Description

Technical Field

[0001] The present invention belongs to the technical field of safety protection rope installation, and in particular relates to a safety anti-fall lifeline system of a steel frame core tube structure and a construction method thereof. Background Art

[0002] During existing high-altitude steel structure construction, safety ropes are often deployed to ensure the safety of construction workers. These ropes are used to secure the safety equipment, ensuring their safety. However, traditional safety ropes are temporarily secured to vertical poles by manually inserting them into the base. The ropes can easily cause the poles to shake when the safety wire ropes slide, endangering workers. The wire ropes between adjacent poles are not continuous, so workers need to unhook and rehook each pole, especially at corners where adjacent beams meet. This requires unhooking and crossing a long distance, posing a significant safety hazard and significantly wasting construction time. Summary of the Invention
