METHOD OF CONSTRUCTING CYLINDRICAL SHELL GRID STRUCTURE WITH ULTRA-LARGE SPAN

摘要

Disclosed is a method of constructing a cylindrical shell grid structure with an ultra-large span, involving firstly completing the installation of a gable grid structure at one end of the cylindrical shell structure, then taking the gable grid structure as a stable starting unit for the installation of the whole cylindrical shell grid structure, i.e. using the stable starting unit that has already been installed, i.e. the gable grid structure, to bear the construction load, and starting from the gable in the longitudinal direction of the cylindrical shell structure, using an "altitude spread roof member method" to accomplish the subsequent installation of the cylindrical shell grid structure. The method of constructing a cylindrical shell grid structure with an ultra-large span has high construction efficiency, and the advantages of safety, low construction outlay, and high quality.
