Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a construction site protection isolation device. Background Art

[0002] Protective isolation devices are usually set up at construction sites, such as fences, warning signs, safety nets, cordons, etc. Protective isolation devices can clearly separate dangerous areas from safe areas, reduce the possibility of people and equipment entering dangerous areas, reduce the risk of accidents, and at the same time remind people of the dangers of the construction site, enhance workers' safety awareness, and reduce accidents caused by negligence.

[0003] The existing construction site isolation fence is a relatively common construction isolation device, and the isolation fence is usually composed of several segments spliced ​​together to form a whole. However, since the traditional fence segments are prefabricated and cannot be disassembled, the overall volume is large and inconvenient to transport and transfer. Secondly, some fences are difficult to disassemble and can only be disassembled by destroying certain structures, resulting in the inability to reuse and increasing cost waste. Utility Model Content

[0004] The utility model aims to provide a construction site protective isolation device which is easy to disassemble and assemble and can be reused, and effectively solves the problems raised in the above-mentioned background technology.
