Technical Field

[0001] The utility model relates to the technical field of protective fences, in particular to a scaffolding protective fence with an anti-falling function. Background Art

[0002] As an indispensable temporary working platform in construction, the safety of scaffolding is of vital importance to construction workers. In order to prevent and reduce the risk of falling during high-altitude operations, special protective measures are usually set up on the scaffolding. The protective fence should have sufficient strength and stability to withstand various loads during construction and remain stable and not deformed. It should be equipped with effective mechanical anti-fall devices, such as blocking anti-fall devices, to ensure that they can function under lifting and use conditions. There should be no less than two anti-fall devices at each lifting point. The installation and removal of protective fences must comply with relevant specifications and operating procedures to ensure the safety of workers. All design and construction measures should comply with national or regional construction safety regulations, such as mandatory standards such as the General Specifications for Construction Scaffolding. The protective fence should be able to adapt to different construction environments and needs, and may include multiple specifications and movable designs to cope with different construction site conditions. Scaffolding protective fences can effectively improve the safety level of the construction site, prevent casualties caused by falling, and protect the lives of construction workers.
