AI Technical Summary

Technical Problem

Existing crash-resistant construction site guardrails require an increase in the concrete area on the ground during installation, which increases installation costs.

Method used

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.

Benefits of technology

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.

Abstract

This utility model relates to the technical field of guardrails, specifically an anti-collision construction site guardrail, comprising a base and fixing holes. The base has fixing holes machined into its inner wall. The upper end of the base is threadedly connected to a guardrail. The upper end of the guardrail has a slot, and a fixing mechanism is connected to the upper end of the slot. The guardrail is screwed into the base via its lower thread, and a connecting plate's lower insert is inserted into the slot at the upper end of the guardrail. An external bolt thread passes through the base and connects to the connecting rod. After assembly, the arc-shaped plate on the ring extends the front end of the guardrail for anti-collision protection. The rubber sleeve outside the arc-shaped plate provides cushioning, reducing the area between the lower end of the base and the concrete ground without compromising cushioning, thus lowering installation costs.
