Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, specifically to a fall protection structure for scaffolding. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is divided into external scaffolding and internal scaffolding according to its location. Scaffolding can be categorized by material into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and by structural form into pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding. Currently, most scaffolding has been replaced with reusable cylindrical iron poles, reducing weight while maintaining structural strength. Existing scaffolding is typically erected first, then workers climb directly onto it to perform operations, making it difficult to protect them. Improper operation can easily lead to falls from the scaffolding. Therefore, designing a fall protection structure for scaffolding can provide better safety for workers during construction.
