Reinforced steel column and ECC concrete combined joint and construction method thereof

Abstract

The invention discloses a reinforced steel column and ECC concrete combined joint and a construction method thereof. The reinforced steel column and ECC concrete combined joint comprises cross columns, four steel beam brackets, four vertically-arranged annular hoop plates, and ECC concrete poured in a section steel column and section steel beam end area; each cross column comprises a cross columnweb of a cross structure, and four cross column flange plates connected to the corresponding ends of the cross column web correspondingly; the inner end of each steel beam bracket is connected to thecorresponding cross column flange plate; each annular hoop plate is connected between the two corresponding adjacent steel beam brackets; and a strip-shaped penetrating groove is formed in each annular hoop plate. The characteristics of section steel and the ECC concrete are combined, thus the number of hoop bars and tapping can be greatly reduced while structural performance is improved, manufacturing is easy, and construction is convenient.

Description

technical field [0001] The invention relates to the field of steel concrete structures, in particular to a reinforced steel column and ECC concrete composite node and a construction method thereof. Background technique [0002] Steel concrete structures have the characteristics of high bearing capacity and good seismic performance, and are widely used in large public buildings and super high-rise buildings. However, in the core area of ​​ordinary steel concrete beam-column joints, it is necessary to arrange dense stirrups to restrain the concrete, so as to ensure that the longitudinal reinforcement, steel and concrete work together. Arranging stirrups in the core area of ​​the joint requires piercing the steel beam, which weakens the bearing capacity of the steel beam. At the same time, the intensification of stirrups leads to difficulties in concrete pouring and vibration in the core area of ​​the joint, and it is difficult to ensure the quality of concrete pouring in the ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a reinforced steel column and ECC concrete composite joint and its construction method, to solve the problem that the stirrups in the core area of ​​the steel concrete beam-column joint need to be perforated on the steel frame, and to improve the structural performance while satisfying the The need for mass production in engineering
