[0002] With the continuous improvement of people's living standards, the installation of elevators in old communities has become increasingly popular. In the project of installing elevators in old communities, prefabricated steel structures generally only prefabricate steel frames and peripheral maintenance structures. When the shaft and the roof are prefabricated together, since the size exceeds the allowable range of the goods of the transport vehicle, they cannot be prefabricated together. Therefore, the construction of the shaft generally first completes the hoisting and splicing of the shaft and the corridor, and finally manufactures the shaft roof. Mainly, workers stand on the roof to pour concrete and do the waterproof layer, which has potential safety hazards in high-altitude operations and low efficiency. Among them, there is also a method of using a metal roof, but its sound insulation and heat insulation performance are poor, and there are also disadvantages of metal corrosion. Therefore, it is necessary to propose a shaft roof that can be integrally assembled in an elevator shaft for installation to solve the above problems. Summary of the Utility Model
