Steel tube reinforced concrete composite special-shaped column with stiffening rib

Abstract

The application discloses a kind of steel pipe concrete combination special-shaped columns with stiffener, specifically relates to the technical field of building engineering, including: four steel pipes, four The stiffener is arranged in the steel pipe, and the inside of four steel pipes is filled with concrete;Fixed seat is located between four steel pipes, and the four ends of fixed seat are all equipped with the connecting arm towards steel pipe, the outside of four The first locating seat is equipped with the first locating seat of installation in four connecting arms, first locking assembly is arranged between the first locating seat and connecting arm, the outside of four The two second locating seats are symmetrically equipped with the installation of second locating seat in four steel pipes.The application is stressed by stiffener, steel pipe and concrete, and the vertical and horizontal load is evenly dispersed to each part of steel pipe and concrete, so as to improve the overall stress performance of steel pipe concrete column, optimize stress transfer path, avoid local stress concentration, greatly enhance the bearing capacity, shear performance and anti-deformation capacity of steel pipe concrete column.
