ᐅ Building Stair Railings with Aerated Concrete Blocks – Is It Stable?

I have a question... Our construction manager wants to build a railing on our 1.07m (3.5 ft) wide concrete staircase using 7cm (2.75 inches) Ytong blocks and then plaster it...

From the beginning, we wanted a masonry railing, but now the stairwell opening is quite large, so a full wall from top to bottom across the two floors is no longer possible...

But will something like this hold? Has anyone done this before?

Is it then built directly onto the stairs or next to them?

..because in our case the stairwell will be very narrow, and I would actually prefer the side wall to act as a kind of railing… meaning not a continuous wall built straight up the middle.

Does something like that work? See both examples attached

I want it roughly like in your first picture…. I’m just concerned about the stability with 7cm (3 inches) Ytong blocks laid on concrete steps….

Well, that would interest me a lot too

But how is the Ytong fixed onto the concrete steps? Is there some kind of anchoring or are they just placed on top?

This can certainly be done with brackets, possibly supplemented with reinforcing bars.

I will ask again exactly how he attaches it there!

So, in our case, it was built up on the concrete staircase. The concrete itself did not have any embedded rebar or similar reinforcement. Unfortunately, I don’t have any more photos from the construction phase.

Well, for example, you could screw or anchor something to it to create a connection. And Ytong isn’t always the same; he could use a heavier version. So far, I have only seen posts concreted at the beginning and end, because a free-standing end is quite vulnerable and could break off if someone can’t find the straight path after having six beers.
