Embodiment 1

[0025] As shown in the figure, the steel bar piercing type joint adopts the upper and lower steel bars passing through the joint area directly as the longitudinal reinforcement of the concrete beam, that is, the upper reinforcing ring 3 and the lower reinforcing ring 4 . At the same time, a vertical ribbed plate 1 is welded on the outside of the steel pipe arm to transmit the shear force. The steel pipe wall is provided with a steel pipe wall opening 2. Due to the existence of the core-through member, the internal force of the beam end is effectively transmitted to the core concrete, thereby improving the overall rigidity and seismic performance of the structure. This node is the node of the steel pipe coal gangue concrete column and the coal gangue concrete beam.

Embodiment 2

[0027] As shown in the figure, the ring beam joint is an improvement of the steel plate reinforced ring joint. Its form is to set a reinforced concrete ring beam around the steel pipe to transmit the bending moment; a ring steel bar is pasted and welded on the outer surface of the steel pipe in the middle or bottom of the ring beam, That is, the shear ring 5 is used to transmit shear force. The joints do not have any core-through members, and the shear force at the beam end is transmitted indirectly to the core concrete through the pipe wall; the tensile force of the longitudinal reinforcement at the beam end is also indirectly transmitted. This node is the node of the steel pipe coal gangue concrete column and the coal gangue concrete beam.

Embodiment 3

[0029] As shown in the figure, the reinforced ring joint is to weld the upper and lower rings outside the steel pipe to transmit the bending moment at the beam end. The upper flange 6 and the lower flange 7 of the steel beam are directly welded to the upper and lower reinforcement rings. The web 8 is directly connected to the steel pipe wall to transmit the beam end shear force. This node is the node between the steel pipe coal gangue concrete column and the steel beam.

Abstract

A steel tube coal refuse concrete beam and column joint relates to a concrete beam and column joint. The steel tube coal refuse concrete beam and column joint is composed of coal refuse concrete and a column and beam composed of a round steel tube or a reinforced steel bar coal refuse concrete beam. An industrial waste-coal refuse is taken as aggregate; the joints include a reinforced steel bar cross-core joint, a loop beam joint and a steel tube coal refuse concrete column and beam joint. The present invention employs self-ignition coal refuse as light aggregate. The production technology issimple, and only needs to break up coal refuse and screen to the required size fraction, and has the advantages of less production investment, low cost, reduced structure deadweight and cost; saving building material and increasing effectively used area; fast construction rate, reduce labor force fee, machinery fee, management fee, etc.

Description

technical field [0001] The invention relates to a steel pipe concrete beam-column joint, in particular to a steel pipe coal gangue concrete beam-column joint. Background technique [0002] The concrete-filled steel tube column utilizes the combined effect of steel tube and concrete in the stress process to give full play to the advantages of these two materials, so that the brittleness of concrete is greatly improved, and the local buckling of the steel tube is avoided or delayed, so that the steel tube concrete The column has high overall bearing capacity, good plasticity and toughness. At present, the application of concrete-filled steel tube columns in high-rise buildings in earthquake areas can solve the brittle failure problem of ordinary reinforced concrete columns, thereby relaxing the restriction on the axial compression ratio. Size, reduce the cost of the project. At present, the State General Administration of Building Materials, the Ministry of Construction, the...
