In general, when the balcony is designed, the end of the cantilever is designed according to the 1KN centralized load, and the plate surface is designed according to the live load per square meter. The laying of floor tiles will also increase the fixed load of about square meters, which basically does not affect the normal use of the balcony.
If you are really not at ease, you will remove the plastering layer on the surface of the balcony board, rinse it with water, and then pave the bricks, so that it will not increase the load much (it is more than ten kilograms per square meter).
If your balcony is not designed by the design department, it is indeed thin and few, you can use the top surface of the balcony board to remove the hair, and then pour a layer of 40 60 mm thick concrete to deal with, so that the new board and the old board will form a laminated board, according to the specification design and construction, to ensure that the board is not damaged.
There are a few things to note here:
1. The thickness and number of the post-poured concrete, whether it should be re-reinforced (it may not be necessary to re-re-reinforce), how much reinforcing and how to anchor the post-reinforcing bar should be determined by structural design professionals;
2. It is best to use fine stone concrete for post-poured concrete;
3. After adding a layer of concrete, the fixed load is increased more. Although there is no problem with the strength and stiffness of the slab, it also brings the problem of anti-overturning stability of the balcony (that is, to prevent the balcony from collapsing due to the end being pressed down and the root is warped) or the bearing capacity of the balcony beam. This should also be determined by the building structure designer after going to the site to check and calculate.
Therefore, if you really want to add a layer of concrete, it is recommended to ask a building structure technician to help, do not know to ask someone to find, structural safety is no trivial matter, be cautious, cut!
First use cement slurry to brush the place to be mended twice, and then mix it with two parts of cement, one part of sand and half part of cellulose.
It's good to do leveling, but you must clean the ground, and then brush the ground, after the solid brushing is done in the self-leveling leveling, two or three days after leveling, you should brush the water from time to time to moisten, so that basically it will not be hollow!!
Situation, specific treatment. It's best to find a powerful master, don't be afraid to spend a few extra dollars, really.
The thickness of the cast-in-place concrete balcony floor slab is not less than 100mm, and the general thickness is 120mm. Obey the annotation of construction drawings.
The installation of wooden ceilings is to find the height difference of the original cement floor slab. You can only adjust it when you hang the ceiling, and there is no way to earn it.
