AI Technical Summary

Technical Problem

The bolt connections of existing steel anti-collision guardrails are easily loosened under long-term vibration and impact, resulting in a decrease in the stability of the guardrails, and the bolts are susceptible to natural factors, shortening their service life.

Method used

A reinforced anchor structure of steel anti-collision guardrail is designed, adopting structural design of positioning parts, protective plates, limit grooves and fixing blocks. Through the coordination of anchor bolts and limit grooves, the clamping of the protective plates and fixing blocks, the limit and fixing of anchor bolts is achieved to avoid loosening, and the design of the protective plates is isolated from external erosion.

Benefits of technology

It effectively avoids the looseness of anchor bolts during long-term use, ensures the stability of the guardrail, reduces safety risks, prevents rust and damage, significantly extends the service life of the guardrail, and improves the overall safety performance of the traffic facilities.

Abstract

The utility model discloses a reinforcement anchoring structure of a steel anti-collision guardrail, comprising a bridge, an anchor bolt and a guard plate, a guardrail base is installed on the bridge through the anchor bolt, a guardrail is arranged on the top of the guardrail base, a pair of chamfers are provided on the guardrail base, two pairs of positioning pieces are provided on the guardrail base, the chamfers are located between the pair of positioning pieces, a pair of limiting grooves are provided at the bottom of the guard plate, and the guard plate slides on the top of the guardrail base, and the structural design of the positioning piece, the guard plate, the limiting groove and the fixing block can play a limiting role on the anchor bolts after installation, effectively avoiding the loosening phenomenon of the anchor bolts during long-term use, ensuring the stability of the guardrail, reducing the safety risks caused by the falling off of the guardrail, and isolating the anchor bolts from the external environment, which can not only prevent the rust and damage of the anchor bolts, but also significantly prolong the service life of the guardrail, and improve the overall safety performance of traffic facilities such as roads and bridges.
