The invention provides a hoisting method of a huge thin deck block. The hoisting method comprises the following steps of S1, determining hoisting equipment; S2, determining the number of suspension points connected with each set of suspension rigging; S3, determining the positions of all the suspension points on the same set of suspension rigging; S4, mounting suspension fittings and reverse longitudinal reinforcing ribs; and S5, after trial hoisting, carrying out formal hoisting and carrying of the huge thin deck block. In the hoisting method, the suspension points are evenly distributed based on the structural characteristics of the huge thin deck block and the requirement for the inclination angle of steel wire ropes on the suspension points, the reverse longitudinal reinforcing ribs are additionally installed according to a frame structure formed by ribs and longitudinal ribs on the huge thin deck block and the positions of the suspension points, the deformation amount of the huge thin deck block is controlled while stable and safe hoisting of the huge thin deck block is guaranteed, and it is guaranteed that subsequent carrying is carried out smoothly; and besides, the additionally installed reinforcing ribs do not need to be dismantled subsequently, damage caused by later cutting to the thin deck surface is avoided, meanwhile, the later construction workload is reduced, and then the ship construction efficiency is further improved.
本发明提供一种巨型薄甲板总段的吊装方法,该吊装方法包括以下步骤:S1、确定起吊设备;S2、确定每个吊排连接的吊点数量;S3、确定相同吊排上所有吊点的位置;S4、安装吊码及反面纵向加强骨;S5、试吊后,进行巨型薄甲板总段的正式吊运与搭载。本发明针对巨型薄甲板总段的结构特点,结合吊点上钢丝绳的倾斜角度要求,均匀分布吊点,依据巨型薄甲板总段上肋骨与纵骨形成的框架结构和吊点位置,补装反面纵向加强骨,在保证巨型薄甲板总段平稳、安全吊装的同时,控制巨型薄甲板总段的变形量,保证后续搭载的顺利进行;此外,补装的加强骨后续无需拆除,不仅避免后期切割对薄甲板面的破坏,同时也减少后期施工工作量,从而进一步提高船舶建造效率。
