The horizontal and vertical openings of the elevator shaft are independent of each other, which is not ideal in terms of construction time, construction cost, and construction safety. It is also relatively troublesome to dismantle them later. Especially for buildings with high storeys, the protection of the elevator shaft requires the erection of a large number of scaffolding, which is not only time-consuming and labor-intensive, but also prone to instability.
