Abstract:
Lower string cast steel node installation of a huge string truss in a stadium project is taken as an example to analyze the installation of cast steel node. After field measurement, it is proved that installation accuracy of lower string cast steel of huge truss successfully meet the requirements for installation of fixed roof steel structure. The installation method could effectively satisfy practical construction conditions, providing great convenience for installation of steel rod and subsequent construction. During construction, temporary supporting is used effectively, construction cost is reduced and requirements for environmental protection are satisfied.
