AI Technical Summary

Technical Problem

Existing elevated sound barriers are prone to vibration under vehicle traffic, wind, or earthquakes, leading to safety hazards such as structural loosening and bolt loosening. Furthermore, their noise reduction performance is affected, resulting in insufficient overall structural stability and safety.

Method used

The triangular support structure, consisting of a rigid base and support columns, combined with adjustment components and threaded connections, provides stable support through the support rod and adjustment knob. Vibration energy is absorbed by airbags and sound-absorbing panels, while light strips provide illumination and guardrails enhance protection.

Benefits of technology

It effectively suppresses structural vibration, improves the stability and noise reduction performance of elevated sound barriers, extends equipment life, enhances safety and nighttime driving safety, and reduces the risk of noise dispersion and structural resonance.

Abstract

The utility model relates to the technical field of elevated sound barrier, concretely is a kind of anti-shaking city elevated sound barrier, the front end of rigid base one is equipped with guardrail, the support column is installed in the top of rigid base one, and the rear end of support column is rotatably connected with adjusting assembly, the periphery of adjusting assembly is equipped with support rod, and support rod and adjusting assembly are screw thread connection;Beneficial effect is that: support column is embedded in rigid base one, rigid base two forms stable triangle structure by support rod and adjusting screw rod support rear end of support column, and rotating adjusting nut can change the length of adjusting screw rod in support rod to adjust overall support length, and the sound-absorbing hole of bottom sound-absorbing board and arc sound-absorbing board effectively absorbs vehicle noise, and arc design further expands sound-absorbing area to reduce noise leakage, and soundproof glass provides peripheral field of view while blocking noise. Each component is connected with support column by interference air bag pad, and the transmission of shock buffering reduces structural shaking.
