Pitch point rigid connection modularization assembly type steel structure central supporting system

The invention belongs to the technical field of structural engineering, and relates to a pitch point rigid connection modularization assembly type steel structure central supporting system. The structural system is formed by assembling assembly type floor slabs, assembly type central supports and assembly type flange columns through bolts. The assembly type floor slabs can be spliced into the required scale and connected through bolts. According to the pitch point rigid connection modularization assembly type steel structure central supporting system, industrialized production is achieved, rapid assembly on site is carried out completely through the high-strength bolts, environmental pollution is avoided, structural members can be efficiently recycled when dismantled, the green and environment-friendly idea is truly achieved, and the pitch point rigid connection modularization assembly type steel structure central supporting system is the green structural system.
