Prefabricated reinforced concrete column-steel beam cast steel joint
The prefabricated assembly type reinforced concrete column-steel beam cast steel joint comprises a prefabricated joint area, a prefabricated reinforced concrete column and a prefabricated steel beam, the prefabricated joint area comprises a steel sleeve, a stiffening rib plate is welded in the steel sleeve, and a cast steel connecting piece and a connecting plate are welded to the two ends of the steel sleeve; the steel sleeve is connected with the prefabricated short steel beam through the cast steel connecting piece and the connecting plate, concrete is integrally poured after the prefabricated node area and a reinforcement cage of the prefabricated reinforced concrete column are manufactured, and then the steel sleeve is connected with the prefabricated steel beam. According to the invention, the component size is reduced, and the transportation is convenient; all prefabricated parts are completed in a factory, only bolt connection needs to be carried out on site, and the influence of a heat affected zone generated by on-site welding on the joint mechanical property is overcome; positioning of beam columns in the node area is more accurate, and the construction efficiency is high; the steel sleeve generates a constraint effect on concrete in a node area, so that the stress performance is improved; the steel sleeve is wrapped with concrete without stirrups, and the node area is simple in structure and convenient to construct.
本发明公开了一种预制装配式钢筋混凝土柱‑钢梁铸钢节点，包括预制节点域、预制钢筋混凝土柱和预制钢梁，预制节点域包括钢套管，钢套管内焊接有加劲肋板，钢套管的两端焊接有铸钢连接件和连接板，钢套管通过铸钢连接件和连接板与预制短钢梁连接预制节点域和预制钢筋混凝土柱的钢筋笼制作完成后整体浇筑混凝土，然后与预制钢梁连接。本发明中，减小了构件体积，运输方便；预制构件全部在工厂内完成，现场仅需进行螺栓连接，克服现场焊接产生热影响区对节点力学性能的影响；节点域梁柱的定位更加的精确，施工效率高；钢套管对节点域混凝土产生约束效应，提高受力性能；钢套管处包裹混凝土无需设置箍筋，节点区构造简单，施工方便。
