The invention relates to an assembled additionally-arranged elevator structure adopted in an existing building and a construction method of the assembled additionally-arranged elevator structure, andbelongs to the technical field of existing building comprehensive transformation. In combination with the existing building comprehensive transformation project, the assembled additionally-arranged elevator structure adopted in the existing building and the construction method of the assembled additionally-arranged elevator structure are provided. An additionally-arranged elevator prefabricated base component, a spliced shaft steel frame and an additionally-arranged elevator prefabricated room panel component are included. The additionally-arranged elevator prefabricated base component is arranged on a pre-prepared cushion layer at the elevator adding position. One sides of shaft steel column lifting lug plates of the spliced shaft steel frame are welded to steel columns of the steel frame, one lifting lug plate is welded to each of the inner side and the outer side of each steel column, and totally eight lifting lug plates are welded to the four steel columns of each joint of shaft steel frame body. A shaft spliced steel frame structure is formed in the manner that the upper-joint shaft steel frame body and the lower-joint shaft steel frame body are spliced through connection of connecting plates and the lifting lug plates. The additionally-arranged elevator prefabricated room panel component is arranged on the additionally-arranged elevator spliced shaft steel frame. The assembled additionally-arranged elevator structure has the most obvious advantages that the construction period is short, the construction speed is increased, accordingly the construction cost is reduced,daily life of original residents is not influenced during construction, and elevator installation is free and flexible.
Description
technical field [0001] The invention relates to an existing building adopting a prefabricated structure with an additional elevator and a construction method thereof, belonging to the technical field of comprehensive transformation of existing buildings. Background technique [0002] Many existing buildings in our country were built in the 1980s and 1990s. At that time, due to the constraints of economic conditions and other factors, the building functions were simple, and the existing buildings with seven floors and below were not equipped with elevators. With the gradual improvement of urban living standards and the continuous improvement of economic conditions, people's requirements for quality of life are also getting higher and higher. At present, in the transformation of existing buildings, these existing buildings have become the key objects of transformation. In order to facilitate the daily life of residents and make them live comfortably and conveniently without i...
