Description

Technical Field

[0001] The utility model belongs to the technical field of construction safety, and particularly relates to a building construction safety anti-falling device. Background Art

[0002] Most of the safety accidents in the construction industry are caused by high-altitude falls and falling object strikes. After the main structure of the building is completed, it is necessary to remove the scaffolding and safety nets on the exterior wall of the building, and then carry out secondary structure and exterior wall construction.

[0003] In the prior art, generally, a scaffolding is directly built on the outer side of the bottom of the building. A horizontally arranged safety net is laid on the scaffolding, and there is a spacing for pedestrians to pass between the safety net and the ground. The scaffolding not only provides installation support for the safety net, but also provides a platform for construction workers. The safety net is used to catch falling objects and prevent falling objects from injuring pedestrians. Since the working height of construction workers is relatively high, usually more than 2 meters, it is necessary to tie a safety rope to the construction workers. When a construction worker falls downward from the outer edge of the scaffolding, the vertically upward pulling force provided by the safety rope can effectively prevent the construction worker from being injured due to a high-altitude fall to the ground. However, at this time, the construction worker is suspended in mid-air, which is not only easy to collide with the scaffolding, but also needs to be rescued by other personnel to get out of trouble.
