Prefabricated assembly type concrete structure primary and secondary beam connecting joint and mounting method
The invention discloses a prefabricated assembly type concrete structure primary and secondary beam connection joint and an installation method, and belongs to the technical field of assembly type house connectors, the prefabricated assembly type concrete structure primary and secondary beam connection joint comprises a prefabricated secondary beam and a prefabricated main beam, when the prefabricated secondary beam is machined in a factory, a square steel pipe is added to the end of the secondary beam, concrete is poured into the square steel pipe, and studs are arranged on the outer side of the pipe wall; and the bolt and the concrete part of the prefabricated secondary beam are stressed together. The method for prefabricating the main beam is related to the drawing set, and notches are reserved in the related positions connected with the secondary beams. During on-site installation, the square steel pipe is directly placed on a notch of the prefabricated main beam, the main beam does not need to be provided with an embedded part any more, cattle-shaped bearing plates and embedded parts in related nodes of an atlas can be replaced through the mode, the shear-resistant bearing capacity of the end of the secondary beam is improved, the machining cost of the steel plate is reduced, and the construction speed is increased.
本发明公开了一种预制装配式混凝土结构主次梁连接节点及安装方法，属于装配式房屋连接件技术领域，包括预制次梁和预制主梁，所述预制次梁在工厂加工时，次梁端头加入方钢管，方钢管内灌入混凝土，管壁外侧布置栓钉，通过栓钉与预制次梁的混凝土部分共同受力。所述预制主梁做法同图集相关做法，在与次梁连接的相关位置预留槽口。现场安装时，本发明方钢管直接搁置在预制主梁槽口上，主梁无需再设置预埋件，通过此种方式可取代图集相关节点中牛担板和预埋件，提高了次梁端部的抗剪承载能力，降低钢板的加工费用，提高了施工速度。
