The invention relates to a fabricated frame structure node based on a screw mortise and tenon structure and belongs to the field of civil construction. The fabricated frame structure node is composedof a screw rod, a hollow inner thread pier column and a connecting fastener, wherein the screw rod is penetrated through a hollow inner chamber of the hollow inner thread pier column and is integratedwith the hollow inner chamber through threads; the connecting fastener is fastened and formed into a hoop by the screw and is fastened in an annular groove on the outer side of the hollow inner thread pier column; the length of the screw rod is more than the height of the hollow inner thread pier column, so that the screw rod can be exposed for a certain length on upper and lower sides when the screw rod is penetrated through the hollow inner thread pier column, so as to connect compound hollow concrete column components; beams and inclined struts of a steel structure can be connected with nodes through connecting fasteners. The fabricated frame structure node provided by the invention has the characteristics of simple structure, convenience in detaching, and the like. Based on the node,a novel fabricated frame structure system is formed after compound hollow concrete columns and steel structure beams are connected, so as to promote the application and popularization of the compoundhollow concrete-filled steel tube structures.
Description
technical field [0001] The invention belongs to the field of civil construction, in particular to an assembled frame structure based on a screw mortise and tenon structure. [0002] structure node. Background technique [0003] The construction industry is an important pillar industry for national economic construction and social development. In recent years, under the background of the country's increasing infrastructure construction, the construction industry has developed rapidly, which has led to the emergence of various new building materials and structural forms. Among them, the CFST structure has attracted the attention of the academic and engineering circles due to its high bearing capacity and excellent seismic performance, and has been widely used in the construction of high-rise buildings. Concrete filled steel tubes can be divided into solid type and hollow type according to their structural form. Compared with solid concrete-filled steel pipe members, hollow ...
