It's really lucky to open 45mm without exposed steel bars, you look carefully, the general steel bars are 20mm away from the outer wall, if the steel bars are really not cut, it is really lucky (if you cut off the meter long transverse vertical steel bar, that is a disaster), it really doesn't matter much as you said, make up the incision with cement mortar, there is no problem with installing the range hood, but you have to remember the location of the transverse incision, don't punch holes in this place.
He meant to be waterproof and moisture-proof, but it added a large self-weight load, which was not in line with the requirements, at least it was not correct. There is no code that says that load-bearing bricks should be used to build a curved tank infill wall, so there is no question of 'why'!
You can't smash it casually, because the shear wall is also a weighing structure, unless you have the original design unit or other units with the same qualifications as the original design unit to issue a verified certificate, if you are responsible, don't smash it, it's safe. >>>More
It does not need to be a shear wall, it is generally not a shear wall, and it is possible that the sub-household wall is a shear wall or a section of wall limbs, and the bathroom is located right there.
The concrete ring under the bathroom wall is a waterproof concrete retaining wall foundation, not a ring beam, not a shear wall!
