Usually, when in use, the guardrails are fixed around the construction site with screws to protect the construction site and prevent people from walking into the construction site without paying attention, causing potential safety accidents.

[0003] For example, a guardrail for a construction project with publication number CN211173376U has a guardrail rod installed in the middle of the guardrail frame of the utility model, and a luminous coating is coated on the guardrail rod. The luminous coating improves the warning effect at night, and a warning sign is welded to the middle of the guardrail rod. The warning sign can be used to warn the construction area, thereby increasing the warning effect. Articulated frames are installed on both sides of the guardrail frame, and multiple such guardrail frames can be conveniently spliced ​​and combined with each other through the articulated frames, which facilitates the folding and storage of the device and is convenient to carry. Support legs are installed on the warning sign through hinges, and the stability of the guardrail frame support can be enhanced through the support legs.

[0004] During use, the above device connects each guardrail by means of a hinge. When the ground is uneven, one of the connected guardrails will be suspended, resulting in insufficient supporting surface of the guardrail, causing unstable support of the guardrail. At the same time, the hinged guardrail will be in contact with water mist for a long time at the construction site, which will cause the bolts used for the hinge to rust, making it more troublesome to dismantle the guardrail.
