Vertical metal sound barrier unit plate
The invention provides a vertical metal sound barrier unit plate which comprises a sound absorption module, a perforated panel is arranged on the side, facing a sound source, of the sound absorption module, the perforated panel is provided with a first perforated plate and a second perforated plate, the first perforated plate is located above the second perforated plate, and the second perforated plate is located above the first perforated plate from top to bottom in the height direction. The first perforated plate is gradually far away from the sound absorption module, the second perforated plate is gradually close to the sound absorption module, the lower end of the first perforated plate is connected with the second perforated plate, and a rain cover is arranged on the outer side of an orifice of a first hole formed in the first perforated plate. According to the vertical metal sound barrier unit plate, cotton volume weight increase, load increase and mildew aging caused by water seepage of the sound absorption module can be avoided, the sound absorption effect is improved, and the service life is prolonged.
本发明提供一种直立式金属声屏障单元板，包括吸声模块，所述吸声模块朝向声源的一侧设有穿孔面板，所述穿孔面板具有第一穿孔板、第二穿孔板，所述第一穿孔板处于所述第二穿孔板的上方，沿着高度方向自上而下，所述第一穿孔板逐渐远离所述吸声模块，所述第二穿孔板逐渐靠近所述吸声模块且所述第一穿孔板的下端与所述第二穿孔板连接，所述第一穿孔板上具有的第一孔的孔口外侧设有挡雨罩。根据本发明，能够杜绝所述吸声模块渗水导致棉容重增加、荷载增加、产生霉变老化，提高吸声效果及使用寿命。
