At present, the lightweight prefabricated interior partition wall system mainly adopts the skeleton partition wall, which has been widely used in various aspects of the construction industry due to its industrial production and easy installation, but many problems have been exposed during the use process, mainly It is manifested in the following aspects: 1. Due to the light and thin steel frame used by the keel, when the panel is installed on the steel frame by nailing, it cannot be fixed well, making it difficult to guarantee the stability of the entire skeleton partition wall; 2. Because the lightweight partition board is installed in the non-load-bearing part of the building, the required installation parts are places with large spans, the largest settlement deformation, and the weakest load resistance. Particularity, it is easy to cause cracks at the connection between the board and the board, and the connection between the board and the door and window. When the concentrated load will cause the vibration deformation of the light wall board, cracks and hollowing will occur.
