Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a falling prevention device for steel structure engineering construction. Background Technique

[0002] During the construction of steel structure projects, in order to ensure the personal safety of construction workers, it is necessary to connect the construction workers and other fixed structures through safety ropes to prevent the construction workers from falling from a height during construction.

[0003] For example, Chinese Patent CN218324029U discloses a safety rope hanging device and a falling prevention system. It includes: a combination member, a movable member and a hanging ring. The combination member defines a chamber with through holes on both sides for the external structural member to pass through; the movable member is arranged in the chamber and connected to the combination member, and the movable member can rotate to enable the safety rope hanging device to slide relative to the external structural member; the hanging ring is arranged on the outer surface of the combination member for connecting the safety rope. When the construction worker moves, the hanging device is driven by the safety rope and can slide on the external structural member to expand the construction range of the construction worker.

[0004] However, in the above patent, it is not convenient to disassemble and assemble the first plate member; since the hanging ring is a closed circular ring, after the safety rope passes through the hanging ring, it needs to be locked by tying a knot or using a buckle, which is not convenient for quickly connecting the safety rope and the hanging ring.

[0005] Based on this, the utility model designs a falling prevention device for steel structure engineering construction to solve the above problems. Content of the Utility Model
