Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering scaffolding, in particular to a scaffolding device with a detachable safety net. Background Art

[0002] When traditionally erecting scaffolding, a close-mesh filter or metal safety net is generally used for external enclosure. The general work steps are: erecting vertical poles → installing horizontal poles → installing scissor braces → laying scaffolding boards → installing skirting boards → installing and securing the filter or safety net enclosure. When using a close-mesh filter as a safety net, iron wire is generally used to secure the safety net to the steel pipe frame. The close-mesh filter is made of a soft material and deforms significantly when in contact with foreign objects. Furthermore, iron wire fixation is difficult to withstand large impact loads and is prone to breakage after aging. When using a metal safety net, an additional safety net fixing bracket is required, which is more complicated to install. Furthermore, depending on the required enclosure strength, the frame size of the metal safety net varies to accommodate the different enclosure strength requirements. Summary of the Invention
