Abstract

The invention relates to a square thin-wall steel pipe concrete filled steel column and steel girder prefabricated node structure and a construction method thereof. The square thin-wall steel pipe concrete filled steel column and steel girder prefabricated node structure is characterized in that a steel girder is connected with a square thin-wall steel pipe column through T-section steel or angle iron. The square thin-wall steel pipe column and the steel girder are provided with bolt holes. The square thin-wall steel pipe column and the steel girder are connected with the T-section steel or the angle iron by using shearing bolts. The internal of the square thin-wall steel pipe column is filled with concrete. Compared with the prior art, the structure has the following beneficial effects: the novel node saves steel products, and is light in weight, relatively high in bearing capacity, good in plasticity ductility, and reliable in mechanical property. Compared with a welding connecting node, the bolt connecting node does not have a site welding process, so processing quality is more reliable. The structure is advantaged by convenient field installation, fast construction speed, and good economical efficiency.
