[0001] This utility model relates to the field of construction equipment technology, specifically to a sawtooth-shaped protective door for construction elevators on building facades. Background Technology

[0002] With technological advancements and economic development, super high-rise buildings are constantly emerging. As landmarks in modern cities, the unique facade shapes of super high-rise buildings are also constantly pursuing innovation and development. To achieve the unique aesthetic effect of the facade of super high-rise buildings, irregular sawtooth eaves are designed on the facade to provide positions for curtain wall embedded parts. During the construction process, construction elevators need to be installed on the outside of the building. Usually, the elevators are close to the building surface to facilitate the installation of safety doors. However, in the implementation of the above design scheme, the construction elevator needs to be installed at the outer end of the building eaves. As a result, the distance between the inner end of the eaves and the construction elevator is relatively far, and a passageway needs to be connected between the construction elevator and the floor.

[0003] In existing technologies, multiple sets of scaffolding are typically used to erect a frame, then steel plates are laid on the inside of the frame, and protective doors and railings are welded or bolted to the edges of the passageway. This results in the difficulty of installing protective doors for external construction elevators and poses high safety hazards.

[0004] Therefore, it is necessary to invent a sawtooth-shaped protective door for construction elevators on building facades to solve the above problems. Utility Model Content
