Prefabricated and assembly type steel reinforced concrete column with high-performance concrete frame and construction method
The invention discloses a prefabricated and assembly type steel reinforced concrete column with a high-performance concrete frame. The prefabricated and assembly type steel reinforced concrete column adopts an idea of partial prefabricated assembly and partial casting in situ and comprises a prefabricated part and a cast-in-situ part. The prefabricated assembly type steel reinforced concrete column comprises a prefabricated high-performance concrete hollow column, longitudinal bars, section steel, stirrups and cast-in-situ common concrete, wherein the longitudinal bars are arranged in the prefabricated high-performance concrete hollow column along the column-length direction; the section steel is arranged in the prefabricated high-performance concrete hollow column along the column-length direction; the stirrups are spread on the cross section of the prefabricated high-performance concrete hollow column at equal intervals; the longitudinal bars and the section steel are enclosed by the stirrups; a central cavity of the prefabricated high-performance concrete hollow column is filled with the cast-in-situ common concrete. The invention also provides a construction method. The prefabricated and assembly type steel reinforced concrete column with a high-performance concrete frame and the construction method disclosed by the invention have the advantages that the hollow prefabricated high-performance concrete column can generate circumferential constraining force for the cast-in-situ common concrete, so that the bearing capability is improved, the whole performance and the seismic resistance of the structure are improved, the deformation capability of a member in the process of transportation and lifting is improved, and the comprehensive improvement and enhancement of the stressing performance and the use performance of the prefabricated steel reinforced concrete member are realized.
