problem of closure

[melkor19]

Do you think I should do a hollow floor tiling on the outermost part of the 50 cm closed protrusion, because in the two parts that are the beginning of the consoles, there is a horizontal beam, because the interior part is smolen flooring... or it would be healthier to attach 25/50 beams to the horizontal beam and make the floor thickness 15 cm, 7 meters long 50 Does a place with cm protrusion also meet the requirement that the height of the beam cannot be less than 3 times the thickness of the floor in the floors carried by the cantilever beams.
