Modularized box type building prefabricated column and foundation slab dry type connecting structure

The invention discloses a dry type connecting structure of a modular box type building prefabricated column and a foundation slab. The dry type connecting structure comprises an upper sleeve assembly and a lower sleeve assembly. A plurality of upper connecting blind holes are formed in the bottom end of the prefabricated column, each upper connecting blind hole is connected with a corresponding upper sleeve assembly, a reserved groove is formed in the upper surface of the foundation bottom plate, a plurality of lower connecting blind holes are formed in the groove bottom of the reserved groove, each lower connecting blind hole is connected with a corresponding lower sleeve assembly, and the lower sleeve assemblies are connected with the upper sleeve assemblies. And the upper sleeve assembly and the lower sleeve assembly are mutually butted and clamped. Dry type connection of the prefabricated column and the foundation slab is achieved, connection is clean and tidy, the structural stability after the prefabric
