Partially prefabricated high-strength steel reinforced concrete cross-shaped column

Abstract

The invention discloses a partially prefabricated high-strength steel reinforced concrete cross-shaped column. The partially prefabricated high-strength steel reinforced concrete cross-shaped column comprises a partially prefabricated high-strength steel reinforced concrete cross-shaped column shell and internal cast-in-place concrete, wherein the shell comprises prefabricated concrete and a cross-shaped steel-steel reinforcement framework; the cross-shaped steel-steel reinforcement framework comprises cross-shaped steel surrounded by stirrups and longitudinal bars; side wing steel plates are connected to the end parts of cross-shaped steel webs; the two sides of the side wing steel plates are connected through pattern steel plates and are welded at intersection nodes; and the internal cast-in-place concrete is poured in an internal cavity of the partially prefabricated high-strength steel reinforced concrete cross-shaped column shell. The partially prefabricated high-strength steel reinforced concrete cross-shaped column solves the problems of difficult hoisting and transportation and environmental pollution, reduces cracks generated by strength difference between the cast-in-place concrete and the prefabricated concrete, enhances the bonding structural strength and durability of post-poured concrete and a prefabricated part, is better in anti-seismic performance, and prominently improves the bearing capacity and the ductility.

Description

technical field [0001] The invention relates to a prefabricated and assembled steel concrete special-shaped column, in particular to a partially prefabricated and assembled high-strength steel concrete cross-shaped column. Background technique [0002] The composite structure of steel and concrete has been developed so far, and great achievements have been made. Steel concrete has the advantages of both concrete and steel, and can make up for their respective shortcomings. Due to its good mechanical performance and characteristics, the structure formed by the two complementing each other is one of the current development trends in the construction industry. [0003] The traditional construction method in our country is on-site construction, but as the voice of "green building" is getting higher and higher, this construction method can no longer meet the society's requirements for low consumption and green environmental protection. And the steel concrete structure is differe...
