Problems solved by technology
There are certain problems in the application of externally reinforced ring-slab joints commonly used in frame structures using concrete-filled steel tube columns in the past. The outer ring plate will affect the pouring of concrete outside the steel tube. Therefore, there is an urgent need for a force-transmitting, clear, Node form with reliable performance and convenient construction

Embodiment Construction
[0018] The present invention provides an assemblable concrete filled steel pipe composite column-steel concrete beam joint. The structure and specific implementation of the present invention will be further described below in conjunction with the embodiments of the accompanying drawings.
[0019] figure 1 and figure 2 It is a structural schematic diagram of an embodiment of the present invention, and the node is composed of a steel tube concrete composite column 1 and a steel concrete beam 2 . In the structure of the concrete-filled steel tube composite column 1, the cross-section of the steel tube 3 is square, and the end plate assembly 9 is a flat end plate; in the steel concrete beam 2, the profile steel 6 is an I-beam; The unilateral bolts 8 pass through the end plate assembly 9 and the steel pipe 3 in order to connect the steel pipe 3 and the section steel 6; the outside of the steel pipe 3 and the section steel 6 are respectively bound with column longitudinal reinforc...

The invention belongs to the field of structural engineering in civil engineering, in particular to an assembled concrete-filled steel tube composite-column-steel reinforced concrete beam node. Holes are respectively formed in a steel tube and an end plate component welded with profile steel, and a blind bolt sequentially penetrates through the end plate component and the steel tube to connect the steel tube and the profile steel. The outer parts of the steel tube and the profile steel respectively strap column longitudinal bars, column stirrups, beam longitudinal bars and beam stirrups to form a beam and column connection node. Internal concrete is deposited in the steel tube, external concrete is deposited outside the steel tube, and beam concrete is deposited outside the profile steel. The assembled concrete-filled steel tube composite-column-steel reinforced concrete beam node has the advantages of convenience in on-site assembly, reliable performance, good anti-shock and fire-resistant performance and the like and is suitable for multi-rise, high-rise, super high-rise or other relevant engineering structures.
Description
technical field [0001] The invention belongs to the field of structural engineering in civil engineering, and in particular relates to an assembleable steel pipe concrete composite column-steel concrete beam joint. Background technique [0002] Concrete filled steel pipe column is a combination of steel pipe and inner concrete. The concrete inside the steel pipe is restrained by the steel pipe, which improves its bearing capacity. The presence of concrete also restricts the inward buckling failure of the steel pipe. This structure is obtained in high-rise buildings a wide range of applications. The concrete-filled steel tube composite column is a new type of composite member developed on the foundation of the concrete-filled steel tube column, and the reinforcement is set outside the concrete-filled steel tube, and the concrete is poured. The increase in temperature improves the refractory performance of the column. In the frame structure using concrete-filled steel tube c...
