Rugao 226500 AAbstract:bstract: Daqing Petroleum Technology Museum hall is a suspended spherical shell grid structure. Due to the narrow construction space, the installation technique of cumulative lifting combined with the ground assembly and the overhead assembly had been applied in which the lower half of the suspended spherical shell grid was initially assembled on the ground , then lifted and installed by the chain hoist which was fi xed to the prestressed steel beams, and fi nally tack-welded in the middle of the steel beam platform. Afterwards, on such platform, the upper half of the spherical shell grid was assembled and installed with the chain hoist which is fi xed to the upper part to complete the cumulative lifting.
