A prefabricated steel structure building system and its construction method

Abstract

The invention provides an assembled steel structure building system and a construction method thereof. The assembled steel structure building system comprises a steel structure framework system, an assembled and integrated floor system, an assembled outer wall system and an assembled inner wall system; the steel structure framework system comprises double layers of steel plate concrete combined shear wall, steel tube concrete pillars, H-shaped steel beams and connection joints. The steel beams in the steel framework system serves as supports of the assembled and integrated floor system, and the assembled and integrated floor system comprises a precast concrete bottom plate, a cast-in-situ concrete super-position layer and an overhead floor layer located on the cast-in-situ concrete layer. The assembled outer wall system comprises a heat preservation and decoration integrated plate system, a waterproof interface layer and a base wall. According to the assembled steel structure building system, the design concept of separating a supporting body from a filling body is adopted, a large-span space capable of being divided flexibly can be provided, and the assembled steel structure building system and the construction method thereof have the advantages of being high in construction speed, reliable in quality and good in anti-seismic property.

Description

Technical field [0001] The invention relates to the technical field of building structures, in particular to a fabricated steel structure building system and a construction method thereof. Background technique [0002] Traditional buildings use cast-in-place concrete floor slabs, which require formwork and erect scaffolding, and can only be constructed layer by layer; the block walls, plastering or tiled exterior walls require exterior wall scaffolding, and the construction is complicated. Traditional building pipelines are mostly embedded in the structural floor and slotted and fixed in the wall. Once the pipeline is damaged, the structure or the outer protection system needs to be destroyed, which will affect the life of the overall building. Improving the construction quality of the building, shortening the construction period of the building, increasing the life of the building, and providing users with flexible and variable space are the requirements of the development of th...

[0002] Traditional buildings use cast-in-place concrete floor slabs, which require formwork and scaffolding, and can only be constructed layer by layer; block walls, external walls plastered or tiled, require external wall scaffolding, and the construction is complicated

Traditional building pipelines are mostly pre-buried in the structural floor and fixed in the wall by slotting. Once the pipeline is damaged, the structure or external protection system needs to be destroyed, which will affect the life of the overall building.
