Discussion on 10-Story Building Renovation: Drilling Holes and Dealing with Large Open Spaces

Question

Hello, I am a resident of a 10-story building with the so-called big plate. During the renovation and drilling new holes in the ceiling, I broke through a thin layer of plaster (I don't know if it was even 1 cm thick) and a large open space appeared to me. It probably extends over the entire...

reaven22 · Answer

Maybe it's a suspended ceiling made of plasterboard. The board is 12mm thick.

Giselhert · Answer

It may be suspended, but I don't see any cardboard there. Its different thickness is strange. Where the hole was created, it is thin and crumbles from the touch, in other places it is over 5-6 cm and you can normally attach pins. In addition, there is a lot of debris on the mines, some fist-sized pieces.

Then put your phone in there with the lamp on and record the image in a circle and you'll see what's there.

Releasing the structure. In my house there are channels with a tubular cross-section (vertical) in the walls, so in the thinnest place the wall is also about 1 cm. It does not weaken the slabs too much, but significantly reduces the weight of the building and the pressure on the foundation.

This may be the so-called Ackerman ceiling.

Tommy82 · Answer

I agree with robokop, it could be an Ackerman brick ceiling.

Giselhert · Answer

There is solid concrete there, so bricks are not an option. I wonder if these are not deliberately created spaces to improve sound attenuation / reduce heat loss.

Hello!

Or maybe there is no point in making a theory, just look at the photo?

Giselhert you just hit the channel. Perhaps this hole was already made there at the construction stage and was covered with plaster by the contractors.
Often, the channels were used to pull wires and to make it easier, a hole was cut every 2 - 3 m, which was later covered with plaster.

Regards

Jan

Giselhert · Answer

If they are channels, as you suggest, they are in the shape of an inverted U, i.e. open from the bottom because there is only a thin layer of plaster there. I've sealed it with putty for now and hope the ceiling doesn't fall on my head one day

MiL999 · Answer

You must have recently moved in because there is not a single thing that will amaze you in a large slab

Giselhert · Answer

I've been living for 2 years now, so I managed to taste the charms of this building, but you're probably right, not one thing will surprise me yet

maciek_slon · Answer

You will be surprised when one day you discover, for example, bricked up 3-4 m ^ 2, somewhere near the hall

Meaning how?

Garbage chute?

Giselhert · Answer

Fortunately, there is no chute on our floor, but there are Prussians, or rather there were, fortunately, we managed to eradicate them in about a month for less than PLN 18 using borax-based powder. If anyone has problems with cockroaches, write and I will recommend you a really effective remedy.

carot · Answer

How good it is to live in your own home But I also used to live in an old block of flats in the People's Republic of Poland, and it's strange, but there were no vermin. Are they in every block?

retrofood · Answer

He had to be. So where is it?

maciek_slon · Answer

Utility rooms are sometimes made on the upper floors, sometimes the doors are bricked up; PI an empty chamber is created, I know people who enlarged their hall by breaking through to such rooms :-)

The perfect place for a wardrobe...

Łukasz-O · Answer

Very often these rooms were located at the back of the passenger lift shaft, which had a smaller shaft in relation to the freight one. Empty space was used in this way. Sometimes there were two rooms, a chute and a storage room. for strollers.

Giselhert · Answer

This is exactly what it looks like in this block. And the chute openings are on every second level, although in my opinion they should be bricked up because they spread only bacteria and bad smell.

stanislawl · Answer

Hello,

I have the same problem - hole in the ceiling. I "glued" the mounting foam, then I will apply the finishing coat. I hope it will be ok. Interestingly, I made it... with a broom stick (neighbors were making noise, I tapped to give a "signal for silence", and the stick got stuck).

That it is a ceiling "with channels" - I understand it. But ... from this hole a lot of crumbs spilled on me: concrete, bricks and some pieces of plywood (?) Where did it come from in the ceiling?

Regards
