Assembling type embedded beam-column joint structure

Abstract

The invention discloses an assembling type embedded beam-column joint structure. The assembling type embedded beam-column joint structure is used for connecting steel beams and steel columns into a whole, the joint structure is constituted by a hollow cuboid-shaped core piece, and the four outer walls of the core piece are provided with connecting plates used for connecting the steel beams in a protruded mode correspondingly; two ranks of bolt holes are formed in the connecting plates corresponding to the steel beams, connecting pieces used for connecting the steel columns are symmetrically installed at the upper end and the lower end of the core piece, and flanges embedded with the steel columns are installed on the connecting pieces; and the connecting pieces and the steel columns are provided with bolt holes in a corresponding mode. While connecting safety and stability of the steel component beam columns are ensured by the structure, quick splicing can be conducted in a construction site; the overall property and the anti-seismic property are more excellent than traditional joints; and while stress concentration is reduced, the rule of connecting strengthening and component-constructing weakening is met, accordingly, structure damage caused by weak connecting is avoided, besides, the joint structure is very suitable for industrialization production, and construction is simple and rapid, so that the problems, caused by construction, of the joint quality and safety are reduced.

Description

technical field [0001] The invention relates to the field of steel structures in buildings, and more specifically relates to an assembled embedded beam-column node structure. Background technique [0002] Steel structure is a very commonly used building structure nowadays. It has the advantages of high strength, good plasticity and toughness, high degree of assembly, convenient construction and short cycle time. These advantages make steel structures not only suitable for industrial buildings such as factories, warehouses and auxiliary facilities in big cities, but also for comprehensive buildings such as shopping malls, gymnasiums, and office buildings. Therefore, steel structure buildings are widely used and have a very good prospect. [0003] However, steel structural components are prone to buckling, instability and brittle failure, and a large part of component instability and brittle failure occurs in the connection area of ​​beam-column joints. Unreasonable joint des...
