Connecting joint of assembly type concrete prefabricated wallboards and installation method of connecting joint

WANG XIAOPING

The invention provides a connecting joint of assembly type concrete prefabricated wallboards and an installation method of the connecting joint. The connecting joint comprises a plurality of grooves which are formed in the periphery of the prefabricated wallboards, connecting plates and connecting bolts, the connecting plates and connecting bolts are embedded in the grooves, the grooves are symmetrically formed in the two faces of the prefabricated wallboards in the thickness direction, a plurality of through connecting holes are formed in the grooves, through holes corresponding to the positions of the connecting holes in the grooves are formed in the connecting plates, the connecting bolts penetrate through the two connecting plates in the two grooves symmetrically formed in the two faces of the prefabricated wallboards in the thickness direction and the connecting holes in the grooves, the two ends of the connecting bolts are fastened by utilizing nuts, and the connecting joints between the two prefabricated wallboards are connected and fastened by screwing the nuts. According to the connecting joint of the assembly type concrete prefabricated wallboards and the installation method of the connecting joint, through the provided connection mode between the prefabricated concrete wallboards, on-site complete dry method operation can be achieved, the installation efficiency of the prefabricated concrete wallboards is greatly improved, the on-site operation time is shortened, and the standardization degree is high.

本发明提供一种装配式混凝土预制墙板的连接节点及其安装方法，包括开设在预制墙板四周的若干凹槽，嵌设在凹槽内的连接板和连接螺栓，凹槽在预制墙板厚度方向上双面对称开设，凹槽内开设有若干贯穿的连接孔，连接板上开设有与凹槽内连接孔位置对应的通孔，连接螺栓穿过在预制墙板厚度方向上双面对称开设的两个凹槽内的两块连接板和凹槽内连接孔，连接螺栓两端头利用螺母紧固，通过旋紧螺母，连接紧固两块预制墙板之间的连接节点。本发明提供的预制混凝土墙板之间的连接方式，可实现现场的完全干法作业，大大提高预制混凝土墙板的安装效率，减少现场作业时间，标准化程度高。
