KEY CONSTRUCTION TECHNOLOGY FOR LARGE-SPAN STEEL STRUCTURE IN THE BLIND AREA OF LIFTING
With the urban renovation more and more stadiums have been completed,and long-span steel structures have undergone significant changes.The Citizen Fitness Stadium in Tai'an has a steel-concrete structure.Its steel roof consists of the beam string structure and orthogonal single-beam structure.The internal beam string structure is a long-span steel structure with a span of 42 m.In the conventional construction method,one tower crane should be set up nearby,which increases the costs.If a mobile crane is used,one large mechanical crane is required,which will also increase the costs.Accordingly,a series of construction measures should be taken based on the actual situation and engineering characteristics of the project during the construction of large-span steel structures in the blind area of lifting,in order to ensure the construction quality,reduce costs and improve the construction efficiency.
