The invention discloses a prefabricated steel structure and a construction method thereof. The prefabricated steel structure comprises independent foundations, steel columns, foundation beams, steel I-beams, composite floor slabs and wall board structures; embedded parts are embedded in the independent foundations; each embedded part comprises an embedded part bottom plate, vertical anchor rods and a sleeve; outer threads are arranged at the upper parts of the outer side walls of the sleeves; circular plates are arranged in the positions, close to the upper ends, inside the sleeves; column bottom steel dies are arranged at the tops of the independent foundations; the sleeves are sleeved with the column bottom steel dies and are in threaded connection with the column bottom steel dies; thebottommost-layer steel columns are correspondingly inserted in the column bottom steel dies; every two adjacent layers of the steel columns are connected through connecting sections; the steel I-beamsare in bolted connection with connecting section main bodies through vertical end plates; and the composite floor slabs are in bolted connection with top flanges of the steel I-beams. By the aid of the prefabricated steel structure and the construction method, the technical problems that traditional prefabricated steel structures are low in factory prefabrication rate and field assembly rate, high in environmental pollution and low in construction efficiency, secondary fireproof coating is required for exposed beams and exposed columns of the steel structures, the building beauty is affectedand embedded walls in the steel structures are cracked from main bodies easily are solved.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, in particular to an assembled steel structure and a construction method thereof. Background technique [0002] At present, the construction field is vigorously promoting the development of prefabricated buildings to realize the industrialized production of the construction industry. The foundations of traditional prefabricated steel structures all need to be cast-in-place, and the assembly rate is relatively low; the exposed beams and columns of the steel structure need secondary fire protection coating, which affects the beauty of the building, and the flanges of the beam-column joints need to be welded, so the quality of the site is not suitable for control and The technical requirements are high; the embedded wall in the steel structure is easy to crack with the main body. Contents of the invention [0003] The purpose of the present invention is to provide a prefabricated ...
