Hi

this is a big discussion which we are having on the site
what is the correct detail here?
please see attached images
what is your experience and your advise?

I'd support the countertop from a bracket mounted to the wall to make the work easier to sequence. Baring that, I think that I'd try to tie everything together rigidly and attempt to make a moment connection of it.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

If that is granite, it will crack.

If you want something that looks like it is floating, find or fabricate some metal brackets. Do not embed it in the wall. That is not very user friendly.

When I am working on a problem, I never think about beauty but when I have finished, if the solution is not beautiful, I know it is wrong.

hi

and what amount the slab and stairs landings?

 

[nonplussed]

I would see this detail every other day in my office and we have had no problems that I know of. Just make sure there is bond breaker under the concrete and that the builder waits a couple of weeks before building the brickwork over, just like a stair landing. Try to avoid any positive connection between the concrete and brickwork to allow them to move independently.

hi nonplussed

do you also provide the expansion void in the back of the slab?
so plastic payers (bond breaker) on top and below the landing and brick wall?

would you then embed concrete countertops into walls or make them rather self supported on a half brick "separate-supporting-wall"

If the wall is masonry, I see two potential issues. First, I would be concerned that any load on the landing or deflection/rotation of the landing would tend to pop off the course of cmu above it. Secondly, if it is reinforced cmu, the embedded depth of the landing may interfere with reinforcing in the wall.

Is this a landing or countertop? It looks a little out of proportion to be a landing. If its a countertop, the construction sequence baffles me (countertops are usually an interior after thought, not installed w/ the heavy trades).

I would just mount a bracket off the wall or add a post below.

Hi MotorCity

the last image was a countertop but the same issue also appears on stairs landings when they shall be supported on half brick wall

even here for the countertop this shall be just a brickwall.
Which kind of bracket would you suggest? just a angel iron bolted to the wall and the countertop cast on top?

What is your opinion about the cracks in the plaster on the external side of the building? Possible?
