Optimized node for penetrating steel bar into stiff column

The utility model relates to the technical field of building construction, in particular to an optimized node for a reinforcing steel bar to penetrate through a stiff column, which comprises a built-in steel pipe and a reinforced concrete beam arranged on one side of the built-in steel pipe, and further comprises a reinforcing steel bar connector and a reinforcing steel bar connecting plate which are both connected with the built-in steel pipe in a welded mode. The reinforcing steel bar connecting plates and the reinforcing steel bar connectors are arranged in a non-bilateral symmetry mode, installation can be convenient, the welding workload is reduced, the operability of connection of the complex concrete beam and the stiff column joint reinforcing steel bars is improved, the construction difficulty is reduced, the construction steps are simplified, and meanwhile the structural safety performance is improved. The beam reinforcing steel bars are connected with the reinforcing steel bar connecting plates thro
