AI Technical Summary
Existing crash-resistant construction site guardrails require an increase in the concrete area on the ground during installation, which increases installation costs.
The guard rod is fixed to the base with bolts by a threaded connection and slot structure. An extension mechanism, including a ring, an arc plate and a rubber sleeve, is set on the guard rod to achieve a soft and hard buffer design, reducing the area occupied by the ground cement.
It reduces installation costs, and through a combination of soft and hard buffer design, it reduces damage to pedestrians and objects during collisions, improves anti-collision performance, and enhances warning effect through reflective strips.
