Abstract:Based on the existing steel-reinforced sleeve extrusion connection technology, optimized by adding positioning steel pipe, a new type of beam-column joint system with steel-reinforced sleeve extrusion+steel pipe positioning connection was created, and it was proved that the joint has fine engineering seismic performance by experiment. Taking a teaching building with frame structure as application background, the key technology application of the beam-column joint with steel-reinforced sleeve extrusion+steel pipe positioning connection was mainly discussed. Engineering practice shows that the joint system has lots of advantage, such as safety and reliability, convenient construction, lower cost, good durability and wide scope of application. And the joint system can be used for connection of longitudinal steel bars of prefabricated columns and shear walls of general assembled building.
Keywords:sleeve; extrusion connection; positioning steel pipe; assembled building; connection technology of joint
