In order to achieve rapid construction of the smoke exhaust system and rapid installation of the chimney, in the existing smoke exhaust system, a multi-section prefabricated chimney can be used for assembly and use. The prefabricated chimney has the advantages of high installation efficiency, low cost and strong environmental adaptability. It can be installed indoors, outdoors and in other complex environments. In order to reduce the impact on the indoor space, the installation route of the prefabricated chimney is often installed along the indoor top. Since the indoor roof has a certain height, during the splicing operation of the prefabricated chimney, it is necessary to use ladders, lifting platforms or cranes and other equipment to assist in lifting the prefabricated chimney for splicing.
