Method for installing abnormal-shaped extremely-large overhung steel truss under process monitoring construction
The invention discloses a method for installing an abnormal-shaped extremely-large overhung steel truss under process monitoring construction. The installing method includes the steps that a steel structure truss deepening design and structure analysis model is built; steel truss parts are manufactured and pre-assembled, and the manufacturing process and the pre-assembling process are monitored; the steel truss is installed in site in a sectioned mode, and the steel truss installation process is monitored; unloading construction is carried out on the steel truss, and the steel truss unloading process is monitored; loading forming is monitored in the later period after the steel truss is installed in a staged mode; the structure of the steel truss is checked and accepted. The installation technology that a temporary supporting system and altitude spread assembling are combined is adopted, the large-span abnormal-shaped space lattice pipe truss is accurately installed, and the truss is evenly stressed and is not prone to deformation in the installation process. Heat accumulation, welding stress and welding deformation are prevented with the altitude spread roof-member method.
