Assembly type steel structure eccentric support meshing splicing system of node rigid connection

The invention relates to an assembly type steel structure eccentric support meshing splicing system of node rigid connection. The system is formed by assembling assembly type floors, assembly type supports and assembly type flange columns through bolts; the assembling assembly type floors can be spliced into required scales and are spliced through the bolts to form a whole floor of a building. Corrugated web channel steel beams are adopted for the assembly type floors. Webs of two corrugated channel steel beams at the joint of every two adjacent assembly type floors are in butt joint in a meshed mode, the webs are connected in an assembled mode through bolts, the assembled steel beams are in a meshed shape, and shearing-resistant bearing ability of the assembly type steel beams is effectively improved. Rigid connection is achieved through a steel frame, and performance of the system is effectively improved. The steel structure system is suitable for industrialized production and is assembled rapidly on site; meanwhile, on-site assembly is achieved by adopting the high-strength bolts completely, and environment pollution caused by concrete pouring and steel welding is avoided.
