Modularized multi-storey and high-rise assembly type steel structure system for achieving rigid joint connection

The invention provides a modularized assembly type steel structure system for achieving joint rigid connection, and belongs to the technical field of structural engineering. The structure system is formed by assembling assembly type floor slabs and assembly type flange columns through bolts. The assembly type floor slabs can be spliced into the required scale and are spliced through bolts to form the whole layer floor of a building. The steel structure system is suitable for industrialized production and can be quickly assembled on the site, the structure system is assembled on the site completely through the high-strength bolts, environmental pollution caused by concrete pouring and rolled steel welding is avoided, after being demounted, structure components can be efficiently recycled, the environment friendliness concept is truly achieved, and the structure system is environmentally friendly.
