一个提升单元的各层楼板,在提升阶段是通过承重销分別挂在一群悬臂柱的各个高度上(如图Ⅰ)。由于楼板在其平面内的刚度极大,它对柱子起铰接水平联杆作用,因此升板结构在提升阶段可当作多层铰接排架计算。多层铰
Each floor of a lifting unit is hung on each height of a group of cantilevered columns through the load-bearing pin in the lifting stage (see Figure I). Because of the great rigidity of the slab in its plane, it acts as a hinge for the horizontal linkage, so that the riser structure can be used as a multilayer articulated truss during the lifting phase. Multi-layer hinge
