[0001] The utility model relates to a protective platform for the inner protective layer of an assembled elevator shaft, belonging to the technical field of building construction safety protection. Background Art

[0002] In construction, the protection of elevator shafts is the top priority of construction safety protection. There are many existing construction methods for the construction of elevator shafts in high-rise buildings, such as sliding formwork, climbing formwork, integral lifting inner steel formwork, bamboo and wood combination large formwork, etc. The concrete cylinder of the elevator shaft is a hollow structure. During construction, it is necessary to provide anti-fall safety protection and construction platforms for the construction workers on the inner wall of the shaft. At present, the known protection layers in elevator shafts are mostly the following two types: a safety net is set up by cantilevered steel pipe scaffolding in the elevator shaft. This protection method has a cumbersome erection process and high labor intensity for operators. There are high safety hazards for operators during the erection process, and there are high safety hazards for the protective layer. At the same time, the horizontal steel bars of the floor slab are tied in the protective layer elevator shaft to form protection, and the steel bars in the shaft are removed later. This protection method has high safety hazards and wastes materials when the protection is removed later. Utility Model Content
