They are widely used in critical areas such as around foundation pits, building edges, material storage areas, and construction access routes. Their core function is to isolate hazardous construction areas from non-working areas, guide personnel and machinery to pass through in an orderly manner, and prevent unauthorized personnel or equipment from accidentally entering risky areas, providing a fundamental guarantee for personnel safety and operational order during construction. As the pace of construction accelerates, on-site work areas are often dynamically adjusted according to the construction progress, placing higher demands on the ease of transportation, spatial adaptability, and deployment efficiency of temporary safety barriers. They must be able to adapt to the spatial changes required at different construction stages, save storage space during transportation, and improve transfer efficiency, thereby better coordinating with the construction process and supporting overall construction safety management and efficiency improvement.

[0003] Based on the above, there are multiple pain points in the current temporary safety guardrails used in construction: traditional fixed guardrails are heavy, occupy a lot of truck space during transportation, and are inefficient for manual handling; existing folding guardrails are still long and narrow after folding, have limited storage size reduction, and lack a fixed locking structure, making them easy to loosen when stacked; their protective function is limited to physical isolation, lacking active warning and anti-climbing design, and many related safety accidents are related to this; in addition, the flat base is prone to tilting on uneven ground, requiring additional treatment. Utility Model Content
