Abstract

The invention discloses an assembling type frame structure joint which is applied to compound hollow steel tube concrete. The assembling type frame structure joint comprises a tenon column steel tube and a pier column steel tube. Concrete is added into the pier column steel tube to form a pier column. Concrete or steel ribs and concrete is or are added into the tenon column steel tube to form a tenon column. The tenon column is sleeved in the hollow pier column steel tube with the same axis, and two ends of the tenon column stretch out of the pier column steel tube. The tenon column is fixed in the pier column through the concrete added into the pier column steel tube. An outer wall adaptive position of the pier column is provided with at least one splitting plate. The assembling type frame structure joint has the advantages of being high in bearing capacity, simple inn structure and easy to machine. A novel assembling type frame structure is formed based on the joint. The novel assembling type frame structure can express advantages of compound hollow steel tube concrete members, promotes application and popularization, and satisfies requirements for rapid development of assembling type buildings currently in China. Advantages of high construction speed, small dead load, high bearing capacity and good fire resistance are achieved.

Description

technical field [0001] The invention relates to a building concrete frame structure node, in particular to an assembled frame structure node suitable for compound hollow steel tube concrete. Background technique [0002] In recent years, the design and manufacturing technology of CFST has developed rapidly, and has been widely used in many civil engineering structures such as high-rise buildings, long-span bridges, industrial buildings, transmission and transformation towers, and underground structures, and has achieved good economic results. and social benefits. The composite hollow concrete-filled steel tube concrete is a new type of concrete-filled steel tube structure developed on the basis of the traditional solid-section concrete-filled steel tube. It is a member formed by pouring concrete between two concentrically placed steel pipes. Compared with traditional steel tube concrete, it has the advantages of high bearing capacity, small dead weight, and good fire resis...
