Urban overhead ventilation type combined sound barrier
The invention relates to an urban overhead ventilation type combined sound barrier. The combined sound barrier is characterized in that a first-class sound absorption and insulation unit plate, a second-class sound absorption and insulation unit plate and a top end noise reduction plate are located in the middle, the lower portion and the top of the sound barrier respectively, and the first-classsound absorption and insulation unit plate has a ventilation effect. The working power of the ventilation structure comes from a wind load and the dead weight of a movable noise reduction plate, the wind load can drive the noise reduction plate to rotate, the dead weight can enable the noise reduction plate to be reset and closed, the rotating angle can be calculated according to the wind load andthe dead weight of the noise reduction plate, and the load reduction rate can be guaranteed. Different rotating angles can be obtained by changing the dead weight and the windward area of the noise reduction plate, so that different load reduction rates are achieved.
本发明涉一种城市高架通风型组合式声屏障，其特征在于：一类吸隔声单元板、二类吸隔声单元板和顶端降噪板，分别位于声屏障的中部、下部和顶部，其中一类吸隔声单元板具有通风作用。通风结构的工作动力来源于风荷载和活动式降噪板的自重，风荷载可驱动降噪板转动，自重可使降噪板复位闭合，且转动角度可由风荷载和降噪板的自重计算得出，减载率可以得到保证；通过改变降噪板的自重和迎风面积可获得不同的转动角度，进而达到不同的减载率。
