Description

Technical Field

[0001] The utility model relates to the technical field of construction site safety management, in particular to a guardrail. Background Art

[0002] Construction site safety management involves rationally planning the construction site layout, ensuring unobstructed access, complete and prominent firefighting facilities, and safety warning signs. Different functional areas, such as work areas, material storage areas, and living areas, are divided to avoid interference and potential safety incidents. These areas are typically separated by protective fencing.

[0003] Existing guardrails are generally fixed length or retractable guardrails. Such guardrails are generally of a fixed height and cannot be changed, so it is inconvenient to use when guardrails of different heights are needed. In addition, since the overall height is consistent, they occupy a large vertical area when stored, which makes storage more inconvenient.

[0004] Therefore, the utility model provides a guardrail to solve the above problems. Utility Model Content
