Can the beam and slab of the inspection lot wall column be connected with steel bars for one day?

You can't. According to relevant public information, concrete pouring is on the same day, and the inspection lot of concrete can be written on the same day, but the steel formwork cannot be written on the same day. Rebar refers to the steel used in reinforced concrete and prestressed reinforced concrete, and its cross section is round, sometimes square with rounded corners.
