Modularized multistory and high-rise fabricated steel structure prestress center supporting system

The invention relates to a modularized multistory and high-rise fabricated steel structure prestress center supporting system, and belongs to the technical field of structural engineering. The modularized multistory and high-rise fabricated steel structure prestress center supporting system is formed by fabricated floor slabs, fabricated flange columns and fabricated prestress sway braces in a fabrication mode through bolts, wherein each fabricated floor slab comprises slabs A, slabs B and slabs C, and the fabricated floor slabs are spliced through bolts to form whole-storey floor slabs of a building. Beam column joints of the modularized multistory and high-rise fabricated steel structure prestress center supporting system are welded in a factory, connection between the fabricated prestress sway braces and a formwork is formed in the factory in a welding mode, rigid connection of the joints can be effectively achieved, welding quality is ensured, and structural stress is facilitated. According to the modularized multistory and high-rise fabricated steel structure prestress center supporting system, industrialized production is achieved, on-site rapid assembly is achieved, the construction speed is increased, the construction period is shortened, the project cost is reduced, environmental pollution is reduced, steel can be recycled after the modularized multistory and high-rise fabricated steel structure prestress center supporting system is disassembled, and the modularized multistory and high-rise fabricated steel structure prestress center supporting system is an environment-friendly structure system.
