Example Embodiment

[0015] Example 1

[0016] figure 1 It is the structural connection node between the circular steel tube 1 and the circular concrete column 3 with the column inner section steel 4 and the steel beam 2 of the present invention. The specific structure is: the circular steel tube 1 is partially located at the periphery of the circular concrete column 3 in the node area, The steel pipe 1 is connected with the web 7 of the horizontal steel beam 2 in the node area, and the steel pipe is located between the upper flange 6 and the lower flange 8 of the steel beam, that is, the height of the steel pipe 1 is the same as the steel beam web 7, and the steel pipe 1 is on the steel beam web 7 places are disconnected and welds 5 are welded to the web on both sides of the steel beam web 7.

Example Embodiment

[0017] Example 2

[0018] figure 2 It is the structural connection node between the rectangular steel pipe 1 and the rectangular concrete column 3 with the column inner section steel 4 and the steel beam 2 of the present invention. The specific structure is: the rectangular steel pipe 1 is partially located on the periphery of the rectangular concrete column 3 in the node area, and the steel pipe and the node The connection structure of the horizontal steel beams in the zone is the same as in the first embodiment.

Abstract

The invention discloses a section steel concrete column-steel girder node which belongs to the technical field of building structures, solves the problem of high construction difficulty caused by field insertion of hoop reinforcement into a steel girder web plate and welding in a conventional section steel concrete column-steel girder node region. According to the technical scheme provided by the invention, the periphery of a node region section steel concrete column is provided with a steel pipe; the steel pipe is connected with the web plate of a node region horizontal steel girder; and the steel pipe is welded with the web plate on both sides connected with the steel girder web plate, so that the restriction effect of the node region is effectively enhanced and a remarkable effect is achieved. The section steel concrete column-steel girder node is a novel node form with the advantages of simple structure, convenience and quickness in constructing, capability of enhancing the concrete pouring quality of the node region, high shock resistance, high economic efficiency and high factory production degree.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a structural connection between a steel concrete column and a steel beam. Background technique [0002] Steel concrete columns have the advantages of high bearing capacity, good seismic performance and good fire resistance, and are widely used in high-rise frame structures, high-rise frame-shear wall structures or high-rise frame-tube structures in China. However, when the steel concrete column is connected with the steel beam, stirrups must be provided in the node area to restrain the concrete, so as to ensure that the longitudinal reinforcement, steel and concrete work together. However, in the traditional steel concrete column-steel beam joint, the stirrups need to be pierced through the web of the steel beam in sections and welded at the construction site, which makes the construction difficult; and the dense stirrups also make it difficult to pour con...
