装配式框架结构主次梁节点施工工艺

Construction Technology of Primary and Secondary Beam Joints of Prefabricated Frame Structure

针对装配式框架结构主次梁节点不同的连接做法,着重分析了主次梁均预制情况下的主梁预留后浇槽口及次梁预留后浇段这2种形式的节点做法与施工工艺,以及主梁现浇而次梁预制情况下的施工工艺,研究做法的特点及施工上的难点问题,并提出解决措施,以保证所应用项目上主次梁施工的顺利进行。

As to the different connection methods of the main and secondary beam joints of the prefabricated frame structure,the joint methods and construction technology of the two forms of the reserved post pouring notch of the main beam and the reserved post pouring section of the secondary beam when the main and secondary beams are prefabricated,as well as the construction technology when the main beam is cast-in-place and the secondary beam is prefabricated.The characteristics of the method and the difficult problems in construction are studied,and the solving measures are puts forward,so as to ensure the smooth construction of the main and secondary beams in the applied project.
