Abstract:
In order to satisfy spatial aesthetic requirements, important parts of a large multifunctional hotel, such as banquet hall and lobby, etc., adopt large-span superhigh prestressed frame structure, which has great difficulty in general construction. Large-span superhigh formwork supporting system adopts full hall cuplok steel pipe scaffold and post-tensioning prestressed beam with bond. Manual binding and bidirectional tensioning method are adopted for construction of the prestressed steel bar. Appropriate tensioning equipments are used and special prestressing and tensioning measures are established to ensure the engineering quality.
