Corner joint structure for assembled building

The corner connector structure comprises a fixing frame, connectors are fixedly welded to the right side and the top of the fixing frame, a first reinforcing disc is fixedly welded to each connector,a connecting inserting groove is formed in each connector, a second flange plate is fixedly welded to an opening in the right end of each connector, and a second reinforcing disc is fixedly welded tothe right end of each second flange plate. The right end of the connector is connected with a connecting piece; a second reinforcing plate is fixedly welded to the connecting piece, a first flange plate is fixedly welded to the joint of the connecting piece and the connector, and the first flange plate and the second flange plate are fixedly connected through a fixing bolt. By means of the reinforcing pull rod used for connecting and fixing between the first reinforcing disc and the second reinforcing disc, the connecting and reinforcing effect between the connector and the connecting piece can be further improved, the
