Although this project has a special-shaped structure, the installation method is basically the same as other grid installations. The key processes of installation, the installation method, the installation partition and the installation direction are determined.
The roof space frame type of the university library is bolted ball joints and is placed in a square pyramid; the supporting form: multi-point support around the lower chord.
The canopy for the grandstand of the large stadium is crescent-shaped on the plane, 183.5m long, 39.6m wide at the widest point, with a maximum cantilever of 30.0m, fan-shaped laterally, and a sagittal height of 24m.
The application of inclined trusses has altered the unidirectional load characteristics of ultra-large-span maintenance hangar roofs, enhancing the spatial load-carrying capacity of the roof and effectively reducing the burden on the door-side trusses, making the construction of large-span maintenance hangars in extremely low height restriction areas feasible.
According to the layout characteristics of the roof steel truss structure system, the construction technology of "hydraulic synchronous push and slip" is proposed to adopt the installation method of bidirectional rotation and cumulative slip.
