Abstract

The invention discloses constraint type assembly compound concrete-filled steel tubular column and steel beam joints provided with reinforcing blocks. The constraint type assembly compound concrete-filled steel tubular column and steel beam joints provided with the reinforcing blocks fall into crossed joints, T-shaped joints, straight joints and L-shaped joints. Each joint comprises a compound concrete-filled steel tubular column, a first beam end connector, a second beam end connector, the first reinforcing block and the second reinforcing block, wherein the first beam end connector and the second beam end connector are each formed by welding a beam end cover board, a beam end connection board and two beam end reinforcing ribs, a second bolt hole is formed in the beam end connection cover board, a first bolt hole is formed in the beam end connection board, the first reinforcing block and the second reinforcing block are each formed by welding a piece of channel steel and a reinforcing block connection board, second bolt holes are formed in two sides of the channel steel, and a third bolt hole is formed in the other side of the channel steel. All the joints are connected through bolts completely, traditional stud welded connection is abandoned, construction and installation are convenient, the constraint pressure function is formed for concrete in the columns, and the joints can be detached and replaced.

Description

technical field [0001] The invention relates to a connection structure in building construction, in particular to an assembled composite steel pipe concrete column-steel beam node provided with sleeves and reinforcing blocks. Background technique [0002] Since my country's Ministry of Construction issued the "Implementation Outline of Construction Industrialization" in 1995, the Ministry of Housing and Urban-Rural Development has successively established bases or research centers such as "National Housing Industrialization Base" and "New Building Industrialization Integrated Construction Engineering Technology Research Center", aiming to vigorously promote my country's In the process of building industrialization, the "Guiding Opinions on Vigorously Developing Prefabricated Buildings" promulgated by the General Office of the State Council in 2016 emphasized that prefabricated buildings accounted for 30% of new buildings within ten years, and strongly encouraged the proposal a...
