The invention relates to a method of transforming stiffness pillar cross type steel ribs into stiffness steel tube type steel ribs and transition section thereof. The method includes the steps of 1, installing a stiffness pillar cross type steel rib; 2, installing a stiffness steel tube type steel rib at one end of the stiffness pillar cross type steel rib; 3, arranging transition section at the stiffness pillar steel tube type steel rib and the stiffness cross type steel rib, the transition section comprising a first connecting section, a second connecting section, a first transitional section and a second transitional section, and the first transitional section and the second transitional section being arranged between the first connecting section and the second connecting section; 4, positioning the first connecting section of the transition section with the stiffness pillar steel tube type steel rib and positioning the second connecting section with the stiffness pillar cross type steel rib through positioning clamping plates and 5, connecting a transition section steel tube type steel rib with stiffness pillar steel tube steel ribs in a butt welding mode and connecting a web of the second connecting section of the transition section with a web of stiffness pillar cross type steel rib in a butt welding mode. The technical scheme achieves the transition of stiffness pillar cross type steel ribs and stiffness steel tube type steel ribs.
Description
technical field [0001] The invention relates to the field of construction, in particular to a method for converting a stiff column cross-shaped steel frame into a stiff column steel tube steel frame and a conversion joint thereof. Background technique [0002] Since the cross-shaped steel frame of the stiff column and the steel tube steel frame of the stiff column can effectively reduce the cross-section of the member, reduce the amount of structural reinforcement and have good seismic performance in the main structural system of the building, the advantages of the rapid development of the construction industry are also becoming more and more obvious. Promote the theoretical research and engineering practice of steel and concrete composite structures. The engineering applications of stiffened column cross-shaped steel frame and stiffened column steel tube steel frame are becoming more and more extensive. However, at present, both stiffened column cross-shaped steel frame and...
