[0059] This connection node adopts dry connection point support, which is a flexible support method that can adapt to the deformation capacity of the main structure. The point-supported external wall panel has the advantages of clear force on the wall panel components and connection nodes, can fully adapt to the deformation of the main structure, simple construction and installation, and controllable accuracy and quality. The node design meets the goal of not yielding under rare earthquakes: elastic for small earthquakes, elastic for medium earthquakes, and not yielding for large earthquakes.

The sliding part and the wall panel are connected by bolts and are designed with adjustment long holes for easy installation. This connection part can not only ensure the overall stability and strength of the connection between the beam column wall and the wall panel, but also, compared with the simple welding method, the method of bolt installation or anchor bolt + local welding can better absorb the deformation energy of the wall panel and beam bolt, so that the node deformation of the wall panel under various stress conditions is coordinated with the deformation of the main structure. This node has a reasonable structure, is easy to install, saves materials, reduces costs, and is suitable for popularization and application.

[0061] This connection node changes the conventional practice of common external wall panels, making the connection of external wall panels more reasonable, more convenient for construction and installation, saving materials, reducing costs, increasing installation speed, and saving labor. This connector can not only ensure the overall stability and safety of the assembly connection between the main structure and the wall panel, but also ensure that the node deformation is coordinated with the main structure deformation under various stress conditions. This connector and the connection installation method can be used in reinforced concrete frame structures, frame shear wall structures and shear wall structures, as well as external wall panels of various steel structure systems.
