Cantilevered enough for me to be surprised, and also use prefabricated hollow slabs to make meter-long supports? And you are obviously making the main structure of the frame is basically the same as the steel frame structure, and there is no need for the load-bearing wall to support the top surface, and the top surface is an empty plate, not a pouring.
Summary. Your span is already relatively large, and if there is no wall below, it is better to have beams, and if there is a wall, it is not so large. >>>More
According to your description, as long as the reinforcement is reasonable and basically meets the requirements, so the reinforcement situation will be judged for you.
It's better not to, the distance is too long, it's not safe at all. If possible, a roof is poured directly with concrete. If you use prefabricated panels, you need to put several beams to connect the prefabricated panels.
There is no regulation for this, it depends on the design of your house, there are single doors, mother and son doors, and double doors. There are many double openings in rural areas, and there are many single-door doors and mother-in-law doors in villas. >>>More
The empty span of 8 meters in the living room of the rural building house is not hit by the beam, and it must be looked at, and it is very dangerous not to play.
