Anonymous users2024-01-21It depends on the design... The roof reinforcement of the balcony should be the same as the roof reinforcement of the slab connected to it (it may be a cross-slab stress bar);
It may also be different, depending on the design.
The balcony is generally 50 lower than the floor, so the balcony steel bar is a cantilever bar and will not be connected with the floor gluten, not to mention symmetry. If the cantilever plate is done as shown below, there is no symmetry. >>>More
The balcony is a cantilevered structure, and the upper part is mainly subjected to large tensile forces. >>>More
The reinforcement 25 threads of the beam are on the top, and the load-bearing beam reinforcement 25 threads are below.
Answer: 12 steel bars, balcony steel bar welding length 12d is welded 12 12 144 mm. Is the bottom poured single-sided welding and double-sided welding? How do you get this picture? Full pass! The L in this diagram represents how long the weld you are asking? >>>More
Because it's only a little bit, it's all counted by the number of meters.
