| Abstract: | A reasonable scheme for controlling the welding deformation of the steel box beam is put forward through the research on the practical steel structure of an exhibition hall of certain exposition centre.An overall optimization about the welding technology of the steel box beam is proceeded.The selection of specialized frocks and jigs as well as the effective precautious measures are the resultful means in controlling the welding deformation,achieving the construction precision and meeting the quality requirement of the project.The checking against the steel box beam after completing the project proves that various measures taken bring the expected effect,since each technical index of the design requirement is reached. |
