The main load-bearing of the assembled integrated ceiling is the peripheral support angle steel, and the expansion wire of the main keel at the top should be shorter, not to exceed the thickness of the floor slab, and pay more attention not to be too deep when drilling. It will not damage the waterproof layer of the roof.

It should be a leak in the upstairs neighbor's bathroom! Open the integrated ceiling as soon as possible and see where the cause is. Then the fat upstairs neighbor repairs as soon as possible!
The bottom surface of the triangular keel is about 5 mm from the bottom edge of the corner line, the height of the triangular keel is about 2 cm, and the main keel is 38 or 50 mm above, and the distance from the bottom edge of the corner line to the top surface is minus 5 to 8 cm is the required length of the screw rod.
There is no formula, it should be calculated according to your installation design drawings, if there is a 30X60 electrical appliance, the auxiliary keel should be arranged according to its long side direction.
Expansion screws for M6At least To make a hole 6cm deep.
