Composite sound barrier plate
The invention discloses a composite sound barrier plate, and belongs to the technical field of sound absorption and insulation and noise reduction. The composite sound barrier plate comprises a metal shell formed by connecting a perforated panel, a back plate and a frame structure, the frame structure comprises two vertical beams, a top cross beam and a bottom cross beam, and the top cross beam and the bottom cross beam are fixedly connected with the perforated panel and the back plate respectively; a sound absorption cotton/plate is arranged in the metal shell and comprises a bottom plate and a sound absorption wedge integrally formed with the bottom plate; and a plurality of wavy bent surfaces are arranged on the perforated panel and are in contact with the inclined surfaces of the sound absorption wedges. A plurality of sound absorption holes are formed in the wavy bending surface; an elastic supporting metal net is arranged between the back plate and the sound absorption cotton/plate. The sound absorption device has the beneficial effects that the elastic supporting metal net can be conveniently mounted on the back plate and plays a role in stably supporting the sound absorption cotton/plate; the sound absorption wedges in the sound absorption cotton/board enhance the sound absorption effect of the composite sound barrier board.
本发明公开了一种复合声屏障板，属于吸隔声降噪技术领域。复合声屏障板包括带孔面板、背板和框架结构连接形成的金属壳体，框架结构包括两个竖梁、一个顶部横梁和一个底部横梁，顶部横梁和底部横梁分别与带孔面板和背板连接固定；在金属壳体内设置有吸声棉/板，吸声棉/板包括底板和与底板一体成型的吸声尖劈；带孔面板上设置有若干波浪状弯折面，波浪状弯折面与吸声尖劈倾斜面相接触。波浪状弯折面上设置有若干的吸声孔；背板和吸声棉/板之间设置有弹性支撑金属网。有益效果在于：弹性支撑金属网能够方便地安装在背板上，对吸声棉/板起到稳定支撑的作用；吸声棉/板中的吸声尖劈增强了复合声屏障板的吸声效果。
