The invention relates to an assembly type steel pipe concrete column connection structure, belonging to the technical field of civil engineering architectural component design, the lower end of a lined steel pipe (3) with lumbar ribs is located in a steel pipe lower column (5), the lumbar ribs and the steel pipe lower column (5) are welded at a lower welding line (6); the upper end of the lined steel pipe (3) with the lumbar ribs is located in a steel pipe upper column (4), the lumbar ribs and the steel pipe upper column (4) are welded at an upper welding line (7); the lower welding line (6) and the upper welding line (7) both are groove welding lines, the weld line strength is greater than the strength of a base material; and the steel pipe upper column (4), the steel pipe lower column (5) and the lined steel pipe (3) with the lumbar ribs are round steel pipes or rectangular steel pipes. Nodes of the assembly type steel pipe concrete column connection structure can be processed in a factory, component factory and standardization production and on-site construction assembly can be implemented, and the assembly type steel pipe concrete column connection structure has the advantages of being simple in structure, accurate in forming, fast and convenient in on-site construction, and beneficial to improve the work efficiency and the project quality.
Description
Technical field: [0001] The invention relates to a fabricated steel tube concrete column connection structure, which belongs to the technical field of civil engineering building component design. Background technique: [0002] Concrete-filled steel tube structure is the main load-bearing system of high-rise and super high-rise buildings. Concrete-filled steel tube column-steel beam structures with circular and rectangular sections are the most important structural form. The beam-column joint is a key part in the design and construction of the concrete-filled steel tube structure. It not only directly affects the overall rigidity, force performance and safety performance of the structure, but also affects the difficulty of construction and the progress of the project; the field welding of this structure The workload is large, the welding technology requirements for workers are high, and the construction quality is not easy to guarantee. Therefore, how to ensure the quality of the...
