With the continuous aggravation of domestic population aging, part of old communities are not provided with elevators, so that residents are difficult to travel daily, and in order to solve the daily travel difficulty of the residents in the old communities, the government advocates the transformation of the old communities and the installation of an elevator shaft. The existing elevator shaft installing mode comprises a traditional cast-in-situ construction mode and a steel structure glass curtain wall mode, for example, a traditional cast-in-situ reinforced concrete elevator shaft is adopted, the elevator shaft is required to be built layer by layer, the support is required to be disassembled and assembled repeatedly, the construction period is long, construction dust and construction noise are large, and the elevator shaft is seriously disturbed by people; if adopt steel construction glass curtain wall elevator shaft, though construction cycle is short, construction noise is little, but steel construction easily takes place corrosion, and fire resistance is poor, need do anticorrosive fire prevention processing every few years, and later maintenance cost is high, in addition, in the transportation about the elevator box, produces vibration load to steel construction, vibration noise is big.
Along with the continuous development of constructional engineering, the prefabricated building is widely applied to various building fields, namely, the prefabricated building only needs to be assembled and lapped on site, and additional formwork pouring concrete is not needed. The assembled building construction form can well shorten the construction period, reduce the waste of building construction materials, save manpower and material resources and save resources. However, when an elevator is additionally installed for the transformation of an old community, the balcony width of the old community is not standardized, the existing prefabricated assembly type balcony is assembled after the prefabricated members are separately produced, the procedure is complex, and the prefabricated assembly type balcony cannot be accurately connected between an elevator shaft and a building. So that the construction procedures are complicated, the standardized operation is different, and the construction period is prolonged. Especially in the standard quantitative production process of mill, the mould adjustability is relatively poor, can't carry out swift formula to old district balcony width, causes the commonality relatively poor, and later stage and elevator shaft's beam column installation match inaccurately. In addition, in order to ensure proper temperature in the elevator shaft and reduce noise generation, the conventional elevator shaft adopts full concrete prefabrication, so that a single section of shaft is overweight, and the hoisting difficulty and prefabrication cost are greatly increased; when the single section well of deliberate weight reduction through modes such as trompil, cause the elevator shaft inside not possess the heat preservation effect, receive external cold and hot influence great, influence equipment operation, produce great noise when elevator equipment operation simultaneously and leak, influence result of use is unfavorable for the popularization of outer dress elevator.
