12. A fabricated structural column shoe node as defined in claim 1, wherein: the bottom of the prefabricated cup seat is embedded into the cast-in-place structural slab.
13. A method of constructing a fabricated structural column shoe joint as defined in any one of claims 1-12, including the steps of:
1) firstly, binding a steel reinforcement framework of the cast-in-place structural slab, then hoisting a prefabricated cup seat, and pouring concrete to complete the construction of the cast-in-place structural slab;
2) and hoisting the prefabricated column, respectively enabling three side walls of the prefabricated column to be close to the cup walls on three sides of the prefabricated cup rim seat, and pouring concrete into the prefabricated cup rim seat through a pouring opening between the other side wall of the prefabricated column and the cup wall on the other side of the prefabricated cup rim seat to complete the construction of a cast-in-place structure.
