Technical Field

[0001] The utility model belongs to the technical field of protective devices, and more specifically, particularly relates to a protective net for construction engineering. Background Art

[0002] In the process of construction projects, safety has always been the most important. Ensuring safe construction and site safety is the foundation of construction projects. In the process of construction, for safety reasons, some places are not convenient for random entry and exit of strangers. Some areas need to be isolated to prevent non-professionals from entering. At this time, protective nets are used to isolate them. The use of protective nets can facilitate the isolation of dangerous areas and ensure safety in the construction process to a certain extent.

[0003] However, the protective nets of existing construction projects mostly use a structure consisting of a net body and columns to form the main structure of the protective net. The protective nets are generally installed by welding or threaded connections, which is inconvenient to install or disassemble, reducing the practicality of the protective nets.
