Industrial assembly type steel frame prestress eccentric supporting and meshing splicing system

The invention relates to an assembly type steel frame prestress eccentric supporting and meshing splicing system in the technical field of structural engineering. The structural system is formed by assembling assembly type floors and assembly type flange pillars through bolts. The assembly type floors can be spliced into the needed scale, and the assembly floors are spliced through the bolts to form a whole-storey floor of a building. Corrugated web U-steel beams are adopted in the assembly type floors, and webs of the two corrugated U-steel beams at the joint of two adjacent assembly type floors are in butt joint in a meshed mode, the webs are assembled and connected through the bolts, the assembled steel beams are in a meshed shape, and the shearing resisting and bearing capacity of the assembly time steel beams is effectively enhanced. Industrialized production is achieved with the steel-structured system, on-spot fast assembling is achieved, meanwhile, on-spot assembling is performed by totally adopting the high-strength bolts, and environmental pollution caused by concrete pouring and steel welding is avoided.
