Abstract

The invention discloses a safety construction method for a hoistway elevator, a climbing frame and a construction elevator are arranged in a hoistway, and the construction method comprises the steps that a construction elevator assembly is transported into the hoistway, and a protection device is erected above a construction elevator installation area in the hoistway; a construction elevator is installed in the area below the protection device, and a climbing frame is synchronously constructed above the protection device; and after the construction elevator is assembled, the climbing frame is installed and the bottom of the climbing frame is closed, the supporting scaffolds, the horizontal steel beams and the protection devices are disassembled, and the protection structures on the truss structures provide safety protection for the construction elevator. According to the method, in the construction stage, synchronous construction of a construction elevator and a climbing frame can be guaranteed through an erected protection device; in the operation stage, safety protection is provided through a protection structure on the construction elevator, and the elevator car is prevented from being directly hit by falling objects. By means of the construction method, the problems that an existing safety protection device needs to be installed and dismantled repeatedly, so that procedures are complex, efficiency is low, and safety risks exist can be solved.

Description

technical field [0001] The invention relates to a safe construction method of a hoistway elevator, belonging to the technical field of construction elevators. Background technique [0002] During the construction of the hoistway elevator, since there is usually a climbing frame for the hoistway construction above it, the safety protection of the top of the elevator is the top priority of on-site construction management and control. Under normal circumstances, engineering projects will use pre-embedded steel mesh or set up steel scaffolding for protection. However, as the construction height of the hoistway increases, the elevator needs to be climbed with additional joints. At this time, the upper protective structure needs to be removed and the protective structure re-constructed. Repeated installation and removal of the protective structure will lead to complex construction procedures and low efficiency. Certain construction safety risks exist in certain specific stages. ...
