There are no beams on the cantilevered balcony slabs, and such structural designs are not allowed in the current code, and the safety is poor. In the past, there was such a structure, which was cantilevered from the side beams, and the main reinforcement (stressed rib) of the plate was placed on the plate surface, and the distribution ribs were placed below.
If the balcony rests on the cantilever beam, the side beam should be set on the outside of the balcony board, and the balcony board transmits the force according to the two-way plate, and part of it is directly transmitted to the cantilever beam, and part is transmitted to the side beam, and then the side beam is transmitted to the cantilever beam. The reinforcement of the balcony slab should also be reinforced in the way of the cantilever slab, that is, the steel bar at the top of the slab should be set up along the length and appropriately strengthened.
The height of the cantilever beam can generally be taken L 8 L 4. >>>More
It is recommended that the upper rib is 4B22 or more, there are too many things to build on your beam, is it not okay? Why does it have to be a solid brick? Does the wall still bear the weight of the floor slab?
Cantilever meters of balconies, without beams is OK.
However, the thickness of the slab should be at least 130mm to 140mm, and the plate gluten of this cantilever slab is a calculation requirement, that is, it is larger than the general floor slab reinforcement. >>>More
