The prefabricated sound-insulating and heat-insulating prefabricated wall panel for an assembled building is provided with fixing rods, fixing holes, elastic components and fixing bolts. When the prefabricated panels are connected, the connecting heads of the two prefabricated panels are clamped together, and then the fixing bolts are inserted into the through holes and screwed into the corresponding threaded holes, so that the fixing bolts are screwed into the active cavity and squeeze the elastic component, so that the fixing rods extend out of the active cavity and are inserted into the corresponding fixing holes, thereby performing multiple fixed connections on the two connecting heads, making the connection between the two adjacent prefabricated panels more secure.
