Abstract:
the banquet hall steel truss belongs to the large-span super-heavy super-high steel truss, the existing hoisting equipment can not meet the overall hoisting requirements, therefore, according to the hoisting equipment hoisting performance, truss installation location and component transportation, welding node complexity and other constraints on the truss installation; steel truss installation need to adopt the support system, through the construction of pre-simulation to develop steel truss installation order, complete the high-altitude in-situ assembly; establish reasonable procedures to ensure the safety and reliability of steel truss and civil cross construction, quality control.
