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.
