Abstract

The utility model relates to a square steel tube concrete column and steel beam node connecting structure with internal diaphragms, and belongs to the technical field of building structure engineering. The square steel tube concrete column and steel beam node connecting structure is composed of a square tube concrete column, a steel beam, the internal diaphragms, a steel beam web, angle steel connecting pieces and the like. A vertical groove is formed in the position, corresponding to the steel beam web, of a wall plate of the square steel tube concrete column, the size of the vertical groove is the same as that of the steel beam web, and the vertical groove serves as a channel allowing the wall plate of the square steel tube concrete column to pass. An upper flange of the steel beam and a lower flange of the steel beam are directly welded onto the wall of the square steel tube concrete column and the web is connected with the angle steel connecting pieces on the two sides of the column through high-strength bolts. The internal diaphragms are arranged in the square steel tube concrete column, the upper internal diaphragm and the upper flange of the steel beam are located in the same horizontal plane and the lower internal diaphragm and the lower flange of the steel beam are located in the same horizontal plane. The square steel tube concrete column and steel beam node connecting structure with the internal diaphragms is simple in structure, convenient to process and install, clear and reliable in force transmission, and capable of meeting the requirements of industrial production; and the overall anti-shear capacity and the overall anti-bending capacity can be improved, it is guaranteed that the square steel tube concrete column and the steel beam work together, pressure and tension can be effectively transmitted and force transmission is clear and reliable.

Description

A kind of band internal partition concrete-filled steel square tubular column and steel beam joint syndeton
Technical field
The utility model relates to building engineering field, especially relates to a kind of band internal partition concrete-filled steel square tubular column and steel beam joint syndeton.
Background technology
Development along with building structure, research and the application of steel-concrete combined structure are launched rapidly, so far become a kind of generally acknowledged new structural system, itself and steel work, wooden construction, masonry structure and reinforced concrete structure are arranged side by side, to be expanded into the fifth-largest structure.Steel-concrete combined structure has been given full play to concrete and has been born pressure and the mechanical properties of materials of steel bearing tension, secondly, the application of steel also helps the heavy in section of crossing of reducing concrete structure, and concrete material can reduce in steel work fireproof requirement the strong effect of steel.In addition, combinations thereof structure also helps the improvement of anti-seismic performance.At present, steel-concrete combined structure is that steel-concrete combined structure is extensive in a lot of countries use, and domestic development is also rapider.
In steel-concrete combined structure, applying more is encased structures, so-called encased structures be exactly concrete is poured in steel pipe and tamping to add the strength and stiffness of big steel pipe.This structure has been given full play to the strong point of steel pipe and concrete bi-material, has that bearing capacity is high, plasticity and an advantage such as good toughness, easy construction, is widely used in the structures such as individual layer and multi storied industrial factory building post, highrise building and bridge.This year particularly, along with the promotion and application of steel structure of housing, the frame structure forming with steel core concrete column and girder steel ties up to and in engineering practice, is applied gradually and develops, and has obtained good economic benefit and social benefit.
At present, it is through that the connected node form of the concrete-filled steel square tubular column of China and girder steel mainly contains external partition formula, internal partition formula and dividing plate.The through node of its median septum requires concrete-filled steel square tubular column bottom flange correspondence position on girder steel to block, and diaphragm is welded in behind relevant position, again welds former square steel pipe.This node construction is complicated, and weld seam is more concentrated, and in China, application is less.
