Installation method of prefabricated wall panels for fabricated building

The invention belongs to the technical field of fabricated buildings, and in particular relates to an installation method of prefabricated wall panels for a fabricated building. The method comprises the following steps: surveying and setting out, installing a building device, lifting the wall panels, unhooking, correcting the wall panels positioning, and correcting the verticality of the wall panels; by drawing a marking line of the building device during surveying and setting out, the positioning of the building device and the installation position is guaranteed, so that the positioning of the wall panels and the ground is further guaranteed; the positioning of the wall panels and the ground is realized by means of the positioning of the wall panels and the building device in a lifting process, so that the lifting positioning is quick and simple; furthermore, the wall panels are fixed by means of the building device, so that unhooking operation can be carried out in advance, the occupation of lifting time du
