The diagonal steel plate and the both-end stiff steel skeleton flange are full penetration welded into one body, only a small amount of diagonal oblique rib is reserved on both sides of the stiff steel skeleton, and the purpose of conflict treatment of super-dense diagonal oblique rib and stiff steel skeleton is achieved.
