(Problem that the invention aims to solve) When rigidly joining a beam steel frame to a column steel frame with a hollow cross section such as a steel pipe, it is necessary to insert a diaphragm inside the column steel frame in order to reliably transmit the stress from the beam to the column. Alternatively, measures such as protruding stiffeners on the outer periphery are required, but reinforcing materials such as diaphragms are generally difficult to install and tend to complicate the structure, especially when filling concrete into the column steel frame. There is a problem with filling properties.
