Abstract

The invention relates to a prefabricated square steel tube concrete column component connection structure and a construction method thereof. Anchoring end heads with certain length are reserved at twoends of prefabricated square steel tube concrete column components; anti-shearing connection bolt holes are reserved in four sides of each anchoring end head; a connector is a square steel tube innersleeve; reserved bolt holes, corresponding to the anti-shearing connection bolt holes in the anchoring end heads of the prefabricated square steel tube concrete column components, are reserved in four sides of the square steel tube inner sleeve; spring pin bolts are arranged on four sides of the inside of the square steel tube inner sleeve; the positions of the spring pin bolts correspond to thepositions of the reserved bolt holes. According to the prefabricated square steel tube concrete column component connection structure, two prefabricated square steel tube concrete column components are combined into a whole body through the connector with the spring pin bolt type square steel tube inner sleeve structure; the reliability of joint connection of the square steel tube concrete columnsis ensured; the quality defects in connection of the conventional welding process and the complex technical requirements in connection of the conventional bolt process are avoided; the construction quality of full prefabrication, on-site rapid connection and assembly and integrated combination of the square steel tube concrete column components is achieved.

Description

technical field [0001] The invention relates to the construction of a square steel tube concrete column structure, in particular to a prefabricated assembled square steel tube concrete column component connection structure and a construction method thereof. Background technique [0002] Due to the combination of the respective advantages of steel and concrete, the square steel tube concrete column structure has greatly improved its bearing capacity and seismic performance, and has become the main structural component form of the steel-concrete composite structure. At present, the main connection methods of cast-in-place square steel pipe concrete column members are mainly welding, flange connection and bolt connection, so the construction strength is high, the technical requirements are high, and the construction quality is not easy to control. [0003] The prefabricated concrete structure system has a relatively high prefabrication rate, and the bearing capacity of the buil...
