specific Embodiment 2

[0044] Specific embodiment 2 of the connection node between the steel concrete beam and the steel pipe concrete column of the application: as image 3 As shown, the difference between this embodiment and the specific embodiment 1 is that there is only one pair of steel beam connectors, the middle upper longitudinal reinforcement 2021 passes through the steel pipe concrete column 201, and the outer upper longitudinal reinforcement 2022 passes through the outer circumference of the steel pipe concrete column 201. Pass.

specific Embodiment 3

[0045] Specific embodiment 3 of the connection node between the steel-concrete beam and the concrete-filled steel pipe column of the present application: the difference between this embodiment and the specific embodiment 1 is that both the upper longitudinal reinforcement and the lower longitudinal reinforcement bypass the concrete-filled steel pipe column from the circumferential direction of the concrete-filled steel pipe column .

specific Embodiment 4

[0046] Specific embodiment 4 of the connection node between the steel-concrete beam and the concrete-filled steel tube column of the present application: the difference between this embodiment and specific embodiment 1 is that the middle upper longitudinal bar and the middle lower longitudinal bar bypass the steel-filled steel tube concrete from the circumferential direction of the steel tube concrete column The column, the outer upper longitudinal reinforcement and the outer lower longitudinal reinforcement pass through the steel tube concrete column.

Abstract

The invention relates to a connection node between a shaped steel concrete beam and a steel tube concrete column. The connection joints between steel concrete beams and steel pipe concrete columns, including steel pipe columns; beams and steel beam connectors, there are at least one pair, and the same pair of two steel beam connectors are located on both sides of the steel pipe column; each pair of steel beam connectors is equipped with There are upper longitudinal reinforcement and lower longitudinal reinforcement, and the upper longitudinal reinforcement and lower longitudinal reinforcement are arranged along the corresponding steel beam joint and cross the steel pipe column; the upper and lower longitudinal reinforcement corresponding to the same pair of steel beam joints are surrounded by Stirrups, and together with the stirrups form a reinforcement cage. The upper and lower longitudinal bars and stirrups form a reinforcement cage, and the upper and lower longitudinal bars correspond to the steel beam connectors on the opposite sides of the steel pipe column at the same time, that is, the reinforcement cage corresponds to the steel beam connectors on the opposite sides of the steel pipe column at the same time. A part of the bending moment is transmitted to the opposite side through the reinforcement cage, which reduces the stress concentration of the steel beam and the steel pipe column, and optimizes the stress of the connection node between the steel concrete beam and the steel pipe concrete column.

Description

technical field [0001] The invention relates to a connection node between a shaped steel concrete beam and a steel tube concrete column. Background technique [0002] In the frame structure formed by CFST columns and steel beams, the joints between CFST beams and CFST columns play an important role in transmitting shear force and bending moment, and the performance of the joints between CFST beams and CFST columns directly affects the performance of the frame structure , is an important part of the frame structure. The joints between steel concrete beams and concrete-filled steel tube columns mainly include outer ring plate type, inner diaphragm type and diaphragm through-type. One outer ring plate (upper and lower outer ring plates) is welded at the flush position of the flange, and the outer ring plate web welded on the outer wall of the steel pipe column is arranged between the two outer ring plates. 1. The lower flange and the corresponding outer ring plate are connect...
