Industrialized modular multistory assembly type steel structure prestress center supporting system

The invention discloses an industrialized modular multistory assembly type steel structure prestress center supporting system, and belongs to the technical field of structural engineering. The industrialized modular multistory assembly type steel structure prestress center supporting system is composed of assembly type floor slabs, assembly type prestress center supports and assembly type flange columns in an assembly mode through bolts; each assembly type floor slab comprises a slab A, a slab B and a slab C, and the assembly type floor slabs are spliced through bolts to form a whole floor slab of a storey of a building. According to the industrialized modular multistory assembly type steel structure prestress center supporting system, modularization, industrialization and assembly are combined, industrialized production is achieved, assembly is rapidly carried out on the site, the construction speed is increased, the construction period is shortened, and the project cost is reduced; due to the fact that on-site assembly is carried out completely through the high-strength bolts, environmental pollution caused by concrete pouring and steel welding is avoided; the structural components can be efficiently recycled after being disassembled, the quantity of construction waste is reduced, the idea of environmental protection is really realized, and the industrialized modular multistory assembly type steel structure prestress center supporting system is an environmentally-friendly structure system.
