The utility model relates to the field of construction engineering, in particular to a connection structure between a square steel pipe concrete column with an inner partition and a steel beam node. the

Background technique

With the development of building structures, the research and application of steel-concrete composite structures has been rapidly developed, and has become a recognized new structural system, which is juxtaposed with steel structures, wood structures, masonry structures and reinforced concrete structures, and Expanded to become the fifth largest structure. The steel-concrete composite structure gives full play to the material mechanical properties of the concrete under pressure and the steel under tension. Secondly, the application of steel is also conducive to reducing the excessive cross-section of the concrete structure, and the strong effect of the concrete material on the steel can reduce the steel structure. Requirements for fire protection. In addition, the above combined structure is also beneficial to the improvement of the anti-seismic performance. At present, steel-concrete composite structures, that is, steel-concrete composite structures, are widely used in many countries, and the domestic development is relatively rapid. the

Steel-concrete composite structures are mostly used in concrete-filled steel pipe structures. The so-called concrete-filled steel pipe structures are filled with concrete and compacted to increase the strength and rigidity of the steel pipes. This structure makes full use of the advantages of steel pipe and concrete, and has the advantages of high bearing capacity, good plasticity and toughness, and convenient construction. It is widely used in single-story and multi-story industrial factory columns, high-rise buildings and bridges. middle. Especially in recent years, with the promotion and application of residential steel structures, the frame structure system formed by steel pipe concrete columns and steel beams has been gradually applied and developed in engineering practice, and has achieved good economic and social benefits. the

At present, the joint forms of the square concrete filled steel tube columns and steel beams in my country mainly include the outer diaphragm type, the inner diaphragm type and the diaphragm through type. Among them, the through-type joint of the diaphragm requires that the square steel tube concrete column be cut off at the corresponding position of the upper and lower flanges of the steel beam, and the original square steel pipe is re-welded after the transverse diaphragm is welded at the corresponding position. The construction of this kind of joint is complicated, and the weld seam is relatively concentrated, so it is rarely used in our country. the
