Abstract:A steel structure assembled bed-jig was developed and applied in assembled large-scale steel truss structure such as airports and sports centers. This application greatly facilitates construction technologies such as ground assembly and welding, upright entire assembly, and one-time installation. It can improve the accuracy, the lifting and assembly of large-span cantilever trusses, shorten the construction period and ensure the safety of workers by controuing the construction technology of the hot bending of belfast truss strictly.
Keywords:bed-jig; steel truss structure; hot bending; temporary support
