One kind of a multi-level assembly engaging splicing center prestressing steel structure support system

The present invention relates to a multi-level assembly prestressing steel structure of the central support system of one kind of splicing nip. The architecture is fabricated by the floor, and the assembly of prefabricated supporting column flange bolts assembled; said floor fabricated into the desired size can be spliced ​​using the splice between the bolt fabricated floor, forming a building the entire floor slab. Prefabricated floor channel using corrugated web beams. Two corrugated web splice channel beams adjacent abutting engagement fabricated floor, assembled at a web connected by bolts, snap-like bearing steel beams after assembly, effectively improve anti-fabricated steel beam shear bearing capacity. Steel structure of the present invention enables industrial production, rapid assembly site, while the present invention is completely assembled on-site high-strength bolts, steel and concrete placement to avoid the environmental pollution caused by welding.
