At the same time, the performance of the steel structure will not be damaged due to welding, which will reduce the overall strength.
[0026] In some embodiments, a screw hole for installing a bolt 7 is opened on one side of the second connecting member 2, and the stud end of the bolt 7 passes through the screw hole and is installed inside one end of the first connecting member 1.
[0027] It should be noted that the screw holes provided on the second connecting member 2 are used to facilitate the installation of bolts, thereby achieving the connection of the connecting member.
