I have a question regarding heavy drywall hanging on a ceiling.
I need to hang drywall ceiling without any studs (drywall designed for moisture, vapor barrier, straight onto concrete ceiling).
I realize the proper way to to do this would be metal studs, however, I can not lower the ceiling any more than 2 cm to preserve the large room separating arch thing.
My question is about weight, the building is an old conrete block one, appartement is on 4th floor drywall is 125x1200x3000mm (room size is 4x3m. The drywall weight is around 35kg, I will be trying to distribute the weight from edge to edge to get some support from the walls instead of leaving one drywall sheet solely hanging in the middle.
Do I have anything to worry weight wise? As in, is it safe to mount around 110 kg of weight onto the ceiling that is roughly 3x4m in area?
For reference, the build is an old concrete block design: https://gyazo.com/09e079faf29c2988ef0b8ac8b237e49b.png
