Problems solved by technology

[0002] With the development of high-rise buildings, rectangular steel tube concrete is adopted by more and more building structures, and at the same time, it gradually shows some shortcomings, mainly as follows: the restraint of concrete by rectangular steel tubes is not as good as that of circular steel tubes; in order to prevent buckling of steel tube walls, it is necessary to Controlling the width-to-thickness ratio results in waste of steel, and also limits the application of high-strength steel in CFST structures

Abstract

The invention discloses a rectangular steel tube concrete column and a construction method thereof. In the invention, a rectangular steel tube concrete column commonly used in engineering is improved, and a prestressing rod is additionally arranged in a rectangular steel tube structure. The rectangular steel tube concrete column is restrained by the prestressing rod, and a rectangular gasket is extruded by prestressing force of the prestressing rod, so that the rectangular gasket extrudes the wall of the steel tube, and then extrudes the concrete column, to improve the local buckling performance of the wall of the steel tube; and by using the structure, the local buckling capacity of the wall of the steel tube of the rectangular steel tube concrete column can be improved, and indicators of the column can be greatly improved. The column has the advantages of being simple in structure, low in cost and good in use effect.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a rectangular steel pipe concrete column and a construction method thereof. Background technique [0002] With the development of high-rise buildings, rectangular steel tube concrete is adopted by more and more building structures, and at the same time, it gradually shows some shortcomings, mainly as follows: the restraint of concrete by rectangular steel tubes is not as good as that of circular steel tubes; in order to prevent buckling of steel tube walls, it is necessary to Controlling the width-to-thickness ratio results in waste of steel, and also limits the application of high-strength steel in CFST structures. [0003] In order to improve the local buckling capacity of the steel pipe wall, the structural measures adopted include restraint tie rods, which can enhance the stability of the steel pipe wall by means of the tie effect of the restraint tie rods; set up the tr...
