concrete blocks?

[gunillahelena]

Would it be possible to glue metal joist hangers on top of a low retaining wall of concrete blocks and then attach posts for a trellis in these? If so, what is the absolute best adhesive? Has anyone tried this? How does it perform in cold weather vs. sunlight?

Why not just screw or nail plug?

 

[gunillahelena]

I have neither the tools nor the body strength to drill into concrete. Adhesive sounded so smooth...

Glue will never work

I mounted mine with nail plugs.
With a powerful hammer drill, it goes in no time.

Strength is not needed to drill into concrete. Just think through the work beforehand. Remove items that are in the way, maybe use a proper stool to stand on to get a decent working height, etc. Concrete blocks can even be handled by the cheapest drills costing a few hundred kronor.

149kr and surely works for drilling multiple holes.

Even the cheapest drills for a couple of hundred bucks can handle concrete blocks.

With a proper hammer drill, you just need to hold the machine near concrete, and it will make a hole.

Drill, indeed! Thanks for all the tips!

Or you can get yourself a "real" machine for a few more bucks:

You can also rent at various hardware stores and other firms.

Expect it to cost around 200 to rent a real machine at a rental company, and yes, there is a difference between Bilteman and a real Hilti.

Probably the most cost-effective option is to rent a Hilti. It's pointless to buy a percussion drill for 149 SEK and expect to drill many holes in concrete stones. You'll end up vibrating for hours without getting much drilled. A rotary hammer is the only thing that works for anything other than aerated concrete.

Upon closer inspection of gunillahelena's problem, she says she's going to place the post shoes on top of the wall. This could mean that the concrete blocks used for the wall have holes facing upwards. This makes it quite difficult to secure anything in them with plugs.

It feels like the right advice, without having seen the wall, would be to drill large holes down into the wall. Insert the iron into a post shoe in the hole and fill it with some quick-setting mortar or glue.

Otherwise, setting a post upwards with wind and other forces likely won't hold. There's a risk the top stone in the wall will just break loose.

I think it's starting to get a bit out of hand here now. Renting hilti machines? Cementing in beam supports?
It's about drilling into concrete stone to set up a trellis.
Any drill with the slightest hammer function can handle that. The cheapest at biltema or a small cordless screwdriver with hammer.

If gunillahelena is unlucky, the concrete is of better quality. That happened to me!
I got a machine from Rusta similar to this one

for 299:- I've had it for 45 years now. And I don't regret it at all.
All concrete drilling work goes like butter.

It is 268% more expensive.
