Rule in concrete wall easiest?

[-MH-]

I will attach a wooden batten (70x45) to a lightweight concrete wall/leca/concrete block with plaster. Is there a smarter way than what I've done so far? There are many steps, and getting all the holes to match is a bit exciting.

• Drill holes in the batten.
• Screw in the screws so they stick out on the backside.
• Press the batten against the wall so the screws mark the drill holes.
• Drill and plug the wall.
• Hope all the holes match, and I haven't drilled crookedly or the drill hasn't slipped.
• Screw the batten in place.

The batten will support tools and maybe a pegboard, so it's not a heavy load.

Drill two holes as you say. Attach the board. Drill the remaining holes when the board is in place. Attach a plug to the screw. Gently hammer the plug through the board, fasten it.

should have used lightweight concrete screws.

Or use nail plugs and drill through both the stud and the wall in one go. Then just hammer in the nail plug with a hammer. It holds like a rock.

nah. not exactly. loosening the nail plug just widens the hole

Some tips, please. Doesn't the hole in the beam become a bit large if you are going to drill through the whole way? Perhaps a washer? Which drill bit is used for both wood and concrete?

ordinary hammer drill. no, you get the fastening in the material behind. it would have been different if you predrilled for wood to wood mounting

Okay, so for those lightweight concrete screws that are 7.5mm, I use a hammer drill through both wood and concrete. Drill diameter?

It depends on the dimension of the screw - read the instructions for the screw you purchase.

I have used both facade plugs and lättbetongskruv for this, and both work well.

Here's some load testing for the facade plug:



I don't hang around anymore, but the facade does.

Just saw in the document that a 6mm drill is required. It also stated, "The full threading on the screw prevents the frame from being pressed against the building material." But don't I want the rule pressed against the wall?

I googled "fasadplugg" and I think I get it. The plug should go through both the stud and the concrete, so for a 45mm stud maybe a 10x120 might be enough. They cost 1000:-/50pcs at Beijer.

Aha!

Then I've learned something today as well Didn't know that the facade plug should also be in the beam. Imagine if I had known that when I set up the support beam for the terrace in the house

@MH: It's half price at byggmax - but still a rip-off.

Don't make it more difficult than it is now
I promise that my method will suffice for your purpose.

Visited the hardware store and the price for nail plugs was a few kronor each. Unfortunately, I forgot to check the price of facade plugs. The screws were from nilsahlgren.se, they have a good product catalog:

Nail plugs don't seem suitable for lightweight concrete, facade plugs are needed (a longer piece that protrudes, should be screwed in, not hammered in). Learned something there. Didn't buy anything, only have three holes left at the moment, it should work with regular plugs.

Nimhed, doesn't the screw head penetrate through the stud then?
