通常需对预制墙板在悬挑结构下完成吊装时，需先在墙板对应位置的上方楼板进行开孔，汽车吊将预制墙板先吊至墙边竖起斜靠在已完成的结构上，再从上层楼板开洞处将手拉葫芦放下，工人需爬至内墙板顶部，进行脱钩及换成手拉葫芦上的吊钩，再进行预制内墙板安装。预制内墙吊装是受到室内其他结构的影响，当上层结构为悬挑梁或悬挑板时，预制内墙上端操作空间会十分有限，给施工带来难度。Generally, when the prefabricated wall panels are hoisted under a cantilevered structure, holes must be made in the upper floor slab at the corresponding position of the wall panels. The car crane first hoists the prefabricated wall panels to the side of the wall and leaning against the completed structure. , And then lower the chain hoist from the hole in the upper floor. The worker needs to climb to the top of the inner wall panel, unhook and replace it with the hook on the chain hoist, and then install the prefabricated inner wall panel. The prefabricated interior wall hoisting is affected by other indoor structures. When the upper structure is a cantilever beam or a cantilever slab, the operation space at the end of the prefabricated interior wall will be very limited, which will bring difficulties to the construction.
