Meshing-spliced multi-high-layer assembled steel structural system

The invention relates to a meshing-spliced multi-high-layer assembled steel structural system. The structural system is formed by assembling assembled floors and assembled flange columns through bolts. The assembled floors can be spliced to have a needed size and are spliced through bolts to form a whole floor of a building. The assembled floors are formed by corrugated web channel steel beams. The shear bearing capacity of the assembled steel beams is effectively improved. According to the steel structural system, industrialized production is achieved; the steel structural system is quickly assembled through high-strength bolts on the site, and therefore environmental pollution caused by concrete pouring and steel welding is avoided.
