Abstract

The invention discloses a damping load reducing sound barrier including a sound barrier body and sound barrier columns, wherein a damping structure is arranged between the two sides of the sound barrier body and the sound barrier columns. The damping structure is a metal damping structure, and the damping structure includes a damping monomer and a damping support. The damping support is made of U-shaped groove steel, and the opening end of the U-shaped groove steel is used to clamp the two ends of the sound barrier body. A damper is arranged in the U-shaped groove steel, the damper comprises asleeve, an inverted-T-shaped connector and a spring, and the sleeve is arranged in the U-shaped groove steel. The damping load reducing sound barrier is simple and novel in structure, convenient to install and long in service life. The material of the damping structure is metal, the practical performance is good, the price is relatively cheap, the cost performance is high, the influence of the environment is very small, the workload of maintenance personnel is reduced, and the maintenance cost is reduced.

Description

technical field

[0001] The invention relates to a sound barrier, in particular to a damping load reduction sound barrier. Background technique

[0002] With the rapid development of China's economy and the continuous acceleration of urbanization, highways, railways, urban rail transit and other transportation methods have developed rapidly. These roads will inevitably pass through densely populated residential areas during construction, and the traffic noise generated It has brought some interference to the work, life and study of residents near the road. National environmental monitoring results show that: about 17% of cities are moderately polluted in road traffic noise, and 49% are lightly polluted. Building sound barriers to solve traffic noise pollution has become the main way to control urban road noise.

[0003] In recent years, my country has built a large number of high-speed railways and put them into operation. In order to solve the noise pollution caused by the ...

Embodiment approach

[0030] Figures 1-4 show the second embodiment of the present invention: a damping load reduction sound barrier, comprising a sound barrier body 4 and an H-shaped steel sound barrier column 1, on both sides of the sound barrier body 4 A damping structure is provided between the H-shaped steel sound barrier column 1. The damping structure is arranged between the two sides of the sound barrier body 4 and the H-shaped steel sound barrier column 1, so that the force is uniform under the condition of bearing the pulsating load, and the entire sound barrier body 4 and the H-shaped steel sound barrier column 1 serve as A whole to bear the pulsating load, each part is evenly stressed, no local damage will occur, and the maintenance cost is reduced. The damping structure is arranged symmetrically on both sides of the sound barrier body 4, which is convenient for installation and mass production Manufacturing, and save installation time, improve work efficiency and reduce costs.
