Anonymous users2024-01-23Generally speaking, unless the building as a whole sinks, it will lead to the sinking of the floor slab, and it is even more difficult to have only the balcony slab sinking and the other building structures not sinking.
The reason for the sinking of the fourth-floor balcony you mentioned should be that the cushion on the balcony floor slab is hollow and delaminated, resulting in the partial collapse of the cushion.
The cracks on the balcony on the first floor are caused by the dry ash lamination of the tiles or the hollowing of the protective cushion of the floor slab.

You find someone who will take a look, if it's okay, so be it, if the house has been taken and then closed, it's really difficult to deal with, if you don't live in it, you will die with them.

Cantilever meters of balconies, without beams is OK.
However, the thickness of the slab should be at least 130mm to 140mm, and the plate gluten of this cantilever slab is a calculation requirement, that is, it is larger than the general floor slab reinforcement. >>>More
The problem should not be big, the general balcony to drill is also on the beam, you will not always punch holes in the beam, the beam reinforcement is up and down, but compared with the beam, the beam is the upper reinforcement force. If it is a beam extending outward from the side of the wall, it is not a big problem, if it is a connecting beam between two beams, or the beam on the door head is not a big problem, but it is recommended to remedy it according to what was said upstairs, that is, after chiseling, weld the steel bar of the same diameter and then fill in the fine stone concrete. It's safer that way. >>>More
As far as I know, in recent decades, the allowable live load of the balcony stipulated by the national code is 2KN per square meter (about 200 kg square meters), and the end of the balcony can also bear another 10KN (about 100 kg) of concentrated live load per linear meter. Your house is an old house, and the actual use can be slightly smaller than the above value, and it is better to place heavy objects as close to the root of the balcony as possible.
The height of the cantilever beam can generally be taken L 8 L 4. >>>More
