There is another one. What we are doing now is different from the standard, that is, the columns are usually poured first, but the beams and slabs are slower than them, usually about 2 hours. The current practice is to pour all three together. The label of the column is bigger than that of the plate, so use the label of the column to pour it.
The construction joint is left at the bottom of the beam, but this area is not, because it is the intersection place, which can be called beam-column intersection.
