Multi-high-rise assembly type steel structure system

The invention discloses a multi-high-rise assembly type steel structure system belonging to the technical field of structure engineering. The multi-high-rise assembly type steel structure system is formed by fabricating fabricated floors and fabricated flange pillars by adopting bolts, wherein the fabricated floors comprise boards A, boards B and boards C, and the fabricated floors are split jointed through bolts to form the whole floor of a building. The steel structure system combines modularization, industrialization and fabrication, realizes industrialized production, and is rapidly fabricated on the scene, thus the construction speed is increased, the construction period is reduced, and the project cost is reduced; and meanwhile the steel structure system is scene-assembled by completely adopting high-strength bolts, thereby the environment pollution caused by pouring concrete and welding steel is avoided; and when dismantled, structure members can be efficiently recycled, and therefore, the construction waste is reduced, the idea of environment friendliness is genuinely realized, and the green structure system is achieved.
