Is there a problem with the exposed beams at the top of the balcony

This is the big question, not a joke, do you live in a commercial house or your own house?

There must be a problem, not in accordance with the requirements of the specification for planting reinforcement.

Not necessarily.

Regarding the question of whether the balcony should be made into a suspended ceiling, I believe many people are troubled. In fact, whether the balcony has a ceiling or not depends on the situation, you can't just know how to follow what others do, blindly obey, figure it out as soon as possible, don't wait for you to feel uncomfortable when you use it after completion, and then regret it, it's too troublesome. >>>More

I can confirm that there is no problem, I am super high-rise and involved in this kind of drawing. 400 kilograms per square is no problem with permanent bearing, if you are really not at ease, you can make a big foot.

This you have to see whether the upstairs decoration is before or after you, if it is before, then you have to decorate the wall or not, if there is a property, if it is after the decoration, then you go to the owner upstairs, see if they have a balcony pipe on that wall, if so, it may be their business, then you can find them to let them make a new balcony plumbing, if there is no balcony plumbing, Then you have to look for the property to see if the sewer pipe of the balcony has broken for a long time, so the wall will be like this.
