Fully-prefabricated concrete-filled steel tube frame structure and assembling method

Abstract

The invention provides a fully-prefabricated concrete-filled steel tube frame structure and an assembling method. The fully-prefabricated concrete-filled steel tube frame structure comprises stand columns, cross beams, first connecting pieces and second connecting pieces, wherein the stand columns comprise steel tubes and concrete in the steel tubes; prefabricated joints are arranged on the stand columns; cavities are formed in the end parts of the stand columns; connecting parts are arranged at the end parts of the cross beams; the first connecting pieces are arranged between the joints and the connecting parts and used for fixedly connecting the stand columns and the cross beams; the second connecting pieces are arranged between the two stand columns in the same vertical direction and are provided with ends corresponding to the cavities; and the two ends of each second connecting piece are correspondingly embedded into the cavities of the ends of the two stand columns, so that each second connecting piece is used for fixedly connecting each two stand columns in the same vertical direction. According to the fully-prefabricated concrete-filled steel tube frame structure and the assembling method provided by the invention, horizontal connection is achieved through the joints and the first connecting pieces, vertical connection is achieved through the second connecting pieces, and compared with on-site construction, the manufacturing quality and the stress performance of components are improved, construction is convenient, and the assembly efficiency is high, so that assembly type development of square steel tube concrete structures is easily promoted.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a fully prefabricated steel tube concrete frame structure and an assembly method. Background technique [0002] At present, in terms of housing construction in my country, on-site construction is still the main focus. However, with the increasing shortage of labor in the construction industry in our country, the traditional on-site construction method is unsustainable. In response to the call of the national policy, advocating green construction and vigorously developing prefabricated buildings have become the main task direction of the current construction industry development. The square steel tube concrete frame structure makes full use of the characteristics of square steel tube concrete, which has the characteristics of good integrity, flexible layout, relatively uniform rigidity of each part of the structure, convenient construction, short construction period...
