Prefabricated reinforced concrete column with high-performance concrete frame and construction method
The invention discloses a prefabricated reinforced concrete column with a high-performance concrete frame, which adopts a thought of partially prefabricating and partially casting in situ, and is composed of a prefabricated part and a cast-in-situ part. The prefabricated reinforced concrete column with the high-performance concrete frame comprises a prefabricated high-performance concrete hollow column, longitudinal bars arranged in the prefabricated high-performance concrete hollow column along the length direction of the column, reinforcing steel bars and stirrups which are equidistantly paved on the cross section of the prefabricated high-performance concrete hollow column, the reinforcing steel bars crossing the central cavity of the prefabricated high-performance concrete hollow column, and the end heads of the reinforcing steel bars connected to the inner sides of the stirrups, and cast-in-situ common concrete filled in the central cavity of the prefabricated high-performance concrete hollow column. The invention further provides a construction method of the prefabricated reinforced concrete column, the prefabricated high-performance concrete hollow column is capable of generating an annular constraining force on the cast-in-situ common concrete, and thus improving the bearing capacity of the prefabricated reinforced concrete column, improving the overall performance and anti-seismic property of the structure, improving the deformation capacity of the member during transport and hoisting processes, and achieving comprehensive improvement and enhancement of the stress performance and the user performance of the prefabricated reinforced concrete member.
